Rates of rehospitalisation in the first two years among preterm infants discharged from the NICU of a tertiary children hospital in Vietnam – A follow-up study

Objectives To describe the characteristics of rehospitalisation in Vietnamese preterm infants, and to examine the time-to-first-readmission between two gestational age (GA) groups (extremely/very preterm, EVP, versus moderate/late preterm, MLP). Further, to compare rehospitalisation rates according to GA and corrected age (CA), and to examine the association between potential risk factors and rehospitalisation rates.

Design and Setting Cohort study to follow up preterm infants discharged from a neonatal intensive care unit (NICU) of a tertiary children’s hospital in Vietnam.

Participants All preterm newborns admitted to the NICU from July 2013 to September 2014.            

Main outcomes Rates, durations and causes of hospital admission during the first two years. 

Results Of 294 preterm infants admitted to NICU (all out-born, GA ranged from 26 to 36 weeks), 255 were discharged alive, and 211 (83%) NICU graduates were followed up at least once during the first two years CA, ...

研究目的 旨在描述越南早产儿再住院的特征，并对比极早早产/极早产（extremely/very preterm, EVP）与中度/晚期早产（moderate/late preterm, MLP）两组患儿的首次再住院时间间隔。此外，本研究还将依据胎龄（gestational age, GA）与矫正胎龄（corrected age, CA）比较再住院率，并探究潜在危险因素与再住院率之间的关联。
研究设计与研究场景 本研究为队列研究，对越南某三级儿童医院新生儿重症监护病房（neonatal intensive care unit, NICU）出院的早产儿开展随访。
研究对象 2013年7月至2014年9月期间收入该新生儿重症监护病房的所有早产新生儿。
主要结局指标 患儿出生后前两年内的住院发生率、住院时长及住院病因。
研究结果 本研究共纳入294例收入新生儿重症监护病房的早产新生儿（均为院外分娩，胎龄范围为26至36周），其中255例存活出院；211例（占比83%）NICU存活出院患儿在矫正胎龄后的前两年内至少接受过1次随访，
