Quality Management
Data Analysis and Information Management (DAIM) provides continuous quality improvement initiatives, commitment to a customer-based way of doing business, and enhances the ability to effect improvement in related fields.

EMS Surveillance Measures
MIEMSS maintains several EMS system surveillance priorities based on routine data review, customer requests, and research outcomes. Throughout FY 2025, hospital yellow alert demand was monitored at state, regional, jurisdictional, and hospital-specific levels through the online County Hospital Alert Tracking System (CHATS) for real-time system response capabilities as well as historical trends. The Emergency Department Advisory System (EDAS) will replace the CHATS legacy system in August 2025. This monitoring, coupled with hospital strategies that address the high demand for emergency department services, helps improve the availability of this vital service system wide. Yellow alert data also form one measurement in the Maryland Department of Health’s (MDH) syndromic surveillance programs.

The Helicopter Utilization Database (HUD) accounts for all helicopter requests for transport independent of actual transport mode outcome, and permits requesting EMS managers and medical directors to conduct case reviews. HUD data analysis supports MIEMSS’ efforts to utilize aerial transportation for only the most severe, time-critical incident scene patients statewide.

Since FY 2017, EMS interventions involving naloxone administration for opioid overdose cases have been consistently recorded and relayed to both MDH and Maryland’s Office of Overdose Response. This non-confidential data, in conjunction with other valuable resources, serves as a crucial tool in tracking opioid overdose trends and devising effective strategies to address this unrelenting crisis.

Data Confidentiality 
MIEMSS maintains or has access to eight confidential databases used to ensure the delivery of quality EMS care. The Data Access Committee was formed to ensure that all data and requests for information are expedited efficiently and accurately while ensuring patient and clinician confidentiality at all times. Since January 2000, MIEMSS has tracked and responded to over 3,500 data requests.

Maryland Emergency Medical Resource and Alerting Database (MEMRAD)-NG
The Maryland Emergency Medical Resource Alerting Database (MEMRAD) serves as Maryland’s statewide health and medical alert and resource tracking system. Administered by MIEMSS, this system connects hospitals, EMS, Public Health, Emergency 65 RESEARCH AND EVALUATION Management and other local, state and federal partners for realtime information sharing. During FY 2025, MIEMSS deployed the Next Generation (NG) upgrade of the legacy MEMRAD system bringing about an advanced alerting and notification system, and resource tracking and information sharing system. The new MEMRAD-NG integrates seamlessly into the Emergency Department Advisory System (EDAS), and has additional functionality which will be rolled out over the next year.

@Hospital Ambulances (@HA)
System Evolution The At Hospital Ambulances (@HA) app continued to serve as a web-based application displaying ambulance activity at each of the Maryland hospitals utilized by jurisdictional EMS clinicians during FY 2025. The Data Analysis and Information Management (DAIM) department had developed this application to work on desktop computers and mobile devices, including iOS, Android, and Windows mobile devices. The @HA application displays information about ambulances located at the hospitals, including the hospital name, number of ambulance units, alert status, and length of stay based on data received from the EMSOP’s Computer Aided Dispatch (CAD) Systems.

Emergency Department Advisory System (EDAS)
Development As part of the broader emergency department monitoring system modernization initiative, MIEMSS continued developing, incorporating, and expanding the original @HA functionalities that is evolving into the comprehensive Emergency Department Advisory System (EDAS).

EDAS development, completed in July 2025 for implementation in August of 2025, represents a comprehensive, web-based solution designed to use inputs from computer-aided dispatch systems via ImageTrend™ and the Maryland Emergency Medical Resource Alert Database (MEMRAD) to provide an objective overview of the state’s EMS system with a focus on emergency department capacities. Unlike CHATS, which provided subjective assessments of emergency department “busyness,” EDAS will convey objective assessments based on emergency departments’ patient census relative to pre-determined capacities vetted with emergency department leaders at each facility.

MIEMSS collaborated extensively with emergency department leaders and EMS stakeholders to develop and refine EDAS capabilities. The system incorporates enhanced ambulance tracking functionality, displaying both ambulances currently located at hospitals and those en route to each facility. Additionally, EDAS includes filtering capabilities that allow system users to focus on emergency departments of routine interest, providing EMS clinicians with improved decision-making tools for patient destination choices.

Online Training Center: 
Last year, MIEMSS significantly enhanced its Online Training Center (OTC), emphasizing improved usability and a modern design. This advancement aligns with our agency’s mission to offer unparalleled continuing education opportunities to the State’s EMS clinicians. Built on the robust foundation of Moodle – a renowned, open-source Learning Management System – the OTC seamlessly integrates with the MIEMSS Licensure System. We eagerly anticipate rolling out additional updates in the forthcoming months.

Chesapeake Regional Information System for our Patients (CRISP) and eMEDS® Integration Project
The integration of eMEDS® with Chesapeake Regional Information System for our Patients (CRISP), the health information exchange service for Maryland and Washington, DC, is an important ongoing project. Data Analysis and Information Management (DAIM) has enhanced this integration to allow CRISP to receive additional patient care data on a more frequent basis. Currently, EMS reports are securely transferred to CRISP in close to real time. This integration makes the EMS report available to all health care clinicians with CRISP access, including those in primary care. Aligning these two systems makes prehospital emergency care information available to participating physicians and hospitals throughout the state. A future phase of the project aims to make select patient medical data, such as medical history and medications, available to EMS clinicians to enhance the care they are able to provide at the patient’s side.

Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE) and eMEDS® Integration Project
MIEMSS’ Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE) interface links EMS patient encounter data with other statewide healthcare data shared with ESSENCE. This combination of EMS, Hospital, Primary Care, Pharmacy, and other data sources gives public health partners enhanced situational awareness for potential disease outbreaks and epidemics.

Maryland Traffic Records Assessment
In the fall of 2024, Maryland volunteered for a National Highway Traffic Safety Administration (NHTSA) peer review assessment of our management and use of motor vehicle crash-related data. Two EMS-related programs contribute essential data to our state’s injury surveillance system as defined by NHTSA. This includes all traffic-related etiology records entered in eMEDS® or the Maryland Trauma Registry. Of the 46 assessment questions pertaining to MIEMSS programs, 43 received a “Meets Advisory Ideal” rating, one received a “Partial” rating, and two received a “Does Not Meet” rating. These findings are exceptional when compared to other state assessments. One of the key findings found under assessment “Strengths” was that Maryland continues to support and improve all the components of a comprehensive statewide injury surveillance system, and Maryland has a long history of integrating multiple transportation safetyrelated datasets.

Trauma Registry
The Maryland Trauma System focuses on a multidisciplinary approach to care for injured patients. The Maryland Trauma Registry (MTR) supports that initiative. All Maryland designated trauma centers abstract and enter data into the MTR. This data entry allows for a streamlined process of patient identification and injury definition. The MTR provides foundational support for the continuum of high-quality care across Maryland by producing standardized and consistent data to be used for the following purposes: • public health surveillance • data analysis • research assistance • performance improvement • injury prevention • education and best practice dissemination • outcome assessment • trauma center system development Additionally, the trauma centers submit their data to the National Trauma Data System for trauma benchmarking across the United States.
