Outcomes in Simulated Endoscopy Training

July 28, 2026 updated by: University of Oklahoma

Simbionix GI Mentor Simulated Endoscopy Training

Eligible participants are those who are members of the general surgery residency pediatric gastroenterology fellowship, and adult gastroenterology fellowship. Through a randomized-controlled trial, participants will fill out a baseline set of demographic information including year of training, approximate number of colonoscopies to date, specialty, age, sex and handedness. Participation in this activity is completely voluntary. Trainees will be randomized to one of two groups. Either first participating in an unassisted colonoscopy module twice and then taking a questionnaire and then transitioning to a supervised/coached colonoscopy module session twice and taking a questionnaire, versus the reverse, in which the participant first partakes in a supervised/coached colonoscopy module session twice and then transitions to performing a colonoscopy module twice, unassisted. Objective measures will be assessed by the module software and supervising faculty. Specifically, using individuals' survey responses to see if early supervision improves survey scores. Survey questions focus on student learning, completing module objectives and faculty performance in simulation. The survey will also ask subjects to self-rate their scores and comfort level with endoscopy skills. Survey responses will not be linked to an individuals' performance in their program training and endoscopy coaches will not be made aware of the survey responses.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This will be a randomized controlled trial in which eligible participants will be members of the general surgery residency and adult gastroenterology fellowship. Investigators will ask all consenting participants to fill out a baseline set of demographic information including their year of training, the approximate number of colonoscopies to date, specialty, age, sex and dominant-handedness. Additional questions to be asked will inquire about the participant's experience in regard to the unassisted and supervision/coached colonoscopy module experience. Participation in this activity is completely voluntary, and the participating trainee is under no obligation to complete or finish the simulation or subsequent surveys The participant will be randomized to one of two groups. A computer program will make this random assignment. Neither the participant nor their physician coach will be able to choose which group they will be in. Participants will either first partake in an unassisted colonoscopy module twice (case one and case two) and then transition to a supervised/coached colonoscopy module session twice (case three and case four). The alternative is in which the participant first partakes in a supervised/coached colonoscopy module session twice (case one and case two) and then transitions to performing an unassisted colonoscopy module twice (case three and case four). A questionnaire examining training experience will be administered after case # 4 in both groups. This survey will take approximately 5 minutes to complete. Other objective measures will be assessed by supervising faculty and other metrics acquired through the simulator software. Individuals' survey responses will be used to see if early supervision improves trainee satisfaction and perceptions on survey scores. Participants will attend one individual training session date that will satisfy the designed simulation experience. The trainee can stop participating in this study at any time and participation in the study is voluntary and trainees may choose not to participate. It is important to note that refusal to participate will not affect a learner's access to the training center and will not affect their standing in their respective training program. The results will not be included in their official training record. Note no prior procedural or technical knowledge is required. Enrollment will continue for the 2018-2019 academic year and possibly academic years thereafter.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
50

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

22 years to 50 years (Adult)

Accepts Healthy Volunteers

Yes

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of mucosa inspected
Time Frame: through study completion, an average of 1 year
The primary outcome will be the difference in percentage of mucosa inspected between the two study groups based on the report of the simulator after each of 4 predefined cases
through study completion, an average of 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
