Patient Scoring Systems

How do we score the status of a patient? Well, we can begin by having a chart—SpO2, can breath, etc. etc.


  1. these systems are quite generic
  2. not very representative of some information


  1. MIMIC-IV 6000 ICU patient stays, 48994 vital signs—measuring across patient stays
  2. dynamic time warping to create a similar matrix
  3. clustering post-hoc to correlate patients together
