Implementation of a Risk-Based Heparin Protocol for Postpartum Venous Thromboembolism Prevention

Area of Science:

• Obstetrics and Gynecology
• Pharmacology
• Public Health

Background:

• Venous thromboembolism (VTE) is a significant risk in the postpartum period.
• Effective prevention strategies are crucial for maternal safety.
• Low-molecular-weight heparin (LMWH) is a key agent in VTE prophylaxis.

Purpose of the Study:

• To evaluate the impact of a risk-based LMWH protocol on VTE prevention in postpartum women.
• To assess changes in LMWH administration rates, VTE incidence, and complication rates.
• To determine physician adherence to the new protocol.

Main Methods:

• Retrospective cohort study of 9,766 deliveries over three years (2013-2015).
• Comparison of outcomes before and after implementation of a risk-based enoxaparin protocol.
• Analysis of VTE, wound complications, readmissions, and protocol adherence rates.

Main Results:

• Enoxaparin administration increased from 0.28% to 33.46% post-protocol implementation (P<.001).
• No significant differences were observed in VTE incidence (0.16% vs. 0.15%) or wound complications (0.82% vs. 0.91%).
• Physician adherence to the protocol was high (89.5%), but readmissions showed a slight increase (P=.02).

Conclusions:

• The risk-based LMWH protocol led to widespread enoxaparin use in postpartum women with high adherence.
• The protocol appeared safe, with no increase in VTE or wound complications.
• Larger studies are required to definitively assess the protocol's efficacy on thromboembolic disease and wound issues.
