Study on predictive models for swallowing risk in patients with AECOPD

Area of Science:

• Pulmonary Medicine
• Gastroenterology
• Geriatrics

Background:

• Dysphagia is a recognized complication in patients experiencing acute exacerbation of chronic obstructive pulmonary disease (AECOPD).
• AECOPD patients may possess inherent risk factors contributing to the development of dysphagia.

Purpose of the Study:

• To investigate the prevalence of dysphagia risk in patients with AECOPD.
• To identify specific risk factors associated with dysphagia in this patient population.

Main Methods:

• A cross-sectional study involving 100 AECOPD patients.
• Data collection included demographics, pulmonary function, COPD Assessment Test (CAT), modified Medical Research Council (mMRC) scores, and hospitalization duration.
• Swallowing risk was evaluated using a water swallow test (WST) upon admission.

Main Results:

• 50% of the 100 AECOPD patients studied were identified as being at risk for dysphagia.
• Multivariate logistic regression revealed significant risk factors: age ≥ 74 years, mMRC score ≥ level 2, hospitalization ≥ 7 days, and use of BiPAP assisted ventilation.

Conclusions:

• AECOPD patients exhibit a significant risk for dysphagia.
• Screening for swallowing difficulties can be enhanced by considering age, mMRC scores, hospitalization duration, and BiPAP use.
• Early identification facilitates the implementation of preventative strategies for dysphagia in AECOPD patients.
