Wells' Criteria for Assessment of Pretest Probability for Pulmonary Embolism
Suspected DVT
An alternative diagnosis is less likely than PE
Heart rate >100 beats per minute
Immobilization or surgery in the previous four weeks
Previous DVT or PE
Hemoptysis
Malignancy (on treatment, treated in the past six months or palliative)
Score
Mean probability of PE
Interpretation of risk
Warkentin's Point System
Thrombocytopenia
>50% fall or platelet nadir 20-100K
30-50% fall or platelet nadir 10-19K
<30% fall or platelet nadir <10K
Timing of Platelets Drop or Other Sequelae
Onset between day 5 and day 10 or <1 day if recent exposure within 100 days
Onset aftr day 10 or not clear (missing platelet counts)
Fall too early without recent heparin exposure
Thrombosis or Other Sequelae
New thrombosis; skin necrosis, acute systemic reaction following heparin bolus
Progressive or recurrent thrombosis; erythematous skin lesions; suspected thrombosis not yet proven
None
Other Causes of Thrombocytopenia
None evident
Possible other casuses
Definite other causes present
