Case Discussion
Pulmonary Embolism With sPESI 0: What Still Has to Be True Before ED Discharge?
A zero sPESI score estimates low short-term clinical risk; it is not a discharge order. This case shows how teams pair the score with current physiology, treatment barriers, medication access, and follow-up before choosing home care.
Study Tips
Wells Score for Pulmonary Embolism: The Point-Scoring Traps That Change D-Dimer vs CTPA
A Wells score is only useful when every point is earned. Learn how to assess DVT signs, immobility, and clinical judgment accurately, then choose D-dimer, CTPA, or V/Q imaging.

Modified Wells Score for Pulmonary Embolism: Score Precisely, Then Choose CTPA
A high Wells score should move the clinician toward definitive imaging—not reflexive D-dimer testing. Work through the score carefully, identify common traps, and choose the correct next test.
