Real-world effectiveness and persistence of secukinumab in the treatment of patients with psoriatic arthritis.

Introduction: Psoriatic arthritis (PsA) is a complex and heterogeneous inflammatory disease. Secukinumab, a biologic disease-modifying antirheumatic drug (bDMARD), has extensive clinical evidence of efficacy and safety in the treatment of PsA but data in clinical practice are still limited. This study aims to provide real-world evidence on secukinumab use, effectiveness, and persistence in PsA. Methods: A retrospective, multicenter study was conducted on patients diagnosed with PsA and treated with secukinumab up to June 2021 at 12 centers in the Valencian Community (Spain). Data on DAS28-CRP, DAPSA, Tender and Swollen Joint Counts (TJC, SJC), enthesitis, dactylitis, skin and nail involvement, pain, patient and physician global assessment (ptGA, phGA) using 100-mm visual analog scale (VAS), and persistence for up to 24 months were collected. Results: A total of 178 patients were included (49% men; mean [standard deviation, SD] age: 51.4 [10.5] years; 39% obese). Secukinumab was used as a first-, second-, or ≥ third-line bDMARD in 37, 21, and 42% of patients, respectively. The percentage of patients achieving at least low disease activity (DAS28-CRP ≤ 3.2) increased from 25% at baseline to 66% at month 6 (M6) and was maintained (75%) up to M24. Mean (SD) DAS28-CRP baseline values (3.9 [1.2]) decreased to 2.9 (1.1) (p < 0.001) at M6 and remained low through M24 (2.6 [1.1]) (p < 0.001). Secukinumab also improved peripheral arthritis increasing the percentage of patients with TJC = 0 (20% baseline; 57% M24) and SJC = 0 (37% baseline; 80% M24). Treatment reduced the percentage of patients with enthesitis (25% baseline; 6% M24), dactylitis (20% baseline; 4% M24), and skin (70% baseline; 17% M24), and nail (32% baseline; 2% M24) involvement. Additionally, we observed improvements in the mean pain VAS (-26.4 mm M24), ptGA (-26.2 mm M24), and phGA (-24.8 mm M24). Secukinumab showed an overall 24-month persistence rate of 67% (95% confidence interval [CI]: 60-74%). Patients receiving first-line secukinumab showed the highest 24-month persistence rate (83, 95% CI: 73-92; p = 0.024). Conclusion: Secukinumab showed long-term effectiveness across the six key PsA domains thus reducing disease activity and pain, which are major treatment goals. This was accompanied by high persistence rates, especially in bDMARD naive patients.

The 2023 ACR/EULAR Classification Criteria for Calcium Pyrophosphate Deposition Disease.

OBJECTIVE: Calcium pyrophosphate deposition (CPPD) disease is prevalent and has diverse presentations, but there are no validated classification criteria for this symptomatic arthritis. The American College of Rheumatology (ACR) and EULAR have developed the first-ever validated classification criteria for symptomatic CPPD disease. METHODS: Supported by the ACR and EULAR, a multinational group of investigators followed established methodology to develop these disease classification criteria. The group generated lists of candidate items and refined their definitions, collected de-identified patient profiles, evaluated strengths of associations between candidate items and CPPD disease, developed a classification criteria framework, and used multi-criterion decision analysis to define criteria weights and a classification threshold score. The criteria were validated in an independent cohort. RESULTS: Among patients with joint pain, swelling, or tenderness (entry criterion) whose symptoms are not fully explained by an alternative disease (exclusion criterion), the presence of crowned dens syndrome or calcium pyrophosphate crystals in synovial fluid are sufficient to classify a patient as having CPPD disease. In the absence of these findings, a score >56 points using weighted criteria, comprising clinical features, associated metabolic disorders, and results of laboratory and imaging investigations, can be used to classify as CPPD disease. These criteria had a sensitivity of 92.2% and specificity of 87.9% in the derivation cohort (190 CPPD cases, 148 mimickers), whereas sensitivity was 99.2% and specificity was 92.5% in the validation cohort (251 CPPD cases, 162 mimickers). CONCLUSION: The 2023 ACR/EULAR CPPD disease classification criteria have excellent performance characteristics and will facilitate research in this field.

