Hospital-born babies in developing countries are at increased risk of neonatal infections because of poor intrapartum and postnatal infection-control practices. We reviewed data from developing countries on rates of neonatal infections among hospital-born babies, range of pathogens, antimicrobial resistance, and infection-control interventions. Reported rates of neonatal infections were 3-20 times higher than those reported for hospital-born babies in industrialised countries. Klebsiella pneumoniae, other gram-negative rods (Escherichia coli, Pseudomonas spp, Acinetobacter spp), and Staphylococcus aureus were the major pathogens among 11,471 bloodstream isolates reported. These infections can often present soon after birth. About 70% would not be covered by an empiric regimen of ampicillin and gentamicin, and many might be untreatable in resource-constrained environments. The associated morbidity, mortality, costs, and adverse effect on future health-seeking behaviour by communities pose barriers to improvement of neonatal outcomes in developing countries. Low-cost, "bundled" interventions using systems quality improvement approaches for improved infection control are possible, but should be supported by evidence in developing country settings.
由于产时和产后感染控制措施不力,发展中国家在医院出生的婴儿发生新生儿感染的风险增加。我们回顾了发展中国家有关医院出生婴儿的新生儿感染率、病原体种类、抗菌药物耐药性及感染控制干预措施的数据。报告的新生儿感染率比工业化国家医院出生婴儿的感染率高3至20倍。在报告的11471例血流感染分离株中,肺炎克雷伯菌、其他革兰氏阴性杆菌(大肠杆菌、假单胞菌属、不动杆菌属)及金黄色葡萄球菌是主要病原体。这些感染常在出生后不久出现。约70%的感染不能被氨苄西林和庆大霉素的经验性治疗方案覆盖,在资源有限的环境中许多感染可能无法治疗。相关的发病率、死亡率、成本以及对社区未来就医行为的不利影响,对改善发展中国家新生儿结局构成了障碍。采用系统质量改进方法进行低成本的“捆绑式”干预以改善感染控制是可行的,但应有发展中国家背景下的证据支持。
