“…21 Socioeconomic factors are associated with lower rates of survival within 1 hour after birth among periviable infants, likely owing to differences in providing resuscitation. 27 We found multiple socioeconomic differences by race/ethnicity, but it is unknown whether these influenced clinical decision-making.…”

IMPORTANCE Racial/ethnic disparities in quality of care among extremely preterm infants are associated with adverse outcomes. OBJECTIVE To assess whether racial/ethnic disparities in major outcomes and key care practices were changing over time among extremely preterm infants. DESIGN, SETTING, AND PARTICIPANTS This observational cohort study used prospectively collected data from 25 US academic medical centers. Participants included 20 092 infants of 22 to 27 weeks' gestation with a birth weight of 401 to 1500 g born at centers participating in the National

“…Rates of neonatal survival at 22 weeks' gestation range from 0.7% in France 1 to 2.0% in the United Kingdom, 2 5.1% in the United States, 3 9.8% in Sweden, 4 and 33.1% in Japan. 5 This wide range persists at 23 weeks' (1%-52%) and 24 weeks' (31%-67%) gestation. 6 Up-to-date relevant and gestationspecific survival rates are required for evidence-based counseling and decision-making.…”

“…6,12 In this study, we explore international differences in the classification of births at 22 to 25 weeks' gestation as antepartum or intrapartum stillbirths or neonatal deaths and the subsequent impact of these differences on neonatal survival rates. We use data from 7 high-income countries, including 2 countries (Japan 5,13 and Sweden 4 ) that have reported considerably higher rates of survival at periviable gestational ages.…”

“…12 In Japan, there is recognition that socioeconomic status can affect resuscitation practices between 22 and 24 weeks of gestation; however, the national definition accommodates for the earliest possible survival age at 22 weeks. 40,84 Advancements in newborn care in China have improved survival of babies born between 25 and 27 weeks in regions with more advanced health care available; however, the official, national viability threshold remains 28 weeks. 85 This highlights the need for definitions to be regularly reviewed in light of advancements in perinatal care.…”

Preterm birth and stillbirth are important global perinatal health indicators. Definitions of these indicators can differ between countries, affecting comparability of preterm birth and stillbirth rates across countries. This study aimed to document national-level adherence to World Health Organization (WHO) definitions of preterm birth and stillbirth in the WHO Western Pacific region. A systematic search of government health websites and 4 electronic databases was conducted. Any official report or published study describing the national definition of preterm birth or stillbirth published between 2000 and 2020 was eligible for inclusion. A total of 58 data sources from 21 countries were identified. There was considerable variation in how preterm birth and stillbirth was defined across the region. The most frequently used lower gestational age threshold for viability of preterm birth was 28 weeks gestation (range 20-28 weeks), and stillbirth was most frequently classified from 20 weeks gestation (range 12-28 weeks). High-income countries more frequently used earlier gestational ages for preterm birth and stillbirth compared with low- to middle-income countries. The findings highlight the importance of clear, standardized, internationally comparable definitions for perinatal indicators. Further research is needed to determine the impact on regional preterm birth and stillbirth rates.

Socioeconomic inequity in survival for deliveries at 22–24 weeks of gestation

Abstract: Socioeconomic factors substantially influence whether births of 22-24 weeks' GA survive delivery and the first hour of life. Such disparities may reflect the impact of socioeconomic situations on decision making for resuscitation.
