Quantitative Data for Care of Patients with Systemic Lupus Erythematosus in Usual Clinical Settings: A Patient Multidimensional Health Assessment Questionnaire and Physician Estimate of Noninflammatory Symptoms

Evaluating the real-world effectiveness of belimumab in patients with SLE using SLE-related laboratory values and rheumatoid arthritis-derived disease activity measures: RAPID3, swollen joint count and tender joint count

OBJECTIVE

To investigate the real-world impact of intravenous belimumab treatment among patients with SLE using rheumatoid arthritis-derived disease activity measures and SLE-related laboratory values.

METHODS

This retrospective cohort study used US electronic medical record data from the United Rheumatology Normalised Integrated Community Evidence (UR-NICE) database. Adult patients with SLE who initiated intravenous belimumab between 1 January 2012 and 3 December 2019 (index), had 12 months of pre-index and 24 months of post-index clinical activity, and had ≥6 infusions of belimumab during the 24 months post-index were included. The primary outcome measure was time to first improvement of minimally important difference (MID) for Routine Assessment of Patient Index Data 3 (RAPID3), Patient Pain Index (PPI), swollen joint count, tender joint count (TJC), complement C3 and C4 and anti-double-stranded DNA antibodies during the on-treatment follow-up period of up to 24 months. The secondary outcome measure evaluated the trajectories of these outcome measures for up to 24 months of belimumab treatment.

RESULTS

Of 495 patients included, between 21.0% and 52.1% had ≥1 record for each of the disease activity measures or laboratory values in the pre-index and post-index periods and were included in analyses for that measure. The proportion of patients achieving MID for each measure increased rapidly within 3 months, with continued gradual improvement throughout the remaining on-treatment period, up to 24 months. After 6 months, 52.3% and 55.3% of patients had achieved MID in RAPID3 and PPI, respectively. Outcome measure trajectories indicated improved disease activity with belimumab treatment, particularly in RAPID3, TJC and laboratory values.

CONCLUSIONS

In this real-world effectiveness study, belimumab therapy for SLE resulted in clinically meaningful improvements in rheumatoid arthritis-derived disease activity measures within 3 months of treatment, with patients who remained on belimumab therapy experiencing improvement even up to 24 months of observation.

Medication Cost Concerns and Disparities in Patient-Reported Outcomes Among a Multiethnic Cohort of Patients With Systemic Lupus Erythematosus

OBJECTIVE

Concerns about the affordability of medications are common in systemic lupus erythematosus (SLE), but the relationship between medication cost concerns and health outcomes is poorly understood. We assessed the association of self-reported medication cost concerns and patient-reported outcomes (PROs) in a multiethnic SLE cohort.

METHODS

The California Lupus Epidemiology Study is a cohort of individuals with physician-confirmed SLE. Medication cost concerns were defined as having difficulties affording SLE medications, skipping doses, delaying refills, requesting lower-cost alternatives, purchasing medications outside the United States, or applying for patient assistance programs. Linear regression and mixed effects models assessed the cross-sectional and longitudinal association of medication cost concerns and PROs, respectively, adjusting for age, sex, race and ethnicity, income, principal insurance, immunomodulatory medications, and organ damage.

RESULTS

Of 334 participants, medication cost concerns were reported by 91 (27%). Medication cost concerns were associated with worse Systemic Lupus Activity Questionnaire (SLAQ; beta coefficient [β] 5.9, 95% CI 4.3-7.6; P < 0.001), 8-item Patient Health Questionnaire depression scale (PHQ-8; β 2.7, 95% CI 1.4-4.0; P < 0.001), and Patient-Reported Outcomes Measurement Information System (PROMIS; β for physical function -4.6, 95% CI -6.7 to -2.4; P < 0.001) scores after adjusting for covariates. Medication cost concerns were not associated with significant changes in PROs over 2-year follow-up.

CONCLUSION

More than a quarter of participants reported at least 1 medication cost concern, which was associated with worse PROs. Our results reveal a potentially modifiable risk factor for poor outcomes rooted in the unaffordability of SLE care.

Evaluation of the LFA-REAL clinician-reported outcome (ClinRO) and patient-reported outcome (PRO): prespecified analysis of the phase III ustekinumab trial in patients with SLE

OBJECTIVE

The Lupus Foundation of America Rapid Evaluation of Activity in Lupus (LFA-REAL) system is a novel and simple SLE disease activity instrument, consisting of a tandem clinician-reported (ClinRO) and patient-reported (PRO) outcome measure. The aim of this study was to compare the LFA-REAL system with other SLE activity measures in the phase III trial of ustekinumab in patients with active SLE.

METHODS

This was a prespecified analysis of data from a randomised, double-blind, placebo-controlled, parallel-group trial conducted at 140 sites in 20 countries. Correlations were evaluated between the LFA-REAL ClinRO and PRO with a panel of clinician-reported and patient-reported disease activity measures commonly used in SLE clinical trials at baseline, week 24 and week 52. All p values are reported as nominal.

