The Rate of Adherence to Antiarthritis Medications and Associated Factors among Patients with Rheumatoid Arthritis: A Systematic Literature Review and Metaanalysis

Adherence to the antirheumatic drugs: a systematic review and meta-analysis

Introduction

This systematic review and meta-analysis aimed to analyze the adherence rate for conventional and biological disease-modifying antirheumatic drugs (DMARDs) utilizing different assessment measures.

Method

A systematic literature search was performed in four electronic databases, including PubMed, Scopus, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL), covering the time frame from April 1970 to April 2023. Studies that present data on medication adherence among adult patients with rheumatoid arthritis (RA), specifically focusing on DMARDs (conventional or biological), were included in the analysis. The adherence rate for different assessment measures was documented and compared, as well as for conventional and biological DMARDs. A random-effects meta-analysis was performed to assess adherence rates across different adherence assessment measures and drug groups.

Results

The search identified 8,480 studies, out of which 66 were finally included in the analysis. The studies included in this meta-analysis had adherence rates ranging from 12 to 98.6%. Adherence rates varied across several adherent measures and calculation methods. Using the subjective assessment measures yielded the outcomes in terms of adherence rate: 64.0% [0.524, 95% CI 0.374-0.675] for interviews and 60.0% [0.611, 95% CI 0.465-0.758] for self-reported measures (e.g., compliance questionnaires on rheumatology CQR-5), p > 0.05. In contrast, the objective measurements indicated a lower adherence rate of 54.4% when using the medication event monitoring system (p > 0.05). The recorded rate of adherence to biological DMARDs was 45.3% [0.573, 95% CI 0.516-0.631], whereas the adherence rate for conventional DMARDs was 51.5% [0.632, 95% CI 0.537-0.727], p > 0.05. In the meta-regression analysis, the covariate "Country of origin" shows a statistically significant (p = 0.003) negative effect with a point estimate of -0.36, SE (0.12), 95% CI, -0.61 to -0.12.

Discussion

Despite its seemingly insignificant factors that affect the adherence rate, this meta-analysis reveals variation in adherence rate within the types of studies conducted, the methodology used to measure adherence, and for different antirheumatic drugs. Further research is needed to validate the findings of this meta-analysis before applying them to clinical practice and scientific research. In order to secure high reliability of adherence studies, compliance with available reporting guidelines for medication adherence research is more than advisable.

Medication adherence and predictive factors among patients with rheumatoid arthritis: A COM-B model guided structural equation modeling analysis

OBJECTIVE

To assess medication adherence of patients with rheumatoid arthritis (RA) and explore predictive factors under the guidance of the Capability, Opportunity and Motivation to Behavior (COM-B) model.

METHODS

A cross-sectional study was conducted among 221 RA patients conveniently recruited from rheumatology outpatient clinics of a university-affiliated hospital in China. Data about patients' sociodemographic and disease characteristics, medication adherence, functional disability, social support, beliefs about medicines, self-efficacy, and depression were collected via self-administered questionnaires. The influence of factors within the COM-B model on medication adherence were analyzed by the structural equation model.

RESULTS

The mean score of medication adherence was 63.19 (SD 8.83), and 214 participants (96.8%) were considered non-adherent to their medication regime. Greater functional disability, higher social support, more positive beliefs about medicines, higher self-efficacy, and lower depression were significantly positively associated directly or indirectly with medication adherence, explaining 66% of the total variance.

CONCLUSION

Patients with RA demonstrate poor medication adherence. Essentials in improving medication adherence are delaying the occurrence of disability, promoting social support, shaping beliefs about medicines, enhancing self-efficacy, and relieving depression.

PRACTICE IMPLICATIONS

The value of integrated interventions targeting the drivers and barriers to medication adherence identified in this study should be further explored.

Socioeconomic Status and Medication Use in Rheumatoid Arthritis: A Scoping Review

OBJECTIVE

Socioeconomic status (SES) influences disease outcomes in rheumatoid arthritis (RA) patients. Differences in medication use may partly explain this association. A scoping review was used to identify research conducted on this topic and determine what knowledge gaps remain.

METHODS

Medline, Embase, and PsychInfo were searched from their inception until February 2022 for studies that assessed SES and medication use as an outcome variable. Data was extracted on the use of specific SES measures, medication use, and whether differences in SES variables were associated with differences in medication use.

RESULTS

We identified 2,103 studies, of which 81 were selected for inclusion. Included studies originated most frequently from the US (42%); the mean ± SD age of participants was 55.9 ± 6.8 years, and most were female (75%). Studies measured a median of 4 SES variables (interquartile range 3-6), with educational, area-level SES, and income being the most frequent measurements used. Patients' race and/or ethnicity were documented by 34 studies. Studies primarily assessed the likelihood of prescription of disease-modifying antirheumatic drugs or dispensation, medication adherence, or treatment delays. A majority of studies documented at least 1 SES measure associated with a difference in medication use.

CONCLUSION

There is some evidence that SES affects use of medications in patients with RA; however, multiple definitions of SES have been utilized, making comparisons between studies difficult. Prospective studies with consistently defined SES will be needed to determine whether differences in medication use accounts for the poorer outcomes experienced by patients of lower SES.

Adherence to methotrexate and associated factors considering social desirability in patients with rheumatoid arthritis: a multicenter cross-sectional study

BACKGROUND

Assessing medication adherence in rheumatoid arthritis (RA) is clinically significant as low adherence is associated with high disease activity. Self-reported medication adherence surveys have been shown to have problems with overestimation of adherence due to social desirability bias. However, no MTX adherence studies adjusted for social desirability have been conducted to date. This study aimed to evaluate adherence to MTX and perform an investigatory search for factors associated with MTX adherence including social desirability.

METHODS

This cross-sectional multicenter study was conducted among adult RA patients consuming oral MTX for ≥ 3 months. We examined the distribution of MTX adherence, according to the eight-item Morisky Medication Adherence Scale (MMAS-8). Social desirability was using the Social Desirability Scale (SDS). Furthermore, an exploratory factor analysis involving social desirability was examined to identify factors associated with MTX adherence using linear regression analysis. To deal with missing values, we used multiple imputations with chained equations methods.

RESULTS

A total of 165 RA patients were enrolled. The median age was 64 years, and 86.1% were women. Based on the MMAS-8, low, medium, and high adherences were noted in 12.1%, 60.0%, and 27.9% of participants, respectively. High social desirability (coefficient, 0.14; 95% confidence interval [CI], 0.05-0.23; p < 0.05) and high age (coefficient per 10 years, 0.16; 95% CI, 0.01-0.03; p < 0.05) were associated with high MTX adherence, whereas full-time work was negatively associated with high MTX adherence (coefficient, -0.50; 95% CI, -0.95--0.05; p < 0.05).

CONCLUSIONS

A large proportion of patients with RA do not take MTX as prescribed. High social desirability, high educational level, and non-full-time work may be associated with high MTX adherence. Physicians should confirm MTX adherence before switching or adding disease-modifying anti-rheumatic drugs in cases of uncontrolled disease activity.

Gaming for Adherence to Medication using Ehealth in Rheumatoid arthritis (GAMER) study: a randomised controlled trial

Objective

To examine the effect on adherence to disease modifying anti-rheumatic drugs (DMARDs) in participants with rheumatoid arthritis (RA) of a serious game that targeted implicit attitudes toward medication.

