Pediatric surgical readmissions: Are they truly preventable?

BACKGROUND/PURPOSE: Reimbursement penalties for excess hospital readmissions have begun for the pediatric population. Therefore, research determining incidence and predictors is critical.

METHODS

A retrospective review of University HealthSystem Consortium database (N=258 hospitals; 2,723,621 patients) for pediatric patients (age 0-17years) hospitalized from 9/2011 to 3/2015 was performed. Outcome measures were 7-, 14-, and 30-day readmission rates. Hospital and patient characteristics were evaluated to identify predictors of readmission.

RESULTS

Readmission rates at 7, 14, and 30days were 2.1%, 3.1%, and 4.4%. For pediatric surgery patients (N=260,042), neither index hospitalization length of stay (LOS) nor presence of a complication predicted higher readmissions. Appendectomy was the most common procedure leading to readmission. Evaluating institutional data (N=5785), patients admitted for spine surgery, neurosurgery, transplant, or surgical oncology had higher readmission rates. Readmission diagnoses were most commonly infectious (37.2%) or for nausea/vomiting/dehydration (51.1%). Patients with chronic medical conditions comprised 55.8% of patients readmitted within 7days. 92.0% of patients requiring multiple rehospitalizations had comorbidities.

CONCLUSIONS

Readmission rates for pediatric patients are significantly lower than adults. Risk factors for adult readmissions do not predict pediatric readmissions. Readmission may be a misnomer for the pediatric surgical population, as most are related to chronic medical conditions and other nonmodifiable risk factors.
