Global study reveals wide gaps in infant sepsis prevention across wealthy nations
A 10-country analysis found late-onset sepsis rates in extremely premature infants vary dramatically—from 7% in Japan to 45% in Spain—suggesting that proven prevention strategies aren't being applied uniformly. The findings signal both an opportunity for policy makers to adopt best practices and a challenge for hospitals facing preventable infections that drive costs and mortality.
Originaltitel: Late-onset sepsis among extremely preterm infants of 24-28 weeks gestation: an international comparison in 10 high-income countries
<p>Introduction: Despite advances in neonatal care, late-onset sepsis remains an important cause of preventable morbidity and mortality. Neonatal late-onset sepsis rates have decreased in some countries, while in others they have not. Our objective was to compare trends in late-onset sepsis rates in 9 population-based networks from 10 countries and to assess the associated mortality within 7 days of late-onset sepsis.</p><p>Methods: We performed a retrospective populationbased cohort study. Infants born at 24-28 weeks' gestation between 2007 and 2019 were eligible for inclusion. Lateonset sepsis was defined as a positive blood or cerebrospinal fluid culture. Late-onset sepsis rates were calculated for 3 epochs (2007-11, 2012-15, and 2016-19). Adjusted risk ratios (aRRs) for late-onset sepsis were calculated for each network.</p><p>Results: Of a total of 82,850 infants, 16,914 (20.4%) had late-onset sepsis, with Japan having the lowest rate (7.1%) and Spain the highest (44.6%). Late-onset sepsis rates decreased in most networks and remained unchanged in a few. Israel, Sweden, and Finland showed the largest decrease in late-onset sepsis rates. The aRRs for late-onset sepsis showed wide variations between networks. The rate of mortality temporally related to late-onset sepsis was 10.9%. The adjusted mean length of stay for infants with late-onset sepsis was increased by 5-18 days compared to infants with no late-onset sepsis.</p><p>Conclusions: One in 5 neonates of 24-28 weeks' gestation develops late-onset sepsis. Wide variability in late-onset sepsis rates exists between networks with most networks exhibiting improvement. Late-onset sepsis was associated with increased mortality and length of stay.</p>
