1 Significance f Chrnic Kidney Disease in 2015 There is still a requirement within QOF t keep a register f peple with CKD stages 3-5. The ther CKD QOF targets have been retired. This is because CKD care shuld nw be embedded within daily practice; it is nt because CKD is nw felt t be less imprtant, r verdiagnsed. A small, althugh imprtant, minrity f peple with CKD will develp mre advanced renal failure where dialysis r transplantatin may be required. Hwever, fr the verwhelming majrity, CKD is f greater significance fr ther reasns: fr safe prescribing and medicines management (including ver the cunter medicatins such as NSAIDs) as a pwerful and mdifiable risk factr fr cardivascular disease; current NICE Guidance n Lipid Mdificatin (CG181, 2014) is that: CV risk scres (eg QRISK2) are nt used in peple with CKD, and that Atrvastatin 20 mg d is ffered t all peple with CKD as a risk factr fr Acute Kidney Injury (AKI), a majr cause f avidable harm: minr impairment in egfr at any age dramatically increases the risk f AKI ACE inhibitrs, angitensin receptr blckers, and metfrmin shuld - subject t an individual risk assessment - be temprarily stpped during acute intercurrent illnesses (e.g. significant febrile illness, diarrhea and vmiting) t reduce the risk f AKI ( sick day rules ) Revised NICE Guidance n CKD was published in 2014.

Fllw up f peple with knwn CKD 3 All peple with CKD need lng-term mnitring f their kidney functin NICE 2015 recmmend that CKD is classified using a cmbinatin f egfr and ACR as these tw measures are independently assciated with increased risk. The frequency f mnitring f egfr (i.e. number f measures per year) is then guided by the fllwing Table (frm NICE CG182, 2014): The frequency f mnitring f ACR (r PCR) will vary accrding t individual circumstances. In many cases the ACR (PCR) will need t be measured less frequently than the egfr
