Purpose: The purpose of the Oncology Care Model (OCM) is to improve quality and reduce cost through practice transformation. A foundational tenant is to reduce avoidable emergency room (ER) visits and hospitalizations. In anticipation of being an OCM participant, we instituted a multidimensional campaign designed to meet these objectives. Methods: Prior actions included establishment of phone triage unit, after-hours and weekend calls, and institution of weekend urgent care. Results: On the basis of data from the Chronic Condition Warehouse, as provided by the Centers for Medicare and Medicaid Services, we were successful at reducing the acute care admissions rate by 16%. During the baseline period extending from Jan 2016-Mar 2016, the hospital admission rate was 27 per patient, per quarter, at an average cost per admission event of $11,122, translating to an inpatient cost per patient, per quarter, of $3,003. In the year one reporting period of July 2016-July 2017, the hospital admission rate declined to 22.6 per patient, per quarter, at an average cost per admission event of $11,106, translating to an inpatient cost per patient, per quarter, of $2,505. OCM patient survey scores improved. In addition, at Oncology Hematology Care, we achieved improved results compared with the risk-adjusted national averages for the following measures: readmissions (4.9 v 5.6 per 100 patients, respectively), ER use (17 v 18.6 per 100 patients, respectively), and observation stays (2.7 v 3.6 per 100 patients, respectively). Conclusion: By implementing a cost-efficient, reproducible, and scalable campaign targeting ER avoidance and hospitalizations, we were able to decrease hospital admissions. Reported Medicare savings amounted to nearly $798,000 in inpatient cost per quarter over 1,600 patients.
