Methods: We distributed an electronic survey to International Myositis Assessment and Clinical Studies (IMACS) members to identify new items.

Organizational Climate and Decision Aid Sustainability in Lupus Care: Mixed Methods Study.

Background: Digital decision aids (DAs) are increasingly used in health care to support shared decision-making and promote patient engagement. In the context of systemic lupus erythematosus (SLE), a complex autoimmune disease characterized by diverse symptoms and uncertain prognoses, DAs offer guidance to patients in navigating treatment risks and benefits. Although numerous studies have examined the initial implementation of evidence-based tools, there is limited evidence on the organizational factors that influence their long-term sustainability in clinical practice.

GRADE Concept Paper 9: Rationale and process for creating a GRADE Ontology.

Context: As the rate of research production accelerates, the ability to efficiently and unambiguously communicate judgements relating to the synthesis, evaluation, and use of scientific information becomes paramount.

Perspective: Scientific information can be viewed as a "layered infrastructure" of data, evidence, knowledge, and use. The GRADE approach serves as a de facto data standard in this infrastructure, reducing ambiguity in claims to knowledge (in the form of judgements of certainty in the evidence when answering research questions) and level of commitment to possible solutions to problems (in the form of strength of recommendations for interventions).

Where, how, and how much? A multicenter cohort study of the relationship between lupus decision aid modality, place of administration, interruption and viewing completeness and patient-reported outcomes.

Objective: We assessed whether shared decision-making (SDM), and patient acceptability, feasibility, and overall satisfaction with a computerized patient decision aid (PtDA) for patients with systemic lupus erythematosus (SLE), differs by PtDA setting, modality, and the viewing experience.

Methods: Patients with SLE were invited to view a self-administered computerized SLE PtDA during regular clinic visits at 15 rheumatology clinics in an implementation trial. Patients completed a survey that included SDM measures including the decision-conflict (DCS), preparation for decision-making (PDM), and CollaboRATE scales; perceived patient acceptability, feasibility, and satisfaction.

Manual Validation of an Algorithm for Identifying Osteoarthritis within the Centralized Interactive Phenomics Resource of the Million Veteran Program.

Objective: This study aimed to validate an osteoarthritis (OA) phenotyping algorithm within the Million Veteran Program (MVP) using the United States (US) Department of Veterans Affairs (VA) Centralized Interactive Phenomics Resource (CIPHER).

Methods: A random sample of 213 veterans was analyzed sing ICD-9-CM/ICD-10-CM codes from a previously published algorithm (PMID:29559693). OA cases required two OA codes at least 30 days apart, while controls were excluded based on codes for conditions more common in OA patients, such as chondrocalcinosis and crystal arthropathies.

Testing for Causal Association between Serum Urate, Gout, and Prostatic Cancer in European Males.

Objective: To conduct a two-sample MR study including only men to test for a causal relationship between serum urate (SU) and gout and prostate cancer.

Methods: We used GWAS for SU, gout, and prostate cancer to generate exposure instrumental variables (IV) associated with gout and urate. We used 20 single nucleotide polymorphisms (SNPs) associated with gout but not urate for an IV representing the non-hyperuricemia (inflammatory) compartment of gout and we used four SNPs from loci containing urate transporter genes for an IV representing urate levels.

Hospital and patient factors predict length of stay in patients with osteoarthritis undergoing total primary hip replacement.

Objectives: Over 450,000 primary total hip arthroplasties (THA) are performed each year in the US, with osteoarthritis (OA) as the major indication for primary THA.

Time required to implement a computerized patient decision aid for lupus in outpatient visits.

Background: Patient decision aids have the potential to lower decision conflict for patients and to improve patient-physician communication. However, uptake of decision aids has been poor, in part because the time required to incorporate these into clinical practice is not well understood.

Objective: To estimate the time required for a rheumatology clinic to implement a validated decision aid for patients with lupus.

Translational genomics of osteoarthritis in 1,962,069 individuals.

Osteoarthritis is the third most rapidly growing health condition associated with disability, after dementia and diabetes. By 2050, the total number of patients with osteoarthritis is estimated to reach 1 billion worldwide. As no disease-modifying treatments exist for osteoarthritis, a better understanding of disease aetiopathology is urgently needed.
