Introduction
TransPlan is being developed in the open but the repository is currently private. The project will be open-sourced once it reaches a stable release milestone. Until then, access is limited to the development team and invited collaborators. If you're interested in contributing or following progress, reach out via the Contact link above.
TransPlan is a patient-facing clinical decision support tool that helps transplant patients identify the best US cities for their specific organ transplant needs.
What TransPlan Does
TransPlan analyzes 40+ data points across 8 weighted categories and scores 22 major US transplant markets. You enter your organ type, blood type, clinical scores, and urgency, and TransPlan produces a comprehensive set of outputs. These include suitability scores for each city through Phase 1 deterministic scoring, along with transplant probability estimates at 6, 12, 24, and 36 months generated by Phase 2 Monte Carlo simulation. The results also contain a competing risks breakdown showing the probability of transplant versus mortality versus delisting versus still waiting, CDF curves depicting cumulative transplant probability over time, a sensitivity analysis tornado chart revealing which inputs most affect your results, and a demographic equity analysis measuring fairness across blood types, age brackets, and sex.
Three Modes of Analysis
Phase 1: Deterministic Scoring
A rule-based weighted scoring engine that ranks cities by suitability. It is fast, transparent, and reproducible. It covers all 8 categories including policy, socioeconomic factors, and hospital quality.
Phase 2: Monte Carlo Simulation
A probabilistic engine running 1,000 simulations per city using log-normal wait time distributions parameterized from SRTR data. It outputs probability distributions with 95% confidence intervals and also models competing risks (mortality and delisting) using exponential survival models. An optional organ-specific cause-of-death (COD) multiplier adjusts donor availability by regional injury patterns.
Equity Analysis
A 48-profile demographic matrix evaluates fairness across blood types, age brackets, and sex. The Gini coefficient measures outcome equality per city, and charts visualize disparities across dimensions.
Key Features
TransPlan includes several features designed around real clinical decision-making workflows. Home Center Comparison lets you select your current listing center and see score and probability differences for each city. City Detail and Comparison allows you to click any city for a full breakdown and compare up to 3 cities side-by-side. The Organ-Specific COD Multiplier provides a toggleable adjustment for regional cause-of-death patterns affecting donor availability. Four visual themes are available (Default, Clinical, Research, and Government), and a print-friendly report view supports clinical discussions.
