door-to-balloon time
Quality metric measuring time from hospital arrival to balloon inflation during primary PCI for STEMI.
Full Definition
Door-to-balloon time is a critical quality indicator in STEMI care that measures the interval between a patient's arrival at the hospital ('door') and the inflation of the angioplasty balloon in the culprit vessel ('balloon'). Current guidelines recommend achieving door-to-balloon times of 90 minutes or less for optimal outcomes. This metric encompasses emergency department triage, ECG interpretation, catheterisation laboratory activation, patient preparation, and the actual intervention procedure.
Usage
Usage note: Always hyphenate. Measured in minutes. Sometimes abbreviated as D2B in informal contexts.