Points to consider: EULAR-UEMS standards for the training of European rheumatologists.

BACKGROUND: Postgraduate rheumatology training programmes are already established at a national level in most European countries. However, previous work has highlighted a substantial level of heterogeneity in the organisation and, in part, content of programmes. OBJECTIVE: To define competences and standards of knowledge, skills and professional behaviours required for the training of rheumatologists. METHODS: A European Alliance of Associations for Rheumatology (EULAR) task force (TF) of 23 experts, including two members of the European Union of Medical Specialists (UEMS) section of rheumatology, was convened. The mapping phase consisted of the retrieval of key documents on specialty training in rheumatology and other related specialties across a broad set of international sources. The content of these documents was extracted and represented the foundation for the document draft that underwent several rounds of online discussion within the TF, and afterwards was also distributed to a broad group of stakeholders for collecting feedback. The list of generated competences was voted on during the TF meetings, while the level of agreement (LoA) with each statement was established by anonymous online voting. RESULTS: A total of 132 international training curricula were retrieved and extracted. In addition to the TF members, 253 stakeholders commented and voted on the competences through an online anonymous survey. The TF developed (1) an overarching framework indicating the areas that should be addressed during training, (2) 7 domains defining broad areas that rheumatology trainees should master by the end of the training programme, (3) 8 core themes defining the nuances of each domain and (4) 28 competences that trainees should acquire to cover each of the areas outlined in the overarching framework. A high LoA was achieved for all competences. CONCLUSION: These points to consider for EULAR-UEMS standards for the training of European rheumatologists are now defined. Their dissemination and use can hopefully contribute to harmonising training across European countries.

Real-world experience with secukinumab in the entire axial spondyloarthritis spectrum.

Background: Secukinumab is a biologic disease-modifying antirheumatic drug (bDMARD) that has demonstrated efficacy in the treatment of axial spondyloarthritis (axSpA, i.e., ankylosing spondylitis and non-radiographic axSpA) across various clinical trials. However, data of secukinumab in clinical practice is still limited. Here, we aimed to provide real-world data on secukinumab use, effectiveness, and persistence in axSpA. Patients and methods: Retrospective, multicenter study of patients with a diagnosis of axSpA treated with secukinumab at 12 centers up to June 2021 in the Valencian Community (Spain). Information was gathered on BASDAI measurement, pain, patient and physician global assessment (ptGA, phGA) using a 100-mm visual analog scale (VAS), persistence and other secondary variables by treatment line (first, second, and ≥ third) for up to 24 months. Results: 221 patients were included (69% men; mean age [standard deviation, SD]: 46.7 [12.1] years old). Secukinumab was used as a first-line bDMARD in 38% of patients, as a second-line in 34% and as a ≥ hird-line in 28%. The percentage of patients achieving low disease activity (BASDAI<4) increased from 9% at baseline to 48% at month 6 and was maintained (49%) up to month 24. The greatest improvement in BASDAI was observed in naïve patients (month 6: -2.6; month 24: -3.7), followed by second-line (month 6: -1.9; month 24: -3.1) and ≥ third-line (month 6: -1.3; month 24: -2.3) patients. Reductions in mean pain VAS (-23.3; -31.9), ptGA (-25.1; -31.9) and phGA (-25.1; -31) were also observed at 6 and 24 months. Secukinumab showed an overall 12-months persistence rate of 70% (95% confidence interval [CI]: 63-77%) and a 24-months persistence rate of 58% (95% CI, 51-66%). Patients receiving first-line secukinumab had the highest 24-months persistence rate (p = 0.05). Conclusion: Secukinumab improved disease activity in axSpA patients, especially in naive, and second-line patients, which was accompanied by high persistence rates up to 24 months.

