Legal & Ethical Foundations

Category: Foundations Last updated: 2026-04-05 San Juan College EMT-B Program — New Mexico

Overview

EMT-B practice is bounded by law, ethics, and the specific scope of practice defined by your state's EMS bureau. Understanding the legal framework is not about avoiding lawsuits — it is about knowing when you have the authority and obligation to act, when you must defer, and when you must stop. Most providers who face legal liability do so not from malicious acts but from documentation failures, scope violations, or abandonment that happened during a chaotic call.

The core principle: a patient's autonomy and dignity are paramount, but they do not override your obligation to act when the patient lacks the capacity to protect themselves.

Every intervention you perform on a patient requires consent. The type of consent changes based on the patient's condition and capacity.

  • The patient actively agrees to treatment after being informed
  • Requirements for valid expressed consent:
  • Capacity: Patient is a competent adult (18+), alert and oriented, not impaired by drugs, alcohol, illness, or injury
  • Information: Patient has been told their condition, the proposed treatment, the risks of the treatment, and the risks of refusing
  • Voluntariness: Consent is given freely, without coercion
  • A patient saying "okay, go ahead" after you explain what you are doing is expressed consent for that intervention
  • Consent must be ongoing — if a patient withdraws consent mid-treatment, you must stop
  • Applies when the patient is unable to consent (unconscious, unresponsive, profoundly altered mental status)
  • The legal presumption: a reasonable person would want life-saving treatment if they were able to consent
  • Covers the gap between a patient who cannot express consent and the need to act immediately
  • Does not authorize experimental or clearly unwanted treatment — it authorizes the standard of care for the patient's condition
  • Expires the moment the patient regains capacity: if an unconscious patient regains consciousness and refuses treatment, you must honor that refusal
  • Applies to patients under a legal hold, a court order for treatment, or in police custody under a specific order
  • Rare in the field; requires specific legal documentation
  • EMT-B does not typically initiate this — law enforcement will notify you when a patient is under a legal hold

Children cannot consent to or refuse medical treatment on their own behalf.

  • Parent or legal guardian must consent for treatment and transport of a minor
  • If a parent refuses treatment for a child: valid only if no life threat is present. If a life threat exists, treat and transport under implied consent regardless of parent refusal
  • Emancipated minor: Legally considered an adult for consent purposes — married, in military service, financially independent by court order, or pregnant (varies by state). NM law recognizes emancipated minors; verify documentation if possible
  • Guardian not available: Make reasonable attempts to contact; if cannot reach and a life threat exists, treat under implied consent and transport to nearest appropriate facility. Contact Medical Control

Refusal of Care

Competent adults have the right to refuse any or all treatment or transport, including treatment that would clearly benefit them. This is uncomfortable but fundamental.

For a refusal to be legally valid: 1. Patient has decision-making capacity (oriented, not impaired, understands situation) 2. Patient has been informed of their condition, proposed treatment, and the risks of refusing 3. Patient's decision is voluntary (not under coercion) 4. Patient signs a refusal form; refusal is witnessed

If any of these conditions is not met, the refusal is not legally valid.

See refusal-of-care for full protocol including documentation requirements, pediatric refusal, and involuntary transport under NM statute 24-10B-9.1.

Duty to Act

Once you are dispatched and en route, you have a legal and ethical duty to act — to provide the standard of care for that patient's condition, within your scope.

Duty to act exists because: - The system has sent you as the designated resource - The patient (or caller) is relying on your response - Other resources may have been held or canceled based on your response

Duty to act does not mean you must enter an unsafe scene. It does not require you to exceed your scope. It does mean that once you are the assigned resource for a patient, you cannot simply not respond, not assess, or not act without a valid reason.

Abandonment

Abandonment is ending your care of a patient without: 1. Transferring to an equally or higher-level provider, OR 2. Obtaining the patient's competent, informed consent to stop care

Abandonment examples: - Leaving a patient on scene without arranging ongoing care - Transferring care to a bystander with no medical training - Leaving a hospital hallway without completing the handoff to hospital staff - Canceling an ALS unit and leaving before ALS arrives (when ALS was needed)

You cannot transfer care to a lower level of provider without patient consent. An EMT-B cannot hand off a critical patient to an EMR or first responder and leave unless the patient accepts that arrangement.

