Caprini VTE risk score (surgical patients)
Adds Caprini risk-factor points for venous thromboembolism in surgical patients and gives the ACCP 2012 risk category (very low, low, moderate, high) with the estimated baseline VTE risk without prophylaxis..

Implementation notes
ACCP calls the table "our adaptation" of Caprini 2005 and 1991. Items are scored exactly as listed, so "medical patient at bed rest" (1) and "confined to bed > 72 h" (2) are separate rows. Surgery and age are one choice each. The ACCP narrative text instead says very low is 0–1 point and low is 2 points, and the table and recommendations are followed here. Bahl 2010 abstract incidences by level (0%, 0.70%, 0.97%, 1.94%) agree with Table 5 after rounding. In plastic and reconstructive surgery the same score carries a lower risk (ACCP Table 5: 3–4 gives 0.6%, 5–6 gives 1.3%, 7–8 gives 2.7%, above 8 gives 11.3%).
