Perceived need to take medication is associated with medication non-adherence in patients with rheumatoid arthritis

Measuring Patient Preferences to Inform Clinical Trial Design: An Example in Rheumatoid Arthritis

BACKGROUND

Allogeneic bone marrow transplantation (BMT) may be a curative treatment for patients with rheumatoid arthritis (RA), but it has serious risks, including death. It is uncertain whether patients would accept the risks and benefits of BMT and participate in clinical trials. We conducted a discrete choice experiment (DCE) to quantify risk tolerance and benefit-risk trade-offs to inform the design of a clinical trial for BMT.

METHODS

We conducted a DCE with three attributes (three levels each): chance of stopping disease progression (50-90%), increased chance of death in year after transplant (3-15%), and chance of chronic graft-versus-host disease (cGVHD) (3-15%). An orthogonal main effects design of nine binary choice tasks were presented for two scenarios: one considering their current situation and a second scenario where the patient has failed seven anti-rheumatic drugs. Participants were recruited from the Rheum4U inflammatory arthritis registry. Choice data were analyzed using a logit model accounting for multiple responses per participant.

RESULTS

Sixty patients participated. Most (82%) had severe disease, and the median number of anti-rheumatic drugs previously taken was 6 (range 0-18). As expected, an increased chance of stopping disease progression increases the probability of choosing BMT, while increased chance of both risks decreases the probability. Patients were willing to accept a 3% increase in risk of death or 6% increase in chance of chronic GVHD for a 10% increase in the chance of stopping disease progression. For the most clinically likely BMT risk-benefit profiles, and the likely initial target population of patients who have failed multiple biologics, between 72% and 91% of patients would choose BMT.

CONCLUSIONS

Patients with RA are willing to accept substantial risks for a chance to stop disease progression with BMT, suggesting that a pilot trial of BMT for RA could successfully recruit patients. Preference studies have an important role in informing patient-centered clinical trial planning and design.

Identifying the Relative Importance of Factors Influencing Medication Compliance in General Patients Using Regularized Logistic Regression and LightGBM: Web-Based Survey Analysis

BACKGROUND

Medication compliance, which refers to the extent to which patients correctly adhere to prescribed regimens, is influenced by various psychological, behavioral, and demographic factors. When analyzing these factors, challenges such as multicollinearity and variable selection often arise, complicating the interpretation of results. To address the issue of multicollinearity and better analyze the importance of each factor, machine learning methods are considered to be useful.

OBJECTIVE

This study aimed to identify key factors influencing medication compliance by applying regularized logistic regression and LightGBM.

METHODS

A questionnaire survey was conducted among 638 adult patients in Japan who had been continuously taking medications for at least 3 months. The survey collected data on demographics, medication habits, psychological adherence factors, and compliance. Logistic regression with regularization was used to handle multicollinearity, while LightGBM was used to calculate feature importance.

RESULTS

The regularized logistic regression model identified significant predictors, including "using the drug at approximately the same time each day" (coefficient 0.479; P=.02), "taking meals at approximately the same time each day" (coefficient 0.407; P=.02), and "I would like to have my medication reduced" (coefficient -0.410; P=.01). The top 5 variables with the highest feature importance scores in the LightGBM results were "Age" (feature importance 179.1), "Using the drug at approximately the same time each day" (feature importance 148.4), "Taking meals at approximately the same time each day" (feature importance 109.0), "I would like to have my medication reduced" (feature importance 77.48), and "I think I want to take my medicine" (feature importance 70.85). Additionally, the feature importance scores for the groups of medication adherence-related factors were 77.92 for lifestyle-related items, 52.04 for awareness of medication, 20.30 for relationships with health care professionals, and 5.05 for others.

CONCLUSIONS

The most significant factors for medication compliance were the consistency of medication and meal timing (mean of feature importance), followed by the number of medications and patient attitudes toward their treatment. This study is the first to use a machine learning model to calculate and compare the relative importance of factors affecting medication adherence. Our findings demonstrate that, in terms of relative importance, lifestyle habits are the most significant contributors to medication compliance among the general patient population. The findings suggest that regularization and machine learning methods, such as LightGBM, are useful for better understanding the numerous adherence factors affected by multicollinearity.

Adherence, Fears, and Beliefs about Biologic Drugs in Rheumatoid Arthritis Patients: A North African Pilot Study

Purpose

To investigate the impact of beliefs in adherence to biologic drugs among patients with rheumatoid arthritis (RA).

Methods

This was a cross-sectional study, including RA patients who were on biologic disease-modifying antirheumatic drugs (bDMARDs). Therapeutic adherence was evaluated arbitrarily using a self-reported method by asking them the following question: "Do you regul arly take your biologic drug as prescribed by your doctor?". The Beliefs about Medicines Questionnaire (BMQ) was used to evaluate medication beliefs [general overuse, general harm, specific necessity, specific concerns].

Results

Seventy-five RA patients were included (80.0% females, 33.3% illiterate, and 68.0% unemployed, mean age: 57±9 years, mean disease activity score: 3.94±1.32). Adherence to the current biologic drug was reported by 71 patients (94.7%). The means ± standard deviation scores for general overuse, general harm, specific necessity, and specific concerns were 14.0±2.4, 10.8±4.4, 20.6±5.7, and 10.3±3.3, respectively. Compared to the adherent group (n=71), the non-adherent group (n=4) had a lower specific necessity score (21.0±5.4 vs. 13.5±7.5, respectively, p=0.009), a higher specific concern score (10.1±3.13 vs. 15.0±2.8, respectively, p=0.036), and similar scores for general overuse and general harm (10.0±2.3 vs. 9.5±1.9, p=0600; 13.3±4.4 vs. 11.5±4.1, p=0.400, respectively). In logistic regression, specific necessity and specific concerns scores were significantly associated with adherence (Odds-ratio (OR)= 0.855, 95% confidence interval (CI) [0.726-1.006], and 1.438, 95% CI [1.004-1.980], respectively).

Conclusion

Our study showed that RA patients have strong beliefs about the necessity to take biologic drugs which significantly influence the adherent behaviour therapy.

The correlation between 4 adherence measurements methods in patients with rheumatoid arthritis using methotrexate

AIMS

Methotrexate (MTX) is the cornerstone in the treatment of rheumatoid arthritis (RA) patients. However, adherence to MTX therapy is not optimal, and instruments to assess medication nonadherence are warranted. To date there is no consensus on the best method to determine adherence to MTX. The aim of this study was to assess the correlation between adherence assessed with a Medication Event Monitoring System (MEMS) vs. pill count, MTX-polyglutamate (PG) concentration and Compliance Questionnaire-Rheumatology (CQR) in patients with established RA. Second, the correlations between these methods and the Disease Activity Scores of 28 joints (DAS28) were examined.

METHODS

Adult RA patients currently treated with MTX were included. Multivariable linear and logistic regression were used, with adherence assessed with MEMS as dependent variable vs. pill count, MTX-PG concentrations, CQR as independent variables and DAS28 vs. each of the 4 adherence measurements. Covariates were included, such as comedication, age and use of corticosteroids.

