Impact of specialty pharmacy collaboration with rheumatology clinics to improve the achievement of treat-to-target goals in patients with rheumatoid arthritis: a pilot study

In rheumatoid arthritis, the use of Routine Assessment of Patient Index Data 3 (RAPID3) assessments to meet treat-to-target goals is endorsed by the 2021 American College of Rheumatology guidelines. In November 2020, the Baylor Scott & White specialty pharmacy implemented a new service that included more frequent collection of RAPID3 scores and standardized provider communication for patients co-managed by a Baylor Scott & White rheumatology clinic. The objective was to evaluate the impact of this new service on rheumatoid arthritis disease activity. Before the new service started, patients followed a protocol of RAPID3 assessments that occurred every 6 months; once the service began, patients were followed using an algorithm in which patients with higher disease activity were contacted more frequently. Eighty-six percent of patients in the pre-intervention group (n = 7) compared with 100% of patients in the post-intervention group (n = 10) had high to moderate disease activity at baseline. Within a 6-month follow-up period in both groups, the percentage of high to moderate disease activity patients decreased by 30% in the post-intervention group and remained the same in the pre-intervention group. These results support the positive impact increased specialty pharmacy services may have on clinical outcomes; therefore, the continued expansion of these services should be considered.

Routine Assessment of Patient Index Data 3 (RAPID3) in Patients with Rheumatoid Arthritis Treated with Long-Term Upadacitinib Therapy in Five Randomized Controlled Trials

Introduction

The Routine Assessment of Patient Index Data 3 (RAPID3) is a patient-reported outcome tool recommended for the assessment of disease activity in patients with rheumatoid arthritis (RA) in clinical practice. This analysis evaluated the long-term effect of upadacitinib vs. comparators on RAPID3 scores in patients with RA in the phase 3 SELECT clinical trial program.

Methods

This post hoc analysis included data from five randomized controlled trials (RCTs) in patients receiving upadacitinib 15 mg or 30 mg once daily (QD) as monotherapy or in combination with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs). The proportions of patients reporting RAPID3 remission (scores ≤ 3) were assessed at week 60. Correlations between absolute scores for RAPID3 and Clinical Disease Activity Index (CDAI), Simplified Disease Activity Index (SDAI), and 28-joint Disease Activity Score with C-reactive protein (DAS28[CRP]) at week 60 were assessed using Spearman correlation coefficients.

Results

A total of 3117 patients were included from the SELECT-NEXT, -BEYOND, -MONOTHERAPY, -COMPARE, and -EARLY trials. By week 60, 32–52% of methotrexate-naïve and csDMARD inadequate responder (IR) patients treated with either upadacitinib 15 mg QD or upadacitinib 30 mg QD reported RAPID3 scores consistent with remission. The proportions were slightly lower in the biologic DMARD-IR SELECT-BEYOND population (19–28%). RAPID3 scores highly correlated (Spearman correlation values ≥ 0.58) with CDAI, SDAI, and DAS28(CRP) scores through week 60 (all p < 0.001).

Conclusions

Upadacitinib, as monotherapy or in combination with csDMARDs, was associated with patient-reported remission assessed by RAPID3 over 60 weeks across the SELECT RCTs in patients with RA.

Rheumatoid arthritis (RA) is a disease that causes inflammation of the joints. Doctors have several ways of assessing how bad a patient’s disease is, and these often use a combination of signs and symptoms to develop a ‘score’. One method is called RAPID3, which is a score based on an overall assessment of the disease by the patient, the level of pain, and the amount of physical disability. An advantage of RAPID3 is that it is quick and easy to use, and since it uses only patient-reported symptoms, it can be measured easily via telemedicine, without the need for an in-person consultation. In this study, we decided to look into the effect of upadacitinib, a drug used for the treatment of RA, on RAPID3 score in patients with RA. We also investigated whether RAPID3 correlates with other ways of measuring RA severity, including scores that use physician-measured factors such as number of affected joints, as this can help show whether RAPID3 is a valid and useful tool. We found that upadacitinib led to long-term improvements in RAPID3 score, and that results were the same in different studies and patient groups, including patients who had not responded well to other treatments. We also found that RAPID3 correlated well with other measures, i.e., improvements in RAPID3 happened in parallel with improvements in other scores. Overall, these results suggest that RAPID3 can be a useful tool in patients with RA.

