Abstract:
Objective The consistency of reflux finding score (RFS) was studied by three different level of throat physicians.Methods One hundred and ten laryngeal photos were chosen to assess the RFS test-retest reliability on two separate occasions at least more than one week.Results The mean total RFS scores for doctor A were 9.05 ±2.54,doctor B were 8.80 ±2.20,doctor C were 8.98 ±2.21 at the initial screening,and 9.20 ±2.47,9.03 ± 2.14 and 8.91 ± 2.30 respectively at the repeat evaluation.The testretest reliability of total RFS scores of three doctors were 0.860,0.800 and 0.837 respectively,P all ＜0.001.The test-retest reliability of each item scores for doctor A were from 0.662 to 1.000,doctor B were from 0.486 to 1.000 and doctor C were from 0.613 to 1.000.There were no differences in the total RFS scores comparing among each evaluation of the three doctors (x2 =1.553,P =0.907).Total RFS scores more than 7 were considered as abnormal.The interobsever consistency was as follows:A with B was 83.6％ (K=0.617,P=0.000),A with C was 85.5％ (K =0.644,P =0.000),B with C was 89.1％ (K=0.720,P =0.000).The intraobserver consistency was 91.8％ (K =0.807,P =0.000),81.8％ (K =0.534,P =0.000),90.9％ (K =0.741,P =0.000) respectively.Conclusions The result of this study shows that the assessment of RFS is not influenced by different educational backgrounds and clinical experience.RFS can be applied widely in China.
