Surveillance Outside the Hospital: Monitoring Home
Health Outcomes
Regina Nailon RN, PhDClinical Nurse Researcher
The Nebraska Medical Center
State of the Art ConferenceApril 22, 2013
Portions of this work were supported in part by a grant from the Cardinal Health
Foundation.
Session Objectives
• Explain the role of outcomes data in the current health care delivery system.
• Review a case study demonstrating how to achieve measurement of outcomes in outpatient settings.
Partnering Agencies• Alegent Creighton Health at Home• Children’s Home Healthcare/Children’s Hospital &
Medical Center• Home Nursing with Heart• InfuScience, a Bioscrip Company• Methodist Home Health and Hospice• Visiting Nurse Association of the Midlands• The Nebraska Medical Center
– Nursing Research & Quality Outcomes Department– Peggy C. Cowdery Patient Treatment Center
• University of Nebraska Medical Center– Department of Infection Control and Healthcare Epidemiology
Increased emphasis
on reducing hospital
LOS
Increase in patient care
in out patient and
home health
settings
Increased incidence of
patients discharged
from hospital
with CVC in place
Lack of research
examining standardize
d maintenance care and
its association with CVC outcomes
Preventive measures
have largely concentrated
on CVC insertion or the use of
technologic improvements
Significance of CLABSI
• 78,000 central line-associated bloodstream infections are estimated to occur yearly In United States hospitals and dialysis units
1.
• CLABSI are associated with an estimated mortality rate of 12.3%
2 and excess healthcare
costs between $7,288 and $29,156 per episode

CVC Adverse Eventsin Out of Hospital Settings
• CLABSI rates in home settings range from 0.771 to 6.72 per 1,000 central line days.
• Thrombosis rates range from 0.063 to 1.354 per 1,000 central line days in pediatric and adolescent populations, as high as 9.3 in adults5.

HAI Prevention Outside Hospital
• Healthy People 2020– Prevent, reduce, and ultimately eliminate healthcare-
associated infections (HAIs)• Focuses on acute care, surgical centers, outpatient clinics
• National Action Plan to Prevent HAI: Roadmap to Elimination, 2009
1
– Phase II (Draft April, 2012) extends to ASC, outpatient dialysis
– Phase III (Draft July, 2012) extends to long term care1. Department of Health and Human Services, rev. 2012
Ambulatory Care HAI Prevention Aims
1
• Proactive HAI prevention at the clinic level• Increase education and training in HAI prevention
for providers, as well as patients and families• Sustain and expand improvements in oversight and
monitoring• Develop meaningful HAI surveillance and reporting
procedures

"Measurement is the first step that leads to control and eventually to improvement. If you can't measure something, you can't understand it. If you can't understand it, you can't control it. If you can't control it, you can't improve it."
- H. James Harrington
Central Venous Catheter Use Outside the Hospital
• Deficiencies with tracking patients who leave hospital with CVC
• No national surveillance mechanism to monitor CVC-related outcomes in home health or non-acute long term care
“Whenever you can, count.”

Standardizing Central Venous Catheter Care in the Outpatient
Realm: Care from Hospital to Home
(SCORCH)
SCORCH Surveillance System
• Engage stakeholders• Describe system• Gather evidence of system’s performance• Lessons learned – ensure use of findings• Conclusions/recommendations
CDC. Updated guidelines for evaluating public health surveillance systems: Recommendations from the guidelines working group . MMWR 2001; 50 (RR13); 1-35.
Engaging Stakeholders• Six Omaha area home health/home infusion
agencies– Consensus building sessions May-November, 2011
• Developed guidelines to standardize CVC care– National Guidelines Clearinghouse
– The Nebraska Medical Center website: http://www.nebraskamed.com/central-line-care
– Surveillance data• Monthly since January 2012• 2011 data to serve as baseline• June 2012 revised data
– More granular analyses
“A public health surveillance system can…be useful if it helps to determine that an adverse health-related event previously thought to be unimportant is actually important” (CDC, 2001).
Public Health Importance of Surveillance System
• Delayed treatment• Costs• Hospital admissions/readmissions• Preventability
– Standardizing care in out of hospital settings

Evaluating SCORCH Surveillance System
• Data elements refined after Q1 2012 reports– Events tracked by CVC device type and # lumens– Clarified data for patients receiving agency RN care– Ratio of occlusions to fibrinolytic doses given
» Were non-occluded lumens being treated?
– Consensus that all use CDC BSI definition» Communication gaps in knowing BSI occurred
• Generated list of patient-centered research ideas

“Surveillance for outcome measures in ambulatory care settings is challenging because patient encounters may be brief or sporadic and evaluation and treatment of consequent infections may involve different healthcare settings (e.g., hospitals)”
CDC. Guide to Infection Prevention for Outpatient Settings: Minimum Expectations for Safe Care, 2012, p. 7.
Conclusions and Recommendations
• Home health outcomes are measurable– Develop system of data validation
• Lab data• Claims data• Communication system from receiving hospital to HHA
when CLABSI present on admit
• Focus in on specifics of CVC care to better drive QI– Agency use of reports
• Continue monitoring use of standardized care guidelines
“When you are face to face
with a difficulty,
you are up against
a discovery.”
- Lord Kelvin, British physicist
Next Steps
• Extramural funding – Refine/further develop surveillance system
» BSI rate/1,000 device days by device type» Patient demographics
– Capture in real time hospital admissions/ readmissions attributed to BSI
• Close loop/communicate BSI to HHA/HIA
Next Steps
• Patient-centered outcomes research
• Collaborate with 3rd party payer, HHA/HIA, ambulatory/outpatient clinic providers
• Infection control practices• Reporting structures• Clinician CVC-related behaviors/competencies
Next Steps
• Complete production of patient education DVD aimed at empowering patients to understand what CVC care should look like
• Complete patient-focused study, “Day in the Life of a Line”– 14-day diary of who/when/where/why CVC care is
being provided
Next Steps
• Extend surveillance to long term care settings– CLABSI– CAUTI
• Admissions / readmissions• Standardize urinary catheter care
