Monitoring of Disease Activity With a Smartphone App in Routine Clinical Care in Patients With Axial Spondyloarthritis

The real experience of reporting electronic patient-reported outcomes in patients with inflammatory arthritis and factors influencing participation: a scoping review

Inflammatory arthritis can result in pain, stiffness, fatigue, and reduce quality of life. Frequent monitoring of disease activity is necessary for patients with inflammatory arthritis, and electronic patient-reported outcomes (ePROs) play a crucial role in this process. This study aimed to investigate the real experience of reporting ePROs in patients with inflammatory arthritis, as well as to identify factors influencing participation. The ultimate goal was to inform targeted strategies and develop interventions to enhance the utilization of ePROs in clinical settings. A scoping review was performed using PubMed, Web of science, Embase, and the Cochrane library from 2000 to the present and the literature search focused on the experience of reporting ePROs in inflammatory arthritis and the factors that influence participation. Screening articles based on inclusion and exclusion criteria. A total of 1478 studies were identified, out of which 26 were included in the review. The top experience of applications/platforms in patients was that they were easy to use and that the applications were clear, logical and intuitive. A summary of 18 potential influencing factors were identified and there was inconsistent evidence for five of these factors. The participation of reporting ePROs is influenced by various factors, and the experience is a crucial aspect in patients with inflammatory arthritis. Analyzing patients' experience and influencing factors provides a theoretical basis for future interventions to facilitate the clinical application of ePRO. However, further research is needed to fully understand the association between influencing factors and intervention outcomes.

Complementary App-Based Yoga Home Exercise Therapy for Patients With Axial Spondyloarthritis: Usability Study

BACKGROUND

Axial spondyloarthritis (AS) is a chronic inflammatory rheumatic disease characterized by potentially disabling inflammation of the spine and adjacent joints. Regular exercise is a cornerstone of treatment. However, patients with AS currently have little support. YogiTherapy (MaD Lab) is an app developed to support patients with AS by providing instructions for yoga-based home exercise therapy.

OBJECTIVE

This study aimed to evaluate the usability and acceptance of the newly designed YogiTherapy app for patients with AS.

METHODS

Patients completed the User Version of the Mobile Application Rating Scale (uMARS) and net promoter score (NPS) questionnaires after the app introduction. Wilcoxon Mann-Whitney rank sum test, chi-square test for count data, and correlation analysis were conducted to examine the usability of the app, acceptance, and patient characteristics.

RESULTS

A total of 65 patients with AS (33, 51% female; age: mean 43.3, SD 13.6 years) were included in the study from May 2022 to June 2023. Subsequently, the data were analyzed. Usability was rated moderate, with a mean uMARS of 3.35 (SD 0.47) points on a scale from 0 to 5. The highest-rated uMARS dimension was information (mean 3.88, SD 0.63), followed by functionality (mean 3.84, SD 0.87). Females reported a significantly higher uMARS total score than males (mean 3.47, SD 0.48 vs mean 3.23, SD 0.45; P=.03, Vargha and Delaney A [VDA] 0.66, 95% CI 0.53-0.77). The mean average of the NPS was 6.23 (SD 2.64) points (on a scale from 0 to 10), based on 43% (26/65 nonpromoters, 42% (25/65) indifferent, and 15% (9/65) promoters. A total of 7% (5/65) of those surveyed did not answer the question. When applying the NPS formula, the result is -26%. The NPS showed a positive correlation with the usage of mobile apps (r=0.39; P=.02). uMARS functionality was significantly higher rated by patients younger than 41 years (mean 4.17, SD 0.55 vs mean 3.54, SD 1; P<.001; VDA 0.69, 95% CI 0.56-0.80). Patients considering mobile apps as useful reported higher uMARS (r=0.38, P=.02). The uMARS app quality mean score was correlated with the frequency of using apps (r=-0.21, P<.001).

CONCLUSIONS

The results revealed moderate acceptance and usability ratings, prompting further app improvement. Significant differences were observed between age and gender. Our results emphasize the need for further improvements in YogiTherapy.

