National Inpatient Sample (NIS)
The National (Nationwide) Inpatient Sample (NIS) is part of a family of databases and software tools developed for the Healthcare Cost and Utilization Project (HCUP). The NIS is the largest publicly available all-payer inpatient health care database in the United States, yielding national estimates of hospital inpatient stays. Beginning in 2012, the NIS was redesigned. It was formerly a sample of hospitals, and all discharges from those hospitals were retained. The new NIS starting with 2012 data is a sample of discharges from all hospitals participating in HCUP.
Beginning with the 2012 data year, HCUP's NIS is a 20 percent sample of discharges from all community hospitals participating in HCUP, excluding rehabilitation and long-term acute care hospitals. The NIS covers all patients, including individuals covered by Medicare, Medicaid, or private insurance, as well as those who are uninsured.
Occupational Injuries and Illness: Industry Data
The Survey of Occupational Injuries and Illnesses is a Federal/State program in which employer's reports are collected annually from about 176,000 private industry establishments and processed by State agencies cooperating with the Bureau of Labor Statistics. Summary information on the number of injuries and illnesses is copied by these employers directly from their recordkeeping logs to the survey questionnaire. The questionnaire also asks for the number of employee hours worked (needed in the calculation of incidence rates) as well as its average employment (needed to verify the unit's employment-size class).
The survey excludes all work-related fatalities as well as nonfatal work injuries and illnesses to the self employed; to workers on farms with 10 or fewer employees; to private household workers; and, nationally, to federal, state, and local government workers.
National Data Archive on Child Abuse and Neglect (NDACAN)
A resource since 1988, the National Data Archive on Child Abuse and Neglect (NDACAN) promotes scholarly exchange among researchers in the child maltreatment field. NDACAN acquires microdata from leading researchers and national data collection efforts and makes these datasets available to the research community for secondary analysis.
NCANDS is a voluntary data collection system that gathers information from all 50 states, the District of Columbia, and Puerto Rico about reports of child abuse and neglect. NCANDS was established in response to the Child Abuse Prevention and Treatment Act of 1988. The data are used to examine trends in child abuse and neglect across the country, and key findings are published in our Child Welfare Outcomes Reports to Congress and annual Child Maltreatment reports.
National Automotive Sampling System (NASS)
The National Automotive Sampling System (NASS) was established in 1979 as part of a nationwide effort to reduce motor vehicle crashes, injuries, and deaths on our highways. NASS collects crash data to help government scientists and engineers analyze motor vehicle crashes and injuries. NASS has detailed data on a representative random sample of minor, serious, and fatal crashes involving passenger cars, pickup trucks, vans, large trucks, motorcycles, and pedestrian crashes.
NASS has two parts: the Crashworthiness Data System (CDS) and the General Estimates System (GES). Both systems select cases from police accident reports at police agencies within randomly selected areas of the country. These areas are counties and major cities that represent all areas of the United States.
National Ambulatory Medical Care Survey (NAMCS)
The 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. Physicians in the specialties of anesthesiology, pathology, and radiology are excluded from the survey. The survey was conducted annually from 1973 to 1981, in 1985, and annually since 1989.
Survey of Sexual Violence (SSV)
The Survey of Sexual Violence (SSV) is part of the BJS National Prison Rape Statistics Program to gather mandated data on the incidence and prevalence of sexual assault in correctional facilities under the Prison Rape Elimination Act of 2003 (PREA; P.L. 108- 79). This is an administrative data collection based on allegations of sexual victimization by other inmates or staff that are reported to correctional authorities. The collection includes an enumeration of incidents reported to state prison systems, state juvenile correctional systems, the federal prison system, the Bureau of Immigration and Customs Enforcement (ICE), the U.S. military, and a sample of jail jurisdictions, privately operated adult prisons and jails, and facilities in Indian country. Additional information is collected on substantiated incidents on the victim (s), perpetrator(s), characteristics of the incident, and outcomes.
National Hospital Ambulatory Medical Care Survey (NHAMCS)
The 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. Findings are based on a national sample of visits to the emergency departments and outpatient departments of noninstitutional general and short-stay hospitals. Hospital-based ambulatory surgery centers were first added to this study in 2009, and freestanding ambulatory surgery centers were added in 2010.
Firefighter Fatalities in the U.S.
The U.S. Fire Administration tracks and collects information on the causes of on-duty firefighter fatalities that occur in the United States. They conduct an annual analysis to identify specific problems so that they may direct efforts toward finding solutions that will reduce firefighter fatalities in the future. This information is also used to measure the effectiveness of programs directed toward firefighter health and safety.
