OBJECTIVES: Antipsychotics are often prescribed to persons with cognitive impairment in the hospital, but it is not known whether recent hospital care increases the risk of antipsychotic initiation in community dwellers with Alzheimer's disease (AD). We studied whether hospital care during the previous 2 weeks is associated with antipsychotic initiation in persons with AD.
DESIGN: Register-based study.
PARTICIPANTS AND SETTING: The nationwide Medication use and Alzheimer's disease (MEDALZ) cohort containing Finnish community dwellers with AD between 2005 and 2011 (N = 70,718) was used.
METHODS: Incident antipsychotic use was identified with a 1-year washout period. Each new initiator was matched with noninitiator according to age, sex, and time since AD diagnosis (n = 22,281 matched pairs). The use of antipsychotics was identified from the Prescription Register. Information on hospital discharge within the past 2 weeks of antipsychotic initiation was extracted from the Hospital Discharge Register.
RESULTS: Antipsychotic initiators were 5 times more likely to have recently been discharged from the hospital compared with the matched noninitiators (29.8% and 5.3%, respectively). In adjusted regression analyses, a hospital stay longer than a week and especially more than 2 months [odds ratio (OR) 4.40, 95% confidence interval (CI) 3.51-5.53], use of benzodiazepines and related drugs (OR 1.66, 95% CI 1.44-1.92), and memantine (OR 1.30, 95% CI 1.12-1.52) were associated with antipsychotic initiation. Older age (OR 0.77, 95% CI 0.62-0.95), asthma or chronic obstructive pulmonary disease (OR 0.73, 95% CI 0.60-0.89), diabetes (OR 0.82, 95% CI 0.69-0.97), and cardiovascular disease (OR 0.82, 95% CI 0.72-0.94) were associated with a lower risk of initiation.
CONCLUSIONS AND IMPLICATIONS: Recent hospital care seems to be a risk factor for antipsychotic initiation in community-dwelling persons with AD. The need of antipsychotic treatment must be carefully assessed at the time of discharge. Well planned hospital discharge and home care might reduce antipsychotic initiation.
