Comparing Identification of Significant Non-adherence by Provider Assessment and Refill History (CMG= Continuous Multiple-interval Gap measure).Area A (circle outlined with solid border): 258 (24%) patients identified by provider as having significant non-adherence. Area B (circle outlined by dashed border): 211 (20%) patients identified by refill measure (CMG ≥20%) as having significant non-adherence. Area C (overlap of areas A and B): 79 (7%) patients identified as having significant non-adherence by both the provider assessment and refill measure (CMG). Area D (surrounding gray box): 674 patients without evidence of non-adherence by either provider assessment or refill measure (CMG), including 22 patients for whom the providers did not provide an adherence assessment by either post-visit question.