Methods

A multicentre randomised controlled trial (RCT) was performed with adults with RA that used DMARDs and possessed a smartphone/tablet. Control and intervention groups received care as usual. The intervention group played the serious game at will during 3 months. Game play data and online questionnaires Compliance Questionnaire on Rheumatology (CQR), Beliefs about Medicine Questionnaire (BMQ), Health Assessment Questionnaire (HAQ) and Rheumatoid Arthritis Disease Activity Index (RADAI) were collected. Primary outcome was DMARD implementation adherence operationalised as the difference in proportion of non-adherent participants (<80% taking adherence) between intervention and control group after 3 months using a Chi-squared test. Two sample t-tests and Wilcoxon rank-sum test were performed to test for differences on secondary outcomes.

Results

Of the 110 intervention participants that started the study, 87 participants (79%) installed the game and had a median playtime of 9.7 hours at 3 months. Overall, 186 participants completed the study. Adherence in intervention group (63%) and control group (54%) did not differ significantly (p=0.13) at 3 months. Neither were there differences oberved in CQR continuous score, beliefs about medication (BMQ) or clinical outcomes (HAQ and RADAI).

Conclusion

A serious game aimed at reinterpreting attitudes toward medication failed to show an effect on adherence to DMARDs or clinical outcomes in patients with RA. The game was played frequently indicating that it can be an effective channel for reaching patients.

Mesenchymal Stem Cell-Derived Extracellular Vesicles as Non-Coding RNA Therapeutic Vehicles in Autoimmune Diseases

Autoimmune diseases (ADs) are characterized by the activation of the immune system against self-antigens. More common in women than in men and with an early onset, their incidence is increasing worldwide, and this, combined with their chronic nature, is contributing to an enlarged medical and economic burden. Conventional immunosuppressive agents are designed to alleviate symptoms but do not constitute an effective therapy, highlighting a need to develop new alternatives. In this regard, mesenchymal stem cells (MSCs) have demonstrated powerful immunosuppressive and regenerative effects. MSC-derived extracellular vesicles (MSC-EVs) have shown some advantages, such as less immunogenicity, and are proposed as novel therapies for ADs. In this review, we summarize current perspectives on therapeutic options for ADs based on MSCs and MSC-EVs, focusing particularly on their mechanism of action exerted through their non-coding RNA (ncRNA) cargo. A complete state-of-the-art review was performed, centralized on some of the most severe ADs (rheumatoid arthritis, autoimmune type 1 diabetes mellitus, and systemic lupus erythematosus), giving evidence that a promising field is evolving to overcome the current knowledge and provide new therapeutic possibilities centered on MSC-EVs and their role as ncRNA delivery vehicles for AD gene therapy.

The Effects of Patient Education on Psychological Status and Clinical Outcomes in Rheumatoid Arthritis: A Systematic Review and Meta-Analysis

Background

Rheumatoid arthritis (RA) is a common systemic inflammatory autoimmune disease. The disease has a serious impact on mental health and requires more effective non-pharmacological interventions.

Objective

This study aims to systematically evaluate the effectiveness of patient education on psychological status and clinical outcomes in rheumatoid arthritis.

Methods

This systematic review and meta-analysis was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Cochrane Library, EMBASE database, and Web of Science database were screened for articles published until November 2, 2021. Randomized controlled trials (RCTs) of patient education for RA were included. Outcomes measures included pain, physical function, disease activity, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), anxiety, depression, Arthritis Self-Efficacy (pain, other symptoms, total), and General health. For each outcome, standardized mean differences or mean differences and 95% confidence intervals (CIs) were calculated.

Results

A total of 24 RCTs (n = 2,276) were included according to the inclusion and exclusion criteria. Meta-analysis revealed a statistically significant overall effect in favor of patient education for physical function [SMD = -0.52, 95% CI (-0.96, -0.08), I 2 = 93%, P = 0.02], disease activity [SMD = -1.97, 95% CI (-3.24, -0.71), I 2 = 97%, P = 0.002], ASE (pain) [SMD = -1.24, 95% CI (-2.05, -0.43), I 2 = 95%, P = 0.003], ASE (other symptoms) [SMD = -0.25, 95% CI (-0.41, -0.09), I 2 = 25%, P = 0.002], ASE (total) [SMD = -0.67, 95% CI (-1.30, -0.05), I 2 = 90%, P = 0.03], and general health [SMD = -1.11, 95% CI (-1.36, -0.86), I 2 = 96%, P < 0.00001]. No effects were found for anxiety [SMD = 0.17, 95% CI (-0.64, 0.98), I 2 = 82%, P = 0.68], depression [SMD = -0.18, 95% CI (-0.52, 0.15), I 2 = 52%, P = 0.28], pain [SMD = -0.37, 95% CI (-0.80, 0.05), I 2 = 89%, P = 0.08], and CRP [SMD = -0.27, 95% CI (-0.57, 0.02), I 2 = 0%, P = 0.07].

Conclusions

Patient education may be effective in improving clinical outcomes and psychological status in patients with rheumatoid arthritis. Considering the methodological limitations of the included RCTs, more high-quality and large-sample RCTs are needed to confirm this conclusion in the future.

A Serious Puzzle Game to Enhance Adherence to Antirheumatic Drugs in Patients With Rheumatoid Arthritis: Systematic Development Using Intervention Mapping

Background

Patients’ implicit attitudes toward medication need and concerns may influence their adherence. Targeting these implicit attitudes by combining game-entertainment with medication-related triggers might improve medication adherence in patients with rheumatoid arthritis (RA).

Objective

The aim of this study was to describe the systematic development of a serious game to enhance adherence to antirheumatic drugs by using intervention mapping.

Methods

A serious game was developed using the intervention mapping framework guided by a multidisciplinary expert group, which proceeded along 6 steps: (1) exploring the problem by assessing the relationship between medication adherence and implicit attitudes, (2) defining change objectives, (3) selecting evidence-based behavior change techniques that focused on adjusting implicit attitudes, (4) designing the intervention, (5) guaranteeing implementation by focusing on intrinsic motivation, and (6) planning a scientific evaluation.

Results

Based on the problem assessment and guided by the Dual-Attitude Model, implicit negative and illness-related attitudes of patients with RA were defined as the main target for the intervention. Consequently, the change objective was “after the intervention, participants have a more positive attitude toward antirheumatic drugs.” Attention bias modification, evaluative conditioning, and goal priming were the techniques chosen to implicitly target medication needs. These techniques were redesigned into medication-related triggers and built in the serious puzzle game. Thirty-seven patients with RA tested the game at several stages. Intrinsic motivation was led by the self-determination theory and addressed the 3 needs, that is, competence, autonomy, and relatedness. The intervention will be evaluated in a randomized clinical trial that assesses the effect of playing the serious game on antirheumatic drug adherence.

Conclusions

We systematically developed a serious game app to enhance adherence to antirheumatic drugs among patients with RA by using the intervention mapping framework. This paper could serve as a guideline for other health care providers when developing similar interventions.

Multilevel factors predict medication adherence in rheumatoid arthritis: a 6-month cohort study

Non-adherence challenges efficacy and costs of healthcare. Knowledge of the underlying factors is essential to design effective intervention strategies.

