Question special
Chief Resident

It seems that a large portion of you study population falls into the low C-PTP group, which ended up with the most dramatic reduction in CT scan use. I’m wondering about the signs and symptoms that led these patients to be included in the study. Are these signs and symptoms ones that would lead any physician to consider a PE as a leading differential? If all patients that present with any sign or symptom of PE (hypoxia, tachycardia, etc.) are included, I imagine this would bias your results. Thank you again for participating with us!
