Vulnerability to Financial Toxicity From Stone Surgery

Financial toxicity has been described in stone formers; however, little is understood regarding its causes and how it may relate to stone surgery. We therefore aimed to longitudinally describe markers of financial strain in stone formers from the preoperative to postoperative time points.

A prospective cohort study was conducted from January 2022 to April 2023. Patients were enrolled in the waiting area prior to undergoing elective ureteroscopy or percutaneous nephrolithotomy. Participants completed The Commonwealth Fund's Biennial Health Insurance Survey at this time point and at 30 days postoperatively. Items were preselected from the survey to capture markers of financial strain due to health care costs.

One hundred nine participants were enrolled. White (70%), college-educated (62%), and privately insured (72%) patients comprised the majority of participants. Despite these traditionally protective sociodemographic features, 42% of patients reported some marker of financial strain at the preoperative time point. Patients with Medicaid reported even higher financial stress (67%). Furthermore, 46% of patients did not know their deductible amount. Response rate was low at 30 days postoperatively (35%) but suggested some patients were experiencing new financial strains.

This paper shows that a significant proportion of stone patients are already displaying markers of financial strain from health care bills even prior to surgery as well as poor understanding of the costs they may incur. This makes them vulnerable to experiencing financial toxicity postoperatively and emphasizes the importance of understanding all contributing factors when developing future strategies to intervene in financial toxicity.