The RAPID3 questionnaire as a screening tool to reduce the number of outpatient clinic visits: a retrospective cohort study

Background

Treat-to-target strategies require frequent on-site evaluations of disease activity in patients with rheumatoid arthritis (RA), burdening patients and caregivers. However, this frequency may not be required in patients in a stable low disease activity state. The Routine Assessment of Patient Index Data 3 (RAPID3) is a reliable tool to detect such states in groups but has not been tested to reduce the frequency of on-site evaluations in individual patient care. In Reade, an outpatient rheumatology clinic, patients can complete the questionnaire online prior to consultation, and the results are directly fed into the electronic patient record. Focusing on low disease activity, we retrospectively studied the test characteristics of RAPID3 and its agreement with the DAS28 in our database of routine patient care.

Objective

To assess the test characteristics and agreement between de DAS28 and the RAPID3 in patients with RA, with a focus on the low disease activity categories.

Methods

We performed a retrospective database study with available clinical data collected as part of usual care from the electronic medical record at Reade Amsterdam. The dataset comprised RAPID3 assessments followed by a DAS28 within 2 weeks, obtained between June 2014 and March 2021. We dichotomized the disease activity categories for both the RAPID3 and DAS28 into low (remission and low disease activity) and high (moderate and high disease activity). With cutoff values of 2.0 for RAPID3 and 3.2 for DAS28, we calculated test characteristics and agreement (Cohen’s kappa).

Results

A total of 5009 combined RAPID3 and DAS28 measurements were done at Reade in 1681 unique RA patients. The mean age was 60 years, and 76% of patients were female with a median disease duration of 4 years. Agreement was considered fair (kappa = 0.26). In total, 1426 (28%) of the RAPID3 measurements were classified as low and could be potentially targeted to skip their consultations. The sensitivity to detect low disease activity was 0.39, specificity was 0.93, and the positive predictive value was 0.92.

Conclusion

We showed that when the RAPID3 classifies a patient into low disease activity state, the accuracy is 92%. Of all consultations, 28% could possibly be postponed following the screening with RAPID3.

Cross-cultural and clinical validation of the MDHAQ/RAPID3 questionnaire in electronic format for a Brazilian population of patients with rheumatoid arthritis

BACKGROUND

Patients with rheumatologic diseases are monitored fundamentally through metric tools or index calculated from clinical data and patient exams, which allow us to assess the severity of the disease and guide the therapeutic decision. In rheumatoid arthritis (RA), for treatment to be optimized and considered effective, periodic assessment with composite disease activity index and a 'treat-to-target' approach is required. The Routine Assessment of Patient Index Data 3 (RAPID3) in the Multidimensional Health Assessment Questionnaire (MDHAQ) includes only three measures based on the central patient self-reported dataset and can be used in a 'treat-to-target' approach analogous to the Clinical Disease Activity Index (CDAI) and the Disease Activity Score 28-joints (DAS28). This tool, however, has not undergone cross-cultural or clinical validation in Brazil. In this research, we performed the MDHAQ cross-cultural and clinical validation for the Brazilian population of RA patients.

METHODS

The Portuguese version of the MDHAQ was created identically in an electronic questionnaire and underwent a cross-cultural validation process with 38 participants. Test-retest was performed in 29 patients. Further, a clinical validation with 129 Rheumatoid Arthritis patients was performed. Electronic MDHAQ was answered through an online platform. We also collected socioeconomic data as well as other clinical (CDAI, SDAI, DAS28) and functional (HAQ) scores during the face-to-face assessment of patients.

RESULTS

MDHAQ/RAPID3 maintained semantic, idiomatic, as well as conceptual and experience equivalence for the Brazilian population, with 92% acceptance of participants. It showed test-retest reliability, adequate internal consistency (Cronbach's α 0.85) and correlation of the scores obtained with adequate association with the DAS28 gold standard. RAPID3 also had high sensitivity (98%), adequate specificity (48%), high negative predictive value (92%) and negative post-test probability of 8%, attributes expected for a test tool for population screening.

