Abstract
In spite of several innovative measures in the United States (U.S.) healthcare industry, the
industry is not only lagging behind other industries in its technology adoption, but also in
ensuring basic safety and healthcare quality (Landro, 2001). The healthcare information systems
(HIS) can provide financial and qualitative benefits to the healthcare industry (Wickramasinghe,
Fadlalla, Geisler, & Schaffer, 2003). However, the HIS literature review has indicated a lack of
cost-effective HIS model with uniform healthcare information standards and quality measures, in
the U.S. healthcare information technology documentation. The purpose of this study was to
construct and evaluate the Electronic Health Record (EHR)-centric model to monitor a
predefined set of healthcare quality goals. The quantitative research methodology, strategic
contingency theory of organizational management, and economic value-added concepts of HIS
planning have been applied. Secondary survey data from 1999 to 2004, collected by the
American Hospital Association (AHA) annual survey of hospitals and the Dorenfest Integrated
Healthcare Delivery Systems (IHDS), have been used to determine statistical significance of the
proposed critical success factors of healthcare quality in small, medium, and large size healthcare
organizations. The findings have provided a planning structure for healthcare organizations and
new understanding in healthcare information technology management fields, for improving
quality of the healthcare services.

CHAPTER 1. INTRODUCTION
Introduction to the Problem
The healthcare industry is an economically and socially significant portion of the United
States (U.S.) industry sector. The industry represents a fifth of the U.S. economy and carries
social significance due to its ongoing focus on quality of the services. However, the healthcare
industry is not only lagging behind other industries in its technology adoption, it is also behind
other high risk industries in ensuring basic safety and healthcare quality (Landro, 2001). While
the U.S. healthcare "absorbs more than $1.7 trillion per year--twice the Organization for
Economic Cooperation and Development (OECD), average-premature mortality in the country is
much higher than OECD averages" (Hillestad, Bigelow, Bower & Girosi, 2005, p. 1103).
The Institute of Medicine (IOM) committee on quality healthcare in America has taken
initiative steps on healthcare quality since 2000 (Sokol & Molzen, 2002). The IOM committee
presented a series of quality reports identifying gaps in healthcare quality in areas including
healthcare information systems (HIS) and patient safety (Swan, Lang & McGinley, 2004). As per
the IOM report, errors in the healthcare industry are due to failures in organizational systems and
various organizational factors. The IOM and the Joint Commission on the Accreditation of
Healthcare Organizations (JCAHO) are trying to implement error-reducing processes. In a series
of reports, IOM recommended implementing an electronic health record program (EHR) to
achieve effective coordination of clinical services and in turn to improve healthcare quality
(IOM, 2001, 2003b). At present, when several healthcare practitioners treat a patient, they often
8/9/2019 Vinata_KulkarniPhD
15/196

do not have complete information about the medicines prescribed or details about their patient's
illnesses.Most medical records are still stored on a paper, which makes it difficult to properly
coordinate care and provide detail information to the consumers about healthcare costs or quality
and to make informed decisions about their care (Hillestad, et al., 2005).
Healthcare literature indicates the existence of some healthcare errors due to scribbled
writing in medical records and prescriptions that resulted in administration of a drug for which
the patient had a known allergy. Lesar, Ben, and Henry (1997) pointed that if healthcare
providers have timely information about their patients and the prescribed medication with the use
of computerized systems and EHR, many of these errors could be avoided.Another important
current issue observed is that segments of the healthcare industry and individual providers have
adopted technology at different rates and a gap is widening between the most wired and the
least wired providers (Solovy, 2000).According to Hillestad et al. (2005, p. 1104), "the U.S.
trails a number of other countries in the use of EHR. Only 15-20 % of the U.S. physicians'
offices and 20-25 % of hospitals have adopted such systems." Thus, in spite of several innovative
measures in the U.S. healthcare industry, there are still many barriers in EHR implementation
that include high costs, a lack of certification and standardization of IT tools, and an inadequate
HIS infrastructure. HIS cost reduction and improvement in quality of services are two important
issues of the U.S. healthcare industry while implementing EHR.
Background of the Study
As per GAO Report (2004, para.1), from 1992 to 2002, the U.S. healthcare spending
"increased from $827 billion to about $1.6 trillion and it is expected to nearly double to $3.1
trillion in the subsequent decade." The Peirce (2004) analysis of cost and wages indicated a rapid
8/9/2019 Vinata_KulkarniPhD
16/196

increase in medical costs compared to that in wages, which is a threat to the global
competitiveness of the United States. Although the United States leads the world in per capita
medical spending, life expectancy of people in the U.S. is approximately same as Cuba's and
significantly behind nations such as France, New Zealand, Spain, and Singapore (Peirce, 2004).
High healthcare costs, errors in medical data recording systems, administrative inefficiencies,
and lack of system coordination are some of the concerning issues of the U.S. healthcare
industry. According to the estimates made by the IOM, there are some 44,000 losses of human
life in the U.S. hospitals each year, and there are more losses of life due to medical mistakes than
from highway accidents, breast cancer, or AIDS each year (Tickner, 1999). According to the
IOM report, the total national cost for adverse events is estimated to be between $37.6 and $50
billion. Also, at present, the application of health information technology (HIT) to clinical
records is quite slow.
Thus, at present, an integration of HIT into the nation's healthcare system seems quite
inadequate (White House Statement, 2004). There is variation in the healthcare quality within
and across communities, hospitals, practitioners, patients, delivery systems, geographic areas,
and health problems. Researchers have demonstrated that even for the same groups, healthcare
quality performance varies considerably at different times and situations, which makes it difficult
to develop programs to improve healthcare quality based on the current knowledge. Teisberg,
Porter, and Brown (1994, p. 131) suggested innovation as "the fundamental driver of continuous
quality improvement and cost reduction." Thus, considering the seriousness of medical errors
and the technology potentialto decrease medical errors, the healthcare industry needs a specific
guideline for reducing cost and improving quality of the healthcare.

