The Success of Labor Induction Based on a Modified BISHOP Score.

Study Overview
=================
Brief Summary
-----------------
Pregnant women at term will be divided randomly into 3 groups: Gynecological evaluation based on classic BISHOP score. Gynecological evaluation based on a modified BISHOP score. Gynecological evaluation based on cervical length as measured by transvaginal sonography. After gynecological evaluation, women will undergo induction of labor based on obstetric evaluation according to the group they were part of.

Detailed Description
-----------------
Women presenting to the obstetric emergency room for follow-up for various obstetric/other medical conditions over 37 weeks' gestation that are candidates for labor induction will receive an explanation regarding the study and sign informed consent. The women will be divided randomly into 3 groups: Gynecological evaluation based on classic BISHOP score. Gynecological evaluation based on a modified BISHOP score. Gynecological evaluation based on cervical length as measured by transvaginal sonography. After gynecological evaluation, women will undergo induction of labor based on obstetric evaluation according to the group they were part of.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Classic BISHOP score<br>Gynecological evaluation based on vaginal examination including cervical dilatation, effacement, texture, station and position. | Diagnostic Test: Vaginal examination.<br>* Cervical properties as evaluated by a vaginal examination.<br>|
| Modified BISHOP score<br>Gynecological evaluation based on vaginal examination including cervical dilatation and effacement alone. | Diagnostic Test: Vaginal examination.<br>* Cervical properties as evaluated by a vaginal examination.<br>|
| Cervical Length<br>Gynecological evaluation based on cervical length measured by transvaginal sonography. | Diagnostic Test: Transvaginal sonography.<br>* Cervical length as evaluated by a transvaginal sonography.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to delivery | The time from induction commencement to delivery of the newborn. | Up to 72 hours. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| BISHOP score after primary induction. | BISHOP score after primary induction. BISHOP is not an abbreviation and is just the name of the score. The minimum score is 0 and the maximum score is 13. The higher the score, the more favorable the cervix is considered before induction of labor. | Up to 24 hours. |
