What Every EMS Agency Should Know About NEMSIS? – It’s clear that improved data collection would help EMS agencies better target their efforts and provide life-saving information to those in need. To provide the best possible care, Emergency Medical Services (EMS) agencies must stay up-to-date on the latest tools and resources to provide the best possible care.

One such resource is the National Medical Services Information System (NEMSIS), a database that collects and stores data on medical encounters across the United States. However, it is essential to note that NEMSIS is only as good as the data entered. To get the most out of NEMSIS, EMS agencies must ensure that their data is complete and accurate.

This blog will explore what NEMSIS is, how it is used, and why EMS agencies need to be familiar with it.

What is NEMSIS?

NEMSIS is a national database that collects and stores data on EMS encounters in the United States. This data includes patient demographics, the nature of the medical complaint, the type of care provided, and the patient’s outcome. The database was created in response to a need for more comprehensive and accurate data on EMS encounters, as previous data collection methods were often inconsistent and incomplete.

How is NEMSIS Used?

NEMSIS collects data on EMS encounters to improve patient care, monitor the quality of care provided by EMS agencies, and track trends in patient outcomes. The data collected by NEMSIS can be used to identify patterns and trends in patient care, which can inform research and policy decisions related to EMS.

For example, NEMSIS data can identify areas where EMS agencies may need to improve their care by identifying common medical complaints or conditions requiring additional training or resources.

Additionally, NEMSIS data can be used to track the effectiveness of specific interventions or treatments and to identify best practices that can be shared with other EMS agencies.

Why Is NEMSIS Important For Ems Agencies?

It allows EMS agencies to track the care they provide and identify areas for improvement. By regularly reviewing NEMSIS data, EMS agencies can identify patterns and trends in patient care and take steps to address any issues that may be identified.

NEMSIS data can be used to inform policy decisions. In addition to improving patient care, the data collected by NEMSIS can be used to inform policy decisions at the local, state, and national levels. This helps ensure that EMS services meet the community’s needs and effectively address public health concerns.

Also, the data collected by NEMSIS is used for research and analysis. This can help to identify trends and patterns in EMS data and inform the development of best practices and policies.


In the end, NEMSIS provides tools to help agencies better manage their data and serve their communities more effectively. Regardless of the state you work in, there is information that can mitigate risk when responding to emergency calls. It can even provide valuable information to your healthcare team at the hospital. And that’s always a welcome development. The more agencies that participate, the greater the data that can be collected to understand better what threat levels might be in place for different call types.
