Quick thoughts from TriCON 2012

The theme for the TriCON 2012 conference in San Diego was “Breaking Barriers” and that is certainly what TriTech presented during the plenary yesterday regarding their next generation dispatch system and their consolidation of recent business acquisitions.  The crowd was clearly the biggest ever for this conference at about 430 users.  A show of hands made it clear that the majority of these attendees were VisionAIR clients with VisiCAD users a clear runner up in representation.  However the future direction for TriTech was definitely a merger of several systems, both internal and external to the business, as explained during the opening session called “TriTech Update: One Company.”  It was explained that the products would be simplified into a family under the names of “Inform”, “Perform”, and “Respond.”  While the names were beginning to be used this week, it was admitted that it will take some time for the actual rebranding to be complete.   Attendees at this conference would almost exclusively fall under the “Inform” name reserved for the larger volume clients using applications now called VisiCAD or VisionAIR.  Smaller dispatch clients would be in the “Perform” category and “Respond” will include EMS and billing systems.

This type of re-categorization even extended into a restructuring of the organization around functional “centers of excellence” that would be geographically recognized.  San Diego, for instance, will become the center including GIS integration and Castle Hayne will host law enforcement functions.  Darrin Reilly, the new COO, explained the need to reorganize the company allowing them to take advantage of future trends given that fact that “IT evolution will be greater in the next 12-60 months than ever before.” (more…)

Measured Response to Response Measures

In conversations lately I have been hearing more diverging opinions on measuring EMS response ranging all the way from it being a definitive criteria to saying  it shouldn’t be considered at all. A recorded example of such a discussion is a recent blogtalkradio episode by “EMS Office Hours”.  While certainly appearing to be diametrically opposing opinions on the surface, I believe that there is more in common between these positions than actual difference.  Everyone agrees that responder safety is paramount and also that speeding ambulances endanger not only the medics, but the public as well.  However, to assume that the “observer effect” of simply measuring the response time is a casual factor in promoting unsafe practice is not always justified.

To clarify the commonality, it is worthwhile to first discuss the measurement itself.  When does the clock measuring response performance actually start and when does it stop?  The answer likely depends on your perspective.  As a patient in cardiac or pulmonary distress, rescuer performance is rightfully measured from symptomatic onset to relief.  For a dispatcher, it can be from the point of answering the call for service to the paramedic greeting the patient.  For the responding agency, it can be from the initial dispatch time to the time of “wheels on the curb” at the scene.

In reality, it doesn’t matter what you choose measure, the point is ultimately how efficiently can service safely be rendered to achieve a positive clinical outcome.  Opponents to time response measures will say that the focus is brought to the wrong objective.  That only (more…)

Addressing Geovalidation

The most fundamental aspect of an E-911 emergency dispatch center is to be able to locate a call for service and communicate that location to the closest appropriate vehicle to be dispatched.  In nearly every case, that location description is eventually an address.  The back-end process starts when a call is placed to 9-1-1 from a traditional wired land-line and its Automatic Number Identification (ANI) is compared to phone company records to find the Automatic Location Identification (ALI) address which is then compared to the Master Street Address Guide (MSAG) database to determine which Public Safety Answering Point (PSAP) or “call center” will receive that call.  It is the dispatcher at the PSAP who will determine the required resources and ultimately dispatch the requested assistance.  For cellular phones, VOIP, or telematics, the process is a little more complex to return a current latitude/longitude coordinate rather than a pre-determined address.  In those cases, the PSAP will interpret the caller position to a nearest address using Geographic Information System (GIS) technology.  The process of turning an address into a latitude/longitude value is called “geocoding” by GIS people and “geovalidation” by EMS staff.  The inverse of that process, finding the address of a specified point, is preceded with the term “reverse” by either crowd.  So, regardless of how the location information is presented to the PSAP, the closest resources can be found by comparing points and, in return, an understandable location descriptor can be provided for any point – at least in theory.
