Effect of interventions to improve safety culture on healthcare workers in hospital settings: a systematic review of the international literature.

BACKGROUND: In an era of safety systems, hospital interventions to build a culture of safety deliver organisational learning methodologies for staff. Their benefits to hospital staff are unknown. We examined the literature for evidence of staff outcomes. Research questions were: (1) how is safety culture defined in studies with interventions that aim to enhance it?; (2) what effects do interventions to improve safety culture have on hospital staff?; (3) what intervention features explain these effects? and (4) what staff outcomes and experiences are identified? METHODS AND ANALYSIS: We conducted a mixed-methods systematic review of published literature using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search was conducted in MEDLINE, EMBASE, CINAHL, Health Business Elite and Scopus. We adopted a convergent approach to synthesis and integration. Identified intervention and staff outcomes were categorised thematically and combined with available data on measures and effects. RESULTS: We identified 42 articles for inclusion. Safety culture outcomes were most prominent under the themes of leadership and teamwork. Specific benefits for staff included increased stress recognition and job satisfaction, reduced emotional exhaustion, burnout and turnover, and improvements to working conditions. Effects were documented for interventions with longer time scales, strong institutional support and comprehensive theory-informed designs situated within specific units. DISCUSSION: This review contributes to international evidence on how interventions to improve safety culture may benefit hospital staff and how they can be designed and implemented. A focus on staff outcomes includes staff perceptions and behaviours as part of a safety culture and staff experiences resulting from a safety culture. The results generated by a small number of articles varied in quality and effect, and the review focused only on hospital staff. There is merit in using the concept of safety culture as a lens to understand staff experience in a complex healthcare system.

Reporting standards, outcomes and costs of quality improvement studies in Ireland: a scoping review.

OBJECTIVES: To profile the aims and characteristics of quality improvement (QI) initiatives conducted in Ireland, to review the quality of their reporting and to assess outcomes and costs. DESIGN: Scoping review. DATA SOURCES: Systematic searches were conducted in PubMed, Web of Science, Embase, Google Scholar, Lenus and rian.ie. Two researchers independently screened abstracts (n=379) and separately reviewed 43 studies identified for inclusion using a 70-item critique tool. The tool was based on the Quality Improvement Minimum Quality Criteria Set (QI-MQCS), an appraisal instrument for QI intervention publications, and health economics reporting criteria. After reaching consensus, the final dataset was analysed using descriptive statistics. To support interpretations, findings were presented at a national stakeholder workshop. ELIGIBILITY CRITERIA: QI studies implemented and evaluated in Ireland and published between January 2015 and April 2020. RESULTS: The 43 studies represented various QI interventions. Most studies were peer-reviewed publications (n=37), conducted in hospitals (n=38). Studies mainly aimed to improve the 'effectiveness' (65%), 'efficiency' (53%), 'timeliness' (47%) and 'safety' (44%) of care. Fewer aimed to improve 'patient-centredness' (30%), 'value for money' (23%) or 'staff well-being' (9%). No study aimed to increase 'equity'. Seventy per cent of studies described 14 of 16 QI-MQCS dimensions. Least often studies reported the 'penetration/reach' of an initiative and only 35% reported health outcomes. While 53% of studies expressed awareness of costs, only eight provided at least one quantifiable figure for costs or savings. No studies assessed the cost-effectiveness of the QI. CONCLUSION: Irish QI studies included in our review demonstrate varied aims and high reporting standards. Strategies are needed to support greater stimulation and dissemination of QI beyond the hospital sector and awareness of equity issues as QI work. Systematic measurement and reporting of costs and outcomes can be facilitated by integrating principles of health economics in QI education and guidelines.
