OBJECTIVES: To examine the relationship between race and mortality in frail community-dwelling older people with access to a program providing comprehensive access and coordination of services. DESIGN: A longitudinal cohort study. SETTING: Twelve nationwide demonstration sites of the Program of All-Inclusive Care for the Elderly (PACE) from 1990 to 1996. PACE provides comprehensive medical and long-term care services for nursing home-eligible older people who live in the community. PARTICIPANTS: Two thousand two white patients and 859 black patients. MEASUREMENTS: Patients were followed after enrollment until death or the end of the follow-up period. Time from enrollment to death was measured with adjustment of the Cox proportional hazards model for comorbid conditions, functional status, site, and other demographic characteristics. RESULTS: Black patients were younger than white patients (mean age 77 vs 80, P <.001) but had worse functional status (mean activity of daily living (ADL) score 6.5 vs 7.2, P <.001) on enrollment. Survival for black and white patients was 88% and 86% at 1 year, 67% and 61% at 3 years, and 51% and 42% at 5 years, respectively (unadjusted hazard ratio (HR) for black patients = 0.77; 95% confidence interval (CI) = 0.67-0.89). After adjustment for baseline comorbid conditions, functional status, site, and demographic characteristics, black patients still had a lower mortality rate (HR = 0.77; 95% CI =.65-0.93). The survival advantage for black patients did not emerge until about 1 year after PACE enrollment (HR for first year after enrollment = 0.97; 95% CI = 0.72-1.31; HR after first year = 0.67; 95% CI = 0.54-0.85, P-value for time interaction <.001). During the first year of enrollment, black patients were more likely to improve and less likely to decline in ADL function than white patients (P <.001). CONCLUSION: In PACE, a system providing access to and coordination of comprehensive medical and long-term care services for frail older people, black patients have a lower mortality rate than white patients. This survival advantage, which emerges approximately 1 year after PACE enrollment, may be related to the comprehensive access and coordination of services provided by the PACE program.
