Background: The Oncology Care Model (OCM) is intended to incentivize physicians to improve the quality and reduce the cost of cancer care. In OCM, providers are accountable for all costs during six month episodes of care relative to target costs (TC) derived from a baseline spending period (BSP; 2013-2015). This accountability is intended to foster care coordination to reduce preventable emergency department visits and hospitalizations (EDH). Benefits of reducing EDH may be diluted when new treatment indications for costly immunotherapies (IO) are introduced into clinical practice after BSP.
Methods: We identified all non-small cell lung cancer (NSCLC) and bladder cancer (BC) OCM episodes attributed to Tennessee Oncology (TO), a large community oncology network of over 90 oncologists, during performance period 2 (PP2; the most recent PP with available data). We selected NSCLC and BC because both diseases have IO indications that became standard of care after BSP. Using claims data analytics software, we identified all NSCLC and BC episodes with spending above TC, and found a subset of these above target episodes (ATEs) without any EDH that remained above TC due to IO use. Two medical oncologists reviewed these cases in duplicate to assess guideline concordance of IO.
Results: During PP2 there were 2,623 OCM episodes attributed to TO, including 240 NSCLC and 31 BC episodes. Spending was above TC in 118 (49%) and 13 (42%) of NSCLC and BC episodes, respectively. For these NSCLC and BC ATEs, EDH was prevented in 62 (53%) and 5 (38%) of cases, respectively. In NSCLC and BC ATEs without EDH, 43 (69%) and 5 (100%) of episodes included IO, respectively. Clinician review in duplicate (S.M.S.; C.A.W.) found that the use of IO was NCCN guideline concordant in 33 (77%) and 4 (80%) of these NSCLC and BC cases, respectively (K = 0.87).
Conclusions: Guideline-concordant use of expensive IO as its treatment indications expand poses substantial challenges to meeting cost targets in OCM, even when practices prevent EDH.
