Dear Bill, I am not sure what kind of further data you have, but if you like to visualize/detect changing groups of objects (patients) over time the work of Tanja Falkowski might be of interest for you:
http://omen.cs.uni-magdeburg.de/itikmd/Tanja_Falkowski.64.0.html there are some papers available on her website e.g. http://wwwiti.cs.uni-magdeburg.de/~tfalkows/publ/2007/KI_FalSpi07.pdf The algorithms she proposed try to detect and visualize groups that change over time in network like structures. You might get a network structure from your data by defining links based on similarity scores between patients (e.g. over a subset of treatment or - possibly more adequate here - data from patients records).
