Background Unit-based critical care nurse leaders (UBCCNL) play a role in exemplifying ethical leadership, addressing moral distress, and mitigating contributing factors to moral distress on their units. Despite several studies examining the experience of moral distress by bedside nurses, knowledge is limited regarding the UBCCNL’s experience. Research aim The aim of this study was to gain a deeper understanding of the lived experiences of Alabama UBCCNLs regarding how they experience, cope with, and address moral distress. Research design A qualitative descriptive (...) design and inductive thematic analysis guided the investigation. A screening and demographics questionnaire and a semi-structured interview protocol were the tools of data collection. Participant and research context Data were collected from 10 UBCCNLs from seven hospitals across the state of Alabama from February to July 2023. Ethical considerations This study was approved by the Institutional Review Board at the University of Alabama in Huntsville. Informed consent was obtained from participants prior to data collection. Findings UBCCNLs experience moral distress frequently due to a variety of systemic and organizational barriers. Feelings of powerlessness tended to precipitate moral distress among UBCCNLs. Despite moral distress resulting in increased advocacy and empathy, UBCCNLs may experience a variety of negative responses resulting from moral distress. UBCCNLs may utilize internal and external mechanisms to cope with and address moral distress. Conclusions The UBCCNL’s experience of moral distress is not dissimilar from bedside staff; albeit, moral distress does occur as a result of the responsibilities of leadership and the associated systemic barriers that UBCCNLs are privier to. When organizations allocate resources for addressing moral distress, they should be convenient to leaders and staff. The UBCCNL perspective should be considered in the development of future moral distress measurement tools and interventions. Future research exploring the relationship between empathy and moral distress among nurse leaders is needed. (shrink)
