Augmenting the On-Scene Medic (ATOM): A Randomized, Controlled, Multicenter Study to Assess the Effectiveness of Augmented Reality Software on Prehospital Pediatric Medication Administration Accuracy
Augmenting the On-Scene Medic (ATOM): A Randomized, Controlled, Multicenter Study to Assess the Effectiveness of Augmented Reality Software on Prehospital Pediatric Medication Administration Accuracy
The primary objective of this research study is to use simulated pediatric emergencies to test the effectiveness of a drug dosing safety system for EMS providers by comparing usual care to use of an augmented reality device.
The objective of this project is to develop a safe and effective dynamic cognitive aid application for use through a head-mounted display (HMD), to reduce error rates associated with pediatric medication administration (PMA) by emergency medical services (EMS). This objective will be achieved by examining characteristics associated with PMA, using a design thinking process to develop a prototype application, examining usability of the prototype, and testing the safety and efficacy in a randomized controlled trial.
Errors associated with PMA in EMS are alarmingly high. Numerous studies have shown that there is a 31% error rate across all drugs administered to children by EMS. Medications such as midazolam and fentanyl have even higher rates at 61% and 65%, respectfully, with many being 10-fold errors. Sadly, previous strategies have had little impact on reducing error rates below 31%. System changes have failed due to inconsistencies in EMS systems, and challenges associated with medication shortages. Previously developed cognitive aids have fallen short often due to the fact they generally act as simple reference tools and do not address all causes of error associated with PMA. As a result, we are proposing the most comprehensive design process ever taken to combat this issue, utilizing advanced technology, to implement a dynamic cognitive aid to help providers improve dosing accuracy during PMA.
We hypothesize that PMA errors in EMS will be significantly reduced by this application due to the comprehensive and rigorous design thinking process we will utilize followed by a randomized controlled trial to test safety and efficacy. Our interdisciplinary team will combine the fields of pediatric emergency medicine, EMS, engineering, computer science and user interface/user experience to address this issue with the support and effort of two medical schools in Michigan. In SA1 we will develop a prototype application. This will begin with identifying user and contextual information associated with PMA, and examine failure modes, root causes, and a task analysis of the procedure. We will then proceed into a comprehensive design thinking process to develop the application. During this process we will also create a desktop program that will allow EMS agency administrators to add new medications to the HMD application. In SA2, we will examine usability of the HMD application and associated desktop program in a simulation-based environment with a sample of end users, examining task duration, cognitive load and error rates and make any necessary refinements. In SA3, we will test the HMD application in a simulation-based randomized controlled trial to examine its safety and efficacy for use in EMS. This will result in a safe and effective tool to mitigate this alarming issue in the vulnerable EMS pediatric population.
