abstract

  • Background Despite the wide distribution of different severity scoring systems for community-acquired pneumonia (CAP) patients, low-risk patients are frequently hospitalized, contrary to current recommendations. The aim of our study was to determine the rate, clinical characteristics, and outcome of low-risk patients with CAP admitted to our institution. Methods During an 18-month period, we prospectively screened all patients admitted to the Division of Internal Medicine with a presumptive diagnosis of CAP. Pneumonia Outcome Research Team (PORT) score and pneumonia severity index (PSI) were calculated for all patients during the first 24 h. Results A total of 591 patients had a diagnosis of CAP. Some 196 patients (33.1%) were low-risk (PSI class I, II), 98 (16.6%) intermediate (PSI III), and 297 (50.3%) high-risk patients (PSI IV, V). Patients in low-risk classes were younger (45.5 ± 15.8 vs. 65.0 ± 12.5 and 74.9 ± 11.8 years, respectively, p p p Conclusion The considerable proportion of low-risk patients hospitalized due to CAP was found to be comparable to the stable 30% rate reported in the literature. We conclude that physicians tend to opt for a wide safety range when considering a CAP patient hospitalization, rather than make a decision based only on severity score calculation.
