Incidence and resistance rates of Pseudomonas aeruginosa bloodstream infections in Switzerland: a nationwide surveillance study (2010-2022).
Observational study in Infection, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
purposeBloodstream infections (BSIs) cause significant morbidity and mortality worldwide. Pseudomonas aeruginosa is an important microorganism in BSIs. The aim of this study was to analyze recent trends in the incidence and resistance rates of P. aeruginosa BSIs in Switzerland and its different linguistic regions.
methodsThis retrospective, nationwide observational study analyzed the incidence (using Poisson regression models) and antimicrobial resistance (using logistic regression models) of P. aeruginosa BSIs in Switzerland from 2010 to 2022.
resultsThe annual incidence of P. aeruginosa BSIs in Switzerland increased from 5.5 BSIs per 100,000 inhabitants in 2010 to 7.6 BSIs per 100,000 inhabitants in 2022 (p < 0.001). The incidence was higher in the French-speaking region than in the German-speaking region. The resistance rates increased significantly for cefepime (2.4% in 2010, 8.8% in 2022; p < 0.001), ceftazidime (5.6% in 2010, 9.4% in 2022; p = 0.014), ciprofloxacin (3.3% in 2010, 6.5% in 2022; p = 0.014), and piperacillin-tazobactam (6.4% in 2010, 11.2% in 2022; p = 0.002). No significant trends were observed for carbapenem-, aminoglycoside-, or multidrug-resistant P. aeruginosa. A high incidence was observed in patients ≥ 80 years, whereas resistance rates were high in young patients.
conclusionThe increase in the incidence of P. aeruginosa BSIs emphasizes the importance of monitoring resistant and susceptible P. aeruginosa BSIs. Compared to the population-weighted mean resistance rates in Europe in 2022, those in Switzerland were lower, but an increase was observed for most antibiotics. The high resistance rates in young patients require further investigation.
