Incidence and Related Factors to Developing Dysphagia in Hospitalized COVID-19 Patients

Objectives: Since December 2019, COVID-19 spread worldwide. Patients with COVID-19 are at high hazard for dysphagia. This study investigates the incidence of dysphagia in COVID-19 patients admitted to the intensive care unit (ICU) and identifies predictors of dysphagia in COVID-19 patients. Methods: This prospective study analyzed 100 COVID-19 patients admitted to the ICU of Firoozgar Hospital in Tehran City, Iran. The demographic and clinical features of the eligible patients were collected. Dysphagia and cognition were evaluated according to the Persian version of functional oral intake (FOIS-P) status and the Rancho Los Amigos scale (RLAS). The qualitative variables are described in frequency and percentages and the quantitative variables are illustrated by Mean±SD. Also, univariate and multivariate cox regression was performed to predict possible relations between demographic and clinical variables with dysphagia. Results: A total of 100 COVID-19 patients (43.3±13.3 years, 55% were men) who were admitted to the ICUs were appraised by speech and language pathologists. Meanwhile, 70% of the subjects had at least one comorbidity, with the most common ones being diabetes, hypertension, and obesity. Also, 74% of patients were on invasive mechanical ventilation (60% through endotracheal tube and 40% through tracheostomy). In addition, 57% of patients presented dysphagia. Age (odd ratio (OR)=1.127; 95% confidence interval (CI), 1.019%, 1.247%; P=0.02) and level of consciousness (OR=0.393; 95% CI, 0.178%, 0.868%; P=0.021) were predictors of dysphagia.  Discussion: Dysphagia was prevalent among COVID-19 patients predicted by age and level of consciousness. Early evaluation of suspected patients is required for timely and efficient interventions to avoid further problematic issues and progress their quality of life.
