Staff-to-resident abuse in nursing homes: a scoping review

Elder abuse in long-term care is an important public health concern with social, health-related, and economic implications. Staff-to-resident abuse is of particular interest since institutions should protect residents' rights and prevent harm. To provide an up-to date comprehensive overview of staff-to-resident abuse in nursing homes, we performed a scoping review considering types of abuse, their prevalence and associated factors, descriptions, experiences, and preventive interventions.

We performed a scoping review following the framework provided by Arksey and O'Malley. We searched MEDLINE (via PubMed), CINAHL, PsycINFO via Ovid, and Cochrane Library. Additionally, we performed free web searching using Google Scholar and checked relevant reviews. Two reviewers independently selected studies. We narratively synthesised the results.

Out of 3876 references retrieved by our search, we included 46 studies in 47 reports. The prevalence rates of abuse varied widely, ranging from 0 to 93% depending on the type of abuse. Associated factors of abuse at the staff, resident, and nursing home level were evaluated inconsistently. Abuse was perceived ambiguous: even though it was considered unacceptable, it was underreported. We found only four studies addressing preventive interventions. Of these, four made recommendations for intervention development. Only one study with an experimental design examined a multi-component intervention including education and mutual support.

The review yielded heterogenous evidence not allowing a concrete conclusion on prevalence and associated factors. However, the results show the significance of the problem and indicate that there are associate factors of abuse that can be influenced by appropriate interventions. These are amongst other staff education, organisational culture, and conditions. Further research should investigate the composition and content of preventive interventions and their potential to reduce abusive behaviours.
