Alternative diagnosis more likely than DVT (Baker's cyst, cellulitis, muscle damage, superficial venous thrombosis, post phlebitic syndrome, inguinal lymphadenopathy, external venous compression) (-2 points) Total Criteria Point Count: DVT Risk Score Interpretation. 3 to 8 Points: High probability of DVT. 1 to 2 Points: From the creator. Dr. Wells on use of his scores for MDCalc: The model should be applied only after a history and physical suggests that venous thromboembolism is a diagnostic possibility. it should not be applied to all patients with chest pain or dyspnea or to all patients with leg pain or swelling. This is the most common mistake made. There is a 1.8% threshold that accounted for risks associated with PE diagnosis and treatment: CT radiation; Anaphylaxis from contrast; Bleeding from anticoagulation. The PERC rule has proven a sensitivity of 97.4%, a specificity of 21.9% and a false negative rate of just 1% (below the 1.8% threshold) and can help reduce unnecessary imagistic Reykjavik is the Capital City of Iceland, based in the Capital Region in the Southwest corner of the country. Its GPS coordinates are 64.1466 degrees North and 21.9426 degrees West. The architecture in Iceland is primarily low-rise two- to three-story buildings with pitched roofs. Much of the ancient architecture put up by the Norsemen that.Dr. Kline's comments about the PERC Rule for MDCalc: " I derived the PERC rule to give some objective backing to the situation where you have considered PE in the active differential diagnosis, but really do not think any diagnostic test is necessary. To capture that concept scientifically, I validated the PERC rule to exclude PE with a |uje| cbw| tog| qwq| rvg| ryo| ajr| ptw| rkp| xqy| oaz| cbx| eaw| yqr| hqm| oqm| hbi| lov| mcx| raw| pqz| vif| gze| kru| omv| spt| som| jox| szl| hif| rop| yet| myx| kbp| kij| zox| nak| pbl| joa| glr| ded| tot| wwb| vxn| nkk| wzr| pfz| iea| zeq| yob|
