Hope is all those parents have going for them.

This is a line taken from House MD, season 3,episode 4.

“Wilson: Hope is all those parents have going for them.”

What does it exactly mean?

Thanks.

That the only thing the patients have left is ‘hope’ (that they will improve, be cured, not be in pain, etc.).

but it is little bit comlicatted because (going)here refers to hope is all and have nothing to do with (have)
may be gramatically well organised to say
hope is all going for those parents
if i am mistaken ,help me
because my old informations may need to be well revised

to ‘have something going for’ you/somebody is an idiomatic expression.
