CDC Data Sources

Hospital Inpatient Discharge Data
Medical information about discharges includes up to seven diagnoses and up to four surgical and nonsurgical operations and procedures. Medical data are coded to the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM). Basic demographic information is also included for patients discharged. Medical cost information is not collected in this survey. 

National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP)
NEISS-AIP provides nationally representative data about all types and causes of nonfatal injuries treated in United States hospital emergency departments. CDC uses NEISS-AIP data to generate national estimates of nonfatal injuries, including those related to suicide.

National Hospital Ambulatory Medical Care Survey
The National Hospital Ambulatory Medical Care Survey collects data on the utilization and provision of ambulatory care services in hospital emergency and outpatient departments. 

National Violent Death Reporting System
CDC has established the National Violent Death Reporting System (NVDRS) and has funded 17 states to gather, share, and link state-level data on violent deaths, including suicides. NVDRS provides CDC and participating states with a more complete understanding of violent death. This enables policy makers and community leaders to make informed decisions about violence prevention programs, including those that address suicide.

The National Vital Statistics System
The National Vital Statistics System is the oldest and most successful example of inter-governmental data sharing. This system includes nationwide data on deaths due to all causes, including suicide.

WISQARS
WISQARS (Web-based Injury Statistics Query and Reporting System, pronounced "whiskers") is an interactive database providing access to national injury-related morbidity (NEISS-AIP) and mortality data (Vital Statistics). These data are useful for research and for making informed public health decisions.

Youth Risk Behavior Surveillance System
CDC's Youth Risk Behavior Surveillance System monitors health risk behaviors that contribute to the leading causes of death and disability among young people in the United States, including suicide.

Other Federal Data Sources

Drug Abuse Warning Network
The Drug Abuse Warning Network is a public health surveillance system that monitors drug-related hospital emergency department visits and drug-related deaths for the purpose of tracking the impact of drug use, misuse, and abuse in the United States. 

Other Federal Data Sources

The American Association of Suicidology
The goal of the American Association of Suicidology (AAS) is to understand and prevent suicide. The Research Division of AAS is dedicated to advancing knowledge about suicidal behavior through science. A description of research projects is available on the AAS Web site.
