Abstract
INTRODUCTION: Seasonal influenza vaccination (IV) is considered the most effective way in the prevention of influenza among older people. However, few studies have examined the effectiveness of IV on disabled populations. This study aimed to compare the effectiveness of IV for elderly people with and without disabilities on the risk of mortality and hospitalization in Taiwan. METHODS: This is a population-based, retrospective cohort study. By linking the National Disability Registration System and the National Health Insurance (NHI) Research Database, a total of 394,511 disabled and 2,741,425 free-of-disability adults age 65 or older in 2014, were identified. IV records were derived from the NHI database between October 1 and December 31, 2014, when the seasonal IVs were administered for free. Four comparison groups were formed by cross-tabulating the two dichotomies of vaccination-or-not and disability-or-not. Logistic regressions were used to compare these four groups of subjects on their health outcomes measured between January 1 and March 31, 2015. RESULTS: About 34.6% of the disabled elderly received IV in 2014, which was higher than that of free-of-disability elderly (30.8%). When compared to the unvaccinated disabled elderly, the vaccinated free-of-disability elderly had a 65% significant lower all-cause mortality; and 50.7%, 48.8%, 58.8%, and 36.7% lower risks of hospitalization for pneumonia and influenza, respiratory diseases, respiratory failure, and heart disease, respectively (p<0.001). DISCUSSION: This study indicated IV could reduce the risk of all-cause mortality and hospitalization of influenza-related complications. Findings supported that promoting IV could narrow health disparities between the disabled and general elderly populations.
