Objectives: The evaluation of effectiveness of implemented actions to limit intravascular catheter-related bloodstream infection rates.
Introduction: We have analyzed actions taken in nineteen wards in the St. Lukas District Hospital in Tarnów. During seven-year study period, from 2005 to 2011, 207 673 hospitalized patients were supervised. A study was done among all patients with peripheral intravenous catheters and central venous catheters.
Material And Methods: Standard statistic tools and definitions of nosocominal infections used by US Centers for Disease Control and Prevention were used. Intravascular catheter-related bloodstream infection rates has been calculated by a formula: (number of catheter-related bloodstream infections/number of person-days with catheters) x1000.
Results: During the period study, decrease in frequency of occurrence was obtained: venous catheter-related bloodstream infections decreased from 2.8 to 0.4 per 1000 person-days, central venous catheter-related bloodstream infections decreased from 8.9 to 3.0 per 1000 person-days, peripheral intravenous catheter-related bloodstream infections decreased from 0.6 to 0.3 per 1000 person-days. The most common causative agent of venous catheter-related bloodstream infections was in 44% of cases Staphylococcus CNS and in 19% of cases Staphylococcus aureus.
Conclusions: It is possible to significantly decrease intravascular catheter-related bloodstream infection rates by taking preventive actions combined with intensive education of medical personnel.

Department of Pharmacy, The Second Affiliated Hospital of Dalian Medical University, Dalian, Liaoning, China.
Background: Hematopoietic stem cell transplantation (HSCT) patients often receive consecutive intensive chemotherapy, which can lead to gastrointestinal complications and acute graft-versus-host disease (GVHD), placing patients at high nutritional risk.
Aim: This retrospective study aimed to evaluate the benefits of nutritional support in maintaining nutritional status, reducing weight loss without increasing the incidence of catheter-related bloodstream infections (CRBSI) or liver dysfunction, and improving clinical outcomes in HSCT patients at high nutritional risk.
Methods: A total of 526 patients who underwent HSCT were included in the study.

Objective: The aim of our study was to describe and analyze HAI incidence, etiology and risk factors in pediatric intensive care unit (ICU).
Background: Intensive care patients are at high risk of hospital-acquired infections (HAI) due to their underlying diseases and exposure to invasive devices.
Methods: The study group consisted of patients admitted to children's hospital ICU for more than 2 days during a six-month period (267 patients, 1570 patient-days).

Electronic address:
Objective: To explore a definition for complicated coagulase-negative staphylococci bloodstream infections (CoNS BSI), and to identify predictors for mortality.
Methods: Prospective cohort study conducted from October 2016 to March 2017 in 26 Spanish hospitals. Complicated CoNS BSI criteria included lack of early catheter removal in catheter-related cases, foreign indwelling implant, persistent bacteremia, fever ≥72 hours on active therapy, metastatic infection or deep-seated focus and infective endocarditis.

Nosocomial bloodstream infections with multidrug-resistant microorganisms have become a common health threat in intensive care settings worldwide. Understanding antimicrobial resistance and the outcomes of these infections is crucial for addressing this issue. This study aimed to investigate the burden, antimicrobial resistance, and 28-day outcomes of nosocomial bloodstream infections in the intensive care unit.
