This research investigates women’s preferences in Mexico to inform efforts to improve the quality of family planning services. Several key themes emerged from their focus groups.

The study shows significant changes in providers’ attitudes, knowledge and practices in the group that received a 4-hour continuing education course that shared updated evidence on IUDs and implants and hands-on training on IUD insertion and contraceptive counseling.

This research shows that very few young women had heard of using the IUD as a form of emergency contraception.

This paper shows that significant barriers exist to community health centers providing intrauterine devices (IUDs).

This research shows that even in a state where Medicaid covers abortion and birth control for low-income women, some still face cost-related barriers.

This research shows that providing family planning care to patients without the participation of established women’s health organizations presents serious challenges.

This study used audio recordings of visits, as well as patient surveys, to analyze both their quality and content. The vast majority satisfied with “how their provider helped them choose a contraceptive method.” At the same time, the analysis also revealed several areas in which providers can improve communication.

The study found that, among 1,700 publicly insured postpartum women in Texas, only about half of those who preferred a long-acting method were actually using one six months after delivery. The “use gap” was roughly the same for women who preferred sterilization.

More than in one in five women reported interest in using a self-administered birth control shot, which could improve contraceptive continuation by removing the difficulty of having to return to a clinic for repeat injections.

Public funding expands young women’s access to birth control, especially for methods with high up-front costs like intrauterine devices and implants.

In focus group discussions with African-American women, Asian-American women and young women, researchers found that a broad range of women support over-the-counter access to the pill. Benefits of particular interest were the convenience and privacy of getting the pill OTC. Concerns included cost and the worry that first-time and young users may not have enough information to use the pill properly.

The rate of unintended pregnancy can be reduced by training providers to routinely include long-acting reversible methods in their contraceptive counseling.

On the basis of the model of the Lancet Commission, we suggest that a group of experts from the Sahel and research institutions elsewhere in the world should be convened to explore and document the cross-sectoral, scalable initiatives needed to avoid the Sahel (and other least developed regions) being totally excluded from the promise of improved health and welfare foreseen in the Lancet Commission.

To achieve optimal birth spacing and ultimately to improve birth outcomes, attention should be given to contraceptive counseling and access to contraceptive methods in the postpartum period.

Nurse practitioners have an increasingly important position in addressing high unintended pregnancy in the US, but require specific training in long-acting reversible contraceptives.

Obstetrician-gynecologists perform bimanual pelvic examinations in the vast majority of asymptomatic women, but the importance placed on the examinations and reasons for conducting them vary.

Female condoms were integrated into provider counseling and care, although providers reported a need for new female-initiated multipurpose prevention technologies, suggesting female condoms do not meet all patient/provider needs or are not adequately well known or accessible.

On-site utilization of LARC is a potential quality indicator for family planning programs. Title X resources are associated with increased use of LARC.

Overall, providers viewed increased access to hormonal contraception as an important public health service and supported pharmacy access. They thought that pharmacy access can be accomplished through pharmacist education and training.

The contraceptive features women want are largely absent from currently available methods. Developing and promoting methods that are more aligned with women’s preferences presumably could help increase satisfaction and thereby encourage consistent and effective use.

Nomegestrol acetate and 17[beta]-E2 were well tolerated and provided excellent contraceptive efficacy and acceptable cycle control.

Recommendation of the copper intrauterine device (IUD) for emergency contraception is rare, despite its high efficacy and long-lasting contraceptive benefits. Recommendation would require clinic flow and scheduling adjustments to allow same-day IUD insertions. Patient-centered and high-quality care for emergency contraception should include a discussion of the most effective method.

The reduction in racial and ethnic disparities following introduction of the patch suggests that methods with novel characteristics may increase acceptability of contraceptives among minority women.

Making oral contraceptives more accessible may reduce the incidence of unintended pregnancy and abortion. Health insurance programs and public health programs may avert costly unintended pregnancies by increasing dispensing limits on oral contraceptives to a 1-year supply.
- Foster DG, Hulett D, Bradsberry M, Darney P, Policar M. Obstetrics & Gynecology. March 2011.
Combined hormonal contraception is a popular and effective method of preventing pregnancy. The EE/ENG ring offers improvements over OCs with respect to compliance, cycle control and systemic side effects without compromising contraceptive efficacy.
- Kerns J, Darney PD. Contraception. February 2011.
The patch and the ring may not be better options than the pill or depot medroxyprogesterone acetate for women at high risk for unintended pregnancy. This study highlights the need for counseling interventions to improve contraceptive continuation, education about longer-acting methods, and developing new contraceptives that women may be more likely to continue.

One third of clinicians we surveyed require pelvic examinations before provision of oral contraceptives, despite guidelines indicating they are unnecessary and research suggesting they can pose a barrier to contraceptive access.
- Henderson JT, Sawaya GF, Blum M, Stratton L, Harper CC. Obstetrics & Gynecology. December 2010.
All contraceptive methods were cost-effective – they saved more in public expenditures for unintended pregnancies than they cost to provide. Because no single method is clinically recommended to every woman, it is medically and fiscally advisable for public health programs to offer all contraceptive methods.

The levonorgestrel intrauterine system (LNG-IUS) is both safe and extremely efficacious for use in nulliparous women.

Dispensing a year's supply of oral contraceptive pill cycles to women is associated with higher method continuation and lower costs than dispensing fewer cycles per visit.

While removing the requirement to go through pharmacists or clinics to obtain EC increases use, the public health impact may be negligible because of high rates of unprotected intercourse and relative underutilization of the method. Given that there is clear evidence that neither pharmacy access nor advance provision compromises contraceptive or sexual behavior, it seems unreasonable to restrict access to EC to clinics.

Providing contraceptives to low income, medically indigent women significantly reduced the number of unintended pregnancies in California.

Programs that provide hormonal contraceptives without requiring a pelvic examination can expand low-income women’s access to these methods and improve the chances that they will obtain other reproductive health services.
