H&P Documentation Guide

The H&P as a Clinical Reasoning Document

The History and Physical (H&P) is the most comprehensive note a physician writes. It captures a complete clinical snapshot of the patient at the time of admission or initial consultation. But it is more than a data repository — it is a clinical reasoning document. A well-written H&P walks the reader through your diagnostic thinking: what information you gathered, how you interpreted it, and what you plan to do about it. The H&P sets the stage for subsequent documentation like the discharge summary.

This guide covers the practical skills needed to write an H&P that is thorough, efficient, and genuinely useful. Whether you are a medical student writing your first admission note or an attending refining your documentation, these principles apply.

Building a Strong HPI

The History of Present Illness is the most important section of the H&P. It is the clinical narrative — the story of how the patient arrived in front of you. A strong HPI should be readable as a standalone paragraph that conveys the clinical picture clearly enough for another physician to start forming a differential diagnosis. Good HPI writing follows principles outlined in clinical narrative documentation.

The Opening Line

Your HPI should begin with a one-sentence patient identifier that establishes context immediately.

Formula: [Age]-year-old [sex] with a history of [relevant PMH] presenting with [chief complaint] for [duration].

• Example: "72-year-old female with a history of hypertension, type 2 diabetes, and prior stroke presenting with acute onset left-sided weakness for three hours."
• Example: "34-year-old previously healthy male presenting with five days of progressive dyspnea and productive cough."

What to include in the opening line: Only past medical history that is directly relevant to the current presentation. A patient admitted for pneumonia needs their COPD and immunosuppression mentioned upfront — not their distant cholecystectomy.

Chronological Narrative

After the opening line, develop the story chronologically. The reader should be able to follow the symptom from onset to the present moment.

Structure the narrative around these elements:

1. When and how it started. "Three hours ago, while eating dinner, the patient noticed that her left hand became clumsy and she could not grip her fork."
2. How it evolved. "Over the next 30 minutes, weakness progressed to involve the entire left arm and leg. She developed a leftward facial droop."
3. What the patient did. "Her husband called 911. She was transported by EMS to our ED."
4. What has been found so far. "In the ED, NIHSS score was 12. CT head was negative for hemorrhage. CTA showed right MCA occlusion."
5. Current status. "She is now 2.5 hours from symptom onset and within the window for IV thrombolysis."

Pertinent Positives and Negatives

Throughout the HPI, weave in the pertinent positives (symptoms present that support your differential) and pertinent negatives (symptoms absent that help exclude alternatives).

Example for the stroke case:

• Pertinent positives: Acute onset, focal weakness (left arm and leg), facial droop, history of hypertension and diabetes (vascular risk factors)
• Pertinent negatives: "Denies headache, nausea, vomiting, seizure, recent trauma, or fever. No anticoagulant use. No recent surgery."

The pertinent negatives tell the reader what you considered and actively ruled out during history-taking. They demonstrate clinical reasoning within the HPI itself.

Common HPI Mistakes

Mistake 1: The data dump. Listing every symptom and lab value without narrative structure. The HPI should read like a story, not a spreadsheet.

Mistake 2: Starting too far back. "Patient has had diabetes since 2004 and hypertension since 2010..." This is PMH, not HPI. Start the HPI at the onset of the acute problem.

Mistake 3: Omitting the timeline. "Patient has been having chest pain." When did it start? Is it getting worse? Has it happened before? Temporal information is essential.

Mistake 4: Including unnecessary detail. "Patient ate chicken for dinner before the event" is irrelevant to a stroke presentation. Filter for clinical relevance.

Documenting the Review of Systems

The Review of Systems (ROS) is a systematic inquiry beyond the HPI that screens for symptoms the patient may not have volunteered. For a comprehensive H&P, document at least 10 organ systems.

Efficient ROS documentation

The ROS does not need to be a long list of negatives. Focus your documentation:

1. Start with pertinent systems. For a chest pain admission, the cardiovascular, respiratory, and GI systems deserve detailed documentation. A full musculoskeletal ROS is less relevant.
2. Document pertinent positives in detail. "Positive for exertional dyspnea — onset 2 weeks ago, associated with chest tightness, limiting walking to half a block" is useful.
3. Batch the negatives. "Remaining systems reviewed and negative" is acceptable for systems not pertinent to the presentation, though some billing requirements demand explicit documentation of each system.

The ROS vs. HPI boundary

A common question: if a symptom was already discussed in the HPI, does it need to appear again in the ROS? The standard practice is to note "see HPI" for systems already covered in detail. Double-documenting the same information wastes time and space.

The Physical Exam: Document What You Actually Found

The physical exam section should reflect what you personally observed, not what a template auto-populated.

Principles for exam documentation

Document real findings, not templates. "Heart: RRR, no m/r/g" is acceptable shorthand, but only if you actually auscultated the heart. An auto-populated normal exam for a system you did not examine is fraudulent documentation.

Be specific about abnormal findings. Not "murmur noted" but "Grade 3/6 systolic crescendo-decrescendo murmur best heard at the right upper sternal border, radiating to the carotids, diminished with Valsalva." Specific findings drive accurate diagnosis and allow subsequent examiners to track changes.

