Barriers to patient-centered oncology care: Pilot study of home infusion of anticancer immunotherapy.

Abstract

36 Background: ASCO published a position statement regarding home infusion of anticancer therapy in June 2020. This statement recommends independent research to evaluate the safety and effectiveness of home infusions. Intermountain Healthcare (IM) incorporated this statement into its oncology care with an IRB-approved, prospective single-arm pilot study to determine the safety and feasibility of home administration of checkpoint inhibitor (CPI) immunotherapy with synchronous telemedicine visits. Methods: Patients with cancer receiving treatment at Intermountain Medical Center and Intermountain Cancer Center St. George were screened for enrollment into an IRB-approved, non-randomized pilot study of 20 patients. Eligibility criteria required patients to receive a CPI for an FDA-approved indication, live in Washington County or Salt Lake County, Utah, and have commercial payer coverage of CPI home infusion. Eligible patients were required to receive 2 doses of CPI at an infusion center, and patients who experienced an infusion reaction were excluded from receiving home infusion. Home infusion nurses are trained in oncology, CPIs, and home infusion reaction protocol. During synchronous video visits, infusion nurses are trained to perform the hands-on portions of the physical exam. A financial analysis estimated cost to IM and commercial payers for routine and home CPI infusions. Results: 622 patients were screened, of which 104 were receiving a CPI. 64 patients lived in an eligible county and 19 patients had commercial payer coverage. Of patients on CPIs, 8.7% (9/104) met all eligibility criteria accounting for 1.4% (9/622) of all patients with cancer screened (Table). Financial analysis estimated $829 cost (excluding drug cost) to IM for standard infusion reimbursement compared to $599 for in-home CPI infusions, accounting for savings of $230 per infusion. Majority of cost savings are from elimination of infusion center facilities fee ($495). Analysis includes $269 for home infusion nurse wages. Subsequent analysis for commercial payer SelectHealth estimates $270 reimbursement savings for the payer. Conclusions: Home immunotherapy infusions are estimated to be cost effective for both IM and commercial payers. However, lack of drug coverage and the rural demographics of Utahns with cancer are barriers to home CPI infusions. The pilot study was discontinued per infeasibility stopping criteria.[Table: see text]
