Background: This study investigates the association between the Geriatric Nutritional Risk Index (GNRI), a simple, readily available malnutrition risk index, and 30-day postoperative complications following shoulder arthroscopy. Methods: The American College of Surgeons National Surgical Quality Improvement Program database was used to identify all patients aged ≥65 years who underwent shoulder arthroscopy between 2015 and 2021. The study population was indexed into 3 cohorts of preoperative GNRI: normal/reference (GNRI >98), moderate malnutrition (92≤ GNRI ≤98), and severe malnutrition (GNRI 2 days (OR: 23.66, 95% CI: 16.25-34.45; P < .001), and mortality (OR: 14.25, 95% CI: 2.89-70.40; P = .001). Conclusion: GNRI-based malnutrition is strongly predictive of perioperative complications following shoulder arthroscopy in geriatric patients and has utility as an adjunctive risk stratification tool.
