Direct hospital resource utilization and costs of treating patients with multiple myeloma in Southwest Sweden: a 5-year retrospective analysis.
BACKGROUND
Approximately 570 patients are diagnosed with multiple myeloma (MM) in Sweden each year. Few studies have estimated the cost of treatment for these patients.


OBJECTIVE
The purpose of this study was to retrospectively investigate the direct hospital resource utilization and costs associated with the treatment of patients with MM in southwest Sweden.


METHODS
Patients aged > or =18 years who initiated first-line chemotherapy in the year 2001 at hospitals in southwestern Sweden were included in this retrospective chart review. Direct hospital-based resources and their corresponding costs (year-2006 euros) for each patient were calculated until the patient's death, or until December 31, 2005. Costs for outpatient and terminal stage care related to MM were not included.


RESULTS
Ninety-four patients were included; 20 were still alive at study completion. Mean age at diagnosis was 76 years and patients were followed for a mean of 32.7 months; 55% were males and 74% had at least 1 comorbidity. First-, second-, and third-line treatment lasted a mean of 24.3, 5.8, and 2.6 months, and included 2.8, 2.6, and 3.1 chemotherapy drugs per patient, respectively. Of the 80 patients who received first-line chemotherapy, 72 were prescribed melphalan and 55 patients received a combination of melphalan and prednisone, as recommended by Swedish treatment guidelines. The mean total cost per patient was euro88,199, or euro2770 per patient-month. Therapy-induced and comorbidity-related events constituted 42% of total costs, as much as autologous stem-cell transplantation and inpatient care together. Chemotherapy, bisphosphonate, and blood cell-enhancement drugs each amounted to only 2% of total costs, but chemotherapy drugs increased from euro29/month in first-line therapy to euro453/month in third-line therapy.


CONCLUSIONS
The cost of treating Swedish patients with MM varied greatly between individuals but, overall, chemotherapy drugs constituted only a minor part of the total monthly cost (2%), whereas costs for inpatient stays and therapy-induced adverse events or comorbidity-related events accounted for 35% and42%, respectively. There was no significant differencein monthly cost between treatment lines.
