Safety and Expulsion of Delayed Versus Immediate Postpartum Intrauterine Device Placement

Not Applicable

Terminated

Conditions: Contraception

Interventions: Device: Mirena (levonorgestrel-releasing intrauterine system)

Registration Number: NCT01598662

Lead Sponsor: University of Louisville

Brief Summary: This is randomized controlled trial designed for pregnant women who deliver vaginally at the University of Louisville Hospital and desire to have an intrauterine device (IUD) inserted for postpartum contraception. After informed consent is obtained, eligible study participants will be randomized to receive the Mirena® IUD at the 6 week postpartum visit or within 10 minutes of delivery of the placenta following a normal vaginal delivery. The investigators seek to determine the expulsion rate and complication rate in subjects with IUD immediately after placental delivery compared to insertion at six weeks postpartum or later. The investigators hypothesize that immediate placement safe and has an acceptably low expulsion rate to merit earlier placement in the indigent population.

Detailed Description: Unintended pregnancy occurs in nearly half of all pregnancies in the United States. There are many barriers to implementation of long-term reversible contraception in the immediate postpartum period. In our indigent population, a survey of patients showed that nearly 60% of patients who chose an IUD while admitted postpartum never returned for placement, placing them at risk for early repeat pregnancy.

The intrauterine device is a safe and effective form of long-term reversible contraception when placed at 6 weeks postpartum or later with pregnancy rates of only 0.1%. The commercially available Mirena IUD contains levonorgestrel which is released slowly over five years, providing safe, reversible contraception and making menstrual flow much lighter.

This randomized controlled trial will compare traditional placement at 6 weeks or more postpartum versus immediate post-placental placement.

The investigators hypothesize that the expulsion rate of IUDs placed immediately postpartum will be acceptably low in an indigent population to still be cost effective. Studies from the world literature in Egypt and Mexico where IUDs are routinely placed immediately following placental delivery.support this hypothesis. A recent study published in 2010 by Chen et al. showed an approximately 24% expulsion rate.

Six week postpartum IUD placement for contraception will be compared to immediate post-placental IUD placement, to determine whether immediate IUD insertion after delivery has an acceptably low rate of expulsion, infection, perforation and unintended pregnancy, and a high rate of retention, patient satisfaction, and maintenance of contraception.

Arm && Interventions

Group	Intervention	Description
2: Immediate Post-placental insertion	Mirena (levonorgestrel-releasing intrauterine system)	Device: Levonorgestrel-releasing intrauterine device marketed as Mirena Subjects randomized to immediate post-placental placement within 10 minutes of delivery will have an IUD placed manually under sterile technique and with ultrasound guidance. An ultrasound will be performed within two days postpartum to verify proper placement and again at approximately six weeks postpartum.
1: IUD insertion 6 Weeks after delivery	Mirena (levonorgestrel-releasing intrauterine system)	Device:Levonorgestrel-releasing intrauterine device marketed as Mirena. Subjects randomized to interval placement will have their IUD placed in the office at six weeks postpartum or later. They must return for one visit within a month for a "string check".

Primary Outcome Measures

Name	Time	Method
IUD Expulsion Rate	6 months	The investigators wanted to compare the expulsion rate of IUDs between the two treatment arms: immediate placement after placental delivery and interval placement 6 weeks after delivery. IUD expulsion is confirmed by the inability of the physician to visualize the string attached to the IUD coming from the cervix.
