Our aim was to explore reasons for physician variability in decisions to limit life support in the intensive care unit (ICU) utilizing qualitative methodology.
Single center study consisting of semi-structured interviews with experienced physicians and nurses. Seventeen intensivists from medical (n = 7), surgical (n = 5), and anesthesia (n = 5) critical care backgrounds, and ten nurses from medical (n = 5) and surgical (n = 5) ICU backgrounds were interviewed. Principles of grounded theory were used to analyze the interview transcripts.
Eleven factors within four categories were identified that influenced physician variability in decisions to limit life support: (1) physician work environment—workload and competing priorities, shift changes and handoffs, and incorporation of nursing input; (2) physician experiences—of unexpected patient survival, and of limiting life support in physician’s family; (3) physician attitudes—investment in a good surgical outcome, specialty perspective, values and beliefs; and (4) physician relationship with patient and family—hearing the patient’s wishes firsthand, engagement in family communication, and family negotiation.
We identified several factors which physicians and nurses perceived were important sources of physician variability in decisions to limit life support. Ways to raise awareness and ameliorate the potentially adverse effects of factors such as workload, competing priorities, shift changes, and handoffs should be explored. Exposing intensivists to long term patient outcomes, formalizing nursing input, providing additional training, and emphasizing firsthand knowledge of patient wishes may improve decision making.

Why do physicians make varying decisions to limit or continue life support?
Suppose two different physicians were treating the same patient, what factors would lead different decisions being made?

Which factors led to premature withdrawal of life support?
What does it mean to continue life support unnecessarily?
Can you given an example of when life support was continued unnecessarily?

Why did you disagree?
Can you give an example of when life support was continued and you disagreed?
Why did you disagree?
Have you ever felt regret regarding a decision to limit or continue life support?
Describe a situation in which a decision was made to limit life support and the end result was what you believed to be a good outcome.
What made it a good outcome?
Describe a situation in which a decision was made to limit life support and the end result was what you believed to be a poor outcome.
