Study summary

This is a study evaluating the use of the modified beef tongue model for teaching repair of obstetrical fourth-degree laceration to residents. Participants will be randomized to either an instructional video using the modified beef tongue model or to an instructional workshop using the modified beef tongue model. Primary outcome will be measured as change in technical skills score as measured by change from baseline on a validated objective structured assessment of technical skills (OSTATS) for repair of fourth-degree laceration.

Read the detailed description

Institutional Review Board approval has been obtained and written informed consent will be obtained prior to initiation of the study. All obstetrics and gynecology residents at the University of Alabama will be eligible for the study.

Eligible residents who desire will be enrolled and consented for the trial. Participants will then complete a short pre-intervention knowledge assessment written test and be asked to rate their confidence level in completing a fourth-degree repair based on a Likert scale. The written test is the same as the one used by Patel et al to evaluate residents' knowledge about fourth-degree laceration repair. The questions are based on Williams's obstetric chapter on episiotomy repair and showed construct validity given a significant difference in scores between postgraduate year (PGY)-1 and PGY-4 residents. Participants will also complete a baseline objective structured assessment of technical skills (OSATS) assessment for repair of fourth-degree obstetric laceration on a commercial anatomical replica, the Sultan Anal Sphincter Trainer (Limbs \& Things Inc, Savannah, Georgia). This model comes with a replaceable perineal pad that allows approximately 24 repairs before replacement is necessary. The validated OSATS used will be the assessment described by Siddiqui et al and validated on a surgical model. The repair will be videotaped and then distributed to evaluators who will use the 20 item task specific checklist described by Siddiqui et al. The time taken for the repair will be recorded.

Demographic and baseline data will be collected on the participants including PGY level, number of fourth-degree lacerations performed, whether they have read a textbook regarding fourth-degree laceration repair, whether they have read a journal article regarding fourth-degree laceration repair, whether they have attended a didactic session in pelvic anatomy, and whether they have attended a didactic session on fourth-degree laceration repair.

Participants will then be randomized into two groups. Randomization will be performed using a computer-generated block design so that each group has a balanced number of residents in each postgraduate year training level. One group will be randomized to the modified beef tongue video and one will be randomized to the modified beef tongue instructional workshop. The modified beef tongue video group will be given an instructional video created using the modified beef tongue model to show anatomy and proper repair of the laceration. The group randomized to the modified beef tongue instructional workshop will undergo an interactive workshop using the modified beef tongue model to show anatomy and proper repair of the laceration.

The modified beef tongue for the video and workshop will be prepared according to the model previously described in the literature. The modified model includes beef tripe (small intestine) used for anal mucosa and chicken leg muscles for anal sphincter muscle analogs. The tripe is tunneled through the body of the trimmed beef tongue and sutured like an ostomy to simulate the anal canal. The tongue is incised toward the tripe "anal canal." Chicken leg muscles are tunneled from the incision out to the cut edges of the beef tongue to create anal sphincter muscle analogs.

Following the didactic intervention, participants from each group will be given the written knowledge assessment test again and the objective structured assessment of technical skills (OSATS) for repair of fourth-degree laceration on the commercial anatomical replica again. The time taken for the repair will be recorded. Residents will also be asked to evaluate model realism, ease of use, and satisfaction using a Likert scale. The residents will be asked to assess their confidence again using a Likert scale.

The participants will then be crossed over and those who were initially randomized to the video group will then undergo the instructional workshop and the ones initially in the workshop group will be given the instructional video. Participants will then be asked to rate their overall preference between models on a scale of 1 to 10 with 1 being the video and 10 being the instructional workshop. They will also complete the written knowledge test again.

The results of this trial may help to inform to a cost- and time-efficient manner of instruction on the repair of 3rd and 4th degree lacerations. A weakness is that it is unclear whether this will translate to effectiveness at the time of an actual third- and fourth-degree repair.

What researchers measure

Primary outcomes

  1. Technical skills score

    The primary outcome will be change in technical skills score measured as change from baseline in a validated objective structured assessment of technical skills (OSATS) for repair of fourth degree obstetric laceration. This OSATS was described by Siddiqui et al and is based on a task-specific checklist for fourth-degree lacerations and has a maximum score of 20 and minimum score of 0. The higher the score the better the performance.

    Time frame: up to 24 weeks

Secondary outcomes

  1. Participant preference

    Participant preference of model between instructional video and instructional workshop. Participants will be asked to rate their overall preference between models on a scale of 1 to 10 with 1 being the video and 10 being the instructional workshop.

    Time frame: up to 24 weeks

  2. Knowledge assessment

    Knowledge assessed by written test performed pre- and post-intervention. The written test is the same as the one used by Patel et al to evaluate residents' knowledge about fourth-degree laceration repair. The questions are based on Williams's obstetric chapter on episiotomy repair. The test has a minimum score of 0 and maximum score of 17 with a higher score indicating better performance.

    Time frame: up to 24 weeks

  3. Participant confidence

    Participant's confidence in fourth-degree laceration repair as measured by change in confidence score from pre- to post-intervention. This is based on the participant's response to a 10 point Likert scale with 1 being not confident and 10 being completely confident.

    Time frame: up to 24 weeks

  4. Time of repair

    Time taken for repair of fourth degree laceration

    Time frame: up to 24 weeks

  5. Ease of use of model

    Ease of use of the model as reported by participants. This is based on the participant's response to a 10 point Likert scale with 1 being not easy and 10 being the easiest.

    Time frame: up to 24 weeks

  6. Satisfaction

    Overall satisfaction of each model as reported by participants. This is based on the participant's response to a 10 point Likert scale with 1 being not satisfied and 10 being completely satisfied.

    Time frame: up to 24 weeks

  7. Model realism

    Model realism as reported by participants. This is based on the participant's response to a 10 point Likert scale with 1 being not realistic and 10 being the most realistic.

    Time frame: up to 24 weeks

  8. Factors associated with higher knowledge scores

    Factors associated with higher knowledge scores (e.g. PGY level, number of prior repairs, prior didactics). The written test is the same as the one used by Patel et al to evaluate residents' knowledge about fourth-degree laceration repair. The questions are based on Williams's obstetric chapter on episiotomy repair. The test has a minimum score of 0 and maximum score of 17 with a higher score indicating better performance.

    Time frame: up to 24 weeks

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

Ran from Nov 2017 to primary completion in Mar 2018, 4 months.

Of 547 non-industry interventional studies with no phase under Wounds and Injuries, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 49. This study's 4 months is below that.

Counting every sponsor, half of 600 studies reached it within 24 months; a quarter within 9 and three quarters within 48.

Wounds and Injuries covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

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 Apr 18, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
