Initial Twelve Months Experience and Analysis for 2001–2002 from the Australasian Society of Cardiac and Thoracic Surgeons—Victorian Database Project

Results. Overall, there were 2982 procedures performed in this period of which 2969 had sufficient data to be included in this analysis (99.5%). The majority of procedures 2017 (68%) being undertaken were isolated coronary artery bypass surgery (CABG). The mean age of all subjects undergoing procedures was 65 years (range: 18–91 years) and 70% were male. 64% of all procedures were elective and 6.1% emergency or salvage. Median post-procedure length of hospital stay for all procedures was 6.0 days and intensive care unit (ICU) stay was 23.0 h. Re-operation for haemorrhage occurred in 2.1% of all cases and deep sternal infection in 0.4% of all cases. Crude 30-day operative mortality was 3.6% for all procedures; 2.1% for isolated CABG, 3.6% for valve procedures, 5.2% for valve and CABG and 11.4% for other cardiac surgical procedures. Mortality rates increased from 1.8% for elective procedures to 4.1% for urgent and 24.6% for emergency or salvage operations. In comparison to international figures from the USA and UK, mortality rates following isolated CABG were lower whilst average length of hospital stay post-procedure was higher. Conclusion. The ASCTS database project is now well established and the electronic database and reporting module is in operation in all participating sites. The risk-adjusted isolated operative mortality suggests cardiac surgical performance in Victoria compares well with international standards. As the database develops, local risk-adjustment models for mortality and morbidity for each procedure will be developed to enable appropriate between hospital comparisons.
