BACKGROUND: Current American Thoracic Society (ATS) community-acquired pneumonia treatment guidelines recommend azithromycin monotherapy for a limited subset of hospitalized patients. We evaluated the effectiveness of azithromycin monotherapy in a more generalized population of patients hospitalized with mild-to-moderate community-acquired pneumonia. METHODS: We reviewed medical records from a Veterans Affairs facility for patients admitted with community-acquired pneumonia between December 1, 1997, and June 30, 2001, comparing those receiving azithromycin monotherapy, other ATS-recommended antibiotics, and non-ATS-recommended antibiotics. We excluded patients with immunosuppression, metastatic cancer, or hospital-acquired pneumonia. Outcome measures included times to stability, meeting criteria for change to oral therapy, and eligibility for discharge; length of stay; intensive care unit transfer; and mortality. Outcomes were adjusted for pneumonia severity, skilled nursing facility status, and processes of care. RESULTS: A total of 442 patients were eligible for the study (221 in the azithromycin monotherapy group, 129 in the ATS group, and 92 in the non-ATS group). Times to clinical stability and to fulfilling early switch criteria were not statistically significantly different among the 3 groups. Mean time to fulfilling early discharge criteria was 2.48 days for patients receiving azithromycin monotherapy vs 2.84 days for those receiving ATS antibiotics (P =.008) and 2.58 days for those receiving non-ATS antibiotics (P =.64). Overall mean length of stay was shorter in the azithromycin monotherapy group (4.35 days) vs the ATS (5.73 days) (P =.002) and non-ATS (6.21 days) (P<.001) groups. Mortality, intensive care unit transfer, and readmission rates were similar across the groups. CONCLUSION: Azithromycin monotherapy is equally as efficacious as other ATS-recommended regimens for treating hospitalized patients with mild-to-moderate community-acquired pneumonia.
