Effects of digital self-care intervention for Korean older adults with type 2 diabetes: A randomized controlled trial over 12 weeks

This study developed and assessed the impact of a digitally enabled self-care intervention program tailored for older adults with type 2 diabetes led by nursing professionals. A randomized controlled trial of a 12-week digital self-care intervention was conducted with 105 older Korean adults with type 2 diabetes. The intervention involved self-recording in the DiaNote application, newly developed for the study and a phone visit. Participants were randomly allocated to DiaNote or traditional logbook groups. Outcomes were collected at baseline and again after 12 weeks. Generalized estimating equations indicated that HbA1c level changes over time significantly in DiaNote group. Diabetes self-care activities and quality of life changed over time in both groups. Self-efficacy did not significantly differ between groups or over time. The digital self-care intervention was beneficial for blood sugar control, being equivalent to using a traditional diabetes logbook for quality of life and diabetic self-care.
