We would like to find out which time is BEST to place intrauterine contraception (IUC) after an abortion for a pregnancy of 12 weeks or more: either immediately following the abortion or to wait for four weeks (the usual care).

We would like to invite you to take part in this study if you...

  • Are a BC resident registered with the Medical Services Plan health care system;
  • Have given consent to have an abortion for a pregnancy of 12 weeks or more;
  • Have decided to use a Copper Intrauterine Device or Mirena Intrauterine System after the abortion.

Joining this study is simple!

  • You will be asked to sign a consent form and complete a simple questionnaire
  • A computer-based system will randomly decide if you will have your IUC put in right after your abortion or 4 weeks later.
  • You will have your abortion and follow up for the abortion in the normal way
  • We would like to contact you to fill in questionnaires at 3 & 6 months and annually to five years after the abortion.

We will provide you with your chosen IUC at no cost. You will also receive a $20 gift card to reimburse you for your time.

  • Your time and participation are highly valued!
  • Your participation will lead to better understanding of contraceptive choices for women in the future.
  • Please do not hesitate to contact us if you have any questions.
  • No information that discloses your identity will be released or published.
  • Your confidentiality will be respected.

If you are interested in participating in this study, discuss it with the counsellor during your counselling session at the clinic where you have made your appointment and decide whether it is right for you.

*Study results will be published here when available in approximately 2018.

More information about the Better Contraceptive Choices Study

Women can become pregnant almost immediately following an abortion and women having an abortion past 12 weeks are at high risk for having another unwanted pregnancy. The goal of this study is to help women to prevent unwanted pregnancies by improving their access to the contraception they prefer. This can help them to have more control over their own bodies and can help to improve their lives.

Intrauterine contraception (IUC) is one of the best methods of birth control. IUC includes the Copper Intrauterine Device (copper IUD) and the Mirena Intrauterine System (Mirena). Studies have shown it is best to insert IUC immediately after an abortion for a pregnancy less than 12 weeks. For pregnancies over 12 weeks (called “second trimester”) there is not evidence to suggest whether it is best to put in IUC right after an abortion, or to wait 4 weeks. This study aims to find out which time is best to put in a copper IUD or a Mirena after a second trimester abortion.

The study is taking place at several clinics in BC. We will enroll a total of 716 women (350 choosing Mirena and 366 choosing Copper IUD), approximately half of each IUC group will be randomized to get an immediate insertion and the other half will be randomized

to get an interval (4 week) insertion. Being randomized means that there is a fifty-fifty percent chance that you will be assigned to the immediate group or the delayed group. This study began in April 2010 and will be recruiting women for approximately 14 months. All follow up will be finished by 2016. We will compare the pregnancy rate at one through five years between the groups of women who are assigned to have IUC inserted right after their abortion to those who are assigned to have IUC inserted 4-weeks after their abortion.

Participation in this research study is offered to women who (1) are residents of British Columbia, registered with the Medical Services Plan (MSP) health care system; (2) have given consent to have an abortion for a pregnancy of 12 weeks or more and (3) have decided to use IUC after the abortion.
