Abstract: BACKGROUND: Carpal tunnel syndrome is common, and carpal tunnel syndrome-6 (CTS-6) is a validated diagnostic tool; however, its weighted scoring limits rapid use. We evaluated a simplified quick carpal tunnel syndrome-6 (QCTS-6) for diagnostic accuracy. METHODS: Carpal tunnel releases performed at a tertiary care center (January 2017-August 2024) were retrospectively identified. Preoperative presence or absence of the components of the CTS-6 were reviewed and assigned the corresponding number of points. For the QCTS-6 scoring system, 0 or 1 point was assigned for a total score out of 6. Preoperative electromyography (EMG)/nerve conduction study (NCS) results were collected when available. Descriptive statistics, Spearman's Rho correlations, and diagnostic ratio tests were performed. RESULTS: = 0.976). Patients with QCTS-6 score of 3 or more exhibited the presence of all questionnaire components and severe EMG/NCS findings at higher rates, with 98.2% of them having CTS-6 scores greater than 12. Diagnostic ratio testing identified numbness in the median nerve territory, nocturnal numbness, and loss of 2-point discrimination as the most balanced predictive factors. CONCLUSIONS: The QCTS-6 scoring system can be a valid alternative to the traditional CTS-6. Owing to its uniform scoring, it can allow for efficient workup without necessitating EMG/NCS. A score of 3 or more may serve as a sensitive cutoff for carpal tunnel syndrome.
