Clinical and microbiological description of bacteremias seen in 13 regional hospitals of Barcelona.
From January to December of 1991 a multicenter prospective study of bacteremia in regional hospitals was performed. The filiation, clinical findings and microbiological results were registered according to a common protocol.
We studied 1674 episodes of bacteremia (13.8 per 1000 admissions). Patients were distributed into 3 groups according to age: under 14: 204 patients, between 14 to 65: 759 and over 65: 711 patients. Men account for 55% and women for 45% of episodes. The bacteremia was hospital-acquired in 24.4% of cases. The most common foci of infection were: urinary tract (32%), respiratory tract (14%), intestinal tract (8%), intravascular catheter (7%), biliary tract (7%) and unknown (10%). The most commonly isolated strains were: Escherichia coli 544 cases, Streptococcus pneumoniae 212, Staphylococcus aureus 139, coagulase negative staphylococi 85, Non-typhoid Salmonella 66, Neisseria meningitidis 63, Pseudomonas sp. 59, Enterococcus sp. 59 and Bacteroides sp. 58. Polimicrobial bacteremia was detected in 83 episodes (5%). Related mortality rate was 9.6% (161 patients).
巴塞罗那13家地区医院菌血症的临床及微生物学描述。
1991年1月至12月，在地区医院开展了一项关于菌血症的多中心前瞻性研究。按照通用方案记录谱系、临床发现及微生物学结果。
我们研究了1674例菌血症病例（每1000例入院患者中有13.8例）。患者按年龄分为3组：14岁以下：204例患者；14至65岁：759例；65岁以上：711例。菌血症发作病例中男性占55%，女性占45%。24.4%的病例菌血症为医院获得性。最常见的感染部位为：泌尿系统（32%）、呼吸道（14%）、肠道（8%）、血管内导管（7%）、胆道（7%）及不明部位（10%）。最常分离出的菌株为：大肠杆菌544例、肺炎链球菌212例、金黄色葡萄球菌139例、凝固酶阴性葡萄球菌85例、非伤寒沙门菌66例、脑膜炎奈瑟菌63例、假单胞菌属59例、肠球菌属59例及拟杆菌属58例。83例（5%）检测到多菌型菌血症。相关死亡率为9.6%（161例患者）。
