Conformance to several performance measures (A) decreased with more severe renal dysfunction, including assessment of left ventricular function, ACEI or ARB therapy, and β-blocker therapy. However, provision of discharge instructions and smoking cessation referral were only significantly lower among those with kidney failure. Conformance to quality measures (B) decreased with more severe renal dysfunction for last blood pressure < 140/90 and anticoagulation with atrial fibrillation, while they were lower only among those with kidney failure for specific evidence-based β-blocker therapy. Error bars represent 95% confidence intervals and P-values are for trends across kidney function groups for each performance and quality measure.
