Treatment adherence and disease burden of individuals with rheumatic diseases admitted as outpatients to a large rheumatology center in Shanghai, China

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

Introduction

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

Method

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

Results

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

Discussion

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

Sociodemographic and health system factors associated with variations in hospitalization costs for rheumatic diseases in adults aged 45 years and older: A cross-sectional study of provincial health accounts in Jiangsu Province, China

AIM

To report the cost of hospitalization and the associated risk factors for rheumatic diseases in middle-aged and elderly patients in China.

METHODS

The study participants included inpatients from hospitals of various levels in the Jiangsu Province Health Account database in 2016. Participants were selected by using a multistage sampling method. Patients <45 years of age were excluded, and patients hospitalized for rheumatic diseases were identified according to the 10th edition of the International Classification of Diseases. Generalized linear models were used to analyze the sociodemographic characteristics related to the hospitalization costs of patients with rheumatic diseases.

RESULTS

The study included 3696 patients. The average cost of hospitalization for patients with rheumatic diseases was USD 4038.63. Female sex, a long length of stay, age between 65 and 74 years, free medical care, not being covered by the Urban-Rural Residents Basic Medical Insurance, and a high hospital level were associated with high hospitalization costs.

CONCLUSION

This study examined hospitalization costs and relevant influencing factors in middle-aged and elderly patients with rheumatic disease in China. Our findings are useful for further research on costs of disease and the economic evaluation of strategies to prevent rheumatic disease.

Health utility of patients with established rheumatoid arthritis and its influencing factors: a multi-center study in China

To assess the health utility value (HUV) of Rheumatoid Arthritis (RA) patients and its influencing factors in China. A cross-sectional survey was conducted in 8 tertiary hospitals across four capital-cities. The demographic characteristics, patient-reported outcomes including the HUV got by EQ-5D-5L, clinical characteristics, and clinician-reported outcomes of 171 RA patients were collected both from themselves and their physicians. Both the univariate and multivariate analyses were used to assess the potential factors of EQ-5D-5L HUV of the patients. The mean age of the patients was 50.7 years, with female being 64.9% (n = 111). The mean HUV and EQ visual analogue scale score of all patients were 0.586 and 47.3, respectively. The univariate analysis showed that the patients who were female, older, living in rural areas, with lower education level, advanced disease stage, higher the patient's assessment of arthritis pain visual analogue scale (PtAAP-VAS), the patient's global assessment of disease activity visual analogue scale (PtGADA-VAS), and the Physician's global assessment of disease activity visual analogue scale (PhGADA-VAS) scores had significantly lower EQ-5D-5L HUVs. The multivariate analysis further suggested that older age, female, higher body mass index and higher PtGADA-VAS score were statistically significantly related to lower HUVs. The study provided the HUVs for RA patients with different characteristics and outcomes, which could be used in the economic evaluation of interventions for the RA patients. The identified factors could also assist the health care managing and improving the health-related quality of life on RA patients.

Factors associated with non-adherence to medications in systemic lupus erythematosus: Results from a Swedish survey

OBJECTIVE

To identify determinants of medication non-adherence in a Swedish population of systemic lupus erythematosus (SLE).

METHODS

Patients with SLE from Karolinska and Örebro University Hospitals participated in a survey-based cross-sectional study. Demographics, disease activity, organ damage, HRQoL (LupusQol, EQ-5D-5 L), medication non-adherence (<80% on CQR-19 or MASRI) and beliefs about medicines (BMQ) were registered. MASRI was used to report adherence to different drugs/drug classes, categorised into (i) antimalarial agents (AMA), (ii) glucocorticoids and (iii) other SLE medications. Multivariable logistic regression adjusted for age, sex, disease activity and organ damage.

RESULTS

Among 205 respondents, the median age was 52.0 years (IQR: 34.0-70.0), 86.3% were women, 66.8% were non-adherent to their medications according to CQR-19, and 6.6% and 6.3% were non-adherent to AMA and glucocorticoids, respectively, according to MASRI. Positive beliefs about glucocorticoids (OR; 95% CI: 0.77; 0.59-0.99; p = .039) and medications overall (0.71; 0.52-0.97; p = .029) were protective against non-adherence to glucocorticoids. Anxiety/depression (3.09; 1.12-8.54; p = .029), medication concerns (1.12; 1.05-1.20; p < .001) and belief that medications are overused (1.30; 1.15-1.46; p < .001) or harmful (1.36; 1.19-1.56; p < .001) were associated with medication non-adherence (CQR-19); beliefs in the necessity of medications (0.73; 0.65-0.82; p < .001) and positive beliefs in medications were protective (0.72; 0.60-0.86; p < .001). No associations were found between other investigated factors and medication non-adherence.

