Abstract
The aim of the overview was to synthesize existing systematic reviews (SRs) of flushing interval for patients who inserted totally implanted venous catheter devices (TIVAD). Regular flushing is indispensable for catheter patency, the recommended flushing interval of TIVAD is 4 weeks, however, there is an argument for prolonging the maintenance interval, which has been proved by many SRs. However, the flushing interval range from 4-week to 3-month. The discrepancy in maintenance period could puzzle health professionals and hinder best practice into the clinic. So, we performed the overview by following the PRISMA statement. The PubMed, Ovid, Wan Fang database, Web of Science, CINAHL, CNKI, EMBASE, Cochrane Library were searched from inception to November 2021. The AMSTAR-2, the PRISMA statement, and ROBIS tool were used to assess SRs' method, report quality, and risk of bias, respectively. Then all results were synthesized, the quality of SRs' results was evaluated with GRADE. Finally, five SRs were included. However, non-randomized and small sample size of original studies result in the limitation of SRs. The evidence grade of conclusions is low, bias of mixed factors in included studies, further large sample sizes, RCTs need to be conducted in the future. Prolonged flushing interval was feasible based on the recent evidence, especially during the COVID-19 pandemic because the overwhelming healthcare system and inconvenience of transportation made maintenance not as easy as it used to be. There is no difference of complication between prolonged flushing interval (⩾4-week) and 4-week period, and it can also reduce healthcare cost with no harm to patients.

Abstract
BACKGROUND Although the number of patients who need central venous ports for permanent vascular access is increasing, there is still no “gold standard” for the implantation technique.
AIM To identify the implantation technique that should be favored.
METHODS Two hundred central venous port-implanted patients in a tertiary hospital were retrospectively evaluated. Patients were assigned into two groups according to the access method. The first group comprised patients whose jugular veins were used, and the second group comprised patients whose subclavian veins were used. Groups were evaluated regarding age, sex, application side, primary diagnosis, active follow-up period in the hospital, chemotherapy agents administered, number of complications, and the Clavien-Dindo severity score. The distribution of the variables was tested with the Kolmogorov-Smirnov test and the Mann-Whitney U test. The χ2 test was used to analyze the variables.
RESULTS There was no statistically significant difference between the groups regarding age, sex, side, number of chemotherapy drugs, and duration of port usage (P > 0.05). Only 2 patients in group 1 had complications, whereas in group 2 we observed 19 patients with complications (P < 0.05). No port occlusion was found in group 1, but the catheters of 4 patients were occluded in group 2. One port was infected in group 1 compared to three infected ports in group 2. Two port ruptures, two pneumothorax, one revision due to a mechanical problem, one tachyarrhythmia during implantation, and four suture line problems were also recorded in group 2 patients. We also showed that it would be sufficient to evaluate and wash ports once every 2 mo.
CONCLUSION Our results robustly confirm that the jugular vein route is safer than the subclavian vein approach for central venous port implantation.

Abstract
AimTo investigate the safety and feasibility of extending the flushing interval for the totally implantable venous access port (TIVAP) during the non-treatment stage in patients with breast cancer (BC) by retrospectively analyzing the patients’ clinical data, including the incidence of TIVAP-related complications.MethodsThis single-center retrospective study included patients with BC who underwent TIVAP implantation at our hospital between January 2018 and March 2021 during their non-treatment phase and visited the hospital regularly for TIVAP flushing. Among the 1013 patients with BC who received TIVAP implantation, 617 patients were finally included on the basis of the inclusion and exclusion criteria and divided into three groups according to the length of the flushing interval: group 1 (≤30 days, n = 79), group 2 (31–90 days, n = 66), and group 3 (91–120 days, n = 472). The basic characteristics of patients in each group and the incidence of TIVAP-related complications (catheter obstruction, infection, and thrombosis) were analyzed.ResultsNo significant intergroup differences were observed in age, body mass index (BMI), tumor stage, pathological staging, implantation approach, chemotherapy regimen, duration of treatment, and TIVAP-related blood return rate (P > 0.05). Among patients from all three groups, 11 cases of catheter pump-back without blood and eight cases of TIVAP-related complications such as infection, thrombosis, and catheter obstruction were recorded. However, no significant differences in TIVAP-related complications were observed among the three groups (P > 0.05).ConclusionExtending the TIVAP flushing interval beyond three months during the non-treatment stage in BC patients is safe and feasible and did not increase the incidence of TIVAP-related complications.

Abstract
Objective To assess the safety and efficacy of port-locking with heparin every 2 months vs. every 4 months and vs. saline solution every 2 months in patients with cancer not receiving active chemotherapy. The hypothesis stated that locking with heparin at four-month intervals and saline at two-month intervals would not increment > 10% of port obstructions. Methods Multicentre, phase IV parallel, post-test control group study took place at the two chemotherapy units of oncology hospitals. Included patients with cancer with ports that completed the chemotherapy treatment but still having port maintenance care or blood samples taken up to four months. A sample of 126 patients with cancer in three arms was needed to detect a maximum difference of 10% for bioequivalence on the locking methods. Consecutive cases non-probabilistic sampling and randomized to one of the three groups; group A: received heparin 60 IU/mL every two months (control) vs. group B heparin every four months and vs. saline every two months in group C. Primary variables were the type of locking regimen, port obstruction, and absence of blood return, port-related infection, or venous thrombosis during the study period. Clinical and sociodemographic variables were also collected. Results A total of 143 patients were randomly assigned; group A, 47 patients with heparin every 2 months, group B, 51 patients with heparin 4 months, and group C, 45 patients with saline every 2 months. All participants presented an adequate blood return and no obstructions, until the month of the 10th, when one participant in the group A receiving was withdrawn due to an absence of blood flow (P = 0.587). Conclusions Port locks with heparin every 4 months or saline every 2 months did not show differences in safety maintenance, infection, or thrombosis compared to heparin every 2 months.

