Patterns of emergency contraception use by age and ethnicity from a randomized trial comparing advance provision and information only

One-year pregnancy and continuation rates after placement of levonorgestrel or copper intrauterine devices for emergency contraception: a randomized controlled trial

BACKGROUND

Recent evidence demonstrates the effectiveness of the levonorgestrel 52-mg intrauterine device for emergency contraception vs the copper T380A intrauterine device. Of note, 1-year pregnancy and continuation rates after intrauterine device placement for emergency contraception remain understudied.

OBJECTIVE

This study compared 1-year pregnancy and intrauterine device continuation rates and reasons for discontinuation among emergency contraception users randomized to the levonorgestrel 52-mg intrauterine device or the copper intrauterine device.

STUDY DESIGN

This participant-masked, randomized noninferiority trial recruited emergency contraception individuals desiring an intrauterine device from 6 Utah family planning clinics between August 2016 and December 2019. Participants were randomized 1:1 to the levonorgestrel 52-mg intrauterine device group or the copper T380A intrauterine device group. Treatment allocation was revealed to participants at the 1-month follow-up. Trained personnel followed up the participants by phone, text, or e-mail at 5 time points in 1 year and reviewed electronic health records for pregnancy and intrauterine device continuation outcomes for both confirmation and nonresponders. We assessed the reasons for the discontinuation and used Cox proportional-hazard models, Kaplan-Meier estimates, and log-rank tests to assess differences in the continuation and pregnancy rates between the groups.

RESULTS

The levonorgestrel and copper intrauterine device groups included 327 and 328 participants, respectively, receiving the respective interventions. By intention-to-treat analysis at 1 year, the pregnancy rates were similar between intrauterine device types (2.8% [9/327] in levonorgestrel 52-mg intrauterine device vs 3.0% [10/328] in copper intrauterine device; risk ratio, 0.9; 95% confidence interval, 0.4-2.2; P=.82). Most pregnancies occurred in participants after intrauterine device removal, with only 1 device failure in each group. Of note, 1-year continuation rates did not differ between groups with 204 of 327 levonorgestrel 52-mg intrauterine device users (62.4%) and 183 of 328 copper T380A intrauterine device users (55.8%) continuing intrauterine device use at 1 year (risk ratio, 1.1; 95% confidence interval, 1.0-1.2; P=.09). There were differences concerning the reasons for discontinuation between intrauterine device types, with more bleeding and cramping cited among copper intrauterine device users.

CONCLUSION

The pregnancy rates were low and similar between intrauterine device types. Of note, 6 of 10 intrauterine device emergency contraception users continued use at 1 year. Moreover, 1-year continuation rates were similar between intrauterine device types.

One-year continuation of copper or levonorgestrel intrauterine devices initiated at the time of emergency contraception

OBJECTIVE(S)

This study compares 1-year intrauterine device (IUD) continuation among women presenting for emergency contraception (EC) and initiating the copper (Cu T380A) IUD or the levonorgestrel (LNG) 52 mg IUD plus 1.5 mg oral LNG.

STUDY DESIGN

This cohort study enrolled 188 women who presented at a single family planning clinic in Utah between June 2013 and September 2014 and selected either the Cu T380A IUD or LNG 52 mg IUD plus oral LNG for EC. Trained personnel followed participants by phone, text or e-mail for 12 months or until discontinuation occurred. We assessed reasons for discontinuation and used Cox proportional hazard models, Kaplan-Meier estimates and log-rank tests to assess differences in continuation rates between IUDs.

RESULTS

One hundred seventy-six women received IUDs; 66 (37%) chose the Cu T380A IUD and 110 (63%) chose the LNG 52 mg IUD plus oral LNG. At 1 year, we accounted for 147 (84%) participants, 33 (22%) had requested removals, 13 (9%) had an expulsion and declined reinsertion, 3 (2%) had a pregnancy with their IUD in place and 98 (67%) were still using their device. Continuation rates did not differ by IUD type; 60% of Cu T380A IUD users and 70% of LNG 52 mg IUD plus oral LNG users were still using their device at 12 months (adjusted hazard ratio 0.72, 95% confidence interval 0.40-1.3).

CONCLUSION(S)

Two-thirds of women who chose IUD placement at the EC clinical encounter continued use at 1 year. Women initiating Cu T380A IUD and LNG 52 mg IUD had similar 1-year continuation rates. These findings support same-day insertion of IUDs for women who are seeking EC and would like to use a highly effective reversible method going forward.

IMPLICATIONS

Providing IUD options for EC users presents an opportunity to increase availability of highly effective contraception.

The safety of available and emerging options for emergency contraception

INTRODUCTION

Emergency contraception (EC) is a way to significantly reduce the chance of becoming pregnant after an episode of unprotected intercourse. Considerable data support the safety of all available and emerging options for EC. Areas covered: This review presents a comprehensive summary of the literature regarding the safety of EC as well as directions for further study. PubMed was searched for all relevant studies published prior to June 2017. Expertopinion: All available methods of EC (i.e., ulipristal acetate pills, levonorgestrel pills, and the copper-IUD), carry only mild side effects and serious adverse events are essentially unknown. The copper IUD has the highest efficacy of EC methods. Given the excellent safety profiles of mifepristone and the levonorgestrel IUD, research is ongoing related to use of these products for EC.

