Lab Collection Process

Note: See Labs?? for more general info on the labs data.

The Critical Care database counts the laboratory tests listed at S AllLabsTable for every patient for their entire LOS in a unit.

HSC Data Collectors only count a "subset" of S ALLlabsTable because some of the lab test are dwonlaoded and imported directly in master TMSX Database.

Lab Collection Process

• For every ICU patient,
  • for every qualifying laboratory test
    • locate the specific lab, enter the number of times the test was performed
    • if a culture is taken but the sample was inadequate to produce a result, the culture is still counted under lab counts
    • for platelets, one bag hung as indicated on the TISS is equal to 5 platelet units in the lab count.
  • if a patient has no labs by the end of their stay, enter a date and leave zeros under all the labs
