Background: Allogeneic bone marrow transplantation (BMT) may be a curative treatment for patients with rheumatoid arthritis (RA), but it has serious risks, including death. It is uncertain whether patients would accept the risks and benefits of BMT and participate in clinical trials. We conducted a discrete choice experiment (DCE) to quantify risk tolerance and benefit-risk trade-offs to inform the design of a clinical trial for BMT.

- The objective of the study is to create updated treatment guidelines for managing axial spondyloarthritis (axSpA) in Canada.
- The recommendations were developed by a diverse panel through a careful process, using existing guidelines and ensuring they fit within the Canadian context, while also considering health equity.
- A total of fifty-six recommendations were made covering various aspects of axSpA management, including treatment for different stages of the disease and considerations for monitoring and ethics, and these guidelines will be continually updated as new information emerges.
Introduction: Rheumatoid arthritis (RA) is commonly characterized by joint space narrowing. High-resolution peripheral quantitative computed tomography (HR-pQCT) provides unparalleled visualization and quantification of joint space in extremity joints commonly affected by RA, such as the 2nd and 3rd metacarpophalangeal joints. However, age, sex, and obesity can also influence joint space narrowing.

Methods: We used the Google search engine (last search March 2023) using the terms "rheumatoid arthritis" and "flare management." Additional searches targeted major arthritis organizations, as well as regional, national, and international resources.
Objective: Patients with rheumatoid arthritis (RA) may need to access rheumatology care between scheduled visits. WelTel is a virtual care platform that supports secure two-way text-messaging between patients and their health care team. The objective of the present study was to explore perspectives and experiences of health care providers (HCPs) and patients related to the use of WelTel as an adjunct to routine care.

Our objective was to investigate the influence of different patient eligibility characteristics on the number of potentially deferred visits to inform future implementation of a PIFU strategy.
Methods: We conducted a retrospective chart review of 7 rheumatologists' practices at 2 university-based clinics between March 1, 2021, and February 28, 2022.
Objective: To examine the association between rheumatologist access, early treatment, and ongoing care of older-onset rheumatoid arthritis (RA) and healthcare utilization and costs following diagnosis.
Methods: We analyzed data from a population-based inception cohort of individuals aged > 65 years with RA in Ontario, Canada, diagnosed between 2002 and 2014 with follow-up to 2019. We assessed 4 performance measures in the first 4 years following diagnosis, including access to rheumatology care, yearly follow-up, timely treatment, and ongoing treatment with a disease-modifying antirheumatic drug.
Objective: To understand how people with chronic immune-mediated inflammatory diseases (IMIDs) trade off the benefits and risks of coronavirus disease 2019 (COVID-19) vaccine options.
Methods: We conducted an online discrete-choice experiment in people with IMIDs to quantify the relative importance (RI) of attributes relevant to COVID-19 vaccination. Participants were recruited between May and August 2021 through patient groups and clinics in Canada, and completed 10 choices where they selected 1 of 2 hypothetical vaccine options or no vaccine.
Objectives: Having previously shown similar clinical outcomes, this study compared the healthcare resource utilization and direct costs in stable patients with RA followed in the nurse-led care (NLC) and rheumatologist-led care (RLC) models.
Methods: Previously collected clinical data were linked to data on practitioner claims, ambulatory care, and hospital discharges. Assessed resources included physician visits; emergency department (ED) visits; hospital admissions, and disease-modifying anti-rheumatic drugs (DMARDs).
Objective: To determine whether there were improvements in rheumatology care for rheumatoid arthritis (RA) between 2002 and 2019 in Ontario, Canada, and to evaluate the impact of rheumatologist regional supply on access.
Methods: We conducted a population-based retrospective study of all individuals diagnosed with RA between January 1, 2002 and December 31, 2019. Performance measures evaluated were: (i) percentage of RA patients seen by a rheumatologist within one year of diagnosis; and (ii) percentage of individuals with RA aged 66 years and older (whose prescription drugs are publicly funded) dispensed a disease modifying anti-rheumatic drug (DMARD) within 30 days after initial rheumatologist visit.
Objective: The study objective was to assess adherence to system-level performance measures measuring retention in rheumatology care and disease modifying anti-rheumatic drug (DMARD) treatment in rheumatoid arthritis (RA).
Methods: We used a validated health administrative data case definition to identify individuals with RA in Ontario, Canada, between 2002 and 2014 who had at least 5 years of potential follow-up prior to 2019. During the first 5 years following diagnosis, we assessed whether patients were seen by a rheumatologist yearly and the proportion dispensed a DMARD yearly (in those aged ≥66 for whom medication data were available).
Objectives: The Rheumatoid Arthritis (RA) Quality of Care Survey (RAQCS) was developed to measure care quality according to a previously developed national RA quality improvement framework.
Methods: The development of the RAQCS occurred over 3 phases. First, the survey was developed by a team of healthcare providers, researchers, and two patient partners based on the existing national quality framework's 21 performance measures (PMs) and strategic objectives.
Objective: To compare clinical characteristics and treatment of patients with rheumatoid arthritis (RA) across 4 Canadian cohorts.
Methods: The 4 longitudinal cohorts included the following: the Canadian Early Arthritis Cohort (CATCH; n = 2878), Ontario Best Practices Research Initiative (OBRI; n = 3734), RHUMADATA (Quebec, n = 2890), and the Rheum4U Precision Health Registry (Calgary, Alberta, n = 709). Data were from cohort inception (range 1998-2016) to 2020.
Introduction: This pragmatic non-inferiority study assessed quality of care within a nurse-led care (NLC) model for stable patients with rheumatoid arthritis (RA) compared to the traditional rheumatologist-led care (RLC) model.
Methods: Data were collected through a chart review. Baseline demographic and clinical characteristics were compared using Chi-square test and t test.
Background: Current evidence suggests that many adolescents with juvenile idiopathic arthritis (JIA) do not successfully transfer to adult care, which can result in adverse health outcomes. Although a growing number of clinical programs have been designed to support healthcare transition, there is a lack of psychometrically sound instruments to evaluate their impact on development of transition-related knowledge and skills in youth with JIA. The purpose of this study was to develop and validate RACER (Readiness for Adult Care in Rheumatology), a self-administered instrument designed to measure stages of readiness for key transition-related skills in adolescents with JIA.

