Evaluating the performance of long-term care (LTC) demonstrations requires longitudinal assessment of multiple outcomes where
selective mortality and disenrollment, if not accounted for, can give the appearance of reduced (or enhanced) efficacy. We
assessed outcomes in social/health maintenance organizations (S/HMOs) and Medicare fee-for-service (FFS) care using a multivariate
model to estimate active life expectancy (ALE). S/HMO enrollees and samples of FFS clients in four sites were analyzed and
outcome differences assessed for a 3-year period. Results provide insights into S/HMO performance under different conditions
and, more generally, into evaluating LTC demonstrations without randomized client and control groups.
