RESUMEN
OBJECTIVES: The aim of this study was to update the Japan College of Rheumatology (JCR) clinical practice guidelines (CPGs) for the management of rheumatoid arthritis (RA) and prepare an algorithm for non-drug and surgical treatments. This article is a digest version of the guidelines. METHODS: The Japanese Ministry of Health, Labour and Welfare's research group, in collaboration with the JCR, used the Grading of Recommendations, Assessment, Development, and Evaluation method to update the 2014 JCR CPG for RA. The consensus was formed by CPG panel members. RESULTS: We raised 19 clinical questions regarding non-drug and surgical treatments for RA and developed recommendations. The treatments included exercise therapy; occupational therapy; joint injection of corticosteroids; and orthopaedic surgeries including cervical spine surgery, wrist and foot arthroplasty, ankle arthrodesis, and replacement arthroplasty of the shoulder, elbow, finger, hip, knee, and ankle. Recommendations regarding the risks of surgery and perioperative discontinuation of medications have also been developed. Based on these recommendations, we created an original algorithm for the non-drug and surgical treatment of RA. CONCLUSIONS: These recommendations are expected to serve rheumatologists, health care professionals, and patients with RA as tools for shared decision-making to treat residual limb joint symptoms and functional impairment.

OBJECTIVE: The aim of this study was to update the Japan College of Rheumatology (JCR) clinical practice guidelines (CPG) for the management of rheumatoid arthritis (RA; JCR CPG for RA) according to recent changes in the medical environment in Japan. This article is a digest version of the guidance. METHODS: We used the Grading of Recommendations, Assessment, Development, and Evaluation method to update the 2014 JCR CPG for RA. A consensus was formed by CPG panel members. RESULTS: We identified 36 important clinical questions regarding drug treatment and developed corresponding recommendations for RA. The recommendations included the following RA medications: non-steroidal anti-inflammatory drugs, corticosteroids, conventional synthetic disease-modifying antirheumatic drugs, biological disease-modifying antirheumatic drugs, anti-receptor activator for nuclear factor-κB ligand antibodies, and Janus kinase inhibitors, as well as the tapering and discontinuation of these medications. Recommendations regarding the efficacy and safety of treatments in the elderly and patients with comorbidities were also developed. Finally, we used these recommendations to create an original algorithm for drug treatment for RA based on the Treat-to-Target approach. CONCLUSION: The 2020 JCR CPG for RA provides a useful tool for rheumatologists, health care professionals, and patients with RA, enabling shared decision-making in a variety of clinical situations.

OBJECTIVE: This study aimed to evaluate satisfaction with total joint replacement (TJR) surgery among patients with rheumatoid arthritis (RA). METHODS: We mailed questionnaires to randomly selected members of the Japan Rheumatism Friendship Association, stratified by age and prefecture, throughout Japan. The questionnaire collected demographic and clinical characteristics as well as patients' satisfaction with TJR and their current therapy. RESULTS: Of the 1156 patients who returned the questionnaire, 339 (29.3%) responded that they had had TJR of any type. The mean age was 66.6 years, and 94.4% were women. The mean time period from the hip and knee TJR was 14-15 years. Over half of the patients who had had TJR were satisfied with the results, especially those who had had hip (89.6%) and knee TJR (87.3%), who reported a high level of satisfaction. Multivariable linear regression analysis revealed that, in patients with knee TJR, satisfaction with current therapy was significantly related to whether they were satisfied with the results of the surgery. CONCLUSION: Most patients with RA who had undergone TJR were satisfied with the results even after a long period of time, and their level of satisfaction was associated with their satisfaction with current therapy.

OBJECTIVES: To evaluate the efficacy and safety of biosimilars compared with reference biological disease modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA) as a part of the process of developing the 2020 update of the Japan College of Rheumatology guidelines for the management of RA. METHODS: PubMed, Cochrane Library, and Japan Centra Revuo Medicina were searched for articles to conduct a systematic review (SR). The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation system. RESULTS: Twenty randomized controlled trials were included (biosimilars of infliximab, etanercept, and adalimumab). A meta-analysis revealed that the risk ratios (RRs) and 95% confidence intervals (CIs) of achieving the American College of Rheumatology 50% response (ACR50) at week 24 and serious adverse events (SAEs) for biosimilars compared with the reference bDMARDs were 1.04 (0.98-1.10) and 0.84 (0.61-1.18), respectively. The RRs of achieving ACR50 and SAEs at week 24 were respectively 0.93 (0.69-1.26) and 2.15 (0.55-8.35) in the patients who switched to biosimilars from the reference bDMARDs and 0.92 (0.76-1.12) and 1.41 (0.32-6.15) in those who continued the reference bDMARDs. CONCLUSION: Biosimilars and reference bDMARDs were equally useful for the management of RA.