Aviation Accident Database & Synopses
The National Transportation Safety Board (NTSB) aviation accident database contains information from 1962 and later about civil aviation accidents and selected incidents within the United States, its territories and possessions, and in international waters. Generally, a preliminary report is available online within a few days of an accident. Factual information is added when available, and when the investigation is completed, the preliminary report is replaced with a final description of the accident and its probable cause. Full narrative descriptions may not be available for dates before 1993, cases under revision, or where NTSB did not have primary investigative responsibility.
Behavioral Risk Factor Surveillance System (BRFSS)
In 1984, the Centers for Disease Control and Prevention (CDC) initiated the state-based Behavioral Risk Factor Surveillance System (BRFSS)--a cross-sectional telephone survey that state health departments conduct monthly over landline telephones and cellular telephones with a standardized questionnaire and technical and methodological assistance from CDC. BRFSS is used to collect prevalence data among adult U.S. residents regarding their risk behaviors (e.g., drinking and driving, seatbelt use, alcohol consumption) and preventive health practices that can affect their health status. Respondent data are forwarded to CDC to be aggregated for each state, returned with standard tabulations, and published at year's end by each state. By collecting behavioral health risk data at the state and local level, BRFSS has become a powerful tool for targeting and building health promotion activities.
Drug Abuse Warning Network (DAWN)
The Drug Abuse Warning Network (DAWN) is a public health surveillance system that monitors drug-related hospital emergency department visits in order to report on the impact of drug use, misuse, and abuse in metropolitan areas and across the nation. DAWN was established in 1972 by the Drug Enforcement Administration (DEA) to track emergency department (ED) visits caused by drug abuse in order to identify the drugs being abused, determine patterns in selected metropolitan areas and changing trends across the country, including the detection of new substances of abuse and new combinations.
Nonfatal Cases Involving Days Away From Work: Selected Characteristics
Case and Demographic Characteristics for Work-related Injuries and Illnesses Involving Days Away From Work
Besides injury and illness counts, survey respondents also are asked to provide additional information for a subset of the most serious nonfatal cases logged, namely, those that involved at least 1 day away from work, beyond the day of injury or onset of illness. Employers answer several questions about these cases, including the demographics of the worker disabled, the nature of the disabling condition, and the event and source producing that condition.
National Vital Statistics System (NVSS)
The National Vital Statistics System is the oldest and most successful example of inter-governmental data sharing in Public Health and the shared relationships, standards, and procedures form the mechanism by which NCHS collects and disseminates the Nation's official vital statistics. This system includes nationwide data on deaths due to all causes, including suicides, drug-poisoning, drowning, etc.
Analysis & Information - Crash Statistics
Crash Statistics are summarized statistics for large trucks and buses involved in fatal and non-fatal crashes that occurred in the United States and territories.
These statistics are derived from two sources: the Fatality Analysis Reporting System (FARS) and the Motor Carrier Management Information System (MCMIS). Crash Statistics contain information that can be used to identify safety problems in specific geographical areas or to compare state statistics to the national crash figures.
WISQARS Fatal Injury Reports
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.
WISQARS fatal injury reports include:
- Fatal injury reports showing the total number of injury deaths and death rates by intent and mechanism (cause) of injury, geographic region/state, race/ethnicity, sex and age.
- Leading cause of death reports showing the impact of injury-related deaths in the United States compared to other leading causes of death.
- Years of potential life lost (YPLL) reports showing the impact of premature death resulting from injury compared to other leading causes of premature death.
- Color-coded fatal injury maps showing patterns of county-level injury death rates across geographic areas (national, regional, and state level).
- Cost of injury reports providing cost estimates for injury deaths.
Compressed Mortality File - Underlying Cause of Death - CDC WONDER
The Compressed Mortality data include mortality and population counts for all U.S. counties for the years 1968 to 2013. Counts and rates of death can be obtained by underlying cause of death, state, county, age, race, sex, and year. Compressed Mortality data are updated annually.
Infant Deaths - CDC WONDER
This data collection provides counts and rates for deaths of children under 1 year of age, occuring within the United States to U.S. residents. Information from death certificates has been linked to corresponding birth certificates. Data are available by county of mother's residence, child's age, underlying cause of death, gender, birth weight, birth plurality, birth order, gestational age at birth, period of prenatal care, maternal race and ethnicity, maternal age, maternal education and marital status. The data are produced by the National Center for Health Statistics.
Mortality Multiple Cause of Death
Mortality data from the National Vital Statistics System (NVSS) are a fundamental source of demographic, geographic, and cause-of-death information. This is one of the few sources of health-related data that are comparable for small geographic areas and are available for a long time period in the United States. The data are also used to present the characteristics of those dying in the United States, to determine life expectancy, and to compare mortality trends with other countries.