Practice Bulletin No. 152: Emergency Contraception

Emergency contraception, also known as postcoital contraception, is therapy used to prevent pregnancy after an unprotected or inadequately protected act of sexual intercourse. Common indications for emergency contraception include contraceptive failure (eg, condom breakage or missed doses of oral contraceptives) and failure to use any form of contraception (). Although oral emergency contraception was first described in the medical literature in the 1960s, the U.S. Food and Drug Administration (FDA) approved the first dedicated product for emergency contraception in 1998. Since then, several new products have been introduced. Methods of emergency contraception include oral administration of combined estrogen-progestin, progestin only, or selective progesterone receptor modulators and insertion of a copper intrauterine device (IUD). Many women are unaware of the existence of emergency contraception, misunderstand its use and safety, or do not use it when a need arises (). The purpose of this Practice Bulletin is to review the evidence for the efficacy and safety of available methods of emergency contraception and to increase awareness of these methods among obstetrician-gynecologists and other gynecologic providers.

Improving access to emergency contraception pills through strengthening service delivery and demand generation: a systematic review of current evidence in low and middle-income countries

OBJECTIVES

Emergency contraception pills (ECP) are among the 13 essential commodities in the framework for action established by the UN Commission on Life-Saving Commodities for Women and Children. Despite having been on the market for nearly 20 years, a number of barriers still limit women's access to ECP in low- and middle-income countries (LMIC) including limited consumer knowledge and poor availability. This paper reports the results of a review to synthesise the current evidence on service delivery strategies to improve access to ECP.

METHODS

A narrative synthesis methodology was used to examine peer reviewed research literature (2003 to 2013) from diverse methodological traditions to provide critical insights into strategies to improve access from a service delivery perspective. The studies were appraised using established scoring systems and the findings of included papers thematically analysed and patterns mapped across all findings using concept mapping.

FINDINGS

Ten papers were included in the review. Despite limited research of adequate quality, promising strategies to improve access were identified including: advance provision of ECP; task shifting and sharing; intersectoral collaboration for sexual assault; m-health for information provision; and scale up through national family planning programs.

CONCLUSION

There are a number of gaps in the research concerning service delivery and ECP in LMIC. These include a lack of knowledge concerning private/commercial sector contributions to improving access, the needs of vulnerable groups of women, approaches to enhancing intersectoral collaboration, evidence for social marketing models and investment cases for ECP.

We should really keep in touch: predictors of the ability to maintain contact with contraception clinical trial participants over 12 months

OBJECTIVES

This study assesses the ability to maintain contact with participants enrolled in an emergency contraception (EC) trial with 12 months of follow-up based on the modes of contact they provided at enrollment.

STUDY DESIGN

Data came from a clinical trial offering women the copper intrauterine device or oral levonorgestrel for EC. A modified Poisson regression was used to assess predictors associated with the ability to contact study participants 12 months after enrollment.

RESULTS

Data were available for 542 participants; 443 (82%) could be contacted at 12 months. Contact at 12 months was greatest for those whose preferred the method of contact was text messaging, e-mail or any (62/68; 91% contacted) and worst for the 18 who had a landline phone (only 7 contacted; 39%). After controlling for age, having an e-mail address, text messaging, language preference, type of EC chosen and insurance, preferred contact other than phone increased the likelihood of follow-up by 10% [risk ratio (RR) 1.1 95% confidence interval (CI) 1.0-1.2], while having a landline reduced a woman's likelihood of being contacted at 12 months by 50% compared to women with a contract cell (RR 0.5, 95% CI 0.3-1.0).

CONCLUSION

The few women with a landline for contact had poor follow-up at 1 year, while women who preferred e-mail or text had the highest rate of follow-up.

IMPLICATIONS

Understanding how best to reduce loss to follow-up is an essential component of conducting a contraceptive clinical trial. Improved participant retention maximizes internal validity and allows for important clinical outcomes, such as pregnancy, to be assessed.

Emergency contraception with a copper IUD or oral levonorgestrel: an observational study of 1-year pregnancy rates

OBJECTIVE

We investigated the 1-year pregnancy rates for emergency contraception (EC) users who selected the copper T380 intrauterine device (IUD) or oral levonorgestrel (LNG) for EC.

STUDY DESIGN

This prospective study followed women for 1 year after choosing either the copper T380 IUD or oral LNG for EC. The study was powered to detect a 6% difference in pregnancy rates within the year after presenting for EC.

RESULTS

Of the 542 women who presented for EC, agreed to participate in the trial and met the inclusion criteria, 215 (40%) chose the copper IUD and 327 (60%) chose oral LNG. In the IUD group, 127 (59%) were nulligravid. IUD insertion failed in 42 women (19%). The 1-year follow-up rate was 443/542 (82%); 64% of IUD users contacted at 1 year still had their IUDs in place. The 1-year cumulative pregnancy rate in women choosing the IUD was 6.5% vs. 12.2% in those choosing oral LNG [hazard ratio (HR) 0.53, 95% confidence interval (CI): 0.29-0.97, p=.041]. By type of EC method actually received, corresponding values were 5.2% for copper IUD users vs. 12.3% for oral LNG users (HR 0.42, 95% CI: 0.20-0.85, p=.017). A multivariable logistic regression model controlling for demographic variables demonstrates that women who chose the IUD for EC had fewer pregnancies in the following year than those who chose oral LNG (HR 0.50, 95% CI: 0.26-0.96, p=.037).

