Validity and Reliability of the Turkish Version of the Post-Extubation Dysphagia Screening Tool

Abstract

Background and Purpose:Patients who have been intubated ≥48 hours are at risk of dysphagia. Evaluation of swallowing before starting oral feeding after extubation is necessary to prevent aspiration and the problems caused by aspiration. The Post-Extubation Dysphagia Screening tool is a validated and reliable tool used to evaluate extubation-induced dysphagia. This study was conducted to evaluate the validity and reliability of the Post-Extubation Dysphagia Screening Tool for the Turkish population.Methods:The study had a methodological design and was carried out with 50 patients followed in the intensive care unit of a public hospital. The study was carried out in four stages: (1) language validity, (2) content validity, (3) establishing interrater reliability by agreement with two observers (intensive care nurse and intensivist), and (4) establishing sensitivity and specificity with the intensive care nurse and intensivist.Results:The overall content validity index was 0.91, indicating content validity. Interrater reliability was established (Cohen’s g = 0.93). The prevalence of post-extubation dysphagia was 42%, and the sensitivity of the Post-Extubation Dysphagia Screening Tool was 82% and the specificity was 64%.Implications for Practice:The Turkish version of the Post-Extubation Dysphagia Screening Tool exhibited good evidence of validity and reliability and was determined important as it can help nurses evaluate post-extubation dysphagia in intensive care patients. The use of this tool by a nurse reduces the risk of unsafe oral intake among patients after prolonged intubation. This tool allows accurate assessment of dysphagia and initiation of early and safe oral feeding in critical care patients.
