Knowledge of and stated adherence to the 2020 ACR Guideline for Gout Management: Results of a survey of US rheumatologists.

OBJECTIVE: This report evaluates rheumatologists' stated adherence to and agreement with the 2020 American College of Rheumatology (ACR) Guideline for the Management of Gout. METHODS: A 57-item questionnaire was administered to US rheumatologists. Stated adherence scores were based on several guideline recommendations reported to be followed by rheumatologists in practice, whereas stated agreement scores were based on whether respondents always followed the recommendations. RESULTS: All 201 rheumatologists completed the questionnaire. The mean overall stated adherence score was 11.5 (maximum: 15), whereas the mean overall stated agreement score was 7.7 (maximum: 14). Less experienced rheumatologists (≤8 years; n=49) were likely to claim adherence to more individual ACR recommendations than those with more experience (>8 years; n=152; mean stated adherence score: 12.3 vs 11.3; P ≤ 0.05). Rheumatologists who claimed to see ≤75 patients with gout in 6 months (n=66) had a mean stated adherence score of 12.1 versus 11.2 for those who claimed to have seen >75 patients (P ≤ 0.05). Approximately 78% of rheumatologists claimed to follow the guideline for initiating urate-lowering therapy (ULT), and 89% were likely to prescribe allopurinol as a first-line ULT. Claimed adherence to recommendations for dosing was lower (febuxostat, 43%; allopurinol, 39%). Rheumatologists from academic settings were more likely to prescribe an interleukin-1 inhibitor for gout flares. CONCLUSION: The self-reported practice of the surveyed US rheumatologists was generally concordant with the 2020 ACR Guideline for the Management of Gout. However, there were gaps in guideline knowledge and stated adherence among rheumatologists, mainly concerning the dosing of treatment regimens.

Accuracy of Financial Disclosures in US-Based Rheumatology Journals.

OBJECTIVE: Transparency of disclosure in publication is necessary for readers to be aware of any potential conflicts of interest (PCOIs). Past studies of accuracy of disclosure in rheumatology journals have focused exclusively on clinical practice guidelines and not research works. We assessed discrepancy in reporting PCOIs in clinically oriented manuscripts published in the three top-ranked (by impact factor) US-based general rheumatology journals. METHODS: We reviewed disclosures provided by first, second, and last authors of 50 published clinically oriented articles in each of the three top-ranked general US rheumatology journals. For each author, we extracted payment reports from the Open Payments Database (OPD) related to consulting fees, honoraria, and speaker or faculty compensation. We defined a PCOI as a payment received from a company with an ongoing clinical trial or a medication on the market related to the manuscript's subject matter within the 36 months before the online publication date. We additionally analyzed each author individually to determine whether their reported disclosures matched PCOIs from the OPD. RESULTS: Of 150 articles analyzed, 101 included authors with PCOIs. Ninety-two of these 101 publications (92%) contained inaccurate (non- or under-) disclosures. Among 135 authors with PCOIs, 118 reported inaccurately (87%). All 14 articles that published clinical trial results (and all 23 of their qualifying authors) had disclosure inaccuracies. CONCLUSION: Inaccurate financial disclosure by authors remains an issue in clinically oriented research studies reported in top rheumatology journals. Improved community education and firmer expectations would permit readers to better assess any possible impact of PCOIs on publications.

Determinants of Achieving Serum Urate Goal with Treat-to-Target Urate-Lowering Therapy in Gout.

OBJECTIVE: Using trial data comparing treat-to-target allopurinol and febuxostat in gout, we examined participant characteristics associated with serum urate (SU) goal achievement. METHODS: Participants with gout and SU ≥6.8 mg/dL were randomized to allopurinol or febuxostat, titrated during weeks 0 to 24, and maintained weeks 25 to 48. Participants were considered to achieve SU goal if the mean SU from weeks 36, 42, and 48 was <6.0 mg/dL or <5 mg/dL if tophi were present. Possible determinants of treatment response were preselected and included sociodemographics, comorbidities, diuretic use, health-related quality of life (HRQoL), body mass index, and gout measures. Determinants of SU response were assessed using multivariable logistic regression with additional analyses to account for treatment adherence. RESULTS: Of 764 study participants completing week 48, 618 (81%) achieved SU goal. After multivariable adjustment, factors associated with a greater likelihood of SU goal achievement included older age (adjusted odds ratio [aOR] 1.40 per 10 years), higher education (aOR 2.02), and better HRQoL (aOR 1.17 per 0.1 unit). Factors associated with a lower odds of SU goal achievement included non-White race (aORs 0.32-0.47), higher baseline SU (aOR 0.83 per 1 mg/dL), presence of tophi (aOR 0.29), and the use of diuretics (aOR 0.52). Comorbidities including chronic kidney disease, hypertension, diabetes, and cardiovascular disease were not associated with SU goal achievement. Results were not meaningfully changed in analyses accounting for adherence. CONCLUSIONS: Several patient-level factors were predictive of SU goal achievement among patients with gout who received treat-to-target urate-lowering therapy (ULT). Approaches that accurately predict individual responses to treat-to-target ULT hold promise in facilitating personalized management and improving outcomes in patients with gout.

