Assessing Pain and Effectiveness of Carevix Device for IUD Insertions

Официальное название

The Carevix Device: Assessing Pain and Effectiveness of a Suction-based Cervical Stabilizer for IUD Insertions in the Clinic Setting: a Randomized, Controlled Trial (CARE)

Обзор

The goal of this clinical trial is to evaluate patient-reported pain, bleeding, and device efficiency along with provider satisfaction and ease of use between IUD insertions using a suction cervical stabilizer (new device, FDA approved, atraumatic) and single-tooth tenaculum (standard, traumatic). Our aims are to: * assess and compare patient-reported pain during IUD insertion between the Carevix device and tenaculum. * assess predictors of pain scores including between nulliparous and multiparous patients * assess provider-reported ease of use and satisfaction Participants (including providers) will: * be randomized to receive one device to complete the IUD procedure * complete a survey following the procedure

Подробное описание

The primary objective is to assess and compare patient-reported pain during IUD insertion between the Carevix device and tenaculum. The hypothesis is that patient-reported pain scores comparing Carevix™ to tenaculum will be lower. The investigators will assess pain, and predictors for pain scores including nulliparous vs multiparous, when highest pain scores are reported, and expectation of pain for the procedure.

The secondary objective will be to assess Usability (provider assessment of ease of use, number of device placement attempts to secure sufficient traction on uterus), efficacy (ability to insert IUD with Carevix™ device alone without recourse to conventional tenaculum or other instruments), provider reported bleeding (cervical bleeding and ecchymosis), overall provider satisfaction, patient-reported pain scores at device placement prior to IUD insertion procedure and after completion of IUD insertion using Visual Analog Scale (VAS), overall patient satisfaction, and overall provider satisfaction. The investigators aim to expand the pilot trial data collection to assess cultural background, ethnicity and demographics while also assessing prior contraceptive choices, reasons for discontinuation of prior choices and reasons for current selection of IUD insertion and any anticipated barriers for removal.
