What factors are contributed to the emergence of outcomes research?

1 the need for cost containment in the health care sector, 2 the need to examine outcomes other than mortality, such as health-related quality of life, 3 the need to determine "best practices" and reduce the great variation in health care that occur


What is the purpose of outcomes research?

efficacy and effectiveness


How is efficacy defined?

as the effect of treatment delivered under carefully controlled conditions; "does it work? is it safe?"


How is effectiveness defined?

as the usefulness of a particular treatment to the individuals receiving it under typical clinical conditions


What are some of the frameworks for outcomes research?

the Nagi model (disablement model), the International Classification of Impairments, Disabilities, and Handicaps, the International Classification of Functioning, Disability, and Health


What does the Nagi model describe?

active pathology, impairment, functional limitation, and disability


What does the International Classification of Impairments, Disabilities, and Handicaps describe?

the long-term abnormality of disease as impairments, disabilities, and handicaps


What does the International Classification of Functioning, Disability, and Health describe?

changes in body functions or structures, activities, participation and disability


What are the different measurement tools for outcomes research?

self-assessment and quality of life


What issues need to be considered when developing a self-assessment tool?

1 construct definition, 2 target population and 3 anticipated use of the scale; must meet criteria for validity


How is quality of life defined?

a global concept that can include elements as diverse as perceptions of health, satisfaction with the work environment, quality of family and social relationships, satisfaction with schools and neighborhoods, productive use of leisure time, etc


How is health-related quality of life measured?

measures of HRQL should include elements related to physical, psychological, and social functioning

medical records, abstracts of medical records, insurance claims databases, in-house databases, natinoal outcomes databases


What are some of the advantages to medical records?

they contain a great deal of information that can be evaluated in context


What are some of the disadvantages to medical records?

reviewing is time-consuming, information may be inconsistent and incomplete


What are some of the advantages of using abstracts of medical records?

time efficient


What are some of the disadvantages of abstracts of medical records?

may be errors in coding the information, including diagnoses, comorbidities, and complications; information is often less specific than desired


What are some of the advantages to the use of insurance claims databases?

tend to be complete because of their link to reimbursement for services, offer access to large numbers of patients at low cost


What are some of the disadvantages of insurance claims databases?

limitations on the number of diagnoses, comorbidities, and procedures that are listed; coding strategies may change with policy changes that may not be a change in practice; person-level changes generally not available


What are some of the analysis issues on outcomes research?

case mix adjustments, missing data, survival analysis, and comparisons across scales
