ABSTRACT
BACKGROUND: A significant number of patients require non-tunneled haemodialysis catheters (NTHCs) in the event of an urgent need for immediate haemodialysis in developing countries. Catheter-related bloodstream infections (CRBSIs) are a major concern in haemodialysis, but there is a lack of local epidemiological data. This study aimed to determine the incidence of CRBSI, causative agents and associated risk factors in a tertiary care hospital in Sri Lanka. METHODS: A prospective study was conducted at the dialysis unit of Colombo South Teaching Hospital, Sri Lanka from December 2019 to August 2020. Adult patients who had haemodialysis for the first time with NTHCs were included. RESULTS: Of 149 dialysis patients (104-jugular vein and 45-femoral vein, mean age 58 ± 13.7 years, mean duration of catheterization 7.9 ± 3.4 days), the incidence of CRBSI was 13.58 per 1000 catheter days. Serum albumin levels, capillary blood sugar levels at admission, haemoglobin levels and duration of catheterization were significantly associated with CRBSI. Prescence of diabetes and patients with ESRD who started routine haemodialysis had a significantly higher risk of CRBSI. Gram-positive bacteria were the most common microorganisms associated with CRBSI (87.5%). CONCLUSIONS: Our results show high rates of infection with temporary vascular catheters in Sri Lanka, mainly due to Gram-positive bacteria. Diabetes mellitus, duration of catheterisation, low serum albumin, haemoglobin level and CBS on admission were identified as significant risk factors for CRBSI. Management strategies tailored to specific centers should be established in the nation to optimise catheter care and to monitor local microbiology for appropriate empirical antimicrobial treatment.

INTRODUCTION: Endocarditis associated with medical care is a rare and serious entity. The risk of occurrence is increased in hemodialysis patients due to the immunosuppression and the multiplicity of vascular accesses of different kinds. The mode of revelation can be variable given the diversity of symptoms it causes. Herein, we describe the case of endocarditis associated with medical care in a patient with renal failure who presents with neurological symptoms. OBSERVATION: A 38-year-old patient with a history of kidney disease in the hemodialysis stage presented to the emergency room with altered neurological status in the context of fever. The patient's condition requires airway control, sedation, and vasopressor medication. Brain imaging revealed Fisher 4 subarachnoid hemorrhage with brain turgor. Transthoracic and transesophageal cardiac ultrasound exploration revealed infective mitro-aortic endocarditis with trigonal abscess fistulized in the left ventricle and destruction of the aortic valve with massive regurgitation. The additional imaging in a second step did not highlight any images of mycotic aneurysm. The indication for early surgery was not approved given the hemodynamic instability and the poor intracerebral hemodynamics demonstrated by transcranial doppler ultrasound. The initial outcome under antibiotic treatment and renal replacement was favorable. But the subsequent course was fatal due to septic shock with multiple organ failure. CONCLUSION: The diagnosis of infective endocarditis should always be considered in hemodialysis patients presenting in a septic state with signs of systemic involvement. It is a source of mortality in these debilitated patients.