CONCLUSION

The use of MDHAQ/RAPID3 associated with traditional clinical measures can adequately allow for remote follow-up based on the 'treat-to-target' approach with performance comparable to the gold standard DAS28, being a viable tool in the sample of Brazilian patients with RA in the current context of telehealth.

Empirical evidence of disease activity thresholds used to indicate need for major therapeutic change in US veterans with rheumatoid arthritis

Background

A previous analysis of the Veterans Affairs Rheumatoid Arthritis (VARA) registry showed that more than half of the patients with rheumatoid arthritis (RA) did not receive a major therapeutic change (MTC) despite moderate or severe disease activity. We aimed to empirically determine disease activity thresholds associated with a decision by rheumatologists and nurse practitioners to institute a MTC in patients with RA and to report the impact of that change on RA disease activity.

Methods

We analyzed data from the VARA registry between January 1, 2006, and September 30, 2017. Eligible patients had a visit with 3 disease activity measures (DAMs) recorded: Disease Activity Score for 28 joints (DAS28), Clinical Disease Activity Index (CDAI), and Routine Assessment of Patient Index Data 3 (RAPID3). The Youden Index was used to identify disease activity thresholds that best discriminated rheumatologist/nurse practitioner decision to initiate MTC. Clinical outcome was 20% improvement in the American College of Rheumatology criteria (ACR20 response). The effect of MTC on ACR20 response was presented as crude descriptive statistics and evaluated using G-computation for marginal and conditional effects with established disease activity level combined with an empirical threshold from Youden analysis.

Results

The study population comprised 1776 patients (12,094 visits: 3077 with MTC, 9017 without MTC). Empirical thresholds (95% bootstrap confidence interval with 1000 replications) for MTC were 4.03 (3.70–4.36) for DAS28, 12.9 (10.4–15.4) for CDAI, and 3.81 (3.32–4.30) for RAPID3. Visits with MTC had increased likelihood of ACR20 response: risk ratios for ACR20 response for visits with MTC vs without MTC ranged 1.2–2.6 across DAMs; risk differences ranged 0.2–14.5%.

Conclusions

MTC was associated with clinical improvement across all DAMs with the greatest change in patients with RA disease activity above the Youden threshold identified in this work.

Disease activity measures at baseline predict structural damage progression: data from the randomized, controlled AMPLE and AVERT trials

Objective

Data from two double-blind, randomized, Phase III studies were analysed to investigate the ability of Routine Assessment of Patient Index Data 3, DAS28 (CRP), modified (M)-DAS28 (CRP) and Simplified or Clinical Disease Activity Indices to predict structural damage progression in RA.

Methods

This post hoc analysis included data from the 2-year Abatacept vs adaliMumab comParison in bioLogic-naïvE RA subjects with background MTX (AMPLE) trial in biologic-naïve patients with active RA (<5 years) and an inadequate response to MTX, and the 12-month treatment period of the Assessing Very Early Rheumatoid arthritis Treatment (AVERT) trial in MTX-naïve patients with early RA (⩽2 years) and poor prognostic indicators. Adjusted logistic regression analysis assessed the relationship between baseline disease activity and structural damage progression (defined as change from baseline greater than the smallest detectable change) at 12 and 24 months in AMPLE and 6 and 12 months in AVERT. Areas under the receiver operating characteristic curves for the impact of baseline disease activity on structural damage progression were calculated.

Results

Adjusted logistic regression analyses included all randomized and treated patients in AMPLE (N = 646) and those who received abatacept plus MTX or MTX monotherapy in AVERT (N = 235). Baseline Routine Assessment of Patient Index Data 3, DAS28 (CRP) and M-DAS28 (CRP) scores significantly predicted structural progression at months 12 and 24 in AMPLE (P < 0.05) and months 6 and 12 in AVERT (P < 0.01), and were stronger predictors than Simplified or Clinical Disease Activity Indices.

Conclusion

In this post hoc analysis of two patient populations with RA, Routine Assessment of Patient Index Data 3, DAS28 (CRP) and M-DAS28 (CRP) were good at predicting structural damage.

