Young people's perspectives on patient-reported outcome measures in inflammatory arthritis: results of a multicentre European qualitative study from a EULAR task force

Current Validated Clinical and Patient Reported Disease Outcome Measures in Juvenile Idiopathic Arthritis

Juvenile idiopathic arthritis (JIA) is a common chronic illness in childhood and comprises seven categories based on the International League of Associations for Rheumatology (ILAR) criteria. Accurate assessment and measurement of the clinical, functional, and quality of life outcomes of patients with JIA are paramount for understanding the disease course and formulating effective treatment strategies. Interest in the development and use of outcome measurements specifically focused on rheumatologic conditions has greatly expanded over the last two decades, adding to and improving upon the established disease measures. Furthermore, many of these measures have been validated using the widely accepted Outcome Measures in Rheumatology (OMERACT) core principles of instrument validation, allowing researchers and clinicians to gain confidence in these tools. This review summarizes the current validated disease outcome measures in JIA, including clinical, imaging, patient-reported, and functional outcome measurement tools, and highlights ongoing work that continues to refine and improve upon the available tools. The clinical disease outcome measures discussed in this review include physician global assessment (PhGA), American College of Rheumatology (ACR, Wallace) criteria for clinical inactive disease and clinical remission, juvenile arthritis disease activity scores (JADAS), juvenile spondyloarthritis disease activity index (JSPaDA), juvenile arthritis damage index (JADAI), and the ACR pediatric response scores. The imaging outcome measures discussed include the Dijkstra composite scores, childhood arthritis radiographic score of the hip (CARSH), and Poznanski Score. The patient-reported disease outcome measures discussed include patient global assessment (PtGA), patient-reported outcome measurement information system for JIA (PROMIS), juvenile arthritis parent/child centered disease assessment index (JAPAI, JACAI), juvenile arthritis multidimensional assessment report (JAMAR), and the Pediatric quality of life inventory rheumatology module (PedsQL). The functional outcome tools discussed include the Childhood Health Assessment Questionnaire (CHAQ), juvenile arthritis functionality scale and index (JAFS and JASI), and Juvenile Arthritis Functional Assessment Report and Scale (JAFAS and JAFAR).

Stakeholder outcome prioritization in the Biologic Abatement and Capturing Kids' Outcomes and Flare Frequency in Juvenile Spondyloarthritis (BACK-OFF JSpA) trial

BACKGROUND

The Biologic Abatement and Capturing Kids' Outcomes and Flare Frequency in Juvenile Spondyloarthritis (BACK-OFF JSpA) study is a randomized, pragmatic trial investigating different tumour necrosis factor inhibitor de-escalation strategies for children with sustained inactive disease. In this project, we elicited concept rankings that aided in the selection of the patient-reported outcome (PRO) measures that should be examined as part of the BACK-OFF JSpA trial.

METHODS

We conducted a discrete choice experiment to evaluate individuals' preferences regarding PROs. Stakeholders assessed a discrete list of 21 outcome concepts, each of which had a Patient-Reported Outcome Measurement Information System (PROMIS) measure associated with it. PROMIS measures are self- or proxy-reported instruments that are universally applicable to the general population and all chronic conditions. Stakeholders were required to make choices instead of expressing the strength of a preference.

RESULTS

Fourteen caregivers, 12 patients (9-22 years old), 16 rheumatologists and three executives from health insurance companies completed the exercise, which took approximately 10 min. The discrete choice experiment resulted in an estimate of the relative importance of each outcome and rank. All stakeholder groups agreed that the primary PRO should be 'Pain Interference', a measure that evaluates the effect of pain on a child's everyday activities, including its impact on social, emotional, mental and physical functioning. Patients and caregivers were mostly aligned in their top priorities, with patients valuing physical health (50% of the top 10) whereas caregivers were more interested in mental health (60% of the top 10). Rheumatologists and health insurance executives were most interested in physical health outcomes, which were ranked 80% and 60% of their top 10 PROs, respectively. Overall, the patients had the most diverse set of prioritized outcomes, including at least one of each category in their top 10 rank order of importance. Patients were also the only stakeholders to prioritize 'social' health.

