CKD Quality Initiative Program
• To assess burden of CKD • (NEEDS ASSESSMENT):
– Definition & classification – Assess prevalence of co-morbid conditions
• To assess the implementation of EBM • (IDENTIFY BEST PRACTICES)
– Screening and follow-up – Hypertension, Diabetes, Bone-mineral metabolism – Pre-ESRD care (vascular access)
• To identify barriers in adherence to EBM • (FIND WAYS TO IMPLEMENT THEM AND ASSESS IMPACT)
– Patient related factors – Processes of care factors

Calculating Adherence
15 days
Truncated for study period
• Medication Adherence (MA) was derived from medication possession ratio (MPR)
• MPR = Actual Treatment Days / Total Possible Treatment Days • Possible treatment days truncated for study period and deaths • Good MA = MPR ≥ 0.8; Poor MA = MPR < 0.8
Medication available from 4/10 to 7/1 (81 days) Patient refilled 2nd fill late, missed 15 days of medication. Patient had medication for 66 of 81 possible days. MPR = 66/81 = 0.81
