@awrosen: Nothing wrong with Anna’s proposal, of course, but just keep in mind: Once we have the Episode table that’s where these things should live, NO MATTER if they are abstracted from the raw data or you are getting them directly.
Anna’s proposal has two disadvantages: First, as I said before, it is not interoperable, and second, you will have a hard time defining the domains. And even when you define the domains they will be different, resulting in your scores in different tables: Conditions (e.g. “multi organ dysfunction”, Observations (e.g. “any deviation from the normal postoperative course”), Drugs (e.g. “antiemetics, antipyretics, analgetics, diuretics and electrolytes”) or Procedures (e.g. “surgical, endoscopic or radiological intervention”). You could make them all Observations and call them “Grade I Clavien-Dindo Score” etc., but then you would miss the fact that these indicate clinical events. Ugly one way or another.
