Input: Four cluster-randomised controlled studies met the inclusion criteria. All of them investigated complex interventions comprising educational approaches. Three studies offered education and training for nursing staff, one study offered multidisciplinary team meetings as main component of the intervention. There was one high-quality study, but overall the methodological quality of studies was moderate.  The studies revealed consistent results for the primary end point. All studies documented a decrease of the proportion of residents with antipsychotic drug use or a reduction in days with antipsychotic use per 100 days per resident, respectively. In summary, the reviewed evidence on psychosocial interventions targeting professionals is consistent with a reduction of antipsychotic medication prescription in care home residents. However, owing to heterogeneous approaches, summary effect sizes cannot be determined. There is evidence to support the effectiveness of psychosocial interventions for reducing antipsychotic medication in care home residents. However, the review was based on a small number of heterogeneous studies with important methodological shortcomings. The most recent and methodologically most rigorous study showed the most pronounced effect.
Output:

This review investigates whether psychosocial interventions aimed at reducing antipsychotic medication in care homes are effective. By psychosocial interventions, we mean programmes that consist of different non-pharmacological components including talking to the staff, residents, or both. We identified four randomised controlled trials for inclusion in the review. All studies examined, among other components, education targeted at nursing staff in care homes. The methodological quality of three studies was limited, one study showed high quality. In all studies the interventions led to a reduction of antipsychotic medication use, but the overall magnitude of the effect remains unclear.