RESULTS

Trial participants included 516 patients with SLE with a mean (SD) age of 43.5 (8.9), of whom 482 (93.4%) were female. The LFA-REAL ClinRO correlated with Physician Global Assessment (r=0.39, 0.65 and 0.74, p<0.001), British Isles Lupus Assessment Group Index (r=0.43, 0.67 and 0.73, p<0.001) and SLE Disease Activity Index-2000 (r=0.35, 0.60 and 0.62, p<0.001). The LFA-REAL ClinRO arthralgia/arthritis score correlated well with active joint counts (r=0.54, 0.73 and 0.68, p<0.001) and the mucocutaneous global score correlated strongly with Cutaneous Lupus Erythematosus Disease Area and Severity Index total activity (r=0.57, 0.77 and 0.81, p<0.001). The LFA-REAL PRO demonstrated a moderate correlation with Functional Assessment of Chronic Illness Therapy-Fatigue (r=-0.60, -0.55 and -0.58, p<0.001), Lupus QoL physical health (r=-0.42, -0.47 and -0.46, p<0.001), SF-36v2 vitality (r=-0.40, -0.43 and -0.58, p<0.001) and SF-36v2 Physical Component Summary (r=-0.45, -0.53 and -0.53, p<0.001). The LFA-REAL ClinRO and PRO showed a moderate correlation with each other (r=0.32, 0.45 and 0.50, p<0.001).

CONCLUSIONS

The LFA-REAL ClinRO and PRO showed varied levels of correlations (weak to strong) with existing physician-based lupus disease activity measures and patient-reported outcome instruments, respectively and were able to more accurately capture organ-specific mucocutaneous and musculoskeletal manifestations. More analyses are needed to determine areas in which patient-reported outcomes are most similar or different to physician-reported end points and the basis for differences.

A 5-Year Retrospective, Observational Study Assessing Rheumatoid Arthritis Disease Outcome Measures to Characterize Systemic Lupus Erythematosus Burden in the USA

INTRODUCTION

We evaluated the use of rheumatoid arthritis (RA) disease measures in patients with systemic lupus erythematosus (SLE) in a US community-based rheumatology physician network over 5 years.

METHODS

This retrospective, observational cohort study (GSK Study 213818) of patients with SLE utilized electronic medical records (01 January 2010-31 December 2019) from the United Rheumatology Normalized Integrated Community Evidence database. The index was the date of first SLE diagnosis recorded in the database; the observation period was 5 years post-index. RA disease measures evaluated were: Pain Index, Multi-Dimensional Health Assessment Questionnaire (MD-HAQ), Patient Global Assessment (PtGA), Physician Global Assessment (PGA), Swollen Joint Count (SJC), Tender Joint Count (TJC), Routine Assessment of Patient Index Data 3 (RAPID3), Clinical Disease Activity Index (CDAI), Simplified Disease Activity Index (SDAI), and Disease Activity Score 28 (DAS-28). The number of patients with measures utilized, the score on each measure, and proportion of patients per disease activity category were assessed.

RESULTS

Overall, 5990 patients with SLE were included. The most frequently used measures were Pain Index, SJC, TJC, MD-HAQ, PtGA, RAPID3, and PGA (cumulative use over Years 1-5: 23.9-71.3%). For all measures, frequency of use was lowest in Year 1, followed by a general increase from Year 1 to Year 5. Scores remained relatively stable for most measures, and the proportion of patients in remission or with low/moderate disease activity per RAPID3 increased.

CONCLUSION

RA disease measure utilization in SLE was generally infrequent but increased over time. Pain Index and MD-HAQ were the most commonly applied cumulatively across 5 years of follow-up. The rationale for the increased use of these measures in SLE over time requires further exploration. In the absence of a clinically applicable SLE-specific measure, the use of RA measures, for example in conjunction with SLE measures, may provide an alternative approach for measuring disease activity, representing an opportunity to improve patient outcomes.

Evaluation of the LFA-REAL clinician-reported outcome (ClinRO) and patient-reported outcome (PRO): data from the Peruvian Almenara Lupus Cohort

OBJECTIVE

The Lupus Foundation of America Rapid Evaluation of Activity in Lupus (LFA-REAL) clinician-reported outcome (ClinRO) and the LFA-REAL patient-reported outcome (PRO) were developed in order to capture manifestations of SLE from the perspective of both the clinician and the patient. The aim of this study is to compare the LFA-REAL ClinRO and PRO with other lupus disease activity measures.

METHODS

A cross-sectional analysis of patients from a single-centre cohort was performed using Spearman's correlation. Disease activity measures included were LFA-REAL ClinRO (range 0-1400), LFA-REAL PRO (range 0-1200), Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K), clinical SLEDAI-2K and Physician Global Assessment (PGA, range 0-100).

