How to Write an Informed Consent Form: Step-by-Step Guide with Examples
Reviewed by ConsentCollect Compliance Team
Key Takeaways: Drafting Consent Forms
- Plain Language is Mandatory: Write your documents at a sixth to eighth-grade reading level. Check your text using our free readability checker to avoid complex medical jargon that confuses signers.
- The Anatomy is Structured: Every valid form needs a header, a concise Key Information summary, a detailed procedure description, organized risk lists, and clear signature blocks.
- Avoid Legal Trap Clauses: Do not include exculpatory language that makes patients waive their rights. These clauses are illegal under federal rules and cause immediate review rejections.
- Different Methods for Different Budgets: You can use our free PDF builder to write and print traditional paper forms, or upgrade to our paid eConsent system for automated tracking, quizzes, and digital signatures.
- Automate Compliance: Use ConsentCollect's Clinical Auditor to scan your text in one click. It flags missing disclosures, legal vulnerabilities, and readability errors, helping you fix them instantly to prevent Institutional Review Board (IRB) delays.
Drafting an informed consent form is one of the most challenging writing tasks in healthcare and clinical research. You must balance two opposing goals. On one side, your legal and compliance teams want to include detailed disclosures to protect the organization from liability. On the other side, patients need simple, clear explanations so they can make an informed choice.
Most consent forms fail because they are written like dense legal contracts. When a document is filled with complex medical jargon and long sentences, patients cannot understand it. This creates major problems. It increases the risk of malpractice disputes, causes patient anxiety, and leads to weeks of back-and-forth reviews with Institutional Review Boards (IRBs).
This guide provides a practical, step-by-step tutorial on how to write a compliant, reader-friendly consent form. We review the core rules of patient education, analyze the anatomy of a form using a gallbladder removal example, explore research-specific clauses, and show how digital tools like ConsentCollect can simplify your compliance workflow. For a detailed look at the clinical process of obtaining consent, see our guide on how to get informed consent from patients.
#1. The Three Golden Rules of Consent Writing
Before you write the first sentence of your form, you must understand how patients read. In a stressful medical environment, patients do not read documents word-for-word. They skim. If your form is a wall of gray text, they will skip the details and sign blindly, which invalidates the consent.
Follow these three golden rules to format your writing for readability:
#Rule 1: Target a Sixth to Eighth-Grade Reading Level
The average adult reads at an eighth-grade level, and during a medical event, stress reduces cognitive function by several grade levels. For this reason, you should write your consent documents at a sixth-grade reading level if possible.
- Use Short Sentences: Keep your sentences under fifteen words. Avoid complex clauses.
- Simplify Medical Jargon: Instead of writing "laparoscopic cholecystectomy," write "laparoscopic gallbladder removal surgery." Instead of "hemorrhage," write "severe bleeding."
- Active Voice: Write "We will clean the area" instead of "The area will be cleansed by the surgeon." Active voice is direct and easier to understand.
You can verify your document's reading difficulty by pasting your draft into our free readability checker, which measures readability scores and flags complex terms.
#Rule 2: Format for Skimming and Visual Flow
Visual layout is just as important as the words you choose. A clean, open layout helps patients find critical information quickly.
- Use Bulleted Lists: If you are listing risks, alternatives, or steps, use bullet points instead of dense paragraphs.
- Add Clear Headers: Break your form into short sections with bold, descriptive headings.
- Increase White Space: Use wide margins and line spacing. Avoid cramming text onto a single page to save paper.
- Highlight Key Words: Use bold text for critical warnings or instructions, but do not overdo it. If everything is bold, nothing stands out.
#Rule 3: Write with the "Teach-Back" Mindset
When writing, ask yourself, "Could a patient explain this section back to me in their own words?"
Do not write to impress colleagues or satisfy a lawyer's love of legalese. Write as if you are speaking directly to a patient in a quiet examination room. If a clause sounds too formal when read aloud, rewrite it using simpler language.
