Number of patient reported dysphagia events measured by Eat-10 assessment tool |
Number of patient reported dysphagia events (incidence & severity ) is measured by Eating Assessment Tool (EAT-10) post surgery at day1 which is self-administered, symptom-specific outcome instrument for dysphagia. It consists of ten statements that a patient rates on a scale of 0-4, with 0=no problem to 4=severe problem. |

Dysphagia as measured by SWAL-QOL assessment tool |
Dysphagia is measured by SWAL-QOL assessment tool which is designed to find out how one's swallowing problem has been affecting their day-to-day quality of life. Scoring in each domain is calculated by the sums of scores for each item expressed as a percentage of the maximum possible domain score. A total SWAL-QOL score is derived by summing each domain score and dividing by 10 giving a total SWAL-QOL score that ranges between 0 and 100 (worst-best). |
