Objective:
To evaluate the impact of length of the Medicaid sterilization waiting period and postpartum permanent contraception fulfillment.
Study Design:
Simulations from a retrospective cohort study estimating the potential increase in permanent contraception within 365 days of delivery.
Results:
In our sample of 2076 patients, 61% achieved permanent contraception with the current waiting period of 30 days. With the waiting period hypothetically reduced to 15, 3, 1, and 0 days, 62.9%, 63.7%, 64.5%, and 75% patients, respectively, would have achieved permanent contraception.
Conclusions:
As potential Medicaid sterilization policy revisions are considered, understanding the impact on fulfillment rates is critical.

Left truncation occurs when individuals who experienced the event of interest before a certain time are not included in the study. This is often due to a "delayed entry" into the study where only those who survive until a certain entry point are...