CONCLUSIONS

Beliefs about medications were a major determinant of medication non-adherence. Patient education may help alleviate the negative impact of misinformation/unawareness on adherence.

Patient self-reported experience and satisfaction with golimumab and etanercept treatments for rheumatic diseases: A cohort study

Golimumab and etanercept both exhibit good efficacy in treating rheumatic diseases, while the patient self-reported measurement of treatment improvement and injection experience lacks sufficient evidence. Hence, this study aimed to compare the satisfaction with disease improvement and injection experience and the level of injection site reactions (ISRs) between golimumab-treated and etanercept-treated patients with rheumatic diseases. A total of 312 patients with rheumatic diseases were serially enrolled. Among them, 158 patients received golimumab (golimumab group); the other 154 patients were treated with etanercept (etanercept group) according to the actual disease status, physician advice, and patient willingness. Satisfaction with disease improvement was assessed using the 7-point Likert scale; satisfaction with injection experience and level of ISRs were both determined by the 5-point Likert scale. Satisfaction degrees with global injection experience (P = .025), injection device (P = .008), injection frequency (P = .010), and injection convenience (P = .003) were superior in the golimumab group to the etanercept group, while satisfaction degrees with global disease improvement, symptom relief, and speed of action did not vary (all P > .050) between the 2 groups. Discomfort (P = .005), swelling (P < .001), pain (P = .028), and burning (P = .035) levels were lower in the golimumab group than in the etanercept group. In addition, among 56 patients with a history of tumor necrosis factor inhibitor treatment before golimumab, 40 (71.4%) patients preferred golimumab to other tumor necrosis factor inhibitor. After switching to golimumab treatment, the level of ISRs in most patients was reduced or comparable. Golimumab achieves a satisfying injection experience and relieves the level of ISRs over etanercept in patients with rheumatic diseases.

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.

Is Toxoplasma gondii infection a concern in individuals with rheumatic diseases? Evidence from a case-control study based on serological diagnosis

Toxoplasma gondii infection in clinical cases of rheumatic diseases is increasing, whereas, the relationship between T. gondii infection and rheumatic diseases is still ambiguous and contradictory. Thus, the present case-control study based on serological diagnosis was carried out to identify the underlying relationship between T. gondii infection and rheumatic diseases in China. Serological results showed that rheumatic patients (17.25%, 79/458) had a significantly higher T. gondii seroprevalence than control subjects (10.70%, 49/458) (p = 0.004). However, the difference in T. gondii seroprevalence among clinical rheumatic disease forms was insignificant. Moreover, disease duration not effect the T. gondii seroprevalence in the included clinical rheumatic patients. Three risk factors (presence of cats at home, blood transfusion history, and consumption of raw shellfish) were identified through multivariate analysis to affect the T. gondii seroprevalence in the included clinical rheumatic patients. In conclusion, these results indicate that the latent T. gondii infection in clinical rheumatic patients should cause alarm and attention in the course of future scientific research or clinical treatment.

Healthcare Costs and Utilization for Patients With Systemic Lupus Erythematosus in China: A National Claims Database Study

OBJECTIVES

This study aimed to describe the healthcare resource utilization (HCRU) and healthcare costs associated with systemic lupus erythematosus (SLE) management in China from the patient's and the payer's perspective.

METHODS

HCRU and medical costs (2017 US dollar [USD]) between January 1 and December 31, 2017, were extracted from the national medical insurance claims database, China Health Insurance Research Association (consisting of claims from all public health insurance schemes in China), for adults with ≥ 1 SLE-related claim. The main analysis group comprised all adults with an SLE diagnosis and claim during 2017 (overall group); the annual subgroup (SLE diagnosis and claim in January 2017) informed annual HCRU and costs.

RESULTS

The overall group consisted of 3645 adults with ≥ 1 SLE-related claim. Outpatient visits constituted 86.9% of healthcare visits. SLE-related healthcare outpatient costs were USD 433 per outpatient, and inpatient costs were USD 2072 per inpatient. Medication costs accounted for 75.0% (USD 42/56) of total costs for outpatient visits and 44.3% (USD 456/1030) for inpatient hospitalizations. Notably, 35.4% of patients had a severe SLE flare; mean SLE-related cost per severe flare was USD 1616. HCRU and costs were similar in the annual subgroup. Female sex, SLE flares, tertiary hospitals, renal involvement, and utilization of anti-infective drugs were associated with higher SLE-related patient costs.

