Description: This study investigated the impact of the Medicare prospective payment system (PPS) developed in 1983 to replace the former retrospective payment system. This study was developed within the context of Applied General Systems Theory which proposes that system improvements will have negative effects (Spillover) on interfacing systems. It was hypothesized that changes in the Medicare system would cause Spillover to occur in patient and hospital systems. A multiple time series design was used. The dependent variables were severity of illness on day of admission, length of stay, referrals to home health agencies, and readmission rates. Data were collected at one hospital from randomly selected medical records of 120 Medicare beneficiaries, and for comparison, 120 non-Medicare beneficiaries admitted to the hospital for congestive heart failure from July 1, 1982 to June 30, 1986. Data were analyzed using MANCOVA at the alpha level of.05. There were no significant differences between Medicare patients before and after the implementation of the PPS. After controlling differences due to age and the existence of chronic illness, there were no significant differences between the Medicare and non-Medicare groups before and after the implementation of the PPS.
