Objectives: New and emerging therapies have significantly changed the bladder cancer (BC) treatment landscape and can potentially affect spending and patient care in CMS' Oncology Care Model (OCM), a service delivery and payment model for voluntarily participating practices. The objectives of this analysis were to estimate health care resource utilization (HCRU) and benchmark spending per OCM episode of BC, and to model spending drivers and quality metrics.
Study design: Retrospective cohort study.
Methods: A retrospective cohort study was conducted of OCM episodes triggered by receipt of anticancer therapy among Medicare beneficiaries from 2016 to 2018. Based on this, an average performance estimation was conducted to assess the impact of hypothetical changes in novel therapy use by OCM practices.
Results: BC accounted for approximately 3% (n = 60,099) of identified OCM episodes. Relative to low-risk episodes, high-risk episodes were associated with greater HCRU and worse OCM quality metrics. Mean spending per high-risk episode was $37,857 (low-risk episode: $9204), with $11,051 spent on systemic therapies and $7158 on inpatient services. In the estimation, high- and low-risk BC exceeded the spending target by 1.7% and 9.4%, respectively. This did not affect payments to practices and no retrospective payments were necessary.
Conclusions: As 3% of OCM episodes were attributed to BC, with only one-third classified as high-risk, controlling expenditure on novel therapies for advanced BC is unlikely to affect overall practice performance. The average performance estimation further emphasized the minimal impact that novel therapy spending in high-risk BC has on OCM payments to practices.
