Overview
This study aimed to develop evaluation criteria for intraoperative camera devices and their video output due to the lack of reliable technology for capturing high-quality video during open surgical procedures. The researchers employed a modified Delphi process, involving two iterative surveys with expert surgeons experienced in intraoperative video capture. This process resulted in the creation of two evaluation instruments: one for assessing the user experience (UX) of intraoperative camera devices and another for evaluating video quality (VQE).
The study identified 10 key factors for the UX survey and 6 factors for the VQE survey, all meeting an agreement threshold of over 80% among participating experts. These factors encompass various aspects such as ease of setup, comfort, device integration, video quality metrics, and overall user satisfaction. The resulting evaluation instruments provide a standardized means to critically assess camera technologies for capturing intraoperative video during open surgery, addressing a significant need in the field.
Results
Eighty-six experts participated in the first iteration of the survey and 46 in the second. Ten factors met the a priori cutoff for >80% agreement for the UX survey: (1) ease of setup/integration with current practice, (2) comfort, (3) distracting during case, (4) overall satisfaction with wearing the device, (5) would you use this device again, (6) would you recommend this device to colleagues, (7) the weight of wearing the device, (8) sufficient battery life, (9) ability to control device while operating, and (10) degree to which the device interferes or is incompatible with other surgical accessories. Six factors met the cutoff for the VQE survey: (1) camera stability, (2) brightness/exposure, (3) resolution/sharpness, (4) unobstructed view of the surgical field, (5) appropriate field of view, and (6) overall satisfaction with video quality.
