All indicator stabilization sequences with five or more occurrences among the 1,326 patients in the sample are shown. These 21 of 986 unique patterns accounted for 197 patients (14.86 % of sample). The “Stable at Admission” column in the table shows the indicators that were already stable at admission. The stabilized “1st” column shows the indicators that were stabilized at the same, first, observation point during the hospitalization before discharge, and, if any, the indicators that remained unstable before discharge (lowercase and →). The following three columns show the indicators stabilized second, third, or fourth before discharge, along with indicators, if any, that remained unstable. The last two columns show how many (n, %) patients in the sample had each respective instability resolution pattern. For example, for pattern 15, six patients presented with BP, MS, and RR already stable, OI and O2 indicators were later observed to stabilize together, T was next observed to stabilize by itself, and these patients were discharged before HR could be stabilized.