Many accreditation agencies, state governments, business coalitions, and U.S.
government agencies are proposing solutions to decrease the medication errors. The Agency for
Healthcare Research and Quality (AHRQ) designed the national healthcare disparity report
(NHDR) and national healthcare quality report (NHQR) to provide policy makers with snapshots
of disparities and quality of healthcare in the U.S. (Moy, Dayton, & Clancy, 2005). One of the
objectives of the IOM Report was to establish a national goal of reducing the number of medical
errors by 50% over 5 years (Kohn, Corrigan, & Donaldson, 2000). To accomplish this goal and
to reduce the medical mistakes, the healthcare advisers have created a four-tiered framework.
The framework includes establishing a national focus to create leadership, research, tools, and
protocols to enhance the knowledge base about safety; identifying and learning from medical
errors through mandatory and voluntary reporting systems; raising standards and expectations for
improvements in safetythrough the actions of oversight organizations, group purchasers, and
professional groups; and implementing safe practices at the delivery level.
On January 27, 2005, the U.S President took an important step in the nation's health IT
plan by signing the electronic prescribing (e-prescribing) proposed regulation by the Centers for
Medicare and Medicaid Services (CMS) at the Department of Health and Human Services
(HHS). Also, recently the U.S. President signed the new Patient Safety and Quality Improvement
Act (White House, 2005) with an objective to create an incentive for healthcare providers to
report medical errors to a centralized database. By April 2006, "new healthcare information
security provisions designed to protect data transmitted and stored electronically will go into
effect under the Health Insurance Portability and Accountability Act (HIPAA) medical privacy
law"(Swartz, 2004, p.26). The U.S. national healthcare plan is to facilitate EHR to most
8/9/2019 Vinata_KulkarniPhD
18/196
5
Americans within the next 10 years.Consequently the objective of EHR implementation is to
achieve expected qualitative benefits, such as easy storage and access to medical information,
prompt response in medical services, elimination of errors and duplicative testing due to lost
laboratory reports, patient safety, and reduction in time and cost of the healthcare services.
Statement of the Problem
The problem in the U.S. healthcare industry, while emphasizing HIT documentation is a
lack of an EHR-centric, cost effective HIS model with uniform healthcare information standards
and pre-defined healthcare quality measures. Though several promising efforts and many
innovative measures are in progress for broader adoption of EHR across the entire U.S.
healthcare system, there are some barriers in attaining desired efficiency of services of the
healthcare systems while implementing EHR. Kibbe (2004, para. 5)evaluated key barriers to the
deployment of EHR at the national level such as "high prices, risk of implementation failure,
lack of connectivity and interoperability, confusion about the product and company reliability for
EHR, and variation in HIS and healthcare business practices." According to Maffei (1997),
though nature of the healthcare industry is basically customer service oriented, for the past
decade, focus of the U.S healthcare services is not only caring for the sick and injured, but also
preventing illness and injury, and reducing clinical errors in the healthcare practices Thus,
nationwide emphasis on HIT documentation and implementation of EHR has established a need
for an IT based model to help document, categorize, control, and transfer knowledge while
attaining the healthcare quality.

Purpose of the Study
The purpose of this study was to construct and evaluate a conceptual HIS model for EHR
implementation and suggest outcome measures to monitor the healthcare quality. The underlying
key to gaining the healthcare quality improvement is identifying critical success factors for
strategic HIS management during EHR implementation (Baker & Pink, 1997; Zani, 1970). With
a focus on predefined healthcare quality goals, the model is built on strategic contingency theory
of organizational management and economic value added concepts of IS planning.
Rationale
One of the advantages of good information systems (IS) is that these systems facilitate
healthcare providers in creating a budget and accurately calculating the costs to treat a group of
patients (Montague, 1994). EHR is one of the useful repository sources for documentation of a
patients medical information and healthcare outcomes that can capture required data and display
it to make timely decisions on healthcare. Brailer and Von Horn (1993) suggested investment in
employee education because more and more employees are getting involved in the control of
healthcare delivery that implicitly involves providing consequential information and relevant
data. Porter and Teisberg (2004) recommended a collection and wide distribution of standardized
healthcare information about individual diseases and treatments that would facilitate patients to
make informed choices about their care. According to Porter & Teisberg (2004), setting up a
transparent billing and pricing mechanisms by payers, providers, and health plans would reduce
cost, confusion in data handling, pricing inequality, and other possible inefficiencies in the
system. Thus, effective development methodology and business processes with HIS architectural
8/9/2019 Vinata_KulkarniPhD
20/196

vision could be the key factors to implement and evaluate EHR in view of the associated costs,
benefits, risks, and predefined values.
Research Questions
While the U.S. healthcare costs are constantly escalating, there is also an increase in the
healthcare budget at the national level to expedite development and adoption of EHRs and
supporting technologies. As per the press release on October 13, 2004, The U.S. Department of
Health and Human Services announced $139 million in grants and contracts to promote a use of
health information technology (HIT)"(Anderson, 2004, p. 3).Consequently, as pointed by Al-
Faris (1995, p. 24), "the fundamental challenge to IS decision makers is how to sustain quality of
patient care delivery while earning profit." The implicit questions examined in the study are:
1. How can cost effective and value added healthcare quality be achieved through
strategic healthcare information management (HIM) while implementing EHR?
2. What are the critical success factors for achieving the healthcare quality while
implementing EHR?
Significance of the Study
Although the healthcare literature indicates varied strategies about classification of
medical errors, including types of healthcare services provided, severity of the resulting injury,
legal definition, type of setting, and type of the individual involved, to the best knowledge of this
author, those strategies lack a common framework. According to Borel and Rascati (1995),
researchers, healthcare providers, various healthcare agencies, and related businesses have tried
to develop their own solutions to decrease clinical errors. Kettelhut (1992, p. 18) suggested,
"Hospitals and clinics must upgrade feedback and control systems in order to track costs,

Acute care hospital. As per the description in Dorenfest database, it is a healthcare
facility that "services individuals with less than chronic diseases on an inpatient basis."
Sub-acute care hospital. According to the description in Dorenfest database, a healthcare
facility that "services individuals with chronic diseases: long-term, skilled nursing, behavioral
health, psychiatric facilities, inpatient hospice."
Ambulatory care hospital. According to the description in Dorenfest database, it is a
healthcare organization that "offers preventive, diagnostic, therapeutic, and rehabilitative
services to individuals not classified as inpatients or residents. This category also includes
physician offices."
Information systems. Hirschheim, Klein, and Lyytinen (1995) described information
systems (IS) as "a technologically implemented medium for recording, storing, and
disseminating linguistic expressions, as well as for drawing conclusions from such expressions."
Information systems application. Ferrand and Lay (1994) described an IS application as
an integrated group of computer programs and associated data that support end-users in carrying
out one or more of their business functions.
Healthcare information systems. The National Library of Medicine (Medicare Payment
Advisory Committee, 2001) defined healthcare information systems (HIS) as integrated
computer-assisted systems to store, manipulate, and retrieve healthcare administrative and
clinical data.
Data and information. Though the term data and information are often used
interchangeably, as per Tan (1995),data are primary building blocks of HIS while information is

Medicare HMO. This is"the HMO that has contracted with the federal government under
the Medicare Advantage program to provide health benefits to persons eligible for Medicare who
choose to enroll in the HMO, instead of receiving benefits and care through the traditional fee-
for-service Medicare program" (Medicare HMO, n.d.).
HIPAA. HIPAA is the acronym for the Health Insurance Portability and Accountability
Act of 1996. The Center for Medicare & Medicaid Services (CMS) is responsible for
implementing various unrelated provisions of HIPAA. The administrative simplification
provisions of the HIPAA of 1996 (HIPAA, n.d.) require the Department of Health and Human
Services to establish the national standards for electronic healthcare transactions and national
identifiers for providers, health plans, and employers. HIPAA also addresses patients' safety and
security and privacy of health data (CMS, 2005).
Nature of the Study
This study is based on quantitative research methodology. Robson (2002, p. 6) mentions
"there are some circumstances where quantitative designs are preferred, and others where
flexible qualitative ones are more appropriate." This research has included a set of explanatory
variables based on HIS, operational characteristics, and internal and external factors of the
healthcare organization, and the healthcare quality as a dependent variable. The data variables
are operationalized with quantitative measures. Based on the proposed conceptual research
model, the study used descriptive and inferential multivariate statistical analysis and statistical
tests of hypotheses to observe the casual relationship between dependent variable and
explanatory independent variables. Hence, with such analytic methodology, quantitative analysis
with fixed research design is a suitable research methodology (Robson, 2002).
8/9/2019 Vinata_KulkarniPhD

