Facilitators and barriers to adherence in the initiation phase of Disease-modifying Antirheumatic Drug (DMARD) use in patients with arthritis who recently started their first DMARD treatment

A patient-centered evaluation of a novel medical student-based patient navigation program

OBJECTIVES

Understand the patient experience of a pilot medical student-based patient navigator (PN) program. (2) Assess areas of improvement for further development as a model for expansion.

METHODS

This was a cross-sectional study assessing patients' subjective experience of medical student navigators for rheumatological conditions. Current student navigators contacted enrolled patients by phone with both structured and free-response questions.

RESULTS

44 of 71 patients completed the questionnaire. 84% reported a satisfaction of ≥ 4 on a 5 point Likert scale. > 80% of patients felt that the program helped them better care for their health, feel more understood by their medical team, and feel cared for by their healthcare team. Medical student navigators were able to assist with most patient requests.

CONCLUSIONS

Patients enrolled in our medical student PN program expressed high levels of satisfaction and felt better able to access health resources with the help of a navigator.

PRACTICE IMPLICATIONS

Employing medical students as PNs may serve as a mutually beneficial intervention providing early clinical exposure to students while furthering patient access to care. Other institutions may benefit from similarly structured interventions.

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.

Using Twitter Data Analysis to Understand the Perceptions, Beliefs, and Attitudes about Pharmacotherapy Used in Rheumatology: An Observational Study

Twitter has become an important platform for disseminating information about rheumatology drugs by patients, health professionals, institutions, and other users. The aim of this study was to analyze tweets related to 16 drugs used in rheumatology, including their volume, content, and type of user (patients, patients' relatives, health professionals, health institutions, pharmaceutical industry, general press, scientific journals and patients' associations), and to detect inappropriate medical content. A total of 8829 original tweets were obtained, with a random sample of 25% of the total number of tweets for each drug (at least 100 tweets) analyzed. Methotrexate (MTX) accounted for a quarter of all tweets, and there were significant differences in the proportion of tweets issued according to the type of user. Patients and their relatives mainly tweeted about MTX, while professionals, institutions, and patient associations posted more about TNF inhibitors. In contrast, the pharmaceutical industry focused on IL-17 inhibitors. Medical content prevailed in all drugs except anti-CD20 and IL-1 inhibitors and the most discussed medical topic was efficacy, followed by posology and adverse effects. Inappropriate or fake content was found to be very low. In conclusion, the majority of the tweets were about MTX, which is a first-line treatment for several diseases. The distribution of medical content varied according to the type of user. In contrast to other studies, the amount of medically inappropriate content was very low.

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.

2021 clinical practice guidelines for the diagnosis, treatment, and follow-up of patients with peripheral spondyloarthritis. Colombian Association of Rheumatology

BACKGROUND

Peripheral spondyloarthritis is a chronic inflammatory disease in which clinical presentation is related to the presence of arthritis, enthesitis and/or dactylitis. This term is used interchangeably with some of its subtypes such as psoriatic arthritis, reactive arthritis, and undifferentiated spondyloarthritis.

OBJECTIVE

To develop and formulate a set of specific recommendations based on the best available evidence for the diagnosis, treatment and monitoring of adult patients with peripheral spondyloarthritis.

METHODS

A working group was established, clinical questions were formulated, outcomes were graded, and a systematic search for evidence was conducted. The guideline panel was multidisciplinary (including patient representatives) and balanced. Following the formal expert consensus method, the GRADE methodology "Grading of Recommendations Assessment, Development and Evaluation" was used to assess the quality of the evidence and generate the recommendations. The Clinical Practice Guideline includes ten recommendations; related to monitoring of disease activity (n = 1) and treatment (n = 9).

RESULTS

In patients with peripheral spondyloarthritis, the use of methotrexate or sulfasalazine as the first line of treatment is suggested, and local injections of glucocorticoids is recommended conditionally. In patients with failure to cDMARDs, an anti TNFα or an anti IL17A is recommended. In case of failure to bDMARDs, it is suggested to use another bDMARD or JAK inhibitor. In patients with peripheral spondyloarthritis associated to inflammatory bowel disease, it is recommended to start treatment with cDMARDs; in the absence of response, the use of an anti TNFα over an anti-IL-17 or an anti-IL-12-23 is recommended as a second line of treatment. In patients with psoriatic arthritis, the combined use of methotrexate with bDMARD is conditionally recommended for optimization of dosing. To assess disease activity in Psoriatic Arthritis, the use of DAPSA or MDA is suggested for patient monitoring.

