Brief Summary:
This study will complete a randomized controlled trial to quantitatively measure patient decisional conflict (Decisional Conflict Scale) in 150 patients treated for CTS with the tool compared to 150 patients treated with standard care. The investigators hypothesize patients treated for CTS will have lower decisional conflict with the tool.

Condition or disease Intervention/treatment Phase
Carpal Tunnel Carpal Tunnel Syndrome Carpal Tunnel Syndrome Left Carpal Tunnel Syndrome Right Carpal Tunnel Syndrome Bilateral Other: Preference Elicitation tool Not Applicable

Detailed Description:
The investigators will measure decisional conflict in 150 new patients being evaluated for CTS with the tool compared to 150 patients being evaluated for CTS with standard care. Those patients randomized to receiving the tool will use it to identify their preferences for certain attributes of care. Patients will then be presented with their preference data and the surgeon will have a discussion with the patient regarding CTS. Surgeons will have their standard discussion with the patients randomized to the standard care group (no tool). The tool will be operationalized on a Health Insurance Portability and Accountability Act compliant data platform, such as Qualtrics, and no identifiable data will be collected. De-identified data will be shared from study cites with our team at Stanford. This data will be backed up on a computer encrypted by Stanford.

None- normal care
Experimental: Intervention
Patients will use a preference elicitation tool to determine their preferences for diagnosis and treatment of CTS
Other: Preference Elicitation tool
A preference elicitation tool for carpal tunnel syndrome

Primary Outcome Measures :
  1. Decisional Conflict Scale [ Time Frame: Immediately after using tool ]

    Name: Decisional Conflict Scale Measures: uncertainty in choosing options; modifiable factors contributing to uncertainty such as feeling uninformed, unclear about personal values and unsupported in decision making; and effective decision making such as feeling the choice is informed, values-based, likely to be implemented and expressing satisfaction with the choice.

    16 statements with 5 response categories Scoring: total scale-0 (no decisional conflict) to 100 (extreme decisional conflict) lower values indicate lower decisional conflict- i.e. a better outcome for use of the tool.

    Calculation: Summed, divided by # of items, multiplied by 25
