A meta-analysis of risk factors for a Dacron-cuffed catheter related infection in hemodialysis.

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.

Central venous access device terminologies, complications, and reason for removal in oncology: a scoping review.

BACKGROUND: Lack of agreed terminology and definitions in healthcare compromises communication, patient safety, optimal management of adverse events, and research progress. The purpose of this scoping review was to understand the terminologies used to describe central venous access devices (CVADs), associated complications and reasons for premature removal in people undergoing cancer treatment. It also sought to identify the definitional sources for complications and premature removal reasons. The objective was to map language and descriptions used and to explore opportunities for standardisation. METHODS: A systematic search of MedLine, PubMed, Cochrane, CINAHL Complete and Embase databases was performed. Eligibility criteria included, but were not limited to, adult patients with cancer, and studies published between 2017 and 2022. Articles were screened and data extracted in Covidence. Data charting included study characteristics and detailed information on CVADs including terminologies and definitional sources for complications and premature removal reasons. Descriptive statistics, tables and bar graphs were used to summarise charted data. RESULTS: From a total of 2363 potentially eligible studies, 292 were included in the review. Most were observational studies (n = 174/60%). A total of 213 unique descriptors were used to refer to CVADs, with all reasons for premature CVAD removal defined in 84 (44%) of the 193 studies only, and complications defined in 56 (57%) of the 292 studies. Where available, definitions were author-derived and/or from national resources and/or other published studies. CONCLUSION: Substantial variation in CVAD terminology and a lack of standard definitions for associated complications and premature removal reasons was identified. This scoping review demonstrates the need to standardise CVAD nomenclature to enhance communication between healthcare professionals as patients undergoing cancer treatment transition between acute and long-term care, to enhance patient safety and rigor of research protocols, and improve the capacity for data sharing.

On the way to the azygos vein: a road of return rather than ruined.

BACKGROUND: The malposition of central venous catheters (CVCs) may lead to vascular damage, perforation, and even mediastinal injury. The malposition of CVC from the right subclavian vein into the azygos vein is extremely rare. Here, we report a patient with CVC malposition into the azygos vein via the right subclavian vein. We conduct a comprehensive review of the anatomical structure of the azygos vein and the manifestations associated with azygos vein malposition. Additionally, we explore the resolution of repositioning the catheter into the superior vena cava by carefully withdrawing a specific length of the catheter. CASE PRESENTATION: A 79-year-old female presented to our department with symptoms of complete intestinal obstruction. A double-lumen CVC was inserted via the right subclavian vein to facilitate total parenteral nutrition. Due to the slow onset of sedative medications during surgery, the anesthetist erroneously believed that the CVC had penetrated the superior vena cava, leading to the premature removal of the CVC. Postoperative contrast-enhanced computed tomography of the chest confirmed that the central venous catheter had not penetrated the superior vena cava but malpositioned into the azygos vein. The patient was discharged 15 days after surgery without any complications. CONCLUSIONS: CVC malposition into the azygos vein is extremely rare. Clinical practitioners should be vigilant regarding this form of catheter misplacement. Ensuring the accurate positioning of the CVC before each infusion is crucial. Utilizing chest X-rays in both frontal and lateral views, as well as chest computed tomography, can aid in confirming the presence of catheter misplacement.

Air embolism caused by peripheral superficial vein catheterization: A case report.

BACKGROUND: Air embolization is usually an iatrogenic complication that can occur in both veins and arteries. Intravenous air embolization is mainly associated with large central vein catheters and mechanical ventilation. A 59-year-old woman was sent to our hospital with spontaneous cerebral hemorrhage and treated conservatively with a left forearm peripheral venous catheter infusion drug. After 48 hours, the patient's oxygen saturation decreased to 92 % with snoring breathing. Computer tomography of the head and chest revealed scattered gas in the right subclavian, the right edge of the sternum, the superior vena cava, and the leading edge of the heart shadow. METHODS: She was sent to the intensive care unit for high-flow oxygen inhalation and left-side reclining instantly. As the patient was at an acute stage of cerebral hemorrhage and did not take the Trendelenburg position. RESULTS: The computed tomography (CT) scan after 24 hours shows that the air embolism subsides. CONCLUSION SUBSECTIONS: Air embolism can occur in any clinical scenario, suggesting that medical staff should enhance the ability to identify and deal with air embolism. For similar cases in clinical practice, air embolism can be considered.