CONCLUSIONS

This set of recommendations provides an updated guide on the diagnosis and treatment of peripheral spondyloarthritis.

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.

Patient's experiences of the barriers and facilitators to Methotrexate

OBJECTIVE

To investigate the barriers and facilitators of adherence to methotrexate (MTX) in people with rheumatic diseases and to explore the experience of shared decision-making.

METHODS

A qualitative study was carried out. People diagnosed with inflammatory arthritides or systemic autoimmune diseases and who were treated with MTX were invited to participate in focus groups. The discourse was coded and synthesised with a content analysis approach.

RESULTS

The groups included 12 representative patients (rheumatoid arthritis, spondylarthritis, and systemic lupus erythematosus, taking either oral or subcutaneous MTX). Four main themes were identified: (1) drug-related aspects (package insert, adverse events, administration, and difficulties with treatment); (2) patient-physician relationship; (3) social environment (lack of visibility of rheumatic diseases and the support of patient associations); and (4) medication and medical care practicalities (information, reliable sources, and expanding knowledge in other health areas).

CONCLUSIONS

Aspects identified might help improve adherence, including quality information, especially on adverse events, the role of the setting, and shared decision-making.

Qualitative Research in Rheumatology: An Overview of Methods and Contributions to Practice and Policy

Patient-centered care is widely advocated in rheumatology. This involves collaboration among patients, caregivers, and health professionals and is particularly important in chronic rheumatic conditions because the disease and treatment can impair patients' health and well-being. Qualitative research can systematically generate insights about people's experiences, beliefs, and attitudes, which patients may not always express in clinical settings. These insights can address complex and challenging areas in rheumatology, such as treatment adherence and transition to adult healthcare services. Despite this, qualitative research comprises 1% of studies published in top-tier rheumatology journals. A better understanding about the effect and role, methods, and rigor of qualitative research is needed. This overview highlights the recent contributions of qualitative research in rheumatology, summarizes the common approaches and methods used, and outlines the key principles to guide appraisal of qualitative studies.

What Are the Preferences of Patients With Rheumatoid Arthritis for Treatment Modification? A Scoping Review

OBJECTIVES

Optimal care of rheumatoid arthritis (RA) patients entails regular assessment of disease activity and appropriate adjustment of disease-modifying antirheumatic drugs (DMARDs) until a predefined treatment goal is achieved. This raises questions about the approach to treatment decision making among RA patients and their preference for associated treatment changes. We aimed to systematically identify and synthesize the available evidence of RA patients' preferences regarding DMARD modification with an emphasis on escalating, tapering, stopping, or switching of DMARDs.

METHODS

A scoping review was undertaken to gauge the breadth of evidence from the range of studies relating to RA patients' preferences for DMARD modification. Pertinent databases were searched for relevant studies published between 1988 and 2019. Conventional content analysis was applied to generate themes about how patients perceive changes to their RA treatment.

RESULTS

Of the 1730 distinct articles identified, 32 were included for review. Eight studies investigated RA patients' perceptions of switching to other DMARDs, 18 studies reported RA patients' preferences for escalating treatment, and six studies explored the possibility of tapering or stopping of biologic DMARDs. Four overarching themes relating to RA patients' preferences for treatment modification were identified: (i) patient satisfaction, (ii) patients' beliefs, (iii) information needs, and (iv) patient-clinician relationships.

CONCLUSION

Uptake of treatment changes in clinical practice can be improved by understanding how RA patients approach the decision to modify their treatment and how this relates to their satisfaction, beliefs, information needs, and relationships with clinicians. Future work is needed to systematically determine the significance of these factors in RA patients' decision-making processes.

Real-world questions and concerns about disease-modifying antirheumatic drugs (DMARDs): a retrospective analysis of questions to a medicine call center

Background

Disease-modifying antirheumatic drugs (DMARDs) have transformed the treatment of numerous autoimmune and inflammatory diseases but their perceived risk of harm may be a barrier to use.

