Reduction of hemodialysis catheter-related blood stream infections in intensive care units after systematic use of taurolidine-citrate-heparin locking solution.

Dialysis catheter-associated bacteremia in Intensive Care Units (ICUs) increases morbidity and mortality, prolongs hospital admission and increases admission costs. Taurolidine-Citrate-Heparin Locking Solution (TCHLS) is a catheter-locking solution with a broad antimicrobial activity against gram-positive and gram-negative bacteria and fungi. The aim of this study was to analyze the effect of systematic sealing of hemodialysis catheters in the ICUs of the Hospital Clínic de Barcelona on the incidence of hemodialysis catheter-related blood stream infections (CRBSI). CRBSI episodes of patients who underwent intermittent hemodialysis (IHD) during ICU admission were reviewed. TCHLS was established as a routine dialysis catheter sealing solution in the hospital ICUs in 2015. As a control group an historic pre-TCHLS group from 2010 to 2014 was used. The post-TCHLS period comprised from 2015 to 2018. A total of 243 and 266 patients required IHD in the pre- and post TCHLS periods, respectively. The number of CRBSI in the pre-TCHLS period was 18 (7.43%) as compared to 9 (3.38%) in the post-TCHLS period (p = 0.043). All infections were from percutaneous catheters except for three catheters that were tunneled. There was no association between the location of the catheter and the incidence of CRBSI. The most frequent isolated microorganisms were Gram positive bacteria (48.38%), with a global predominance of Staphylococcus epidermidis (32.25%). There were no significant differences in the median days from the start of hemodialysis to the onset of bacteremia (23.5 days in pre-TCHLS group vs 21 days in the post-TCHLS). There were also no significant differences between the days of ICU stay in the CRBSI in both groups or in mortality, being the overall mortality of 65.9%. In our population, the systematic application of TCHLS in the sealing of dialysis catheters in critically ill patients reduces the incidence of CRBSI in ICUs.

Healthcare-associated infections in patients with COVID-19: is it different from the pre-pandemic period?

Healthcare-associated infections (HAIs) are common in intensive care unit (ICU) patients and may cause devastating consequences. However, the prevalence of HAI and its effects on in-hospital mortality among critically ill COVID-19 patients is ambiguous. We determined the prevalence of HAI and the rate of mortality in critically ill COVID-19 patients and compared it with pre-pandemic ICU patients. This retrospective study was conducted with adult ICU patients admitted to Gazi Yaşargil Training and Research Hospital (Diyarbakir,Turkey) in April-November 2019 (defined as the pre-pandemic period) and in April-November 2020 (defined as the pandemic period). All patients in the pandemic period had COVID-19, while none in the pre-pandemic period did. Patients diagnosed with HAIs during the in-hospital follow-up period were recorded. Of 4596 enrollees, 3386 (73.7%) were pandemic-period patients and 1210 (26.3%) were pre-pandemic-period patients. HAI prevalence was significantly higher at 5.9% (n = 71) in the pandemic-period patients and 2.7% (n = 91) in the pre-pandemic-period patients (p < 0.001). Comorbidities including hypertension (63.4% vs 14.2%, p < 0.001), diabetes mellitus (39.4% vs 8.8%, p < 0.001), and coronary artery disease (30.9% vs 10.9%, p = 0.002) were significantly more frequent in pandemic-period HAI-positive patients. The most common HAI was catheter-related bloodstream infection in both groups, with similar frequency (p = 0.652). In-hospital mortality rate was 85.9% versus 65.9% in pandemic- versus pre-pandemic-period HAI-positive patients (p < 0,05). The prevalence of HAI and the in-hospital mortality rate was significantly higher among pandemic-period patients.