Introducción. La infección asociada a catéter venoso central (CVC) es la principal complicación que presentan los pacientes en hemodiálisis en los que se usa este tipo de acceso. Objetivo. Estimar la incidencia de bacteriemia asociada a CVC no tunelizado, analizar la frecuencia de agentes causales y explorar factores de riesgo asociados en niños en hemodiálisis. Población y métodos. Estudio retrospectivo realizado en niños en hemodiálisis por CVC no tunelizado entre el 1 junio de 2015 y el 30 de junio de 2019. Para evaluar factores de riesgo predictores de bacteriemia asociada a CVC, se realizó regresión logística. Los factores de riesgo independiente se expresaron con odds ratio con sus respectivos intervalos de confianza del 95 %. Se consideró estadísticamente significativo un valor de p <0,05. Resultados. En este estudio se incluyeron 121 CVC no tunelizados. La incidencia de bacteriemia fue de 3,15 por 1000 días de catéter. El microorganismo aislado con mayor frecuencia fue Staphylococcus epidermidis (16 casos, 51,5 %). La infección previa del catéter fue el único factor de riesgo independiente encontrado para el desarrollo de bacteriemia asociada a CVC no tunelizado (OR: 2,84; IC95%: 1,017,96; p = 0,04). Conclusiones. El uso prolongado de los CVC no tunelizados para hemodiálisis crónica se asoció con una incidencia baja de bacteriemia. Los gérmenes grampositivos predominaron como agentes causales. La presencia de infección previa del CVC aumentó en casi 3 veces el riesgo de bacteriemia asociada a CVC en nuestra población pediátrica en hemodiálisis.
Introduction. Central venous catheter (CVC)-related infection is the main complication observed in patients undergoing hemodialysis with this type of venous access. Objective. To estimate the incidence of non-tunneled CVC-related bacteremia, analyze the frequency ofcausative agents, and explore associated risk factors in children undergoing hemodialysis. Population and methods. Retrospective study in children receiving hemodialysis via a non-tunneled CVC between June 1 st, 2015 and June 30 th, 2019. A logistic regression was carried out to assess risk factors that were predictors of CVC-related bacteremia. Independent risk factors were described as odds ratios with their corresponding 95% confidence interval (CI). A value of p < 0.05 was considered statistically significant. Results. A total of 121 non-tunneled CVCs were included in this study. The incidence of bacteremia was 3.15 per 1000 catheter-days. The most commonly isolated microorganism was Staphylococcus epidermidis(16 cases, 51.5%). Prior catheter infection was the only independent risk factor for the development of bacteremia associated with non-tunneled CVC (OR: 2.84, 95% CI: 1.017.96, p = 0.04). Conclusions. Prolonged use of non-tunneled CVCs for chronic hemodialysis was associated with a low incidence of bacteremia. Gram-positive microorganisms prevailed among causative agents. A prior CVC infection almost trebled the risk for CVC-related bacteremia in our pediatric population receiving hemodialysis.

OBJECTIVES: Indwelling urinary catheter is closely associated with the occurrence of urinary tract infection (UTI). Herein, we further explored the correlation of urinary catheter indwelling time and UTI. METHODS: Retrospectively, the medical data of nosocomial patients (n = 681) were collected during two quarters of April 2023 to June 2023 (the second quarter, 23.4-23.6, n = 330) and July 2023 to September 2023 (the third quarter, 23.7-23.9, n = 351). The baseline data and incidence of catheter-related UTI were analysed. The total hospitalisation days and indwelling urinary catheter days of patients in five departments were assessed, namely, coronary care unit (CCU), respiratory intensive care unit (RICU), surgical intensive care unit (SICU), neurology intensive care unit (NICU) and cardiac surgical intensive care unit (CSICU) departments. The correlation between hospitalisation days/indwelling urinary catheter days and the occurrence of UTI was evaluated by Spearman correlation analysis. RESULTS: In the CCU, RICU, SICU, NICU and CSICU departments, the number of patients was 463, 83, 29, 91 and 15, respectively. During 23.4-23.6, the incidence of catheter-associated UTI (CAUTI) was 0, 2.85, 6.12, 0 and 12.99 per 1000 urinary catheter days in CCU, RICU, SICU, NICU and CSICU, respectively. During 23.7-23.9, the incidence of CAUTI was 2.98, 6.13, 8.66, 0 and 0 per 1000 urinary catheter days in CCU, RICU, SICU, NICU and CSICU, respectively. Notably, hospitalisation days/indwelling urinary catheter days were positively correlated with the occurrence of CAUTI in each quarter (p < 0.05). CONCLUSIONS: There was a positive correlation between urinary catheter indwelling time and the occurrence of UTI.

