Factors associated with a longer time to access pediatric rheumatologists in Canadian children with juvenile idiopathic arthritis

Rheum for Improvement? Delayed Diagnosis of Juvenile Idiopathic Arthritis: A Narrative Review

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease of childhood and a disease for which we have safe and effective therapies. Early diagnosis of JIA enables timely initiation of therapy and improves long-term disease outcomes. However, many patients with JIA experience prolonged diagnostic delays and have a turbulent course to diagnosis. In this narrative review, we explore the importance of early diagnosis in JIA, what is known about time to diagnosis and diagnostic trajectory, and factors that contribute to delayed diagnosis. We also discuss next steps to improve time to diagnosis for these vulnerable patients.

Diagnosis journey for children with juvenile idiopathic arthritis: a qualitative study

OBJECTIVE

The objective is to explore the journey to diagnosis and referral pathway from the onset of symptoms to the initial assessments at paediatric rheumatology (PR) centres, based on the experience of children with juvenile idiopathic arthritis (JIA) and their parents.

DESIGN

We conducted a qualitative study with semistructured interviews. Our qualitative and phenomenological procedure applied interpretative phenomenological analysis.

PARTICIPANTS

19 families of children diagnosed with JIA 4-24 months before the study began (22 parents, 12 children>11 years), across 4 PR centres.

MAIN OUTCOME MEASURES

The results highlight the contrasting feelings of children and their parents on the referral pathway and interactions with primary care physicians (PCPs).

RESULTS

Four superordinate themes emerged: (1) the journey undertaken by families from initially trivialising the first symptoms to a growing sense of urgency, (2) the perception gap between the families' growing disquiet and first medical interventions, (3) the lack of guidance from physicians prompting parents to initiate action and (4) the various elements of the care pathway that influenced the way the diagnosis was experienced and its impact.

CONCLUSION

The psychosocial consequences of delayed diagnosis in JIA should not be underestimated, especially for adolescents. The views and experiences of children and their parents on the diagnostic journey should be implemented in training programmes and guidelines for PCPs. The development of online supports, integrating the latest medical knowledge with testimonials from families about their experiences, with a common language for physicians and the general population, can facilitate communication and empower families to navigate the healthcare system.

Pre-Rheumatology Referral Consultation and Investigation Pattern in Children with Joint Complaints: Focus on Juvenile Idiopathic Arthritis

The diagnosis of juvenile idiopathic arthritis (JIA) is often entrusted to the pediatric rheumatologist specialist. Timely referral to a specialized center is crucial. This study aims to assess the consultation and investigation patterns of patients with joint complaints before rheumatology referral. This longitudinal cohort study included patients with joint complaints who were referred to the Pediatric Rheumatology Unit. The cohort included 301 patients (58% female), 50 of them (17%) diagnosed with JIA. Compared to patients with orthopedic conditions or functional diseases, JIA patients had seen more specialists (p < 0.01) and received a quicker diagnosis (p < 0.01). Patients with early JIA diagnosis (within 3 months from symptoms onset) were younger (8.46 vs. 11.5 years old; p = 0.04), more frequently female (78% vs. 47%, p = 0.03), and with higher erythrocyte sedimentation rate (ESR) values (37 vs. 9 mm/h; p = 0.02) than those diagnosed later. Patients with a late diagnosis of JIA had a significantly longer median time between the first healthcare visit and the PR referral (25 vs. 101 days; p < 0.01). The main contributor to diagnostic delay in JIA was the time required for PR referral after the first healthcare consult. Younger age, female sex, and higher ESR values were associated with earlier diagnosis of JIA.

Diagnosis of childhood febrile illness using a multi-class blood RNA molecular signature

BACKGROUND

Appropriate treatment and management of children presenting with fever depend on accurate and timely diagnosis, but current diagnostic tests lack sensitivity and specificity and are frequently too slow to inform initial treatment. As an alternative to pathogen detection, host gene expression signatures in blood have shown promise in discriminating several infectious and inflammatory diseases in a dichotomous manner. However, differential diagnosis requires simultaneous consideration of multiple diseases. Here, we show that diverse infectious and inflammatory diseases can be discriminated by the expression levels of a single panel of genes in blood.