Surveillance of catheter-associated bloodstream infections: development and validation of a fully automated algorithm.

BACKGROUND: Most surveillance systems for catheter-related bloodstream infections (CRBSI) and central line-associated bloodstream infections (CLABSI) are based on manual chart review. Our objective was to validate a fully automated algorithm for CRBSI and CLABSI surveillance in intensive care units (ICU). METHODS: We developed a fully automated algorithm to detect CRBSI, CLABSI and ICU-onset bloodstream infections (ICU-BSI) in patients admitted to the ICU of a tertiary care hospital in Switzerland. The parameters included in the algorithm were based on a recently performed systematic review. Structured data on demographics, administrative data, central vascular catheter and microbiological results (blood cultures and other clinical cultures) obtained from the hospital's data warehouse were processed by the algorithm. Validation for CRBSI was performed by comparing results with prospective manual BSI surveillance data over a 6-year period. CLABSI were retrospectively assessed over a 2-year period. RESULTS: From January 2016 to December 2021, 854 positive blood cultures were identified in 346 ICU patients. The median age was 61.7 years [IQR 50-70]; 205 (24%) positive samples were collected from female patients. The algorithm detected 5 CRBSI, 109 CLABSI and 280 ICU-BSI. The overall CRBSI and CLABSI incidence rates determined by automated surveillance for the period 2016 to 2021 were 0.18/1000 catheter-days (95% CI 0.06-0.41) and 3.86/1000 catheter days (95% CI: 3.17-4.65). The sensitivity, specificity, positive predictive and negative predictive values of the algorithm for CRBSI, were 83% (95% CI 43.7-96.9), 100% (95% CI 99.5-100), 100% (95% CI 56.5-100), and 99.9% (95% CI 99.2-100), respectively. One CRBSI was misclassified as an ICU-BSI by the algorithm because the same bacterium was identified in the blood culture and in a lower respiratory tract specimen. Manual review of CLABSI from January 2020 to December 2021 (n = 51) did not identify any errors in the algorithm. CONCLUSIONS: A fully automated algorithm for CRBSI and CLABSI detection in critically-ill patients using only structured data provided valid results. The next step will be to assess the feasibility and external validity of implementing it in several hospitals with different electronic health record systems.

Beyond traditional venous access: Midline catheter use in pediatric apheresis.

The objective of this study was to assess the use of midline catheters as venous access for apheresis procedures in pediatric patients. A retrospective analysis of medical records was conducted from September 2019 to June 2022 to evaluate the safety and efficacy of midline catheters for therapeutic pediatric apheresis. During the study period, a total of 121 procedures were inserted in 22 unique patients. The age of the subjects ranged from 2.7 to 21 years. The blood flow rates achieved with midline catheters met or exceeded the recommended rates for apheresis in children (40 mL/min), by the Wilcoxon signed-rank test (p < 0.0001). There was one episode of catheter-related thrombosis, but no cases of bloodstream infection or catheter dislodgement were reported. In conclusion, this study supports the use of midline catheters as a safe and effective alternative for venous access during therapeutic and donor apheresis procedures in pediatric patients.

Application of pocket-first technique for implantation of totally implantable venous access ports.

BACKGROUND: While vascular puncture is always performed before making port pocket in the implantation of totally implantable venous access ports (TIVAP), some surgeons preferred to make port pocket first. This study seeks to verify the safety and feasibility for the pocket-first technique. METHODS: The study retrospectively reviewed 447 patients who undergone TIVAP implantation from July 2017 to November 2022. All the patients were divided into two groups based on vascular puncture first or making port pocket first. The general information, operation information and post-operative complications were reviewed and analyzed. RESULTS: All the operations were performed successfully. No difference was observed in the sex, age, height, weight, BMI, port location and total complication rate between the two groups. The operation time of the Puncture Group and the Pocket Group were 46.9 ± 22.4 min and 33.8 ± 13.6 min ( P<0.00001 ). In the patients of SCV approach, the operation time between the two groups were 37.4 ± 14.8 min and 33.5 ± 10.9 min ( P<0.05 ). Multivariate analysis showed the variable BMI and first procedure were independent prognostic factors for operation time. In the cases using SCV/AxV approach the variable first procedure was the only independent prognostic factor for operation time (P = 0.002). CONCLUSIONS: The pocket-first technique can be considered as a safe, feasible and convenient technique for TIVAP implantation. The time consuming is significantly shortened compared with the puncture-first technique and this advantage may be more obvious when using SCV/AxV approach.

