We carried out a postal survey of a sample of Finnish doctors ( n=1182) concerning their attitudes and ethical decisions in end-of-life care. A scenario was presented in which a patient with terminal cancer wished to obtain unorthodox treatment. Factors possibly influencing decision making such as general attitudes, life values and demographics were investigated. The response rate was 62%. The patient's plan to use unorthodox treatment was accepted by 54% of doctors. Gender or speciality did not influence the decision, but doctor's age was a significant factor ( P=0.0005). Doctors aged 35-49 years were more accepting; younger and older ones less accepting. Doctors who had clinical experience in terminal care were more compliant to the patient's plan ( P=0.034). A stepwise logistic regression analysis was used to create a model for explaining not accepting versus accepting the treatment with the background variables. Altogether eight independent significant variables were included in the final model of explaining a doctor's choice in the presented scenario. According to the model the patient's wish was more frequently accepted if the doctor was middle-aged, had clinical experience in terminal care, valued a high standard of living, considered terminal care satisfying, was less critical of health economics, considered advance directives helpful, had a high fear-of-death index score, and valued professional status less.
