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.
