About Chronic Kidney Disease
The kidneys filter blood, regulate blood pressure, manage fluid balance, and produce hormones that control red blood cell production. Chronic kidney disease (CKD) occurs when the kidneys are progressively damaged over months or years, gradually losing their filtering function. The primary marker is eGFR — estimated glomerular filtration rate — a measure of how much blood the kidneys filter per minute.
CKD is staged from 1 (mildest — eGFR > 90 but with evidence of kidney damage) to 5 (end-stage renal disease / ESRD — eGFR < 15, requiring dialysis or transplant).
South Africa faces a severe CKD burden, driven by three conditions that are each at epidemic proportions: HIV-associated nephropathy (kidney damage from HIV infection), hypertensive nephropathy, and diabetic nephropathy. Hypertension and diabetes — the two leading drivers of CKD — affect approximately 40–50% and 12–15% of South African adults respectively.
CKD Stages and Progression
| Stage | eGFR (mL/min/1.73m²) | Description |
|---|---|---|
| Stage 1 | ≥ 90 | Normal filtration but kidney damage markers present |
| Stage 2 | 60–89 | Mildly decreased filtration |
| Stage 3a / 3b | 30–59 | Moderately decreased filtration. Symptoms begin. |
| Stage 4 | 15–29 | Severely decreased. Pre-dialysis preparation. |
| Stage 5 (ESRD) | < 15 | Kidney failure. Dialysis or transplant required. |
Treatment Options
Conservative Management (Stages 1–4)
The goal is to slow progression and manage complications: - Blood pressure control: target < 130/80 mmHg. ACE inhibitors and ARBs are first choice — they protect kidney function beyond blood pressure reduction. - Blood glucose control in diabetic CKD: tight glucose management slows nephropathy. - SGLT-2 inhibitors (dapagliflozin): proven renoprotective effect in CKD independent of diabetes (DAPA-CKD trial). Not in standard CDL formulary but increasingly motivated by nephrologists. - Low-protein diet (Stage 3–4): reduces metabolic load on kidneys. - Anaemia management: CKD causes anaemia as the kidneys produce less erythropoietin. Erythropoiesis-stimulating agents (ESA — darbepoetin, epoetin) replace this. - Phosphate management: phosphate binders prevent vascular calcification.
Haemodialysis (Stage 5 / ESRD)
Three sessions per week, 4 hours each, at a dialysis unit. Blood is pumped through a dialysis machine (artificial kidney), filtered, and returned. Most South African private sector dialysis is in-centre at dedicated units.
Private cost: R32,500–R52,000/month (Advanced Renal Care, 2026).
Peritoneal Dialysis (PD) (Stage 5 / ESRD)
Home-based. A catheter is placed in the abdomen; dialysis fluid is exchanged manually (CAPD — 4×/day) or via overnight machine (APD). More lifestyle-friendly than in-centre HD; different risk profile (peritonitis risk).
Estimated cost: R280,000–R420,000/year (lower than in-centre HD).
Renal Transplant (Stage 5 / ESRD)
Definitive treatment. A deceased or living donor kidney is surgically implanted. Results in dramatically better long-term outcomes than dialysis. Requires lifelong immunosuppression. Transplant procedure: ~R300,000 (estimate). Annual immunosuppression: ~R36,000.
Annual Cost Estimates (Private Sector)
| Stage | Profile | Estimated Annual Cost |
|---|---|---|
| Stages 1–3 (conservative) | ACE inhibitor, annual nephrology review, bloods | ~R9,200 |
| Stage 4 (pre-dialysis) | ESA + phosphate binders + frequent monitoring | ~R21,600 |
| Stage 5 (in-centre HD) | Dialysis 3×/week, all year | R405,600–R639,600 |
The PMB and CDL Position
CKD is a CDL condition. Schemes must fund:
- RAAS blockade (ACE inhibitor / ARB) for hypertensive/diabetic CKD
- ESA therapy for CKD anaemia (under managed care programmes)
- Dialysis (haemodialysis or peritoneal dialysis) at ESRD — at the designated service provider (DSP) rate
- Renal transplant procedure + post-transplant immunosuppression (lifelong)
- Nephrologist consultations
Critical condition: CDL dialysis funding requires using the scheme's designated service provider (DSP) dialysis network. Non-DSP dialysis generates a co-payment. The network question is the single most important coverage detail for any CKD Stage 5 patient.
Major networks: - Advanced Renal Care (ARC) — largest private dialysis network in SA - National Renal Care (NRC) — Bestmed's designated dialysis DSP
Gap Cover Relevance
| Scenario | Gap Cover Relevance |
|---|---|
| Conservative CKD management (Stages 1–4) | LOW — primarily GP and nephrology visits |
| Dialysis (in-network DSP) | LOW for dialysis itself; MEDIUM for admission complications |
| Dialysis access infection (AV fistula / catheter) | HIGH — vascular surgeon + infectious disease shortfall |
| Hyperkalaemia / fluid overload emergency | HIGH — ICU + specialist shortfall |
| Renal transplant (surgery) | MEDIUM-HIGH — transplant surgeon and anaesthesiologist shortfall |
The Talk to Eldon Angle
Dialysis costs R390,000–R624,000/year in private. Your scheme must cover this as PMB for ESRD. The coverage works only if you use the designated dialysis network. The scheme's DSP network is the most important CKD coverage detail. This is a scheme-level decision that transcends plan selection. Patients with CKD Stage 3–4 should plan their scheme selection with ESRD in mind — long before they reach Stage 5.
Prevention: controlling blood pressure (< 130/80) and glucose costs R200–400/month. Dialysis costs R32,500–52,000/month. The financial case for early CKD management is overwhelming.