OBJECTIVES: This study aimed to evaluate the impact of exercise therapy on patient-reported outcomes (PROs) in rheumatoid arthritis (RA) as part of the process of updating the 2020 Japanese guidelines for the management of RA according to the Grading of Recommendations, Assessment, Development, and Evaluation system. METHODS: We searched PubMed, Japana Centra Revuo Medicina Web, and the Cochrane Library (from 2009 to 2018) to identify articles that evaluated PROs of exercise therapy and RA disease activity. RESULTS: A total of 662 articles were identified, including nine RCTs, and meta-analyses were performed on six RCTs on systemic exercise therapy and three RCTs on upper extremity exercise therapy. Analyzed exercise therapies were diverse, differing in target population, intervention method, and duration. Significant improvements were observed in the Health Assessment Questionnaire Disability Index (mean difference -0.35, 95% confidence interval (CI): -0.60 to -0.10), pain (standardized mean difference -2.04, 95% CI: -3.77 to -0.32), and SF-36. For upper extremity exercise therapy, significant improvements in PROs (Disabilities of the Arm, Shoulder, and Hand Questionnaire, Michigan Hand Outcome Questionnaire) were observed. CONCLUSION: Exercise therapy in RA treatment improves patient subjective assessment of pain, physical function, and quality of life.

OBJECTIVES: To provide an evidence base for clinical practice guidelines (CPG) for the management of rheumatoid arthritis (RA) in older adults. METHODS: PubMed, Cochrane library, and Japan Centra Revuo Medicina databases were searched for articles published between 1990 and 2019. Quality of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation system, with some modifications. RESULTS: Among 702 identified articles, there were 5 post-hoc analyses of randomized controlled trials and 10 observational studies. Meta-analysis of the former yielded a mean difference of the van der Heijde-modified total Sharp score of -2.79 (95% confidence interval [CI] - 3.74 to -1.84) for treatment with tumor necrosis factor inhibitors. The risk ratio (RR) for the American College of Rheumatology 50% response rate, and for serious adverse events was 2.83 (95%CI 1.90-4.21) and 1.32 (95%CI 0.53-3.31), respectively, for Janus kinase inhibitors. Meta-analysis of the observational studies yielded an RR for disease activity score-28 remission and serious infections of 0.76 (95%CI 0.64-0.91) and 1.92 (95%CI 1.31-2.81) for older-versus-younger patients receiving biological disease-modifying antirheumatic drugs, respectively. CONCLUSION: This systematic review provides the necessary evidence for developing CPG for the management of RA in older adults.

OBJECTIVES: This study aimed to evaluate patients' opinions regarding their rheumatoid arthritis (RA) therapy and to reflect the patients' perspectives in the 2020 update of the Japan College of Rheumatology clinical practice guidelines. METHODS: A self-administered questionnaire was mailed to 1600 members of the Japan Rheumatology Friendship Association, who were randomly selected by age and prefecture. RESULTS: A total of 1156 patients returned the questionnaire (response rate, 72.3%; mean age, 63.0 ± 11.9 years). Those who reported having discussed their treatment goals with their doctors (450 respondents, 38.9%) were more likely to be satisfied with their current medical care (odds ratio, 7.13; 95% CI 4.72-10.8) compared with those who had not discussed their goals nor had them explained (287 respondents, 24.8%). The benefits exceeded the adverse effects for all pharmacotherapy (methotrexate, corticosteroids, conventional synthetic antirheumatic drugs, biological agents, Janus kinase inhibitor, and anti-RANKL antibodies). However, while 74.2% of the respondents using biological agents perceived that 'the favorable aspects outweighed the unfavorable aspects,' most of those taking anti-RANKL antibodies (69.2%) felt uncertain. CONCLUSIONS: The questionnaire successfully collected information regarding patients' perceptions regarding their therapy. Further implementation of treat-to-target is necessary in Japan to improve patient satisfaction.

