| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Procalcitonin (PCT) Group | Provide PCT results and procalcitonin guideline to treating clinician; Telephone Visit at Day 15 and Day 30 for # of ABX days~A procalcitonin (PCT) will be drawn within one hour after randomization in the ED, and if hospitalized, 6-24 hours after the initial ED blood draw, and on Days 3, 5, and 7. Days 3, 5, and 7 blood draws for procalcitonin will only occur in hospitalized patients on antibiotics and/or at the treating physician's discretion.