CONCLUSIONS

Patients and caregivers were mostly aligned in their outcome priority rankings. The rank-order list directly informed the creation of a profile of PRO measures for our upcoming trial.

The Your Rheum story: involvement of young people in rheumatology research

Until recently, young people too often fell into the gaps between services due to restrictive age criteria. Furthermore, their voice was too infrequently heard or was represented by proxies in the form of their caregivers or by adults recalling their youth. The lack of young person involvement in adolescent health research including the arena of paediatric and adolescent chronic disease has been highlighted in current literature. However, the involvement of young people at all stages of health research, from priority setting through to dissemination, is widely advocated. Furthermore, such involvement is considered to be important ethically and, most important of all, has been called for by young people themselves. Young people have clear views about research and these views potentially enhance our understanding of how young people form opinions about research. These opinions in turn informs researchers how to best engage young people (including recruitment and retention) in research. Such involvement of young people ensures that research questions, project methodologies and/or interventions are truly resonant with their lives. This paper describes the development of a national youth advisory group in UK rheumatology, an important addition to the evolving evidence base to support the involvement of young people in rheumatology research. The paper is written with two young people who are members of this group, providing them with an opportunity to learn more about a key component of research—writing papers for publication.

An electronic patient-reported outcome created based on my needs is worth using: an explorative qualitative study investigating young people's opinions for a health assessment tool

BACKGROUND

Young people in different healthcare settings are positive about using electronic patient-reported outcomes (ePROs), which are meant to increase the effectiveness and safety of interventions from the patient's perspective. Sweden offers free healthcare to young people aged 12-25 years at 275 youth health clinics (YHCs), whose goals are to strengthen young people and promote sexual, physical, and mental health. YHCs need effective ways to identify the overall picture of young people's health and health-related problems. To our knowledge, there is no ePRO for YHCs that provides an overview of young people's health from several health perspectives. The aim of this study was to explore young people's view on content and design of an ePRO to provide an overview of their health and health related problems when visiting a YHC, and their opinion on what healthcare needs to consider when using the ePRO. This was an explorative qualitative study. The participants were included from five YHCs, in different socioeconomic areas in central Sweden. Fifteen participants were included: 10 girls, three boys, and two non-binary participants with an age range of 16-22 years. Data were collected using a semi-structured interview guide and individual interviews, and inductive content analysis was performed.

RESULTS

One main theme, "ePRO created based on my needs is worth using" and two sub-themes, "Appealing content and design" and "Trusting healthcare", emerged. The participants wanted that an ePRO should include overall questions about mental-, physical-, and sexual health and social support. Participants also believed the ePRO must disclose the risks of self-harm or suicide. The participants noted the importance of emotional and digital security when using the ePRO and having a confidential conversation with a healthcare provider. To share health information means to trust to gain health.

CONCLUSIONS

The study participants' views on content and design can form the basis for designing an ePRO for young people. Their thoughts on safety and treatment in healthcare can be considered in the development process. This study is the starting point for developing an ePRO for young people at YHCs.

Economic impact of Juvenile Idiopathic Arthritis: a systematic review

BACKGROUND

Juvenile Idiopathic Arthritis (JIA) requires complex care that generate elevated costs, which results in a high economic impact for the family. The aim of this systematic review was to collect and cluster the information currently available on healthcare costs associated with JIA after the introduction of biological therapies.

METHODS

We comprehensively searched in MEDLINE, EMBASE, Web of Science, Scopus, and Cochrane Databases for studies from January 2000 to March 2021. Reviewers working independently and in duplicate appraised the quality and included primary studies that report total, direct and/or indirect costs related to JIA for at least one year. The costs were converted to United States dollars and an inflationary adjustment was made.

RESULTS

We found 18 eligible studies including data from 6,540 patients. Total costs were reported in 10 articles, ranging from $310 USD to $44,832 USD annually. Direct costs were reported in 16 articles ($193 USD to $32,446 USD), showing a proportion of 55 to 98 % of total costs. Those costs were mostly related to medications and medical appointments. Six studies reported indirect costs ($117 USD to $12,385 USD). Four studies reported costs according to JIA category observing the highest in polyarticular JIA. Total and direct costs increased up to three times after biological therapy initiation. A high risk of reporting bias and inconsistency of the methodology used were found.