13
In this study, a non-experimental longitudinal design with multivariate data was
examined over an extended time series. As longitudinal data on some of the variables was not
available, cross sectional multivariate data was used in those situations. The individual
community hospital was considered a unit of analysis. Annual data containing information about
the hospital characteristics, predefined quality measures, and the healthcare information systems
and technology programs were collected from authentic secondary data sources. According to
Robson (2002), advantages associated with secondary data are as follows. It is possible to tap
into extensive data sets, often drawn from large representative samples well beyond the resources
of an individual researcher. It is an unobtrusive measure in a sense that any individual researcher
who is using it does not affect such data collection. Miles and Huberman (1994) mentioned that
pragmatic operationalization of research requires economy, convenience, and interpretability of
results. As discussed by Robson (2002), the secondary data records are in a permanent form,
which facilitates reanalysis, reliability checks, and replication studies, and provides a low cost
form of longitudinal multivariate statistical data analysis. In view of these advantages of
secondary data, longitudinal quantitative secondary data from 1999 through the most recent
available time period was collected from the American Hospital Association (AHA) annual
survey of hospitals and The Dorenfest Integrated Healthcare Delivery System Database (IHDS).
Assumptions and Limitations
HIS is not the entire solution to tackling quality related issues of the healthcare industry.
This study concentrates on a limited focus of the healthcare quality through HIS to better
understand how EHR implementation with HIS can be one of the effective controlling and
driving factors to improve the healthcare quality. As per Stetson and Andrew (1996), focus of
8/9/2019 Vinata_KulkarniPhD
27/196
14
EHR is to improve the healthcare quality in terms of reducing the clinical processing time and
avoiding repetition of certain routine tasks, such as filling in the billing forms, writing
prescriptions, and requesting diagnostic studies. The healthcare literature indicates there are
several assumptions and characteristics of EHR, such as flexibility in information display format;
accessibility of information to the healthcare providers, administrators, and researchers; data
security; and authenticity in data access. Thus, this study has several assumptions including but
not limited to:
HIS-based healthcare quality evaluation is a comprehensive approach that includes not
only utilization of IS resources, financial indicators, and healthcare quality in terms of reduced
errors, increased safety measures, and cost reduction; but also should include patient satisfaction
of the services (Shortell, 2001). At present, EHR implementation is still in its developing stage at
macro level of the U.S. healthcare systems, and data to track EHR-related satisfaction of patients
and healthcare providers is not available to this writer. With widespread adoption of EHR
systems and robust HIS, her-related satisfaction of patients and healthcare providers should be
evaluated in future studies. Although this study used authentic data resources, such as AHA and
Dorenfest survey data, these data sets represent broad canvassing of only acute care hospitals,
chronic care facilities, and ambulatory practices on their adoption of and plans to adopt various
HIT components. The study did not include long-term care that should be considered for more
detailed analysis and conclusions in the future. Longitudinal data was not available for some of
the data variables described in this study. In those cases, the data analysis was based on cross
sectional data sets.

15
Although a conceptual model in the methodology section of this study has provided a
comprehensive healthcare quality model through critical success factors of EHR implementation;
data on few of the proposed critical success factors: (a) IS management of patients records, (b)
patients' awareness of EHR functionality, (c) remote patients' data access and management, (d)
prevention of clinical negligence and adverse events through HIS were not available at the time
of the study. Also, data on some predefined quality goals, namely- reduction in clinical data
errors, patient waiting time for the healthcare/clinical services and patient satisfaction of the
healthcare services, were not available to this writer at present.
Thus, data analysis has focused on the predictive influence of several critical success
factors as challenges impacting on the design and management of HIS with two proposed
measures of quality goals: cost effectiveness and HIPAA compliance. The research framework
acknowledges the existence of other challenges in view of the quality goals of an increase in
patient satisfaction and reduction in a patient waiting time for the healthcare and clinical
services. These challenges are beyond the scope of data analysis of this study; however, they are
reflected in the proposed conceptual model for completeness.
Overall, the estimators from the conceptual model did not provide predictions of what
will happen, but of what could happen by capturing dominant strategic IS management themes,
critical success factors of environmental determinants, organizational determinants, and
innovational determinants of the healthcare quality while implementing EHR.

CHAPTER 2. LITERATURE REVIEW
This chapter presents the literature review relevant to the U.S. healthcare system
background, the U.S. healthcare information systems (HIS), and implementation of EHR through
HIS for managed healthcare delivery and quality. Also reviewed are general theoretical
development and IS models in view of HIS integrity and quality and HIS modeling for the
healthcare quality while implementing EHR. Finally, conclusions of the literature review are
summarized. The discussion is built on several concepts presented in this author's unpublished
paper work at Capella University (Kulkarni, 2005a, 2005b, 2005c, 2005d) andon review of
published scholarly literature on HIS and the U.S. healthcare quality.
The U.S. Healthcare Systems Background
Before World War II, U.S. healthcare and health insurance was available through some
community institutions (Beach, 2005). During World War II, the main goal of the healthcare
plan was "to attract skilled workers that resulted in increased productivity and lots of corporate
loyalty"(Brailer & Von Horn, 1993, p. 126). The literature review indicates that since the 1970s,
instead of providing an attractive employee benefit, healthcare cost is continuously rising.
During the early 1980s, growing private industrialization and governmental concerns over rising
healthcare costs resulted in managed healthcare systems. A managed healthcare system is
defined as "Any system that manages healthcare delivery with the aim of controlling costs; these
systems typically rely on a primary care physician who acts as a gatekeeper through whom the
patient has to go to obtain other health services, such as specialty medical care, surgery, or
8/9/2019 Vinata_KulkarniPhD

18
physical therapy" (MedicineNet.com, n.d.). Since 1990, focus of managed healthcare is more on
operating procedures. The current healthcare infrastructure of the U.S. has significantly changed
to publicly provided healthcarecoverage, largely through Medicaid and Medicare, which may
have implications on total cost of the healthcare, and on the communication system between the
healthcare providers (doctors, nurses, healthcare administrators, and hospitals), and patients who
are in need of the healthcare.
Review of the U.S. Healthcare Information Systems (HIS)
Information technology (IT) has played a major role in the healthcare delivery. Use of
computers in the healthcare arena is dated back to the 1960s (Shortliffe, 2005). During the early
60s, leading IT companies such as International Business Machine Corporation (IBM), National
Cash Register Company (NCR), and Honeywell started offering healthcare application devices to
U.S. hospitals with a goal of improving healthcare and hospital productivity in terms of cost
effectiveness (Bekey & Schwartz, 1972). During the early 1970s, there was a small group of
hospitals that started adopting HIS (Hodge, Gostin & Jacobson, 1999). However, in the past, HIS
initiative was basically for automation of the business office and for the healthcare tools and
techniques related to diagnostic, therapeutic and surgical applications. During the 80s, with
innovations in database designs, HIS applications made some developments in planning and
administration of the healthcare data. During the same period, HIS also introduced low cost
financial systems for hospitals under 200 beds in size (Sneider, 1987). One of the goals of HIS
was to facilitate "the administration, processing of the centralized and distributed healthcare data,
and the development of effective system networking" (Mantas, 1992, p. 570). Over time, HIS
expanded to cover departments, clinics, and hospitals (Berger & Ciotti, 1993).