OBJECTIVES

To estimate the prevalence of treatment adherence in rheumatoid arthritis (RA) and to evaluate its predictors.

METHODS

A 6-month prospective cohort study of patients with RA selected by systematic stratified sampling (33% on first disease-modifying rheumatic drug (DMARD), 33% on second-line DMARD and 33% on biologics). The outcome measure was treatment adherence, defined by a score greater than 80% both in the Compliance Questionnaire in Rheumatology and the Reported Adherence to Medication scale, and was estimated with 95% CIs. Predictive factors included sociodemographic, psychological, clinical, drug-related, patient-doctor relationship related and logistic. Their effect on 6-month adherence was examined by multilevel logistic models adjusted for baseline covariates.

RESULTS

180 patients were recruited (77% women, mean age 60.8). The prevalence of adherence was 59.1% (95% CI 48.1% to 71.8%). Patients on biologics showed higher adherence and perceived a higher medication need than the others; patients on second-line DMARDs had experienced more adverse events than the others. The variables explaining adherence in the final multivariate model were the type of treatment prescribed (second-line DMARDs OR=5.22, and biologics OR=3.76), agreement on treatment (OR=4.57), having received information on treatment adaptation (OR=1.42) and the physician perception of patient trust (OR=1.58). These effects were independent of disease activity.

CONCLUSION

Treatment adherence in RA is far from complete. Psychological, communicational and logistic factors influence treatment adherence in RA to a greater extent than sociodemographic or clinical factors.

Patients' Characterization of Medication, Emotions, and Incongruent Perceptions around Adherence

Medication nonadherence is prevalent among patients with chronic diseases. Previous research focused on patients’ beliefs in medication or illness and applied risk-benefit analyses when reasoning their behavior. This qualitative study examined rheumatoid arthritis (RA) patients’ perceptions and feelings toward medication in parallel with attitudes about their own adherence. We conducted four 90-min focus groups and seven 60-min interviews with a diverse sample of RA patients (n = 27). Discussions covered dilemmas encountered, emotions, and thought process concerning medication, and included application of projective techniques. Transcripts were analyzed in NVivo-12 using a thematic coding framework through multiple rounds of deduction and categorization. Three themes emerged, each with mixed sentiments. (1) Ambivalent feelings toward medication: participants experienced internal conflicts as their appreciation of drugs for relief contradicted worries about side effects or “toxicity” and desire to not identify as sick, portraying medications as “best friend” and “evil”. (2) Struggles in taking medication: participants “hated” the burden of managing regimen and resented the reliance and embarrassment. (3) Attitudes and behavior around adherence: most participants self-reported high adherence yet also described frequently self-adjusting medications, displaying perception-action incongruency. Some expressed nervousness and resistance while others felt empowered when modifying dosage, which might have motivated or helped them self-justify nonadherence. Only a few who deviated from prescription discussed it with their clinicians though most participants expressed the desire to do so; open communication with providers reinforced a sense of confidence and control of their own health. Promoting personalized care with shared decision-making that empowers and supports patients in managing their long-term treatment could encourage adherence and improve overall health outcome.

Patients' perspectives on medication for inflammatory bowel disease: a mixed-method systematic review

Inflammatory bowel disease (IBD) is a lifelong chronic disease that frequently requires long-term medical treatment to maintain remission. Patient perspectives on IBD medication are important to understand as nonadherence to IBD medication is common. We aim to synthesize the evidence about patients' perspectives on medication for IBD. A mixed-method systematic review was conducted on Scopus, EMBASE, Web of Science, and CINAHL. The convergent integrated approach to synthesis and integration of qualitative and quantitative findings was used for data analysis. Twenty-five articles from 20 countries were included in this review (20 quantitative, 3 qualitative, and 2 mixed-method studies). Patients have identified a lack of knowledge in the areas of efficacy, side effects, and characteristics of medications as key elements. Some negative views on IBD medication may also be present (e.g. the high number of pills and potential side effects). Lack of knowledge about medication for IBD was identified as a common issue for patients. Health services delivery for IBD should take into consideration these patients' perspectives. A focus on improving patient education in these areas could help empower patients and alleviate doubts resulting in better disease management and improved healthcare outcomes.

Treatment expectations as a possible prognostic factor for DMARD response in rheumatoid arthritis: a prospective cohort study

Background:

The prediction of the individual’s response to disease modifying antirheumatic drugs (DMARDs) in rheumatoid arthritis (RA) is challenging and often limited. Here we evaluated the influence of patients’ expectations towards a change in treatment with DMARD on clinical outcome in RA.

Methods:

One hundred patients (74 female) with RA (2010 ACR/EULAR classification criteria) and an upcoming change in DMARD treatment due to non-response or adverse effects were included. Patients’ treatment beliefs, health-related quality of life and treatment expectations were measured using the Beliefs about Medicines Questionnaire (BMQ), the Short Form 36, and self-designed questions about expectations before treatment initiation (T0), and DAS28-CRP was calculated at T0 and after 4 months (T4). Associations between patients’ beliefs and expectations and changes in DAS28-CRP (T0 to T4, ΔDAS28-CRP) were explored by regression analyses after multiple imputation.

Results:

A total of 99 patients were included, of whom 84 completed all questionnaires. Thirty-six percent of all variability in treatment response (ΔDAS28-CRP) was explained by expectations assessed with the questionnaires and the C-reactive protein (CRP)-value at T0. Among these, the expected improvement rate, with 10.5%, as well as the CRP-value at T0, with 10.6%, had the greatest positive effect whereas the fear of adverse effects, with 11.4%, and the BMQ.concern scale, with 9.0%, had the greatest negative impact on ΔDAS28.

Conclusion:

Patients’ expectations towards newly induced DMARD therapies influence clinical response and may serve as possible explanatory factors for treatment response affecting subjective and objective outcome parameters.

Markers of disease severity and positive family history are associated to significant risk perception in rheumatoid arthritis, while compliance with therapy is not: a cross-sectional study in 415 Mexican outpatients

BACKGROUND

Assessing risk perception (RP) helps explain how rheumatoid arthritis (RA) patients integrate their ideas concerning the disease and how this understanding affects their self-care management. Compliance with treatment impacts disease-related outcomes and could be associated with RP to variable degrees and at different levels. The primary objective was to determine a potential association between RP and compliance with therapy in RA outpatients and to identify additional factors. The secondary objective was to identify factors associated with judgment bias such as unrealistic RP.

PATIENTS AND METHODS

Between January 2018 and June 2019, 450 consecutive outpatients who received RA-related treatment were invited to a face-to-face interview to obtain socio-demographic data, RA-related information, comorbidities, and the following outcomes: adherence, persistence, and concordance with medications assessed with a questionnaire locally designed; RP with the RP questionnaire (RPQ); disease activity with the Routine Assessment of Patient Index Data-3 (RAPID-3); disability with the Health Assessment Questionnaire Disability Index (HAQ-DI); quality of life with Medical Outcomes Study Short Form-36 (SF-36) instrument; pain and overall disease with the respective visual analogue scale (VAS); and health literacy assessed with 3 questions. Significant RP was defined according to a cut-off based on the 75th percentile value of the sample in which the RPQ was validated. Unrealistic RP was defined based on the coincidence of the presence/absence of significant RP and less/more than 7 unfavorable medical criteria. Multiple logistic regression analysis was used. Patients provided written informed consent and the study received Internal Review Board approval.

