Sepsis is a leading cause of neonatal mortality in low-resource settings. As facility-based births become more common, the proportion of neonatal deaths due to hospital-onset sepsis has increased.
We conducted a prospective cohort study in a neonatal intensive care unit in Zambia where we implemented a multifaceted infection prevention and control (IPC) bundle consisting of IPC training, text message reminders, alcohol hand rub, enhanced environmental cleaning, and weekly bathing of babies ≥1.5 kg with 2% chlorhexidine gluconate. Hospital-associated sepsis, bloodstream infection (BSI), and mortality (>3 days after admission) outcome data were collected for 6 months prior to and 11 months after bundle implementation.
Most enrolled neonates had a birth weight ≥1.5 kg (2131/2669 [79.8%]). Hospital-associated mortality was lower during the intervention than baseline period (18.0% vs 23.6%, respectively). Total mortality was lower in the intervention than prior periods. Half of enrolled neonates (50.4%) had suspected sepsis; 40.8% of cultures were positive. Most positive blood cultures yielded a pathogen (409/549 [74.5%]), predominantly Klebsiella pneumoniae (289/409 [70.1%]). The monthly rate and incidence density rate of suspected sepsis were lower in the intervention period for all birth weight categories, except babies weighing <1.0 kg. The rate of BSI with pathogen was also lower in the intervention than baseline period.
A simple IPC bundle can reduce sepsis and death in neonates hospitalized in high-risk, low-resource settings. Further research is needed to validate these findings in similar settings and to identify optimal implementation strategies for improvement and sustainability.

在资源匮乏地区,脓毒症是新生儿死亡的主要原因。随着设施分娩日益普遍,医院获得性脓毒症导致的新生儿死亡比例有所增加。
我们在赞比亚的一家新生儿重症监护病房开展了一项前瞻性队列研究,在该研究中实施了多方面的感染预防与控制(IPC)综合措施,包括IPC培训、短信提醒、酒精擦手、强化环境清洁以及每周用2%葡萄糖酸氯己定给体重≥1.5千克的婴儿洗澡。收集了综合措施实施前6个月和实施后11个月的医院相关脓毒症、血流感染(BSI)以及死亡率(入院3天后)结局数据。
大多数纳入研究的新生儿出生体重≥1.5千克(2131/2669 [79.8%])。干预期间的医院相关死亡率低于基线期(分别为18.0%和23.6%)。干预期间的总死亡率低于之前各时期。一半的纳入研究新生儿(50.4%)疑似患有脓毒症;40.8%的培养结果呈阳性。大多数血培养阳性结果检出了病原体(409/549 [74.5%]),主要是肺炎克雷伯菌(289/409 [70.1%])。除体重<1.0千克的婴儿外,所有出生体重类别在干预期的疑似脓毒症月发生率和发病密度率均较低。干预期病原体导致的BSI发生率也低于基线期。
一项简单的IPC综合措施可降低高危、资源匮乏环境中住院新生儿的脓毒症和死亡率。需要进一步研究以在类似环境中验证这些发现,并确定改善和可持续性的最佳实施策略。
