EMSC Resource Databases



This page lists secondary data sets that contain variables related to EMSC. It is intended to serve as a resource to EMSC stakeholders and the EMSC community as they consider research in the field of EMSC.

Sponsored by the Agency for Healthcare Research and Quality (AHRQ), the Healthcare Cost and Utilization Project (HCUP)is a collection of health care databases and related software tools developed through a Federal-State-Industry partnership, to build a multi-State health data system for health care research and decision making. HCUP databases contain a core set of clinical and nonclinical information found in a typical discharge abstract including all-listed diagnoses and procedures, discharge status, patient demographics, and charges for all patients, regardless of payer. The information is translated into a uniform format to facilitate both multi-State and national-State comparisons and analyses.

The National Emergency Medical Services Information System (NEMSIS) is a national repository that will be used to potentially store EMS data from every state in the nation. Since the 1970s, the need for EMS information systems and databases has been well established, and many statewide data systems have been created. However, these EMS systems vary in their ability to collect patient and systems data and allow analysis at a local, state, and national level. 

The Centers for Disease Control and Prevention's (CDC) National Ambulatory Medical Care Survey (NAMCS) is a national survey designed to meet the need for objective, reliable information about the provision and use of ambulatory medical care services in the United States. Findings are based on a sample of visits to non-federal employed office-based physicians who are primarily engaged in direct patient care.

CDC's National Hospital Ambulatory Medical Care Survey (NHAMCS) is designed to collect data on the utilization and provision of ambulatory care services in hospital emergency and outpatient departments and in ambulatory surgery centers. Findings are based on a national sample of visits to the emergency departments and outpatient departments of noninstitutional general and short-stay hospitals. 

The CDC's  WISQARS™(Web-based Injury Statistics Query and Reporting System) is an interactive, online database that provides fatal and nonfatal injury, violent death, and cost of injury data from a variety of trusted sources. Researchers, the media, public health professionals, and the public can use WISQARS™ data to learn more about the public health and economic burden associated with unintentional and violence-related injury in the United States. 

The National Trauma Data Bank® (NTDB) is the largest aggregation of trauma registry data ever assembled. The goal of the NTDB is to inform the medical community, the public, and decision makers about a wide variety of issues that characterize the current state of care for injured persons.

The National Center for Health Statistics (NCHS)supports biomedical and health services research by providing researchers with access to important health statistics information and data from its surveys, indexes, and record linkage program. NCHS disseminates public-use data files through interactive tables, online querying tools, and direct download through its FTP file server.  

The Consumer Product Safety Commission's (CPSC) National Electronic Injury Surveillance System (NEISS) is a national probability sample of hospitals in the U.S. and its territories. Patient information is collected from each NEISS hospital for every emergency visit involving an injury associated with consumer products.