RESULTS

There were 415 patients included, primarily middle-aged women with long-standing disease and moderate disease activity. Almost half of the patients were receiving corticosteroids and 15.9% intensive RA-related treatment. There were 44.1% of the patients concordant with treatment and 22.6% had significant RP. The patients' treatment behavior was not retained in the regression analysis; meanwhile, rheumatoid nodes, surgical joint replacement, family history of RA, and higher RAPID-3 score were associated with significant RP. There were 56 patients with unrealistic RP; significant RP and more unfavorable medical criteria were associated with unrealistic RP.

CONCLUSIONS

Compliance with therapy was not associated with significant RP in RA outpatients.

Benefits of Switch from Oral to Subcutaneous Route on Adherence to Methotrexate in Patients with Rheumatoid Arthritis in Real Life Setting

PURPOSE

The purpose of the APRIM study (for Adherence Polyarthrite Rhumatoïde Injection Methotrexate) was to investigate the change in treatment adherence of patients with rheumatic arthritis (RA) who switched from oral to subcutaneous methotrexate (MTX).

PATIENTS AND METHODS

Prospective, observational study in RA patients treated with MTX and switching from oral to subcutaneous (SC) route in real-life conditions. Data on motivations for switch, disease activity (DAS28-CRP), quality of life (AISM-2 SF), disability (HAQ-DI), and adherence to MTX were collected at inclusion (M0) and 6 months later (M6). Adherence was assessed by the 8-item Morisky Medication Adherence Scale (MMAS-8) and defined as high (MMAS-8 = 8), medium (MMAS-8 = 6 or ≤8) or low (MMAS-8 < 6). The primary evaluation criterion was the proportion of patients who maintained strong adherence or improved adherence by at least one category (from low to medium or strong or from medium to strong) between M0 and M6.

RESULTS

The analysis involved 207 patients (age 60.4±12.7 years, 75.2% females). 6.7% were in remission and 15.5% had low disease activity (LDA) at baseline. 58.5% reached the primary criterion and strong adherence rate increased from 42.0% to 50.7%. Change of route was combined with increased MTX dose in 34.8% of patients. Switch to SC route increased the proportion of patients with remission or LDA from 22.8% to 52.9% and increased quality of life even in patients with unchanged MTX dose.

CONCLUSION

Overall, change from oral to SC route improved adherence to MTX, RA control and quality of life independently of change in MTX dose.

Adherence to Treatment in Patients with Rheumatoid Arthritis from Spain

OBJECTIVE

To evaluate adherence to treatment in a cohort of patients with rheumatoid arthritis in Spain and to identify potential predictors of adherence.

METHODS

An observational, cross-sectional, multicenter study in outpatient clinics of Rheumatology Departments from 41 centers was conducted. A validated Spanish version of the compliance questionnaire in Rheumatology was used to measure adherence in a cohort of patients with rheumatoid arthritis, representative of the Spanish population. Univariate and multivariate analyses were performed to detect predictors of adherence.

RESULTS

A total of 859 patients were recruited. An adherence rate of 79% was established. No differences were detected in adherence in patients receiving biologic disease-modifying antirheumatic drugs compared to conventional disease-modifying antirheumatic drugs, in patients receiving intravenous therapies compared to other routes of administration and in patients treated in specific day hospitals compared to polyvalent day hospitals. The number of drugs and cohabitation were independent predictors of adherence.

CONCLUSION

An inexpensive and useful method was used to measure adherence in Spanish population. The adherence rate in rheumatoid arthritis is still suboptimal. Simpler, more convenient dosing regimens may improve compliance. Increased knowledge of compliance in patients with rheumatoid arthritis and the identification of possible predictors of adherence will allow to develop effective intervention strategies.

Prevention, screening, assessing and managing of non-adherent behaviour in people with rheumatic and musculoskeletal diseases: systematic reviews informing the 2020 EULAR points to consider

OBJECTIVE

To analyse how non-adherence to prescribed treatments might be prevented, screened, assessed and managed in people with rheumatic and musculoskeletal diseases (RMDs).

METHODS

An overview of systematic reviews (SR) was performed in four bibliographic databases. Research questions focused on: (1) effective interventions or strategies, (2) associated factors, (3) impact of shared decision making and effective communication, (4) practical things to prevent non-adherence, (5) effect of non-adherence on outcome, (6) screening and assessment tools and (7) responsible healthcare providers. The methodological quality of the reviews was assessed using AMSTAR-2. The qualitative synthesis focused on results and on the level of evidence attained from the studies included in the reviews.

RESULTS

After reviewing 9908 titles, the overview included 38 SR on medication, 29 on non-pharmacological interventions and 28 on assessment. Content and quality of the included SR was very heterogeneous. The number of factors that may influence adherence exceed 700. Among 53 intervention studies, 54.7% showed a small statistically significant effect on adherence, and all three multicomponent interventions, including different modes of patient education and delivered by a variety of healthcare providers, showed a positive result in adherence to medication. No single assessment provided a comprehensive measure of adherence to either medication or exercise.

CONCLUSIONS

The results underscore the complexity of non-adherence, its changing pattern and dependence on multi-level factors, the need to involve all stakeholders in all steps, the absence of a gold standard for screening and the requirement of multi-component interventions to manage it.

Patient and Rheumatologist Perspectives Regarding Challenges to Achieving Optimal Disease Control in Rheumatoid Arthritis

OBJECTIVE

To identify and prioritize patient- and rheumatologist-perceived barriers to achieving disease control.

METHODS

Patients with rheumatoid arthritis (RA) and rheumatologists from the Corrona registry were invited by e-mail to participate in nominal groups. Two separate lists of barriers were created, 1 from RA patient-only nominal groups and the other from rheumatologist-only nominal groups, and barriers were sorted into themes. Next, using an online survey, a random sample of RA patients from the Corrona registry were asked to rank their top 3 barriers to achieving disease control.

RESULTS

Four nominal groups totaling 37 RA patients identified patient barriers to achieving control of RA activity that were classified into 17 themes. Three nominal groups totaling 25 rheumatologists identified barriers that were classified into 11 themes. The financial aspects of RA care ranked first for both types of nominal groups, while medication risk aversion ranked second among the perceived barriers of the physician nominal group and third among those of the RA patient nominal group. Among the 450 RA patients surveyed, 77% considered RA a top health priority, and 51% reported being aware of the treat-to-target strategy for RA care; the 3 most important patient-perceived challenges to achieving disease control were RA prognosis uncertainty, medication risk aversion, and the financial/administrative burden associated with RA care.

CONCLUSION

There are common, potentially modifiable, patient- and rheumatologist-reported barriers to achieving RA disease control, including perceived medication risk aversion, suboptimal treatment adherence, and suboptimal patient-physician communication regarding the benefits of tight control of disease activity in RA. Addressing these obstacles may improve adherence to goal-directed RA care.

Automated Text Message-Enhanced Monitoring Versus Routine Monitoring in Early Rheumatoid Arthritis: A Randomized Trial

OBJECTIVE

Frequent monitoring of patients with early rheumatoid arthritis (RA) is required for achieving good outcomes. This study was undertaken to investigate the influence of text message (SMS)-enhanced monitoring on early RA outcomes.

