Endovascular Stroke Therapy Trends From 2011 to 2017 Show Significant Improvement in Clinical and Economic Outcomes. Issue 7 (July 2019) - Rai, Ansaar T.
Abstract : Background and Purpose—: The purpose of this study was to evaluate trends in length of stay, discharge status, and costs among patients with acute ischemic stroke who underwent endovascular therapy (ET) between 2011 and 2017. Methods—: Using a retrospective observational study design, acute ischemic stroke patients undergoing ET from 2011 to 2017 were identified in the Premier Healthcare Database. The Mann-Kendall trend test was performed to examine clinical and economic outcomes trends. Results—: Among the 505 824 acute ischemic stroke patients, 11 811(2.3%) were treated with ET. Patients receiving ET had a significant increase in home discharge and a significant decrease in mortality (17.7% to 29.6%, P <0.01; 21.6% to 12.8%, P <0.01). There was a significant decline in length of stay from 11.7 days to 8.7 days ( P <0.01). Total index admission costs declined ≈17% from 2011 to 2017 ($50 516.5–$42 026.9, P <0.01). Conclusions—: Clinical and economic indicators significantly improved for acute ischemic stroke patients undergoing ET from 2011 to 2017.
