    Abstract:
    AIMS: To audit all patients presenting to a New Zealand hospital with a myocardial infarction or unstable angina (an acute coronary syndrome [ACS]) over a 14-day period, to assess their number, presentation type and patient management during the hospital admission. METHODS: We formed a group of clinicians to lead the local audit process with one representative for each hospital (n=36) that admitted ACS patients. A comprehensive data form was used to record individual patient information for patients admitted between 0000 hours on 13 May 2002 to 2400 hours on 26 May 2002. RESULTS: 930 patients were admitted with a suspected or definite ACS: 11% with a ST-segment-elevation myocardial infarction (STEMI), 31% with a non-STEMI, 36% with unstable angina pectoris (UAP), and 22% with another cardiac or medical diagnosis. Cardiac investigations were limited: echocardiogram (20%), exercise treadmill test (20%), cardiac angiogram (21%). In-hospital revascularisation rates were low for those patients with a definite presentation with an ACS (STEMI, non-STEMI, UAP, n=721). Percutaneous coronary intervention (PCI) rates were 13%, 8%, and 4%--with coronary artery bypass grafting (CABG) rates being 4%, 3%, and 4% respectively. The use of discharge medications of proven benefit was also generally low (n=695): aspirin (82%), clopidogrel (8%), beta-adrenergic blockers (63%), angiotensin converting enzyme (ACE) inhibitors (43%), and statins (55%). CONCLUSIONS: A collaborative group of clinicians has performed a nationwide audit of acute coronary syndrome patients, which has demonstrated low levels of investigations, evidence-based treatments, and revascularisation. There is a need for a comprehensive national strategy--particularly for continuing audit of the treatment of patients presenting with a suspected or definite acute coronary syndrome to a New Zealand hospital.