Diagnosis, monitoring, and management of axial spondyloarthritis

Axial spondyloarthritis (axSpA) is a chronic condition predominantly affecting the spine and sacroiliac joints. This article provides an in-depth overview of the current approaches to diagnosing, monitoring, and managing axSpA, including insights into developing terminology and diagnostic difficulties. A substantial portion of the debate focuses on the challenging diagnostic procedure, noting the difficulty of detecting axSpA early, particularly before the appearance of radiologic structural changes. Despite normal laboratory parameters, more than half of axSpA patients experience symptoms. X-ray and magnetic resonance imaging (MRI) are essential for evaluating structural damage and inflammation. MRI can be beneficial when there is no visible structural damage on X-ray as it can help unravel bone marrow edema (BME) as a sign of ongoing inflammation. The management covers both non-pharmacological and pharmacological approaches. Lifestyle modifications, physical activity, and patient education are essential components of the management. Pharmacological therapy, including nonsteroidal anti-inflammatory drugs (NSAIDs) and biologic disease-modifying anti-rheumatic drugs (bDMARDs), are explored, emphasizing individualized treatment. To effectively manage axSpA, a comprehensive and well-coordinated approach is necessary, emphasizing the significance of a multidisciplinary team. Telehealth applications play a growing role in axSpA management, notably in reducing diagnostic delays and facilitating remote monitoring. In conclusion, this article underlines diagnostic complexities and emphasizes the changing strategy of axSpA treatment. The nuanced understanding offered here is designed to guide clinicians, researchers, and healthcare providers toward a more comprehensive approach to axSpA diagnosis and care.

Evaluation of a hybrid telehealth care pathway for patients with axial spondyloarthritis including self-sampling at home: results of a longitudinal proof-of-concept mixed-methods study (TeleSpactive)

Patients with axial spondyloarthritis (axSpA) require close monitoring to achieve the goal of sustained disease remission. Telehealth can facilitate continuous care while relieving scarce healthcare resources. In a mixed-methods proof-of-concept study, we investigated a hybrid telehealth care axSpA pathway in patients with stable disease over 6 months. Patients used a medical app to document disease activity (BASDAI and PtGA bi-weekly, flare questionnaire weekly). To enable a remote ASDAS-CRP (TELE-ASDAS-CRP), patients used a capillary self-sampling device at home. Monitoring results were discussed and a decision was reached via shared decision-making whether a pre-planned 3-month on-site appointment (T3) was necessary. Ten patients completed the study, and eight patients also completed additional telephone interviews. Questionnaire adherence was high; BASDAI (82.3%), flares (74.8%) and all patients successfully completed the TELE-ASDAS-CRP for the T3 evaluation. At T3, 9/10 patients were in remission or low disease activity and all patients declined the offer of an optional T3 on-site appointment. Patient acceptance of all study components was high with a net promoter score (NPS) of +50% (mean NPS 8.8 ± 1.5) for self-sampling, +70% (mean NPS 9.0 ± 1.6) for the electronic questionnaires and +90% for the T3 teleconsultation (mean NPS 9.7 ± 0.6). In interviews, patients reported benefits such as a better overview of their condition, ease of use of telehealth tools, greater autonomy, and, most importantly, travel time savings. To our knowledge, this is the first study to investigate a hybrid approach to follow-up axSpA patients including self-sampling. The positive results observed in this scalable proof-of-concept study warrant a larger confirmatory study.

How to Monitor Disease Activity of Axial Spondyloarthritis in Clinical Practice

PURPOSE OF REVIEW

Treatment guided by periodic and quantitative data assessment results in better outcomes compared to using clinical gestalt. While validated generic as well as specific disease activity measures for axial spondyloarthritis (axSpA) are available, there is vast scope to improve their actual utilization in routine clinical practice. In this review, we discuss available disease activity measures for axSpA, describe results from the survey conducted among general rheumatologists as well as Spondyloarthritis Research and Treatment Network (SPARTAN) members about disease activity measurement in daily practice, and discuss ways to improve axSpA disease activity using technological advances. We also discuss the definitions of active disease and target for the treatment of axSpA.

