ObjectiveSince 2010, the rheumatology community has developed guidelines and tools to improve healthcare transition. In this study, we aimed to compare current transition practices and beliefs among Childhood Arthritis and Rheumatology Research Alliance (CARRA) rheumatology providers with transition practices from a provider survey published in 2010.MethodsIn 2018, CARRA members completed a 25-item online survey about healthcare transition. Got Transition’s Current Assessment of Health Care Transition Activities was used to measure clinical transition processes on a scale of 1 (basic) to 4 (comprehensive). Bivariate analyses were used to compare 2010 and 2018 survey findings.ResultsOver half of CARRA members completed the survey (202/396), including pediatric rheumatologists, adult- and pediatric-trained rheumatologists, pediatric rheumatology fellows, and advanced practice providers. The most common target age to begin transition planning was 15–17 years (49%). Most providers transferred patients prior to age 21 years (75%). Few providers used the American College of Rheumatology transition tools (31%) or have a dedicated transition clinic (23%). Only 17% had a transition policy in place, and 63% did not consistently address healthcare transition with patients. When compared to the 2010 survey, improvement was noted in 3 of 12 transition barriers: availability of adult primary care providers, availability of adult rheumatologists, and pediatric staff transition knowledge and skills (P < 0.001 for each). Nevertheless, the mean current assessment score was < 2 for each measurement.ConclusionThis study demonstrates improvement in certain transition barriers and practices since 2010, although implementation of structured transition processes remains inconsistent.

Objective.To assess North American pediatric rheumatology providers’ perspectives on practices, barriers, and opportunities concerning the transition from pediatric-centered to adult-centered care.Methods.Childhood Arthritis and Rheumatology Research Alliance (CARRA) members completed a 25-item survey assessing current transition practices, transition policy awareness, and transitional care barriers and needs. Results were compared to the American Academy of Pediatrics (AAP) 2008 survey on transitional care.Results.Over half (158/288, 55%) of CARRA members completed the survey. Fewer than 10% are very familiar with AAP guidelines about transition care for youth with special healthcare needs. Eight percent have a formal written transition policy, but 42% use an informal approach. Patient request (75%) most frequently initiates transfer to adult care. Two major barriers to transition are fragmented adult medical care and lack of sufficient time to provide services. Compared with AAP survey participants, pediatric rheumatology providers are significantly more likely to help youth find an adult specialist (63% vs 45%) and discuss confidentiality and consent before age 18 (45% vs 33%), but are less likely to help with medical summary creation (16% vs 27%) or find a primary care provider (25% vs 47%). Outcomes ranked as “very important” in defining a successful transition are survival (76%), seeing an adult rheumatologist within 6 months of final pediatric rheumatology visit (66%), and maintaining insurance coverage (57%).Conclusion.This comprehensive survey of North American pediatric rheumatology providers regarding transitional care practices demonstrates deficiencies in education, resources, and a formalized process. Respondents support development of standardized rheumatology-specific transition practices.

Objective.Granulomatosis with polyangiitis (Wegener’s; GPA) and other antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are rare in childhood and are sometimes difficult to discriminate. We compared use of adult-derived classification schemes for GPA against validated pediatric criteria in the ARChiVe (A Registry for Childhood Vasculitis e-entry) cohort, a Childhood Arthritis and Rheumatology Research Alliance initiative.Methods.Time-of-diagnosis data for children with physician (MD) diagnosis of AAV and unclassified vasculitis (UCV) from 33 US/Canadian centers were analyzed. The European Medicines Agency (EMA) classification algorithm and European League Against Rheumatism/Paediatric Rheumatology International Trials Organisation/Paediatric Rheumatology European Society (EULAR/PRINTO/PRES) and American College of Rheumatology (ACR) criteria for GPA were applied to all patients. Sensitivity and specificity were calculated (MD-diagnosis as reference).Results.MD-diagnoses for 155 children were 100 GPA, 25 microscopic polyangiitis (MPA), 6 ANCA-positive pauciimmune glomerulonephritis, 3 Churg-Strauss syndrome, and 21 UCV. Of these, 114 had GPA as defined by EMA, 98 by EULAR/PRINTO/PRES, and 87 by ACR. Fourteen patients were identified as GPA by EULAR/PRINTO/PRES but not by ACR; 3 were identified as GPA by ACR but not EULAR/PRINTO/PRES. Using the EMA algorithm, 135 (87%) children were classifiable. The sensitivity of the EMA algorithm, the EULAR/PRINTO/PRES, and ACR criteria for classifying GPA was 90%, 77%, and 69%, respectively, with specificities of 56%, 62%, and 67%. The relatively poor sensitivity of the 2 criteria related to their inability to discriminate patients with MPA.Conclusion.EULAR/PRINTO/PRES was more sensitive than ACR criteria in classifying pediatric GPA. Neither classification system has criteria for MPA; therefore usefulness in discriminating patients in ARChiVe was limited. Even when using the most sensitive EMA algorithm, many children remained unclassified.

