  • Title: Cholinesterase inhibitors do not alter the length of stay in nursing homes among patients with Alzheimer's disease: a prospective, observational study of factors affecting survival time from admission to death.
    Author: Wattmo C, Londos E, Minthon L.
    Journal: BMC Neurol; 2016 Aug 31; 16(1):156. PubMed ID: 27581368.
    Abstract:
    BACKGROUND: The survival time in nursing homes (NHs) in Alzheimer's disease (AD) might be affected by sociodemographic/clinical characteristics, rate of disease progression, and use of specific medications and community-based services. Whether different aspects of cholinesterase inhibitor (ChEI) therapy modify time spent in NHs is unclear. Therefore, we examined the relationship between these potential predictors and survival time in NHs. METHODS: This prospective, multicenter study of ChEI treatment in clinical practice included 220 deceased patients clinically diagnosed with mild-to-moderate AD who were admitted to NHs during the study. Cognitive and activities of daily living (ADL) performance, ChEI dose, and amount of services used/week were evaluated every 6 months over 3 years. Dates of nursing-home placement (NHP) and death were recorded. Variables that determined survival time in NHs were analyzed using general linear models. RESULTS: The mean survival time in NHs was 4.06 years (men, 2.78 years; women, 4.53 years; P < 0.001). The multivariate model showed that a shorter stay in NHs was associated with the interaction term male living with a family member, use of antihypertensive/cardiac therapy or anxiolytics/sedatives/hypnotics, and worse basic ADL at NHP, but not with age or cognitive and instrumental ADL capacities. CONCLUSIONS: Increased community-based care did not reduce the survival time in NHs among individuals with AD. Men living with family spent significantly less time in NHs compared with the corresponding women, which suggests that the situation of female spouses of AD patients may need attention and possibly support. There was no indication that different aspects of ChEI therapy, e.g., drug type, dose, or duration, alter survival time in NHs.