OBJECTIVES: To examine the risk factors of surgical site infection (SSI), delayed wound healing, and death after orthopedic surgery in patients with rheumatoid arthritis (RA). METHODS: We identified articles indexed in the Cochrane Library, PubMed, and Japan Centra Revuo Medicina Web published from 2013 to 2019 and other articles. Articles fulfilling the predefined inclusion criteria were reviewed systematically and their quality was appraised according to the Grading of Recommendations Assessment, Development, and Evaluation system with some modifications. RESULTS: After inclusion and exclusion by full-text review, 29 articles were analyzed. Use of biological disease modifying antirheumatic drugs was a risk factor of SSI (risk ratio 1.66, 95% confidence interval 1.25-2.19), but not of delayed wound healing. RA itself was a risk factor of SSI, and oral glucocorticoid use was a risk factor of SSI in three of the four studies analyzed and of postoperative death. Age, male sex, comorbidities such as diabetes mellitus and chronic obstructive pulmonary disease, surgical factors such as foot/ankle and spine surgery and longer operative time were risk factors of those postoperative complications. CONCLUSION: Patients with those factors should be dealt with appropriate cautions to strike a risk-benefit balance of orthopedic surgeries.

OBJECTIVES: To evaluate the efficacy and safety of tacrolimus in adult patients with rheumatoid arthritis (RA) by using the GRADE approach. METHODS: We searched PubMed, Japana Centra Revuo Medicina Web (Ichu-shi web), and the Cochrane Database of Systematic Reviews. Articles fulfilling the predefined inclusion criteria were appraised and used for meta-analysis. The primary outcomes were American College of Rheumatology 20 (ACR20) and serum creatinine elevation. Other outcomes included ACR50, ACR70, changes in C-reactive protein, modified Health Assessment Questionnaire Disability Index, gastrointestinal disorders, metabolic and nutritional disorders, and infections and infestations. RESULTS: We identified five randomized controlled studies, four of which compared tacrolimus to placebo and were included in the meta-analysis. The risk ratio of ACR20 achievement was 1.71 (95% confidence interval [CI] 1.20-2.42) for 1-2 mg/day and 2.30 (95% CI 1.79-2.96) for 3 mg/day. The risk ratio of creatinine elevation was 1.95 (95% CI 1.18-3.23) for 1-2 mg/day and 3.81 (95% CI 2.43-5.99) for 3 mg/day. CONCLUSION: Tacrolimus is effective with acceptable safety in the management of RA.

BACKGROUND: Axillary lymph nodes (ALNs) are often seen on chest computed tomography (CT) in rheumatoid arthritis (RA) patients. Early reports described lymphadenopathy as one of the systemic manifestations rather than regional lymphadenopathy secondary to drainage from the affected joints. Subsequently, the importance of the immunological events occurring in draining lymph nodes in the development of arthritis was documented. OBJECTIVE: To identify the relationships of local disease activity and background characteristics, including systemic disease activity, systemic disease activity, with axillary lymphadenopathy (AL) in RA using CT. METHODS: RA patients who had undergone chest CT were retrospectively analyzed. The maximum short axis of the ALNs was measured, and the number of positive ALNs ≥ 5 mm was counted. Tender and swollen joints in the upper limbs were counted as indicators of local disease activity. Background characteristics and systemic disease activity were assessed based on the selected RA indicators. Correlations between AL and both local disease activity and background characteristics including systemic disease activity were analyzed. RESULTS: Of 135 patients, 58 had positive ALNs (average size 7.97 mm, range up to 15 mm). The presence of positive unilateral ALNs was correlated with the severity of ipsilateral upper limb arthritis. Multivariate analysis showed correlations between AL and both local disease activity and serological findings such as serum C-reactive protein (CRP) and immunoglobulin (Ig) G. CONCLUSION: AL in patients with RA was correlated with local arthritis activity, as well as background characteristics and systemic disease activity.

OBJECTIVES: To evaluate usage patterns for methotrexate (MTX) and/or glucocorticoids in rheumatoid arthritis (RA) patients receiving biological disease-modifying antirheumatic drugs (bDMARDs) in daily practice. METHODS: Data from RA patients who commenced treatment with bDMARDs (infliximab [IFX], etanercept [ETN], tocilizumab [TCZ], or adalimumab [ADA]) from 2008 to 2010 were extracted from the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) database. The proportions of patients taking concomitant MTX and glucocorticoids and doses of these medications were evaluated before and 2 years after initiation of each bDMARD. RESULTS: A total of 470 RA patients who had initiated a bDMARD (IFX: n = 98, ETN: n = 181, TCZ: n = 90, and ADA: n = 101) were evaluated. The proportion of patients taking MTX decreased over time among ETN and TCZ users, while it increased among ADA users. The MTX dose decreased over time among IFX, ETN, and TCZ users, but not among ADA users. Although the rate of glucocorticoid use and dose decreased after bDMARD initiation in all four bDMARD groups, approximately 50% of patients continued to receive glucocorticoids 2 years after bDMARD initiation. CONCLUSION: MTX and glucocorticoid use and doses in daily practice were commonly reduced after the initiation of bDMARDs, with the dose adjustment varied depending on the bDMARD.

