Pediatric candidemia is a major cause of invasive fungal infections in hospitalized children, but long-term data on epidemiology, management, and mortality predictors remain limited. We conducted an 18-year retrospective cohort study of 465 pediatric candidemia episodes at a tertiary referral center in western Turkey between 2008 and 2025. The primary outcome was crude 30-day mortality; associated factors were assessed using univariable analyses, Kaplan–Meier estimates, and multivariable logistic regression. Non-albicans Candida species predominated, with Candida parapsilosis as the most frequent isolate (46%). Central venous catheters were present in 88.4% of episodes. Crude 30-day mortality was 10.8%. Reduced survival was observed among patients without catheter removal and among those with thrombocytopenia, severe neutropenia, or immunosuppressive therapy. Among 341 episodes classified as central line-associated bloodstream infections, crude 30-day mortality differed significantly by catheter removal timing. Mortality was 4.8% with catheter removal within 72 h versus 13.1% without early removal (p = 0.022). Using a 48 h threshold, mortality was 3.1% with removal within 48 h versus 12.3% without removal within 48 h (p = 0.029). In multivariable analysis, failure to remove the catheter was the strongest independent factor associated with mortality (adjusted odds ratio, 6.63; 95% confidence interval, 2.85–15.42; p < 0.001). Antifungal resistance patterns were not consistently associated with mortality. In this large pediatric candidemia cohort, 30-day mortality was mainly associated with host vulnerability and modifiable management factors, underscoring the importance of timely source control.

Background/Objectives: Hand hygiene is a cornerstone of infection prevention, yet the extent to which multimodal institutional hand hygiene interventions translate into measurable reductions in healthcare-associated infections (HAIs) remains uncertain. This systematic review aimed to evaluate the association between hospital-wide or multi-ward multimodal hand hygiene interventions and clinical HAI outcomes in acute care hospitals. Methods: A structured literature search was conducted in PubMed, Scopus, Embase, and Google Scholar using a combination of Medical Subject Headings (MeSH) and free-text terms related to hand hygiene, healthcare-associated infections, hospital settings, and intervention strategies. Eligible studies were quasi-experimental designs, including before–after, controlled before–after, and interrupted time-series studies, evaluating multimodal hand hygiene interventions implemented at hospital-wide or multi-ward level and reporting clinical HAI outcomes. Two reviewers independently assessed risk of bias using the ROBINS-I tool, and certainty of evidence across major outcome categories was summarized using GRADE. Results: twelve studies met the inclusion criteria. Overall, multimodal hand hygiene interventions were generally associated with favorable directional trends in clinical outcomes. Reductions were most consistent for broader institutional HAI measures and some device-associated infections, particularly central line-associated bloodstream infections. In contrast, organism-specific outcomes, including methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus, and Clostridioides difficile, were more heterogeneous across studies and settings. All included studies were judged to be at serious or critical overall risk of bias, primarily because of confounding, lack of contemporaneous controls, co-interventions, and phased implementation. Conclusions: Multimodal hand hygiene programs in acute care hospitals may be associated with improvement in selected clinically relevant HAI outcomes, particularly at the institutional level. However, the overall certainty of evidence remains low to very low, and the strength of inference is limited by the non-randomized nature of the available studies and the difficulty of isolating the independent effect of hand hygiene within complex infection-prevention strategies.

Background/Objectives: Central line-associated bloodstream infection (CLABSI) remains a major healthcare-associated infection in intensive care units (ICUs). This study evaluated changes in CLABSI incidence following the implementation of a multimodal infection control intervention in the ICU. Methods: We conducted a quasi-experimental study in the adult ICUs of a referral hospital from January 2023 to December 2025. The interventions included staff education, performance feedback, infection control-led rounds, optimization of catheter practices, and reinforcement of environmental hygiene. The primary outcome was CLABSI incidence per 1000 central line-days. An interrupted time-series analysis using segmented Poisson regression with robust standard errors was used to assess temporal trends. Results: A total of 17 CLABSI cases occurred during the pre-intervention period, and 25 during the post-intervention period. There was no significant difference in CLABSI incidence between the two periods (incidence rate ratio, 1.07; 95% confidence interval, 0.58–1.98). However, interrupted time-series analysis demonstrated a significant decreasing trend in CLABSI incidence following the intervention (rate ratio, 0.89 per month; 95% confidence interval, 0.81–0.97; p = 0.01). This trend was observed despite the higher patient severity and increased use of advanced supportive therapies in the post-intervention period. The device utilization ratio and monthly blood culture rate remained unchanged. Avoidance of femoral venous access increased, and adherence to catheter-handling protocols significantly improved. Conclusions: A staged, multimodal intervention was associated with a significant decreasing trend in CLABSI incidence over time, suggesting a potential benefit of comprehensive infection prevention strategies in ICU settings.