Measurement properties of instruments assessing psoriatic arthritis symptoms for psoriasis clinical trials: a systematic literature review

Introduction: The International Dermatology Outcome Measures (IDEOM) identified 'Psoriatic Arthritis (PsA) Symptoms' as a core domain to be measured in psoriasis clinical trials. This domain includes the measurement of pain, patient global and physical function. Herein, we evaluated the quality (i.e. measurement properties) of five candidate 'PsA Symptoms' measures: Patient Global Assessment (PGA) for Joints, PGA for PsA, the Routine Assessment Patient Index 3 (RAPID3), the PsA Impact of Disease 9 (PsAID9) and PsAID12.Areas covered: We searched MEDLINE and EMBASE (inception-to-March 2018) for studies assessing the measurement properties of candidate instruments. Two reviewers independently assessed the risk of bias of 12 eligible articles using the COSMIN checklist. For each measurement property, we rated the quality of the evidence as 'high,' 'moderate,' 'low,' or 'very low' (GRADE approach) and classified the results as 'sufficient,' 'insufficient,' or 'inconsistent.' Finally, we provided recommendations.Expert opinion: In PsA, RAPID3 had 'very low' quality evidence for 'sufficient' content validity and no evidence of internal structure. Global assessment instruments had 'very low' quality evidence for 'inconsistent' content validity. PsAID9 and PsAID12 had 'low' evidence for 'sufficient' content validity and were recommended to measure 'PsA Symptoms.' Further validation studies will improve the level of evidence of this recommendation.

Barriers to treatment optimization and achievement of patients' goals: perspectives from people living with rheumatoid arthritis enrolled in the ArthritisPower registry

BACKGROUND

Few studies have investigated patients' own treatment goals in rheumatoid arthritis (RA). The objective of this real-world, cross-sectional study of US patients with RA was to identify factors that patients believed influenced their physician's treatment decisions. Secondary objectives included reasons patients tolerated sub-optimal disease control and their perceived barriers to treatment optimization.

METHODS

Eligible participants were enrolled in the ArthritisPower registry, ≥ 19 years, had physician-diagnosed RA, unchanged treatment within 3 months of baseline, prior/current disease-modifying antirheumatic drug treatment (DMARDs), and computer/smartphone access. In December 2017, participants completed Patient-Reported Outcomes Measurement Information System-Computerized Adaptive Tests (PROMIS-CAT) for pain interference, fatigue, sleep disturbance, and physical function. Routine Assessment of Patient Index Data 3 (RAPID3) provided disease activity scores (0-30). Participants completed an online survey on barriers to treatment optimization, including self-perception of disease compared to RAPID3/PROMIS scores.

RESULTS

A total of 249 participants met inclusion criteria and completed the survey. Mean age (SD) was 52 (11) years, and the majority were female (92%) with high RAPID3 disease activity (175/249 [70%]; median score 18). The main reason participants did not change treatment was their physician's recommendation (66%; n = 32). Of participants with high RAPID3 disease activity, 66 (38%) were offered a treatment change; 19 (29%) of whom declined the change. Most participants who intensified treatment did so because their symptoms had remained severe or worsened (51%; n = 65); only 16 (25%) participants intensified because they had not reached a specified treatment goal. Among participants who self-reported their disease activity as "none/low" or "medium" (n = 202; 81% of cohort), most still had RAPID3 high disease activity (137/202 [68%]; score > 12). Most PROMIS scores showed moderate agreement with participants' self-assessment of health status, in contrast to RAPID3 (weighted kappa: 0.05 [95% CI - 0.01, 0.11]).

CONCLUSIONS

Most participants trusted their rheumatologist's treatment decisions and prioritized their physician's treatment goals over their own. Patients should be encouraged to share their treatment goals/expectations with their rheumatologist, in line with the treat-to-target approach. RAPID3 may be inappropriate for setting patient-centric treatment goals given the poor agreement with self-reported disease activity; most PROMIS scores showed better alignment with patients' own assessments.

Routine Assessment of Patient Index Data 3 (RAPID3) alone is insufficient to monitor disease activity in rheumatoid arthritis in clinical practice

Objective

To test the longitudinal association between patient-reported outcome, Routine Assessment of Patient Index Data 3 (RAPID3) and the Disease Activity Score in 28 joints that includes the erythrocyte sedimentation rate (DAS28-ESR) in routine-care patients with rheumatoid arthritis (RA).

