Impact of a rapid access chest pain clinic in Singapore to improve evaluation of new-onset chest pain.

Background: Chest pain (CP) accounts for 5% of emergency department (ED) visits, unplanned hospitalisations and costly admissions. Conversely, outpatient evaluation requires multiple hospital visits and longer time to complete testing. Rapid access chest pain clinics (RACPCS) are established in the UK for timely, cost-effective CP assessment.
