Abstract

Importance:

The Veterans Affairs (VA) health care system is the largest integrated health care system in the United States. Like most US health plans, the VA currently stipulates a 3-month maximum dispensing limit for all medications, including oral contraceptive pills (OCPs). However, 12-month OCP dispensing has been shown to improve continuation of use, decrease coverage gaps, and reduce unintended pregnancy in other practice settings.

Objective:

To estimate the financial and reproductive health implications for the VA of implementing a 12-month OCP dispensing option, with the goal of informing policy change.

Design, Setting, and Participants:

A decision model from the VA payer perspective was developed to estimate incremental costs to the health care system of allowing the option to receive a 12-month supply of OCPs up front, compared with the standard 3-month maximum, during a 1-year time horizon. A model cohort of 24 309 reproductive-aged, heterosexually active, female VA enrollees who wish to avoid pregnancy for at least 1 year was assumed. Probabilities of continuation of OCP use, coverage gaps, pregnancy, and pregnancy outcomes were drawn from published data. Costs of OCP provision and pregnancy-related care and the number of women using OCPs were drawn from VA administrative data. One-way and probabilistic sensitivity analyses were performed to assess model robustness.

Main Outcomes and Measures:

Incremental per-woman and total costs to the VA of allowing for 12-month dispensing of OCPs compared with standard 3-month dispensing.

Results:

The 12-month OCP dispensing option, modeled from the VA health system perspective using a cohort of 240 309 women, resulted in anticipated VA annual cost savings of $87.12 per woman compared with the cost of 3-month dispensing, or an estimated total savings of $2 117 800 annually. Cost savings resulted from an absolute reduction of 24 unintended pregnancies per 1000 women per year with 12-month dispensing, or 583 unintended pregnancies averted annually. Expected cost savings with 12-month dispensing were sensitive to changes in the probability of OCP coverage gaps with 3-month dispensing, the probability of pregnancy during coverage gaps, and the proportion of pregnancies paid for by the VA. When simultaneously varying all variables across plausible ranges, the 12-month strategy was cost saving in 95.4% of model iterations.

Conclusions and Relevance:

Adoption of a 12-month OCP dispensing option is expected to produce substantial cost savings for the VA while better supporting reproductive autonomy and reducing unintended pregnancy among women veterans.