Abstract
BACKGROUND Recently, some studies have shown that prolonging flush interval is safe and feasible for patients who complete chemotherapy. However, there is no consensus about the optimal flush interval for those patients. OBJECTIVE The purpose of this review was to evaluate whether the flush interval could be prolonged based on monthly interval for regular maintenance and to explore the optimal flush interval. DATA SOURCES We searched the following databases for articles published between 1 January 1982 and 21 February 2020: PubMed, Cochrane Library, Web of Science, EMBASE, CINAHL, and Ovid. STUDY ELIGIBILITY CRITERIA Randomized controlled trials, retrospective and prospective cohort studies of flush interval less than 4 weeks versus longer than 4 weeks for patients who completed chemotherapy, were included. RESULTS Two reviewers extracted information and assessed the quality of the articles independently. In total, 389 articles were retrieved, and 4 studies including 862 cases fulfilled the inclusion criteria. There was no statistical heterogeneity (I2 = 0, p > 0.05) among the included studies. Hence, the fixed-effects model was used for the meta-analysis. The meta-analysis showed that the total complication rate associated with longer than 4-week interval was higher than that associated with less than 4-week interval. Nevertheless, there was no significant difference between the two groups (7.2% vs 7.6%, p = 0.83). Moreover, the meta-analysis showed that the total complication and catheter occlusion rates associated with the 4-week interval were higher than those associated with the 8-week interval. However, there was no significant difference between the two groups (total complications: 11.4% vs 9.5%, p = 0.68; catheter occlusions: 4.9% vs 4.1%, p = 0.89). LIMITATIONS Only four non-randomized controlled studies were included, and the outcomes of the included studies were reported incompletely. CONCLUSION Extending the flush interval to longer than 4 weeks is safe and feasible. Based on previous studies, extending the flush interval to 8 weeks might not increase the incidence of total complications and catheter occlusions. However, there is no conclusion on whether the flush interval could be extended to 3 months or longer.

Abstract
Regular flushing and locking of totally implantable venous access devices (TIVADs) is recommended to maintain their patency when not in use. In this case report, a 73-year-old male patient received radical resection for rectal carcinoma in January 2010. A TIVAD was implanted in 2014 and a total of 12 rounds of chemotherapy of FOLFIRI was completed in 2015. During the period from 2015 to 2020, the patient never used or conducted the monthly infusion port flushing because of the inconvenience, the COVID-19 pandemic, and so on. On 18th April 2020, the patient was admitted to the radiotherapy department of Yiwu Central Hospital. The nurse evaluated the TIVAD upon admission, finding that the skin around the reservoir was normal without any sign of infection as erythema or induration of the skin overlying the implantable port but there was intraluminal occlusion of the devices. In order to re-access the catheter, discussion of a MDT was performed and several days of unremitting efforts were tried. Gratifyingly, the patient's port was re-accessed successfully without any adverse reactions. This is a rare infusion port that has not been used and maintained for 5 years. For the port that has not been used and maintained for a long time up to 5 years, the medical staff should not give up easily. During the COVID-19 pandemic, prolonging the flushing interval of TIVADs can be an optimal clinical strategy without negative outcomes.

Abstract
BACKGROUND Flushing and locking of totally implantable venous access devices (TIVADs) is recommended to maintain their patency when not in use. Although manufacturers' recommendations indicate monthly access for TIVAD maintenance, there is a tendency in real life to prolong this interval. OBJECTIVES To assess the effectiveness of prolonged versus short flushing and locking intervals to prevent TIVAD occlusions in adults with cancer. METHODS A systematic search was carried out in MEDLINE, EMBASE, CINAHL, and Web of Science. Two reviewers independently selected studies, assessed quality, and extracted data. Study findings were summarized, and a meta-analysis conducted. RESULTS Six articles were included in the review, with a total of 1255 participants. Differences in types of cancers, flushing and locking techniques, and volume and concentration of heparin were described. Pooled results from 4 studies showed fewer catheter occlusions in favor of prolonged flushing and locking intervals (relative risk, 0.81), even if not statistically significant (95% confidence interval, 0.41-1.61) with no heterogeneity among studies (I2 = 0.00%, P = .69). The quality of evidence was very low. CONCLUSIONS Very low-quality evidence suggests that prolonged schedule flushing and locking intervals has no effect on catheter patency. However, because of low number and poor quality of evidence derived from the studies analyzed, findings of this meta-analysis should be interpreted with caution. IMPLICATIONS FOR PRACTICE No statistically significant difference in occlusion rate between short and long timing of flushing was found. However, further studies are necessary to strengthen the safe implementation of longer intervals in clinical practice.

