Clinical context

Caprini is a cumulative VTE risk model widely used in surgical populations. Higher totals correlate with higher observed VTE risk and help guide prophylaxis intensity and duration decisions. Because multiple Caprini versions are used in practice (for example, 2005 vs later updates), use one version consistently within your protocol.
