Study summary

The goal of this retrospective cohort study is to learn about wether the gender of the anesthetist affects time to epidural anesthesia (EDA) for laboring women . The main questions it aims to answer are:

  1. Is there a gender difference in time to applying EDA
  2. What is the mean waiting for EDA in laboring women in Sweden

Participants (anesthesiologists) will be reviewed according to the time from when the midwife asks for EDA to anesthesiologist register that it was in place

Read the detailed description

In certain hospital in Sweden, a module on the most contemporary Obstetric chart system in Sweden allows for registration of time from request of EDA to applied EDA.Time of request is made by the midwife and the Tim of application is registered by the anesthesiologist. Not all hospitals makes these registrations, thus only (i)hospitals having this module and (ii) hospitals willing to participate will be included.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar 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 Jan 2023 (actual). Primary completion is estimated for Jun 2023, 5 months after the start.

Of 31 non-industry observational studies under Labor Pain, half reached primary completion within 9 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 32. This study's planned 5 months is below that.

Counting every sponsor, half of 32 studies reached it within 9 months; a quarter within 6 and three quarters within 32.

How these figures are worked out, and which studies are left out of them.

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.
No changes since tracking began. The registry record was last updated on Feb 27, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
