The Office of Emergency Medical Services (OEMS) is installing the new Schematron file on MATRIS with updated validation rules on Tuesday November 1, 2022 at 9:00AM EST. Any runs that are imported into MATRIS after that time will be validated against this new set of rules.  The majority of the updates made existing rules less restrictive. Please work with your vendor to ensure that your ePCR is updated.

The specific updates may be found in the attached files and are posted on the NEMSIS website https://nemsis.org/state-data-managers/state-map-v3/massachusetts

This is also a reminder that the update to the Administrative Requirement 5-403 updating the required number of days to submit from 14 to 7 becomes effective tomorrow November 1, 2022  as well.
