This bill, known as Tyler's Law, mandates the Secretary of Health and Human Services (HHS) to undertake a comprehensive study regarding fentanyl testing in hospital emergency departments for patients experiencing an overdose. The study will assess the frequency and costs associated with fentanyl testing, alongside its potential benefits and risks for patients. Furthermore, the study will examine how fentanyl testing impacts the patient experience, including aspects like confidentiality of personal health information and the patient-physician relationship. Within six months of completing this study, HHS is directed to issue guidance based on its findings. This guidance will determine whether routine fentanyl testing should be implemented in emergency departments for overdose cases. It will also provide recommendations on how hospitals can ensure clinicians are aware of all substances being tested for in routine drug screens, and how fentanyl testing might influence future overdose risk and overall health outcomes for patients.
