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 (PAMI-II) 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.
