Documenting Informed Consent
Structures informed consent documentation with risks, benefits, alternatives, and patient understanding confirmation for hospital procedures and treatments.
Why This Skill Exists
Informed consent is both an ethical obligation and a legal requirement for medical procedures and certain treatments. Failure to obtain or adequately document informed consent is the most common allegation in medical malpractice claims — present in approximately 30% of all suits, even when the underlying medical care was appropriate. The legal doctrine requires that a reasonable patient would want to know the information provided, and courts have increasingly held that the documentation must demonstrate a genuine exchange of information, not merely a signed form.
The Joint Commission requires documented informed consent for procedures and treatments that carry significant risk (RI.01.03.01). State laws vary on specific requirements, but all jurisdictions mandate disclosure of the nature of the procedure, material risks, expected benefits, alternatives (including no treatment), and verification that the patient understood and consented voluntarily. Hospitalists perform numerous bedside procedures (central lines, lumbar punctures, thoracentesis, paracentesis) and must obtain proper consent for each unless an emergency exception applies.
Checkpoint A: Pre-Draft Intake (Mandatory)
Before obtaining or documenting informed consent, confirm:
- What procedure or treatment requires consent? (Default: Any invasive procedure, blood transfusion, conscious sedation, high-risk medication initiation)
- Does the patient have decision-making capacity? (Default: Assess using the four-component standard — see managing-code-status-discussions skill)
- If the patient lacks capacity, who is the legally authorized surrogate? (Default: Follow state-specific surrogate hierarchy)
- Is this an emergency where consent cannot be obtained — life-threatening situation with no surrogate available? (Default: Document emergency exception if applicable)
- Does the patient require an interpreter for the consent discussion? (Default: Mandatory for patients with limited English proficiency — do not use family members for consent)
- Are there procedure-specific risks that must be disclosed? (Default: See procedure-specific risk tables below)
- Is the institutional consent form available and appropriate for this procedure? (Default: Use facility-approved form)
- Who will perform the procedure — and are they the ones obtaining consent (or is delegation appropriate per institutional policy)? (Default: The proceduralist or supervising physician obtains consent)
Documents to Request
- Institutional consent form for the specific procedure
- Procedure-specific risk disclosure checklist
- Patient's medical record for contraindications and comorbidities that affect risk
- Interpreter services contact (if needed)
- Healthcare proxy or POA documentation (if surrogate consent)
- State-specific informed consent statute reference
- Prior consent forms (if repeat procedure)
Step 1: Determine Consent Requirements
Not all medical actions require written informed consent. Use this framework:
| Level |
Examples |
Consent Type |
| Written consent required |
Central line, LP, thoracentesis, paracentesis, intubation (non-emergency), blood transfusion, conscious sedation, surgery |
Signed form + documented discussion |
| Verbal consent sufficient |
Peripheral IV, phlebotomy, urinary catheter, nasogastric tube, routine imaging |
Verbal consent noted in chart |
| Implied consent |
Vital signs, physical examination, routine medications |
Patient presents for care |
| Emergency exception |
Life-threatening emergency, patient lacks capacity, no surrogate available |
Proceed and document emergency exception |
Two-physician consent: Some institutions require two physicians to document consent for emergency procedures when the patient cannot consent and no surrogate is available.
Step 2: Conduct the Informed Consent Discussion
The legally required elements of informed consent (mnemonic: BRAIN-D):
B — Benefits
Explain the expected benefits in language the patient can understand:
- "This procedure will help us [specific clinical benefit]"
- Quantify when possible: "In most cases, this procedure successfully [outcome] about [X]% of the time"
R — Risks
Disclose material risks — those that a reasonable patient would want to know:
| Procedure |
Common Risks (> 1%) |
Serious Risks (< 1% but significant) |
| Central line |
Bleeding, infection, pain |
Pneumothorax, air embolism, arterial puncture, arrhythmia |
| Lumbar puncture |
Post-LP headache (10-30%), back pain, local bleeding |
Epidural hematoma, infection, cerebral herniation (if elevated ICP) |
| Thoracentesis |
Pain, cough, local bleeding |
Pneumothorax (2-5% without US), re-expansion pulmonary edema |
| Paracentesis |
Pain, local bleeding, fluid leak |
Bowel perforation, peritonitis, hemoperitoneum |
| Blood transfusion |
Febrile reaction, allergic reaction |
Hemolytic reaction, TRALI, TACO, infection transmission |
| Intubation |
Sore throat, hoarseness, dental injury |
Esophageal intubation, aspiration, hypoxia, cardiac arrest |
A — Alternatives
Always include alternatives, including the alternative of no treatment:
- "Instead of [procedure], we could [alternative approach]"
- "If we choose not to do this procedure, the likely outcome would be [consequence]"
I — Indication
Explain why this procedure is recommended:
- "We are recommending this because [clinical rationale linked to the patient's specific condition]"
N — Nature of the Procedure
Describe what will happen in plain language:
- "During this procedure, I will [step-by-step description without jargon]"
- "It typically takes about [duration]"
- "You will be [position, awake/sedated]"
D — Decision
Confirm the patient's decision:
- "Do you have any questions?"
