Caprini Score Calculator

Caprini Score Calculator for Hematology. For the named historical CHEST nonorthopedic surgical framework, 0 is very low, 1-2 low, 3-4 moderate and >=5 high risk. The category does not select a prophylactic drug, dose, duration or approach to bleeding risk.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

Interpret a completed 2005 Caprini total using the CHEST 2012 general/abdominal-pelvic surgical risk strata: 0, 1-2, 3-4 and at least 5. This is a documented-total companion, not a reproduced risk-factor questionnaire.

When to use this calculator

Use only after the named source assessment is complete and documented. This companion interprets entered totals or subtotals; it does not recreate missing source items or authorize a treatment decision.

Inputs used

  • Documented 2005 Caprini total
  • Completed instrument and population

Clinical interpretation

For the named historical CHEST nonorthopedic surgical framework, 0 is very low, 1-2 low, 3-4 moderate and >=5 high risk. The category does not select a prophylactic drug, dose, duration or approach to bleeding risk.

Worked example

Fictional teaching case. Documented 2005 Caprini total: 11; Completed instrument and population: 2005 Caprini assessment in adult nonorthopedic surgery. Result: 11 points. High historical CHEST nonorthopedic-surgery risk category. Risk category is not a prophylaxis prescription. Bleeding risk, operation, mobility, renal function and the applicable current local pathway must be considered separately.

Limitations and safety notes

Do not combine versions or apply this interpretation to orthopedic, medical, obstetric or pediatric populations. Obtain and administer the appropriate authorized form. Procedure-specific guidance may use different thresholds; no drug, dose or duration is selected.

Frequently asked questions

Is this a complete Caprini risk-factor assessment?

No. It interprets a documented 2005 total for the specified adult nonorthopedic-surgery setting. Complete an authorized, version-specific assessment first; omitted factors must not be presumed absent.
