Resource Utilization and Safety of Outpatient Management Following Intensive Induction or Salvage Chemotherapy for Acute Myeloid Leukemia or Myelodysplastic Syndrome

Resource Utilization and Safety of Outpatient Management Following Intensive Induction or Salvage... ImportanceAdults with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) typically remain hospitalized after induction or salvage chemotherapy until blood cell count recovery, with resulting prolonged inpatient stays being a primary driver of health care costs. Pilot studies suggest that outpatient management following chemotherapy might be safe and could reduce costs for these patients. ObjectiveTo compare safety, resource utilization, infections, and costs between adults discharged early following AML or MDS induction or salvage chemotherapy and inpatient controls. DesignNonrandomized, phase 2, single-center study conducted at the University of Washington Medical Center. Over a 43-month period (January 1, 2011, through July 31, 2014), 178 adults receiving intensive AML or MDS chemotherapy were enrolled. After completion of chemotherapy, 107 patients met predesignated medical and logistical criteria for early discharge, while 29 met medical criteria only and served as inpatient controls. InterventionsEarly-discharge patients were released from the hospital at the completion of chemotherapy, and supportive care was provided in the outpatient setting until blood cell count recovery (median, 21 days; range, 2-45 days). Controls received inpatient supportive care (median, 16 days; range, 3-42 days). Main Outcomes and MeasuresWe analyzed differences in early mortality, resource utilization including intensive care unit (ICU) days, transfusions per study day, and use of intravenous (IV) antibiotics per study day), numbers of infections, and total and inpatient charges per study day among early-discharge patients vs controls. ResultsFour of the 107 early-discharge patients and none of the 29 control patients died within 30 days of enrollment (P = .58). Nine early-discharge patients (8%) but no controls required ICU-level care (P = .20). No differences were noted in the median daily number of transfused red blood cell units (0.27 vs 0.29; P = .55) or number of transfused platelet units (0.26 vs 0.29; P = .31). Early-discharge patients had more positive blood cultures (37 [35%] vs 4 [14%]; P = .04) but required fewer IV antibiotic days per study day (0.48 vs 0.71; P = .01). Overall, daily charges among early-discharge patients were significantly lower than for inpatients (median, $3840 vs $5852; P < .001) despite increased charges per inpatient day when readmitted (median, $7405 vs $5852; P < .001). Conclusions and RelevanceEarly discharge following intensive AML or MDS chemotherapy can reduce costs and use of IV antibiotics, but attention should be paid to complications that may occur in the outpatient setting. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png JAMA Oncology American Medical Association

Pilot studies suggest that outpatient management following chemotherapy might be safe and could reduce costs for these patients.
