Medication Adherence 

Improving medication use outcomes: Medication adherence and other strategies

ISSUE: As we reorganize our health system to meet the Triple Aim [1], how do we maximize the pharmacist’s contributions to appropriate, safe, and cost-effective medication use (including medication adherence)? 

RECOMMENDATION: The contributions of medication management, including adherence, to the Triple Aim of a reorganized healthcare system can be amplified through the integration of comprehensive pharmacist services at the individual patient and population levels. 

CURRENT LAW: Currently, federal law does not explicitly address medication adherence. Federal law addressing health professions education is found at 42 USC 293 et seq. Federal law addressing payment to providers for the delivery of services to Medicare beneficiaries, in particular the definition of those providers and services, is found at 42 USC 1395 et seq. 

BACKGROUND: Over the past decade, attention to the problem of medication adherence has escalated in the United States and globally. The World Health Organization published a report in 2003 on medication adherence, noting that approximately 50% of patients with chronic illnesses in developed countries do not take that their medications as prescribed [2]. In the United States, up to 2/3 of medication related hospital admissions [3] are a result of medication non-adherence costing the US health care system 100 to 289 billion dollars annually [4]. Consequently in response, a ground swell of action across healthcare policy, payment and patient organizations has resulted, including steps taken by the Institute of Medicine, AHRQ, the Partnership for Patients, the pharmaceutical industry, the Centers for Medicare and Medicaid Services and multi-organization collaborations such as the Pharmacy Quality Alliance and Script Your Future [4,5,6,7,8,9].

Adherence to medications is an important part of improving health outcomes [10]. Positive health outcomes depend on accurate diagnostic ability, selection of appropriate medical treatment, patient adherence and persistence with the established treatment plan and sufficient follow-up and monitoring. Pharmacy education prepares pharmacists whose competencies include the ability to improve patient outcomes through the provision of a broad range of medication management services [11].

The American Association of Colleges of Pharmacy recognizes that strategies  to achieve desired outcomes associated with medication management services, including medication adherence, require a pharmacist who  is culturally competent; is able to communicate effectively with patients, their care givers and providers; and provides person-centered and team-based, collaborative care [12].

Ultimately, the ability to improve medication use outcomes requires a comprehensive approach to medication management of which medication adherence is one strategy [13]. Effective medication management is a shared responsibility between the patient and their providers.  Providers need to ascertain the reasons for non-adherent behaviors and help patients overcome any personal challenges with medication adherence.

Pharmacists may prove to be the most accessible and knowledgeable health professional to help patients with poor medication adherence. Assessing and managing medication adherence is a major role for pharmacists [14,15]. Evidence supports the efficacy of pharmacists providing these services [16,17]. Yet, tackling non-adherence and its complexities requires a team approach. Pharmacists will need to work closely with patients, their families or caregivers, and health care providers. Tools to facilitate this coordination of care include medication refill notices that can be reported back to providers with EMRs, encrypted secure e-mail systems, and codes that allow a pharmacist to transmit a patient medication adherence assessment to an emergency room physician [18]. Effective management of patient and population medication outcomes will require a broad set of strategies of which medication adherence is just a start.
