- Brief Summary
This study evaluates the impact of video communication via telemedicine on the quality of emergency care provided to children by paramedic teams supported by a remote physician in a simulated out-of-hospital setting. Half of the paramedic teams will use a video telemedicine platform for communication with a physician, while the other half will use an audio-only platform.
- Detailed Description
In the United States, the current standard of pre-hospital (out-of-hospital) emergency care for children with life-threatening illnesses in the community includes remote physician medical direction for paramedics providing life-saving therapies while transporting the child to the hospital. Most pre-hospital emergency medical service (EMS) agencies use radios systems for audio communication between paramedics and physicians. This communication strategy is inherently limited as the remote physician cannot visualize the patient for accurate assessment and to direct treatment.
The purpose of this pilot study is to evaluate whether use of a 2-way audiovisual connection with a pediatric emergency medicine expert (intervention = "telemedical support") will improve the quality of care provided by paramedics to infant simulator mannequins with life-threatening illnesses. Paramedics receiving real-time telemedical support by a pediatric expert may provide better care due to decreased cognitive burden, critical action checking, protocol verification, and error correction.
Because real pediatric life-threatening illnesses are rare, high-stakes events and involve a vulnerable population (children), this pilot randomized control trial will provide early data on the efficacy of this intervention in simulated cases of pediatric medical emergencies. The primary outcome is "paramedic resuscitation performance" measured by a checklist of observable critical actions by independent reviewers during live observation and video review. The results of this study will provide important pilot data to estimate the clinical effect of this intervention and the sample size needed for a future definitive trial with children, a vulnerable population.

- Primary Outcome Measures
Name Time Method Paramedic Team Performance score 9 months The paramedic team performance score is generated from a 64-item checklist of observable actions for pediatric assessment and resuscitation that are scored dichotomously (observed/not observed). The composite performance score is calculated as the number of observed actions divided by the total number of expected actions per case, and reported as a percentage of completed observed actions. This checklist is validated for simulation-based assessment of paramedic performance using three simulated cases of pediatric pre-hospital emergencies. Paramedic team performance will be rated by 1 live and 2 video raters. The final performance score for each team will be reported as an average score for all three raters.
- Secondary Outcome Measures
Name Time Method Error in medication choice 9 months This will be any incorrect type of medication utilized by a team during each simulation resuscitation. This includes unanticipated medication choices which the study raters feel was not indicated or potentially harmful by consensus opinion. This data is collected in the paramedic performance checklist.
Telemedicine Platform Usability 9 months This 14-item questionnaire is a validated measure of all the usability of telehealth platforms (usefulness, ease of use, effectiveness, reliability, and satisfaction). The investigators modified this questionnaire to specifically address the usability of a prehospital telemedicine platform. Study participants will complete this questionnaire immediately after completing the simulation modules.
Equipment use errors 9 months This includes errors in equipment usage (e.g. depth of endotracheal tube insertion, rate of bag-valve-mask ventilation, location of intraosseous needle insertion) during each simulated resuscitation. This data is collected in the paramedic performance checklist.
EMS protocol error 9 months This will be defined as any error in offline and online EMS treatment protocols that is observed during each simulated resuscitation. This data is collected in the paramedic performance checklist.
NASA Task load Index 9 months This is an extensively validated measure of perceived workload of individuals. It is a multidimensional scale where individuals estimate workload during or after completing a task. It contains 7 domains (mental demand, physical demand, temporal demand, performance, effort, frustration, and anxiety) which are evaluated on a 20-point Likert scale. Study participants will complete this questionnaire immediately after completing the simulation modules.
Error in weight-based medication dosing 9 months This will include any errors in pediatric weight-based dose calculation, including errors in volume of drug administered during each simulated case. This data is collected in the paramedic performance checklist.
Equipment size error 9 months This includes errors in equipment size during each simulated resuscitation. This data is collected in the paramedic performance checklist.
