# Clinical Report Writing

## Overview

Clinical report writing is the process of documenting medical information with precision, accuracy, and compliance with regulatory standards. This skill covers four major categories of clinical reports: case reports for journal publication, diagnostic reports for clinical practice, clinical trial reports for regulatory submission, and patient documentation for medical records. Apply this skill for healthcare documentation, research dissemination, and regulatory compliance.

**Critical Principle: Clinical reports must be accurate, complete, objective, and compliant with applicable regulations (HIPAA, FDA, ICH-GCP).** Patient privacy and data integrity are paramount. All clinical documentation must support evidence-based decision-making and meet professional standards.

## When to Use This Skill

This skill should be used when:
- Writing clinical case reports for journal submission (CARE guidelines)
- Creating diagnostic reports (radiology, pathology, laboratory)
- Documenting clinical trial data and adverse events
- Preparing clinical study reports (CSR) for regulatory submission
- Writing patient progress notes, SOAP notes, and clinical summaries
- Drafting discharge summaries, H&P documents, or consultation notes
- Ensuring HIPAA compliance and proper de-identification
- Validating clinical documentation for completeness and accuracy
- Preparing serious adverse event (SAE) reports
- Creating data safety monitoring board (DSMB) reports

## Core Capabilities

### 1. Clinical Case Reports for Journal Publication

Clinical case reports describe unusual clinical presentations, novel diagnoses, or rare complications. They contribute to medical knowledge and are published in peer-reviewed journals.

#### CARE Guidelines Compliance

The CARE (CAse REport) guidelines provide a standardized framework for case report writing. All case reports should follow this checklist:

**Title**
- Include the words "case report" or "case study"
- Indicate the area of focus
- Example: "Unusual Presentation of Acute Myocardial Infarction in a Young Patient: A Case Report"

**Keywords**
- 2-5 keywords for indexing and searchability
- Use MeSH (Medical Subject Headings) terms when possible

**Abstract** (structured or unstructured, 150-250 words)
- Introduction: What is unique or novel about the case?
- Patient concerns: Primary symptoms and key medical history
- Diagnoses: Primary and secondary diagnoses
- Interventions: Key treatments and procedures
- Outcomes: Clinical outcome and follow-up
- Conclusions: Main takeaway or clinical lesson

**Introduction**
- Brief background on the medical condition
- Why this case is novel or important
- Literature review of similar cases (brief)
- What makes this case worth reporting

**Patient Information**
- Demographics (age, sex, race/ethnicity if relevant)
- Medical history, family history, social history
- Relevant comorbidities
- **De-identification**: Remove or alter 18 HIPAA identifiers
- **Patient consent**: Document informed consent for publication

**Clinical Findings**
- Chief complaint and presenting symptoms
- Physical examination findings
- Timeline of symptoms (consider timeline figure or table)
- Relevant clinical observations

**Timeline**
- Chronological summary of key events
- Dates of symptoms, diagnosis, interventions, outcomes
- Can be presented as a table or figure
- Example format:
  - Day 0: Initial presentation with symptoms X, Y, Z
  - Day 2: Diagnostic test A performed, revealed finding B
  - Day 5: Treatment initiated with drug C
  - Day 14: Clinical improvement noted
  - Month 3: Follow-up examination shows complete resolution

**Diagnostic Assessment**
- Diagnostic tests performed (labs, imaging, procedures)
- Results and interpretation
- Differential diagnosis considered
- Rationale for final diagnosis
- Challenges in diagnosis

**Therapeutic Interventions**
- Medications (names, dosages, routes, duration)
- Procedures or surgeries performed
- Non-pharmacological interventions
- Reasoning for treatment choices
- Alternative treatments considered

**Follow-up and Outcomes**
- Clinical outcome (resolution, improvement, unchanged, worsened)
- Follow-up duration and frequency
- Long-term outcomes if available
- Patient-reported outcomes
- Adherence to treatment

**Discussion**
- Strengths and novelty of the case
- How this case compares to existing literature
- Limitations of the case report
- Potential mechanisms or explanations
- Clinical implications and lessons learned
- Unanswered questions or areas for future research

**Patient Perspective** (optional but encouraged)
- Patient's experience and viewpoint
- Impact on quality of life
- Patient-reported outcomes
- Quote from patient if appropriate

**Informed Consent**
- Statement documenting patient consent for publication
- If patient deceased or unable to consent, describe proxy consent
- For pediatric cases, parental/guardian consent
- Example: "Written informed consent was obtained from the patient for publication of this case report and accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal."