OBJECTIVES: Peripherally inserted central catheters are commonly used in cancer patients and provide vascular access for the administration of chemotherapy, antibiotics, or parenteral nutrition. Besides many advantages, they represent a source of possible complications such as catheter related blood stream infection, catheter occlusion, or thrombosis. In this study, the catheter-related complication rate between oncologic and non-oncologic patients was compared. METHODS: This retrospective cohort-study included 411 patients who underwent their first catheter placement at the Vienna General Hospital-Medical University of Vienna from January 2013 to June 2018. Patient demographics and catheter-related parameters were collected and statistically analyzed using a competing risk model. RESULTS: Mean catheter dwell time was 27.75 days. The overall complication rate was 7.54% (2.72 per 1000 catheter days). Underlying malignant disease (hazard ratio: 0.351, 95% confidence interval [CI]: 0.133-0.929, Pâ¯=â¯.035) and chemotherapy administration (hazard ratio: 2.837, 95% CI: 1.088-7.394, Pâ¯=â¯.033) were significantly associated with the occurrence of any kind of complication. Catheter related blood stream infection was observed among 11 (2.68%) patients and again significantly associated with chemotherapy administration (hazard ratio: 4.545, 95% CI: 1.178-17.539; Pâ¯=â¯.028). Thrombosis was found in 7 (1.70%) patients and occlusion in 13 (3.16%) cases. CONCLUSIONS AND IMPLICATIONS FOR NURSING PRACTICE: Choice of venous access is an interdisciplinary decision with emphasis on patient participation. In oncologic patients, our data suggests that the benefits of peripherally inserted central catheters regarding costs, invasiveness, and accessibility might be outweighed by the higher rate of complications associated with the device. This becomes even more important in a community care setting, where standardized handling procedures and patient education play a pivotal role in device safety.

PURPOSE OF REVIEW: This review summarizes the latest findings and recommendations about the characteristics, indications and use of peripheral and central long-term venous access devices.The various complications inherent in these devices are becoming better known, and their contributing factors determined, which could make it possible to reduce their incidence. RECENT FINDINGS: Some measures are integrated into recommendations for good practice, such as appropriate selection of devices, the preferential use of the thinnest catheters, and cyanoacrylate glue and dressings impregnated with chlorhexidine. SUMMARY: Improving understanding of the phenomena leading to infectious and thrombotic complications, as well as better knowing the differences between intravenous devices and their respective indications, should lead to improvement of in-hospital and out-of-hospital care.

BACKGROUND: Incidence of central venous catheter (CVC)-related thrombosis in critically ill patients remains ambiguous and its association with potential hazardous sequelae unknown. The primary aim of the study was to evaluate the epidemiology of CVC-related thrombosis; secondary aims were to assess the association of catheter-related thrombosis with catheter-related infection, pulmonary embolism and mortality. METHODS: This was a single-center, prospective observational study conducted at a tertiary intensive care unit (ICU) in the Netherlands. The study population consisted of CVC placements in adult ICU patients with a minimal indwelling time of 48 h. CVC-related thrombosis was diagnosed with ultrasonography. Primary outcomes were prevalence and incidence, incidence was reported as the number of cases per 1000 indwelling days. RESULTS: 173 CVCs in 147 patients were included. Median age of patients was 64.0 [IQR: 52.0, 72.0] and 71.1 % were male. Prevalence of thrombosis was 0.56 (95 % CI: 0.49, 0.63) and incidence per 1000 indwelling days was 65.7 (95 % CI: 59.0, 72.3). No association with catheter-related infection was found (p = 0.566). There was a significant association with pulmonary embolism (p = 0.022). All 173 CVCs were included in the survival analysis. Catheter-related thrombosis was associated with a lower 28-day mortality risk (hazard ratio: 0.39, 95 % CI: 0.17, 0.87). CONCLUSION: In critically ill patients, prevalence and incidence of catheter-related thrombosis were high. Catheter-related thrombosis was not associated with catheter-related infections, but was associated with pulmonary embolism and a decreased mortality risk.