Use quantitative language when possible.

• "2+ pitting edema to the mid-shins bilaterally" rather than "some leg swelling"
• "5 cm area of erythema and induration over the left medial malleolus" rather than "skin infection on the leg"
• "Strength 3/5 in left upper and lower extremities" rather than "left-sided weakness"

Document the pertinent negatives of the exam. For a patient with suspected appendicitis, documenting "no Rovsing sign, no psoas sign, no obturator sign" shows you performed a thorough evaluation — not just that you pushed on the right lower quadrant.

Vital Signs: Do Not Skip the Context

Record all vital signs, but add context when the numbers are clinically significant.

• "BP 188/102 mmHg (right arm, manual cuff) — patient is in pain and received no antihypertensives in the ED"
• "HR 112, regular — likely sinus tachycardia in the setting of fever and dehydration"
• "SpO2 88% on room air, improving to 95% on 3 L NC"

Writing the Assessment: Show Your Thinking

The Assessment is where you earn your keep as a physician. This section synthesizes the data into a clinical impression and demonstrates your diagnostic reasoning.

The Synthesis Statement

Begin with a one-sentence summary that orients the reader.

Example: "Mr. Park is a 45-year-old previously healthy male presenting with thunderclap headache maximal at onset, raising concern for subarachnoid hemorrhage despite a negative CT head."

The Problem List With Reasoning

For each active problem, provide:

1. The diagnosis or differential — what you think it is, ranked by likelihood
2. The evidence — what supports each diagnosis
3. The counter-evidence — what argues against alternatives
4. The plan — what you will do to confirm, treat, or monitor

Example:

"Problem 1: Thunderclap headache — rule out SAH Clinical presentation — sudden onset, maximal severity within seconds, occipital location, associated vomiting — is classic for SAH. Risk factors include hypertension (intermittent per patient) and exertional onset. CT head is negative, but sensitivity decreases to approximately 93% after 6 hours, and the patient presented at 7 hours from onset. LP is indicated to evaluate for xanthochromia.

Differential also includes RCVS (possible given exertional trigger, but typically recurrent thunderclap headaches over days — this is a first episode) and primary thunderclap headache (diagnosis of exclusion after SAH and RCVS are ruled out)."

Common Assessment Mistakes

Mistake 1: Diagnosis list without reasoning. Writing "1. Pneumonia, 2. CHF, 3. Diabetes" without explaining why you think the patient has each condition or how the conditions interact tells the reader nothing about your clinical thinking.

Mistake 2: Anchoring. Committing to a single diagnosis without acknowledging the differential. If you are wrong, a subsequent reviewer will wonder why alternatives were not considered.

Mistake 3: Ignoring uncertainty. Medicine is uncertain. It is better to document "Differential includes X, Y, and Z; pursuing workup to differentiate" than to assert a premature diagnosis.

Writing the Plan: Make It Actionable

The Plan translates your Assessment into orders. Each problem in the Assessment should have a corresponding set of action items in the Plan.

Plan components for each problem

• Diagnostics: Labs, imaging, consultations to be ordered
• Therapeutics: Medications (with doses), procedures, interventions
• Monitoring: What to watch and how often (serial exams, repeat labs, telemetry)
• Patient education: What was discussed with the patient
• Contingency: What triggers escalation (e.g., "if troponin trends up, call cardiology for possible catheterization")
• Disposition: Expected level of care, anticipated length of stay

Examples of strong vs. weak plan items

Efficiency Strategies for H&P Writing

1. Use a Consistent Structure

Write every H&P in the same order. Your brain will develop a rhythm, and you will stop wondering what comes next. The standard structure — CC, HPI, ROS, PMH/PSH/FH/SH, Meds, Allergies, Exam, Data, Assessment, Plan — exists because it works.

2. Dictate the HPI

The HPI is the most time-consuming section to type and the most natural to speak. Dictate it as a narrative while the patient's story is fresh in your mind. Then type or template the structured sections (ROS, PMH, meds).

3. Front-Load the Assessment

Many physicians write the H&P top-down: CC first, then HPI, then ROS, and finally get to the Assessment at the end. Try writing the Assessment and Plan first while your clinical reasoning is sharpest, then fill in the supporting sections.

4. Do Not Over-Document

A comprehensive H&P does not mean an exhaustive H&P. Document what is clinically relevant. A 14-system ROS and 12-system physical exam for a straightforward cellulitis admission is unnecessary and wastes your time.

5. Review Before Signing

Read your note once before signing it. Check that the Assessment references findings from the HPI and Exam, that the Plan addresses every problem in the Assessment, and that there are no copy-forward artifacts if you used a prior note as a starting point.

Automate Your H&P Documentation

The admission H&P is often written at the end of a long call day when cognitive fatigue is highest and documentation accuracy is lowest. NotuDocs generates comprehensive H&P notes from your recorded patient encounters, structuring the HPI, exam, assessment, and plan — so you review and refine a draft instead of writing the entire document from memory.
