Comparison Between Image-Guided and Landmark-Based Glenohumeral Joint Injections for the Treatment of Adhesive Capsulitis: A Cost-Effectiveness Study
2018
OBJECTIVE. The purpose of this study was to determine the cost-effectiveness of landmark-based and image-guided intraarticular steroid injections for the initial treatment of a population with adhesive capsulitis. MATERIALS AND METHODS. A decision analytic model from the health care system perspective over a 6-month time frame for 50-year-old patients with clinical findings consistent with adhesive capsulitis was used to evaluate the incremental cost-effectiveness of three techniques for administering intraarticular steroid to the glenohumeral joint: landmark based (also called blind), ultrasound guided, and fluoroscopy guided. Input data on cost, probability, and utility estimates were obtained through a comprehensive literature search and from expert opinion. The primary effectiveness outcome was quality-adjusted life years (QALY). Costs were estimated in 2017 U.S. dollars. RESULTS. Ultrasound-guided injections were the dominant strategy for the base case, because it was the least expensive ($1280) and ...
