Financial toxicity in patients with glioblastoma.

Purpose: There has been mounting interest in understanding the impact of financial toxicity (FT) in various cancer types; however, it remains poorly understood and understudied within neuro-oncology-especially as it relates to neurosurgical components of patient care.

Methods: Retrospective, single-center study of patients who underwent craniotomy for resection of glioblastoma from 2020 to 2022. OIBEE™ (Austin, Texas) software was queried to identify the subset of these patients who had a bad debt charged to their account. These patients were deemed to qualify as experiencing FT. Chi Square analysis was conducted between FT and non-FT patient groups. Additionally, survival analyses were performed to determine predictors of progression free and overall survival.

Results: 74 patients were included in this sample. 33/74 (44%) met criteria for FT. The average bad debt amount was $7,476.76 and the median debt amount was $2,015.96, with the average time to financial toxicity after surgery being approximately 127 days. FT patients were significantly younger at diagnosis than those who were not FT (64.6 years- non-FT vs. 59.0 years- FT, p = 0.0344). FT patients were more likely to have undergone subtotal resections rather than a gross total resection compared to non-FT patients (FT GTR 27.3%, non-FT GTR 52.4%, p = 0.028). Hospital length of stay was significantly longer for FT patients compared to non-FT patients (LOS FT 9.5 days, non-FT 6.5 days, p = 0.0312).

Conclusion: Glioblastoma patients are at high risk of experiencing FT with our series showing no significant impact on overall survival. Larger studies are needed to understand the impact of FT on patient outcomes.
