The Present where we are nowThe Future where we are goingEMS in GeorgiaDiscussion
Out of Hospital Cardiac Arrest (OHCA)Is the sudden, unexpected natural death from a cardiac cause a short time (generally < 1 hour) after the onset of symptoms (if present) in a person without any previous condition that would seem fatal.
Gillum and colleagues have defined SCD as any cardiac death occurring outside the hospital or taking place in the emergency department.

Benefits of Data Collection
Uniform collection and tracking of data facilitates better continuous quality improvement within communities.Enables comparisons across the systems for clinical benchmarking to identify opportunities for improvement.

NEMSISFuture language to be spoken
Many Lives are Lost Across USABecause Emergency Services Fail. (USA TODAY, 2003, Robert Davis).
Surveyed the Countrys 50 largest cities.
38 of the 50 either could not, or would not, report their communities cardiac arrest survival.
Article series revealed the major reasons why EMS in most cities save few people.
USA TODAY, 2003, Robert Davis
Most cities dont measure their performance effectively, if at all. They dont know how many lives they are losing, so they cant determine ways to increase survival rates.
Need for RegistryData collection into a registry at the regional, state or national level enables EMS systems to collect data in a standardized NEMSIS compliant fashion. Strengths and weaknesses in a community can be identified when comparison with the benchmarked dataset is made. Future performance measures need to based on compliance with evidence based guidelines.
IOM Report on Emergency ServicesWhat is missing is a standard set of measures that can be used to assess the performance of the full emergency and trauma care system within each community, as well as the ability to benchmark that performance against statewide and national performance metrics.
IOM Report on Emergency ServicesWhile a full-blown data collection and performance measurement and reporting system is the desired ultimate outcome, the committee believes a handful of key indicators of regional system performance should be collected and promulgated as soon as possible. Cardiac arrest, pediatric respiratory arrest, blunt trauma with shock.
CARES Program OverviewIdentify and collect pre-hospital cardiac arrest events to improve survival outcomes.
Establish a method for uniform consolidation of EMS, 911, and hospital information.
Generate reports of response intervals and patient outcomes for involved agencies in useful format.
Allow participating agencies to confidentially benchmark performance.
The THREE SILOS OF DATAImportance of Data Elements and Linkage to CARES
CARES NETWORK
CARES Program DatabaseSansioMainframe housed in Duluth, MNInternet database systemhttps://mycares.netHIPAA compliant securityUnifies EMS, 911, and Hospital dataAny EMS system throughout US
EMS ComponentCollection methodsDirect entry onlineIntegration of CARES data fields onto EMS tablet/laptop softwareScanned CARES formQuery to ensure capture of dataManual or through PCR documentation systemsEMS initiates event and signals other two componentsGenerates email to Hospital componentMatches event with daily 911 import
911 CAD ComponentCall number on CARES form identifies Computer-Aided Dispatch (CAD) record.Times are forwarded to database daily using auto-extraction tool.Unmatched CAD times are identified and matched manually.Likely matches ranked based on Date, Time, and Address.Matches confirmed by EMS agency liaison
Hospital ComponentHospital follow-up only required on patients where outcome is ongoing resuscitationHospital contacts set up through CARES administrator.EMS CARES data triggers an email to primary hospital contact requesting hospital outcome.When all three data components form a complete record of the event, the data is de-identified of unique patient identifiers (name and DOB).

CARESUltimate goal of CARES will be to help local EMS administrators and medical directors identify: Who is affected.When and where cardiac arrests occurWhich elements of the system are functioning well and those that are not.How changes can be made to improve cardiac arrest outcomes.
Obstacles in Data CollectionOwnership of Data need for data use agreement.
Data Security need for HIPAA compliance, internet firewall, and encryption of data.
Confidentiality need for data use agreement.
Fragmented System lack of linkage with 3 silos of data; need to automate data collection process to bring together 3 separate datasets
CARESCreated a model cardiac arrest registry capable of identifying and tracking all cases in a defined geographic area.Year One -- Fulton County, Georgia.Year Two -- Multi-County Area of metropolitan Atlanta, Georgia.Year Three Began National Expansion.Ultimate goal is to be universally applicable to EMS operations nationwide.

For every minute that defibrillation is delayed, the chances of surviving sudden cardiac arrest (SCA) are reduced by approximately 10%. Survival chances drop particularly fast in the first five minutes.Since rapid time to defibrillation is so critical, expanding the number of early defibrillator responders offers SCA patients a real chance to survive an otherwise lethal event.In fact, by extending defibrillation skill using AEDs to more responders, survival rates have increased dramatically in some settings; e.g.:40% survival-to-hospital-discharge (neurologically intact) in Rochester, MN with police first responders (White RD. Resuscitation 1998).70% survival-to-hospital-discharge in Nevada casinos (Valenzuela TD Acad Emerg Med 1998).80% survival-to-discharge in the Chicago Airport System, compared to a 3.5% save rate in Chicago with a paramedic response (USA Today, December 28, 1999).
This is just a snapshot of the hospital data entry screen. You can see the four hospital questions. There is also a transfer feature where if a pt was transported by EMS to hospital #1 then the pt was transferred from Hospital #1 to Hospital #2 there is a way to indicate this by selecting the transfer hospital in the drop-down menu. The hospital contact at #2 gets an email and the pt is now in there box for pending hospital outcomes.