RESULTS

Two hundred and twenty-seven patients with SLE were studied. The mean age was 46.3 (SD: 13.8); 212 (93.4%) were female. The mean (SD) LFA-REAL ClinRO was 25.4 (34.7), LFA-REAL PRO was 241.1 (187.6), PGA was 11.9 (15.4), SLEDAI-2K was 2.3 (3.3) and clinical SLEDAI-2K was 1.6 (2.9). The LFA-REAL ClinRO correlated with PGA (r=0.758, p<0.001), SLEDAI-2K (r=0.608, p<0.001) and clinical SLEDAI-2K (r=0.697, p<0.001); the LFA-REAL PRO correlated modestly with PGA (r=0.160, p=0.016), SLEDAI-2K (r=0.121, p=0.069), clinical SLEDAI-2K (r=0.143, p=0.031) and LFA-REAL ClinRO (r=0.161, p=0.015).

CONCLUSIONS

The LFA-REAL ClinRO and the LFA-REAL PRO had good and weak correlations, respectively, with several physician-based disease activity measures in a cross-sectional study, suggesting their potential usefulness in establishing disease severity. Longitudinal studies will be required to determine their value in monitoring patients with SLE.

Patient-Reported Outcomes for Quality of Life in SLE: Essential in Clinical Trials and Ready for Routine Care

Patient-reported outcome (PRO) instruments are widely used to assess quality of life in Systemic Lupus Erythematosus (SLE) research, and there is growing evidence for their use in clinical care. In this review, we evaluate the current evidence for their use in assessing quality of life in SLE in both research and clinical settings and examine the different characteristics of the commonly used PRO tools. There are now several well-validated generic and SLE-specific tools that have demonstrated utility in clinical trials and several tools that complement activity and damage measures in the clinical setting. PRO tools may help overcome physician–patient discordance in SLE and are valuable in the assessment of fibromyalgia and type 2 symptoms such as widespread pain and fatigue. Future work will identify optimal PRO tools for different settings but, despite current limitations, they are ready to be incorporated into patient care.

A Self-Report Multidimensional Health Assessment Questionnaire (MDHAQ) for Face-To-Face or Telemedicine Encounters to Assess Clinical Severity (RAPID3) and Screen for Fibromyalgia (FAST) and Depression (DEP)

Purpose of Review

To update the clinical value of a patient self-report multidimensional health assessment questionnaire (MDHAQ).

Recent Findings

The MDHAQ includes 10 individual quantitative scores for physical function, pain, patient global assessment, fatigue, sleep, anxiety, depression, morning stiffness, change in status, and exercise status, and 5 indices, RAPID3 (routine assessment of patient index data) to assess clinical status in all diseases studied, FAST3 (fibromyalgia assessment screening tool) and MDHAQ-Dep (depression) to screen for fibromyalgia and/or depression, RADAI self-report of specific painful joints and joint count, and a symptom checklist for review of systems, and recognition of flares and medication adverse events. The MDHAQ also uniquely queries traditional “medical” information concerning comorbidities, falls, trauma, new symptoms, illnesses, surgeries, hospitalizations, emergencies, medication changes, and medication side effects. Three MDHAQ versions include long for new patients, short for new and return patients, and telemedicine. An electronic MDHAQ (eMDHAQ) has been developed with software that can interface with any electronic medical record (EMR) through the HL7 FHIR standard. However, EMR collaboration and implementation have proven difficult.

Summary

An MDHAQ provides a quantitative overview of patient status with far more information and documentation than an interview, involving minimal extra work for the physician.

Association of Medication Access Difficulty and COVID-19-Related Distress With Disease Flares in Rheumatology Patients During the COVID-19 Pandemic

OBJECTIVE

Due to concerns of infection and medication disruptions during the COVID-19 pandemic, rheumatology patients at the pandemic epicenter were at risk of distress and poor health outcomes. We sought to investigate medication disruptions and COVID-19-related distress in the Bronx, New York shortly after the peak of the pandemic and determine whether factors related to the pandemic were associated with flares, disease activity, and overall health.

METHODS

In the month following the epidemic peak, we surveyed adult patients and parents of pediatric patients from rheumatology clinics in the Bronx regarding medication access, medication interruptions, COVID-19 infection, COVID-19 hospitalization, and COVID-19-related distress. We examined which factors were associated with patient-reported flares, disease activity, and overall health scores in regression models accounting for sociodemographic characteristics and rheumatologic disease type.

RESULTS

Of the 1,692 patients and parents of pediatric patients that were contacted, 361 (21%) responded; 16% reported medication access difficulty, 14% reported medication interruptions, and 41% reported experiencing flare(s). In a multivariable logistic regression model, medication access difficulty was associated with increased odds of flare (odds ratio [OR] 4.0 [95% confidence interval (95% CI) 1.5, 10.4]; P = 0.005), as was high COVID-19-related distress (OR 2.4 [95% CI 1.2, 4.6]; P = 0.01). In multivariable linear regression models, medication access difficulty and high COVID-19-related distress were associated with worse disease activity scores, and high COVID-19-related distress was associated with worse health scores.