BACKGROUND: Neurogenic bladder dysfunction is a major problem for spinal cord injury (SCI) patients not only due to the risk of serious complications but also because of the impact on quality of life. The main aim of this study is to compare the rate of urinary tract infection (UTI) associated with hydrophilic-coated catheters versus uncoated polyvinyl chloride (PVC) catheters among SCI patients presenting with functional neurogenic bladder sphincter disorders. METHODOLOGY: This was a retrospective cohort study from 2005 to 2020 including adult male or female patients who have an SCI at least more than 1 month ago with neurogenic bladder dysfunction and were using intermittent catheterization (single-use hydrophilic-coated or the standard-of-care polyvinyl chloride uncoated standard catheters) at least 3 times a day to maintain bladder emptying. RESULTS: A total of 1000 patients were selected and recruited through a stratified random sampling technique with 467 (47.60%) patients in the uncoated catheter arm and 524 (52.60%) in the coated catheter groups. The three outcome measures, namely: symptomatic UTI, Bacteriuria, and pyuria were significantly higher in the group using uncoated polyvinyl chloride (PVC) catheters compared to hydrophilic-coated catheters at the rate of 79.60% vs.46.60%, 81.10% vs. 64.69, and 53.57% versus 41.79% respectively. Males, elder patients, longer duration, and severity of SCI were associated with increased risk of symptomatic UTI. CONCLUSIONS: The results indicate a beneficial effect regarding clinical UTI when using hydrophilic-coated catheters in terms of fewer cases of symptomatic UTI. Bacteriuria is inevitable in patients with long-term catheterization, however, treatment should not be started unless the clinical symptoms exist. More attention should be given to the high-risk group for symptomatic UTIs.

Introduction. The Triveneto Peritoneal Dialysis (PD) Network aims to bring together doctors and nurses who deal with PD in a collaborative network in which to exchange mutual knowledge and optimize the use of this method of replacing renal function. A topic of particular interest was the management of peritoneal catheter exit-site infection, given the recent publication of the new guidelines of the International Society of Peritoneal Dialysis (ISPD). Materials and methods. The survey concerned the criteria for carrying out nasal swab and exit-site, management of exuberant granulation tissue "Proud Flesh", treatment of exit-site infection (ESI), use of silver dressings, the role of subcutaneous tunnel ultrasound and cuff shaving. Results. All PD centers in the North-East Italy area have joined the survey with at least one operator per centre. There was a wide variability between the indications for performing the exit-site swab. In the presence of ESI, the prevalent approach is that of oral systemic empiric therapy associated (20.0%) or less (28.9%) with topical therapy, and then adapting it in a targeted manner to the culture examination. Discussion. From the discussion of the survey emerged the importance of the ESI as an outcome indicator, which allows us to verify whether our clinical practice is in line with the reference standards. It is essential to know and base our activity on what is indicated in national and international guidelines and to document the events that occur in the patient population of each dialysis unit.

BACKGROUND: Ambulatory central line-associated bloodstream infections (CLABSIs) cause significant morbidity and mortality, especially in pediatric oncology. Few studies have had interventions directed toward caregivers managing central lines (CL) at home to reduce ambulatory CLABSI rates. We aimed to reduce and sustain our ambulatory CLABSI rate by 25% within 3 years of the start of a quality improvement intervention. PROCEDURE: Plan-do-study-act cycles were implemented beginning April 2016. The main intervention was a family-centered CL care skill development curriculum for external CLs. Training began upon hospital CL insertion, followed by an ambulatory teach-back program to achieve home caregiver CL care independence. Other changes included: standardizing ambulatory nurse CL care practice (audits, a train the nurse trainer process, and workshops for independent home care agencies); developing aids for trainers and caregivers; providing supplies for clean surfaces; wide dissemination of the program; and minimizing opportunities of CLABSI (e.g., standardizing timing of CL removal). The outcome measure was the ambulatory CLABSI rate (excluding mucosal barrier injury laboratory-confirmed bloodstream infection), compared pre intervention (January 2015 to March 2016) to post intervention, including 2 years of sustainability (April 2016 to June 2023), using statistical process control charts. We estimated the total number of CLABSI and associated healthcare charges prevented. RESULTS: The ambulatory CLABSI rate decreased by 52% from 0.25 to 0.12 per 1000 CL days post intervention, achieved within 27 months; 117 CLABSI were prevented, with $4.2 million hospital charges and 702 hospital days avoided. CONCLUSIONS: Focusing efforts on home caregivers CL care may lead to reduction in pediatric oncology ambulatory CLABSI rates.

