Standard Fixed-Schedule Methadone Taper Versus Symptom-Triggered Methadone Approach for Treatment of Neonatal Opioid Withdrawal Syndrome.

OBJECTIVES

We compared hospitalization outcomes in infants with neonatal opioid withdrawal syndrome (NOWS) treated with a novel symptom-triggered methadone approach (STMA) versus a fixed-schedule methadone taper (FSMT).

METHODS

This was a single-center quality-improvement study of infants pharmacologically treated for NOWS. Outcomes were compared over time by using statistical process control charts and between the baseline FSMT (July 2016-November 2017) and intervention STMA (December 2017-May 2018) groups, including median hospital length of stay (LOS), methadone treatment days, total milligrams of methadone, and need for adjunctive agents.

RESULTS

There were 48 infants in the FSMT group and 28 in the STMA group. Infants treated with STMA had a median LOS of 10.5 days (interquartile range [IQR] 10.5) versus 17.0 days (IQR 3.9; P = .003) in the FSMT group, with a 9.2-day difference in methadone treatment days (2.5 [IQR 9.0] vs 11.7 [IQR 4.0]; P = .0001), meeting criteria for statistical process control special cause variation. The average number of symptom-triggered doses was 2.1 (SD 1.0). Six infants in the STMA group were converted to FSMT after failing a trial of STMA. Infants successfully treated with the STMA (N = 22) had a median LOS of 10.0 days (IQR 4.0) compared with 17.0 (IQR 3.9) in the baseline FSMT group (P < .0001).

CONCLUSIONS

STMA was associated with a significant reduction in median LOS and amount of methadone treatment. A symptom-triggered approach to NOWS may reduce LOS and medication exposure.
