About this study

A study to determine whether completing a rigorous simulation protocol could provide novice robotic surgeons with actual advanced surgical skills in an operating room setting.

Read the detailed description

Objective: To determine whether a group of surgeons otherwise naive to robotic techniques could demonstrate proficiency during their first robotic supracervical hysterectomy having only received simulator and pig lab training.

Primary outcome measure: As measured by time spent on the surgeon console from beginning of hysterectomy until the end of cervical amputation.

Secondary Outcome measures:

  1. Blood loss- as measured by the blood suctioned into the canister throughout the hysterectomy and at the end of the amputation discounting irrigation volume.
  2. Surgical skill rating- All procedures will be recorded and rated by a blinded investigator according to a standardized surgical skills evaluation sheet.
  3. Surgeon console biometrics- As measured by controller movements and grips
  4. Novice robotic surgeon data: Descriptive Operative data of surgeons who did not participate in robotic simulator training.

Methods: To create the simulator protocol, 5 robotic surgeons (each averaging >75 robotic cases per year) performed all 28 simulation modules available on the da Vinci Skills Simulator. To establish "expert benchmarks", they picked the 10 simulator modules they thought were most beneficial to robotic novices', and they performed each of these 10 modules to the best of their ability >5 times. The data was used to create benchmarks in which all parameters of these 10 modules were taken into account (i.e. not just the time to completion). Thus the "Morristown Protocol" was established- whereby successful completion of the protocol required passing every parameter of all 10 simulator modules at the expert level.

We then recruited community board-certified OB-GYN's who were completely naive to robotics and offered them full robotic training free-of-charge as long as they could pass the "Morristown Protocol" as their very first step in the training process. These "study surgeons" were given 24/7 access to the da Vinci Skills Simulator and simply asked to complete the protocol at their own pace. Within a week of doing so, they went through the standardized Intuitive Surgical pig lab and then performed their first ever robotic surgery- a supracervical hysterectomy- as our main outcome measure. These cases were performed using the dual-console daVinci system with one of the senior authors on the other console ready to step in if necessary.

Two sets of comparative benchmarks for this surgical procedure has been established. Our "expert surgeons" each performed supracervical hysterectomies for the study- as did a group of "control surgeons". These "control surgeons" had full robotic privileges but were not averaging more than 2 cases per month and had never used the simulator. Operative time, EBL, and a blinded skill assessment (of videos) were compared for all cases among the 3 surgeon groups using t-tests.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Surgical Time

    As measured by time spent on the surgeon console from beginning of hysterectomy until the end of cervical amputation

    Measured: At end of cervical amputation

Secondary outcomes (4)
  1. Blood Loss

    As measured by the blood suctioned into the canister throughout the hysterectomy and at the end of the amputation discounting irrigation volume

    Measured: End of cervical amputation

  2. Surgical Skill Rating

    All procedures will be recorded and rated by a blinded investigator according to a standardized surgical skills evaluation sheet

    Measured: Within a month of the performed surgery

  3. Surgeon Console Biometrics

    As measured by controller movements and grip

    Measured: during surgery

  4. Novice Robotic Surgeon Data

    Descriptive Operative data of surgeons who did not participate in robotic simulator training

    Measured: Within a month of the performed surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Pelvic Organ Prolapse, run by Atlantic Health System at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Surgical Time (time frame: At end of cervical amputation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jun 2017.
