Using Odih-Score (Modified Klotz Score) for quality of defecation after anorectal malformation following posterior sagittal anorectoplasty (PSARP): Study of validation

Abstract

Abstract* Objective The diagnostic scale or score is a clinical assessment tool used to determine diagnosis and evaluate further therapy results. The Klotz Score is a previous score modified to create a new instrument, the Odih-score. This new instrument is specifically designed to evaluate the quality of defecation success after operative anorectal malformation and is expected to be simpler and easier to apply in research hospitals. Its primary use is to evaluate the quality of defecation in post-PSARP anorectal malformation patients. Method The study conducted between 2016 and 2021, a longitudinal prospective study was conducted at RSUD Arifin Achmad Pekanbaru Riau Indonesia. The study aimed to validate the reliability of the Odih-Score (Modified Klotz Score) research instrument for evaluating defecation quality in post-PSARP anorectal malformation patients. Pearson validation test and Cronbach alpha reliability test were used as parameters for the validation, while the sensitivity and specificity of diagnostic tests were evaluated using research instrument (IBM SPSS Statistics version 25) The research was approved by the Ethical Clearance Board of the Faculty of Medicine, University of Riau, under reference number No.031/UN.19.5.1.1.8/UEPKK/2019. Results The analysis of the validation test results indicates that the Odih-Score is statistically significant (Sig.<0.05) and has a greater r-count value (0.573-0.790) than the r-table value (0.202). The research reliability test also shows a high level of reliability (Cronbach alpha 0.814) for all five items of the Odih-Score instrument. Further, the sensitivity and specificity test as a diagnostic test resulted in an AUC value of 0.798, with an Odih-Score cut-off point of 11. Conclusion Odih-Score (Modified Klotz’s score) is considered valid and reliable and can be used as a diagnostic test instrument to evaluate the quality of post-anorectal Malformation defecation with PSARP.