As healthcare organizations grew in size and complexity of operational procedures,
"corporate philosophy focused more on core businesses and outsourced other activities"
(Sandrick, 1994, p. 60). As new trends emerged in the healthcare industry, it became more
challenging to incorporate innovation and competition into the risk-adverse healthcare industry
(Teisberg et al., 1994). These researchers suggested four categories of measures of the medical
outcomes that are adopted by the healthcare industry, as follows. These four measures of the
medical outcomes can provide a guideline to the healthcare providers for assuring quality of the
healthcare services.
1. Clinical health is described as traditional biomedical and physiological health
status.
2. Functional health is described as quality of life and general well-being is
considered in view of the subjective evaluation by the patient of himself.
3. Healthcare satisfaction is described as consumers' attitude and responses to the
experience of seeking and receiving care.
4. Healthcare cost is related to acquiring the desired level of health outcome.
Davenport (1994, p. 120) presented parallel views in his "human centered IT approach,"
pointing to the fact that the focus of corporations shifted from hardware and software to how
"people in an organization acquire, share, and make use of the information." As per Davenport
(1994), the objective of human centered IT is to employ adequate methodologies to enhance
usage of the information. These arguments are quite applicable to adoption of HIS to support
collection, processing, and dissemination of the healthcare data. Boynton (1993) also suggested
strategic management of the information while building long-term process capabilities.

20
According to the literature review, since the mid 1980s, different hospitals used varied
systems from different vendors in their departments. However, in spite of increase in the HIS
costs, there was inadequate HIS interface and communication, and overall, HIS integration
became a major issue in the process of improving healthcare services (Sneider, 1987). Since
then, HIS has played an important role in the structure of the healthcare systems.
Several researchers have proposed frameworks with various perspectives to examine HIS
integrity. Based on the sample survey analysis of hospitals, Longo, Bohr, Miller, and Miller
(1990) concluded there was an increased need for the healthcare information data. Griffith,
Smith, and Wheeler (1994) demonstrated the evolution of strategic governance of IS in the
hospitals. MacLeod (1995) emphasized strategic management of the healthcare information
systems.As pointed byKongstvedt and Plocher (1995), the transition from fee-for-service to the
managed healthcare systems with a goal of cost minimization and quality improvement further
led to developments of an integrated HIS. Merlo and Freundl (1999) analyzed the factors
responsible for inefficient HIS in the healthcare organizations. These researchers concluded that
a lack of data integration is a barrier to the effective data analysis. Norrie and Blackwell (2000)
conducted a case-based study and concluded that a computerized patient data management
system can save administrative time and cost and can increase performance of the healthcare
organization. Ma (2003) analyzed the cross sectional sample survey data and reviewed HIS
applications on two dimensions, namely, basic functionality of HIS in administration and patient
care, and the global nature of the HIS application across and beyond the healthcare organization.
Based on his study, Ma (2003) concluded that HIS integrity is one of the driving factors of the
healthcare organization's performance.

