Clinical Trial: Inter-rater Reliability of the Reflux Finding Score Among Gastroenterologists
Study Status: Completed
Recruit Status: Completed
Study Type: Observational
Official Title: Inter-rater Reliability of the Reflux Finding Score Based on Endoscopic Laryngeal Findings in the Diagnosis of Laryngopharyngeal Reflux Disease
Brief 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
Detailed Summary:
Study Design
- Recruitment of doctor participants: introduction by e-mail
- Education on reflux finding score - standardized materials (instructional video)
- PRETEST (15 pictures) / feedback (at-a-glance assessment format)
- TEST 1 (50 pictures) - Acess format including 8 items at each pictures
- Feedback education (individualized intruction of an otorhinolaryngologist)
- TEST 2 (50 pictures) - Acess format including 8 items at each pictures
- Test-Retest reliability - repeat Test 2 with 1 week interval (Participants should take retest of TEST 2 with the concealment of the answer)
- Analysis