Multiple Cause of Death Data - CDC WONDER
The Multiple Cause of Death data available on CDC WONDER are county-level national mortality and population data. Data are based on death certificates for U.S. residents. Each death certificate contains a single underlying cause of death, up to twenty additional multiple causes, and demographic data. The number of deaths, crude death rates and age-adjusted death rates can be obtained by place of residence (United States national, state, and county), age group, race, Hispanic ethnicity, gender, year and month of death, weekday of death, place of death, autopsy status, and underlying and multiple cause of death (4-digit ICD-10 codes, 113 selected causes of death, 130 selected causes of death for infants, injury causes, or drug / alcohol induced causes of death). Two archive datasets offer subsets of these data.
National Crime Victimization Survey (NCVS)
The National Crime Victimization Survey (NCVS) is the nation's primary source of information on criminal victimization conducted by the U.S. Census Bureau for the Bureau of Justice Statistics (BJS). Each year, data are obtained from a nationally representative sample of about 90,000 households comprising nearly 160,000 persons on the frequency, characteristics and consequences of criminal victimization in the United States. Each household is interviewed twice during the year.
The survey enables BJS to estimate the likelihood of victimization by rape or sexual assault, robbery, aggravated and simple assault, theft, household burglary, and motor vehicle theft for the population as a whole as well as for segments of the population such as women, the elderly, members of various racial or ethnic groups, city dwellers, and other groups. The NCVS provides the largest national forum for victims to describe the impact of crime and characteristics of violent offenders.
National Fire Incident Reporting System (NFIRS)
The National Fire Incident Reporting System (NFIRS) is the world's largest, national, annual database of fire incident information. 50 states and the District of Columbia report NFIRS data. This data includes fatalities to both firefighters and other fire victims.The NFIRS is a reporting standard that fire departments use to uniformly report on the full range of their activities, from fire to emergency medical services (EMS) to equipment involved in the response. The NFIRS database comprises about 75 percent of all reported fires that occur annually.
National Violent Death Reporting System (NVDRS)
The National Violent Death Reporting System (NVDRS) is a state-based surveillance system that links data from law enforcement reports, coroners and medical examiners reports, vital statistics records, and crime laboratories to assist each participating state in designing and implementing tailored prevention and intervention efforts.
NVDRS defines a death due to violence as "a death resulting from the intentional use of physical force or power against oneself, another person, or against a group or community." NVDRS collects information about homicides, suicides, deaths by legal intervention-excluding executions-and deaths of undetermined intent. In addition, information about unintentional firearm injury deaths (i.e., the individual did not intend to discharge the firearm) is collected, although these deaths are not considered violent deaths by the above definition. Deaths are included if their underlying causes (ICD codes) are included in these categories.
Nationwide Emergency Department Sample (NEDS)
The Nationwide Emergency Department Sample (NEDS) is part of a family of databases and software tools developed for the Healthcare Cost and Utilization Project (HCUP). The NEDS is the largest all-payer emergency department (ED) database in the United States, yielding national estimates of hospital-based ED visits. Unweighted, it contains data from approximately 30 million discharges each year. Weighted, it estimates roughly 130 million ED visits.
Sampled from the State Inpatient Databases (SID) and State Emergency Department Databases (SEDD), HCUP's NEDS that can be used to create national and regional estimates of ED care. The SID contain information on patients initially seen in the ED and then admitted to the same hospital. The SEDD capture information on ED visits that do not result in an admission (i.e., treat-and-release visits and transfers to another hospital).
State Ambulatory Surgery and Services Databases (SASD)
The State Ambulatory Surgery and Services Databases (SASD) are part of the family of databases and software tools developed for the Healthcare Cost and Utilization Project (HCUP). The SASD include encounter-level data for ambulatory surgeries and may also include various types of outpatient services such as observation stays, lithotripsy, radiation therapy, imaging, chemotherapy, and labor and delivery. The specific types of ambulatory surgery and outpatient services included in each SASD vary by State and data year. All SASD include data from hospital-owned ambulatory surgery facilities. In addition, some States include data from nonhospital-owned facilities.
State Emergency Department Databases (SEDD)
The State Emergency Department Databases (SEDD) are part of the family of databases and software tools developed for the Healthcare Cost and Utilization Project (HCUP). The SEDD capture emergency visits at hospital-affiliated emergency departments (EDs) that do not result in hospitalization. Information about patients initially seen in the ED and then admitted to the hospital is included in the State Inpatient Databases (SID). The SEDD files include all patients, regardless of payer, providing a unique view of ED care in a State or in a defined market over time.