Systematic culture of central catheters and infections related to catheters in a neonatal intensive care unit: an observational study.

Systematic culture of the tip of central lines is performed in many neonatal intensive care units (NICUs) to guide any subsequent antibiotic therapy. The clinical relevance of this procedure is debated, given the significant bacterial contamination during its removal. We aimed to describe infections related to catheters and assess the usefulness of central catheter systematic cultures for probabilistic antibiotic therapy in cases of suspicion of catheter-related infections in a NICU. A retrospective study in a NICU included all newborn patients hospitalized with a central catheter, between January 2018, and June 2019. The main outcome measures were bacterial catheter colonization, catheter-related infection rate, and simulation-based approach to antibiotic prescription. Three hundred and seventy-five newborns, with 634 central catheters were included. There were 273 (43%) catheters that were colonized by at least one microorganism. There were 183 cases of suspected sepsis, with 31 infections definitively related to the catheter. In our simulation antibiotic prescription approach, there was no significant difference in terms of the efficacy toward the microorganism(s) involved between the probabilistic antibiotic therapies proposed by the experts and those ultimately prescribed. Performing a catheter culture only if catheter-related infection is suspected could be an alternative to routine screening.

Risk factors of central catheter bloodstream infections in intensive care units: A systematic review and meta-analysis.

BACKGROUND: Central catheter bloodstream infections (CRBSI) is a major cause of healthcare-associated infections. However, few factors are generally accepted and some studies have conflicting finding about some factors, possibly caused by limitation associated with an individual study. This study was to identify risk factors for CRBSI in intensive care units. METHODS: We searched the PubMed, Cochrane Library, Web of science and EMBASE databases and the 4 top Chinese-language databases, including WanFang data, China National Knowledge Infrastructure (CNKI), and Chinese Science and Technology Journal Database (VIP), China Biology Medicine disc (CBM) as of July 2023. Case control and cohort studies were included. Two authors independently screened the literature and evaluated the quality of the studies using the Newcastle-Ottawa scale (NOS). The pooled effect size was estimated using the odds ratio (OR), and the corresponding 95% confidence interval (CI) was calculated. The Cochrane Q (χ2) and I2 tests were used to assess heterogeneity among studies, and each risk factor was tested for its robustness using fixed- or random-effects models. FINDINGS: A total of 32 studies enrolled, among which eleven factors were identified, they were divided into two categories: modifiable and unmodifiable factors. Modifiable factors: duration of catheterization (≥ 5d) (OR: 2.07, 95%CI: 1.41-3.03), duration of catheterization (≥ 7d) (OR: 3.62, 95%CI: 2.65-4.97), duration of catheterization (≥ 14d)(OR: 4.85, 95%CI: 3.35-7.01), total parenteral nutrition (OR: 2.27,95%CI: 1.56-3.29), use of multiple-lumen catheters(OR: 3.41, 95%CI: 2.27-5.11), times of tube indwelling (OR: 3.50, 95%CI: 2.93-4.17), length of ICU stay (OR: 4.05, 95%CI: 2.41-6.80), the position of indwelling(OR: 2.41, 95%CI: 2.03-2.85); Unmodifiable factors: APACHEII scores (OR: 1.84, 95%CI: 1.54-2.20), Age≥ 60 years old (OR: 2.19, 95%CI: 1.76-2.73), the extensive use of antibiotic (OR: 3.54, 95%CI: 1.65-7.61), Diabetes mellitus (OR: 3.06, 95%CI: 2.56-3.66), Immunosuppression (OR: 2.87, 95%CI: 2.08-3.95). CONCLUSIONS: Effective interventions targeting the above modifiable factors may reduce the risk of developing CRBSI in ICU and improve the clinical outcome of patients. Further prospective studies are needed to confirm these findings.

