The COVID-19 pandemic has drawn increasing attention to the occupational stressors experienced by the health and medical professionals at the frontline of the pandemic (1-3). Traditional emergency service workers (police, fire, and ambulance) as well as frontline medical staff, including nurses and emergency doctors, work in highly unpredictable environments and are regularly exposed to physically and emotionally demanding conditions and potentially traumatic events as part of their occupation (4). This ongoing, chronic exposure to potentially traumatic events increases the risk of mental health conditions, including depression, anxiety, and posttraumatic stress disorder (PTSD) (5-7). According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the diagnosis of PTSD is characterized by four broad symptom clusters that include intense reliving of the traumatic event through disruptive memories and nightmares, avoidance of reminders of the event, negative cognitions and mood, and hyperarousal (8). It is estimated that 1 in 10 active emergency service workers (9), one in six retired emergency personnel (10), one in five frontline health workers, including nurses (11), and one in six emergency doctors (12) meet criteria for PTSD. Current PTSD treatment guidelines are focused on symptom reduction, with first-line treatments involving cognitive behavioral therapies and pharmacotherapy (13,14). There is, however, increasing recognition that not all people with PTSD benefit from available treatments, with efficacy of existing treatments often limited by cost, availability, and stigma preventing help-seeking behavior (15). Treatment outcomes are usually worse among those regularly exposed to trauma, such as emergency and frontline workers, as opposed to those with a single exposure (16).
