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).