Methods

Patients with RA treated with disease-modifying antirheumatic drugs were included in this prospective observational cohort. The longitudinal association between RAPID3 (0-10) and DAS28-ESR and its individual components (swollen joint count (SJC), erythrocyte sedimentation rate (ESR) (mm/hour), tender joint count (TJC) and patient global assessment (PGA)) was tested using generalised estimating equations in patients with more than two consecutive visits with data on RAPID3 and DAS28-ESR. Interactions between RAPID3 and gender, pain, PGA and age at baseline were tested, and if significant (p<0.20) and clinically relevant, models were fit in the corresponding strata.

Results

In total, 330 patients were included (mean follow-up 10.7 (SD 9.7) months, female gender 67.9%). The longitudinal association between RAPID3 and DAS28-ESR was weak (β=0.29 (95% CI 0.24 to 0.35), n=207), meaning that one unit increase in RAPID3 corresponded to a 0.29 unit increase in Disease Activity Score in 28 joints (DAS28). RAPID3 was most strongly associated with subjective (TJC: β=0.89 (95% CI 0.61 to 1.17); PGA: β=0.94 (95% CI 0.84 to 1.04)) and not with objective components of DAS28 (SJC: β=0.29 (95% CI 0.17 to 0.41), n=172). The association between RAPID3 and ESR was poor but modified by gender, being only significant in men (β=0.37 (95% CI 0.08 to 0.67)).

Conclusions

These data suggest that RAPID3 does not sufficiently capture changes in objective inflammatory signs. Monitoring by RAPID3 alone is therefore insufficient to follow disease activity in patients wth RA in clinical practice.

Evaluation of disease activity in patients with rheumatoid arthritis treated with tofacitinib by RAPID3: post hoc analyses from two phase 3 trials

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis. We evaluated the relationship between disease activity, according to Routine Assessment of Patient Index Data 3 (RAPID3) after 6-month treatment with tofacitinib, and long-term outcomes at 24 months. This was a post hoc analysis of two 24-month, phase 3, randomized controlled trials in methotrexate (MTX)-naïve (ORAL Start [NCT01039688]) or MTX-inadequate responder patients (ORAL Scan [NCT00847613]) receiving tofacitinib 5 or 10 mg twice daily (BID) as monotherapy or with background MTX. RAPID3 scores were calculated at baseline, month (M)6, and M24, and defined as remission (≤ 3), low (LDA; > 3-≤ 6), moderate (MDA; > 6-≤ 12), or high disease activity (HDA; > 12). Clinical Disease Activity Index (CDAI), Health Assessment Questionnaire-Disability Index (HAQ-DI) scores, and radiographic non-progression (modified Total Sharp Scores ≤ 0) at M24 were evaluated by M6 RAPID3 response. Among patients receiving tofacitinib 5 or 10 mg BID, respectively, 42.2 and 51.5% (ORAL Start) and 29.8 and 39.0% (ORAL Scan) achieved RAPID3 remission/LDA at M6. Most patients maintained/improved RAPID3 responses at M24. A higher proportion of patients in RAPID3 remission/LDA versus MDA/HDA at M6 achieved CDAI remission, reported normative HAQ-DI scores (< 0.5), and achieved both normative HAQ-DI scores and radiographic non-progression at M24. Patients achieving RAPID3 remission/LDA after 6-month treatment with tofacitinib 5 or 10 mg BID have improved long-term outcomes versus patients with MDA/HDA. These findings support the use of RAPID3 to monitor longer-term disease activity in conjunction with physician-assessed measures.

Securely collecting multidimensional health information from patients with rheumatoid arthritis using smart device technology: Beneficial effect for physicians and patients

AIM

A challenge to the medical care of patients with rheumatoid arthritis (RA) is the management of the wide variety of information, including medication history and disease status, obtained from multiple sources to inform treatment decisions. To address this important clinical issue, we developed a data management system, based on smart device technology, and evaluated the benefit of this information to medical experts in helping them to form an impression of patients' health and disease, and treatment status before examination.

