Purpose: The aim of this study was to identify the impact of age and factors on mortality of patients with community-acquired pneumonia in south korea.
Method: The study subjects were 11,076 patients aged 18 years and older that admission for community- acquired pneumonia(CAP). The data were obtained from Korean National Hospital Discharge In-depth Injury Survey in the 2008, 2013 and 2017. Logistic regression models were used to explore the impact of age on mortality of patients with CAP.
Result: The most influential factors of the mortality among pneumonia patients were age, emergency patients, and severity. The mortality risk of CAP increased significantly in from 2008(p<0.001) to 2017 (p<0.001). The highest risk of mortality was patients of over 80 years and the mortality risk of patients over 80 years was higher in 2017 (OR=15.92, 95% CI 6.39-39.66%) than in 2013(OR=10.04, 95% CI 4.01~25.14). The medical institutions characteristics was high the emergency room(OR=3.18, 95% CI 2.37~4.27), and the mortality risk was high for patients with length of stay 1-4 days in the medical use characteristics.
Conclusion: Age is a strong factor on mortality of patients with CAP. We recommend the use of severity marker that specifically reflect the age factors, and specific discussions are required for the implementation of the appropriateness evaluation considering age factors.
