EMS Systems, Roles & Medical-Legal
Your role in the EMS system, scope of practice, and the consent and legal rules that govern care.
Your Role & Safety
The EMT's first priority on any scene is SAFETY — your own, your crew's, the patient's, then bystanders, in that order. You can't help anyone if you become a patient.
Scene size-up: ensure scene safety, use BSI/PPE (standard precautions), identify the mechanism of injury or nature of illness, count patients, and call for additional resources before you commit.
Consent
• EXPRESSED CONSENT — a competent adult agrees to care (must be informed). • IMPLIED CONSENT — assumed for an unconscious or incapacitated patient who would reasonably want care. • MINORS — generally require parent/guardian consent; implied consent applies in emergencies.
A competent adult has the RIGHT TO REFUSE care. Document refusals carefully and have the patient sign.
Legal Duties
• DUTY TO ACT — your obligation to respond/provide care while on duty. • NEGLIGENCE requires four elements: duty, breach of duty, damages, and causation. • ABANDONMENT — ending care without ensuring an equal/higher level of care takes over. • HIPAA protects patient confidentiality.
The standard is to act as a reasonable, prudent EMT with similar training would in the same situation.
