Physicians' decisions to withhold and withdraw life-sustaining treatment

Abstract

Background: Few data are available about physicians' decisions in regard to withholding or withdrawing life-sustaining measures. We therefore studied internists' views on this subject.

Methods: We surveyed 1000 generalist and subspecialist internists about their views on withholding or withdrawing life-sustaining treatment. Thirty-two hypothetical cases were included. The effect of the demographic data on withholding or withdrawing treatment was analyzed via analysis of covariance and multiple logistic regression.

Results: Of 1000 internists, 407 (41%) completed and returned surveys. A majority of respondents (51%) were willing to withhold or withdraw treatment in all 32 scenarios; 49% were unwilling to withhold or withdraw in at least 1 scenario. Respondents were likely to withhold treatment in 14 of 16 scenarios compared with 13.7 of 16 scenarios for withdrawing treatments (P<.001). Respondents withheld or withdrew feeding tubes in 6.6 of 8 scenarios (P<.001) and antibiotics in 6.7 of 8 scenarios (P = .001) compared with ventilators (7.1 of 8 scenarios) and dialysis (7.3 of 8 scenarios). Respondents were less likely to withhold or withdraw treatments in nonterminally ill (12.9 of 16 scenarios) (P = .02) and alert patients (13.2 of 16 scenarios) (P<.001) compared with terminally ill patients (14.9 of 16 scenarios) and patients with dementia (14.5 of 16 scenarios).

Conclusions: A large percentage of internists would be unwilling to adhere to some of patients' wishes to withhold or withdraw life-sustaining treatment. The clinical scenario and type of treatment affect internists' decisions about whether they would withhold or withdraw such treatment.
