BackgroundPreterm infants are at risk of neurodevelopmental delay, but data on long-term outcomes in low-income and middle-income countries remain scarce.ObjectivesTo examine neurodevelopment using Bayley Scales of Infant and Toddler Development-3rd edition (Bayley-III) and neurological findings in 2-year-old preterm infants, and to compare with healthy Vietnamese infants. Further, to assess factors associated with neurodevelopmental impairment.Design and settingCohort study to follow up preterm infants discharged from a neonatal intensive care unit (NICU) of a tertiary children’s hospital in Vietnam.ParticipantsInfants born at <37 weeks of gestational age.Main outcomesBayley-III assessment and neurological examination at 2-year corrected age (CA) compared with healthy Vietnamese infants.ResultsOf 294 NICU preterm infants, Bayley-III scores of all 184/243 (76%) survivors at 2 years CA were significantly lower than those of healthy Vietnamese peers in all three domains: cognition (mean (SD): 84.5 (8.6) vs 91.4 (7.5), p<0.001), language (mean (SD): 88.7 (12.5) vs 95.9 (11.9), p<0.001) and motor (mean (SD): 93.1 (9.0) vs 96.8 (9.3), p=0.003). The mean differences in Bayley-III scores between preterm and healthy Vietnamese infants were −6.9 (−9.1 to −4.7), −7.2 (−10.5 to −3.8) and −3.7 (−6.1 to −1.2) for cognitive, language and motor scores, respectively. The prevalence of neurodevelopmental impairment was 17% for cognitive, 8% for language and 4% for motor performance. In total, 7% were diagnosed with cerebral palsy. Higher maternal education was positively associated with infant neurodevelopment (OR 0.32, 95% CI 0.11 to 0.94).ConclusionsVietnamese preterm infants in need of neonatal intensive care showed poor neurodevelopment at 2 years. Higher maternal education was positively associated with infant neurodevelopment. Standard follow-up programmes for preterm infants should be considered in low-resource settings.

Septicemia and bloodstream infections (BSIs) are major causes of neonatal morbidity and mortality in developing countries. We prospectively recorded all positive blood cultures (BSI) among neonates admitted consecutively to a tertiary pediatric hospital in Vietnam during a 12-month period. Among 5763 neonates, 2202 blood cultures were performed, of which 399 were positive in 385 neonates. Among these, 64 died, 62 in relation to septicemia. Of the BSI isolates, 56% was known pathogenic and 48% was gram-negative bacteria, most frequently Klebsiella spp. (n = 78), Acinetobacter spp. (n = 58) and Escherichia coli (n = 21). Only three Streptococcus spp. were identified, none group B. Resistance against antibiotics applied was common. The mortality was highest in neonates with gram-negative BSI compared with no confirmed BSI and gram-positive BSI (P < 0.01). In this setting, the majority of BSI were likely to have been transmitted from the environment. Improvement of hygienic precautions and systematic BSI surveillance are recommended.
