Clinical Guidelines Search & Retrieval

Search and retrieve evidence-based clinical practice guidelines from 12+ authoritative sources spanning 41 tools. Covers disease management guidelines, society recommendations, pharmacogenomics guidance, and patient resources.

KEY PRINCIPLES:

1. Multi-source search — Search ≥3 databases in parallel for comprehensive coverage
2. Source-appropriate queries — Match query style to each database's strengths
3. Condition + society specific — When user names a disease or society, use targeted tools
4. English queries first — Use English medical terms in all tool calls; respond in user's language
5. Cite sources — Every guideline result must include source organization and URL

---

When to Use

Apply when user asks:

• "What are the guidelines for [condition]?"
• "What does [ADA/AHA/NCCN/NICE/WHO] say about [topic]?"
• "Standard of care for [disease]?"
• "Drug-gene interactions for [drug/gene]?" (pharmacogenomics)
• "Screening recommendations for [condition]?"
• "Is there a guideline for [clinical question]?"
• "What do guidelines say about [treatment/drug]?"
• "Clinical recommendations for [oncology topic]?"

---

Phase 0: Tool Verification (MANDATORY FIRST STEP)

Before searching, verify tools load:

from tooluniverse import ToolUniverse
tu = ToolUniverse()
tu.load_tools()
assert hasattr(tu.tools, 'NICE_Clinical_Guidelines_Search')

Correct call pattern (use either approach):

# Option A: direct attribute access
result = tu.tools.NICE_Clinical_Guidelines_Search(query='diabetes', limit=5)

# Option B: run_one_function
result = tu.run_one_function({'name': 'NICE_Clinical_Guidelines_Search', 'arguments': {'query': 'diabetes', 'limit': 5}})

NCI Resources ⚠️ (Research tools catalog, NOT clinical guidelines)

NCI_search_cancer_resources(q, size) — Search NCI Research Resources for Researchers (R4R).

• ⚠️ This is a catalog of bioinformatics tools, datasets, and lab instruments — NOT a clinical guidelines database
• Parameters: q (NOT query), size (NOT limit — use size for result count)
• Returns: dict — r.get('data', {}).get('results', []) gives the list
• Useful for: finding analysis tools, datasets, bioinformatics resources related to a cancer type
• Example: NCI_search_cancer_resources(q='colorectal cancer screening', size=5)

2.3 Pharmacogenomics Search (CPIC)

Recommended workflow for gene-drug queries:

Step 1: CPIC_get_gene_info(genesymbol='GENE')          → gene overview
Step 2: CPIC_get_gene_drug_pairs(genesymbol='GENE')    → all drug pairs + CPIC levels
Step 3: CPIC_list_guidelines(limit=50)                 → find guideline_id for gene+drug
Step 4: CPIC_get_recommendations(guideline_id=N)       → specific dosing recommendations
Step 5: CPIC_get_alleles(genesymbol='GENE')            → allele definitions

All CPIC tools return dict-wrapped: use r.get('data', []) to access results.

CPIC_get_gene_info(genesymbol) — Gene overview.

• Example: CPIC_get_gene_info(genesymbol='CYP2D6')

CPIC_get_gene_drug_pairs(genesymbol, limit) — All gene-drug interactions with CPIC levels.

• Returns: data = list of {genesymbol, drugid, cpiclevel, pgkbcalevel, usedforrecommendation, ...}
• cpiclevel A/B/C/D: A = strongest evidence

CPIC_list_guidelines(limit) — All CPIC guidelines.

• Returns: data = list of {name: 'GENE and Drug', guidelineId, url, ...}
• Use to find the guidelineId for a specific gene+drug pair

CPIC_get_recommendations(guideline_id, limit) — Get dosing recommendations.

• ⚠️ Parameter is guideline_id (integer), NOT genesymbol
• Workflow: first find guideline_id from CPIC_list_guidelines, then call this
• Example: CPIC_get_recommendations(guideline_id=100416, limit=20)
• Returns duplicate records per allele combination — deduplicate by phenotype before presenting

CPIC_get_alleles(genesymbol, limit) — Allele definitions.

• Use clinicalfunctionalstatus field (NOT functionalstatus which is always null)
• Example: CPIC_get_alleles(genesymbol='CYP2D6', limit=10)

CPIC_get_drug_info(drugname) — Drug details.

• Example: CPIC_get_drug_info(drugname='codeine')

CPIC_search_gene_drug_pairs(genesymbol, limit) — Search gene-drug pairs.

