RESUMO
OBJECTIVE: Health-care associated pneumonia (HCAP) is a new category of pneumonia. We investigated differences of epidemiology, pathogens, and outcomes between HCAP patients in large hospitals and those in small hospitals. METHODS: This was a retrospective observational study of patients hospitalized with HCAP from December 2009 to March 2010. HCAP was defined according to ATS/IDSA criteria. A large hospital was defined as ≥ 200 beds and a small hospital was <200 beds. RESULTS: Of 117 patients, 61 patients were admitted to large hospitals and 56 patients were admitted to small hospitals. There was a significant difference of HCAP diagnostic criteria between the two groups. The A-DROP severity class was worse in the large hospital group than the small hospital group (P<0.05). Respiratory failure and disturbance of consciousness were more frequent in the large hospital group (P<0.05). The mortality rate was 8.2% in the large hospital group versus 1.8% in the small hospital group. Patients in the very severe A-DROP class had a high mortality rate of 33% in both groups. CONCLUSION: Patients with severe HCAP were more likely to be admitted to large hospitals. Patients in the very severe A-DROP class should receive intensive antibiotic therapy, but not all patients need broad-spectrum therapy.
