Cohorte characteristics :
- 377 Chinese caregivers from different provinces that had completed the questionnaire, 6 were excluded, therefore 371 participants for analysis. 38.5% men and 61.5% women. Average age 35.3 years, average education level : baccalaureate. 96.8% outside Wuhan. 18.1% doctors, 71.2% nurses, 10.2% others (medical technicians for example). 66% confined to home and no longer exposed, 34% on the front line. COVID-19 exposure level : low for 77.6%, moderate for 19.1% and high for 3.2% (12 participants).
- Prevalence of Posttraumatic Stress Symptoms (PTSS): 3.8% compatible with a PTSS table (PCL-5 score greater than or equal to 33). Invasive symptoms were prominent (positivity rate of 44.5%). Women seemed more exposed with a significantly higher rate of invasive symptoms than men (HR = 2.136 p = 0.01). Caregivers located in Wuhan were 4 times more at risk of showing symptoms of hypervigilance (HR = 4.026 p = 0.021).
- Quality of sleep: 2.7% reported very poor satisfaction, 11.3% reported frequent sleep disturbances, 6.7% complained of difficulty falling asleep, 6.2% slept less 6 hours a night. Caregivers with high exposure had significantly more sleep disturbance and difficulty falling asleep. Significant difference in the total sleep quality score between those with a PTSS and those without one (Z value = 6.014, p < 0.001), and between groups with different contact frequencies (Chi2 = 7.307, p = 0.026).
- Level of exposure correlated with satisfaction with sleep (p = 0.018), sleep disturbance (p = 0.002) and difficulty falling asleep (p = 0.001); correlated only to symptoms of hypervigilance in the PTSS (p = 0.003).
- Only the female gender seemed to predict a higher PCL-5 score.
- Correlation between sleep quality and presence of PTSS (coefficient = 1.700, p < 0.001), leading to an indirect correlation between level of exposure and presence of PTSS (coefficient = 1.750, 95% CI of Boostroop test = 0.543-2.998).
- Descriptive cross sectional observational study
- Low numbers: 371 caregivers, only 34% of whom are directly exposed to COVID-19
- Potential bias in reporting and confusion not taken into account.
Assess post traumatic stress disorder symptoms (PTSS) and the quality of sleep in Chinese caregivers on the front line against the COVID-19 epidemic after one month of exposure.