Abstract
Objectives To assess whether the extension of the flushing interval will increase risks of complications associated with totally implantable venous access port (TIVAP) in the off-treatment period. Methods A retrospective single-center observational study was performed. Patients with a TIVAP in the off-treatment period that underwent regular flushing in our clinic were included. Data concerning patients and their TIVAPs were recorded. Patient baseline characteristics and TIVAP-related complications were analyzed. Continuous variables were analyzed by ANOVA or the Kruskal-Wallis H test. To compare the occurrence of TIVAP-related complications, the chi-square test was used; if needed, Fisher’s exact test was used. Results Totally 607 patients were reviewed, and 563 patients were finally included. Thirteen complications were recorded, including 11 cases of catheter occlusion (1.95%), one case of port cannula rotation (0.18%), and one case of catheter tip malposition (0.18%). No device-related infection or venous thrombosis was recorded. Among these patients, the average flushing interval was 35.27 ± 13.09 days. Patients were divided into three groups according to the flushing interval: every 28 days or less (Group 1, n = 133); every 29–44 days (Group 2, n = 350); and every 45 days or more (Group 3, n = 80). No significant difference in catheter-related complications was found among the three groups (P > 0.05). Conclusions In the TIVAP off-treatment period, patients without any history of TIVAP-related complications during approximately one year can attempt to prolong the flushing interval to more than 4 weeks; we further suggest that 5–6 weeks may be an appropriate option for these patients.

Abstract
AIM The use of heparin and 0.9% saline solution is always controversial for central venous catheters. However, there is no systematic review or guideline about whether saline solution can replace heparin solution in adult cancer patients with totally implantable venous access ports (TIVAPs). The purpose of this review is to evaluate whether saline solution can replace heparin saline to lock TIVAPs. METHODS The following databases were searched: PubMed, the Cochrane Library, Web of Science, Embase, CINAHL and Ovid (January 1, 1982, and February 21, 2020). All statistical analyses of the meta-analysis were completed using the Review Manager 5.3. RESULTS A total of 201 studies were identified from these databases after initial review, and four studies met inclusion criteria, including 2652 cases. There was little heterogeneity among the included studies (I2 < 30%), and all analyses were conducted by the fixed-effects model. The total complications, catheter occlusions, catheter-related bloodstream infections and other complication rates in the heparin solution group were higher than in the saline solution group. In the subgroup analysis of heparin concentration, total complication rates in the saline solution group were higher than with 50 U of heparin and lower than with 100 U of heparin. However, the differences in these complications were small, and no significant difference was observed (all P > 0.05). CONCLUSIONS Based on existing clinical studies, we recommend that saline solution can replace 50 or 100 U/ml of heparin as a safe and effective flush solution for TIVAPs.

Abstract
The objective of this systematic review is to evaluate the safety ad feasibility of the totally implantable vascular access devices (TIVADs) flushed more than 4 weeks. We searched the following electronic databases from the date their build-up to February 2020: PubMed, EMBASE, The Cochrane Central Register of Controlled Trials (CENTRAL), and CINAHL. The final selection resulted in 14 trials fulfilling the inclusion criteria and being included in our review. A pooled frequency of port-related late complications with longer flushing intervals (>4 weeks) was 8.0%, and the pooled frequency of occlusions, infections, and mechanical complications was 5.0%, 2.0%, and 3.0%, respectively. Then, we compared the frequency of port-related complications between standard and longer flushing intervals. There were no differences between the group's changes in the frequency of total late complications, occlusions, infections, and mechanical complications. This systematic review and meta-analysis demonstrates that longer flushing intervals for ports are safe. However, more prospective, power appropriated randomized trials are needed to explore the specific flushing time for ports.

Abstract
Patients with colorectal cancer (CRC) treated with curative intent surgery undergo continuous fluorouracil (5-FU) infusion-based chemotherapy using totally implantable central venous port system (TICVPS) in cases with high risk of recurrence. Approximately 30% of patients relapse after therapy completion, especially within 2 years. Hence, many patients with high risk CRC keep the TICVPS for 6 to 24 months after treatment with regular intervals of TICVPS flushing. However, little is known about the proper interval duration of the port. The aim of this study is to investigate whether a 3 months extended interval is safe and if port maintenance is feasible.A retrospective cohort was compiled of patients with CRC who underwent curative intent surgery and perioperative chemotherapy using TICVPS between 2010 and 2017. The primary end point was TICVPS maintenance rate, including maintenance of TICVPS for at least 6 months, planned TICVPS removal after 6 months, and regaining the use of TICVPS at the time of recurrence.A total of 214 patients with CRC underwent curative intent treatments during the study period. Among them, 60 patients were excluded, including 6 patients for early recurrence within 3 months and 54 patients with violation of flushing interval. Finally, 154 patients were analyzed. Mean flushing interval was 98.4 days (95% confidence interval [CI], 96.2-100.6; range, 60-120). In December 2018, 35 patients kept the TICVPS, 92 patients had planned removal, 25 patients reused the TICVPS, and 2 patients had to unexpectedly remove the TICVPS due to site infection and pain. Thus, the functional TICVPS maintenance rate was 98.8% (152/154). Thirty-eight patients relapsed, and 30 patients were treated with intravenous chemotherapy. Among them, 25 patients (83.3%) reused the maintained TICVPS without a reinsertion procedures.Our study demonstrated that 3-month interval access and flushing is safe and feasible for maintaining TICVPS during surveillance of patients with CRC. An extended interval up to 3 months can be considered because it is compatible with CRC surveillance visit schedules.