METHODS

We randomized 166 patients with early, disease-modifying antirheumatic drug-naive RA to receive SMS-enhanced follow-up or routine care. All patients attended visits at 0, 3, and 6 months, and a follow-up visit at 12 months. Treatment was at the physicians' discretion. The intervention included 13 SMSs during weeks 0-24 with questions concerning medication problems (yes/no) and disease activity (patient global assessment [PtGA], scale 0-10). Patients were contacted if response SMSs indicated medication problems or PtGA exceeded predefined thresholds. Primary outcome was 6-month Boolean remission (no swollen or tender joints and normal C-reactive protein levels). Quality of life (QoL; measured by the Short Form 36 survey) and Disease Activity Score in 28 joints (DAS28) were assessed.

RESULTS

Six and 12-month follow-up data were available for 162 and 157 patients, respectively. In the intervention group, 46% of the patients (38 of 82) reported medication problems and 49% (40 of 82) reported text message PtGAs above the alarm limit. Remission rates at 6 months (P = 0.34) were 51% in the intervention group and 42% in the control group. These rates were 57% and 43% at 12 months (P = 0.17) in the intervention and control groups, respectively. The respective mean ± SD DAS28 scores for the intervention and control groups were 1.92 ± 1.12 and 2.22 ± 1.11 at 6 months (P = 0.09); and 1.79 ± 0.91 and 2.08 ± 1.22 at 12 months (P = 0.28). No differences in QoL were observed.

CONCLUSION

The study did not meet the primary outcome despite a trend favoring the intervention group. This may be explained by the notably high overall remission rates.

A theory-based intervention to promote medication adherence in patients with rheumatoid arthritis: A randomized controlled trial

Introduction/objectives

Adherence to prescribed medication regimens is fundamental to the improvement and maintenance of the health of patients with rheumatoid arthritis. It is therefore important that interventions are developed to address this important health behavior issue. The aim of the present study was to design and evaluate a theory-based intervention to improve the medication adherence (primary outcome) among rheumatoid arthritis patients.

Methods

The study adopted a pre-registered randomized controlled trial design. Rheumatoid arthritis patients were recruited from two University teaching hospitals in Qazvin, Iran from June 2018 to May 2019 and randomly assigned to either an intervention group (n = 100) or a treatment-as-usual group (n = 100). The intervention group received a theory-based intervention designed based on the theoretical underpinnings of the health action process approach (HAPA). More specifically, action planning (making detailed plans to follow medication regimen), coping planning (constructing plans to overcome potential obstacles that may arise in medication adherence), and self-monitoring (using a calendar to record medication adherence) of the HAPA has been used for the treatment. The treatment-as-usual group received standard care.

Results

Data analysis was conducted based on the principle of intention to treat. Using a linear mixed-effects model (adjusted for age, sex, medication prescribed, and body mass index), the results showed improved medication adherence scores in the intervention group (loss to follow-up = 16) compared to the treatment-as-usual group (loss to follow-up = 12) at the 3-month (coefficient = 3.9; SE = 0.8) and 6-month (coefficient = 4.5; SE = 0.8) follow-up. Intervention effects on medication adherence scores were found to be mediated by some of the theory-based HAPA variables that guided the study.

Conclusion

The results of the present study support the use of a theory-based intervention for improving medication adherence among rheumatoid arthritis patients, a group at-risk of not adhering to medication regimens.

A randomized controlled trial of the Effects of a telehealth educational intervention on medication adherence and disease activity in rheumatoid arthritis patients

AIMS

To examine the effects of a tailored telehealth educational intervention on medication adherence and disease activity in discharged patients with rheumatoid arthritis (RA).

DESIGN

An un-blinded randomized controlled trial.

METHODS

A total of 92 eligible patients were recruited from January 2015-December 2015. Participants were randomly assigned to either the intervention (N = 46) or control group (N = 46). The intervention group received four educational sessions delivered through a telephone across a 12-week intervention. The content of the education mainly included: subject's knowledge about disease; treatment goals; the importance of taking medication correctly; side effect management; remembering to take medication. The control group received only standard care including discharge instructions. Outcome measures included medication adherence and disease activity.

RESULTS

The intervention group had significantly higher medication adherence compared with the control group at 12th and 24th week. There was no significant difference between two groups in disease activity at 12th and 24th week.

CONCLUSIONS

The telephone-delivered tailored educational intervention effectively improved medication adherence among discharged patients with rheumatoid arthritis. However, no significant benefits of the intervention on disease activity were detected.

IMPACT

Good medication adherence in rheumatoid arthritis patients contributes to controlling symptom and inflammation, preventing the progressive structural damage. This study demonstrated that the telehealth educational intervention could improve patients' medication adherence but did not have a direct impact on clinical condition in the short-term. The intervention for discharged patients with rheumatoid arthritis can be integrated into the clinical setting by the nursing staff as follow-up care.

Treatment Satisfaction With and Adherence to Disease-Modifying Antirheumatic Drugs in Adult Patients With Juvenile Idiopathic Arthritis

OBJECTIVE

To examine medication satisfaction and adherence and their relationships to disease variables and health-related quality of life (HRQoL) in adults with juvenile idiopathic arthritis (JIA).

METHODS

Patients (n = 96, mean age 25 years, 67% female) completed questionnaires about their health status 19 years after disease onset. Patients receiving biologic disease-modifying antirheumatic drugs (bDMARDs) or methotrexate (MTX) were assessed with the 8-item Morisky Medication Adherence Scale (MMAS-8) and the Treatment Satisfaction Questionnaire for Medication (TSQM), including dimensions of effectiveness, side effects, convenience, and global satisfaction.

RESULTS

DMARDs were received by 52 patients (54%) (mean age 25 years, 75% female), of which 28 received MTX and 37 received bDMARDs. Patients receiving combination therapy of MTX and bDMARDs (n = 15) reported higher satisfaction with bDMARDs than MTX in the dimensions of side effects and global satisfaction (mean ± SD 92.9 ± 15.5 versus 56.2 ± 30.9, and mean ± SD 67.6 ± 19.8 versus 47.1 ± 21.7; P < 0.001 and P = 0.016, respectively). Patients receiving either bDMARDs (n = 22) or MTX (n = 13) reported higher satisfaction with bDMARDs than MTX for the dimensions of effectiveness and global satisfaction (mean ± SD 78.7 ± 15.4 versus 60.2 ± 19.9, and mean ± SD 73.6 ± 17.7 versus 52.3 ± 23.9; P = 0.004 and P = 0.005, respectively). Nearly one-half of patients (46%) reported low adherence (MMAS-8 score <6) and 25% high adherence (MMAS-8 score = 8). Higher levels of pain, psychological distress, more active joints, and current MTX use were the strongest correlates of lower medication satisfaction. Perceived medication effectiveness and global satisfaction correlated positively with physical and mental HRQoL.

CONCLUSION

Patients with JIA were more satisfied with bDMARDs than MTX, and 46% reported low adherence. Higher medication satisfaction was associated with better HRQoL.

Effectiveness of pharmaceutical care for drug treatment adherence in women with lupus nephritis in Rio de Janeiro, Brazil: a randomized controlled trial

Objective

Studies have been conducted to determine the causal factors and clinical consequences of non-adherence to treatment in systemic lupus erythematosus (SLE). However, no interventions have been performed to increase drug adherence. Our objective was to assess the effectiveness of pharmaceutical care (PC) for drug treatment adherence in lupus nephritis (LN).

