A multicenter retrospective study on 4480 implanted PICC-ports: A GAVeCeLT project.

PICC-ports may be defined as totally implantable central venous devices inserted in the upper limb using the current state-of-the-art techniques of PICC insertion (ultrasound-guided venipuncture of deep veins of the arm, micro-puncture kits, proper location of the tip preferably by intracavitary ECG), with placement of the reservoir at the middle third of the arm. A previous report on breast cancer patients demonstrated the safety and efficacy of these devices, with a very low failure rate. This retrospective multicenter cohort study-developed by GAVeCeLT (the Italian Group of Long-Term Venous Access Devices)-investigated the outcomes of PICC-ports in a large cohort of unselected patients. The study included 4480 adult patients who underwent PICC-port insertion in five Italian centers, during a period of 60 months. The primary outcome was device failure, defined as any serious adverse event (SAE) requiring removal. The secondary outcome was the incidence of temporary adverse events (TAE) not requiring removal. The median follow-up was 15.5 months. Device failure occurred in 52 cases (1.2%), the main causes being local infection (n = 7; 0.16%) and CRBSI (n = 19; 0.42%). Symptomatic catheter-related thrombosis occurred in 93 cases (2.1%), but removal was required only in one case (0.02%). Early/immediate and late TAE occurred in 904 cases (20.2%) and in 176 cases (3.9%), respectively. PICC-ports are safe venous access devices that should be considered as an alternative option to traditional arm-ports and chest-ports when planning chemotherapy or other long-term intermittent intravenous treatments.

Demonstration of an Analytic Process using Home Health Care Electronic Health Records: A Case Example Exploring the Prevalence of Patients with a Substance Use History and a Venous Access Device

Electronic health records (EHR) are an important, but underutilized source for home health care research and practice improvement. Although the use of EHR is more efficient than prospective data collection, an analysis of EHR data can be complex and time-consuming. To demonstrate the overall process, we describe a secondary analysis of EHR data that explored the prevalence of home health care patients with a substance use history (SUH) and a venous access device (VAD). We detail our process of EHR data extraction, management, and analysis to assist researchers and clinicians interested in similar work. The example analysis showed that that 10.6% of adult home health care patients had a SUH, 8.8% had a long-term VAD, and 1.3% had both. EHRs can be a valuable data source for home health care research and quality improvement projects, but a systematic and thoughtful strategy is needed to fully leverage their potential.

Long-term venous access devices: A lifeline for patients with cancer

Long-term venous access devices: A lifeline for patients with cancer

Ultrasound guidance for Port-A-Cath insertion in children; a comparative study.

BackgroundGaining vascular access in children is challenging. Ultrasound-guided central line insertion in adults became the standard of care; however, its role in children is not clear. Our objective was to evaluate the ultrasound-guided Port-A-Cath or totally implanted long-term venous access device insertion in pediatric patients compared to the traditional approach.MethodsThis single-institution retrospective cohort study included 169 children who had port-A-catheters between May 2016 and Oct 2019. The patients were divided into two groups; group A included patients who had Port-A-Cath insertion using the landmark method (n = 117), and Group B included patients who had ultrasound-guided Port-A-Cath insertion (n = 52). Preoperative, operative, and postoperative data were collected and compared between the two groups. The study outcomes were operative time and catheter insertion-related complications.ResultsThere was no significant difference in age or gender between both groups (P = .33 and .71, respectively). Eleven cases in group A and two cases in group B were converted to cut down technique because of difficulty in inserting the guidewire. There was no difference in the indication of the need for the port-A-Cath between both groups. The mean operative time for group A was 47 min and for group B was 41.7 min (P < .042). Two patients had intraoperative bleeding and hemothorax and required blood transfusion and chest tube insertion in group A. No statistically significant difference was found in the reported complications between the groups. However, the insertion-related complications were higher in group A (P = .053). No procedure-related mortality was reported.ConclusionsUltrasound-guided insertion of Port-A-Cath is an effective and safe technique with a reduction of failure rate. It should be considered the standard technique for Port-A-Cath insertion in the pediatric population.

Extravasation (Paravasation) of Chemotherapy Drugs - Recommendations for Standard Care in the Czech Republic based on Consolations between Representatives of the Supportive Care Group of the Czech Society for Oncology, Oncology Section of the Czech Nurses Association, and the Society for Ports and Permanent Catheters.

