The involvement of patients and families is essential for improving patient safety. However, the role of patients and caregivers in patient safety has recently been receiving attention, and programs and interventions have been implemented for patients and caregivers. The objective of this systematic review was to identify the types of interventions to improve patient safety that focused on engaging patients and their families, and the effectiveness of these interventions. Searching four electronic databases, 2019 articles were obtained; of these, 15 articles met the inclusion criteria. The studies used intervention strategies at the "information" and "involvement" engagement levels. Interventions with strategies only at the information level mostly measured safety perception and were mostly found to be effective. Interventions with both information and involvement strategies measured more diverse outcomes, but their effectiveness was inconsistent. Further studies using a range of intervention strategies and outcomes with more rigorous methodologies are needed.PROSPERO registration number CRD42018096162.
