Predictors of mortality in nursing home residents.

A prospective cohort study was conducted to examine predictors of mortality in the nursing home. Participants were 399 long-term nursing home residents, who were followed up for 11 years at the end of which 380 had died, 16 were still alive, 2 were discharged with unknown status, and 1 was alive when discharged. The median duration from baseline to death was 2.75 years. For cognitively intact residents, male gender, larger number of medical diagnoses, and manifestations of physically nonaggressive agitated behaviors (e.g., restlessness, pacing) were significant predictors. For cognitively impaired residents, the significant predictors were older age, impaired activities of daily living, and screaming behavior at a high frequency. Cognitive impairment is important both in predicting death in this population and in understanding the impact of other predictors. The impact of agitated behaviors, quality of social relations, and appetite on mortality highlights issues of quality of life at the end of life.
