Critical Incident Stress Management (CISM) - Benefit or Risk for Emergency Services?

Critical incident stress management (CISM) is widely used in emergency services as a practice originally rooted in critical incident stress debriefing (CISD). This review evaluates the status of medical and psychological literature on CISM’s efficacy and safety through database searches and analysis of study methodology. Findings from multiple studies indicate no preventive effect on psychiatric sequelae, including post-traumatic stress disorder (PTSD). Reports also suggest possible paradoxical worsening of stress symptoms, leading to conclusions that CISM should be used only with extreme caution and not as a mandatory intervention.

COLLECTIVE REVIEWS CRITICAL INCIDENT STRESS MANAGEMENT (CISM): BENEFIT OR RISK FOR EMERGENCY SERVICES? Bryan E. Bledsoe, DO, EMT-P ABSTRACT Background. Critical incident stress management (CISM) has become a common practice in modern emergency services. Described in 1983 as critical incident stress debriefing (CISD), CISM was originally marketed to help emergency personnel deal with ostensibly stressful situations they would encounter as a part of their work. Objective. To review the status of the medical and psychological literature regarding the efficacy and safety of CISM. Methods. Several pertinent databases were accessed and searched for scientific articles pertaining to CISM. These were subsequently analyzed for methodology and pertinence to the study topic. Results. Numerous scientific articles were found concerning CISM. Several high-quality studies were identified, but many other studies lacked adequate methodology sufficient for use in an evidence-based medicine approach. Others were from trade magazines, non-refereed journals, and obscure mental health journals. Several meta-analyses and randomized controlled trials (RCTs) were found. Overall, these studies show that, at best, CISM has no effect on preventing psychiatric sequelae following a traumatic event, particularly post-traumatic stress disorder (PTSD) . Furthermore, several studies report possible paradoxical worsening of stress-related symptoms in patients and personnel receiving CISM. Conclusions. Despite the limitations of the existing literature base, several meta-analyses and RCTs found CISM to be ineffective in preventing PTSD. Several studies found possible iatrogenic worsening of stress-related symptoms in persons who received CISM. Because of this, CISM should be curtailed or utilized only with extreme caution in emergency services until additional high-quality studies can verify its effectiveness and provide mechanisms to limit paradoxical outcomes. It should never be a mandatory intervention.

PREHOSPITAL EMERGENCY CARE 2003;7:272–279 Critical incident stress management (CISM) has become a common practice in emergency services. It was originally marketed to aid emergency services personnel in dealing with ostensibly stressful situations encountered as a part of their work. CISM was built around the use of critical incident stress debriefing (CISD) sessions that allow emergency personnel to openly discuss their feelings with peers and with mental health personnel. CISD was initially described by Mitchell in 19831 and has been subsequently modified and expanded by others to include the term “psychological debriefing” (PD) in describing the debriefing process.2 The hypothesis behind debriefing is that the cognitive structure of the event, such as thoughts, feelings, memories, and behaviors, is modified through retelling the event and experiencing emotional release, and this serves to reduce distress and prevent the emergence of post-traumatic stress disorder (PTSD) and other psychiatric sequelae.3 The initial CISD model, described by Mitchell, consisted of a team made up of a “partnership of mental health professionals [master’s degree or more in mental health] and peer support personnel. The major purposes of the CISD team [were] to prepare emergency personnel to manage their job-related stress and to assist emergency personnel who were experiencing the negative effects of stress after exposure to an unusually stre

FAQs

What is critical incident stress management (CISM) and where did it originate?

CISM is a practice used in emergency services, originally marketed based on critical incident stress debriefing (CISD) sessions designed to help personnel process stressful events. The approach was later expanded to include broader psychological debriefing concepts.

What does the review conclude about CISM’s effectiveness for preventing PTSD?

The review concludes that, despite limitations in the literature, meta-analyses and randomized controlled trials found CISM to be ineffective for preventing PTSD. Overall evidence does not support its preventive benefit.

Are there any potential risks reported with CISM?

Yes. Several studies report possible paradoxical worsening of stress-related symptoms in patients and personnel who receive CISM. Because of this risk, the intervention is recommended only with extreme caution.
