Healthcare resource utilization and costs of adverse events among patients with metastatic urothelial cancer in USA.

Abstract

Aim: To estimate incremental costs and healthcare resource utilization (HRU) associated with select severe adverse events (AEs) and AEs of any severity in patients with metastatic urothelial carcinoma receiving first-line (1L) therapy. Materials & methods: Adults treated with 1L systemic therapy between January 2012 and September 2017 with ≥1 urothelial cancer diagnosis were identified using claims data. Per-patient-per-month cost differences and HRU rate ratios comparing patients with and without select AEs were estimated. Results: Patients with any severe select AEs had higher costs than those without (cost difference\xa0=\xa0$6130 per-patient-per-month; p\xa0<\xa00.001). Healthcare costs and HRU for patients with select AEs were significantly higher versus those without. Conclusion: Select AEs during 1L therapy for metastatic urothelial carcinoma can result in significant burden to patients and healthcare systems.
