Idea
Model predicting physician referral links to optimize care coordination and reduce healthcare fragmentation.
Research Paper
Core Innovation
This paper introduces H3, a three-hop index that models indirect referral pathways with degree-based normalization and redundancy penalties to reduce hub-mediated noise. Unlike prior methods, H3 captures intrinsic network properties such as sparsity and disassortative mixing, delivering transparent and decomposable predictions that outperform classical heuristics and deep learning baselines.
Why It Matters
Accurate physician referral prediction reduces care fragmentation and improves coordination, leading to better patient outcomes and system efficiency. By addressing network sparsity and hub noise, H3 enhances prediction reliability and transparency, facilitating adoption by healthcare providers and payers. This scalable approach supports evolving referral patterns over time, critical for dynamic healthcare environments.
Market Size (TAM)
$10–20B TAM for healthcare network analytics; $2–5B SAM from hospitals, insurers, and health IT vendors. Driven by increasing demand for care coordination and network optimization.
