Patients Admitted With An Acute Coronary Syndrome In New Zealand In 2007: Results Of A Second Comprehensive Nationwide Audit And A Comparison With The First Audit From 2002
NEW ZEALAND MEDICAL JOURNAL(2010)
摘要
Aims To audit all patients admitted to a New Zealand (NZ) Hospital with an acute coronary syndrome (ACS) over a 14-day period, to assess their number, presentation type and patient management during the hospital admission and at discharge. To compare patient management in 2007 with the 1 st NZ Cardiac Society ACS Audit from 2002.Methods We updated the established NZ ACS Audit group of 36 hospitals to 39 hospitals now admitting ACS patients across New Zealand. A comprehensive data form was used to record individual patient information for all patients admitted between 00.00 hours on 14 May 2007 to 24.00 hours on 27 May 2007.Results 1003 patients, 9% more than in 2002 (n=930), were admitted with a suspected or definite ACS: 8% with a ST-segment-elevation myocardial infarction (STEMI), 41% with a non-STEMI (NSTEMI), 33% with unstable angina pectoris (UAP), and 17% with another cardiac or medical condition. In 2007 non-invasive risk stratification following presentation remained similar to 2002 and was suboptimal: exercise treadmill tests (21% vs 20%, p=0.62), echocardiograms (19% vs 20%, p=0.85). An increase in utilisation of coronary angiography was noted (32% vs 21%, p<0.0001). In hospital revascularisation rates remained low in patients with diagnosed ACS (n=828): STEMI (45%), NSTEMI (23%) and UAP (7.3%). In comparison to 2002, changes were noted in revascularisation techniques with percutaneous coronary intervention (PCI) performed in 19% vs 7% (p<0.0001). The use of coronary artery bypass grafting (CABG) remained extremely low: 2.8% vs 3.5% (p=0.20). The use of hospital and discharge medication of proven benefit was also limited.Conclusions A collaborative group of clinicians and nurses has performed a second nationwide audit of ACS patients. Despite a small increase in access to cardiac angiography, guideline recommended risk stratification following the index suspected ACS admission with a treadmill test or cardiac angiogram occurred in only 1 in 2 (48%) patients. Furthermore, in patients with a definite ACS, levels of revascularisation are low. (PCI 19%, CABG 2.8%). These aspects of care remain of significant concern and have not substantially changed in 5 years. There remains an urgent need to develop a comprehensive national strategy to improve all aspects of ACS patient management.
