Measure and record at diagnosis and at every visit therea ter. See BC guideline:Hypertension Detection, Diagnosis and Management at www.BCGuidelines.ca
Obtain regular measurements o serum creatinine or eGFR (at least q 6 months)and a ter any change in medications, medical intervention, or clinical status.
ACR (microalbumin) every 6-12 months or as clinically indicated.
Measure a ter change in medications, medical intervention, or clinical statuswith particular attention to K +.
Check serum creatinine and K + prior to starting ACEIs and ARBs, within 2weeks o starting, and within 2 weeks a ter dose increase.
Serum creatinine rise >20% or eGFR decrease >15% a ter dose increaseshould be ollowed by urther measurements within 2 weeks.
Calculate & record CVD risk. Manage in accordance with relevant guidelines. Check asting lipids yearly once target values are achieved & more requently
in patients on lipid lowering medication. Measure A1C q 3 months or as clinically indicated. SeeDiabetes Care guideline
at www.BCGuidelines.ca Long-acting sul onylureas may be associated with hypoglycemia with unstable
eGFR, especially those below 45. I recurrent hypoglycemia, or unstable eGFRconsider using short-acting sul onylureas or non-sul onylureas.
In those with unstable eGFR or acute changes in clinical condition, met orminshould be held.
Record weight & BMI on each visit or comparison.
Encourage patient to stop smoking, enquire at every visit, support when receptive.Measure at least yearly (more requently with advanced CKD): CBC. Mineral metabolism (calcium, phosphorus, iPTH).
Nutrition pro le (albumin).
Immunize annually.Immunize every 10 years.
Immunization at a higher level o eGFR more likely to result in seroconversioni patient is being considered or hemodialysis. Screening and vaccination inconsultation with nephrology team. Reduce risk o acute or chronic deterioration o kidney unction.
Adjust renally excreted drugs according to kidney unction.
Depression and grie reaction may occur with chronic disease. Identi y and address psychosocial problems that a ect the illness.

CKD is a se ious o ulation health o le with a signi cant i act on individuals a ilies societyand health se vices.
