Prevalence of CKD in USA
NHANES: 11.2% of the US population have chronic kidney disease:
– Stage 1 – Stage 2 – Stage 3 – Stage 4 – Stage 5 (normal GFR) (GFR 60-90) (GFR 30-60) (GFR 15-30) (GFR 0-15) 3.3% 3.0% 4.3% 0.2% 0.2%

Prevalence of CKD UK
East Kent: Clinical biochemistry lab survey
– Prevalence of SCr (µmol/l) > 180 (m) or >135 (f) – 5554 per million of population
• • • • Age related: 78.3 pmp <40y, 58913 pmp >80y Only 15.2% known to renal service Only 5.7% referred over the subsequent 12 months 1 year mortality 31.5%
– Incidence of new CKD of this severity: – 2425 per million population John I. AJKD (2005) 43(5): 825-835.

Consequences of Late Referral for Patients With Chronic Kidney Disease
Loss of chance for patients
30-50% of patients present < 3 months prior to dialysis Mortality in late presenters in greatly increased 50% could have been referred earlier Commonest late referrals are diabetics (13%)
Roderick, P et al. QJM (2002) 95: 363 - 370

Consequences of Late Referral for Patients With Chronic Kidney Disease
Financial cost
1391 patients started renal replacement therapy 1989-2000 Late referral - less than 3 months in 30% Preventable cause in 6.8% (= 95 patients) Life time cost £14,250,000

Pre Dialysis
Pre dialysis care > 1 year is associated with
– – – – – – – – Slower progression to dialysis Lower co morbidity at start of dialysis Lower hospitalisation rates Improved survival Improved rehabilitation Greater likelihood of maintaining employment Better response to vaccination Higher % with AVF

Current Situation
Current system is unable to cope with the problem Have to create a new way of managing these patients. Renal NSF & Joint Royal Colleges:
Automatic patient identification by eGFR from labs Primary care based multidisciplinary management Protocol/algorithm based management Defined indications for referral to nephrologist Audited outcome targets e.g. BP & cholesterol

The Optimal Programme
Automatic patient identification Algorithm based referral and management Improve performance against defined clinical targets Reduce comorbidity Reduce resource utilisation Reduce cost per patient

Problems
Lack of GP buy in due to:
– Increased work load – Increased cost – No payment (not in QOF)
GPs don’t routinely test urine Failure to follow guidelines Lack of IT integration

In conclusion
Identified majority of patients with CKD within WL PCT Instituted patient education programme
Changed the referral process
Ensure that patients are referred appropriately and in a timely manner Improves patient outcomes?
Reduction in resource utilisation?
