Outline of Final Research Achievements

Objectives: This study's primary objective was to verify whether an eHealth-based self-management program can reduce the severity of IBS symptoms.
Methods: This study was an open-label, simple randomized controlled trial that compared an intervention group (n = 21) participating in an eHealth self-management program, with a treatment-as-usual group (n = 19). The eHealth program was organized into five chapters based on the content of a self-help guidebook whose efficacy has been previously confirmed. The eHealth group received unlimited access to the self-management program for eight weeks. The main outcome, participants’ severity of IBS symptoms, was assessed using the IBS-severity index (IBS-SI) at baseline and eight weeks.
Results: There was a significant difference in the net change in the IBS-SI score between the eHealth and treatment-as-usual groups (-50.1; 95% CI, -87.6 to -12.6; p = 0.010).

Academic Significance and Societal Importance of the Research Achievements

本研究では、慢性疾患であるIBSを対象としたセルフマネジメント方法の1つであるeHealthが症状軽減に寄与するかどうかを科学的に検証した。その結果、eHealthがIBS症状軽減に寄与していることを示したとともに、QOLの向上、さらに腸内細菌の改善効果があることが分かった。慢性疾患を対象として得られたこれらの多面的な結果は、多くの慢性疾患に対してアクセシビリティの高いeHealthを用いたセルフマネジメントが高い効果を有することを示す結果であった。この点が社会的意義のある点であった。
