| dc.description.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.
