The impact of occupational hazards and traumatic events among Belgian emergency physicians.

Background: Emergency Physicians (EPs) are regularly confronted with work related traumatic events and hectic work conditions. Several studies mention a high incidence of post-traumatic stress disorder (PTSD) and psychosomatic complaints in EP. The main objective of this study is to examine the contribution of demographics, traumatic events, life events, the occurrence of occupational hazards and social support to post-traumatic stress symptoms (PTSS), psychological distress, fatigue, somatic complaints and job satisfaction in Emergency Physicians.

Methods: For this study questionnaires were distributed to Belgian Emergency Physicians, These include, as determinants socio-demographic characteristics, traumatic events, life events, the occurrence of physical hazards, occurrences of violence, occurrence of situations that increase the risk of burnout and social support by supervisors and colleagues (LQWQ-Med), and as outcomes PTSS (IES), psychological distress (BSI), somatic complaints (PHQ 15), perceived fatigue (CIS20 R) and job satisfaction (LQWQ-MD). The response rate was 52.3 %. Hierarchical multiple regression analysis was performed to examine the association between the determinants and each of the outcomes.

Results: Emergency Physicians are particularly vulnerable to post-traumatic and chronic stress consequences due to repetitive exposure to work related traumatic incidents such as serious injuries or death of a child/adolescent. One out of three Emergency Physicians met sub-clinical levels of anxiety and 14.5 % met a clinical level of PTSD, short for Post-Traumatic Stress Disorder. Levels of fatigue were high but not directly related to traumatic events and occupational hazards. Social support from colleagues was found to have a beneficial effect on these complaints. Job satisfaction seems to have a protective factor. All of these not only affect the Emergency Physicians themselves, but can also have an adverse impact on patient care.

Discussion: EPs are, according to our and other studies, confronted on a regular basis with significant, potentially traumatizing work related events. There is a higher perception of traumatic events in older Eps. We find out that 36 % of the EPs find dealing with sudden death of a young person and traumatic accident/disease involving a young person the most traumatic experience during their work activity. Three quarter of these EPs have children of their own. The results of the study show that frequency of exposure to traumatic (work) events contributes next to occurrence of situations that increase the risk of burnout to the explanation of variance in posttraumatic stress and psychological distress. The novelty of this study is that it explores the effect of specific determinants of PTSS, psychological distress, fatigue, somatic complaints and job satisfaction in Emergency Physicians. Especially occurrence of situations that increase the risk of burnout seems to have a major impact on all outcomes including job satisfaction, while occurrence of violence contributes especially to psychological distress and perceived fatigue. Lack of social support is a well-known predictor of occupational stress in emergency care workers. In contrast however, good social support of colleagues at work, as we found in our study, can facilitate the recovery process after confrontation with traumatic events and occupational hazards.

Conclusion: Emergency Physicians are particularly vulnerable to post-traumatic stress and chronic stress consequences due to repetitive exposure to work related traumatic events. Training in dealing with violence and situations that can increase the risk of burnout can reduce detrimental consequences in emergency physicians. In addition, it is suggested that emergency units are screened systematically on determinants of burnout, in view of interventions. Finally, creating a supportive work environment and training the medical staff in supportive skills with backup by experts may also reduce adverse consequences of confrontation with traumatic work events.
