Digital health program improves quality of life in rheumatoid arthritis: a retrospective analysis of real-world data.

Abstract

Sidekick Health launched a 16-week digital support programme for people with rheumatoid arthritis in 2021. The objective of this retrospective analysis was to understand whether quality of life (QoL; sleep quality, energy and stress levels) improved for users engaged with the programme in a real-world setting. This analysis included 635 users who engaged with the programme after the first week, out of 1541 who enrolled. Users self-reported QoL up to four times per week on their phones. Survival bias was investigated by comparing pre-post QoL scores of the full analysis set (all users) and the complete case set (programme completers). Users were divided into highly-engaged and less-engaged groups based on the weekly average number of in-app activities by iterative K-means clustering. Mixed models for repeated measures were used to estimate changes in QoL for highly-versus less-engaged groups. Both the full analysis set and the complete case set had significant pre-post improvements in energy and stress; this suggested that survival bias did not have a substantial effect on these real-world data. Both the highly- and less-engaged groups experienced significant longitudinal improvements in all QoL outcomes. Highly-engaged users achieved better scores in energy, stress, and sleep than less-engaged users. Moreover, a significant time-group interaction for sleep showed that highly-engaged users not only had better sleep scores, but also experienced larger improvements over time than less-engaged users. These findings demonstrate that a 16-week digital support programme improves self-reported QoL measures, supporting the 2021 EULAR recommendations to incorporate digital healthcare into routine practice. Noteworthy is the study's relevance in the context of the increasing importance of patient empowerment in managing chronic diseases.
