History

Utah has a long and successful history of prehospital data collection. POLARIS will extend that success into the future. Here's a quick look at the history of prehospital data in Utah:

POLARIS is needed for the following reasons:

• AIS is outdated: AIS put Utah at the forefront of data collection for many years. However, AIS is now ready to be replaced. The DOS-based program has become difficult to install and use on newer computers. AIS offers no interface for integrating with other systems, such as commercial data collection systems and computer-aided dispatch systems. AIS also provides limited reporting and analysis capabilities for today's EMS environment.
• NEMSIS has been adopted nationally: Utah has committed to develop a NEMSIS-compliant prehospital data system and to begin providing data to the national NEMSIS data repository by the end of 2007. POLARIS will serve as our NEMSIS-compliant state data repository and also provide a data collection interface that will be available free of charge to all EMS agencies in the state.

Data Lifecycle

POLARIS is a key component of Utah's overall EMS system, as illustrated in the following diagram:

Data lifecycle of prehospital patient care

Many people participate in the system:

• EMTs and paramedics submit run reports (PCRs), and can also view any reports they’ve submitted and perform analysis on them.
• Computer-aided Dispatch (CAD) systems can provide dispatch data that will create a “stub” of a PCR for EMS personnel to complete, requiring less data entry and providing more accuracy (this is a future capability).
• Agency administrators submit information about their agency (“demographics”) to POLARIS. They also use POLARIS to do analysis for quality assurance and quality improvement.
• Hospital personnel have access to PCRs for patients delivered to their hospital as soon as the EMS personnel start a PCR and designate the hospital as the destination.
• The Utah Bureau of EMS houses data as the regulatory agency designated by statute. The burau uses data for analysis and statewide reporting.
• The State Epidemiologist is notified when possible bioterrorism events are detected, and a public health investigation is initiated.
• A subset of POLARIS data is sent to the National NEMSIS Database (future capability), which will make summary data available to researchers and federal and state governments for analysis and system improvement.

Features and Benefits

POLARIS will bring several benefits to the EMS system at the local, state, and national levels:

• Accuracy: POLARIS validates each data element entered on a PCR, and it also checks over 60 cross-element validation rules. This higher level of error checking allows personnel to correct accidental data entry mistakes immediately, resulting in more accurate records.
• Patient care: Effective patient care is improved when each caregiver has access to relevant information. POLARIS will link PCRs from different units responding to the same patient on the same incident, and it will also make prehospital care information immediately available to hospitals, prehospital agency administrators, billing agencies, and the bureau.
• Improved Payment Recovery: "The first invoices and insurance claims should be mailed within 72 hours form the time of service. Quick information processing, prompt insurance claims filing, and invoice mailing have the greatest positive impact on collection rates." (Fitch, J, 2004, Prehospital Care Administration, p. 386). By enabling real-time electronic data collection and by providing real-time biller access to patient care reports, POLARIS can help agencies to greatly improve the speed with which they prepare billing statements.
• Data import/export: Data can be imported into POLARIS and exported from POLARIS in NEMSIS format.
• Third-party software integration: Agencies can purchase NEMSIS-compliant software from vendors and use POLARIS's back-end web service to upload and download data behind the scenes.
• Incident and patient linkage: When two crews initiate PCRs for the care of the same patient on the same incident, the data entered by the first crew is used to reduce the data entry required from the second crew. When the second crew starts their PCR, all of the data that would be common to the two PCRs (such as incident location and patient information) is pre-filled based on what the first unit entered.
• Bio-terrorism surveillance: The Bureau has identified 13 bio-terrorism indicators. If a particular indicator is flagged on an unusually high number of calls within a certain geographic area during a period of time, POLARIS triggers a notification to the state epidemiologist so that a public health investigation can be initiated. With effective bio-terrorism surveillance, the bureau can instantly mobilize statewide resources to respond to critical incidents.
• Staging locations: By reviewing response times through POLARIS, agency administrators can identify geographical areas that need better coverage and then move unit staging locations to eliminate gaps in service.
• Real-time analysis: The day after a PCR is completed, it will become available for analysis at the agency, hospital, and state levels. Analysis will no longer need to wait until the end of the year.
• Training improvement: Agencies can use POLARIS's analysis tool to identify training needs specific to their agencies. Nationally, NHTSA can use nationwide NEMSIS data to implement changes in the national standard curricula.
• Justifying EMS: EMS is "the last bastion of healthcare to prove that what it does makes a difference." The rest of the healthcare industry justifies its value by using data that shows that it makes a difference in patient outcomes. EMS is now being asked to show its value, and data analysis is one way to do so.

System Architecture

POLARIS is designed to be highly reliable, available, and secure. POLARIS is hosted in state-owned computer facilities, and the POLARIS servers are not shared by any other systems.

The production data center houses multiple load-balanced servers. If one server goes offline, POLARIS will continue to function. If all production servers go offline, a backup server will handle POLARIS traffic from a remote data center location. POLARIS also has a development server, used to test system enhancements before they are published to the production system.

Regardless of the status of the individual POLARIS servers, POLARIS will always be available at polaris.utah.gov.
