Relevance of Adopting a Hybrid Strategy Mixing Single-Use and Reusable Ureteroscopes for Stones Management: An Economic Study to Support the Best Strategy.

Endoscopic procedures such as ureteroscopy (URS) have seen a recent increase in single-use devices. Despite all the advantages provided by disposable ureteroscopes (sURSs), their cost effectiveness remains questionable, leading most teams to use a hybrid strategy combining reusable (rURS) and disposable devices. Our study aimed to create an economic model that estimated the cut-off value of rURS procedures needed to support the profitability of a hybrid strategy (HS) for ureteroscopy. We used a budget impact analysis (BIA) model that estimated the financial impact of an HS compared to 100% sURS use. The model included hospital volume, sterilization costs and the private or public status of the institution. Although the hybrid strategy generally remains the best economic and clinical option, a predictive BIA model is recommended for the decision-making. We found that the minimal optimal proportion of rURS procedures in an HS was mainly impacted by the activity volume and overall number of sterilization procedures. Private and public institutions must consider these variables and models in order to adapt their HS and remain profitable.

Switching to Single-use Flexible Ureteroscopes for Stones Management: Financial Impact and Solutions to Reduce the Cost Over a 5-Year Period.

OBJECTIVES: To assess the financial impact of switching to single-use ureteroscopes (sURS) in urolithiasis management for a hospital, over a 5-year period, and to identify possible solutions to contain or reduce it. METHODS: A Budget Impact (BI) model was designed for a public hospital performing around 200 ureteroscopies or extracorporeal shockwave lithotripsies per year. The BI was estimated as the difference between financial balances (between costs and revenues) of 2 environments (with and without sURS). The population was defined as adults treated for urolithiasis. The BI model was based on assumptions about the expected progression in the incidence of urolithiasis, and the expected change in clinical practices due to the availability of sURS. We considered the costs and revenues of hospital stays, the purchase price of sURS and the costs of digital or fiberoptic reusable ureteroscopes (rURS). Univariate and multivariate sensitivity analyses were performed. RESULTS: The cumulative 5-year financial impact of switching completely to sURS was €807,824 and €649,677 in comparison with fiberoptic and digital rURS respectively. This impact could be reduced by half or more if the health-care facility were to adopt different solutions, including negotiating the purchase price of sURS, developing outpatient activity and reducing production costs for ureteroscopy procedures. CONCLUSION: The BI model gives decision-makers a more accurate picture of the financial impact of switching to sURS and highlights ways to reduce the expected additional cost.
