Abstract
INTRODUCTION: Preterm birth-related complications are the leading cause of under-5 mortality globally. Bhutan does not have a reliable preterm birth rate or data regarding outcome of preterm babies. AIM: To determine the preterm birth rate at the Jigme Dorji Wangchuck National Referral Hospital (JDWNRH) in Thimphu, Bhutan, and assess their outcomes. METHODS: All live preterm births at JDWNRH from 1 January 2017 to 31 December 2017 were followed from birth till hospital discharge. Maternal demographic data, pregnancy details and delivery details were collected. Morbidity and mortality information as well as discharge outcome were collected on babies admitted to neonatal intensive care unit (NICU). RESULTS: Preterm birth rate among live births was 6.4%. Most mothers were younger than 30 years, housewives and had secondary education. Pregnancy registration rate and adequacy of antenatal visits were high. Most preterm births were singleton and the predominant mode of delivery was cesarean section. More than half of the births were initiated spontaneously, and the male:female ratio was 1.2:1. Most babies were late preterm and low birth weight. Half of them required NICU admission. Overall mortality rate was 11% and 21.6% for admitted preterm neonates. Preterm small-for-gestational-age neonates, and those born after provider-initiated preterm birth had significantly increased risk of mortality. Most preterm neonates were discharged without complications. The rate of extrauterine growth restriction was high. CONCLUSION: This is the first study on the prevalence of preterm births and their outcomes in the largest tertiary-care hospital in Bhutan.
