Caprini Risk Assessment Tool for Venous Thromboembolism Risk
The Caprini risk assessment tool is a validated scoring system used to stratify venous thromboembolism risk in surgical and hospitalized patients based on individual risk factors. It assigns weighted points across categories such as age, prior thrombotic history, comorbidities and planned procedure type. Healthcare professionals can use the resulting score to guide decisions on the intensity of thromboprophylaxis required.
| IF the Total score is | Your Patient is in: |
| 0-1 | Low Risk |
| 2 | Moderate Risk |
| 3-4 | Higher Risk |
| 5 or more | Highest Risk |
| Total Risk Factor Score | Risk Level | Incidence of DVT | Prophylaxis Regimen |
| 0-1 | Low Risk | 2% |
|
| 2 | Moderate Risk | 10-20% |
|
| 3-4 | Higher Risk | 20-40% |
|
| 5 or more | Highest Risk | 40-80% |
|
| If the Total Risk Factor Score is 0 or 1, in this case patient is in low risk to develop DVT. | If Total Risk Factor Score is 2, in this case patient is in Moderate risk to develop DVT. | If the Total Risk Factor Score is 4, in this case patient is in Higher risk to develop DVT. | If the Total Risk Factor Score is 5 or more, in this case patient has the highest risk to develop DVT. |
| The Prophylaxis Regimen is the Early ambulation. | The Prophylaxis Regimen is to choose (SCD) OR Heparin 5000 units SQ BID. | The Prophylaxis Regimen to choose one medication with or without (SCD). | The Prophylaxis Regimen to choose medication PLUS (SCD). |

The Caprini tool is used to stratify a patient's individual risk of developing venous thromboembolism, particularly in the surgical and hospitalized patient setting, by assigning weighted points to multiple risk factors. The resulting total score categorizes patients into risk tiers that guide thromboprophylaxis decisions. It is one of several validated tools used for structured perioperative risk assessment.
The Caprini score incorporates factors such as patient age, body mass index, prior history of venous thromboembolism, active malignancy, planned surgery type and duration, and other relevant comorbidities. Each factor carries a different weighted point value based on its associated thrombotic risk. The cumulative score determines the overall risk category assigned to the patient.
Higher Caprini scores generally indicate a greater need for pharmacologic or mechanical thromboprophylaxis, with specific score thresholds often used to guide the intensity and duration of preventive measures. Lower-risk patients may require only early mobilization without pharmacologic prophylaxis. Healthcare professionals should apply the score alongside local institutional protocols and individual patient bleeding risk when finalizing a prevention plan.
