Disparities in menstrual bleeding management during acute venous thromboembolism treatment: A review of UK practice and a call for clinical studies

Abstract

Background

Heavy menstrual bleeding (HMB) is a significant clinical burden for premenopausal individuals treated with anticoagulation for acute venous thromboembolism (VTE). Despite its prevalence, HMB management remains poorly studied, with wide variation in clinical practice.

Objectives

The current study aimed to explore current UK practices in managing HMB in anticoagulated individuals and identify areas requiring clinical research to address disparities.

Methods

A national survey was conducted among haematology consultants and consultant clinical pharmacists managing anticoagulated patients. The survey focused on management strategies, including anticoagulant selection, use of tranexamic acid (TXA), contraceptive options, and anticoagulation interruption.

Results and conclusion

Responses were collected from 102 participants, across the UK. Apixaban was the preferred anticoagulant for patients with HMB, followed by LMWH then dabigatran. Timing of TXA initiation varied widely between respondents, with (35.3 %) prescribing it any time after anticoagulation initiation, (11.8 %) delaying TXA use for 3 months, and (7.8 %) would not give it at all. (47.1 %) of respondents advise to discontinue oestrogen containing contraceptives in patients with acute VTE. Almost all respondents never or rarely stop anticoagulation for a patient with HMB and recent VTE ≤4 weeks. (62.7 %) of respondents showed their willingness to participate in clinical studies to study TXA use in the setting of acute VTE ≤4 weeks in anticoagulated individuals.

This study highlights significant variations in HMB management during anticoagulation for acute VTE. Disparities raise concerns about health inequities and underscore the urgent need for prospective clinical trials to improve patient outcomes.