RESULTS

In total, 190 consecutive RA patients were included. Pill count was correlated with adherence assessed with MEMS (linear regression, β = 0.588, 95% confidence interval = 0.255-0.921, P < .001), whereas CQR and MTX-PGs were not. Logistic regression confirmed the correlation between dichotomized adherence and pill count only (β = 4.47, 95% confidence interval = 1.31-7.64, P =  .006). No other correlations were found, either for all adherence outcomes or DAS28.

CONCLUSION

Measuring adherence with MEMS is correlated with pill count, whereas other methods were not correlated with MEMS or with DAS28. Pill count can be used to estimate adherence to MTX therapy, in case MEMS is not achievable.

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.

Perceptions of conflicting information about long-term medications: a qualitative in-depth interview study of patients with chronic diseases in the Swiss ambulatory care system

OBJECTIVE

Patients with multiple long-term conditions visit various healthcare professionals and are exposed to medication information from various sources causing an increased risk of patients perceiving contradictory medication information. The aims of this study are to: (1) characterise conflicting medication information perceived by patients with long-term conditions, (2) better understand the related impact on patients' medication self-management and healthcare system navigation and (3) explore ways in which such events could be prevented.

DESIGN

This study was conducted through qualitative semistructured interviews. Data were analysed using thematic analysis.

SETTING

Community pharmacies and medical centres in Geneva, Switzerland.

PARTICIPANTS

This study included outpatients from April 2019 to February 2020. Patients were included after participating in a quantitative survey of perceived conflicting information about medications for long-term diseases.

METHODS

Semistructured audiotaped interviews of 20 to 60 min following a pre-established interview guide to explore participants' perceptions of conflicting information. Interviews were transcribed verbatim, and a thematic analysis was conducted with inductive and deductive coding using MAXQDA (2018, Release 18.2.3).

RESULTS

Twenty-two patients were interviewed, until data saturation, mentioning indication or need for a medication as the main topic of conflicting information between two healthcare professionals. Perceived conflicting information often resulted from insufficient information provided and poor communication leading to confusion, doubts and medication non-adherence. Patients expected more information and more interprofessional communication on their medications. As a result of conflicting information, most participants learnt or were learning to take an active role and become partners of the healthcare providers.

CONCLUSION

The need to strengthen and improve communication and interprofessional collaborative practice among healthcare professionals and with the patient is emerging to increase the quality and consistency of information about medications, and consequently, to ensure better use and experience of medications.

Medication beliefs, adherence, and outcomes in people with asthma: The importance of treatment beliefs in understanding inhaled corticosteroid nonadherence-a retrospective analysis of a real-world data set

Background

Poor adherence to inhaled corticosteroids (ICSs) increases asthma morbidity and mortality and is influenced by patients' treatment beliefs. This study maps patients' beliefs about ICSs across 6 countries examining variations in beliefs, and their relationship with adherence and outcomes.

Objective

We sought to explore the relationship between patient treatment beliefs, and adherence and outcomes in asthma across 6 countries.

Methods

Patients 18 years or older with asthma, receiving ICS alone or in combination with a long-acting β2-agonist, were included from a point-in-time paper survey of patients with asthma in Europe and the United States. Clinical characteristics, such as adherence and asthma control, were collected by self- and physician-report. Patients completed the Beliefs about Medicines Questionnaire, adapted for ICSs. Relationships between patient treatment beliefs, adherence, and outcomes were examined using regression analyses.

Results

Data from 1312 patients were analyzed. Patients were from Germany (24%), the United States (21%), France (21%), Spain (16%), Italy (10%), and the United Kingdom (9%). Most had physician-reported mild-intermittent asthma (87%), and mean age was 40 ± 15.5 years. There was considerable variation in necessity beliefs between countries, with respondents in Italy having more doubts about treatment necessity and respondents in Spain showing higher concerns. Patients with doubts about ICS necessity and high concerns had lower self-reported (necessity: χ2(2) = 34.31, P < .001; concerns: χ2(2) = 20.98, P < .001) and physician-reported adherence (necessity: χ2(2) = 11.70, P = .003; concerns: χ2(2) = 34.45, P < .001). Patients with high necessity beliefs (F(2, 483) = 3.33; P = .037) and high concerns (F(2,483) = 23.46; P < .001) reported poorer control. Physician estimates of adherence did not correlate well with patient self-report (ρ = 0.178, P < .001).

Conclusions

ICS necessity beliefs and concerns were associated with adherence and asthma control. This has implications for the design of adherence interventions.

Primary nonadherence to drugs prescribed by general practitioners: A Dutch database study

AIM

Primary nonadherence (PNA) is defined as not filling the first prescription for a drug treatment. PNA can lead not only to poor patient outcomes but also to exposure misclassification in written prescription databases. This study aims to estimate PNA in primary care in the Netherlands and to investigate associated factors.

METHODS

Patients from the Nivel Primary Care Database (Nivel-PCD) who received a new prescription (>1 year not prescribed) from a general practitioner in 2012 were linked to pharmacy dispensing information of consenting pharmacies based on sex, year of birth, four-digit postal code and at least 50% matching Anatomical Therapeutic Classification codes. PNA was defined as not having a prescription dispensed within 30 days from the prescribing date. PNA was assessed overall and per drug class. The associations between PNA and several patient- and prescription-related characteristics were assessed using mixed-effects logistic regression models.

RESULTS

After matching 86 361 of 396 251 subjects (21.8%) in the Nivel-PCD records to the pharmacy records, this study included 65 877 subjects who received 181 939 new drug prescriptions. Overall, PNA was 11.5%. PNA was lowest for thyroid hormones (5.5%) and highest for proton pump inhibitors (12.8%). Several factors were associated with PNA, such as having comorbidities (odds ratio [OR] 1.46, 95% confidence interval [CI] 1.37-1.56 for >3 active diagnoses, compared to no active diagnoses) or reimbursement status (OR 2.78, 95% CI 2.65-2.92 for not reimbursed drugs compared to fully reimbursed drugs).

CONCLUSIONS

A total of 11.5% of newly prescribed drugs were not dispensed. This can lead to overestimation of the actual drug exposure status when using written prescription databases.

Clinical and psychological characteristics associated with negative beliefs and concerns about treatment necessity in rheumatic diseases

Identifying factors that influence problematic beliefs and behaviors related to pharmacotherapy may be useful for clinicians to improve the patients' adherence. The study aims to assess patients' beliefs about the necessity and concerns regarding pharmacotherapy in rheumatic diseases and attitude styles, and to investigate the association between clinical factors and negative beliefs about medication. A sample of 712 patients affected by Rheumatoid Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis was enrolled. They were assessed using the Beliefs about Medicines Questionnaires-Specific (BMQ), the Simplified Disease Activity Index (SDAI), the Visual Analogue Scale for pain (VAS), the Chalder Fatigue Scale (CFQ) and the Health Assessment Questionnaire-Disability Index (HAQ-DI). The balance between benefits and costs in the BMQ-Specific was positive in the 79.4% of patients, negative in the 12.1% and equal in the 8.6%. SDAI, taking more than 5 medications, taking anti interleukin 6 (Anti-IL6) or biological disease-modifying antirheumatic drugs (bDMARDs), or targeted synthetic disease-modifying antirheumatic drugs (tsDMARDs), pain, and fatigue were significantly associated to higher Concerns. Having a longer disease duration was significantly associated with a higher Necessity, together with the current pharmacological treatments and the disability. The multivariate regression models estimated that higher pain and fatigue were associated to higher Concerns (p < 0.001), while a longer disease duration (p < 0.001) and all pharmacological treatments for a rheumatologic disease (p = 0.001) were associated to higher Necessity levels. A high length of disease, a low level of remission, a high number of total medications, the prescription of an Anti-IL6/bDMARDs/tsDMARDs drug, a high level of pain, fatigue and disability identified patients potentially less adherent to pharmacotherapy to be carefully looked after by clinicians.

