Incidence of postoperative fever and bloodstream infections in gynecological surgical patients: a three-year retrospective surveillance.

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
backgroundPostoperative bloodstream infection (PBSI) is a severe complication in gynecological surgery, associated with higher morbidity than surgical site infections. However, large-scale data on PBSI epidemiology and risk factors, particularly from the Chinese population and within modern Enhanced Recovery After Surgery (ERAS) pathways, are scarce. This study aimed to define the incidence, etiology, and modifiable risk factors for PBSI in a major Chinese tertiary center.
methodsWe conducted a three-year (Jan 2022–Dec 2024) retrospective cohort study of 19,906 patients undergoing gynecological surgery. Data were extracted from electronic medical records to determine the incidence of postoperative fever (PF) and PBSI. Pathogen distribution, antimicrobial susceptibility, and risk factors were analyzed using univariable and multivariable logistic regression models.
resultsThe overall incidence of PF was 2.67% and PBSI was 1.30%. The institutional rate of preoperative vaginal preparation was strongly and inversely correlated with PBSI incidence (ρ = -0.50, P = 0.002). Multivariable analysis identified several independent risk factors, including combined high-risk surgery (aOR 3.72; 95% CI, 2.84–4.89), and seasonality, with peak risk in Q3 (aOR 2.03; 95% CI, 1.41–2.96). Escherichia coli was the predominant pathogen in culture-positive PBSI (70.37%), exhibiting high resistance to the first- and second-generation cephalosporins commonly used for prophylaxis, but remained susceptible to carbapenems and β-lactam/β-lactamase inhibitors.
conclusionsThe implementation of preoperative vaginal preparation as a core component of a quality improvement initiative was associated with a lower institutional PBSI rate. The high prevalence of resistant E. coli likely neutralizes the effectiveness of standard antibiotic prophylaxis, mandating a shift towards antibiotic stewardship guided by local antibiograms. Risk stratification should also account for surgical complexity and seasonal peaks. These findings provide a data-driven framework for optimizing infection prevention strategies in modern gynecological surgery. CLINICAL TRIAL REGISTRATION NUMBER: Not applicable.