Optimisation of tocilizumab therapy in giant cell arteritis. A multicentre real-life study of 471 patients.

OBJECTIVES: Tocilizumab (TCZ) is the only biologic therapy approved for giant cell arteritis (GCA). There is general agreement on the initial/maintenance dose, duration of TCZ therapy is not well established. In GiACTA trial, after one year on TCZ, most patients had GCA relapse after withdrawal. The aim of this study is to assess the effectiveness and safety of TCZ therapy optimisation in a large unselected series of patients with GCA in a clinical practice scenario. METHODS: We carried out a multicentre study on 471 GCA patients treated with TCZ. Once prolonged remission was achieved (n=231) and based on a decision between patient and physician, TCZ was optimised (n=125). We compared optimised (TCZOPT) and not optimised (TCZNON-OPT) groups. Prolonged remission defined as normalisation of clinical and laboratory data for 6 months. Optimisation was carried out by decreasing TCZ dose and/or increasing dosing interval. RESULTS: We evaluated 231 GCA patients on TCZ in prolonged remission. At TCZ onset, no differences in demographic, clinical, or laboratory data were observed. First TCZ optimisation was performed after a median follow-up of 12[6-17] months. Intravenous TCZ was optimised from 8 to 4mg/kg/4weeks in 44% patients, while subcutaneous TCZ was optimised from 162mg/w to 162mg/every-other-week in 65% cases. At the end of follow-up, prolonged remission (78.2% vs. 84.2%; p=0.29) and relapses (5.6% vs. 10.4%, p=0.177) were similar in TCZOPT vs. TCZNON-OPT. Severe infections were more frequent in TCZNON-OPT (12.9% vs. 6.6%; p=0.009). CONCLUSIONS: TCZ optimisation may be done once complete remission is achieved by reducing dose or increasing dosing interval. This seems to be effective, safe and cost-effective therapeutic scheme.

A glance into the future of gout.

Gout is characterized by monosodium urate (MSU) crystal deposits in and within joints. These deposits result from persistent hyperuricaemia and most typically lead to recurrent acute inflammatory episodes (gout flares). Even though some aspects of gout are well characterized, uncertainties remain; this upcoming decade should provide further insights into many of these uncertainties. Synovial fluid analysis allows for the identification of MSU crystals and unequivocal diagnosis. Non-invasive methods for diagnosis are being explored, such as Raman spectroscopy and imaging modalities. Both ultrasound and dual-energy computed tomography (DECT) allow the detection of MSU crystals; this not only provides a mean of diagnosis, but also has furthered gout knowledge defining the presence of a preclinical deposition in asymptomatic hyperuricaemia. Scientific consensus establishes the beginning of gout as the beginning of symptoms (usually the first flare), but the concept is currently under review. For effective long-term gout management, the main goal is to promote crystal dissolution treatment by reducing serum urate below 6 mg/dL (or 5 mg/dL if faster crystal dissolution is required). Current urate-lowering therapies' (ULTs) options are limited, with allopurinol and febuxostat being widely available, and probenecid, benzbromarone, and pegloticase available in some regions. New xanthine oxidase inhibitors and, especially, uricosurics inhibiting urate transporter URAT1 are under development; it is probable that the new decade will see a welcomed increase in the gout therapeutic armamentarium. Cardiovascular and renal comorbidities are common in gout patients. Studies determining whether optimal treatment of gout will positively impact these comorbidities are currently lacking, but will hopefully be forthcoming. Overall, the single change that will most impact gout management is greater uptake of international rheumatology society recommendations. Innovative strategies, such as nurse-led interventions based on these recommendations have recently demonstrated treatment success for people with gout.

Tocilizumab in visual involvement of giant cell arteritis: a multicenter study of 471 patients.

