RESUMO
BACKGROUND: The West African Ebola virus disease (EVD) epidemic resulted in >28 000 disease cases and >11 000 fatalities. The unprecedented number of survivors from this epidemic has raised questions about the long-term mental health impacts of EVD survivorship and the capacity to meet these needs. OBJECTIVES: Assess the frequency and factors associated with mental health consequences of EVD survivorship in Sierra Leone. METHODS: A cross-sectional study of 595 EVD survivors and 403 close contacts (n=998) from Sierra Leone assessed via in-person survey between November 2021 and March 2022. The assessment included validated mental health screening tools (Patient Health Questionnaire-9, PTSD Checklist-5, Alcohol Use Disorders Identification Test, Drug Abuse Screening Test-20) to indicate the presence/absence of disorder. The frequency of each disorder and factors associated with each disorder were assessed. FINDINGS: EVD-associated post-traumatic stress disorder (PTSD) was reported by 45.7% (n=257) of EVD survivors. Moreover, 3.9% (n=22) and 12.0% (n=67) of EVD survivors reported major depression (MD) and substance use, respectively; all mental health outcomes were higher than baseline rates in the region (PTSD: 6%-16%, MD: 1.1%, substance use: 2.2%). PTSD among EVD survivors was associated with acute EVD duration of ≥21 days (adjusted OR, AOR 2.24, 95% CI 1.16 to 4.43), 35-44 years of age (AOR 3.31, 95% CI 1.33 to 8.24; AOR 2.99, 95% CI 1.09 to 8.24) and residential mobility (AOR 4.16, 95% CI 2.35 to 7.35). CONCLUSIONS: Concerningly, the levels of mental health disorders among EVD survivors in Sierra Leone remained elevated 6-8 years after recovery. CLINICAL IMPLICATIONS: Results can be used to inform policy efforts and target resources to address mental health in EVD survivors.
