Background: Ethically difficult situations are frequently encountered by healthcare professionals. Moral case deliberation is one form of clinical ethics support, which has the goal to support staff to manage ethical difficulties. However, little is known which difficult situations healthcare teams need to discuss. Aim: To explore which kinds of ethically difficult situations interprofessional healthcare teams raise during moral case deliberation. Research design: A series of 70 moral case deliberation sessions were audio-recorded in 10 Swedish workplaces. A descriptive, qualitative approach was (...) applied, using thematic content analysis. Ethical considerations: An advisory statement specifying no objections to the study was provided from an Ethical Review Board, and consent to be recorded was assumed by virtue of participation in the moral case deliberation. Findings: Three themes emerged: powerlessness over managing difficult interactions with patients and next-of-kin, unease over unsafe and unequal care, and uncertainty over who should have power over care decisions. The powerlessness comprised feelings of insufficiency, difficulties to respond or manage patient’s/next-of-kin’s emotional needs or emotional outbursts and discouragement over motivating patients not taking responsibility for themselves. They could be uncertain over the patient’s autonomy, who should have power over life and death, disclosing the truth or how much power next-of-kin should have. Discussion: The findings suggest that the nature of the ethically difficult situations brought to moral case deliberations contained more relational-oriented ethics than principle-based ethics, were permeated by emotions and the uncertainties were pervaded by power aspects between stakeholders. Conclusion: MCD can be useful in understanding the connection between ethical issues and emotions from a team perspective. (shrink)
