The Office includes three sections: State Registrar/Vital Records, Health Analytics, and Informatics Architecture.

  • The State Registrar/Vital Records Section carries out state vital statistics functions as established in Chapter 69, Wisconsin Statutes. The Internal Operations Unit manages all vital records system operations and registers all vital events: births, deaths, fetal deaths, marriages, divorces, declarations of domestic partnership, and terminations of domestic partnership. The External Operations Unit trains and supports vital records business partners in birthing hospitals, birthing centers, funeral homes, coroner and medical examiner offices, and county offices to assure that field operations are consistent with vital records policies and that procedures are followed uniformly throughout the state. The Customer and Special Services Unit provides all public customer services; for example, copies of vital records; it also manages all other special services.
  • The Health Analytics Section provides analysis of health data, including linked data bases and reports, based on its data collection systems and other data sources.  The section maintains the Wisconsin Cancer Reporting System (cancer registry), the Pregnancy Risk Assessment Monitoring System (PRAMS), and the Wisconsin Violent Death Reporting System; and conducts two population surveys, the Behavioral Risk Factor Survey and the Family Health Survey.  The section provides demographic data and constructs population estimates. The section also provides data on health care providers and health care services to the Department for epidemiological and administrative use. The section develops and maintains WISH, a Web-based interactive query system providing local and statewide health information.
  • The PHIN Coordinator/Informatics Architecture Section focuses on integrating information contributed by the public health community and its partners so that it can be appropriately and quickly retrieved, analyzed, and shared. The Public Health Information Network (PHIN) will support the entire spectrum of public health activities in the state through disease detection and monitoring, data analysis, secure network communications, emergency alert and response, and knowledge management.
  • The Chief Medical Officer for the Office is responsible for helping define the use of clinical data to promote the improvement of public health in Wisconsin. The OHI CMO works in conjunction with other CMOs in the Division of Public Health to focus the analytics and data needs from a clinical perspective.

The Office of Health Informatics has key relationships with other entities in the Department, local health departments, universities, health care providers, and federal public health agencies.