Background/Objectives: Central line-associated bloodstream infections (CLABSIs) remain a leading healthcare-associated infection in intensive care units (ICUs), yet independent risk factors and evidence-based catheter duration thresholds have not been defined through analytical study designs in settings with endemic multidrug-resistant organisms (MDROs). Methods: A retrospective case–control study was conducted in the ICU of a tertiary teaching university hospital in western Türkiye (January 2019–December 2024). Cases (n = 74) were patients with confirmed CLABSIs per CDC/NHSN criteria; controls (n = 148) were randomly selected central venous catheter (CVC)-bearing patients without CLABSIs. A reduced multivariate logistic regression model (seven variables; events-per-variable ratio 10.6) identified independent risk factors. Results: In multivariate analysis, catheter duration (adjusted OR: 1.19 per day; 95% CI: 1.13–1.24; p < 0.001), renal replacement therapy (aOR: 3.66; 95% CI: 1.68–7.95; p = 0.001), vasopressor support (aOR: 3.04; 95% CI: 1.50–6.17; p = 0.002), APACHE-II score (aOR: 1.07 per point; 95% CI: 1.02–1.11; p = 0.002), lower Glasgow Coma Scale (aOR: 0.86 per point; 95% CI: 0.78–0.94; p = 0.002), mechanical ventilation (aOR: 2.48; 95% CI: 1.24–4.95; p = 0.010), and total parenteral nutrition (aOR: 2.33; 95% CI: 1.12–4.86; p = 0.024) were independently associated with CLABSI. The model demonstrated good discrimination (C-statistic: 0.864) and calibration (Hosmer–Lemeshow p = 0.425). Kaplan–Meier analysis showed CLABSI-free survival declining from 98.9% at day 7 to 42.9% at day 21 (log-rank p < 0.001); these within-study estimates reflect relative risk patterns given the artificial 1:2 case-to-control ratio. Receiver operating characteristic (ROC) analysis identified day 13 as an exploratory optimal cutoff (AUC: 0.818; 95% CI: 0.762–0.874; sensitivity: 77.0%; specificity: 74.3%). CLABSI-attributable ICU mortality was 20.3% (47.3% vs. 27.0%; p = 0.004). Late-onset CLABSIs (>10 days) were dominated by Gram-negative pathogens (68.3%) versus 35.7% in early-onset infections (Fisher’s exact p = 0.012), with Acinetobacter baumannii as the predominant organism (27.0%; 83.3% carbapenem-resistant). Conclusions: Each additional catheter-day is independently associated with a 19% increment in CLABSI odds, with an exploratory critical threshold at day 13 beyond which enhanced surveillance measures should be considered, pending external validation.

Background: Fever occurs frequently in patients with intracerebral hemorrhage (ICH) and is associated with worse functional outcomes. Rapid identification of the fever’s cause is crucial for guiding diagnostics and treatment. Data on the distribution of different fever causes in ICH are limited, and the diagnostic value of the day of fever onset remains uncertain. This study aimed to assess the distribution of fever causes in a large cohort of ICH patients and to evaluate whether temporal patterns of fever onset are associated with its underlying cause in a clinically meaningful manner. Methods: This retrospective single-center study included 547 patients with spontaneous ICH. Fever was defined as a body temperature exceeding 38.3 °C for at least two consecutive days. Fever causes were evaluated by two blinded investigators and categorized as infectious, central, or other causes. Infectious fever causes were further specified. Results: Fever occurred in 213 patients (39%) and was associated with longer hospital and ICU stays (both p < 0.01) and poor functional outcome (odds ratio 2.0, 95% CI 1.1–3.6). The three most frequent fever etiologies (>90% of cases) were pneumonia, central fever, and catheter-associated infections (i.e., urethral tract infections, ventriculitis, and central line-associated bloodstream infections). Median onset day differed across etiologies (overall p < 0.001): central fever developed earliest (2 [IQR 1–3] days), followed by pneumonia (5 [IQR 4–7] days) and catheter-associated infections (8 [IQR 5–12] days). Conclusions: In ICH, the day of fever onset may provide a useful clue to its etiology and could support clinical decision-making, but prospective validation is needed. Full article