CONCLUSIONS

SLE in China is associated with considerable HCRU and medical costs, especially for patients experiencing severe SLE flares. Preventing organ involvement, infections, flares, and associated hospitalizations may reduce the burden on patients and healthcare providers in China.

Annual Direct Cost and Cost-Drivers of Systemic Lupus Erythematosus: A Multi-Center Cross-Sectional Study from CSTAR Registry

BACKGROUND

To estimate the annual direct costs and cost-drivers associated with systemic lupus erythematosus (SLE) patients in China.

METHODS

A multi-center, cross-sectional study was conducted based on the CSTAR registry. The information on demography and expenditures for outpatient and inpatient visits due to SLE were collected using online questionnaires. These patients' medical records were from the database of the Chinese Rheumatology Information System (CRIS). The average direct costs and 95% confidence interval were estimated using the bootstrap method with 1000 bootstrap samples by resampling with replacement. The cost-drivers were identified using multivariate regression models.

RESULTS

A total of 1778 SLE patients from 101 hospitals participated in our study, with 92.58% as females, a mean age of 33.8 years old, a median duration of SLE of 4.9 years, 63.8% in an active disease state, 77.3% with two organs or more damaged, and 8.3% using biologics as treatment. The average annual direct cost per patient was estimated at CNY 29,727, which approximates to 86% for direct medical costs. For moderate to severe disease activities, the use of biologics, hospitalization, treatment of moderate or high dose glucocorticoids, and peripheral vascular, cardiovascular, and/or renal system involvements were found to substantially increase the direct costs, while health insurance slightly decreased the direct costs of SLE.

CONCLUSIONS

This study provided reliable insight into financial pressures on individual SLE patients in China. The efforts focusing on preventing flare occurrences and limiting disease progression were recommended to further reduce the direct cost of SLE.

Attitudes towards adherence and deprescribing among polypharmacy patients: a cross-sectional study

Objectives

Deprescribing is the process of optimization of medication regimens through cessation of potentially inappropriate or unnecessary medications or adjustment of doses with the goal of managing polypharmacy and improving outcomes. Deprescribing potentially improves adherence by reducing polypharmacy. This study aimed to assess polypharmacy patients’ adherence attitudes and their attitudes towards deprescribing.

Methods

A cross-sectional study that targeted polypharmacy patients at outpatient clinics at King Abdullah University Hospital. The inclusion criteria were (1) patients ≥18 years old, (2) patients taking five or more medications, and (3) patients who do not require a caregiver or assistance at home. We excluded patients that showed any signs of moderate or severe cognitive impairment. Patients who met the inclusion/exclusion criteria were interviewed by a clinical pharmacist and completed two survey instruments: revised Patients’ Attitudes Toward Deprescribing (rPATD) and Adherence Attitude Inventory (AAI).

Key findings

In total, 501 patients took part in this study. Over half of the participants were not satisfied with their current medicines and over 70% of them perceived that their current medications are a burden to them and would like their prescribers to initiate deprescribing. The majority of the participants have low to medium adherence attitudes primarily due to ineffective patient–provider communication. Logistic regression analysis revealed that self-efficacy, commitment to adherence, education and age were significantly associated with participants’ willingness to stop one or more of their medications.

Conclusions

Our findings suggest that polypharmacy patients have negative attitudes towards their medication therapy and favour deprescribing. These reported attitudes had been associated with negative adherence attitudes. Study findings offer schematic direction for future investigations of the role of adherence on key health-related outcomes in patients on polypharmacy. Furthermore, research is warranted to investigate the impact of deprescribing on polypharmacy patients’ medication adherence.

Reliability and validity of the Chinese version of the eight-item Morisky Medication Adherence Scale in Chinese patients with systemic lupus erythematosus

OBJECTIVE

To evaluate the reliability and validity of the Chinese version of the eight-item Morisky Medication Adherence Scale (MMAS-8) in Chinese patients with systemic lupus erythematosus (SLE).

METHODS

The survey was conducted with a consecutive sampling of 158 Chinese SLE patients attending public hospitals from January to March 2021. We used the translated Chinese version of the MMAS-8 to collect related data. Reliability, item, and factor analyses were used to test the reliability and validity of the MMAS-8 scale in the selected patients. The internal consistency reliability was evaluated using Cronbach's α coefficient. Test-retest reliability was assessed using intraclass correlation coefficients (ICCs) in a subset of 30 participants. Construct validity was evaluated using confirmatory factor analysis and correlations between the Self-efficacy for Appropriate Medication Use Scale (SEAMS) and related measures.

