Fun and Games: Designing a Gamified Central Venous Catheterization Training Simulator

Gamification, or adding elements of games to training systems, has the potential to increase learner engagement and information retention. However, the use of gamification has yet to be explored in Central Venous Catheterization (CVC) trainers which teach a commonly performed medical procedure with high incidence rates. In order to combat these errors, a Dynamic Haptic Robotic Trainer (DHRT) was developed, which focuses on vessel identification and access. A DHRT+ system is currently under development that focuses on whole procedure training (e.g. sterilization and catheter insertion), including a gamified Graphical User Interface. The goal of this paper was to (1) develop a game-like, patient-centered interface to foster personalized learning and (2) understand the perceived utility of gamification for CVC skill development with expert doctors. This paper outlines some of the potential benefits and deficits of the use of gamification in medical trainers that can be used to drive simulation design.

Venous Catheterization

Central venous catheterization (CVC) is a medical procedure where a surgeon attempts to place a catheter in the jugular, subclavian, or femoral vein. While useful, this procedure places patients at risk of a wide variety of adverse effects. Traditionally, training is performed on CVC mannequins, but these mannequins cannot vary patient anatomy. This work describes the development of a mobile training platform utilizing a haptic robotic arm and electromagnetic tracker to simulate a CVC needle insertion. A haptic robotic arm with custom syringe attachment used force feedback to provide the feeling of a needle insertion. A virtual ultrasound environment was created and made navigable by a mock ultrasound probe containing a magnetic tracking device. The effectiveness of the system as a training tool was tested on 12 medical students without CVC experience. An average increase in successful first insertion of 4.2% per practice scenario was seen in students who trained exclusively on the robotic training device. The robotic training device was able to successfully vary the difficulty of the virtual patient scenarios which in turn affected the success rates of the medical students. These results show that this system has the potential to successfully train medical residents for future CVC insertions.

Venous Catheterization

Central venous catheterization is a common diagnostic and therapeutic procedure in modern clinical practice. Pseudoaneurysms of the subclavian artery are rare and usually occur immediately after the causative event, whether the cause was trauma or a medical procedure. Here, we report a case of a 71-year-old woman with delayed presentation of catheter-related subclavian pseudoaneurysm. The patient’s symptoms began two weeks after the initial catheterization, probably because of slow leakage of blood from the injured subclavian artery caused by incomplete compression of the puncture site and uremic coagulopathy. She was successfully treated with ultrasound-guided thrombin and angiography-guided histoacryl injection without stent insertion or surgery.

Abstract A concept for a sensorized medical tray in conjunction with real-time visual cues to aid medical residents in learning the steps of complicated tray-based medical procedures, such as central venous catheterization, was designed and tested as a first iteration. This paper outlines the selection of an LED screen to illuminate various medical devices and the testing of simple magnetic reed switches to use as sensors to track the movement of various medical tools from a tray. While this concept was designed around central venous catheterization, this work is translatable to any medical procedure using a pre-packaged plastic tray.

Automated Feedback

The Dynamic Haptic Robotic Trainer (DHRT) was developed to minimize the up to 39% of adverse effects experienced by patients during Central Venous Catheterization (CVC) by standardizing CVC training, and provide automated assessments of performance. Specifically, this system was developed to replace manikin trainers that only simulate one patient anatomy and require a trained preceptor to evaluate the trainees’ performance. While the DHRT system provides automated feedback, the utility of this system with real-world scenarios and expertise has yet to be thoroughly investigated. Thus, the current study was developed to determine the validity of the current objective assessment metrics incorporated in the DHRT system through expert interviews. The main findings from this study are that experts do agree on perceptions of patient case difficulty, and that characterizations of patient case difficulty is based on anatomical characteristics, multiple needle insertions, and prior catheterization.