CONCLUSION

One year after presenting for EC, women choosing the copper IUD for EC were half as likely to have a pregnancy compared to those choosing oral LNG.

IMPLICATIONS

Compared to EC users who choose oral levonorgestrel, those who select the copper IUD have lower rates of pregnancy in the next year. Greater use of the copper IUD for EC may lower rates of unintended pregnancy in high-risk women.

Knowledge, attitude, and practice about Emergency Contraception among health staff in Bushehr state, south of Iran

Emergency Contraception (EC) is used within a few days of unprotected sex to prevent an unintended pregnancy. About one quarter of pregnancies in south of Iran are unintended. EC is important option that women can use after unprotected sex or contraceptive failure for preventing of unplanned pregnancies and adverse maternal and perinatal health outcomes. Health staff have influence on women’s contraceptive behavior and their knowledge and attitudes about EC can affect women’s contraceptive behaviors. Data are lacking about the knowledge, attitude and practice of hormonal EC method among health staff in Bushehr state, south of Iran. A cross-sectional study using self administered questionnaire was conducted. A sample of 170 health staff were surveyed. The mean age of respondents was 30.6±5.1. Overall 6.5% of participants had poor knowledge, 25.2% moderate knowledge, 68.3% good knowledge about EC. Half of participants had positive and half had negative attitude towards the EC method. Midwives and family health workers were more knowledgeable (p<0.05) and more frequently counseled women about EC than general practitioners (GPs) (p<0.001). The most cited reason for EC prescriptions were rupture condom and none use of contraception. Our findings showed despite of majority of health staff had good knowledge about EC, their knowledge about the indications for prescription of EC and its side effects was inadequate. The educational efforts for health staff should be focused more on the specific aspects of EC method. GPs also should be more involved in family planning program.

The copper intrauterine device for emergency contraception: an opportunity to provide the optimal emergency contraception method and transition to highly effective contraception

Worldwide, 40% of all pregnancies are unintended. Widespread, over-the-counter availability of oral emergency contraception (EC) has not reduced unintended pregnancy rates. The EC visit presents an opportunity to initiate a highly effective method of contraception in a population at high risk of unintended pregnancy who are actively seeking to avoid pregnancy. The copper intrauterine device (IUD), the most effective method of EC, continues to provide contraception as effective as sterilization for up to 12 years, and it should be offered as the first-line method of EC wherever possible. Increased demand for and supply of the copper IUD for EC may have an important role in reducing rates of unintended pregnancy. The EC visit should include access to the copper IUD as optimal care but should ideally include access to all highly effective methods of contraception.

Advance supply of emergency contraception: a systematic review

BACKGROUND

Emergency contraceptive pills (ECPs) are an underutilized means to reduce unintended pregnancy. Advance provision of ECPs may increase timely use, thereby decreasing risk of unintended pregnancy.

STUDY DESIGN

We searched MEDLINE and EMBASE through February 2012 for randomized, controlled trials (RCTs) pertaining to safety and efficacy of advance provision of ECP. The quality of each individual study was evaluated using the United States Preventive Services Task Force evidence grading system.

RESULTS

The search strategy identified 714 articles. Seventeen papers reported on safety or efficacy of advance ECPs in adult or adolescent women. Any use of ECPs was two to seven times greater among women who received an advanced supply of ECP. However, a summary estimate (RR 0.90, 95% CI 0.69-1.18) of four RCTs did not demonstrate a significant reduction in unintended pregnancy over 12 months when advance provision was compared with standard provision of ECPs. Patterns of contraceptive use, pregnancy rates and incidence of sexually transmitted infections did not vary between treatment and control groups in the majority of studies among either adults or adolescents.

CONCLUSION

Available evidence supports the safety of advance provision of ECPs. Efficacy of advance provision compared with standard provision of ECPs in reducing unintended pregnancy rates at the population level has not been demonstrated.

Emergency contraception and risk for sexually transmitted infections among U.S. women

BACKGROUND

Since Food and Drug Administration (FDA) licensure of emergency contraception (EC) over-the-counter (OTC) in 2006, this is the first U.S. study to use a nationally representative sample of reproductive-aged women (15-44) to explore the relationship between receipt and use of EC and sexually transmitted infection (STI)-related health services.

METHODS

Using a sample of 6329 women from the National Survey of Family Growth 2006-2008, we examined the relationship between lifetime EC use and recent receipt of EC and demographics, sexual behaviors, and STI-related services. Variables significant at p<0.10 in bivariate analyses were examined using multivariable logistic regression models.

RESULTS

Overall, 10% (704) of the sample had ever used EC. Most EC users had received EC from a family planning clinic (51%), drugstore (23%), or doctor's office (17%). In adjusted analyses, demographic factors associated with receipt of EC in the past 12 months included never married (adjusted odds ratio [AOR] 4.0) and living in a metropolitan statistical area (AOR 4.2). Women reporting multiple partners (2+) (AOR 2.4), inconsistent condom use (AOR 3.4), and having recently been tested for chlamydia (AOR 2.0) had higher odds of receiving EC in the past 12 months. Findings among women ever reporting EC use were similar, except women who had 4+ lifetime partners (AOR 2.5) and had recently received a chlamydia diagnosis (AOR 2.2) had higher odds of ever having used EC.

