BackgroundCoronavirus disease 2019 (COVID-19) poses a significant threat to the safety of residents in long-term care facilities, and the staff of long-term care facilities are essential in the care and prevention of major infectious diseases and therefore require good health literacy to ensure the health of residents. The main objective of this study was to examine the health literacy of staff in long-term care facilities and analyze the factors associated with their COVID-19 health literacy in Taiwan to provide a basis for the response mechanism to emerging infectious diseases.MethodsA cross-sectional survey with a structured questionnaire by a convenience sample method and to assess the COVID-19 health literacy of caregivers working in long-term care facilities in this study. The COVID-19 health literacy scale was a self-administered scale designed to combine the concept of “health literacy” with the 3 levels and 5 stages of preventive medicine. A total of 385 workers from 10 long-term care facilities were surveyed as the study sample, and the validated questionnaires were statistically analyzed using SPSS version 22.0 statistical software. A multivariate logistic regression model was used to establish the associated factors of the COVID-19 health literacy level.ResultsOverall, the mean COVID-19 health literacy score was 88.7 ± 10.4 (range: 58–105). Using a quartile scale, 92 (23.9%) of the study participants had low health literacy (health literacy score < 82), 190 (49.3%) had average health literacy (health literacy score 82–98), and the remaining 103 (26.8%) had good health literacy (health literacy score 99–105). Statistical analysis revealed significant differences (p < 0.05) in the COVID-19 health literacy score by demographic variables (education, job category, number of daily service users, and training related to infectious disease prevention and control) of the study population. The logistic regression analysis of the COVID-19 health literacy level (> 82 vs. ≤82) showed a significant difference in the study sample by gender (male vs. female, OR = 2.46, 95% CI = 1.15–5.26), job category (nurse practitioner vs. caregiver, OR = 7.25, 95% CI = 2.46–21.44), monthly service hours (> 160 h vs. 40–79 h, OR = 0.044, 95% CI = 0.07–0.97), experience caring for confirmed COVID-19 patients (yes vs. no, OR = 0.13, 95% CI = 0.02–0.98), and training related to infectious disease prevention and control (yes vs. no, OR = 2.8, 95% CI = 1.52–5.15).ConclusionsThis study recommends that facilities provide immediate updated COVID-19 information to staff, especially frontline caregivers, and specifically enhance COVID-19 infection control education training for all facility staff to eliminate health literacy disparities.
