Key result
Use of PERC and Wells/D-dimer clinical decision rules could have avoided 9.2% and 13.8% of CT-PA procedures, respectively, in ED patients with suspected pulmonary embolism.
Why the study?
Does the application of Wells/D-dimer or PERC reduce unnecessary CT-PA procedures in adult ED patients with suspected PE?
Cohort (n=152)
Does the application of Wells/D-dimer or PERC reduce unnecessary CT-PA procedures in adult ED patients with suspected PE?
Application of PERC and Wells/D-dimer criteria could safely avoid approximately 9-14% of CT-PA procedures in ED patients with suspected PE, potentially reducing ED length of stay.
No takes yet. Share an insight, caveat, or question.
May reduce CT-PA in low-risk ED patients; hypothesis-generating and requires prospective validation before adoption.
Crichlow et al. (2012) conducted a cohort in Suspected pulmonary embolism (n=152). PERC and Wells/D-dimer clinical decision rules was evaluated on Pulmonary embolism by CT-PA or 90-day follow-up. Use of PERC and Wells/D-dimer clinical decision rules could have avoided 9.2% and 13.8% of CT-PA procedures, respectively, in ED patients with suspected pulmonary embolism.
