Background: The aim of this study was to assess the impact of follow-up in renal protection clinics on the prescription of and adherence to cardioprotective drugs in patients with chronic kidney disease (CKD). Methods: We studied stage 4 and 5 CKD patients who initiated follow-up in three renal protection clinics. The prescription pattern of antihypertensive agents (AHA) and lipid-lowering agents (LLAs) was measured as the percentage of patients who are prescribed the agents of interest at a given time. Adherence to drug therapy was defined as the percentage of days, during a pre-defined observation period, in which patients have an on-hand supply of their prescribed medications. Results: A total of 259 CKD patients were enrolled and followed for up to 1 year after referral to renal protection clinics. There was a significant increase in the prescription of angiotensin-converting enzyme inhibitors (34-39%), angiotensin II receptor blockers (11-14%), beta-blockers (40-51%), calcium channel blockers (62-74%), diuretics (66-78%) and LLAs (39-47%) during follow-up in the renal protection clinic compared with baseline (P-values<0.01 for all comparisons). The proportions of patients with good (≤80%) and poor (<80%) adherence to AHA (P=0.41) and LLAs (P=0.11) were similar in the year preceding and the year following the first visit to the renal protection clinics. Conclusion: Our results suggest that referral and follow-up in a renal protection clinic may increase the prescription of cardioprotective agents in CKD patients, but does not appear to improve adherence to these medications.
