Digital health tools in juvenile idiopathic arthritis: a systematic literature review.

backgroundNowadays, digital health technologies, including mobile apps, wearable technologies, social media, websites, electronic medical records, and artificial intelligence, are impacting disease management and outcomes. We aimed to analyse the characteristics and use of digital health tools in juvenile idiopathic arthritis (JIA).

methodsWe conducted a systematic review (SR) to identify articles examining the characteristics, use, and outcomes (feasibility, usability, and effectiveness) of digital health tools in JIA patients. A sensitive search strategy was performed in Medline, Embase, and Cochrane databases until December 2022 (later updated to March 2024). Two reviewers independently selected the studies and collected the data, including study quality. A descriptive analysis was performed.

resultsA total of 21 studies were included, one SR, six randomised controlled trials, four observational studies, four validation studies, one discovery and verification study, and five qualitative studies. Study quality was generally moderate. Most studies focused on patients with JIA (especially young people), but also on parents and health care professionals. Different digital health technologies were investigated, like websites, mobile apps, wearables, and telemedicine. The main objectives of the tools were self-management, symptom and quality of life monitoring, physical activity tracking, disease knowledge improvement, and medication monitoring. Different themes and contents were usually included in the same digital health tool, such as psychological health, lifestyle, intimacy, or shared decision-making. Tool development and validation processes were poorly or not at all described, and data regarding regulatory compliance, security, or privacy were scarce.

conclusionsThere is significant variability in the type, characteristics, objectives, and contents of digital health tools for JIA. They still show limitations and gaps, thus highlighting the need for better critical assessment and reporting.