BACKGROUND: Exit-site infection (ESI) is a common recurring complication in patients undergoing peritoneal dialysis (PD). Sucrose and povidone-iodine (SPI) mixtures, antimicrobial ointments that promote wound healing, have been used for the treatment of ulcers and burns, but their efficacy in exit-site care is still unclear. METHODS: This single-center retrospective observational study included patients who underwent PD between May 2010 and June 2022 and presented with episodes of ESI. Patients were divided into SPI and non-SPI groups and followed up from initial ESI onset until PD cessation, death, transfer to another facility, or June 2023. RESULTS: Among the 82 patients (mean age 62, [54-72] years), 23 were treated with SPI. The median follow-up duration was 39 months (range, 14-64), with an overall ESI incidence of 0.70 episodes per patient-year. Additionally, 43.1% of second and 25.6% of third ESI were caused by the same pathogen as the first. The log-rank test demonstrated significantly better second and third ESI-free survival in the SPI group than that in the non-SPI group (p < 0.01 and p < 0.01, respectively). In a Cox regression analysis, adjusting for potential confounders, SPI use was a significant predictor of decreased second and third ESI episodes (hazard ratio [HR], 0.22; 95% confidence interval [CI], 0.10-0.52 and HR, 0.22; 95%CI, 0.07-0.73, respectively). CONCLUSIONS: Our results showed that the use of SPI may be a promising option for preventing the incidence of ESI in patients with PD. TRIAL REGISTRATION: This study was approved by the Keio University School of Medicine Ethics Committee (approval number 20231078) on August 28, 2023. Retrospectively registered.

OBJECTIVES: To compare catheter-related outcomes of individuals who received a tunnelled femorally inserted central catheter (tFICC) with those who received a peripherally inserted central catheter (PICC) in the upper extremities. DESIGN: A propensity-score matched cohort study. SETTING: A 980-bed tertiary referral hospital in South West Sydney, Australia. PARTICIPANTS: In-patients referred to the hospital central venous access service for the insertion of a central venous access device. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome of interest was the incidence of all-cause catheter failure. Secondary outcomes included the rates of catheters removed because of suspected or confirmed catheter-associated infection, catheter dwell and confirmed upper or lower extremity deep vein thrombosis (DVT). RESULTS: The overall rate of all-cause catheter failure in the matched tFICC and PICC cohort was 2.4/1000 catheter days (95% CI 1.1 to 4.4) and 3.0/1000 catheter days (95% CI 2.3 to 3.9), respectively, and when compared, no difference was observed (difference -0.63/1000 catheter days, 95% CI -2.32 to 1.06). We found no differences in catheter dwell (mean difference of 14.2 days, 95% CI -6.6 to 35.0, p=0.910); or in the cumulative probability of failure between the two groups within the first month of dwell (p=0.358). No significant differences were observed in the rate of catheters requiring removal for confirmed central line-associated bloodstream infection (difference 0.13/1000 catheter day, 95% CI -0.36 to 0.63, p=0.896). Similarly, no significant differences were found between the groups for confirmed catheter-related DVT (difference -0.11 per 1000 catheter days, 95% CI -0.26 to 0.04, p=1.00). CONCLUSION: There were no differences in catheter-related outcomes between the matched cohort of tFICC and PICC patients, suggesting that tFICCs are a possible alternative for vascular access when the veins of the upper extremities or thoracic region are not viable for catheterisation.

