Dialysis catheters cause 80-134 extra deaths per 1,000 patient-years

Patients who dialyze through a central venous catheter rather than an arteriovenous fistula (AVF) experience 80 to 134 additional deaths per 1,000 patient-years. Catheter-related bloodstream infections occur at a rate of 1.03 per 1,000 patient-days for tunneled catheters (vs. 0.18 for fistulas -- a 5x difference), and temporary catheters are 15x worse at 3.18 per 1,000 patient-days. Yet approximately 80% of U.S. patients start hemodialysis with a catheter rather than a mature fistula. This matters because each catheter infection means hospitalization, IV antibiotics, potential catheter removal and replacement surgery, sepsis risk, and death. Patients with catheters live in constant fear of infection, showering with plastic wrap over their chest, avoiding swimming, and watching for fever. The structural reason this persists is that fistulas take 2-3 months to mature after surgical creation, so they must be placed well before dialysis starts. But because only 41.5% of high-risk CKD patients even see a nephrologist within a year, and many patients 'crash' into dialysis without advance planning, there is no time to create a fistula. Late referral from primary care to nephrology is the upstream cause of downstream catheter deaths.
