Abstract

Background: Central Venous Catheter (CVC) is indispensable to unplanned and urgent start haemodialysis in chronic kidney disease (CKD). While cuffed CVC is preferred to non-cuffed CVC for urgent start haemodialysis, patient’s clinical condition might warrant immediate insertion of non-cuffed CVC. In the resource poor setting, non-cuffed CVCs might have to be retained longer than guideline recommended limit of 2 weeks. In this multi-centre retrospective observational study, the real-world survival of non-cuffed CVC was assessed among CKD patients who initiated dialysis urgently. Methods: CVC survival was assessed by Kaplan-Meier survival estimate. Predictors of premature CVC loss were assessed using multi-level multi-variate Cox frailty model wherein, each centre was provided with a random intercept to account for within-centre correlation of practice patterns. Results: Among 433 non-cuffed CVCs, there were 393 removals out of which 80% were elective and 20% were premature. The median CVC survival was 37 days (95% CI: 35–41). The rate of premature CVC removal was 4.5/1000 CVC-days (95% CI: 3.6–5.6). Mechanical complications followed by central line associated blood stream infection (CLABSI) were the most common reasons for premature removal. Rate of CLABSI was 1.7/1000 CVC-days (95% CI: 1.2–2.5). Diabetic CKD significantly increased the hazard of premature CVC removal (HR 1.91, 95% CI: 1.01–3.63, p = 0.04) while right internal-jugular location decreased the hazard (HR 0.22, 95% CI: 0.13–0.38, p < 0.001). Conclusion: Prolonged retention of non-cuffed CVC (median 37 days) is common in resource-poor setting. It is worrisome and calls for pre-emptive access creation.
