Australia's first cardiac emergency department: Patient profile, activity and performance in the initial 6 months

To profile the initial 6-month experience at the Victorian Heart Hospital (VHH) cardiac emergency (CE). The primary objective was to describe VHH CE patient characteristics, including presenting complaint, final diagnosis and disposition. Secondary objectives were to report on patient numbers, patient source and quality indicator performance including ambulance off-load by 40 min, waiting time and length of stay (LOS).

A retrospective review included all patients who presented to the VHH CE from 9 March 2023 to 8 September 2023. Patient reports containing the relevant clinical information were generated from the CE electronic medical record system. Diagnoses of MI were checked for accuracy by full record review.

There were 3303 CE presentations in the first 6 months of operation, of which 6% were transferred from other sites. Median age was 65 years (interquartile range [IQR]: 53-77), 56% were males; the most common presenting complaints were presumed cardiac chest pain (67%) and arrhythmia (17%). The admission, discharge and transfer rates were 38%, 54% and 8%, respectively. In total, 15% were diagnosed with MI. The most common diagnoses for discharged and admitted patients were non-specific chest pain (57%) and ST-elevation MI (22%), respectively. Ambulance off-load by 40 min was met for 96%. Median waiting time was 6 min (IQR: 3-10). Median CE LOS for discharged and admitted patients was 3.2 h (IQR: 2.5-4.0) and 3.7 h (IQR: 1.8-6.0), with 75% and 56% being <4 h, respectively.

The population predominantly had cardiovascular disease as expected. Some performance indicators, including ED LOS, were identified as requiring intervention.