METHODS

A multi-class supervised machine-learning approach, incorporating clinical consequence of misdiagnosis as a "cost" weighting, was applied to a whole-blood transcriptomic microarray dataset, incorporating 12 publicly available datasets, including 1,212 children with 18 infectious or inflammatory diseases. The transcriptional panel identified was further validated in a new RNA sequencing dataset comprising 411 febrile children.

FINDINGS

We identified 161 transcripts that classified patients into 18 disease categories, reflecting individual causative pathogen and specific disease, as well as reliable prediction of broad classes comprising bacterial infection, viral infection, malaria, tuberculosis, or inflammatory disease. The transcriptional panel was validated in an independent cohort and benchmarked against existing dichotomous RNA signatures.

CONCLUSIONS

Our data suggest that classification of febrile illness can be achieved with a single blood sample and opens the way for a new approach for clinical diagnosis.

Individual and environmental determinants associated with longer times to access pediatric rheumatology centers for patients with juvenile idiopathic arthritis, a JIR cohort study

BACKGROUND

Despite guidelines, poor access to appropriate care for juvenile idiopathic arthritis (JIA) patients remains a global issue. Prompt referral to a pediatric rheumatology (PR) center and effective care is known to be critical for changing the natural history of the disease and improving long-term prognosis. This project assesses socio-economic factors of delayed referral to a pediatric rheumatologist (PRst) for JIA patients in France and Switzerland within the Juvenile Inflammatory Rheumatism (JIR) Cohort.

METHODS

All patients diagnosed with JIA, presenting at one center of the JIRcohort in France or Switzerland with additional data on referral pathway were included. Patient characteristics at first visit to the PR center, dates of visits to healthcare providers during referral, and parent characteristics were extracted from the JIRcohort database.

RESULTS

Two hundred fifty children were included. The overall median time to first PR assessment was 2.4 months [1.3; 6.9] and ranged widely across the JIA subtypes, from 1.4 months [0.6; 3.8] for children with systemic juvenile idiopathic arthritis (sJIA) to 5.3 months [2.0; 19.1] for children with enthesitis-related arthritis (ERA). A diagnosis of ERA and an appointment with an orthopedist during the referral pathway were significantly associated with a longer time before the first PR visit (hazard ratio HR 0.50 [95% CI: 0.29; 0.84]) and HR 0.68 [95% CI: 0.49; 0.93], respectively) in multivariable analysis. Having a mother with a post-graduate educational attainment level was tendentially associated with a shorter time before the first PR visit, (HR 1.32 [95% CI: 0.99; 1.78]).

CONCLUSIONS

Time to first PRst visit was most often short compared to other studies and close to the British recommendations. However, this time remained too long for many patients. We observed no social inequities in access to a PRst, but we show the need to improve effective pathway and access to a PR center for JIA patients.

Disparities in Pediatric Rheumatic Diseases

Health and health care disparities in pediatric rheumatology are prevalent among socially disadvantaged and marginalized populations based on race/ethnicity, socioeconomic position, and geographic region. These groups are more likely to experience greater disease severity, morbidity, mortality, decreased quality of life, and poor mental health outcomes, which are in part due to persistent structural and institutional barriers, including decreased access to quality health care. Most of the research on health and health care disparities in pediatric rheumatology focuses on juvenile idiopathic arthritis and childhood-onset systemic lupus erythematosus; there are significant gaps in the literature assessing disparities associated with other pediatric rheumatic diseases. Understanding the underlying causes of health care disparities will ultimately inform the development and implementation of innovative policies and interventions on a federal, local, and individual level.

