Top Ten Dispatch Problems
These are the most common problems identified at time of dispatch for the 2017-18 fiscal year.
The first word or two describes the problem: Traffic Injury, Fall, etc.  Pri means “Priority.”  The following number indicates the urgency of the incident on a scale of 1 (highest) to 5 (lowest).  “F” tells the dispatcher to make sure first responders have also been sent, since Priority 4 incidents usually get only an ambulance.


Figures are for the 2017-18 fiscal year.
  • 911 incident count: 123,420
  • 911 ambulance responses: 139,431
Response Time Performance
Response intervals begin when a Communications Medic answers a 911 call, and end when the first ATCEMS unit arrives on scene. We do not include incidents referred to us by another agency in this measure. We also exclude pre-planned events such as the Austin City Limits Music Festival or Formula One, as well as incidents occurring outside our primary service area (mutual aid incidents).
This indicator measures percentage of incidents for which ATCEMS meets its response interval goals. Our target is to meet these goals (shown in minutes and seconds) for at least 90 percent of all incidents:
City of Austin Response Interval Goals
Priority 1 -- 09:59
Priority 2 -- 11:59
Priority 3 -- 13:59
Priority 4 -- 15:59
Priority 5 -- 17:59
Travis County Response Interval Goals
Priority 1 -- 11:59
Priority 2 -- 13:59
Priority 3 -- 15:59
Priority 4 -- 17:59
Priority 5 -- 19:59
We measure performance at multiple levels. We look at the system as a whole, and at each service area -- City and County. We also measure compliance at each priority level in the City of Austin and in Travis County.
The following chart shows response interval compliance performance for ATCEMS for FY2017-18.

Patient Management

Figures are for the 2017-18 fiscal year.
  • Patient contacts: 101,698
  • Patient transports: 79,924

Top 10 Primary Impressions
The primary impression is the main problem treated by our crews, as documented on the patient care record (PCR).  Crews select an impression from a list available in the PCR system.  “Unspecified condition” is generally used if the crews cannot identify an impression that is appropriate to a patient’s situation.
This chart shows the 10 primary impressions documented most often by our crews for FY2017-18.
Transport Destinations
This map shows the count of patients transported to each facility and percent of all patients transported for FY2017-18.
We transport to acute care hospitals and to free standing emergency departments.  All receiving facilities are approved by the Austin-Travis County EMS System Office of the Medical Director (OMD).  A number of hospitals have specialty capabilities, including:
  • Trauma centers
  • Pediatric centers
  • Primary and comprehensive stroke care
  • Heart attack care ("STEMI" centers)
Use this map to see the count of patients that a facility received via ATCEMS transport in fiscal year 2017-18. The pop-up also shows the percentage of all system transports for the year received by the facility, and the specialty capabilities of the hospital, if applicable.
  • Dell Seton Medical Center at the University of Texas opened in May 2017.  It takes the place of University Medical Center at Brackenridge in the Austin-Travis County EMS System; that hospital closed shortly after Dell Seton Medical Center opened.
  • A "Comprehensive Stroke Center" can receive all patients displaying stroke symptoms, regardless of when the event started.  "Primary Stroke Centers" can receive patients whose symptoms are less than three hours old, AND if transport time to the closest Comprehensive Stroke Center is more than 15 minutes longer than transport time to that hospital.
