Trial Outcomes & Findings for Swallowing Function Before and After Surgery for Thyroid Goiter (NCT NCT00205348)

NCT ID: NCT00205348

Last Updated: 2018-02-28

Results Overview

The swallowing quality of life (SWAL-QOL) validated outcomes assessment tool will be used before and one year after surgery to measure changes in swallowing-related QOL in patients undergoing thyroid surgery. The SWAL-QOL is a 44 item tool that asks patients to rate several factors about 10 quality-of-life concepts related to swallowing on a 5 point scale.Data were collected on demographic and clinicopathologic variables, and comparisons were made to determine the effect of surgery on patients' perceptions of swallowing function. A score of 0 represents the least favorable state, and 100 the most favorable. It has been validated and has favorable psychometric properties, including high internal-consistency reliability and reproducibility. The scales of the instrument differentiate patients with oropharyngeal dysphagia from normal swallowers and are sensitive to clinically-relevant differences in dysphagia severity in patients with medically and surgically treated conditions.
