Resident-to-resident aggression (RRA) is an important issue in congregate residential facilities (CRFs) for older adults and has devastating effects. This study aimed to provide an inventory and content analysis of the practices used to counter RRA and promote wellness care for older adults in CRFs. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, original, peer-reviewed research and systematic reviews published in 14 electronic databases and two gray literature sources were examined. Of the 6196 articles identified, 28 met the inclusion criteria. Practices aimed to prevent, track or intervene in RRA, mostly in long-term care centers, but few were evidence-based and ready for widespread implementation. It emerges that continuous training of staff is necessary and that it should prioritize a person-centered approach. CRFs' managers must promote a culture of wellness care and policymakers should consider the prevention practices to improve the quality of life of older adults in CRFs.
