Developing a Deliberate Practice Intervention to Recalibrate Physician Heuristics in Trauma Triage

Study Overview
=================
Brief Summary
-----------------
The objective of this study is to test the feasibility of using deliberate practice - goal-oriented training in the presence of a coach who can provide personalized, immediate feedback - to increase engagement. The research design involves recruitment of a national convenience sample of board-certified emergency physicians who will serve as trainees (n=30), pairing of the trainees with a coach, delivery of three 30-minute coaching sessions using the existing games as the training task, and assessment of the effect of the combined intervention on performance in the laboratory. The specific aims are: To assess the fidelity of intervention delivery by measuring coaching skill acquisition, coaching skill drift and protocol adherence. To assess the potential effect size of the intervention by comparing trainee performance on a validated virtual simulation with a control group of physicians (n=30). To assess the acceptability of the intervention by using a mixture of validated instruments and semi-structured debriefing interviews with trainees to assess their engagement with the intervention.

Detailed Description
-----------------
Deliberate practice - goal-oriented training in the presence of a coach who can provide personalized, immediate feedback - has successfully improved performance across multiple domains, including sports, music, and combat. When used in conjunction with simulation to improve surgical skill, it has a large effect on educational outcomes. It has characteristics that make its application in this context potentially powerful (e.g. personalized feedback/relationship with coach increase engagement) but also potentially challenging (e.g. the diagnostic process does not lend itself easily to assessment). The objective of this study is to test the feasibility of using deliberate practice to amplify the effect of a video game intervention. The team will recruit a national sample of board-certified emergency physicians (n=30) to serve as trainees, with members of the team (n=3) serving as coaches. Trainee-coach dyads will meet for 30 minutes/week for 3 weeks, by video-conferencing, to play one of the existing video games and to use it to practice pattern recognition. Aims are: To assess the fidelity of intervention delivery. Approach: the team will standardize coaching skill during an 'on-boarding session,' measure skill drift over the course of training sessions, and measure protocol adherence (primary outcome). Hypothesis: >90% of dyads will complete three training sessions. To assess the potential effect size of the intervention. Approach: the team will compare performance of trainees (n=30) with a control group of physicians (n=30) on a validated virtual simulation. Hypothesis: Trainees will make ≥25% fewer diagnostic errors than control physicians (large effect size). To assess the acceptability of the intervention. Approach: the team will conduct semi-structured debriefing interviews with trainees, assessing elements of the intervention that promote engagement. This proposal will inform a future Stage III trial to compare the effect of different interventions on diagnostic error in trauma triage. If successful, this program of research will have an impact on patients by reducing the burden imposed by injury and by addressing the refractory problem of diagnostic error. It is novel conceptually in its effort to make heuristics a source of power, methodologically in its use of deliberate practice to improve diagnosis, and translationally in its use of video game technology. It is feasible because the investigative team has clinical and behavioral science expertise, experience developing deliberate practice interventions, and a track record of successfully building video games that can transform physician behavior. It responds to two national research priorities: 1) improving the diagnostic process; 2) maintaining health and independent living among the aging.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: two arm randomized trial
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Deliberate practice<br>Trainees will be paired with a coach, and will meet, once per week for thirty minutes, over a three week period. During the training session, coach-trainee dyads will play a puzzle video game, and will discuss contextual cues that should inform triage decisions. At the completion of the three weeks, trainees will complete a semi-structured, debriefing interview and a virtual simulation to assess triage performance. | Behavioral: Deliberate practice<br>* As above<br>|
| No Intervention: Control<br>Participants in the control group will complete a virtual simulation. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Who Signed up for the Intervention That Completed All 3 Coaching Sessions. | A summary of the number of trainees who signed up for coaching sessions and completed all three sessions as assigned. | 3 week intervention period | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Under-triage | Proportion of severely injured patients NOT transferred to trauma centers/total number of severely injured patients evaluated during a validated virtual simulation | 3 weeks post-intervention (deliberate practice) or 3 weeks post-enrollment (control) | 
| Number of Participants Who Describe Coaching as Acceptable. | Derived from semi-structured interviews conducted by members of the investigative team at the conclusion of the 3 week training period. These interviews will focus on participant perceptions of the acceptability of the intervention. | 2- weeks post intervention |