CONCLUSIONS

EC recipients were no more likely than nonrecipients to have received STI counseling or screening despite greater numbers of sex partners in the past year. This research indicates that women are accessing EC in pharmacies, which may be a missed opportunity for counseling and testing.

Use of levonorgestrel emergency contraception in Utah: is it more than "plan B"?

CONTEXT

It is important to understand why some women use levonorgestrel emergency contraceptive pills repeatedly, because the method is not intended for repeated use, and current evidence suggests that it is approximately 77% effective at preventing pregnancy.

METHODS

An anonymous patient survey of 1,040 women aged 18-29 purchasing levonorgestrel at Planned Parenthood clinics in Utah was conducted during a 4-6-week period in 2007. Chi-square tests and analyses of variance were used to examine associations between selected characteristics and level of levonorgestrel use. Logistic regression was used to assess characteristics independently associated with repeated use.

RESULTS

Twenty-nine percent of participants had used levonorgestrel more than twice in the prior year. Fifty-eight percent believed that levonorgestrel is at least 90% effective in protecting against pregnancy; 16% believed that it is 100% effective. In univariate analyses, lifetime number of partners, currently having multiple partners, substance use at last intercourse and perceived effectiveness of levonorgestrel were positively associated with repeated levonorgestrel use in the previous year. The measure most strongly associated with repeated levonorgestrel use in multivariate analyses was perceived effectiveness: Women who believed that the method is 90-99% or 100% effective in preventing pregnancy had greater odds of repeated use than those who believed it is 75-89% effective (odds ratios, 1.8 each).

CONCLUSION

Women who repeatedly use levonorgestrel may have an inflated perception of its effectiveness. Future research, including qualitative research, may help clarify factors that lead to inflated perceptions of effectiveness.

Provision of emergency contraception at student health centers in California community colleges

BACKGROUND

Approximately half of all pregnancies in the United States are unintended, with the highest rates reported among college-age women. The availability of emergency contraception (EC) pills can be an important component of efforts to reduce unintended pregnancy. Student health centers at community colleges can uniquely support student retention and academic achievement among college students by making EC available to reduce the rate of unintended pregnancy and prevent college drop-out. This article highlights findings from an assessment of EC provision in student health centers within the California community college system (n = 73).

METHODS

A web-based survey was used to explore the provision of EC, challenges and barriers of EC administration, promotion of EC availability, and attitudes toward EC.

FINDINGS

Descriptive statistics conducted revealed that more than 6 out of 10 (62%) student health centers provided EC, 77% of which dispense EC on site during clinic visits. The most common EC promotion methods were providing brochures at the health center (80%) and through information provided at family planning or primary care visits (73%). Challenges to EC administration included a perceived lack of awareness of EC among students (71%), followed by the notion that some students may overutilize EC (40%). Attitudes toward EC provision were more favorable among health center staff whose campuses offered EC than those who did not (p < .05).

CONCLUSION

This article provides recommendations for community college health centers to improve access and delivery of EC by addressing issues such as cost and offering more novel EC promotion methods.

Do women and men consider abortion as an alternative to contraception in the United States? An exploratory study

The USA, a country with widespread access to the full range of modern methods of contraception, continues to have one of the highest abortion rates among developed countries. Forty-nine per cent of women reported ever experiencing an unintended pregnancy in 2001; 48% of these conceptions occurred during a month that contraception was used. We explored the extent to which people use contraception and abortion interchangeably to achieve their fertility goals via focus groups (n = 4) and semi-structured in-depth interviews (IDIs) (n = 18) with men and women between the ages of 18 and 35 in New York City in 2006. While there was a consensus that abortion cannot replace contraceptive use, poor couple communication, lack of planning, lack of acceptable contraceptive methods and the pleasures that people associate with having unprotected sex result in the perception that some individuals rely on abortion over contraception to prevent unintended births. Men and women both identified women as solely in charge of avoiding an unwanted pregnancy and resolving it should one occur. No one supported repeat abortions for themselves or others, and many respondents perceived multiple abortions to lead to infertility, which strengthens their position that substituting abortion for contraception is unacceptable.

Attitudes towards family planning among women seeking induced abortion in Izmir, Turkey

OBJECTIVES

To assess contraceptive knowledge, use of emergency contraception (EC) and the motives of women seeking induced abortion.

METHODS

A descriptive and cross-sectional study conducted at the T. C. Izmir Dr. Hayri Ekrem Ustundag Gynaecology and Maternity Hospital and the Izmir Ataturk Research and Teaching Hospital, Turkey. The research sample consisted of 440 women who requested an abortion between January and May 2010, and voluntarily agreed to participate.

RESULTS

Sixty-two percent of the women became pregnant while using family planning (FP) methods. The contraceptive used by 42% was the condom, and 45% believed that they had become pregnant because of improper use of the contraceptive. Ninety-three percent had never used EC. Thirty-seven percent wanted their pregnancy terminated because they did not want another child, whereas 26% viewed induced abortion as a method of FP. Sixty-nine percent of the women received FP counselling from health professionals, and 80% found the information provided adequate.

