Abstract
Data for low-risk ST-elevation myocardial infarction (STEMI) patients in the Essex cardiothoracic centre (CTC) during a three-month period were evaluated and the average duration of admission was calculated to be 67.2 hours. The data were sifted by applying Second Primary Angioplasty in Myocardial Infarction (PAMIII) criteria for low-risk STEMI patients who could be safely discharged after 48 hours. After application of a proforma as a quality improvement intervention tool, data were re-assessed and the average time of admission observed for a similar cohort of patients dropped down to an average of 55.2 hours. Overall, there was a 13% average increase in rate of early discharge for low-risk STEMI patients.
