This international cluster-randomised controlled trial evaluated whether a faster 0/1 hour pathway for diagnosing myocardial infarction in emergency departments is as safe and more efficient than the standard 0/3 hour pathway. The study found that the 0/1 hour pathway met non-inferiority criteria for 30-day safety outcomes, meaning it was equally safe as the longer protocol. However, contrary to expectations, the faster pathway did not reduce patients' length of stay in the emergency department compared to the standard approach.
Why it matters
These findings have important implications for emergency departments considering implementing faster diagnostic protocols for suspected heart attacks. While the 0/1 hour pathway is safe, hospitals should not expect it alone to improve patient flow or reduce overcrowding without additional systematic changes to emergency department processes.
Understand the Science
Implementation of the 0/1 h pathway met the prespecified non-inferiority criterion for the 30-day composite safety outcome but did not shorten emergency department length of stay compared with the 0/3 h pathway. In this setting, implementation of the 0/1 h pathway alone should therefore not be expected to improve emergency department throughput.
