FWIW I'd definitely put 'out of danger think about releasing from hospital' at 0 hp+ not -1xHP.

Not just because at negative HP the risks of anything going wrong are bad (but that is reason enough), but to be bloody minded about it the benefit of freeing up a bed would have to weighed against the risk of a law suit based around 'you released the patient to early' if something did go wrong. Obviously in some contents and setting this might not be so much of an issue!

Ideally for both patient and medical resources they would be moved to low intensity convalescence ward.
