Traditional Chinese medicine for the COVID-19 pandemic: An online cross-sectional survey among health care workers

Introduction: During the coronavirus disease (COVID-19) pandemic, health care workers (HCWs) faced a heightened risk of infection. Preventative measures are critical to mitigate the spread of COVID-19 and protect HCWs. Traditional Chinese medicine (TCM) has been recommended to prevent and treat COVID-19 in China. We conducted this survey to investigate the use of infection control behaviors, preventative and therapeutic in-terventions, and outcomes among HCWs during the surge of Omicron variant COVID-19 infections to explore the association of preventative measures with outcomes and to investigate the factors influencing the adoption of TCM as a preventative measure.Methods: The questionnaire consisted of 23 sections with 154 questions for HCWs. The targeted respondents comprised all HCWs from Xiamen Hospital Affiliated of Beijing University of Chinese Medicine. The recruitment process was open between March 17 and June 1, 2022. Chi-square test was used to estimate the relationship between prevention and outcomes. Multivariable logistic regression was used to investigate factors influencing the use of TCM as a preventative measure.Results: Among the 1122 participants who completed the questionnaire, 79.71% took preventative measures, including TCM (56.21%), physical activities (52.37%) and food supplements (26.99%). Xiamen preventative formula (a government-approved fixed prescription) (45.22%) and Lianhua Qingwen preparations (18.95%) were the most commonly used Chinese medicines. Thirty-six participants reported flu-like symptoms and three were diagnosed with COVID-19. Flu-like symptoms were not associated with prevention, vaccination, or TCM. Frontline working experience (OR = 0.61, 95% CI: 0.46-0.80), good knowledge of post-COVID-19 syndrome (OR = 0.57, 95% CI: 0.39-0.84), Western medicine qualifications (OR = 2.41, 95% CI: 1.51-3.86), being a nurse (OR = 1.70, 95% CI: 1.21-2.40), or medical technician (OR = 2.27, 95% CI: 1.25-4.10) were associated with the willingness to use TCM as a preventative measure.Conclusion: Complementary medicine, especially TCM, could be used for COVID-19 prevention. Knowledge of COVID-19 may prompt people to use TCM to prevent COVID-19. Multicenter studies and prospective cohort follow-up studies are needed to provide further insights into the use of TCM for COVID-19 management.