Neuroticism and Conscientiousness Moderate the Effect of Oral Medication Beliefs on Adherence of People with Mental Illness during the Pandemic

Background. After the declaration of the pandemic status in several countries, the continuity of face-to-face visits in psychiatric facilities has been delayed or even interrupted to reduce viral spread. Little is known about the personality factors associated with medication beliefs and adherence amongst individuals with mental illness during the COVID-19 pandemic. This brief report describes a preliminary naturalistic longitudinal study that explored whether the Big Five personality traits prospectively moderate the effects of medication beliefs on changes in adherence during the pandemic for a group of outpatients with psychosis or bipolar disorder. Methods. Thirteen outpatients undergoing routine face-to-face follow-up assessments during the pandemic were included (41 observations overall) and completed the Revised Italian Version of the Ten-Item Personality Inventory, the Beliefs about Medicines Questionnaire, the Morisky Medication Adherence Scale—8-item and the Beck Depression Inventory—II. Results. Participants had stronger concerns about their psychiatric medications rather than beliefs about their necessity, and adherence to medications was generally low. Participants who had more necessity beliefs than concerns had better adherence to medications. People scoring higher in Conscientiousness and Neuroticism traits and more concerned about the medication side effects had poorer adherence. Conclusions. These preliminary data suggest the importance of a careful assessment of the adherence to medications amongst people with psychosis/bipolar disorder during the pandemic. Interventions aimed to improve adherence might focus on patients’ medication beliefs and their Conscientiousness and Neuroticism personality traits.

Effectiveness of electronic drug monitoring feedback to increase adherence in patients with RA initiating a biological DMARD: a randomised clinical trial

Objective

Medication non-adherence in rheumatoid arthritis (RA) is associated with disease flares, increased disability and increased costs. This study assessed the effectiveness of electronic monitoring feedback (EMF) on medication adherence in patients with RA starting with or switching to a new biological disease-modifying antirheumatic drug (bDMARD).

Methods

In this randomised controlled trial, bDMARD starters were assigned to the intervention or control group and followed for 1 year. The intervention group received a needle container with a Medication Event Monitoring System (MEMS) cap registering patient’s adherence to injections. Scores were calculated every 3 months with MEMS and motivational interviewing feedback was given. The control group received usual care. Effectiveness of EMF on adherence was measured with the medication possession ratio (MPR).

Results

104 consecutive intervention patients were included and 102 controls. MPR was 0.95 (SD: 0.10) and 0.90 (0.16) after 12 months (B: 0.036, 95% CI: 0.001 to 0.007, p=0.045). bDMARD-naive patients receiving EMF achieved low disease activity (LDA) sooner compared with the control group, adjusted for baseline DAS (HR: 1.68, 95% CI: 1.00 to 2.81, p=0.050). Side effects and DAS28 were similar.

Conclusion

EMF increased adherence for patients with RA starting with or switching to a bDMARD. Especially bDMARD-naive patients achieved LDA sooner compared with the control group, which holds promise for the future.

Measuring the impact of an educational intervention in rheumatoid arthritis: An open-label, randomized trial

Objectives

This study aims to determine whether patients with active rheumatoid arthritis (RA), either starting on or changing biological or targeted synthetic disease-modifying antirheumatic drugs (DMARDs), demonstrate better self-management safety skills three months after receiving a multidisciplinary educational intervention compared to patients receiving usual care.

Patients and methods

Between October 2015 and October 2018 , this open-label, randomized-controlled trial included a total of 107 RA patients (27 males, 80 females; mean age: 60.2±10.4 years; range, 54 to 71 years) who were on treatment or in whom treatment was changed with a biological or targeted synthetic DMARD. The patients were randomized into two groups: Group 1 (n=57) received additional intervention with educational DVD and one teleconference session and Group 2 (n=55) received usual care and were offered the intervention at three months. All patients underwent a final visit at six months. At each visit, the patients completed the BioSecure questionnaire measuring the self-care safety skills, a behavioral intention questionnaire, and the Beliefs about Medicines Questionnaire (BMQ).

Results

No significant difference was observed in the Biosecure score at three months between the two groups (p=0.08). After pooling the first three-month data in Group 1 and the last three-month data in Group 2, the mean score of the BioSecure questionnaire increased to 7.10±0.92 in the group receiving educational intervention (p<0.0001). This increase was maintained at six months in Group 2 (p=0.88). The rate of appropriate behavioral intention increased over time (76% at baseline and 85% at six months for both groups). There was no significant change in the BMQ (p=0.44 to 0.84).

Conclusion

The development of an educational DVD followed by a teleconference seem to improve self-care safety skills of the patients in practical situations.

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.

Medication adherence among Nigerian patients with rheumatoid arthritis: a two instruments survey

Objectives

Medication adherence is still a significant problem in chronic diseases management and rheumatoid arthritis (RA) is not an exception. There is very little information regarding the level and influencing factors of medication adherence among Nigerian patients with RA. This study evaluated the level and determinants of medication adherence among patients with RA in a Nigerian referral hospital.

Methods

Using a questionnaire based cross sectional survey, 169 patients with RA were evaluated for their medication adherence using two validated instruments namely; five-item Medication Adherence Report Scale and five-item Compliance Questionnaire for Rheumatology. The two instruments were subjected to descriptive (mean and frequencies) and mean difference (chi-square, t-test, Pearson correlation) analysis, and their reliability (Cronbach alpha) in a Nigerian setting was also established.

Key findings

The level of non-adherence reported in this study was high and ranged from 48.5% for the CQR to 63.9% for the Medication Adherence Report Scale questionnaires respectively. Being of a male gender, of an older age, the higher number of pills taken, better education and the duration of the disease all significantly contributed to higher adherence measures among these RA patients (P &lt;0.05 for all). Both questionnaires used were correlated and reliable for use among patients with rheumatoid arthritis in Nigeria.

Conclusion

Findings from this study show that non adherence to medications among RA patients were high and factors such age, gender, education, pill burden could have been responsible.

