Investigation of death clusters in a nursing home

The number of elderly residing in, and dying in, nursing homes is steadily increasing. In 1985, an investigation by the California attorney general's office was undertaken concerning a cluster of deaths in a single rural nursing home. The purpose of this study was to provide information for the investigation. The objectives of the study were to determine if there were excess deaths in the nursing home, and if so, to describe the circumstances surrounding the deaths and the policy implications for the quality of care in nursing homes. All the medical records for patients who died in a single nursing home between January 1, 1983 and April 30, 1985 were examined by the research team. Medical care was compared to desirable standards of care. A majority of the deaths, 52.5%, had major discrepancies from standard care that may have contributed to the patient's death. There were also major discrepancies in the cause of death between the death certificate and evidence from examination of the medical records. The data substantiated an unusual occurrence of deaths in the nursing home at the end of 1983 and again in early 1985, but no single factor or person could be identified as the major cause of the deaths. Although this is an isolated study of one nursing home, it is likely that these problems are not unique and the evaluation approach may be useful in other settings. It is recommended that nursing home deaths be routinely monitored, and that an unusual number of deaths should trigger an extensive investigation.