Methods

In a retrospective mixed-methods study, we analysed conventional (c) and biologic (b) DMARDs-related calls and compared them with rest of calls (ROC) from consumers to an Australian national medicine call center operated by clinical pharmacists from September 2002 to June 2010. This includes the period where bDMARDs became available on the Pharmaceutical Benefits Scheme, the government-subsidized prescription medicines formulary. We compared caller and patient demographics, enquiry types and motivation to information-seek for both cDMARDs and bDMARDs with ROC, using a t-test for continuous data and a chi-square test for categorical data. We explored call narratives to identify common themes.

Results

There were 1547 calls involving at least one DMARD. The top three cDMARD enquiry types were side effects (27.2%), interactions (21.9%), and risk versus benefit (11.7%). For bDMARDs, the most common queries involved availability and subsidized access (18%), mechanism and profile (15.8%), and side effects (15.1%). The main consumer motivations to information-seek were largely independent of medicines type and included: inadequate information (44%), wanting a second opinion (23.6%), concern about a worrying symptom (18.8%), conflicting information (6.9%), or information overload (2.3%). Question themes common to conventional and biological DMARDs were caller overemphasis on medication risk and the need for reassurance. Callers seeking information about bDMARDs generally overestimated effectiveness and focused their attention on availability, cost, storage, and medicine handling.

Conclusion

Consumers have considerable uncertainty regarding DMARDs and may overemphasise risk. Patients cautiously assess the benefits and risks of their DMARDs but when new treatments emerge, they tend to overestimate their effectiveness.

The predictors of and reasons for non-adherence in an observational cohort of patients with rheumatoid arthritis commencing methotrexate

OBJECTIVE

In order to develop interventions to optimize MTX use for the treatment of RA we evaluated the rate of, reasons for and predictors of MTX non-adherence during the first 6 months of therapy.

METHODS

The Rheumatoid Arthritis Medication Study (RAMS) is a prospective multicentre cohort study of incident MTX users in the UK. Prior to MTX commencement demographic, clinical and psychological data were collected. A weekly patient-completed diary recorded MTX dose, possible side effects and adherence over 26 weeks. The number of non-adherent weeks was calculated. Potential baseline predictors of ever non-adherence (⩾1 week non-adherent) during the first 6 months of MTX therapy were identified using logistic regression analyses.

RESULTS

606 patients with RA were included; 69% female, mean (s.d.) age 60 (13) years and DAS28 score 4.2 (1.2). Over the first 6 months following MTX initiation, 158 (26%) patients were ever non-adherent (71% intentional, 19% non-intentional, 10% unexplained) and mean (s.d.) number of non-adherent weeks was 2.5 (2.1). Multivariable predictors of ever non-adherence included DAS28 [odds ratios (OR) 1.1, 95% CI 1.0, 1.4], fatigue (OR 1.1, 95% CI 1.0, 1.2 per cm), ⩾2 comorbidities vs no comorbidities (OR 1.9, 95% CI 1.1, 3.5) and high medication concerns despite perceived need (OR 1.1, 95% CI 1.0, 1.1 per unit decrease in need/concern differential).

CONCLUSION

This is the largest study evaluating early intentional and non-intentional non-adherence to MTX, which has identified that patient beliefs and multi-morbidity strongly link with non-adherence. These findings can direct the design of and provide potential targets for interventions to improve patient adherence.

Rheumatologists' insight into medication adherence in patients with rheumatoid arthritis: A qualitative study

BACKGROUND

Medication non-adherence is prevalent among patients with rheumatoid arthritis (RA). Rheumatologists are specialists in medication prescribing and counselling for RA, but their insights regarding medication adherence have not been studied.

OBJECTIVE

To explore rheumatologists' insights into medication adherence in patients with RA.

METHODS

A qualitative study using semi-structured interviews with 10 rheumatologists in Iran was undertaken. Thematic analysis was conducted to identify how rheumatologists assess medication adherence and their perceived determinants of adherence. The identified determinants of adherence were mapped according to the Andersen's Behavioral Model of Health Service Use.

