Association of 12-month contraceptive supply policy and months of oral contraception prescribed by obstetrics and gynecology resident physicians: an exploratory cross-sectional study

Objective: This study sought to determine if there was a difference in the months of oral contraception prescribed by resident physicians living in U.S. states with a 12-month supply policy compared to resident physicians in states without a policy. Methods: We conducted an exploratory descriptive study using a convenience sample of Obstetrics and Gynecology resident physicians (n = 275) in the United States. Standard bivariate analyses were used to compare the difference between groups. Results: Few resident physicians in both groups (3.8% with a policy and 1.4% without a policy) routinely prescribed a 12-month supply of contraception. The mean coverage prescribed by providers in states with and without a policy was 2.81 and 2.07 months (p < 0.05). Conclusions: The majority of resident physicians were unaware of 12-month contraceptive supply policies and unable to correctly write a prescription for 12-months of contraception, regardless of whether they lived in a state with a 12-month contraceptive supply policy. Physician education may be needed to effectively implement 12-month contraceptive supply policies.
