Insights
Saudi Arabia established the Saudi CABG Audit and Registry (SCAR) for standardized cardiac surgery outcome surveillance. This national registry aims to improve quality, research, and patient risk stratification for coronary artery bypass grafting (CABG).
Area of Science:
- Cardiovascular Surgery
- Health Services Research
- Clinical Quality Improvement
Background:
- Coronary artery disease (CAD) is a major health concern in Saudi Arabia.
- Lack of standardized surveillance for coronary artery bypass grafting (CABG) outcomes.
- Establishment of the Saudi CABG Audit and Registry (SCAR) to address this gap.
Purpose of the Study:
- To create the first national registry for CABG outcomes in Saudi Arabia.
- To enable standardized surveillance and quality assessment of CABG procedures.
- To facilitate multicenter research and development of local risk prediction models.
Main Methods:
- Prospective, multicenter clinical quality registry.
- Enrollment of consecutive patients undergoing isolated or combined CABG.
- Collection of over 100 variables including demographics, comorbidities, operative details, and longitudinal follow-up to one year.
- Structured follow-up at 30 days, 3 months, 6 months, and one year.
Main Results:
- The SCAR registry captures comprehensive data for CABG patients.
- A four-tier analytical framework is employed for data analysis, including risk-adjusted benchmarking.
- Pilot phase involves 100-150 procedures across four centers.
Conclusions:
- SCAR is the inaugural national CABG registry in Saudi Arabia.
- The registry will support quality improvement initiatives through risk-adjusted benchmarking.
- It is expected to enhance healthcare planning and develop locally relevant risk stratification tools for CABG.
Abstract:
Background: Coronary artery disease is a leading cause of morbidity and mortality in Saudi Arabia. No national mechanism exists for standardized CABG outcome surveillance. The Saudi CABG Audit and Registry (SCAR) was established to address this gap. Methods: SCAR is a prospective multicenter clinical quality registry enrolling consecutive patients undergoing isolated or combined CABG across Saudi Arabia. The dataset captures more than 100 variables spanning demographics, comorbidities, operative details, in-hospital outcomes, and longitudinal follow-up to one year. Primary outcomes include in-hospital mortality, 30-day major adverse cardiac and cerebrovascular events (MACCE), deep sternal wound infection, and unplanned reoperation. Results: The registry incorporates structured follow-up at 30 days, 3 months, 6 months, and one year, governed through three national committees overseeing data quality and dissemination. A four-tier analytical framework progresses from descriptive analyses through risk-adjusted benchmarking, validation of international risk models, and future development of a locally derived risk prediction model. Implementation commences with a pilot phase enrolling 100-150 consecutive procedures across four centers over three months. Conclusions: SCAR represents the first dedicated national CABG registry in Saudi Arabia. Through risk-adjusted benchmarking and structured feedback, the registry may support quality improvement, multicenter research, healthcare planning, and development of locally relevant risk stratification tools.