Abstract
Several recent literature reports regarding the flushing technique of TIVADs highlight how the definition of the optimal flushing interval is still a source of controversy. Several recent studies indicate more and more frequently how 4 weeks can be considered a too short interval for the flushing of a totally implantable access device (TIVAD); on the other hand most of the main guidelines and instructions for use provided by the device’s manufacturers still suggest an interval between 4 weeks and 1 month as the ideal one. The recent meta-analysis by Wu et al. on this topic, promotes an important strategy change, indicating the possibility of extending the flushing intervals at least up to 8 weeks. This editorial extensively discusses the flushing methods of TIVADs highlighting the need for important and substantial changes, both in extending the range of flushes and in the solutions and methods to be used. It represents an invitation to the scientific community and device manufacturers for a complete revision of the indications on flushing techniques.

Abstract
Nursing staff play a crucial role in maintaining a functional port. Nursing guidelines recommend standard maintenance with 10 ml irrigation without consideration for variations among patients and individual nursing staff. The aim of this study is to identify the efficacy of the current maintenance strategy and analyze the correlation between complications and actual port presentations, based on disassembled intravenous ports after removal from patients. We attempt to organize the information and propose a definite maintenance strategy.After treatment completion, or due to complications, 434 implanted intravenous ports were removed from patients. All ports were deconstructed to observe their actual presentations and were then analyzed in conjunction with medical records. The correlation between complications and actual presentations was analyzed.From March 2012 to December 2017, 434 implanted intravenous ports were removed from oncology patients after completion of treatment or catheter related complications. From the view of maintenance related presentations, injection chamber blood clot was highly correlated with chemotherapy completion (P < .001) and malfunction (P = .005), while tip blood clot (P = .043) was related with chemotherapy completion and catheter fibrin (P = .015) was related to malfunction. From the view of structure related presentations, broken catheter integrity was correlated to chemotherapy completion (P = .007), fracture (P < .001), and malfunction (P = .008). Compression groove was related to chemotherapy completion (P = .03) and broken catheter at protruding stud was related to fracture (P = .04), while diaphragm rupture was correlated to chemotherapy completion (P = .048) and malfunction. (P < .001).Current port maintenance is insufficient for ideal port maintenance, whereby maintenance-related presentations, including tip clot, catheter fibrin, and injection chamber blood clot were identified. We propose a recommended maintenance strategy based on our findings. Structure-related presentations, including broken catheter integrity, broken catheter at protruding stud and diaphragm rupture were seen in patients with longer implantation period. Removal of the implanted port may be considered after 5 years if no disease relapse is noted.

Abstract
Totally implantable venous access device (TIVAD) lumen occlusion is a long-term complication of central venous catheters, associated with risks of infection, therapy interruptions and increased healthcare costs. The role of flushing and locking in maintaining TIVAD patency is paramount. Most flushing protocols are based on manufacturers' recommendations, which indicate that 4 weeks is the safest interval between two consecutive flushing procedures during periods when TIVADs are not in use. Conversely, results of several studies suggest that extended flushing intervals (FIs) do not increase the rate of obstructive or infective complications. The study aimed to describe the effects of prolonged FIs in a cohort of 317 patients with cancer. The authors found no significant difference in terms of TIVAD problems between long (>45 days) and short (≤45 days) FI groups, which raises questions over the validity of current practice.

Abstract
Background Two prevailing, totally implantable venous access ports are routinely utilized in oncology: chest port or arm port. This systematic review with meta-analysis was conducted to compare safety and efficiency of the two techniques. Methods We performed evidence acquisition intensively from PubMed, Embase, and Cochrane Library. Available comparative studies that evaluated both techniques were identified. The outcomes of interest included total complication events, procedure-related infections, thrombosis, intra-operative complications, mechanical complications, conversion rate, early port removal, and operating time. Results Thirteen comparative studies including 3,896 patients (2,176 for chest ports, and 1,720 for arm ports) were identified. The present study showed that arm port was associated with higher procedure conversion rate (2.51% in chest port group and 8.32% in arm port group; odd ratios [OR] 0.27, 95% confidence interval [CI] 0.15-0.46; p<0.001), but lower incidence of intra-operative complications (1.38% in chest port group and 0.41% in arm port group; OR 2.38, 95% CI 1.07-5.29; p=0.03). There were no between-group differences with respect to total complication events, procedure-related infections, thrombosis, mechanical complications, early port removal, and operating time. Subgroup analysis of patients under 60 years revealed that no significant difference was detected in intra-operative events (1.19% in chest port group and 0.02% in arm port group, OR 2.59, 95% CI 0.74-9.08; p<0.14), indicating that age may be a risk factor for intra-operative events. Sensitivity analysis did not change conclusions of all endpoints of interest. Conclusion Arm port is associated with higher procedure conversion rate, but lower incidence of intra-operative complications, and age may be a risk factor for intra-operative events.