#2. Presentation Matters: Formatting and Skimmability
While writing your consent form in plain layman terms is necessary, visual presentation goes a very long way in achieving true patient comprehension. A wall of dense text, often called a text dump, is the worst thing you can do. When patients are faced with long, unformatted paragraphs, they get overwhelmed, stop reading, and sign blindly.
Instead of dumping text onto a page, you must design your document using layout elements that make the information skimmable and easy to follow.
#Use Structured Formatting Elements
To make your form readable, replace long paragraphs with structured layout elements:
- Tables for Comparisons: Use tables to display complex data, such as comparing the benefits and risks of different alternative treatments. Tables are easier to scan than sentences.
- Bulleted and Numbered Lists: Use bullet points to list risks or symptoms, and numbered lists to describe step-by-step procedure sequences.
- Checkbox Fields: Use optional opt-in or opt-out checkboxes for additional permissions, such as biological sample storage, audio/video recording, or research database sharing.
- Short Paragraphs: Limit your paragraphs to three or four sentences. If a paragraph is longer, break it into smaller ideas.
- Descriptive Headings: Section your form with bold, clear headers so patients can navigate directly to the information they need.
#Apply Careful Text Highlighting
Proper formatting helps draw the patient's eye to key safety warnings. However, you must use these styles selectively:
- Bold Text: Use bolding to highlight primary risk terms (such as severe bleeding or infection) or critical action verbs. Avoid bolding entire sentences.
- Italic and Underline: Use italics to emphasize patient choices or instructions, and underlines for section headings or patient declaration details.
- Text Coloring: Use subtle color changes (such as dark red) to flag high-level warnings. Never use bright, high-contrast neon colors that look unprofessional.
- Images and Infographics: As discussed in the procedure description, inserting diagrams of the affected organs or surgical cuts helps bridge the gap for visual learners.
#Skip Google Docs and Excel: Use a Dedicated Builder
Many clinics try to design their consent forms using general office tools like Microsoft Word, Google Docs, or Excel. This is a mistake. These general tools lack clinical safety guardrails, cannot verify patient reading time, and make it difficult to build structured, interactive layouts without coding.
Instead, you should use a dedicated clinical consent form builder. ConsentCollect's Free Informed Consent Builder and ConsentCollect Pro (the paid version) are highly customizable, require zero coding, and allow you to format forms that are easy to read and understand.
#Agility Matters: Deploy in Hours, Not Months
In many healthcare organizations, launching a new consent form takes two to three months because of slow coding setups, complex templates, and manual form design.
Because ConsentCollect is built to be agile, you do not spend weeks onboarding or setting up software. It takes a maximum of three to five hours to onboard your team, write a new form, and deploy it to patients. This extreme speed means you can afford to invest time in formatting your forms for maximum comprehension. Although spending time on clean visual formatting is not strictly mandated by law, it is highly encouraged to protect your practice and ensure your patients feel safe and informed.
#3. Section-by-Section Anatomy: A Gallbladder Example
To see how these rules apply in practice, we will walk through the anatomy of a standard surgical consent form. We will use a laparoscopic gallbladder removal (cholecystectomy) as our running example. This procedure is common, relatable, and its basic structure can be applied to almost any medical or surgical treatment.
| Consent Form Section | Core Purpose | Laparoscopic Cholecystectomy Example Content |
|---|---|---|
| 1. Header & Demographics | Identifies the patient, treating clinician, and facility to prevent patient-matching errors. | Patient legal name, DOB, medical ID, and primary surgeon name. |
| 2. Key Information Summary | Displays the most critical disclosures at the top of the form, per federal Common Rule requirements. | High-level summary of the diagnosis, surgery steps, top risks, and alternatives. |
| 3. Procedure Description | Describes what will happen during the treatment in plain, active language. | Explanation of the laparoscopic technique, anesthesia, and trainee participation. |
| 4. Risks & Complications | Discloses foreseeable risks, grouped clearly by frequency and severity. | Bleeding, infection, anesthesia side effects, and rare bile duct injury. |
| 5. Benefits & Alternatives | Informs the patient of the expected positive outcomes and options (including no treatment). | Pain relief benefits vs. watchful waiting, low-fat diet, or emergency infection risks. |
| 6. Autonomy & Signatures | Records voluntary agreement and details the patient's right to withdraw consent. | Voluntary declaration and distinct signature lines for patient, clinician, and witness. |
#Section 1: Header and Patient Demographics
Every form must start with a clear header. This section does not need complex writing, but it must contain accurate, searchable details:
- Patient Details: Full legal name, date of birth, and unique medical record number.
