Connecticut Violent Death Reporting System (CTVDRS)

Background Advisory Board and Meetings | Fact Sheets and Publications | Data Requests | Responses to Community Questions

The Connecticut Violent Death Reporting System (CTVDRS) was established in 2014 and is maintained through a cooperative agreement with the federal Centers for Disease Control and Prevention (CDC) and housed in the Connecticut Department of Public Health Office of Injury and Violence Prevention. This standardized database is part of the National Violent Death Reporting System (NVDRS) developed and funded by the CDC. Currently, NVDRS is implemented in all 50 states, the District of Columbia, and Puerto Rico. The goal of NVDRS is to provide states and communities with a clearer understanding of violent deaths. A thorough understanding of the complex circumstances surrounding these violent deaths will provide useful information in the development of prevention strategies. NVDRS provides insight into the potential points for intervention and ways to evaluate and improve violence prevention efforts.

The CTVDRS is an incident-based, relational database that combines information from multiple sources. Together, these multiple sources provide comprehensive context and answers to the questions (who, what, when, where, and why) leading to violent deaths.

Main data sources include:

Medical examiners' reports (including the toxicology reports),
Death certificates, and
Law enforcement reports (state and local)


Violent deaths:

According to the NVDRS definition, a violent death is a death that results from the intentional use of physical force or power, threatened or actual, against oneself, another person, or a group or community. Violent deaths include:

Deaths by legal intervention
Unintentional firearm injury deaths, and
Injury deaths of undetermined intent


All violent deaths occurring in Connecticut and violent deaths of Connecticut residents occurring out of state are included in the CTVDRS.


CTVDRS mission statement:

“Our mission is to collect, analyze, and disseminate accurate and comprehensive de-identified, aggregate Information of violent deaths in Connecticut to inform effective and efficient prevention strategies and public policies necessary for public safety and community well-being.”


CTVDRS Advisory Board

An advisory board was created at the beginning of the CTVDRS project to facilitate the development and monitor the ongoing progress of the project. The board meets quarterly and focuses on providing technical advice and, when necessary, offering strategic support in data procurement. In addition, the board will assist in the development and articulation of effective violent death prevention strategies including problem identification, policy development, and evaluation.
