Twelve month oral contraceptive pill prescriptions: Role of policy mandates on utilization

Recent studies have suggested that extended duration oral contraceptive pills (OCP), such as the 12-month duration, have a positive impact on pregnancy rates but negative impact on pill wastage. Several states have since been mandating health plans to offer extended duration OCP as an option for women. The objective of the study was to evaluate the impact of these mandates on utilization of extended duration OCPs. Using claims data of a large pharmacy benefit manager for commercially insured women from 2018 to 2019, use, adherence, continuity, and wastage of OCPs by women dispensed one-month only, three-months only, 6 or 12-months only, and other months (which includes other months and mixed duration OCP) was retrospectively analyzed. OCP dispensed by year, and adherence, continuity, wastage over a 15-month period were summarized using Chi square and ANOVA. There were 874,420 and 875,914 women in this study in 2018 and 2019 respectively. Of these, 34% were from states with the mandate (SWM). Most women filled the one-month and three-month duration, with very low overall 6 or 12-month duration claims. Proportion of utilizers of 6 or 12- month duration was higher in SWM than in those without, although differences in absolute rates were very low. Patients with OCP discontinuation, gaps ≥7 and 14 days, were fewer among those filling 6 or 12-month duration but conversely, wastage was higher in this group compared to those filling one or three-month duration. Our findings suggest that, among commercially insured women, extended duration OCP mandates have so far not had much influence on use of 6 or 12-month duration OCP prescriptions.
