About this project

The problem we solve:
We introduce the concept of “cross sectional literacy” as a foundational element that has to be mastered to achieve safety and competency in ultrasound guided medical procedures. It has been well documented that people with low spatial ability have difficulty imagining the cross-sections of 3D objects. The most common error is the egocentric error: the inability to transfer from one’s perspective to the perspective of the cutting plane. To visualize the proper cross-section obtained by an ultrasound probe, one must be able to abandon a “coordinate system” centered on oneself and transpose one’s perspective to the ultrasound probe. This type of thinking is taught in drafting, architecture, and engineering curriculum; therefore we know it can be a learned skill. However, cross sections are not taught in medical school; the first time medical practitioners interpret cross sections that they are generating in real time using an US probe may be on real patients, a sub-optimal situation

About our solution:
We repurposed a transportable, modular simulator we are developing for regional anesthesia to teach basic ultrasound probe manipulation and cross sectional image creation and interpretation. Six degree of freedom trackers in the needle and probe help insonate and needle familiar 3D virtual objects that can be swapped and modified as needed. We use simple, recognizable 3D objects like cones. We purposefully left out anatomy so that learners can focus on cross sectional literacy of familiar objects without having the additional burden of learning anatomy. The curriculum contains tasks of increasing complexity that are designed to build psychomotor ultrasound and needling skills. The simulator contains cognitive aids that define probe orientation so we can teach how to efficiently request specific probe orientations and an aid that shows the insonating plane view of the needle.
Progress to date: We have developed a curriculum in four categories: reading, writing, interpreting, and needling. In the reading exercises, 3D objects are scanned at will. Users then identify the 3D object from a list. Objects increase in complexity and require specific probe manipulations for correct identification. In Writing, learners must acquire given cross sections by properly manipulating the ultrasound probe. Successive problems require complex probe manipulations, like tilt. Other problems require users to apply one degree of freedom at a time, such as rotating the probe while maintaining a target in the center. Even skilled clinicians may learn from these. In the interpretation problem group, emphasis is first placed on sidedness, strategy, and scout scanning, and planning safest needling areas. The simulator includes a tracked needle and a tracked US probe. In-plane, out-of-plane, needle anisotropy and angle of incidence are simulated. https://www.youtube.com/watch?v=BtVzzVqGcHk

How We Help Patients

A recent BMJ paper found medical error as the third leading cause of death in the US (~250,000/yr). We have identified what we believe is a gap in medical education. Imaging devices such as ultrasonography (US) create 2D cross-sections out of 3D objects and organs: lack of formal training in cross-sectional literacy (“reading”: inferring shapes of 3D objects from 2D cross-sections and “writing”: obtaining desired 2D cross-sections out of 3D objects from medical imaging devices such as US probes). We strongly believe that our technology for acquiring and maintaining cross-sectional and ultrasonography literacy will enhance medical education AND will prevent avoidable medical errors such as iatrogenic pneumothorax during central venous access, a Serious Reportable Event (aka as a "never event" that unfortunately happens all too often). By helping to reduce medical errors, our technology can improve patient safety, enhance quality of care and reduce morbidity, thus benefiting patients.

How We Help Education

The advent of medical imaging tools (e.g., ultrasonography (US) that produces 2D cross sections and is becoming widespread and portable) creates a need in medical education for better training in cross sectional literacy, US and spatial skills. Cross sectional literacy, taught in drafting, architecture, and engineering curricula, is not part of medical education curricula. Studies such as Uttal et al 2013 have shown spatial skills can be taught and learned. Furthermore, we believe learning both anatomy and US at the same time when practicing a specific medical procedure will overload true novices. We therefore replace anatomy by familiar 3D objects so novices can focus on US only and not be distracted by irregular anatomy that is, at that point, unfamiliar. We are providing a new, procedure-agnostic trainer to acquire cross sectional literacy and ultrasound skills before medical and other students touch actual patients without the "distraction" of procedure-specific anatomy.

How We Help Physicians

In demonstrating our cross-sectional literacy and ultrasonography (US) trainer at international scientific meetings and workshops, we noticed that cross sectional literacy and US skills vary widely among physicians and veterinarians who used our new trainer. Some physicians were challenged by basic cross-sectional literacy exercises. Others were unable to acquire specific US images (cross-sections) even though they used ultrasonography daily, because they were unaware of all the degrees of freedom of an US probe (the learning objective of that particular exercise). All physicians seemed to appreciate the usefulness of the trainer, including military anesthesiologists who used it on extended loans, in teaching how to use ultrasonography to its full capabilities. To accommodate busy physician schedules, the trainer is turnkey and compact allowing on-site experiential learning so that physicians do not have to travel to a training site. We help physicians by addressing a training gap.

Challenge Mission

Mission: Our solution will support improving the nation’s health by training physicians and healthcare workers in using ultrasonography better and safer, reducing medical errors, the 3rd cause of death in US.
Use of funds: If we receive the first award, we will use the funds to acquire the materials to build with pro bono labor a cross sectional literacy and ultrasonography trainer that we will donate to the AMA or the AMA’s designee so that more physicians can be exposed to the training provided by the simulator. If we receive a different award, we will use the funds to extend the curriculum of the cross sectional literacy and ultrasonography trainer.
Intellectual Property Status: The IP behind a modular set of augmented reality simulators, that includes the cross-sectional and ultrasonography trainer submitted to the AMA contest, is protected by recent US patent 9,251,721 (Lampotang et al, inventors) issued 2/2/2016 to UF.
Patent Link: http://google.com/patents/US9251721
FDA Status: Not applicable. Not a medical device.
Personal Message: We are a small group of engineers and physicians who have been privileged to work on exciting but, more importantly, meaningful projects that have positively impacted patient safety and medical education worldwide. Our simulation lab helped launch the rebirth in the late ‘80s of simulation in healthcare as a training tool though its Human Patient Simulator mannequin. We strongly believe that much good will similarly result from our latest project and humbly request your help by voting for it.