Beliefs and attitudes toward endocrine therapy in patients with hormone receptor-positive breast cancer

Patients' beliefs about medications are important predictors of medication adherence; however, the relationship between patient beliefs and adjuvant endocrine therapy (AET) adherence in patients with breast cancer remains unclear. In this study, we aimed to determine the association between patient beliefs and adherence to AET. Self-reported questionnaires covering necessity beliefs (NB), concerns beliefs (CB), and adherence were completed by 210 Korean patients with breast cancer. The rate of nonadherence was determined by calculating necessity-concern (N-C) differentials and attitudinal subgroup analysis. Multivariate logistic regression analysis was performed to determine the independent impact of patient beliefs on nonadherence. Nonadherence (Morisky Medication Adherence Scale < 8) was reported in 74.3% (n = 156) of patients and predicted by a negative balance regarding AET [odds ratio (OR) = 0.89; 95% confidence interval (CI): 0.83-0.96] and strong concerns about AET such as those in the Ambivalent (OR = 5.41; 95% CI: 1.84-15.92) and Skeptical (OR = 3.48, 95% CI: 1.14-10.65) subgroups. Patient beliefs are significantly associated with adherence to AET in Korean patients with breast cancer. NB, CB, and N-C differentials may be useful intervention targets to improve medication adherence.

Pop a pill or give myself a shot? Patient perspectives of disease-modifying anti-rheumatic drug choice for rheumatoid arthritis

OBJECTIVE

To assess how patients with rheumatoid arthritis (RA) decide whether to add oral disease-modifying anti-rheumatic drugs (DMARDs) versus injectable biologic DMARDs when methotrexate response is inadequate.

METHODS

Using nominal group technique (NGT), RA patients answered the question "What sort of things are important to you when you make a decision between adding pills versus injectable medications to treat rheumatoid arthritis when methotrexate fails to control RA disease activity?" Patients nominated, discussed, and voted for the responses.

RESULTS

Forty-seven RA patients participated: Birmingham (n=6 NG; 21 patients) and New York City (n=4 NG; 26 patients). They were predominantly female (85%), 70% white, with a mean age of 64.5 years and 58% had>10-year RA duration. Present/past DMARDs included methotrexate only in 6%, other traditional DMARDs in 15%, glucocorticoids in combination with traditional DMARDs in 11%, and biologics and/or Jak-kinase inhibitors in 68% of participants. Voted domains in order were: (1) efficacy/effectiveness and the onset/mode of action (78/282 votes); (2) side effects/fear of side effects (84/282 votes); (3) cost including out of pocket, co-payments and patient responsibility (54/282 votes); (4) convenience/frequency of use (27/282 votes); (5) doctor's opinion (20/282 votes); (6) other drugs/comorbidity/other patient's experience/effects on other people (3/282 votes); (7) fear of needles (8/282 votes); and (8) newness of the medication (8/282 votes).

CONCLUSIONS

We identified the patient perspective regarding the choice between adding oral versus injectable DMARD once methotrexate failed to control RA disease activity. This knowledge can help in shared decision-making for DMARD choice in RA treatment.

Are Health Care Professionals' Implicit and Explicit Attitudes Toward Conventional Disease-Modifying Antirheumatic Drugs Associated With Those of Their Patients?

OBJECTIVE

It is generally unknown how the attitudes and beliefs of health care professionals (HCPs) might affect the attitudes, beliefs, and medication-taking behavior of patients with rheumatoid arthritis (RA). This study aims 1) to examine the attitudes, health-related associations (both implicit and explicit), and beliefs of HCPs about conventional disease-modifying antirheumatic drugs, and 2) to assess whether these attitudes, health-related associations, and beliefs of HCPs are associated with those of their patients, with their patients' medication-taking behavior, and disease activity.

METHODS

HCPs were recruited from 2 centers that specialized in rheumatology across The Netherlands, and patient recruitment followed. In this observational study, implicit outcomes were measured with single-category implicit association tests, whereas explicit outcomes were measured with a bipolar evaluative adjective scale and the Beliefs About Medicines Questionnaire-Specific. Spearman's rank correlations were used to describe correlations between implicit and explicit measures of the attitudes of HCPs. Multilevel, mixed-effects linear models were used to examine the association of HCP-related characteristics, including the implicit and explicit outcomes of HCPs, with those of their patients, their medication-taking behaviors, and disease activity.

RESULTS

Of the 1,659 initially invited patients, 254 patients with RA (mean age 62.8 years, mean disease duration 11.8 years, and 68.1% of the patients were female) who were treated by 26 different HCPs agreed to participate in this study. The characteristics, attitudes, health-related associations, and beliefs about medicines of HCPs were not significantly associated with those of their patients, nor with their medication-taking behaviors or disease activity scores.

CONCLUSION

This study demonstrated that the attitudes, health-related associations (as measured both implicitly and explicitly), and beliefs of HCPs were not significantly associated with the attitudes, beliefs, medication-taking behavior, and disease activity of patients with RA.

Implicit and explicit attitudes towards disease-modifying antirheumatic drugs as possible target for improving medication adherence

OBJECTIVE

This study aims to explore the contribution of implicit attitudes and associations towards conventional disease-modifying antirheumatic drugs (cDMARDs), alongside explicit measures, on medication-taking behaviour and clinical outcomes in adult patients with rheumatoid arthritis (RA).

METHODS

In this observational study, implicit attitudes (positive-negative) and health-related associations (health-sickness) were measured with Single Category Implicit Association Tests, whereas explicit outcomes were measured with a bipolar evaluative adjective scale and the Beliefs about Medicines Questionnaire Specific. The primary outcome of this study was medication-taking behaviour subjectively measured by self-report (i.e. validated Compliance Questionnaire on Rheumatology) and objectively measured with electronic drug monitors over a 3 month period. Spearman rank correlations were used to describe correlations between implicit and explicit outcomes. Nested linear regression models were used to assess the additional value of implicit measures over explicit measures and patient-, clinical-, and treatment-related characteristics.

RESULTS

Of the 1659 initially-invited patients, 254 patients with RA agreed to participate in this study. Implicit attitudes correlated significantly with necessity-concerns differential (NCD) scores (ρ = 0.13, P = 0.05) and disease activity scores (ρ = -0.17, P = 0.04), whereas implicit health-related associations correlated significantly with mean scores for explicitly reported health-related associations (ρ = 0.18, P = 0.004). Significant differences in age, number of DMARDs, biologic DMARD use, NCD-scores, and self-reported correct dosing were found between the four attitudinal profiles. Nested linear regression models revealed no additional value of implicit measures in explaining self-reported medication-taking behaviour and clinical outcomes, over and above all other variables.

CONCLUSION

Implicit attitudes and associations had no additional value in explaining medication-taking behaviour and clinical outcomes over and above often used explicitly measured characteristics, attitudes and outcomes in the studied population. Only age and NCD scores contributed significantly when the dependent variable was correct dosing measured with self-report.

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.

Medication Adherence and Coping Strategies in Patients with Rheumatoid Arthritis: A Cross-Sectional Study

Objectives

The aim of this study was to determine if strategies for coping with illnesses, demographic factors, and clinical factors were associated with medication adherence among patients with rheumatoid arthritis (RA).

Methods

This cross-sectional study was conducted at a Viennese rheumatology outpatient clinic on RA patients. Medication adherence was assessed using the Medication Adherence Report Scale. Strategies for coping with illness were assessed using the Freiburg Questionnaire for Coping with Illness.