RESULTS

Six participants were male, and the mean age was 47 years. The mean years of experience as a rheumatologist was 8.6 (SD = 7.1) years. Rheumatologists did not use a validated tool for medication adherence assessment. They assessed medication adherence either by asking their patients simple questions or using laboratory test results. The identified determinants of adherence were divided into 3 groups: patient-, rheumatologist- and healthcare organization-related determinants. The proposed suggestions to improve adherence were: (a) to understand a patient's financial situation before prescribing more expensive medications; (b) to employ a dose-reducing strategy; (c) to give hope to patients regarding remission; and (d) to arrange a session with the nurse educator.

CONCLUSION

The findings of this study provide insight into rheumatologists' perspectives on medication adherence of patients with RA. The identified determinants of adherence could be considered when developing initiatives to improve medication adherence in this group of patients.

Factors associated with medication adherence in a longitudinal study of rheumatoid arthritis patients

BACKGROUND

Identification of key determinants of medication adherence may assist with designing interventions to improve this important parameter. The aim of the study was to determine the rate and predictors of self-reported medication adherence in patients with rheumatoid arthritis (RA) over one-year follow-up.

METHODS

Socio-demographic, disease, therapy and patient-related factors were obtained from a longitudinal observational cohort of RA patients between May 2014 and June 2016. Medication adherence was measured using self-reported Compliance Questionnaire for Rheumatology (CQR) at baseline, 6 and 12 months. Mixed-effects modelling was used to investigate the relationship between adherence and potential predictors.

RESULT

Of 185 patients invited, 110 were included in the study. The median level of adherence was 71%-74% during the study period. Around 27%-30% of patients achieved > 80% adherence, while roughly one-fifth reported a CQR score within the lower quartile (CQR < 63%). After adjustment for potential confounders, increased age (β = 0.19, P = 0.010), higher self-efficacy (β = 0.89, P = 0.039) and higher medication necessity belief (β = 1.12, P < 0.0001) were associated with better self-reported adherence.

CONCLUSION

We found a moderate level of self-reported adherence over time and significant association with age, self-efficacy and medication necessity belief. The modifiable predictors of adherence found in this study can be used as a potential target for adherence-improving interventions.

Patient Perspectives on DMARD Safety Concerns in Rheumatology Trials: Results from Inflammatory Arthritis Patient Focus Groups and OMERACT Attendees Discussion

OBJECTIVE

The Outcome Measures in Rheumatology (OMERACT) Safety Working Group is identifying core safety domains that matter most to patients with rheumatic disease.

METHODS

International focus groups were held with 39 patients with inflammatory arthritis to identify disease-modifying antirheumatic drug (DMARD) experiences and concerns. Themes were identified by pragmatic thematic coding and discussed in small groups by meeting attendees.

RESULTS

Patients view DMARD side effects as a continuum and consider the cumulative effect on day-to-day function. Disease and drug experiences, personal factors, and life circumstances influence tolerance of side effects and treatment persistence.

CONCLUSION

Patients weigh overall adverse effects and benefits over time in relation to experiences and life circumstances.

I do not want to suppress the natural process of inflammation: new insights on factors associated with non-adherence in rheumatoid arthritis

BACKGROUND

It is estimated that 50-70% of patients with rheumatoid arthritis (RA) are non-adherent to their recommended treatment. Non-adherent patients have a higher risk of not reaching an optimal clinical outcome. We explored factors associated with nonadherence from the patient's perspective.

METHODS

Four hundred and fifty-nine RA patients (346 (75.4%) females; mean age 63.0 ± 14.8 years) who failed to attend follow-up visits in two rheumatology centres were eligible to participate in a qualitative interview study. We used this strategy to identify patients who were potentially non-adherent to medicines and/or non-pharmacological interventions. By means of meaning condensation analysis, we identified new and some already well known insights to factors associated with non-adherence. We used the capability, opportunity, and motivation model of behaviour (COM-B) model as a frame of reference to classify the factors.

RESULTS

Forty-three of 131 patients (32.8%) who agreed to participate in the qualitative interviews were found to be non-adherent. New insights on factors associated with non-adherence included strong opinions of patients, such as pain being considered as an indicator of hard work and something to be proud of, or inflammation being a natural process that should not be suppressed; feeling not to be in expert's hands when being treated by a physician/health professional; the experience of excessive self-control over the treatment; and rheumatologists addressing only drugs and omitting non-pharmacological aspects. The COM-B model comprehensively covered the range of our findings.