Negligence

Negligence is failure to meet the standard of care that results in patient harm. Four elements must all be present for legal negligence:

Element Definition Example
Duty You had a legal obligation to care for this patient Dispatched, en route, or on scene
Breach You failed to meet the standard of care Did not administer aspirin to an ACS patient with no contraindications
Causation Your breach caused or contributed to the harm Patient had a larger MI because aspirin was not given
Damages The patient suffered actual harm Permanent cardiac damage, death

All four elements must be provable. If any one is absent, legal negligence cannot be established. This is why documentation matters: a thorough PCR that shows assessment findings, contraindications considered, and rationale for decisions defends against breach allegations.

Scope of Practice

Scope of practice is the list of assessments and interventions you are legally authorized to perform, defined by: - NM EMS Bureau regulations - Your level of licensure (EMT-B) - Your agency's protocols (which may be more restrictive than state scope) - Your medical director's standing orders

You cannot exceed scope even if the patient would benefit. This protects you legally and protects the patient from interventions you are not trained or equipped to perform safely.

If you believe a patient needs an intervention beyond your scope: 1. Request ALS upgrade / intercept 2. Provide the best care within your scope 3. Transport rapidly 4. Consult online medical direction if unsure

Common scope confusion areas for EMT-Bs: - IV/IO access: ALS scope in NM (EMT-B does not start IVs) - Albuterol nebulizer: in scope for EMT-B in NM with standing orders — verify with agency protocol - Nitroglycerin: EMT-B may assist patient with their own prescribed NTG; does not carry or administer independently - Activated charcoal: in scope but declining in use — require online medical direction in many NM systems

Documentation: If It Wasn't Written, It Didn't Happen

The Patient Care Report (PCR) is both a medical record and a legal document. It must be accurate, complete, and objective.

What Goes in a PCR

  • Dispatch information: time, location, nature of call
  • Scene assessment: scene safety, MOI/NOI, number of patients, hazards
  • Patient information: demographics, chief complaint, history (SAMPLE/OPQRST)
  • Assessment findings: all vital signs (with times), physical exam findings, mental status, AVPU/GCS
  • Interventions: what was done, when, by whom, and the patient's response
  • Refusals: full documentation if patient refused any care (see above)
  • Transfer of care: who received the patient at the hospital, time, report given

Documentation Standards

  • Document what you observed and what you did — not interpretations or diagnoses
  • Record vital signs with timestamps; multiple sets show trending
  • If something is not done that should have been: document why (contraindication, patient refusal, time constraint)
  • Do not alter a PCR after submission without following your agency's amendment procedure
  • Falsifying a PCR is a criminal act and results in license revocation

Confidentiality and HIPAA

The Health Insurance Portability and Accountability Act (HIPAA) governs protected health information (PHI).

  • You cannot share patient information with people who have no treatment-related need to know — including family members, coworkers not on the call, social media, and media
  • Permitted sharing: other healthcare providers in the treatment chain (hospital staff, ALS crew), quality assurance review, legally mandated reporting (certain communicable diseases, child/elder abuse), and law enforcement under specific conditions
  • In San Juan County: child abuse reporting is mandatory. Elder abuse reporting is mandatory. Contact medical control or your supervisor for guidance.
  • Even discussing a patient's case in public (e.g., in a restaurant) where others can overhear is a HIPAA violation

Do Not Resuscitate (DNR) Orders

A valid DNR order or advance directive instructs EMS not to initiate resuscitation. See dnr-death-determination for complete protocol including how to verify a valid DNR, MOST forms, and withholding resuscitation criteria.

Key principle: you cannot ignore a valid DNR. A valid DNR is legally binding. Ignoring it is battery — unwanted touching — regardless of the outcome.

  • refusal-of-care — full adult and pediatric refusal protocol; involuntary transport
  • dnr-death-determination — advance directives, DNR verification, withholding resuscitation
  • ems-system — medical direction; how scope of practice is set and enforced