Abstract
AIM The aim of this study was to compare peripheral arm ports versus central chest ports in complication rates. BACKGROUND Late complications of arm ports versus chest ports, including catheter-related infection, venous thrombosis and catheter obstruction, remain controversial. DESIGN A meta-analysis conducted following the Cochrane handbook. DATA SOURCES Studies published between 1950-August 2017 were searched through Pubmed, Embase, Web of science and Cochrane library. REVIEW METHODS Two authors independently searched the eligible studies and extracted the data. Studies reporting complications of arm ports compared with chest ports, published in full texts and abstracts, were included. The quality of the studies was assessed with the Newcastle-Ottawa Scale. We did subgroup analyses according to cancer type, age, follow-up and anticoagulant. Relative ratios were calculated with different models. RESULTS A total of 15 articles covering 3,524 tumour patients met the eligibility criteria. There was no difference in catheter-related infection and catheter obstruction between arm ports and chest ports. After reducing the high heterogeneity, no difference was observed in thrombosis overall; however, arm ports had a lower thrombosis rate than chest ports in patients with head and neck cancer, while a higher thrombosis rate was observed in patients <60 years old or follow up ≥1 year. Further studies are needed in venous thrombosis. CONCLUSIONS Arm ports are a safe option beside chest ports for adult patients with malignancy, especially in patients with head-neck cancer or breast cancer. Patients should be well informed of the advantages and disadvantages of different vascular access devices and provided a choice.

Abstract
BACKGROUND Normal saline is considered a safe alternative for heparin as a locking solution in totally implantable venous access devices. The incidence rate of partial occlusion with the use of normal saline (easy injection, impossible aspiration) is estimated at 4%. OBJECTIVE The aim of this study was to investigate determinants of partial occlusions with the use of normal saline solution and the maintenance of positive pressure in the catheter. METHODS We enrolled 218 patients with different solid tumors who underwent pharmacologic treatment through the port with different frequencies: from once every week to at least once every month. The port was flushed with normal saline solution keeping a positive pressure in the catheter. RESULTS We performed 4111 observations and documented normal port functioning in 99% of observations (n = 4057) and partial occlusions in 1% of observations (n = 54). Partial occlusions were significantly associated with frequency of port flushing (P < .05), chemotherapy (P < .001), and blood sample collection (P < .001). CONCLUSIONS The use of positive pressure in addition to normal saline reduces the incidence rate of partial occlusions. The type of treatment, blood sample collection, and treatment schedule are important determinants of partial occlusions. IMPLICATIONS FOR PRACTICE Nurses play a key role in maintaining a functioning port using positive pressure during the flushing techniques. Certain risk factors must be monitored to prevent partial occlusions, and certain patients are more likely to present with port-related problems.

Abstract
INTRODUCTION Patients with cancer need stable venous access using central vascular devices like central venous ports and peripherally inserted central catheters that can be used for a wide range of indications. Numerous flushing protocols exist including different frequencies for catheter locking to maintain catheter patency. The aim of this retrospective study was to evaluate the incidence of lumen occlusion of central venous ports in a group of adult cancer patients, adopting a policy of locking with normal saline every three months. METHODS This is a single-center retrospective observational study. During follow-up, we analyzed adult cancer patients who had undergone port insertion from January 1st, 2007 to August 31st, 2014. Flushing and locking were performed every three months with a syringe containing normal saline. RESULTS We collected data from 381 patients with ports inserted in subclavian vein (379 patients) and in the right jugular vein (2 patients). Locking was performed during 3-monthly follow-up visits. Median follow-up was 810 days (90-2700 days). Among 381 ports, 59 were removed; the reasons for removal were: end of use (45 cases), catheter rupture (9 cases), dislocation (3 cases) and catheter-related bloodstream infection (2 cases). We had no reports of lumen occlusion. CONCLUSIONS Our data suggest that locking ports with normal saline every three months is not associated with an increased risk of lumen occlusion.

Abstract
PURPOSE Retrospective studies suggest that it may be safe to extend the maintenance flushing interval of implanted ports from once every month, as recommended by the manufacturer, to once every 3 months, but no prospective cohort studies have been done specifically assessing the safety and feasibility of this intervention. METHODS This was a phase II study in oncologic patients who retained a functional port after completion of systemic chemotherapy. Patients enrolled in the study had their port flushed once every 3 months and were observed until completion of five scheduled flushes (one on enrollment and four additional flushes, one every 3 months) or development of any port-related complication, including infections, thrombosis, and occlusions. The primary end points were frequency of port-related complications and port failure requiring removal. RESULTS A total of 87 patients were enrolled in the study. The median follow-up time was 308 days, accounting for a total of 24,202 catheter-days. There were 10 port-related complications (11.49%; 95% CI, 4.85% to 18.14%). No infection or symptomatic thrombosis occurred. The mean time to port-related complication was 184 days. No patients developed port failure while on protocol, but on subsequent medical record review, four patients developed a complication that required port removal or port revision within 30 days of being removed from the trial (4.6%; 95% CI, 0.4% to 8.8%; 0.17/1,000 catheter-days). CONCLUSION Extending the maintenance flushes of implanted ports in adult oncologic patients to once every 3 months is safe, effective, and likely to increase patient adherence and satisfaction while decreasing the associated cost.