Access to paediatric rheumatology care in juvenile idiopathic arthritis: what do we know? A systematic review

OBJECTIVE

This review examines time to access appropriate care for JIA patients and analyses the referral pathway before the first paediatric rheumatology (PR) visit. We also describe factors associated with a longer referral.

METHODS

We performed a systematic literature review, screening electronic databases (PubMed, Web of Science, EMBASE, Cochrane library and Open Grey database) up to February 2020. Articles written before 1994 (i.e. before the introduction of the unifying term JIA) were excluded.

RESULTS

From 595 nonduplicate citations found, 15 articles were finally included in the review. Most of the studies took place in Europe. The median time to first PR visit ranged from 3 to 10 months, with some disparities between referral pathway and patient characteristics. Patients with systemic-onset JIA had the shortest time to referral. Some clinical and biological factors such as swelling, fever, and elevated CRP and/or ESR were associated with a shorter time to first PR visit. Conversely, enthesitis, older age at symptom onset or pain were associated with a longer time. Whatever the country or world region, and despite disparities in healthcare system organization and healthcare practitioner availabilities, times to access PR were not wide-ranging.

CONCLUSION

This is the first systematic review to summarize research on access to PR for JIA patients. The pathway of care for JIA patients remains complex, and reasons for delayed referral depend on several factors. Standardized clinical guidelines and fast-track pathways to facilitate prompt referral to specialized teams have to allow for worldwide disparities in healthcare provision.

Patient factors associated with waiting time to pediatric rheumatologist consultation for patients with juvenile idiopathic arthritis

BACKGROUND

Early diagnosis and treatment of Juvenile Idiopathic Arthritis (JIA) is essential to optimize outcomes. Wait times (WTs) to consultation with a pediatric rheumatologist consultation is a Canadian quality measure, with benchmarks set at 7 days for systemic JIA (sJIA) and 4 weeks for other JIA categories. In this study we assess WTs for JIA at a single academic center and describe factors associated with longer WTs.

METHODS

This was a retrospective cohort study of 164 patients enrolled in a pharmacogenetic study in Alberta between 2002 and 2018. Limited chart reviews were conducted to evaluate dates of referral and first rheumatology visit to calculate WTs for receipt of pediatric rheumatology care. Cox proportional hazard models identified factors associated with WTs considering variables at the first pediatric rheumatology visit including: JIA category, age, sex, distance to the pediatric rheumatology clinic, number of active joints, pain and C-reactive protein.

RESULTS

The median age at diagnosis was 8.0 years (interquartile range, IQR 3.5, 12.0) and 46% of patients had oligoarticular JIA. Only 18 patients (11%) were from rural locations. The median WT for all patients met the national benchmark (22 days, IQR, 9, 44) with no statistically significant difference between WTs among JIA categories (p = 0.055). Importantly, the majority of sJIA cases met the 7-day benchmark (67%) with a median WT of 1.5 days. Older age was associated with longer WT (HR 0.94, 95% CI 0.89, 0.98, p = 0.005).

CONCLUSION

Median benchmarks were met, however delays in older patients highlight the need for monitoring WTs.

Factors impacting referral of JIA patients to a tertiary level pediatric rheumatology center in North India: a retrospective cohort study

BACKGROUND

JIA studies demonstrate that there is a "window of opportunity" early in the disease course during which appropriate management improves outcomes. No data is available regarding patients' pathway, before first pediatric rheumatology (PR) evaluation in India, a country where health-care costs are self- paid by patients and where a significant shortage of pediatric rheumatologists (PRsts) is known. This study aimed to describe time from onset of symptoms to first PR visit of JIA patients to a tertiary center in India and factors that impact this.

METHODS

This retrospective study is from data collected at the PR center, Sir Ganga Ram Hospital (SGRH) in New Delhi. JIA patients fulfilling ILAR 2004 criteria and seen at least twice from 1st October 2013 to 30th September 2018 were included. Data collected were: demographic details, history of disease, referral practitioner, clinical and laboratory features, treatments. Mann-Whitney U-test, Chi square and logistic regression were used as appropriate to study factors that determined time to first PR visit.