Results

Half (N=63, 52.5%) of the 120 patients included in the study were considered completely medication adherent. Female sex (odds ratio [OR]: 4.57, 95% confidence interval [CI]: 1.14 – 18.42), older age (54-65 yr vs. <45 yr OR: 9.2, CI:2.0-40.70; >65 yr vs. <45 yr OR 6.93, CI:1,17 – 40.87), middle average income (middle average income vs. lowest income class OR= 0.06, CI= 0.01-0.43), and shorter disease duration (5-10 yr vs. >10 yr OR= 3.53, CI= 1.04-11.95; 1-4 yr vs. >10 yr OR=3.71, CI= 1.02-13.52) were associated with higher medication adherence. Levels of active coping (15.57 vs. 13.47, p=0.01) or diversion and self-encouragement (16.10 vs. 14.37, p=0.04) were significantly higher among adherent as opposed to less adherent participants. However, in multivariate regression models, coping strategies were not significantly associated with adherence.

Conclusions

Age, sex, monthly net income, and disease duration were found to be associated with an increased risk for medication nonadherence among patients with RA. Coping strategies such as active coping, diversion, and self-encouragement were associated with adherence in univariate models, but not when adjusted for demographic and clinical factors.

Adherence and health literacy as related to outcome of patients treated for rheumatoid arthritis : Analyses of a large-scale observational study

BACKGROUND

Disabilities in daily living and quality of life are key endpoints for evaluating the treatment outcome for rheumatoid arthritis (RA). Factors possibly contributing to good outcome are adherence and health literacy.

METHODS

The survey included a representative nationwide sample of German rheumatologists and their patients with RA. The physician questionnaire included the disease activity score (DAS28) and medical prescriptions. The patient questionnaire included fatigue (EORTC QLQ-FA13), health assessment questionnaire (HAQ), quality of life (SF-12), health literacy (HELP), and patients' listings of their medications. Adherence was operationalized as follows: patient-reported (CQR5), behavioral (concordance between physicians' and patients' listings of medications), physician-assessed, and a combined measure of physician rating (1 = very adherent, 0 = less adherent) and the match between physicians' prescriptions and patients' accounts of their medications (1 = perfect match, 0 = no perfect match) that yielded three categories of adherence: high, medium, and low. Simple and multiple linear regressions (controlling for age, sex, smoking, drinking alcohol, and sport) were calculated using adherence and health literacy as predictor variables, and disease activity and patient-reported outcomes as dependent variables.

RESULTS

708 pairs of patient and physician questionnaires were analyzed. The mean patient age (73% women) was 60 years (SD = 12). Multiple regression analyses showed that high adherence was significantly associated with 5/7 outcome variables and health literacy with 7/7 outcome variables.

CONCLUSION

Adherence and health literacy had weak but consistent effects on most outcomes. Thus, enhancing adherence and understanding of medical information could improve outcome, which should be investigated in future interventional studies.

Predicting adherence to therapy in rheumatoid arthritis, psoriatic arthritis or ankylosing spondylitis: a large cross-sectional study

Objective

This analysis explored the association of treatment adherence with beliefs about medication, patient demographic and disease characteristics and medication types in rheumatoid arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS) to develop adherence prediction models.

Methods

The population was a subset from ALIGN, a multicountry, cross-sectional, self-administered survey study in adult patients (n=7328) with six immune-mediated inflammatory diseases who were routinely receiving systemic therapy. Instruments included Beliefs about Medicines Questionnaire (BMQ) and 4-item Morisky Medication Adherence Scale (MMAS-4^©), which was used to define adherence.

Results

A total of 3390 rheumatological patients were analysed (RA, n=1943; PsA, n=635; AS, n=812). Based on the strongest significant associations, the adherence prediction models included type of treatment, age, race (RA and AS) or disease duration (PsA) and medication beliefs (RA and PsA, BMQ-General Harm score; AS, BMQ-Specific Concerns score). The models had cross-validated areas under the receiver operating characteristic curve of 0.637 (RA), 0.641 (PsA) and 0.724 (AS). Predicted probabilities of full adherence (MMAS-4^©=4) ranged from 5% to 96%. Adherence was highest for tumour necrosis factor inhibitors versus other treatments, older patients and those with low treatment harm beliefs or concerns. Adherence was higher in white patients with RA and AS and in patients with PsA with duration of disease <9 years.

Conclusions

For the first time, simple medication adherence prediction models for patients with RA, PsA and AS are available, which may help identify patients at high risk of non-adherence to systemic therapies.

Preferences of patients with rheumatoid arthritis regarding disease-modifying antirheumatic drugs: a discrete choice experiment

BACKGROUND

Although patients have different treatment preferences, these individual preferences could often be grouped in subgroups with shared preferences. Knowledge of these subgroups as well as factors associated with subgroup membership supports health care professionals in the understanding of what matters to patients in clinical decision-making.

OBJECTIVES

To identify subgroups of patients with rheumatoid arthritis (RA) based on their shared preferences toward disease-modifying antirheumatic drugs (DMARDs), and to identify factors associated with subgroup membership.

METHODS

A discrete choice experiment to determine DMARD preferences of adult patients with RA was designed based on a literature review, expert recommendations, and focus groups. In this multicenter study, patients were asked to state their preferred choice between two different hypothetical treatment options, described by seven DMARD characteristics with three levels within each characteristic. Latent class analyses and multinomial logistic regressions were used to identify subgroups and the characteristics (patient characteristics, disease-related variables, and beliefs about medicines) associated with subgroup membership.

RESULTS

Among 325 participating patients with RA, three subgroups were identified: an administration-driven subgroup (45.6%), a benefit-driven subgroup (29.7%), and a balanced subgroup (24.7%). Patients who were currently using biologic DMARDs were significantly more likely to belong to the balanced subgroup than the administration-driven subgroup (relative risk ratio (RRR): 0.50, 95% CI: 0.28-0.89). Highly educated patients were significantly more likely to belong to the benefit-driven subgroup than the balanced subgroup (RRR: 11.4, 95% CI: 0.97-133.6). Patients' medication-related concerns did not contribute significantly to subgroup membership, whereas a near-significant association was found between patients' beliefs about medication necessity and their membership of the benefit-driven subgroup (RRR: 1.12, 95% CI: 1.00-1.23).

CONCLUSION

Three subgroups with shared preferences were identified. Only biologic DMARD use and educational level were associated with subgroup membership. Integrating patient's medication preferences in pharmacotherapy decisions may improve the quality of decisions and possibly 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.

Treatment adherence in systemic sclerosis: A cross-sectional study

BACKGROUND

Treatment adherence is an important medical and pharmaco-economical phenomenon, influenced by multiple variables. Treatment adherence in systemic sclerosis (SSc) has been poorly studied.

OBJECTIVE

The aim of the present study was to assess treatment adherence in SSc patients and to identify factors associated with good and poor adherence.

