BACKGROUND: In 2002, the Kaiser Foundation Health Plan in California changed its coverage policy to include 100% universal coverage for the most effective forms of contraception and for emergency contraceptive pills (ECPs). This study sought to evaluate whether removing the cost of contraception as a potential barrier to utilization would lead to a change in the mix of contraceptive methods prescribed and purchased by a large health plan and whether those changes could theoretically result in averting a greater number of unintended pregnancies. STUDY DESIGN: A retrospective observational study was conducted to describe the mix of reversible contraceptives procured before and after the benefit change at Kaiser Permanente Northern California. We then estimated couple-years of protection (CYP) to examine whether the contraceptive mix changed to more effective reversible methods. RESULTS: After the contraceptive benefit change, CYP increased by 28% (from 2001-2002 to 2003-2004), while the number of females aged 15-44 enrolled in this health plan fell by 1%. CYP for intrauterine contraceptives (IUCs) and injectables rose by 137% and 32%, respectively, while CYP for the pill, patch and ring rose only by 16%. The estimated average annual contraceptive failure rate among women using hormonal contraceptives and IUCs declined from 7.0% to 6.4%. Purchasing of the ECP rose by 88%. CONCLUSION: Removal of the cost of contraception may result in increased utilization of more effective methods and ECPs.
