Health facilities: hospitals; certain drug screens conducted in hospitals; require to include a test for substances determined by rule and to provide certain reporting. Amends 1978 PA 368 (MCL 333.1101 - 333.25211) by adding sec. 21525.

HB 5420 requires Michigan hospitals to include tests for specific substances in drug screens when diagnosing a drug overdose. It mandates that hospitals report anonymous test results to the Department of Health and Human Services (MDHHS), with results kept confidential and exempt from public disclosure. The MDHHS will define the list of "qualified substances" through rules (to be created within 180 days) and use the data to track trends and risk factors. This bill directly affects hospitals conducting overdose-related drug screens and the MDHHS, which will manage the reporting system and annual review of substances.
