Systematic review of interventions to improve nurses’ work environments

Abstract

Aims: To evaluate the current evidence that examined the effects of nurses’ work environment interventions on nurse, patient, and hospital outcomes; and the key intervention characteristics.

Design: Quantitative systematic review without meta‐analysis.

Data Sources: Nine databases (British Nursing Index, CINAHL, EMBASE, Global Health, Global Health Archives, MEDLINE, Ovid Nursing, PubMed, and Web of Science) were searched following Systematic review Without Meta‐analysis guideline to elicit studies that examined effects of interventions aimed at improving nurses’ work environments among peer‐reviewed publications from inception to April 2019.

Methods: Database search used the following keywords: nurs*, patient, hospital, healthcare intervention, organizational improvement, nurs*adj4 outcome, patient adj4 outcome*, hospital adj4 outcome*, and their MeSH terms. The Cochrane's Risk of Bias in Non‐Randomized Studies of Intervention (ROBINS‐I) was used for quality appraisal. Donabedian model of Quality of Care was used as the framework to categorize interventions components focusing on structure and process aspects of the nurse work environments.

Results: The interventions included the use of accreditation process, educational strategies, and participatory approach. By defining the interventions which demonstrated positive effects on the nurse, patient, and hospital outcomes as effective, it appears that they are more consistently characterized as focusing on process improvement, adopting participatory approach, with greater involvement of frontline and nurse executives and at unit‐level implementation.

Conclusion: Although the heterogeneity in the design of the review studies precludes making conclusive insights on the best evidence to improve nurses’ work environments, the review informs the major research gaps in the topic area and the ways to design better interventions to enhance the outcomes.

Impact: The study provides insights on intervention components and strategies that can contribute to healthy nurse work environments. By adapting unit‐level process improvements that actively involve frontline and nurse executives, nurse leaders may provide a more directed approach towards achieving favourable outcomes.