[Real-time localization for port-implanted catheter tip by echocardiographic guidance].

The clinical data of 23 patients undergoing real-time echocardiography-guided infusion port implantation in the Breast Center of Tsinghua Changgung Hospital in Beijing from January to July 2021 were analyzed. The length of catheter insertion L1 was initially estimated using surface measurement method in all patients. Intraoperatively, transthoracic echocardiography was applied using the parasternal four-chamber view to visualize the catheter image within the right atrium, and the length of catheter insertion L2 was recorded under the guidance of echocardiography. Postoperatively, chest radiographs were taken in the upright position to observe the position of the catheter tip. According to chest CT scans, the ideal length (L) for catheter tip placement was calculated when it was located at the junction of superior vena cava and right atrium. Bland-Altman scatter plot analysis and linear regression fitting test were used on L1 and L2 respectively with L to evaluate the consistency. A total of 23 patients were included in this study, among which one case of left breast cancer patient undergoing breast-conserving surgery had difficulty in identifying the catheter tip position due to residual pleural effusion obscuring the imaging of the cardiac apex four-chamber view. In 22 patients, the results of intraoperative ultrasound imaging were good, including 1 case of catheter ectopic to azygos vein, and 21 cases of right atrial catheter could be detected by ultrasound. Statistical analysis showed that there was a good consistency between L1 and L, L2 and L, and the difference between them was d=0.28 cm (95%CI:-1.76-2.31 cm) and d=0.20 cm(95%CI:-0.84-1.23 cm), respectively, with no statistical significance (P>0.05). In the linear regression model, L2 and L had a higher fit than L1, and the difference was statistically significant (R²=0.954, P<0.001). This study found that real-time echocardiographic localization technique can be applied in adult port surgery to replace X-ray-guided real-time catheter tip detection and adjustment to the optimal position.

Impact of insertion into the left internal jugular vein in chemoport-associated infections: a retrospective single-center study of 1690 cases.

We analyzed chemoport insertion procedures to evaluate infectious morbidity and factors causing infection. This single-center retrospective study included 1690 cases of chemoport implantation between January 2017 and December 2020. Overall, chemoports were inserted in 1582 patients. The average duration of chemoport use was 481 days (range 1-1794, median 309). Infections occurred in 80 cases (4.7%), with 0.098 per 1000 catheter-days. Among the 80 cases in which chemoports were removed because of suspected infection, bacteria were identified in 48 (60%). Significantly more cases of left internal jugular vein punctures were noted in the infected group (15 [18.8%] vs. 147 [9.1%]; p = 0.004). Pulmonary embolism was significantly different between the infection groups (3 [3.8%] vs. 19 (1.2%), p = 0.048). The hazard ratio was 2.259 (95% confidence interval [CI] 1.288-3.962) for the left internal jugular vein, 3.393 (95% CI 1.069-10.765) for pulmonary embolism, and 0.488 (95% CI 0.244-0.977) for chronic obstructive pulmonary disease. Using the right internal jugular vein rather than the left internal jugular vein when performing chemoport insertion might reduce subsequent infections.

[Mid-term analysis of prospective cohort study of rivaroxaban in preventing CRT in breast cancer].

