FraMaDySc: dysphagia screening for patients after surgery for head and neck cancer

Abstract

Abstract Purpose Oropharyngeal dysphagia is one of the most common postoperative consequences in head and neck cancer patients. Above all, these patients often suffer from aspiration and limitations of oral intake. However, no reliable dysphagia screening is available for this target group. This study aimed to develop and validate a screening, FraMaDySc, based on a water swallow test (WST) for the identification of postsurgical patients with a risk of aspiration, limitations of oral intake, and, as their derivate, a relevant oropharyngeal dysphagia in general (OD) that constituted the main reference standard. Methods A total of 184 postsurgical head and neck cancer patients were tested with a WST. The patients were, on average, 62 years old and predominantly male (71%). After WST, they underwent Fiberoptic Endoscopic Evaluation of Swallowing (FEES®). FEES® results were dichotomized by Penetration aspiration scale and Functional oral intake scale. Patients with a “fail” result on one of these two scales were classified as having OD. Quality criteria of WST were quantified by means of cross-tabulation with FEES® results. Results OD was found in 65% of patients, aspiration in 44%, limitations of oral intake in 56%. WST delivered a “fail” result in 65% of patients. WST showed sensitivity 91% and specificity 88% for OD. Quality criteria for aspiration (sensitivity 64%, specificity 93%) and limitations of oral intake (sensitivity 80%, specificity 87%) were lower. Conclusion FraMaDySc is a standardized, quick, and valid WST and therefore an excellent screening tool for the identification of OD in postoperative head and neck cancer patients.