RESULTS

The internal consistency reliability of the Chinese version of the MMAS-8 was high (Cronbach's α = 0.817), and the test-retest reliability was excellent (intraclass correlation = 0.947; P < 0.001). There were significant differences in the F test and t test between the two extreme groups before and after the ranking of 27% of the questionnaire scores (P < 0.001). The Kaiser-Meyer-Olkin (KMO) value of construct validity was 0.860. The spherical test value of Bartlettgers was 417.8822. Factor analysis yielded three components that accounted for 69.375% of the total variance. Exploratory factor analysis identified three dimensions of the Chinese version of the MMAS-8. In terms of criterion validity, the correlation of the MMAS-8 score in SEAMS indicated that the convergent validity was good (r = 0.926; P < 0.001).

CONCLUSIONS

This study shows that the Chinese version of the Medication Adherence Scale-8 is a reliable and valid tool for assessing medication adherence in Chinese SLE patients. Key Points • Many factors affect medication adherence in SLE patients. • Many questionnaires measure medication adherence levels. • There is a lack of reliable validation of medication adherence questionnaires specifically for SLE patients.

Treatment for Severe Lupus Nephritis: A Cost-Effectiveness Analysis in China

Background: Lupus nephritis (LN) is the most common secondary glomerular diseases that will cause end-stage renal disease (ESRD) and renal-related death. The cost-effectiveness of various treatments for LN recommended by official guidelines has not been investigated in China. Our study is to evaluate clinical prognosis and cost-effectiveness of the current treatments for severe LN. Methods: A Markov model was simulated for 1,000 LN patients of 30 years old, over a 3-years and 30-years lifetime horizon respectively. We assessed the cost-effectiveness of six therapeutic strategies from a societal perspective, with cyclophosphamide (CYC) or mycophenolate mofetil (MMF) induction therapy followed by CYC, MMF or azathioprine (AZA) maintenance therapy. Main outcomes included quality-adjusted life years (QALYs), incremental cost-effectiveness ratio (ICER) and clinical prognosis. One and three times gross domestic product (GDP) per capita were used as the willingness-to-pay (WTP) thresholds. We also carried out sensitivity analysis under a lifetime horizon. Results: Compared with the baseline strategy of CYC induction and maintenance, for a 3-years horizon the most cost-effective strategy was CYC induction and AZA maintenance with $448 per QALY gained, followed by MMF induction and AZA maintenance which however was not cost-effective under the one times GDP per capita WTP threshold. For a lifetime horizon, CYC induction and AZA maintenance remained the most cost-effective strategy but MMF induction and maintenance became cost-effective under the one times GDP per capita WTP threshold and achieved a higher complete remission rate (57.2 versus 48.9%) and lower risks of ESRD (3.3 versus 5.8%) and all-cause mortality (36.0 versus 40.8%). The risk of developing ESRD during maintenance was the most influential parameter affecting ICER. Conclusions: The strategy of CYC induction followed by AZA maintenance was the most cost-effective strategy in China for short-term treatment, while the strategy of MMF in both induction and maintenance became cost-effective and yielded more desirable clinical outcomes for lifetime treatment. The uncertainty analysis supported the need for monitoring the progression to ESRD.

Translation and validation of the Chinese version of the general medication adherence scale (GMAS) in patients with chronic illness

OBJECTIVE

To translate the English version of general medication adherence scale (GMAS) into a Chinese version and test its reliability and validity in Chinese patients with chronic diseases.

METHODS

After translating the original English version into Chinese (GMAS-C) following the forward-backward translation and expert review procedure, we conducted a pilot study among 10 chronic disease patients. Each patient took about 10 min to complete the scale and was asked about the difficulty of understanding or filling the scale. Then a total of 312 patients aged 18 years or older with chronic illness were selected from the outpatient departments of two tertiary hospitals and a community center in Tianjin from April 2019 to May 2020 by convenience sampling. Cronbach's α coefficient, item-total correlation and test-retest reliability were used to evaluate the scale reliability; expert evaluation method was used to evaluate the content validity of the scale; and exploratory factor analysis, confirmatory factor analysis, and known group validity were used to evaluate the construct validity of the scale.

