COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
The intervention is the insertion of a post-partum intrauterine device (PPIUD) using a dedicated prototype PPIUD insertion device designed specifically for post-partum use. The intervention will entail having a PPIUD (commercially available device, copper or hormone containing IUD) placed within 10 minutes of placental delivery following vaginal birth. The insertion procedure takes less than 5 minutes and is performed once. The device will be inserted by a trained delivery attendant who is part of the research team (senior doctor, midwife or nurse practitioner) using the dedicated prototype device. Bedside ultrasound will b used to verify correct device location inside the uterine cavity immediately following the insertion. Clinical notes will be reviewed to ensure adherence to planned treatment.

Primary outcome [1] 321913 0
Proper function of the dedicated PPIUD inserter device as measured by the number of subjects with the IUD properly positioned at the fundus of the uterus with strings visible. This will be assessed by both clinical exam (visibility of strings) and by ultrasound.

Brief summary
We plan to test a new prototype intrauterine contraceptive device (IUD) inserter designed specifically for postpartum use. The device has been tested in a simulation setting and functions as intended. The device has not been tried in human subjects. The reason for the study is to test that the device functions as intended in actual use.
Ten women will be enrolled. They will consent to have an IUD inserted after normal childbirth. A standard IUD that is already in routine clinical use will be inserted, using the new inserter. The location of the IUD will be confirmed by ultrasound at the time of insertion, within 5-10 days of insertion, and at 42-56 days after insertion.
The clinician inserting the IUD (a member of the research team), and the woman receiving the IUD will complete brief surveys regarding their experiences with the use if the device.
