Clinical manifestations and risk factors of community-onset Acinetobacter species pneumonia in Japan; case control study in a single institute in Japan

摘要

To clarify the etiology, patients' characteristics and risk factors for community-onset AP (Acinetobacter species pneumonia), we conducted this case-control study. We reviewed all patients with community-onset AP at our institute from 2010 until 2018. We defined non-AP group as a control. The patients with non-Acinetobacter spp. pneumonia (non-AP) were randomly selected during the study period without clinical information based on medical records' list among patients with community-onset pneumonia. The age (+/- 2 years) and sex were matched to the patients with community-onset AP, and the ratio was AP: non-AP group = 1: 3. Patients' characteristics, clinical outcomes, pathogens isolated and drug susceptibility were evaluated by comparing AP and non-AP group.
