Center Injury Data Library
The UI IPRC houses or has expertise using the following databases:
The Bureau of Vital Statistics at the Iowa Department of Public Health (IDPH) collects and compiles Iowa residents’ and nonresidents’ death certificates (where the death occurred in Iowa), which are completed by funeral directors, medical certifiers (DO, MD, PA, ARNP), and medical examiners. The certificates are used for administrative and public health purposes, as well as by the family to resolve estate issues and obtain insurance benefits.
The Iowa Hospital Association inpatient database contains information on all acute discharges from Iowa hospitals and health systems. The outpatient database includes information on discharges from Iowa hospitals and health systems for the following: emergency room, outpatient surgery, observation outpatients, therapy, laboratory/radiology, and other outpatients.
The ITR provides comprehensive information on all trauma patients in the state of Iowa, including demographic data, pre-hospital data, intermediate facility data, receiving facility data (final hospital, if transfer), diagnosis data, and outcome data. All hospitals that provide acute care in Iowa are certified as a Level I, II, III, or IV Trauma Care Facility. All Level I, II, and III hospitals are required to submit information on trauma cases to the Iowa Trauma Registry, and data from Level IV hospitals is included if the patient dies in the hospital or is transferred to a higher-level facility. Inclusion into the trauma registry requires that trauma patients seen in a Level I – IV trauma care facility meet one of the following requirements: admission to a Level I, II, or III hospital, transfer to a Level I, II, or III hospital, or a patient that died on arrival or died during evaluation or treatment at hospital. Thus, the ITR includes all of Iowa’s trauma patients that were severe enough to require admission or transfer.
The DOT Motor Vehicle Division, Office of Driver Services collects and maintains data on all motor vehicle-related crashes in Iowa. An accident occurring anywhere within the state of Iowa causing death, personal injury, or total property damage of $1,500.00 or more must be reported on an Iowa Accident Report form. The data includes information comprised of three levels (crash, driver/vehicle, and person).
EMS programs are required to submit specified data to an EMS statewide registry, which is compatible with the current National Emergency Medical Services Information System (NEMSIS) standards. The registry, which includes over 400 data elements, consists of two datasets. The first is referred to as the demographic dataset and collects information on the submitting agency, their vehicles, personnel, stations, medical equipment, protocols and medical direction. The second is referred to as the EMS dataset and collects information on the event or patient encounter.
CFOI data are collected by the Bureau of Labor Statistics (BLS) and contain information on fatal occupational injuries occurring in the U.S. To be included in CFOI, the decedent must have been employed at the time of the event, engaged in a legal work activity, or present at a site as a job requirement. Public and private sector non-institutionalized workers (i.e., wage and salary, self-employed, and volunteer) are included. CFOI excludes deaths that occurred during a worker’s normal commute to and from work and deaths related to occupational illnesses (e.g., lung disease or cancer).
The JDW contains Iowa traffic citation (charges and convictions) from the Iowa Judicial Branch courts database linked to crash data from the Iowa Department of Transportation. The data linkage is performed and the database is stored by the Iowa Department of Human Rights Division of Criminal and Juvenile Justice Planning (CJJP). The crash data includes information at the crash, driver/vehicle, and person levels. The justice data includes information on all charges, convictions, and corresponding sentences. The CJJP are also able to provide justice data based on requests (e.g., by age, years, or charge/conviction types).
The Iowa Youth Survey is a bi-annual survey conducted by the Iowa Department of Public Health’s Division of Behavioral Health in collaboration with the Iowa Department of Education, the Governor’s Office of Drug Control Policy, the Iowa Department of Human Rights’ Criminal and Juvenile Justice Planning and Statistical Analysis Center, and the Iowa Department of Human Services. Students in the 6th, 8th, and 11th grades across the state of Iowa answer questions about their attitudes and experiences regarding alcohol and other drug use and violence, and their perceptions of their peer, family, school, and neighborhood/community environments.
Since 1985, Iowa law has required all young children riding in motor vehicles to be properly protected through the use of child seats, booster seats, and/or seat belts. Iowa’s current child passenger safety law requires that:
- Children must ride in an appropriate rear-facing child safety seat until one year of age and at least 20 pounds.
- Children must ride in a child safety seat or a booster seat through the age of 5 years.
- Children ages 6 through 17 must ride in a booster seat and/or seat belt.
In order to measure compliance with the law and to direct educational efforts, observational child passenger restraint surveys are conducted annually by the University of Iowa Injury Prevention Research Center. See our infographic “Are Iowan children buckled up?”
The National Institute for Occupational Safety and Health’s (NIOSH) Iowa Fatality Assessment & Control Evaluation (FACE) Program collects basic information on all occupational fatalities in the state of Iowa. Additionally, the program collects in-depth information on select fatal injuries, and occasionally conducts detailed on-site investigations. Beginning in 1989, the program alerts employers, employees, and those who are self-employed, such as farmers, and makes recommendations and program suggestions to help prevent similar fatalities. The FACE website provides users with access to Iowa fatality investigation reports with both basic and in-depth information.
Iowa is one of 42 states funded by the Centers for Disease Control & Prevention to collect data on violent deaths for the National Violent Death Reporting System. Using a variety of source records, the IAVDRS gathers information on cause of death and contributing circumstances, and enters it into a national database. Community partners and researchers can use the data to contribute to a better understanding of violent deaths and develop strategies to prevent them.
Iowa data collection started for deaths that occurred beginning in calendar year 2015 and beyond. The department gathers reports from death certificates, medical examiner and law enforcement reports to identify circumstances that contribute to these types of violent deaths: homicides, suicides, deaths resulting from law enforcement intervention, unintentional firearm injury deaths, deaths of undetermined intent, and deaths resulting from terrorism.
The National Longitudinal Study of Adolescent to Adult Health is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the U.S. during the 1994-95 school year. The cohort has been followed into young adulthood, most recently from 2016-2018, to collect environmental, behavioral and biological data to track the emergence of chronic disease.
The National (Nationwide) Inpatient Sample is the largest publicly available all-payer inpatient health care database in the U.S., yielding national estimates of hospital inpatient stays.