Background: Visual involvement is the most feared complication of giant cell arteritis (GCA). Information on the efficacy of tocilizumab (TCZ) for this complication is scarce and controversial. Objective: We assessed a wide series of GCA treated with TCZ, to evaluate its role in the prevention of new visual complications and its efficacy when this manifestation was already present before the initiation of TCZ. Design: This is an observational multicenter study of patients with GCA treated with TCZ. Methods: Patients were divided into two subgroups according to the presence or absence of visual involvement before TCZ onset. Visual manifestations were classified into the following categories: transient visual loss (TVL), permanent visual loss (PVL), diplopia, and blurred vision. Results: Four hundred seventy-one GCA patients (mean age, 74 ± 9 years) were treated with TCZ. Visual manifestations were observed in 122 cases (26%), of which 81 were present at TCZ onset: PVL (n = 60; unilateral/bilateral: 48/12), TVL (n = 17; unilateral/bilateral: 11/6), diplopia (n = 2), and blurred vision (n = 2). None of the patients without previous visual involvement or with TVL had new episodes after initiation of TCZ, while only 11 out of 60 (18%) patients with PVL experienced some improvement. The two patients with diplopia and one of the two patients with blurred vision improved. Conclusion: TCZ may have a protective effect against the development of visual complications or new episodes of TVL in GCA. However, once PVL was established, only a few patients improved.

Current state, control, impact and management of rheumatoid arthritis according to patient: AR 2020 national survey.

OBJECTIVES: To analyse current status, control and impact of RA on patients' lives as well as the management of RA symptoms. METHODS: A structured anonymous online questionnaire was designed and sent to patients with RA, aged 18 years or above living in Spain. Participants were invited though different strategies: 1) ConArtritis and related patients associations; 2) Patients participating in the platform www.in-pacient.es; 3) Links from ConArtritis website and open social networks. Sociodemographic and clinical variables, as well as others related to the objectives were collected. A descriptive analysis was performed. RESULTS: We analysed 882 RA patients, 89% women, with a median age of 52 years, 31.9% disease duration <5 years. They reported a mean pain and patient global disease score (0-10) of 5.1 and 4.9 respectively. The rate of patients with many difficulties or inability to perform daily tasks varied from 6.4% to 49.2%. Based on the activity index 56.8% of patients reported high activity. We found a great or severe impact on the emotional well-being in 31.5% of patients, and of 29.2% in the workplace or academic setting. A total of 87.9% are taking some medication for RA, and 17.3% are little/not satisfied with them. In addition, 67.1% take conventional synthetic disease modifying drugs (DMARDs), and 45.9% biological therapies including biosimilars and small molecules. CONCLUSIONS: The current impact of RA on patients' daily lives remains very high. A significant number of patients are not taking DMARDs (conventional synthetic and/or biologics) despite high activity.

Biologic therapy in refractory neurobehçet's disease: a multicentre study of 41 patients and literature review.

OBJECTIVES: To assess efficacy and safety of biologic therapy (BT) in neurobehçet's disease (NBD) refractory to glucocorticoids and at least one conventional immunosuppressive drug. METHODS: Open-label, national, multicentre study. NBD diagnosis was based on the International Consensus Recommendation criteria. Outcome variables were efficacy and safety. Main efficacy outcome was clinical remission. Other outcome variables analysed were glucocorticoid-sparing effect and improvement in laboratory parameters. RESULTS: We studied 41 patients [21 women; age 40.6 (10.8) years]. Neurological damage was parenchymal (n = 33, 80.5%) and non-parenchymal (n = 17, 41.5%). First BTs used were infliximab (n = 19), adalimumab (n = 14), golimumab (n = 3), tocilizumab (n = 3) and etanercept (n = 2). After 6 months of BT, neurological remission was complete (n = 23, 56.1%), partial (n = 15, 37.6%) and no response (n = 3, 7.3%). In addition, median (IQR) dose of oral prednisone decreased from 60 (30-60) mg/day at the initial visit to 5 (3.8-10) mg/day after 6 months (P < 0.001). It was also the case for mean erythrocyte sedimentation rate [31.5 (25.6)-15.3 (11.9) mm/1st h, P = 0.011] and median (IQR) C-reactive protein [1.4 (0.2-12.8) to 0.3 (0.1-3) mg/dl, P = 0.001]. After a mean follow-up of 57.5 months, partial or complete neurological remission persisted in 37 patients (90.2%). BT was switched in 22 cases (53.6%) due to inefficacy (n = 16) or adverse events (AEs) (n = 6) and discontinued due to complete prolonged remission (n = 3) or severe AE (n = 1). Serious AEs were observed in two patients under infliximab treatment. CONCLUSIONS: BT appears to be effective and relatively safe in refractory NBD.

