Randomized Controlled Evaluation of Robotic Cardiac Surgery Training Modalities

November 2, 2018 updated by: Lawson Health Research Institute
The purpose of this research is to objectively compare various training modalities currently available in minimally invasive and robotic surgery to determine the most effective training methods specific to robotic cardiac surgery. We hope to recruit medical trainees with minimal robotic surgery training experience, randomly assigned to one of three groups (Dry wab, da Vinci Simulator and Wet lab). Trainees will be evaluated at baseline for a standardized tasks common in robotic cardiac surgery and then divided into one of the three training modalities. Trainees will be given sufficient time to become proficient with a variety of predetermined tasks unique to each training group. The trainees will then undergo a reevaluation with the cardiac surgery specific tasks at the end of a standard training period. We will then be able to compare our three groups to show if any have benefits over the others in regards to improvement in technical ability, understanding of the robots functions, efficacy of training, speed of technical skill development, accuracy and efficiency of movement. We will rate each modality on their reproducibility, accuracy of representation, and ease of set up and perform a cost analysis for each of the training methods.

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

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

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.
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.
Active Comparator: Wet Lab
Subjects in the wet lab group will perform dissections of the internal thoracic artery and placement of annuloplasty stitches in the mitral valve in pig models until time proficiency is reached based on the performance of our expert robotic surgeons.
Other: Wet Lab
ITA dissection and Annuloplasty Sutures in porcine model.
Active Comparator: Dry Lab
Subjects in the dry lab group will perform exercises form the fundamentals of laparoscopic surgery (FLS) program adapted for the daVinci robot. These exercises included, camera and clutching, peg transfer and intracorporeal knot tying. Participants will repeat these tasks until time proficiency is reached based on the performance of our expert robotic surgeons.
Other: Dry Lab
Camera and clutching, peg transferring, intracorporeal knot tying
Active Comparator: Virtual Reality
Subjects in the virtual reality group will perform exercises from a 9 task curriculum, on the daVinci Skills Simulator. These exercises included, camera and clutching, energy switching, peg board, energy dissection, matchboard, ringwalk, suture sponge, and vertical defect suturing. Participants will repeat these tasks all metrics are passed and an overall score is reached based on the performance of our expert robotic surgeons.
Other: Virtual Reality
daVinci Surgical Skills simulation
No Intervention: Control
The control group will receive no training after they complete the initial assessment and undergo randomization. They will be invited back after several weeks to complete the final assessment to control for any improvement in performance from the initial assessment alone and normal progression through surgical training outside of this project.

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
Time to Complete Mitral Valve Annuloplasty
Time Frame: 3 months
A total score for this task will be generated from the formula; Score = 720 - Time(s), If any damage is done to the tissues a score of zero will be assessed.
3 months
Time To Complete 10cm dissection of the Internal Thoracic Artery
Time Frame: 3 months
A total score for this task will be generated from the formula; Score = 1320 - Time(s), If any damage is done to the tissues a score of zero will be assessed.
3 months
Global Evaluative Assessment of Robotic Skills (GEARS) Score
Time Frame: 3 Months
A validated objective scoring tool will be used to evaluate overall robotic surgical skill for each task.
3 Months

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.
