Objective: The National Institute of Health and Care Excellence (NICE) criteria for osteoarthritis (OA) obviate the need for physical exam or imaging, and their use may improve timely diagnosis of OA. However, they have not been validated.

Methods: Within a larger study of individuals with type 2 diabetes, participants with and without self-reported knee pain underwent assessment of the NICE criteria for knee OA by questionnaire (index test), and clinical evaluation for established or possible knee OA by a rheumatologist (reference standard).

Objective: To generate a list of candidate items potentially useful for discriminating individuals with Early-stage Symptomatic Knee Osteoarthritis (EsSKOA) from those with other conditions and from established osteoarthritis (OA), and to reduce this list based on expert consensus.

Design: We conducted a three-round online international modified Delphi exercise with OA clinicians and researchers ("OA experts"). In Round 1, participants reviewed 84 candidate items and nominated additional item(s) potentially useful for EsSKOA classification; those nominated by ≥3 participants were added.

Objective: To quantify the effectiveness and safety of intra-articular interventions for knee and hip osteoarthritis (OA) through a systematic review and Bayesian random-effects network meta-analysis.

Design: We searched CENTRAL and regulatory agency websites (inception-2023) for large, English-language, randomized controlled trials (RCTs) (≥100 patients/group) examining any intra-articular intervention.

Primary Outcome: pain intensity.

Article Synopsis
  • The study ranks patient-reported outcome measures (PROMs) for pain in osteoarthritis, focusing on their ability to distinguish effective treatments from placebos.
  • Analysis included 135 trials with over 57,000 participants, standardizing treatment effects across multiple PROMs on a 0-100 scale.
  • The findings suggest "pain overall" is the most sensitive PROM, outperforming others like WOMAC pain, helping guide future clinical trials and data analysis in osteoarthritis research.

Objective: Difficulty walking is a primary reason that individuals with knee osteoarthritis (OA) seek care. We examined the change in self-reported difficulty walking after participating in the Good Life With Osteoarthritis in Denmark (GLA:D) 8-week education and exercise program and assessed patient factors associated with improvement in difficulty walking.

Methods: This was a registry-based cohort study of individuals in Denmark with knee OA who enrolled in GLA:D.

Objective: We sought to evaluate urate-lowering therapy (ULT) adherence and treatment-to-target (T2T) serum uric acid (SUA) levels among older adults with gout starting ULT.

Methods: We performed a population-based retrospective cohort study in Ontario, Canada in patients with gout aged ≥66 years newly dispensed ULT between 2010 and 2019. We defined successful T2T as patients having SUA levels <360 μmol/L (6 mg/dL) within 12 months after ULT dispensation.

Background: Effective mentorship is an important contributor to academic success. Given the critical role of leadership in fostering mentorship, this study sought to explore the perspectives of departmental leadership regarding 1) current departmental mentorship processes; and 2) crucial components of a mentorship program that would enhance the effectiveness of mentorship.

Methods: Department Division Directors (DDDs), Vice-Chairs, and Mentorship Facilitators from the Department of Medicine at the University of Toronto Temerty Faculty of Medicine were interviewed between April and December 2021 using a semi-structured guide.

Background: Immigrants and refugees face unique challenges navigating the health care system to manage severe arthritis, because of unfamiliarity, lack of awareness of surgical options, or access. The purpose of this study was to assess total knee arthroplasty (TKA) uptake, surgical outcomes, and hospital utilization among immigrants and refugees compared with Canadian-born patients.

Methods: We included all adults undergoing primary TKA from January 2011 to December 2020 in Ontario.

Background: Various studies have demonstrated gender disparities in workplace settings and the need for further intervention. This study identifies and examines evidence from randomized controlled trials (RCTs) on interventions examining gender equity in workplace or volunteer settings. An additional aim was to determine whether interventions considered intersection of gender and other variables, including PROGRESS-Plus equity variables (e.

Article Synopsis
  • Obesity is a significant issue for osteoarthritis (OA) research, but relying on body mass index (BMI) has limitations, such as not differentiating between fat and muscle mass.
  • The use of BMI can contribute to weight bias in clinical settings and affect access to OA treatments, leading to health disparities.
  • Future OA research should explore alternative obesity measures and address weight stigma to improve health outcomes for affected individuals.

Objective: As part of the first phase of the OARSI Early-stage Symptomatic Knee Osteoarthritis (EsSKOA) initiative, we explored the first symptoms and experiences recalled by individuals with knee osteoarthritis (OA).

Design: This qualitative study, informed by qualitative description, was a secondary analysis of focus groups (n ​= ​17 groups) and one-on-one interviews (n ​= ​3) conducted in 91 individuals living with knee OA as part of an international study to better understand the OA pain experience. In each focus group or interview, participants were asked to describe their first symptoms of knee OA.

Objectives: The design, analysis, and interpretation of cluster randomized clinical trials (RCTs) require accounting for potential correlation of observations on individuals within the same cluster. Reporting of observed intracluster correlation coefficients (ICCs) in cluster RCTs, as recommended by Consolidated Standards of Reporting Trials (CONSORT), facilitates sample size calculation of future cluster RCTs and understanding of the trial statistical power. Our objective was to summarize observed ICCs in osteoarthritis (OA) cluster RCTs.

Objective: To assess the proportion of, and factors associated with, older adults with gout receiving a serum urate (SUA) test after starting urate-lowering therapy (ULT).

Methods: We performed a population-based retrospective cohort study in Ontario, Canada in patients ages ≥66 years with gout, newly dispensed ULT between 2010 and 2019. We characterized patients with SUA testing within 6 and 12 months after ULT dispensation.

Background: Early-stage knee osteoarthritis (KOA) classification criteria will enable consistent identification and trial recruitment of individuals with knee osteoarthritis (OA) at an earlier stage of the disease when interventions may be more effective. Toward this goal, we identified how early-stage KOA has been defined in the literature.

Methods: We performed a scoping literature review in PubMed, EMBASE, Cochrane, and Web of Science, including human studies where early-stage KOA was included as a study population or outcome.

Objectives: One-fifth of total knee arthroplasty (TKA) recipients experience a suboptimal outcome. Incorporation of patients' preferences in TKA assessment may improve outcomes. We determined the discriminant ability of preoperative measures of TKA need, readiness/willingness and expectations for a good TKA outcome.

Background: Symptomatic knee osteoarthritis (OA) commonly co-occurs in people with type 2 diabetes (T2DM) and increases the risk for diabetes complications, yet uptake of evidence-based treatment is low. We combined theory, stakeholder involvement and existing evidence to develop a multifaceted intervention to improve OA care in persons with T2DM. This was done in partnership with Arthritis Society Canada to leverage the existing infrastructure and provincial funding for community arthritis care.

Objective: To determine if continuity of rheumatology care influences rates of emergency department (ED) visits and hospitalizations in patients with rheumatoid arthritis (RA).

Methods: A closed inception cohort of patients with RA diagnosed between 2000 and 2009 were followed until December 31, 2019. During the first 5 years following diagnosis, we categorized patients into 3 rheumatology care continuity groups (high, intermediate, and not retained in rheumatology care).
