The ALPHA Project: Establishing consensus and prioritisation of global community recommendations to address major challenges in lupus diagnosis, care, treatment and research.

The Addressing Lupus Pillars for Health Advancement (ALPHA) Project is a global consensus effort to identify, prioritise and address top barriers in lupus impacting diagnosis, care, treatment and research. To conduct this process, the ALPHA Project convened a multistakeholder Global Advisory Committee (GAC) of lupus experts and collected input from global audiences, including patients. In phase I, the ALPHA Project used expert interviews and a global survey of lupus experts to identify and categorise barriers into three overarching pillars: drug development, clinical care and access to care. In phase II, reported here, the GAC developed recommended actionable solutions to address these previously identified barriers through an in-person stakeholder meeting, followed by a two-round scoring process. Recommendations were assessed for feasibility, impact and timeline for implementation (FIT), where potential FIT component values were between 1 and 3 and total scores were between 3 and 9. Higher scores represented higher achievability based on the composite of the three criteria. Simplifying and standardising outcomes measures, including steroid sparing as an outcome (drug development) and defining the lupus spectrum (clinical care) ranked as the highest two priority solutions during the GAC meeting and received high FIT scores (7.67 and 7.44, respectively). Leveraging social media (access to care) received the highest FIT score across all pillars (7.86). Cross-cutting themes of many solutions include leveraging digital technology and applying specific considerations for special populations, including paediatrics. Implementing the recommendations to address key barriers to drug development, clinical care and access to care is essential to improving the quality of life of adults and children with lupus. Multistakeholder collaboration and guidance across existing efforts globally is warranted.

Global consensus building and prioritisation of fundamental lupus challenges: the ALPHA project.

OBJECTIVE: Lupus is a complex, heterogeneous autoimmune disease that has yet to see significant progress towards more timely diagnosis, improved treatment options for short-term and long-term outcomes, and appropriate access to care. The Addressing Lupus Pillars for Health Advancement (ALPHA) project is the first step in establishing global consensus and developing concrete strategies to address the challenges limiting progress. METHODS: A Global Advisory Committee of 13 individuals guided the project and began barrier identification. Seventeen expert interviews were conducted to further characterise key barriers. Transcripts were analysed using Nvivo and a codebook was created containing a list of thematic 'nodes' (topics) and their descriptions. Findings were used to develop a final survey instrument that was fielded to a diverse, international stakeholder audience to achieve broad consensus. RESULTS: Expert interviews identified lupus heterogeneity as the primary barrier hindering advancement. Subsequent barriers were categorised into three areas: (1) Drug development. (2) Clinical care. (3) Access and value. The global survey received 127 completed responses from experts across 20 countries. Respondents identified barriers as high priority including the lack of biomarkers for clinical and drug development use, flawed clinical trial design, lack of access to clinicians familiar with lupus, and obstacles to effective management of lupus due to social determinants of care. Respondents also identified 30 autoimmune conditions that may be lupus-related based on overlapping features, shared autoantibodies and pathophysiology. CONCLUSIONS: ALPHA is a comprehensive initiative to identify and prioritise the continuum of challenges facing people with lupus by engaging a global audience of lupus experts. It also explored views on lupus as a spectrum of related diseases. Conclusions from this effort provide a framework to generate actionable approaches to the identified high-priority barriers.

Core Curriculum to Facilitate the Expansion of a Rheumatology Practice to Include Nurse Practitioners and Physician Assistants.

OBJECTIVE: Due to an aging population, increasing prevalence of rheumatic disease, and a growing supply and demand gap of rheumatology providers, innovative solutions are needed to meet the needs of persons with rheumatic conditions. Nurse practitioners (NPs) and physician assistants (PAs) have been identified as a group of health professionals who could help address the workforce shortage. The Executive Committee of the Association of Rheumatology Health Professionals (ARHP), a division of the American College of Rheumatology (ACR), charged a task force to facilitate the preparation of NPs/PAs to work in a rheumatology practice setting. METHODS: The task force, consisting of private practice and academic rheumatologists, and NPs and PAs, from both adult and pediatric settings, conducted a needs assessment survey of current NPs and PAs to identify mechanisms for acquiring rheumatology knowledge. Through face-to-face and webinar meetings, and incorporating stakeholder feedback, the task force designed a rheumatology curriculum outline to enrich the training of new NPs and PAs joining rheumatology practice. RESULTS: Informed by the needs assessment data and stakeholders, an NP/PA rheumatology curriculum outline was developed and endorsed by the ACR Board of Directors for use by community-based and academic rheumatology practices, whether pediatric or adult, who desire to add NPs and PAs to their practice setting. CONCLUSION: As rheumatology is facing workforce shortages, the ACR/ARHP rheumatology curriculum outline can be utilized to train NPs and PAs and create more efficient integration of NPs and PAs into rheumatology practice.

