Abstract:
BACKGROUND : Post-traumatic stress symptoms (PTSS) have been described in healthcare workers after disease outbreaks.
Anaesthetists are at high risk of exposure to COVID-19 due to the nature of the airway procedures they perform. Anaesthetists
are also at increased risk of mental health disorders, substance abuse and suicide. When the occurrence of PTSS is great in both
number and severity, these become the key elements of the diagnostic criteria for post-traumatic stress disorder (PTSD). This study
explores the prevalence and predisposing factors of PTSS in anaesthetists during the second wave of COVID-19 in South Africa.
METHODS : Members of the South African Society of Anaesthesiologists (SASA) completed an electronic questionnaire regarding
their sociodemographic information as well as COVID-19 exposure. The PTSD checklist for DSM-5 (PCL-5) was used to measure
PTSS. The resulting score gave an indication of symptom severity, with a score of 33 or higher indicating a provisional diagnosis of
PTSD.
RESULTS : A total of 483 participants completed the questionnaire (23.8% response rate). Of these, 391 participants were included
in the study and 69 participants (17.6%) received a provisional PTSD diagnosis. Participants who are younger and have less
experience, who are female, who are single or who do not have children exhibited a greater prevalence of PTSD. Also, those
participants who had pre-existing mental health conditions (p = 0.009), and those who reported loneliness (p < 0.001) and poor
social support (p = 0.018) were more likely to receive a provisional PTSD diagnosis. Personal protective equipment (PPE) shortages
were also associated with the development of PTSD (p = 0.009).
CONCLUSION : The prevalence of PTSS is unacceptably high among South African anaesthetists, especially those with pre-existing
mental health conditions and poor social support. This calls for support of vulnerable healthcare workers during disease pandemics.
