| Annotation | Public-use datasets can extend data collected by individual investigators in various ways: making external comparisons, providing additional data on individual respondents, and creating internal comparison groups. The authors describe the advantages and limitations of these methods and practical and conceptual issues in combining investigator-initiated and public-use datasets. These issues are illustrated with a study of functional decline in 674 patients following hospital admission for hip fracture, augmented with a data from a public-use dataset, the Established Populations for Epidemiologic Studies of the Elderly (EPESE). The results showed that by creating an internal comparison group of EPESE respondents, frequency matched to hip fracture patients on age, sex, and baseline functional limitations, the authors formed a single dataset and performed multivariable analyses of factors associated with functional decline. Gerontological research may benefit by applying these methods to programme evaluations and longitudinal analyses of health outcomes with numerous public-use datasets. (KJ/RH). |