To comprehensively analyze the overall incidence of hospitalization for comorbidities in patients with rheumatoid arthritis (RA). We prospectively analyzed overall hospitalizations for comorbidities using the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort. The incidence of hospitalized comorbidity was calculated. Risk factors for the most frequent hospitalized comorbidities were determined by multivariate logistic regression analysis. Among 5519 RA patients contributing 5336.5 person-years of observation, 435 incidences of hospitalized comorbidity [8.15/100 person-years; 95% confidence interval (CI) 7.40-8.95] were confirmed. The most frequent cause of hospitalized comorbidity was infection (1.52/100 person-years), primarily respiratory system infection (0.77/100 person-years), followed by malignancy (1.03/100 person-years), extra-articular manifestations (0.78/100 person-years), bone fracture (0.77/100 person-years), and acute coronary syndrome (0.22/100 person-years). Death occurred in 0.34/100 person-years (95% CI 0.20-0.53), and in 94.4% of cases the cause of death was the same as that of admission. The risk factors for the most frequent cause of hospitalization, hospitalized infection, were age [odds ratio (OR) 1.03; 95% CI 1.00-1.05], serum albumin level (OR 0.30; 95% CI 0.13-0.69), and corticosteroid use (prednisone > 5 mg/day; OR 3.66; 95% CI 1.81-7.35), but not methotrexate or biological agent use. The present study determined the overall burden of hospitalized comorbidities in patients with RA. These comprehensive data on hospitalized comorbidities may provide a basis for future improvements in the treatment of RA.

The purpose of the study is to demonstrate the characteristics of lymphoproliferative disorders (LPDs) in patients with rheumatoid arthritis (RA) and risk factors for LPD among RA patients concurrently treated with methotrexate (MTX). Among patients who participated in the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort study in October 2010, past existence of LPD from patient's report was confirmed through medical charts. Background factors, LPD pathological findings, and the clinical courses of LPD and RA after LPD were assessed. To analyze the risk of MTX-associated LPD among RA patients concurrently treated with MTX, a nested case-control study design was used to select control patients who had received MTX but did not develop LPD by matching calendar date, sex, and age (within 5 years) at a 1:10 ratio. Odds ratios (ORs) with 95% confidence intervals (95% CIs) for occurrence of LPD were analyzed by multivariate analysis. Forty-eight patients experienced LPD among 5757 patients, and 25 (52.1%) of those had lymphoma. LPD regressed in 60.4% of all LPD patients and 24.0% of lymphoma patients. In the 26 cases who developed LPD during MTX treatment, multivariate analysis revealed that 28-joint disease activity score (DAS28) (OR 1.57 [95% CI, 1.12-1.57]; p < 0.01) and lactate dehydrogenase (LDH) level (OR 1.01 [95% CI, 1.00-1.02]; p < 0.01), but not concomitant dose of MTX, were risk factors for LPD. Among RA patients concomitantly treated with MTX, high disease activity, but not MTX dose, was a risk factor for the occurrence of LPD.

OBJECTIVE: Patients' values and preferences are among the key factors that determine the strength of recommendations presented in clinical practice guidelines (CPG). The aim of this study was to summarize the integration process for patients' perceptions into the development of CPG for rheumatoid arthritis (RA) management in Japan. METHODS: We used a mixed-methods approach. Questionnaires that could be self-administered were mailed to 2222 RA patients randomly selected from the Japan Rheumatism Friendship Association (JRFA) membership list that was age- and prefecture-stratified. A focus group with five JRFA executive members was formed to verify the results of the questionnaire. RESULTS: A total of 1470 patients aged 20-79 years old returned the questionnaire. Analysis of the questionnaire data revealed that the topics selected by the CPG task force met the patients' needs. The focus group participants showed reluctance to use the term 'preference' because patients would not want to take any medications but would have to take them out of necessity. CONCLUSIONS: We confirmed that the new CPG successfully addressed clinical issues that were important to both rheumatologists and patients. Clinicians should understand patients' reluctance to take medications and explain the role of each medication well to increase adherence.

