The feasibility of antimicrobial lead time as process and quality indicator for hospitals.
Article in European journal of clinical microbiology & infectious diseases : official publication of the European Society of Clinical Microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeAntimicrobial lead time (ALT) is the time from antimicrobial order to administration, an understudied parameter. This study aims to determine feasibility of retrieving ALT, differences in ALT for different infectious diseases and the association of ALT with length of stay (LoS) in order to establish the value of this parameter as potential new process or quality indicator (QI).
methodsIn a retrospective study in a tertiary care hospital in the Netherlands, adult hospitalized patients treated for an infection were included over a 20-month period. ALT was calculated with data from the electronic health record system with computerized provider order entry.
resultsThousand patients (56.1% men, median age 61 years) were included. The median ALT was 1.05 h and significantly shorter in septic patients (n = 65) than in patients with other infections (n = 935; 0.27 h, interquartile range (IQR) 0.07-0.67 vs. 1.18 h, IQR 0.37-3.15; p < 0.001). If blood cultures were obtained median ALT was shorter (0.85 h vs. 1.77 h; p < 0.001). ALT was not shorter in patients with positive compared to negative blood cultures (0.63 h vs. 0.94 h; p = 0.053). Antimicrobials ordered in the emergency room had a shorter median ALT than in medical wards (0.43 h vs. 1.57 h; p < 0.001). After correcting for indication, we found no association between ALT and LoS (p = 0.34).
conclusionsALT is an easily measurable QI for sepsis. More studies are needed to establish whether ALT is a feasible QI for meningitis and community-acquired pneumonia. For all infections, ALT can be used as process indicator for drug administration.
