BackgroundPhysicians are responsible for making decisions about the do not resuscitate (DNR) order of patients; however, most of them are faced with some uncertainty in decision making and ethical aspects. Moreover, there are differences on decision making related to the DNR order among physicians, which may be related to the different attitudes toward this issue. Considering the lack of information, this study was performed to investigate doctors’ attitude about DNR order for patients in their final phases of life.MethodsIn a descriptive–analytical study, 152 physicians were enrolled as quota sampling subjects from educational hospitals affiliated to the Kermanshah University of Medical Sciences. The tool used was a researcher-developed questionnaire. Data were analyzed using SPSS 16 software by descriptive and inferential statistics.ResultsThe mean of attitude toward DNR was 3.22, for which the univariate t-test showed a significant positive attitude toward DNR (P=0.002); the mean of attitude number toward DNR was higher in physicians with higher education level (P=0.002). But this difference was not found in terms of age group, sex, and experiences in participating in DNR decisions.ConclusionDue to the positive attitude of doctors toward DNR orders and lack of identified guidance, clear guidelines that comply with the Iranian Islamic culture are necessary to be established. Implementing this directive requires comprehensive training to various groups, including patients, doctors, nurses, administrators, and policy makers of the health system.
