A Nurse‐Led Educational Intervention for Patients With Type 1 Diabetes Using Continuous Glucose Monitoring

ABSTRACT

Background

The primary barrier to maximizing the benefits of intermittently scanned continuous glucose monitoring (isCGM) is low scan frequency. Higher daily scan frequency correlates with better glycemic control.

Aim

To evaluate the effect of a nurse-led educational intervention on scan frequency and behavioral change in adults with type 1 diabetes (T1D) showing low scanning frequency.

Methods

In this 12-week quasi-experimental study, adults with T1D using isCGM and low scan frequency participated in a single, individualized, direct education session led by a diabetes nurse educator. The intervention focused on increasing daily scan frequency and supporting patient engagement in self-management.

Results

Thirty-four patients using isCGM participated. Mean daily scan frequency increased from 3.1 to 6.1 scans/day following the intervention. This rise was associated with an 8.0% improvement in TIR. A positive correlation was observed between scan frequency and TIR, with each additional daily scan associated with a 0.51% increase in TIR.

Linking Evidence to Action

A single, targeted educational session can significantly improve isCGM adherence and glycemic control in adults with T1D and low adherence, supporting its value as a practical strategy in routine clinical care.

Trial Registration

The protocol was publicly registered at ClinicalTrials.gov (NCT05570162)
