Efforts to Reduce Infections in Delayed Sternal Closure Patients: A Survey of Pediatric Practice.

Abstract

Pediatric patients with sternum left open after cardiac surgery experience a higher risk for sternal wound infection (SWI). These infections are costly for programs, payers, and patients and their families. Despite efforts by individual programs to reduce infections in patients undergoing delayed sternal closure (DSC), there are no established guidelines that address preventive procedures. The purpose of this study was to determine the practice of pediatric cardiac surgery programs to prevent infection in their DSC patients and if preventive measures were associated with less infections. A 33 question survey on institutional practices was sent to chief surgeons at pediatric cardiac surgery programs in the United States. Twenty-eight (35%) surgical programs responded. The mean number of pediatric cardiac bypass operations performed by programs in 2016 was 227 (range: 69-872). Data represented 6,484 patients <18 years of age who underwent cardiac surgery with 807 (12%) of those undergoing DSC. One hundred fifty-eight (2.4%) of all patients and 51 (6.3%) of the DSC patients developed a SWI. Patients with DSC who received preoperative baths were less likely to become infected (5.9% vs 15.8%; P = .015). Patients in programs with feeding protocols had fewer infections (5.7% vs 14.8%; P = .008). The results of this survey of children's cardiac surgery programs describe their practices to reduce infection rates in DSC patients. A multicenter project on wound care and closure techniques that might impact this costly complication is needed.