RESULTS

As a result of the adaptation process, the GMAS-C's structure was determined. It included 3 dimensions and 11 items and was reliable and valid for Chinese patients with chronic diseases. Total Cronbach's α coefficient of the scale was 0.781 and test-retest reliability coefficient was 0.883 after two weeks. The item-level content validity indexes (CVIs) were ≥ 0.78 for all items. A Kaiser-Meyer-Olkin test and Bartlett' test of sphericity test indicated that the sample met the requirements of factor analysis. Exploratory factor analysis extracted three factors with eigenvalue >1, and 60% of the total variance was explained by three-factor solution. Confirmatory factor analysis showed acceptable fit indices (χ²/df = 1.58, IFI = 0.96, TLI = 0.94, CFI = 0.96 and RMSEA = 0.05).

CONCLUSIONS

The GMAS-C demonstrates satisfactory reliability and validity. This scale can be a clinically useful tool to identify the levels of medication adherence and possible barriers for adherence of the medication regime in patients with chronic diseases.

Investigating the safety and compliance of using csDMARDs in rheumatoid arthritis treatment through face-to-face interviews: a cross-sectional study in China

Rheumatoid arthritis (RA) significantly impacts the health of Chinese patients. Conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) are used as the standard treatment for patients with RA. However, Chinese patients with RA have reported poor compliance with csDMARDs. This study aims to better understand the safety and compliance of using csDMARDs in RA treatment. Face-to-face interviews were conducted by questionnaires on safety and compliance of csDMARDs in 400 patients with RA and 100 rheumatologists from 13 cities in China. Rheumatologists were from Tier 3 Class A hospitals with independent rheumatology departments, who admitted more than 30 patients with RA per week. All patients were diagnosed for > 3 months before the survey and had been treated with csDMARDs for > 3 months. The incidence of adverse events (AEs) that attributed to csDMARDs estimated by rheumatologists was lower than that reported by patients for all four prescribed csDMARDs. Also, types of common AEs in rheumatologist's perception differed from those in the patient's report. Only 86% (116/135) of patients claimed they notified their rheumatologist about AEs, and 40.8% (150/368) of patients did not strictly adhere to their prescribed treatment. Reasons why patients were not compliant with their treatment, other than AEs, included symptoms being less severe, travel, and busy working life/business trips. This study revealed gaps in perceptions of csDMARDs-related AEs and medication adherence between rheumatologists and patients. These findings suggested adequate doctor-patient communications, and considerations of multiple real-world situations may improve adherence in the treatment of RA patients. Key Points • This study identified gaps in rheumatologists' perception of the prevalence and type of AEs experienced by their patients, which could potentially help them improve their patients' compliance with treatment.

Assessment of the effects of loneliness, perceived social support, and depression on medication adherence in patients with ankylosing spondylitis

PURPOSE

This study aims to investigate the effects of loneliness, perceived social support, and depression on medication adherence of patients with ankylosing spondylitis (AS).

DESIGN AND METHODS

This cross-sectional study was conducted with 119 AS patients. Data were collected using the Morisky-Green-Levine Medication Adherence Scale, the UCLA Loneliness Scale (ULS), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Beck Depression Inventory (BDI).

FINDINGS

Nonadherent patients were younger (P = .033), scored higher on the ULS (P = .015), and BDI (P = .024) scales, and lower on the MSPSS scale (P = .039) and on family support (P = .002).

PRACTICAL IMPLICATIONS

The biopsychosocial aspects of patients with AS should be managed holistically to improve their medication adherence.

Health-related quality of life in rheumatoid arthritis: Systematic review and meta-analysis of EuroQoL (EQ-5D) utility scores from Asia

INTRODUCTION

Region-specific health-related quality of life (HRQoL) scores or utility values are representative and pivotal for economic evaluations as they are influenced by the value judgment of the local population. This study systematically reviewed and pooled EuroQoL-5 Dimension (EQ-5D) utility scores of rheumatoid arthritis (RA) across primary studies from Asia.

METHODS

Studies reporting EQ-5D utility scores among adult RA patients from Asian countries were systematically searched in PubMed-Medline, Scopus and Embase since inception through February 2020. Selected studies were systematically reviewed and study quality assessment was performed. Meta-analysis was performed using a random-effect model with subgroup and meta-regression analysis to explore heterogeneity.

RESULTS

Among 1391 searched articles, 37 studies with 31 983 participants were systematically reviewed and meta-analysis was conducted among 31 studies. The pooled EQ-5D scores and EQ-5D visual analog score were 0.66 (95% CI 0.63-0.69, I²  = 99.65%) and 61.21 (50.73-71.69, I²  = 99.56%) respectively with high heterogeneity. For RA patients with no, low, moderate and high disease activity based on Disease Activity Score (DAS)-28, the pooled EQ-5D scores were 0.78 (0.65-0.90), 0.73 (0.65-0.80), 0.53 (0.32- 0.74), and 0.47 (0.32-0.62), respectively. On meta-regression, age of patients (P < .05) was positively associated and use of glucocorticoids (P < .05) was inversely associated with utility values.