CONCLUSIONS

The new insights on factors associated with non-adherence allow a better understanding of this phenomenon and can substantially enhance patient care by helping to develop targeted interventions.

Use of rheumatology-specific patient navigators to understand and reduce barriers to medication adherence: Analysis of qualitative findings

Objective

Adherence to medications among patients with rheumatic diseases is often suboptimal. Patient navigators, individuals trained in care coordination, motivational interviewing and basic rheumatology and pharmacology, have not been employed to explore and address this issue. We piloted a single-site, single arm intervention to determine the feasibility and acceptability of using rheumatology-specific navigators to understand and reduce barriers to adherence to oral disease modifying anti-rheumatic drugs (DMARDs). We analyzed our qualitative findings from navigator-patient interactions as well as patient satisfaction with the intervention.

Methods

We recruited patients ≥18 years with a systemic rheumatic disease who initiated an oral DMARD within the prior 6 months. Navigators conducted baseline needs assessments and 2–4 week follow-up calls to understand and address issues related to medication adherence. We analyzed patient-navigator encounters qualitatively using content analysis to identify key themes related to barriers to adherence and navigator actions performed in response to the barriers described. We also categorized intentional and unintentional nonadherent behavior and assessed satisfaction with the navigator experience (range 0–5, 5 = most satisfied).

Results

107 rheumatology patients were followed for up to 6 months. Mean patient age was 55 years (+17) and 93% were female; 36% described one or more episode of intentional or unintentional nonadherence. The three most common themes identified as barriers to adherence were fear of adverse events (raised by 54%), concerns about medication effectiveness (43%), and challenges with medication acquisition (32%). 86% of participants described at least one adherence-related barrier. Frequent navigator actions included facilitation of patient-doctor communication (38%), medication and diagnosis education (27%), and development of individualized strategies to improve adherence (16%). Patients were satisfied with the navigator experience (mean 4.4 + 0.9).

Conclusion

Navigators uncovered and addressed a number of medication adherence-related concerns and patients were satisfied with the services provided.

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.

Rheumatoid Arthritis Patients' Motivations for Accepting or Resisting Disease-Modifying Antirheumatic Drug Treatment Regimens

OBJECTIVE

Patient refusal of and nonadherence to treatment with disease-modifying antirheumatic drugs (DMARDs) can adversely affect disease outcomes in rheumatoid arthritis (RA). This qualitative study describes how RA patients' feelings in response to experiences and information affected their decisions to accept (agree to adopt, initiate, and implement) or resist (refuse, avoid, and discontinue) DMARD treatment regimens.

METHODS

A total of 48 RA patients were interviewed about their experiences making decisions about DMARDs. The interviews were transcribed, coded, and analyzed for themes related to their internal motivations for accepting or resisting treatment regimens, using a narrative analysis approach.

RESULTS

In addition to feelings about the necessity and dangers of medications, patients' feelings towards their identity as an ill person, the act of taking medication, and the decision process itself were important drivers of patient's decisions. For patients' motivations to accept treatment regimens, 2 themes emerged: a desire to return to a normal life, and fear of future disability due to RA. For motivations to resist treatment regimens, 5 themes emerged: fear of medications, maintaining control over health, denial of sick identity, disappointment with treatment, and feeling overwhelmed by the cognitive burden of deciding.

CONCLUSION

Feelings in response to experiences and information played a major role in how patients weighed the benefits and costs of treatment options, suggesting that addressing patients' feelings may be important when rheumatologists counsel about therapeutic options. Further research is needed to learn how best to address patients' feelings throughout the treatment decision-making process.

Does non-adherence to DMARDs influence hospital-related healthcare costs for early arthritis in the first year of treatment?

Introduction

Non-adherence to disease-modifying antirheumatic drugs (DMARDs) is suspected to relate to health care costs. In this study we investigated this relation in the first year of treatment.

