Information Gaps 1. Response Times: • What are our average delays … time lapse between dispatch and en route?
• How do these delays vary on nights, weekends, etc.? 2. Second Unit Response: • What percentage of calls require a second unit response?
• What percentage of calls require multiple units? 3. Incident Locations: • What are the actual locations (addresses) of EMS incidents in coverage area?
• What are the time/day of week characteristics of our calls?
• What is the distribution of our EMS incident types (ALS vs BLS calls)?
