OKEMSIS v3.4 Migration

The Commissioner of Health has amended the current OKEMSIS Data Dictionary to align it with the Federal NHTSA standards as detailed in NEMSIS 3.4. This change will require all agencies to update their current reporting software by December 31, 2021. This migration is a minor upgrade, most of the changes are in the background and not noticeable to the medics entering data. Agencies that use a third-party vendor to enter data into OKEMSIS should contact their vendor representative about the migration.

The links below include information related to the OKEMSIS v3.4. Data from the Elite v3.3.4 database will remain accessible in the Report Writer module. If you have any questions about the OKEMSIS v3.4 Data Dictionary or Elite database please send them to or call Emergency Systems at (405) 426-8480.


Since 2002, OAC 310:641-3-160 has required all Oklahoma EMS agencies to submit data about all ambulance responses to the Oklahoma EMS Database, OKEMSIS.  The need for better national EMS data has led to the establishment of the National EMS information system (NEMSIS).  The majority of states participate in this effort.  The pre-2009 Oklahoma EMS Database was developed before NEMSIS and used an older data collection and storage format. In order to submit data as required, Oklahoma changed to a NEMSIS-compliant database (v2.2.1) in 2009 purchased with grant funding through the Oklahoma Highway Safety Office.  

Providers submit data to the website one run at a time, or in "batches".  Batch submitters need to work with their data vendors to ensure they have a compatible download format.  Most vendors have already developed NEMSIS-compliant download formats, and will need to add only the Oklahoma-specific data fields to be fully compliant.  Formats can be tested on the OKEMSIS ELITE testing, website e-mail for more information regarding the testing site).

Few things are as important to the future of EMS as good data. We need to be able to show that our work makes a demonstrable difference in patient outcomes. Thanks in advance for your cooperation as we complete this important step in the development of EMS as a profession.
