IntroductionPhysicians often encounter stressful situations that can impact their mental well-being. The death of a patient represents one of the most difficult situations in routine medical practice. Literature notably lacks comprehensive studies into physicians’ personal experiences with patients’ deaths. However, it does underscore heightened levels of sorrow, guilt, and stress stemming from the passing of terminally ill patients. As a majority of studies in this realm adopt qualitative methodologies, there is merit in supplementing existing research with a quantitative approach that employs validated psychometric scales. Furthermore, the study of phenomena associated with stress, particularly the perceived professional support by physicians in stressful events, can contribute to the implementation of preventive measures to help physicians cope. ObjectiveOur study aims to measure the traumatic impact on resident and intern physicians at national university hospitals following the death of patients, as well as to assess the perceived level of professional support among these physicians. Materials and methodsWe conducted a nationwide cross-sectional, descriptive, and analytical study. Participants included interns and residents from various specialties (medical, surgical and laboratory) at national university hospitals in Morocco. Assessing the traumatic impact of patients’ death on doctors was conducted using two psychometric scales: the Peri-Traumatic Distress Inventory (PDI) and the Revised Impact of Event Scale (IES-R). Additionally, we used the Perceived Professional Social Support Scale (QSSP-P) to evaluate how supportive the professional environment was towards these doctors. All scales utilized in the study are validated in the French language. ResultsThe study included 96 participants, with 67.7% being female. The average age was 26.8 years, ranging from 23 to 39 years. The majority of participants managed more than nine patients simultaneously (58.3%) while 41.7% were scheduled for more than six 24h shifts per month. During their training, over 64.6% of interns and residents faced more than ten patients’ death incidents, and 68.8% considered their first patient death as the most traumatizing. Half of the physicians evaluated the patients’ care as moderately appropriate, with 46.9% believing that the incident could have been prevented. Notably, 70.8% of interns and residents involved in patient care experienced self-blame and attributed a share of responsibility to themselves for the patient's demise. The majority of participants, 82.3%, exhibited peri-traumatic distress with a PDI score exceeding 15. Among the studied factors, only the perceived responsibility and a management system centered on a single physician (rather than a team) demonstrated a noteworthy correlation with PDI scores. The mean score on the IES-R scale was 25.6, with almost half of the sample (54.2%) reporting moderate to severe PTSD symptoms. The severity of these symptoms was significantly correlated with higher age, high number of patient's deaths experienced and the physician's perceived sense of responsibility. Participants in our study were more satisfied with support from colleagues compared to support functions (paramedical staff, administrative officials) or superiors. Moreover, only colleagues’ support was statistically significantly associated with low scores on the traumatic impact scales. ConclusionPhysicians maintain a unique relationship and therapeutic alliance with their patients. Therefore, the death of a patient can have a significant psychological impact on the physician. This study allowed us to objectively measure this psychological impact and evaluate professional support. The results of these studies encourage further exploration of the issue and the implementation of measures to reduce this psychological impact.
