Key result
A standardized 2-part key question elicited symptom onset times matching the very first symptom (median difference 0 minutes) and preceding the realization of illness by a median of 30 minutes.
Why the study?
Does a standardized 2-part key question accurately measure out-of-hospital delay in adult patients presenting to the ED with chest pain compared to alternative questions?
Population
135 adult patients presenting to emergency departments with chest pain, mean age 62 +/- 16 years, 59% male.
Comparison
Standardized 2-part 'key' question about acute… vs Alternative questions about symptom perception…

Does a standardized 2-part key question accurately measure out-of-hospital delay in adult patients presenting to the ED with chest pain compared to alternative questions?
Hedges et al. (1998) conducted a cross-sectional in chest pain (n=135). Standardized 2-part key question (Key-Q) vs. Alternative questions (Q1-Q4) was evaluated on Median differences in minutes between alternative question times and the Key-Q response. A standardized 2-part key question elicited symptom onset times matching the very first symptom (median difference 0 minutes) and preceding the realization of illness by a median of 30 minutes.
