This study is to test the use of simulation training to improve 9-1-1 telecommunicators' call processing and response. Training sessions will expose 9-1-1 telecommunicators to several realistic emergency situations through mock 9-1-1 calls with a trained actor playing the part of a reporting party, followed immediately by feedback on call handling provided by a trained call observer. Investigators hypothesize that simulation followed by trained observer-directed feedback will increase correct triage of medical emergency and delivery of pre-arrival instructions during simulated calls and in actual 9-1-1 calls.

Participants randomized to the intervention arm receive telephone simulation training.
telephone simulation training
The intervention consists of four 20-minute telephone simulation training sessions over a 4 month period (one session each month). Each 20-minute training session will include 3 simulated 9-1-1 calls, performed by a standardized caller (trained actor) and feedback will be provided right away by a trained observer who takes notes during the simulation calls and discusses the teaching points after the session. In total, the 9-1-1 dispatchers will receive 12 different simulated calls.

Primary Outcomes

Change in elapsed seconds from call answer to start of telephone-cardiopulmonary resuscitation (T-CPR) instructions in cardiac arrest calls in simulations and in actual calls.
time frame: Once monthly over 4 months (during simulations); at event (actual cardiac arrest 9-1-1 call) over 12 months.

Secondary Outcomes

Change in proportion of calls with querying behaviors compliant with the "all-callers" interviewing protocol.
time frame: Once monthly over 4 months (during simulations); at event (actual cardiac arrest 9-1-1 call) over 12 months.

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: 9-1-1 call-center call receivers. - Exclusion Criteria:
