Question

Do both sentences mean the same thing?

1) Had he gone to a hospital sooner, more likely he might have survived.

2) Had he gone to a hospital sooner, he would more likely have survived.

Answer

Neither one is correct, I would suggest 
Had he gone to a hospital sooner he would/might have been more likely to survive
For me a hospital or the hospital  are both correct as it could be referring to any hospital or a specific hospital

Answer

The 2nd sentence is more correct but it should be "to the hospital" not to "to a hospital".
