Comparison of the proportion of common chest (CC) symptom–related visits associated with computed tomography orders in US emergency departments between 1997 to 1999 and 2005 to 2007. P < .0001 for all comparisons. *Individual symptom totals do not total overall CC symptom–related visit total because some visits were associated with one than one CC symptom.

Comparison of proportion of diagnostic categories of CC symptom–related visits in US emergency departments between 1997 to 1999 and 2005 to 2007 (n = 17,098). Results have been adjusted for sex, age, race, insurance, and region.