Objective: To explore the efficacy and safety of Rivaroxaban in preventing catheter related thrombosis (CRT) in patients with breast cancer who are undergoing central venous catheter chemotherapy, and provide basis for making standardized prevention and treatment strategies. Methods: In this research, a prospective cohort study was adopted, and breast cancer patients who received central venous catheter chemotherapy in Sanhuan Cancer Hospital during September 2020 to March 2022 were selected as a treatment group to take the rivaroxaban anticoagulation therapy with 10 mg.po.qd for one month. The control group got no preventive anticoagulation therapy. Vascular ultrasound examination was taken to confirm the occurrence of CRT, and a chi-square test was done for comparison the disparity between the groups. Logistic regression was applied to analyze the univariate and multivariate factors for the formation of CRT. Results: In the research, a total of 235 patients were selected, and there were a total of 19 035 days of catheterization with 81 days of catheterization on average. While in the control group, the incidence of CRT was 28.0% (33/118), the incidence of CRT in the treatment group was 20.5% (24/117), the difference was no significant (P=0.183). Subgroup analysis results showed that the peripherally inserted central catheter (PICC) was performed in 165 cases with the CRT incidence of 18.2% (30/165) and thrombosis was mostly seen around axillary vein, accounting for 63.3%. Subclavian vein catheterization was performed in 63 cases with the CRT incidence of 39.7% (25/63), and thrombosis was mostly seen around subclavian vein, accounting for 88.0% (22/25). Implantable venous access port was implanted in 7 cases around subclavian vein and internal jugular vein with the CRT incidence of 28.6% (2/7). The patients who developed CRT within 30 days after catheterization accounted for 54.4% (31/57), 22.8% (13/57) in a period during 30 days and 60 days) and 22.8% (13/57) in a period during 60 days and 180 days). The diagnosed CRT patients had been treated with rivaroxaban 15 mg.bid.po for 3 months. During the 3 months, 100.0% of the thrombosis waned, 71.9% (41/57) of the thrombosis waned within 30 days, 19.3% (11/57) in a period during 30 and 60days and 8.8% (5/57) in a period during 60 days and 90 days. Univariate and multivariate analysis indicated that the risk of CRT in subclavian vein catheterization was higher than that in PICC, respectively (OR=2.898, 95% CI:1.386-6.056 P=0.005), and the type of catheterization was an independent factor for the formation of thrombosis. Safety analysis result showed that in the prevention of CRT, rivaroxaban treatment did not induce drug-related bleeding, liver function damage, bone marrow suppression or any other side effects. While CRT diagnosed patients were treated with anticoagulation, they kept the central venous catheter, and the infusion was smooth. These patients all finished the anti-tumor treatment as planned, and no abnormalities like new thrombosis or pulmonary embolism were observed. Conclusions: In the mid-term analysis, the proportion of Rivaroxaban in preventing anticoagulant CRT decreases, but it don't reach statistical significance. The sample size should be further increased for observation. Rivaroxaban is proved effective and very safe in the treatment of CRT, and does not affect the concurrent chemotherapy. Medical personnel should carry out the policy of "early prevention, early detection and early treatment" for CRT so as to improve the patients' quality of life.

Is ultrasound guidance necessary to avoid complications in the implantation of venous access ports?

BACKGROUND: The aim of this study was to present demographic information of patients undergoing totally implantable venous access port (TIVAP) implantation and to investigate the rates of early and late complications, assessing the benefits of performing the procedure underUS guidance. METHODS: From May 2018 to December 2023, the outcomes of a total of 537 TIVAP implantation procedures were analyzed retrospectively. Data of the surgeons' experiences for both puncture methods (anatomical landmarks and ultrasound guidance) are presented in the study. RESULTS: The average age of the patients was 53.1±11.9 years, and 261 (48.6%) were female. The right subclavian vein was the preferred insertion site. Fourteen patients developed early complications and 11 developed late complications. Arterial puncture was the most common early complication, while catheter-related infection was the most common late complication. The age, sex, and body mass index of the patients were not independent risk factors for developing complications. Early complications increased as the number of puncture attempts did (p=0.034) and developed significantly less when ultrasound guidance was used during insertion (p=0.011). CONCLUSION: The risk of developing complications was not affected by patient's age or sex. In addition, body mass index was not shown to be an independent risk factor for patients developing complications. It may be concluded from the study that early complications in particular can be reduced with ultrasound-guided implantation.

Analysis and risk factors of deep vein catheterization-related bloodstream infections in neonates.

