Demographic and comorbidity information was collected. In a single visit, patients were administered the RAFIS. The results obtained with the new score were compared with those of both Wexner score and faecal incontinence quality of life scale(FIQL) questionnaire. The patient withoutinfluence of the surgeon completed the test. The role of surgeon was explaining the meaning of each section and how he had to fill. Reliability of the RAFIS score was measured using intra-observer agreement and Cronbach's alpha(internal consistency) coefficient. Multivariate analysis of the main components within the different scores was performed in order to determine whether all the scores measured the same factor and to conclude whether the information could be encompassed in a single factor. A sample size of 50 patients with faecal incontinence was estimated to be enough to detect a correlation of 0.55 or better at 5% level of significance with 80% power.RESULTS: We analysed the results obtained by 53 consecutive patients with faecal incontinence(median age 61.55 ± 12.49 years) in the three scoring systems. A total of 208 healthy volunteers(median age 58.41 ± 18.41 years) without faecal incontinence were included in the study as negative controls. Pearson's correlation coefficient between "state" and "leaks" was excellent(r = 0.92, P < 0.005). Internal consistency in the comparison of "state" and "leaks" yielded also excellent correlation(Cronbach's α = 0.93). Results in each score were compared using regression analysis and a correlation value of r = 0.98 was obtained with Wexner score. As regards FIQL questionnaire, the values of "r " for the different subscales of the questionnaire were: "lifestyle" r =-0.87, "coping/behaviour" r =-0.91, "depression" r =-0.36 and "embarrassment" r =-0.90,(P < 0.01). A multivariate analysis showed that all the scoring systems measured the same factor. A single factor may explain 80.84% of the variability of FI, so all the scoring systems measure the same factor. Patient's continence improves when RAFIS and Jorge-Wexner scores show low values and when the values obtained in the FIQL questionnaire are high.CONCLUSION: RAFIS is a valid and reliable tool to assess Faecal Incontinence.展开更多