Abstract
Background A totally implantable venous access device (TIVAD) provides reliable, long-term vascular access and improves patients’ quality of life. The wide use of TIVADs is associated with important complications. A meta-analysis was undertaken to compare the internal jugular vein (IJV) with the subclavian vein (SCV) as the percutaneous access site for TIVAD to determine whether IJV has any advantages. Methods All randomized controlled trials (RCTs) and cohort studies assessing the two access sites, IJV and SCV, were retrieved from PubMed, Web of Science, Embase, and OVID EMB Reviews from their inception to December 2015. Random-effects models were used in all analyses. The endpoints evaluated included TIVAD-related infections, catheter-related thrombotic complications, and major mechanical complications. Results Twelve studies including 3905 patients published between 2008 and 2015, were included. Our meta-analysis showed that incidences of TIVAD-related infections (odds ratio [OR] 0.71, 95 % confidence interval [CI] 0.48–1.04, P = 0.081) and catheter-related thrombotic complications (OR 0.76, 95 % CI 0.38–1.51, P = 0.433) were not significantly different between the two groups. However, compared with SCV, IJV was associated with reduced risks of total major mechanical complications (OR 0.38, 95 % CI 0.24–0.61, P < 0.001). More specifically, catheter dislocation (OR 0.43, 95 % CI 0.22–0.84, P = 0.013) and malfunction (OR 0.42, 95 % CI 0.28–0.62, P < 0.001) were more prevalent in the SCV than in the IJV group; however, the risk of catheter fracture (OR 0.47, 95 % CI 0.21–1.05, P = 0.065) were not significantly different between the two groups. Sensitivity analyses using fixed-effects models showed a decreased risk of catheter fracture in the IJV group. Conclusion The IJV seems to be a safer alternative to the SCV with lower risks of total major mechanical complications, catheter dislocation, and malfunction. However, a large-scale and well-designed RCT comparing the complications of each access site is warranted before the IJV site can be unequivocally recommended as a first choice for percutaneous implantation of a TIVAD.

Abstract
Flushing and locking of intravenous catheters are thought to be essential in the prevention of occlusion. The clinical sign of an occlusion is catheter malfunction and flushing is strongly recommended to ensure a well-functioning catheter. Therefore fluid dynamics, flushing techniques, and sufficient flushing volumes are important matters in adequate flushing in all catheter types. If a catheter is not in use, it is locked. For years, it has been thought that the catheter has to be filled with an anticoagulant to prevent catheter occlusion. Heparin has played a key role in locking venous catheters. However, the high number of risks associated with heparin forces us to look for alternatives. A long time ago, 0.9% sodium chloride was already introduced as locking solution in peripheral cannulas. More recently, a 0.9% sodium chloride lock has also been investigated in other types of catheters. Thrombolytic agents have also been studied as a locking solution because their antithrombotic effect was suggested as superior to heparin. Other catheter lock solutions focus on the anti-infective properties of the locks such as antibiotics and chelating agents. Still, the most effective locking solution will depend on the catheter type and the patient's condition.

Abstract
This article describes a literature review of published evidence on infection prevention and control in central venous access device (CVAD) care conducted by a novice researcher (lead author) under the supervision of her lecturer (second author). It includes details of the search as well as of the analysis which led to the selection and critical appraisal of a selected article identified and, importantly, discussion of the limitations and lessons learned by the novice researcher with her experimental approach. Infection control is paramount within nursing practice as a result of the number of healthcare-associated infections, which are preventable if evidence-based practice is followed and when trust protocols are informed by evidence. The question posed by the author prior to undertaking the literature search related to whether the use of sterile gloves for CVADs reduces infections in the oncology patient population compared with the use of non-sterile gloves. The question was formulated using the PICO (Population, Intervention, Comparison, Outcome) process and relevant literature was located using CINAHL and MEDLINE databases. The results of the review demonstrated no significant difference in infection rates using sterile or non-sterile gloves when handling CVADs but further research in this area is needed to validate the findings.

Abstract
In the light of nurses' questions regarding the handling of the totally-implanted venous access device, this study aimed to evaluate these professionals' knowledge. This is a descriptive study with a qualitative approach, whose sample was made up of 28 nurses working on the Internal Medicine ward and in the Emergency Room. The study was undertaken in two stages: interviewing, to evaluate knowledge regarding the handling of the implanted port; and an integrative review to clarify the doubts identified. The results indicated that the nurses' knowledge was inadequate regarding when to use the implanted port, its purpose, the puncture technique, maintenance and handling. It is concluded that the knowledge of the subjects evaluated is inadequate, and that it is necessary for these professionals' clinical skills to be standardized and for them to receive theoretical-practical training.