METHODS

We conducted a monocentric, cross-sectional, observational study. Treatment adherence was evaluated by the Compliance Questionnaire of Rheumatology (CQR). The necessity of treatment and concerns about treatment were investigated using the Beliefs about Medicines Questionnaire-Specific (BMQ-S). The Illness Perception Questionnaire-Revised (IPQ-R) assessed illness perceptions. Disease-related characteristics were collected retrospectively.

RESULTS

A total of 66 patients were enrolled in this study. Of these, 47 (71.2%) had a weighted CQR score of ≤80% ("poor adherence") and 19 (28.8%) had a weighted CQR score of >80% ("good adherence"). No significant relationship between demographic, clinical or psychological factors and overall adherence could be found, except with the IPQ subscale "timeline acute/chronic" (p = 0.042). Our patient population estimated the necessity of their medication high (mean necessity score 20.5), with moderate concern beliefs (mean concern score 15.1). Subjective adherence, as self-reported by patients, was high.

CONCLUSIONS

This study demonstrated low treatment adherence rates in SSc patients. We could not identify demographic, clinical or psychological factors associated with treatment adherence, except with the IPQ subscale "timeline acute/chronic". This suggests a correlation between poor adherence and the belief that the disease will be chronic without improvement over time. Symptom relief was an important motivating factor for taking medication. The treatment necessity was scored higher than treatment concerns, but the necessity beliefs were not associated with adherence.

Open-Label, Non-Mandatory Transitioning From Originator Etanercept to Biosimilar SB4: Six-Month Results From a Controlled Cohort Study

OBJECTIVE

To evaluate the effects of non-mandatory transitioning from the originator biologic drug etanercept (ETN) to its biosimilar, SB4, on drug survival and effectiveness in a controlled cohort study of patients with an inflammatory rheumatic disease.

METHODS

In 2016, 642 patients were asked to transition their treatment from originator ETN to biosimilar SB4 by a structured communication strategy with opt-out option. Patients who consented to switch to SB4 were considered eligible for inclusion in the transition cohort, while patients being treated with originator ETN in 2014 were recruited as the historical cohort. Drug survival was compared between the 2 cohorts using Cox regression analyses, which were adjusted for age, sex, diagnosis, ETN treatment duration, ETN dose interval, conventional synthetic disease-modifying antirheumatic drug usage, and C-reactive protein (CRP) level, with a robust variance estimator applied to account for repeated subjects (i.e., patients who were included in both the transition cohort and the historical cohort). Adjusted differences in the 6-month change in CRP level, Disease Activity Score in 28 joints using CRP level (DAS28-CRP), and Bath Ankylosing Spondylitis Disease Activity Index were also assessed.

RESULTS

Of the 642 ETN-treated patients, 635 (99%) agreed to transition from originator ETN to biosimilar SB4, of whom 625 patients (433 with rheumatoid arthritis, 128 with psoriatic arthritis, and 64 with ankylosing spondylitis) were included in the transition cohort, and 600 ETN-treated patients from 2014 were included in the historical cohort. The crude treatment persistence rate for biosimilar SB4 over 6 months was 90% (95% confidence interval [95% CI] 88-93%), compared to a 6-month treatment persistence rate of 92% (95% CI 90-94%) for originator ETN. Patients in the transition cohort, compared to the historical cohort, had a statistically significantly higher relative risk of treatment discontinuation (adjusted hazard ratio 1.57, 95% CI 1.05-2.36) and showed smaller decreases in the CRP level (adjusted difference 1.8, 95% CI 0.3-3.2) and DAS28-CRP (adjusted difference 0.15, 95% CI 0.05-0.25) over 6 months.

CONCLUSION

Non-mandatory transitioning from originator ETN to biosimilar SB4 using a specifically designed communication strategy resulted in a slightly lower 6-month treatment persistence rate and smaller decreases in disease activity in the transition cohort compared to the historical cohort, but these differences were not considered clinically relevant.

The beliefs of rheumatoid arthritis patients in their subcutaneous biological drug: strengths and areas of concern

Patients' beliefs about their prescribed medication are an important factor influencing intentional non-adherence. This study describes rheumatoid arthritis (RA) patients' beliefs about their subcutaneous (SC) biological medication through the Beliefs about Medicines Questionnaire (BMQ), and potential associations. As part of the ARCO study (Study on Adherence of Rheumatoid arthritis patients to subCutaneous and Oral drugs), patients completed the BMQ specifically for their SC biological medication, encompassing a necessity and a concerns scale. The medication possession ratio (MPR) was calculated to assess adherence to the SC biological medication. The BMQ was completed by 321 patients. Between 71.0 and 89.7% of patients agreed/strongly agreed with necessity scale statements, and only 7.2% had low necessity scores. Between 20.0 and 49.8% of patients agreed/strongly agreed with four of five concern scale statements, and 72.3% agreed/strongly agreed with the concern statement regarding long-term medication effects. The percentage with high concerns was 58.9%, and was higher in patients not satisfied with, or with less fulfillment of, tolerability expectations. Non-adherence percentages were, respectively, 13.8 and 13.0% (p = 0.919) in those with high or low necessity, and 16.0 and 10.6% (p = 0.171) in those with high or low concerns. Most patients were categorized as 'ambivalent' (58.5%; high necessity/high concerns) or 'accepting' (36.1%; high necessity/low concerns) of their SC biological medication. The BMQ identified patients' concerns with their SC biological medication. Because patients' concerns could influence non-adherence to medication and future outcomes, physicians should address this issue in the clinic by informing patients and setting clear expectations.

Effectiveness and cost-effectiveness of duloxetine added to usual care for patients with chronic pain due to hip or knee osteoarthritis: protocol of a pragmatic open-label cluster randomised trial (the DUO trial)

INTRODUCTION

Osteoarthritis (OA) is a highly prevalent painful condition of the musculoskeletal system. The effectiveness of current analgesic options has proven to be limited and improved analgesic treatment is needed. Several randomised placebo-controlled trials have now demonstrated the efficacy of duloxetine, an antidepressant with a centrally acting effect, in the treatment of OA pain. The aim of the current study is to investigate if duloxetine is effective and cost-effective as a third-choice analgesic added to usual care for treating chronic pain compared with usual care alone in general practice.

METHODS AND ANALYSIS

A pragmatic open, cluster randomised trial is conducted. Patients with pain due to hip or knee OA on most days of the past 3 months with insufficient benefit of non-steroidal anti-inflammatory drugs or contraindications or intolerable side effects are included. General practices are randomised to either (1) duloxetine and usual care or (2) usual care only. Primary outcome is pain at 3 months measured on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale. Secondary outcomes at 3 months and 1 year are pain (WOMAC, at 1 year), function (WOMAC), adverse reactions, quality of life and modification of the response to treatment by the presence of centrally sensitised pain (modified PainDETECT). At 1 year, medical and productivity costs will be assessed. Analyses will be performed following the intention-to-treat principle taking the cluster design into account.

ETHICS AND DISSEMINATION

The study is approved by the local Medical Ethics Committee (2015-293). Results will be published in a scientific peer-reviewed journal and will be communicated at conferences.

