Insights
A new prediction model accurately identifies infants at birth at high risk for severe neonatal opioid withdrawal syndrome (NOWS). This tool helps clinicians tailor care and avoid unnecessary treatments for infants exposed to opioids.
Area of Science:
- Neonatal care
- Pharmacology
- Clinical prediction models
Background:
- Neonatal opioid withdrawal syndrome (NOWS) management guidelines recommend up to 7 days of observation for infants with chronic opioid exposure.
- However, not all exposed infants develop NOWS, and some with less apparent exposure may experience severe symptoms requiring pharmacotherapy.
- Current screening methods may not optimally identify infants at risk for severe NOWS.
Purpose of the Study:
- To adapt and validate a prediction model for identifying infants at birth who are likely to develop severe NOWS.
- To compare the performance of the prediction model against existing guideline screening criteria.
Main Methods:
- A prognostic study involving 33,991 births was conducted.
- Severe NOWS was defined by the administration of oral morphine.
- A logistic regression model with a least absolute shrinkage selection operator approach was developed using 37 predictors.
- Decision curve analysis was used to compare the model with chronic opioid exposure screening (maternal OUD diagnosis or long-acting opioid prescription).
Main Results:
- 108 infants received oral morphine for NOWS, and 1243 had chronic opioid exposure.
- The prediction model demonstrated high discriminative ability with an area under the receiver operating curve of 0.959.
- Maternal diagnosis of opioid use disorder (OUD) was the strongest predictor (adjusted odds ratio, 47.0).
- Decision curve analysis indicated superior clinical utility of the model across all risk levels compared to guideline criteria.
Conclusions:
- Risk prediction for severe NOWS at birth can enhance clinical decision-making.
- The model aids in tailoring non-pharmacologic interventions and determining the need for extended hospitalization.
- This approach offers a more precise method than solely screening for chronic opioid exposure.
Background:
The American Academy of Pediatrics recommends up to 7 days of observation for neonatal opioid withdrawal syndrome (NOWS) in infants with chronic opioid exposure. However, many of these infants will not develop NOWS, and infants with seemingly less exposure to opioids may develop severe NOWS that requires in-hospital pharmacotherapy. We adapted and validated a prediction model to help clinicians identify infants at birth who will develop severe NOWS.
Methods:
This prognostic study included 33 991 births. Severe NOWS was defined as administration of oral morphine. We applied logistic regression with a least absolute shrinkage selection operator approach to develop a severe NOWS prediction model using 37 predictors. To contrast the model with guideline screening criteria, we conducted a decision curve analysis with chronic opioid exposure defined as the mother receiving a diagnosis for opioid use disorder (OUD) or a prescription for long-acting opioids before delivery.
Results:
A total of 108 infants were treated with oral morphine for NOWS, and 1243 infants had chronic opioid exposure. The model was highly discriminative, with an area under the receiver operating curve of 0.959 (95% CI, 0.940-0.976). The strongest predictor was mothers' diagnoses of OUD (adjusted odds ratio, 47.0; 95% CI, 26.7-82.7). The decision curve analysis shows a higher benefit with the model across all levels of risk, compared with using the guideline criteria.
Conclusion:
Risk prediction for severe NOWS at birth may better support clinicians in tailoring nonpharmacologic measures and deciding whether to extend birth hospitalization than screening for chronic opioid exposure alone.