Major Adverse Cardiovascular Events After Colchicine Administration Before Percutaneous Coronary Intervention: Follow-Up of the Colchicine-PCI Trial.

Periprocedural inflammation is associated with major adverse cardiovascular events in patients who undergo percutaneous coronary intervention (PCI). In the contemporary era, 5% to 10% of patients develop restenosis, and in the acute coronary syndrome cohort, there remains a 20% major adverse cardiovascular events rate at 3 years, half of which are culprit-lesion related. In patients at risk of restenosis, colchicine has been shown to reduce restenosis when started within 24 hours of PCI and continued for 6 months thereafter, compared with placebo. The Colchicine-PCI trial, which randomized patients to a 1-time loading dose of colchicine or placebo 1 to 2 hours before PCI, showed a dampening of the inflammatory response to PCI but no difference in postprocedural myocardial injury. On mean follow-up of 3.3 years, the incidence of major adverse cardiovascular events did not differ between colchicine and placebo groups (32.5% vs 34.9%; hazard ratio 0.95 [0.68 to 1.34]).

Arthrocentesis and soft tissue aspiration and injection.

Accessing a joint with a needle (arthrocentesis) to extract synovial fluid is a skill intrinsic to the rheumatologist's praxis. Joint aspirations are essential for diagnosing or excluding septic joints, are the gold standard for diagnosing acute crystal arthritis, and can provide valuable information about the nature of other forms of arthritis. In appropriate settings, injecting medications into joints can provide rapid, temporary, or even prolonged relief of pain and swelling and can provide a window of relief until other treatment modalities (anti-inflammatories, immunomodulators, and physical therapy) can enforce durable responses. Soft tissue aspirations (e.g., of bursae) and soft tissue injections (of bursae, tendons, trigger points, and areas of nerve compression) can provide similar relief, earning the practitioner the gratitude of the patient. Here, we provide a primary on joint and soft tissue aspiration and injection, including indications for and against procedures, preparing for procedures, and approaches to specific musculoskeletal structures.

Interleukin-1ß inhibitors for the management of acute gout flares: a systematic literature review.

OBJECTIVES: The objective of this systematic review was to assess the effects of interleukin-1ß (IL-1ß) inhibitors on gout flares. METHODS: Studies published between 2011 and 2022 that evaluated the effects of IL-1ß inhibitors in adult patients experiencing gout flares were eligible for inclusion. Outcomes including pain, frequency and intensity of gout flares, inflammation, and safety were assessed. Five electronic databases (Pubmed/Medline, Embase, Biosis/Ovid, Web of Science and Cochrane Library) were searched. Two independent reviewers performed study screening, data extraction and risk of bias assessments (Cochrane Risk of Bias Tool 2 for randomised controlled trials [RCTs] and Downs and Black for non-RCTs). Data are reported as a narrative synthesis. RESULTS: Fourteen studies (10 RCTs) met the inclusion criteria, with canakinumab, anakinra, and rilonacept being the three included IL-1ß inhibitors. A total of 4367 patients with a history of gout were included from the 14 studies (N = 3446, RCTs; N = 159, retrospective studies [with a history of gout]; N = 762, post hoc analysis [with a history of gout]). In the RCTs, canakinumab and rilonacept were reported to have a better response compared to an active comparator for resolving pain, while anakinra appeared to be not inferior to an active comparator for resolving pain. Furthermore, canakinumab and rilonacept reduced the frequency of gout flares compared to the comparators. All three medications were mostly well-tolerated compared to their comparators. CONCLUSION: IL-1ß inhibitors may be a beneficial and safe medication for patients experiencing gout flares for whom current standard therapies are unsuitable.

Narrative Review: Peripheral Arterial Disease in Patients with Hyperuricemia and Gout.

