Safety of same-day discharge following vagus nerve stimulator insertion in children: a National Surgical Quality Improvement Program study

OBJECTIVE: Vagus nerve stimulator (VNS) insertion has become a common treatment for drug-resistant epilepsy in children. The growing number of children undergoing VNS insertion provides a strong incentive for studies aimed at optimizing postoperative care protocols. The objective of this retrospective study was to characterize the readmission and reoperation rates associated with VNS insertion in children. METHODS: The National Surgical Quality Improvement Program-Pediatric (NSQIP-P) database was queried from 2012 to 2022 to find patients who underwent VNS insertion (CPT code 64568). The primary outcome measured was unplanned readmission within 7 days of VNS insertion. Propensity score matching on the criteria of baseline demographics was applied. Multivariable logistic regression analysis was conducted to determine if age, race, or anesthesia time affected same-day discharge as well as unplanned readmission and reoperation rates. RESULTS: A total of 4267 patients who underwent VNS insertion were identified in the NSQIP-P database from 2012 to 2022. After excluding patients with missing data and readmissions > 7 postoperative days, 3070 patients were included in the final analysis. Of those patients, 63 (2.1%) experienced an unplanned readmission within 7 days of their procedure. Propensity score matching differentiating between those with a total hospital length of stay of 0 days (same-day discharge) and > 0 days (inpatient admission) on the criteria of age (p = 0.63), sex (p = 0.77), race (p = 0.99), Hispanic ethnicity (p = 0.84), and American Society of Anesthesiologists classification (p = 0.18) showed no statistically significant difference in baseline characteristics between the two cohorts. No significant difference in unplanned readmissions was found between patients with same-day discharge versus those with inpatient admission (OR 1.19, 95% CI 0.72-1.99; p = 0.5). CONCLUSIONS: Same-day discharge of pediatric patients undergoing VNS insertion was not associated with higher readmission rates compared to patients who stayed in the hospital for more than 1 day.
