Abstract

CONTEXT: In previous smaller trials, a procalcitonin (PCT) algorithm reduced antibiotic use in patients with lower respiratory tract infections (LRTIs). OBJECTIVE: To examine whether a PCT algorithm can reduce antibiotic exposure without increasing the risk for serious adverse outcomes. DESIGN, SETTING, AND PATIENTS: A multicenter, noninferiority, randomized controlled trial in emergency departments of 6 tertiary care hospitals in Switzerland with an open intervention of 1359 patients with mostly severe LRTIs randomized between October 2006 and March 2008. INTERVENTION: Patients were randomized to administration of antibiotics based on a PCT algorithm with predefined cutoff ranges for initiating or stopping antibiotics (PCT group) or according to standard guidelines (control group). Serum PCT was measured locally in each hospital and instructions were Web-based. MAIN OUTCOME MEASURES: Noninferiority of the composite adverse outcomes of death, intensive care unit admission, disease-specific complications, or recurrent infection requiring antibiotic treatment within 30 days, with a predefined noninferiority boundary of 7.5%; and antibiotic exposure and adverse effects from antibiotics. RESULTS: The rate of overall adverse outcomes was similar in the PCT and control groups (15.4% [n = 103] vs 18.9% [n = 130]; difference, -3.5%; 95% CI, -7.6% to 0.4%). The mean duration of antibiotics exposure in the PCT vs control groups was lower in all patients (5.7 vs 8.7 days; relative change, -34.8%; 95% CI, -40.3% to -28.7%) and in the subgroups of patients with community-acquired pneumonia (n = 925, 7.2 vs 10.7 days; -32.4%; 95% CI, -37.6% to -26.9%), exacerbation of chronic obstructive pulmonary disease (n = 228, 2.5 vs 5.1 days; -50.4%; 95% CI, -64.0% to -34.0%), and acute bronchitis (n = 151, 1.0 vs 2.8 days; -65.0%; 95% CI, -84.7% to -37.5%). Antibiotic-associated adverse effects were less frequent in the PCT group (19.8% [n = 133] vs 28.1% [n = 193]; difference, -8.2%; 95% CI, -12.7% to -3.7%). CONCLUSION: In patients with LRTIs, a strategy of PCT guidance compared with standard guidelines resulted in similar rates of adverse outcomes, as well as lower rates of antibiotic exposure and antibiotic-associated adverse effects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
