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 |
