Background: Decisions to forgo life-sustaining medical treatments in terminally ill patients are challenging, but ones that all doctors must face. Few studies have evaluated the impact of medical training on medical students' attitudes towards end-of-life decisions and none have compared them with an age-matched group of non-medical students.
Objective: To assess the effect of medical education on medical students' attitudes towards end-of-life decisions in acutely ill patients.
Design: Cross-sectional study.
Participants: Four hundred and two students at The Chinese University of Hong Kong.
Measurements: Completion of a questionnaire focused on end-of-life decisions.
Main results: The number of students who felt that cardiopulmonary resuscitation must always be provided was higher in non-medical students (76/90 (84%)) and medical students with less training (67/84 (80%) in year 1 vs. 18/67 (27%) in year 5) (p < 0.001). Discontinuing life-support therapy was more accepted among senior medical students compared to junior medical and non-medical students (27/66 (41%) in year 5 vs. 18/83 (22%) in year 1 and 20/90 (22%) in non-medical students) (p = 0.003). An unexpectedly large proportion of non-medical students (57/89 (64%)) and year 1 medical students (42/84 (50%)) found it acceptable to administer fatal doses of drugs to patients with limited prognosis. Euthanasia was less accepted with more years of training (p < 0.001). When making decisions regarding limitation of life-support therapy, students chose to involve patients (98%), doctors (92%) and families (73%) but few chose to involve nurses (38%).
Conclusions: Medical students' attitudes towards end-of-life decisions changed during medical training and differed significantly from those of non-medical students.
