| Summary: | Objective: Femoral nerve blocks (FNBs) for fragility hip fractures have benefits in improving pain relief and early mobilization while decreasing opioid use and rates of pneumonia. However, no study has looked at 1-year mortality outcomes for this intervention. This study aims to provide insight into 1-year outcomes. Methods: A single-site retrospective case–control study from 2007 to 2016 in primary fragility hip fractures compared 665 patients who received an emergency department FNB to 326 patients who did not receive an FNB. The primary outcome was 1-year mortality. Secondary outcomes included mortality, mobility, and residence at discharge, 6 months, and 1-year intervals. Results: There were no significant differences in preoperative characteristics. Although there was no statistically significant difference in 1-year mortality, patients who did not receive an FNB were more likely to be nonambulant at 1 year (odds ratio 1.71, 95% confidence interval, 1.14-2.57, P = .005). There were no other significant differences in mobility, residence, or mortality. Conclusion: There was no statistically significant difference in 1-year mortality, although individuals who did not receive an FNB were more likely to be nonambulant at 1 year.