For detailed CARE guidelines, refer to `references/case_report_guidelines.md`.

#### Journal-Specific Requirements

Different journals have specific formatting requirements:
- Word count limits (typically 1500-3000 words)
- Number of figures/tables allowed
- Reference style (AMA, Vancouver, APA)
- Structured vs. unstructured abstract
- Supplementary materials policies

Check journal instructions for authors before submission.

#### De-identification and Privacy

**18 HIPAA Identifiers to Remove or Alter:**
1. Names
2. Geographic subdivisions smaller than state
3. Dates (except year)
4. Telephone numbers
5. Fax numbers
6. Email addresses
7. Social Security numbers
8. Medical record numbers
9. Health plan beneficiary numbers
10. Account numbers

13. Device identifiers and serial numbers
14. Web URLs
15. IP addresses
16. Biometric identifiers
17. Full-face photographs
18. Any other unique identifying characteristic

**Best Practices:**
- Use "the patient" instead of names
- Report age ranges (e.g., "a woman in her 60s") or exact age if relevant
- Use approximate dates or time intervals (e.g., "3 months prior")
- Remove institution names unless necessary
- Blur or crop identifying features in images
- Obtain explicit consent for any potentially identifying information

### 2. Clinical Diagnostic Reports

Diagnostic reports communicate findings from imaging studies, pathological examinations, and laboratory tests. They must be clear, accurate, and actionable.

- Example:
  - "1. Bilateral ground-glass opacities consistent with viral pneumonia or atypical infection. COVID-19 cannot be excluded. Clinical correlation recommended.
  - 2. No evidence of pulmonary embolism.
  - 3. Recommend follow-up imaging in 4-6 weeks to assess resolution."

**Structured Reporting:**

Many radiology departments use structured reporting templates for common examinations:
- Lung nodule reporting (Lung-RADS)
- Breast imaging (BI-RADS)
- Liver imaging (LI-RADS)
- Prostate imaging (PI-RADS)
- CT colonography (C-RADS)

Structured reports improve consistency, reduce ambiguity, and facilitate data extraction.

## Common Pitfalls to Avoid

### Case Reports
- **Privacy violations**: Inadequate de-identification or missing consent
- **Lack of novelty**: Reporting common or well-documented cases
- **Insufficient detail**: Missing key clinical information
- **Poor literature review**: Failure to contextualize within existing knowledge
- **Overgeneralization**: Drawing broad conclusions from single case

### Diagnostic Reports
- **Vague language**: Using ambiguous terms like "unremarkable" without specifics
- **Incomplete comparison**: Not reviewing prior imaging
- **Missing clinical correlation**: Failing to answer clinical question
- **Technical jargon**: Overuse of terminology without explanation
- **Delayed critical value notification**: Not communicating urgent findings

### Clinical Trial Reports
- **Late reporting**: Missing regulatory deadlines for SAE reporting
- **Incomplete causality**: Inadequate causality assessment
- **Data inconsistencies**: Discrepancies between data sources
- **Protocol deviations**: Unreported or inadequately documented deviations
- **Selective reporting**: Omitting negative or unfavorable results

### Patient Documentation
- **Illegibility**: Poor handwriting in paper records
- **Copy-forward errors**: Propagating outdated information
- **Insufficient detail**: Vague or incomplete documentation affecting billing
- **Lack of medical necessity**: Not documenting indication for services
- **Missing signatures**: Unsigned or undated notes