A systematic review of the barriers affecting medication adherence in patients with rheumatic diseases

Medication adherence is a crucial part in the management of rheumatic diseases, especially with many such patients requiring long-term medications. In this paper, we aim to systematically review the literature for the factors associated with medication adherence in the rheumatic patient population. We carried out a systematic literature search using PubMed^®, PsychInfo^® and Embase ^® with relevant keywords and employed the PRISMA^® criteria. We included English peer-reviewed articles that studied the factors affecting medication adherence in patients with rheumatic diseases, which were assessed by two independent reviewers. Hand searches were conducted and relevant factors were extracted and classified using the World Health Organization (WHO)'s five dimensions of medication adherence. A simple diagram was drawn to summarise the factors extracted. 1977 articles were identified and reviewed and 90 articles were found to be relevant. A total of 17 factors and 38 sub-factors were identified and categorized based on the WHO's five dimensions of medication adherence. A hand model for medication adherence was developed to succinctly summarise these dimension to remind clinicians the importance of medication adherence in daily practice. We conducted a systematic review on the various factors including patient, therapy, condition, health system and socioeconomic-related factors that affected medication adherence in rheumatic patients. We found 17 factors and 38 sub-factors that affected medication adherence in this population. This systematic review can facilitate future focused research in unexplored dimensions.

Functional disability associated with disease and quality-of-life parameters in Chinese patients with rheumatoid arthritis

Background

As an important outcome measure among rheumatoid arthritis (RA) patients, functional disability may contribute to unemployment, loss of work productivity, and impaired quality of life. However, little is known about the risk factors of functional disability in Chinese RA patients. This study aimed (1) to examine the prevalence of functional disability in Chinese RA patients; (2) to explore factors associated with the health assessment questionnaire-disability index (HAQ-DI).

Methods

A total of 101 RA patients in this cross-sectional study underwent standardized laboratory examinations and responded to the questionnaire for demographic data, the HAQ-DI for functional disability, the Compliance Questionnaire on Rheumatology (CQR) for medication adherence, the Hospital Anxiety and Depression Scale (HADS) for psychological status, and the Short Form 36 health survey (SF-36) for quality of life. Pain, grip/pinch strength, disease activity, and large joint mobility were recorded. Independent samples t-tests, chi-square analyses, and logistic regression modeling were used to analyze the data.

Results

The mean ± SD age of RA patients was 54.9 ± 11.9 years. Approximately 15.8% RA patients in mainland China experience functional disability (defined as a HAQ-DI score ≥ 1). Long disease duration, pain, high disease activity, a larger number of tender and swollen joints, high C-reactive protein (CRP) level, decreased grip strength, and limitation of shoulder, elbow, wrist, knee, and ankle motion were associated with the HAQ-DI. Participants with functional disability tended to have more severe depressive symptoms and a lower quality of life compared with individuals without functional disability. Stepwise logistic regression analyses found that limitation of wrist extension (P = 0.001) and lower body pain (BP) score (P = 0.001) explained higher HAQ-DI score.

Conclusions

The present study reported that functional disability was common in Chinese RA patients. A low quality of life and limitation of joint mobility had great impacts on functional disability in Chinese RA patients. Targeted and culturally sensitive interventions should be strengthened to delay the onset of disabilities of this population.

Patients' conceptions of their own influence on good treatment response to biological therapy in chronic inflammatory arthritis

BACKGROUND

Biological therapies are common in the treatment of patients with chronic inflammatory arthritis (CIA). However, despite the fact that many patients respond well to their biological therapies, there are still a number of nonresponders. In order to design the best care for patients, it is important to understand how they conceive their own role in their treatment response.

OBJECTIVE

To explore how patients with CIA conceive their own influence on a good treatment response to biological therapy.

METHODS

This study had an exploratory and descriptive design with a phenomenographic approach. Interviews were conducted with 25 patients (11 women and 14 men) aged 17-79 years, with CIA who were undergoing biological therapy and who had low disease activity or were in remission.

RESULTS

Patients with CIA undergoing biological therapy conceived their own influence on good treatment response in terms of adherence, physical activity, mental attitude, social support, and self-awareness. Adherence was described as the foundation for the patients' own influence on good treatment response. Physical activity, mental attitude, and social support reflected three essential ways of understanding patients' influence on good treatment response where the patients spoke about physical strength, mental strength, and social strength. Self-awareness reflected a comprehensive way of influencing good treatment response in which patients balanced their physical, mental, and social resources in partnership with health care professionals.

CONCLUSION

Patients conceived that they had a responsibility for adhering to the treatment as well as achieving balance in life in order to ensure good treatment response. Self-awareness was essential for maintaining a good treatment response, and this reflected the patients' awareness of the complexity of living their lives with a chronic illness.

Effects of Nursing Interventions on Depression of Patients With Rheumatoid Arthritis: A Meta-Analysis of Randomized Controlled Trials

INTRODUCTION

Previous randomized controlled trials have led to conflicting findings regarding the effects of nursing interventions on depression of patients with rheumatoid arthritis (RA). The purpose of this study was to use the meta-analytic approach to resolve these discrepancies.

METHODS

We performed a systematic search of publications using MEDLINE, EMBASE, the Cochrane Library, and manual searches without language restrictions. Studies that met the following criteria were included: (1) randomized controlled trials; (2) duration of intervention≥4 weeks; (3) comparative control group; (4) adults with RA; (5) published studies in any language since reception; and (6) psychological symptoms assessed. We extracted relative risks (RRs) and 95% confidence internals (CIs) and pooled them using a random effect model. We carried out sensitivity analysis and assessed heterogeneity and publication bias.

RESULTS

A total of 14 studies, including 1803 patients, were eligible for inclusion in the review. Depression symptom was assessed by questionnaires. In the pooled analysis, nursing interventions, including exercise training, medication guide, health education and psychotherapy were associated with the remission of depression (RR: -0.67; 95% CI: -0.89 to -0.46; P<0.01) with significant heterogeneity between studies (P<0.01).

CONCLUSION

Nursing interventions may be important adjunctive therapies in the medical management of RA patients.

Impact of Treatment-Related Beliefs on Medication Adherence in Immune-Mediated Inflammatory Diseases: Results of the Global ALIGN Study

INTRODUCTION

Medication adherence is critical in chronic immune-mediated inflammatory diseases (IMIDs) and could be affected by patients' treatment-related beliefs. The objective of this study was to determine beliefs about systemic medications in patients with IMIDs and to explore the association of those beliefs and other factors with adherence.

METHODS

This was a multi-country, cross-sectional, self-administered survey study. Included were adults diagnosed with one of six IMIDs receiving conventional systemic medications and/or tumor necrosis factor inhibitors (TNFi). Patients' necessity beliefs/concerns towards and adherence to treatments were assessed by the Beliefs about Medicines Questionnaire and four-item Morisky Medication Adherence Scale. Correlation of patients' beliefs about treatment and other factors with adherence were evaluated by multivariable regression analyses.

