Pursuit of performance: An exploration of predictors associated with achieving performance based payments for breast cancer episodes under the Oncology Care Model.
e18035 Background: The Oncology Care Model (OCM) captures patient costs in a 6-month episode triggered by administration of systemic therapy. Most breast cancer (BC) patients will receive systemic therapy, with variations depending on stage and hormonal status, which makes BC an ideal indication to study costs in the OCM. Practices earn performance based payments (PBP) if aggregate episodic expenditures are managed below set target prices. We investigated predictors for episodic expenditures exceeding target prices, thus reducing potential for PBP. Methods: We identified BC episodes with non-decedent beneficiaries attributable to our academic medical center from OCM Reconciliation Reports during 7/1/16-6/30/17. Cohorts were defined as episodes whose costs were above target (Cohort 1) and those below (Cohort 2). The Wilcoxon Rank-Sum test was used to compare actual and target episode expenditure between cohorts. Multivariable logistic regression models were used to assess association of maintaining costs below target due to various predictors. Results: A total of 369 episodes were included in the study, with 124 episodes in Cohort 1 and 245 in Cohort 2. Median actual and target episode expenditures were higher in Cohort 1 (actual: $23,466 vs. $2,691, p < 0.0001; target: $8,425 vs. $5,870, p < 0.0001). In multivariable logistic regression, episodes were more likely to be below target if novel therapies, Part B drugs, or inpatient admissions were not utilized, controlling for other predictors (see Table). Conclusions: Large disparities exist for both actual expenditures and target prices for BC episodes in the OCM. Novel therapies, Part B drugs, and inpatient admissions are negatively associated with maintaining episode expenditures below target. Risk-adjustments for these expenditures need to be overhauled in OCM to accurately capture costs associated with management of cancer patients, and provide practical target prices for institutions to continue delivery of value based care.
