Application of digital and intelligent intervention in medication errors of metformin after CTA examination

To explore the effectiveness of digital and intelligent intervention in the medication errors of metformin after CTA examination.

Patients who underwent CTA examinations in a tertiary A general hospital in Jiangsu Province from January to September 2025 were selected as the study subjects. The patients from January to April 2025 who received intervention based on conventional information technology were in a control group, and the patients from June to September 2025 who received digital and intelligent intervention were in an intervention group. The incidence of metformin misadministration, the satisfaction of medical staff, the pass rate of the assessment on medication contraindications for CTA examinations, the participation rate of caregivers, the compliance rate of nurses in distributing oral medications, and the number of oral medication errors were compared between the 2 groups.

After applying digital and intelligent intervention, the incidence of metformin overdose in CTA examination patients decreased from 2.36 to 0.32%. There was a statistically significant difference between the intervention group and the control group (χ² = 85.340, P < 0.001). The satisfaction rate of medical staff was 98.41%, which was higher than 82.22% before the intervention (χ² = 132.405, P < 0.001). The pass rate of medical staff's assessment on CTA examination medication contraindications was 96.60%, which was significantly higher than 76.16% before the intervention (χ² = 126.103, P < 0.001). The participation rate of CTA examination patients' caregivers increased from 46.71 to 96.67% (χ² = 3390.581, P < 0.001). The compliance rate of nurses in distributing oral medications increased from 90.03 to 98.53% (χ² = 40.972, P < 0.001). The number of oral medication errors decreased from 3 cases before the intervention to 1 case after the intervention.

Digital and intelligent intervention can reduce medication errors of metformin after CTA examination for patients. These interventions help decrease the incidence of adverse events, promote the involvement of both patients and caregivers, optimize the healthcare service system, and ensure patient safety.
