Clinical Decision Support Documents

Description

Generate professional clinical decision support (CDS) documents for pharmaceutical companies, clinical researchers, and medical decision-makers. This skill specializes in analytical, evidence-based documents that inform treatment strategies and drug development:

1. Patient Cohort Analysis - Biomarker-stratified group analyses with statistical outcome comparisons
2. Treatment Recommendation Reports - Evidence-based clinical guidelines with GRADE grading and decision algorithms

All documents are generated as publication-ready LaTeX/PDF files optimized for pharmaceutical research, regulatory submissions, and clinical guideline development.

Note: For individual patient treatment plans at the bedside, use the treatment-plans skill instead. This skill focuses on group-level analyses and evidence synthesis for pharmaceutical/research settings.

Writing Style: For publication-ready documents targeting medical journals, consult the venue-templates skill's medical_journal_styles.md for guidance on structured abstracts, evidence language, and CONSORT/STROBE compliance.

When to Use

Use this skill when you need to:

• Analyze patient cohorts stratified by biomarkers, molecular subtypes, or clinical characteristics
• Generate treatment recommendation reports with evidence grading for clinical guidelines or pharmaceutical strategies
• Compare outcomes between patient subgroups with statistical analysis (survival, response rates, hazard ratios)
• Produce pharmaceutical research documents for drug development, clinical trials, or regulatory submissions
• Develop clinical practice guidelines with GRADE evidence grading and decision algorithms
• Document biomarker-guided therapy selection at the population level (not individual patients)
• Synthesize evidence from multiple trials or real-world data sources
• Create clinical decision algorithms with flowcharts for treatment sequencing

Do NOT use this skill for:

• Individual patient treatment plans (use treatment-plans skill)
• Bedside clinical care documentation (use treatment-plans skill)
• Simple patient-specific treatment protocols (use treatment-plans skill)

Visual Enhancement with Scientific Schematics

⚠️ MANDATORY: Every clinical decision support document MUST include at least 1-2 AI-generated figures using the scientific-schematics skill.

This is not optional. Clinical decision documents require clear visual algorithms. Before finalizing any document:

1. Generate at minimum ONE schematic or diagram (e.g., clinical decision algorithm, treatment pathway, or biomarker stratification tree)
2. For cohort analyses: include patient flow diagram
3. For treatment recommendations: include decision flowchart

How to generate figures:

• Use the scientific-schematics skill to generate AI-powered publication-quality diagrams
• Simply describe your desired diagram in natural language
• Nano Banana Pro will automatically generate, review, and refine the schematic

How to generate schematics:

python scripts/generate_schematic.py "your diagram description" -o figures/output.png

The AI will automatically:

• Create publication-quality images with proper formatting
• Review and refine through multiple iterations
• Ensure accessibility (colorblind-friendly, high contrast)
• Save outputs in the figures/ directory

When to add schematics:

• Clinical decision algorithm flowcharts
• Treatment pathway diagrams
• Biomarker stratification trees
• Patient cohort flow diagrams (CONSORT-style)
• Survival curve visualizations
• Molecular mechanism diagrams
• Any complex concept that benefits from visualization

For detailed guidance on creating schematics, refer to the scientific-schematics skill documentation.

Best Practices

For Cohort Analyses

1. Patient Selection Transparency : Clearly document inclusion/exclusion criteria, patient flow, and reasons for exclusions
2. Biomarker Clarity : Specify assay methods, platforms (e.g., FoundationOne, Caris), cut-points, and validation status
3. Statistical Rigor :
   • Report hazard ratios with 95% confidence intervals, not just p-values
   • Include median follow-up time for survival analyses
   • Specify statistical tests used (log-rank, Cox regression, Fisher's exact)
   • Account for multiple comparisons when appropriate
4. Outcome Definitions : Use standard criteria:
   • Response: RECIST 1.1, iRECIST for immunotherapy
   • Adverse events: CTCAE version 5.0
   • Performance status: ECOG or Karnofsky
5. Survival Data Presentation :
   • Median OS/PFS with 95% CI
   • Landmark survival rates (6-month, 12-month, 24-month)
   • Number at risk tables below Kaplan-Meier curves
   • Censoring clearly indicated
6. Subgroup Analyses : Pre-specify subgroups; clearly label exploratory vs pre-planned analyses
7. Data Completeness : Report missing data and how it was handled

For Treatment Recommendation Reports

1. Evidence Grading Transparency :
   • Use GRADE system consistently (1A, 1B, 2A, 2B, 2C)
   • Document rationale for each grade
   • Clearly state quality of evidence (high, moderate, low, very low)
2. Comprehensive Evidence Review :
   • Include phase 3 randomized trials as primary evidence
   • Supplement with phase 2 data for emerging therapies
   • Note real-world evidence and meta-analyses
   • Cite trial names (e.g., KEYNOTE-189, CheckMate-227)
3. Biomarker-Guided Recommendations :
   • Link specific biomarkers to therapy recommendations
   • Specify testing methods and validated assays
   • Include FDA/EMA approval status for companion diagnostics
4. Clinical Actionability : Every recommendation should have clear implementation guidance
5. Decision Algorithm Clarity : TikZ flowcharts should be unambiguous with clear yes/no decision points
6. Special Populations : Address elderly, renal/hepatic impairment, pregnancy, drug interactions
7. Monitoring Guidance : Specify safety labs, imaging, and frequency
8. Update Frequency : Date recommendations and plan for periodic updates

General Best Practices

1. First Page Executive Summary (MANDATORY) :
   • ALWAYS create a complete executive summary on page 1 that spans the entire first page
   • Use 3-5 colored tcolorbox elements to highlight key findings
   • No table of contents or detailed sections on page 1
   • Use \thispagestyle{empty} and end with \newpage
   • This is the single most important page - it should be scannable in 60 seconds
2. De-identification : Remove all 18 HIPAA identifiers before document generation (Safe Harbor method)
3. Regulatory Compliance : Include confidentiality notices for proprietary pharmaceutical data
4. Publication-Ready Formatting : Use 0.5in margins, professional fonts, color-coded sections
5. Reproducibility : Document all statistical methods to enable replication
6. Conflict of Interest : Disclose pharmaceutical funding or relationships when applicable
7. Visual Hierarchy : Use colored boxes consistently (blue=data, green=biomarkers, yellow/orange=recommendations, red=warnings)