Abstract
PURPOSE The aim of this systematic review was to assess the efficacy of heparin flushing in the lock of central venous catheters. METHODS We searched MEDLINE and CINAHL databases. Eligible studies were randomized controlled trials evaluating the use of heparin versus normal saline or other solution in the flushing of central catheter among adult patients. No language restrictions were applied. Two reviewers independently screened titles and abstracts in order to identify relevant publications. The same two reviewers retrieved and evaluated full texts. Parameter estimates regarding catheter occlusion were pooled using network meta-analysis with Bayesian hierarchical modeling. RESULTS We identified 462 references. Eight studies were included. There was no evidence that heparin was more effective than normal saline in reducing occlusions. It was unclear whether urokinase and lepirudin were more effective than heparin in reducing occlusions. Vitamin C solution does not appear to prolong catheter patency. CONCLUSIONS There is no evidence of a different effectiveness between heparin flushing and normal saline or other solutions in reducing catheter occlusions. Due to the little and inconclusive evidence available in this field, further studies might be necessary.

Abstract
PURPOSE To evaluate the effectiveness of irrigating totally implantable venous access devices (TIVADs) every eight weeks instead of every four in maintaining the patency of the device. METHODS An explorative, pragmatic, prospective study design was conducted in two day hospital centres located in the northeast of Italy, from January 2011 to September 2012. Twenty patients who had skipped an appointment and were thus washing their TIVAD every eight weeks (exposed) were included, as were 17 patients following the typical wash regimen of every four weeks (controls). TIVAD occlusion-defined as the inability of the device to aspirate blood and/or the inability to properly irrigate the device-was the principal study end-point. RESULTS A total of six occlusions were documented in six patients. Four cases were observed among the exposed group (4/20; 20.0%), while two were observed among the control group (2/17; 11.7%). No statistically significant differences were observed in the occurrence of occlusion between the groups (RR: 1.29, 95%CI: 0.67-2.50, p = 0.49). No statistically significant differences emerged between groups in the time that elapsed from study inclusion to occlusion occurrence according to the time-to-event analysis performed using the Kaplan-Meier estimation model (Log Rank [Mantel-Cox] = χ(2) 0.284, df 1, p = 0.594). CONCLUSIONS Within the limitations of the study which should be addressed with further research based on double-blinded randomised clinical trials, postponing the irrigation regimen of TIVADs to eight weeks seems to be sufficient to maintain device patency.

Abstract
BACKGROUND Venous thrombo-embolic events (VTEs) occur in 2.2% to 14% of paediatric cancer patients and cause significant morbidity and mortality. The malignant disease itself, the cancer treatment and the presence of central venous catheters (CVCs) increase the risk of VTE. OBJECTIVES The primary objective of this review was to investigate the effects of preventive systemic treatments in paediatric cancer patients with tunnelled CVCs on (a)symptomatic VTE. Secondary objectives of this review were to investigate adverse effects of systemic treatments for the prevention of (a)symptomatic VTE in paediatric cancer patients with tunnelled CVCs; and to investigate the effects of systemic treatments in the prevention of (a)symptomatic VTE with CVC-related infection in paediatric cancer patients with tunnelled CVCs. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 8 2012), MEDLINE (1966 to August 2012) and EMBASE (1966 to August 2012). In addition, we searched reference lists from relevant articles and conference proceedings of the International Society for Paediatric Oncology (SIOP) (from 2006 to 2011), the American Society of Clinical Oncology (ASCO) (from 2006 to 2011), the American Society of Hematology (ASH) (from 2006 to 2011) and the International Society of Thrombosis and Haematology (ISTH) (from 2006 to 2011). We scanned the International Standard Randomised Controlled Trial Number (ISRCTN) Register and the National Institute of Health (NIH) Register for ongoing trials (www.controlled-trials.com) (August 2012), and we contacted the authors of eligible studies if additional information was required. SELECTION CRITERIA Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing systemic treatments to prevent venous thrombo-embolic events (VTEs) in paediatric cancer patients with tunnelled CVCs with a control intervention or no systemic treatment. For the description of adverse events, cohort studies were eligible for inclusion. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, extracted data and performed risk of bias assessment of included studies. Analyses were performed according to the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS Three RCTs and three CCTs (including 1291 children) investigated the prevention of VTE (low molecular weight heparin (LMWH) n = 134, antithrombin (AT) supplementation n = 37, low-dose warfarin n = 31, cryoprecipitate and/or fresh frozen plasma (FFP) supplementation n = 240, AT supplementation and LMWH n = 41). AT, cryoprecipitate and FFP were supplemented only in cases of AT or fibrinogen deficiency. Of the six included RCTs/CCTs, five investigated the prevention of VTE compared with no intervention (n = 737), and one CCT compared AT supplementation and LMWH with AT supplementation (n = 71). All studies had methodological limitations, and clinical heterogeneity between studies was noted.We found no significant effects of systemic treatments compared with no intervention in preventing (a)symptomatic VTE and no differences in adverse events (such as major and/or minor bleeding; none of the studies reported thrombocytopenia, heparin-induced thrombocytopenia (HIT), heparin-induced thrombocytopenia with thrombosis (HITT), death as a result of VTE, removal of CVC due to VTE, CVC-related infection, and post-thrombotic syndrome (PTS)) between experimental and control groups. Two studies with comparable participant groups and interventions were included for meta-analyses (n = 182). In the experimental group, 1/68 (1.5%) children were diagnosed with symptomatic VTE, as were 4/114 (3.5%) in the control group (best case scenario: risk ratio (RR) 0.65, 95% confidence interval (CI) 0.09 to 4.78). These studies also evaluated asymptomatic CVC-related VTE: In the experimental group, 22/68 (32.4%) were diagnosed with asymptomatic VTE, as were 35/114 (30.7%) in the control group (best case scenario: RR 1.02, 95% CI 0.40 to 2.55). Heterogeneity was substantial for this analysis: I(2) = 73%.The attribution of LMWH to AT supplementation resulted in a significant reduction in symptomatic VTE (Fisher's exact test, two-sided P = 0.028) without bleeding complications; asymptomatic VTE, thrombocytopenia, HIT, HITT, death as a result of VTE, removal of CVC due to VTE, CVC-related infection and PTS were not assessed.Four cohort studies were included for the evaluation of adverse events. Three studies provided information on bleeding episodes: One participant developed an ischaemo-haemorrhagic stroke. One study provided information on other adverse events: None occurred. AUTHORS' CONCLUSIONS We found no significant effects of systemic treatments compared with no intervention in preventing (a)symptomatic VTE in paediatric oncology patients with CVCs. However, this could be a result of the low number of included participants, which resulted in low power. In one CCT, which compared one systemic treatment with another systemic treatment, we identified a significant reduction in symptomatic VTE with the addition of LMWH to AT supplementation.All studies investigated the prevalence of major and/or minor bleeding episodes, and none found a significant difference between study groups. None of the studies reported thrombocytopenia, HIT, HITT, death as a result of VTE, removal of CVC due to VTE, CVC-related infection or PTS among participants.On the basis of currently available evidence, we are not able to give recommendations for clinical practise. Additional well-designed international RCTs are needed to further explore the effects of systemic treatments in preventing VTE. Future studies should aim for adequate power with attainable sample sizes. The incidence of symptomatic VTE is relatively low; therefore, it might be necessary to select participants with thrombotic risk factors or to investigate asymptomatic VTE instead.

