ASSESSMENT OF TREATMENT OUTCOMES AND SOME RISK FACTORS FOR MORTALITY OF COMMUNITY-ACQUIRED PNEUMONIA CAUSED BY STAPHYLOCOCCUS AUREUS IN THE ELDERLY POPULATION

Abstract

Objectives: Community-acquired pneumonia is a notable contributor to mortality from infectious diseases on a worldwide scale, especially in the older population. Staphylococcus aureus is a prevalent infection known to cause severe pneumonia, often leading to a high incidence of complications and fatality. The study's objective was to assess the treatment outcomes and some factors associated with mortality rates of Staphylococcus aureus pneumonia in older people. Subjects and method: A cross-sectional study was conducted with 93 patients diagnosed with Staphylococcus aureus pneumonia admitted to Can Tho Central General Hospital from April 2021 to May 2023. Results: The research results showed clinical outcomes including 30-day all-cause death rates and pneumonia-related complications were slightly higher in the age group over 60 compared to those aged 60 and under, but the difference was not statistically significant. After performing multivariate analysis, it was found that heart failure (OR = 5.68, 95% CI: 1.01-32.1, p = 0.049) and central nervous system disease (OR = 5.26, 95% CI: 1.32-20.9, p = 0.018) were found to be independent factors that increased the mortality rate in individuals aged over 60. Conclusion: Clinical practitioners should evaluate and manage comorbidities regarding heart failure and central nervous system diseases during treatment of Staphylococcus aureus pneumonia due to its elevated fatality rate, especially in old patients.
