Abstract 383: Characteristics and Outcomes of Patients Undergoing Cardiac Catheterisation Procedures in US versus Australian Hospitals
Introduction: CathPCI Registry® is well established in providing assessment and benchmarking of patients undergoing catheterization and/or percutaneous coronary intervention (PCI). In 2011, the Coronary Angiogram Database of South Australia (CADOSA) was established as a quality assurance tool for cardiac interventions performed at all tertiary facilities in South Australia. CADOSA is compatible with the CathPCI Registry® with the use of common data elements and definitions, thereby allowing international comparisons.
Objective: To compare Australian and United States (US) cardiac catheterization patients and practices using the unique infrastructure of CADOSA and CathPCI Registry®.
Methods: Data collected for adult patients undergoing catheterization and/or PCI in 2012 was collated. Patients with cardiomyopathy and no symptoms or valvular heart disease were excluded.
Results: In 2012, there were 1,415,326 cases in CathPCI Registry®, of which 46% were PCI. In contrast, CADOSA included 4,806 cases of which 29% were PCI. Prior revascularization was more frequent in CathPCI Registry® (prior PCI 32%, prior CABG 16%) compared to CADOSA (prior PCI 17%, prior CABG 8%). Acute coronary syndrome was the procedure indication for 63% of CathPCI Registry® cases and 55% of CADOSA, and 82% of CADOSA procedures had radial access sites compared to 45% in CathPCI Registry®. Table 1 summaries the PCI cases.
Conclusions: In Australia, coronary angiography is frequently performed using radial approach, and PCI cases are often emergency reflecting the inclusion of tertiary referral centres. Elective PCI in the US is commonly preceded by SPECT. The potent antiplatelet inhibitors are also frequently administered during PCI. Whether the practice differences are related to significant differences in post procedure outcomes is unknown. This international comparison creates a broad perspective for cardiac health outcomes research and justifies further collaborative analyses.
