Assessment of neuromonitoring use and postoperative readmission rates in pediatric Chiari I malformation with syrinx

Introduction While operative intervention for Chiari malformation type I (CMI) with syringomyelia is well established, there is limited data on outcomes of intraoperative neuromonitoring (IONM).

Zusammenfassung:Introduction While operative intervention for Chiari malformation type I (CMI) with syringomyelia is well established, there is limited data on outcomes of intraoperative neuromonitoring (IONM). This study sought to explore differences in procedural characteristics and their effects on postoperative readmission rates. Methods The Nationwide Readmission Database was queried from 2010 to 2014 for patients ≤ 18 years of age with CMI and syringomyelia who underwent cranial decompression or spinal decompression. Demographics, hospital characteristics, and outcomes were analyzed. Results Over the 5-year period, 2789 patients were identified that underwent operative treatment for CMI with syringomyelia. Mean age was 10 ± 4 years with 55% female. During their index hospitalization 14% of the patients had IONM. Patients receiving IONM had no significant difference in Charleston Comorbidity Index ≥ 1 (16% vs. 15% without, p  = 0.774). IONM was more often used in those with private insurance (63% vs. 58% without, p  = 0.0004) and less likely in those with Medicaid (29% vs. 37% without, p  = 0.004). Patients receiving IONM were more likely to have a postoperative complication (23% vs 17%, p  = 0.004) and were more likely to have hospital lengths of stay > 7 days (9% vs. 5% without, p  = 0.005). Readmission rates for CMI were 9% within 30 days and 15% within the year. The majority (89%) of readmissions were unplanned. 25% of readmissions were for infection and 27% of readmissions underwent a CMI reoperation. The 30-day readmission rate was higher for those with IONM (12% vs. 8% without, p  = 0.010). Median cost for hospitalization was significantly higher for patients with IONM ($26,663 ($16,933–34,397)) vs. those without ($14,577 ($11,538–18,392)), p
