Venous Thromboembolism Prophylaxis on a Cardiology In-Patient Unit: A Surprising Result?

To determine whether a guideline-based protocol improves compliance with venous thromboembolism (VTE) prophylaxis guidelines, 10 single-day audits of a cardiology inpatient unit were performed. All patients at high risk for VTE were included (n = 420; male/female = 282/138; median age, 66 ± 14 years). Before the protocol, 36% of patients were not receiving VTE prophylaxis; after the protocol, 26% did not receive prophylaxis (P = 0.024). In conclusion, there is a high rate of noncompliance with accepted guidelines for the prevention of VTE. The introduction of a guideline-based protocol significantly increased compliance, but a substantial proportion of patients still did not receive VTE prophylaxis despite meriting such therapy.