To address the goal of timely and equitable access to rheumatoid arthritis (RA) care, health planners require information at the regional and local level to determine the RA prevalence and the associated health care needs.
Methods: Using Alberta Health administrative databases, we identified RA-prevalent cases (April 1, 2015-March 31, 2016) on the basis of a validated case definition.
Objective: Decision aids are being developed to support guideline-based rheumatology care in Canada. The study objective was to identify barriers to decision aid use in rheumatoid arthritis (RA) within a behavior change model to inform an implementation strategy.
Methods: Perspectives from Canadian health care providers (HCPs) and patients living with RA were obtained on an early RA decision aid and on perceived facilitators and barriers to decision aid implementation.
Objectives: To obtain stakeholder perspectives to inform the development and implementation of a rheumatoid arthritis (RA) healthcare quality measurement framework.
Design: Qualitative study using thematic analysis of focus groups and interviews.
Setting: Arthritis stakeholders from across Canada including healthcare providers, persons living with RA, clinic managers and policy leaders were recruited for the focus groups and interviews.
Objective: The aim of this study was to develop a patient-centered quality measurement framework to address a predefined vision statement and 7 strategic objectives for rheumatoid arthritis (RA) care that was developed in prior qualitative work with arthritis stakeholders.
Methods: One hundred forty-seven RA-related performance measures (PMs) were identified from a systematic review. A candidate list of 26 PMs meeting predefined criteria and addressing the strategic objectives previously defined was then assessed during a 3-round (R) modified Delphi.
Objective: To elucidate the essential elements of high-quality rheumatoid arthritis (RA) care in order to develop a vision statement and a set of strategic objectives for a national RA quality framework.
Methods: Focus groups and interviews were conducted by experienced qualitative researchers using a semistructured interview or focus group guide with healthcare professionals, patients, clinic managers, healthcare leaders, and policy makers to obtain their perspectives on elements essential to RA care. Purposive sampling provided representation of stakeholder types and regions.
Introduction: In collaboration with the Alberta Medical Association's Physician Learning Program we developed individualized physician reports and held a group feedback session on rheumatoid arthritis (RA) performance measures (PM) to facilitate treat-to-target (T2T) strategies and evaluated physician experiences with this process.
Methods: 5 PMs addressing T2T concepts from an established Canadian quality framework were operationalized for physician practice reports at 2 university-affiliated rheumatology clinics. Rheum4U, a quality improvement and research platform, was the data source.
Objective: We evaluated 4 national rheumatoid arthritis (RA) system-level performance measures (PM) in Alberta, Canada.
Methods: Incident and prevalent RA cases ≥ 16 years of age since 2002 were identified using a validated case definition applied in provincial administrative data. Performance was ascertained through analysis of health data between fiscal years 2012/13-2015/16.
Objective: The objective of the study was to estimate the incidence and prevalence of rheumatoid arthritis (RA) in Alberta using administrative health data.
Methods: We identified RA cases in patients 16 years and older by applying a national case definition to linked administrative health data (ie, hospital discharge abstract records, physician claims, and health insurance registry records) using a unique personal identifier. Incidence and prevalence are reported for the 2015-2016 fiscal year and a trend analysis from 2011-2012 to 2015-2016.