CONCLUSION

Medication access difficulties and flares were common among rheumatology patients from the Bronx, New York in the month following the peak of the epidemic. Medication access difficulty and COVID-19-related distress were highly associated with flare and disease activity. COVID-19-related distress was associated with overall health scores.

Patient-Reported Outcomes in Lupus

Patient-reported outcome (PRO) was identified as a core systemic lupus erythematosus (SLE) outcome in 1999. More than 20 years later, however, generic PRO measures evaluating impact in SLE are used mainly for research. Generic and disease-targeted PRO tools have unique advantages. Significant progress in identification of patient disease-relevant PRO concepts and development of new PRO tools for SLE has occurred over the past 20 years. Further research needs to focus on responsiveness and minimally important differences of existing, promising PRO tools to facilitate their use in SLE patient care and research.

Fibromyalgia Assessment Screening Tool: Clues to Fibromyalgia on a Multidimensional Health Assessment Questionnaire for Routine Care

OBJECTIVE

To develop feasible indices as clues to comorbid fibromyalgia (FM) in routine care of patients with various rheumatic diseases based only on self-report multidimensional Health Assessment Questionnaire (MDHAQ) scores, which are informative in all rheumatic diagnoses studied.

METHODS

All patients with all diagnoses complete an MDHAQ at each visit; the 2011 FM criteria questionnaire was added to the standard MDHAQ between February 2013 and August 2016. The proportion of patients who met 2011 FM criteria or had a clinical diagnosis of FM was calculated. Individual candidate MDHAQ measures were compared to 2011 FM criteria using receiver-operating characteristic (ROC) curves; cutpoints to recognize FM were selected from the area under the curve (AUC) for optimal tradeoff between sensitivity and specificity. Cumulative indices of 3 or 4 MDHAQ measures were analyzed as fibromyalgia assessment screening tools (FAST).

RESULTS

In 148 patients, the highest AUC in ROC analyses versus 2011 FM criteria were seen for MDHAQ symptom checklist, self-report painful joint count, pain visual analog scale (VAS), and fatigue VAS. The optimal cutpoints were ≥ 16/60 for symptom checklist, ≥ 16/48 for self-report painful joint count, and ≥ 6/10 for both pain and fatigue VAS. Cumulative FAST indices of 2/3 or 3/4 MDHAQ measures correctly classified 89.4-91.7% of patients who met 2011 FM criteria.

CONCLUSION

FAST3 and FAST4 cumulative indices from only MDHAQ scores correctly identify most patients who meet 2011 FM criteria. FAST indices can assist clinicians in routine care as clues to FM with a general rheumatology rather than FM-specific questionnaire.

Fibromyalgia Assessment Screening Tools (FAST) Based on Only Multidimensional Health Assessment Questionnaire (MDHAQ) Scores as Clues to Fibromyalgia

Objective

The study was designed to develop fibromyalgia assessment screening tool (FAST) indices based only on multidimensional health assessment questionnaire (MDHAQ) scores as clues to fibromyalgia (FM), analyzed for possible agreement with the 2011 FM criteria.

Methods

All patients with all diagnoses complete an MDHAQ at each visit in routine care. The MDHAQ includes scores for physical function, pain, global assessment, fatigue, self-report painful joint count, and a 60-symptom checklist. MDHAQ items similar or identical to the 2011 FM criteria symptom severity scale (SSS) and widespread pain index (WPI) components of a polysymptomatic distress scale (PSD) were compiled into continuous MDHAQ-FM-SSS, MDHAQ-FM-WPI, and MDHAQ-FM-PSD indices. Ten candidate MDHAQ scores were analyzed against the 2011 FM criteria using descriptive statistics, Spearman correlations, kappa statistics, and receiver operating characteristic curves for the area under the curve (AUC). MDHAQ candidate variables with the highest AUC were compiled into cumulative MDHAQ-FAST indices of three (FAST3) or four (FAST4) scores.

Results

The highest AUCs among MDHAQ scores were seen for symptom checklist, painful joint count, fatigue, and pain, which are included in FAST4; FAST3-F excludes pain, and FAST3-P excludes fatigue. AUCs for FAST3-P, FAST3-F, and FAST4, as well as continuous MDHAQ-FM scores, all were greater than 0.92, indicating excellent criterion validity. Kappa statistics versus the 2011 criteria were 0.63-0.68, higher than 0.41-0.47 versus physician ICD-10 diagnoses.

Conclusion

Pragmatic FAST3, FAST4, and MDHAQ-FM indices are similar to FM criteria to screen for FM in routine care. It is more feasible to collect the same MDHAQ, which is informative in all rheumatic diseases studied, from each patient than to ask different patients with different diagnoses to complete different questionnaires.

Disease Burden in Osteoarthritis Is Similar to That of Rheumatoid Arthritis at Initial Rheumatology Visit and Significantly Greater Six Months Later

OBJECTIVE

To analyze disease burden in osteoarthritis (OA) according to Multidimensional Health Assessment Questionnaire (MDHAQ)/Routine Assessment of Patient Index Data 3 (RAPID3) scores at the initial visit and the 6-month follow-up visit, compared with rheumatoid arthritis (RA) as a benchmark for high disease burden.

