Emergency Contraception

Emergency contraception - A narrative review of literature

BACKGROUND

Emergency contraception includes several methods of contraception that can be used after unprotected sexual intercourse, after failure of any used method of contraception or in case of sexual abuse, to prevent pregnancy.

PURPOSE OF THE STUDY

The aim of the study was to analyze the available methods of emergency contraception, their mechanisms of action, efficacy, forms of administration, clinical applications and possible adverse effects.

MATERIAL AND METHOD

PubMed, Scopus and Cochrane datebases were searched for articles from 2010 to 2024 about emergency contraception.

RESULTS

The analyzed types of emergency contraception included single oral dose of ulipristal acetate, single oral dose of levonorgestrel and intrauterine system releasing levonorgestrel or copper intrauterine device. Taking emergency contraception in the optimum time according to the drug characteristics allows for avoiding pregnancy in more than 90% of cases (depending on the type of emergency contraception and time from unprotected intercourse). The analyzed literature shows that intrauterine copper intrauterine device is the most effective method of emergency contraception, also together with intrauterine system releasing levonorgestrel leading to the lowest rate of adverse effects.

CONCLUSIONS

Taking emergency contraception can result in various adverse effects, therefore it should be introduced after thorough analysis of woman's medical history, including gynecological and obstetric history and potential contraindications. Additionally, the patient should receive detailed information about the drug mechanism of efficacy and potential adverse effects.

Confidentiality in the Care of Adolescents: Policy Statement

Confidentiality is an essential component of high-quality health care for adolescents and young adults and can have an impact on the health care experiences and health outcomes of youth. Federal and state laws, professional guidelines, and ethical standards provide a core framework for guidance in the implementation of confidentiality protections in clinical practice. This policy statement provides recommendations for pediatricians and other pediatric health care professionals, clinics, health systems, payers, and electronic health record developers to optimize confidentiality practices and protections for adolescents and young adults across the spectrum of care.

Emergency contraception - A review

Emergency contraception (EC), or postcoital contraception, is a therapy aimed at preventing unintended pregnancy after an act of unprotected or under-protected sexual intercourse. Options include both emergency contraceptive pills (most commonly containing levonorgestrel or ulipristal acetate) and insertion of an intrauterine device. The aim of this paper is to summarize current evidence surrounding the use of emergency contraceptives and to present an evidence-based approach to EC provision. Emergency contraception is a safe and effective option in preventing unwanted pregnancy, irrespective of age, weight, or breastfeeding status. Efforts should be made to increase their availability, as well as knowledge of these methods, both among patients and healthcare providers.

Early-stage pregnancy recognition on microblogs: Machine learning and lexicon-based approaches

Pregnancy carries high medical and psychosocial risks that could lead pregnant women to experience serious health consequences. Providing protective measures for pregnant women is one of the critical tasks during the pregnancy period. This study proposes an emotion-based mechanism to detect the early stage of pregnancy using real-time data from Twitter. Pregnancy-related emotions (e.g., anger, fear, sadness, joy, and surprise) and polarity (positive and negative) were extracted from users' tweets using NRC Affect Intensity Lexicon and SentiStrength techniques. Then, pregnancy-related terms were extracted and mapped with pregnancy-related sentiments using part-of-speech tagging and association rules mining techniques. The results showed that pregnancy tweets contained high positivity, as well as significant amounts of joy, sadness, and fear. The classification results demonstrated the possibility of using users' sentiments for early-stage pregnancy recognition on microblogs. The proposed mechanism offers valuable insights to healthcare decision-makers, allowing them to develop a comprehensive understanding of users' health status based on social media posts.

After morning, phew! A knowledge, attitudes, and practices survey related to emergency oral contraception in Thai pharmacists

INTRODUCTION

Pharmacists' knowledge and attitude toward Emergency Oral Contraception (EOC) can affect users' access to EOCs, especially where EOCs are provided by pharmacists without the need for prescriptions. We conducted a Knowledge, Attitudes, and Practice (KAP) survey on Thai pharmacists to better understand KAP related to EOCs and the correlation among KAP components.

METHODS

An in-depth interview, GoogleTrend search, and Pantip.com search were conducted. The findings, together with data from a previously published systematic review and meta-analysis, were used to develop KAP survey questions which were distributed online. Spearman's rank correlation coefficient and linear mixed model were used to investigate the correlation and association among KAP components.