Methods

This was a randomized clinical trial (pragmatic trial) in patients with LN in Rio de Janeiro, Brazil, allocated in two groups: an intervention group (Dader Method for PC) and a control group (institution's usual care). Drug treatment adherence was measured by the combination of five questions normally used in clinical practice.

Results

A total of 131 patients were randomized, and 122 completed the study, with a mean follow-up of 12.7 months and use of six drugs per day and 10–12 doses per day. Low adherence was observed at baseline (intervention group: 30%; control group: 29%). PC showed 27% effectiveness (95% confidence interval (CI) –6% to 50%) in the intention to treat analysis and 31% (95% CI 0–52%) in per protocol analysis, considering all drugs. As for adherence to specific drugs for SLE, effectiveness of PC was 64% (95% CI 34–80%) with intention-to-treat analysis and 62% (95% CI 32–79%) in per protocol analysis.

Conclusions

PC was effective for increasing drug treatment adherence in SLE. The detailed account provided by the Dader Method of the difficulties with patients' drug therapy proved invaluable to approach non-adherence.

Discontinuation, persistence and adherence to subcutaneous biologics delivered via a homecare route to Scottish adults with rheumatic diseases: a retrospective study

OBJECTIVES

To understand patterns of subcutaneous (SC) biologics use over time in adults with inflammatory rheumatic musculoskeletal diseases receiving a homecare delivery service.

DESIGN

Retrospective cohort.

SETTING

Patients in secondary care receiving SC biologics in the largest Scottish Health Board.

PARTICIPANTS

A new bespoke cohort was created from routine data gathered as part of a health board Homecare Service Database. Patients over 18 years who received a supply of SC biologic from January 2012 to May 2015 with a diagnosis for rheumatoid arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS) were included.

OUTCOMES MEASURED

A standardised framework was applied by measuring discontinuation rates, persistence using Kaplan-Meier analysis and Cox regression and adherence using medication refill adherence (MRA) and compliance rate (CR).

RESULTS

751 patients were identified (AS: 105, PsA: 227, RA: 419) of whom 89.3% had more than one biologic delivery (median days' follow-up: AS: 494; PsA: 544; RA: 529) and 83.2% did not switch biologic. For all conditions, approximately half were persistent on their index biologic (52% AS, 54% PsA, 48%RA). Of patients who discontinued treatment, the majority reinitiated with the same biologic (19% AS, 18% PsA and 21% RA). Overall adherence during the period of treatment was over 80% when calculated using MRA (median %MRA: AS: 84.0%, PsA: 85.0%, RA: 82.4%) or CR (median %CR: AS: 96.6%, PsA: 97%, RA: 96.6%).

CONCLUSION

Use of linked routine data is a sustainable pathway to enable ongoing evaluation of biologics use. A more consistent approach to studying use (discontinuation, persistence and adherence metrics) should be adopted to enable comparability of studies.

Patient Perspectives on Intravenous Biologics for Rheumatologic Disease

OBJECTIVE

Two surveys were conducted with patients with rheumatologic diseases to evaluate perceptions of different routes of administration (intravenous [IV] or subcutaneous [SC]) for biologic therapy.

METHODS

In Survey I, patient preferences toward biologic treatment were evaluated at a rheumatology practice in Buffalo, New York. In Survey II, Canadian patients enrolled in the BioAdvance patient support program and scheduled to receive IV biologic therapy were asked about their opinions of IV treatment.

RESULTS

In Survey I, 243 rheumatology patients participated. Median patient age was 60 years, 76% were female, and 44% were naive to treatment with biologic agents. Among biologic-naive patients, the majority (56%) were open to either SC or IV treatment; biologic-naive women were more likely than men to express a preference for the route of administration. In Survey II, 1,598 patients from the BioAdvance program (including 306 rheumatology patients) completed the full survey. Among the rheumatology patients, the median age was 49 years, 58% were female, and 61% had not previously taken biologics before enrolling in the BioAdvance program. The median rating of IV favorability (on a 10-point scale, with higher numbers indicating increased favorability) recalled by rheumatology patients was 5 prior to their first program infusion, which increased to 9 after multiple treatment infusions.

CONCLUSION

These survey results indicate that patients with rheumatoid arthritis are generally open to IV treatment and express high satisfaction with IV therapy. Additional patient and provider education may improve shared decision-making regarding biologic therapy administration options.

How to Get the Most from Methotrexate (MTX) Treatment for Your Rheumatoid Arthritis Patient?-MTX in the Treat-to-Target Strategy

Methotrexate (MTX) is a remarkable drug with a key role in the management of rheumatoid arthritis (RA) at every stage of its evolution. Its attributes include good overall efficacy for signs and symptoms, inhibition of structural damage and preservation of function with acceptable and manageable safety, a large dose-titratable range, options for either an oral or parenteral route of administration, and currently unrivalled cost-effectiveness. It has a place as a monotherapy and also as an anchor drug that can be safely used in combination with other conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) or used concomitantly with biological DMARDs or targeted synthetic DMARDs. MTX is not without potential issues regarding toxicity, notably hepatotoxicity and bone marrow toxicity, as well as tolerability problems for some, but not all, patients. But many of these issues can be mitigated or managed. In the face of a welcome expansion in available targeted therapies for the treatment of RA, MTX looks set to remain at the foundation of pharmacotherapy for the majority of people living with RA and other inflammatory rheumatic diseases. In this article, we provide an evidence-based discussion as to how to achieve the best outcomes with this versatile drug in the context of a treat-to-target strategy for the management of RA.

Medication adherence and cost-related medication non-adherence in patients with rheumatoid arthritis: A cross-sectional study

AIM

First, to assess the clinical characteristics and medication adherence to oral rheumatoid arthritis (RA) medications in patients with RA. Second, to examine adherence determinants with a focus on the effect of medication out-of-pocket (OOP) costs on medication adherence to oral RA medications. Lastly, to examine cost-related medication non-adherence (CRN) in patients with RA.

METHODS

A cross-sectional study of patients with RA was conducted at rheumatology outpatient clinics in Shiraz, Iran. The data collection survey consisted of 5 sections including demographic questions, disease-related questions, Compliance Questionnaire Rheumatology (CQR), CRN questions and an open-ended question. SPSS version 24 was used for analysis.

RESULTS

A total of 308 completed surveys were collected. Adherence to oral RA medications was 40.3%. Just under 20% of participants were biologic disease-modifying antirheumatic drugs (bDMARDs) users and these bDMARDs users were 0.82 times less likely to be adherent to their oral RA medications compared to non-bDMARDs users (P < 0.05). There was no statistically significant association between OOP costs and adherence to oral RA medications (P > 0.05). However, 28.7% of participants reported not refilling, delaying to refill, skipping doses or taking smaller doses due to cost. In findings of the open-ended question, medication costs and affordability were the most commonly mentioned barriers to medication adherence.

CONCLUSION

Non-adherence to oral RA medications was prevalent among Iranian patients with RA and OOP costs were a barrier to medication adherence.

