不到一半的患者通过痰和血液培养以及尿液中肺炎链球菌和嗜肺军团菌抗原检测来确定社区获得性肺炎 (CAP) 的病因。这项研究添加了针对肺炎链球菌、金黄色葡萄球菌和呼吸道病毒的鼻聚合酶链反应 (PCR) 探针。测量血清降钙素原(PCT)水平。 78% 的患者中发现了病原体。为了检测病毒,患者被随机分配使用 5 种病毒实验室生成的 PCR 包或 17 种病毒 FilmArray PCR 平台。 FilmArray PCR 平台检测到的病毒数量比实验室生成的病毒包还要多,并且在不到 2 小时的时间内完成检测。病毒感染且血清 PCT 水平较低的 CAP 患者抗生素治疗天数较少,P = 0.003。检测 85% 患者的潜在 CAP 病因 2 小时内提供可操作的治疗数据 需要提供者教育
The etiology of community-acquired pneumonia (CAP) is determined in less than half of the patients based on cultures of sputum and blood plus testing urine for the antigens of Streptococcus pneumoniae and Legionella pneumophila. This study added nasal polymerase chain reaction (PCR) probes for S. pneumoniae, Staphylococcus aureus, and respiratory viruses. Serum procalcitonin (PCT) levels were measured. Pathogens were identified in 78% of the patients. For detection of viruses, patients were randomized to either a 5-virus laboratory-generated PCR bundle or the 17-virus FilmArray PCR platform. The FilmArray PCR platform detected more viruses than the laboratory-generated bundle and did so in less than 2 hours. There were fewer days of antibiotic therapy, P = 0.003, in CAP patients with viral infections and a low serum PCT levels. Detection of potential CAP etiology in 85% of patients Actionable treatment data within 2 hours Need for provider education