To investigate the incidence, risk factors, and pathogenic characteristics of catheter-related bloodstream infection caused by peripherally inserted central venous catheter in neonates, and to provide references for reducing the infection rate of peripherally inserted central venous catheter. The clinical data of 680 neonates who underwent peripherally inserted central catheter (PICC) in the neonatal intensive care unit from June 2020 to June 2023 were retrospectively analyzed. The risk factors and independent risk factors of catheter-related bloodstream infection caused by PICC were determined by univariate and multivariate analysis, respectively. Catheter-related bloodstream infection occurred in 38 of 680 neonates who underwent PICC. The infection rate was 4.74%. The proportions of fungi, gram-positive bacteria, and gram-negative bacteria were 42.11%, 36.84%, and 21.05%, respectively. Candida parapsilosis was the main fungus (18.42%), coagulase negative Staphylococcus was the main gram-positive bacteria (23.68%), and Klebsiella pneumoniae and Escherichia coli were the main gram-negative bacteria (7.89%). Univariate analysis showed that gestational age ≤32 weeks, birth weight ≤1500 g, congenital diseases, nutritional support, catheterization time, 5-minute APGAR score ≤7, and neonatal respiratory distress syndrome were associated with catheter-related bloodstream infection caused by PICC. Multivariate analysis showed that premature delivery, low birth weight, parenteral nutrition, long catheterization time, and 5-minute APGAR score ≤7 were associated with catheter-related bloodstream infection caused by PICC. Among the pathogens detected, there were 6 cases of K pneumoniae, 5 cases of coagulase negative staphylococci, and 2 cases of fungi. Low birth weight, premature delivery, off-site nutrition, long catheterization time, and 5-minute APGAR score ≤7 are independent risk factors for catheter-related bloodstream infection in neonates with peripherally inserted central venous catheters. The pathogenic bacteria are fungi and multidrug-resistant bacteria.

A New Equation to Estimate Peripherally Inserted Central Catheter Length.

Background and Objectives: Peripherally inserted central catheter (PICC) placement plays an important role in clinical practice. This study aimed to provide an equation for the proper estimation of catheter length in cases of PICC placement without imaging guidance in relation to patient height, weight, sex, and age. Materials and Methods: For 1137 PICC placement cases in both arm veins of 954 patients at a single center, the elbow crease to the cavoatrial junction length (ECL) was calculated as follows: ECL = (PICC length) + (distance from the elbow crease to the puncture site). We analyzed the relationship between ECL and patient characteristics and suggested a new equation for ECL based on height, weight, sex, and age. Results: The average ECL was 48.0 ± 2.4 cm in the right side and 51.0 ± 3.0 cm in the left side. ECL in the right arm was significantly correlated with patient height, sex, and age, whereas the ECL in the left arm was additionally significantly correlated with patient weight. The ECL (cm) prediction model was as follows: right ECL = 26.32 + 1.33 × (female = 1, male = 2) - 0.02 × age (years) + 0.13 × height (cm); left ECL = 22.09 + 1.28 × (female = 1, male = 2) + 0.02 × age (years) + 0.14 × height (cm) + 0.042 × weight (kg). Conclusions: The appropriate PICC length was predicted based on the patient's height, weight, sex, and age. The equations in our study can help predict the optimal catheter length and can be automatically calculated using computerized patient information for bedside procedures in PICC.

Cancer patients' experience with implanted venous ports: A qualitative descriptive study.

AIM: The aim of this study was to explore the experiences of cancer patients regarding venous access ports. BACKGROUND: The utilization of intravenous access ports for administering chemotherapy drugs is on the rise. Understanding patients' experiences with these devices can provide valuable insights for nursing managers and nurses. METHODS: A conventional qualitative content analysis approach was employed to explore the experiences of 14 patients who had venous access ports. The participants were selected from patients admitted to the oncology ward of a hospital affiliated with Kermanshah University of Medical Sciences. A purposive sampling method was used for participant selection. Semi-structured in-depth interviews were conducted as the data collection tool. MaxQda-10 software was utilized for data management. RESULTS: The data analysis yielded three main categories and ten sub-categories. The categories consisted of positive aspects of venous access ports, negative aspects of venous access ports, and barriers to accepting venous access ports. CONCLUSIONS: The participants highlighted both the positive and negative aspects of venous access ports, while also identifying insufficient knowledge and "fear and anxiety" as barriers to accepting these devices. Providing essential training and offering psychological support to newly hospitalized cancer patients could prove beneficial in this regard.

Catheter salvage from central line-related bloodstream infections in pediatric intestinal failure.

