The incidence of healthcare-associated infections and sepsis (HAIs) is 5-10 times higher in patients in intensive care units (ICUs) than in those at other hospital departments. Predisposition for these lies in many intrinsic (disease severity, loss of immunity) and extrinsic factors (frequent use of broad-spectrum antibiotics with consequent presence of antibiotic-resistant pathogens). The majority of HAIs in ICUs are associated with the use of invasive devices (DA-HAIs; device-associated healthcare-associated infections) (19%). Their incidence differs among specific types of ICUs (2%-49%). The most frequent DA-HAI are central line-associated bloodstream infections (CLA-BSI), ventilator-associated pneumonia (VAP), catheter-associated urinary tract infection (CAUTI) and surgical site infections (SSI). SSI is most often described as a distinct and separate entity of HAIs in ICUs. Recently, gram-negative bacilli (Pseudomonas aeruginosa, Klebsiella pneumoniae and Acinetobacter spp.) are more frequently isolated in DA-HAIs than gram-positive ones (Staphylococcus aureus, Enterococcus spp.), often present as resistant strains. On the other hand, urinary or/and systemic infections tend to increase. DA-HAIs endanger and slow down patient recovery, prolong hospital stay, and generally increase the mortality rate. DA-HAIs are of special interest of the Hospital Committee Center for Infective Disease in order to improve patient safety and reduce total cost allocated for prevention of DA-HAIs. DA-HAI rate is the most useful intra- and inter-hospital measure to compare surveillance and effectiveness of preventive procedures among different ICU types.
重症监护病房(ICU)患者发生医疗保健相关感染和脓毒症(HAIs)的几率比其他医院科室的患者高5至10倍。这些感染的易感性存在于许多内在因素(疾病严重程度、免疫力丧失)和外在因素(频繁使用广谱抗生素以及随之出现的抗生素耐药病原体)之中。ICU中大多数HAIs与侵入性设备的使用有关(器械相关医疗保健相关感染;DA-HAIs)(19%)。其发生率在特定类型的ICU之间有所不同(2%-49%)。最常见的DA-HAI是中心静脉导管相关血流感染(CLA-BSI)、呼吸机相关性肺炎(VAP)、导尿管相关尿路感染(CAUTI)和手术部位感染(SSI)。SSI在ICU中最常被描述为HAIs的一个独特且独立的实体。最近,在DA-HAIs中分离出革兰氏阴性杆菌(铜绿假单胞菌、肺炎克雷伯菌和不动杆菌属)的频率高于革兰氏阳性菌(金黄色葡萄球菌、肠球菌属),且常表现为耐药菌株。另一方面,泌尿系统或/和全身感染有增加的趋势。DA-HAIs危及患者康复并使其减慢,延长住院时间,总体上还会增加死亡率。为了提高患者安全性并降低预防DA-HAIs的总成本,医院感染病委员会中心对DA-HAIs特别关注。DA-HAI发生率是比较不同类型ICU之间监测情况和预防措施有效性的最有用的院内和院间指标。
