Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this research study is to develop a method of rating videos of CAB procedures that will produce a reliable assessment of a cardiothoracic surgical trainee's technical proficiency. In addition, researchers also want to learn if using a video manual to train raters can help improve rater reliability.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Cardiothoracic Surgeon:

If you agree to take part in this study, you will receive a DVD containing multiple videos of different surgeons or surgical trainees performing CAB procedures. You will be trained by the Principal Investigator (PI) on how you should rate the performance of each surgeon/trainee. You will be randomly assigned to 1 of 2 groups:

* If you are in the Conventional Rater (CR) Group, you will receive conventional training from the PI about how to rate the videos.
* If you are in the Video Rater (VR) Group, you will receive conventional training from the PI about how to rate the videos. You will also receive a video rater training manual.

You will receive up to 38 different recorded procedures while you are on study. Each procedure should last about 15 minutes. You will record the identification code that appears at the beginning of each video, and the date and time that you viewed each video. You will watch each video and then rate the performance of the surgeon/trainee using a checklist and a Global Rating Scale. These rating documents will be given to you on a thumb drive that you will either fill out on your computer or print out and fill in by hand. You will be given more detailed instructions on how to fill out the checklist and rating scales by the Principal Investigator (PI).

Your identity will be coded and blinded throughout the study. No identifying information will be directly linked to your responses. Only the video identification numbers and your code number will be used to identify the assessment data. The code key will be stored in a separate computer or thumb drive.

Length of Study:

You will have 1 month to view and rate all videos. You will be contacted 1 time each week by the PI to monitor your progress.

After you have watched and rated all the videos, you will return the videos, your responses (either on the thumb drive or on printed hard-copies), and the video rater training manual (if you are in the VR group) in a pre-paid mailer.

Up to 20 raters may take part in this study.

Cardiothoracic Surgical Trainee:

If you agree to take part in this study, you will fill out a form that asks about your surgical experience. It will also ask about your age, sex, and initials, but these fields are optional.

You will then use the ProXennon Surgical Headlight Camera System (a small camera that is mounted in place directly over a high-intensity light that you wear on your head) to record yourself performing CAB procedures. The main principal investigator (PI) will be present when the system is being used to make sure that it is set up properly and to collect the videos when the procedures are complete. No audio will be recorded. Each video will begin when the dissection of a coronary artery has begun and will end when all manipulation of the anastomosis is complete. You will record at least 6 separate anastomoses, or at least 2-3 procedures.

The time taken to set-up the recording equipment will be documented by the PI for each procedure. After each procedure, a questionnaire will be completed by the intra-operative personnel (nurses, anesthesiologist, perfusionist, operative surgeon, assistant surgeon) that contains questions about any interference from the recording equipment. Neither you nor the intra-operative personnel will be identified in this questionnaire.

The videos will be given a code number. The code key will be kept separately from the video recordings. No identifying information will be directly linked to your videos. Only the researcher in charge will have access to the code key. This is so the researcher will be able to link the videos to the form you filled out at the beginning of the study describing your surgical experience. All data will be presented in aggregate to protect participant identity.

Length of Study:

Your participation in this study will be over after you have submitted your last recording

This is an investigational study. The ProXennon Surgical Headlight Camera System is an approved, standard method of recording CAB procedures.

Up to 22 trainees and up to 8 experienced surgeons may take part in this study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Conventional Rater (CR)

CR Group receives conventional training from PI about how to rate coronary artery bypass (CAB) videos.

Surgical Video Assessments

Intervention Type OTHER

Rate performance of the surgeon/trainee in each CAB video performance (5 recorded procedures) using two rating scales, a checklist and the Global Rating Scale. Up to 38 different recorded procedures rated while on the study, each procedure lasting about 15 minutes.

Video Rater (VR)

VR Group receives conventional training from PI about how to rate CAB videos, along with a video rater training manual.

Surgical Video Assessments

Intervention Type OTHER

Rate performance of the surgeon/trainee in each CAB video performance (5 recorded procedures) using two rating scales, a checklist and the Global Rating Scale. Up to 38 different recorded procedures rated while on the study, each procedure lasting about 15 minutes.

CAB Recording

CAB recording of performance cardiothoracic surgeon or surgical trainee in 1st, 2nd, or 3rd year of training.

Video Recording of CAB

Intervention Type OTHER

Each video begins when dissection of a coronary artery has begun and ends when all manipulation of anastomosis is complete. At least 6 separate anastomoses will be recorded, or at least 2-3 procedures. A ProXennon Surgical Headlight Camera System (a small camera that is mounted in place directly over a high-intensity light that is worn on the head) records the performance of the coronary artery bypass (CAB) procedures.
