Abstract

Medication adherence is a problem that has received widespread attention in the medical literature and health policy circles. With the increased emphasis on recognizing and rewarding quality in the U.S. health care system, medication adherence measures are increasingly being adopted to assess quality of medication use. However, when adherence is discussed in the literature or evaluated via quality measures, there is rarely any dialogue surrounding adherence in the context of patient-centered issues such as clinical status, individualized medication needs, or personal expectations and social situation. When nonadherence is identified via a comprehensive assessment of all of a patient's medication-related issues, it typically is recognized as only the third most frequent type of medication-related problem. Issues such as requiring a medication that has not been prescribed or receiving a medication prescribed at a dose too low to achieve the intended clinical goal are more frequently experienced. Furthermore, if a patient is nonadherent to a medication because of adverse effects or if the medication prescribed is not appropriate considering the patient's individual clinical situation, promoting adherence can create unintended harm. Therefore, achieving medication adherence as typically evaluated via existing quality metrics such as proportion of days covered is only valid if the medication is first deemed to be indicated, effective, and safe for the patient. Medications are the most common medical intervention for chronic illnesses. As a result, success in achieving the Triple Aim of health care is highly dependent on optimizing medication use. When quality measures for medication use narrowly focus on measuring adherence, the resulting programs of payers and providers will likely ignore the most frequent types of medication problems that prevent improved health, create unnecessary costs, and could negatively impact patients' experience with the health care system. Strong leadership and advocacy on the part of agencies in the position to influence the quality measurement landscape in the U.S. health care system will be critical to achieve widespread awareness of medication nonadherence in the context of the full scope of medication-related problems in health care.