METHODS

All patients with all diagnoses at the Rush University Medical Center Division of Rheumatology complete a paper MDHAQ at all visits, saved as a PDF in the electronic health record. MDHAQ 0-10 scores for physical function, pain, and patient global assessment (compiled into RAPID3 0-30 scores) and additional scales at the initial and 6-month follow-up visits, for new OA and RA patients seen from 2011 to 2017, were compared. OA and RA patients were classified as self-referred or physician-referred, and RA patients were classified as disease-modifying antirheumatic drug (DMARD)-naive or having prior-DMARD treatment. Patient groups were compared using t-tests and analysis of variance, adjusted for age, disease duration, body mass index (BMI), education, and ethnicity.

RESULTS

Compared with RA patients, OA patients had higher age, BMI, and disease duration. At initial visit, the mean RAPID3 did not differ significantly in OA versus DMARD-naive RA patients, whether self- or physician-referred (range 14.8-16.4 [P = 0.38]), or in all OA patients versus DMARD-naive RA patients versus prior-DMARD RA patients (15.0, 15.7, and 15.8, respectively [P = 0.49]). After 6 months, RAPID3 was improved to 13.3, 10.3, and 10.8, respectively, which represented substantially greater improvement in RA patients than OA patients (P < 0.001). Similar results were seen for most self-reported measures and in adjusted analyses.

CONCLUSION

MDHAQ/RAPID3 scores are similar in OA and RA patients at the initial visit, but higher in OA patients than in RA patients 6 months later, reflecting superior RA treatments. The same MDHAQ/RAPID3 allows comparisons of disease burdens in different diseases.

Value of the Routine Assessment of Patient Index Data 3 in Patients With Psoriatic Arthritis: Results From a Tight-Control Clinical Trial and an Observational Cohort

OBJECTIVE

To analyze the Routine Assessment of Patient Index Data 3 (RAPID3), a patient-reported, composite index, designed initially for feasibility in clinical care. RAPID3 was developed in rheumatoid arthritis, but has been found useful in many rheumatic diseases. We analyzed RAPID3 in patients with psoriatic arthritis (PsA).

METHODS

Post hoc analyses were performed on 2 independent data sets, the Tight Control of Psoriatic Arthritis (TICOPA) clinical trial, and the Long-Term Outcome in Psoriatic Arthritis Study (LOPAS II), an observational cohort. RAPID3 (range 0-30) is the total of three 0-10 scores for the Health Assessment Questionnaire disability index (recalculated from 0-3), pain visual analog scale (VAS), and global VAS. RAPID3 scores were compared to the Psoriatic Arthritis Disease Activity Score (PASDAS), the Disease Activity in Psoriatic Arthritis (DAPSA), and other available clinical measures, according to Spearman's correlation coefficients, standardized response mean, SEM, smallest detectible difference, minimally important difference (in patients who improved), and receiver operating characteristic curves. RAPID3 remission was compared to criteria for both standard minimal disease activity (MDA) and very low disease activity (VLDA).

RESULTS

RAPID3 was correlated significantly with PASDAS in TICOPA (r = 0.79, P < 0.01) and with DAPSA in LOPAS II (ρ = 0.59, P < 0.01), and with most other measures in both data sets. RAPID3 discriminated between tight control and standard care in TICOPA at 48 weeks at levels comparable to DAPSA and the PASDAS (P < 0.01). RAPID3 remission discriminated treatment groups in TICOPA intermediate between MDA and VLDA criteria.

CONCLUSION

RAPID3 appears comparably informative to PASDAS and DAPSA in PsA, with greater feasibility for routine clinical care.

Predictors of disability in a childhood-onset systemic lupus erythematosus cohort: results from the CARRA Legacy Registry

Objective Few descriptions of physical disability in childhood-onset SLE (cSLE) exist. We sought to describe disability in a large North American cohort of patients with cSLE and identify predictors of disability. Methods Sociodemographic and clinical data were obtained from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Legacy Registry for patients with cSLE enrolled between May 2010 and October 2014. The Childhood Health Assessment Questionnaire (CHAQ) was used to assess disability and physical functioning. Chi-square tests were used for univariate analyses, and multivariate logistic regression was used to assess predictors of disability. Results We analyzed data for 939 patients with cSLE. The median and mean CHAQ scores were 0 and 0.25, respectively, and 41% of the cohort had at least mild disability. Arthritis and higher pain scores were significantly associated with disability as compared to those without disability ( p < 0.001). In multivariate logistic regression analysis, low annual income, arthritis, and higher pain scores were associated with disability at baseline. Conclusions Disability as measured by baseline CHAQ was fairly common in cSLE patients in the CARRA Legacy Registry, and was associated with low household income, arthritis, and higher pain scores. In addition to optimal disease control, ensuring psychosocial supports and addressing pain may reduce disability in cSLE. Further study is needed of disability in cSLE.

