Objective
To determine the cost-effectiveness of rotator cuff hydroxyapatite deposition disease (HADD) treatments.
Method
A 1-year time horizon decision analytic model was created from the US healthcare system perspective for a 52-year-old female with shoulder HADD failing conservative management. The model evaluated the incremental cost-effectiveness ratio (ICER) and net monetary benefit (NMB) of standard strategies, including conservative management, ultrasound-guided barbotage (UGB), high- and low-energy extracorporeal shock wave therapy (ECSW), and surgery. The primary effectiveness outcome was quality-adjusted life years (QALY). Costs were estimated in 2022 US dollars. The willingness-to-pay (WTP) threshold was $100,000.
Results
For the base case, UGB was the preferred strategy (0.9725 QALY, total cost, $2199.35, NMB, $95,048.45, and ICER, $33,992.99), with conservative management (0.9670 QALY, NMB $94,688.83) a reasonable alternative. High-energy ECSW (0.9837 QALY, NMB $94,805.72), though most effective, had an ICER of $121, 558.90, surpassing the WTP threshold. Surgery (0.9532 QALY, NMB $92,092.46) and low-energy ECSW (0.9287 QALY, NMB $87,881.20) were each dominated. Sensitivity analysis demonstrated that high-energy ECSW would become the favored strategy when its cost was < $2905.66, and conservative management was favored when the cost was < $990.34. Probabilistic sensitivity analysis supported the base case results, with UGB preferred in 43% of simulations, high-energy ECSW in 36%, conservative management in 20%, and low-energy ECSW and surgery in < 1%.
Conclusion
UGB appears to be the most cost-effective strategy for patients with HADD, while surgery and low-energy ECSW are the least cost-effective. Conservative management may be considered a reasonable alternative treatment strategy in the appropriate clinical setting.
