Abstract
The Children's Oncology Group recommends children with high-risk acute lymphoblastic leukemia (ALL) receive high-dose methotrexate (HD MTX) throughout treatment. Historically, patients have been hospitalized for at least 54 hours for HD MTX. Literature supports the safety and efficacy of the transition of supportive care interventions of intravenous (IV) fluids and leucovorin to ambulatory care. The goal of this quality improvement (QI) project was to implement a system to support the safe delivery of supportive care in the home after inpatient HD MTX in children with high-risk ALL. An interdisciplinary team implemented system changes including an ambulatory supportive care protocol, standard computerized order sets, family education, and education of staff in the inpatient, outpatient, and home care setting. Measurements included laboratory results of renal function and medication clearance, length of hospitalization, and family-reported quality of life. During project implementation, 10 patients completed a total of 38 cycles. The system safely and effectively supported transition to the outpatient setting for all patients. Average length of stay was decreased by 37.8 hours per HD MTX cycle. Families reported that quality of life improved in most domains with family time and sleep having largest improvement, while level of stress remained the same. Ambulatory monitoring post-HD MTX requires a multidisciplinary approach to meet individualized patient needs. Future QI efforts should consider outpatient administration of HD MTX in addition to supportive care as a means to improved quality of life.
