ABSTRACT Nonadherence with medication treatment has been found to occur in large proportions of patients with a broad range of chronic conditions. Our aim was to perform a systematic review of the literature examining adherence with treatments for inflammatory rheumatic conditions to assess the magnitude of the problem in this patient population.
A MEDLINE search of English language literature was performed to identify studies published between January 1, 1985 and November 30, 2007 that evaluated adherence with chronic medications needed in the treatment of rheumatic conditions.
A total of 20 articles met the criteria for evaluation, the majority of which focused on the treatment of rheumatoid arthritis. Most of the studies examined the use of nonsteroidal anti-inflammatory medications and disease-modifying antirheumatic drugs. Adherence was assessed based on self-report, pill counts, pharmacy dispensings, openings of pill containers using electronic devices, laboratory assays, and physician assessment. Adherence varied greatly based on the adherence measure used, arthritic condition evaluated, and medication under study. Overall, the highest rates of adherence were based on self-reports for a wide variety of medications and conditions (range of persons reporting adherence was 30 to 99%), while the lowest adherence rates were for allopurinol based on pharmacy dispensings (18-26%).
Adherence has not been widely examined for most chronic inflammatory rheumatic conditions and the few studies that exist used different definitions and populations, thus limiting any conclusions. However, the current literature does suggest that nonadherence is a substantial problem.

    ABSTRACT: There are ways to integrate culturally competent services (CCS) and evidence-based practices (EBP) which can improve the experiences of patients and their families and communities when faced with health problems, as well as the effectiveness and positive experiences of practitioners. CCS and EBP evidence should be jointly deployed for helping patients and clinicians. Partnership research models are useful for achieving the integration of CCS and EBP, since they involve close observation of and participation by clinicians and practitioners in the research process, and often use integrated qualitative and quantitative mixed methods. We illustrate this with 3 examples of work that can help integrate CCS and EBP: ongoing collection of information from patients, clinicians and staff, or "evidence farming"; close study and continuous improvement of activities and accommodations; and use of evidence of tacit, implicit cultural scripts and norms, such as being "productive," as well as explicit scripts. From a research practice point of view, collaborative partnerships will likely produce research with culture and context bracketed in, and will contribute stronger research models, methods, and units of analysis. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    ABSTRACT: Adherence to biologic therapies among patients with rheumatoid arthritis is sub-optimal, with the proportion of adherent patients reported to be as low as 11 %. We found few studies evaluating economic outcomes, including health care costs, associated with non-adherence with biologic therapies. Findings suggest that while higher pharmacy costs drive total health care costs among adherent patients, non-adherent patients incur greater health care utilization including inpatient, outpatient, and laboratory services. Finally, economic factors are important determinants of adherence to biologics in patients with rheumatoid arthritis. Evidence to date has shown that higher out-of-pocket payments have a negative association with adherence to biologics. Furthermore, cost-related non-adherence is a highly prevalent problem in rheumatoid arthritis. Given the high costs of biologics and continued expansion of use in rheumatoid arthritis, there is need for more research to understand the economic implications of adherence to these therapies.
