Polymedikation by bjuhre

Dieses Modell wurde im Rahmen eines Workshops im Modeler-Forum Berlin-Brandenburg erstellt. Es soll die Zusammenhänge verdeutlichen, mit denen das Problem der Polymedikation (d.h. Patienten, die diverse verschiedene Arzneimittel (AM) einnehmen) verbunden ist. Das Modell ist sicherlich nur ein erster Ansatz zu diesem Thema und kann gerne noch weiter vertieft werden.