OBJECTIVE: Despite the effort to increase the proportion of patients starting dialysis on native accesses, many of them are still dialyzed on tunnelled catheter. Catheter-related complications are often serious and responsible for re-hospital admission, high morbidity and mortality. Several multicenter trials have reported results in the use of tunnelled dialysis catheter (TDC). However, few single-center studies have been published to verify the outcome from real-world experience. This study presents our center's experience in managing such patients in the context of relevant literature. METHODS: Demographics and operative data were retrospectively collected from medical charts. A prospective follow-up was performed to investigate complications, number of re-hospitalizations and mortality. Kaplan-Meier estimate was used to evaluate catheter primary patency and patients' overall survival. RESULTS: Among a total 298 haemodialysis accesses interventions, 105 patients (56 men, 53.3% and 49 women, 46.7%) with a median age of 65 years (range 32-88 years) were included in the study. All insertions were successful with an optimal blood flow achieved during the first session of dialysis in all cases. A catheter-related complication was detected in 33.3% (n=35) patients (48.6% infections; 28.6% TDC dysfunction; 14.3% local complications; 5.7% accidental catheter retractions; 2.8% catheter migrations). At a median follow-up of 10.5±8.5 months, a total of 85 patients (80.9%) was re-hospitalized, in 28 cases (26.7%) for a catheter-related cause. The median catheter patency rate was 122 days. At the last follow-up, 39 patients (37.1%) were still dialyzed on catheter, 30(28.6%) were dialyzed on an arteriovenous fistula and 7(6.7%) received a kidney transplantation. Two patients (2%) were transferred to peritoneal dialysis and two patients (2%) recover from renal insufficiency. Mortality rate was 23.8% (25 patients). Causes of death were myocardial infarction (n=13, 52%), sepsis (n=9, 36%); one patient (4%) died from pneumonia, one (4%) from uremic encephalopathy and one (4%) from massive hematemesis. CONCLUSION: TDCs may represent the only possible access in some patients, however they are burned with a high rate of complications, re-hospital admission and mortality. Results from this institutional experience are in line with previously published literature data in terms of morbidity and mortality. The present results reiterate once more that TDC must be regarded as a temporary solution while permanent access creation should be prioritized. Strict surveillance should be held in patients having TDC for the early identification of complications allowing the prompt treatment and modifying the catheter insertion site whenever needed.

In patients on peritoneal dialysis, the cutaneous emergency (exit-site) represents a potential access route to the peritoneum; consequently, it can become a site for microbial infections. These infections, initially localized to the exit-site, may spread to the peritoneum causing peritonitis, which is the most common cause of drop-out from peritoneal dialysis and transition to hemodialysis. Peritoneal catheters have dacron caps which have the function of counteracting the traction of the catheter itself and at the same time acting as a barrier for microorganisms, preventing the spread towards the peritoneum. Despite this, the same dacron cap can represent a sort of nest for microorganisms to colonize and, with the formation of a biofilm that facilitates their proliferation, make the same organisms impervious to antibiotic therapy and even resistance to them. The most effective tool for monitoring the health status of the exit-site is represented by the objective examination. This examination, through the use of well-defined scales, helps to provide a pathological score of the exit, facilitating the implementation of necessary precautions. In the presence of recurrent exit-site infections, from both Gram positive and Gram negative bacteria, minimally invasive surgical therapy is a valid approach to break this vicious circle. It helps avoid subjecting the patient to the removal of the peritoneal catheter, temporary transition to hemodialysis with the insertion of a central venous catheter, and subsequent repositioning of another peritoneal catheter. We propose the case of a recurrent Staphylococcus Aureus infection resolved after cuff shaving of the exit-site.

