在美国研究社区获得性肺炎的患者年龄在65年表明,革兰氏阴性杆菌占相当大比例的情况下,除了通常的病原体肺炎链球菌和流感嗜血杆菌等。没有报道称,英国老年人社区获得性肺炎。我们进行了这样一项研究以确定临床特征、病因学,结果。七十三例(38人)从65年到97年,年龄(平均79)年前瞻性研究。肺炎被定义为急性下呼吸道感染新的,以前没有记录的阴影在胸部x光照片。严重的慢性疾病患者肺炎是一个预期的终端事件被排除在外。几乎所有的患者(96%)有呼吸道症状或体征,但许多功能可能会掩盖真正的诊断肺炎。超过一半的患者non-respiratory症状和超过三分之一没有系统性感染的迹象。病原体被发现在43%的患者中,最常见的肺炎链球菌,流感嗜血杆菌和乙型流感病毒。革兰氏阴性杆菌没有见过。 The mortality rate was high (33%). Early deaths were due to infection whereas later deaths were associated with other factors, such as stroke (two patients) and pulmonary embolism (two patients). Prognostic indicators for mortality were apyrexia, systolic hypotension, increasing hypoxaemia, and new urinary incontinence. As the range of pathogens causing pneumonia was the same in the elderly in this study as in other age groups it is suggested that initial antibiotic treatment for patients in this age group should always cover S pneumoniae and H influenzae.
