Trial Outcomes & Findings for Immediate Versus Delayed Insertion of the Copper Intrauterine Device (IUD) After Medication Abortion (NCT NCT00737178)

NCT ID: NCT00737178

Last Updated: 2014-09-19

Results Overview

Six months after enrollment, we determined whether or not women were using the IUD through in-person exit interviews and phone interviews. This was an intention to treat analysis, comparing the proportion of women using the IUD based on their group assignment (immediate or delayed).

Participant Flow

Women presenting to Columbia University's Special Gynecology Services for medication abortion will receive comprehensive contraceptive counseling. Those interested in the Intrauterine Device (IUD) for contraception will be offered study participation. Those who accept enrollment in the study and sign consent will be randomized into 1 of 2 groups.

For both groups, the routine 1 week follow-up visit will confirm a successful medication abortion by passage of gestational sac on sonogram. Endometrial stripe thickness will be also be noted. For both groups a transvaginal sonogram will be performed immediately after IUD insertion to confirm IUD position.

SECONDARY outcome

Timeframe: By six months after medication abortion

Insertion rates are the proportion of women in each allocation group (immediate, delayed) who ultimately had the IUD inserted within the 6 month study period.

SECONDARY outcome

Timeframe: Within six months of medication abortion

Population: Per protocol: insertion and removal rates were calculated only for participants undergoing IUD insertion

Expulsion rates were defined as the number of IUDs expelled from the uterus among participants who had the IUD inserted during the study. Removal rates were defined as the number of IUDs that were electively removed by participant request among participants who had the IUD inserted during the study.
