Background: By 2030, the global population of people older than 60 years is expected to be higher than the number of children under 10 years, resulting in major health and social care system implications worldwide. Without a supportive environment, whether social or built, diminished functional ability may arise in older people. Functional ability comprises an individual's intrinsic capacity and people's interaction with their environment enabling them to be and do what they value.

Rheumatology workforces are increasingly challenged by too few physicians in face of the growing burden of rheumatic and musculoskeletal diseases (RMDs). Rheumatology is one of the most frequent non-surgical specialty referrals and has the longest wait times for subspecialists. We used a population-based approach to describe changes in the rheumatology workforce, patient volumes and geographic variation in the supply of and access to rheumatologists, in Ontario, Canada, between 2000 and 2019, and projected changes in supply by 2030.

Article Synopsis
  • This study aimed to understand how patients with rheumatoid arthritis (RA) and clinicians interpret scores from PROMIS instruments used to measure pain interference and fatigue.
  • Researchers created patient scenarios to help identify symptom severity thresholds and what changes in scores are considered significant for treatment decisions.
  • Findings showed that patients typically set higher thresholds than clinicians for symptom severity and generally deemed a change of 5-10 points as meaningful, reflecting their personal experiences with RA and its impact on their daily lives.

Purpose: Patient decision-aids (PtDAs) help patients make informed treatment decisions incorporating their values. Health-related quality of life (HRQOL) is sometimes an outcome of PtDA effectiveness trials, but its suitability for this purpose is unclear. We sought to provide insights into this question by critically appraising how randomized controlled trials (RCTs) evaluating PtDA effectiveness measure and report HRQOL.

Plain English Summary: With the growing movement to engage patients in research, questions are being asked about who is engaging patients and how they are being engaged. Internationally, research groups are supporting and funding patient-oriented research studies that engage patients in the identification of research priorities and the design, conduct and uptake of research. As we move forward, we need to know what meaningful patient engagement looks like, how it benefits research and clinical practice, and what are the barriers to patient engagement?We conducted a review of the published literature looking for trials that report engaging patients in the research.

Background: Randomised controlled trials can provide evidence relevant to assessing the equity impact of an intervention, but such information is often poorly reported. We describe a conceptual framework to identify health equity-relevant randomised trials with the aim of improving the design and reporting of such trials.

Methods: An interdisciplinary and international research team engaged in an iterative consensus building process to develop and refine the conceptual framework via face-to-face meetings, teleconferences and email correspondence, including findings from a validation exercise whereby two independent reviewers used the emerging framework to classify a sample of randomised trials.