CONCLUSION

The women assessed were insufficiently knowledgeable about FP in general and EC in particular. Many had become pregnant as a result of inaccurate information.

Should providers give women advance provision of emergency contraceptive pills? A cost-effectiveness analysis

PURPOSE

We sought to determine the potential effect and cost-effectiveness of different means of accessing emergency contraceptive pills (ECP) on unintended pregnancy rates in sexually active women.

METHODS

We used a computer simulation model to compare the effects of advance provision, on-demand provision, and no use of ECP on unintended pregnancies and costs of care in three hypothetical cohorts of 1 million sexually active women. Data on effectiveness of ECP from the single-use clinical trials, and costs from Medi-Cal, California's Medicaid program were used for the model.

FINDINGS

Advance provision of ECP is projected to avert a greater or the same percentage of unintended pregnancies compared with on-demand provision, with the greatest percentage of pregnancies averted (66%) in low-risk women with advance provision. In the simulation model, the percentage of pregnancies averted decreases as the frequency of unprotected intercourse increases and ECP use decreases. In all scenarios, the cost-savings ratio--the number of dollars saved on averted pregnancy expenditures for each dollar spent on advance ECP--is greater than one.

CONCLUSION

Advance provision of ECP has the potential to avert unintended pregnancies and reduce medical expenditures. The most likely reason that the advance provision trials fail to demonstrate reductions in pregnancy rates is a result of a combination of small study sizes, the use of ECP in both treatment and control groups, and a failure to take into account a realistic range of rates of unprotected intercourse and imperfect ECP use.

Advance provision of emergency contraception among adolescent and young adult women: a systematic review of literature

OBJECTIVE

The purpose of this review is to summarize the findings of randomized controlled trials assessing the advance provision of emergency contraception (EC) to women 24 years of age or younger.

DESIGN

We conducted a comprehensive search of the PubMed database from 1950 to November 11, 2009. This review includes seven studies that randomly assigned women aged 24 and younger to advance provision of EC or a control group.

RESULTS

All studies reviewed found that women assigned to advance provision were more likely to use EC, though not all reached statistical significance. Furthermore, studies assessing time to EC use (N = 4) found that those with advance provision used EC sooner following intercourse. Most studies found that women assigned to advance provision of EC did not engage in more sexual risk taking behaviors (assessed by reported number of sexual partners, number of episodes of unprotected intercourse, and acquisition of sexually transmitted infections) or switch to less reliable contraceptive methods. Despite increased use and decreased time to use, women who were provided EC in advance did not report significantly lower pregnancy rates.

CONCLUSIONS

The existing literature suggests that among women 24 years of age or younger, advance provision has a positive impact on use and time to use of EC. Most findings indicate that increased use of EC does not have significant negative effects for ongoing contraceptive use or sexual risk taking behaviors. Despite increased use, advanced provision of EC has not been associated with a significant corresponding decrease in pregnancy.

Adolescent and young adult women's use of emergency contraception

STUDY OBJECTIVE

To determine differences in the use of emergency contraception (EC) between adolescent (11-17 years old) and young adult women (18-24 years old) in an insured, population based cohort.

DESIGN AND PARTICIPANTS

Females 11-24 years old were divided into two groups: adolescents (11-17) and young adults (18-24) at their first captured EC prescription fill. A medical record review followed.

MAIN OUTCOME MEASURES

The main outcomes of our study were reason for EC use, timing of EC use, and repeat use. Chi-square tests were used to compare dichotomous variables between groups by age and for ever vs repeat use. An independent t-test was used to compare continuous variables. A person-time analysis was used to compare rates of repeat use.

RESULTS

344 women were identified as having filled at least one prescription for an EC drug. Among ever users, adolescents were more likely than young adults to cite no contraception as their reason for seeking EC (30% for 11-17 and 24% for 18-24 year olds; P = 0.38). For both ever and repeat users, young adults reported condom failure as their main reason for seeking EC. We calculated t-tests on the hours since unprotected sex. For adolescents the mean was 42 hours and for young adults the mean was 34 hours (P = 0.13). Both are within the recommended 72-hour window for administration and were not significantly different. The rate of repeat use was essentially the same for both age groups.

CONCLUSIONS

We found that adolescent use of EC was similar to young adult use and support the recommendation that 17-year-olds have behind-the-counter access to EC.

A survey of women obtaining emergency contraception: are they interested in using the copper IUD?

BACKGROUND

This study aims to determine if women presenting for emergency contraception (EC) at family planning clinics may be interested in using the copper intrauterine device (IUD) for EC.

STUDY DESIGN

This convenience sample survey was offered to women who presented for EC at four participating clinics in urban Utah. Anonymous written questionnaires were distributed. The outcome variable of interest was interest in using the copper IUD for EC.