RESULTS

Among studied patients (N = 7197), 32.0% received TNFi monotherapy, 27.7% received TNFi-conventional combination therapy, and 40.3% received conventional medications. Across IMIDs, high adherence to systemic treatment was more prevalent in TNFi groups (61.3-80.7%) versus corresponding conventional treatment groups (28.4-64.7%). In at least four IMIDs, greater perception of the illness continuing forever (P < 0.001), of the treatment helping (P < 0.001), and more concerns about the illness (P < 0.01), but not clinical parameters, were associated with higher treatment necessity beliefs. Higher treatment necessity beliefs, older age, Caucasian race, and TNFi therapy were associated with high medication adherence in at least four IMIDs.

CONCLUSIONS

Treatment necessity beliefs were higher than concerns about current medication in patients with IMID. Illness perceptions had a greater impact on treatment necessity beliefs than clinical parameters. Older age, greater treatment necessity beliefs, and TNFi therapy were associated with high self-reported medication adherence in at least four IMIDs.

Impact of Treatment-Related Beliefs on Medication Adherence in Immune-Mediated Inflammatory Diseases: Results of the Global ALIGN Study

Introduction

Medication adherence is critical in chronic immune-mediated inflammatory diseases (IMIDs) and could be affected by patients’ treatment-related beliefs. The objective of this study was to determine beliefs about systemic medications in patients with IMIDs and to explore the association of those beliefs and other factors with adherence.

Methods

This was a multi-country, cross-sectional, self-administered survey study. Included were adults diagnosed with one of six IMIDs receiving conventional systemic medications and/or tumor necrosis factor inhibitors (TNFi). Patients’ necessity beliefs/concerns towards and adherence to treatments were assessed by the Beliefs about Medicines Questionnaire and four-item Morisky Medication Adherence Scale. Correlation of patients’ beliefs about treatment and other factors with adherence were evaluated by multivariable regression analyses.

Results

Among studied patients (N = 7197), 32.0% received TNFi monotherapy, 27.7% received TNFi–conventional combination therapy, and 40.3% received conventional medications. Across IMIDs, high adherence to systemic treatment was more prevalent in TNFi groups (61.3–80.7%) versus corresponding conventional treatment groups (28.4–64.7%). In at least four IMIDs, greater perception of the illness continuing forever (P < 0.001), of the treatment helping (P < 0.001), and more concerns about the illness (P < 0.01), but not clinical parameters, were associated with higher treatment necessity beliefs. Higher treatment necessity beliefs, older age, Caucasian race, and TNFi therapy were associated with high medication adherence in at least four IMIDs.

Conclusions

Treatment necessity beliefs were higher than concerns about current medication in patients with IMID. Illness perceptions had a greater impact on treatment necessity beliefs than clinical parameters. Older age, greater treatment necessity beliefs, and TNFi therapy were associated with high self-reported medication adherence in at least four IMIDs.

Depression moderates the associations between beliefs about medicines and medication adherence in patients with rheumatoid arthritis: Cross-sectional study

The 'necessity-concerns framework' postulates that patients' adherence behaviour is influenced by beliefs about the necessity and the concerns patients have regarding their prescribed medicines. We hypothesized that depression moderates the associations between beliefs about medicines and medication adherence among people with rheumatoid arthritis. Using multivariate logistic regression, we observed that people experiencing more depressive symptoms showed stronger associations between necessity beliefs and adherence as well as attenuated associations between concerns and adherence, respectively, in a cross-sectional sample ( N = 361). Thus, depression moderates the associations postulated in the 'necessity-concerns framework' in a differential way in people with rheumatoid arthritis.

The necessity-concerns framework predicts adherence to medication in multiple illness conditions: A meta-analysis

OBJECTIVE

This meta-analysis investigated whether beliefs in the necessity and concerns of medicine and the necessity-concerns differential are correlated with medication adherence on a population level and in different conditions.

METHODS

An electronic search of Web of Science, EMBASE, PubMed and CINAHL was conducted for manuscripts utilising the Beliefs about Medicines Questionnaire and comparing it to any measure of medication adherence. Studies were pooled using the random-effects model to produce a mean overall effect size correlation. Studies were stratified for condition, adherence measure, power and study design.

RESULTS

Ninety-four papers were included in the meta-analysis. The overall effect size(r) for necessity, concerns, and necessity-concerns differential was 0.17, -0.18 and 0.24 respectively and these were all significant (p<0.0001). Effect size for necessity was stronger in asthma and weaker in the cardiovascular group compared to the overall effect size.

CONCLUSION

Necessity and concerns beliefs and the necessity-concerns differential were correlated with medication adherence on a population level and across the majority of included conditions. The effect sizes were mostly small with a magnitude comparable to other predictors of adherence.

PRACTICE IMPLICATIONS

This meta-analysis suggests that necessity and concern beliefs about medicines are one important factor to consider when understanding reasons for non-adherence.

Treatment adherence to disease-modifying antirheumatic drugs in Chinese patients with rheumatoid arthritis

OBJECTIVE

Nonadherence in rheumatoid arthritis (RA) patients using disease-modifying antirheumatic drugs (DMARDs) may lead to joint damage and function loss. The aim of this cross-sectional study was to explore Chinese RA patients' adherence rates and investigate potential risk factors for nonadherence.

METHODS

A total of 122 RA patients were recruited from the Affiliated Hospital of Nantong University from January 2014 to April 2015. Patients were asked to complete a set of standardized self-report questionnaires (Compliance Questionnaire on Rheumatology, Health Assessment Questionnaire, Short Form-36 questionnaire, 28-joint Disease Activity Score, Hospital Anxiety and Depression Scale, and Visual Analog Scale). Independent samples t-tests, chi-square analyses, and logistic regression modeling were used to analyze these data.

RESULTS

Based on Compliance Questionnaire on Rheumatology, 38% of the patients adhered to DMARDs. Adherence was associated with education, income, depression, and the total number of DMARDs. Other demographic and clinical characteristics were not associated with adherence. Logistic regression models identified income, depression, and the total number of DMARDs as predictors of medication nonadherence.

CONCLUSION

In this study, 62% of patients with RA were not adherent to their DMARD prescription. Education, income, depression, and the total number of DMARDs were associated with medication adherence, and income, depression, and the total number of DMARDs were independent predictors of medication adherence in patients with RA. These findings could help medical personnel develop helpful interventions to improve adherence in RA patients by paying more attention to the patients with these accompanying risk factors and, finally, improve RA patients' quality of life.

Patient-centred care in established rheumatoid arthritis

Review of the evidence on patient-centred care (PCC) in rheumatoid arthritis (RA) shows that involving the patient as an individual - with unique needs, concerns and preferences - has a relevant impact on treatment outcomes (safety, effectiveness and costs). This approach empowers patients to take personal responsibility for their treatment. Because clinicians are only able to interact personally with their patients just a few hours per year, patients with a chronic condition such as RA should be actively involved in the management of their disease. To stimulate this active role, five different PCC activities can be distinguished: (1) patient education, (2) patient involvement/shared decision-making, (3) patient empowerment/self-management, (4) involvement of family and friends and (5) physical and emotional support. This article reviews the existing knowledge on these five PCC activities in the context of established RA management, especially focused on opportunities to increase medication adherence in established RA.
