Condition
Chronic kidney disease
Intervention
The following prompt will be added to laboratory reports for patients who meet the inclusion criteria and are seen by a physician practice randomized to receive the prompt:
This patient has reduced kidney function and is at risk for cardiovascular events and progression to kidney failure. The National Kidney Foundation recommends:
1. Measure random urine albumin to creatinine (Alb:Cr) ratio
2. Institute an angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) in patients with diabetes, or those with an Alb:Cr >35 mg/mmol
3. Referral to a nephrologist if GFR <30 ml/min/1.73 m^2
4. Assess and treat modifiable risk factors for cardiovascular (CV) and renal disease:
a. Target blood pressure (BP) less than 130/80 mmHg
b. Target low-density lipoprotein cholesterol(LDL-C) <2.5 mmol/l
c. If diabetic, target hemoglobin A1C (HbA1C) <7.0%
The above recommendations are general in nature and may not apply to all patients. Further information is available at http://www.akdn.info
The control group will receive usual care.
Intervention type
Other
Primary outcome measure
Use of ACEi or ARB in patients >65 years of age with CKD who have a clear indication for ACEi or ARB use as defined by the presence of diabetes or significant albuminuria.
Secondary outcome measures
1. Use of an ACEi or ARB in patients >65 years of age with CKD
2. Subsequent measurement of lipids, hemoglobin A1C (in patients with diabetes, if not done in previous six months), urine protein or urine albumin, and subsequent frequency of measurement of serum creatinine
3. Referral to a specialist
4. Addition of cholesterol-lowering drugs in patients >65 years of age
5. Addition of new blood pressure medication(s) in patients >65 years of age
6. Health care costs

Eligibility
Participant inclusion criteria
All patients >18 years of age who are registered with one of the participating general practices and have a GFR measured at <60 ml/min during the one-year study period will be included. All participating general practices will be geographically separated (not located in the same office building), and staffed by >1 full time practitioners who do not see outpatients in another general practice unit (to reduce the risk of contamination).
