Effect of education based on the "4A Model" on the Iranian nurses' moral distress in CCU wards.

Complexity of health care has caused ethical dilemmas and moral distress to be quite unavoidable for nurses. Moral distress is a major, highly prevalent problem in the nursing profession. The study aims to investigate the effect of education based on the "4A model" on the rate of moral distress among the nurses working in Cardiac Care Units (CCU). The participants consisted of 60 nurses working in Cardiac Care Units (CCU), 30 in the control and 30 in the intervention group. Those in the intervention group took part in the educational workshop about "moral distress" and "4A model". The moral distress questionnaire was completed by both study groups 1 and 2 months after the intervention. After the intervention, the results of repeated measures analysis of variance revealed a significant difference in the moral distress mean scores between the intervention and the control groups (P<0.001) and within the two groups (P<0.001). Moreover, a significant difference was found between the two study groups regarding the mean score of moral distress 1 and 2 months after the intervention. The findings of the current study revealed a decreasing trend in the moral distress mean score in the intervention group, while there was an increasing trend in the control group after the intervention. It can be concluded that the "4A model" can be used for reducing moral distress and educational interventions can reduce the rate of moral distress among nurses. Authors of this study recommend that more studies with larger sample sizes be conducted in different hospital wards as well.
