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

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.
