Higher concentrations of vitamin D in Canadian children with juvenile idiopathic arthritis compared to healthy controls are associated with more frequent use of vitamin D supplements and season of birth.

A number of studies have demonstrated that patients with autoimmune disease have lower levels of vitamin D prompting speculation that vitamin D might suppress inflammation and immune responses in children with juvenile idiopathic arthritis (JIA).  The objective of this study was to compare vitamin D levels in children with JIA at disease onset with healthy children. We hypothesized that children and adolescents with JIA have lower vitamin D levels than healthy children and adolescents. Data from a Canadian cohort of children with new-onset JIA (n= 164, data collection 2007-2012) were compared to Canadian Health Measures Survey (CHMS) data (n=4027, data collection 2007-2011). We compared 25-hydroxy vitamin D (25(OH)D) concentrations with measures of inflammation, vitamin D supplement use, milk intake, and season of birth. Mean 25(OH)D level was significantly higher in patients with JIA (79 ± 3.1 nmol/L) than in healthy controls (68 ± 1.8 nmol/L P <.05). Patients with JIA more often used vitamin D containing supplements (50% vs. 7%; P <.05). The prevalence of 25(OH)D deficiency (<30 nmol/L) was 6% for both groups. Children with JIA with 25(OH)D deficiency or insufficiency (<50 nmol/L) had higher C-reactive protein levels. Children with JIA were more often born in the fall and winter compared to healthy children. In contrast to earlier studies, we found vitamin D levels in Canadian children with JIA were higher compared to healthy children and associated with more frequent use of vitamin D supplements. Among children with JIA, low vitamin D levels were associated with indicators of greater inflammation.

Development and Acceptability of a Patient Decision Aid for Pain Management in Juvenile Idiopathic Arthritis: The JIA Option Map.

BACKGROUND: Youths with juvenile idiopathic arthritis (JIA) often experience pain, which reduces their quality of life. A diversity of pain management options exists for these patients, but few discussions happen in clinical settings. Our team is developing a web-based patient decision aid (PDA) to help youths with JIA, parents, and their health care providers (HCPs) make informed and preference-based decisions about pain management options. OBJECTIVE: The objective of this study was to develop a paper-based prototype of the web-based PDA and to assess its acceptability. METHODS: We developed a paper-based prototype of the PDA, called the JIA Option Map, using an iterative process following the International Patient Decision Aid Standards and based on the Ottawa Decision Support Framework. We held three consensus meetings and a follow-up online survey followed by discussions among team members to agree on the format and content of the PDA. We then evaluated acceptability through interviews with 12 youth with JIA (aged 8-18 years), 12 parents, and 11 HCPs. Participants from rheumatology clinics in Canada and the USA reviewed the PDA and assessed its usefulness, content, and format. Interviews were audiotaped, transcribed verbatim, and analyzed using simple descriptive content analysis. RESULTS: The PDA contains an assessment of pain and current treatments, a values-clarification exercise, a list of 33 treatment options with evidence-based information, and a goal-setting exercise. All participants agreed that it would be a useful tool for making decisions about pain management. Participants appreciated the incorporation of scientific evidence and visuals to demonstrate the benefits of treatment options but suggested describing the source of the evidence more thoroughly. Participants suggested adding complementary medicine and nutrition to the available treatment options and removing options that are primarily used to reduce inflammation. Most participants preferred an interactive web-based version of the PDA that would show a few options consistent with their preferences, followed by a discussion with HCPs. CONCLUSION: The PDA was deemed acceptable to all participants, with a few modifications. This feedback was used to improve the PDA by simplifying and clarifying the information and adjusting the number of treatment options presented. Work is underway to develop an interactive web-based version with an algorithm to present options tailored to each user.

Youths with juvenile idiopathic arthritis (JIA) often feel pain and try many pain treatments such as medications and physical or psychological treatments. Choosing treatments can be hard for families, and health care providers do not always provide information on pain treatments. Our team is developing the JIA Option Map, a tool that presents information on pain treatments based on personal preferences. The tool takes patients through a five-step process where they describe their pain, express their preferences, and learn about more than 30 pain treatments. Patients can then choose treatments and make a plan to use them. This paper explains how a paper-based version of the tool was developed and whether it is suitable for youths, parents, and health care providers. The tool was developed by holding meetings with youths with JIA, health care providers, and researchers to agree on the content and format. We also interviewed youths with JIA, parents, and health care providers to test whether it was suitable. All participants felt that the tool was suitable and that it would be useful for making decisions about pain treatments. Participants liked the idea of using a web-based tool with coaching by health care providers. Work is underway to develop this improved version of the JIA Option Map.

