Renal disease codes [This list needs populating from the meeting 29/5/13] Inclusions (agreed 29/5/13): DM with microalbuminuria Systemic disease coded only where nephritis/renal involvement is specified. Alports, Cystic disease, Fabry’s CKD stage 1/2 codes Proteinuria Codes This is both a code for proteinuria (as a renal condition) and codes for dipstick positive proteinuria (>1+).

19. The percentage of people with CKD who are assessed for kidney disease progression and related problems according to their disease stage [*, QS6] Based on eGFR/urine laboratory results/timing. For CKD 3B percentage that had Hb measured. The percentage of people with defined indicators for referral who were referred to secondary care [*, QS2] within 3 months of abnormal results eGFR/urine results and timing, high blood pressure despite 4 antihypertensive drug classes, read-codes for referral and/or renal ultrasound, pop-up box for GPs to fill in if phone or e-mail advice from specialistswas given The percentage of people with CKD who are assessed for cardiovascular risk [*, QS4] Management The percentage of people with CKD who have a current agreed care plan [QS3] by 1 year read-code on whether patients were informed about their diagnosis (once available), see 4.3. The percentage of people with CKD who have blood pressures in the NICE recommended target range by 1 year [*, QS5] Includes proportion of patients on renin-angiotensin blocking drugs according to proteinuria status The percentage of people with CKD who are treated with statins according to their cardiovascular risk by 1 year [*] Primary and secondary prevention as per updated NICE lipid guideline (once available) The percentage of people with CKD who had their medication reviewed whilst acutely unwell The percentage of people with CKD who were vaccinated for influenza (NICE TA158) For CKD stages 4 &5 this would also apply to pneumococcal virus and Hepatitis B if seronegative (KDIGO CKD guideline 2013). The percentage of people with CKD 4&5 who have phosphate and haemoglobin measurements on GP laboratory systems. [*] #