Reducing catheter-related bloodstream infections using Lean Six Sigma methodology

BackgroundCentral venous catheters (CVC) are used for dialysis in end-stage renal disease patients, presenting a significant risk for Catheter-Related Bloodstream Infections (CRBSI). While Lean Six Sigma has been effective in reducing CRBSI, its efficacy outside intensive care units (ICU) remains less explored. This study aims to evaluate the effectiveness of Lean Six Sigma in mitigating CRBSI risks among non-ICU hemodialysis patients.MethodsThe study was conducted in a nephrology department, focusing on patients undergoing hemodialysis with temporary CVC from February to December 2021. The Lean Six Sigma method, using Define-Measure-Analyze-Improve-Control (DMAIC) methodology, was implemented in 2022 to reduce CRBSI incidence. The 2021 CRBSI rate served as the benchmark, with a goal to reduce it by the end of 2022. Value-stream mapping, Fishbone Diagrams, and Root Cause Analysis identified potential CRBSI causes. After implementing targeted improvements, CRBSI rates before and after the intervention were compared.ResultsThe Lean Six Sigma method significantly decreased CRBSI incidence from 12.79 to 2.32 per 1,000 catheter-days following the implementation of targeted interventions (\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$\\:{\\chi\\:}^{2}$$\\end{document}=4.60, P = 0.05). This improvement was observed comparing February-December 2021 with January-December 2022.ConclusionThe findings demonstrate the effectiveness of the Lean Six Sigma method in non-ICU settings, suggesting broader applicability in hemodialysis patient care.

Use of local treatment in managing infections: Focus on antimicrobial locks, beads, and cement.

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. The purpose of this review is to describe important considerations with local antimicrobial therapies such as locks, beads, and cement for adjunctive infection management or prevention. Local delivery of antimicrobials with locks, beads, and cement has been used for infection management with retained devices in an effort to improve clinical success. However, their use has been controversial due to conflicting clinical data and logistical issues. Antimicrobial lock therapy (ALT) has been used for both adjunctive treatment and prevention of catheter-related bloodstream infections for certain pathogens and based on patient-specific scenarios. ALT has been a controversial method for sterilizing the catheter lumen by delivering high concentrations of antibiotics with or without heparin into the catheter for prolonged durations. Studies differ regarding the selection and concentrations of antibiotics, dwell duration, presence of heparin in the ALT, clinical outcomes/definitions, and use for prevention or treatment of catheter-related bloodstream infections. Antibiotic beads and cement have been used for various surgical procedures but are predominately considered in orthopedic surgeries. Despite the widespread use of the antibiotic-loaded bone cement in orthopedics, studies differ regarding the selection and concentrations of antibiotics, clinical outcomes/definitions, and use for prevention or treatment of infections. Although antimicrobial locks, beads, and cement are commonly used for adjunctive treatment or prevention of infections, more data are needed to support their use to provide clinical efficacy and safety with consistent antimicrobial selection and logistics.

One and Done? An Evaluation of the Clinical Outcomes of Single- and Multi-Dose Dalbavancin Use in the Pediatric Population

Staphylococcus aureus is a leading cause of invasive bacterial infections in the pediatric population. In general, data surrounding the use of newly approved antimicrobials within children are lacking. Dalbavancin is a long-acting lipoglycopeptide that shows promise for off-label use in adults given its unique pharmacokinetics and in vitro potency against common Gram-positive isolates; however, evidence to supports its use in children is limited. We report the use of dalbavancin in three pediatric cases in patients aged 17 months of age, 3 years of age, and 11 years of age. All infections were caused by S. aureus (66.7% methicillin-resistant S. aureus) representing varied disease, including an osteoarticular infection and catheter-related bloodstream infection. Furthermore, all patients had pediatric infectious diseases involvement. Following the utilization of DAL, high clinical success and low rates of adverse effects were observed with high patients’ and parents’ satisfaction. While larger, confirmatory real-world studies are needed, our findings support safe off-label DAL use in select pediatric patients.

Central venous catheter-related infection: does insertion site still matter? A French multicentric cohort study.