RESULTS

Of survey respondents, 320 (34.0%) of 941 said they would be interested in an EC method that was long term, highly effective and reversible. Interested women were not significantly different from noninterested women in relation to age, marital status, education, household income, gravidity, previous abortions, previous sexually transmitted infections (STIs) or relationship status. One hundred twenty women (37.5% of those interested or 12.8% of all those surveyed) would wait an hour, undergo a pelvic exam to get the method and would still want the method knowing it was an IUD. However, only 12.3% of these women could also pay $350 or more for the device. Multivariable regression found the following predictors of interest in the IUD among EC users: non-Hispanic minorities (OR=2.12, 95% CI=1.14-3.93), desire to never be pregnant in the future (OR=2.87, 95% CI=1.38-5.66) and interest in adoption (OR=1.96, 95% CI=1.00-5.73) or abortion (OR=2.68, 95% CI=1.24-4.14) if pregnant when presenting for EC.

CONCLUSION

While one third of EC users surveyed at family planning clinics were interested in a long-term, highly effective method of contraception, only a small portion of all EC users may be interested in the copper IUD for EC. Cost is a potential barrier.

Advance provision of emergency contraception for adolescents

Emergency contraception is most effective at preventing unintended pregnancy when taken as early as possible following unprotected sexual intercourse. Advance provision of this medication supports more timely and effective use. In the midst of rising teen pregnancy rates, current policies often limit access to emergency contraception for adolescents. A literature search identified three recent experimental studies of advance provision for adolescents. This article reviews those studies and finds strong support for advance provision for adolescents. Usage of emergency contraception increased with advance provision and there was no increase in negative sexual behaviors or decrease in usage of other contraceptive forms. Implications of these findings for school nurses and school-based health center staff are also discussed.

[General practitioners' (GPs) practice regarding the line to take in case of missed pill]

OBJECTIVE

To explore general practitioners' (GPs) practice face of missed pill and prevention of such missings.

MATERIAL AND METHOD

Twenty-five GPs from Sarthe Department (Western France) took part in semistructured interview during which they expressed themselves on the prevention of missed pill and its consequences.

RESULTS

Twelve out of 20 physicians stated positively that their female patients often forget their pill. However, they noted that missed pill was seldom a reason for phone call or consultation. During the initial pill prescription, GPs insisted on how to take the pill (14/25) as well as advice in case of a missed pill (22/25), their availability (12/25) and the instruction leaflet (16/25). But only five quoted the importance of involving women in the choice of contraception. On prescription renewal, only nine out of 25 ask their patients about observance defect and eight out of 25 repeated the information. If patients asked for further explanation, only two doctors out of 25 had practices in line with the French National Authority for Health's (HAS) recommandation guidelines.

CONCLUSION

GPs' attitudes are partly due to a lack of practice's knowledge in primary and emergency contraception methods. It seems essential to promote GPs' training and to take into account their expectations and needs. Furthermore, female patient must be actor of the choice of her contraceptive method in order to improve compliance and, therefore, effectiveness.

Emergency contraceptive use as a marker of future risky sex, pregnancy, and sexually transmitted infection

OBJECTIVE

The objective of the study was to examine whether emergency contraceptive use predicts future sex at risk for pregnancy, pregnancy, or sexually transmitted infection among young women.

STUDY DESIGN

A secondary analysis of control group participants (n = 718) from a recent trial of advanced provision of emergency contraception was conducted.

RESULTS

We found no association between use of emergency contraception and either pregnancy or infection. Recent use predicted decreased occurrence of subsequent sex at risk for pregnancy among women with a history of sexually transmitted infection (relative risk [RR], 0.39; 95% confidence interval [CI], 0.15-0.97), whereas ever having used predicted increased occurrence among women who either were highly effective method users (RR, 1.45; 95% CI, 1.05-2.01) or had no history of sexually transmitted infection (RR, 1.31; 95% CI, 1.04-1.65).

CONCLUSION

Information about prior emergency contraceptive use was not a useful predictor of subsequent pregnancy, infection, or sex at risk for pregnancy among these young women.

Increased access to emergency contraception: why it may fail

BACKGROUND

To explore why increased access to emergency contraception (EC) failed to reduce pregnancies in a recent randomized controlled trial.

METHODS

We used multivariable logistic regression to identify risk factors for unintended pregnancy using data from a trial involving sexually active women (n = 1490, aged 14-24 years) randomly assigned to either increased access or standard access to EC. We used predictive modeling to generate estimated pregnancy risk scores for each participant. We then examined EC use among women at low or high baseline risk of pregnancy.

RESULTS

Gravidity, recent history of unprotected sex (within 14 days of enrollment to study) and lower aversion to pregnancy predicted unintended pregnancy. Women in the increased access group were more likely than women in the standard access group to use EC repeatedly. This difference was significantly stronger (P = 0.03) among low risk women than high risk women [Relative risk (RR) 10.0, 95% confidence interval (CI) 6.5-15.4 and RR 5.5, 95% CI 3.8-7.9, respectively].

CONCLUSIONS

Increased access to EC had a greater impact on women who were at lower baseline risk of pregnancy. This may explain in part why increased access to EC has had no measurable benefit in clinical trials.

Implementing an advance emergency contraception policy: what happens in the real world?

CONTEXT

Advance provision of emergency contraception increases the likelihood of its use, yet little is known about the factors that influence successful implementation of an advance provision policy in publicly funded family planning clinics.

