An evaluation of increased mortality rates in Wisconsin nursing homes

We reviewed mortality data from 80 nonprofit and government-owned skilled nursing facilities (SNFs) to evaluate previously reported increases in deaths occurring in Wisconsin nursing homes since 1983. Comparing nursing home mortality data for 1982 and 1985, we found a 16.6% increase in overall nursing home mortality rates. The increased mortality rates occurred in the sample SNFs regardless of ownership, Medicare certification, bed size, metropolitan area and hospital affiliation. There were two explanations for the increased mortality rates. First, the number of residents dying within 30 days after nursing home admission increased 59%. The majority of these short-lived residents had been discharged from hospitals indicating a transfer of terminally ill patients into nursing homes just prior to death. Second, there was a 27% increase in the mortality rate of residents living in the nursing home for 1 to 5 years suggesting that the population had become sicker between 1982 and 1985. These data reflect both the impact of Medicares Prospective Payment System (PPS) on the study nursing homes and an increase in the severity of illness of Wisconsin's nursing home population between 1982 and 1985. The findings document an increased role for nursing homes in caring for more acutely ill patients since the passage of the PPS, and have implications for nursing home reimbursement policies and quality of care.