OBJECTIVE: To provide theoretical basis for prevention of a Dacron-cuffed catheter related infection (CRI), the risk factors of CRI in hemodialysis patients were systematically evaluated. METHODS: Eight databases, including PubMed, Cochrane library, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Database (CBM), Wanfang Database and Chinese Scientific Journal Database (VIP), were searched to screen out literatures related to the risk factors of long-term indwelling a Dacron-cuffed CRI in hemodialysis. Meta-analysis of risk factors for a Dacron-cuffed CRI in hemodialysis and publication bias test were performed using RevMan 5.4 software. RESULTS: After screening, 13 literatures involving a Dacron-cuffed CRI were included, with a total of 625 patients, and the infection rate was 11.7%. The combined OR value and 95% confidence interval (CI) of all factors were: Combined with Diabetes (1.94, 1.51 ~ 2.50), Hb (1.82, 1.35 ~ 2.44), age (2.38, 1.06 ~ 5.34), catheter indwelling time (1.79, 1.21 ~ 2.66), serum albumin (2.26, 1.25 ~ 4.08), catheter indwelling site (3.29, 1.74 ~ 6.23) and the number of tube placement (5.40, 2.65 ~ 11.02). CONCLUSIONS: The main risk factors for a Dacron-cuffed CRI in hemodialysis were combined with diabetes, hemoglobin level, age, catheter indwelling time, serum albumin level, femoral vein catheter indwelling and catheterization times. In other words, hemodialysis patients are at higher risk of CRI if they have diabetes, or if they have a lower hemoglobin level, or if they are older, or if they have a longer duration of catheterization, or if they have a lower serum albumin level, or if they have a femoral vein catheter, or if they have more catheters.

BACKGROUND: Tunneled central venous catheters (CVCs) are the cornerstone of modern oncologic practice. Establishing best practices for catheter management in children with cancer is essential to optimize care, but few guidelines exist to guide placement and management. OBJECTIVES: To address four questions: 1) Does catheter composition influence the incidence of complications; 2) Is there a platelet count below which catheter placement poses an increased risk of complications; 3) Is there an absolute neutrophil count (ANC) below which catheter placement poses an increased risk of complications; and 4) Are there best practices for the management of a central line associated bloodstream infection (CLABSI)? METHODS: Data Sources: English language articles in Ovid Medline, PubMed, Embase, Web of Science, and Cochrane Databases. STUDY SELECTION: Independently performed by 2 reviewers, disagreements resolved by a third reviewer. DATA EXTRACTION: Performed by 4 reviewers on forms designed by consensus, quality assessed by GRADE methodology. RESULTS: Data were extracted from 110 manuscripts. There was no significant difference in fracture rate, venous thrombosis, catheter occlusion or infection by catheter composition. Thrombocytopenia with minimum thresholds of 30,000-50,000 platelets/mcl was not associated with major hematoma. Limited evidence suggests a platelet count <30,000/mcL was associated with small increased risk of hematoma. While few studies found a significant increase in CLABSI in CVCs placed in neutropenic patients with ANC<500Kcells/dl, meta-analysis suggests a small increase in this population. Catheter removal remains recommended in complicated or persistent infections. Limited evidence supports antibiotic, ethanol, or hydrochloric lock therapy in definitive catheter salvage. No high-quality data were available to answer any of the proposed questions. CONCLUSIONS: Although over 15,000 tunneled catheters are placed annually in North America into children with cancer, there is a paucity of evidence to guide practice, suggesting multiple opportunities to improve care. LEVEL OF EVIDENCE: III. This study was registered as PROSPERO 2019 CRD42019124077.

