Figure 1.

Patient states and state transition rates Squares depict possible states with respect to CRE in the compartmental model. Arrows between squares depict possible state transitions during the LTACH stay and are labeled with rate parameters; arrows into squares from outside point to possible states at admission and are labeled with probabilities of each admission state. Patients in any state can be removed via death or live discharge (not depicted)—see Supplementary material for full mathematical specification.