Gut Microbiota Perturbations in Reactive Arthritis and Postinfectious Spondyloarthritis.

OBJECTIVE: Reactive arthritis (ReA) is an inflammatory disorder occurring several weeks after gastrointestinal or genitourinary tract infections. HLA-B27 positivity is considered a risk factor, although it is not necessarily predictive of disease incidence. Among nongenetic factors, the intestinal microbiome may play a role in disease susceptibility. The objective of this study was to characterize the gut microbiota and host gene interactions in ReA and postinfectious spondyloarthritis. METHODS: Adult subjects with peripheral spondyloarthritis and control subjects with preceding infections who did not develop arthritis were prospectively recruited from a geographic region with a high prevalence of ReA. Clinical variables, HLA status, and 16S ribosomal RNA gene sequencing of intestinal microbiota were analyzed. RESULTS: Subjects with ReA showed no significant differences from controls in gut bacterial richness or diversity. However, there was a significantly higher abundance of Erwinia and Pseudomonas and an increased prevalence of typical enteropathogens associated with ReA. Subjects with ultrasound evidence of enthesitis were enriched in Campylobacter, while subjects with uveitis and radiographic sacroiliitis were enriched in Erwinia and unclassified Ruminococcaceae, respectively; both were enriched in Dialister. Host genetics, particularly HLA-A24, were associated with differences in gut microbiota diversity irrespective of disease status. We identified several co-occurring taxa that were also predictive of HLA-A24 status. CONCLUSION: This is the first culture-independent study characterizing the gut microbial community in postinfectious arthritis. Although bacterial factors correlated with disease presence and clinical features of ReA, host genetics also appeared to be a major independent driver of intestinal community composition. Understanding of these gut microbiota-host genetic relationships may further clarify the pathogenesis of postinfectious spondyloarthritides.

Teaching about how doctors think: a longitudinal curriculum in cognitive bias and diagnostic error for residents.

BACKGROUND: Trends in medical education have reflected the patient safety movement's initial focus on systems. While the role of cognitive-based diagnostic errors has been increasingly recognised among safety experts, literature describing strategies to teach about this important problem is scarce. METHODS: 48 PGY-2 internal medicine residents participated in a three-part, 1-year curriculum in cognitive bias and diagnostic error. Residents completed a multiple-choice test designed to assess the recognition and knowledge of common heuristics and biases both before and after the curriculum. Results were compared with PGY-3 residents who did not receive the curriculum. An additional assessment in which residents reviewed video vignettes of clinical scenarios with cognitive bias and debiasing techniques was embedded into the curriculum. RESULTS: 38 residents completed all three parts of the curriculum and completed all assessments. Performance on the 13-item multiple-choice knowledge test improved post-curriculum when compared to both pre-curriculum performance (9.26 vs 8.26, p=0.002) and the PGY-3 comparator group (9.26 vs 7.69, p<0.001). All residents correctly identified at least one cognitive bias and proposed at least one debiasing strategy in response to the videos. CONCLUSIONS: A longitudinal curriculum in diagnostic error and cognitive bias improved internal medicine residents' knowledge and recognition of cognitive biases as measured by a novel assessment tool. Further study is needed to refine learner assessment tools and examine optimal strategies to teach clinical reasoning and cognitive bias avoidance strategies.

Readability and suitability assessment of patient education materials in rheumatic diseases.

OBJECTIVE: Web-based patient education materials and printed pamphlets are frequently used by providers to inform patients about their rheumatic disease. Little attention has been given to the readability and appropriateness of patient materials. The objective of this study was to examine the readability and suitability of commonly used patient education materials for osteoarthritis (OA), rheumatoid arthritis, systemic lupus erythematosus, and vasculitis. METHODS: Five or 6 popular patient resources for each disease were chosen for evaluation. Readability was measured using the Flesch-Kincaid reading grade level and suitability was determined by the Suitability Assessment of Materials (SAM), a score that considers characteristics such as content, graphics, layout/topography, and cultural appropriateness. Three different reviewers rated the SAM score and means were used in the analysis. RESULTS: Twenty-three resources written on the 4 diseases were evaluated. The education material for all 4 diseases studied had readability above the eighth-grade level and readability did not differ among the diseases. Only 5 of the 23 resources received superior suitability scores, and 3 of these 5 resources were written for OA. All 4 diseases received adequate suitability scores, with OA having the highest mean suitability score. CONCLUSION: Most patient education materials for rheumatic diseases are written at readability levels above the recommended sixth-grade reading level and have only adequate suitability. Developing more appropriate educational resources for patients with rheumatic diseases may improve patient comprehension.

