Introduction, Dysphagia—difficulty in swallowing—is a silent but serious complication in hospitalized patients, particularly those recovering from neurological, respiratory, or critical care conditions. If not recognized before discharge, it can predispose patients to aspiration pneumonia and increase the likelihood of hospital readmission. Measuring swallowing risk using validated tools may help clinicians stratify these complications early. One such instrument is the Eating Assessment Tool-10 (EAT-10), a patient-reported questionnaire that quantifies swallowing difficulty.
In this article, we review the evidence relating predischarge dysphagia assessed by EAT-10 to 90-day aspiration pneumonia and hospital readmission, discuss mechanisms, and suggest practical recommendations.

What Is the EAT-10 and Why Use It?
The EAT-10 is a simple self-administered 10-item questionnaire that asks patients to rate their swallowing-associated symptoms on a scale from 0 (no problem) to 4 (severe). A cumulative score above a threshold (commonly ≥3) suggests a risk for dysphagia.
- It is widely used in research and clinical settings because of its ease of deployment and responsiveness.
- It correlates with objective swallowing assessments and has been shown to predict aspiration risk in various populations. PubMed Central+3ResearchGate+3PubMed Central+3
- In patients hospitalized for pneumonia or neurological conditions, EAT-10 can help identify subclinical swallowing impairments before discharge. Cureus+2PubMed Central+2
Because it is non-invasive, low cost, and patient friendly, using EAT-10 just before discharge offers a practical screening step in many hospital workflows.
Association with 90-Day Aspiration Pneumonia and Readmission
Evidence from Clinical Studies
A recent study used the EAT-10 score measured just prior to discharge to evaluate whether it predicted 90-day aspiration pneumonia and hospital readmission. Cureus Their findings included:
- Patients with higher predischarge EAT-10 scores had a significantly higher incidence of developing aspiration pneumonia within 90 days post discharge.
- Higher scores were also associated with increased rates of hospital readmission (for respiratory complications or related causes) within the same period.
These results echo prior observations linking oropharyngeal dysphagia in hospitalized patients with pneumonia to worse outcomes, including recurrent respiratory infections and rehospitalizations. Cureus+3ScienceDirect+3OUP Academic+3 For example:
- Poulsen et al. showed patients with dysphagia had elevated readmission rates for both aspiration and non-aspiration pneumonia. ScienceDirect
- Cabré et al. identified oropharyngeal dysphagia as a strong predictor of hospital readmission in older adults. OUP Academic
The mechanistic rationale is that residual swallowing dysfunction (silent or overt) allows microaspiration of secretions or food particles, which may seed the lungs, especially when host defenses are weakened after hospitalization.
Risk Pathways and Contributing Factors
Several factors moderate or mediate the link between predischarge dysphagia and adverse postdischarge outcomes:
- Silent aspiration: Patients may not report overt choking or coughing, yet aspirate small volumes of saliva or secretions into the airway.
- Compromised immunity and lung defense: Hospitalized patients often have reduced physiological reserves, making them more susceptible to lower respiratory tract infection.
- Oral flora and hygiene: Poor oral hygiene can promote colonization of pathogenic bacteria, which when aspirated may cause pneumonia.
- Nutrition and functional status: Dysphagia often coexists with malnutrition and frailty, amplifying vulnerability.
- Delayed swallowing rehabilitation or feeding: If swallowing therapy or safe feeding protocols are not instituted promptly, the window to intervene is lost.
In one related study on aspiration pneumonia, delayed initiation of feeding was linked with higher readmission rates. SpringerLink
Clinical Implications & Recommendations
Given the evidence, here are key recommendations for clinicians and hospital systems:
- Implement predischarge swallowing screening
Use the EAT-10 (or similar validated tool) shortly before discharge in at-risk patients (e.g. neurological, ICU survivors, pneumonia patients). A higher score should trigger further evaluation. - Follow up with objective swallowing assessment
Patients flagged by EAT-10 should undergo more rigorous testing (e.g. video-fluoroscopy, fiberoptic endoscopic evaluation) to confirm dysphagia and aspiration risk. - Multidisciplinary swallowing rehabilitation
Speech-language pathologists, dietitians, and nursing teams should collaborate to prescribe tailored swallowing therapy, dietary modifications, and compensatory strategies. - Oral hygiene and bacterial control
Rigorous oral care protocols reduce oral pathogen load, thereby reducing the risk that aspiration introduces harmful bacteria to the lungs. - Close postdischarge monitoring & early intervention
Educate patients and caregivers to report respiratory symptoms promptly. Consider outpatient swallowing follow-up visits or home assessments. - Stratify high-risk cases
For patients with very high EAT-10 scores or known underlying risk factors (e.g. severe neurological disease), consider extended observation or transitional care plans. - Data tracking and quality improvement
Hospital systems should audit rates of aspiration pneumonia and readmission among patients with positive EAT-10, refining processes as needed.
Limitations & Research Gaps
While the association is compelling, a few caveats remain:
- Most studies are observational and cannot definitively prove causality.
- The optimal EAT-10 cutoff for risk stratification may vary by patient population.
- Some patients may revert or improve in swallowing function after discharge, complicating prediction.
- Cost-effectiveness and workflow integration of widespread EAT-10 screening remain underexplored.
Future prospective studies, randomized trials of swallowing interventions, and health economic analyses are needed.
Conclusion
Predischarge dysphagia, as quantified by the EAT-10 tool, shows a significant association with 90-day aspiration pneumonia and hospital readmission. Early identification enables targeted interventions—swallowing therapy, dietary modification, and closer follow-up—to mitigate risk. Hospitals should consider embedding EAT-10 screening into discharge planning for vulnerable patients.
By emphasizing swallowing safety before leaving the hospital, we can help reduce avoidable complications, enhance patient outcomes, and lower healthcare burden.
