Sustained A1c Reduction Facilitated by Minimally Time-Consuming,Ongoing Outcome Assessments and Guided Interventions in a Rural Diabetes Education Program

Abstract

Purpose

To evaluate the effect and sustainability of A1c reduction in a rural diabetes education program that integrates minimally time-consuming, ongoing outcome assessments and interventions guided by these assessments.

Design

Retrospective pre-post studies in monthly cohorts.

Setting

A clinic in rural Wisconsin.

Subjects

Individuals with type 1 or type 2 diabetes who completed initial program visits between October 2023 and March 2024 (n = 86; monthly cohort sizes ranged from 10 to 18).

Intervention

A diabetes education program that incorporates minimally time-consuming, ongoing outcome assessments and guided interventions.

Measures

Baseline A1c values and the most recent A1c values by the end of months 7 and 13.

Analysis

At the practice level, average A1c reductions were calculated for each monthly cohort, and paired t-tests were used to assess statistical significance. At the individual level, A1c values were plotted to guide interventions.

Results

All 6 monthly cohorts showed average A1c reductions between 1.0% and 2.4% at both the 7- and 13-month time points. Most reductions were statistically significant. Interventions guided by individual-level assessments appeared to support improved outcomes.

Conclusion

This rural diabetes education program demonstrated sustained A1c improvement using practical, minimally resource-intensive outcome assessments and guided interventions. While the absence of a control group limits causal inference, this approach may offer a feasible model for chronic disease management in resource-limited settings.
