Study summary

All physicians, nurses, and nurse midwives working on Labor and Delivery will be required to complete cervical exam simulation training. Data before and after institution of the training will be compared to determine if the training leads to less cervical exams during labor and increases consistency between examiners

Read the detailed description

The labor cervical exam is the cornerstone of the management of labor as the accurate assessment of cervical dilation and effacement are crucial in recognizing a normal labor from and abnormal one. To enhance accuracy and precision among healthcare providers working on Labor and Delivery we have created a high fidelity cervical exam simulator. All providers working on Labor and Delivery Repetitive will be required to practice on the simulators until a pre-specified level or accuracy is achieved. We will prospectively and retrospectively assess the number of cervical exams a women receives and the discrepancy between exams performed by 2 different providers both before and after the training is instituted.

Study arms

  • Experimental
    systematic cervical exam training--retrospective measures

    Effects of systematic cervical exam training on Labor and Delivery Care The total number of exams per hour of labor or triage stay and exam discrepancy between 2 examiners who performed exams less than 30 minutes apart will be compared between the 6 month time period before the unit wide training and 6 months after completing training

    Behavioral: cervical exam training

  • Experimental
    systematic cervical exam training--prospective measures

    Effects of systematic cervical exam training on Labor and Delivery care Patient will be approached to obtain consent for them to have 2 cervical exams performed one after the other when an exam is clinically indicated. The discrepancy between the 2 examiners will be compared between the 6 month time period before the unit wide training and 6 months after completion of the training.

    Behavioral: cervical exam training

Interventions

  • Behavioralcervical exam training

    Each nurse will then examine 1 sets of 10 high-fidelity silicone task trainers approximately three per week for a maximum of 20 sessions (200 repetitions total). For each set of 10 exams, the estimates will recorded on an answer sheet. A cumulative summation analysis will be performed on each participant. When an individual nurse achieves competence her training will be suspended

What researchers measure

Primary outcomes

  1. Number of repetitions needed to obtain competence

    The number of simulated cervical exams each provider needs to reach a pre-specified level of accuracy.

    Time frame: 3 month training period

  2. Number of exams patients receive

    Number of exams per hour of labor or triage visit

    Time frame: Six months period before training

  3. Number of exams patients receive

    Number of exams per hour of labor or triage visit

    Time frame: Six month post training

Secondary outcomes

  1. Discrepancy between 2 cervical exam assessments--retrospective

    Discrepancy between 2 exam assessments performed less than 30 minutes apart by 2 different examiners: Cervix Dilation will be reported as 1-10 cm Cervix Effacement will be reported as 0% -100%

    Time frame: Six months period before training and Six months period post training completion

  2. Discrepancy between 2 cervical exam assessments--prospective

    Discrepancy between 2 exam assessments performed one after the other by 2 different examiners: Cervix Dilation will be reported as 1-10 cm Cervix Effacement will be reported as 0% -100%

    Time frame: Six months period before training and Six months period post training completion

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 Jul 2020 (actual). Primary completion is estimated for Dec 2026, 77 months after the start.

Of 18 interventional studies with no phase under Dystocia, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 40. This study's planned 77 months is above that.

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 Jun 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
