Nursing literature frequently emphasises the benefits of person-centred approaches for healthcare quality and safety.

This umbrella review aimed to synthesise the combined evidence from systematic reviews assessing the impact of person-centred care interventions on patient safety.

A three-step review process included a preliminary review of literature, a comprehensive search, and manual searching of reference lists and forward citations of selected reviews. The review protocol was registered with Prospero (CRD42018090048).

Reviewers searched 10 databases for systematic reviews published in English-language peer-reviewed journals between 2000 and 2019: Academic Search Complete, CINAHL, Cochrane Library, EMBASE, JBI Database, Medline, ProQuest Health & Medicine, PROSPERO Register, PubMed and Scopus.

Covidence software was used to manage screening and eligibility. Two reviewers independently screened titles and abstracts, reviewed full texts of articles for eligibility, and appraised the quality of reviews using the JBI Critical Appraisal Checklist for Systematic Reviews and Research Syntheses.

From an initial total of 3412 potential titles, 16 reviews met the inclusion criteria. The selected reviews examined the impact of person-centred care for diverse groups of patients (children, adults and older people) in varied settings. Most systematic reviews assessed experimental studies, generally comparing person-centred interventions with ‘usual care’, often demonstrating limited evidence of impact on safety. Reviews addressed several patient safety outcomes relevant to nursing, including falls, infections, medication use and misuse, and mortality rates. The systematic reviews were generally well conducted, although several included studies of poor or fair quality.

Given the heterogeneity of the interventions, outcomes and research designs of studies included in the selected reviews, we were unable to draw unequivocal conclusions about the implications of person-centred care for patient safety in this umbrella review. However, there was some encouraging evidence that person-centred care initiatives may result in reduced rates of falls (in acute care and residential aged care settings). The review also highlighted reductions in agitation for people with dementia and some improvement in anti-psychotic medication use in older people with dementia.

Although abundant evidence exists demonstrating the positive effects of person-centred care on healthcare quality and on patient (and provider) wellbeing, there is little research focussing specifically on the impact of person-centred care on patient safety. Thus, there is scope for further high-quality nursing research into how person-centred interventions improve specific patient safety outcomes in order to inform more widespread adoption of person-centred practice.
