: Clinicians can find themselves balancing rights, consent, and duty of care when law enforcement officers (LEOs) request blood alcohol testing.
Although the Fourth Amendment protects individuals from unreasonable searches, state implied consent laws mean that, simply by operating a vehicle on a public road, a driver automatically agrees to take a chemical test (like a blood, breath, or urine test) if an LEO has probable cause to believe they were driving under the influence.
In addition, in 2019, the Supreme Court ruled that warrantless blood draws may be permissible in exigent circumstances. Notably, legality hinges on the context of the situation, not solely on the patient’s ability to consent.
Ethically informed collaboration safeguards patients and protects your institution. Best practices for clinicians include:
▪️Establishing clear, discoverable policies and procedures
▪️Considering LEO-trained staff for evidence collection
▪️Documenting all LEO interactions in the medical record
▪️Knowing your state and local laws
▪️Including legal, ethics, and risk management teams