Effect of patient education on medication adherence of patients with rheumatoid arthritis: a randomized controlled trial

PURPOSE

There is a general understanding that patient educational interventions for enhancing medication adherence are important. However, their success at improving adherence is debatable. This study aimed to assess the influence of different modes of patient education on medication adherence in patients with rheumatoid arthritis (RA).

MATERIALS AND METHODS

One hundred and twenty RA patients with non-adherence, defined as pill count ≥80% or medication-taking behavior questionnaire for Thai patient ≥23, were randomized by block randomization and assigned in a 1:1 allocation ratio to two study arms: multi-component intervention group or single intervention group. The multi-component intervention group received 30-minute directed counseling and a disease information pamphlet. The single intervention group received only a disease information pamphlet. The primary outcomes were an improvement in an adherence rate measured by pill count after 12 weeks. The Thai Clinical Trial Registry number is TCTR20171207003.

RESULTS

After 12 weeks, the pill count adherence rate increased significantly from baseline in both study groups. In the multi-component intervention group, adherence rate increased from 92.21±14.05 to 97.59±10.07 (P=0.002) and in the single intervention group, it increased from 88.60±19.66 to 92.42±14.27 (P=0.044). However, the mean difference between the multi-component intervention group and the single intervention group was not significant (5.38±12.90 vs 3.18±14.23, P=0.531). Clinical outcomes, including disease activity score 28, EuroQoL-5D, EuroQol visual analog scale, pain score, and physician global assessment were unchanged from baseline in both groups.

CONCLUSION

Patient education significantly improved adherence. However, there were no differences between single education intervention and multi-component education intervention in improving medication adherence. Provision of a disease information pamphlet with or without directed counseling can equally enhance medication adherence of patients with RA.

Use of Auto-Injector for Methotrexate Subcutaneous Self-Injections: High Satisfaction Level and Good Compliance in SELF-I Study, a Randomized, Open-Label, Parallel Group Study

Introduction

The objective of the study was to compare compliance and acceptability of a new auto-injector (AI) versus syringe for administration of methotrexate (MTX) in patients with rheumatoid arthritis (RA).

Methods

We conducted a randomized, open-label, parallel group study comparing AI to pre-filled syringe (PFS). Adult patients with RA (ACR/EULAR 2010) receiving MTX (orally or by injection) for at least 3 months were allocated to AI or PFS for 6 months and then were allocated to AI for 6 further months. Two co-primary endpoints were defined at M6: percentage of patients with compliance at least 80%; change in functional capacity assessed by Health Assessment Questionnaire (HAQ). Secondary endpoints included quality of life (RaQoL), RA activity (DAS28), and acceptability. Local safety at injection site was assessed at each visit.

Results

Two-hundred and sixty-five patients were randomized. The main analysis was conducted on per protocol set (99 AI and 98 PFS). Compliance was 96.2% in AI and 98.9% in PFS. Good complier rates were 89.9% and 94.9%, thus a difference of − 5.0% (− 18.9%; 8.9%). HAQ remained stable in both groups. No difference was found on RaQoL, change in RA activity, and safety profile. Autonomy, acceptability, and patient satisfaction were better with AI, and patients having had the experience of both AI and PFS preferred AI (p < 0.001).

Conclusions

Although this study did not demonstrate non-inferiority of AI versus PFS, compliance was excellent in the two groups, and AI, which was preferred by patients, is a valuable alternative to PFS for administration of MTX.

Effect of medication adherence on disease activity among Japanese patients with rheumatoid arthritis

For the optimum efficacy of disease-modifying anti-rheumatic drugs (DMARDs), patients need to be adherent to their medication regimen. To clarify the effects of medication adherence on disease activity in Japanese patients with rheumatoid arthritis (RA), we conducted a cohort study in patients with various stages of RA. Patients were enrolled from the Kyoto University RA Management Alliance cohort, and followed up prospectively for 12 months. In this study, a total of 475 patients were analyzed and divided into 9 groups according to their medication adherence and the RA disease duration. The primary outcomes were based on the rate of a disease flare. The secondary outcomes were the changes in disease activity score using 28 joints (DAS28-ESR), simplified disease activity index (SDAI) and physical disability by health assessment questionnaire-disability index (HAQ). The changes in DAS28-ESR, HAQ, and the risk of disease flare in the highly adherent patients were significantly lower than those of the less adherent patients among the groups with RA ≤ 4.6 years but not those among the other groups. Taken together, this study identified a significant association between medication adherence and the disease flare during early-stage RA or short disease duration. These results emphasize the need to pay more attention to medication adherence in preventing the disease progression of RA.

FACTORS INFLUENCING THE EFFICIENCY OF THERAPY IN PATIENTS WITH RHEUMATOID ARTHRITIS: THE ROLE OF COMORBID MENTAL AND SOMATIC DISEASES

The response rate to therapy for rheumatoid arthritis (RA) rarely exceeds 60%. Mental disorders (MDs) of the anxiety-depressive spectrum (ADS) and cognitive impairment (CI) substantially affect the evaluation of the efficiency of RA therapy. Adequate psychopharmacotherapy is one of the possible approaches to optimizing the treatment of RA. The factors influencing the efficiency of RA therapy with standard disease-modifying antirheumatic drugs (DMARDs) and biological agents (BAs) in combination with adequate psychopharmacotherapy have not been previously identified. Objective: to determine the predictors of response to therapy in patients with RA receiving DMARDs and BAs with or without adequate psychopharmacotherapy for ADS disorders. Subjects and methods. The investigation included 128 patients (13% men and 87% women) with a reliable diagnosis of RA. At baseline, 75.1% of patients received DMARDs; 7.8% – BAs. ADS disorders were detected in 123 (96.1%) patients. Psychopharmacotherapy was offered to all the patients with MDs; 52 patients agreed to treatment and 71 refused. The following therapeutic groups were identified according to the performed therapy: 1) DMARDs (n = 39); 2) DMARDs + psychopharmacotherapy (n = 43); 3) DMARDs + BAs (n = 32); 4) DMARDs + BAs + psychopharmacotherapy (n = 9). The changes of MDs symptoms and the outcomes of RA were assessed in 83 (67.5%) patients at five-year follow-up. The efficiency of RA therapy was evaluated with DAS28 (EULAR criteria). Predictors of response to therapy were determined using linear regression modeling. Results and discussion. At 5 years, 22 (26.5%) and 37 (44.6%) patients were recorded to show good and moderate responses to therapy, respectively; 24 (28.9%) patients were non-respondents. The linear regression model included 14 factors (p<0.001). The high values of DAS28 (β=0.258) at the inclusion; belonging to therapeutic groups 2 (β=0.267), 3 (β=0.235), and 4 (β=0.210), the absence of diabetes mellitus (β=-0.230), and experience in using glucocorticoids (β=-0.230) were associated with a high likelihood of response to therapy; high body mass index (β=-0.200) and long RA duration (β=-0,181), a high level of rheumatoid factor (β=-0.176), a history of myocardial infarction (β=-0.153), schizotypic disorder (β=-0.132), and extra-articular manifestations of RA (β=-0.106), and older age (β=-0.102) were related to a low probability of response. The area under the ROC curve for the model was 0.99 (p><0.001). Conclusion. BA therapy and psychopharmacotherapy, along with younger age, shorter duration and high activity of RA, a low level of rheumatoid factor, lower body mass index, the absence of diabetes mellitus, myocardial infarction, and extra-articular manifestations of RA in the history, schizotypic disorder, and experience in using glucocorticoids are associated with a greater likelihood of a good and moderate treatment response.

