First responders are susceptible to posttraumatic stress disorder after witnessing traumatic events while on duty.
Stress from traumatic events as well as occupational stress affects workforce stability.
Organizational changes in the workplace can mitigate the effects of traumatic events for first responders.
First responders include but are not limited to paramedics, hospital emergency staff, firefighters, and police officers. Due to the nature of their work, first responders witness traumatic events that involve the injury or death of patients or civilians and/or experience direct threats (Alden et al. 2008).
Between 7-37% of first responders have posttraumatic stress disorder (PTSD) symptoms (Table 1). First responders also suffer from other mental disorders related to depression and anxiety (Regehr et al. 2010, Carleton et al. 2018).
PTSD in first responders has been associated with health-related problems such as high cortisol levels, high resting heart rates, and poor sleep quality (Bergen-Cico et al. 2015). In a Canadian survey, paramedics indicated they had struggled with alcohol abuse after exposure to a traumatic event (Regehr et al. 2010).
Barriers and stigma prevent first responders from seeking mental healthcare. First responders fear judgement and negative impacts on their careers, and experience shame for feeling trauma symptoms (Royle et al. 2009, Haugen et al. 2017). Barriers for first responders accessing mental healthcare include difficulty (Haugen et al. 2017):
In the U.S., a survey of hospitals found 23% and 15% of emergency nurses left their positions in 2017 and 2018, respectively (Castner et al. 2021). Compared to all registered nurses, a higher percentage of emergency nurses left their job in 2017.
Another survey of EMS agencies found that about 63% of agencies had turnover in the past six months, with an overall average annual turnover rate of 11% (Patterson et al. 2010).
In a study of nine states, 80% of EMTs stayed in the workforce from 2017 to 2019 and 82% stayed from 2018 to 2020 (Kurth et al. 2023). The per-state rate of EMTs leaving the workforce ranged from 16-26%.
Having positive working relationships, social support from the community, and acknowledgment of a first responder’s role can mitigate psychological stress (Vaughan et al. 2016, Lawn et al. 2020, Bevan et al. 2022). Some Canadian emergency rooms identified lack of staff as leading to greater exposure to trauma due to people handling more patients at once or working double shifts (Vaughan et al. 2016). Additionally, self-compassion is correlated with resilience against stressors (Lanza et al. 2018).
One study suggests organizations should provide designated time for workers to find closure after a traumatic event (Vaughan et al. 2016). It also found that supervisors need to be able to identify posttraumatic stress symptoms in workers and push them to find care. In a study of fire and police personnel, adding a standardized PTSD screening protocol increased the rate of positive PTSD diagnoses from 1% to 5% (Robertson 2019). In addition, civilian responders particularly struggle with trauma because they lack access to occupational resources.
Evidence suggests trauma-focused psychotherapies can also reduce posttraumatic stress symptoms in first responders (Alden et al. 2021). See our Science Notes Posttraumatic Stress Disorder and Medical Psilocybin Use for an overview on PTSD treatments and the potential role psilocybin has in treating certain disorders.
