Health Care-Associated Infections in U.S. Hospitals, 2023 versus 2015.
Article in The New England journal of medicine, 2026. 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
backgroundPrevalence surveys in U.S. hospitals showed that on any given day, 1 of 25 patients had a health care-associated infection in 2011, as compared with 1 of 31 patients in 2015. We repeated the survey in 2023 to assess changes in the prevalence of such infections.
methodsUsing established methods, 10 Emerging Infections Program (EIP) sites recruited up to 25 hospitals each. Hospitals selected a survey day between May 1 and September 30, 2023. EIP staff reviewed medical records of randomly selected patients to identify health care-associated infections using National Healthcare Safety Network definitions. We described patient and hospital characteristics, compared the prevalence of health care-associated infections in 2023 and 2015, and estimated the national burden of health care-associated infections in 2023.
resultsIn 2023, of 13,653 patients in 218 hospitals, 355 (2.6%; 95% confidence interval [CI], 2.3 to 2.9) had at least one health care-associated infection, as compared with 394 of 12,299 patients (3.2%; 95% CI, 2.9 to 3.5) in 199 hospitals in 2015. Approximately 60% of the health care-associated infections were not associated with devices or procedures. Among 151 hospitals in both surveys, patients were less likely to have a health care-associated infection in 2023 than in 2015, after adjustment for other factors (risk ratio, 0.73; 95% CI, 0.63 to 0.85). We estimated that there were 518,000 health care-associated infections (95% CI, 494,500 to 542,000) in U.S. hospitals in 2023.
conclusionsThe prevalence of health care-associated infections was lower in 2023 than in 2015, with 1 of 38 patients on any given day having such an infection; however, the burden of health care-associated infections in U.S. hospitals continued to be high. A majority of the health care-associated infections that were identified were not associated with a device or procedure.
