Background: The neutrophil-to-lymphocyte ratio (NLR) is an inflammatory biomarker. Objective: To evaluate if levels were associated with the development of delirium in older adults hospitalized for hip fracture. Methods: An observational, prospective, analytical pilot study was conducted. Forty participants ≥ 65 years old hospitalized for hip fractures were included. NLR levels were collected from the medical records during the first 24 h of admission of each patient and every 72 h. Results: Twelve participants had delirium. There was no significant difference in the NLR median value at admission in the delirium group versus the no-delirium group (p = 0.768). We found a significant age difference (p = 0.02), cognition (p = 0.004), and activities of daily living (p = 0.004) between groups. In univariate analysis, age ≥ 80 (odds ratio [OR]: 4.22; 95% confidence interval [CI]: 1.0-17.79; p = 0.05), cognitive impairment (OR: 27.0; 95% CI: 2.72-267.79; p = 0.005), and a Lawton and Brody test < 3 score (OR: 13.8; 95% CI: 2.71-7.12; p = 0.002) were associated with an increased risk of delirium. Conclusion: The association between the NLR value and the development of delirium was not observed, but advanced age, moderate/severe cognitive impairment, and decreased instrumental activities of daily living performance were associated with a higher risk of delirium in older adults hospitalized for hip fracture with an increased risk of delirium.