- Provider Details: The name of the primary surgeon or clinician performing the treatment.
- Encounter Details: The facility name, date of the discussion, and the specific procedure name.
💡 Pro-Tip: Do not use pre-printed stamps for patient details if you can avoid it. Stamped ink often smudges, making records unreadable during audits. If you use paper, write in clear block letters. If you use a digital builder, ensure patient info pulls automatically from your EHR.
⚠️ Common Mistake: Listing only a general clinic name instead of the specific clinician's name. The patient must know exactly who is responsible for their care.
#Section 2: The Key Information Summary
Under the federal Common Rule, consent documents must begin with a brief, focused summary of the key facts a reasonable person would want to know. This summary should be placed at the very top of the page.
Here is an example for our gallbladder removal surgery:
Key Information Summary: You are being asked to have gallbladder removal surgery because you have gallstones causing pain. The surgeon will make small cuts in your belly and use a camera to remove your gallbladder. The surgery takes about one hour. The most common risks are pain, infection, and bleeding. A rare but serious risk is injury to the bile duct, which could require another surgery to fix. You can choose not to have this surgery and manage your symptoms with dietary changes instead, though your pain may return.
💡 Pro-Tip: Keep this summary to a single paragraph of three to four sentences. Do not list every detail here. Only include the main reason for treatment, the core action, the top risks, and the primary alternative.
#Section 3: Detailed Procedure Description
This section explains the clinical details of the treatment. You must describe what will happen from start to finish, using simple terms:
- The Technique: Explain how the procedure is performed. For our example, describe laparoscopic surgery (using small cuts and a camera) and mention that the surgeon may need to switch to open surgery (a larger cut) if they find scar tissue or complications.
- Anesthesia: State that the patient will receive general anesthesia to put them to sleep.
- Trainee and Student Involvement: This is a major legal focus area. You must state clearly if medical students, residents, or other trainees will participate in the care or perform parts of the surgery.
- Visual Infographics and Diagrams: Plain text explanations can only do so much. Visual infographics go a very long way in helping patients understand where the procedure occurs, what organs are affected, and what the surgical cuts will look like. If you use a dedicated eConsent platform like ConsentCollect, adding these visuals is easy. You can fetch an infographic by URL, upload an image you already have, or use the ConsentCollect AI assistant to generate a library of procedure-specific diagrams that you can click and insert in one click.
Here is a clear way to write this description:
What will happen during the surgery: The surgeon will make three or four small cuts (each about half an inch long) in your belly. The surgical team will pump gas into your belly to inflate it, giving them room to work. The surgeon will insert a small camera and instruments through the cuts. They will detach your gallbladder and pull it out. If the surgeon finds scar tissue or bleeding during the surgery, they may need to make a larger cut (six inches) to complete the removal safely. Residents and medical students may assist under the direct supervision of your primary surgeon.
#Section 4: Material Risks and Complications
This is the most critical section for legal protection. To make it readable, group the risks by how common and how severe they are. Do not present a single list of fifty medical terms.
Here is a structured format for risk disclosure:
- Common Risks (usually mild and temporary): Pain around the cuts, shoulder soreness from the surgery gas, bruising, mild nausea from anesthesia.
- Uncommon but Serious Risks (require medical care): Wound infection, significant bleeding requiring blood transfusions, blood clots in the legs or lungs.
