Abstract

BackgroundHealthcare delivery is reliant on a functional central venous access device (CVAD), but the knowledge surrounding the burden of pediatric CVAD-associated harm is limited.MethodsA prospective cohort study at a tertiary-referral pediatric hospital in Australia. Children <18 years undergoing insertion of a CVAD were screened from the operating theatre and intensive care unit records, then assessed bi-weekly for up to 3 months. Outcomes were CVAD failure and complications, and associated healthcare costs (cost of complications).Results163 patients with 200 CVADs were recruited and followed for 6993 catheter days, with peripherally inserted central catheters most common (n = 119; 60%). CVAD failure occurred in 20% of devices (n = 30; 95% CI: 15–26), at an incidence rate (IR) of 5.72 per 1000 catheter days (95% CI: 4.09–7.78). CVAD complications were evident in 43% of all CVADs (n = 86; 95% CI: 36–50), at a rate of 12.29 per 1000 catheter days (95% CI: 9.84–15.16). CVAD failure costs were A$826 per episode, and A$165,372 per 1000 CVADs. Comparisons between current and recommended practice revealed inconsistent use of ultrasound guidance for insertion, sub-optimal tip-positioning, and appropriate device selection.ConclusionsCVAD complications and failures represent substantial burdens to children and healthcare. Future efforts need to focus on the inconsistent use of best practices.ImpactCurrent surveillance of central venous access device (CVAD) performance is likely under-estimating actual burden on pediatric patients and the healthcare system.CVAD failure due to complication was evident in 20% of CVADs. Costs associated with CVAD complications average at $2327 (AUD, 2020) per episode.Further investment in key diverse practice areas, including new CVAD types, CVAD pathology-based occlusion and dislodgment strategies, the appropriate use of device types, and tip-positioning technologies, will likely lead to extensive benefit.
