Episode details:

Mr. Gil Spitz was originally a classical musician and shifted his focus to ergonomics and preventative exercise to help musicians with repetitive motion injuries. He furthered his expertise with an MS in Exercise Physiology, researching optimized training for first responders. In 2019, he joined the Medical ICU team at Baylor/St. Luke's Medical Center, developing and enacting exercise plans for medically compromised patients. Since 2021, he has been with the Liver Transplant Program, implementing a hospital-wide method for assessing transplant patients' physical suitability, providing post-transplant follow-up, and developing a virtual pre-habilitation program to improve outcomes.

During this time he has also worked with the surgical staff helping them prevent musculoskeletal and repetitive motion injuries. Gil has worked with providers both on a 1-on-1 basis, addressing specific needs and issues, as well as presenting the topic of OR ergonomics, inter- & intra-op preventative exercises to incoming resident cohorts during an annual bootcamp at Baylor College of Medicine.

In this episode Mr. Spitz:

- Describes his journey from being a musician playing classical guitar to then building a career as an exercise physiologist

- Explains why he likens surgeons to elite athletes, except that little attention is paid to surgeons' recovery period

- Emphasizes that surgeons need to pay attention to their sleep hygiene, address inflammation, evaluation by a functional movement specialist (or a PT/OT) to assess muscle imbalances and passive to active stretching

- Advises surgeons to prioritize their physical health and protect their investment (time, money and effort spent on training and working on their craft)

- Discusses the differences between male and female athletes with respect to strength, mobility and prolonged static tasks and how athlete training programs are actually designed around their menstrual cycles

- Shares emerging research in the area of exercise physiology with respect to exercising with blood flow restriction

Dr. Donny W. Suh a Professor and Chief of Pediatric Ophthalmology and the Eye Mobile Program at the University of California, Irvine. He works at UCI Gavin Herbert Eye Institute and the Children’s Hospital of Orange County (CHOC). He also volunteers with ORBIS Global Health Programs, providing medical care and training ophthalmologists in underserved regions across South America, Europe, Asia, and Africa. In addition, he is the Chair of the American Academy of Pediatrics Ophthalmology Section Membership Committee , an inductee of the American Ophthalmological Society and was awarded “Inventor of the Year” in 2019 by the University of Nebraska Medical Center.

In this episode Dr. Suh:

- Shares that he became interested in ergonomics about 10-15 years into his practice because he started to have MSK symptoms and noticed many colleagyes with the same due to awkward posture while operating

- Explains that loupes are essentially telescopes and that there are 2 main types, Galilean and Keplerian. The former have a convex and concave lens and the latter contain 2 or more convex lenses. Keplerian loupes are able to provide higher magnifications but are heavy due to the higher number of lenses.

- Elaborates on why the use of loupes is an independent risk factor for the development of work-related MSK symptoms among surgeons and dentists.

- Clarifies that here has't been a lot of change in loupe design until very recently, with the major change being prism deflection. Other changes include lighter titanium frames, plastic lenses and strap design.

- Discusses the difference between Galilean and Prismatic loupes. The former are limited by the extent of how deep a declination angle one can achieve. Deflection loupes are technically a subtype of Prismatic loupes but for all practical purposes, they can be considered similar.

- Explains why Prismatic/Deflection loupes need customization (to our face and working distance) or the image will be blurred. Therefore, it is important to simulate your surgical experience when getting fitted for them.

- Advises individuals that there are some challenges associated with using Prismatic/ Deflection loupes, such as image displacement and image distortion, and it is important to give time to get used to working with them

In this episode Dr. Trbovich:

- Shares her training background and how she arrived at her current role

- Defines cognitive ergonomics as a branch of Human Factors that focuses on how we design systems to support the way people think, the way they make decisions and how they manage information, especially under pressure

- Describes the consequences of not paying attention to workers' cognitive ergonomics in the OR, such as, creating conditions where they are overloaded and forced into task-switching (often mistaken for multi-tasking) which then increases the risk of errors

- Discusses her work where her team have identified the most interrupted time for anesthesiologists (i.e. emergence) and nurses (i.e. closing counts)

- Elaborates on the OR black box and other tools (surveys such as the NASA-Task Load Index, observations, objective measures of physiologic responses and behavior markers) that are used to study interruptions and understand work as it is done, and not as it is imagined

- Shares Black box data is useful to look at not only safety threats but also resilience supports and psychological safety.....

- Discusses strategies for preserving cognitive bandwidth of various team members in the OR e.g. calling out increasing cognitive load prior to it reaching a critical point, using checklists and other visual indicators and looking at how often staff are task-switching