Development and Preliminary Face and Content Validation of the "Which Health Approaches and Treatments Are You Using?" (WHAT) Questionnaires Assessing Complementary and Alternative Medicine Use in Pediatric Rheumatology.

OBJECTIVE: Complementary and alternative medicine (CAM) is commonly used by children with juvenile idiopathic arthritis (JIA), yet no validated questionnaires assess that use. The objective of this study was to develop child self- and parent proxy-report questionnaires assessing CAM use and to determine the face and content validity of the "Which Health Approaches and Treatments are you using?" (WHAT) questionnaires in pediatric rheumatology. METHODS: A sequential phased mixed methods approach was used to develop the questionnaires. A Delphi Survey of 126 experts followed by an interdisciplinary consensus conference of 14 stakeholders in CAM, general pediatrics and pediatric rheumatology was held to develop consensus on the content of the questionnaires using a nominal group technique. To determine face and content validity of the questionnaires, two groups, including (a) a purposive sample of 22 children with JIA 8 to 18 years and their parents from the Children's Hospital of Eastern Ontario and the Hospital for Sick Children, and (b) 21 Canadian pediatric rheumatology experts, participated in interviews. Participants were independently asked about the goal, understandability and comprehensiveness of the WHAT questionnaires, as well as the relevance of items. RESULTS: Consensus was reached on 17 items of the WHAT questionnaires. The domains found to be relevant were child's CAM use, factors associated with CAM use, perceived impact of CAM use, and communication about CAM. A total of 15 items in the parent proxy-report questionnaire and 13 items in the child report questionnaire showed adequate content validity. CONCLUSIONS: Consensus was reached by experts on the content of a pediatric CAM questionnaire. Face and content validity testing and modifications made to the WHAT questionnaires have helped ensure adequate preliminary validity for use in pediatric rheumatology. This constitutes the basis for further testing of these questionnaires in pediatric rheumatology and for adaptation to other chronic diseases.

Measurement properties of questionnaires assessing complementary and alternative medicine use in pediatrics: a systematic review.

OBJECTIVE: Complementary and alternative medicine (CAM) is commonly used by children, but estimates of that use vary widely partly due to the range of questionnaires used to assess CAM use. However, no studies have attempted to appraise measurement properties of these questionnaires. The aim of this systematic review was to critically appraise and summarize measurement properties of questionnaires of CAM use in pediatrics. STUDY DESIGN: A search strategy was implemented in major electronic databases in March 2011 and conference websites, scientific journals and experts were consulted. Studies were included if they mentioned a questionnaire assessing the prevalence of CAM use in pediatrics. Members of the team independently rated the methodological quality of the studies (using the COSMIN checklist) and measurement properties of the questionnaires (using the Terwee and Cohen criteria). RESULTS: A total of 96 CAM questionnaires were found in 104 publications. The COSMIN checklist showed that no studies reported adequate methodological quality. The Terwee criteria showed that all included CAM questionnaires had indeterminate measurement properties. According to the Cohen score, none were considered to be a well-established assessment, two approached the level of a well-established assessment, seven were promising assessments and the remainder (n = 87) did not reach the score's minimum standards. CONCLUSION: None of the identified CAM questionnaires have been thoroughly validated. This systematic review highlights the need for proper validation of CAM questionnaires in pediatrics, which may in turn lead to improved research and knowledge translation about CAM in clinical practice.

Usability testing of an online self-management program for adolescents with juvenile idiopathic arthritis.

BACKGROUND: A new bilingual (English and French) Internet-based self-management program, Teens Taking Charge: Managing Arthritis Online, for adolescents with arthritis and their parents was developed following a needs assessment. OBJECTIVES: This study explored the usability (user performance and satisfaction) of the self-management program for youth with juvenile idiopathic arthritis (JIA) and their parents to refine the health portal prototype. METHODS: A qualitative study design with semi-structured, audio taped interviews and observation by a trained observer was undertaken with two iterative cycles to determine the usability (ease of use, efficiency, errors, and user satisfaction) of the user interface and content areas of the intervention. A purposive sample of English-speaking (n = 11; mean age = 15.4, standard deviation [SD] 1.7) and French-speaking (n = 8; mean age = 16.0, SD 1.2) adolescents with JIA and one of their respective parents/caregivers were recruited from 2 Canadian tertiary care centers. Descriptive statistics and simple content analyses were used to organize data into categories that reflected the emerging usability themes. RESULTS: All of the participants had access to a computer/Internet at home; however, adolescents were more comfortable using the computer/Internet than their parents. Adolescents and parents provided similar as well as differing suggestions on how the website user interface could be improved in terms of its usability (navigation; presentation and control usage errors; format and layout; as well as areas for further content development). There were no major differences in usability issues between English- and French-speaking participants. Minor changes to the website user interface were made and tested in a second cycle of participants. No further usability problems were identified in the second iterative cycle of testing. Teens and parents responded positively to the appearance and theme of the website (ie, promoting self-management) and felt that it was easy to navigate, use, and understand. Participants felt that the content was appropriate and geared to meet the unique needs of adolescents with JIA and their parents as well as English- and French-speaking families. Many participants responded that the interactive features (discussion board, stories of hope, and video clips of youth with JIA) made them feel supported and "not alone" in their illness. CONCLUSIONS: We describe the usability testing of a self-management health portal designed for English- and French-speaking youth with arthritis and their parents, which uncovered several usability issues. Usability testing is a crucial step in the development of self-management health portals to ensure that the various end users (youth and parents) have the ability to access, understand, and use health-related information and services that are delivered via the Internet and that they are delivered in an efficient, effective, satisfying, and culturally competent manner.

