Clinical Trial Summary

Title:

Inter-rater reliability of the reflux finding score based on endoscopic laryngeal findings in the diagnosis of laryngopharyngeal reflux disease

Participants:

Voluntary participants after invitation among members (a total of about 40 gastroenterologists) of Gangwon Branch of Korean Society of Gastrointestinal Endoscopy and an otorhinolaryngologist

Primary endpoint:

Interrater reliability (Kappa coefficient) on the sum of reflux finding score more than 7 points between an otorhinolaryngologist and gastroenterologists (7 points means the cut-off value for the diagnosis of laryngopharyngeal reflux disease)

Secondary endpoint:

Agreement (%) on 8 items of reflux finding score for laryngopharygeal reflux among gastroenterologists


Clinical Trial Description

Study Design

1. Recruitment of doctor participants: introduction by e-mail

2. Education on reflux finding score - standardized materials (instructional video)

3. PRETEST (15 pictures) / feedback (at-a-glance assessment format)

4. TEST 1 (50 pictures) - Acess format including 8 items at each pictures

5. Feedback education (individualized intruction of an otorhinolaryngologist)

6. TEST 2 (50 pictures) - Acess format including 8 items at each pictures

7. Test-Retest reliability - repeat Test 2 with 1 week interval (Participants should take retest of TEST 2 with the concealment of the answer)

8. Analysis ;