PURPOSE OF REVIEW: To discuss what is currently known about the association and potential mechanistic interactions of hyperuricemia and gout with peripheral arterial disease (PAD). RECENT FINDINGS: Gout patients are at increased risk for coronary artery disease, but less is known about their risk for PAD. Studies suggest that the presence of gout and hyperuricemia are associated with PAD independent of known established risk factors. Moreover, higher SU was found to be associated with greater odds of having PAD and was independently associated with decreased absolute claudication distance. Urate's role in free radical formation, platelet aggregation, vascular smooth muscle proliferation, and impaired endothelial vasodilation may promote atherosclerotic progression. Studies suggest that patients with hyperuricemia or gout are at higher risk for developing PAD. Evidence is stronger for the relationship between elevated SU and PAD than for gout and PAD, but more data is needed. Whether elevated SU serves as a marker or cause of PAD remains to be investigated.

Lowering and Raising Serum Urate Levels: Off-Label Effects of Commonly Used Medications.

Drug-induced hyperuricemia and gout present an increasingly prevalent problem in clinical practice. Herein, we review the urate-lowering or urate-raising effects of commonly used agents. We performed a PubMed search using the terms gout, urate, and medication, along with the specific agents/classes described herein. Reports were reviewed until 2022, and original studies were considered if they primarily or secondarily reported the effects of 1 or more drugs on serum urate level. Previous reviews were assessed for references to additional studies that described urate-altering effects of medications. Urate-changing drugs are summarized regarding their magnitude of effect, mechanism of action, and clinical significance. Potentially urate-lowering drugs include angiotensin II receptor blockers, calcium channel blockers, high-dose aspirin and salicylates, some nonsalicylate nonsteroidal anti-inflammatory drugs, angiotensin-converting enzyme inhibitors, sodium-glucose cotransporter 2 inhibitors, statins, and fenofibrate. Potentially urate-increasing drugs discussed include diuretics, ß-blockers, insulin, pyrazinamide, ethambutol, calcineurin inhibitors, low-dose aspirin, testosterone, and lactate. In patients who have or are at risk for hyperuricemia or gout, an increased awareness of drugs that affect serum urate level may allow for prescribing that effectively treats the indicated problem while minimizing adverse effects on hyperuricemia and gout.

Monosodium urate deposition in the lumbosacral spine of patients with gout compared with non-gout controls: A dual-energy CT study.

BACKGROUND: Gout is the most common cause of inflammatory arthritis in adults. Gout predominantly affects the peripheral joints, but an increasing number of published cases report gout affecting the spine. We used dual-energy CT (DECT) to assess the prevalence of monosodium urate (MSU) deposition in the spine of gout patients compared to controls, and to investigate whether gout or spinal MSU deposition is associated with low back pain. METHODS: 25 controls and 50 gout subjects (non-tophaceous and tophaceous) were enrolled. Demographics, gout history, Aberdeen back pain score, serum urate (sU), ESR and CRP were ascertained. Subjects underwent DECT of the lumbosacral spine, which was analyzed using manufacturer's default post-processing algorithm for MSU deposition as well as a maximally-specific algorithm to exclude potential artifact. FINDINGS: 72 subjects were analyzed (25 control, 47 gout). Gout subjects had greater BMI, serum creatinine, sU, CRP, and ESR versus controls. Using the default algorithm, MSU-coded volumes in the lumbosacral spines were significantly higher among the gout subjects vs controls (p = 0.018). 34% of gout subjects vs 4% of controls had spinal MSU-coded deposition (p = 0.0036). Applying the maximally-specific DECT post-processing algorithm, 18% of gout patients vs 0% of controls continued to demonstrate spinal MSU-coded deposition (p = 0.04). Non-tophaceous and tophaceous subjects did not differ in spinal MSU-coded deposition or sU. Gout patients had more back pain than controls. INTERPRETATION: A significant subpopulation of gout patients have spinal MSU-coded lesions. Default and maximally-specific MSU post-processing algorithms yielded different absolute MSU-coded volumes, but similar patterns of results. Gout patients had more back pain than controls. Spinal MSU deposition in gout patients may have implications for clinical picture and treatment.

Comparative Effectiveness of Allopurinol and Febuxostat in Gout Management.

