The rapid growth of digital technology is revolutionizing the management of type 2 diabetes mellitus (T2DM). This study investigates the effectiveness and safety of various digital interventions aimed at reducing glycated hemoglobin A1c (HbA1c) levels, a crucial marker in diabetes management. The study underscores the importance of achieving glycemic targets to prevent both acute and long-term complications associated with diabetes.
Methodology and Study Design
A systematic literature review (SLR) was conducted by searching Embase, MEDLINE, and CENTRAL databases on April 5, 2022. Two independent reviewers performed study selection, data extraction, and quality assessment. The eligibility criteria included randomized controlled trials (RCTs) and comparative observational studies focusing on interventions combining human elements (e.g., coaching) and digital components (e.g., glucose meters) for adult T2DM patients. The primary meta-analysis was confined to studies that reported laboratory-measured HbA1c levels.
Findings and Market Access Implications
Out of 28 studies reviewed, a substantial majority (82%) used HbA1c reduction as their primary outcome. Significant results were found in 21 studies. The data revealed that higher coaching intensity in digital interventions correlated with greater success rates. Specifically, high-intensity interventions reported a reduction of -0.45% in HbA1c levels, while medium- and low-intensity interventions achieved -0.29% and -0.28% reductions, respectively. This highlights the critical role of personalized coaching in the efficacy of digital health solutions. These findings could enhance market access by demonstrating that such interventions not only meet clinical needs but also provide substantial health benefits.
However, the effectiveness was less clear in RCTs exclusively using comparative improvement of HbA1c levels, with only half showing statistically significant results. This gap underscores the need for further targeted research to solidify the position of digital interventions in clinical practice and market access strategies.
Key Inferences
- High-intensity digital interventions involving personalized coaching yield better HbA1c reductions, enhancing their market potential.
- Only 52% of RCTs reported significant results, indicating a need for more rigorous evidence to support market adoption.
- Meta-regression aligns with SLR results, reinforcing the credibility of digital interventions in reducing HbA1c levels.
The results of this study affirm that digital interventions are a feasible and effective approach to managing T2DM, particularly when combined with personalized coaching. These findings are instrumental for stakeholders aiming to enhance market access and adoption of digital health technologies.

ABSTRACT
BACKGROUND: The proliferation of digital technology has the potential to transform diabetes management. One of the critical aspects of modern diabetes management remains the achievement of glycemic targets to avoid acute and long-term complications.
OBJECTIVE: This study aims to describe the landscape of evidence pertaining to the relative effectiveness or efficacy and safety of various digital interventions for the self-management of type 2 diabetes mellitus (T2DM), with a primary focus on reducing glycated hemoglobin A1c (HbA1c) levels.
METHODS: A systematic literature review (SLR) was conducted by searching Embase, MEDLINE, and CENTRAL on April 5, 2022. Study selection, data extraction, and quality assessment were performed by 2 independent reviewers. Eligibility criteria for the SLR included randomized controlled trials (RCTs) and comparative observational studies evaluating interventions containing both human (eg, coaching) and digital components (eg, glucose meter) in adult patients with T2DM. The primary meta-analysis was restricted to studies that reported laboratory-measured HbA1c. In secondary analyses, meta-regression was performed with the intensity of coaching in the digital intervention as a categorical covariate.
RESULTS: In total, 28 studies were included in this analysis. Most studies (23/28, 82%) used the reduction of HbA1c levels as the primary end point, either directly or as a part of a multicomponent outcome. In total, 21 studies reported statistically significant results with this primary end point. When stratified into 3 intervention categories by the intensity of the intervention supporting the digital health technology (analyzing all 28 studies), the success rate appeared to be proportional to the coaching intensity (ie, higher-intensity studies reported higher success rates). When the analysis was restricted to RCTs using the comparative improvement of HbA1c levels, the effectiveness of the interventions was less clear. Only half (12/23, 52%) of the included RCTs reported statistically significant results. The meta-analyses were broadly aligned with the results of the SLR. The primary analysis estimated a greater reduction in HbA1c associated with digital interventions compared with usual care (-0.31%, 95% CI -0.45% to -0.16%; P<.001). Meta-regression estimated reductions of -0.45% (95% CI -0.81% to -0.09%; P=.02), -0.29% (95% CI -0.48% to -0.11%; P=.003), and -0.28% (95% CI -0.65% to 0.09%; P=.20) associated with high-, medium-, and low-intensity interventions, respectively.
CONCLUSIONS: These findings suggest that reducing HbA1c levels in individuals with T2DM with the help of digital interventions is feasible, effective, and acceptable. One common feature of effective digital health interventions was the availability of timely and responsive personalized coaching by a dedicated health care professional.
