在这个前瞻性研究,作者评估了发病率、病因学,结果在普通人群中社区获得性肺炎患者。从1993年12月到1995年11月,一项研究在混合residential-industrial执行“Maresme”地区的城市人口在巴塞罗那,西班牙。所有科目> = 14岁的年龄(年平均人口规模74368居民)和临床疑似肺炎被注册。所有情况下被胸片的第五天重新评估疾病和在每月的间隔,直到完全恢复。尿液和血液样本获得文化和抗原检测。下呼吸道分泌物获得时,这些也讲究的。有241例社区获得性肺炎,每年的发病率为1.62情况下(95%置信区间,1.42 - -1.82)每1000名居民。发病率增加了年龄,男性比女性高。232患者病原学的数据,104年有一个可识别的病因学。共有114个病原体被发现(94年单一病原体,两个病原体10)。 There were 81 episodes of bacterial infection and 33 of viral infection. The most common pathogens were Streptococcus pneumoniae, Chlamydia pneumoniae, and influenza A and B viruses. No case of Hantavirus infection was found. The rate of hospital admission was 61.4% with a mean+/-SD length of 11.7+/-10.1 days, a mean period of 23.0+/-14.3 days inactivity, and an overall mortality rate of 5%. The high rate of hospital admission, prolonged stay in hospital, and long period of inactivity all continue to constitute a social and health care burden of community-acquired pneumonia.
