Little is known about the factors influencing surgical practice variation in newborns with gastroschisis. The purpose of this study was to correlate prognostic variables with the intended and actual abdominal closure technique and assess related outcomes.
GS cases were abstracted from a national database. Variables evaluated included GA, BW, bowel injury severity (GPS), neonatal illness severity (SNAP-II), inborn status, center volume and training status, and admission time. Evaluated outcomes by closure method included duration of TPN, LOS, and complications. Descriptive, univariate and multivariable regression analyses were conducted.
The cohort consisted of 679 patients. A total of 372 (55%) underwent attempted PR, of which 300 (81%) were successful, while 307 (45%) had a silo placed intentionally. Patients undergoing attempted PR were more likely to be inborn, have daytime admissions, and higher SNAP-II scores. Successful PR was predicted by low risk GPS and high volume center. With the exception of higher rates of SSI in the planned silo group, outcomes in the successful PR and planned silo groups were comparable.
Practice variation related to type of closure is predicted by situational and institutional factors (outborn, nighttime admission, and center volume), while outcome variation is attributable to patient factors rather than practice variation.
