Massachusetts Ambulance Trip Record Information System (MATRIS)

Licensed Massachusetts ambulance services use MATRIS to report EMS data to the Office of Emergency Medical Services (OEMS).

The primary purpose of EMS data collection is for the improvement and support of EMS systems, research, and delivery of quality patient care. Only through collecting reliable, comprehensive, valid data from Massachusetts ambulance services can the Department, ambulance services, and EMS Medical Directors work collectively to assess the quality of care being delivered to our patients with the fundamental objective of quality improvement.