Several IT developments evolved in the U.S. healthcare system through government,
professional, and research environments (Shortliffe, 2005).At present, the National Library of
Medicine (NLM), the National Center for Research Resources (NCRR), the Agency for
Healthcare Research and Quality (AHRQ), the American Medical Informatics Association
(AMIA), and the Healthcare Information and Management Systems Society (HIMSS), are some
leading agencies that are conducting research programs and making recommendations for
development of IT projects in the healthcare industry. Additionally, federal advisory groups such
as the National Committee on Vital and Health Statistics (NCVHS), National Research Council
(NRC), and the Institute of Medicine (IOM) are "educating the public, the health professions,
and policymakers regarding health IT topics" (Shortliffe, 2005, p. 27). He pointed out that
culture, the business case, and structural realities such as poor appreciation of IT as a strategic
asset; lack of structured knowledge and criteria in determining IS capabilities and
implementation processes; poor coordination; and a lack of generally accepted standards in
decision making regarding IT investment are the major barriers in successful implementation of
integrated HIS within the U.S. healthcare system (Shortliffe, 2005).
The literature review indicates an exponential increase in the use of the Internet during
the last decade, which made it possible to have easily accessible information on health
promotion, disease prevention, and disease management. Clinicians, politicians, and researchers
all have an increased recognizition of the inevitable role of IT in healthcare delivery. However,
as per Fadlalla and Wickramasinghe (2004, p. 65), along with cost reduction and quality
improvement, the U.S. healthcare industry is facing a challenge to meet a "stringent timeline to
become compliant with the health insurance portability and accountability act (HIPAA)
8/9/2019 Vinata_KulkarniPhD
35/196
22
regulatory requirements." These researchers emphasized a need for robust HIS so that the
"information that is captured, generated and disseminated by HIS can be of the highest possible
integrity and quality, as well as compliant with regulatory requirements" (p. 65). Medicare's
recent pay-for-performance initiative encourages improved quality of care through approaches
requiring forms of monitoring and data management. However, these approaches are difficult to
implement due to the current lack of robust health information systems (CMS, 2005).
Electronic Health Record through Healthcare Information Systems for
Managed Healthcare Delivery and Quality
The literature review indicates a need for effective IS implementation, not only with a
cost-centric approach, but also with a healthcare quality focus. Although HIS is not the only
avenue to addressing all the quality issues of the healthcare industry, it can be one of the
controlling and driving factors to improve healthcare delivery. Austin (1989) commented that
quality information is the result of quality information systems. Many researchers emphasized a
need for strategic HIS developments and evaluations prior to the selection of an operation model
and linking HIS to improvement in the organization's performance (Cerne, 1993; Halverson,
1996; Martin, 1996; Teisberg et al., 1994; Ummel, 1997). Austin and Boxerman (1997)
demonstrated some qualitative benefits of HIS in clinical and administrative applications. Prince
and Sullivan (2000) presented the conceptual framework for HIS integration and suggested
implementation of EHR at various medical services to enhance HIM capabilities. The U.S.
Department of Health and Human Services estimated about $140 billion annual savingabout
10% of total U.S. health spending through implementation of EHR-centric nationwide health
information network, resulting in improved healthcare and reduction in duplication of medical
8/9/2019 Vinata_KulkarniPhD
36/196
23
tests (Brailer, 2004).Thus, as pointed by the Institute of Medicine (2001), EHR could be one of
the potential key elements to improving healthcare quality through integrated and interoperable
healthcare information systems.
At present, when several healthcare practitioners treat a patient, they often do not have
complete information about their patient's illnesses or the medicines previously prescribed to the
patients.The IOM (2001) report mentioned that a majority of the clinical errors are not due to
carelessness of an individual, but due to errors in organization and management of the healthcare
systems. Independent studies have cited many situations of medical practices that do not meet
the required norms and result in healthcare errors that take several lives every year (Peirce,
2004). The research literature indicates that the healthcare and the non-health care organizations
are not different in maturity of quality management. As per Hartman, Fok, Fok, and Li (2002),
an increasing maturity in quality management appears to be related to at least some of the
changes in the information systems. HIS implicitly involves technology implications in the
organizational system.Technology has a potential to improve quality of the healthcare, safety,
effectiveness, patient-centered care, timeliness, and efficiency (Kohn, Corrigan, & Donaldson,
2000; Sokol & Molzen, 2002). Several healthcare studies indicated that archaic information
systems of the U.S. hospitals and clinics could have a negative effect on quality of patient care
(Swartz, 2004). Some of the reported causes of medical errors include "multiple physicians
treating the same patients without all having access to all the patients' medical records and with
each storing different, incomplete medical records in different places" (Swartz, 2004, p. 20).
Researchers have suggested integrated HIS for quality improvement in the healthcare
delivery. According to Swartz (2004), there is consensus among the healthcare industry experts
8/9/2019 Vinata_KulkarniPhD
37/196
24
that EHR based HIS would provide more coordination and higher quality of healthcare and
would reduce errors due to hand written prescriptions. Werder and Deng (1999) pointed that, in
the past, HIS were mostly proprietary solutions, acquired in separate modules and tightly
coupled through ad hoc means. Such HIS resulted into the stovepipe systems: each collected
patient-care data differently and many had duplicated large amounts of data and non-
interoperable functions. Today's HIS have to link together hospitals, clinics, physician offices,
and other business units that are mutually dependent, yet located at different places, each with
distinct business functions (Werder & Deng, 1999).
Today's HIS are quite complex and critical enterprise systems. As per the opinion of
Werder and Deng (1999), a transition from the earlier stovepipe systems to the next generation of
open HIS with interoperability and maintenance is a real challenge to healthcare information
management. Based on their case study, these researchers concluded that adoption of standard
architecture andinfrastructure is the best approach to achieve interoperable, extensible, and
cohesive HIS. While suggesting HIS reforms, Porter and Teisberg (2004) recommended the
collection and wide distribution of standardized healthcare information about individual diseases
and treatments that would facilitate patients to make informed choices about their care.
According to Porter and Teisberg (2004), setting up transparent billing and pricing mechanisms
by payers, providers, and health plans would reduce cost, confusion in data handling, inequality
in pricing, and other inefficiencies in the system.
Thus, the literature review indicates that effective IS development methodology and
supporting business processes with HIS architectural vision could be some of the key factors
while implementing EHR. Also, the literature suggests to evaluation of IT project in terms of
8/9/2019 Vinata_KulkarniPhD
38/196
25
associated costs, benefits, risks, and values. Researchers have described various approaches to
evaluate HIS and have constructed healthcare models based on different evaluation criteria of
decision making, durable products, financial benefits, and integration for optimal application of
IT in the healthcare industry, as well as using cost benefit analysis as evaluation tool (Maffei,
1997). The following section explores relevant theoretical background and conceptual models in
IT literature applicable to EHR implementation for healthcare quality improvement.
Theoretical Development and Information Systems Models for
Healthcare Information Systems Integrity and Quality
The information systems literature in general, and HIS literature in particular, contain
various organizational theories of performing HIS management and provide guidelines to
improve performance of the organization. The classical approach of the universalistic theories
focused on IS management and how it could be improved. However, as per Galliers and Leidner
(2003), the classical approach is narrow because it assumes that organizations have the same
structure, and the approach does not provide integrative perspectives of IS management.
According to the contingency theory, "organization design decisions are contingent (depend) on
environmental conditions" (Scott, 2003, p. 97). The contingency theory suggests the possibility
of alternative ways to organize and variation in the effectiveness of such alternative strategies;
and thus the theory provides an integrative strategic perspective of IS management (Galbraith,
1973).
Some researchers opposed the conventional contingency approach that considers
organizational environment as the determinant of its structure. Many researchers proposed a
strategic contingency theory that assumes several internal and external factors, such as
8/9/2019 Vinata_KulkarniPhD
39/196
26
organizational size, resources, managerial perspectives, technological developments and
adaptiveness, market and regulatory constraints during organizational decision-making, IS
planning, and its strategic management, to achieve goals of the organization (Miller, 1992; Scott,
2003;Van de Ven, 1986). Several IS researchers (Chan, Barclay & Copeland, 1997; Sabherwal &
Kirs, 1994; Sambamurthy & Zmud, 1992) supported such a strategic contingency theory
approach. These researchers empirically demonstrated that there is improvement in the
organizational performance through greater alignment and coordination between IS and business
units.
Young, Parker, and Charns (2001) examined the value of the contingency theory for
guiding empirical studies on healthcare provider integration. In the opinion of these researchers,
healthcare organizations should match their information processing capabilities with information
processing requirements in order to achieve optimal performance. Young et al. (2001, p. 77)
argued that the value of the "contingency theory depends on its ability to withstand rigorous
empirical testing." Young et al. (2001) pointed to the challenge to assess whether healthcare
providers have achieved optimal fit "between their organization's operating environment and
organization's internal design" (p.79). Thus, the Young et al. (2001) conclusions imply that,
unlike a manufacturing industry that generally has only one-dimensional performance indicators,
such as return-on-investment or profit margin, the current healthcare environment has multiple
performance measures of interest, including profit margin, operating costs, and various
healthcare quality criteria such as patient satisfaction and reduction in documented errors.
Many researchers emphasized the importance of information systems for healthcare
quality improvement (Griffith, 1994; Ummel, 1997). Through their survey based study, Bajwa,
8/9/2019 Vinata_KulkarniPhD
40/196
27
Rai, and Ramaprasad (1998) evaluated the associated structural factors of organizations and
concluded that executives in larger hospitals implemented HIS more than those in smaller
hospitals. Krohn and Broffman (1998) suggested integrated HIS for reliable financial and clinical
data. Killian (1999) demonstrated that healthcare organizations that have some system affiliation
often incline to adopt HIS. Ferrant, Lederer, Hall, and Krella (1998) conducted a survey based
study of HIS in seven community hospitals that shared patient healthcare information through a
common network. Through a questionnaire-based survey, these researchers collected and
analyzed data on perceived benefits of HIS in the views of physicians, medical record personnel,
and IS personnel. Ferrant et al. (1998) concluded that physicians' use of IS was quite low due to
less user friendly systems and due to doctors having inadequate time for handling such electronic
data. Also, conclusions of Ferrant et al. (1998) indicate that both physicians and IS personnel
considered use of electronic data as an essential technological requirement of the healthcare
services.
Lin and Wan (1999) conducted quantitative, cross sectional, secondary data analysis of
the structural design and performance of the top 100 integrated healthcare network services
(IHNS). The study concluded that IS integration indicates structural integration of the healthcare
organizations. Wan and Wang (2003) also examined the effects of integration on performance
ratings of the top 100 IHNS in the United States. The results of their cross-sectional data analysis
indicated high performance rated IHNS is related to more sophisticated HIS with managerial and
executive decision support systems. However, these researchers mentioned that clinical
integration is not yet well developed and needs to prove its efficiency. Wan and Wang (2003, p.
123) recommended use of "longitudinal data on the quality of healthcare network services and
8/9/2019 Vinata_KulkarniPhD
41/196
28
time varying data to serve as predictors of network performance" for further study. Later, Begun,
Kaissi, and Sweetland (2005) conducted an exploratory study through interviews of leaders in 20
healthcare organizations in the metropolitan areas of Minneapolis/St. Paul, MN, and San
Antonio, TX. These researchers showed that strategic planning is a common and valued function
in the healthcare organizations.
Young et al. (2001) pointed that most of the empirical studies of the contingency theory
performed cross-sectional data analysis and measured environmental uncertainty of the
organization. However, as per the opinion of Young et al. (2001), these empirical studies of the
contingency theory lack rigorous testing and they do not include a variable for measuring
information processing capabilities. Hence it is "important for the contingency theory to be
tested further and for the healthcare managers to participate in these research efforts" (p. 79).
Some researchers have conducted studies on the status of electronic health information
systems and their usage by healthcare providers. Kralewski, Hammons, and Dowd (2005)
conducted a sample survey analysis of medical group practices to assess their current use of
information technology and concluded there is inadequate use of IT in the healthcare systems.
Gans et al. (2005) concluded that at present, EHR adoption is significantly slow. These
researchers highlighted complexity and variation in the process of choosing and implementing
EHR and also pointed to a need for greater technological support to smaller healthcare practices.
Through an interview based survey, Weber (2005) conducted an exploratory study to present the
current state of electronic health information systems among perceptions of the U.S. physicians
in the 2005. Webers (2005) results indicate that less than 40 % of respondents mentioned usage
of EHR and identified cost as the major obstruction for EHR implementation. According to
8/9/2019 Vinata_KulkarniPhD
42/196
29
Weber (2005) results, the physicians believe that return on investment (ROI) through EHR is a
progressive benefit, which involves HIS project management with effective investment and
learning technology focus.
Miller and Sim (2004), in their exploratory study on physician's use of EHR technology,
commented that EHR has a potential to generate quality improvements in physician practices.
Kilo (2005), in his case based research study, explored aspects of the transformative changes
under way in an ambulatory care from the information technology perspective. The study
concluded that EHR as a knowledge-management tool is still in its development stage, which is
justifiable because the healthcare marketplace is not yet ready for such advanced products. Kilo
(2005, p. 1301) pointed that "funding sources--namely venture capitalists--are generally skeptical
of healthcare IT because of their adverse experiences in this sector in recent years". As per Kilo
(2005), while implementing EHR, it is essential to use the right technology in the right way so as
to improve healthcare quality. In his opinion, healthcare performance improvement efforts
require HIS intelligent system design through integration, connectivity, and the incorporation of
IT into the system.
Thus, while there is consensus amongst the researchers on IT as an enabling technology
for physician practices to pursue healthcare quality improvement, the research literature review
does not provide a specific solution to accelerate EHR adoption to advance healthcare quality.
However, in order to integrate and evaluate IS applications, researchers have proposed several
models based on the strategic contingency theory, as discussed in the following section.

