Challenge brief

What you are building

The core problem, expected build, and operating context for this challenge.

Analyze synthetic cohort records across simulated medical centers to project demographic representation in clinical trial recruitment. Formulate recruitment adjustments to address severe demographic underrepresentation.

Trial Equity and Feasibility Officer

Ingest synthetic multi-center participant records with geographic and demographic covariates.

Compute site-specific eligibility yields against specified trial inclusion criteria.

Calculate disparity indices across age, sex, and ethnicity brackets against regional baselines.

Deliver a feasibility adjustment report with site-level cohort rebalancing suggestions.

Multi-site demographic breakdown dashboard with disparity index gauges and scenario simulation toggles.

Construct mock demographic records in normalized CSV or JSON format representing five simulated research hospital sites. Starter examples below are synthetic. They are not downloaded records.

HL7 FHIR overview Employ FHIR ResearchStudy and Group demographic structure patterns to define cohort stratification criteria.

anthropic-claude, pandas, scipy. anthropic-claude processes complex demographic disparity summaries to synthesize coherent site rebalancing strategies. Hosted Claude API for structured analytical summarization and protocol sensitivity review.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Ingests synthetic multi-site cohort files and validates demographic schema fields.

Computes demographic representation ratios relative to target population distributions.

Flags sites where inclusion yield drops below predetermined equity thresholds.

Outputs structured JSON containing disparity metrics and site-specific recommendations.
