Abstract:
PURPOSE: Healthcare-associated pneumonia (HCAP) has been proposed as a new category of pneumonia. However, epidemiological studies for HCAP in South Korea are limited. This study aimed to reveal the differences between HCAP and community-acquired pneumonia (CAP), especially in elderly patients, in university-affiliated hospital in South Korea. MATERIALS AND METHODS: We conducted a retrospective observational study of patients with HCAP and CAP (older than 60 years old) who were hospitalized between January 2007 and December 2008. We compared the baseline characteristics, comorbidities, severity, pathogen distribution, antibiotics, and clinical outcomes. RESULTS: A total of 210 patients were evaluated, including 35 patients with HCAP (17%) and 175 with CAP (83%). The most common causative organism was Streptococcus pneumoniae in CAP (33.3%), whereas, Staphylococcus aureus was most common pathogen in HCAP (40.0%). Initial inappropriate antibiotics (6.3% vs. 22.9%; p < 0.005) and initial treatment failure (15.4% vs. 31.4%; p = 0.018) were more frequent in HCAP than CAP. However, mortality (11.4% vs. 5.7%; p = 0.369) was not different between the two groups. CONCLUSION: The present study provides additional evidence that HCAP should be distinguished from CAP, even in elderly patients, in South Korea. Physicians should consider S. aureus and MDR pathogens in selecting initial empirical antibiotics of HCAP in South Korea.
