Is NSQIP Pediatric review representative of total institutional experience for children undergoing appendectomy?

Background/purpose: NSQIP Pediatric (NSQIP-P) is a robust quality improvement effort. A limitation of the NSQIP process lies in capturing a small proportion of the total case volume. This study examines whether appendectomies captured by NSQIP-P are concordant with all appendectomies, the most commonly captured procedure in 2011.
