Assembly Bill 571 establishes a statewide Parkinson's disease registry under the Department of Population Health Sciences at the University of Wisconsin-Madison. The bill mandates that healthcare providers report data on patients diagnosed with Parkinson's disease or related parkinsonisms to the registry, which will collect information on the incidence, prevalence, and outcomes associated with these conditions. If a patient opts out of participating in the registry, only the diagnosis will be reported. The bill also requires the creation of a public website to disseminate annual reports and relevant data about Parkinson's disease in Wisconsin.

Additionally, the bill includes provisions for confidentiality, ensuring that any identifying information about individuals reported to the registry is protected. The Department of Population Health Sciences is authorized to enter into agreements to share data with other registries and researchers, provided that confidentiality is maintained. The bill also outlines the responsibilities of the Department of Health Services in assisting with the registry's establishment and maintenance. Overall, this legislation aims to enhance the understanding and management of Parkinson's disease in Wisconsin through systematic data collection and reporting.
