Contraceptive Access

Our research aims to improve access to contraception while reducing coercion and provider bias through patient-centered approaches to care. We investigate structural inequities and basic needs adversity that stand in the way of access to contraception. We also identify educational and medical barriers that hinder access, especially among underserved populations, including adolescents and young adults. Our studies evaluate approaches to expand access to contraception, including

  • Raising awareness of contraceptive options, where to find them, and risks and benefits
  • Increasing venues to access contraception including the pharmacy and telemedicine
  • Training providers to offer high quality, evidence-based counseling and a wide array of methods
  • Provision of care in varied practice settings
  • Elimination of unnecessary medical exams and visit requirements

As part of the effort to expand access, we have evaluated the provision of contraception in a range of practice settings, including community clinics, pharmacies, primary care, school-based clinics, and abortion providers. We have conducted studies on over-the-counter and direct pharmacy access to emergency contraception, advance provision, and telemedicine access to contraception.

We educate reproductive age populations and providers on new methods, including ones that are especially useful today, such as self-administered Depo-SubQ that does not require clinic visits and Opill® that is available directly at the pharmacy.

We have studied health care providers’ contraceptive education and counseling practices to assess the extent to which they are evidence-based and to identify the need for training on contraceptive eligibility and indications.

Our research has also focused on streamlining access to reproductive health care and reducing unnecessary medical tests, including removing the pelvic exam requirement for hormonal contraception. The pelvic examination can present an obstacle for patients seeking to prevent pregnancy, especially for adolescents. While the dissemination of new clinical practices can be a lengthy process, our research has helped to move reproductive health care in the direction of greater clinic efficiency and improved patient health outcomes.

Self-administered Depo-SubQ more available during COVID-19, but overall availability remains low

According to our 2024 study published in Contraception, although self-administered Depo-SubQ increased during the COVID-19 pandemic, the method availability remains persistently low. Depo-SubQ is a lower hormone injectable method that can accessed directly at the pharmacy and administered at home without a clinic visit.
