    Abstract:
    BACKGROUND: The aim of the study was to audit the impact of cardiac nurse practitioner led thrombolysis as a method of reducing call to needle times for acute myocardial infarction (AMI) in a single district hospital. METHODS: This was a prospectively planned, observational study, comparing time delay between arrival at hospital and the administration of thrombolysis ('door to needle' time) in patients presenting with AMI in a district general hospital serving a population of 270000. The 6 months before and 6 months after initiation of the scheme were compared. RESULTS: There were 151 consecutive patients (undergoing 163 thrombolysis episodes). The median door to needle time fell from 60 min (range 42-110 min) to 30 min (range 20-61 min) (p<0.01). In those patients eligible for immediate thrombolysis the number of cases treated within 30 min of arrival rose from 10/58 (17 per cent) to 48/64 (75 per cent) (p<0.01). The proportion of cases where there was an initial delay as a result of non-diagnostic ECG or possible contra-indication to therapy remained constant, 20/78 (25 per cent) cases before and 21/85 (25 per cent) cases after initiation of the scheme. The number of cases of inappropriate thrombolysis fell from 73 per cent to 30 per cent. CONCLUSION: The provision of i.v. thrombolysis by cardiac nurse practitioners is safe and should be considered as a method for achieving acceptable door to needle times in the management of acute myocardial infarction.