Identifying Potential Classification Criteria for Calcium Pyrophosphate Deposition Disease: Item Generation and Item Reduction.

OBJECTIVE: Classification criteria for calcium pyrophosphate deposition (CPPD) disease will facilitate clinical research on this common crystalline arthritis. Our objective was to report on the first 2 phases of a 4-phase process for developing CPPD classification criteria. METHODS: CPPD classification criteria development is overseen by a 12-member steering committee. Item generation (phase I) included a scoping literature review of 5 literature databases and contributions from a 35-member combined expert committee and 2 patient research partners. Item reduction and refinement (phase II) involved a combined expert committee meeting, discussions among clinical, imaging, and laboratory advisory groups, and an item-rating exercise to assess the influence of individual items toward classification. The steering committee reviewed the modal rating score for each item (range -3 [strongly pushes away from CPPD] to +3 [strongly pushes toward CPPD]) to determine items to retain for future phases of criteria development. RESULTS: Item generation yielded 420 items (312 from the literature, 108 from experts/patients). The advisory groups eliminated items that they agreed were unlikely to distinguish between CPPD and other forms of arthritis, yielding 127 items for the item-rating exercise. Fifty-six items, most of which had a modal rating of +/- 2 or 3, were retained for future phases. As numerous imaging items were rated +3, the steering committee recommended focusing on imaging of the knee and wrist and 1 additional affected joint for calcification suggestive of CPP crystal deposition. CONCLUSION: A data- and expert-driven process is underway to develop CPPD classification criteria. Candidate items comprise clinical, imaging, and laboratory features.

Prevalence of gout in the adult general population in Spain: Estimating the proportion of undiagnosed cases.

OBJECTIVE: To estimate the prevalence of gout in Spain. METHODS: Cross-sectional, population-based study of people aged 20 years or older. First, randomly selected individuals were contacted by telephone and rheumatic disease screening questionnaires were conducted. If the first screening was positive, medical records were then reviewed and/or a phone questionnaire was conducted by a rheumatologist, followed by an appointment if necessary. Newly diagnosed cases had to fulfil the ACR/EULAR 2015 criteria. To calculate the prevalence and its 95% CI, the sample design was taken into account and weighing was calculated according to age, sex and geographic origin. RESULTS: In all, 4916 individuals were included, 1361 had a positive screening result for gout (59 of them reported a prior diagnosis). Of these, 51 were classified as missing and 95 were classified as gout cases. An additional case was detected through a positive screening for fibromyalgia and Sjögren's syndrome, although a previous gout diagnosis was confirmed by a review of the medical records. Of the 96 gout cases, 31 (32%) were de novo diagnoses. The estimated weighted prevalence of gout was 2.4% (95% CI 1.95-2.95), with a higher prevalence in men (4.55% [95%CI 3.65-5.65]) than women (0.38% [95%CI 0.19-0.76]). CONCLUSION: EPISER2016 is the first population-based study to estimate the prevalence of gout in Spain. Undiagnosed patients accounted for a substantial proportion of cases, highlighting the need for population-approaches when estimating the prevalence of infra-diagnosed diseases. Reliable national approaches are key to obtaining accurate estimates of diseases to better aid healthcare and workforce planning.