RESULTS

The in-depth interview with pharmacists showed that sex and unwanted pregnancy are very sensitive topics in Thailand. Sex and EOC education should be provided by parents and healthcare professionals at a young age. This agreed with opinions from Thai internet users that sex literacy was generally low and sex education was not provided adequately. From the total of 421 survey responses, Thai pharmacists had average knowledge, poor attitude, and average practice related to EOCs (median score = 51.02%, 21.81%, and 60.0%, respectively). The correlations between KAP in pharmacists were weak (ρ = 0.107-0.525, p < 0.02). Pharmacists who rated themselves as having higher scores in knowledge and attitude also rated themselves higher in the practice score. However, the total scores describing the knowledge of or attitude toward EOCs were not associated with EOC practice scores.

CONCLUSIONS

In Thai pharmacists, self-rating KAP scores overestimated total KAP scores. The correlation among KAP components was weak. EOC knowledge and attitudes should be promoted, although this may not improve EOC practice in Thai pharmacists.

Why are pediatricians uncomfortable with prescribing emergency contraception for adolescents?

OBJECTIVE

Emergency contraception (EC) is an effective and safe method for preventing unplanned pregnancy after unprotected sexual intercourse among adolescents but is infrequently prescribed by pediatricians. Because of the scarcity of data on the discomfort with EC prescription among physicians in Brazil, this study aimed to identify associated factors with discomfort with EC prescription among pediatricians in the state of Amazonas.

METHODS

A web-based, cross-sectional study including sociodemographic data, knowledge, attitudes, and discomfort with EC prescription was used. Multivariate logistic regression and artificial intelligence methods such as decision tree and random forest analysis were used to identify factors associated with discomfort with EC prescriptions.

RESULTS

Among 151 physicians who responded to the survey, 53.0% were uncomfortable with prescribing EC, whereas only 33.1% had already prescribed it. Inexperience was significantly associated with discomfort with EC prescription (odds ratio 4.47, 95% confidence interval 1.71-11.66). Previous EC prescription was protective against discomfort with EC prescription in the three models.

CONCLUSIONS

EC is still infrequently prescribed by pediatricians because of inexperience and misconceptions. Training these professionals needs to be implemented as part of public health policies to reduce unplanned adolescent pregnancy.

Contraceptive methods in adolescence: a narrative review of guidelines

PURPOSE

Adolescent pregnancy, while recently in decline, remains a matter in need of addressing. Education and counselling are deemed crucial and this review aims at comparing published contraceptive guidelines, thus resolving any surrounding misconceptions.

MATERIALS AND METHODS

Recently published contraception guidelines regarding adolescent pregnancy were retrieved. In particular, guidelines and recommendations from ACOG, RCOG, SOCG, AAP, CPS, NICE, CDC, and WHO were compared and reviewed based on each guideline's method of reporting.

RESULTS

Three categories of contraceptive methods are available for adolescents and recommendations on their initiation should be made based on their efficacy, according to all guidelines. Therefore, long acting reversible contraceptives (LARCs) should be highly recommended as the most effective method (typical use failure rate: 0.05%), followed by short-acting hormonal contraceptives (typical use failure rate: 3-9%). The third contraceptive option includes contraceptives used in the moment of intercourse and displays the lowest effectiveness (typical use failure rate: 12-25%), mostly due to its dependence on personal consistency, however offers protection against STI transmission.

CONCLUSION

Adolescents should be encouraged to initiate contraception, with LARCs being the primary choice followed by short-acting hormonal contraception. However, regardless of the chosen effective contraceptive method, the use of condom is necessary for STI prevention.

Emergency Contraception: Access and Challenges at Times of Uncertainty

BACKGROUND

The UN Commission on Life-Saving Commodities for Women's and Children's Health identified emergency contraceptive pills as 1 of the 13 essential underused, low-cost, and high-impact commodities that could save the lives of millions of women and children worldwide. In the US, 2 emergency contraceptive regimens are currently approved, and their most plausible mechanism of action involves delaying and/or inhibiting ovulation.

