Table 1 Outcome Measure and Data Collection Tools

From: Protocol: simulation training to improve 9-1-1 dispatcher identification of cardiac arrest

Aim Outcome measure Data collection tool
Primary aims   
Test if phone-based standardized patient simulation training:
1. Improves 9-1-1 dispatchers’ ability to identify the need for T-CPR during simulation calls. Proportion of calls where dispatchers recognize the need for T-CPR, as indicated by the dispatcher starting T-CPR instructions in the simulation test. Simulation test; call event codes
2. Reduces the time from call start to initiation of T-CPR during simulation calls. The elapsed time (in seconds) from the start of the call to the start of T-CPR instructions in the simulation test. Simulation test; call event times
Secondary aims   
Test if participation in the simulation training:
1. Improves 9-1-1 dispatchers’ ability to identify the need for T-CPR during actual cardiac arrest calls. Recognition of the need for T-CPR, as evidenced by the dispatcher starting instructions in actual 9-1-1 cardiac arrest calls. Recordings of actual 9-1-1 cardiac arrest calls during the study period; call event codes
2. Reduces the time from call start to initiation of T-CPR during actual cardiac arrest calls. The elapsed time (in seconds) from call start to initiation of T-CPR instructions in actual 9-1-1 cardiac arrest calls. Recordings of actual 9-1-1 cardiac arrest calls during the study period; call event times
3. Increases specific cardiac arrest identification querying skills during simulation calls Performance score on the eight trained skills in the simulation test. Simulation test; trained skills assessment
4. Improves dispatcher’s self-confidence to handle cardiac arrest calls. Self-reported confidence to handle cardiac arrest calls on a five point scale before and after the intervention. Baseline survey & follow-up Survey
5. Estimate the cost of the simulation training as implemented and projected costs when implemented by call centers. Calculated costs associated with intervention development and implementation; projected costs for field implementation. Records for expenses: Study design; staffing time (instructor and standardized patients); dispatcher time