RESULTS

Five hundred and twenty patients were included: 396 were diagnosed at this PR center (group A), 124 were previously diagnosed as JIA and managed by non PRsts before first PR visit (group B). Median time from symptom onset to first PR visit was 4.1 months and median distance travelled 119.5 km. Despite ongoing treatment, group B patients had more aggressive disease and resided further away as compared to Group A patients. On univariate analysis, factors that predicted PR visit within 3 months were private patients, short distance to travel, family history of inflammatory disease, history of fever, history of acute uveitis or high ESR. On multivariate analysis all these factors were significant except high ESR and acute uveitis.

CONCLUSION

Time to first PR assessment at this center was comparable to that seen in western countries. Cost of care and long distance to the center delayed consultation; acuity of complaints and family history of rheumatologic condition hastened referral. Possible solutions to improve referral to PR centers would be to increase the number of PRsts and to improve medical insurance coverage.

Testing population-based performance measures identifies gaps in juvenile idiopathic arthritis (JIA) care

BACKGROUND

The study evaluates Performance Measures (PMs) for Juvenile Idiopathic Arthritis (JIA): The percentage of patients with new onset JIA with at least one visit to a pediatric rheumatologist in the first year of diagnosis (PM1); and the percentage of patients with JIA under rheumatology care seen in follow-up at least once per year (PM2).

METHODS

Validated JIA case ascertainment algorithms were used to identify cases from provincial health administrative databases in Manitoba, Canada in patients < 16 years between 01/04/2005 and 31/03/2015. PM1: Using a 3-year washout period, the percentage of incident JIA patients with ≥1 visit to a pediatric rheumatologist in the first year was calculated. For each fiscal year, the proportion of patients expected to be seen in follow-up who had a visit were calculated (PM2). The proportion of patients with gaps in care of > 12 and > 14 months between consecutive visits were also calculated.

RESULTS

One hundred ninety-four incident JIA cases were diagnosed between 01/04/2008 and 03/31/2015. The median age at diagnosis was 9.1 years and 71% were female. PM1: Across the years, 51-81% of JIA cases saw a pediatric rheumatologist within 1 year. PM2: Between 58 and 78% of patients were seen in yearly follow-up. Gaps > 12, and > 14, months were observed once during follow-up in 52, and 34%, of cases, and ≥ twice in 11, and 5%, respectively.

CONCLUSIONS

Suboptimal access to pediatric rheumatologist care was observed which could lead to diagnostic and treatment delays and lack of consistent follow-up, potentially negatively impacting patient outcomes.

Medical pathways of children with juvenile idiopathic arthritis before referral to pediatric rheumatology centers

OBJECTIVE

A better understanding about the referral pathway of patients suffering from juvenile idiopathic arthritis (JIA) is required The aim of this study was to describe and analyze time from onset of symptoms to first pediatric rheumatology (PR) visit and the referral pathway of children with incident JIA in two French competence centers.

METHODS

From October 2009 to October 2017, new JIA patients were registered in the "Auvergne-Loire cohort on JIA". We collected referral pathway, symptom onset, biological and clinical data at first assessment in PR department.

RESULTS

In all, 111 children were included. Median time to first PR visit was 3.3 months [interquartile range (IQR) 1.3, 10.7] with a significant difference between JIA subtypes. After exclusion of systemic JIA, older age at onset of symptoms, and presence of enthesitis or joint pain were significantly associated with a longer time to first PR visit, while joint swelling or limping, abnormal ESR or CRP were associated with a shorter time. The median number of health care practitioners met was 3 [IQR 3, 4]. Orthopedists referred children to a PR center in 64% of cases, pediatricians in 50%, emergency care practitioners in 27% and general practitioners in 25%. Although non-systemic JIAs are not an emergency, 45% were referred to the emergency room.

CONCLUSION

Time to first PR visit is rather short compared to other countries but remains too long. Pediatric rheumatologists should offer primary care providers basic training on JIA and fast direct access to PR departments if JIA is suspected.