AREAS OF UNCERTAINTY

Abortion and contraception are recognized as essential components of reproductive health care. In the US, in the wake of the Dobbs v. Jackson Women's Health Organization Supreme Court decision on June 24, 2022, 26 states began to or are expected to severely restrict abortion. It is anticipated that these restrictions will increase the demand for emergency contraception (EC). Several obstacles to EC access have been described, and these include cost, hurdles to over-the-counter purchase, low awareness, myths about their mechanisms of action, widespread misinformation, and barriers that special populations face in accessing them. The politicization of EC is a major factor limiting access. Improving sex education and health literacy, along with eHealth literacy, are important initiatives to improve EC uptake and access.

THERAPEUTIC ADVANCES

A randomized noninferiority trial showed that the 52 mg levonorgestrel intrauterine device was noninferior to the copper intrauterine device when used as an EC method in the first 5 days after unprotected intercourse. This is a promising and highly effective emergency contraceptive option, particularly for overweight and obese patients, and a contraceptive option with a different bleeding profile than the copper intrauterine device.

CONCLUSIONS

EC represents an important facet of medicine and public health. The 2 medical regimens currently approved in the US are very effective, have virtually no medical contraindications, and novel formulations are actively being investigated to make them more convenient and effective for all patient populations. Barriers to accessing EC, including the widespread presence of contraception deserts, threaten to broaden and accentuate the already existing inequities and disparities in society, at a time when they have reached the dimensions of a public health crisis.

Trends in Emergency Contraceptive Use Among Adolescents and Young Adults, 2006-2017

PURPOSE

In 2013, age restrictions for adolescents on over-the-counter access were removed for "Plan B One-Step", a single oral medication option for emergency contraception use. Restrictions on generic options of the emergency contraceptive pill (ECP) were removed in 2014.

METHODS

National Survey of Family Growth data were used to assess the prevalence of ever use of ECPs among sexually experienced female adolescents and young adults (AYA) aged 15-24 years (2015-2017 sample), and trends in indicators of ECP use and acquisition (2006-2017 samples). Prevalence estimates were obtained by age subgroups for 15-17, 18-19, and 20-24 years. Statistical significance was determined using an alpha of .05 and 95% confidence intervals calculated around the point estimates.

RESULTS

The weighted estimate of sexually experienced female AYA in the United States ranged from 13.3 million in 2006-2008 to 12.7 million in 2015-2017. The prevalence of ever ECP use was 18.2% (95% CI 15.7-21.1) and 31.8% (95% CI 26.9-37.1) in 2006-2008 and 2015-2017, respectively. Ever use in 2015-2017 varied by age group, number of lifetime opposite-sex partners and abortions, and experience of nonconsensual sex. In 2008-2010, 46.1% (95% CI 36.0-56.5) of respondents last obtained ECPs at community health or family planning clinics, and 31.8% (95% CI 22.9-42.2) last obtained ECPs at a pharmacy compared to 18.1% (95% CI 12.0-26.4) and 70.1% (95% CI 60.6-78.1) respectively in 2015-2017. Prevalence of provider counseling about emergency contraception in female AYA regardless of prior sexual experience in the past 12 months remained at or below 5% from 2006 to 2017.

CONCLUSION

Increasing access to ECPs over-the-counter may have contributed to notable increases in reported ever use of ECPs and in the receipts from a pharmacy among AYA between 2006 and 2017. AYA may benefit if pharmacists and healthcare providers increase reproductive health counseling.

Changes in U.S. Healthcare Provider Practices Related to Emergency Contraception

INTRODUCTION

Emergency contraception (EC), including EC pills (ECPs) and the copper intrauterine device, can prevent pregnancy after sexual encounters in which contraception was not used or used incorrectly. The U.S. Selected Practice Recommendations for Contraceptive Use (U.S. SPR), initially released in 2013, provides evidence-based clinical recommendations on the provision of EC. The objective of this analysis was to assess the percentage of health care providers reporting frequent provision of select EC practices around the time of and after the release of the U.S. SPR.

METHODS

We conducted two cross-sectional mailed surveys using different nationwide samples of office-based physicians and public-sector providers in 2013 and 2014 (n = 2,060) and 2019 (n = 1,420). We compared the percentage of providers reporting frequent provision of select EC practices by time period, overall, and by provider type.

