BACKGROUND: Large numbers of preterm infants are born in middle-income countries and neonatal care is improving in these countries. Few studies have compared clinical outcome in preterm infants in a tertiary neonatal unit in a middle-income country with one in a high-income country.
OBJECTIVE: To compare the short-term outcome in preterm infants of ≤30 weeks gestation admitted to a tertiary neonatal unit in Bengaluru, India and in London, UK.
METHODS: This was a retrospective observational study using anonymised data from electronic patient records. Preterm infants born at ≤30 weeks gestation admitted to neonatal units in Bengaluru (n = 294) and London (n = 740) over a 5-year period (January 2011 to December 2015) were compared.
RESULTS: Fewer mothers in the Bengaluru centre received antenatal steroids (37% vs 73%, p < 0.001). The incidence of retinopathy of prematurity requiring treatment (12.9% vs 7.7%, NS), treated patent ductus arteriosus (32.3% vs 10.7%, NS) and blood culture-positive sepsis (32.4% vs 1.7%, p < 0.001) was higher in infants in the Indian centre. Overall survival was 83% vs 87.2% (NS) in the Bengaluru and the London cohorts, respectively. Survival of infants born at ≤28 weeks gestation was lower in Bengaluru than in London [24 weeks: 33.0% vs 79.3% (NS); 25 weeks: 50.0% vs 78.9%, p = 0.02; 26 weeks: 45.2% vs 86.5%, p < 0.01; 27 weeks: 79.3% vs 91.3% (NS); 28 weeks 82.5% vs 94.1%, p = 0.03].
CONCLUSION: The survival of infants ≤28 weeks gestation was significantly lower in the Bengaluru centre. Increasing the provision of antenatal corticosteroids may improve the outcome in these infants.