Perspectives of Medical Specialists From Different Disciplines on the Management of Systemic Lupus Erythematosus: An Interview Study

OBJECTIVE

Systemic lupus erythematosus (SLE) is a complex autoimmune disease that can affect multiple organ systems, with specialists from many disciplines often involved, which may lead to inconsistent care. We aimed to describe the attitudes and perspectives of specialists from different medical disciplines on the management of people with SLE.

METHODS

Face-to-face semistructured interviews were conducted with rheumatologists (n = 16), nephrologists (n = 16), and immunologists (n = 11) providing care to adults with SLE from 19 centers across Australia in 2015. All interviews were transcribed and analyzed thematically.

RESULTS

Five themes were identified: uncertainties in judgments (hampered by unknown and unclear etiology, inapplicable evidence, comprehending information dispersion), reflexive responses (anchoring to specialty training, anticipating outcomes, avoiding disaster, empathy for the vulnerable), overarching duty to patients (achieving patient priorities, maximizing adherence, controlling the disease, providing legitimate information, having adequate and relevant expertise), safeguarding professional opportunities (diversifying clinical skills, protecting colleagues' interests), and optimizing access to treatment (capitalizing on multidisciplinary care, acquiring breakthrough therapies).

CONCLUSION

Specialists strive to deliver evidence-informed patient-centered care, but recognize that they are anchored by their training. To overcome uncertainties in clinical management due to lack of high-quality evidence and specialty silo structures, specialists translated evidence from other disease settings and collaborated with other specialists in routine care. Developing robust evidence, tools to support evidence-informed decisions, and multidisciplinary shared-care pathways may improve the management of people with this complex disease.

Effects of Hydroxychloroquine in Patients With Cutaneous Lupus Erythematosus: A Multicenter, Double-Blind, Randomized, Parallel-Group Trial

OBJECTIVE

To assess the efficacy and tolerability of hydroxychloroquine (HCQ) in patients with cutaneous lupus erythematosus (CLE), in a phase III clinical trial conducted in Japan.

METHODS

We conducted a double-blind, randomized, parallel-group clinical trial. This was a baseline-controlled study, and the group differences were evaluated in an exploratory analysis. A total of 103 patients with active CLE (according to a Cutaneous Lupus Erythematosus Disease Area and Severity Index [CLASI] activity score of ≥4) were included. Patients were randomized 3:1 to receive HCQ or placebo during the 16-week double-blind period, and all patients were given HCQ during the following 36-week single-blind period. The primary efficacy end point was a reduction in the CLASI activity score at week 16. The secondary end points included the central photo evaluation (5-point scale), patient's global assessment (7-point scale), the Skindex-29 score, and investigator's global assessment (7-point scale, based on the other 3 secondary end points). In patients with systemic lupus erythematosus, fatigue and musculoskeletal pain were assessed. Safety was assessed up to week 55.

RESULTS

The mean CLASI score at week 16 was significantly improved from baseline in both the HCQ group and the placebo group: mean change -4.6 (95% confidence interval [95% CI] -6.1, -3.1) (P < 0.0001), and mean change -3.2 (95% CI -5.1, -1.3) (P = 0.002), respectively, without between-group difference (P = 0.197). The investigator's global assessment demonstrated a greater proportion of "improved" and "remarkably improved" patients in the HCQ group (51.4% versus 8.7% in the placebo group [P = 0.0002 between groups]). The other secondary end points supported the efficacy of HCQ. Cellulitis, drug eruption, hepatic dysfunction, and Stevens-Johnson syndrome were shown to be serious adverse events related to HCQ use.

CONCLUSION

The results of this randomized clinical trial support the efficacy and tolerability of HCQ in patients with CLE.

Responsiveness of a simple RAPID-3-like index compared to disease-specific BASDAI and ASDAS indices in patients with axial spondyloarthritis

Objective

To evaluate the responsiveness of a simple routine assessment of patient index data (RAPID3)-like index that includes only 3 patient self-report measures (physical function, pain and patient global estimate) compared to that of traditional composite indices to assess change in patients with axial spondyloarthritis (Ax-SpA).

Methods

Devenir des Spondylarthropathies Indifférenciées Récentes (DESIR) is a prospective cohort of patients with inflammatory back pain suggestive of Ax-SpA. The study included 461 patients, who met the Assessment of SpondyloArthritis International Society (ASAS) classification criteria for Ax-SpA. A simple RAPID3-like index was compared with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the AS Disease Activity Score (ASDAS) scores for responsiveness over 6 months. Construct validity was also evaluated through Pearson correlations and discrimination of disease activity through standardised mean differences for the 3 indices.

Results

The RAPID3-like index was correlated significantly with BASDAI (r=0.84, p<0.005) and ASDAS-C-reactive protein (CRP) (r=0.74, p<0.005), similar to correlations of BASDAI with ASDAS-CRP (r=0.76, p<0.005). The percentage of patients with inactive disease ranged from 9% to 25% and with high activity from 10% to 45%, according to various measures. The capacity to discriminate between high and low disease activity was similar for the 3 indices. The strength of agreement of RAPID3 with ASDAS-CRP was moderate (0.44) and lower with BASDAI (0.37). Responsiveness over 6 months was slightly higher for ASDAS-CRP and the RAPID3-like index than that for BASDAI.

