The bill seeks to address the issue of fentanyl testing in hospital emergency departments. It requires the Secretary of Health and Human Services to complete a study within a year to determine the frequency, costs, benefits, and risks of testing for fentanyl in emergency departments during overdoses. The study will also assess how such testing may impact patient experience, confidentiality, privacy, and the patient-physician relationship. Based on the study's results, the Secretary will issue guidance on whether emergency departments should implement fentanyl testing, how hospitals can ensure clinicians are aware of substances being tested, and the potential effects on future overdose risk and health outcomes.