METHODS

Data on knowledge of, attitudes toward and use of emergency contraception were collected from 211 patients attending four Title X-funded clinics in Pennsylvania in 2001-2002. In addition, 22 staff from the four clinics were interviewed regarding barriers to and facilitators of advance provision in 2004-2005, and 111 staff from 46 clinics completed related surveys in 2005. Qualitative data underwent content analysis, and frequencies and bivariate associations between variables were calculated for the survey data.

RESULTS

Most patients said they would use emergency contraception (80%) and believed it should be easy to obtain (93%), although 46% thought it is a form of abortion. Patients' familiarity with the method, attitudes toward it and self-efficacy regarding its use were not associated with most demographic or reproductive health characteristics. While nearly all interviewed staff endorsed routine advance provision, only about half of survey respondents offered it "very often" at patients' initial or annual visits. Barriers to advance provision included staff prejudgment of patients' needs and ability to use the method, time constraints and inefficiencies in clinic procedures.

CONCLUSIONS

Strategies that may facilitate advance provision of emergency contraception include emphasizing the need for staff to offer it during all patient visits, providing patient-friendly information and streamlining clinic procedures.

Controversies in contraception

PURPOSE OF REVIEW

New research is constantly being published regarding hormonal contraceptives and bone health, migraine headaches, thrombosis risk, hypertension, weight gain, and obesity, as well as emergency contraception. At times, these studies can be clarifying, but they can also raise new controversies and questions. It is important for providers to be aware of the emerging issues regarding contraceptive care for adolescent patients.

RECENT FINDINGS

Research suggests that Depo-Provera (depot medroxyprogesterone acetate; Pfizer, New York City, New York, USA) and, perhaps, low-dose oral contraceptive pills can have adverse effects on adolescent bone health, although the data demonstrating reversibility of bone loss after discontinuation of these contraceptives are reassuring. Additionally, estrogen-containing contraceptives pose risks for patients, including the onset of or exacerbation of migraine headaches, venous thromboembolism, and hypertension. Depo-Provera has been implicated in weight gain, especially in girls who are already overweight. Obesity may decrease the efficacy of some hormonal contraceptives. Finally, the mechanism of action of emergency contraception is still unknown, although studies continue to suggest that it has primarily preovulatory, not postovulatory, effects.

SUMMARY

Adolescent health providers need to be aware of the new research and controversies in contraceptive care in order to counsel and care for patients effectively.

The impact of programs to increase contraceptive use among adult women: a review of experimental and quasi-experimental studies

CONTEXT

Because rates of unintended pregnancy, abortion and unintended birth are very high among adult women in the United States, it is important to identify interventions that can increase contraceptive use in this population.

METHODS

PubMed, PsycINFO and POPLINE were searched for experimental or quasi-experimental studies published between 1990 and 2005 that evaluated policies or programs designed to increase contraceptive use or reduce pregnancy among adult women in the United States. In addition, relevant journals were searched, experts were asked to provide further citations and several subsequently published articles were included.

RESULTS

Only 11 studies that assessed programs, and none that assessed policies, were found. The evaluated interventions offered pregnancy and STD prevention counseling (one study); provided contraceptives in settings other than family planning clinics (two studies); had women initiate contraceptive use during the medical visit (two studies); provided advance supplies of emergency contraception (four studies); or implemented systems to remind injectable contraceptive users about their next injection (two studies). The interventions generally had positive, albeit short-term, effects on contraceptive use; none reduced pregnancy rates. Programs that gave women a contraceptive during the visit were the most effective at increasing method use. Advance provision of emergency contraception increased the likelihood of its use and did not affect regular contraceptive use.

CONCLUSIONS

Very few studies have evaluated interventions to increase contraceptive use among adult women. A research plan that rigorously assesses the impact of different approaches to increasing contraceptive use among adult women should be an integral part of any long-term effort to prevent unintended pregnancy in the United States.

Characteristics associated with emergency contraception use by family planning patients: a prospective cohort study

CONTEXT

Little is known about how written family planning clinic policy regarding emergency contraception, as well as personal characteristics, behaviors and attitudes, may influence a woman to use emergency contraception.

METHODS

Between June 2001 and July 2002, women attending publicly funded family planning clinics in Pennsylvania were enrolled in an 18-month longitudinal study. Half attended clinics with a policy of offering emergency contraception in advance; the remainder had only emergent access to the drug. After providing baseline data, women completed monthly automated phone surveys about recent sexual activity, contraceptive use and attitudes toward pregnancy. Characteristics associated with recent use of emergency contraception were examined using multivariate logistic regression.

RESULTS

Responses to 3,700 phone surveys from 729 women showed that 25% of those who attended clinics offering advance access used emergency contraception at least once during the study, compared with 8% who attended emergent access clinics. Women attending advance access clinics had significantly elevated odds of having used emergency contraception in the past month (odds ratio, 2.6). Other characteristics positively associated with the likelihood of recent emergency contraception use were familiarity with the drug, having a new sex partner and having unprotected sex at least once (2.0 each); negative feelings toward pregnancy (1.4); and using condoms as one's main contraceptive method (1.8).

CONCLUSIONS

In addition to discussing and offering advance emergency contraception, providers should further explore specific behaviors and attitudes associated with emergency contraception use.

