Critical Care Patients/Game in a game idea

As a possible idea for late-game play. this would envision a special class of critical care patients. These could be a special type of patient (to include trauma but not solely trauma victims) that arrive at the hospital with a designation (this could be optional) and present with much greater degree of diagnostic challenge. Their diagnoses would require more advanced and expensive equipment, and all this would be coupled with a very definite and truncated (although unknown to the player) time frame in which the patient can successfully be treated before they expire.

it would only enhance such a feature if many of these patients were experiencing issues that require more than one treatment/diagnosis.