Extravasation (paravasation) of chemotherapy drugs is a very significant complication in the treatment of cancer patients. Preventive and therapeutic interventions reduce the risk of this complication or the extent of its consequences. A working group of authors from expert groups prepared recommendations for standard care. To prepare a basic summary of recommended interventions for daily practice, based on knowledge from long-term, proven, evidence-based practice or on consensus opinions of representatives of expert groups. Preventive measures are essential and include early consideration of long-term venous access device indications, choice of injection site, venous line control before each chemotherapy drug application, and patient education. Interventions in cases of extravasation mainly involve the application of antidotes (dimethylsulfoxide, hyaluronidase, and dexrazoxane) and the application of dry cold or heat, depending on the type of cytostatic drug. Corticosteroids injected subcutaneously, moist heat or cooling, and compression, are not recommended. The recommended procedures will contribute to reducing the risk and consequences of extravasation. The range of recommended interventions can be expanded depending on individual clinical workplace policy and needs. The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manuscript met the ICMJE recommendation for biomedical papers. Submitted: 28. 9. 2019 Accepted: 13. 10. 2019.

A novel ultrasound-guided approach to the axillary vein: Oblique-axis view combined with in-plane puncture.

Ultrasound-guided cannulation of the axillary vein in the infraclavicular area has several potential advantages for both short-term and long-term venous access devices. Currently, there are two techniques to approach axillary vein for ultrasound-guided cannulation: out-of-plane puncture in the short-axis view and the in-plane puncture in the long-axis view. We propose a novel ultrasound-guided puncture technique of axillary vein for centrally inserted central catheter placement, which consists in the oblique-axis view of the axillary vein coupled with the in-plane puncture. The main objectives of this study were feasibility and safety of this approach. The primary endpoints were the success rate and early complications; the secondary endpoints were late complications. We analyzed data from a retrospective cohort of 80 ultrasound-guided cannulation of axillary vein performed with the oblique axis-in-plane technique in 80 cancer patients requiring a totally implantable central venous access, at CRO Aviano National Cancer Institute, during the period from January 2016 up to October 2017. We focused on the percentage of successful venous cannulation at the first attempt and on the cumulative incidence of early and late complications. Axillary vein cannulation was successful at the first attempt in 77 out of 80 patients (96%). We had no significant complications during placement or in the first 48 h. The total number of catheter days was 27,432. The cumulative incidence of catheter-related bloodstream infection was of 0.036 per 1000 catheter days (only one case). We had no infection of the pocket of the reservoir, no symptomatic venous thrombosis, and no catheter migration. Our data show that the oblique axis-in-plane technique of the ultrasound approach to the axillary vein is feasible and safe.

Totally Implantable Venous Access Devices: A Review of Complications and Management Strategies.

Totally implantable venous access devices (portacaths, or "ports"), are widely used for intermittent central venous access especially for cancer patients. Although ports have a superior safety margin compared with other long-term venous access devices, there are a number of complications associated with their use. This is a narrative review. We searched PubMed and Google Scholar for articles about complications related to the use of portacaths. "Similar articles" feature of PubMed and reference list of the existing literature were also reviewed for additional relevant studies. In this review, we provide the latest evidence regarding the most common ones of these adverse events and how to diagnose and treat them. Immediate complications including pneumothorax, hemothorax, arterial puncture, and air embolism as well as late complications such as port infection, malfunction, and thrombosis are covered in detail. Physicians should be familiar with port complications and their diagnosis and management.

Abstract No. 450: Outpatient placement of subcutaneous venous access ports reduces the rate of infection and dehiscence compared to inpatient placement

Subcutaneous venous access ports have been shown to reduce the rate of complications compared to other long-term venous access devices, as well as providing a more satisfactory cosmetic appearance and decreased limitation in activities. Although ports have found widespread use in both inpatient and outpatient settings, data comparing infection rates of ports in these two dichotomous patient populations are lacking. The purpose of this study was to determine whether the inpatient-outpatient status of patients at the time of port placement affected the infection rate.

