This study looks at how hospitals can better handle stroke emergencies. A stroke is when blood flow to the brain is blocked or a blood vessel bursts. The study focuses on the "Door-In-Door-Out" (DIDO) process, which is the time it takes for a patient to arrive at a hospital, be evaluated, and then transferred if needed. Quick transfers are crucial because some hospitals can't provide the advanced care required. The study aims to improve this process in eight different regions across the U.S. to help patients get the care they need faster.

• The study involves hospitals across the U.S. and tests new methods for faster patient transfers.
• Participants must be 18 or older and have certain types of strokes, like AIS or ICH.
• People in other stroke trials or those under comfort care on the first days can't join.

This study is important as it can improve how hospitals handle strokes, potentially saving lives and reducing disabilities.
