Table 1.

Time from model prediction to clinical suspicion of infection.

Δtlactate (in hours) Δtsuspicion (in hours) ΔtABX (in hours) Δtculture (in hours)
Hospital-A Temporal ICU
 COMPOSER 2 [0 7] 8.4 [1.2 11.5] 12.2 [3.2 22.8] 11.2 [5.2 11.9]
 ESPM (score>5) 1 [0 5] 3.5 [0.2 11.2] 10.2 [1.0 18.9] 8.9 [1.2 11.9]
Hospital-A Temporal ED
 COMPOSER 1 [1 2] 1.0 [0.3 2.3] 2.1 [0.8 4.5] 0.8 [0.2 3.4]
 ESPM (score>5) 0 [−1 1] 0.1 [−0.9 0.65] 0.6 [0.2 2.0] 0.2 [−0.8 1.0]

The difference between the time at which an alarm (talarm) was fired (i.e., risk score exceeded a decision threshold) and tlactate /tsuspicion/tABX/tculture for the Hospital-A Temporal ICU and ED cohorts are shown. talarm corresponded to the earliest time at which an alarm was fired in the interval [tsuspicion˗ 12 h, tsuspicion+ 12 h]. tlactate corresponded to the earliest time at which a lactate measurement was made in the interval [tsuspicion˗ 12 h, tsuspicion+ 12 h]. tABX corresponded to the time at which antibiotics were ordered following tsuspicion. tculture corresponded to the time at which cultures were ordered following tsuspicion. A negative value indicates the alarm was fired after the time point of interest.