- Rare but Severe Risks (life-threatening): Injury to the main bile duct (occurs in less than one in two hundred cases), injury to the liver or intestines, severe allergic reactions to anesthesia.
💡 Pro-Tip: Always explain what a risk means for the patient's recovery. Do not just list "bile duct injury." Write: "Injury to the bile duct, which can leak bile into your belly and require a second operation to repair."
⚠️ Common Mistake: Omitting rare risks because you are afraid of scaring the patient. The law requires you to disclose any risk that could change a patient's mind about having the procedure.
#Section 5: Expected Benefits and Alternatives
You must explain what you expect to achieve with the treatment and what other choices are available:
- The Benefits: Focus on functional improvement. For our example, the benefit is stopping the abdominal pain and preventing gallbladder infections.
- The Alternatives: List the real options, including non-surgical management. For gallstones, alternatives include managing symptoms through low-fat dietary changes or taking medications to dissolve stones (though these are less effective).
- The No-Treatment Option: Describe what will happen if the patient decides to decline care. For example, explain that gallstones can lead to severe infections, blockages in the pancreas, or gallbladder rupture, which would require emergency surgery.
Here is how to write this section clearly:
Benefits of this surgery: The goal of this surgery is to remove the source of your pain and prevent future gallbladder attacks or serious infections.
Other options you have:
- Do nothing: You can choose to delay or decline surgery. If you do not have surgery, your gallstones will remain, and your pain may return or get worse.
- Dietary changes: You can try to manage symptoms by eating low-fat foods. This may reduce the number of painful attacks, but it will not cure the gallstones.
- Emergency risk: If you decline surgery and develop a blockage or a severe infection, you may need an emergency operation, which carries higher risks.
#Section 6: Autonomy, Revocation, and Signature Blocks
The closing of the document gathers the agreements and signatures:
- Autonomy Statement: A clear sentence confirming that the patient is making this decision voluntarily, has had their questions answered, and understands they can change their mind.
- Withdrawal Option: Explain that they can withdraw their consent at any time before the procedure begins.
- The Signature Blocks: Separate lines for the patient, the clinician obtaining consent, a witness (if required by local rules), and an interpreter (if used).
💡 Pro-Tip: Do not use signature lines that group multiple roles together. Each signer must have a distinct line, date, and timestamp.
#Review the Final Gallbladder Removal Form Template

If you choose to use modern eConsent to automate your consent collection while staying legally compliant, you can upgrade to the paid plan. We offer a free sandbox account so you can test all features (like quizzes, reading timers, and audit trail ledgers) before buying.
#4. Special Considerations for Clinical Research
If you are writing a consent form for a clinical trial or academic study rather than routine care, you must follow additional federal rules under the Common Rule (45 CFR 46) and FDA guidelines (21 CFR 50). Research consent forms are heavily audited by IRBs, and leaving out these unique clauses will delay your study start times.
| Special Research Clause | Why It Is Required | Clinical Trial Example Text |
|---|---|---|
| Randomization & Placebos | Explains the chance-based group assignment and placebo control to ensure the participant understands study design. | Explaining the coin-flip selection between study drug and placebo, and the double-blind setup. |
| Study-Related Injury Policy | Discloses whether financial compensation or free care is provided in case of adverse reactions or study injury. | Detailing who pays for emergency care and clarifying that the patient does not waive legal rights. |
| Future Use & Biobanking | Obtains explicit permission to store de-identified samples for future medical research and biobanking. | Checkbox opting in/out of de-identified sample biobanking for future genetic or medical studies. |
| Unforeseen Risks | Discloses that because the treatment is experimental, there may be side effects that are currently unknown. | Clarifying that the study drug is new and may carry side effects the researchers cannot predict yet. |
| Commercial Profits | Discloses if biological specimens may lead to commercial profits and whether the participant shares in them. | Declaring that samples may be used for commercial profit, but the participant will not receive royalties. |
Ensure your research consent form includes these five specialized sections:
#1. Explanation of Randomization and Placebos
If your study uses a randomized control trial design, you must explain how patients are assigned to treatment groups. Do not use complex statistical terms:
How we assign you to a group: We will place you into one of two groups by chance, like flipping a coin. One group will receive the study drug. The other group will receive a placebo, which looks like the study drug but contains no active medicine. Neither you nor the study doctors will know which group you are in. This is called a double-blind study.