Patients' Attitudes and Experiences of Disease-Modifying Antirheumatic Drugs in Rheumatoid Arthritis and Spondyloarthritis: A Qualitative Synthesis

OBJECTIVE

Nonadherence to disease-modifying antirheumatic drugs (DMARDS) in rheumatoid arthritis (RA) and spondyloarthritis (SpA) results in increased disease activity and symptoms and poorer quality of life. We aimed to describe patients' attitudes and experiences of DMARDs in RA and SpA to inform strategies to improve medication adherence.

METHODS

Databases (MEDLINE, Embase, PsycINFO, and CINAHL) were searched to January 2016. Thematic synthesis was used to analyze the findings.

RESULTS

From 56 studies involving 1,383 adult patients (RA [n = 1,149], SpA [n = 191], not specified [n = 43]), we identified 6 themes (with subthemes): intensifying disease identity (severity of sudden pharmacotherapy, signifying deteriorating health, daunting lifelong therapy), distressing uncertainties and consequences (poisoning the body, doubting efficacy, conflicting and confusing advice, prognostic uncertainty with changing treatment regimens), powerful social influences (swayed by others' experiences, partnering with physicians, maintaining roles, confidence in comprehensive and ongoing care, valuing peer support), privilege and right of access to biologic agents (expensive medications must be better, right to receive a biologic agent, fearing dispossession), maintaining control (complete ownership of decision, taking extreme risks, minimizing lifestyle intrusion), and negotiating treatment expectations (miraculous recovery, mediocre benefit, reaching the end of the line).

CONCLUSION

Patients perceive DMARDs as strong medications with alarming side effects that intensify their disease identity. Trust and confidence in medical care, positive experiences with DMARDS among other patients, and an expectation that medications will help maintain participation in life can motivate patients to use DMARDs. Creating a supportive environment for patients to voice their concerns may improve treatment satisfaction, adherence, and health outcomes.

Medication adherence and persistence in patients with autoimmune rheumatic diseases: a narrative review

BACKGROUND

Several drugs are available for the treatment of autoimmune rheumatic diseases; however, their effectiveness may be negatively influenced by inappropriate adherence. Low adherence and persistence rates have a significant impact on patient quality of life and are associated with health-related expenses.

PURPOSE

To provide an up-to-date narrative review on treatment adherence and persistence rates, and discuss the factors that influence them, in patients with autoimmune rheumatic diseases.

MATERIALS AND METHODS

We searched the PubMed database for studies among patients with a diagnosis of rheumatoid arthritis (RA), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE), or psoriatic arthritis (PsA), published from January 2015 to February 2017. Only studies with a well-defined measurement of adherence/persistence and those that carried out an evaluation of the influencing factors were included.

RESULTS

Fifteen relevant studies that evaluated adherence and/or persistence were included. Adherence rates varied between 9.3% and 94%, and persistence rates between 23% and 80%. Most of the studies used one method to evaluate adherence or persistence (different questionnaire scores, proportion of days covered, and mean treatment duration). A high concordance was found between the adherence measurements of the Medication Event Monitoring System and Visual Analog Scale. Factors of economic, demographic, and clinical nature were only moderately linked to treatment adherence or persistence. However, patient-related factors - such as positive and increased beliefs in medication necessity, strong views of the chronic nature of the diseases, and increased knowledge of the disease - were related to better treatment adherence.

CONCLUSION

Owing to the heterogeneity of the study results, we consider that the use of more than one method to assess adherence/persistence should yield more comprehensive and accurate data about patient adherence behavior. Patient-related factors should be included and analyzed more often in adherence studies as the former may be modified to improve patient adherence.

Identification of patients at risk of non-adherence to oral antirheumatic drugs in rheumatoid arthritis using the Compliance Questionnaire in Rheumatology: an ARCO sub-study

The ARCO study (Study on Adherence of Rheumatoid Arthritis patients to SubCutaneous and Oral Drugs), a multicenter, non-interventional retrospective study, was primarily designed to assess the percentage of patients [aged ≥18 years with an established rheumatoid arthritis (RA) diagnosis] with non-adherence to prescribed subcutaneous biologicals. This paper reports data for the secondary objective from a subset of patients, namely to evaluate non-adherence to prescribed oral antirheumatic drugs in RA patients in Spain using the validated Compliance Questionnaire Rheumatology (CQR). Patients also completed the Morisky-Green Medication Adherence Questionnaire, Beliefs about Medicines Questionnaire, and a questionnaire (developed and validated in Spain) on patient satisfaction with RA treatment and preferences. A total of 271 patients (76.7% females; mean age 55.6 years) were being treated with oral drugs for RA, of which 234 completed the CQR questionnaire. Non-adherence was reported in 49/234 (20.9%) patients. The proportion of non-adherence in younger patients (aged ≤48 years; 37.5%) was double that recorded in patients aged >48 years (p = 0.006). Patients with a perception of lower efficacy also had a higher risk of non-adherence (p = 0.012). Multivariable analysis showed that younger age and male gender were independently associated with risk of non-adherence. There was only slight agreement between the CQR and Morisky-Green assessment tools (kappa coefficient = 0.186), possibly reflecting the fact that both questionnaires measure slightly different aspects of medication adherence. In conclusion, one out of five RA patients was identified as at risk for non-adherence with the CQR, and this was more frequent in younger patients and in males.

Medication adherence and persistence over time with self-administered TNF-alpha inhibitors among young adult, middle-aged, and older patients with rheumatologic conditions

OBJECTIVE

Self-injectable TNF inhibitors are increasingly used early in the chronic treatment of moderate to severe rheumatologic conditions. We estimated medication adherence/persistence over time following initiation in young adult and older adult patients with rheumatoid arthritis, ankylosing spondylitis or psoriatic arthritis.

METHODS

We conducted a retrospective cohort study of patients aged 18+ years newly initiating etanercept, adalimumab, certolizumab pegol, or golimumab using the Truven Health MarketScan Database between 2009 and 2013. Pharmacy dispensing data were used to calculate 12-month medication possession ratios (MPR) and determine adherence (MPR ≥ 0.80) for up to 3 years after starting therapy. Persistence over each 12-month interval was defined as not having a ≥92-day treatment gap. Multivariable generalized estimating equation models were used to calculate odds ratios (OR) and robust 95% confidence intervals (CI) for associations between patient characteristics and repeated adherence/persistence measures over time.

RESULTS

Among 53,477 new users, 14% were young adults (18-34 years), 49% middle-aged (35-54 years), and 37% older adults (55+ years). Overall, 37% of patients were adherent and 83% were persistent in the first year of therapy. The lowest adherence (17%) and persistence (70%) were observed among young adult patients by Year +3. Compared to older adults, middle-aged (OR = 0.73, 95% CI: 0.71-0.76) and young adults (OR = 0.50, 95% CI: 0.47-0.53) were less likely to be adherent. Higher Charlson comorbidity scores, hospitalizations, and emergency department visits were associated with non-adherence/non-persistence.

CONCLUSIONS

We observed low adherence to self-administered TNF inhibitors but most patients remained persistent over time. Further efforts to improve adherence in young adults and patients with greater comorbidity are needed.
