Abstract
INTRODUCTION: We aimed to determine the indicators for poor long-term outcome in older adults with community-acquired pneumonia (CAP). METHODOLOGY: Patients with CAP requiring hospitalization were included in this retrospective study. The long-term mortality was defined as all-cause 1-year mortality following hospital admission. RESULTS: A total of 145 patients with CAP were recorded. The median age was 70 (18-103), of whom 94 (65%) were ≥ 65 years old and 86 (59.5%) were male. Long-term mortality rates following CAP requiring hospitalization were substantially high in both the younger (n = 16, 31.4%) and older adults (n=43, 45.7%). In univariate analysis, the Pneumonia Severity Index (PSI) (p = 0.007), mechanical ventilation (p > 0.001), mental status changes (p = 0.018) as well as the modified Charlson Comorbidity Index (p=0.001), presence of malignancy (p < 0.001) and hospital readmission (p < 0.001) were associated with long-term mortality in the older group. Our results revealed that the need for mechanical ventilation (OR = 47.61 CI = 5.38-500.0, p = 0.001) and hospital readmission (OR = 15.87 CI = 5.26-47.61, p < 0.001) were major independent predictors of 1-year mortality. CONCLUSIONS: Clinicians should consider the lethal possibilities of CAP even after hospital discharge. The need for mechanical ventilation and hospital readmission may predict long-term mortality. Therefore, the patients who have these predictors should be closely monitored.
