Association Among Change in Medical Costs, Level of Comorbidity, and Change in Adherence Behavior

Steven M. Kymes, PhD; Richard L. Pierce, PhD; Charmaine Girdish, MPH; Olga S. Matlin, PhD; Troyen Brennan, MD, JD, MPH; and William H. Shrank, MD, MSHS
The authors found that comorbidity burden and the direction of behavioral change influence the relationship between adherence and medical spend. This could affect the cost-benefit considerations of medication adherence programs.
Fourth, in our analyses, we have focused exclusively on the financial impact of medication adherence on payers, ignoring the detrimental impact that medication nonadherence might have on the quality of life of the patient or their family. However, we conducted these analyses from the payer’s perspective—as it is the payer who makes coverage decisions in the United States—and there is considerable heterogeneity in the way that quality-of-life information is used by payers, as well as a multiplicity of quality-of-life measures used, even for the 3 conditions considered here. Thus, it is not clear how to properly measure quality of life related to medication adherence in a manner meaningful to a payer, or how meaningful the results might be for them. Therefore, we have taken the more conservative approach of considering only the financial impact, which might be considered the lower bound of potential impact of a change in adherence behavior. Finally, we have addressed the consequence of changes in adherence behavior and the importance of persistency, but we have not spoken to the long-term impact of the 40% of the cohort members who remained nonadherent. Finding methods to move these patients to healthy behaviors remains an essential and intractable public health challenge.

CONCLUSIONS

Medication adherence is a critical health problem worldwide. Resolving it requires careful targeting of effective programs, and one element of that targeting criteria must be the value of adherence to the patient and payer. What we have demonstrated will vary with the direction of adherence behavior change and the comorbid conditions; thus, thoughtful policy makers, investigators, and clinicians should take these factors into consideration when implementing their adherence programs.