Seen through their eyes: residents' reflections on the cognitive and contextual components of diagnostic errors in medicine.

PURPOSE: Diagnostic errors in medicine are common and costly. Cognitive bias causes are increasingly recognized contributors to diagnostic error but remain difficult targets for medical educators and patient safety experts. The authors explored the cognitive and contextual components of diagnostic errors described by internal medicine resident physicians through the use of an educational intervention. METHOD: Forty-one internal medicine residents at University of Pennsylvania participated in an educational intervention in 2010 that comprised reflective writing and facilitated small-group discussion about experiences with diagnostic error from cognitive bias. Narratives and discussion were transcribed and analyzed iteratively to identify types of cognitive bias and contextual factors present. RESULTS: All residents described a personal experience with a case of diagnostic error that contained at least one cognitive bias and one contextual factor that may have influenced the outcome. The most common cognitive biases identified by the residents were anchoring bias (36; 88%), availability bias (31; 76%), and framing effect (23; 56%). Prominent contextual factors included caring for patients on a subspecialty service (31; 76%), complex illness (26; 63%), and time pressures (22; 54%). Eighty-five percent of residents described at least one strategy to avoid a similar error in the future. CONCLUSIONS: Residents can easily recall diagnostic errors, analyze the errors for cognitive bias, and richly describe their context. The use of reflective writing and narrative discussion is an educational strategy to teach recognition, analysis, and cognitive-bias-avoidance strategies for diagnostic error in residency education.

Synovial xanthomatosis: are there clues to mechanisms for this rare disease?

We report a 64-year-old man with arthritis and nodules to describe that this picture can be caused by normo-lipidemic xanthomas. Light and electron microscopy (EM) plus polymerase chain reaction (PCR) studies were performed for diagnosis and investigation. These showed features typical of xanthomas plus PCR and EM evidence of possible infection with Chlamydia pneumoniae as a pathogenetic mechanism deserving consideration. With such rare diseases, any clues to possible mechanisms seem important to record and thus to encourage future investigations. This uncommon cause of arthritis and nodules had been confused with rheumatoid arthritis by others in this case.

Associations between body mass, radiographic joint damage, adipokines and risk factors for bone loss in rheumatoid arthritis.

OBJECTIVE: To evaluate the association between BMI and radiographic joint damage (RJD) in RA. METHODS: van der Heijde-Sharp (vdHS) erosion scores were determined in 499 participants with RA, ages 18-85 years, while enrolled in a clinical trial of golimumab (GO-BEFORE trial). Subjects were MTX and biologic therapy naïve. Multivariable logistic regressions determined the odds of prevalent RJD (defined as vdHS score >10) according to BMI category. Longitudinal analyses evaluated the association between BMI category and progression of vdHS score over 52 weeks. Analyses in a subset of 100 participants examined the association between adipokines and vdHS scores. RESULTS: At enrolment and 52 weeks, 37.6 and 43.6% of participants had RJD. Compared with normal weight, obese subjects had lower odds of RJD [0.40 (95% CI 0.22, 0.74); P = 0.003], and underweight subjects had greater odds [3.86 (95% CI 1.66, 9.00); P = 0.002] at baseline, adjusted for demographic and disease characteristics. The baseline associations between BMI category and RJD were greater among participants with multiple risk factors for bone loss (female >50 years, smoking, glucocorticoid exposure and vitamin D deficiency); test for interaction P = 0.05. Adjustment for adiponectin levels did not attenuate the association between BMI and vdHS scores. Baseline BMI and change in weight did not independently predict radiographic progression (P > 0.1). CONCLUSIONS: Higher BMI was independently associated with less RJD and was greatest in participants with risk factors for bone loss. Future studies are needed to examine the associations between RJD, obesity, weight loss and osteoporosis.

Development and evaluation of a survey of gout patients concerning their knowledge about gout.

