Aim: To evaluate the associations between type of light-emitting diode phototherapy intervention and hospital and patient related outcomes in term neonates with non-haemolytic jaundice.
Methods: A retrospective observational study in a community hospital within a disadvantaged area in Australia was conducted. Data was extracted from hospital systems and medical records regarding the use of three types of phototherapy surface-area exposure for term neonates ≤28 days with non-haemolytic neonatal jaundice. Associations between type of phototherapy management and length of stay (LOS), rate of serum bilirubin (SBR) decline and duration of phototherapy were estimated using the general linear mixed model or linear regression.
Results: Of 102 neonates diagnosed with non-haemolytic jaundice between 1 June 2016 and 31 August 2017, 82 were included in final analyses. Neonates treated for jaundice during their first (birth) admission had a median LOS of 118 h for single-sided and 125 h for maximal double-sided phototherapy. Differences by phototherapy type were not statistically significant (P = 0.06). SBR rate of decline increased as surface-area of phototherapy increased (P < 0.001) with the fastest decline seen in maximal double-sided phototherapy. Estimated duration of phototherapy did not vary by phototherapy type but did vary by age at initiation of phototherapy (P = 0.006), with 16 fewer hours of phototherapy if commenced at ≥72 to <96 h versus ≥24 to 48 h of age (difference -16.4 h, 95% confidence interval -29.1 to -3.7 h).
Conclusions: LOS and phototherapy duration were not associated with phototherapy type. Older neonates with neonatal jaundice required shorter phototherapy duration. Double-sided phototherapy was associated with faster reduction in SBR.
