OVERVIEW
With an average age at onset of approximately 30 years and a typical course that is characterized by gradually progressing irreversible disability, multiple sclerosis (MS) presents many significant treatment challenges.1 Among the most important of these challenges is helping patients to remain adherent to their long-term medication treatment with disease-modifying therapies (DMTs). Agents such as interferon ß, glatiramer acetate, and natalizumab play an important role in therapy by providing immunomodulating effects. These effects significantly reduce the frequency of MS exacerbations, and may also slow the gradual accumulation of long-term disability.2,3 Despite the benefits of DMT, adherence to treatment is an issue for many patients. A recent study, that examined adherence to interferon ß-1a (intramuscular and subcutaneous formulations) or glatiramer acetate among patients with healthcare insurance in the United States, showed a decrease in adherence of approximately 50% after only 1 year. The study also showed a low overall adherence to all of the first-line DMTs.4 Medication possession ratios, which represent the number of days of medication supply divided by the number of days in the year, were approximately 0.7 to 0.8 for the various DMTs during the first year after beginning therapy. This suggests that even patients with health insurance frequently do not administer their medication as prescribed. The obstacles that patients with MS face in adhering to their long-term treatments include the need for regular self-injection, adverse effects of treatment, insurance or other economic barriers, cognitive impairment, and depression.5
Helping patients to remain adherent to long-term therapy has increasingly been recognized as an important goal of therapy for patients with MS. A large body of research from other chronic diseases has clearly demonstrated the importance of specific factors that would improve long-term adherence to care. These factors include patient education, the patient-provider relationship, overcoming economic barriers, and medication therapy management.6 Other studies also have shown that improving adherence in patients with chronic conditions such as elevated cholesterol, type 2 diabetes, hypertension, and depression reduces overall treatment costs. These costs are reduced due to better management of complications, which decreases the need for hospitalization.7,8 Clinical researchers have just begun to examine methods that might be that adapted to the treatment of MS in order to improve adherence to treatment and therefore reduce some MS-related treatment costs.9
This University of Tennessee Advanced Studies in Pharmacy journal club module provides managed care pharmacists with brief, focused reviews of recent publications and ECTRIMS 2010 annual meeting abstracts that have examined barriers to adherence and strategies to help patients with MS obtain the greatest benefit from their treatment. The studies selected for this journal club describe how the roles of certain factors, which include disease therapy management and other programs to improve DMT adherence, the role of insurance type, out-of-pocket payments, and depression, affect patients’ adherence. These brief reviews will provide an overview of new data about the long-term management of patients with MS.