CONCLUSION

Lower EQ-5D scores were associated with severe disease activity, increasing age and female gender among RA patients. The study provides pooled EQ-5D scores for RA patients that are useful inputs for cost-utility studies in Asia.

Current, New and Future Therapeutic Targets in Inflammatory Bowel Disease: A Systematic Review

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are chronic relapsing conditions resulting from immune system activity in a genetically predisposed individual. IBD is based on progressive damage to the inflamed gut tissue. As its pathogenesis remains unknown, recent accumulating data have demonstrated that IBD is a complex and multi-factorial disorder correlated with host luminal factors, which lead to an imbalance between pro- and anti-inflammatory signaling. The growing understanding of the molecular mechanisms responsible for IBD has suggested a wide range of potential therapeutic targets to treat this condition. Some patients do not have a satisfactory response to current therapeutic medications such as antitumor necrosis factor (TNF) agents, or their response decreases over time. As a result, IBD therapeutics have been changed recently, with several new agents being evaluated. The identification of various inflammatory cascades has led to forming the idea to have novel medications developed. Medications targeting Janus kinases (JAK), leukocyte trafficking Interleukin (IL) 12/23, and Sphingosine 1 phosphate (S1P) are among these newly developed medications and highlight the role of microbial-host interaction in inflammation as a safe promising strategy. This systematic review aims to summarize different molecular targeting therapeutics, the most potent candidates for IBD treatment in recent studies.

Methotrexate (MTX) Plus Hydroxychloroquine versus MTX Plus Leflunomide in Patients with MTX-Resistant Active Rheumatoid Arthritis: A 2-Year Cohort Study in Real World

Purpose

To compare the efficacy, safety, and cost-effectiveness of methotrexate (MTX) plus hydroxychloroquine (HCQ) vs MTX plus leflunomide (LEF) in established rheumatoid arthritis (RA) with inadequate response to MTX monotherapy in a real-world Chinese cohort.

Patients and Methods

A prospective RA cohort (n=549) was screened with eligible patients who had inadequate response (disease activity score in 28 joints using erythrocyte sedimentation rate, DAS28-ESR>3.2) to initial MTX monotherapy and subsequently received either MTX+HCQ or MTX+LEF. Propensity score matching (PSM) was applied to adjust the possible baseline confounders between two groups. The primary outcome was the proportion of patients achieving first remission (DAS28-ESR<2.6) during follow-up by log rank test. Secondary outcomes were changes of DAS28, glucocorticoids (GCs) exposure, safety, cost-effectiveness, sustained remission, and low disease activity (LDA) rate after 24-month follow-up.

Results

Overall, 222 eligible patients were subjected to the aforementioned two treatment protocols (MTX+HCQ, n=102; MTX+LEF, n=120). After PSM adjustment, 97 patients in each group were analyzed. A higher remission rate was observed in the MTX+HCQ group than in the MTX+LEF group (70.1% vs 56.7%, P=0.048). The median time to remission was 11 and 16 months in the two groups, respectively. At the endpoint, more patients achieved remission (46.8% vs 32.5%, P=0.063) and maintained sustained LDA in the HCQ group (53.2% vs 38.6%, P=0.062) and also more patients withdrew GCs in this group (32% vs 16.7%, P=0.053) than those in the LEF group. Safety profiles were non-alarming, with no significant difference between the two groups. The incremental cost-effectiveness ratio yielded by MTX+HCQ over MTX+LEF was $1,111.8 per quality-adjusted life-year (QALY), within the cost-effective threshold set as the per capita gross domestic product (GDP) of China.

Conclusion

The MTX+HCQ combination was seemingly superior to MTX+LEF in a real-world cohort of Chinese RA patients with inadequate response to methotrexate monotherapy in respect of the efficacy and cost-effectiveness.

Use of complementary and alternative medicine in patients with ankylosing spondylitis

OBJECTIVE

Some studies have shown that the use of complementary and alternative medicine (CAM) is common in patients with chronic painful conditions, such as ankylosing spondylitis (AS). This study aimed to determine the prevalence and types of CAM usage in patients with AS and to evaluate the impact of treatment adherence and beliefs about medicines on CAM usage.

