Technology Assessment

The process that examines the available evidence to form a conclusion as to the merits or role of a particular technology in relation to its possible use, purchase or reimbursement in current medical practice. Examines the safety, effectiveness, efficiency and

appropriateness Includes medical devices, procedures and standards, and

pharmaceuticals To maximize quality: the most effective health care

service that science can provide Can we afford it?

Page 3: Technology and Health Care HCA 701 November 10, 2005

Categories of Technology

Devices - "the quiet heroes of health-care innovation" Diagnostic devices (MRI, CAT, SPECT, etc.) Treatment devices

Medical and surgical procedures (examples): Radial keratotomy used to improve vision. Genetic testing Treatment head injuries, cancers, joint replacements, etc.

Pharmaceuticals Efficient and appropriate uses for FDA approved drugs Labeling – language used to delineate the clinical use of a

drug (indications, dosage, adverse effects, etc.). Understanding the long-term affects of uses of some drugs, Understanding alternative uses for drugs (e.g., manoxodil)

Page 4: Technology and Health Care HCA 701 November 10, 2005

Technology Life Cycle

Investigation – laboratory and clinical studies to discover or create, refine and package a new diagnostic or treatment modality.

Promotion – introducing the technology into the buying community.

Acceptance and utilization – incorporating the technology into practice.

Decline – as technology is supplanted by superior new technology.

Obsolesce – when the new technology is obsolete and no longer appropriate.

Targeting Technologies for Assessment Improve individual patient outcome Positively affect a large population Reduce treatment costs Reduce unexplained treatment variation.

Page 6: Technology and Health Care HCA 701 November 10, 2005

Three Components of Technology Assessment High Utilization

Rapidly increase uses of a technology may signal inappropriate or excessive utilization. (e.g., Cesarean births rates)

Uses of high technology for common conditions may be inappropriate

E.g., use of mammography for women under the age of 50 has sparked controversy on the practice of high technology.

Potential for Harm Requires different standards and assessment priorities for

different risk factors in patients. High Cost – willingness of payers to pay form some

technological procedures or diagnoses.

Page 7: Technology and Health Care HCA 701 November 10, 2005

Performing Technology Assessment Scientific assessment: does it work? Clinical assessment: does it work better than

something that already exists? Economic assessment: Cost (use of Cost

benefit analysis). Social or societal issues:

will providers use it? Will patients use it? Are secondary benefits more detrimental than

primary benefits?

Page 8: Technology and Health Care HCA 701 November 10, 2005

Problems in Performing Technology Assessment Lack of Evidence (not enough literature or patients to

study, or poorly conducted research) Lack of Agreement on How to Perform the Assessment

(may lead to different results using different techniques) Inconsistent Evidence (may result from different or

inconsistent research methods) Legal Interference (can be influenced from biased

resources) Breadth of Topics (difficult to successfully study or

assess all technologies) New Information (assessment process must be ongoing

to adequately compare new uses)

The Impact of Pharmaceuticals on Health Care Prescription drugs account for more than 15% of

health care spending ($162 billion) Faster growth than all other segments of health

care Prescription drug coverage over the last 10

years has been a catalyst for growth Primarily a large multinational corporate

enterprise 10 largest pharmaceutical companies accounted for

60% of all Rx sales in U.S. in 2004

Using Outcomes and other Assessment Tools to Improve Quality

Quality Improvement

Page 16: Technology and Health Care HCA 701 November 10, 2005

Consider quality as a major priority over cost, choice or doctor, or range of service

Sources for information comes from family and friends

Concerned about the physician’s skills, but place increasing emphasis on communication skills, care attitude and certification

How Individuals Determine Quality

Page 17: Technology and Health Care HCA 701 November 10, 2005

The degree to which health services for individuals increases the likelihood of desired outcomes and are consistent with professional practices (IOM, 1990)

Quality Defined

Page 18: Technology and Health Care HCA 701 November 10, 2005

The Debate on Variation of Care

Influenced the quality pursuit Variations to care can be found between

regions, between hospitals, and between physicians within hospitals

Typically a result of clinical decisions made based on individual physician’s experience and training

If you cannot measure quality, you cannot improve it

Applying the best in current knowledge and technology to a personal health problem

Outcomes compared for effectiveness Based on future expectations

Technical Performance

Page 22: Technology and Health Care HCA 701 November 10, 2005

Care that meets individual and social expectations and standards

Patients communication of symptoms to the clinician

Clinician communication of options to the patient

Interpersonal Performance

Page 23: Technology and Health Care HCA 701 November 10, 2005

Organizations that measure performance Joint Commission on Accreditation of Healthcare Organizations

(JCAHO) Non-profit organization that surveys and rates health care organizations and sets

standards for care Voluntary organization for hospitals but usually essential in qualifying for

reimbursement National Committee for Quality Assurance (NCQA)

Uses HEDIS - standardized performance measures designed provide purchasers and consumers with information compare the performance of managed health care plans and their providers (Physician “report cards”)

Institute of Medicine Provides scientifically informed analysis outside government realm to improve

health Agency for Healthcare Research and Quality (AHRQ) (HHS)

Practice Guidelines

Once referred to as “Cookbook Medicine” Intended to influence the direction of patient

care Systematically developed statements to assist

practitioner decisions about the appropriateness of care

Intended to decrease variations of care Criticized that de-emphasizes the “art” of care Prefers the use of “evidence based care”