BACKGROUND: The relative efficacy and safety of allopurinol and febuxostat when used according to current guidelines for the treatment of hyperuricemia are unknown. This double-blind noninferiority trial examined these issues. METHODS: Participants with gout and hyperuricemia (with at least 33% having stage 3 chronic kidney disease) were randomly assigned to allopurinol or febuxostat in this 72-week trial, with doses titrated to target serum urate. The trial had three phases: titration (weeks 0 to 24), maintenance (weeks 25 to 48), and observation (weeks 49 to 72). Allopurinol and febuxostat were initiated at daily doses of 100 and 40 mg, with maximum titration to 800 and 120 mg, respectively. Antiinflammatory prophylaxis was given during phases 1 and 2. The primary end point was the proportion of patients experiencing one or more flares during phase 3, with a prespecified noninferiority margin of less than 8 percentage points between allopurinol and febuxostat. Secondary end points included efficacy in patients with chronic kidney disease, proportion achieving target serum urate levels, and serious adverse events. RESULTS: This study included 940 participants; 20.1% withdrew, with similar proportions in treatment arms. During phase 3, 36.5% of allopurinol-treated participants had one flare or more compared with 43.5% of febuxostat-treated participants (P<0.001 for noninferiority). Overall, 80% of participants achieved mean target urates during phase 2 with no differences by treatment. There were no treatment differences (including cardiovascular events) in serious adverse events. CONCLUSIONS: Allopurinol and febuxostat achieved serum urate goals in patients with gout; allopurinol was noninferior to febuxostat in controlling flares. Similar outcomes were noted in participants with stage 3 chronic kidney disease.

An NHC-Mediated Metal-Free Approach towards an NHC-Coordinated Endocyclic Disilene.

A convenient metal-free approach towards an N-heterocyclic carbene (NHC)-coordinated disilene 2 is described. Compound 2, featuring the disilene incorporated in cyclopolysilane framework, was obtained in good yield and characterized using NMR spectroscopy and X-ray crystallography. Density functional theory (DFT) calculations of the reaction mechanism provide a rationale for the observed reactivity and give detailed information on the bonding situation of the base-stabilized disilene. Compound 2 undergoes thermal or light- induced (λ=456 nm) NHC loss, and a dimerization process to give a corresponding dimer with a Si10 skeleton. In order to shed light on the dimerization mechanism, DFT calculations were performed. Moreover, the reactivity of 2 was examined with selected examples of transition metal carbonyl compounds.

Mentoring Underrepresented Minority Physician-Scientists to Success.

As the nation seeks to recruit and retain physician-scientists, gaps remain in understanding and addressing mitigatable challenges to the success of faculty from underrepresented minority (URM) backgrounds. The Doris Duke Charitable Foundation Fund to Retain Clinical Scientists program, implemented in 2015 at 10 academic medical centers in the United States, seeks to retain physician-scientists at risk of leaving science because of periods of extraordinary family caregiving needs, hardships that URM faculty-especially those who identify as female-are more likely to experience. At the annual Fund to Retain Clinical Scientists program directors conference in 2018, program directors-21% of whom identify as URM individuals and 13% as male-addressed issues that affect URM physician-scientists in particular. Key issues that threaten the retention of URM physician-scientists were identified through focused literature reviews; institutional environmental scans; and structured small- and large-group discussions with program directors, staff, and participants. These issues include bias and discrimination, personal wealth differential, the minority tax (i.e., service burdens placed on URM faculty who represent URM perspectives on committees and at conferences), lack of mentorship training, intersectionality and isolation, concerns about confirming stereotypes, and institutional-level factors. The authors present recommendations for how to create an environment in which URM physician-scientists can expect equitable opportunities to thrive, as institutions demonstrate proactive allyship and remove structural barriers to success. Recommendations include providing universal training to reduce interpersonal bias and discrimination, addressing the consequences of the personal wealth gap through financial counseling and benefits, measuring the service faculty members provide to the institution as advocates for URM faculty issues and compensating them appropriately, supporting URM faculty who wish to engage in national leadership programs, and sustaining institutional policies that address structural and interpersonal barriers to inclusive excellence.

Consensus Statement Regarding the Efficacy and Safety of Long-Term Low-Dose Colchicine in Gout and Cardiovascular Disease.

Over the last decade, evidence has demonstrated that long-term, low-dose colchicine (0.5 mg daily) is effective for preventing gout flare and cardiovascular (CV) events in a wide range of patients. Given the potentially expanding use of colchicine in CV disease, we here review and update the biologic effects and safety of colchicine based on recent data gathered from bench and pharmacodynamic studies, clinical reports, controlled clinical trials, and meta-analyses, integrated with important studies over the last 50 years, to offer a consensus perspective by experts from multiple specialties familiar with colchicine's long-term use. We conclude that the clinical benefits of colchicine in gout and CV disease achieved at low dose do not sustain serum levels above the upper limit of safety when used in patients without advanced renal or liver disease or when used concomitantly with most medications. Further, data accrued over the last 50 years strongly suggest that the biologic effects of long-term colchicine do not increase the risk of cancer, sepsis, cytopenia, or myotoxicity.

