In this single-center retrospective cohort of 197 geriatric patients who underwent fixation of OTA/AO 31-A/B/C hip fractures, an AI-driven Clinical Deterioration Index (CDI, 0–100 from 31 clinical measures) measured in the first 48 postoperative hours identified 15 patients (7.6%) with CDI ≥65 who had more complications (93.3% vs 26.4%), longer stays (10.1 vs 5.2 days), shorter discharge ambulation (8.8 vs 42.3 feet), and higher one-year mortality (20.0% vs 3.8%), while the institutional cutoff of 65 showed high specificity (99.3%) but low sensitivity (22.6%) and an optimized threshold of 47.7 raised sensitivity to 77.4% with comparable accuracy (75.0%).
