NEMSIS

Description

The National Emergency Medical Services Information System (NEMSIS) is a US-based national EMS database recognized as the universal resource for patient-care information resulting from 911 emergency calls.

Specifically, NEMSIS provides the framework for collecting, storing, and sharing standardized EMS data from States nationwide. These EMS data have been used for epidemiology and research studies as well as by local, state, and national EMS stakeholders to more accurately assess EMS needs and performance, as well as support better strategic planning for the EMS systems. In addition, data from NEMSIS is also used to help benchmark performance, determine the effectiveness of clinical interventions, and facilitate cost-benefit analyses.

Of important note is that the EMS data available in NEMSIS database is transport and not individual level data, which means that multiple transports may relate to a single person. The linkage between transports and patients is not available in the public data release.