Methods

In a multi-center cohort study with a one year follow up, non-adherence was continuously measured using electronic monitored medication jars. Non-adherence was defined as the number of days with a negative difference between expected and observed opening of the container. Cost measurement focused on hospital costs in the first year: consultations, emergency room visits, hospitalization, medical procedures, imaging modalities, medication costs, and laboratory tests. Cost volumes were registered from patient medical files. We applied multivariate regression analyses for the association between non-adherence and costs, and other variables (age, sex, center, baseline disease activity, diagnosis, socioeconomic status, anxiety and depression) and costs.

Results

Of the 275 invited patients, 206 were willing to participate. 74.2% had rheumatoid arthritis, 20.9% had psoriatic arthritis and 4.9% undifferentiated arthritis. 23.7% of the patients were more than 20% non-adherent over the follow-up period. Mean costs are € 2117.25 (SD € 3020.32). Non-adherence was positively related to costs in addition to baseline anxiety.

Conclusion

Non-adherence is associated with health care costs in the first year of treatment for arthritis. This suggests that improving adherence is not only associated with better outcome, but also with savings.

Psychosocial predictors of DMARD adherence in the first three months of treatment for early arthritis

OBJECTIVES

To induce disease remission, early arthritis patients should adhere to their disease-modifying antirheumatic drugs (DMARD) in the first months after diagnosis. It remains unknown why some patients are non-adherent. We aimed to identify patients at risk for non-adherence in the first 3 months of treatment.

METHODS

Adult DMARD-naive early arthritis patients starting synthetic DMARDs filled out items on potential adherence predictors at baseline. Adherence was measured continuously. Non-adherence was defined as not opening the electronically monitored pill bottle when it should have been. Items were reduced and clustered using principal component analysis. The most discriminating items were identified with latent trait models. We used a multivariable logistic regression model to find non-adherence predictors.

RESULTS

301 patients agreed to participate. Adherence was high and declined over time. Principal component analysis led to 7 dimensions, while subsequent latent trait models analyses led to 15 dimensions. Two dimensions were associated with adherence, one dimension was associated with non-adherence.

CONCLUSIONS

Information seeking behavior and positive expectations about the course of the disease are associated with adherence. Patients who become passive because of pain are at risk for non-adherence.

PRACTICE IMPLICATIONS

Rheumatologists have cues to identify non-adherence, and may intervene on non-adherence through implementing shared decision making techniques.

Adherence to Anti-Tumor Necrosis Factor Therapy Administered Subcutaneously and Associated Factors in Patients With Rheumatoid Arthritis

BACKGROUND

Adherence to biologic therapy is relatively poorly studied in rheumatoid arthritis (RA) because many of the studies have investigated the drug persistence, which represents only a surrogate of adherence.

OBJECTIVES

The aims of this study were to determine the extent of adherence in RA patients with subcutaneously administered anti-tumor necrosis factor methotrexate agents and to identify the risk factors for nonadherence.

METHODS

A cohort of RA patients who started a subcutaneous anti-tumor necrosis factor treatment were enrolled. After 12 months of treatment, all patients completed the 4-item Morisky Medication Adherence Scale questionnaire. Associations between beliefs and nonadherence and the influence of demographic, clinical, and radiographic features were assessed using logistic regression model.

RESULTS

A total of 209 (80.4%) of the 260 patients were included in the analyses. Forty-three of 209 patients were considered nonadherent to their medication (20.6%) according to the 4-item Morisky Medication Adherence Scale. More than half (53.1%) of patients showed at least 1 form of nonadherent behavior.The logistic model showed that low disease activity (P = 0.003), higher patient-physician discordance ratings (P = 0.012), older age (P = 0.041), and a high number of comorbid conditions (P = 0.011) were significantly associated with increased likelihood of nonadherence.

CONCLUSIONS

The overall nonadherence with subcutaneous biologic therapy is relatively high among RA patients and should be taken into account when a patient's response to treatment is unsatisfactory.

Nonadherence to disease modifying antirheumatic drugs in the first year after diagnosis: comparing three adherence measures in early arthritis patients

OBJECTIVES

The aim of this study was to compare three measurement methods for non-adherence to DMARDs in early arthritis patients: the Compliance Questionnaire Rheumatology (CQR), the intracellular uptake of MTX in the form of MTX-polyglutamates (MTX-PGs) and electronic measurement with Medication Event Monitoring Systems (MEMS).

