Safety and Risk Surveillance era
Martin Vessey [1] was a prominent figure in the Safety and Risk Surveillance era, with affiliations at Harvard University [2] and Boston University [3]. His key contribution during this era was the 1970 report on thromboembolic disease and the steroidal content of oral contraceptives [4], which helped quantify cardiovascular and thromboembolic risks and informed regulatory labeling and risk communication. Building on that work, Vessey further shaped risk surveillance practices for contraception by emphasizing the need for systematic post-market monitoring and epidemiologic evaluation [4]. These contributions established methodological templates and regulatory expectations that guided ongoing product evaluation and public health responses in this era [4].
Policy and Service Delivery era
Lawrence B. Finer[1] was associated with University of California, San Francisco[3] and Johns Hopkins University[4] during the 1980–2016 Policy and Service Delivery era. His quantitative work on disparities in unintended pregnancy, notably Disparities in Rates of Unintended Pregnancy In the United States, 1994 and 2001[7] and Unintended pregnancy in the United States: incidence and disparities, 2006[8], highlighted population-level inequities and helped reframe access pathways and service delivery in policy-guided programs. Stanley K. Henshaw[2] was affiliated with University of Illinois Chicago[5] and Baruch College[6] during the era. His analysis of disparities in unintended pregnancy, as captured in Disparities in Rates of Unintended Pregnancy In the United States, 1994 and 2001[7], supplied critical population-level evidence that informed policy analysis and scalable service-delivery responses.
Autonomy-Centered Care era
Jody Steinauer [1] is affiliated with Harvard University [3] and the University of California, San Francisco [4] in the Autonomy-Centered Care era. Her key contributions include advancing shared decision making in contraceptive counseling as documented in Shared decision making in contraceptive counseling [6], which operationalized patient preferences and informed choice to support autonomy-based care. Christine Dehlendorf [2] is associated with University of California, San Francisco [4] and Stanford University [5] during this era. Her work on shared decision making in contraceptive counseling, as captured in Shared decision making in contraceptive counseling [6], helped translate autonomy-centered guidelines into policy and practice to enhance value-concordant care.
