研究概览

简要总结

This is a healthcare quality improvement study focused on increasing the utilization of arterial grafts in isolated coronary artery bypass grafting (CABG). Evidence indicates that arterial grafts, compared with venous grafts, provide superior long-term patency, which are recommended to use by the clinical practice guidelines.

In hospitals where the use of the internal mammary artery as a graft is relatively low(<90%) among CABG patients, multiple interventions will be implemented to improve its adoption rate.

In hospitals where internal mammary artery graft utilization is already high(≥90%), various interventions will be introduced to promote the use of multiple arterial grafts (defined as the use of two or more arterial conduits).

The study targets healthcare professionals as the primary subjects of intervention, with no direct interventions applied to patients during the study period. Changes in the internal mammary artery graft utilization rate and the multiple arterial graft utilization rate before and after the intervention will serve as the primary endpoints for evaluating intervention effectiveness in the two types of hospitals, respectively.

研究组 & 干预措施

Improving the utilization rate of arterial grafts for coronary artery bypass grafting

Other

In this stepped-wedge cluster randomized trial (SW-CRT) with a self-controlled design, hospitals were categorized into two groups according to their internal mammary artery graft usage rates, thereby forming two SW-CRT. Healthcare professionals at these hospitals will receive tailored interventions. The effectiveness of each intervention is assessed by comparing the usage rates before and after implementation within each SW-CRT.