METHODS

This study has a descriptive design. A total of 140 patients with AS were included. The treatment adherence of the patients was evaluated using the Morisky Green Levine Medication Adherence Scale. The Beliefs about Medicines Questionnaire (BMQ-T) was used to assess patients' beliefs about medicines.

RESULTS

Previous or current CAM usage was stated by 40% of the patients. It has been found that CAM usage was significantly high (p<0.05) in patients who were married, older, and diagnosed at older ages. The difference between patients' beliefs about medicines and CAM usage was not statistically significant (p>0.05). The BMQ-T scores were significantly different in terms of the patients' treatment adherence (p<0.05).

CONCLUSION

This study showed that approximately half of the patients with AS were using 1 CAM method. Furthermore, medication adherence and patients' beliefs about medicines did not have any impact on CAM usage, but the patients' beliefs about medicines affected treatment adherence.

Rate and causes of noncompliance with disease-modifying antirheumatic drug regimens in patients with rheumatoid arthritis

INTRODUCTION/OBJECTIVES

To determine the prevalence and factors associated with medication noncompliance by Thai patients with rheumatoid arthritis (RA).

METHODS

This prospective cohort study enrolled 443 adult RA patients (≥ 18 years) who were followed up at the outpatient rheumatology clinics of Siriraj Hospital and Phramongkutklao Hospital between May 2018 and December 2019. Medication noncompliance was assessed using the Compliance Questionnaire for Rheumatology-19 (CQR-19). A score of 0 indicated complete noncompliance, whereas a score of 100 indicated a perfect compliance. An unsatisfactory compliance was arbitrarily defined as a taking compliance of ≤ 80%.

RESULTS

The prevalence of medication noncompliance was 22.1%. The most common cause was forgetting to take medications due to a busy work schedule. In a univariate analysis, the factors that were significantly related to medication noncompliance were age, income, number of comorbidities, functional status as measured by the Health Assessment Questionnaire (HAQ), number of prescribed pills per day, and number of types of prescribed medications per day. In a subsequent backward stepwise multiple logistic regression analysis, only 2 factors were found to be negatively associated with medication noncompliance: age (risk ratio, 0.98; 95% CI, 0.96-0.99; p, 0.048) and HAQ (risk ratio, 0.62; 95% CI, 0.39-0.98; p, 0.041).

CONCLUSIONS

Medication noncompliance is common in patients with RA. As this may lead to unfavorable outcomes, patient education related to drug compliance should be addressed and emphasized in daily practice. Key Points • Medication noncompliance is common in patients with RA. • Forgetting to take pills was the most frequent explanation offered for noncompliance. • All patients should be strongly encouraged to comply with the recommended drug regimens.

Systemic Lupus Erythematosus: Targeted literature review of the epidemiology, current treatment and disease burden in the Asia Pacific region

OBJECTIVE

To understand the epidemiology, current treatment and disease burden of systemic lupus erythematosus (SLE) in the Asia Pacific region (APAC).

METHODS

A targeted literature review of published evidence on SLE in APAC was conducted, using the MEDLINE® database (2008-2018), conference proceedings and other supplementary sources.

RESULTS

The review identified 70 studies conducted in China (n=15), Japan (n=13), Taiwan (n=12), Korea (n=9), Australia (n=7), Hong Kong (n=6), Singapore (n=4), and multiple places within the APAC region (n=4). Incidence rates (per 100,000 per year) ranged from 0.9-8.4, while prevalence rates ranged from 3.7-127 (per 100,000); however, recent data was limited. Asian SLE patients were reported to have higher disease severity, activity (higher SLE disease activity index scores) and organ damage accrual; along with increased morbidity, mortality, and susceptibility to renal involvement compared with other ethnicities in APAC. The risk of developing SLE is higher in the Asian population. Routinely used SLE therapies included belimumab, hydroxychloroquine, cyclophosphamide, tacrolimus, azathioprine, mycophenolate mofetil, and corticosteroids; however, prescribing patterns varied across the region. Increased disease activity was associated with high economic burden and poor quality of life for SLE patients in APAC.

CONCLUSION

SLE remains a disease with a significant unmet medical need for an innovative therapy that is well-tolerated and effective for patients in APAC. Further evidence is required to better characterize the disease and fully capture the burden and impact of SLE in APAC. This review has highlighted where there is a paucity of data from patients across the APAC region.