CONCLUSION

The costs of JIA are substantial, and the highest are derived from medication and medical appointments. Indirect costs of JIA are underrepresented in costs analysis.

Back to Basics: Prioritizing Communication as a Key Instrument in Managing Rheumatoid Arthritis

Patients with rheumatoid arthritis (RA) have come to experience a tremendous increase in therapeutic options with disease-modifying antirheumatic drugs (DMARDs).¹ After decades of dissatisfying drug therapy results with conventional synthetic DMARDs (csDMARDs) only, the introduction of the first tumor necrosis factor inhibitors in the late 1990s has revolutionized RA treatment.².

The value of the patient global health assessment in polyarticular juvenile idiopathic arthritis: a nested cohort study

Objective

The objectives were: 1) to explore the discordance between the Patient Global Health Assessment (PtGA) scores, the Physician Global Health Assessment (PhGA) scores, and Pain scores; and 2) to explore whether the PtGA during disease remission is associated with future disease flare in pJIA.

Methods

Data from an NIH funded clinical trial (NCT00792233) evaluating flare were used (N = 137). PtGA, PhGA, and Pain scores were assessed. Flare was defined as any active arthritis. Spearman’s correlation coefficients were calculated, and multivariable logistic regression was performed.

Results

122 patients had records of flare status, of which 63 developed flare, and 42 of these patients had a visit immediately prior to flare. For study subjects with a visit immediately prior to flare, the PtGA, pain scores, and PhGA all increased at time of flare. For every unit increase in PtGA and Pain scores, there was a 9% and 23% higher odds of developing flare, respectively (p = 0.76, p = 0.40). For every unit increase in the PhGA score, there was a substantially lower odds of developing flare (p = 0.05).

Conclusion

Our results demonstrate that the PtGA and Pain scores are strongly correlated with each other and increased at the visit prior to flare, while the PhGA scores are not. Further, the PtGA and Pain score have some predictive value for flare, while the PhGA does not. These findings highlight the value of patient input in medical care and decision-making, and support the development and use of more sophisticated PROs in the care of JIA patients.

Patient perceptions of outcome measures in chronic inflammatory demyelinating polyneuropathy: A study of the Inflammatory Rasch-built Overall Disability Scale

BACKGROUND

Patients' perceptions of outcome measures used in chronic inflammatory demyelinating polyneuropathy (CIDP) are unknown.

METHODS

We performed a cross-sectional evaluation of patient perceptions of the Inflammatory Rasch-built Overall Disability Scale (I-RODS) from 41 subjects with CIDP through a structured questionnaire. We assessed perceived hesitation to provide a response, item importance and relevance, understanding of specific items and factors affecting responses.

RESULTS

Hesitation to provide a categorical answer was reported by 20% of subjects or more, for 5/24 (20.8%) items. Uncertainty was most frequent for "travel by public transport" (22.4%) and "catch an object (e.g., ball)" (24%). Six of 24 (25%) items were perceived as unimportant to their disease by at least a third of participants. Items most commonly perceived as unimportant were "travel by public transport" in 53.7%, "catch an object (e.g., ball)" in 61% and "dance" in 65.9%. Several items were frequently perceived as irrelevant. These included "move a chair" (39%), "do the dishes" (46.3%), "catch an object (e.g., ball)" (61%), "travel by public transport" (68.3%) and "stand for hours" (82.9%). The understanding of multiple items such as "read a book", "sit on a toilet" and "take a shower" was found to be highly variable. Fatigue was perceived more commonly than mood (53.7% vs. 17.1%, p = 0.001), and more commonly in younger subjects (p = 0.037), as influencing responses to the I-RODS.

CONCLUSIONS

Patient-perceived uncertainty, unimportance, irrelevance and poor understanding of items, as well as fatigue and mood, impact on the value of the I-RODS. Greater emphasis on individualized disability assessments requires consideration in future.
