The Evolution of EMS Data

Michael SchnyderNEMSIS Technical Assistance Center

Overview• The purpose of this presentation is to

provide you with an opportunity to learn more about EMS data systems and ask me questions– Pre-NEMSIS– NEMSIS– Pilot Project– Where we stand today– What’s next for EMS Data

History of EMS Data• We can date it back to the “modern age of

EMS” – 1966: Accidental Death and Disability

“A review of ambulance services in the United States indicates a paucity of information and a limited framework for the collection of data on and the evaluation of current ambulance services.” (Page 13)

So What Happened Between Then and Now?

• Largest event happened in 1992-1993– The NHTSA EMS Data Elements Version 1

• Great try, the spirit was there• Too loose of a standard• EMS relatively uneducated to the potential of

computer technology

• States went on their own

• The NEMSIS Project

KEY:

Active Data System

Working on a System

No System / Unknown Source: NEMSIS TAC

The NEMSIS Project• Late 90’s, the National Association of State EMS

Directors decided there was a NEED for uniform data collection

• EMS Education– Curriculums– Local Education

• EMS Outcomes– Something other than death– System evaluation

The Need• EMS Research

– Generate hypothesis– Evaluate cost-effectiveness– Identify problems and target issues

• EMS Reimbursement– National fee schedule and reimbursement rates

The Original Team• NASEMSD

– Project Management, Regional Meetings Operational Support

• Greg Mears, MD (Principal Investigator)

• NEDARC– Clay Mann, PhD, Co-Investigator– Mike Dean, MD, Co-Investigator– Technical Assistance

• State Data-Managers

The Money• NHTSA

– EMS Division (Primary)

• HRSA– EMS-C, Trauma, and EMS

• American Heart Association– Support for EMS Software Development

The ConsensusProfessional Organizations

• AAA• AAMS• ACEP• ACS-COT (NTDB)• AHA (NRCPR)• EMSOP• IAFC• IAFF• NAEMD• NAEMSP• NAEMT• NASEMSD• NENA

Federal Partners

• CDC• FEMA• HRSA-EMSC• HRSA-EMSC/NEDARC• HRSA-EMSC/NRC• HRSA-ORHP• HRSA-Trauma/EMS• NHTSA

This Desire…• Turned into the revision of the National

EMS Dataset

• More than just a dictionary– Why each element exists– The use and purpose of each element– How to store and send the data– How they interact with each other

NEMSIS Overview• Composed of two components:

– Demographic dataset: • Standardized set of data fields that

describe an EMS system

– EMS dataset:• Standardized set of definitions describing

an EMS event

NEMSIS Overview• Both have the following:

– XML (eXtensible Markup Language ) formats – XSD (XML Schema Definition)

• Provides the capability of moving data from one system to another

• XML provides the method on which data is stored

• XSD provides the definition and rules for a field

NEMSIS Overview• Date of Birth

– You don’t want to have people enter any data into the field.

• You need them to:– Complete the field– Format: MM/DD/YYYY– Range: Today’s date to 125 years ago

• Portability means:– Ease of movement of the data

– Commonality of the elements to be moved

– Software vendors developing applications that can be used across the country

Portability!

Questions So Far?

NEMSIS TAC• The TAC picked up the work at the end of

the Pilot phase of NEMSIS (Sept 2005)– University of Utah received the grant– Utah contracted with University of North

Carolina to continue their efforts

• The Goal is to collect data from States and Territories to create the National EMS Database

NEMSIS TAC• Simple goal, complicated objectives

• This means that the TAC will be offering assistance to:– States– Local EMS agencies– Software developers

NEMSIS TAC Resources• www.nemsis.org • Reference Documents• Communication and Public Education• Maintain Dataset and XSD• Development Tools• Direct Technical Assistance• National Database Development• Other

www.NEMSIS.org

Software Compliancy• On March 1, 2006, the TAC began testing

software developers for compliance

• There are two levels of compliance:– Gold– Silver

Silver and Gold Compliance

Silver

• Must have the National elements

• Any additional elements must comply with the standard

• Must create the right XML/XSD files

Gold

• Must be able to offer all of the elements found in the NHTSA dataset

• Must create the right XML/XSD files

Compliance• Upon successful completion of the

compliance certification, the developer and application will be posted on the NEMSIS site

• Always remember to be an informed customer (There is the possibility of cheating the certification process)

Compliance So Far• With held three testing sessions in 2006

– 24 software applications were tested– 18 successfully passed the process– 9 Gold-level and 9 Silver-level products

• Three testing sessions for 2007– Current session just began and results will be

made available at the end of February

Some Items about Data Systems

• HIPAA and other legal issues

• Performance Improvement

• National EMS Database

HIPAA & Legal Issues

• Fact: HIPAA issues exist and local EMS agencies must adhere to this law

• Fact: Most states are following HIPAA-like principles within their own domain– But states are exempt from this law

HIPAA & Legal Issues

• States sponsoring data systems – Still have agencies follow HIPAA– Help agencies do so

• State collecting data– Still will collect PHI (data linkage)– Local agencies are in compliance

Legal Issues• States still need to look at two issues

– One: Having the mandate to collect data• Most have existing laws but they are older than

computerized technology• These laws need to be updated

– Two: Having data protections in place• QI protection• Open Govt. protection

• How are we doing as a system?

• What we should be doing as a system?

So What Do You Want to Be Able to Do with the

EMS Data System?

National EMS Database

• Data from 3 states– NEMSIS-based data– MN, NH, NC– EMS events from 7 states– 500,000+ records (changes weekly)

NED: It Exists

• Database and Reporting– Housed in Utah

– The first reports will be “canned”• Target to have them by March 1, 2007

– NEMSIS TAC hiring a reporting specialist• To refine the data coming into the system• To create an automated system (Fall ’07)

NED: It Exists

Conclusion• The NEMSIS Standard is here to stay

• Colorado is making a good start at getting a system in place– I predict they would love to get input from you about

the development and implementation of the system

• Remember:– “Every positive action requires expenditure”

-President Dwight D. Eisenhower
