简要总结
The goal of this study was to learn whether the MCIPHER memory aid could help first-year resident doctors manage a simulated mass-casualty incident. MCIPHER organizes the response into five phases: command, triage, treatment, transport, and closure.
Twenty-five postgraduate year-1 residents from emergency medicine, trauma surgery, general surgery, and anaesthesiology took part. All participants completed the same two-week course on mass-casualty incident response. Researchers then placed participants into one of two groups using a non-random method. The control group completed a three-dimensional tabletop simulation after the standard course. The MCIPHER group received an additional structured briefing on MCIPHER immediately before completing the same simulation.
The main questions were:
Did MCIPHER affect overall team performance? Did MCIPHER affect how quickly teams completed key actions? Did MCIPHER affect how accurately teams triaged simulated casualties?
Researchers also measured participants' confidence, knowledge, attitudes, views of the debrief, and views of MCIPHER. Each team managed the same simulated incident involving 25 casualties. The exercise lasted about 60 minutes and was followed by a structured debrief lasting about 20 minutes.
详细描述
This completed proof-of-concept study used a quasi-experimental, non-randomized, two-group design. All participants completed a standardized two-week didactic curriculum on mass-casualty incident response. Group A completed the first tabletop exercise without exposure to MCIPHER. Group B received an additional structured MCIPHER pre-brief immediately before the first exercise.
Each group formed one team and independently managed the same three-dimensional tabletop scenario involving 25 simulated casualties. A game master controlled scenario progression and provided neutral prompts only when a team stalled for at least 30 seconds after a cue. The active exercise lasted approximately 60 minutes and was followed by an approximately 20-minute structured debrief. Only each team's first exercise was used for the between-group comparison to avoid carryover learning effects. Group A later received access to the MCIPHER educational content, but later performance data were not included in the analysis reported in this record.

结局指标
主要结局
Percentage Team Performance Score During the First Tabletop Exercise
时间窗: During the first tabletop exercise, approximately 60 minutes
Each team's performance was assessed across 20 predefined critical actions spanning command, triage, treatment, transport, and closure. Each action was scored as 1.0 for full completion in the correct sequence and within the timing window without prompting, 0.5 for partial, delayed, incomplete, or prompted completion, and 0.0 for an action that was not observed, incorrect, or out of sequence. Scores were summed, divided by 20, and multiplied by 100. Scores range from 0 to 100 percentage points; higher scores indicate better team performance.
Percentage Operational Timeliness Index During the First Tabletop Exercise
时间窗: During the first tabletop exercise, approximately 60 minutes
The number of 20 predefined critical actions completed within their benchmark timing windows, allowing a plus or minus 2-minute tolerance, was divided by 20 and multiplied by 100. Scores range from 0 to 100 percentage points; higher scores indicate that a larger proportion of critical actions were completed on time.
Percentage Initial Triage Accuracy Score During the First Tabletop Exercise
时间窗: At completion of initial triage during the first tabletop exercise, within approximately 60 minutes
The number of 25 simulated casualties assigned the correct initial triage category compared with the predefined gold-standard category was divided by 25 and multiplied by 100. Scores range from 0 to 100 percentage points; higher scores indicate greater initial triage accuracy.
