The Chinese Cardiac Surgery Registry: Design and Data Audit

Abstract

The newly launched CCSR with a national representativeness network and good data quality has the potential to act as an important platform for monitoring and improving cardiac surgical care in mainland China, as well as facilitating research projects, establishing benchmarking standards, and identifying potential areas for quality improvements (ClinicalTrials.gov No. NCT02400125).

Comparing Outcomes of Coronary Artery Bypass Grafting Among Large Teaching and Urban Hospitals in China and the United States

“…The CCSR, which was similar to the Society for Thoracic Surgeons in the United States, was established in 2004 to advance CABG-related outcomes in China. 8 The registry, which aims to evaluate surgical outcomes in patients undergoing cardiac surgery, has a committee comprising cardiac surgeons and researchers from universities and major teaching hospitals in China. In 2013, there were 734 hospitals in China offering cardiac surgery services, 209 of which have an annual volume of >200 patients.…”

“…8 Until now, it has become the largest and the most representative database in cardiovascular surgery all over the country. The registry includes all patients who underwent CABG or valve surgery at each participating hospital.…”

“…In 2012, Agency for Healthcare Research and Quality changed the sampling method for NIS. 8 The new method samples 20% of all discharges from all hospitals. To align the 2007 to 2011 NIS data with 2012 and 2013 NIS data, we first randomly selected 20% discharges from the 2007 to 2011 NIS data and then randomly selected 20% of hospitals from the 2012 and 2013 NIS data and appended these 2 subsamples together.…”

“…Databases including National Inpatient Sample (NIS) in the United States and the Chinese Cardiac Surgery Registry (CCSR) are nationwide multicenter and consecutive registries, which have become the cornerstone of clinical quality assessment and improvement. 7,8 Accordingly, a comparison of CABG outcomes between China and the United States can provide insight about the patients referred for operation and the results being produced in countries with different systems.…”

Effect of Cardiac Surgery-Associated Acute Kidney Injury on Long-Term Outcomes of Chinese Patients: A Historical Cohort Study

“…Fourth, some information of long-term outcomes was obtained by telephone or message and serum SCr levels were not measured in the same hospital. Hence, future multicenter studies with larger sample of Chinese patients are needed to explore the long-term outcomes of CSA-AKI, not only including renal outcomes but also other complications [21]. …”
