POS1460-HPR MYRA TOUCH FOR DISEASE ACTIVITY EVALUATION IN RHEUMATOID ARTHRITIS: A COMPARISON OF PATIENT-REPORTED OUTCOMES WITH PHYSICIAN’S ASSESSMENT

Background:Patient-reported outcomes (PROs) have become an essential component of patients’ assessment in the management of Rheumatoid Arthritis(RA).They have been reported to be at least as informative if not more than physician assessed outcomes.MyRA Touch was pioneered by the Rheumatology Unit of Hospital Tuanku Jaa’far in Seremban Malaysia in March 2018,to engage and empower all RA patients on their own disease activity monitoring. It is an electronic platform, designed to enhanced the application of electronic patient reported outcomes (ePROs) among RA patients where they examine and record their own painful and/or swollen joints for DAS28 calculation and report their health assessment through Routine Assessment of Patient Index Data with 3 Measures (RAPID 3).MyRA Touch is an applications (App) that is user friendly and available in four major spoken languages (English, Chinese, Malay and Tamil) with an animated version for patients who are illiterate.Objectives:The objectives of this study are to determine the correlation between:I)Patient-reported and physician reported DAS28 ESR/CRPII)RAPID3 and Clinical Disease activity Index (CDAI)III)RAPID3 and DAS28 ESR/CRP assessed by physician and patientIV)RAPID3 and inflammatory markers ESR/CRP.Methods:This was a cross-sectional study carried out in the Rheumatology Unit of Hospital Tuanku Jaa’far. All data entered through MyRA Touch App from April 2018 till April 2020 was analysed.Results:There were a total of 562 patients who entered the data in the App, 87.9% were women. The ethnic compositions of the study subjects comprised of Indians (36.7%) followed by the Malays (34.7%),Chinese (26.3%) and other ethnics (2.3%). About half of patients (59.8%) were in the 51-70 age group whereas 22.9%,1.8% and 15.5% were in the 31-50,18-30 and above 70 age groups respectively. The majority of our patients (96%) were literate. A total of 54.3% of them received secondary education, 27% primary, 12.2% tertiary and 6.6% did not receive any formal education.There was a high level of correlation between DAS28 ESR/CRP performed by patient and DAS28 ESR/CRP assessed by physician, (r=0.808 for DAS28 ESR and r=0.804 for DAS28 CRP). RAPID3 also showed high level of correlation with CDAI and DAS28 CRP assessed by patient (r=0.700 and r=0.718 respectively). There was a moderate correlation between DAS28 ESR/CRP done by physician with RAPID3 (r=0.656 and r=0.696 respectively).RAPID3 demonstrated little correlation with inflammatory markers ESR and CRP (r=0.141 and r=0.171 respectively).Conclusion:PROs via DAS 28 (ESR/CRP) and RAPID3 showed moderate to high correlation with disease activity assessed by physician. We can empower patients to perform their own disease assessment by using the MyRA Touch App before seeing their physician and the information provided in the App, can help to reduced consultation time. During the COVID-19 pandemic, telemedicine is very much encouraged. By using the MyRA Touch, patients can assess their own tender and swollen joint count on a homunculus, evaluate their own physical function, health and pain using the RAPID3 parameters. The information obtained from the PROs in the MyRA touch App enables the physician to make a more comprehensive virtual assessment of the patient’s condition which helps in treatment decision making. In conclusion, MyRA Touch is an useful tool for disease activity measurement by patient.References:[1]Jenny AA, Diana BC, Omar JC, et al.

Over Time

Objective.To evaluate the performance of patient-reported outcomes (PRO) as primary indices for identification and prediction of a 28-joint Disease Activity Score (DAS28) > 3.2 among patients with rheumatoid arthritis (RA).Methods.Patients with RA completed monthly online PRO [Health Assessment Questionnaire (HAQ), Rheumatoid Arthritis Disease Activity Index (RADAI), visual analog scale (VAS) fatigue] and were clinically assessed every 3 months using the DAS28. Simple descriptive statistics, logistic regression, and the Bayesian joint modeling approach were used to analyze the data. The Bayesian joint model combines the scores and changes in the scores of 3 PRO to predict a DAS28 > 3.2 at the subsequent timepoint.Results.A group of 159 patients with RA participated. Stratified summaries of the PRO by DAS28 categories at baseline provided incremental values of the PRO for more active disease. However, on an individual level, the DAS28 and the PRO fluctuated over time. The prediction of subsequent DAS score by a single instrument at single timepoints resulted in moderate sensitivity and specificity. Using the intercept and slope of the combined PRO of the first 3 measurements to predict the DAS28 state at 3 months resulted in a sensitivity of 0.81 and a specificity of 0.92. After 10-fold cross validation, the model had a sensitivity of 0.61 and specificity of 0.75 to identify patients with a DAS28 > 3.2.Conclusion.PRO showed fluctuating levels of disease activity over time, while on a group level disease activity stayed the same. Using the changes in RADAI, HAQ, and VAS fatigue over time to predict future DAS28 > 3.2 resulted in moderate performance after the internal cross-validation of the model (sensitivity 0.61, specificity 0.75).

