Management of Dysphagia

Critical First Steps: Determine Dysphagia Type and Risk Stratification

• The American Thoracic Society recommends immediately referring patients to a speech-language pathologist for clinical evaluation followed by instrumental swallowing assessment, as bedside evaluation alone is insufficient and dysphagia carries significant mortality risk, particularly in older adults with stroke or dementia 1, 2, 3
• Oropharyngeal dysphagia presents with difficulty initiating swallowing, coughing/choking during swallowing, nasal regurgitation, wet vocal quality after swallowing, or feeling food stuck in the throat, and is diagnosed through targeted history 1, 2
• Esophageal dysphagia typically manifests as vomiting after eating or progressive difficulty with solids then liquids, suggesting mechanical obstruction, and is diagnosed through targeted history 2, 4
• Simultaneous difficulty with both solids and liquids from onset suggests a motor/motility problem, and is diagnosed through targeted history 3
• The American College of Chest Physicians recommends screening for high-risk conditions requiring urgent evaluation, including stroke, dementia, Parkinson disease, head trauma, motor neuron disease, or medications causing dysphagia 1
• Reflexive cough during eating/drinking has a sensitivity of 57-86% and specificity of 50-85% for aspiration, and is a key indicator of aspiration risk 1
• Wet or gurgly voice after swallowing is a key indicator of aspiration risk, and is diagnosed through clinical evaluation 1
• Weak voluntary cough is a key indicator of aspiration risk, and is diagnosed through clinical evaluation 1
• Need for frequent oral/pharyngeal suctioning is a key indicator of aspiration risk, and is diagnosed through clinical evaluation 1
• Recurrent pneumonia, unexplained weight loss, or malnutrition are key indicators of aspiration risk, and are diagnosed through clinical evaluation and laboratory tests 1, 3

Mandatory Instrumental Assessment

• The American Speech-Language-Hearing Association recommends proceeding immediately to videofluoroscopic swallowing study (VFSS) or fiberoptic endoscopic evaluation of swallowing (FEES) for any patient reporting swallowing difficulties, as clinical bedside evaluation alone cannot adequately assess aspiration risk or guide treatment 1, 2, 3
• Contraindications to instrumental testing include lethargy or absent swallow response on command, respiratory rate >35 breaths/min, and inability to manage oral pharyngeal secretions, and are diagnosed through clinical evaluation 1
• The speech-language pathologist will assess bolus manipulation, tongue motion, hyoid/laryngeal elevation, pharyngeal constriction, epiglottic tilt, and aspiration risk, and provide treatment recommendations based on specific swallowing impairments identified 4

Concurrent Gastroenterology Referral When Indicated

• The American Gastroenterological Association recommends referring to gastroenterology for upper endoscopy if patient has worsening GERD with dysphagia, vomiting occurs after eating, or progressive dysphagia starting with solids then liquids, as these symptoms suggest esophageal/gastric pathology rather than oropharyngeal dysphagia 2, 4, 3
• Do not delay endoscopy based on age alone, as the combination of GERD and dysphagia represents a high-risk scenario for esophageal malignancy, and is diagnosed through clinical evaluation and laboratory tests 2

Prognostic Implications and Goals of Care

• Dysphagia in elderly patients with advanced dementia carries approximately 50% mortality at 6 months, regardless of feeding interventions, and is diagnosed through clinical evaluation and laboratory tests 5, 6, 3
• Dysphagia post-stroke affects 11-50% of patients and is highly associated with reduced survival, and is diagnosed through clinical evaluation and laboratory tests 3
• Typical complications include aspiration with bronchopulmonary infections, undernutrition, extended hospital stays, and recurrent hospitalizations, and are diagnosed through clinical evaluation and laboratory tests 5
• Early goals of care discussions are recommended, as dysphagia can serve as a prompt to explore values near end of life, particularly in dementia or stroke patients where it predicts reduced survival, and are facilitated through patient-centered care 6, 3

Nutritional Support Decision-Making

• Enteral nutrition is recommended to ensure energy and nutrient supply and maintain or improve nutritional status in patients with neurological dysphagia requiring long-term support, and is prescribed through clinical evaluation and laboratory tests 5
• Percutaneous endoscopic gastrostomy (PEG) should be preferred to nasogastric tube (NGT) for long-term nutritional support, as it is associated with fewer treatment failures, better nutritional status, and may be more convenient, and is prescribed through clinical evaluation and laboratory tests 5
• Tube feeding is not recommended in frail elderly who have progressed to an irreversible final stage with extreme frailty and advanced disease, and is diagnosed through clinical evaluation and laboratory tests 5

Quality of Life Considerations

• Dysphagia significantly reduces quality of life through malnutrition, dehydration, aspiration pneumonia risk, social isolation, and discomfort with eating, and is diagnosed through clinical evaluation and patient-reported outcomes 6, 3
• Future evaluations and interventions should include standard measures of impact on quality of life, and are facilitated through patient-centered care 6

Interprofessional Coordination

• Nutritional therapy and swallowing therapy must be closely coordinated to ensure optimal patient outcomes, and are facilitated through interprofessional collaboration 5
• Caregiver education and training is critical for carryover of swallowing recommendations and dietary modifications, and is facilitated through patient-centered care 2
