Background:
The first-line treatment for intussusception is radiologic reduction with either air-contrast enema (AE) or liquid-contrast enema (LE). The purpose of this study was to explore relationships between self-reported institutional AE or LE intussusception reduction preferences and rates of operative intervention and bowel resection.
Methods:
Pediatric Health Information System (PHIS) hospitals were contacted to assess institutional enema practices for intussusception. A retrospective study using 2009-2018 PHIS data was conducted for patients aged 0-5 y to evaluate outcomes. Chi-squared tests were used to test for differences in the distribution of surgical patients by hospital management approach.
Results:
Of the 45 hospitals, 20 (44%) exclusively used AE, 4 (9%) exclusively used LE, and 21 (46%) used a mixed practice. Of 24,688 patients identified from PHIS, 13,231 (54%) were at exclusive AE/LE hospitals and 11,457 (46%) were at mixed practice hospitals. Patients at AE/LE hospitals underwent operative procedures at lower rates than at mixed practice hospitals (14.8% versus 16.5%, P< 0.001) and were more likely to undergo bowel resection (31.1% versus 27.1%, P= 0.02).
Conclusions:
Practice variation exists in hospital-level approaches to radiologic reduction of intussusception and mixed practices may impact outcomes.