METHODS

Fifty-seven patients with RA input relevant information about their condition and responses to a self-report health assessment questionnaire into a smart device template before their scheduled examination. The efficacy of the system was assessed as a decrease in examination time at each visit, and the correlation between the self-reported Multi-Dimensional Health Assessment Questionnaire and the 28-joint Disease Activity Score 28-joint count erythrocyte sedimentation rate (DAS28-ESR), which was used as a gold standard.

RESULTS

Examination duration was reduced in most patients at each visit. During the study, there were no limitations for patients with poor eyesight or severe arthropathy in using the system. In fact, the majority of patients found the smart technology to be easier to use than hand-written questionnaires and health forms, regardless of age and disease activity.

CONCLUSIONS

Our findings support the use of smart technology to provide accurate patient-specific data and to streamline the process of medical care for patients with RA.

Comparison of composite indices with global synovitis score on ultrasound for detecting remission

We aimed to compare composite indices with Ultrasound Global Synovitis Score (GLOESS) for remission in rheumatoid arthritis (RA). RA patients in remission according to the clinician were investigated with Disease Activity Score28 (DAS28), Clinical Disease Activity Index (CDAI), Simplified Disease Activity Index (SDAI), and RAPID-3 (Routine Assessment of Patient Index Data 3). Ultrasonography was performed using the GLOESS scores. Patients in CDAI-remission had lower GLOESS (median (IQR), 5(3-9.75) vs 7(4-11.75), p = 0.048) with a similar trend in SDAI (5(3-9.25) vs 7(4-11.25), p = 0.064). This was not observed with DAS28-CRP and RAPID3. Our results show that CDAI is superior to other indices to assess remission in RA.

A somatization comorbidity phenotype impacts response to therapy in rheumatoid arthritis: post-hoc results from the certolizumab pegol phase 4 PREDICT trial

Background

Comorbidities may contribute to disease activity and treatment response in rheumatoid arthritis (RA) patients. We defined a somatization comorbidity phenotype (SCP) and examined its influence on response to certolizumab pegol (CZP) using data from the PREDICT trial.

Methods

Patients in PREDICT were randomized to the patient-reported Routine Assessment of Patient Index Data 3 (RAPID3) or physician-based Clinical Disease Activity Index (CDAI) for treatment response assessment. Post-hoc analyses identified patients with the SCP, which included diagnosis of depression, fibromyalgia/myalgias, and/or use of medications indicated for treatment of depression, anxiety, or neuropathic pain. The effect of the SCP on RAPID3 or CDAI response at week 12 and low disease activity (LDA; Disease Activity Score in 28 joints based on erythrocyte sedimentation rate ≤ 3.2) at week 52, in week-12 responders, was analyzed using non-parametric analysis of covariance (ANCOVA).

Results

At baseline, 43% (313/733) of patients met the SCP classification. Patients with the SCP were 9% more likely to withdraw from the trial. American College of Rheumatology 20% (ACR20), ACR50, and ACR70 responses were 5–14% lower among those with the SCP, and 11% more patients reported adverse events (AEs). Patients without SCP in the CDAI arm were twice as likely to achieve LDA at week 52 compared with those with SCP (32% versus 16%). No differentiation by SCP was observed in the RAPID3 arm (pooled result 21.5%).

Conclusions

We operationalized a potentially important somatization comorbidity phenotype in a trial setting that was associated with a substantially lower likelihood of treatment response and a higher frequency of AEs. Including large numbers of patients with this phenotype in RA trials may reduce the measured clinical effectiveness of a new molecule.

Pragmatic assessment of exercise in routine care using an MDHAQ: associations with changes in RAPID3 and other clinical variables

Background

Exercise is associated with major benefits in patients with rheumatic diseases for both cardiovascular and rheumatic status. However, information about exercise generally is not collected systematically in routine rheumatology care. A multidimensional health assessment questionnaire (MDHAQ), which was designed for busy clinical settings, includes a query about exercise status. We analyzed possible associations between change in MDHAQ exercise scores and other MDHAQ measures in patients with various rheumatic diseases over one year.

