我们的目的是确定社区获得性肺炎中与胸腔积液相关的发病率、临床后果和微生物学结果，并确定脓胸/复杂肺炎旁胸腔积液的预测因素。我们连续分析了来自两家急症护理医院的 4,715 名社区获得性肺炎患者。患者被分为三组：无胸腔积液、单纯性肺炎旁胸腔积液和脓胸/复杂性肺炎旁胸腔积液。共有 882 名患者（19%）有胸腔积液的放射学证据，其中 261 名患者（30%）符合脓胸/复杂性肺炎旁胸腔积液的标准。与单纯性肺炎旁胸腔积液的存在相关的最重要事件是住院时间延长。相关的临床和微生物学后果与脓胸/复杂性肺炎旁胸腔积液有关。五个独立的基线特征可以预测脓胸/复杂性肺炎旁胸腔积液的发展：年龄100次.min(-1) (p=0.006)和白细胞增多>15,000 mm(-3) (p
We aimed to determine the incidence, clinical consequences and microbiological findings related to the presence of pleural effusion in community-acquired pneumonia, and to identify predictive factors for empyema/complicated parapneumonic effusion. We analysed 4,715 consecutive patients with community-acquired pneumonia from two acute care hospitals. Patients were classified into three groups: no pleural effusion, uncomplicated parapneumonic effusion and empyema/complicated parapneumonic effusion. A total of 882 (19%) patients had radiological evidence of pleural fluid, of whom 261 (30%) met criteria for empyema/complicated parapneumonic effusion. The most important event related to the presence of uncomplicated parapneumonic effusion was a longer hospital stay. Relevant clinical and microbiological consequences were associated with empyema/complicated parapneumonic effusion. Five independent baseline characteristics could predict the development of empyema/complicated parapneumonic effusion: age 100 beats.min(-1) (p=0.006) and leukocytosis >15,000 mm(-3) (p
