Outcomes of Pediatric Central Venous Access Device Placement With Concomitant Surgical Procedures

Abstract

BackgroundChildren frequently undergo placement of a tunneled central venous catheter or port (CVAD) concomitantly with other surgical procedures (CVAD-CP), but the risk factors for early CVAD complications with this practice are unclear. MethodsChildren undergoing CVAD-CP were identified from the National Surgical Quality Improvement Program-Pediatric 2012-2016 database. Predictor variables included demographics, CP characteristics, malignancy, and CVAD type. Outcome variables were CVAD-associated bloodstream infection (CLABSI) or new deep venous thrombosis (nDVT) within 30 d. Patients with and without CLABSI or nDVT were compared, and the temporal relationship of nDVT and CLABSI was investigated. Multivariable logistic regression modeling was used to assess independent risk factors for CLABSI. ResultsOf 2036 patients included, median age was 1.5 y, 35% had malignancy, and 40% had a clean concomitant procedure. Overall, 1.3% developed CLABSI and 0.7% developed nDVT. Multivariable regression modeling revealed higher risk of CLABSI with clean CPs (odds ratio [OR] 2.4, 95% confidence interval [CI] 1.06-5.34, P = 0.035), tunneled catheters (OR 3.2, 95% CI 1.18-8.56, P = 0.022), and longer anesthesia duration (OR 1.02 per 10 min, 95% CI 1.00-1.04, P = 0.042). nDVT was strongly associated with CLABSI (21% CLABSI among those with DVT, 0.5% among those without, P ≤ 0.0001). In all cases of nDVT with CLABSI, the diagnosis of DVT preceded diagnosis of CLABSI, by a median of 7 d. ConclusionsThe type of CVAD and characteristics of the concomitant procedure influence early CLABSI after CVAD-CP. The unexpected finding of higher CLABSI rates among clean concomitant procedures suggests that perioperative prophylactic antibiotics should not be withheld in this setting, but requires prospective validation. nDVT is frequently diagnosed prior to CLABSI, suggesting a possible role for antibiotics in the treatment of postoperative DVT after CVAD placement.
