연구의 필요성2010년) administration in either the inpatient (N = 70) or outpatient setting (N = 70) from January to July 2012 were included. In the outpatient setting, HD-MTX was administered intravenously (IV) over 6 hours and included hydration with sodium bicarbonate (2000 ml/m 2 / for 12 hours). Daily visits to the outpatient setting followed. Leucovorin was given 24 hours after MTX at a standard dose (15 mg/m 2 IV bolus) every 6 hours. We compared the serum drug levels of MTX, hematologic and renal toxicity, hepatotoxicity, frequency of subsequent unscheduled outpatient visits and readmission episodes, medical expenses and duration of hospital stay between the two groups. Results: HD-MTX administrations were successfully completed in both groups. No significant differences were found between the two groups for the parameters studied. Patients who received HD-MTX in the inpatient setting had 2.37 times and 2.24 times greater medical expenses and duration of hospital stay respectively than outpatient recipients. Conclusion: This study suggests that HD-MTX administration done with aggressive monitoring in the outpatient setting is safe and efficient, without a greater incidence of major toxicities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
