Disagreement between pharmacy claims and direct interview to identify patients with non-adherence to chronic cardiometabolic medications
Authors' conclusion
Among patients identified as non-adherent by claims, 39.6% were observed to be adherent when assessed during pharmacist consultation. This discrepancy was largely driven by paying out-of-pocket, using alternative insurance, or medication discontinuation or change.
