Effect of person centred care on antipsychotic drug use in nursing homes (EPCentCare) a cluster randomised controlled trial
Abstract Background antipsychotic drugs are regularly prescribed as first line treatment for neuropsychiatric symptoms in persons with dementia although guidelines clearly prioritise non pharmacological interventions. Objective we investigated a person centred care approach, which has been successfully evaluated in nursing homes in the UK, and adapted it to German conditions. Design a 2 armed 12 month cluster randomised controlled trial. Setting nursing homes in East, North and West Germany. Methods all prescribing physicians from both study arms received medication reviews for individual patients and were offered access to 2 h of continuing medical education. Nursing homes in the intervention group received educational interventions on person centred care and a continuous supervision programme. Primary outcome: proportion of residents receiving at least one antipsychotic prescription after 12 months of follow up. Secondary outcomes: quality of life, agitated behaviour, falls and fall related medical attention, a health economics evaluation and a process evaluation. Results the study was conducted in 37 nursing homes with n 1,153 residents (intervention group: n 493; control group: n 660) The proportion of residents with at least one antipsychotic medication changed after 12 months from 44.6% to 44.8% in the intervention group and from 39.8 to 33.3% in the control group. After 12 months, the difference in the prevalence was 11.4% between the intervention and control groups (95% confidence interval: 0.9 21.9; P 0.033) odds ratio: 1.621 (95% confidence interval: 1.038 2.532) Conclusions the implementation of a proven person centred care approach adapted to national conditions did not reduce antipsychotic prescriptions in German nursing homes.
