Background: The central goals of MTM align with those of the Chronic Care Model (CCM). However, reliable and valid assessments are needed to estimate the extent to which components of MTM care delivery are consistent with the CCM. The Assessment of Chronic Illness Care (ACIC) is a 34-item scale for administration in primary care offices to estimate the extent to which chronic care delivery aligns with the six elements of the CCM. The ACIC appears to be responsive for care delivery interventions aimed at improving various chronic illnesses. However, the potential value of the ACIC as a measure for evaluating MTM delivery is unknown.

Objective: A modified and abbreviated version of the ACIC could be a useful evaluation tool for pharmacist-provided medication therapy management (MTM). The objective of this study was to assess the construct and criterion-related validity, and internal consistency, of the abbreviated (12-item) "MTM ACIC."

Methods: The abbreviated MTM ACIC was administered to pharmacists employed at 27,560 community pharmacies. Construct validity and internal consistency were estimated through principal components analysis, item-to-total correlations, and Cronbach's alpha estimate of internal consistency. To assess criterion-related validity, a univariate negative binomial model estimated the association between ACIC scores and pharmacy-level MTM completion rates.

Results: A one-component model accounted for 64% of the variance, and Cronbach's alpha was 0.95. Scores on the abbreviated MTM ACIC were associated with MTM completion rates (rate ratio: 1.02; 95% CI: 1.01 to 1.03).

Conclusion: The abbreviated MTM ACIC exhibited acceptable construct and criterion-related validity and internal consistency and could serve as a valuable tool for evaluating chronic illness care within the MTM setting.
