“The 2019 KDOQI guidelines changed the conversation from ‘fistula first’ to ‘patient first’. That shift matters enormously for how we counsel patients with CKD.”

🦥 Why These Guidelines Matter
The KDOQI (Kidney Disease Outcomes Quality Initiative) Vascular Access Guidelines are the gold standard reference for dialysis access worldwide. The 2019 update — the first major revision in 12 years — introduced important conceptual and practical shifts that affect how vascular surgeons, nephrologists, and dialysis units plan and manage access. This guide translates the key changes into plain English.
🔄 The Biggest Shift: From ‘Fistula First’ to ‘PLAN’
The previous guidelines promoted a simple “Fistula First” mantra — create an AV fistula for every dialysis patient, always. The 2019 guidelines replace this with the PLAN concept:
- P — Patient Life-plan: What are the patient’s goals, prognosis, and expectations from renal replacement therapy?
- L — Life expectancy: Patients with very short life expectancy may not benefit from the maturation wait of a fistula
- A — Access needs: What access does this specific patient anatomy and clinical situation support?
- N — Network of care: Is the centre equipped to support fistula maturation, intervention, and surveillance?
In short: a fistula is still the preferred access for most patients — but the decision must now be individualised, not assumed.
📌 Key Changes from the 2006 to 2019 Guidelines
1. Catheters Are Explicitly Acknowledged as Sometimes Appropriate
The 2019 guidelines explicitly state that a tunnelled catheter may be the most appropriate long-term access for certain patients — particularly the elderly, those with terminal illness, those awaiting transplant imminently, or those with no suitable vessels. This acknowledges clinical reality and removes the dogma that a catheter is always a failure.
2. Early Referral Is Reinforced
Referral to a vascular surgeon should occur when eGFR reaches 15–20 ml/min/1.73m² — not when dialysis has already started. This allows time for vein preservation, pre-operative planning, and fistula maturation before the catheter is ever needed.
3. Vein Mapping Is Strongly Recommended
Pre-operative duplex ultrasound vein mapping is now a standard recommendation before all fistula creation. Centres that routinely map veins have better maturation rates, fewer primary failures, and fewer revisions.
4. Surveillance and Monitoring Are Defined More Clearly
The 2019 guidelines draw a clear distinction between monitoring (clinical assessment at each session — look, feel, listen) and surveillance (instrumental testing using flow measurements and dynamic pressures). Both are recommended and complementary. Neither alone is sufficient.
5. Maturation Assessment at 4–6 Weeks
The 2019 update recommends formal clinical and duplex assessment of fistula maturation at 4–6 weeks post-creation, not 3 months. Early assessment means early intervention for failing maturation — improving overall fistula salvage rates.
🙋🏻♂️ Frequently Asked Questions
Does KDOQI still recommend fistulas over grafts?
Yes, in patients with suitable anatomy and adequate life expectancy. The key shift is that the decision is now framed as “which access is best for this patient” rather than “create a fistula for all patients.” Grafts are explicitly recognised as a better choice than a catheter when fistula creation is not feasible.
What does the PLAN concept mean for elderly patients?
For an 85-year-old with multiple comorbidities who is unlikely to survive the 6–12 weeks needed for fistula maturation before needing dialysis, a tunnelled catheter is now an explicitly acceptable primary access. Subjecting such a patient to fistula surgery that will never mature is not good medicine — and the 2019 guidelines formally acknowledge this.
Where can I read the full KDOQI 2019 guidelines?
The full guidelines are freely available via the American Journal of Kidney Diseases (AJKD) and the National Kidney Foundation website. They are lengthy (300+ pages) but the executive summary is very readable and covers the key recommendations concisely.
🔑 Key Insights
The 2019 KDOQI guidelines do not abandon the fistula — they contextualise it. The right access, planned early, for the right patient, supported by proper surveillance: that is the standard of care.