#2. The Study-Related Injury Clause
You must explain who will pay for medical care if the participant is hurt during the study. This is a common source of legal disputes:
What happens if you are injured: If you are injured as a direct result of participating in this study, the study clinic will provide immediate medical treatment. The study sponsor will cover the reasonable costs of this emergency care. The sponsor will not provide other financial compensation, such as money for lost wages or pain. You do not waive any of your legal rights by signing this form.
#3. Future Use and Biobanking Disclosures
If you plan to store biological samples (such as blood or tissue) or genetic data for future research, you must disclose this clearly. Give participants a separate yes or no choice for future use. For more details on research sample lifecycle rules, read about consent record retention and purging:
Using your samples for future research: We would like to store your blood samples in a secure repository for future medical research. These samples will be de-identified, meaning we will remove your name and details. You can participate in the main study even if you do not want your samples stored for future research.
- YES, you may store my samples for future research.
- NO, you may not store my samples for future research.
#4. Statement of Unforeseen Risks
In clinical research, especially early-phase trials, you may not know all the side effects. You must state this uncertainty clearly:
Risks we do not know about: Because this study drug is new, there may be side effects or risks that we cannot predict. If we learn new information that might change your willingness to stay in the study, we will share it with you immediately.
#5. Commercial Profit Declarations
If your research could lead to a commercial product, you must disclose whether the participant will share in those profits:
Commercial use of specimens: Your biological samples may be used to develop new medical treatments or tests that could be sold for profit. The study sponsor and researchers may profit from these products. You will not receive any financial share or royalties from these products.
#5. Special Populations and Accessibility
A definitive writing guide must address how to manage consent for special populations. These situations are common clinical pain points that require careful documentation to satisfy federal accessibility guidelines.
#Limited English Proficiency (LEP) Patients
Under federal laws like Title VI of the Civil Rights Act, you cannot deny care or information based on a patient's native language. If a patient does not speak English fluently, you must follow these rules:
- Use Certified Medical Interpreters: Never rely on the patient's family members, especially children, to translate. They may lack medical knowledge, mistranslate risks, or pressure the patient.
- Translated Documents: If your clinic treats a significant number of patients who speak a specific language, you must translate the entire consent document.
- The Short Form Method: For rare languages where translation is not practical, you can use a written Short Form in the patient's language along with an oral explanation by an interpreter. The interpreter and a bilingual witness must sign the forms to confirm the process.
#Pediatric Assent vs. Parental Consent
Minors generally lack the legal capacity to sign a consent form. However, pediatric care and research require a two-tiered approval process:
- Parental Permission: A parent or legal guardian must sign the consent form. You must verify their relationship to the child and document their authority to make medical decisions.
- Minor Assent: For children aged seven or older, you should obtain their assent. This is a separate, simplified agreement form written at a child's reading level. The form explains what will happen using simple words and illustrations. The child signs to show they agree, even though their parent has already signed the main consent form. For more on minor assent, see our pediatric eConsent guide.
#Legally Authorized Representatives (LARs)
If an adult patient is unconscious, suffers from severe dementia, or has a mental impairment that prevents them from making decisions, you must identify a Legally Authorized Representative (LAR).
- Check the Legal Hierarchy: Follow your state or national law to identify the correct LAR. Typically, the hierarchy is: legal guardian, healthcare proxy, spouse, adult children, parents, and siblings.
- Document Authority: Scan the legal documents (such as a Durable Power of Attorney for Healthcare) and save them alongside the signed consent form in the patient's file.