Multidisciplinary care in patients with systemic lupus erythematosus: a randomized controlled trial in China

Background For the large number of systemic lupus erythematosus (SLE) patients in China, it is critical to carry out effective disease management to improve the treatment effect and reduce disease burden. A pharmacist-led multidisciplinary care model has not been reported in Chinese SLE patients before. Objective To assess the effect of patient-centered, pharmacist-led, multidisciplinary care on clinical outcomes and satisfaction with health care in Chinese SLE patients. Setting: The South Campus, Renji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China. Method Participants were 143 systemic lupus erythematosus patients randomly assigned to either the intervention group (multidisciplinary care: physician, pharmacist and nurse) or the control group (usual care only). Main outcome measures The primary outcome was scores on the systemic lupus erythematosus disease activity index-2000, the satisfaction with information about medicines scale, and the EuroQol five-dimension questionnaire, assessed at baseline and 12 months. Results Between October 1, 2017 and October 1, 2018, 42 participants were included in the intervention group and 40 in the control group. At 12 months, results for the systemic lupus erythematosus disease activity index-2000 differed significantly between the intervention group and the control group (0 vs. 2, P = 0.027). Patient satisfaction with health care was also significantly greater in the intervention group than in the control group (92.9 vs. 0%, P = 0.000). According to the EuroQol five-dimension questionnaire, health quality was also improved (0.94 vs. 0.85, P = 0.006). Conclusion Our multidisciplinary care team significantly improved clinical outcomes and satisfaction with drug information in Chinese systemic lupus erythematosus patients.

Lack of patient education is risk factor of disease flare in patients with systemic lupus erythematosus in China

BACKGROUND

To explore the inadequacies of health service and its impact on clinical outcomes of patients with systemic lupus erythematosus (SLE) in China.

METHODS

A total of 210 SLE patients were randomly recruited between January 2017 and January 2018. Each patient received self-report questionnaires to assess medication adherence [Compliance Questionnaire for Rheumatology (CQR)], beliefs about medicines [Beliefs about Medicines Questionnaire (BMQ)] and satisfaction about medicine information [the Satisfaction with Information about Medicines Scale (SIMS)]. Associations between SLE disease activity index (SLEDAI-2 K) and observed factors were analyzed by multiple logistic regression.

RESULTS

Based on CQR, only 28.10% patients were adherent. The score of BMQ was 2.85 ± 5.42, and merely 32.38% patients were satisfied with the information about their prescribed medicines. Disease activity was associated with SIMS, EuroQol five-dimensions [EQ5D], Systemic Lupus International Collaborating Clinics (SLICC), depression, use of NSAID (P ≤ 0.05). Remission of disease was positively correlated with SIMS (OR = 0.16, 95% CI: [0.06, 0.40]), and BMQ (OR = 0.64, 95%CI: [0.43, 0.94]).

CONCLUSION

In this study, the scores of BMQ and SIMS were low, implying defects in the patient education of health service system, which led to disease flare in Chinese SLE patients.

Evaluation of treatment adherence in patients with Behçet's disease: its relation to disease manifestations, patients' beliefs about medications, and quality of life

INTRODUCTION/OBJECTIVES

Despite its importance, adherence to treatment has not been sufficiently studied in Behçet's disease (BD). The aim of this study was to evaluate medication adherence in BD using the Compliance Questionnaire of Rheumatology (CQR) and factors potentially affecting it.

METHOD

This cross-sectional study included 67 consecutive BD patients including 57 (85%) males with a mean age of 35.1 ± 9.27 years and mean disease duration of 129 ± 91 months. The cumulative clinical manifestations, the Behçet's Disease Current Activity Form (BDCAF) score, and the Vasculitis Damage Index (VDI) were recorded. The CQR, Socioeconomic Status Questionnaire for Health Research in Egypt (SES), the Beliefs about Medication Questionnaire (BMQ), and the Short Form 36 (SF-36) quality of life assessment questionnaire were administered to the patients. Linear regression analysis was done to determine independent predictors of CQR.

RESULTS

The mean BDCAF score was 3.27 ± 3.54 and the VDI was 3.36 ± 2.21. The mean CQR score was 69.2 ± 11.79. The CQR score varied significantly among different health sources (p = 0.02), with no relationship detected with other sociodemographic characteristics, nor with clinical characteristics or the SF-36. Among the investigated medications' complexities, severity of side effects showed significantly different CQR scores (p = 0.004), and a weak positive correlation between medications' numbers and the CQR was detected. Predictors for higher CQR scores included the necessity beliefs score of the BMQ (β = 1.1, p < 0.001); whereas, predictors for lower CQR scores were the harm and concern BMQ subscales ((β = - 1.5, p = 0.004) and (β = - 0.72, p = 0.032), respectively).

CONCLUSIONS

Beliefs about medications were the only predictor for adherence in our cohort.
