A complex network of glowing red and blue lines connects nodes, with spheres labeled 2016, 2019, and 2022. Various data charts and titles like "Semantic Drift" and "Clinical Transition Drift" are overlaid, with a blurry cityscape and figures of medical professionals below. Cinematic style.

Micro-Level Drift (NRD: Cardiac Diagnosis Codes) Using cardiac ICD diagnosis and procedure codes, the framework models patient transition dynamics and readmission behavior. Key drift dimensions include: Semantic Drift: Changes in coding patterns, comorbidity representation, and diagnostic granularity over time. Clinical Transition Drift: Variation in readmission pathways, state persistence, and transition entropy. Risk Distribution Drift: Shifts in severity mix and demographic composition affecting predicted readmission probabilities. Metrics: transition entropy, sparsity, risk-threshold shifts, and trajectory divergence. Macro-Level Drift (CMS HRRP) The HRRP dataset captures hospital-level readmission penalties and performance classifications. Economic Drift: Changes in penalty structures and financial incentives. Operational Drift: LOS changes, staffing effects, institutional throughput adjustments. Structural Drift: Hospital class transitions and reconfiguration patterns. Decision Drift: Institutional responses to penalty thresholds. Metrics: class Mehr sehen
