Introduction: Surgical site infection (SSI) surveillance is resource-intensive, particularly in low-resource settings. This study evaluated whether selective surveillance of high-risk patients can accurately identify postoperative SSI compared with traditional surveillance of all surgical patients. Methods: A cross-sectional study was conducted among 587 patients who underwent selected general surgical procedures from January 2022 to June 2023 in a tertiary university hospital. Patients were classified as high-risk or low-risk for SSI using eight perioperative variables. Logistic regression analysis identified factors independently associated with SSI. The accuracy and agreement of selective surveillance versus traditional surveillance were assessed using sensitivity, specificity, predictive values, and Cohen’s kappa. Results: The overall SSI rate was 12% (71/587). Independent predictors of SSI included resident service cases (OR 2.57, 95% CI 1.37–4.83), ASA score 3–5 (OR 6.28, 95% CI 3.30–11.93), clean-contaminated to dirty wounds (OR 21.73, 95% CI 6.26–75.48), operative duration beyond the 75th percentile (OR 2.33, 95% CI 1.24–4.38), and failure to maintain perioperative normothermia (OR 39.49, 95% CI 3.35–465.06). Selective surveillance demonstrated 100% sensitivity, specificity, positive predictive value, and negative predictive value, with perfect agreement with traditional surveillance (Cohen’s kappa = 1.00). Conclusion Selective surveillance focused on high-risk patients demonstrated excellent agreement with traditional surveillance and may serve as a cost-effective alternative for SSI monitoring in resource-limited settings.

Central line associated bloodstream infection (CLABSI) is the most severe complication of indwelling intravascular catheters and one of the most common causes of intensive care unit (ICU)- or hospital-acquired infections. Once CLABSI occurs, it significantly increases the risk of mortality, long of hospital stay, and healthcare economic burden. In recent years, multiple large-scale clinical studies on the diagnosis, treatment, and prevention of CLABSI have been completed, providing evidence-based medical support for related practices. Additionally, evolving global trends in antibiotic resistance epidemiology and the development of novel antimicrobial agents necessitate adjustments in clinical management strategies. Based on these developments, the Chinese Society of Critical Care Medicine has updated and revised the Guideline on the Prevention and Treatment of Intravascular Catheter-Related Infections (2007). This guideline was developed following the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system for evidence quality assessment. Guided by clinical questions, the working group initiated the process by defining key clinical issues, conducting literature searches, screening studies, performing meta-analyses, and synthesizing evidence-based findings to draft preliminary recommendations. These recommendations underwent iterative revisions through expert panel reviews, remote and in-person meetings, and two rounds of voting by the Standing Committee of the Chinese Society of Critical Care Medicine before finalization. The guideline comprises 52 recommendations, focusing on adult patients with central venous catheters in ICU. Key areas addressed include: selection of catheter insertion sites and techniques, catheter type and design, catheter management, prevention, diagnosis, and treatment of CLABSI. The guideline aims to provide ICU healthcare professionals with best practices for central line management, ensuring standardized clinical protocols for adult CLABSI.

