Dysphagia leads to swallowing\u2010related complications, in turn leading to COPD exacerbation. Dysphagia screening is recommended; however little is known of its utility in detecting a COPD phenotype at risk for exacerbation. The simple swallowing provocation test (SSPT), considered to be a standard screening test, requires specific equipment, physician skill and patient discomfort.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives<\/jats:title><jats:p>The aim of this study was to find an easier and less invasive measure to screen for dysphagia in patients with COPD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively reviewed patients with COPD who were screened for dysphagia [Repetitive saliva swallowing test (RSST), water swallowing test (WST), SSPT and a questionnaire] from June to November 2016. The patients were classified into two groups according to the presence of COPD exacerbation in the past 3 years (ie, exacerbation and non\u2010exacerbation group), and the dysphagia screening results were compared between the groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 80 cases included, 42 had 1 or more exacerbations in the past 3 years (exacerbation group), and 38 had none (non\u2010exacerbation group).
