RESUMEN
BACKGROUND: The rise of value-based purchasing has led to decreased compensation for hospital-acquired conditions, including surgical site infections (SSI). This study aims to assess the risk factors for SSI in children and teenagers undergoing gastrointestinal surgery across US hospitals. METHODS: The 2018-2020 Nationwide Readmissions Database was queried for patients undergoing gastrointestinal surgery under the age of 18. The primary outcome was SSI during index admission or readmission within a year. Comparison groups were elective, trauma, and emergent surgery based on anatomic location and urgency. Univariable comparison used chi-squared tests for relevant variables. Confounders were addressed through multivariable logistic regression with significant variables from univariable analysis. RESULTS: 113 108 total patients met the study criteria. The SSI rate during admission or readmission was 2.9% (n = 3254). Infections during admission and readmission were 1.4% (n = 1560) and 1.5% (n = 1694), respectively. The most common site was organ space (48.6%, n = 1657). Increased infection risk was associated with trauma (OR 1.80 [1.51-2.16] P < .001), emergency surgery (OR 1.31 [1.17-1.47] P < .001), large bowel surgery (OR 2.78 [2.26-3.43] P < .001), and those with three or more comorbidities (OR 2.03 [1.69-2.45] P < .001). Investor-owned hospitals (OR .65 [.56-.76] P < .001) and highest quartile income (OR .80 [.73-.88] P < .001) were associated with decreased infection risk. CONCLUSIONS: Pediatric patients undergoing gastrointestinal surgery face an elevated risk of SSI, especially in trauma and emergency surgeries, particularly with multiple comorbidities. Meanwhile, a reduced risk is observed in high-income and investor-owned hospital settings. Hospitals and surgeons caring for high risk patients should advocate for risk adjustment in value-based payment systems.