Objective.There are no validated tools for measuring disease activity in pediatric vasculitis. The Birmingham Vasculitis Activity Score (BVAS) is a valid disease activity tool in adult vasculitis. Version 3 (BVAS v.3) correlates well with physician’s global assessment (PGA), treatment decision, and C-reactive protein in adults. The utility of BVAS v.3 in pediatric vasculitis is not known. We assessed the association of BVAS v.3 scores with PGA, treatment decision, and erythrocyte sedimentation rate (ESR) at diagnosis in pediatric antineutrophil cytoplasmic antibody-associated vasculitis (AAV).Methods.Children with AAV diagnosed between 2004 and 2010 at all ARChiVe centers were eligible. BVAS v.3 scores were calculated with a standardized online tool (www.vasculitis.org). Spearman’s rank correlation coefficient (rs) was used to test the strength of association between BVAS v.3 and PGA, treatment decision, and ESR.Results.A total of 152 patients were included. The physician diagnosis of these patients was predominantly granulomatosis with polyangiitis (n = 99). The median BVAS v.3 score was 18.0 (range 0–40). The BVAS v.3 correlations were rs = 0.379 (95% CI 0.233 to 0.509) with PGA, rs = 0.521 (95% CI 0.393 to 0.629) with treatment decision, and rs = 0.403 (95% CI 0.253 to 0.533) with ESR.Conclusion.Applied to children with AAV, BVAS v.3 had a weak correlation with PGA and moderate correlation with both ESR and treatment decision. Prospective evaluation of BVAS v.3 and/or pediatric-specific modifications to BVAS v.3 may be required before it can be formalized as a disease activity assessment tool in pediatric AAV.

Objective.To determine the elapsed time while receiving aggressive therapy to the first observation of clinically inactive disease (CID), total duration of CID and potential predictors of this response in a cohort of children with recent onset of polyarticular juvenile idiopathic arthritis (poly-JIA).Methods.Eighty-five children were randomized blindly to methotrexate (MTX), etanercept, and rapidly tapered prednisolone (MEP) or MTX monotherapy and assessed for CID over 1 year of treatment. Patients who failed to achieve intermediary endpoints were switched to open-label MEP treatment.Results.Fifty-eight (68.2%) of the 85 patients achieved CID at 1 or more visits including 18 who received blinded MEP, 11 while receiving MTX monotherapy, and 29 while receiving open-label MEP. Patients starting on MEP achieved CID earlier and had more study days in CID compared to those starting MTX, but the differences were not significantly different. Patients given MEP (more aggressive therapy) earlier in the disease course were statistically more likely to have a higher proportion of followup visits in CID than those with longer disease course at baseline. Those who achieved American College of Rheumatology Pediatric 70 response at 4 months had a significantly greater proportion of followup visits in CID, compared to those who failed to achieve this improvement (p < 0.0001). Of the 32 patients who met criteria for CID and then lost CID status, only 3 fulfilled the definition of disease flare.Conclusion.Shorter disease duration prior to treatment, a robust response at 4 months, and more aggressive therapy result in a higher likelihood and longer duration of CID in patients with poly-JIA. The original trial from which data for this analysis were obtained is registered on www.clinicaltrials.gov NCT 00443430.

Objective.To determine whether adult disease severity subclassification systems for antineutrophil cytoplasmic antibody-associated vasculitis (AAV) are concordant with the decision to treat pediatric patients with cyclophosphamide (CYC).Methods.We applied the European Vasculitis Study (EUVAS) and Wegener’s Granulomatosis Etanercept Trial (WGET) disease severity subclassification systems to pediatric patients with AAV in A Registry for Childhood Vasculitis (ARChiVe). Modifications were made to the EUVAS and WGET systems to enable their application to this cohort of children. Treatment was categorized into 2 groups, “cyclophosphamide” and “no cyclophosphamide.” Pearson’s chi-square and Kendall’s rank correlation coefficient statistical analyses were used to determine the relationship between disease severity subgroup and treatment at the time of diagnosis.Results.In total, 125 children with AAV were studied. Severity subgroup was associated with treatment group in both the EUVAS (chi-square 45.14, p < 0.001, Kendall’s tau-b 0.601, p < 0.001) and WGET (chi-square 59.33, p < 0.001, Kendall’s tau-b 0.689, p < 0.001) systems; however, 7 children classified by both systems as having less severe disease received CYC, and 6 children classified as having severe disease by both systems did not receive CYC.Conclusion.In this pediatric AAV cohort, the EUVAS and WGET adult severity subclassification systems had strong correlation with physician choice of treatment. However, a proportion of patients received treatment that was not concordant with their assigned severity subclass.

To the Editor: We appreciate the contribution of Dr. Chanchlani, et al regarding their retrospective assessment of transfer of adolescent rheumatology patients in the United Kingdom because it demonstrated the real-world challenges of implementing a successful transition program1. The UK has always been a leader in rheumatology adolescent transitional care as noted by this group’s previous work2. While their recent data showed favorable results in actual transfers, as noted by adult rheumatology referral notes being sent to the pediatric rheumatology consultant (86%), concerns were raised with regard to … Address correspondence to Dr. P.