BACKGROUND: This retrospective study assesses the influence of tunneled hemodialysis catheter tip location and lateralization on catheter-related complications, including dysfunction and catheter-related bloodstream infection. METHODS: Using data from 162 patients who underwent catheter placement between January 2017 and December 2020, postoperative chest X-rays and clinical records were reviewed. Outcomes were assessed based on catheter removal duration and complication incidence. RESULTS: Out of 177 catheter placements, 56 (32%) patients experienced complications during an average 530-day follow-up. Catheters placed in the superior vena cava (SVC) exhibited more severe complications with shorter dwell times compared with those in the pericavoatrial junction (pCAJ) or right atrium (RA). Moreover, complication rates were significantly higher (P < 0.01) in the SVC (1.91 per 1000 catheter days) compared with the pCAJ (0.54) or RA (0.47). Lateralization (right or left internal jugular vein) did not significantly affect the complication rates (0.60 vs. 0.58; P = 0.90). However, in subgroup analysis, a significantly higher complication rate was observed for catheters with tips inserted from the left side into the SVC than for those inserted from the right side (6.6 vs. 1.5; P < 0.01). CONCLUSIONS: Catheters with tips in the SVC exhibited more severe complications than those in the pCAJ or RA, with left-side insertion of SVC-tipped catheters resulting in significantly higher complication rates compared with right-side insertion. These findings highlight the importance of optimal catheter tip positioning in long-term hemodialysis care to minimize complications and enhance patient outcomes.

BACKGROUND: It remains unclear whether peripherally inserted central catheters (PICCs) are superior to central venous catheters (CVCs); therefore, we compared post-implantation complications between CVC and PICC groups. RESEARCH DESIGN AND METHODS: Patients who received CVCs or PICCs between April 2010 and March 2018 were identified from the Diagnosis Procedure Combination database, a national inpatient database in Japan. The outcomes of interest included catheter infection, pulmonary embolism, deep vein thrombosis, and phlebitis. Propensity score overlap weighting was used to balance patient backgrounds. Outcomes were compared using logistic regression analyses. RESULTS: We identified 164,185 eligible patients, including 161,605 (98.4%) and 2,580 (1.6%) in the CVC and PICC groups, respectively. The PICC group was more likely to have overall complications (odds ratio [OR], 1.70; 95% confidence interval [CI], 1.32-2.19), pulmonary embolism (OR, 2.32; 95% CI, 1.38-3.89), deep vein thrombosis (OR, 1.86; 95% CI, 1.16-2.99), and phlebitis (OR, 1.72; 95% CI, 1.27-2.32) than the CVC group. There was no significant intergroup difference in catheter infection (OR, 1.09; 95% CI, 0.39-3.04). CONCLUSIONS: Patients with PICCs had a significantly greater incidence of complications than did those with CVCs. Further research is necessary to explore the factors contributing to these complications.

BACKGROUND: Central venous catheter (CVC)-related complications remain a significant cause of morbidity in pediatric hematology-oncology. We prospectively surveyed the incidence of CVC-related complications in children with hematologic-oncologic diseases. PROCEDURE: Five-hundred-eighty-one CVCs were inserted in 421 patients from January 2010 to June 2022 (153,731 CVC days observation; follow-up data up to December 31, 2022). RESULTS: Overall, 671 complications were recorded (4.365/1000 CVC days): 49.7% malfunctions (1.88/1000 CVC days, 4.8% of CVC early removals), 23.9% bacteremia (0.90/1000, 15.1%), 19.6% mechanical complications (0.74/1000, 70.2%), 20.1% localized infections (0.76/1000, 17.1%), 0.5% thrombosis (0.02/1000, 33.3%). At multivariate analysis, risk factors for malfunction were Broviac-Hickman type of CVC (hazard ratio [HR] 2.5) or Port-a-cath (HR 3.4) or Proline (HR 4.3), p < .0001; for bacteremia double-lumen CVC (HR 3.2, p < .0001); for mechanical complications age at CVC insertion under median (HR 4.5, p < .0001) and Broviac-Hickman (HR 1.6) or Proline (HR 2.7), p = .01; finally for localized infections Broviac-Hickman (HR 2.9) or Proline (HR 4.4), p = .0001. The 2-year cumulative incidence of premature removal was 23.5%, and risk factors were age at CVC insertion under median (HR 2.4, p < .0001), Broviac-Hickman (HR 2.3) or Proline (HR 4.2), p < .0001. CONCLUSIONS: Premature removal occurs in approximately 20%-25% of long-term CVCs. A surveillance program has a fundamental role in identifying the risk factors for CVC complications and the areas of intervention to improve CVC management.
