Perbandingan Uji Diagnostik Kuesioner Sindrom Terowongan Karpal Boston dengan Kuesioner Kamath dan Stothard pada Pasien Sindrom Terowongan Karpal di Rumah Sakit Adam Malik Medan

Abstract

Background:: Accurate diagnosis of Carpal Tunnel Syndrome (CTS) is crucial for appropriate treatment to improve patients' quality of life. However, not all healthcare facilities have nerve conduction testing equipment, and the cost of testing is high, resulting in many cases going undiagnosed. Given these limitations, a questionnaire or instrument has been developed to assist clinicians in diagnosing CTS. Objective: To determine the diagnostic accuracy of the Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ) compared to the Kamath and Stothard Questionnaire (KSQ) at Adam Malik Hospital in Medan. Metode Penelitian: This study used an observational analytical design on 51 patients (67 hands were examined) with CTS at Adam Malik Hospital in Medan who met the research criteria and were confirmed by nerve conduction examination. Statistical analysis was then performed to assess sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, accuracy, and AUC and ROC values. Results: There were 51 research subjects, with the majority being female (66.7%). The diagnostic test results for KSTK-B showed a sensitivity of 83.6%, specificity of 66.7%, PPV of 92.0%, NPV of 47.0%, LR+ of 2.5, LR- of 0.25, accuracy of 80.5%, and AUC of 0.752. Meanwhile, KKS had a sensitivity of 87.2%, specificity of 75.0%, PPV of 94.1%, NPV of 56.2%, LR+ of 3.49, LR- of 0.17, accuracy of 85.1%, and AUC of 0.811. Conclusion: In this study, the Kamath and Stothard Questionnaire had better sensitivity, specificity, PPV, NPV, LR+, LR-, accuracy, AUC value, and ROC compared to the Boston Carpal Tunnel Syndrome Questionnaire in diagnosing Carpal Tunnel Syndrome.