Healthcare Information Systems and Electronic Health Record Modeling
With management perspectives for EHR implementation, healthcare information system
evaluation needs to establish the quantitative and qualitative benefits of IS to the healthcare
organization. According to Galliers & Leidner (2003), such HIS evaluation involves notions of
costs, benefits, risks, and values, and it involves organizational processes to assess these factors.
Information economics models can provide one of the approaches to evaluate both quantitative
and qualitative benefits of EHR implementation to the healthcare industry, as discussed below.
Information Economics Model
Parker, Benson, and Trainor (1988)proposed a broader concept of the effect of IT
investment on business performance of the organization. The model considers traditional cost
benefit analysis through four lenses of ROI. This approach could be applicable to assess the ROI
of EHR by considering the traditional cost-benefit analysis, along with a certain set of predefined
qualitative measures of EHR, such as patient data linking, reduction in patient's data processing
time, and documented errors .The approach is useful to assess how equipped the healthcare
industry organization is to implement EHR in view of new technological challenges and required
skills. The model seems quite adaptable to an organization's HIS framework and circumstances
and can enhance cost-benefit analysis through business and technology domain assessments
(Galliers & Leidner, 2003). The model can be evaluated through established goals of connecting
EHR directly to the patient care provision, such as providing, consuming, managing, reviewing,
and reimbursing for patient care services. Such assessment of business value of IS processes in
the Parker et al. (1988) information economics model involves top level management. However,
the model does not focus much on users of IS at lower levels during assessment of the process
8/9/2019 Vinata_KulkarniPhD
44/196
31
(Galliers & Leidner, 2003).Goldsteins (1995) generic integrated model provides comparatively
more comprehensive ROI perspectives. Goldsteins (1995) model identifies causes of lower
quality performance and accordingly conducts effective quality improvement interventions to
eliminate those shortcomings.
Generic Integrated Model
Goldstein (1995) suggested three main targets of intervention: "The health professional,
the patient, and the health service delivery system and further suggested even the combinations
of these targets" (p. 55). The generic integration model has the widest perspective of modeling,
i.e., clinical practices, value evaluations and organizational studies. As per Goldstein (1995), the
focus of the generic integration model is to develop evolutionary structures and processes. This
approach allows "physicians and managers to learn to share information and clinical
perspectives, and to set financially directed performance criteria" (p. 56). Goldstein (1995)
formulated an 11 block and 4 level model based on his theory of high quality of healthcare
administered by an error free healthcare delivery system, as described in the Figure 1.
As described by Goldstein (1995), level one (L1) contains the fundamental blocks of any
healthcare system. In this model, a physician's decisions account for almost 80% of healthcare
costs. Primary care networks are primary care providers. The IS management is responsible for
collecting dispersed clinical data. Reengineering and continuous quality improvement (CQI) of
care are enablers of an efficient and comparatively less costly delivery system. Also, according
to the model, continuum of care requires effective coordination within the system modules.
Level two (L2) identifies blocks that improve access and quality of the delivered care. Level
three (L3) blocks support the patient and the provider, while level four (L4) is "the empowering
8/9/2019 Vinata_KulkarniPhD
45/196
32
of the people responsible for restructuring the healthcare system" (p. 62). Thus Goldstein (1995)
model encompasses structural, technical and managerial issues of the healthcare organization
that can be used as a framework for useful collaborative systems while implementing EHR. The
model emphasizes leadership of healthcare managers and providers for transformation of the
healthcare delivery to function in a proactive manner and involvement of users at various levels,
while controlling cost and improving healthcare quality. As pointed by Maffei (1997), the
generic integrated model suggests major enhancement and collaboration of existing healthcare
information systems and healthcare information management.
Linking the HIS Integrity Model with Consolidated BSC & CSF Analysis
While the information economics model goes beyond costbenefit to value, Goldsteins
(1995) generic integrated model provides a wider perspective by linking HIS evaluation across
various stages of the healthcare delivery system in view of internal and external components of
the organization. As per the opinion of Ward and Peppard (2002), for a successful IT project in
general and EHR implementation in particular, it is essential to understand the current HIS
processes that are in place. Maffei (1997) argued that these HIS processes include several
interlinked activities that involve patients, as well as the roles of those who deliver healthcare,
such as doctors, nurses, pharmacy, laboratory, and healthcare administrators. According to
Maffei (1997), evaluation of an integrated HIS model requires fact-finding, analysis, and
interpretations. According to a GAO Report (2004), with an expected increase in the U.S.
healthcare spending in the subsequent decade, and with important stakes such as encouraging
high-quality clinical services while implementing EHR, the healthcare organizations need to
improve accountability. In this sense, unless healthcare delivery system performance indicators
8/9/2019 Vinata_KulkarniPhD
46/196
33
are linked to the drivers of EHR effectiveness in a meaningful way, desired improvements in
healthcare quality are unlikely to occur.
Thus, as described by Ward and Peppard (2002), the real challenge for the healthcare
organizations while implementing EHR is to create meaningful systems for strategic
organizational assessment and then use that information in internal policy and strategic decision-
making. The challenge can be achieved by the critical success factors analysis that has its roots
nearly 40 years back. The critical success factors analysis is a cumulative research approach
about decision-making, IS planning, and identifying the organization's important performance
objectives (Cleland & King, 1968; Zani, 1970). In their study, Baker and Pink (1997),
Castaneda-Mendez, Mangan, and Lavery (1998) pointed the relevance of the balanced score card
(BSC) and critical success factors (CSF) analysis to the healthcare organizations. These
researchers suggested BSC and CSF analysis to link healthcare practices with outcome, value,
and cost of the healthcare services and related projects. Thus, while Goldsteins (1995) model is
a collaborative framework of structural, technical, and managerial issues of the healthcare
organization systems, consolidated balanced scorecard and identification and analysis of the
critical success factors of the generic integrated healthcare system could provide a
comprehensive integrated view of EHR project in view of healthcare quality performance as
discussed below.
Consolidated Balanced Scorecard and Critical Success Factors Analysis
Kaplan and Norton (1992) introduced the balanced scorecard (BSC) as a set of measures
used to facilitate a holistic, integrated view of the business performance. Initially, Kaplan &
Norton (1996, p. 75) created the scorecard to supplement "the traditional financial measures with
8/9/2019 Vinata_KulkarniPhD
47/196
34
the criteria that measured performance from additional perspectives such as those of customers,
internal business processes, and learning and growth. Later, organizations developed BSC as a
strategic management system linking organizational long-term strategy to its short-term goals. In
view of the limitation of financial measures to display only past decisions, BSC emphasizes
identification of a certain balanced set of objectives and measures for managing the performance
of an organization or the industry. As per Ward and Peppard (2002, p. 208), the BSC approach
can provide a structured methodology for "monitoring current performance of the healthcare
industry/organization with four perspectives of finance, patient satisfaction and quality issues,
internal business, and innovative and learning perspectives." This approach suggests identifying
objectives for each of these perspectives and assigning relevant measures to these objectives as
"key performance indicators"(p. 208). Thus, the BSC approach can provide information needed
to measure the performance of healthcare business process results, as well as to improve the
processes and to motivate and educate the healthcare employees.
According to Ward and Peppard (2002), CSF analysis is helpful in identifying critical
factors in achieving the objectives set by BSC. The technique involves identifying structural,
managerial needs and performing strengths, weaknesses, opportunities and threats (SWOT)
analysis of existing systems against CSF in view of each objective. The consolidated BSC and
CSF technique supports the economic value model and provides a rigorous assessment of
"prioritized" IS opportunities, given the "current business strategy" (Ward & Peppard, 2002, p.
213).
Thus, Goldsteins (1995) HIS integrity model supplemented with consolidated BSC and
CSF analysis can provide a conceptual framework for EHR implementation. The approach can
8/9/2019 Vinata_KulkarniPhD
48/196
35
provide a comprehensive understanding of current performance of the organization (Ward &
Peppard, 2002). The technique can be applied to examine the healthcare organizations in the U.S.
healthcare industry (p. 213). The approach can assist in prioritizing healthcare activities, HIS
requirements, and evaluation of predefined variables of healthcare quality, such as reduction in
medical and medication errors, time and cost factors, meeting the regulations' requirement, and
improvement in patient safety. Therefore, using the balanced scorecard, healthcare organization
can construct a scorecard of objectives and associated measures for the previously described four
perspectives of finance, patient satisfaction and quality issues, internal business, and innovative
and learning perspectives of the organization. The literature review indicates use of such a BSC
approach to evaluate hospital performance.
During the 1998 system-wide report on Ontario, Canada, hospitals, researchers adapted
the BSC approach and provided information on the performance of Ontario's acute care hospitals
(Pink et al., 2001). Later, during 1999, the same team of researchers utilized BSC to extend the
information on the performance of Ontario's acute care hospitals at two levels, namely at
aggregate and subgroups of small, community, and teaching hospitals (Pink et al., 2001). These
researchers developed indicators of Canadian hospitals' healthcare performance in four areas:
system integration and change, financial conditions, patients' satisfaction, and clinical
deployment and outcomes. Such a BSC and CSF approach can be extended and adopted to
evaluate the U.S. hospitals' healthcare performance by analyzing the relationships among EHR
related HIS integration, as well as healthcare quality in terms of financial indicators, clinical
outcomes, and patient security and privacy issues. As pointed by Zelman, Pink, and Matthias
(2003), the consolidated BSC and CSF approach in healthcare is in its growth stage. Hence it is