OBJECTIVE: To validate the minimally important difference (MID) of physical function using the Japanese version of the Health Assessment Questionnaire (J-HAQ) in a cohort of rheumatoid arthritis (RA). METHODS: Patients who participated in a cohort study in both October 2008 and April 2009 were analyzed. Patients self-rated their change in overall status over 6 months using a 5-point Likert scale ("much better", "somewhat better", "same", "somewhat worse", or "much worse"). The MID for J-HAQ score was defined as the mean J-HAQ score change in patients who rated themselves "somewhat better". An effect size (ES) of 0.2-0.5 was considered to be suitable for MID. RESULTS: A total of 4560 patients were analyzed. The mean (standard deviation [SD]) MID for J-HAQ score was -0.06 (0.29), corresponding to an ES of 0.08. As exploratory analysis, 1999 patients with a J-HAQ score ≥0.5 and 28-joint disease activity score (DAS28) ≥ 2.6 at baseline were assessed. The mean (SD) MID for J-HAQ score of these patients was 0.13 (0.01), corresponding to an ES of 0.21. CONCLUSIONS: The MID for J-HAQ score was 0.13 in patients with baseline J-HAQ score ≥0.5 and DAS28 ≥ 2.6. The MID for J-HAQ score was influenced by disease status and functional disability.

OBJECTIVE: To evaluate longterm functional outcomes in rheumatoid arthritis (RA) based on the number of times that the American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) or the 28-joint Disease Activity Score (DAS28) remission criteria were fulfilled. METHODS: Patients with RA who participated in all 6 data collections in an observational cohort from 2008 to 2010 and who fulfilled the DAS28 remission criteria at baseline were studied. Patients were classified by the number of times they fulfilled the ACR/EULAR [Boolean trial, Boolean practice, Simplified Disease Activity Index (SDAI), or Clinical Disease Activity Index (CDAI)] or DAS28 remission criteria at each collection. The OR for the Japanese version of the Health Assessment Questionnaire (J-HAQ) progression, based on the number of times each set of remission criteria was fulfilled, were calculated by logistic regression. RESULTS: A total of 915 patients were studied. The OR (95% CI) for J-HAQ progression were 0.54 (0.33-0.87), 0.55 (0.33-0.92), 0.48 (0.28-0.82), 0.29 (0.16-0.51), 0.24 (0.13-0.47), and 0.07 (0.03-0.15) for those fulfilling the Boolean trial remission from 1 to 6 times. This tendency was also observed for the other 4 criteria. The OR (95% CI) for J-HAQ progression in patients who achieved remission at all 6 data collections were 0.07 (0.03-0.14) for the Boolean practice, 0.10 (0.05-0.20) for the SDAI, and 0.07 (0.04-0.15) for the CDAI, whereas 0.15 (0.08-0.29) for the DAS28. CONCLUSION: Continual fulfillment of any remission criteria was strongly effective in preventing patients from progression of functional disability; however, the ACR/EULAR criteria appear to be preferable.

OBJECTIVES: To evaluate the cost-effectiveness of biological disease modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA) in a real-world setting in Japan. METHODS: We used a state-transition model and parameters were determined from RA patients registered in the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) cohort study on 421 patients who had failed at least one DMARD and started either 1 of 4 bDMARDs (bDMARD group; adalimumab, etanercept, infliximab, and tocilizumab) or methotrexate (control group). bDMARD group was evaluated as two groups: sequence of any 1 of 4 bDMARDs with and without tocilizumab. The incremental cost-effectiveness ratios (ICERs) for bDMARD group were estimated using base-case analysis, probabilistic sensitivity analysis (PSA) and scenario sensitivity analyses. RESULTS: ICERs of bDMARD group with or without tocilizumab were $38,179 and $48,855, respectively. By PSA, these sequences had respective probabilities of 86.8% and 75.1% of falling below the assumed cost-effectiveness threshold of $50,000 in Japan. Scenario sensitivity analyses showed that the best population for initiating bDMARD was RA patients less than 50 years old with Japanese version of HAQ between 1.1 and 1.6 and using tocilizumab as the bDMARD. CONCLUSION: bDMARDs were cost-effective for RA patients based on a real-world setting in Japan.

