Interventions to reduce moral distress in clinicians working in intensive care: A systematic review

To evaluate the effectiveness of interventions to mitigate the harmful effects of moral distress experienced by nursing and medical clinicians working in the intensive care setting.

Eligible studies were identified from searches of PubMed, EBSCO (Academic Search Complete, CINAHL and Medline) and Scopus. Included studies were published prior to 20 August 2020.

Twelve studies were included in this review comprising three randomised controlled trials, seven quasi-randomised trials and two observational studies. Nine studies reported interventions targeting only nurses while three included both nurses and doctors. The types of interventions identified included: moral empowerment programs, end-of-life educational programs, reflective exercises through individual narrative writing or group reflective debriefing, multidisciplinary case debriefing meetings integrated into clinical practice and moral resiliency training. Due to the overall low methodological quality and high risk of bias, no single intervention may be considered efficacious in managing moral distress.

There is weak evidence that some currently available interventions reduce the moral distress experienced by intensive care health care providers. Larger randomised trials involving all intensive healthcare clinicians are required to evaluate multifaceted interventions.
