The main concept of my thesis is to group patients of constant treatment complexity. I have a returning idea of creating atomic groups, a base granularity. Atomic groups would be the smallest units of the grouping process.
Atomic groups would be defined by a set of procedures, probably one or two. Every atomic groups should have some minimal size, let's say, about 50 patients.
Each atom could carry a regression-based model, explaining additional effects inside the atom. Especially, influence of the weight on the mortality. Each patient would carry the source atom signature and the predicted (according to the atom's model) mortality.
- Find popular pairs of procedures
- Find single popular procedures
- Create a list of rules that assign patients to atomic groups
- Following operations would be performed against the atoms
