This study aimed to describe the prevalence, clinical characteristics and outcomes of bacteraemia caused by species at a university hospital in Oman.
This observational retrospective study was conducted over a 5-year period from 2015 to 2019 at Sultan Qaboos University Hospital, Muscat, Oman. Adult patients (18 years and above) with bacteraemia caused by species were included. Data were collected retrospectively from the hospital information system using a standardised data collection form.
A total of 142 cases of bacteraemia were observed, with being isolated in the majority of cases (n = 88, 62%) compared to (n = 40, 28.2%); 83 (58.5%) cases were identified as nosocomial bacteraemia. The incidence of infection was higher among males (n = 96, 67.6%) than females (n = 46, 32.4%). There were 43 cases of polymicrobial bacteraemia along with species. Indwelling bladder catheter, ventilation and central venous catheters were identified as significant predisposing factors for bacteraemia. The 30-day mortality rate was 32% (n = 28 among and 45% (n = 18 among bacteraemia patients. Infective endocarditis was observed in 8 (5.6%) patients, with being isolated in 6 (4.2%) of them. Echo findings showed tricuspid valve involvement as the most involved valve.
This study showed that and were the most common species isolated. A high proportion of isolates were resistant to ampicillin and vancomycin. bacteraemia remains a significant cause of healthcare-associated infections.
本研究旨在描述阿曼一家大学医院中由[具体菌种]引起的菌血症的患病率、临床特征及转归。
这项观察性回顾性研究于2015年至2019年在阿曼马斯喀特的苏丹卡布斯大学医院进行，为期5年。纳入由[具体菌种]引起菌血症的成年患者（18岁及以上）。使用标准化数据收集表从医院信息系统中回顾性收集数据。
共观察到142例菌血症病例，其中大多数病例分离出[具体菌种]（n = 88，62%），相比之下[另一种菌种]为（n = 40，28.2%）；83例（58.5%）病例被确定为医院获得性菌血症。男性感染发生率（n = 96，67.6%）高于女性（n = 46，32.4%）。有43例多重微生物菌血症合并[具体菌种]。留置膀胱导管、通气和中心静脉导管被确定为菌血症的重要易感因素。30天死亡率为32%（菌血症患者中n = 28），[另一种菌血症类型]为45%（n = 18）。8例（5.6%）患者观察到感染性心内膜炎，其中6例（4.2%）分离出[具体菌种]。超声心动图结果显示三尖瓣受累是最常受累的瓣膜。
本研究表明，[具体菌种]和[另一种菌种]是分离出的最常见的[菌种类型]。很大一部分[具体菌种]分离株对氨苄西林和万古霉素耐药。[具体菌种]菌血症仍然是医疗相关感染的重要原因。
