A question about treatment

So, i have a question about treatment.

When i control sometimes patients i realise, that doctors and nurses in wards dont treat ALL symptoms. So this can cause collapses if i dont play myself as doctor.

The other thing is why do they more diagnosis on illness that dont require hospitalisation? Most time they send them to labor or smth but they already HAVE a diagnosis that could be treated and send home.

If i dont pay attention to all my patients, that was happens offen.
Is there something i miss in there?

If you have certainty set to 100%, they will continue to run tests until they run out of procedures or all symptoms are found.

No, they don't treat all symptoms. They will, however, treat symptoms that can cause collapses, so if you're getting collapses, then something isn't treated or wasn't treated fast enough.
