Research on Equity in Abortion Care by TeleHealth

This study will examine the ways in which telehealth for reproductive healthcare affects timing, costs, and follow-up care; whether telehealth reaches people in areas with greater health inequities; and the attributes of telehealth that patients want. Study surveys will be administered to interested, eligible participants: 2,000 patients seeking abortion care will complete the study, comprising of 2 groups: patients seeking medication abortion care either (1) in-person or (2) via telehealth. This project will address how telehealth services can be optimized for people of color, low-income people, and immigrants to increase digital inclusion and health equity.

The Use of Letrozole or Mifepristone for Pretreatment of Medical Termination of Pregnancy

Medical termination of pregnancy (mTOP) generally involves using either a combined regimen consisting of mifepristone and misoprostol, or a misoprostol-only regimen. Complete abortion rates of first trimester mTOP with the use of misoprostol-only regimen varies between 74-88%. With the addition of mifepristone as pre-treatment drug, this improves success rates to 93-97%. Mifepristone, an anti-progesterone, is relatively expensive and is subject to stringent regulations for usage in addition to restricted access in many countries. Therefore, there is a need to find a cheaper and more readily available, yet effective alternative. The use of letrozole (an aromatase inhibitor) in mTOP is postulated to suppress estradiol levels (an important factor in the maintenance of early pregnancy), therefore enhancing the effect of misoprostol in inducing abortion. Studies have shown that pre-treatment with letrozole achieves a complete abortion rate of 77-98%, similar to that in mifepristone-Misoprostol studies. The investigators hypothesise that letrozole is equivalent to mifepristone for the pre-treatment of mTOP and propose to conduct a randomised, non-inferiority trial for mTOP up to 10 weeks gestation with two arms as detailed below: 1. Oral letrozole 10mg daily for 3 days, followed by vaginal misoprostol on Day 3 (Intervention group) 2. Oral mifepristone 200mg once on Day 1, followed by vaginal misoprostol 800mcg on Day 3. Then, 4 hours later, another dose of 400mcg PV misoprostol if no signs of abortion (Control group - current practice). The investigators aim to include a total of 144 patients, 72 in each arm, to detect a non-inferiority margin of 15% with a power of 80% at 5% significance. The investigators primary outcome will be rate of complete abortion by Day 21-28 of mTOP. This pilot RCT will provide preliminary data and preparation for larger grant application which will provide necessary evidence to enhance the care of women undergoing mTOP, with enhanced cost-savings and availability.