Chasing the storm: Recruiting non-hospitalized patients for a multi-site randomized controlled trial in the United States during the COVID-19 pandemic.

Randomized controlled trials (RCTs) remain the gold standard to evaluate clinical interventions, producing the highest level of evidence while minimizing potential bias. Inadequate recruitment is a commonly encountered problem that undermines the completion and generalizability of RCTs-and is even more challenging when enrolling amidst a pandemic. Here, we reflect on our experiences with virtual recruitment of non-hospitalized patients in the United States for ColCorona, an international, multicenter, randomized, placebo-controlled coronavirus disease 2019 (COVID-19) drug trial. Recruitment challenges during a pandemic include constraints created by shelter-in-place policies and targeting enrollment according to national and local fluctuations in infection rate. Presenting a study to potential participants who are sick with COVID-19 and may be frightened, overwhelmed, or mistrusting of clinical research remains a challenge. Strategies previously reported to improve recruitment include transparency, patient and site education, financial incentives, and person-to-person outreach. Active measures taken during ColCorona to optimize United States recruitment involved rapid expansion of sites, adjustment of recruitment scripts, assessing telephone calls versus text messages for initial contact with participants, institutional review board-approved financial compensation, creating an infrastructure to systematically identify potentially eligible patients, partnering with testing sites, appealing to both self-interest and altruism, and large-scale media efforts with varying degrees of success.

Chondrocalcinosis: Advances in Diagnostic Imaging.

PURPOSE OF REVIEW: Calcium pyrophosphate deposition disease (CPPD) arises from calcium pyrophosphate deposition throughout the body, leading to different clinical syndromes that may be diagnosed using various imaging modalities. The purpose of this review is to highlight recent updates in the imaging of CPPD. RECENT FINDINGS: Conventional radiography remains the initial test when imaging CPPD; but musculoskeletal ultrasound and conventional computed tomography (CT) may also assist in diagnosing and characterizing CPP deposits, with increased sensitivity. Dual-energy CT is also being used to differentiate CPP crystals from other crystal deposition diseases. CPP discitis has been diagnosed with MRI, but MRI has lower sensitivity and specificity than the aforementioned imaging studies in CPPD diagnosis. Assorted imaging modalities are increasingly used to diagnose CPPD involving atypical joints, avoiding invasive procedures. Each modality has its advantages and disadvantages. Future imaging may be able to provide more utility than what is currently available.

Coincident Kikuchi-Fujimoto's disease and adult-onset Still's disease: report of a patient from an uncommonly affected population and case-directed systematic review.

Kikuchi-Fujimoto's disease (KFD) and adult-onset Still's disease (AOSD) are rare idiopathic inflammatory conditions of unknown etiology. Ten prior instances of KFD and AOSD occurring together have been reported in the medical literature. These overlaps, together with certain distinguishing clinical and laboratory characteristics in these co-occurrences, offer insight into the pathophysiology of both of these rare disorders. Too, examination of these cases may help improve the diagnostic evaluation and care of patients afflicted with these rare diseases. We therefore report an additional patient with KFD and AOSD occurring in a middle-aged Hispanic female patient and perform a systematic literature review using the PubMed/MEDLINE and Embase databases to further analyze and compare prior identified cases. Our observations in our index case complement and expand previous reports, including new demographic and diagnostic features not seen in prior cases of overlap. Indeed ours is the first in a patient of Hispanic ethnicity, with retroperitoneal lymphadenopathy, as well as with a skin biopsy consistent with AOSD. Each of the reviewed cases of co-occurrence met the diagnostic criteria for both KFD and AOSD. This finding, in the setting of unique clinical and diagnostic manifestations that are not typically seen in either disease entity alone, suggests the presence of an overlap syndrome. Also, many of the shared clinical features and symptomatic responses to targeted therapies implies a similar, yet still poorly understood, pathophysiologic pathway for the two diseases.

Colchicine for community-treated patients with COVID-19 (COLCORONA): a phase 3, randomised, double-blinded, adaptive, placebo-controlled, multicentre trial.

