Objectives: To examine parental participation in the care of newborn infants receiving therapeutic hypothermia, and to explore the possible impact of in-born vs out-born status, and location of hospital accommodation. Study design: Retrospective, quantitative and descriptive design. Main outcome measures: Infants medical charts were reviewed for defined aspects of parental participation (infant holding, tube feeding, and diaper change), and related to their in-born vs out-born status, and whether the parents were accommodated in the NICU or elsewhere. All infants have been cared for at the University Hospital Neonatal Intensive Care Unit, serving as a regional referral center for hypothermia treatment. This study is a part of a population-based regional cohort of asphyxiated newborn infants (n = 112) that received therapeutic hypothermia in 2007-2015. Results: Parents engaged in holding (60/112, 54%) or tube feeding (59/112, 53%) their infant. Parents of inborn infants (24/112, 21%) were more likely to check the placement of the feeding tube (11/24, 46% vs 15/88, 17%; p < 0.01) and change diapers (9/24, 38% vs 14/88, 16%; p < 0.05) than parents of out-born infants (88/112, 79%). A similar pattern of more extensive involvement was observed for both mothers and fathers who stayed at the neonatal intensive care compared to those accommodated elsewhere (p < 0.05). Conclusions: Active parental participation is feasible at the NICU even during therapeutic hypothermia. Timely postnatal transfer of parents of out-born/transported infants, and the provision of on-site accommodation may influence the quality of parental involvement.
