About this trial
The Saudi CABG Audit and Registry (SCAR) is a prospective, multicenter national clinical quality registry designed to systematically collect perioperative and long-term outcome data for all patients undergoing coronary artery bypass grafting (CABG) in Saudi Arabia. The registry will begin with a pilot phase in selected tertiary cardiac centers and will progressively expand to national coverage. SCAR captures detailed information on patient demographics, cardiac status, operative techniques, postoperative outcomes, and 1-year follow-up, including patient-reported quality-of-life measures (EQ-5D and SF-36). The aim is to establish a standardized national platform for benchmarking, quality improvement, and real-world evidence generation to support clinical decision-making and health policy development in cardiac surgery. Data are collected prospectively through secure electronic systems, anonymized before central storage, and analyzed using standardized definitions aligned with international registries such as STS and E-CABG.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Adult patients aged 18 years or older
Undergoing isolated CABG
Undergoing CABG with concomitant procedures (e.g., valve repair or replacement)
Undergoing on-pump, off-pump, minimally invasive, or robotic CABG
Disqualifiers
Redo CABG when the primary operative record is not available
Patients younger than 18 years
Trial population
Adult patients (≥18 years) undergoing coronary artery bypass grafting (CABG) at participating cardiac surgery centers in Saudi Arabia. The population includes individuals receiving isolated CABG or CABG with concomitant procedures, performed electively, urgently, or emergently, using on-pump, off-pump, minimally invasive, or robotic approaches.

Prospective Clinical Data Collection
Other interventionThe intervention consists of systematic, prospective collection of standardized clinical, operative, and follow-up data for all adult patients undergoing coronary artery bypass grafting (CABG) at participating centers. Data are recorded across predefined time points, including preoperative assessment, intraoperative details, postoperative in-hospital outcomes, and follow-up at 30 days, 3 months, 6 months, and 1 year. Variables include demographics, comorbidities, cardiac status, operative technique, complications, readmissions, mortality, and patient-reported quality-of-life measures (EQ-5D and SF-36). No treatments are assigned. The registry functions solely as an observational platform for quality improvement, benchmarking, and long-term outcome monitoring.

Trial outcomes
Primary outcomes
1
Incidence of In-hospital mortality
In-hospital all-cause mortality following coronary artery bypass grafting (CABG), recorded from the time of surgery until discharge. Mortality will be determined using standardized definitions aligned with major cardiac surgery registries such as STS and E-CABG.
Time frame
From date of surgery through hospital discharge, an average of 7-10 days.2
Incidence of 30-day major adverse cardiac and cerebrovascular events (MACCE)
Composite endpoint including 30-day all-cause mortality, stroke, and myocardial infarction after coronary artery bypass grafting (CABG). Event definitions follow standardized criteria used in major cardiac surgery registries, including STS and E-CABG.
Time frame
30 days post-surgery3
Incidence of Deep sternal wound infection (DSWI)
Incidence of deep sternal wound infection following coronary artery bypass grafting (CABG), defined according to Centers for Disease Control and Prevention (CDC) criteria. Includes infections involving muscle, bone, or mediastinum requiring surgical intervention, antibiotics, or drainage.
Time frame
From surgery until 30 days post-operation4
Unplanned reoperation for bleeding, tamponade, or graft-related technical failure
Incidence of unplanned return to the operating room after coronary artery bypass grafting (CABG) due to postoperative bleeding, cardiac tamponade, or graft-related technical failure. Events follow standardized definitions aligned with international cardiac surgery registries.
Time frame
Perioperative/PeriproceduralSecondary outcomes
1
Intensive care unit (ICU) length of stay
Duration of postoperative stay in the intensive care unit following CABG surgery, measured in hours or days. Includes all ICU readmissions during the index hospitalization.
Time frame
From the date of surgery through initial ICU discharge (average of 3-5 days).2
Total hospital length of stay
Duration of hospitalization from the day of surgery until discharge, measured in days. Includes all in-hospital recovery time after CABG.
Time frame
From the date of surgery through hospital discharge (average of 7-10 days).3
Duration of mechanical ventilation
Total time on postoperative mechanical ventilation following CABG surgery, measured in hours. Includes any episodes of re-intubation requiring ventilatory support.
Time frame
From completion of surgery through extubation, an average of 12-24 hours4
Incidence of 30-day readmission
Incidence of all-cause hospital readmission occurring within 30 days of discharge after CABG surgery.
Time frame
Within 30 days post-dischargeLocations