Sociocultural Considerations in Juvenile Arthritis: A Review

PROBLEM

Juvenile Arthritis (JA) is one of the most common autoimmune diseases in children. A variety of sociocultural factors that influence health outcomes in children with JA have been examined in previous research. However, clinical guidelines to guide the care of these children lack support because this research has not been systematically examined and synthesized.

ELIGIBILITY CRITERIA

Primary research articles from five internet databases were included if they were peer-reviewed articles in English of studies conducted in the U.S. or Canada and referenced one or more determinants of health, quality of life, socioeconomic status, or health disparities in children with JA.

SAMPLE

The final sample included 16 articles representing 2139 children and 939 parents.

RESULTS

Topics covered in the studies included medication compliance, electronic medical records, environmental risk factors, economic hardship, parental coping, leisure activities, and their effects on patient outcomes including disability and quality of life. Patients with Medicaid experienced more severe outcomes than patients with private insurance despite equivalent levels of healthcare utilization. Other important topics, such as effects of the physical environment and alcohol use, were missing from the literature.

CONCLUSIONS

Five categories of health determinants were found to influence outcomes: biology, individual behaviors, social environment, physical environment, and health services. Disparities continue to exist for racial and ethnic minority children with JA and those of low socioeconomic status.

IMPLICATIONS

Sociocultural factors should be taken into consideration when developing care plans, research studies, and policies in order to remove barriers and promote the best outcomes for this vulnerable population.

Access to pediatric rheumatology care for Juvenile Idiopathic Arthritis in the United Arab Emirates

BACKGROUND

This study looks at access to care for Juvenile Idiopathic Arthritis through pediatric rheumatology in the UAE, as an example of multi-ethnic society.

METHODS

Patients with a diagnosis of Juvenile idiopathic arthritis were identified through the hospital electronic medical records system from January 1st 2011 to December 31st 2014. All residents of the United Arab Emirates hold an Emirates identity card. We divided our patients into two groups: Emirati-Emirates, who are native Emirati children and hold the Emirati nationality, as stated on their Emirates identity card, and who therefore have full, comprehensive access to free medical care; and non-Emirati-Emirates, who represent other nationalities, as stated on their Emirates identity card. The primary objective of this study is to look at access to care for Juvenile idiopathic arthritis through pediatric rheumatology in the two groups. The secondary objective is to look at the effect of having multiple types of healthcare insurance coverage on access to biologics. A retrospective review was carried out.

RESULTS

Sixty-six patients with JIA identified: 33 Emirates and 33 non-Emirates. For Emirates, the mean time from onset to first appointment with pediatric rheumatologist and diagnosis is 9 months (range: 1-48), and for non-Emirates is 12.4 months (range: 1-96). Among the Emirates, 10 patients are currently on biologic with methotrexate. Among the non-Emirates, 15 are on biologic with methotrexate. Among the Emirates, 12 are currently in remission while on treatment, as are 10 non-Emirates. Regarding disability, one Emirati patient has blindness secondary to noncompliance while under previous treatment. One Non-Emirati developed joint deformities due to periods of noncompliance and no follow up.

CONCLUSIONS

Delay in presentation to pediatric rheumatology has been identified as an important factor in our population, which is multi-cultural and multi-ethnic. Type of health care insurance cover did not affect number of patients getting biological therapy once patient seen in the pediatric rheumatology service.

A recurring rollercoaster ride: a qualitative study of the emotional experiences of parents of children with juvenile idiopathic arthritis

BACKGROUND

Despite the wealth of clinical research carried out in children with juvenile idiopathic arthritis (JIA), little is known about the emotional experiences of their parents. This article describes the predominant emotional experiences reported by parents of children with JIA in two Canadian cities.

