Effect of Person-Centred-Care on Antipsychotic Drug Use in Nursing Homes: a Cluster-randomised Trial

Background: Up to 90% of nursing home residents with dementia experience behavioural and psychological symptoms like apathy, agitation, and anxiety. According to analyses of prescription prevalence in Germany, antipsychotic drugs seem to be prescribed as first line treatment of neuropsychiatric symptoms in persons with dementia. A huge number is prescribed for inappropriate reasons and too long without regular review. The use of antipsychotics is associated with adverse events like increased risk of falling, stroke, and mortality. This study aims to investigate whether a person-centered care approach developed in the United Kingdom can be adapted and implemented in German nursing homes. The aim of the investigators trial is to achieve a clinically relevant reduction of the proportion of residents with alt least one antipsychotic drug prescription.

Methods/Design: Cluster-randomised controlled trial comparing an intervention group (two-day initial skill training on person-centred care and on-going training and support programme) with a control group receiving optimised usual care. Both study groups will receive a medication review by an experienced psychiatrist with feedback to the prescribing physician. Overall, 36 nursing homes from East, North and West Germany will be included and randomised. The primary outcome is defined as the proportion of residents receiving at least one antipsychotic medication at 12 months. Secondary outcomes are residents' quality of life, behavioural and psychological symptoms of dementia as well as safety parameters like falls and fall-related medical attention. Cost parameters will be collected and process evaluation will be performed alongside the trial.
