Abstract
BACKGROUND: The All New Zealand Acute Coronary Syndrome Quality Improvement (ANZACS-QI) registry was designed to collect data on all coronary angiograms and percutaneous coronary interventions (PCI) in New Zealand, and all acute coronary syndromes (ACS) associated with these procedures. This study compares the completeness of capture in ANZACS-QI of coronary procedures and ACS admissions with those recorded in the National Hospitalisation Dataset and evaluates data quality by assessing agreement in ACS diagnoses and coronary procedures between datasets. METHODS: The national dataset, which included all New Zealand public hospital admissions in 2015 (n=962,700 episodes), was anonymously linked with the ANZACS-QI CathPCI (n=14,649 coronary angiogram episodes) and ACS cohorts (n=8,141 episodes) for 2015. Total numbers of coronary angiogram, PCI and ACS admissions were used as denominators and calculated by combining unique episodes from both data sources. RESULTS: Of all coronary angiogram episodes (n=15,377) and all PCI episodes (n=5,711), 92% were captured in both datasets, 5% in the national dataset only and 3% in ANZACS-QI only. Overall, 95% of coronary angiogram and PCI episodes were captured in ANZACS-QI. Of ACS episodes with associated coronary angiography (n=8,237), 85% were captured. Overall, 54% of all ACS episodes (n=15,167) were captured, including 71% in <70-year-olds. Seventy-five percent of all ST-elevation myocardial infarctions (STEMI) were captured. Ninety percent of ACS diagnoses in ANZACS-QI had a matching diagnosis in the national dataset. There was excellent agreement in recorded gender, date of birth and ethnicity (>99%). Sub-type of ACS was also highly concordant for STEMI and non-STEMI diagnoses (92% and 89% agreement, respectively). CONCLUSIONS: Consistent with its aim, the ANZACS-QI registry captured almost all New Zealand public hospital coronary angiography and PCI procedures including those associated with an ACS diagnosis. The high level of agreement between the registry and national dataset supports the use of both datasets for ongoing quality improvement reporting and research.
