UC55: Medical Knowledge Base Search

The Problem

Physicians caring for rare diseases or complex cases need rapid access to evidence-based information across multiple databases (PubMed, UpToDate, clinical practice guidelines). Manual searching is time-consuming; physicians often lack time during patient care for comprehensive literature review. A single unified search across authoritative sources accelerates evidence-informed decision-making.

What the Agent Does

Physician enters patient case summary or rare diagnosis (e.g., "45M with pemphigus vulgaris, newly diagnosed, seeking treatment guidelines")
Agent searches simultaneously across: PubMed (peer-reviewed literature), UpToDate (clinical decision support), clinical practice guidelines (ASCP, AAD, etc.), specialty society guidelines
Returns ranked results: highest-relevance publications first, tagged by evidence level (RCT, case series, expert opinion)
Provides 1 to 2 sentence summary of each result's relevance to the specific patient case
Generates curated bibliography with DOI links (for PubMed access) and direct links to guideline recommendations
Physician reviews and integrates into clinical decision
Can export bibliography for patient education or consultation letters

Data Requirements

Primary Data Sources: PubMed API, UpToDate database (subscription-based), clinical practice guideline repositories (ASCP, AAD, ACP), patient clinical summary (diagnosis, demographics, prior treatments)
Classification: PHI/PII (patient clinical summary for case-specific search)
Quality Metrics: Search relevance >90% (results align with case); publication credibility confirmed through peer review status
Complexity: Medium (multi-database search orchestration, result ranking, relevance filtering)
Systems: Epic EHR, PubMed, UpToDate

Why It Scores Well

Evidence-Based Practice: Accelerates access to current literature; improves clinical decision-making
Time Efficiency: Single search interface vs. multiple databases saves physician time
Scalability: Applies to all clinical specialty
Regulatory Fit: Decision support tool; no autonomous decisions
Implementation Simplicity: Existing database APIs; search orchestration manageable

Regulatory Alignment

HIPAA: Patient case summary is PHI; search query logs must be encrypted and audited
FDA: Literature search tool is clinical decision support; no autonomous treatment recommendations; unlikely to require premarket approval
State Medical Board: No additional requirements; tool is information aggregation