RECENT FINDINGS

The 2019 American College of Rheumatology (ACR)/Spondylitis Association of America (SAA)/Spondyloarthritis Research and Treatment Network (SPARTAN) axSpA treatment guidelines conditionally recommend the regular monitoring of disease activity using a validated measure such as Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) or Ankylosing Spondylitis Disease Severity Index (ASDAS). Assessment of Spondyloarthritis International Society (ASAS)-European Alliance of Associations for Rheumatology (EULAR) guidelines recommend ASDAS as the most appropriate instrument for the assessment of disease activity, preferably calculated using C-reactive protein (CRP). ASAS has selected a core set of variables which were updated recently and have been endorsed by the Outcome Measures in Rheumatology Clinical Trials (OMERACT) group in order to bring homogeneity in assessment of axSpA. In a recent study, Patient-Reported Outcomes Measurement Information System (PROMIS®) measures were able to discriminate inactive, moderate, and high-very high ASDAS activity groups. A newly developed semi-objective index P4 (pain, physical function, patient global, and physician global) correlates well with BASDAI and ASDAS in axSpA and can also be used for other rheumatic diseases in busy clinical practices. Regular disease activity monitoring is critical for long-term management of axSpA and shared decision-making. The integration of electronic health records and smart devices provides a great opportunity to capture patient-reported data. Automated capture of electronic patient-reported outcome measures (ePROMs) is a highly efficient way and results in consistent regular monitoring and may improve the long-term outcomes. While currently used measures focus only on musculoskeletal symptoms of axSpA, a composite disease activity measure that can also incorporate extra-articular manifestations may provide a better assessment of disease activity.

Pre-assessment of patients with suspected axial spondyloarthritis combining student-led clinics and telemedicine: a qualitative study

OBJECTIVE

Patients referred to rheumatologists are currently facing months of inefficient waiting time due to the increasing demand and rising workforce shortage. We piloted a pre-assessment of patients with suspected axial spondyloarthritis (axSpA) combining student-led clinics and telemedicine (symptom assessment, symptom monitoring and at-home capillary self-sampling) to improve access to rheumatology care. The aim of this study was to explore (1) current challenges accessing axSpA care and (2) patients' first-hand experiences.

METHODS

Embedded within a clinical trial, this study was based on qualitative interviews with patients with suspected axSpA (n = 20). Data was analysed via qualitative content analysis.

RESULTS

Student-led clinics were perceived as high-quality care, comparable to conventional rheumatologist-led visits. Patients expressed that their interactions with the students instilled a sense of trust. History-taking and examinations were perceived as comprehensive and meticulous. Telehealth tools were seen as empowering, offering immediate and continuous access to symptom assessment at home. Patients reported a lack of specificity of the electronic questionnaires, impeding accurate responses. Patients requested a comments area to supplement questionnaire responses. Some patients reported receiving help to complete the blood collection.

CONCLUSION

Patients' access to rheumatology care is becoming increasingly burdensome. Pre-assessment including student-led clinics and telemedicine was highly accepted by patients. Patient interviews provided valuable in-depth feedback to improve the piloted patient pathway.

[Digital rheumatology]

Chronic inflammatory rheumatic diseases mostly run an undulating course and with unspecific symptoms. The initial clarification and timely initiation of treatment are challenging, which is additionally exacerbated by the lack of specialized physicians. Digital approaches, including artificial intelligence (AI), should be of assistance and enable an improved, personalized and needs-based treatment; however, the evidence is currently still very limited. This article provides a compact overview of the current state of digital rheumatology.

Student-led clinics and ePROs to accelerate diagnosis and treatment of patients with axial spondyloarthritis: results from a prospective pilot study

We aimed to investigate (1) student-led clinics and (2) electronic patient-reported outcomes (ePROs) to accelerate diagnosis and treatment of patients with axial spondyloarthritis (axSpA). Patients with suspected axSpA completed an initial student-led clinic visit (T-1) prior to their planned actual rheumatologist visit (T0). Acceleration of patient appointment and NSAID therapy start, availability of diagnostic findings, and treatment response at T0 were evaluated. Beginning at T-1, patients completed electronic BASDAI questionnaires every 2 weeks. Concordance of paper-based and electronic BASDAI was evaluated. Patient acceptance of ePRO reporting and student-led clinics was measured using the net promoter score (NPS). 17/36 (47.2%) included patients were diagnosed with axSpA. Student-led clinics (T-1) significantly accelerated patient appointments by more than 2 months (T0, T-1, p < 0.0001) and axSpA guideline-conform NSAID treatment (p < 0.0001). At T0, diagnostic workup was completed for all patients and 7/17 (41.2%) axSpA patients presented with a clinically important improvement or were in remission. 34/36 (94.4%) patients completed at least 80% of the ePROs between T-1 and T0. Electronic and paper-administered BASDAI correlated well (r = 0.8 p < 0.0001). Student-led clinics and ePROs were well accepted by patients with NPS scores of + 62.0% (mean ± SD 9.2/10.0 ± 0.9) and + 30.5% (mean ± SD 8.0/10.0 ± 1.7), respectively. In conclusion, student-led clinics and ePRO monitoring were well accepted, accelerated diagnostic workup and treatment in patients with axSpA.

