Cost Information on Carpal Tunnel Syndrome Treatment Decisions

Study Overview
=================
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.

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.

Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Patients were randomized in an intervention group that reviewed societal costs associated with carpal tunnel release and a control group that did not.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cost group<br>These patients reviewed total societal costs associated with carpal tunnel release. | Other: Societal cost<br>* Annual societal cost information to the US for carpal tunnel release surgery was displayed.<br>|
| No Intervention: No cost group<br>These patients did not review total societal costs associated with carpal tunnel release. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of participants choosing carpal tunnel release or splinting | 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). | Immediately after reading the hypothetical scenario |
