Background: Physical restraints are regularly applied in German nursing homes. Their frequency varies substantially between centres. Beneficial effects of physical restraints have not been proven, however, observational studies and case reports suggest various adverse effects. We developed an evidence-based guidance on this topic. The present study evaluates the clinical efficacy and safety of an intervention programme based on this guidance aimed to reduce physical restraints and minimise centre variations.
Methods/design: Cluster-randomised controlled trial with nursing homes randomised either to the intervention group or to the control group with standard information. The intervention comprises a structured information programme for nursing staff, information materials for legal guardians and residents' relatives and a one-day training workshop for nominated nurses. A total of 36 nursing home clusters including approximately 3000 residents will be recruited. Each cluster has to fulfil the inclusion criteria of at least 20% prevalence of physical restraints at baseline. The primary endpoint is the number of residents with at least one physical restraint at six months. Secondary outcome measures are the number of falls and fall-related fractures.
Discussion: If successful, the intervention should be implemented throughout Germany. In case the intervention does not succeed, a three-month pre-post-study with an optimised intervention programme within the control group will follow the randomised trial.
