ABSTRACT
Introduction: RA affecting ~ 1% of the world population, is associated with high level of non-adherence in clinical practice.The adherence to RA treatment therapy is affected by multiple factors. The present study evaluated the factors affectingadherence to medications among RA patients.Methodology: The prospective study was conducted from April 2014 to March 2015. Male and female subjects, aged≥18 years, and diagnosed with RA were included in the study. Demographic data, disease- and treatment-related data,adverse event profile and investigation data were obtained from all the participants. Adherence to medication of thesubjects was measured using adherence questionnaire. All the subjects were followed up at one month and at the end of6 months. McNemar’s test was used to analyse the difference in adherence from baseline to follow up. All the statisticalanalyses were performed using SPSS statistical software, version 17.0.Results: The study included 124 subjects, with a male to female ratio of 0.25:1, mean age of 45 years and RA duration of5 years. Mono and combination drug therapies were used in 59.1% and 41.9% of the subjects respectively. Methotrexatewas the most frequently used drug as a part of the regimen (82.3%). Among the subjects, 88 (71%) were found to beadherent. The comparison of various factors revealed significant difference only for the duration of RA (P 0.04).Conclusion: The adherence to antirheumatic medications among RA patients remains moderate and factors such asrural residence and older age (>45 years) can be associated with good adherence to RA medication. The study alsocorroborates the previous literature evidence suggesting methotrexate as the commonly used drug for managing RA.
