Abstract 3138: Hospitalization Costs for Acute Ischemic Stroke Patients Treated with Endovascular Embolectomy in the United States
Background and Purpose- It is important to know the costs for hospitalization for endovascular embolectomy patients so that comparisons can be made to payments to hospitals.
Methods- Using the National Inpatient Sample, we evaluated the costs for hospitalization for patients treated with endovascular embolectomy in the United States from 2006-2008. The primary endpoint examined in this study was total hospital costs, and these were correlated with clinical outcome. Hospitalization costs were then compared with Medicare payments for their respective outcomes. MS-DRG 24 was the diagnostic related group code (DRG) for mechanical embolectomy with good outcome and MS-DRG 23 was the DRG code for mechanical embolectomy with major complications. Medicare payments were available at http://www.cms.hhs.gov.
Results- A total of 3864 patients received endovascular embolectomy. 1649 patients were <65 years old and 2205 patients were ≥65 years old. Median hospital costs in 2008 dollars were $36,999 (IQR $26,662-$56,405) for patients with good outcome, $50,628 (IQR $33,135-$76,063) for patients with severe disability, and $35,109 (IQR $25,053-$62,621) for patients with mortality. Reimbursement in the year 2008 for DRG 24 (good outcome) was $22075 and reimbursement for DRG 23 (major complications) was $26639.
Conclusions- Our study of the NIS shows that hospitalization costs in the United States for ischemic stroke patients treated with endovascular embolectomy are rather high, probably due to the serious nature of their illness. Medicare payments have not been adequate in reimbursing these hospitalizations. Further work is needed to ensure the future reconciliation of costs with payments.
