Background And Objectives:
Evidence-based prescribing for heavy menstrual bleeding (HMB) can improve quality of life, iron deficiency and anaemia. Tranexamic acid (TXA) is more effective than oral hormonal medications (OHMs). This study aimed to establish temporal trends (2010-23) in TXA prescribing for HMB by Australian general practice registrars.
Method:
Cross-sectional analyses were conducted within an ongoing inception cohort study (Registrar Clinical Encounters in Training [ReCEnT]), using multivariable mixed logistic regression models.
Results:
In 4717 registrars (response rate 93.4%), adjusted odds of prescribing TXA for HMB increased by 12% annually (odds ratio [OR] 1.12, 95% confidence interval [CI]: 1.04-1.20], P=0.004), and 18% annually when compared to OHMs (OR 1.18, 95% CI: 1.03-1.36, P=0.019). General practice registrars who consulted their supervisor were less likely to prescribe TXA compared to OHMs (OR 0.36, 95% CI: 0.14-0.92, P=0.034).
Discussion:
Registrars' increasing TXA prescribing suggests an appropriate response to evidence. Supervisors may be slower to implement this evidence, warranting further investigation to inform evidence-based prescribing strategies.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
