Transurethral water vapor therapy for treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia: a cost-minimization and budget impact analysis from an Italian healthcare perspective

BACKGROUND: The aim of this study was to compare the costs and budget impact of adopting water vapor thermal therapy with the Rezūm™ System, for treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) to transurethral resection of the prostate (TURP), from an Italian hospital healthcare perspective. METHODS: A Markov model (4-year time horizon, 3-month cycle length), developed to support a submission to the National Institute of Health and Care Excellence (NICE) in England, was adapted to an Italian payer perspective. A cost minimization analysis was conducted, assuming equal efficacy between both therapies. Net difference in costs per patient was reported, considering procedure, adverse events and retreatment costs. Probabilistic and deterministic sensitivity analyses considered the uncertainty of the results. Population data and market share distribution assumptions were applied to a cohort of Italian patients treated in one year to report the budget and capacity impact of increased use of Rezūm. RESULTS: Over 4 years, the costs per patient with Rezūm were €2072 compared to €2836 with TURP, resulting in net savings of €764. Sensitivity analyses showed that this conclusion was robust. Replacing 10% of TURP procedures with Rezūm generates cost-savings of € 7,139,549 over 4 years and saves 4671 theatre hours and 26,856 bed days in one year. Replacing 30% of BPH surgical procedures with Rezūm generates cost-savings to € 21,418,647 over 4 years, saves 14,012 theatre hours and 80,567 bed-days in one year. CONCLUSIONS: This analysis demonstrates that Rezūm is highly likely to be cost-saving compared to TURP from an Italian hospital healthcare perspective.
