Abstract
BACKGROUND: The All New Zealand Acute Coronary Syndrome Quality Improvement (ANZACS-QI) program comprises a clinical quality registry of acute coronary syndrome patients admitted to hospitals across New Zealand. Its primary purpose is to improve quality of care by promoting evidence- and guidelines-based practice, and benchmarking against performance targets. Few studies have examined the cost-effectiveness attributed to clinical quality registries. We aimed to evaluate the clinical and cost impacts of the ANZACS-QI program in New Zealand from both a societal and health care system perspective. METHODS: Using decision analytic Markov models, we estimated the effectiveness and costs of the ANZACS-QI program in each year over 4 years (2013-2016), against a hypothetical scenario where the registry did not exist. We assumed that the ANZACS-QI contributed to 15% of the temporal changes to patient mortality and hospital readmissions for myocardial infarction observed in the study period. Marginal costs of the registry and years of life saved were estimated. RESULTS: Over a one-year period, the return on investment (ROI) ratio for the ANZACS-QI program was 1.53; thus, every dollar spent on the program resulted in a return of NZD $1.53. (All dollars are in 2017 New Zealand dollars [NZD] unless otherwise stated). The estimated incremental cost-effectiveness ratio (ICER) was $113,327 per year of life saved (YoLS). Extending the time horizon to 5 years, reduced the ICER to $19,684 per YoLS. CONCLUSIONS: The ANZACS-QI program represents a sound investment for New Zealand. Even based on highly conservative assumptions, the program is cost saving for society, at a ROI ratio of about 1.5 each year.
