Brief Summary:
Study to analyze electronic medical records of women using an intrauterine device (IUD). The study was required by the FDA for the marketed IUD Mirena (US Post-marketing requirement; short name of study: APEX IUD).
The study analyzed the risks that the IUD was expelled or perforated the womb for the following group comparisons:
* Women who were breastfeeding at the time of IUD insertion and within 52 weeks postpartum versus women who were not breastfeeding at the time of IUD insertion and within 52 weeks postpartum.
* Women who had a first observed IUD insertion within different time periods after childbirth (i.e., ≤ 6 weeks, \> 6 weeks and ≤ 14 weeks, \> 14 weeks and ≤ 52 weeks) versus women who had their first observed IUD insertion more than 52 weeks after childbirth, including women without a recorded delivery within the past 52 weeks. An additional analysis involved 5-level postpartum timing (i.e., 0 to 3 days, 4 days to ≤ 6 weeks, \> 6 weeks to ≤ 14 weeks, \> 14 weeks to ≤ 52 weeks) versus the \> 52 week postpartum group.
The study also analyzed the risks that the IUD was expelled or perforated the womb for different types of IUDs. In addition, the study aimed to assess the following interactions:
* The extent to which the type of IUD (IUDs releasing the hormone LNG versus Copper IUDs) modified the risk that an IUD was expelled or perforated the womb in relation to breastfeeding and/ or in relation to the point in time when the IUD was inserted after childbirth.
* The extent to which the breastfeeding status modified the risk that an IUD was expelled or perforated the womb in relation to the point in time when the IUD was inserted after childbirth.
