Definition of observation sets. We illustrate here a simplified version of how we defined observation sets using 3 vital signs only: heart rate (HR), respiratory rate (RR), and systolic blood pressure (SBP). Vital signs taken at the same time were grouped together for the same patient encounter into observation sets. We subsequently applied our inclusion and exclusion criteria to select the relevant patient encounters and associated observation sets.
