1 The extent of albuminuria in individuals with diabetes within Heart of Birmingham PCT Mark Jesky Research Registrar

2 Background Most management of diabetes (and microalbuminuria) takes place in primary care Factors associated with development and progression of nephropathy well established – Good glycaemic control – Blood pressure management – ACEi/ ARB as antihypertensive agents of choice CKD frequently under-recognised Nephrology input later in course of disease

3 Background HoB PCT – Young, ethnically diverse population – has the highest take up rate of renal replacement therapy within UK – Enhanced, electronic recording of individuals ≥40 years or identified as having a vascular disease Gain insight into practice within primary care setting

4 NICE CKD Guidelines: Diabetes

5 Audit Questions What is the extent of albuminuria within primary care diabetic population? Are NICE CKD guidelines being followed? – checking eGFR and ACR at least annually – if ACR elevated, are ACEi/ARBs being prescribed? Are any factors (age, gender, ethnicity) associated with not having ACR performed?

6 Diabetes and Measurement of Renal function June 2011 extract 21,529 classified as diabetic – HoB population ≈ 300,000 – 7.2% Of those 21,529, within last 12 months – 69.0% (14,854) had an eGFR recorded – 69.0% (14,857) had an ACR recorded 62.5% in National diabetes audit 2010 ~50% National diabetes audit 2008 – 51.2% (11,033) have both eGFR and ACR

9 Adherence to NICE guidelines (Both ACR and eGFR reported) eGFR ≥ 60eGFR 30 -59eGFR <30 No Albuminuria ACR ≤ 2.5 (M), ACR ≤ 3.5 (F) 6335 (57.4%) 1439 (13.3%) 63 (0.57%) Albuminuria ACR > 2.5 (M), ACR > 3.5 (F) 1963 (17.8%) 1017 (9.2%) 216 (2.0%) 42.6% have either albuminuria or moderate CKD c.f. 45% in National Diabetes Audit

10 Adherence to NICE guidelines ACEi/ ARB usage eGFR ≥ 60eGFR 30 -59eGFR <30 No Albuminuria ACR ≤ 2.5 (M), ACR ≤ 3.5 (F) 6335 (57.4%) 1439 (13.3%) 63 (0.57%) Albuminuria ACR > 2.5 (M), ACR > 3.5 (F) 1963 (17.8%) 1017 (9.2%) 216 (2.0%) Of these 2980, 68.2% (2032) on ACEi/ARB, 31.8% (948) not

14 Audit Questions What is the extent of albuminuria within primary care diabetic population? Are NICE CKD guidelines being followed? – checking eGFR and ACR at least annually – if ACR elevated, are ACEi/ARBs being prescribed? Do any factors (age, gender, ethnicity) predispose to not having tests done?

15 Summary ACR assessed in under 70% diabetic population Just over half had ACR and eGFR recorded in last 12 months ACEi/ ARB usage not as extensive as should be People with ACR not checked tend to be – Younger – Pakistani, White, ethnicity not stated – Less likely to have eGFR <60 – Less likely to have other parameters checked Implications for risk stratification More can be done to try to reduce rate of progression in this high risk population
