To investigate the influenza vaccination willingness and influencing factors among elderly patients with chronic diseases in Chongqing, providing a scientific basis for the development of targeted vaccine policies and intervention measures.
A multi-stage sampling method was employed to randomly select 1 280 elderly patients with chronic diseases in five districts of Chongqing for an investigation into their influenza vaccination willingness. Univariate analysis was performed using the t-test and chi-square test, and binary logistic regression analysis and the standardized score were used to analyze the influencing factors of influenza vaccination willingness among elderly patients with chronic diseases.
Of the 1 211 eligible survey respondents, only 13.1% of elderly patients with chronic diseases had received the influenza vaccination during the 2022-2023 influenza season, and 56.3% were willing to receive the influenza vaccination in the 2023-2024 influenza season. The willingness to receive influenza vaccination among elderly patients with chronic diseases was higher among ethnic minorities (OR=3.49, 95%CI:1.21-10.02), households or unemployed individuals (OR=2.53, 95%CI:1.05-6.09), individuals with an average monthly household income per capita exceeding 5 000 RMB (OR=2.86, 95%CI:1.33-6.13), those with qualified knowledge of influenza vaccination (OR=1.38, 95%CI:1.02-1.87), and under the policy of free vaccination (OR=56.97, 95% CI:24.38-133.09). The behavioral and social drivers (BeSD) survey indicated that the belief in the effectiveness and safety of the influenza vaccine and fear of infecting friends or family members were the primary driving factors of influenza vaccine uptake, while the perception of the high costs of influenza vaccination was the most significant barrier.
The influenza vaccination willingness among elderly patients with chronic diseases in Chongqing needs further improvement. Governmental authorities, healthcare institutions, and communities should enhance the dissemination of knowledge about influenza vaccines, enhance social support, implement subsidies or free vaccination policies for priority populations, and encourage proactive influenza vaccine uptake among elderly patients with chronic diseases.
