Objective: To compare time to first dose of oral morphine used in the treatment of neonatal abstinence syndrome (NAS) in a neonatal intensive care unit (NICU) versus a special care nursery (SCN) setting.
Methods: A retrospective chart review was completed of patient data from two community hospitals in a single health network. Infants born at either facility between January 2013 and August 2015 were eligible for inclusion in the study if treated for NAS with a course of oral morphine. The primary outcome was time from birth to first dose of oral morphine. Secondary outcomes included details about the morphine treatment course, length of stay, and complications from NAS.
Results: A total of 54 patients (19 NICU patients and 35 SCN patients) fulfilled inclusion criteria for the study. The primary outcome of median time from birth to first dose of oral morphine did not differ between the two groups (42.5 hrs [NICU] vs 43 hrs [SCN], p=0.53). No significant differences were found between the morphine regimens used in the two units. The median length of hospital stay (27 days [NICU] vs 26 days [SCN], p=0.66) and median length of NICU/SCN stay (26 days [NICU] vs 23 days [SCN], p=0.75) were not statistically significantly different. Time between transfer to the NICU or SCN and administration of the first dose of oral morphine was significantly shorter in the SCN setting (28 hrs [NICU] vs 4 hrs [SCN], p=0.009).
Conclusions: This study found that infants treated for NAS had similar treatment in an NICU and an SCN. No difference was observed in time from birth to initiation of medication therapy. In addition, no differences were seen in all but one marker for quality of care including length of stay and cumulative morphine dose. Infants treated for NAS, whether in an NICU or SCN setting, can receive similar treatment and comparable outcomes.
