Study summary

The goal of this clinical trial is to learn if a cervical ripening balloon (Foley balloon) works to prepare the cervix before same-day outpatient dilation and evacuation (D\&E). The main questions it aims to answer are:

  • Is cervical preparation with cervical ripening balloon for same-day outpatient D\&E non-inferior to cervical preparation with osmotic dilators?
  • How feasible and safe is cervical preparation with cervical ripening balloon for same-day outpatient D\&E?
  • How acceptable is cervical preparation with cervical ripening balloon for same-day outpatient D\&E?

Participants will:

  • Have cervical preparation with cervical ripening balloon (experimental group) or osmotic dilators (usual care group)
  • Complete two surveys, one about the cervical preparation and one about the D\&E procedure

What researchers measure

Primary outcomes

  1. D&E procedure length (minutes)

    From insertion of first instrument to removal of speculum

    Time frame: during procedure

Secondary outcomes

  1. Starting dilation (French gauge)

    Pratt dilator size in French gauge (sequential numbered instruments with size corresponding to diameter)

    Time frame: during procedure

  2. Additional dilation (French gauge)

    Pratt dilator size in French gauge (sequential numbered instruments with size corresponding to diameter)

    Time frame: during procedure

  3. Estimated blood loss (milliliters)

    Amount of blood loss, measured in milliliters throughout the procedure

    Time frame: during procedure

  4. Additional sedation medication administered

    yes/no

    Time frame: during procedure

  5. Pain (Visual Analog Scale)

    10 point visual analog scale with values from 0-10, with 0 being "No pain" and 10 being "Worst possible pain." Electronic slider measure so participants can specify up to 0.001 value.

    Time frame: during procedure

  6. Administration of uterotonic medications

    yes/no

    Time frame: during procedure

  7. Cervical laceration

    yes/no

    Time frame: during procedure

  8. Estimated blood loss > 500 milliliters

    yes/no

    Time frame: From enrollment to 24 hours after enrollment

  9. Hospital transfer

    yes/no

    Time frame: From enrollment to 24 hours after enrollment

  10. Feasibility of cervical preparation (physician-reported)

    Yes/ No: "Is this type of cervical prep feasible for future patients" and qualitative free-text responses

    Time frame: From enrollment to 24 hours after enrollment

  11. Likelihood to recommend cervical preparation (participant-reported)

    Modified Likert scale: Very unlikely, Somewhat unlikely, Neither likely nor unlikely, Somewhat likely, Very likely

    Time frame: From enrollment to 24 hours after enrollment

  12. Acceptability of cervical preparation (physician-reported)

    Yes/ No: "Is this type of cervical prep acceptable for future patients" and qualitative free-text responses

    Time frame: From enrollment to 24 hours after enrollment

  13. Satisfaction with level of pain management (participant-reported)

    Yes/ No: "Are you satisfied with your level of pain management..." and qualitative free-text responses

    Time frame: From enrollment to 24 hours after enrollment

ElapsedEstimatedEstimated, not yet reachedDate before it movedWhere the date was before it movedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2025 (actual). Primary completion is estimated for May 2027, 25 months after the start.

Of 27 interventional studies with no phase under Dilatation, Pathologic, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 37. This study's planned 25 months is close to that.

Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 13, 2026: primary completion Aug 2026 → May 2027 and completion Jul 2027 → Dec 2027.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
