Abstract
Question
Is legislation requiring insurers to cover 12 months of short-acting hormonal contraception associated with an increase in 12-month contraceptive prescriptions?
Findings
This cohort study found that more than 80% of prescriptions for contraceptives cover 3 months or fewer. Legislation mandating insurance coverage of annual prescriptions was not associated with an increase in 12-month prescriptions, although it was associated with a shift from 1-month prescriptions to prescriptions for 2 to 3 months.
Meaning
Eliminating the need to return to a pharmacy every 30 or 90 days to refill prescriptions will likely require changes beyond insurance coverage and may necessitate outreach and education to clinicians and insurers.
Importance
Eighteen states, including Oregon, have passed legislation requiring insurers to cover dispensation of a 12-month supply of short-acting, hormonal contraception.
Objective
To determine whether Oregon’s 2016 12-month supply law was associated with an increase in contraceptive supply received.
Design, Setting, and Participants
This retrospective cohort study of hormonal contraceptive users using Oregon’s All Payer All Claims database examined the quantity of contraceptive supply dispensed 3 years before and 3 years after the 2016 policy change. We also assessed changes among patients attributed to Title X clinics.
Exposures
Legislation requiring insurers in Oregon to cover a 12-month supply of contraception to continuing users.
Main Outcomes and Measures
Receipt of a 12-month supply of hormonal contraception
Results
This cohort study of insured users (mean [SD] age, 27.4 [2.1] years) of short-acting hormonal contraception included 639 053 contraceptive prescriptions. Results indicated that more than 80% of prescriptions for contraceptives cover 3 months or fewer. Most women in the study population used the oral contraceptive pill, lived in a metropolitan area, and were privately insured. We did not observe a significant association between the passage of the 12-month supply policy and receipt of a 12-month supply (aOR, 1.01; 95% CI, 0.74-1.38). Receipt of a 12-month supply was more common for Medicaid recipients than the privately insured (aOR, 9.40; 95% CI, 6.62-13.34). We did find a shift from 1 month to 2 to 3 months supply being dispensed. The policy change was associated with a small, overall increase in quantity dispensed (0.27 months supply; 95% CI, 0.15 to –0.38). Title X clinics prescribed 3 months more of contraceptive supply than non–Title X clinics (3.03 months supply; 95% CI, 2.64-3.41). However, the policy change was not associated with increased contraceptive supply dispensed at Title X clinics.
Conclusions and Relevance
In this cohort study of insured users of short-acting hormonal contraception, the passage of a 12-month contraceptive supply policy was not associated with an increase in contraceptive supply dispensed.
