Enhancing the proactive risk management function of the Rapid Response System(RRS)can effectively im-prove its critical care capabilities.Panyu Hospital of Traditional Chinese Medicine of Guangzhou(Panyu Hospital Guangzhou University of Chinese Medicine)has established the ABCDE-RRS system for critical care,which stands for Able(enhanced post capacity),Broad(diverse quality control),Comprehensive(full participation),Deep(continuous talent cultivation and system optimization),and Early(proactive risk management).This system ensures that the number of critically ill hospitalized patients continues to grow(an increase of 8.99％in the first three quarters of 2024 compared to the same period last year,P＜0.05)while effectively reducing the all-cause mortality rate of hospitalized patients(a decrease of 0.05％in the first three quarters of 2024 compared to the same period last year,P＜0.05).It also enhances the safety culture awareness among all staff(an in-crease of 39.05％after implementation,P＜0.05)and improves patient satisfaction with the hospital(the comprehensive patient evaluation ranking of public hospitals in Guangzhou improved from 17th to 12th place).By establishing an effective operational model for ABCDE-RRS and a tiered talent training model for RRS,this provides a replicable template for the construction of RRS in primary hospitals.

Objective     To evaluate the clinical efficacy of coronary artery bypass grafting in the treatment of coronary artery disease patients aged over 70 years. Methods     A total of 160 patients with coronary atherosclerotic heart disease underwent off-pump coronary artery bypass grafting from January 2013 to December 2017. There were 94 males and 66 females at age of 70–85 (76.67±2.33) years. Operations were performed by using sternal median incision with the assistance of local myocardial surface fixator and shunt plug, and the saphenous vein and internal mammary arterywere used as grafted vessels. Results     All the patients were received successful off-pump coronary artery bypass grafting without death, and the cardiac function improved significantly. There were 62 patients with the internal mammary artery bridge and 98 patients with the whole vein bridge. All the patients were followed-up for 1 to 4 years. All the patients had obvious relief of angina pectoris. Conclusion     Off-pump coronary artery bypass grafting for the treatment of elderly patients with coronary heart disease is an effective and safe operation, especially for patients with renal insufficiency, cerebrovascular disease, respiratory disease and severe left ventricular dysfunction.