Myo-Spain: Spanish Registry of patients with idiopathic inflammatory myopathy. Methodology.

OBJECTIVES: To describe the methods of the Spanish Registry of patients with idiopathic inflammatory myopathy (IIM) (Myo-Spain), as well as its strengths and limitations. The main objective of the project is to analyse the evolution and clinical management of a cohort of patients with IIM. METHODS: Observational, longitudinal, ambispective and multicentre study of a cohort of patients with IIM seen in rheumatology units in Spain. All patients with a diagnosis of IMM will be included in the regular follow-up of the participating centres, regardless of age on initiation of the process. Incident cases will be all patients who at the beginning of the study have been diagnosed for less than 12 months and prevalent cases for more than 12 months. The registry will include data from the visit at baseline, one year and two years. Socio-demographic, clinical, analytical variables, complications, comorbidities, association with other rheumatic diseases, hospital admissions, mortality and treatments will be collected. In addition, indices, scales and questionnaires of activity, muscle involvement, damage, disability, and quality of life will be determined. The recruitment period will be 23 months. The purpose is to obtain a cohort of 400 patients with IMM. CONCLUSIONS: Myo-Spain registry provides the opportunity to develop a cohort of incident and prevalent patients with IMM in Spain. Myo-Spain will be able to assess in detail the clinical characteristics of the disease at different times. The comprehensive information collected during the visits is expected to provide a broad source of data for future analysis.

Dietary supplements for chronic gout.

