Mortality and hallucinations in nursing home patients with advanced Parkinson's disease

Abstract

We monitored 11 patients with advanced Parkinson's disease (PD) who entered nursing homes over a 5-year period and assessed chronicity of nursing home care, mortality, and hallucinatory status. Two years after the original study's close, none of these patients had ever been discharged from the nursing homes and all were dead. The mortality rate among the nursing home patients was significantly greater than that in 22 community-dwelling subjects with PD who were matched for age, gender, and disease duration. Hallucinatory status was generally stable; 82% of patients had the same hallucinatory status (presence or absence) at the two assessments. Four subjects from the original community-dwelling control group entered nursing homes during the follow-up period. Whereas motor and intellectual impairment scores were similar between these patients and the remaining 18 in the community, the presence of hallucinations was significantly greater among patients transferred to nursing homes. The study demonstrates the permanency of nursing home placement in advanced PD and the high mortality associated with such placement. It also documents the chronicity of hallucinatory behavior in these patients with advanced PD and reinforces our previously reported observations on the relationship between hallucinations and placement in chronic-care facilities.
