The primary purpose of EMS data collection is for the improvement and support of EMS systems, research, and delivery of quality patient care. The collection of reliable, comprehensive, valid data from Massachusetts ambulance services allows the Department of Public Health (DPH), ambulance services, and EMS Medical Directors to work collectively to assess the quality of care delivered to patients with the fundamental objective of quality improvement.
