Delay From Symptom Onset to Hospital Presentation for Patients With Non–ST-Segment Elevation Myocardial Infarction
Why the study?
What factors are associated with delay from symptom onset to hospital presentation, and how does delay time affect in-hospital mortality in patients with non-STEMI?
Structured PICO
What factors are associated with delay from symptom onset to hospital presentation, and how does delay time affect in-hospital mortality in patients with non-STEMI?
P
Population
104,622 patients with non-STEMI enrolled at 568 hospitals participating in the CRUSADE National Quality Improvement Initiative from January 1, 2001, to December 31, 2006.
O
Outcome
Secular trends and factors associated with delay time, and the association of delay time with in-hospital mortalityhard clinical
Delay times from symptom onset to hospital presentation for non-STEMI patients remain long and unchanged, highlighting the need for continued efforts to encourage early presentation.

Implication
Stable long delays in non-STEMI presentation were associated with mortality differences; leaves open whether public education shortens times or improves outcomes.
