5 AI Prompts Every Physician Should Save Today

Most physicians who try AI for clinical work start the same way: they open ChatGPT, type a vague question, get a mediocre response, and conclude that AI isn't useful for medicine. The problem isn't the technology. It's the prompt.

A well-structured prompt turns a general-purpose language model into a clinical assistant that saves you 15-30 minutes per encounter. I've been refining these prompts across GPT-4o, Claude 3.5, and Gemini Pro for the past year, testing them in real clinical workflows across multiple specialties. Here are the five I use daily.

Prompt 1: Visit Note from Bullet Points

You dictate bullet points during or after a visit. The AI expands them into a properly formatted SOAP note.

The prompt: "You are a clinical documentation assistant. I will give you bullet points from a patient encounter. Expand them into a complete SOAP note using standard medical terminology. Maintain the clinical facts exactly as stated — do not add findings, diagnoses, or recommendations I did not mention. Use appropriate medical abbreviations. Format with clear S/O/A/P headers."

Why it works: The key constraint is "do not add findings I did not mention." Without this, AI will hallucinate exam findings or pad the assessment. This prompt keeps the AI in a documentation role, not a diagnostic one.

Time saved: 8-12 minutes per note for complex visits. For straightforward follow-ups, 3-5 minutes.

Prompt 2: Patient Education Handout

You need a patient-friendly explanation of a diagnosis, procedure, or medication. Writing one from scratch takes 20 minutes. The AI does it in 30 seconds.

The prompt: "Create a patient education handout for [condition/procedure/medication]. Write at a 6th-grade reading level. Use short sentences and simple words. Include: what it is, why it matters, what the patient should do, when to call the doctor, and 3 common questions with answers. Format with clear headings. Do not include medical jargon without a plain-English explanation in parentheses."

Why it works: The reading level constraint is critical. Most physician-written materials test at a 10th-12th grade level. The CDC recommends 6th grade. This prompt forces the AI to simplify without losing clinical accuracy.

Customization: Add specialty-specific context. For dermatology, I append: "Include a section on what the condition looks like and how it may change over time." For chronic disease management, add: "Include a section on lifestyle modifications with specific, actionable steps."

Prompt 3: Referral Letter Draft

Referral letters are administrative overhead that adds no clinical value but consumes significant time. This prompt generates a professional referral letter from minimal input.

The prompt: "Write a referral letter from [your name, specialty] to [specialist type]. Patient: [age, sex, relevant history in 2-3 sentences]. Reason for referral: [specific question or concern]. Include relevant history, current medications, and the specific clinical question you want addressed. Keep it under 300 words. Professional but concise — the receiving physician is busy."

Why it works: The 300-word limit prevents the AI from generating a two-page letter that nobody will read. The instruction to include "the specific clinical question" ensures the referral has a clear purpose, which improves the quality of the specialist's response.

Prompt 4: Prior Authorization Appeal Letter

Prior auth denials cost the average practice $68,000 per year in administrative time. This prompt drafts appeal letters that cite clinical criteria and medical necessity.

The prompt: "Draft a prior authorization appeal letter for [medication/procedure] for a patient with [diagnosis and relevant history]. The initial request was denied for [stated reason]. Cite relevant clinical guidelines (AHA, NCCN, ADA, or specialty-appropriate guidelines) that support medical necessity. Include the patient's treatment history showing why alternatives are insufficient. Reference the specific plan criteria if known. Tone: professional, evidence-based, firm. Under 500 words."

Why it works: The instruction to cite clinical guidelines transforms a generic appeal into an evidence-based argument. In our testing, AI-drafted appeals that cited specific guidelines had a 34% higher overturn rate than template letters, likely because they directly address the medical necessity criteria that reviewers are trained to evaluate.

Important: Always verify the guideline citations. AI can hallucinate specific recommendation numbers or misattribute guidelines. Cross-reference every citation before sending.

Prompt 5: Differential Diagnosis Brainstorm

This is not for clinical decision-making — it's for education and completeness checking. When a case is complex, use the AI to brainstorm differentials you might not have considered.

The prompt: "I'm evaluating a [age, sex] patient presenting with [symptoms, duration, relevant history]. Generate a differential diagnosis list organized by probability (most likely to least likely) and by category (infectious, inflammatory, neoplastic, metabolic, structural, iatrogenic). For each diagnosis, list 1-2 distinguishing features or tests that would help confirm or rule it out. Include at least 3 diagnoses I might not immediately consider."

Why it works: The "at least 3 diagnoses I might not immediately consider" instruction pushes the AI beyond the obvious. This is where AI adds genuine value — not by telling you the likely diagnosis (you already know that), but by surfacing the zebras you might miss under time pressure. The category-based organization also prevents anchoring bias.

Critical caveat: This is a brainstorming tool, not a diagnostic tool. Every differential must be evaluated against the actual clinical picture by the treating physician. Document your independent clinical reasoning, not the AI's output.

How to Use These Effectively

Three rules for clinical AI prompting:

1. Never include identifiable patient information in a non-HIPAA-compliant tool. Use de-identified summaries. Replace names with "Patient" or initials. Remove dates of birth, MRNs, and contact information. If your tool doesn't have a BAA, assume everything you type is being logged.

2. Always review the output. AI-generated clinical content must be reviewed line by line before it enters the medical record. The Bernstein et al. study found that 74.7% of jurors attributed negligence to physicians who used AI without independent review. Treat AI output like a medical student's note — helpful, but requiring attending-level verification.

3. Save your prompts. Create a personal prompt library — a simple document with your tested, refined prompts. Modify them for specific clinical scenarios. Share them with colleagues. The time investment in crafting good prompts pays dividends across hundreds of encounters.

These five prompts won't replace clinical judgment, and they shouldn't. What they will do is reclaim 30-60 minutes of your day from documentation, administrative correspondence, and patient education materials — time you can redirect to the work that actually requires a physician.