Background/Objectives: The effective prevention and control of healthcare-associated infections (HAIs) require the active engagement of clinical staff, which depends on strong relationships between the Infection Prevention and Control Team (IPCT) and frontline healthcare personnel. The role of the Infection Control Physician (ICP) as a clinical leader is essential for supporting evidence-based practice and fostering collaboration. This study aimed to demonstrate the impact of leadership-oriented interventions—particularly the introduction of ICP consultations in hospital wards—on HAI surveillance quality. Methods: A retrospective observational quasi-experimental study was conducted in a single hospital in southern Poland between 2017 and 2024, excluding 2020–2021 due to the COVID-19 pandemic. HAI surveillance followed the ECDC HAI-Net methodology. The study included all hospitalized patients in wards where invasive medical devices or invasive procedures were used. The intervention consisted of expanding the IPCT, increasing managerial support, extending infection control nurses’ competencies, and implementing routine ICP medical consultations. Changes in HAI incidence rates between the pre-intervention (pre-IP) and post-intervention (post-IP) periods were analyzed for catheter-associated urinary tract infections (CAUTI), ventilator-associated pneumonia (VAP), and central line-associated bloodstream infections (CLABSI), expressed per 1000 device-days. Results: The overall device utilization increased from 0.44 to 0.54 per 1000 patient-days in the post-IP period. The utilization of microbiological diagnostic tests more than doubled, with marked increases in blood cultures (6.4% vs. 15.5%) and urine cultures (7.7% vs. 11.0%). No IPCT consultations occurred in the pre-IP period, while 874 consultations were recorded in the post-IP period. Th incidence rates for CAUTI and VAP increased (1.4 to 3.1 and 11.7 to 24.6 per 1000 device-days, respectively). The CLABSI incidence showed no significant overall change. Conclusions: Structural and functional changes in the IPCT, combined with the introduction of ICP consultations, substantially enhanced the quality and completeness of HAI surveillance in the analyzed hospital. The findings highlight the importance of leadership-driven engagement in improving infection prevention and control systems. Full article

This study explores how hospital location (rural/non-rural) may moderate the nurse staffing ratio’s impact on three hospital-acquired infections. This study used data from 2022 to 2024 on nurse staffing and hospital characteristics from the American Hospital Association Annual Survey and data on hospital-acquired infection rates from the Medicare Care Compare dataset provided by the Centers for Medicare and Medicaid Services. After removing missing values, the final dataset included 7997 hospital-year observations across the US. Independent variables include rural hospital designation, nursing hours per patient day, and RN FTE per adjusted day. The dependent variables included infection rates of Central Line-Associated Bloodstream Infection, Catheter-Associated Urinary Tract Infection, and Methicillin-Resistant Staphylococcus aureus. Multiple regression was performed in Stata 18. Our research found that across all three infection types, an increase in nursing hours per patient day is significantly associated with a decrease in the infection rate, and that impact was not moderated by hospital rurality. Extra time spent with patients in either a rural or non-rural hospital decreased hospital-acquired infection rates. While RN FTEs were included in the model, total nursing hours per patient day emerged as the more consistent predictor of lower hospital-acquired infection rates. Full article

Clinical infections caused by Saccharomyces cerevisiae develop infrequently. We report a case of central line-related bloodstream infection caused by S. cerevisiae in a patient with Clostridioides difficile colitis and central venous catheter placement. The administration of probiotics in C. difficile colitis was associated with fungemia caused by S. cerevisiae. This case suggests the potential for serious infection caused by S. cerevisiae in immunocompromised patients with C. difficile colitis. Removal of the central venous catheter may be important for a better prognosis in fungemia caused by S. cerevisiae. Full article

Background: Umbilical venous catheter (UVC) placement is common in neonates but carries risks of migration and infection. This study evaluates safety of a novel fixation technique using the umbilical cord clamp after a side-entry insertion. Methods: A retrospective analysis of 264 neonates was conducted at a tertiary center in order to assess safety of the novel UVC fixation method. The new technique involved side-entry catheter insertion without severing the cord, secured to the clamp with a sterile patch. Catheter tip position was confirmed and monitored every 24 h via ultrasound. Results: Catheter migration occurred in 18.9% of cases, mostly inward into the right atrium which was managed by repositioning. Migration into the ductus venosus requiring removal occurred in 0.7% of cases and unscheduled removal due to stump detachment in 1.5%. No central line-associated bloodstream infections (CLABSIs) were observed. Conclusions: The umbilical cord clamp method is a safe, single-operator alternative for UVC fixation. This technique had a low rate of catheter migration, did not increase the risk of infection, and was cost-effective and simple. Full article

