    Published 2022-07-01
    “…Of those, 242 reported avoiding ED visits.Outcome measures Logistic regression models for ED avoidance were conducted to estimate the effect of risk perception and confidence in health services, adjusted for sociodemographics, health status and time.Results The adjusted odds for ED avoidance were higher for participants lacking confidence in health service response to non-COVID-19 conditions (adjusted OR: 6.39; 95% CI 3.19 to 12.82) and COVID-19 (1.81; 1.19 to 2.77) and lower for those perceiving a low risk of being infected at a health provider (0.16; 0.07 to 0.38).Conclusion In our sample, confidence in health services and risk perception of infection at a health provider were associated with the decision to avoid the ED. …”
