  "abstract": "Rural and socially deprived areas often face limited access to healthcare services and professionals, leading to suboptimal care and poorer outcomes. The AIPAD project develops a scalable, data‑driven framework to quantify inequalities in peripheral artery disease (PAD) and build ML models that account for and reduce these biases, ultimately supporting surgeons and promoting more equitable care. We conducted an observational, longitudinal study using data from the French National Health Insurance Information System. All adult patients who underwent lower‑limb revascularisation between January 2016 and December 2024 were included. Socio‑demographic, medical, and intra‑operative variables were used to predict major adverse limb events (MALE) or one‑year all‑cause mortality. Logistic regression, random forest, and XGBoost models were evaluated using performance metrics (AUC, accuracy) and fairness measures, focusing on True Positive Rate Balance (TPRB) across FDEP‑defined socio‑economic groups. A total of 702,016 patients were analysed. Among them, 14.7% belonged to the first and least deprived FDEP quintile, while 22.8% were classified in FDEP quintile 5 (most deprived). The best-performing model was a XGBoost algorithm incorporating medical and intra‑operative variables (AUC=0.779). However, across FDEP quintiles 1 to 5, the AUC decreased from 0.787 to 0.774, and accuracy decreased from 0.714 to 0.694, indicating a socio‑economic gradient in model performance. The TPRB was −0.02, reflecting lower sensitivity in the most deprived group. These findings highlight the need for equity‑oriented strategies. In this workshop, we propose to present our results and illustrate the importance of sampling approaches to reduce performance gaps while preserving global accuracy. Overall, we will demonstrate that integrating social and territorial dimensions into ML models is essential to improve risk prediction while avoiding reinforcement of existing healthcare inequalities.",
