Abstract

Objective: Vaccination hesitance for the COVID-19 booster dosage among hemodialysis patients is an important barrier in reducing morbidity and mortality linked to COVID-19 infection. Hence, this study aimed to explore the predictors of the third (booster) dose of COVID-19 vaccine intention among CKD patients on hemodialysis from the Kingdom of Saudi Arabia (KSA).

Methods: This study was a multi-center cross-sectional study conducted at four dialysis centers in KSA from 13 February 2022 to 21 June 2022. The data was collected by the nephrologist in charge of the unit using a structured study questionnaire, which consisted of four parts; socio-demographic and clinical variables, questions about COVID-19 infection and subjective assessment of health state, COVID-19 booster dose vaccination intention and confidence in vaccines and preferences, and a health belief model. The study population consisted of 179 hemodialysis patients.

Results: Participants in the study had conflicting health beliefs about their vulnerability to COVID-19 infection and the severity of the COVID-19 infection. Study participants expressed positive health beliefs about the advantages of the COVID-19 booster dose, and reported less perceived obstacles in receiving the vaccine. The influence of cues on action among the study population was high. A total of 140 (78.2%) hemodialysis patients expressed their intention to receive the COVID-19 booster dose. Patients who reported poor health in the self-rating of their health status had a substantially higher definite intention to take the COVID-19 booster dose, according to the chi-square test (11.16, df = 3, p = 0.01). There was a significant association between the constructs in the HBM model and COVID-19 vaccine (booster) intention. Marital status (OR = 1.67, CI 1.07-2.58) was found to be the strongest predictors of a definite intention to receive a COVID-19 booster dose. Confidence in the locally manufactured vaccine (OR = 0.33, CI 0.17-0.60), education (OR = 0.62, CI 0.41-0.93), and rating of health status (OR = 0.43 CI 0.25-0.74) were the strongest significant correlates of having no definite intention to take the COVID-19 vaccination.

Conclusions: HBM constructs were found to be significantly associated with vaccination intention, which can be considered while planning policies to promote COVID-19 booster vaccination among hemodialysis patients. The study results could be utilized in drafting policies to improve COVID-19 booster dose vaccination uptake among hemodialysis population.
