Abstract: Patients in intensive care units are often at increased risk for oropharyngeal dysphagia following prolonged endotracheal intubation. Although reported incidence can be high, it varies widely. Purpose of this systematic review to find out: the incidence of dysphagia following endotracheal intubation, the association between dysphagia and intubation time. There were fourteen databases were searched with using keywords dysphagia, deglutition disorders, and intubation. Inclusion criteria set for the study is that an adult participants who underwent intubation and clinical assessment for dysphagia. Exclusion criteria were case series (n <10), dysphagia determined by patient report, patients with tracheostomies, esophageal dysphagia, and/or diagnoses known to cause dysphagia. A total of 1,489 citations were identified, of which 288 articles were reviewed and 14 met inclusion criteria. The studies were heterogeneous in design, swallowing assessment, and study outcome; therefore, we present findings descriptively. Dysphagia frequency ranged from 3% to 83% and intubation duration from 124.8 to 346.6 mean hours. The highest dysphagia frequencies (83% 62%, 56%, and 51%) occurred following prolonged intubation and included patients across all diagnostic subtypes.
