When he said hospital, I assumed he meant "mental institution".

Todoriki is Endeavor's best chance of realizing his goal, and his mother basically went nuts and attacked him. He basically used his influence to have her indefinitely committed.

He probably didn't even have to try that hard. Having a breakdown and pouring scalding water on your child is probably a pretty reasonable reason to be committed.
