Computer Algorithms To Detect Bloodstream Infections
|Determination||Method||No. culturesc||Sensitivity (%)||Specificity (%)||κ|
|Hospital vs. community acquisition||Computer rule A||77||97||73||0.74|
|Infection vs. contaminationd||Computer rule B2e||43||77||71||0.49|
|Primary vs. secondary||Computer rule C2f||76||90||57||0.49|
aOur reference standard.
bThe single best rule for each determination is displayed.
cSince all determinations were not made for each blood culture, e.g., contaminants often were not further categorized, the number of cultures evaluated varies.
dInfection determination is presented for common skin commensals only; other organisms were considered as infections; see Table 1 for definitions.
eRule B2 evaluated microbiology and pharmacy results; see Table 1.
fRule C2 evaluated microbiology results during the entire length of stay; see Table 1.
