Abortion
Conditions
Brief summary
Patients who seek medication abortion early in pregnancy may have an ultrasound that does not show a pregnancy in the uterus. This is known as a pregnancy of unknown location. These patients most likely have a pregnancy in the uterus that is too early to be seen on ultrasound, but it is possible that the pregnancy is not seen inside the uterus because it is outside of the uterus, known as an ectopic pregnancy. Patients with ectopic pregnancies are at risk for serious complications, and the medications used for medication abortion may not end an ectopic pregnancy. Currently, at Planned Parenthood League of Massachusetts (PPLM), patients seeking medication abortion, including some patients with a pregnancy of unknown location, are given mifepristone to begin the medication abortion at the clinic and then one dose of misoprostol to take at home to cause the pregnancy to pass. However, research suggests that a second dose of misoprostol leads to a higher rate of completed abortion for certain patients. This research is being conducted to learn if two doses of the at-home misoprostol during the medication abortion process leads to a higher rate of completed abortion for patients with pregnancy of unknown location. In this study, all participants will receive mifepristone as they normally would. Then, participants will be randomly assigned to receive either one dose of misoprostol or two doses of misoprostol.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Recruitment rates, to determine feasibility of recruitment | 1 year | Feasibility of recruitment will be assessed by the recruitment and refusal rates. The recruitment rate will be calculated by dividing the total number of participants recruited by the number of months spent for recruitment. |
| Acceptability of second dose of misoprostol | 1 month per subject, 1 year for all subjects | Acceptability of this regimen will be assessed by measuring how often patients assigned to the treatment arm actually take the second dose of misoprostol. If 13 or more patients in the double-miso group (\>50%) do not take the second dose, this will be considered unacceptable. |
| Refusal rates, to determine feasibility of recruitment | 1 year | Feasibility recruitment will be assessed by the recruitment and refusal rates. The refusal rate will be calculated by dividing the total number of participants recruited by the number of patients approached for study participation.. |