Patients' awareness towards physical activity in the treatment of axial spondyloarthritis

INTRODUCTION

The course of axial spondyloarthritis (axSpA) is often characterized by impairments in physical function and mobility. Regular physical activity (PA) is a cornerstone of axSpA management. Recent European League Against Rheumatism (EULAR) recommendations for PA have stressed the importance of their implementation.

OBJECTIVE

Cohort study to investigate the awareness on and individual implementation of axSpA patients towards PA.

METHODS

Patients with axSpA and impaired physical function (Bath AS Functional Index [BASFI] score≥2.0) were recruited consecutively. All patients underwent a clinical examination including assessments of disease activity, physical function, mobility and global functioning. Patients also had to fill out structured questionnaires on knowledge, awareness and individual attitudes to PA.

RESULTS

Out of a total of 100 patients enrolled, 96 were included. Most respondents (n=82, 85.4%) were aware that PA has significant health benefits for patients with axSpA. Even though less than half of the patients (n=44, 42.7%) were aware that actual EULAR recommendations do exist, 45 patients (46.9%) did already fulfill these in terms of frequency/week. The majority of patients (n=61, 67.7%) had been informed about the benefits of PA by their physician, and physiotherapy had often been prescribed (n=61, 63.3%). Many patients (n=51, 53.1%) reported to perform individual exercise programs, and some (n=22, 22.9) supervised PA.

CONCLUSION

Even though the majority of axSpA patients are not aware of the recent EULAR recommendations for PA, many understand and agree that PA is beneficial for their health status. Health care providers should concentrate on the patients who are not active and do not know about the benefits of PA.

Real-world usage of digital health applications (DiGA) in rheumatology: results from a German patient survey

Mobile health applications and digital therapeutics (DTx) aim to improve current patient care. Real-world data on DTx are, however, scarce. The aim of this study was to evaluate the adherence, acceptance, and efficacy of DTx in a clinical routine rheumatology setting. We conducted a prospective observational cohort study assessing the use, adherence, acceptance, and efficacy of the DTx DiGA (Digitale Gesundheitsanwendungen) by survey over 12 weeks. Patients included had to have a rheumatic disease and had been prescribed a DiGA. Acceptance was assessed using the Net promoter score (NPS). 48 patients were prescribed DiGA. Of these, 39/48 (81%) completed the follow-up survey. 21/39 (54%) patients downloaded the DTx and 20/39 (51%) used the DTx at least once. 9/39 (23%) of patients stopped quickly afterward and 5/39 (13%) reported having completed the whole DTx program. Lack of time and commitment were reported as the main reasons for non-use. Overall acceptance of DiGA was high (Net promoter score (NPS) mean (SD) 7.8/10 (2.3)). While the majority of patients (60%) reported no improvement, one subgroup of patients (7/20, 35%) who regularly used an exercise-based DTx for back pain reported symptom improvement. Acceptance of DTx in patients with rheumatic diseases is high, however onboarding to DTx use and adherence to DTx is still challenging in patients with rheumatic diseases. In a subgroup of patients with back pain, however, the use of an exercise-based DTx led to symptom improvement.

Digitally supported shared decision-making and treat-to-target in rheumatology: a qualitative study embedded in a multicenter randomized controlled trial

