Moral distress reduction using moral case deliberation in Japan: A mixed-methods study

This study aims to develop and examine the effectiveness of a support program for reducing moral distress of nurses, based on the moral case deliberation methodology, and to study the feasibility of its implementation.

Study design was an intervention study with pre/post-comparison. The support program included a short lecture and three moral case deliberation sessions for nurses working in an acute care hospital. The Measure of Moral Distress for Healthcare Professionals (MMD-HP) and the Euro-MCD (Moral Case Deliberation) 2.0 scale were used for pre/post-comparison, using the Wilcoxon's signed-rank test. Furthermore, post-intervention interviews were conducted with consenting participants to determine the reasons for changes in pre/post-intervention quantitative data. Of the 34 participants, 29 completed the post-questionnaire and were included in the quantitative data analysis, and 27 were included in the qualitative data analysis.

The mean MMD-HP total scores increased from 147.5 ± 61.0 to 159.3 ± 66.7, but not significantly (p = .375). The mean score of moral competence, a sub-scale of the Euro-MCD 2.0, increased significantly from 15.4 ± 2.4 to 16.4 ± 2.8 after the intervention (p = .036). A qualitative analysis revealed increased moral sensitivity to ethically difficult situations and improved analytical skills as the reasons for change in scores pre/post-intervention.

The results of the qualitative analysis suggested the effectiveness of the intervention. The moral distress score increased, although not significantly, and moral competence also increased, suggesting the participants' values changed after the intervention. It was found that the support program using MCD is expected to improve participants' moral competence.
