Reporting of determinants of health inequities and participant characteristics in randomized controlled trials of juvenile idiopathic arthritis in Canada: a scoping review

Abstract

Abstract Background Juvenile Idiopathic Arthritis (JIA) is the most common form of childhood inflammatory arthritis. The disease burden of JIA is substantial as patients require specialized medical practitioners for diagnosis and chronic treatments that are both costly and time intensive. Discrepancies in access to care due to health inequities such as socioeconomic status or geographic location may lead to vastly different health outcomes. As research informs advances in care, is important to consider inclusion and diversity in JIA research. Methods We reviewed and synthesized randomized controlled trials for juvenile idiopathic arthritis, the most common type of arthritis among children and adolescents, in Canada with the aim of characterizing participants and identifying how determinants of health inequities are reported. To do so, we searched Medline (1990 to July 2022), Embase (1990 to July 2022), and CENTRAL (inception to July 2022) for articles meeting all of the following criteria: Canadian randomized controlled trials evaluating pharmacological or non-pharmacological interventions on juvenile idiopathic arthritis populations. Data extraction was guided by the Campbell and Cochrane Equity Methods Group’s PROGRESS-Plus framework on determinants that lead to health inequities (e.g., Place of residence; Race; Occupation; Gender/Sex; Religion; Education; Socioeconomic status; and Social capital). Results Of 4,074 unique records, 5 were deemed eligible for inclusion. From these determinants of health inequities, Gender/Sex and Age were the only that were reported in all studies with most participants being female and 12.6 years old on average. In addition, Race, Socioeconomic status, Education and Features of relationships were each reported once in three different studies. Lastly, Place of residence, Occupation, Religion, Social Capital and Time-dependent relationships were not reported at all. Conclusions This scoping review suggests limited reporting on determinants of health inequities in randomized controlled trials for JIA in Canada and a need for a reporting framework that reflects typical characteristics of juvenile patient populations.
