Kazakh Version of Reflux Symptom Index

Kazakh Medical University of Continuing Education248 enrolled

Overview

Reflux symptoms index (RSI) were developed to identify a clinical index of suspicion for laryngopharyngeal reflux (LPR) in patients with ear, nose, and throat symptoms. RSI is an efficient diagnostic tool for LPR/ It is easy to use, even for those who know little about LPR. It does not require special equipment or examinations and is inexpensive. Thus, it can be considered highly efficient and cost-effective. The study will focus on translating and testing the RSI into Kazakh language and comparing its results in healthy people and people with laryngopharyngeal reflux.

Outcomes

Primary Outcomes

RSI Score at Baseline:

Patients will be asked to complete the Reflux Symptom Index questionnaire. An analysis of the results of the effectiveness of this method in patients with complaints of sore throat, coughing, burning sensation in the throat, cough, frequent sore throat, difficulty swallowing, lump in the throat, feeling of a foreign body in the throat, voice change, heartburn, belching will be carried out. The severity of the problem is calculated as the summation of all points. The problem is absent if the summation of points is 0. The problem is serious if the summation of points is 5. Total score ranges from 0-45; of which 0-12 is considered no laryngopharengeal reflux, above 13 points for the presence of laryngopharyngeal reflux.

Time frame: RSI Score at Baseline

RSI Score at Days 10-14

Time frame: Days 10-14

RFS Score at Baseline:

Device: Endoscopic laryngoscopy Video laryngoscopy and assessment of the presence / severity of the symptoms- Reflux finding score. Evaluation results range from 0 to 4, where 0 is an indicator of no problem, and 4 is an indicator of a serious problem. Total score ranges from 0-48; of which 0-6 is considered no laryngopharengeal reflux, above 7 points for the presence of laryngopharyngeal reflux.

Time frame: RFS Score at Baseline

RFS Score at Days 10-14

Device: Endoscopic laryngoscopy Video laryngoscopy and assessment of the presence / severity of the symptoms - Reflux finding score and will be used as a gold standard of diagnosis of laryngopharengeal reflux. Evaluation results range from 0 to 4, where 0 is an indicator of no problem, and 4 is an indicator of a serious problem. Total score ranges from 0-48; of which 0-6 is considered no laryngopharengeal reflux, above 7 points for the presence of laryngopharyngeal reflux.

Time frame: Days 10-14

Reliability and validity of RSI at Baseline:

Reliability and validity of RSI at Baseline using Cronbach's alpha test to check the internal consistency for all the 9 items. Total score ranges from 0-45; of which 0-12 is considered no laryngopharengeal reflux, above 13 points for the presence of laryngopharyngeal reflux.

Time frame: RSI Score at Baseline

Laryngopharyngeal reflux diagnosis at baseline

Video laryngoscopy and assessment of the presence / severity of the symptoms- Reflux finding score. Evaluation results range from 0 to 4, where 0 is an indicator of no problem, and 4 is an indicator of a serious problem. Total score ranges from 0-48; of which 0-6 is considered no laryngopharengeal reflux, above 7 points for the presence of laryngopharyngeal reflux.

Test - retest reliability of the RSI questtionaire

Test - retest reliability of the RSI questtionaire at Days 10-14. Test-retest reliability coefficients vary between 0 and 1, where: 1 : perfect reliability, 0.9: excellent reliability, 0.8 \< 0.9: good reliability, 0.7 \< 0.8: acceptable reliability, 0.6 \< 0.7: questionable reliability, 0.5 \< 0.6: poor reliability, \< 0.5: unacceptable reliability, 0: no reliability. On this scale, a correlation of .9(90%) would indicate a very high correlation (good reliability) and a value of 10% a very low one (poor reliability).