INTRODUCTION: We aimed to identify causes of false-positives in ultrasound scanning of synovial/tenosynovial/bursal inflammation and provide corresponding imaging examples. METHODS: We first performed systematic literature review to identify previously reported causes of false-positives. We next determined causes of false-positives and corresponding example images for educational material through Delphi exercises and discussion by 15 experts who were an instructor and/or a lecturer in the 2013 advanced course for musculoskeletal ultrasound organized by Japan College of Rheumatology Committee for the Standardization of Musculoskeletal Ultrasonography. RESULTS: Systematic literature review identified 11 articles relevant to sonographic false-positives of synovial/tenosynovial inflammation. Based on these studies, 21 candidate causes of false-positives were identified in the consensus meeting. Of these items, 11 achieved a predefined consensus (≥ 80%) in Delphi exercise and were classified as follows: (I) Gray-scale assessment [(A) non-specific synovial findings and (B) normal anatomical structures which can mimic synovial lesions due to either their low echogenicity or anisotropy]; (II) Doppler assessment [(A) Intra-articular normal vessels and (B) reverberation)]. Twenty-four corresponding examples with 49 still and 23 video images also achieved consensus. CONCLUSIONS: Our study provides a set of representative images that can help sonographers to understand false-positives in ultrasound scanning of synovitis and tenosynovitis.

OBJECTIVE: Along with the advances of newly developed medical therapies in rheumatoid arthritis (RA), the number of pharmacoeconomical issues has been paid attention rapidly. For cost-utility analysis and determination of quality-adjusted life years, measurement of the EuroQol 5-dimensional descriptive system (EQ-5D) is essential, and has been used in several clinical studies. However, EQ-5D utility measure in Japanese patients with RA, especially in daily practice has not been fully documented. We analyzed the distribution of EQ5D utility scores and investigated the relationship between other clinical measures based on our Institute of Rheumatology, Rheumatoid Arthritis (IORRA) database. METHOD: Among 5,284 outpatients who participated in the IORRA cohort study on October 2007, data from 5,043 patients who completed the EQ-5D questionnaire were cross-sectionally analyzed. EQ-5D scores in each subgroup for baseline feature such as gender, age, disease activity score 28 (DAS28), and Japanese version of health assessment questionnaire (J-HAQ) were evaluated. For the evaluation of variables that influenced EQ-5D score, the contribution of each variable was evaluated by ANOVA. RESULTS: Average EQ-5D score was 0.76 in 5,284 patients (84% females, average age: 59.0 years, average disease duration: 12.4 years) whose average DAS28 was 3.3 and average J-HAQ was 0.74. EQ-5D scores were highly correlated with J-HAQ and DAS28, and were significantly lower in females and rheumatoid factor-positive patients. Older age, longer disease duration, higher DAS28, and higher J-HAQ were also significantly associated with lower EQ-5D scores. In multivariate analysis, the factor that most strongly influenced EQ-5D was J-HAQ (57.6%), followed by pain visual analog score (VAS; 12.5%). CONCLUSION: This study clearly demonstrated the distribution of EQ-5D score in the daily practice of RA patients, and provides important information for the pharmacoeconomical studies in rheumatology.

OBJECTIVES: To describe the process of collecting and evaluating evidence for treating rheumatoid arthritis (RA) for developing clinical practice guidelines (CPGs) for rheumatologists in Japan. METHODS: The task force comprised rheumatologists, epidemiologists, health economists, and patients. First, the critical outcomes were determined according to a three-round Delphi method, and eight topics with 88 clinical questions (CQs) were formulated. A systematic review of CQs was conducted using the Cochran Database of Systematic Reviews, MEDLINE, and Japana Centra Revvo Medicina (2003-2012). A questionnaire survey and focus group interview were performed to capture the patients' values and preferences. Data from the National Health Insurance drug price list and product information provided by pharmaceutical companies were collected to evaluate drug cost and safety. The GRADE approach was used to describe the evidence quality and determine the strength of recommendations. Recommendations were developed using a modified Delphi method by a multidisciplinary panel including patients. RESULTS: Eight meetings and frequent e-mail communications were conducted to draft a quality assessment of evidence and recommendations. For 88 CQs, recommendation statements were determined. CONCLUSIONS: Using the GRADE approach, new CPGs successfully addressed important clinical issues for treating RA patients. Timely updating of recommendations should be routinely considered.