Conclusions

The RAPID3-like index provides similar information to BASDAI and ASDAS-CRP concerning responsiveness over 6 months. RAPID3 appears feasible to assess patients with Ax-SpA quantitatively over time in busy clinical settings.

Routine Assessment of Patient Index Data (RAPID3) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Scores Yield Similar Information in 85 Korean Patients With Ankylosing Spondylitis Seen in Usual Clinical Care

Disease-specific ankylosing spondylitis (AS) indices, including BASDAI (Bath AS Disease Activity Index), BASFI (Bath AS Functional Index), ASDAS (AS Disease Activity Score), and BASMI (Bath AS Metrology Index), are widely used in clinical trials and in some clinical settings, but not in most routine care. Laboratory tests usually are the only quantitative measures included in routine care of AS patients, but often are poorly informative. Routine Assessment of Patient Index Data 3 (RAPID3) on a Multidimensional Health Assessment Questionnaire (MDHAQ) is feasible and informative in many rheumatic diseases.

Prediction of Remission in a French Early Arthritis Cohort by RAPID3 and other Core Data Set Measures, but Not by the Absence of Rheumatoid Factor, Anticitrullinated Protein Antibodies, or Radiographic Erosions

Objective.

To identify baseline variables that predict remission according to different criteria in rheumatoid arthritis (RA) in a comprehensive French ESPOIR early arthritis database.

Methods.

Individual variables and indices at baseline were analyzed in 664 patients for capacity to predict remission either 6 or 12 months later according to 4 criteria that require a formal joint count: the American College of Rheumatology/European League Against Rheumatism Boolean criteria, the Simplified Disease Activity Index, the Clinical Disease Activity Index, and the 28-joint Disease Activity Score; and 2 remission criteria that do not require a formal joint count: the Routine Assessment of Patient Index Data 3 (RAPID3) and the RAPID3 ≤ 3 + swollen joint, using univariate and multivariate logistic regressions.

Results.

Remission was predicted significantly 6 and/or 12 months later in 26.8%–51.4% of patients, according to all 6 criteria by younger age, low index scores, and better status for the 6/7 clinical RA core dataset measures: tender joint count, swollen joint count (SJC), physician’s global estimate, patient self-report Health Assessment Questionnaire (HAQ) physical function, pain, and patient’s global estimate. Remission was not predicted by the absence of “poor prognosis RA” indicators, rheumatoid factor (RF), anticitrullinated protein antibodies (ACPA), or radiographic erosions. In multivariate regressions that included only 3 variables, low HAQ function predicted remission by all criteria as effectively as SJC, erythrocyte sedimentation rate, or C-reactive protein.

Conclusion.

Younger age and 6 core dataset clinical measures, but not the absence of traditional “poor prognosis RA” indicators, RF, ACPA, or radiographic erosions, predicted remission according to 6 criteria, including 2 without a formal joint count.

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.

Patient-reported outcome measures for systemic lupus erythematosus clinical trials: a review of content validity, face validity and psychometric performance

Background

Despite overall progress in treatment of autoimmune diseases, patients with systemic lupus erythematosus (SLE) experience many inflammatory symptoms representing an unmet medical need. This study aimed to create a conceptual model of the humanistic and economic burden of SLE, and review the patient-reported outcomes (PROs) used to measure such concepts in SLE clinical trials.

Methods

A conceptual model for SLE was developed from structured review of published articles from 2007 to August 2013 identified from literature databases (MEDLINE, EMBASE, PsycINFO, EconLit) plus other sources (PROLabels, FDA/EMA websites, Clinicaltrials.gov). PROs targeting key symptoms/impacts were identified from the literature. They were reviewed in the context of available guidance and assessed for face and content validity and psychometric properties to determine appropriateness for use in SLE trials.

Results

The conceptual model identified fatigue, pain, cognition, daily activities, emotional well-being, physical/social functioning and work productivity as key SLE concepts. Of the 68 articles reviewed, 38 reported PRO data. From these and the other sources, 15 PROs were selected for review, including SLE-specific health-related quality of life (HRQoL) measures (n = 5), work productivity (n = 1), and generic measures of fatigue (n = 3), pain (n = 2), depression (n = 2) and HRQoL (n = 2). The Functional Assessment of Chronic Illness Therapy - Fatigue Scale (FACIT-Fatigue), Brief Pain Inventory (BPI-SF) and LupusQoL demonstrated the strongest face validity, conceptual coverage and psychometric properties measuring key concepts in the conceptual model. All PROs reviewed, except for three Lupus-specific measures, lacked qualitative SLE patient involvement during development. The Hospital Anxiety and Depression Scale (HADS), Short Form [36 item] Health Survey version 2 (SF-36v2), EuroQoL 5-dimensions (EQ-5D-3L and EQ-5D-5L) and Work Productivity and Activity Impairment Questionnaire: Lupus (WPAI:Lupus) showed suitability for SLE economic models.