- "Do you understand what we discussed?"
- "Do you agree to proceed with this procedure?"
Step 3: Document the Consent
Use this structured documentation template:
INFORMED CONSENT DOCUMENTATION
Date/Time: [Timestamp]
Procedure: [Full procedure name]
Performing physician: [Name, credentials]
Patient capacity: [Has capacity / Lacks capacity — basis for determination]
Consent obtained from: [Patient / Surrogate — name, relationship, legal authority]
Interpreter used: [Yes — language, interpreter name/ID / No — patient speaks English]
Discussion included:
1. Nature: [Procedure description as explained to patient]
2. Indication: [Why procedure is recommended for this patient]
3. Benefits: [Expected benefits discussed]
4. Risks: [Specific risks discussed — list each]
5. Alternatives: [Alternatives discussed including no treatment]
6. Questions: [Patient questions and responses — or "Patient had no questions"]
Patient understanding: Patient (or surrogate) verbalized understanding of
the procedure, risks, benefits, and alternatives.
Voluntary consent: Patient (or surrogate) consented voluntarily
without coercion.
Signed consent form: On file in medical record.
[Physician signature, date, time]
Step 4: Handle Special Consent Situations
Surrogate consent (patient lacks capacity):
- Identify the legally authorized surrogate per state hierarchy (typically: healthcare proxy > spouse > adult child > parent > sibling)
- Document the basis for the patient's incapacity
- Document the surrogate's relationship and legal authority
- The surrogate must make decisions based on the patient's known wishes (substituted judgment) or, if wishes are unknown, the patient's best interest
Emergency exception (implied consent):
- Document that the procedure is medically necessary to prevent death or serious harm
- Document that the patient lacks capacity to consent
- Document that no surrogate is available despite reasonable efforts to locate one
- Document the specific efforts made to find a surrogate
- Proceed with the procedure and obtain consent from the surrogate as soon as one is available
Patient refusal:
- Document that risks of refusing were explained (including potential death if applicable)
- Document that the patient has capacity to refuse
- Document the patient's stated reason for refusal
- Do not coerce — respect the autonomous decision of a patient with capacity
- Offer to revisit the discussion if the patient changes their mind
Minor patients:
- Parent or legal guardian provides consent
- Emancipated minors and mature minors may consent for themselves per state law
- Emergency exception applies to minors as well
Checkpoint B: Post-Draft Alignment (Mandatory)
Before proceeding with any procedure:
- Is the signed consent form in the medical record?
- Does the consent note document all required elements (nature, risks, benefits, alternatives)?
- Was an interpreter used for non-English-speaking patients?
- Has the patient's understanding been verified (not just signature obtained)?
- Is there a documented time-out verifying correct patient, procedure, and site?
Quality Audit
Guidelines
- Informed consent is a conversation, not a form — the signed document memorializes the discussion but does not replace it
- Never obtain consent from a patient who is sedated, in severe pain, or otherwise unable to meaningfully participate
- Use plain language at a 6th-grade reading level — avoid medical jargon in the consent discussion
- Do not delegate consent to someone who will not perform or supervise the procedure unless institutional policy explicitly allows it
- For recurring procedures (e.g., serial paracentesis), verify whether institutional policy requires new consent each time or allows a blanket consent with a defined expiration
- Document specific risks discussed, not just "risks and benefits discussed" — specificity is the key legal protection
- If a patient initially refuses and later agrees, document both the refusal and the subsequent consent with timing
- Consent forms have an institutional validity period (usually 30 days) — verify that the form is current before the procedure