The central venous catheter (CVC) is essential in the management of pediatric patients, allowing the administration of medications, parenteral nutrition, and other treatments. However, its use carries a high risk of central-line-associated bloodstream infections (CLABSI) and catheter-related bloodstream infections (CRBSI). Advanced chlorhexidine-impregnated dressings have been developed to reduce bacterial colonization, but their effectiveness in the pediatric population remains uncertain. The aim of this review is to evaluate the effectiveness of chlorhexidine-impregnated dressings compared to standard dressings in reducing CLABSI, CRBSI, and CVC colonization in pediatric patients. Randomized clinical trials published between 2005 and 2021 in PubMed, CINAHL, and Embase, in Italian or English, were selected. Methodological quality was assessed using the Joanna Briggs Institute (JBI) checklist. Relevant data were extracted and summarized in tables. Four studies, including a total of 733 pediatric patients (367 intervention, 366 control), were included. None reported a statistically significant reduction in CLABSI/CRBSI with the use of chlorhexidine-impregnated dressings. However, two studies showed a significant reduction in catheter colonization in the intervention group. Current evidence does not support a superior effect of chlorhexidine-impregnated dressings in preventing CLABSI/CRBSI in pediatric patients, although they may reduce catheter colonization. Randomized trials with larger samples and specific methodologies are needed to clarify the true clinical impact. Full article

Background: Dedicated bundles were proven to reduce CLABSIs in a neonatal intensive care unit (NICU). Methods: We performed an observational pre–post study to evaluate the impact of a bundle for CLABSI prevention in our NICU. All umbilical vein catheters (UVCs) and epicutaneo-caval catheters (ECCs) with dwell time > 2 days were included. The primary outcome was CLABSI rate/1000 central line days. Results: A total of 145 catheters (67 UVCs and 78 ECCs) and 142 catheters (65 UVCs and 77 ECCs) were inserted before and after bundle implementation, respectively. The duration of the UVC was significantly shorter before than after the bundle [4 (3–6) vs. 8 (6–11) days; p < 0.0001], while the duration of the ECC did not differ [10 (6–17) vs. 11 (6–19) days; p = 0.711]. CLABSI were less frequent after than before bundle (3.6 vs. 10.7/1000 CL days; p = 0.042); both UVC-related and ECC-related CLABSI were significantly reduced (0 vs. 7.2/1000 CL days, p = 0.015; and 4.4 vs. 12.3/1000 CL days, p = 0.044, respectively). The Kaplan–Meier curve for ECC-related CLABSIs showed no differences between the two periods (p = 0.255), but higher survival without CLABSIs after vs. before bundle was found if considering only ECC with dwell time < 14 days (p = 0.040). Gestational age (p = 0.004) and bundle (p = 0.026) were predictive factors for CLABSIs. Non-infective complications were significantly less frequent after than before bundle (11 vs. 20%, p = 0.033). Conclusions: Our bundle reduced the overall CLABSI rate, and both UVC- and ECC-related CLABSI occurrence. The efficacy for the reduction in ECC-related CLABSIs seems limited to the first 14 days of dwell time. Full article

Background: Central line-associated bloodstream infections (CLABSIs) in neonatal intensive care units (NICUs) pose a significant risk, especially for very low birth weight infants due to their immature immune systems and the need for invasive procedures. The implementation of evidence-based bundles, as recommended by international guidelines, has proven effective in significantly reducing CLABSI rates, improving clinical outcomes, and lowering hospital costs. However, evidence from long-term, real-world quality-improvement programs in European NICUs—especially those using repeated PDSA cycles and detailed monitoring across multiple periods—remains limited. Methods: This quality improvement prospective study, conducted in the NICU of “V. Buzzi” Children’s Hospital, aimed to reduce high CLABSI rates using a plan-do-study-act (PDSA) framework. A multidisciplinary team developed and implemented a new evidence-based central line bundle in 2021, focusing on standardized practices, enhanced training, and monitoring. The study analyzed 594 CVCs placed in 348 neonates across a total 4-years period (P1–P12). Results: Implementation of a central line bundle significantly reduced CLABSI rates from 29.1 to 2.2 per 1000 CVC days (p-value 0.002), with notable variations during intermediate periods. Birth weight and study period progression were the only variables significantly associated with CLABSI reduction. Conclusions: Infection rates dropped significantly post-intervention, achieving zero in one of the latest periods: continuous monitoring, staff training, and targeted interventions were pivotal. Future efforts will focus on refining practices, increasing tunneled centrally inserted central catheter (CICC) use, and sustaining prevention measures. Full article