essential to have appropriate modifications in the approach to reflect the U.S. healthcare
organization's perspectives that include healthcare quality goals with some predefined measures
of healthcare quality.
Summary of the Literature Review
The literature review explored historical developments of healthcare information systems
and identified several methodological problems and approaches in current HIS management. At
present, hospitals are motivated by a need to increase healthcare quality through reduction in
medical and medication errors and cost, improvement in patient safety, and creation of effective
IS processes. Healthcare organizations are looking at and drawing from quality management
processes used by manufacturers and other industries, such as the International Organization for
Standardization (ISO) 9000 series quality management systems standards, six sigma rigorous
data driven processes, and failure mode effect analysis: a systematic way to identify and prevent
product and process problems before they occur (Rossow & Grimes, 2003; Swan & Boruch,
2004).
While there exist several IT/IS press articles on EHR implementation and healthcare
quality through HIS that are accessible through the Internet, at present, academic research in this
area seems quite limited. For example, for 1995-2005, Google search engine returned 4,710,000
hits for information systems and healthcare quality, of which 920 hits for information systems,
healthcare quality, and EHR. However, for 1995-2005, the academic search through Business
Source Premier search engine returned only 84 research articles on information systems and
healthcare quality; of these hits, 21 are academic. There were 644 hits on EHR, of which 87are
academic papers and fewer than 15 are academic articles on EHR that focus on healthcare