RESULTS

In 2019, few providers frequently provided an advance prescription for ECPs (16%), an advance supply of ECPs (7%), or the copper intrauterine device as EC (8%), although 41% frequently provided or prescribed regular contraception at the same time as providing ECPs. Providers in 2019 were more likely than providers in 2013 and 2014 to provide or prescribe contraception at the same time as providing ECPs (adjusted prevalence ratio, 1.26; 95% confidence interval, 1.001-1.59) and to provide a copper intrauterine device as EC (adjusted prevalence ratio, 3.87; 95% confidence interval 2.10-7.15); there were no other significant differences by time period.

CONCLUSIONS

Few providers report frequent implementation of recommended EC practices. Understanding the barriers faced by providers and clinics in implementing these practices may improve access to EC.

COVID-19 and family planning service delivery: Findings from a survey of U.S. physicians

Equitable access to contraception is critical for reproductive autonomy. Using cross-sectional data from the DocStyles survey administered September-October 2020 (68% response rate), we compared changes in family planning-related clinical services and healthcare delivery strategies before and during the COVID-19 pandemic and assessed service provision issues among 1063 U.S. physicians whose practice provided family planning services just before the pandemic. About one-fifth of those whose practices provided the following services or strategies just before the pandemic discontinued these services during the pandemic: long-acting reversible contraception (LARC) placement (16%); LARC removal (17%); providing or prescribing emergency contraceptive pills (ECPs) in advance (18%); and reminding patients about contraception injections or LARC removal or replacement (20%). Many practices not providing the following services or strategies just before the pandemic initiated these services during the pandemic: telehealth for contraception initiation (43%); telehealth for contraception continuation (48%); and renewing contraception prescriptions without requiring an office visit (36%). While a smaller proportion of physicians reported service provision issues in the month before survey completion than at any point during the pandemic, about one-third still reported fewer adult females seeking care (37%) and technical challenges with telehealth (32%). Discontinuation of key family planning services during the COVID-19 pandemic may limit contraception access and impede reproductive autonomy. Implementing healthcare service delivery strategies that reduce the need for in-person visits (e.g., telehealth for contraception, providing or prescribing ECPs in advance) may decrease disruptions in care. Resources exist for public health and clinical efforts to ensure contraception access during the pandemic.

The Role of Health Care Providers in Young Women's Attitudes about and Willingness to Use Emergency Contraceptive Pills

BACKGROUND

Emergency contraceptive pills (ECPs) are an underused resource among adolescent and young adult women who have unprotected sex. This analysis examines young women's attitudes about and willingness to use ECPs, with particular attention to their experiences with health care providers.

METHODS

Sexually active young women (ages 15-25, assigned female at birth, N = 212) completed a self-administered survey at 10 family planning clinics in the San Francisco Bay Area. Participants reported attitudes about ECP effectiveness, safety, effect on sex drive, and whether it should not be taken often, and their willingness to use ECPs in the next 3 months. The predictors of interest were past and current contraceptive experiences with health care providers. Data were analyzed through descriptive statistics and multivariable logistic regression analyses controlling for sociodemographic characteristics, prior contraceptive use, pregnancy history, and pregnancy intentions.

RESULTS

Most young women agreed that ECPs are effective at preventing pregnancy (75%) and safe to use (71%); few reported that they reduce sex drive (11%). Yet, the majority (62%) believed ECPs should not be taken often and only 35% reported willingness to use ECPs. In multivariable analyses, more positive health care experiences were associated with more positive attitudes about ECP safety, less concern that ECPs should not be taken often, and greater willingness to use ECPs (p < .05).

CONCLUSIONS

Health care providers play an important role in the acceptance and provision of ECPs, especially for young women who prefer ECPs over other contraceptive methods. In particular, providers can use the contraceptive visit as an opportunity to destigmatize repeat ECP use.

