Brief Summary:
The purpose of this study was to determine whether the provision of societal cost information affects patients' decisions whether or not to undergo surgical management in carpal tunnel syndrome, using a hypothetical scenario.

Condition or disease Intervention/treatment Phase
Carpal Tunnel Syndrome Other: Societal cost Not Applicable

Detailed Description:
Given the large societal costs of carpal tunnel surgery and existence of a relatively inexpensive treatment option, carpal tunnel release provides fertile ground for testing whether societal costs can influence patient decision-making in hand surgery. Such work would inform future efforts to reduce societal healthcare costs by elucidating whether appeals to societal cost are effective at driving stewardship of limited healthcare resources at the patient level. In this study, the investigators aimed to answer this question by presenting participants with a hypothetical scenario in which the participants had to choose between surgery and wrist bracing for carpal tunnel syndrome. Participants were randomized into two cohorts and societal cost information was presented to the intervention group. The effect of societal cost information on treatment choice is assessed, along with participants' healthcare attitudes.

Primary Purpose: Treatment
Official Title: Does Societal Cost Information Affect Patient Decision-Making in Carpal Tunnel Syndrome: A Randomized Controlled Trial

Arm Intervention/treatment
Experimental: Cost group
These patients reviewed total societal costs associated with carpal tunnel release.
Other: Societal cost
Annual societal cost information to the US for carpal tunnel release surgery was displayed.

No Intervention: No cost group
These patients did not review total societal costs associated with carpal tunnel release.

Primary Outcome Measures :
  1. Number of participants choosing carpal tunnel release or splinting [ Time Frame: Immediately after reading the hypothetical scenario ]
    Choice for carpal tunnel release over splinting. All participants were presented a hypothetical case of mild carpal tunnel syndrome. The scenario described (nocturnal) symptoms of numbness and tingling and two treatment choices: carpal tunnel release or wrist splinting. In addition, participants were randomized to review total annual societal cost information for CTR procedures in the United States. After reviewing the case, participants were asked to indicate if they would choose surgery (more expensive) or splinting (less expensive). Scoring was measured on a 6-point ordinal Likert scale (ranging from 1="Definitely not" to 6="Definitely").