Advance provision of emergency contraception for pregnancy prevention (full review)

BACKGROUND

Emergency contraception can prevent pregnancy when taken after unprotected intercourse. Obtaining emergency contraception within the recommended time frame is difficult for many women. Advance provision, in which women receive a supply of emergency contraception before unprotected sex, could circumvent some obstacles to timely use.

OBJECTIVES

To summarize randomized controlled trials evaluating advance provision of emergency contraception to explore effects on pregnancy rates, sexually transmitted infections, and sexual and contraceptive behaviors.

SEARCH STRATEGY

In August 2006, we searched CENTRAL, EMBASE, POPLINE, MEDLINE via PubMed, and a specialized emergency contraception article database. We also searched reference lists and contacted experts to identify additional published or unpublished trials.

SELECTION CRITERIA

We included randomized controlled trials comparing advance provision and standard access, which was defined as any of the following: counseling which may or may not have included information about emergency contraception, or provision of emergency contraception on request at a clinic or pharmacy.

DATA COLLECTION AND ANALYSIS

We evaluated all identified titles and abstracts found for potential inclusion. Two reviewers independently abstracted data and assessed study quality. We entered and analyzed data using RevMan 4.2.8. We calculated odds ratios with 95% confidence intervals for dichotomous data and weighted mean differences with 95% confidence intervals for continuous data.

MAIN RESULTS

Eight randomized controlled trials met our criteria for inclusion, representing 6389 patients in the United States, China and India. Advance provision did not decrease pregnancy rates (OR 1.0; 95% CI: 0.78 to 1.29 in studies for which we included twelve month follow-up data; OR 0.91; 95% CI: 0.69 to 1.19 in studies for which we included six month follow-up data; OR 0.49; 95% CI: 0.09 to 2.74 in a study with three month follow up data), despite increased use (single use: OR 2.52; 95% CI 1.72 to 3.70; multiple use: OR 4.13; 95% CI 1.77 to 9.63) and faster use (weighted mean difference (WMD) -14.6 hours; 95% CI -16.77 to -12.4 hours). Advance provision did not lead to increased rates of sexually transmitted infections (OR 0.99; 95% CI 0.73 to 1.34), increased frequency of unprotected intercourse, nor changes in contraceptive methods. Women who received emergency contraception in advance were equally as likely to use condoms as other women.

AUTHORS' CONCLUSIONS

Advance provision of emergency contraception did not reduce pregnancy rates when compared to conventional provision. Advance provision does not negatively impact sexual and reproductive health behaviors and outcomes. Women should have easy access to emergency contraception, because it can decrease the chance of pregnancy. However, the interventions tested thus far have not reduced overall pregnancy rates in the populations studied.

Use of emergency contraceptive pills and condoms by college students: a survey

OBJECTIVES

This study examined the intentions, knowledge, and attitudes of college students regarding the use of emergency contraceptive pills (ECPs) and condoms.

DESIGN AND SETTING

A cross-sectional descriptive study was conducted at 16 Korean colleges.

METHODS

Data were collected from March 15 to June 10, 2006 from a convenience sample of 1046 college students using a survey questionnaire. The survey included measures of demographic variables, intention to use ECPs (one item) and condoms (one item), knowledge about ECPs (12 items), and attitudes toward using ECPs (12 items) and condoms (16 items). All items except knowledge were rated on a 5-point Likert-type response format, with higher scores indicating greater intentions, more positive attitudes, and greater knowledge.

RESULTS

Of the 1046 participants, 76.3% had heard of ECPs and 13.2% of the sexually active participants (n=190) had used them. Participants showed a general lack of knowledge about ECPs and misconceptions about their safety. The intentions of using ECPs and condoms were positively correlated with each other and with attitude such that the more positive the attitude, the greater their intention to use both ECPs and condoms. There were significant gender differences on many of the variables, in that female students had higher knowledge about ECPs, intention of using ECPs and condoms, and more positive attitude toward condoms than male students who had more positive attitudes toward ECPs. Females had more concerns about the safety of ECPs than males.

CONCLUSIONS

The findings suggest that college students must be better informed about ECPs, and reassured about their safety. Additionally, promoting ECPs would not negatively affect condom use. Efforts are needed to disseminate up-to-date information to the general public and to develop educational and awareness programs to empower young people to make informed decisions about the use of ECPs and condoms.

Population Effect of Increased Access to Emergency Contraceptive Pills

OBJECTIVE

We systematically reviewed data on effects of increased access to emergency contraceptive pills on pregnancy rates and use of the pills.

DATA SOURCES

We searched MEDLINE, POPLINE, EMBASE, and LILACS, and we consulted with experts.

METHODS OF STUDY SELECTION

We included studies that compared the effect of different levels of access to emergency contraceptive pills on pregnancy rates, use of the pills, and other outcomes.

TABULATION, INTEGRATION, AND RESULTS

Of the 717 articles identified, we selected 23 for review. The studies included randomized trials, cohort studies, and evaluations of community interventions. The quality of these studies varied. In all but one study, increased access to emergency contraceptive pills was associated with greater use. However, no study found an effect on pregnancy or abortion rates.

CONCLUSION

Increased access to emergency contraceptive pills enhances use but has not been shown to reduce unintended pregnancy rates. Further research is needed to explain this finding and to define the best ways to use emergency contraception to produce a public health benefit.
