ABSTRACT
Background
COVID-19 comprises a respiratory infection resulting from contamination by SARS-CoV-2, with acute respiratory failure being one of its main characteristics, leading to a high frequency of orotracheal intubation (OTI), which in turn increases the risk for dysphagia. Since this can lead to pulmonary impairment, knowing the real occurrence of dysphagia in part of the Brazilian population and its associations allows early and effective clinical management of the multidisciplinary team in relation to patients.
Objective
To verify the occurrence of dysphagia in COVID-19-positive adult patients in two Brazilian reference hospitals in the care of the pandemic.
Methods
This was a prospective, longitudinal observational study carried out in two private hospitals in Brazil, both references in the care of patients with coronavirus isolation. Data were initially collected by consulting the medical records of each patient. Information was collected regarding sex, age, previous diseases, COVID-19 testing, and the OTI period. After data collection, the clinical speech-language assessment of swallowing for each patient was carried out using the adapted Gugging Swallowing Screen (GUSS), the ASHA NOMS and the Functional Oral Intake Scale (FOIS).
Results
A total of 129 participants were evaluated, with a mean age of 72 years. According to the GUSS scale, 9.3% of the patients presented normal/functional swallowing, while 90.7% presented dysphagia, with mild dysphagia in 17.05%, moderate dysphagia in 33.33%, and severe dysphagia in 37.98%. As for the results of the ASHA NOMS, the majority (36.5%) of the patients were at level 1, which represents the patient who is not able to receive his or her food supply orally, having the need to use tube feedings. This is in line with the results observed with the FOIS scale, whereby most patients (42.1%) were classified as Level I, when food intake occurs exclusively through feeding tubes, with no oral supply. Of the 129 participants, 59% of them required OTI. When comparing the time of OTI and the severity of dysphagia, there was a statistically significant difference, with more severe dysphagia, the longer the patient remained intubated.
Conclusion:
There is a high incidence of oropharyngeal dysphagia in patients with COVID-19, with increased severity during longer periods of OTI.