OBJECTIVE: To analyze the clinical characteristics, microbiological analysis, and drug resistance patterns of intensive care unit (ICU) bloodstream infection. METHODS: A prospective cohort study method was employed to collect clinical data from patients suspected of bloodstream infection (BSI) during their stay in ICUs across 67 hospitals in 16 provinces and cities nationwide, from July 1, 2021, to December 31, 2022. Electronic data collection technology was used to gather general information on ICU patients, including gender, age, length of hospital stay, as well as diagnostic results, laboratory tests, imaging studies, microbiological results (including smear, culture results, and pathogen high-throughput testing), and prognosis. Patients were divided into a BSI group and a non-BSI group based on the presence or absence of BSI; further, patients with BSI were categorized into a drug-resistant group and a non-drug-resistant group based on the presence or absence of drug resistance. Differences in the aforementioned indicators between groups were analyzed and compared; variables with P < 0.10 in the univariate analysis were included in a multivariate Logistic regression analysis to identify risk factors for mortality and drug resistance in ICU patients with BSI. RESULTS: A total of 2 962 ICU patients suspected of BSI participated in the study, including 790 in the BSI group and 2 172 in the non-BSI group. Patients in the BSI group were mainly from East China and Southwest China, with significantly higher age and mortality rates than those in the non-BSI group. Among ICU patients with BSI, Staphylococcus had the highest detection rate (8.10%), followed by Klebsiella pneumoniae (7.47%); there were 169 cases in the drug-resistant group and 621 cases in the non-drug-resistant group; 666 cases survived, and 124 cases died (mortality was 15.70%). There were statistically significant differences between the death group and the survival group in terms of age, regional distribution, and bloodstream infections caused by Gram negative (G^-) bacilli, Enterococcus faecium, Aspergillus, and Klebsiella pneumoniae; multivariate Logistic regression analysis showed that age [odds ratio (OR) = 1.01, 95% confidence interval (95%CI) was 1.00-1.03], regional distribution (OR = 4.07, 95%CI was 1.02-1.34), Enterococcus faecium infection (OR = 3.64, 95%CI was 1.16-11.45), and Klebsiella pneumoniae infection (OR = 2.64,95%CI was 1.45-4.80) were independent risk factors for death in ICU patients with BSI (all P < 0.05). There were statistically significant differences between the drug-resistant group and the non-drug-resistant group in terms of age and bloodstream infections caused by Gram positive (G⁺) cocci and G^- bacilli; multivariate Logistic regression analysis showed that age (OR = 1.01,95%CI was 1.00-1.03), G^- bacilli infection (OR = 2.18, 95%CI was 1.33-3.59), Escherichia coli infection (OR = 0.28,95%CI was 0.09-0.84), and Enterococcus faecium infection (OR = 3.35, 95%CI was 1.06-10.58) were independent risk factors for drug resistance in ICU patients with BSI (all P < 0.05). CONCLUSIONS Bloodstream infections may increase the mortality of ICU patients. Older age, regional distribution, Enterococcus faecium infection and Klebsiella pneumoniae infection can increase the mortality rate of ICU patients with BSI; bloodstream infections caused by G^- bacilli are prone to drug resistance, but have no significant impact on the mortality of ICU patients with BSI.

Introduction: Intensive care unit (ICU) patients are at the greatest risk of acquiring nosocomial infections, partly because of their serious underlying disease, but also by exposure to life-saving invasive procedures. Hospital-acquired infections increase patient morbidity, increase the length of hospital stay and hospital costs, and also increases mortality rate. The basic knowledge of organisms infecting ICU patients is very important to empirically select appropriate antibiotics, so that the most likely infecting organisms are addressed. Objective: The aim of the study was to find out the etiologic agents causing infection in medical intensive care unit patients. Results In our study of 289 patients, 180 (62.3%) showed a growth of organism during the stay in ICU. The most common site of infection was the respiratory tract in 138 patients (47.8%) with 60 patients (20.8%) showing Acinetobacter baumannii.

