Modified Wells Scoring System
| Clinical Characteristic | Score |
|---|---|
| Clinical Probability of Pulmonary Embolism | Score |
| Low | 0-1 |
| Intermediate | 2-6 |
| High | ≥6 |
Secondly, is all well with the Wells score?
The Wells criteria is a clinical scoring process used in the diagnosis of acute pulmonary embolism (PE) and deep vein thrombosis (DVT).
Hereof, what does a high Wells score mean?
The bottom line
Your Wells score can help your doctor determine your risk of developing DVT. If your score indicates you have a higher risk, your doctor may suggest additional testing to look for a blood clot.
What does D-dimer measure?
D-dimer tests are used to check for blood clotting problems. Blood clots can cause health problems, such as: Deep vein thrombosis (DVT) Pulmonary embolism (PE)
What is 2 level PE Wells score?
two level Wells score for DVT
| Factor | Points |
|---|---|
| collateral superficial veins (non-varicose) | 1 |
| pitting oedema (confined to symptomatic leg) | 1 |
| swelling of entire leg | 1 |
| localised tenderness along distribution of deep venous system | 1 |
What is a positive D-dimer?
A positive or elevated D-dimer test result may indicate that you have a blood clotting condition, but it doesn’t guarantee that you have one. A D-dimer test can’t reveal what type of clotting condition you have or where the clot is located in your body.
What is PTP score?
The clinical pretest probability score (PTP) is a useful tool for selecting patients for further diagnostic examina- tion for DVT. The PTP score, developed by Well et al,8 is calculated from clinical and historical data to stratify pa- tients into low, moderate, and high risk of DVT.
What is the normal range of D-dimer test?
A normal D-dimer is considered less than 0.50. A positive D-dimer is 0.50 or greater. Since this is a screening test, a positive D-Dimer is a positive screen.
What is the probability of a PE in a patient with a Wells score of 1?
Narration of the flowchart:
Wells scores (Table 1) of 0-2 are considered low PE probability (<3.6% risk of PE). Scores of 3-6 points are considered moderate PE probability (<20.5% risk of PE) and scores of 6 points or greater indicate a high probability for PE (up to 66.7% risk of PE).
When do you do D-dimer Wells score?
SUMMARY. In summary, the data suggest that when patients present in a clinic setting with a suspected first DVT, high-sensitivity D-dimer testing should be combined with Wells scoring to determine which patients need ultrasound imaging and which may be reassured with no further intervention.
