Modernizing the child fatality statute.

This bill updates Washington's child fatality review process to better identify preventable causes of death for children up to age 19. It requires local health departments to conduct confidential reviews of child deaths, protecting all private information collected from families, health staff, and medical providers. The law mandates that hospitals, schools, law enforcement, and other agencies must provide medical records and related data without charge for these reviews, while prohibiting the use of review materials in court proceedings. It also creates legal immunity for review participants and allows health departments to track trends through anonymized data. The policy change replaces outdated "mortality" terminology with "fatality" throughout the statute.
