Health Impact of a Mobile-Delivered Diabetes Intervention to Control Blood Pressure in Older Adults

Abstract

Introduction

Patient education is an effective modality to reinforce self-care practices for chronic disease management. The purpose of this study was twofold: (1) to assess the health impact of a phone-delivered diabetes intervention and (2) to identify predictors of telehealth message use among adults aged 18–65 years with diabetes in a primary care setting using the Technology Acceptance Model theoretical framework.

Methods

A pretest–posttest experimental study design was employed. Participants were randomized to receive 7 weeks of telehealth self-care messages or to the routine care group. Outcome measures included (1) telehealth use among patients who received weekly telehealth messages, (2) self-care behavior management derived from the Behavior Score Instrument, and (3) clinical outcomes measures.

Results

The study team enrolled 150 patients, and of these, 138 (aged 18–65 years) completed the study. Participants aged 53±9.6 (mean±SD) years were mainly females (n=93; 76%), and the majority received government-sponsored health insurance (n=75; 54%). Age was a strong predictor of telehealth use (p<0.001). Among patients who received telehealth messages, systolic and diastolic blood pressure measures (140/78 mmHg vs 134/74 mmHg) were statistically significant at follow-up (p=0.001 and p=0.007, respectively).

Conclusions

Digital support tools can play a valuable role in supporting lifestyle modification changes and reinforcing good diabetes self-care practices in older adults. Providing accessible tools and resources empowers adults to take an active role in their own health.