quality. Thus, in the opinion of this writer, a very limited number of empirical studies on HIS
and EHR implementation for healthcare quality have been conducted. Some of the academic
studies were exploratory and descriptive in nature andwere case based studies or adopted cross-
sectional data analysis. These studies lack comparability and generalizability of the results and
derived conclusions.
So far, most academic literature for EHR implementation and healthcare quality in the
HIS literature seems discrete in nature, and hence, difficult to quantify and research. With regard
to the strategic contingency theory approach, a healthcare organization needs to bring strategy,
structure, and context into natural alignment while building unique solutions to the problems
(Miller, 1987; Mintzberg, 1991). This requires building a comprehensive conceptual framework
and evaluating HIS projects of EHR implementation in view of the predefined healthcare quality
goals. The generic integrated model with a foundation of the strategic contingency theory and
evaluation tool of consolidated BSC and CSF analysis for quality performance of healthcare
industry was the basis of construction of EHR-centric conceptual model in this study. Emphasis
of the conceptual model was on the integrative analysis for predefined set of healthcare quality
goals by looking at critical success factors as drivers of successful EHR implementation at both
methodology and process level, which involved healthcare providers, HIS integrity, and
associated internal and external factors of the healthcare organization.

CHAPTER 3. METHODOLOGY
The two research questions described in Chapter 1 are:
1. How can cost effective and value added healthcare quality be achieved through
strategic healthcare information management (HIM) while implementing EHR?
2. What are the critical success factors for healthcare quality while implementing EHR?
To address these two research questions, a conceptual model is presented in this study. The
model is based on the strategic contingency theory, Goldsteins (1995) integrated healthcare
systems model, and the consolidated balanced scorecard and critical success factors analysis
approaches. Quantitative methods are suggested to examine the critical success factors in terms
of HIS integrity, environmental factors, basic functionalities, operational characteristics, and
innovation and learning perspectives of the healthcare organization for healthcare quality
improvement during EHR implementation. The proposed model, data sources, measurement of
data variables, and statistical methods to test the hypotheses are presented.
In view of to the two research questions described above, the research objectives of this
study were to: (a) Perform an exploratory research into a series of proposed relationships
between organizational internal and external factors considering the two important systems for
successful EHR implementation and enhancing healthcare organizations; namely, healthcare
information systems (HIS) and healthcare quality. (b) Identify the critical success factors (CSF)
and quantify the perceived importance of each CSF during EHR implementation for the
healthcare quality goals. (c) Construct a regression analysis based predictive model using the

proposed critical success factors for healthcare quality improvement during EHR
implementation, and compare and contrast the results of (a), (b) and (c) for small, medium, and
large size healthcare organizations to better understand how critical success factors and EHR
implementation decisions vary with size of the healthcare organization.
Research Design with the Conceptual Model
With a foundation of the strategic contingency theory, the generic integrated model
(Goldstein, 1995), and an evaluation tool of consolidated BSC and CSF analysis, the EHR
centric conceptual model is developed in this study to achieve healthcare quality goals. The
approach attempted to make a theoretical case to extend CSF to facilitate HIS planning in view
of the relationships between organization's internal and external attributes and goals. The model
considered healthcare organizations' context, structure and quality variable. Goldstein (2001)
explained the four fundamental blocks of the healthcare system as follows. Physicians decisions
account for almost 80% of healthcare costs. Primary healthcare providers constitute the primary
care network in the healthcare system. IS management is responsible for collecting dispersed
clinical data. Finally, reengineering and CQI of care is essential for a cost effective, efficient
healthcare delivery system. Adapting and restructuring these fundamental blocks of the
healthcare system of the Goldstein (1995) model, an EHR centric conceptual model for
healthcare quality is derived as follows.
In view of the level one building blocks of the healthcare systems in the Goldstein (1995)
model, in the conceptual model, physician's responses to HIS systems and technology represent
the physician's decisions block of the Goldstein (1995) model. Such approach during EHR
implementation would facilitate timely information and retrieval of specific information,

particularly daily operational information for monitoring the organizational performance
(Galliers & Leidner, 2003; Huber & MacDaniel, 1986).
To represent the level one primary care network block of the Goldstein (1995) model, the
conceptual model used the healthcare organization's environmental factors and basic
functionality such as hospital bed size, healthcare facilities' affiliation status, managed healthcare
status, and HIS structural functionality. This approach supports Scotts (2003) suggestions to
consider the contingent control variables that relate toan organization's environment, mission,
technology, firm, and industry variables.
In view of the EHR mission of management of patients' record, the conceptual model
used EHR related structural functionality and connectivity of HIS with effective database
management of patients electronic records to represent the level one IS management block of
Goldstein (1995) model. According to Galliers and Leidner (2003), HIS management around the
healthcare business processes allows greater focus on the goals of the healthcare organization,
rather than just operationalizing organization's objectives around existing activities. Also,
researchers (Wickramasinghe, 2000; Wickramasinghe & Mills, 2001), suggested that HIS
management around the healthcare business processes can effectively link the key players within
the basic EHR system to facilitate patient information data management properly, with a cost
effective value added outcomes. To represent the building block of reengineering and CQI of
care of Goldsteins (1995) model,the conceptual model used strategic application of HIS with
learning perspectives, responses to new IT tools, and the executive decision support
functionality. Such approach considered process reengineering strategies, change, and quality
management, which is essential to build flexible systems and continuous improvement of

41
management processes while adapting dynamic software technology and medicine. The
approach supports Lams (1995) views that "process reengineering requires characteristics of a
learning organization that has continuous capacity to adapt and change" (Kulkarni, 2005a, p. 30).
Also, the Continuum of care Network is the level-one building block of the Goldstein (1995)
model, which requires effective coordination within system modules. Hence, the conceptual
model represented this building block in terms of HIS connectivity aspect of facilitation of
communication and coordination.
Level two building blocks of healthcare systems in the Goldstein (1995) model are to
improve access and quality of the delivered care. Fadlalla and Wickramasinghe (2004) suggest
that new technologies and techniques in the healthcare organization could be driving forces of
cost effective healthcare quality. Hence, the conceptual model represented this building block in
terms of supplementary technology applications and EHR supporting systems, applications of
patient safety and data security tools, and remote patient data access and management.
Level three building blocks of healthcare systems in the Goldstein (1995) model support
patients and healthcare providers. As per IOM (2001), high quality healthcare initiative involves
patient centered healthcare services that are responsive to patient preferences, needs and safety.
Hence, the conceptual model considered the level three building blocks of Goldsteins (1995)
model in terms of patients' awareness to EHR functionality and applications to reduce clinical
negligence and adverse events. Finally, the level four building