Is complementary and alternative healthcare use associated with better outcomes in children with juvenile idiopathic arthritis?

OBJECTIVE: The objectives of this study were (1) to examine the association between the use of complementary and alternative healthcare (CAHC) and subsequent health outcomes; and (2) to explore the association between CAHC use and adherence to conventional treatments in children with juvenile idiopathic arthritis (JIA). METHODS: A cohort of children with JIA (n = 182, mean age 10 yrs) who attended outpatient clinics were followed for one year. We evaluated the use of CAHC, health-related quality of life (HRQOL), global health, physical functioning, pain, and disease severity at 3-month intervals. We also evaluated perceived adherence to treatments. General estimating equations were performed to determine the association between use of CAHC and subsequent outcomes while controlling for possible confounders. RESULTS: CAHC was used by 36.4% of participants over the 12-month period. Use of CAHC was associated with subsequent lower global health and physical functioning despite higher adherence to prescribed medications as assessed by the rheumatologist (p < 0.05). Use of CAHC was not associated with subsequent improved HRQOL or decreased pain or disease severity. CONCLUSION: Children with JIA who use CAHC do not have improved outcomes, at least over the relatively short term. Nevertheless, they seem to be more adherent to conventional treatment according to the rheumatologist.

Longitudinal analysis of complementary and alternative health care use in children with juvenile idiopathic arthritis.

OBJECTIVES: The aims were to determine the frequency of use of different types of complementary and alternative health care (CAHC) in children with juvenile idiopathic arthritis (JIA), to evaluate their effectiveness from the parents' point of view and to explore the factors associated with utilization and with continued use. METHODS: A cohort of children with JIA (n=182, mean age: 10 years) who attended out-patient clinics were followed for 1 year. Parents responded to questionnaires every 3 months. We used generalized estimating equations to analyze factors associated with CAHC use and polytomous regression to evaluate factors associated with continued use of CAHC. RESULTS: Use of CAHC ranged between 10% and 24% for the various 3-month intervals and 36.4% of participants used at least one type of CAHC over the 12-month period. Seventy-two percent of parents who used CAHC for their children felt that it was at least somewhat beneficial. Predictors of continued use of CAHC included previous use of CAHC by parents for their own health problems and lower perceived helpfulness of prescribed medications. Neither children's demographic and socioeconomic characteristics nor disease status were associated with CAHC use. CONCLUSIONS: CAHC use in children with JIA is common and considered to be moderately beneficial by most parents who used it. Lower parents' perceived helpfulness of medications and previous use of CAHC are associated with a longer use of CAHC by their child. These facts should be taken into account by health professionals involved in the care of these children.

Factors associated with the use of complementary and alternative medicine in juvenile idiopathic arthritis.

OBJECTIVE: To describe the frequency of complementary and alternative medicine (CAM) use in patients with juvenile idiopathic arthritis (JIA) and to explore whether CAM was associated with patient-specific characteristics, parent-specific characteristics, and medical management factors. METHODS: Parents of children with JIA completed questionnaires that addressed the use of CAM, adherence and perceived problems, parental distress, and coping with childhood illness. Clinical variables were abstracted from the patients' medical files. RESULTS: One hundred-eighteen children with JIA, mean +/- SD age of 10.4 +/- 3.9 years and mean +/- SD disease duration of 4.5 +/- 3.5 years, participated in the study. Ever use of CAM was 33.9% and was higher in patients whose parents used CAM (odds ratio [OR] 5.1, 95% confidence interval [95% CI] 1.4-19.5) and among those who considered themselves as "Canadian" as opposed to belonging to a specific ethnic group (OR 10. 7, 95% CI 1.2-99.8). Adherence to conventional treatment was high for both users and nonusers of CAM. CONCLUSION: Use of CAM is common among patients with JIA. CAM use is not related to any decrease in adherence to conventional medical treatment.
