Purpose:
The primary objective of the present pilot study was to investigate the feasibility and acceptability of the newly developed self-care system using personal digital assistance in patients with type 2 diabetes. The secondary objective was to investigate changes in daily calorie intake, body weight, and hemoglobin A1c after using the system for 6 months.
Method:
The participants were nine outpatients with type 2 diabetes, aged 34-72 and living in Tokyo or surrounding prefectures. They were instructed to use the electronic food diary and to review the graphs of the total energy intake to control food intake under their own target value for 6 months. After they completed the study, the feasibility indicated by adherence rate for food recording and acceptability of the system rated with 6-point Likert scale from 1 (worst) to 6 (best) by the participants were investigated.
Results:
Seven participants out of nine completed the study protocol. The median adherence rate for food recording was 80.6 %. Regarding the acceptability, six patients rated 6 for desire to use the system while one rated 5. In addition, regarding improvement in self-care for diabetes, the median score was 5. Daily calorie intake, body weight, and HbA1c, however, did not change significantly over the 6-month period.
Conclusion:
The newly developed self-care system might be feasible and acceptable in diabetes patients, which could be applied as an ecological momentary intervention tool, although there was some room to refine it to raise adherence.
