Estimation of economic costs associated with transfusion dependence in adults with MDS
2009
ABSTRACTObjective: To examine the economic burden of myelodysplastic syndromes (MDS) and the incremental cost of transfusion dependence.Research design and methods: Adults with evidence of MDS were identified between 05/01/2000 and 09/30/2003 from a longitudinal, retrospective claims database for a large, geographically diverse US health plan and their medical histories were followed for at least 6 months. Patients were classified as transfusion-dependent (MDS-TD) or transfusion-independent (MDS-TI).Main outcome measures: Variables were categorized as demographic, health status, utilization, or cost. Utilization (inpatient hospitalizations, outpatient facility visits, emergency department visits, and physician office visits) is reported as the mean and median numbers of each specified encounter per subject. Costs were measured as the sum of patient and plan liability. All variables were analyzed descriptively, and appropriate statistical tests were used to compare the MDS-TD and MDS-TI cohorts.
