The pediatric trauma center and the inclusive trauma system: Impact on splenectomy rates.

BACKGROUND

Before 2006, the Delaware Trauma System (DTS) did not include a designated pediatric trauma center (PTC). In 2006, the Delaware Trauma System designated and the American College of Surgeons Committee on Trauma verification/consultation program verified Nemours AI DuPont Hospital for Children, a freestanding children's hospital, as a PTC. We evaluated the impact of the addition of the PTC to the state trauma system on pediatric traumatic splenectomy rates.

METHODS

The study cohort comprised DTS trauma registry recorded children younger than 16 years with spleen injury (ICD-9 codes 865.0-865.9) from January 1998 through December 2012. This cohort was categorized into pre-PTC (1998-2005) and post-PTC (2006-2012) groups. Penetrating injuries were excluded. Comparisons between groups included age, gender, length of stay, organ-specific injury grade, Injury Severity Score, incidence of polytrauma, splenectomy rate, and admitting hospital. Management, operative versus nonoperative, of low grade (Organ Injury Scale [OIS] score, 1-3) and high grade (OIS score, 4-5) were also compared. Pearson's χ analysis was performed for categorical variables. Continuous variables were reported as mean (standard deviation) and compared by Student's t test for independent normally distributed samples. Mann-Whitney U-test was used for non-normally distributed variables. A value of p < 0.05 was considered significant.

RESULTS

Of the 231 pediatric spleen injuries, 118 occurred pre-PTC and 113 occurred post-PTC. There were no significant differences in age, gender, length of stay, Injury Severity Score, OIS grade, or incidence of polytrauma. Splenectomy rates decreased from 11% (13 of 118) pre-PTC to 2.7% (3 of 113) post-PTC (p = 0.012).

CONCLUSION

The addition of an American College of Surgeons-verified PTC within an inclusive trauma system that was previously without one was associated with a significant reduction in the rate of blunt trauma-related splenectomy. Integration of a verified PTC is an influential factor in achieving spleen preservation rates equivalent to published American Pediatric Surgery Association benchmarks within a trauma system.