METHODS

Research participants included 15 experienced parents and 8 novice parents (<6 months since children's JIA diagnosis). Their children were 2 to 16 years old with various JIA categories. A qualitative dataset including audio recordings and verbatim transcripts of three focus groups, and written reports of 59 reciprocal interviews (parents interviewing each other) were examined by a multidisciplinary research team following a four-step qualitative analytical process.

RESULTS

Parents of children with JIA experienced recurrent mixed negative and positive emotions that varied over time. Between disease onset and diagnosis, mounting anxiety, fear and confusion were the predominant emotions. Shortly after diagnosis there were shock, disbelief, and fear, with a sense of having being blindsided by the disease. At times of disease quiescence there was hope and gratitude, but also fatigue and frustration with ongoing treatment and fear of flares. During periods of increasing or ongoing symptoms there was admiration and sympathy for the courageous way children coped with JIA, as well as sorrow and frustration for ongoing pain and limitations. There were at times, frustration and indignation with peers and teachers unable to understand the child's fluctuations in physical activity and schoolwork. Throughout the disease, parents felt an underlying anxiety and powerlessness.

CONCLUSIONS

Parents of children with JIA described complex emotional journeys akin to the recurring ups and downs of rollercoaster rides, instead of ordered emotional phases ending in resolution. This has implications for healthcare providers who need to be aware of the complexity of these emotional journeys to support parents more effectively, thereby helping improve patient outcomes.

The association between low socioeconomic status with high physical limitations and low illness self-perception in patients with juvenile idiopathic arthritis: results from the Childhood Arthritis Prospective Study

Objective

To examine the association between socioeconomic status (SES) and delay to a pediatric rheumatology clinic, disease severity, and illness perception in patients with juvenile idiopathic arthritis in England.

Methods

Using the Index of Multiple Deprivation, 923 consecutive children from the Childhood Arthritis Prospective Study were assigned to SES groups: high‐SES (19.1%), middle‐SES (44.5%), or low‐SES (36.4%). At baseline, disease activity was assessed, and the Childhood Health Assessment Questionnaire (C‐HAQ), the Illness Perception Questionnaire, and the Child Health Questionnaire, version Parent Form 50, were completed. Linear median regression analyses or zero‐inflated negative binominal (ZINB) regression analyses were used.

Results

Delay to first pediatric rheumatology consultation was the same between the 3 SES groups. Although disease activity scores assessed by the pediatric rheumatologist did not differ between the 3 SES groups, persons in the low‐SES group recorded higher C‐HAQ scores compared to the high‐SES group (zero‐inflated part of ZINB odds ratio 0.28 [95% confidence interval (95% CI) 0.14, 0.55], count part of ZINB β 0.26 [95% CI 0.05, 0.48]). Parents with low SES also reported more often that their children's school work or activities with friends had been limited. Furthermore, the low‐SES group had a worse perception about the consequences of the disease and the effect of treatment than those in the high‐SES group.

Conclusion

Patients from a low‐SES background report more problems with daily activities and have a lower perception of the consequences of the disease than patients from a high‐SES background, warranting special attention from a multidisciplinary team.

The clinical spectrum of juvenile idiopathic arthritis in a large urban population

Urban populations present particular challenges for medical providers. Patients are extremely diverse, with varied socioeconomic, cultural, and ethnic backgrounds. Physicians caring for children with juvenile idiopathic arthritis must be prepared to interact effectively with many types of families who bring with them varied experiences and expectations. Pediatric rheumatologists should be familiar with patient characteristics that can influence disease outcomes. Access to care is affected by place of residence, referral delays, parental education, and the child’s insurance status. Patients of different ethnic backgrounds vary in their trust of physicians and health systems. Understanding of risk in medical decision making is influenced by ethnicity as well. Adherence also varies by ethnic group, with African American patients reporting lower adherence than Caucasian patients. Issues of doctor– patient communication and use of complementary and alternative medicine are also affected by cultural factors. Especially for physicians working in a large metropolitan area, an understanding of societal factors influencing patient behavior is essential to provide optimal care for children with juvenile idiopathic arthritis.