OBJECTIVES: Patients with intestinal failure require central venous access which puts them at risk for central line-associated bloodstream infections (CLABSI). Maintaining vascular patency is critical for this population to receive nutrition support. When CLABSIs occur line salvage can help maintain vascular access. The aim of this study is to assess factors associated with safe and successful central venous catheter salvage. METHODS: Retrospective cohort study of patients with intestinal failure at two tertiary care institutions between 2012 and 2020. The study examined the rates of attempted salvage, factors associated with successful salvage, and complications associated with salvage attempts. RESULTS: Over the study period, 76 patients with intestinal failure were include while central venous access was in place. There were a total of 94 CLABSIs. Salvage was more likely to be attempted when patients were under the direct care of an intestinal rehabilitation service (95% vs. 68%, p = 0.04). The overall successful salvage rate was 91.6% (n = 77). Gram-positive, Gram-negative, and polymicrobial infections had successful salvage rates of 97%, 92%, and 94% respectively. The successful salvage rate for fungal infections was 40%. There was no difference in 30-day complication rates for hospital readmission, intensive care unit admission, and death between patients who underwent salvage attempt and those who did not. CONCLUSIONS: Central line salvage can be safely attempted for many infections in patients with intestinal failure, leading to vascular access preservation.

Trends in the prevalence and risk factors for peripherally inserted central catheter-related complications in cancer patients from 2016 to 2022: a multicenter study.

PURPOSE: To identify the trends in the prevalence of peripherally inserted central catheter (PICC) related complications in cancer patients and explore the risk factors for complications and occurrence speed. METHODS: A total of 3573 cancer patients with PICC were recruited at 17 hospitals from 2016 to 2022. Logistic and COX regression were performed to identify influencing factors of PICC-related complications and incidence speed, respectively. RESULTS: The proportion of symptomatic PICC-related thrombosis, phlebitis, and infections reported had decreased from 59.1% (in 2017), 11.9% (in 2016), and 11.1% (in 2016) to 15.3% (in 2022), 2.9% (in 2022), and 7.4% (in 2022), and adhesive-related skin injuries and bleeding/oozing reported had increased from 4.8% (in 2016) and 0.0% (in 2016) to 45.5% (in 2022) and 3.4% (in 2022), respectively. Catheter occlusion showed a trend of first increasing and then decreasing from 2.4 (in 2016) to 12.0 (in 2020) to 5.8% (in 2022). Logistic regression showed that hospital level, nature, the patient's gender, age, diagnosis, history of deep vein catheterization, chemotherapy drug administration, and type of PICC were influencing factors of complications. COX regression showed that the patient's gender, age, diagnosis, history of deep vein thrombosis and thrombophlebitis, history of deep vein catheterization, chemotherapy drug administration, type of PICC, type of connector, and StatLock used for fixation were influencing factors of incidence speed. CONCLUSION: The composition ratios of PICC-related complications in cancer patients in China have changed in recent years. Chemotherapy drug administration was a significant risk factor accelerating the occurrence of complications. Maintenance factors had the maximum weight on the COX model, followed by patient factors. It is suggested that patients with high-risk factors be closely monitored and proper maintenance be performed to prevent and delay the occurrence of PICC-related complications.

[Expert consensus on the whole-course management of implantable venous access port in the upper arm of cancer patients (2023 Edition)].

With the widespread application of ultrasound-guided Sedinger puncture techniques and intracardiac electrocardiogram positioning technology, implantable intravenous drug delivery device (IVAP) in the upper arm has been recognized by the majority of medical personnel and cancer patients due to its advantages of hiding scars and completely avoiding the risk of hemothorax and pneumothorax. In order to standardize the clinical application of IVAP via the upper arm approach in cancer patients, improve the success rate of implantation, reduce complications and improve patient satisfaction, the Breast Cancer Expert Committee of the National Cancer Quality Control Center consulted guidelines and the latest evidence-based evidences and established the expert consensus on the whole-course management of implantable venous access port in the upper arm of cancer patients, in order to provide reference for the standard application of IVAP in the upper arm. The consensus mainly introduces the indications, contraindications, preoperative evaluation, implantation site, operation procedure, utilization and maintenance, complications and management, medical staff training and patient education of IVAP in the upper arm, in order to provide reference for clinical staff.
