The Venous Thromboembolic and Bleeding Score Calculator is a user-friendly online tool designed to help assess the balance between the risk of blood clot formation and the potential for bleeding in a patient. Venous thromboembolism (VTE) refers to a condition where a blood clot forms in a vein, often in the legs (deep vein thrombosis) or lungs (pulmonary embolism). While preventing VTE is important, some patients also have a high risk of bleeding, which must be carefully considered before starting or continuing anticoagulant (blood-thinning) therapy.
This calculator is based on key clinical indicators that research has shown to be associated with increased risks of either clotting or bleeding. By selecting the options that apply to a patient—such as active cancer, uncontrolled high blood pressure, low hemoglobin levels (anemia), a past history of bleeding, impaired kidney function, or age over 60—the calculator automatically adds up a total score.
Each factor is assigned a specific number of points based on its relative risk contribution. A higher total score suggests a greater risk of bleeding if anticoagulants are used, while also indicating that the patient may be at significant risk for clot formation. The purpose of this score is not to give a diagnosis, but rather to support informed clinical decision-making.
It is important to remember that this tool is intended for educational and informational purposes. It should be used alongside professional medical advice, a full clinical evaluation, and shared decision-making between the patient and healthcare provider. The score can help raise awareness of risk factors but should never be the sole basis for starting or stopping treatment.
If you or someone you are caring for has any of the health issues listed in this calculator or you are concerned about blood clotting or bleeding, be sure to consult a qualified medical professional for a thorough assessment and personalized care.
The Venous Thromboembolic and Bleeding Score is important because it helps identify patients who are at increased risk of developing dangerous blood clots or experiencing serious bleeding. Both conditions can have life-threatening consequences, especially in individuals with complex health issues such as cancer, kidney problems, or a history of bleeding.
Blood clots can block blood flow in vital areas like the lungs or brain, leading to conditions such as pulmonary embolism or stroke. On the other hand, treating or preventing clots often requires blood-thinning medications, which can increase the risk of bleeding. This creates a delicate balance—treating one risk might worsen the other.
By using this score, doctors and healthcare providers can better understand the overall risk profile of a patient. It allows them to make more informed choices about starting, continuing, or adjusting anticoagulation therapy. For example, a patient with a high bleeding score may require extra monitoring or alternative treatment strategies.
The score also encourages early recognition of risk factors. For patients, this can mean earlier lifestyle changes, better communication with healthcare providers, and more personalized treatment plans. It helps avoid a “one-size-fits-all” approach to care by highlighting the individual needs of each patient.
In short, this score is a useful tool that brings clarity to complex medical decisions. It supports safer and more effective treatment by identifying those who need special attention and a tailored approach to preventing both clots and bleeding events.
The Venous Thromboembolic and Bleeding Score Calculator is intended for use by healthcare professionals such as doctors, nurses, and clinical staff involved in patient care. It helps them quickly assess the risk of blood clots and bleeding based on a patient’s medical history and current health status.
While this tool is designed primarily for medical use, patients and caregivers may also find it helpful for understanding the factors that contribute to clotting or bleeding risks. However, the results should always be interpreted in the context of a full medical evaluation by a qualified professional.
This calculator is especially useful for:
If you are a patient concerned about your own risk, it's best to use this calculator with the guidance of your healthcare provider. They can help interpret your score and decide on the safest and most effective next steps for your care.
Using the Venous Thromboembolic and Bleeding Score Calculator is simple and takes only a few moments. It’s designed to be a quick, user-friendly tool to help estimate a patient’s risk of blood clots and bleeding based on known clinical risk factors.

Important Notes:
Once you get the score, it can help guide clinical decisions such as whether to start blood-thinning treatment, adjust medication doses, or consider additional monitoring. However, remember that this calculator is a support tool and does not replace medical advice or diagnostic testing.
For the most accurate use, healthcare providers should interpret the results alongside a full clinical assessment and patient history.
The calculator works by assigning a specific number of points to each medical condition or risk factor that may increase the chances of venous thromboembolism (VTE) or bleeding. Below is a breakdown of the components and the points they contribute:
Patients with an active cancer diagnosis are at a significantly higher risk for blood clots. This includes those currently undergoing treatment or diagnosed within the past 6 months. If this applies, 2 points should be added to the total score.
Male patients with a systolic blood pressure of 140 mm Hg or higher are considered to have uncontrolled hypertension. This condition can increase both clotting and bleeding risks. If present, add 1 point.
Anemia is defined as low hemoglobin levels (less than 130 g/L in men and less than 120 g/L in women). This condition can be a sign of ongoing or previous bleeding and adds 1.5 points to the score.
A past event of major or clinically relevant non-major bleeding suggests a higher risk of future bleeding episodes, especially during anticoagulant therapy. This history adds 1.5 points.
Renal dysfunction, defined as a creatinine clearance (CrCl) between 30 and 60 ml/min, can affect how medications are processed and increase bleeding risk. If applicable, 1.5 points are added.
Advancing age is a well-known risk factor for both blood clots and bleeding complications. Patients who are 60 years or older receive 1.5 points in the scoring system.
Each selected factor increases the total score, which helps healthcare providers evaluate the overall bleeding and thromboembolic risk before making treatment decisions.
Once you've selected all the applicable risk factors in the calculator, the total score is automatically displayed. This score reflects the patient's combined risk of developing venous thromboembolism (VTE) and experiencing bleeding complications, especially if anticoagulant (blood-thinning) therapy is being considered.
The higher the score, the greater the overall risk. While the calculator does not give a specific diagnosis or treatment recommendation, it helps guide clinical decisions by highlighting risk levels.
These ranges are general guidelines. Every patient is different, and the score should always be interpreted in the context of the full medical history, current condition, and treatment goals.
If you're a patient using this tool to better understand your health, share your score with your doctor. They can explain what it means in your specific case and help you decide on the best next steps.
After calculating your total score using the Venous Thromboembolic and Bleeding Score Calculator, the next step is to use this information as a guide—not a final decision. This score is designed to help start an informed conversation between you and your healthcare provider about your personal risk level and the best course of action.
The calculator is a helpful tool, but it's just one piece of the puzzle. Use your score to guide better conversations, smarter decisions, and more personalized care. It’s always best to take a proactive role in your health—but with expert guidance along the way.
