Application of Quality Control Circles in Remote ECG Network Management to Standardize ECG Operational Procedures

Objective: To examine the effectiveness of Quality Control Circles (QCC)in remote Electrocardiography (ECG) network management, with a particular focus on evaluating their impact on improving operational standardization. Methods: Electrocardiogram data from Qingdao Central Hospital was selected as the research subject. Among them, 402 cases collected from January to April 2024 were before the implementation of QCC activities, and 356 cases collected from January to April 2025 were after the implementation of QCC activities. The irregularity rates of the electrocardiogram data between the two groups were compared. By establishing QCC teams, issues related to non-standardized operations at the 12-lead ECG acquisition endpoints were analyzed, and targeted improvement measures were developed. Results: Following QCC implementation, the non-compliant operation rate at 12-lead ECG collection endpoints within the network system significantly decreased, from 17.66% to 6.17% (P