Background/Objectives: Umbilical venous catheters (UVCs) and umbilical artery catheters (UACs) are essential for neonatal care, facilitating medication delivery, nutritional support, and blood pressure monitoring. However, malposition and prolonged catheter dwell time can lead to severe complications, including central line-associated bloodstream infections (CLABSIs). This study aims to evaluate the benefits of ultrasound in confirming catheter tip location, which may impact infection risk, and to assess the effectiveness of modification of the securing method. Methods: This prospective randomized controlled study was conducted from May 2022 to December 2024 at an NICU in Taiwan. Neonates requiring umbilical catheters were randomly assigned to three groups. In Group 1, the catheter length was calculated using a formula, X-ray confirmation was used, and the catheter was secured with traditional tape. In Group 2, ultrasound confirmation was used and the catheter was secured with FoamLite™ sterile dressing and transparent film. In Group 3, ultrasound confirmation was used and the catheter was secured with traditional tape. The outcomes were the rate of complications of the catheters. Results: Groups 2 and 3 demonstrated significantly lower malposition rates, microbial colonization, and CLABSI incidence compared to Group 1 (p = 0.001, 0.006, and 0.026, respectively). No significant difference was observed between Groups 2 and 3, suggesting that accurate tip positioning was more influential in reducing CLABSIs than the securing method itself. Conclusions: Ultrasound guidance improves catheter placement accuracy, minimizes malposition, lowers CLABSI risk, and reduces radiation exposure, supporting its broader implementation in NICUs.

Background: Despite efforts to rely on arteriovenous fistulas/grafts for maintenance hemodialysis, a significant number of patients still depend on tunnel hemodialysis catheters for treatment. This poses a risk factor for central line-associated bloodstream infection (CLABSI) and, subsequently, vascular access compromise. Method: We conducted a retrospective study in five dialysis centers to determine the potential factors resulting in vascular access loss, CLABSI incidence, and microbe distribution patterns in Saudi Arabia at centers under the Ministry of National Guard Health Affairs. Adults who regularly received hemodialysis and had positive blood cultures between January 2019 and December 2023 were the subjects of the study. Results: Our study identified the presence of tunnel infection (p < 0.001), the presence of a Gram-negative pathogen (p = 0.036), and a high body mass index (BMI > 30) (p = 0.04) as potential risk factors leading to the loss of tunnel central venous catheters. In contrast, there was a lower probability of central venous catheter loss due to Gram-positive pathogens (p = 0.01). The CLABSI rate was 1.55 per 100 patients per month over a five-year period. Patients with CVC required more hospital treatment and had a significantly higher rate of vascular access loss (p < 0.001). Both central and peripheral blood cultures had nearly identical microbe spectra. Methicillin-sensitive Staphylococcus aureus (MSSA), Methicillin-resistant Staphylococcus aureus (MRSA), and Staphylococcus epidermidis had the highest prevalence rates among Gram-positive organisms. Among the Gram-negative bacteria, Enterobacter cloacae was the most common, followed by Klebsiella pneumonia and Pseudomonas aeruginosa. Conclusions: Our findings indicate the need for rigorous measures and interventions to prevent Gram-negative infections and decrease the reliance on central venous catheters, to decrease infections in hemodialysis patients, and decrease morbidity and cost. Strict hand hygiene, patient education, and surveillance programs are recommended to monitor these patients. Full article

Long-term intravenous therapies often necessitate the use of peripherally inserted central catheters (PICCs). Antimicrobial-coated PICCs have been introduced to minimize central line-associated bloodstream infections (CLABSIs). A decision-analytic cost-effectiveness model was developed from a societal perspective, utilizing real-world data concerning PICC-related complications and costs from Class 3A hospitals and community hospital settings in China. The analysis compared the quality-adjusted life years (QALYs) for patients receiving antimicrobial-coated PICCs versus standard PICCs, with catheter-associated costs included. Incremental cost-effectiveness ratios (ICERs) were calculated in Chinese Yuan (CNY) per QALY gained. Patients with antimicrobial-coated PICCs experienced slightly fewer complication-related events, leading to significantly lower costs for managing complications. In the Class 3A hospital setting, the average total cost per patient was lower with antimicrobial-coated PICCs (CNY 62,800) compared to standard PICCs (CNY 102,900), primarily due to the reduced expenses for treating CLABSIs and related unknown fever. The ICER demonstrated that the coated PICC was the strongest option, showing a negative ICER (cost-saving of approximately CNY 4 million per QALY gained in the base-case Class 3A hospital scenario). In community hospital care scenarios, the cost advantage of antimicrobial-coated PICCs remained. Thus, the antimicrobial-coated PICC strategy was cost-saving, providing equal or improved health outcomes at lower costs in China’s medical center and community hospitals, making it a more efficient choice for long-term vascular access.
