A home-based geriatric assessment, follow-up and health promotion program: design, methods, and baseline findings from a 3-year randomized clinical trial.
Controlled trials in a number of countries have documented benefits from different types of in-home assessment and treatment programs for various subgroups of elderly persons. We have developed a program to test, using a randomized controlled design, the concepts of in-home comprehensive geriatric assessment (CGA) coupled with follow-up, health education, and preventive care in an urban United States community. The intervention includes yearly in-home CGA by geriatric nurse practitioners (GNPs), who provide, following discussions with physician geriatricians, lists of specific recommendations for health and well-being enhancement. The GNPs provide follow-up visits quarterly and regular telephone contacts to improve compliance. We recruited for our trial 414 home-living subjects aged 75 years and over, 215 randomized to the intervention group and 199 to the control group. Subjects were generally representative of the overall elderly population of the city of Santa Monica, a seaside suburb of Los Angeles. Extensive baseline data (medical, functional, psychosocial and environmental) were collected from subjects prior to randomization, using validated instruments whenever possible. Follow-up data were collected from each subject every 4 months by trained research assistants throughout the 3-year intervention follow-up period. Our study was designed to assess effects of the intervention on the hypothesized outcomes of health status, functional status, psychosocial parameters, and service utilization. Careful documentation of the intervention will enhance our ability to make process-outcome comparisons. Preliminary analysis reveals that the in-home CGA uncovered many important health deficits for most subjects resulting in a number of substantial recommendations. We are confident that when it is completed, this study will succeed in answering important remaining questions about the feasibility and effectiveness of establishing a geriatric in-home prevention and health promotion program in the United States based on principles of CGA.
