Background: A systematic evaluation of quality of care for patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) as well as the hospital-level variations in quality of care is lacking in China. Methods: The study was based on Improving Care for Cardiovascular Disease in China (CCC) -ACS project, an ongoing collaborative registry and quality improvement project of American Heart Association (AHA) and Chinese Society of Cardiology (CSC). A total of 26186 patients from 124 hospitals reported to the registry between November 2014 and March 2018 were included. Application of 9 class I guidelines recommended care processes with a level of evidence A were evaluated among eligible patients. The overall quality of care for NSTE-ACS patients was evaluated by calculating the proportion of patients receiving defect-free evidence-based care. The variations in quality of care across hospitals were examined by aggregating the data to the hospital level. Results: Information on eligibility for all the care processes was available for 25956 patients. Overall, only 1789 patients (6.9%) received evidence-based defect-free care. The proportion varied across hospitals, ranging from 0 to 32.4%. The proportion of patients receiving each care process was 91.9% for cardiac troponin measurement, 55.2% for risk stratification, 88.8% for dual antiplatelet therapy (DAPT) within 24 hours, 17.9% for percutaneous coronary intervention (PCI) within recommended times, 83.6%, 57.4%, 66.3% and 92.3% for DAPT, ACEI/ARB, β blocker and statin at discharge, respectively. Different degree of variability existed across hospitals for each care process. Proportion of patients receiving cardiac troponin measurement, DAPT within 24 hours, and statin at discharge exhibited low degree of variance across hospitals. Great variability existed in proportion of patients receiving risk stratification (0 to 100%), PCI within recommended times (0 to 72.7%), ACEI/ARB at discharge (13.2% to 84.8%), β blocker at discharge (9.8% to 93.3%), and smoking cessation counseling (0 to 98.1%). Conclusions: Great care gaps existed in the management of NSTE-ACS patients between guideline recommendations and clinical practice in China. There are substantial differences in the quality of care for NSTE-ACS patients across hospitals. [ABSTRACT FROM AUTHOR]

Introduction: Despite advance in the treatment of ST-elevation myocardial infarction (STEMI), how the current clinical practice varies across hospitals in China is less known. This study evaluated the variation in hospital management of STEMI from data collected in the Improving Care for Cardiovascular Disease in China (CCC) Project. Methods: As a nation-wide quality improvement registry in China, the CCC project was established among 150 tertiary hospitals in collaboration of American Heart Association (AHA) and Chinese Society of Cardiology. Clinical information of AHA/ACC guidelines recommended therapies were collected from November 2014 to March 2018. Average level and variation in hospital management of STEMI were evaluated. Results: A total of 45240 patients with STEMI across China were included in this study. The mean age of the participants was 61.7±12.6 years and 78.2% of them were men. The median of hospital stays was 10 days, with substantial variation across the hospitals (inter-quartile range, 7-13 days). The performances for quality measure were low for β-blocker at discharge (67.3%, 12.5%-96.9%), ACEI/ARB at discharge (55.9%, range across hospitals: 8.3%-94.9%) and smoking cessation advice (34.6%, 0%-97.2%) in eligible patients, with high variability across hospitals. High-performing measures included P2Y12 inhibitor at discharge (96.5%, 38.1%-100%), aspirin at arrival (96.3%, 76.1%-100%) and discharge (93.7%, 35.2%-100%), statins at discharge (92.4%, 36.9%-100%) in eligible patients. After excluding transferred patients, reperfusion for STEMI was performed in 61.1% (6.7%-98.1%) of the 21 908 patients admitted directly with STEMI. Primary PCI and fibrinolysis accounted for 97% and 3% of these reperfusions, respectively. Conclusions: The quality of care for patients hospitalized with STEMI is not satisfactory in China, even among tertiary hospitals. Large disparities exist across hospitals and continuous quality improvement projects are warranted. [ABSTRACT FROM AUTHOR]
