Abstract
This study analyzed services utilization before and after the implementation of Medicare's Prospective Payment System (PPS) in psychiatric patients with somatization disorder in two samples: one recruited before the PPS and the other after the PPS. Individuals with this psychiatric disorder present with multiple unexplained medical complaints and consume a great number of health resources. The results from this study indicated that Medicare PPS was associated with fewer hospital admissions and fewer hospital days, with a greater number of physician visits (for Medicare patients) and emergency room visits (for non-Medicare patients) and with lower overall health expenditures. However, there were no significant changes in the average length of stay after PPS. In contrast to previous studies, Medicare PPS was significantly associated with changes in service utilization by non-Medicare patients as well, a possible “spillover effect.” This study confirms the results from other research indicating that higher levels of efficiency may be achieved for certain psychiatric disorders through prospective payment mechanisms.