Methods

In one rheumatology clinical setting, all patients, regardless of diagnosis, complete an MDHAQ before seeing a rheumatologist. The MDHAQ includes scores for physical function, pain, and patient global estimate, compiled into an index, routine assessment of patient index data (RAPID3), as well as a self-report joint count and a query about exercise. Patients were classified into four groups according to their exercise status at baseline and one year later as: EXER-Yes (regular exercise), EXER-Yes; EXER-No (no regular exercise), EXER-Yes; EXER-Yes, EXER-No; and EXER-No, EXER-No. These groups were compared using the chi square and Kruskal-Wallis tests and analysis of variance (ANOVA).

Results

Patients who reported regular exercise at baseline were younger, had higher formal education, and better clinical status than other patients. The EXER-No, EXER-Yes group had greater improvement in other MDHAQ variables than patients in the other three groups. By contrast, the EXER-Yes, EXER-No group was the only group with poorer status one year later.

Conclusions

The MDHAQ exercise query indicates that regular exercise is associated with better clinical status. Patients in the EXER-No, EXER-Yes group reported the best clinical improvement, although it is not known whether exercise preceded or followed the improved clinical status.

One-year maintenance with routine assessment of patient index data 3-based remission may inhibit radiographic progression in patients with rheumatoid arthritis treated with routine clinical therapy: A retrospective comparison of radiographic outcome and its prognostic factors between maintained remissions with patient-reported outcome index and physician-oriented disease activity indices

OBJECTIVES

We investigated whether the maintenance of routine assessment of patient index data 3 (RAPID3) remission for one year (RAPID3-MR) may predict good radiographic outcomes. We also compared radiographic progression to prognostic factors among patients with RAPID3-MR, with the maintenance of clinical disease activity index remission for one year (CDAI-MR) or with the maintenance of 28 joint count disease activity score remission for one year (DAS28-MR).

METHODS

Of 1220 patients with available clinical data, 92 with RAPID3-MR, 80 with RAPID3-NMR (not satisfying RAPID3-MR), 45 with CDAI-MR, and 75 with DAS28-MR were retrospectively investigated. CDAI and DAS28 for clinical outcomes and the modified total Sharp score (mTSS) for radiographic joint damage were investigated for at least one year.

RESULTS

RAPID3, CDAI, DAS28, and their categories remained unchanged or significantly improved in RAPID3-MR patients but significantly deteriorated in RAPID3-NMR patients. The mean annual ΔmTSS was significantly lower in RAPID3-MR patients (0.12 ± 0.55) than in RAPID3-NMR patients (0.54 ± 1.27) (p = 0.025). There was no significant difference among RAPID3-MR patients, CDAI-MR patients (0.06 ± 0.85), and DAS28-MR patients (0.11 ± 0.89). The baseline mTSS (p = 0.038) and monotherapy with nonbiological disease-modifying antirheumatic drugs (p = 0.033) were good prognostic factors in RAPID3-MR patients.

CONCLUSIONS

One-year RAPID3 remission maintenance may predict good radiographic outcomes.

Multibiomarker disease activity score and C-reactive protein in a cross-sectional observational study of patients with rheumatoid arthritis with and without concomitant fibromyalgia

OBJECTIVES

To examine the association between a multibiomarker disease activity (MBDA) score, CRP and clinical disease activity measures among RA patients with and without concomitant FM.

METHODS

In an observational cohort of patients with established RA, we performed a cross-sectional analysis comparing MBDA scores with CRP by rank correlation and cross-classification. MBDA scores, CRP and clinical measures of disease activity were compared between patients with RA alone and RA with concomitant FM (RA and FM) by univariate and multivariate analyses.

RESULTS

CRP was ⩽1.0 mg/dl for 184 of 198 patients (93%). MBDA scores correlated with CRP (r = 0.755, P < 0.001), but were often discordant, being moderate or high for 19%, 55% and 87% of patients with CRP ⩽0.1, 0.1 to ⩽0.3, or 0.3 to ⩽1.0 mg/dl, respectively. Among patients with CRP ⩽1.0 mg/dl, swollen joint count (SJC) increased linearly across levels of MBDA score, both with (P = 0.021) and without (P = 0.004) adjustment for CRP, whereas CRP was not associated with SJC. The 28-joint-DAS-CRP, other composite measures, and their non-joint-count component measures were significantly greater for patients with RA and FM (n = 25) versus RA alone (n = 173) (all P ⩽ 0.005). MBDA scores and CRP were similar between groups.

