A Clinical Audit of MTOP Outcomes in a Regional GP Clinic
Abstract Overview
Background:
Recent legislative changes in Western Australia have improved access to medical termination of pregnancy (MTOP) up to 63 days gestation. While MS-2 Step is reported to have high efficacy with minimal failure and complication rates, clinical experience suggests these may be higher than previously expected.
Objective:
To assess MTOP outcomes in a single regional GP clinic for a 12-month period.
Methods:
An audit of MTOP prescriptions issued between 01/01 -30/12/2024 was conducted using Best Practice software. Patient data including age, gestation, BMI, and reproductive history were analysed to identify outcome trends and potential influencing factors.
Results:
Of 101 prescriptions, 61 had follow-up data. There were 50 successful terminations and 11 failures, including 6 requiring D&C. Overall failure rates were 1.5 times higher than literature estimates, with D&C rates up to 2.45 times higher. Greater success rates were observed in patients aged 25–34 and those with BMI ≥30. A small subset with >4 prior terminations had a 100% failure rate.
Conclusion:
MTOP remains a vital medication for women, however this audit suggests it may have a higher than expected rate of failure and post-MTOP intervention in the clinical setting, requiring vigilant and robust follow-up practices for optimal patient outcomes.
