Birth Defects Information System

Back to BDMA program page

The Birth Defects Information System (BDIS) statute was enacted in 2004 to establish and maintain an information system containing data on the cause, treatment, prevention, and cure of major birth defects. The BDIS actively collects information from hospital and clinic charts of infants diagnosed with certain conditions present at birth and identified in the first year of life. The BDIS database started in 2006 with infants born or treated in Hennepin and Ramsey Counties. As of June 2013, BDIS monitors approximately 82 percent of Minnesota births for the presence of one of 46 birth defects.

Policy and administrative direction continues to be obtained from a multi–disciplinary Birth Defects Work Group that includes representatives and experts in epidemiology, medicine, insurance, health maintenance organizations, genetics, parents of children with birth defects, voluntary organizations and local public health.

How is the information used?

  • Monitor incidence trends of birth defects to detect potential public health problems, predict risks, assist in response to birth defects clusters, and detect changes in birth defects rates
  • Evaluate impact of primary prevention efforts designed to improve health outcomes
  • More accurately target intervention, prevention, and services for communities, patients, and their families
  • Inform health professionals and citizens of the prevalence of, risks for, and prevention of birth defects
  • Assure that families are connected with appropriate services in close partnership with local public health
  • Conduct scientific investigations and surveys of the causes, mortality, methods of treatment, prevention, and cure for birth defects
  • Modify, as necessary, the birth defects information system through demonstration projects