Conclusions

Based on the identification of key symptoms and impacts of SLE using a scientifically sound conceptual model, we conclude that SLE is a condition associated with high unmet need and considerable burden to patients. This review highlights the availability and need for disease-specific and generic patient-reported measures of relevant domains of disease signs and symptoms, HRQoL and work productivity, providing useful insight for SLE clinical trial design.

MDHAQ/RAPID3 to recognize improvement over 2 months in usual care of patients with osteoarthritis, systemic lupus erythematosus, spondyloarthropathy, and gout, as well as rheumatoid arthritis

OBJECTIVE

To analyze whether MDHAQ (Multidimensional Health Assessment Questionnaire) scores for physical function (FN), pain, Patient Global Estimate (PATGL), and RAPID3 (Routine Assessment of Patient Index Data, a composite of these 3 measures) document improvement in patients with osteoarthritis, systemic lupus erythematosus, spondyloarthropathy, and gout, similarly to rheumatoid arthritis.

METHODS

In a solo rheumatology practice, every patient completes an MDHAQ/RAPID3 and is assigned a Physician Global Estimate (DOCGL) at every visit. Mean and median FN (0-10 scale), pain (0-10), PATGL (0-10), RAPID3 (0-30), and DOCGL (0-10) were computed at first visit and 2 months later in 141 new patients with 5 diagnoses. Proportions with RAPID3 high (>12), moderate (6.1-12), and low (3.1-6) severity and remission (≤3) were computed. Differences between baseline and 2-month follow-up for each diagnosis were analyzed using paired t tests. Mean changes over 2 months across 5 diagnoses were compared using analysis of variance.

RESULTS

Mean baseline scores for all measures were in narrow ranges for all 5 diagnoses: FN 1.5 to 2.5, pain 4.2 to 5.9, PATGL 4.3 to 5.6, RAPID3 10.1 to 13.7, and DOCGL 2.4 to 4.0. Improvement for FN was 9.4% to 26.8% in all diagnoses but osteoarthritis, for pain 20.2% to 35.3% in all diagnoses, PATGL 11.3% to 30.4%, RAPID3 16.8% to 27.5%, and for DOCGL 23.8% to 36.4%, similar in 5 diagnostic groups.

CONCLUSIONS

MDHAQ, RAPID3, and DOCGL document similar baseline and improvement scores in patients with 5 diagnoses. These quantitative data may supplement traditional narrative, "gestalt" descriptions in usual care of patients with any rheumatic disease.

Assessment of disease activity, damage and quality of life in systemic lupus erythematosus: new aspects

Systemic lupus erythematosus (SLE) is a multisystem auto-immune disorder that results from a combination of genetic, environmental and hormonal factors. The heterogeneity of disease presentation and course in different individuals and the variability in the disease progression/fluctuations within the same patient have made finding a unifying assessment tool difficult. It is currently accepted that assessment of patients with SLE cannot be accomplished with a single index. Formal evaluation of three aspects of the disease, disease activity, disease damage and patient-related quality of life (QoL), is required. In the recent decade, the pathogenesis of SLE at the cellular and molecular levels has been the subject of much research. Robust assessment tools are needed to correlate the presence of various serological markers with disease activity. In addition, multiple clinical trials of new therapies have necessitated validated measures that can give a sensitive response index. This review focusses on the SLE assessment tools currently in use and their translational application in clinical research and trials.

Response to hydroxychloroquine in Japanese patients with systemic lupus erythematosus using the cutaneous lupus erythematosus disease area and severity index (CLASI)

We evaluated the cutaneous lupus erythematosus disease area and severity index (CLASI) in Japanese patients with systemic lupus erythematosus (SLE) in order to design a clinical trial of hydroxychloroquine (HCQ) in Japan. Our prospective cohort study consisted of seven SLE patients with active skin disease who started HCQ at Tokyo Metropolitan Tama Medical Center. The therapeutic responses were assessed at 4 months. Patients were categorized as responders (improved) or non-responders (unchanged or worsened) using the criteria of a 4-point or 20% decrease in the CLASI activity score. We also assessed joint pain determined by patient visual analog scale (VAS), malaise (VAS), patient global assessment of SLE (VAS), and constitutional and musculoskeletal symptoms according to the British Isles Lupus Assessment Group (BILAG) disease activity index. Six patients (86%) were categorized as responders. The median (range) CLASI activity score of all patients at assessment had changed from 8.0 (2-22) to 4 (2-10). All five patients with joint pain and all five patients with malaise showed improvement in patient VAS but the BILAG findings failed to capture these improvements. In conclusion, the cutaneous aspects of SLE can be measured by the CLASI. The CLASI activity score may be a reasonable primary endpoint when performing a clinical trial of HCQ.
