Abstract

     The study aimed to investigate the rate of vaccination of the COVID-19 booster dose and the factors associated with COVID-19 mortality in Nakhonhanom Province. The study design utilized was a retrospective cohort study. The population was categorized into two groups: Group 1 included patients diagnosed with COVID-19, totaling 20,888, while Group 2 comprised individuals who had received two doses of the COVID-19 vaccination; totaling 222,106. The data from January 1, 2020, to December 31, 2022, were utilized for the study and were collected using a data recorded form. Descriptive and inferential statistics were employed for data analysis by multiple logistic regression presented by adjusted odds ratio, 95% confidence interval.
     The results showed that Nakhon Phanom Province has a booster vaccination rate of 31.6 percent. Several factors associated with COVID-19 mortality were found to be statistically significant. Non-vaccination was a significant risk factor, with individuals who did not receive the COVID-19 vaccine booster dose being 15.7 times more likely to die from COVID-19 (AOR = 15.7, 95% CI = 4.9-50.0). Those who received only one dose of the vaccine had a 16-fold increased risk of death (AOR = 16.0, 95% CI = 4.8-52.6). Moreover, individuals aged 60 and above were 12.4 times more likely to die than those under 60 (AOR = 12.40, 95% CI = 6.83-22.52). Regarding the presence of seven chronic diseases, individuals with the presence of seven chronic diseases were three times more likely to die from COVID-19 compared to those without these conditions (AOR = 2.95, 95%CI = 1.68-5.17). The study results emphasize the importance of booster vaccinations in reducing mortality rates, as well as identifying key factors associated with COVID-19-related deaths. Both proactive and reactive surveillance measures should be implemented to decrease the mortality rate among COVID-19 patients.