OBJECTIVE: The objective of the study was to develop and test a survey of gout patients regarding their level of disease-related knowledge, to identify potential targets for patient education. METHODS: A 10-item questionnaire with readability at a Flesch-Kincaid grade level of 4.6 and Flesch reading ease of 83.9% was designed to address parameters considered important for patient participation in the management of gout. The questionnaire was primarily evaluated at the Veterans Affairs (VA) Medical Center in Philadelphia, but was also secondarily performed at 2 Chinese hospitals, the Sun Yat-sen Memorial Hospital of Zhong Shan University, Guangdong Province (GZ), and the Qingdao Municipal Hospital, Qingdao City, Shandong Province (QD). Demographic and questionnaire data by institution were evaluated using descriptive statistics, and significant differences were identified by χ and Fisher exact tests. Patient responses were displayed by each individual question and by the distribution of total scores. Kruskal-Wallis tests of significance were used for nonparametric or skewed data. Intraclass correlations (ICCs) were performed within the VA population to determine internal consistency of the individual questions. A high score was defined as greater than 7 (the median value). Multivariate regression models using demographic and clinical characteristics attempted to identify factors associated with correct answers to each question. RESULTS: Total correct score for individual patients varied widely at each institution with a mean (SD) and median (interquartile range [IQR]) scores in all 3 hospitals of 6.15 (2.25) and 7 (5-8), respectively. The average numbers of correct responses for each institution were 4.38 (SD, 3.04) (median, 4 [IQR, 2-7]) at GZ; 7.05 (SD, 1.37) (median, 8 [IQR, 6-8]) at QD; 6.21 (SD, 1.74) (median, 7 [IQR, 6-7]) at VA; P = 0.0010. Two questions (Q4 and Q10) were identified as difficult to understand by patients and showed poor ICC (ICC = 0.0000, P > 0.5) at the VA. Questions that were more difficult to answer were (1) Q3: What inside the joint causes attacks of gout? (GZ, 28.6%; QD, 7.7%; VA, 72.4%; P = 0.000); (2) Q8: How long should patients continue with serum uric acid-lowering drugs? (GZ, 19.1%; QD, 10.3%; VA, 82.7%; P = 0.000); (3) Q6: The ideal serum uric acid to aim at during treatment? (GZ, 42.8%; QD, 89.7%; and VA, 17.2%; P = 0.000); and (4) Q5: Which drugs can lower serum uric acid? (GZ, 61.9%; QD, 89.7%; VA, 51.7%; P = 0.002). CONCLUSIONS: This study describes an easy-to-read 10-item questionnaire that can identify important knowledge gaps in patients with gout. This can be the first step in designing educational interventions to improve patient understanding and improve clinical care.

Genetic and lifestyle variables associated with homocysteine concentrations and the distribution of folate derivatives in healthy premenopausal women.

BACKGROUND: Low folate and high homocysteine (Hcy) concentrations are associated with pregnancy-related pathologies such as spina bifida. Polymorphisms in folate/Hcy metabolic enzymes may contribute to this potentially pathogenic biochemical phenotype. METHODS: The study comprised 26 Caucasian and 23 African-American premenopausal women. Subjects gave fasting blood samples for biochemical phenotyping and genotyping. Total Hcy (tHcy) and both plasma and red blood cell (RBC) folate derivatives (i.e. tetrahydrofolate [THF], 5-methylTHF [5-MTHF], and 5,10-methenylTHF [5,10-MTHF]) were measured using stable isotope dilution liquid chromatography, multiple reaction monitoring, and mass spectrometry. Eleven polymorphisms from nine folate/Hcy pathway genes were genotyped. Tests of association between genetic, lifestyle, and biochemical variables were applied. RESULTS: In African American women, tHcy concentrations were associated (p < 0.05) with total RBC folate, RBC 5-MTHF, B(12), and polymorphisms in methionine synthase (MTR) and thymidylate synthase (TYMS). In Caucasian women, tHcy concentrations were not associated with total folate levels, but were associated (p < 0.05) with RBC THF, ratios of RBC 5-MTHF:THF, and polymorphisms in 5,10-methylenetetrahydrofolate reductase (MTHFR) and MTR. In African Americans, folate derivative levels were associated with smoking, B(12), and polymorphisms in MTR, TYMS, methionine synthase reductase (MTRR), and reduced folate carrier1 (RFC1). In Caucasians, folate derivative levels were associated with vitamin use, B(12), and polymorphisms in MTHFR, TYMS, and RFC1. CONCLUSIONS: Polymorphisms in the folate/Hcy pathway are associated with tHcy and folate derivative levels. In African American and Caucasian women, different factors are associated with folate/Hcy phenotypes and may contribute to race-specific differences in the risks of a range of pregnancy-related pathologies.

