The aim is to determine the prevalence of bacterial nosocomial infections (NI) and its associated factors in COVID-19 ICU.
A descriptive retrospective study, from April to August 2020, was carried on patients with respiratory distress following SARS-Cov-2 infection presenting a sign of bacterial infection.
A total of 29 patients (33% of hospitalized patients) contracted a NI, their age was 65 years ± 13.90 and sex-ratio M/F was 2.62. All patients had an invasive device: central line (65%), bladder catheter (72%), and mechanical ventilation (76%). The time of NI occurring was 5 to 8 days. Charlson comorbidity index was 4 - 6 in 18 patients (62%). Of the 35 samples taken, 45 bacteria were isolated: multi drug resistant A. baumannii and P. aeruginosa accounted for 24.4%. Of all, 16 deaths were recorded (55, 17%).
NI is common in COVID-19 ICU and can be predicted by risk factors that should be managed.
目的是确定 COVID-19 ICU 中细菌医院感染（NI）的流行情况及其相关因素。
这是一项描述性回顾性研究，于 2020 年 4 月至 8 月进行，研究对象为因 SARS-CoV-2 感染出现呼吸道窘迫并表现出细菌感染迹象的患者。
共有 29 名（住院患者的 33%）患者发生 NI，其年龄为 65 岁±13.90 岁，男女比例为 2.62。所有患者均有侵入性器械：中心静脉置管（65%）、导尿管（72%）和机械通气（76%）。NI 发生时间为 5 至 8 天。18 名患者（62%）的 Charlson 合并症指数为 4-6。在 35 个样本中分离出 45 株细菌：耐多药鲍曼不动杆菌和铜绿假单胞菌占 24.4%。总共有 16 例死亡（55%，17%）。
NI 在 COVID-19 ICU 中很常见，可以通过应加以管理的危险因素进行预测。
