About this study

Official title: Immediate Versus Delayed Initiation of Oral Contraceptive Pills After Therapeutic Abortion - A Randomized Trial

This is a randomized, controlled trial investigating whether immediate versus standard, "Sunday Start", initiation of oral contraceptive pills (OCPs) in post-abortion subjects can improve compliance and the continuation of contraception. Immediate initiation of OCPs has been studied in women seeking contraception when they are not immediately post-abortion, and this "Quick Start" method has been shown to improve the continuation of OCPs into a second pill pack. The primary hypothesis of this study is that immediate initiation of OCPs in post-abortal women will improve the continuation of contraception over delayed initiation on the first Sunday after an abortion.

Read the detailed description

The United States has a higher rate of unintended pregnancy than Canada or any other developed nation in Europe. OCPs are the most common method of hormonal contraception used in this country. Perfect use can lead to failure rates as low as 0.1% per year. Actual failure rates are much higher, often due to non-compliance with OCP use. Several recent studies have examined the "Quick Start", or initiation of OCPs in front of the provider while still at the clinic, regardless of time in the cycle. These studies have shown that women who swallowed the first OCP in the clinic were more likely to continue the OCP into the second month. Women who are seen in clinics for a therapeutic abortion (TAB) are often at extremely high risk for another unintended/unwanted pregnancy. If compliance in OCP use could be improved in this group of women, unintended/unwanted pregnancy rates could be reduced. One concern about the "Quick Start" technique is that women may have already ovulated or conceived when OCPs are initiated mid-cycle. In the post-abortal setting, this is not a concern. Applying the "Quick Start" technique to post-abortion patients and having women take the first of their OCPs while still in the clinic after their abortion may improve compliance and continuation of OCP use.

This is a prospective, randomized, controlled trial in post-abortal women, and will last approximately 24 months. All of the study subjects will receive a single pack of combination OCPs and a one-year prescription after their TAB. The women in the immediate start arm will then take their first OCP in the clinic, observed by clinic staff, before leaving. The controls will be instructed to begin the OCPs on the first Sunday following their abortion. All subjects will receive the same medication with the only difference being the timing of initiation of the OCPs. Measurements of continuation will be determined by telephone interviews administered at two and six months after the subjects' abortion.

Questions about this trial

What is this clinical trial studying?

A study testing Immediate initiation of OCPs and Delayed initiation of OCPs in people with Abortion, run by University of California, San Francisco at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Nov 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Continuation of OCPs after abortion (time frame: Two and six months post-enrollment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Nov 2012.