- Dynamic Language and Platform Support: eConsent platforms like ConsentCollect simplify this process by allowing clinicians to switch languages dynamically on a tablet and automatically route the form to an LAR via secure email links. For virtual care details, check our telehealth eConsent guide.
#6. Traditional Print vs. Modern eConsent Workflows
Once your consent text is drafted, you must decide how to manage the signing process. You can choose between two main methods. You can use a traditional paper-based process or a modern digital workflow.
#Traditional Print-and-Sign (The Free Approach)
If your practice has low patient volume or you prefer physical documents, you can use ConsentCollect's free PDF builder.
- How it works: Use our online builder to enter your text, select your sections, and format the document. Export the draft as a clean, formatted PDF. Print the form and hand it to the patient.
- Pros: Free of cost, simple, and requires no digital devices in the clinic.
- Cons: Prone to lost paperwork, lacks readability tracking, requires physical filing or scanning, and offers weak legal protection if a patient claims they signed without understanding.
#Digital eConsent (The Paid Workflow)
For clinics looking to streamline their operations, reduce wait times, and improve legal safety, upgrading to ConsentCollect's paid digital eConsent workflow is the best path.
- How it works: The patient reviews the consent form on a tablet in the clinic or at home on their mobile device. The system guides them through the document section-by-section.
- Interactive Comprehension: You can embed short teach-back quizzes, read-aloud audio options, and mandatory reading timers. The system prevents the patient from signing until they have reviewed the material disclosures.
- Secure Audit Ledgers: ConsentCollect records a detailed audit trail. It logs IP addresses, viewport scroll duration, timestamps, and browser configurations. This trail provides a courtroom-ready forensic package.
- FHIR and EHR Integration: Once signed, the platform generates a structured HL7 FHIR R4 consent resource. The system saves this resource directly into your EHR (such as Epic or Cerner) without manual scanning.
Choosing the right approach depends on your volume, budget, and risk tolerance. For many groups, starting with free templates and upgrading to digital workflows as their volume grows is the most efficient path.
#7. Automating Compliance: The Clinical Auditor
The biggest bottleneck in writing a consent form is the review cycle. Clinical teams draft a form, send it to the compliance officer, who sends it to the legal team, who then sends it to the IRB. This process often takes weeks and involves multiple rounds of revisions because of small language errors or formatting issues.
One of the most common reasons for IRB rejection is the use of exculpatory language. Under federal rule 45 CFR 46.116, you cannot ask a patient to sign away their legal rights or release your clinic from liability for negligence.
Here are examples of illegal exculpatory language compared to compliant alternatives:
-
Prohibited: "By signing this form, you agree that you cannot sue the clinic if you are injured during the procedure."
-
Compliant: "If you are injured during this procedure, the clinic will provide emergency treatment. You do not waive any of your legal rights by signing this form."
-
Prohibited: "I release the university from any and all liability for injuries resulting from this research study."
-
Compliant: "The university does not offer financial compensation for study-related injuries, but you retain all your legal rights as a research participant."
Identifying these illegal clauses manually is difficult, especially in long documents. This is where automated compliance tools help.
ConsentCollect's Clinical Auditor acts as an automated compliance linter for your forms. You paste your draft into the builder, and the tool scans your text against hundreds of regulatory rules.
In one click, the Clinical Auditor:
- Flags Exculpatory Language: Identifies illegal waiver clauses and suggests compliant alternatives.
- Checks Readability Scores: Evaluates your reading grade level and highlights sentences that are too long or contain complex jargon.
- Verifies Required Disclosures: Checks for the eight mandatory pillars of disclosure and warns you if you missed a section (like the right to withdraw).
- Fixes Issues Instantly: Provides one-click suggestions to simplify your text and correct compliance errors, helping you avoid weeks of IRB back-and-forth reviews.
Using automated compliance tools helps you build forms that pass audits on the first attempt, saving time and keeping your projects on schedule.
