Abstract

Aim: Very premature infants consume healthcare resources following discharge from neonatal intensive care units (NICU). This study aimed to evaluate the burden of respiratory related rehospitalisation within the first 3 years post discharge in very premature infants in an Australian population. Methods: Rehospitalisation of a 4-year cohort of NICU survivors, born less than 32 weeks gestation, was derived from data linkage of three state-wide databases including NSW Neonatal Intensive Care Units' Data Collection, Admitted Patient Data Collection and the Death Registry. Rehospitalisation diagnoses were determined by ICD-10 AM codes. Results: Of the 2939 survivors, 525 (18%) had bronchopulmonary dysplasia (BPD) and 261 BPD infants (50%) were discharged on home oxygen. Almost two-third (1860, 63%) of the survivors are required rehospitalisation, respiratory causes, including 394 respiratory syncytial virus (RSV)-related, accounted for 2668 (48%) of the 5599 rehospitalisations. Significantly more home oxygen BPD survivors had respiratory (70%) and RSV-related (22%) rehospitalisations than the BPD infants not needing home oxygen (58% and 18%, respectively), and the survivors without BPD had the lowest rates (32% and 10%, P < 0.001). Most respiratory (61%) and RSV-related (74%) rehospitalisations occurred during the first 12 months post discharge. No RSV-related fatality occurred. Amongst the total 17 562 hospital days, respiratory and RSV-related admissions accounted for 10 905 (62%) and 3031 (17.2%) days. In multivariable logistic analyses, home oxygen and maternal indigenous status were independently associated with high (3 or more) respiratory and RSV rehospitalisation rates. Conclusions: Respiratory rehospitalisations are common in very premature survivors. Home oxygen and indigenous status are significant risk factors for respiratory and RSV-related rehospitalisations.