ESPEN Guidelines on Parenteral Nutrition: Central Venous Catheters (access, care, diagnosis and therapy of complications)

When planning parenteral nutrition (PN), the proper choice, insertion, and nursing of the venous access are of paramount importance. In hospitalized patients, PN can be delivered through short-term, non-tunneled central venous catheters, through peripherally inserted central catheters (PICC), or - for limited period of time and with limitation in the osmolarity and composition of the solution - through peripheral venous access devices (short cannulas and midline catheters). Home PN usually requires PICCs or - if planned for an extended or unlimited time - long-term venous access devices (tunneled catheters and totally implantable ports). The most appropriate site for central venous access will take into account many factors, including the patient's conditions and the relative risk of infective and non-infective complications associated with each site. Ultrasound-guided venepuncture is strongly recommended for access to all central veins. For parenteral nutrition, the ideal position of the catheter tip is between the lower third of the superior cava vein and the upper third of the right atrium; this should preferably be checked during the procedure. Catheter-related bloodstream infection is an important and still too common complication of parenteral nutrition. The risk of infection can be reduced by adopting cost-effective, evidence-based interventions such as proper education and specific training of the staff, an adequate hand washing policy, proper choices of the type of device and the site of insertion, use of maximal barrier protection during insertion, use of chlorhexidine as antiseptic prior to insertion and for disinfecting the exit site thereafter, appropriate policies for the dressing of the exit site, routine changes of administration sets, and removal of central lines as soon as they are no longer necessary. Most non-infective complications of central venous access devices can also be prevented by appropriate, standardized protocols for line insertion and maintenance. These too depend on appropriate choice of device, skilled implantation and correct positioning of the catheter, adequate stabilization of the device (preferably avoiding stitches), and the use of infusion pumps, as well as adequate policies for flushing and locking lines which are not in use.

Epidemiology of bloodstream infection associated with parenteral nutrition

Catheter-related bloodstream infections (CR-BSIs) occur in 1.3% to 26.2% of patients with central venous catheters used to administer parenteral nutrition (PN). Because of their nutritional components, PN solutions can support microbial growth. Contamination during preparation and handling is rare in hospitals and home-infusion pharmacies but may be difficult to control in a home setting. The risk of infection is increased in hospitalized patients because of malnutrition-associated immunosuppression, hyperglycemia exacerbated by dextrose infusion, microbial colonization/contamination of catheter hubs and the skin surrounding insertion site, and poor nursing care. During long-term catheter use for PN, an intraluminal biofilm, catheter-tip fibrin sheath or tail, or central venous thrombosis creates sites for microbial seeding and infection. Chronic conditions and psychosocial issues also increase the risk of infection. In hospitalized patients with BSIs, the most common organisms are coagulase-negative staphylococcus, Staphylococcus aureus, Enterococcus, Candida spp, Klebsiella pneumoniae, and Pseudomonas aeruginosa. In the long-term PN population, approximately 60% of CR-BSIs are caused by coagulase-negative Staphylococcus. The best plan of care for a suspected or known infected catheter in a hospitalized patient is to reinsert a new central line after 48 hours of antibiotic treatment and negative blood cultures. In patients who receive long-term PN, hospitalization increases the risk of a nosocomial infection because the catheter can be contaminated by staff. A patient with fungemia must always be admitted and catheter removed. With gram-positive and gram-negative organisms, the catheter may not need to be removed. In most patients receiving PN at home, removing a long-term venous-access device is challenging. Peripheral vein access or peripherally inserted central catheters are needed until a new permanent device can be inserted after negative blood cultures are obtained. Evaluation of remote site infection also is necessary. Strategies to reduce or prevent infection include catheter lock therapy, daily evaluation of continued need for PN, enteral rather than PN support, and avoiding overfeeding. More studies are needed to demonstrate conclusively the benefits of immunonutrition, such as the use of omega-3 or glutamine supplements to reduce CR-BSIs in patients receiving PN.

Interventional radiology in the provision and maintenance of long‐term central venous access

Establishing and maintaining venous access forms an increasing proportion of the workload in interventional radiology. Several patient groups require medium-term to long-term venous catheters for a variety of purposes, including chemotherapy, long-term antimicrobials, parenteral nutrition, short-term access for haemodialysis or exhausted haemodialysis. Often, these catheters are required for treatment and frequent blood testing, which can quickly exhaust the peripheral veins. Long-term venous access devices minimize the discomfort of frequent cannulation while preserving the peripheral veins. Venous access devices include implantable catheters (ports), tunnelled catheters and peripherally inserted central catheters, which have different functions, advantages and limitations. Imaging-guided placement is the preferred method of insertion in many institutions because of higher success rates and radiologists are well suited to address catheter complications.