Population Geography and Emergency Contraception Access in Louisiana

We assessed the same-day availability of oral emergency contraception (EC) in five Louisiana communities, and evaluated this data for relationships between availability and local population demographics. Researchers called all retail pharmacies in five municipalities of varying sizes in order to inquire about the same-day stockage of EC products and their availability to teens. Individual pharmacies were then geolocated to a census tract, and call data was analyzed against neighborhood census data regarding population size, income, gender, race, family structure, and educational level. A multivariable logistic regression model was performed to predict the same-day availability of emergency contraception. EC was available on the same day in 66% of all pharmacies. The same-day availability of EC decreased with the local population size (p < 0.001), and the availability increased with higher levels of educational attainment (p = 0.0015). The largest census level predictor of access to same-day EC was the city population, with the availability increasing by 6.6% for every 10,000 person increase in population. Despite changing to over-the-counter sales in 2013, EC is still not widely available in all geographic areas. Its availability is partially predictable by local population demographics, and this difference may represent a health disparity for teens and women seeking EC.

A Systematic Review and Meta-analysis of the Adverse Effects of Levonorgestrel Emergency Oral Contraceptive

INTRODUCTION

The levonorgestrel oral emergency contraceptive is well tolerated and effective, however its use is still limited, mainly due to safety concerns.

OBJECTIVE

This systematic review and meta-analysis aimed to summarize current evidence regarding the adverse events, and their prevalence, reported during the use of oral levonorgestrel emergency contraceptives.

METHODS

Four electronic databases and the US FDA Adverse Event Reporting System (FAERS) Public Dashboard were searched. Studies that reported or investigated safety outcomes or adverse reactions during the use of levonorgestrel as an emergency oral contraceptive were included. Data on study design, demographics of levonorgestrel and the control cohort, and reported adverse effects were extracted.

RESULTS

A total of 47 articles were included in this systematic review, from which it was shown that most of the adverse reactions were common and not serious. Uncommon adverse reactions identified included anorexia, ectopic pregnancy, exanthema, chloasma, miscarriage, and weight gain. Multiple serious adverse events, including convulsion, ectopic pregnancy, febrile neutropenia, stroke, abdominal hernia, anaphylaxis, cancer, ovarian cyst rupture, serious infections, and suicidal ideation, were reported. In addition, the prevalence of adverse events after a levonorgestrel 0.75 mg two-dose regimen and a levonorgestrel 1.5 mg single-dose regimen were not statistically different (p > 0.05).

CONCLUSIONS

The most common adverse effects of levonorgestrel were not serious. This systematic review shows that data regarding the adverse reactions of repeated use of levonorgestrel are scarce. Studies on the multiple uses of levonorgestrel emergency contraception are still required to ensure its safety.

Exploring young women's reasons for adopting intrauterine or oral emergency contraception in the United States: a qualitative study

BACKGROUND

The recent focus on increasing access to long-acting reversible contraceptive methods has often overlooked the diverse reasons why women may choose less effective methods even when significant access barriers have been removed. While the copper intrauterine device (IUD) is considered an acceptable alternative to emergency contraception pills (ECPs), it is unclear to what extent low rates of provision and use are due to patient preferences versus structural access barriers. This study explores factors that influence patients' choice between ECPs and the copper IUD as EC, including prior experiences with contraception and attitudes toward EC methods, in settings where both options are available at no cost.

METHODS

We telephone-interviewed 17 patients seeking EC from three San Francisco Bay Area youth-serving clinics that offered the IUD as EC and ECPs as standard practice, regarding their experiences choosing an EC method. We thematically coded all interview transcripts, then summarized the themes related to reasons for choosing ECPs or the IUD as EC.

RESULTS

Ten participants left their EC visit with ECPs and seven with the IUD as EC option. Women chose ECPs because they were familiar and easily accessible. Reasons for not adopting the copper IUD included having had prior negative experiences with the IUD, concerns about its side effects and the placement procedure, and lack of awareness about the copper IUD. Women who chose the IUD as EC did so primarily because of its long-term efficacy, invisibility, lack of hormones, longer window of post-coital utility, and a desire to not rely on ECPs. Women who chose the IUD as EC had not had prior negative experiences with the IUD, had already been interested in the IUD, and were ready and able to have it placed that day.

CONCLUSIONS

This study highlights that women have varied and well-considered reasons for choosing each EC method. Both ECPs and the copper IUD are important and acceptable EC options, each with their own features offering benefits to patients. Efforts to destigmatize repeated use of ECPs and validate women's choice of either EC method are needed to support women in their EC method decision-making.
