◦Research methods have been developed to appraise, describe, and compare the relative value of health services. These are called…
cost-effectiveness analyses or economic evaluations
Economic evaluations are distinct from clinical evaluations in that they..
focus on costs and outcomes rather than the efficacy or effectiveness of a specific intervention.
Descriptive profile of the costs and outcomes of one or more interventions.
Cost-consequences
Identifies the least costly alternative for services that result in equivalent outcomes.
Cost-minimization
Describes and compares the relative costs and outcomes of two or more interventions that result in the same type of outcome.
Cost-effectiveness
Describes and compares the relative costs and outcomes of two or more interventions in which the outcomes of interest include health status and the value of the status to the individual.
Cost-utility
Describes and compares the relative costs and outcomes of two or more interventions in which both the costs and outcome can be measured in monetary values.

Conducting Economic Evaluations
Research question defines the purpose and scope of assessment.
◦Descriptive analysis or comparative assessment.
◦Important to consider the perspective of the analysis (from society, payers, providers, and/or consumers).
◦Evaluators of economic analyses should make judgments regarding the internal and external validity of their assessments including source of bias, contamination, and noncompliance.
◦When critically analyzing economic analyses, it is important to look at both internal and external factors
Questions to ask with internal validity
Did the research question clearly/accurately define compared options? Was perspective of the analysis defined?
–Were the important costs and outcomes identified and properly measured and valued?
–How rigorous was the methodology used to establish costs and the effectiveness of service alternatives?
–Were differences between outcomes analyzed and compared?
Questions to ask with external validity
Are the outcomes worth the costs?
–Could my clients expect similar health outcomes?
–Could I expect similar costs?
Locating Economic Evaluations
Research can be found with traditional databases like MEDLINE and HealthSTAR.
◦National Health Service Centre for Reviews and Dissemination (University of York, UK) contains structured abstracts and critical appraisals of economic evaluations from 1994 (Web-based).
◦Health Economic Evaluations Database contains abstracts and structured reviews from 1967 (subscription).
There are five different types of economic evaluation that have been defined in the literature:
1.Cost-consequences
2.Cost-minimization
3.Cost-effectiveness
4.Cost-utility
5.Cost-benefit analyses
In order to inform consumers and clients about the relative value of specific health and rehabilitation services for defined clientele, we must:
1.Conduct evaluations to determine whether specific interventions are effective at attaining desirable outcomes
2.Evaluate effective interventions to ensure that they offer the most efficient means of attaining specific outcomes
3.Effectively communicate these results
The intent and purpose of economic evaluations are to
provide clients and consumers with information regarding value in order to inform their decisions.
Within the health care context, the term value refers to
the relative worth, utility, or importance of a service in meeting the health needs of a defined clientele
For a service to be “valuable,” clients should…
receive a fair return (i.e., service and outcome) for something exchanged (i.e., finances and time invested)