OBJECTIVE: To provide evidence for further reducing the incidence of central line-associated bloodstream infection (CLABSI) according to investigation of the prevention and control of CLABSI in intensive care unit (ICU) in Shandong Province. METHODS: The questionnaire was developed by experts from Shandong Critical Care Medical Quality Control Center, combining domestic and foreign guidelines, consensus and research. A convenient sampling method was used to recruit survey subjects online from October 11 to 31, 2023 in the province to investigate the management status of central venous catheter (CVC) in ICU units of secondary and above hospitals. RESULTS: A total of 201 valid data were collected, involving 186 hospitals in the province, with a total of 201 ICU units, mainly comprehensive ICU (91%). The beds in ICU units were mainly single rooms (89%) and triple rooms (79%), and the ratio of doctors to total beds was 0.54 : 1. The training on the knowledge and operation of intravascular catheter-associated bloodstream infection in each ICU unit was mainly irregular (49%), and 96% of the catheter operators were authorized by the hospital. In terms of CVC selection, 89% of ICU units used dual-chamber CVC, and 86% of ICU units used catheters without antibiotic coating. When selecting the placement site, for conventional CVC catheterization, 65% preferred subclavian vein. Femoral vein was preferred in 87% of ICU units undergoing continuous renal replacement therapy. 95% of ICU units had established standardized operation procedure (SOP) for CVC placement. 86% of ICU units were capable of ultrasound positioning or guided puncture at the time of catheterization. During catheterization, 88% of ICU units met the sterile dress code. Before and after catheterzation, 81% and 77% of ICU units standardized hand hygiene. Only 31% of ICU units were covered from head to toe by aseptic wipes. For the choice of skin disinfectant, the majority of ICU units (72%) only used iodophor. After tube placement, 54% of ICU units chose sterile transparent dressing and 25% chose sterile gauze dressing. 98% of ICU units were sutured to secure the catheter. Regarding catheter replacement and removal, 45% of ICU units could not be removed or replaced within 2 days in emergency situations where the principle of sterility was not guaranteed. When CLABSI was suspected, 55% of ICU units were able to obtain the catheter tip, transcatheter blood culture, and contralateral peripheral vein blood culture at the same time. For CVC replacement frequency, most ICU units (75%) would not be replaced regularly, and some ICU units would be replaced regularly, but the frequency of replacement was different. For CLABSI prevention and control, 82% of ICU units developed a verification form or supervision form. When analyzing the sources of CLABSI data, most of them were filled in by themselves (60%). As for the frequency of data analysis, 57% were once a month. CONCLUSIONS All ICU units in Shandong Province are standardized in terms of the authorization of operators, the formulation of SOP, the formulation and implementation of verification form and supervision form, ultrasound-guided puncture, and hand hygiene before and after catheterization. However, there are still deficiencies in the training on knowledge and operation of intravascular catheter-associated bloodstream infections, maximum aseptic coverage, catheter replacement and removal, and the reporting sources of CLABSI data, which need to be strengthened in the follow-up work. At present, the selection of CVC, the selection of catheterization site, the selection of skin disinfectant and the selection of dressings after catheterization still need further research.

This study aimed to explore key quality control factors that affected the prognosis of intensive care unit (ICU) patients in Chinese mainland over six years (2015-2020). The data for this study were from 31 provincial and municipal hospitals (3425 hospital ICUs) and included 2 110 685 ICU patients, for a total of 27 607 376 ICU hospitalization days. We found that 15 initially established quality control indicators were good predictors of patient prognosis, including percentage of ICU patients out of all inpatients (%), percentage of ICU bed occupancy of total inpatient bed occupancy (%), percentage of all ICU inpatients with an APACHE II score ⩾15 (%), three-hour (surviving sepsis campaign) SSC bundle compliance (%), six-hour SSC bundle compliance (%), rate of microbe detection before antibiotics (%), percentage of drug deep venous thrombosis (DVT) prophylaxis (%), percentage of unplanned endotracheal extubations (%), percentage of patients reintubated within 48 hours (%), unplanned transfers to the ICU (%), 48-h ICU readmission rate (%), ventilator associated pneumonia (VAP) (per 1000 ventilator days), catheter related blood stream infection (CRBSI) (per 1000 catheter days), catheter-associated urinary tract infections (CAUTI) (per 1000 catheter days), in-hospital mortality (%). When exploratory factor analysis was applied, the 15 indicators were divided into 6 core elements that varied in weight regarding quality evaluation: nosocomial infection management (21.35%), compliance with the Surviving Sepsis Campaign guidelines (17.97%), ICU resources (17.46%), airway management (15.53%), prevention of deep-vein thrombosis (14.07%), and severity of patient condition (13.61%). Based on the different weights of the core elements associated with the 15 indicators, we developed an integrated quality scoring system defined as F score=21.35%xnosocomial infection management + 17.97%xcompliance with SSC guidelines + 17.46%×ICU resources + 15.53%×airway management + 14.07%×DVT prevention + 13.61%×severity of patient condition. This evidence-based quality scoring system will help in assessing the key elements of quality management and establish a foundation for further optimization of the quality control indicator system.