CONCLUSION

MBDA scores frequently indicated RA disease activity when CRP did not. Neither one was significantly greater among patients with RA and FM versus RA alone. Thus, MBDA score may be a useful objective measure for identifying RA patients with active inflammation when CRP is low (⩽1.0 mg/dl), including RA patients with concomitant FM.

Patient-reported outcomes in ANCA-associated vasculitis. A comparison between Birmingham Vasculitis Activity Score and routine assessment of patient index data 3

The objective of this study was to determine health-related quality of life (HRQoL) in patients with ANCA-associated vasculitis (AAV) as measured by the "routine assessment of patient index data 3" (RAPID3) and whether RAPID3 is correlated with disease activity as determined by the Birmingham Vasculitis Activity Score (BVAS). Data from patients at an academic institution vasculitis clinic seen between Jan 2010 and Jan 2012 were collected using chart review. BVAS and RAPID3 scores were calculated at each patient visit. RAPID3 was compared between patients in remission (BVAS = 0) and patients with active disease (BVAS > =1) at all visits for four consecutive visits, when data available, at least 3 months apart during the period mentioned. Robust generalized estimating equations (GEE) in linear regression models evaluated associations between the RAPID3 and BVAS over all available observations, adjusting for intra-subject correlations. Thirty-four patients were included in the study, 26 had granulomatosis with polyangiitis (GPA), five microscopic polyangiitis (MPA), and three eosinophilic granulomatosis with polyangiitis (EGPA). Patients at first visit had impaired HRQoL as measured by RAPID3 [6.8 (3.1-12.6)]. The median RAPID3 scores were higher in patients with active disease as compared to patients in remission (7.0 vs. 3.0, p = 0.115; 8.8 vs. 1.0, p = 0.011; 6.1 vs. 2.0, p = 0.032; and 11.7 vs. 2.0, p = 0.128 for visits 1, 2, 3, and 4, respectively). In longitudinal GEE models incorporating all observations there was a strong association between the RAPID3 (per 1 unit) and BVAS (per 1 unit) [β 0.21 (0.10, 0.32) p < 0.001]. RAPID3 can be used to measure HRQoL in patients with AAV. RAPID3 correlated significantly with BVAS. RAPID3 can discriminate between disease states in AAV. This instrument may help document patient experience and add to clinical decisions.

Validation of RAPID3 using a Japanese version of Multidimensional Health Assessment Questionnaire with Japanese rheumatoid arthritis patients: characteristics of RAPID3 compared to DAS28 and CDAI

OBJECTIVES

To validate Routine Assessment of Patient Index Data 3 (RAPID3) using a Japanese version of Multidimensional Health Assessment Questionnaire (MDHAQ) with Japanese rheumatoid arthritis (RA) patients and to describe the characteristics of RAPID3 by comparison with Disease Activity Score 28 (DAS28) and Clinical Disease Activity Index (CDAI).

METHODS

The original MDHAQ was translated into Japanese with minor cultural modifications and was translated back in English. Test-retest reliability was evaluated in 50 Japanese RA patients and further validation was performed in 350 Japanese RA patients recruited by seven rheumatologists. RAPID3, CDAI, and DAS28 were assessed on two consecutive visits.

RESULTS

The test-retest reliability and the internal reliability of RAPID3 were excellent. Spearman's correlation coefficients between RAPID3 score versus CDAI score and DAS28 score were 0.761and 0.555. However, the agreement measured by kappa (weighted) for RAPID3 category versus CDAI category and for RAPID3 category versus DA28 category were 0.225 (0.382) and 0.187 (0.336). The sensitivity and specificity of "RAPID3 ≤ 3 and swollen joint ≤ 1" for predicting Boolean remission were 90.0% and 93.4%, respectively.

CONCLUSIONS

RAPID3 obtained by Japanese MDHAQ was validated with Japanese RA patients and the remission criteria were found to have excellent clinical utility in usual care.
