Brief summary

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.

Design outcomes

Primary

MeasureTime frameDescription
RSI Score at Baseline:RSI Score at BaselinePatients 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.
RSI Score at Days 10-14Days 10-14Patients 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.
RFS Score at Baseline:RFS Score at BaselineDevice: 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.
RFS Score at Days 10-14Days 10-14Device: 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.
Reliability and validity of RSI at Baseline:RSI Score at BaselineReliability 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.

Test - retest reliability of the RSI questtionaireDays 10-14Test - 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).
