Lower unintended pregnancy rates: Use IUD for emergency contraception

Lower unintended pregnancy rates: Use IUD for emergency contraception

Copper-T IUD most effective form of EC, but use remains low

Women seeking emergency contraception (EC) are at high risk of unintended pregnancy. To counter this possibility, family planning providers often issue advance supply of emergency contraceptive pills (ECPs). But is this practice effective in addressing the problem?

Analysis of all available data to date indicates that efficacy of advance provision compared with standard provision of ECPs in reducing unintended pregnancy rates at the population level has not been demonstrated.¹ Data show that while any use of ECPs was two to seven times greater among women who received an advanced supply of pills, there was no significant reduction in unintended pregnancy (relative risk 0.90, 95% confidence interval 0.69-1.18) over 12 months when advance provision was compared with standard provision of ECPs.

The copper-T intrauterine device (ParaGard IUD, Teva Women’s Health, North Wales, PA) is the most effective method of EC with a failure rate of less than 0.1%, yet few family planning providers offer EC IUD insertions. Results of a survey of 1,246 clinicians in a California state family planning program, where contraceptives approved by the Food and Drug Administration are available at no cost to low-income women, show most clinicians (85%) never recommended the copper IUD for emergency contraception, and most (93%) required two or more visits for an IUD insertion.²

Why are providers hesitant when it comes to inserting IUDs for EC? David Turok, MD, associate professor in the University of Utah Department of Obstetrics and Gynecology in Salt Lake City, hears several explanations when he speaks to family planning groups. Providers say their clinics don’t have the financial resources to stock devices, don’t have the time to obtain preapprovals for insertions, or don’t have the flexibility in scheduling time for EC insertions, he says. Such practices need to change, he says.

"We need to have the ability to view these things as true contraceptive emergencies, just like cardiologists and emergency room physicians view chest pain as a cardiac emergency," explains Eleanor Bimla Schwarz, MD, MS, director of the Women’s Health Services Research Unit and associate professor of medicine, epidemiology, and obstetrics, gynecology, and reproductive sciences at the University of Pittsburgh. "In those cases, we’re not telling people come back tomorrow or some other day.’ We see them on the spot, and that’s the shift that we need to make in order to make it happen."

Schwarz and Turok led a session at the recent Reproductive Health 2013 national conference in Denver to optimize chances for women seeking EC to initiate a highly effective method of contraception before leaving the clinic.³ Participants were asked to reflect on challenges that might arise in their own clinical settings when trying to offer emergency IUD placement and to brainstorm potential solutions. The session also focused on helping women who opt for ECPs to transition to other highly effective methods of contraception, such as the contraceptive implant (Nexplanon, Merck & Co., Whitehouse Station, NJ) or the levonorgestrel IUD (Mirena, Bayer HealthCare Pharmaceuticals, Wayne, NJ), before leaving the clinic.

What did Pittsburgh do?

Researchers at the University of Pittsburgh have developed a program to ensure that all women who seek EC or walk in pregnancy (WIP) testing are equipped with the knowledge and services they need to avoid unintended pregnancy.

The researchers explored how often women seeking clinic-based pregnancy testing who don’t desire pregnancy might benefit from EC, as well as examined variables associated with patients asking for EC when use is indicated. They invited women seeking pregnancy testing or EC from a Pittsburgh inner-city Title-X-funded family planning clinic to complete surveys. Twenty-seven percent of women were seeking EC, and 73% were seeking pregnancy testing. Of those seeking pregnancy testing, 39% might have benefited from same-day use of EC pills.

Researchers found that women who had never used EC and who had more than one episode of unprotected sex within the past month were less likely to request EC when use was indicated, while single women were more likely to request EC. Counseling regarding EC options is important for women seeking same-day pregnancy testing who don’t desire pregnancy, researchers conclude.⁴

The Pittsburgh researchers then looked at what it would take for a Title X clinic to routinely offer women seeking EC or WIP same-day placement of highly effective reversible contraception. They also looked at the impact of brief structured counseling about long-acting reversible contraception (LARC), combined with the offer of same-day placement, on women’s knowledge of IUDs and implants and contraceptive use. (See the brief scripted counseling message on this page.)

Of women who came into the Pittsburgh clinic for EC, 29% received an IUD within five days, and 34% had an IUD within three months. These women represent an additional 5% of women who received an IUD more than five days after their EC visit. About 19% of women reported the counseling prompted their switch to an IUD.³

During the baseline period, no women received an IUD on the day of their clinic visit, Schwarz noted. After researchers implemented the brief counseling script, 10.5% of women had an EC IUD inserted.

A total of 95 women came to the clinic for EC and left with levonorgestrel ECPs; seven of those women were pregnant by three months. Ten women who presented for EC left with ulipristal acetate pills; three of them were pregnant by three months. In contrast, none of the women who requested EC and had a copper-T IUD inserted same-day (25 women) were pregnant at three months.³

Look at opportunities

When can a copper-T IUD be placed for EC? According to the recently released U.S. Selected Practice Recommendations for Contraceptive Use, it can be inserted within five days of unprotected intercourse, but can be inserted six or more days after unprotected sex if the day of ovulation can be estimated and not more than five days have passed since ovulation, says Schwarz.⁵

What can be gained from the results of the Pittsburgh project? Schwarz says it is possible for a Title X clinic to routinely inform women about the option of EC IUD. As only 10-20% of women might opt for same-day intrauterine contraception, this practice will not flood most clinic schedules, she notes. Clinics must have IUDs in their stock cabinet prior to establishing same-day EC IUD insertion services, Schwarz says.(To read about Utah clinics’ experience with IUD EC insertions, see the story on p. 136.)
