Mr Ryan Posselt
ST-segment elevation myocardial infarction (STEMI) is a time critical, life-threatening medical emergency. Time to reperfusion is the primary predictor of clinical outcomes. This study aims to benchmark the time-to-treatment performance of emergency systems in southern Tasmania, as measured by first medical contact to balloon time (FMC2B), for patients undergoing percutaneous coronary intervention (PCI) for STEMI against the relevant guidelines.
Study participants were identified using existing medical coding systems. A retrospective chart audit of this patient group was undertaken to identify patients whose treatment involved transport by ambulance and subsequent emergent PCI. Various pre-hospital and in-hospital time points were taken and measured against guideline recommendations. A multivariate linear regression analysis was used to investigate the relationship between time of day and time-to-treatment.
