To implement DTAS at a new facility, a large organizational effort is necessary. We performed a cost-utility analysis and budget impact analysis (BIA) of the operation of a new angiosuite, primarily dedicated to stroke patients, that allows facilities to approximate the cost implications of utilizing a DTAS pathway. Methods Sixty-one patients who underwent endovascular treatment (EVT) following DTAS were matched for baseline variables to 117 patients who underwent a conventional imaging protocol at a hospital in Catalonia, Spain. An economic model, based on actual data from these patients, was developed to assess the short- and long-term clinical and economic implications of DTAS. In the BIA, the DTAS scenario was gradually implemented for 20% of patients each year until reaching a plateau at 80% of patients in the DTAS pathway. Initial investment and additional organizational costs, €4 million, were taken into consideration to compare the budget impact of the DTAS scenario with no organizational changes over five years. Results DTAS was associated with better patient functional independence rates (mRS 0–2: 50.9% vs. 41.0%) and a quality-adjusted life-years gain of 0.82 per patient. Despite the additional initial investment, DTAS development was associated with an estimated 10.2% reduction (€14.7 million) of the total costs (€144.5 million). Cost savings were mainly due to long-term associated costs related to patient disability (€13.2 million). Limitations The study relies on data obtained from a single-center, and therefore it may be difficult to generalize the findings Conclusions Our economic model predicts that the implementation of a DTAS program is cost-effective compared with no organizational changes. Our model also predicts better clinical outcomes for patients in terms of functional independence and quality-adjusted life years. This study was sponsored by Medtronic.

Background and purpose: Direct transfer to angiosuite (DTAS) has consistently shown to be effective and safe shortening in-hospital workflows and encouraging long-term outcome benefits. In order to generalize DTAS an organizational and manpower effort is necessary. We aim to perform a cost-effective analysis of the implementation of a new angiosuite primarily dedicated to DTAS of stroke patients that will allow generalization of this pathway Material and methods: Sixty-one patients who underwent endovascular treatment (EVT) following DTAS were matched for baseline variables to 117 patients who underwent conventional imaging protocol before EVT. An economic model based on actual data was developed to assess the short and long term clinical and economic implications. The DTAS development scenario estimates a gradual 20% increase of DTAS rate for 4 years followed by a stable 80% rate of DTAS. Initial investment and additional organizational costs were included: 4M є. A cost-effective study compared the DTAS development scenario (SC1) to a scenario with no organizational changes (SC2) over 10 years. Results: The 10 year model included 1775 EVT patients in each scenario: SC1 60% DTAS Vs SC2 0% DTAS. SC1 would be associated with better functional independence rates (mRS 0-2: 45.8% versus 40.2%; p=0.04) and a quality-adjusted life-years gain of 0.12 per patient. Despite the additional investment, SC1 development was associated with an estimated 15.1% reduction (26.25M є) of total costs (173.749M є). Cost savings was mainly due to long-term associated costs related with patient disability (є 26.4 million). Conclusions: Our economic model predicts that the development of a DTAS program is cost effective.