METHODS

DMARD naïve early arthritis patients were included in an ongoing cohort study. MEMS were used to measure adherence continuously, while every 3 months MTX-PGs were collected together with the CQR. The associations between the measures were estimated with Spearman rank correlations. Sensitivity and specificity of the CQR against a MEMS cut-off was compared at 3, 6, 9 and 12 months. The same applied to MTX-PGs against a MEMS cut-off and MTX-PGs against a CQR cut-off. For the association between MEMS, the CQR and MTX-PGs, a multilevel linear regression model was performed with age, gender, weeks of treatment and MTX dosage as covariates.

RESULTS

We included 206 patients. Non-adherence measured with MEMS varied over time and between DMARDs. The CQR score was not associated with MEMS non-adherence at 3, 9 and 12 months. At 9 months, MTX-PGs was associated with MEMS non-adherence, as well as with the CQR. All correlations were below 0.30.

CONCLUSION

Associations between the three measures are weak. Explanations are individual differences in the uptake of MTX, and little variance in adherence between patients. Moreover, the measurement domains differ: perceptions (CQR), behaviour (MEMS) and pharmacokinetics (MTX).

'The lesser of two evils…' - views of persons with rheumatoid arthritis on medication adherence: a qualitative study

OBJECTIVE

This study aimed to explore medication adherence among adherent and non-adherent persons suffering from rheumatoid arthritis (RA). A special focus was put on the reasons accounting for successful medication adherence and on potential barriers or facilitating factors.

DESIGN

A qualitative study with semi-structured interviews was conducted. Eighteen participants were recruited through stratified purposive sampling according to their medication adherence level. Interviews were analysed by interpretative phenomenological analysis.

RESULTS

Medication adherence behaviour was described on a continuum ranging from non-adherent to adherent. Participants' current adherence level was represented as a result of inner negotiations between a variety of influential factors and the successful application of a range of strategies. The influential factors were: experiences with medication, outcome expectations, knowledge of therapeutic options, the traits 'openness' and 'conscientiousness', belief in medical progress, characteristics of the medication, level of trust in one's physician, and perceived autonomy. Facilitating strategies were: establishing routines, using social support and the deliberate suppression of information about potential adverse events.

CONCLUSION

The experience of and the reasons for medication (non-)adherence from the perspective of people with RA were explored comprehensively. Participants' ongoing negotiations between adherence and non-adherence emerged as a key finding with implications for health service providers.

Non-adherence to disease-modifying antirheumatic drugs is associated with higher disease activity in early arthritis patients in the first year of the disease

Introduction

Non-adherence to disease-modifying antirheumatic drugs (DMARDs) hampers the targets of rheumatoid arthritis (RA) treatment, obtaining low disease activity and decreasing radiological progression. This study investigates if, and to what extent, non-adherence to treatment would lead to a higher 28-joint count disease activity score (DAS28) in the first year after diagnosis.

Methods

Adult patients from an ongoing cohort study on treatment adherence were selected if they fulfilled the EULAR/ACR2010 criteria for RA, and were to start with their first DMARDs. Clinical variables were assessed at baseline and every 3 months. Non-adherence was continuously electronically measured and was defined as the proportion of days with a negative difference between expected and observed openings of the medication container out of the 3-month period before DAS28 measurement. Generalized linear mixed models were used to investigate whether the DAS28 related to non-adherence. Covariates included were age, sex, baseline DAS28, rheumatoid factor positivity, anti-cyclic citrullinated peptide antibodies (ACPA) positivity, anxiety, depression, weeks of treatment, number of DMARDs used, education level, use of subcutaneous methotrexate and biological use.

Results

One hundred and twenty patients met the inclusion criteria for RA. During the study period 17 patients became lost to follow-up. There was a decline in adherence over time for all DMARDs except for prednisone. Non-adherence is a predictor of disease activity in the first 6 months of therapy, adjusted for weeks of treatment, baseline DAS28, and baseline anxiety.

Conclusions

Non-adherence relates to disease activity. Therefore, interventions towards enhancing adherence can improve disease outcome.
