Understanding the impact of chronic diseases on COVID‐19 vaccine hesitancy using propensity score matching: Internet‐based cross‐sectional study

Abstract

AbstractAims and ObjectivesTo investigate whether chronic diseases are associated with higher COVID‐19 vaccine hesitancy and explore factors that influence COVID‐19 vaccine hesitancy in patients with chronic diseases.BackgroundVaccine hesitancy has been acknowledged as one of the greatest hazards to public health. However, little information is available about COVID‐19 vaccine hesitancy among patients with chronic diseases who may be more susceptible to COVID‐19 infection, severe disease or death.MethodsFrom 6 to 9 August 2021, we performed an internet‐based cross‐sectional survey with 22,954 participants (14.78% participants with chronic diseases). Propensity score matching with 1:1 nearest neighbourhood was used to reduce confounding factors between patients with chronic diseases and the general population. Using a multivariable logistic regression model, the factors impacting COVID‐19 vaccine hesitancy were identified among patients with chronic diseases.ResultsBoth before and after propensity score matching, patients with chronic diseases had higher COVID‐19 vaccine hesitancy than the general population. In addition, self‐reported poor health, multiple chronic diseases, lower sociodemographic backgrounds and lower trust in nurses and doctors were associated with COVID‐19 vaccine hesitancy among patients with chronic diseases.ConclusionsPatients with chronic diseases were more hesitant about the COVID‐19 vaccine. Nurses should focus on patients with chronic diseases with poor health conditions, low socioeconomic backgrounds and low trust in the healthcare system.Relevance to Clinical PracticeClinical nurses are recommended to not only pay more attention to the health status and sociodemographic characteristics of patients with chronic diseases but also build trust between nurses and patients by improving service levels and professional capabilities in clinical practice.Patient or Public ContributionPatients or the public were not involved in setting the research question, the outcome measures, or the design or implementation of the study. However, all participants were invited to complete the digital informed consent and questionnaires.
