Abstract

Purpose

This study aims to explore the prevalence of dysphagia, as well as mortality associated with dysphagia in the elderly population receiving surgical treatment for a hip fracture.

Methods

A retrospective cohort study was completed at an academic level 1 tertiary care center. Patients older than or equal to 65 admitted with a hip fracture diagnosis from January 2015 to December 2020 (n = 617) were included. The main outcome was the prevalence of dysphagia and association with mortality. Secondary analysis included timing of dysphagia and contributions to mortality.

Results

Fifty-six percent of patients had dysphagia, and the mortality rates were higher in patients with dysphagia (8.9%) versus those without dysphagia (2.6%), chi-square p = 0.001, and odds ratio 3.69 (CI 1.6–8.5). Mortality rates in patients with acute dysphagia were also higher (12.4%) than those with chronic dysphagia (5%) and chi-squared p = 0.02. Mortality rates in patients with a perioperative dysphagic event (13.9%) were higher than those with non-perioperative dysphagia (4%) and chi-squared p = 0.001. Mortality rates in patients who had acute perioperative dysphagia (21.2%) were higher than those with chronic dysphagia that presented perioperatively (6.8%) and chi-squared p = 0.006.

Conclusions

This study demonstrates high rates of dysphagia in the elderly hip fracture population and a significant association between dysphagia and mortality. Timing and chronicity of dysphagia were relevant, as patients with acute perioperative dysphagia had the highest mortality rate. Unlike other identified risk factors, dysphagia may be at least partially modifiable. More research is needed to determine whether formal evaluation and treatment of dysphagia lowers mortality risk.
