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 most effective (0.4096 QALY) strategy of the three options overall. The model was sensitive to the probabilities of getting the steroid into the joint by means of blind, ultrasound-guided, and fluoroscopy-guided techniques and to the costs of the ultrasound-guided and blind techniques. Two-way sensitivity analyses showed that ultrasound-guided injections were favored over blind and fluoroscopy-guided injections over a range of reasonable probabilities and costs. Probabilistic sensitivity analysis showed that ultrasound-guided injections were cost-effective in 44% of simulations, compared with 34% for blind injections and 22% for fluoroscopy-guided injections and over a wide range of willingness-to-pay thresholds.
Conclusion:
Ultrasound-guided injections are the most cost-effective option for the initial steroid-based treatment of patients with adhesive capsulitis. Blind and fluoroscopy-guided injections can also be cost-effective when performed by a clinician likely to accurately administer the medication into the correct location.
