Brief summary

This study aims to assess efficacy and safety outcomes of a telehealth model of abortion care. The study will compare efficacy of this model to usual in-clinic care based on published rates. It will also investigate participant acceptability and feasibility of this model of care.

Detailed description

There are 2 components to the study: 1. A clinical records review on all patients 2. A survey study on a subset of patients who agree to participate. Clinical Records Review: We will examine medical chart data on all patients from partnered telehealth providers to analyze efficacy and safety outcomes for medication abortion. These medical chart data will include medical/pregnancy history and abortion outcome and de-identified apart from date of birth, zip code, and dates of service. Survey Study: Following completion of the telehealth provider's standard medical screening, all patients eligible to receive care through the telehealth provider will be directed to a page providing detailed information about the CHAT Evaluation Study and given the option to participate. Participation in the study involves completing our online questionnaires only. Being in the research study will not affect their care or treatment plan. Declining to participate in our research study will not affect their care. If interested, the patient will provide electronic consent and complete a baseline survey to report socio-demographic characteristics, pregnancy history, and reasons for interest in telehealth medication abortion services. An online follow-up survey will be administered 3-7 days after receiving mifepristone and then once again 4 weeks after taking mifepristone; assessments will include self-report of medication administration, adverse events, and satisfaction. Among those who complete the study surveys, we will investigate the feasibility, time to abortion, efficacy, safety, and acceptability of telehealth provision of mifepristone, measured using a 4-week follow-up though open-ended and closed-ended survey questions. Individuals who opted not to take the medications will be asked a separate set of follow-up questions to collect data related to diversion, to better understand potential risks.

Design outcomes

Primary

MeasureTime frameDescription
The proportion of participants with a successful abortionDocumented resolution of pregnancy, for most patients assessed at 7 daysThe proportion of participants who have a successful abortion defined as complete abortion without continuing pregnancy, need for manual vacuum aspiration or an additional round of treatment to complete the abortion.
The proportion of participants reporting satisfaction with telehealth for abortionDocumented satisfaction measured at approximately 4 weeks follow upThe proportion of participants reporting being satisfied or very satisfied with telehealth for abortion.
The proportion of participants reporting they would use the telehealth option again if neededDocumented at approximately 4 weeks follow upThe proportion of participants reporting they would use the telehealth option again if needed
The total percentage of participants who carried out the study tasks as directed.Documented at the 7 day follow up surveyThe total percentage of participants who carried out the study tasks as directed.

Secondary

MeasureTime frameDescription
The total percentage of participants who experienced a major adverse eventAssessed at the 7 day and 4 week follow up surveys or any unscheduled contacts from participantsMajor adverse events, either reported by the patient or documented through clinical records. Major adverse events will be defined as any abortion requiring blood transfusion, surgery, or hospitalization
