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

Area of Science:

• Cardiology
• Medical Protocols
• Patient Safety

Background:

• Venous thromboembolism (VTE) is a significant risk for cardiology patients.
• Noncompliance with VTE prophylaxis guidelines is a persistent issue.
• Effective VTE prevention is critical for reducing morbidity and mortality.

Purpose of the Study:

• To evaluate the impact of a guideline-based protocol on VTE prophylaxis compliance.
• To assess the rate of VTE prophylaxis in high-risk cardiology inpatients.
• To identify persistent gaps in VTE prevention despite protocol implementation.

Main Methods:

• Conducted 10 single-day audits in a cardiology inpatient unit.
• Included 420 high-risk patients for VTE (median age 66 years).
• Compared VTE prophylaxis rates before and after protocol introduction.

Main Results:

• Pre-protocol, 36% of patients did not receive VTE prophylaxis.
• Post-protocol, 26% of patients still did not receive VTE prophylaxis (P = 0.024).
• The protocol significantly increased compliance but did not eliminate noncompliance.

Conclusions:

• High rates of noncompliance with VTE prophylaxis guidelines persist in cardiology units.
• Guideline-based protocols can improve VTE prophylaxis adherence.
• Further interventions are needed to ensure all high-risk patients receive appropriate VTE prevention.