Patient-reported outcomes (PRO) represent a cornerstone in the management of patients with rheumatoid arthritis (RA). However, PRO are currently recorded mainly on paper and only during on-site appointments. Electronic PRO (ePRO) enable continuous remote monitoring and could improve shared decision-making (SDM) and implementation of a treat-to-target (T2T) approach. This study aims to investigate patient and physician experiences, perceived drawbacks and benefits of using an ePRO web-app (ABATON RA) to digitally support SDM and T2T. A qualitative study embedded in a multicenter randomized controlled trial (RCT) consisting of interviews with RA patients and physicians that were subsequently analyzed using deductive-inductive qualitative content analysis. Between August 2021 and May 2022, interviews with ten RA patients and five physicians were completed. Three key themes emerged in the analysis: (i) App user experiences; (ii) perceived drawbacks of app-supported rheumatology care; and (iii) perceived benefits of app-supported rheumatology care. Continuous ePRO collection and a high level of standardization strained some RA patients. Certain ePRO seemed outdated and were hard to understand. Patients and physicians appreciated having an improved overview of disease activity, capturing disease flares and continuous remote monitoring. Paper- and time-saving were associated with using ePRO. Physicians feared to become too focused on ePRO data, stressed the lack of ePRO monitoring reimbursement and app interoperability. For RA patients and physicians, benefits seemed to outweigh observed drawbacks of the digitally supported SDM using ePRO. The software was easy to use and could lead to a better understanding of the individual disease course, resource allocation and treatment of rheumatoid arthritis.

Facilitators and barriers to adhere to monitoring disease activity with ePROs: a focus group study in patients with inflammatory arthritis

Telemonitoring disease activity with electronic patient-reported outcomes (ePROs) may reduce the workload of rheumatic care by decreasing outpatient clinic visits. However, low adherence to reporting ePROs is frequently observed. Our objective was to identify facilitators and barriers to weekly monitoring of disease activity with ePROs. Patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), or ankylosing spondylitis (AS) who recently participated in one of the two telemonitoring studies with ePROs completed in a smartphone app, were invited to participate in focus group discussions (FGD). Thematic analysis was used to identify themes that play a role in the decision to continue or stop reporting weekly ePROs. A total of 22 patients participated in three FGDs. Five themes were identified that were of importance to adhere to telemonitoring: (1) questionnaire frequency, (2) discussing results of completed ePROs, (3) physical consultations, (4) patient insight into disease activity and (5) user experience of the app. All themes contained both barrier and facilitator elements. The results suggest that to improve adherence to telemonitoring of disease activity with ePROs, the perceived benefits of completing ePROs should be maximized. This can be done by providing patients the ability to skip (unneeded) physical consultations in case of low disease activity, and training clinicians to always discuss the completed ePROs. In addition, it is essential to reduce the effort to report ePROs, by tailoring the frequency of ePROs based on the patients' disease activity or preference, aiming for optimal app functionality as well as by sending notifications when new ePROs are available.

Engagement and attrition with eHealth tools for remote monitoring in chronic arthritis: a systematic review and meta-analysis

OBJECTIVES

Although eHealth tools are potentially useful for remote disease monitoring, barriers include concerns of low engagement and high attrition. We aimed to summarise evidence on patients' engagement and attrition with eHealth tools for remotely monitoring disease activity/impact in chronic arthritis.

METHODS

A systematic literature search was conducted for original articles and abstracts published before September 2022. Eligible studies reported quantitative measures of patients' engagement with eHealth instruments used for remote monitoring in chronic arthritis. Engagement rates were pooled using random effects meta-analysis.

RESULTS

Of 8246 references, 45 studies were included: 23 using smartphone applications, 13 evaluating wearable activity trackers, 7 using personal digital assistants, 6 including web-based platforms and 2 using short message service. Wearable-based studies mostly reported engagement as the proportion of days the tracker was worn (70% pooled across 6 studies). For other eHealth tools, engagement was mostly reported as completion rates for remote patient-reported outcomes (PROs). The pooled completion rate was 80%, although between-study heterogeneity was high (I2 93%) with significant differences between eHealth tools and frequency of PRO-collection. Engagement significantly decreased with longer study duration, but attrition varied across studies (0%-89%). Several predictors of higher engagement were reported. Data on the influence of PRO-reporting frequency were conflicting.

CONCLUSION

Generally high patient engagement was reported with eHealth tools for remote monitoring in chronic arthritis. However, we found considerable between-study heterogeneity and a relative lack of real-world data. Future studies should use standardised measures of engagement, preferably assessed in a daily practice setting.

TRIAL REGISTERATION NUMBER

The protocol was registered on PROSPERO (CRD42021267936).

The Use of Mobile Health Apps in Clinical Practice Remains Challenging

According to several international recommendations, disease activity should be regularly monitored with validated outcome measures in patients with axial spondyloarthritis (axSpA), and therapy should be adapted accordingly.^1-3 Increasingly, healthcare providers are encouraged to also use patient-reported outcomes (PROs) for this purpose, to capture valuable data from the patient's perspective.