We aim to evaluate the association between central venous catheter (CVC) insertion site and microbiological CVC complications in a nationwide cohort. This study was conducted using the healthcare-associated infection surveillance cohort "REA-REZO" involving 193 intensive care units (ICUs). All CVC inserted and removed during the same ICU stay between January 1st 2018 and December 31st 2022 were eligible but only those whose tips were sent for microbiological analysis were included. Primary objective was to describe CVC insertion sites and subsequent catheter-related bloodstream infection (CRBSI). Out of 126,997 CVCs, 71,314 were not sent for tip culture, and only 55,663 CVCs were included, (30,548 in internal jugular [IJ], 14,423 in femoral and 10,692 in subclavian [SC] sites). The incidence of CRBSI was 0.7 [0.6-0.8] in the IJ site, 0.7 [0.6-0.9] in the femoral site, and 0.6 [0.4-0.7] CRBSI per 1000 CVC days in the SC site (p = 0.248). The multivariable Poisson regression model showed no differences of CRBSI incidence rates between the three insertion sites. Microorganisms observed in CRBSI were coagulase-negative Staphylococci (27.9%), Enterobacterales (27.5%), non-fermenting Gram-negative Bacilli (10.4%), Candida sp. (16.9%), and Staphylococcus aureus (16.9%). Low CRBSI incidence rates were reported. CRBSI incidences rates were similar in the three insertion sites. Uncertainty remains due to potential selection bias since many CVCs had to be excluded.

Incidence, Risk Factors, Organism Types, and Outcomes of Catheter-Related Bloodstream Infections in Hemodialysis Patients.

Background Patients undergoing hemodialysis for End-Stage Renal Disease (ESRD) are at risk for Hemodialysis Catheter-Related Bloodstream Infections (CRBSIs). This study evaluates the incidence, risk factors, organism types, and outcomes of CRBSI in adult patients on maintenance hemodialysis at King Faisal Hospital, Rwanda. Methods This was a prospective cohort study of adult patients with end-stage renal disease undergoing hemodialysis via central venous hemodialysis catheters at King Faisal Hospital, Rwanda. Upon receiving the IRB approval, 81 eligible patients, women, and men aged between 19 and 74, were enrolled. Restricted Mean Survival Time (RMST) analysis evaluated the risk factors for CRBSI. The statistical significance was determined using p-values, with a cut-off of 0.05. Results The incidence of CRBSI was found to be 0.78 episodes per 1,000 catheter-days. Acute hemodialysis catheter type and anemia were associated with increased risk for CRBSI, with a P-value less than 0.05. In addition, all CRBSI cases were due to bacteria, with 52.63% gram-negative and 47.37% gram-positive. Out of 19 CRBSI events,nine cases (47.37%) required hospitalization with a median duration of seven days. Approximately half of the CRBSIs required catheter removal. No metastatic infection or death was noted. Conclusion The present study demonstrated that our hemodialysis unit has an incidence of 0.78 episodes per 1,000 catheter-days. Catheter type and anemia were significantly associated with CRBSI.

Catheter Selection in Home Parenteral Nutrition Patients and Noteworthy Definitions in The Diagnosis of Catheter Infections

The rising number of patients in need of long-term parenteral nutrition has necessitated home parenteral nutrition. Extended usage of central venous catheters and parenteral nutrition has given rise to its own complications. Among them, catheter-related bloodstream infections (CRBSI) are linked to life-threatening complications, especially sepsis, septic shock, and metastatic infections. The principal objective of this review is to define diagnostic methods, notable clinical and laboratory findings, and catheter salvage strategies towards preventing CRBSI, which include defining and interpreting blood culture and its results, its confounding variables and common shortcomings in routine practice. We will discuss the types and relative advantages and disadvantages of differing methods of central venous access and compare the common diagnostic definitions used by existing guidelines. CRBSI remains a serious complication, and we aim to debate when timely intervention will be necessary in light of the existing literature.

ThP8.5 - The Incidence and Characteristics of Complications Associated with Peripherally Inserted Central Venous Catheter and Midline Utilisation in Surgical Patients: A Retrospective Cohort Study

Abstract Background Peripherally inserted Central venous catheters (PICC lines) and midlines are pervasive clinical interventions. However, they are not devoid of adverse events such as catheter-associated thrombosis, mechanical anomalies, catheter-related bloodstream infections, and cellulitis. This study aims to investigate the nature and prevalence of these complications within a high-volume tertiary care centre. Methods A retrospective cohort study was conducted, including 473 patients subjected to PICC line and midline insertion within the Department of General Surgery during the period from June 2022 to June 2023. Results Over 5949 catheter days, a total of 73 complications were identified, reflecting an incidence rate of 15.43% (12.27 per 1000 catheter days). Notably, catheter-associated infections were predominant, manifesting at a rate of 4.20 per 1000 catheter days (n=25, 5.20%). Accidental withdrawal occurred at a rate of 3.87 per 1000 catheter days (n=23, 4.86%), incorrect positioning at 2.02 per 1000 catheter days (n=12, 2.54%), occlusion at 1.51 per 1000 catheter days (n=9, 1.90%), and rupture at 0.67 per 1000 catheter days (n=4, 0.84%). Conclusion The insertion of PICC and midline is associated with a substantial burden of morbidity, primarily characterised by catheter-associated infections. Emphasis on early identification of catheter-associated bloodstream infections is imperative. Mitigating these complications warrants the institution of a multidisciplinary educational initiative to augment nursing proficiency, coupled with the implementation of a local guideline governing PICC line and midline insertion and care.