A roadmap for education to improve the quality of care in gout.

PURPOSE OF REVIEW: To describe obstacles to optimum management of gout by primary care physicians and to propose educational interventions to improve care. RECENT FINDINGS: In the past, gout education has been hampered by infrequency of continuing medical education courses, loss of excitement for a disease in which therapies have not changed (until recently), insufficient evidence-based medicine, and the lack of motivation by physicians to re-learn this disease once in active practice. We identify 10 common myths that impede appropriate treatment of gout, identify gaps in evidence-based medicine that perpetuate those myths, and propose opportunities to improve education on these myths. It is through better gout-centered education that quality of care in gout can be enhanced. Residency may be one of the key points of intervention. As more evidence-based medicine publications address the optimum management of gout, national re-education can occur. More outreach by community rheumatologists to primary care physicians through educational programs and improved referral letters can help re-educate practitioners. Lastly, an often overlooked engine to change physician practices is consumer education, but current patient education programs are lacking. SUMMARY: Novel education interventions for physician trainees, primary care physicians, and patients are proposed to improve the care of patients with gout.

The brief CV review session: one component of a mosaic of mentorship for women in academic medicine.

BACKGROUND: In the current climate of increasing demands on a disproportionately small number of senior female faculty, we implemented a brief curriculum vitae (CV) review session as an opportunity to expand the professional network of junior women faculty and provide them with additional formal career advice. METHODS: For 3 years, junior (mentees) and senior (mentors) faculty from different departments were paired in half-hour CV review sessions, as part of an annual conference focused on professional development for faculty women. Participating faculty received questionnaires to assess their experience with the sessions, and their feedback was combined over all 3 years and compared using chi2 and Fisher's tests. RESULTS: During the 3 years, there were 93 CV review sessions. Although 84% of the mentees reported having a mentor, only 62% of mentees reported that any previous mentoring experience was helpful. Most (90%) participated in the CV review to determine if their career was "on track." The mentees reported that the CV review session was helpful (93%), provided new information (87%), and identified that they were "on track" for promotion (75%). The mentors felt that their mentees were progressing appropriately in their career (78%) and provided specific recommendations for the mentees (100%). The majority (78%) of mentors felt comfortable mentoring junior faculty outside their department. CONCLUSIONS: Brief interventions, such as a CV review session, can provide additional counsel to junior faculty, helping them assess their career progress as part of a mosaic of mentorship.

Folate and homocysteine phenotypes: Comparative findings using research and clinical laboratory data.

OBJECTIVES: A low folate/high homocysteine phenotype is associated with several pathologies, including spina bifida and cardiovascular disease. Folate and total homocysteine (tHcy) measurements are used clinically to assess risk and the need for folic acid supplementation and in research to investigate the metabolic basis of disease. Red blood cell (RBC) folate, the best indicator of long-term folate status, is usually measured as "total" folate. However, different folate derivatives support distinct biochemical functions, suggesting a need to develop more precise methods. This study was designed to evaluate a method based on stable isotope dilution liquid chromatography-multiple reaction monitoring/mass spectrometry (LC-MRM/MS). DESIGN AND METHODS: We used LC-MRM/MS to quantify the RBC folate derivatives 5-methyltetrahydrofolate (5-CH(3)-THF), tetrahydrofolate (THF), and 5,10-methenyltetrahydrofolate (5,10-methenylTHF) in pre-menopausal women. The concentration of each folate derivative was assessed for utility in predicting tHcy levels, and compared to folate and tHcy measurements derived by routine clinical laboratory methods. RESULTS: LC-MRM/MS was qualitatively and quantitatively superior to routine clinical laboratory methods for determining folate and tHcy concentrations. RBC 5-CH(3)-THF had a reciprocal relationship with tHcy (p=0.0003), whereas RBC THF and RBC 5,10-methenylTHF had direct relationships (p=0.01, 0.04 respectively). In combination, these three variables accounted for 42% of the variation in tHcy. CONCLUSIONS: Robust methods for measuring RBC 5-CH(3)-THF would improve the utility of folate/homocysteine phenotyping in patient management. The use of LC-MRM/MS would allow studies of hyperhomocysteinemia and diseases associated with a low folate/high homocysteine phenotype to be performed with less measurement error and greater statistical power to generate data with the potential to elucidate the etiologic mechanisms of complex diseases and traits.