BACKGROUND: Dietary supplements are frequently used for the treatment of several medical conditions, both prescribed by physicians or self administered. However, evidence of benefit and safety of these supplements is usually limited or absent. OBJECTIVES: To assess the efficacy and safety of dietary supplementation for people with chronic gout. SEARCH METHODS: We updated the original search by searching CENTRAL, MEDLINE, Embase, CINAHL, and four trials registers (August 2020). We applied no date or language restrictions. We also handsearched the abstracts from the 2010 to 2019 American College of Rheumatology and European League against Rheumatism conferences, and checked the references of all included studies. SELECTION CRITERIA: We considered all published randomised controlled trials (RCTs) or quasi-RCTs that compared dietary supplements with no supplements, placebo, another supplement, or pharmacological agents for adults with chronic gout for inclusion. Dietary supplements included, but were not limited to, amino acids, antioxidants, essential minerals, polyunsaturated fatty acids, prebiotic agents, probiotic agents, and vitamins. The major outcomes were acute gout flares, study withdrawal due to adverse events (AEs), serum uric acid (sUA) reduction, joint pain reduction, participant global assessment, total number of AEs, and tophus regression. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: Two previously included RCTs (160 participants) met our inclusion criteria; we did not identify any new trials for this update. As these two trials evaluated different diet supplements (enriched skim milk powder (SMP) and vitamin C) with different outcomes (gout flare prevention for enriched SMP, and sUA reduction for vitamin C), we reported the results separately. One trial (120 participants), at unclear risk of selection and detection bias, compared SMP enriched with glycomacropeptides (GMP) with un-enriched SMP, and with lactose, over three months. Participants were predominantly men, aged in their 50s, who had severe gout. The results for all major outcomes were imprecise, except for pain. None of the results were clinically significant. The frequency of acute gout attacks, measured as the number of flares per month, decreased in all three groups over the three-month study period. The effects of enriched SMP (SMP/GMP/G600) compared with the combined control groups (SMP and lactose powder) at three months in terms of mean number of gout flares per month were not clinically significant (mean (standard deviation (SD)) flares per month: 0.49 (1.52) in SMP/GMP/G60 group versus 0.70 (1.28) in the control groups; absolute risk difference: mean difference (MD) -0.21 flares per month, 95% confidence interval (CI) -0.76 to 0.34; low-quality evidence). The number of withdrawals due to adverse effects was similar between groups (7/40 in SMP/GMP/G600 group versus 11/80 in control groups; (risk ratio (RR) 1.27, 95% CI 0.53 to 3.03); there were 4% more withdrawals in the SMP/lactose groups (10% fewer to 18% more; low-quality evidence). Serum uric acid reduction was similar across groups (mean (SD) -0.025 (0.067) mmol/L in SMP/GMP/G60 group versus -0.010 (0.069) in control groups; MD -0.01, 95% CI -0.04 to 0.01; low-quality evidence). Pain from self-reported gout flares (measured on a 10-point Likert scale) improved slightly more in the GMP/G600 SMP group compared with controls (mean (SD) -1.97 (2.28) in SMP/GMP/G600 group versus -0.94 (2.25) in control groups; MD -1.03, 95% CI -1.89 to -0.17). This was an absolute reduction of 10% (95% CI 20% to 1% reduction; low-quality evidence), which may not be of clinical relevance. The risk of adverse events was similar between groups (19/40 in SMP/GMP/G600 group versus 39/80 in control groups; RR 0.97, 95% CI 0.66 to 1.45); the absolute risk difference was 1% fewer adverse events (1% fewer to 2% more), low-quality evidence). Gastrointestinal events such as nausea, flatulence and diarrhoea were the most commonly reported adverse effects. Data for participant global assessment were not available for analysis; the study did not report tophus regression. One trial (40 participants), at high risk of selection, performance, and detection bias, compared vitamin C alone with allopurinol, and with allopurinol plus vitamin C, in a three-arm study. We only included data from the vitamin C versus allopurinol comparison in this review. Participants were predominantly middle-aged men, and their severity of gout was representative of gout in general. Allopurinol reduced sUA levels more than vitamin C (MD 0.10 mmol/L, 95% CI 0.06 to 0.15), low-quality evidence. The study reported no adverse events; none of the participants withdrew due to adverse events. The study did not assess the rate of gout attacks, joint pain reduction, participant global assessment, or tophus regression. AUTHORS' CONCLUSIONS: While dietary supplements may be widely used for gout, this review found no high-quality that supported or refuted the use of glycomacropeptide-enriched skim milk powder or vitamin C for adults with chronic gout.

EULAR portfolio for Rheumatology training: a EULAR School of Rheumatology initiative.

OBJECTIVE: About half of the rheumatology trainees do not use a portfolio. This project was established to reach consensus about the content of a EULAR portfolio for Rheumatology training and subsequently develop portfolio assessment forms. METHODS: After establishing a portfolio working group (WG), including nine rheumatologists and one educationalist, a systematic literature review (SLR) on the content and structure of portfolios for postgraduate learning was conducted (November 2018). This was followed by a survey among WG members and members of the EMerging EUlar NETwork, inquiring about the content and structure of existing national portfolios. The portfolio WG selected the key components of the portfolio, taking previous experience and feasibility into account. Assessment forms (eg, case-based discussion) were developed and pilot-tested. RESULTS: 13/2034 articles were included in the SLR (12 high/1 moderate risk of bias). Information on procedural skills, personal reflections, learning goals and multisource feedback was most often included a portfolio. Twenty-five respondents completed the survey (response≈50%). Feedback from assessors, reflective writing and formulation of learning goals were considered important dimensions to be covered in a portfolio. Six key components of the portfolio were established: curriculum vitae, personal development plan, clinical work, professional behaviours, education and research activities. Suggested minimal content for each component was formulated. Four assessment forms were successfully pilot-tested by 11 rheumatologists and their trainees. CONCLUSION: A EULAR portfolio for Rheumatology training and assessment forms were developed. Portfolio implementation, particularly in countries without an existing portfolio, may promote a higher standard of rheumatology training across Europe.
