Multimedia Platform-based Home Care Management for Elderly Patients with Diabetes

Summary

This retrospective cohort study shows that a multimedia platform-based home care model significantly improves glycemic and lipid control, is associated with a lower incidence of cardiovascular complications and reduced frailty, and enhances self-management ability and quality of life in older adults with type 2 diabetes.

Abstract

With the acceleration of population aging, poor blood glucose control and elevated cardiovascular complication risk among older adults with diabetes mellitus (DM) have emerged as significant public health challenges. This study conducted a retrospective, nonrandomized cohort analysis to compare clinical outcomes between two groups of older adults with type 2 diabetes mellitus (T2DM) stratified by treatment period and to investigate the association between a multimedia platform-based home care model and glycemic control, cardiovascular outcomes, and other patient-related outcomes.

A total of 167 older adults with DM were included (82 in the observation group and 85 in the control group). The control group received routine outpatient follow-up between January and August 2024, while the observation group received a 6-month comprehensive intervention via a hospital-developed WeChat mini-program after August 2024. After the 6-month intervention period, significant between-group differences in glycemic and lipid control were observed, with the observation group showing greater improvements from baseline (P < 0.05). A lower incidence of cardiovascular complications during the follow-up period was also observed in the observation group (P < 0.05). Additionally, the proportion of frailty in the observation group decreased from 45.12% to 20.73% after the intervention, and improvements in self-management capability and quality of life (assessed at 6 months post-intervention) were observed in this group.

These observed between-group differences may be partially explained by the behavioral reinforcement, personalized intervention strategies, and multi-risk factor management integrated into the multimedia platform model. Despite limitations including a single-center design and nonrandomized grouping, this model shows preliminary promise for optimizing home-based chronic disease management for older adults with diabetes. Further large-scale, randomized controlled studies are needed to validate these findings and explore the integration of intelligent devices to expand their clinical utility.

Introduction

With the acceleration of global population aging, diabetes mellitus (DM) in the elderly has become one of the major chronic diseases threatening public health¹. Statistics indicate that the prevalence of DM among individuals aged 60 and above reaches as high as 30%, often accompanied by cardiovascular complications (e.g., hypertension, coronary heart disease), significantly increasing disability and mortality rates^2,3. Effective blood glucose management is central to delaying the progression of complications. However, traditional outpatient follow-up models struggle to meet the long-ter....

Protocol

Study participants
Elderly patients with DM who visited the Department of Medical Affairs of Tian Shui Wulin Street Community Health Service Center, Hangzhou, from January 2024 to February 2025 were enrolled in the study, totaling 167 cases (82 in the observation group and 85 in the control group). Inclusion criteria: Age ≥ 60 years; meeting the diagnostic criteria for T2DM¹¹; presenting with at least one cardiovascular risk factor (hypertension, dyslipidemia, obesity, or family history of premature cardiovascular disease); being conscious, with basic communication skills, and able to operate multimedia platforms in....

Results

Multimedia platform usage
The following data reflect adherence to the multimedia platform intervention in the observation group and are implementation indicators rather than clinical outcome measures. Statistical analysis revealed that the frequency of platform logins in the observation group was (21.50±5.63) times per month, with both blood glucose upload rate (89.67%) and video follow-up participation rate (92.58%) reaching approximately 90%, confirming effective utilization of the platform by pati.......

Discussion

The results of this retrospective cohort study showed that elderly patients with type 2 diabetes who received multimedia platform-based home care had significantly better glycemic and lipid control, a lower incidence of cardiovascular events during the 6-month observation period, and improved frailty status, compared with those who received routine outpatient follow-up. This suggests that the model may have potential integrated benefits across multiple dimensions of health outcomes.
