Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Description of intervention(s) / exposure
This proposal involves prospective data collection from patients undergoing nerve conduction studies at the Lyell McEwin Hospital “Carpal Tunnel Syndrome clinic” to determine the clinical features and risk factors most associated with a diagnosis of carpal tunnel syndrome and response to treatment.

This involves prospective data collection using a standardised questionnaire administered both before and after nerve conduction studies are performed.

Information collected using the standardised questionnaire includes clinical symptoms and signs (such as abnormal sensation in the first 3 fingers) , medical risk factors (such as history of diabetes mellitus or thyroid disease) and pain score with the Visual Analog Scale.

Prospective data collection with a standardised questionnaire will take 5 minutes and folllow up phone calls will last between 2-3 minutes.

A prospective analysis of nerve conduction testing results will be performed to determine the likelihood of each factor contributing to the diagnosis of Carpal Tunnel Syndrome (CTS), as well as the severity of discomfort experienced during nerve conduction studies.

A follow up phone call will be performed at 6 and 12 months post-nerve conduction testing to determine the association between pain thresholds and benefit from surgery.

Statistical methods / analysis
1) The diagnostic performance of each variable (including risk factor and clinical feature) will be analyzed with descriptive statistics and diagnostic performance indicators, such as sensitivity and specificity.
2) When calculating these parameters, the presence of a particular feature (such as tingling in the first three digits) in the setting of a given diagnosis (such as carpal tunnel syndrome) will be considered a true positive result.
3) Likelihood ratios and associated confidence interval calculations will be performed using a bootstrapping method similar to that which has been described previously (with 10,000 bootstraps)