• ⚠️ Requires PostgREST filter syntax: genesymbol='eq.CYP2D6' (not just 'CYP2D6')
• Example: CPIC_search_gene_drug_pairs(genesymbol='eq.CYP2D6', limit=5)

2.4 Full-Text Retrieval

NICE_Guideline_Full_Text(url) — Get NICE guideline text.

• Use URL from NICE_Clinical_Guidelines_Search results
• Returns dict (may have empty data for some guidelines; try chapter URLs like .../chapter/Recommendations)

WHO_Guideline_Full_Text(url) — Get WHO guideline text.

Phase 3: Synthesize Results

3.1 Report Structure

# Clinical Guidelines: [Topic]

## Summary
[2-3 sentence overview of what guidelines say]

## Key Recommendations

### [Source 1: NICE/ADA/NCCN/etc.]
[Key recommendations with evidence grade, URL]

### [Source 2]
[Key recommendations]

## Pharmacogenomics (if applicable)
[CPIC phenotype-to-recommendation table]

## References
[All URLs cited]

3.2 Evidence Grading

• Grade A (ADA) / Class I (AHA) / Strong (SIGN) = high confidence
• Grade B/C = moderate confidence; Grade D / Consensus = expert opinion
• CPIC Level A = strongest PGx evidence; B = moderate; C/D = limited
• Note recommendation year — guidelines vary in currency (SIGN 2025, ADA 2026, NICE Feb 2026)

3.3 CPIC Recommendation Deduplication

CPIC returns multiple records for the same phenotype (one per allele combination). Before presenting:

seen_phenotypes = set()
unique_recs = []
for rec in recs:
    phenotype = rec.get('phenotype') or rec.get('lookupkey', '')
    if phenotype not in seen_phenotypes:
        seen_phenotypes.add(phenotype)
        unique_recs.append(rec)

Phase 4: Decision Logic

General disease guideline:

1. NICE (query, limit) — UK, high quality
2. GIN (query, limit) — multi-society aggregator ⭐ best for breadth
3. TRIP (query, limit, search_type='guidelines')
4. If cardiac → add AHA_ACC_search_guidelines
5. If cancer → add NCCN_search_guidelines + NCCN_list_patient_guidelines
6. If diabetes → add ADA_list_standards_sections + ADA_search_standards

Pharmacogenomics:

1. CPIC_get_gene_info(genesymbol) → overview
2. CPIC_get_gene_drug_pairs(genesymbol) → all drugs with CPIC levels
3. CPIC_list_guidelines(limit=50) → find guideline_id for target gene+drug
4. CPIC_get_recommendations(guideline_id=N) → specific recs (deduplicate by phenotype)

Full text retrieval:

1. Find guideline URL/PMID from search results
2. NICE URL → NICE_Guideline_Full_Text
3. AHA/ACC PMID → AHA_ACC_get_guideline
4. WHO URL → WHO_Guideline_Full_Text
5. NCCN patient guideline URL → NCCN_get_patient_guideline

Fallback strategy:

• If NICE returns empty → try TRIP or GIN
• If ADA returns 0 results → broaden query terms (e.g., 'pharmacologic approaches' instead of 'metformin first-line')
• If WHO returns irrelevant results → skip WHO, use GIN or EuropePMC instead
• If CPIC returns no recommendations → list gene-drug pairs with CPIC levels as a proxy

Known Limitations

• WHO_Guidelines_Search: Returns recently-published WHO docs regardless of query topic — results may be irrelevant for specific diseases. Supplement with GIN for international guidelines.
• NCI_search_cancer_resources: Catalogs research tools/datasets, NOT clinical practice guidelines.
• NICE_Guideline_Full_Text: Retrieves overview page only; recommendation sub-pages (.../chapter/Recommendations) may need direct URL
• SIGN: No full-text tool; guideline text only available as PDFs
• ADA_get_standards_section: Returns abstract only, not full PMC text
• CPIC_get_recommendations: Returns many duplicate records per allele combination; deduplicate by phenotype
• NCCN_search_guidelines: Returns PubMed/JNCCN abstracts, not proprietary NCCN guideline text
• TRIP content: Some TRIP results link to PDF-gated URLs; content extraction may fail with 403

Missing Sources (Potential Future Tools)

• USPSTF (US Preventive Services Task Force) — primary US screening recommendations
• ACG (American College of Gastroenterology) — gastroenterology guidelines
• AGA (American Gastroenterological Association)
• Cochrane Reviews — systematic reviews on clinical interventions
• AHRQ — Agency for Healthcare Research and Quality
