Study on predictive models for swallowing risk in patients with AECOPD

Abstract

BACKGROUND: The risk of swallowing is considered a complication in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). However, AECOPD may have risk factors for swallowing. METHODS: This study included 100 patients with AECOPD. General Data, lung function, COPD assessment test (CAT) and Modified Medical Research Council Dyspnea Scale (mMRC) were collected. The questionnaire survey was conducted by uniformly trained investigators using standard and neutral language, and swallowing risk was evaluated on the day of patient admission. RESULTS: Among the 100 included patients, 50(50%) were at risk of swallowing. Multivariate analysis using logistic regression analysis showed that age ≥ 74, mMRC≥2, hospitalization days≥7and the use of BIPAP assisted ventilation were important influencing factors for swallowing risk in patients with AECOPD. CONCLUSION: Patients with AECOPD are at risk for swallowing, assessing age, mMRC, hospitalization days, and the use of BIPAP assisted ventilation can be used to screen for swallowing risk, thus contributing to the implementation of early prevention measures.
