Stress and substance abuse among workers during the COVID-19 pandemic in an intensive care unit: A cross-sectional study

OBJECTIVE: Professionals working in intensive care units (ICUs) during the COVID-19 pandemic have been exposed to stressful situations and increased workload. The association between symptoms of traumatic stress disorders, substance abuse and personal/occupational characteristics of Brazilian COVID-19-ICU workers is still to be addressed. Our aim was to evaluate the prevalence of those conditions and to find if those associations exist. METHODS: In this observational, single-center, cross-sectional study, all professionals working in a COVID-19 ICU were invited to fill an anonymous form containing screening tools for traumatic stress disorders and substance abuse, and a section with questions regarding personal and occupational information. RESULTS: Three hundred seventy-six ICU professionals participated. Direct exposure to patients infected by COVID-19, history of relatives infected by COVID-19, and sex (female) were significantly associated with signs and symptoms of traumatic stress disorders. 76.5% of the participants had scores compatible with a diagnosis of traumatic stress disorders. Moreover, the prevalence of scores suggestive of Tobacco and Alcohol abuse were 11.7% and 24.7%, respectively. CONCLUSION: ICU workers had significantly elevated scores on both screening forms. Providing psycho-social support to ICU professionals may prevent future problems with traumatic stress disorders or substance abuse.
