Abstract
Longitudinal databases are an essential part of Medical Care Epidemiology and research on outcomes of elective surgery because of the need for followup measures of health status subsequent to behavioral and clinical interventions. The Medicare-aged population is worthy of study because they have high per-capita consumption of health care resources and stimululate development of new medical technologies. Data from Medicare's administrative system is available to qualified researchers and can be adapted to support investigations based on these methodologies. A database management and analysis strategy has been developed for linking together and reorganizing key files in HCFA's system to support such studies.
