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. [ABSTRACT FROM AUTHOR]

Background: Guidelines previously recommended use of dual antiplatelet therapy, statins, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEI/ARB) and beta blockers (five classes of drugs) in patients without contraindications or intolerance after acute coronary syndrome (ACS). However, recent guidelines have taken a more nuanced view regarding the use of ACEI/ARB and beta blockers. Our aim was to develop a composite post-discharge medication indicator, based on available evidence, to support quality improvement.Methods: 4,112 consecutive post-ACS patients who underwent coronary angiography and left ventricular ejection fraction (LVEF) assessment in 2015-16 were recorded in the All New Zealand ACS Quality Improvement (ANZACS-QI) registry. Patients receiving coronary artery bypass grafting were excluded. Three composite indicator algorithms that took into account known contraindications/intolerances were compared across NZ District Health Boards (DHBs): RESULTS: Overall and individual DHB performance was highest (74%, DHB range 52-84%) when reported using the NHFA/CSANZ indicator, and slightly lower (69%, DHB range 48-78%) on the ANZACS-QI indicator. Performance was lowest using the older five-drug-class indicator (65%, DHB range 48-77%).Conclusions: We have developed a composite post-discharge medication indicator appropriate for use in identifying gaps in evidence-based management across NZ, which is now being reported regularly to DHBs.

Background: Cohort studies of STEMI patients have reported that over 30% receive no reperfusion. Barriers to greater use of reperfusion in STEMI patients require further elucidation.Methods: We collected data on STEMI patients with no reperfusion as part of the SNAPSHOT ACS Registry, which recruited consecutive ACS patients in 478 hospitals throughout Australia and New Zealand during 14-27 May 2012.Results: Of 4387 patients enrolled, 419 were diagnosed with STEMI. Primary PCI (PPCI) was performed in 160 (38.2%), fibrinolysis was used in 105 (25.1%), and 154 (36.7%) had no reperfusion. Patients with no reperfusion had a mean age of 70.3±15.0 years compared with 63.1±13.5 in the reperfusion group (p<0.0001). There were more females in the no reperfusion group (37.1% v 23.0% p=0.002) and they were significantly more likely to have prior PCI or CABG, heart failure, atrial fibrillation, chronic kidney disease and other vascular disease, and to be nursing home residents (all p<0.05). Patients without reperfusion had a significantly higher mortality in hospital (11.7% v 4.9%, p=0.011). In 370 patients who presented within 12hours, 28 had early angiography without PCI, which was considered an attempt at reperfusion. Therefore reperfusion was attempted in 293 of 370 eligible patients (79.2%).Conclusion: Of consecutive STEMI patients, 36.7% did not receive any reperfusion and they had a higher risk of death in hospital. In eligible patients, reperfusion was attempted in 79.2%. National strategies to encourage earlier medical contact and greater use of reperfusion in eligible patients may lead to better outcomes.
