Myelomeningocele repair at pediatric hospitals: association with routine discharge and shorter hospital stay

Abstract

OBJECTIVE Postnatal repair for myelomeningocele (MMC) is a time-sensitive and technically challenging procedure. More experienced hospitals may provide improved outcomes for the complexity of care associated with these patients. No prior study has investigated the impact of MMC treatment at pediatric hospitals. The authors sought to examine the effect of pediatric hospital designation on patients undergoing postnatal MMC repair to identify factors associated with maximizing improved patient outcomes. METHODS The Nationwide Readmissions Database records from 2010 to 2018 were analyzed retrospectively to determine the effect of hospital designation on patient outcomes after postnatal MMC repair. Univariate and multivariate regression analyses of patient and hospital characteristics were conducted to evaluate if MMC repair at a designated pediatric hospital was independently associated with patient outcomes of perinatal infection rates, discharge disposition, and length of stay. RESULTS Of the total of 6353 pediatric patients who underwent postnatal MMC repair between 2010 and 2018, 2224 (35.0%) received care at a pediatric hospital. Those with an extreme level of disease burden as defined by the all patient refined diagnosis-related group severity of illness index were more likely to be treated at a pediatric hospital (p = 0.03). Patients undergoing repair at a pediatric hospital were also associated with a decreased likelihood of perinatal infection (OR 0.54, 95% CI 0.35–0.83, p = 0.005); greater likelihood of routine disposition (OR 4.85, 95% CI 2.34–10.06, p < 0.0001); and shorter length of stay (incidence rate ratio 0.88, 95% CI 0.77–0.995, p = 0.04). CONCLUSIONS Pediatric patients requiring intervention for postnatal repair of MMC may benefit from the multidisciplinary subspeciality care offered at pediatric hospitals. The authors found that postnatal repair of MMC at pediatric hospitals was associated with a greater likelihood of improved patient outcomes.
