Objectives: To estimate the willingness-to-pay (WTP) for symptom relief of tennis elbow and examine whether WTP is related to injury characteristics, clinical outcomes, or other socio-demographic factors. Methods: This cross-sectional WTP, contingent valuation study was performed alongside a randomised controlled trial comparing the addition of physiotherapy to corticosteroid injection in 165 participants with tennis elbow. The contingent value scenario constructed required participants to decide the monetary value (AUD) they would pay for a quick and non-invasive new treatment for relief of their elbow condition. Participants were told to consider that their symptoms would persist for the next 12 months if left untreated. The efficacy of this new treatment was defined as complete recovery in 50% of people treated. Two WTP approaches (bidding game and binary response) were administrated in blocks of 15 consecutive participants. For both methods, participants were randomly allocated a starting bid from values of $50, $650, $1250 or $1850. Results: The bidding game approach was performed in 73 participants. WTP values ranged from $50 – 10000 [median WTP (IQR): $695 ($390, $940)]. WTP was significantly associated with an individual’s gross income, greater pain and disability and a worsening condition. The binary response approach was performed in 87 participants. All participants accepted a $50 bid, while more than half accepted $650 and $1250 bids. Using this approach, participants were more likely to accept higher values if they had experienced greater pain and disability, a worsening condition and reduced pain-free grip of their affected arm. Conclusions: This study examined the economic value that participants with tennis elbow ascribe to relief of their condition. The relationship between this monetary value and an individual’s injury characteristics and income was also demonstrated. In future work, we propose to compare these WTP estimates with indicators of health-related quality-of-life, which were also collected during this study.

Abstract
Objectives: To estimate the willingness-to-pay (WTP) for symptom relief of tennis elbow and examine whether WTP is related to injury characteristics, clinical outcomes, or other socio-demographic factors. Methods: This cross-sectional WTP, contingent valuation study was performed alongside a randomised controlled trial comparing the addition of physiotherapy to corticosteroid injection in 165 participants with tennis elbow. The contingent value scenario constructed required participants to decide the monetary value (AUD) they would pay for a quick and non-invasive new treatment for relief of their elbow condition. Participants were told to consider that their symptoms would persist for the next 12 months if left untreated. The efficacy of this new treatment was defined as complete recovery in 50% of people treated. Two WTP approaches (bidding game and binary response) were administrated in blocks of 15 consecutive participants. For both methods, participants were randomly allocated a starting bid from values of $50, $650, $1250 or $1850. Results: The bidding game approach was performed in 73 participants. WTP values ranged from $50 – 10000 [median WTP (IQR): $695 ($390, $940)]. WTP was significantly associated with an individual’s gross income, greater pain and disability and a worsening condition. The binary response approach was performed in 87 participants. All participants accepted a $50 bid, while more than half accepted $650 and $1250 bids.