BACKGROUND: Evidence suggests a role for excessive inflammation in COVID-19 complications. Colchicine is an oral anti-inflammatory medication beneficial in gout, pericarditis, and coronary disease. We aimed to investigate the effect of colchicine on the composite of COVID-19-related death or hospital admission. METHODS: The present study is a phase 3, randomised, double-blind, adaptive, placebo-controlled, multicentre trial. The study was done in Brazil, Canada, Greece, South Africa, Spain, and the USA, and was led by the Montreal Heart Institute. Patients with COVID-19 diagnosed by PCR testing or clinical criteria who were not being treated in hospital were eligible if they were at least 40 years old and had at least one high-risk characteristic. The randomisation list was computer-generated by an unmasked biostatistician, and masked randomisation was centralised and done electronically through an automated interactive web-response system. The allocation sequence was unstratified and used a 1:1 ratio with a blocking schema and block sizes of six. Patients were randomly assigned to receive orally administered colchicine (0·5 mg twice per day for 3 days and then once per day for 27 days thereafter) or matching placebo. The primary efficacy endpoint was the composite of death or hospital admission for COVID-19. Vital status at the end of the study was available for 97·9% of patients. The analyses were done according to the intention-to-treat principle. The COLCORONA trial is registered with ClinicalTrials.gov (NCT04322682) and is now closed to new participants. FINDINGS: Trial enrolment began in March 23, 2020, and was completed in Dec 22, 2020. A total of 4488 patients (53·9% women; median age 54·0 years, IQR 47·0-61·0) were enrolled and 2235 patients were randomly assigned to colchicine and 2253 to placebo. The primary endpoint occurred in 104 (4·7%) of 2235 patients in the colchicine group and 131 (5·8%) of 2253 patients in the placebo group (odds ratio [OR] 0·79, 95·1% CI 0·61-1·03; p=0·081). Among the 4159 patients with PCR-confirmed COVID-19, the primary endpoint occurred in 96 (4·6%) of 2075 patients in the colchicine group and 126 (6·0%) of 2084 patients in the placebo group (OR 0·75, 0·57-0·99; p=0·042). Serious adverse events were reported in 108 (4·9%) of 2195 patients in the colchicine group and 139 (6·3%) of 2217 patients in the placebo group (p=0·051); pneumonia occurred in 63 (2·9%) of 2195 patients in the colchicine group and 92 (4·1%) of 2217 patients in the placebo group (p=0·021). Diarrhoea was reported in 300 (13·7%) of 2195 patients in the colchicine group and 161 (7·3%) of 2217 patients in the placebo group (p<0·0001). INTERPRETATION: In community-treated patients including those without a mandatory diagnostic test, the effect of colchicine on COVID-19-related clinical events was not statistically significant. Among patients with PCR-confirmed COVID-19, colchicine led to a lower rate of the composite of death or hospital admission than placebo. Given the absence of orally administered therapies to prevent COVID-19 complications in community-treated patients and the benefit of colchicine in patients with PCR-proven COVID-19, this safe and inexpensive anti-inflammatory agent could be considered for use in those at risk of complications. Notwithstanding these considerations, replication in other studies of PCR-positive community-treated patients is recommended.

Designing a Strategy Trial for the Management of Gout: The Use of a Modified Delphi Panel.

OBJECTIVE: Disagreement exists between rheumatology and primary care societies regarding gout management. This paper describes a formal process for gathering input from stakeholders in the planning of a trial to compare gout management strategies. METHODS: We recruited patients, nurses, physician assistants, primary care clinicians, and rheumatologists to participate in a modified Delphi panel (mDP) to provide input on design of a trial focused on optimal management for primary care patients with gout. The 16 panelists received a plain-language briefing document that discussed the rationale for the trial, key clinical issues in gout, and aspects of trial design. The panelists also received information and considerations on nine voting questions (VQs), judged to be the key design questions. Cognitive interviews with panelists ensured that the VQs were understood by the range of panelists involved in the mDP. Panelists were asked to score all VQs from 1 (definitely no) to 9 (definitely yes). Two voting rounds were conducted-round 1 by email and round 2 by video conference. RESULTS: The VQs were modified through the cognitive interviews. The round 1 voting resulted in consensus on eight items, with consensus defined as median voting score in the same tercile (1-3, 4-6 or 7-9). Re-voting at the meeting (round 2) reached consensus on the remaining item. CONCLUSION: An mDP with various stakeholders facilitated consensus on the design of a trial of different management strategies for chronic gout. This method may be useful for designing trials of clinical questions with substantial disagreement across stakeholders.
