BackgroundThe literature on moral distress highlights the need for hospitals and healthcare organizations to improve the work environment in critical care. However, only few studies delve into the types of intervention programs and administrative processes that can be put into effect to help nurses effectively deal with moral distress.AimThe aim of this study was to systematically synthesize evidence from published studies of interventions that address moral distress in critical care nurses. The attributes, measures, and outcomes of published interventions were described.MethodsSystemized literature review based on searches in four biomedical sciences databases (CINAHL, MEDLINE, COCHRANE, and SCOPUS). The Cochrane Collaboration's tool was employed for risk of bias. Eligibility criteria included published full-text articles exploring any type of intervention for critical care nurses' moral distress.ResultsBased on the selection criteria, seven studies were included in the review (two quasi-experimental, two randomized clinical trials, three mixed method). The majority of studies exhibited high risk of bias. Only two studies had moderate risk of bias. The most common type of interventions were workshops.ConclusionWe identified a small number of overall low-quality intervention studies, which provided weak evidence on the effectiveness of workshops for moral distress. Based on the indications for potentially large effect size of workshops, more well-designed studies are needed in order to elucidate the characteristics, content, and duration of effective workshops for moral distress. The results of this review can inform future efforts to develop and test intervention strategies for moral distress among intensive care unit (ICU) nurses.