A Study to Assess the Effectiveness of Informative Booklet Regarding Knowledge, Attitude and Practice Among Intensive Care Unit (ICU) Staff Nurses Regarding Prevention of Central Line Associated Blood Stream Infection (CLABSI)

Background: Nurses in Intensive Care Units (ICU) have a vital role in reducing Central line associated blood stream infections (CLABSI) if they are well educated to use strategies to decrease Central line associated blood stream infections (CLABSI) rate which are based on the center for disease control and prevention guidelines (CDC) to improve patient’s outcomes. Health-care-associated infections are a huge concern in the intensive care units (ICUs) across the globe. Nearly 90% of catheter-related bloodstream infections are caused by central venous catheters (CVCs). Central venous catheters (CVC) are commonly inserted in critically ill patients and play an important role for hemodynamic monitoring and delivery of crucial treatments. Central line-associated bloodstream infection (CLABSI) is a laboratory confirmed bloodstream infection occurring in a patient with a CVC in place for &gt;48 hours that is not related to an infection at any other site. Preventing nosocomial infections pose a great challenge in ICU, because of the multi-drug resistant organisms treated with broad-spectrum antibiotics. Clinical practice guidelines from various organizations are available for prevention of vascular catheter related infections. The Institute for Healthcare Improvement has introduced a “central line bundle” that includes the five best evidence-based practices to prevent CLABSI. This bundle includes hand hygiene, maximal barrier precautions during catheter insertion, skin antisepsis with chlorhexidine, optimal selection of the catheter site, with avoidance of the femoral vein and a daily assessment of line necessity, including the removal of an unnecessary line. Of these components, “hand hygiene” (HH) is the most convenient and cost effective to follow. “Hand Hygiene” HH prevents the transmission of pathogens and is a universal strategy to prevent all nosocomial infections. The World Health Organization has proposed a multimodal strategy; which includes five elements called the “Five Moments for Hand Hygiene”, as an evidence-based approach to prevent hospital-acquired infections. The five moments include, before touching the patient, before performing any a clean/aseptic procedure, after exposure/risk of body fluid, after touching the patient and after touching the patient surroundings. Therefore, the researcher was curious to know the effectiveness of informative booklet regarding knowledge, attitude and practice of intensive care unit staff nurses regarding prevention of central line associated blood stream infection (CLABSI).

Pediatric Chronic Intestinal Failure: Something Moving?

Pediatric chronic intestinal failure (PIF) is a rare and heterogeneous condition characterized by the inability of the patient's intestine to adequately absorb the required fluids and/or nutrients for growth and homeostasis. As a result, patients will become dependent on home parenteral nutrition (HPN). A MEDLINE search was performed in May 2024 with keywords "intestinal failure", "parenteral nutrition" and "pediatric". Different underlying conditions which may result in PIF include short bowel syndrome, intestinal neuromuscular motility disorders and congenital enteropathies. Most common complications associated with HPN are catheter-related bloodstream infections, catheter-related thrombosis, intestinal failure-associated liver disease, small intestinal bacterial overgrowth, metabolic bone disease and renal impairment. Treatment for children with PIF has markedly improved with a great reduction in morbidity and mortality. Centralization of care in specialist centers and international collaboration between centers is paramount to further improve care for this vulnerable patient group. A recently promising medical therapy has become available for children with short bowel syndrome which includes glucagon-like peptide 2, a naturally occurring hormone which is known to delay gastric emptying and induce epithelial proliferation. Despite advances in curative and supportive treatment, further research is necessary to improve nutritional, pharmacological and surgical care and prevention of complications associated with parenteral nutrition use.
