Critical care physicians and nurses have significant roles in the complex process of end-of-life decision making.

To understand how nurses' and physicians' emotions, psychosocial factors and professional roles influence end-of-life decision making in critical care.

An interpretive descriptive qualitative approach was applied to collect and analyse data from semi-structured interviews with five critical care nurses and four critical care physicians from April to June 2018.

Four Canadian critical care units; three tertiary and one rural setting.

Three major themes arose: (1) the goal of avoiding futility as a shared mission, (2) ambiguity of the decision making process; and (3) influencing factors of subjective variability. The significant influencers shaping the dynamic and value-laden process were individual philosophy, moral weightiness, and family receptiveness.

There is a need for a shared understanding of professional roles and clear communication of shared mission within health professional teams. Improved understanding of the end-of-life decision making process in critical care is essential to support nurses and physicians.