Tip Position of Long‐Term Central Venous Access Devices Used for Parenteral Nutrition

Venous thrombosis is a potential postplacement complication of a central venous access device (VAD). Improper catheter tip position is a predisposing factor, especially when the device is used to administer parenteral nutrition (PN). American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) guidelines recommend that a central VAD used for PN be placed with its tip in the superior vena cava (SVC) adjacent to the right atrium (RA). The purpose of this study is to determine the prevalence of improper central VAD tip position and factors associated with malpositioning. All adult patients with a longterm VAD (ie, tunneled central venous catheter, peripherally inserted central catheter [PICC], or implanted port) placed before the current admission who were scheduled to receive PN also received chest x-rays to evaluate position of the catheter tip. Position was determined by a staff radiologist. A catheter with its tip ranging from the middle third of the SVC to the RA was considered acceptable; a catheter with its tip in any other position was considered malpositioned. Subjects with multiple VADs or multiple evaluations for the same catheter had the first placement and last evaluation considered. A logistic regression analysis was used to study the univariable and multivariable associations of these factors with tip malposition. Data were collected for catheters in 124 patients, including 74 tunneled catheters (71 Hickman, 2 Broviac, 1 Groshong), 38 PICCs, and implanted ports. Most of the catheters were placed for (81.9%) or chemotherapy (14.5%). Median catheter duration was 1.6 months at time of evaluation. Of 138 catheters studied, 15.9% (95% confidence interval, 10.2-23.1) were malpositioned at time of evaluation. According to univariable analysis, factors associated with malpositioned catheters included shorter catheter duration (p = .001), greater number of lumens (p = .029), venous entry site on the arm (p <.001) and catheters placed at institutions other than Cleveland Clinic (p = .007). Additionally, PICCs were likely to be malpositioned at time of evaluation compared with other long-term VADs combined (34.2% vs 9.0%; p < .001). A high percentage of long-term VADs improperly positioned for PN in the present study. were more likely to be malpositioned at time of evaluation compared with tunneled catheters and implanted These findings suggest the tip position of long-term should be confirmed before infusing PN.

Infection assessment of totally implanted long-term venous access devices

Comparison of catheter tip versus port content culture techniques to assess infection in totally implanted vascular access devices (TIVAD). Comparison of pocket swab, catheter-tip and port content cultures after removing the silicon puncture septum in a prospectively collected consecutive series of 102 TIVAD removed for clinical suspicion of infection, between May 2000 and March 2003. 102 totally implanted port-catheters in 98 patients, age ranging from 1 to 90 years (median 53 years), were removed 7 to 2616 days after insertion (median 210 days). Infection of the pocket surrounding the port was found in 21 cases, all proven by a positive culture of the pocket swab. Out of the remaining 81 cases without pocket infection, 32 had only a positive catheter tip culture, whereas 56 had a positive port content culture (p = 0.0002). Always the same microorganism was isolated in the 32 patients with positive catheter tip and port content cultures. The main organisms identified within TIVAD were Coagulase Negative Staphylococcus (CNS) (41 cases) and Candida sp (15 cases). Eight out of the 21 pocket infections were caused by Staphylococcus aureus. In the presence of local signs of infection, taking cultures of the pocket surrounding the port is sufficient for diagnostic purposes. When infection is localized within the device only, port content cultures taken after removal of the silicon septum are more often positive than cultures of the catheter tip, and constitute therefore a more reliable tool for the assessment of TIVAD infection.

Safer central venous access

Safer central venous access

Safe removal of long-term cuffed Hickman-type catheters.

The use of long-term venous access devices is increasing. Most devices are anchored by a cuff, usually made of Dacron. The disadvantage of such cuffs is that a cut-down procedure is required for their removal. This article presents a simple technique for removal of Hickman-type catheters, emphasizing avoidance of complications.

The Peripherally Inserted Central Catheter: What Are the Current Indications for Its Use?

The use of peripherally inserted central catheters (PICCs) has dramatically increased since first being used for IV therapy in the 1980s. Currently, sales of PICCs are second only to acute care central venous catheters and exceed all other types of long-term venous access devices. The use of PICCs has also increased dramatically in the home care setting. A number of studies have examined the incidence of PICC complications in comparison to other central venous access devices. Although complications differ, most reports have concluded that the type and rate of PICC complications compare favorably with other access devices in the short-term; however, dwell times beyond a few weeks have been associated with decreased complication-free days and lower device survivability rates. The PICC seems to be most appropriate for acute care or short-term home care use and may not be the ideal central venous access device when the need for long-term access is anticipated.