Physician Awareness

ObjectiveTo explore the effect of apps measuring patient-reported outcomes (PROs) on patient–provider interaction in the rheumatic diseases in an observational setting.MethodsPatients in the Swiss Clinical Quality Management in Rheumatic Diseases Registry were offered mobile apps (iDialog and COmPASS) to track disease status between rheumatology visits using validated PROs (Rheumatoid Arthritis Disease Activity Index-5 score, Bath Ankylosing Spondylitis Disease Activity Index score, Routine Assessment of Patient Index Data-3 score and Visual Analogue Scale score for pain, disease activity and skin symptoms). We assessed two aspects of patient–provider interaction: shared decision making (SDM) and physician awareness of disease fluctuations. We used logistic regressions to compare outcomes among patients who (1) used an app and discussed app data with their physician (app+discussion group), (2) used an app without discussing the data (app-only group) or (3) did not use any app (non-app users).Results2111 patients were analysed, including 1799 non-app users, 150 app-only users and 162 app+discussion users (43% male; with 902 patients with rheumatoid arthritis, 766 patients with axial spondyloarthritis and 443 patients with psoriatic arthritis). App users were younger than non-app users (mean age of 47 vs 51 years, p<0.001). Compared with non-app users, the app+discussion group rated their rheumatologist more highly in SDM (OR 1.7, 95% CI 1.1 to 2.4) and physician awareness of disease fluctuations (OR 2.0, 95% CI 1.3 to 3.1). This improvement was absent in the app-only group.ConclusionApp users who discussed app data with their rheumatologist reported more favourably on patient–provider interactions than app users who did not and non-app users. Apps measuring PROs may contribute little to patient–provider interactions without integration of app data into care processes.

Effectiveness Studies

Background:Biologics for the treatment of rheumatoid arthritis (RA) have different modes of action to target auto-inflammatory processes causing the signs and symptoms of the disease. Different biologics may thus have different effects on inflammatory markers. For instance, previous studies have shown that the interleukin-6-inhibitor tocilizumab (TOC) decreases the level of acute phase reactants (APRs) [1]. Such direct effects on inflammatory markers may lead to an overestimation of clinical response if disease activity is measured via scores including inflammatory markers, such as the Disease Activity Score 28 (DAS 28). The detected changes in disease activity may not adequately reflect the clinical improvement of signs and symptoms.Objectives:In our study, we compared biologics with each other using two different disease activity scores: the DAS 28 including APRs and the clinical disease activity index (CDAI) excluding APRs. The aim of this study was to assess whether the use of the two different scores affects comparative effectiveness studies on biologics for the treatment of RA.Methods:We compared results on the comparative effectiveness of biologics using the corresponding thresholds for low disease activity (LDA) for the DAS 28 (< 3.2) and the CDAI (≤ 10). We performed two separate network meta-analyses (NMAs) after a thorough step-by-step evaluation of the similarity, homogeneity and consistency assumptions of the patient populations and the study data.Our study formed part of a systematic review (including NMAs) that was largely based on clinical study reports and re-analyses of LDA using individual patient data provided by sponsors for studies conducted up to 2017. Thus, the analyses include hitherto unknown data on LDA analysed by means of the CDAI, especially data from older studies. An extensive comparison of DAS 28 and CDAI in different patient populations was possible.Results:For all analysed patient populations, comparisons of TOC versus other biologics yielded remarkable results: advantages for TOC were found in NMAs using the DAS 28, which were not confirmed in NMAs using the CDAI. For methotrexate (MTX)-naïve patients, using the DAS 28, TOC showed a greater benefit than abatacept (ABA), certolizumab pegol (CZP), and etanercept (ETA), which was not confirmed by the CDAI. In contrast, TOC showed less benefit than adalimumab (ADA) and ETA. For patients after MTX failure and using the DAS 28, TOC showed a greater benefit than ABA, ADA, anakinra (ANA), ETA, golimumab (GOL), and infliximab (INF). With the exception of ANA, these advantages were not confirmed by the CDAI. Similar differences between DAS 28 and CDAI were shown in patients treated with biologics in monotherapy or after failure of biologics.Conclusion:In comparative effectiveness studies of biologics, the assessment of LDA using the DAS 28 instead of the CDAI leads to a consistent overestimation of the benefit of TOC in all patient populations, regardless of pre-treatment or combined therapy with MTX. The inclusion of APRs in disease activity scores may thus introduce bias. A score excluding inflammatory markers should therefore be used to ensure valid results.References:[1]Smolen JS, Aletaha D.