Abstract
BACKGROUND The risk of developing a tunnelled central venous catheter (CVC)-related infection ranges between 0.1 and 2.3 per 1000 catheter days for children with cancer. These infections are difficult to treat with systemic antibiotics (salvage rate 24% - 66%) due to biofilm formation in the CVC. Lock treatments can achieve 100 - 1000 times higher concentrations locally without exposure to high systemic concentrations. OBJECTIVES Our objective was to investigate the efficacy of antibiotic and other lock treatments in the treatment of CVC-related infections in children with cancer compared to a control intervention. We also assessed adverse events of lock treatments. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, issue 3, 2011), MEDLINE/PubMed (1945 to August 2011) and EMBASE/Ovid (1980 to August 2011). In addition we searched reference lists from relevant articles and the conference proceedings of the International Society for Paediatric Oncology (SIOP) (from 2006 to 2010), American Society of Clinical Oncology (ASCO) (from 2006 to 2010), the Multinational Association of Supportive Care in Cancer (MASCC) (from 2006 to 2011), the American Society of Hematology (ASH) (from 2006 to 2010) and the International Society of Thrombosis and Haematology (ISTH) (from 2006 to 2011). We scanned the ISRCTN Register and the National Institute of Health Register for ongoing trials (www.controlled-trials.com) (August 2011). SELECTION CRITERIA Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing an antibiotic lock or other lock treatment (with or without concomitant systemic antibiotics) with a control intervention (other lock treatment with or without concomitant systemic antibiotics or systemic antibiotics alone) for the treatment of CVC-related infections in children with cancer. For the description of adverse events, cohort studies were also eligible for inclusion. DATA COLLECTION AND ANALYSIS Two authors independently selected studies, extracted data and performed 'Risk of bias' assessments of included studies. Analyses were performed according to the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS Two RCTs evaluated urokinase lock treatment with concomitant systemic antibiotics (n = 56) versus systemic antibiotics alone (n = 48), and one CCT evaluated ethanol lock treatment with concomitant systemic antibiotics (n = 15) versus systemic antibiotics alone (n = 13). No RCTs or CCTs evaluating antibiotic lock treatments were identified. All studies had methodological limitations and clinical heterogeneity between studies was present. We found no evidence of significant difference between ethanol or urokinase lock treatments with concomitant systemic antibiotics and systemic antibiotics alone regarding the number of participants cured, the number of recurrent CVC-related infections, the number of days until the first negative blood culture, the number of CVCs prematurely removed, ICU admission and sepsis. Not all studies were included in all analyses. No adverse events occurred in the five publications of cohort studies (one cohort was included in two publications) assessing this outcome; CVC malfunctioning occurred in three out of five publications of cohort studies assessing this outcome. AUTHORS' CONCLUSIONS No significant effect of urokinase or ethanol lock in addition to systemic antibiotics was found. However, this could be due to low power or a too-short follow-up. The cohort studies identified no adverse events; some cohort studies reported CVC malfunctioning. No RCTs or CCTs were published on antibiotic lock treatment alone. More well-designed RCTs are needed to further explore the effect of antibiotic or other lock treatments in the treatment of CVC-related infections in children with cancer.

Abstract
BACKGROUND Long-term central venous catheters have improved the quality of care for patients with chronic illnesses, but are complicated by obstructions which can result in delay of treatment or catheter removal. DESIGN AND METHODS This paper reviews thrombolytic treatment for catheter obstruction. Literature from Medline searches using the terms "central venous catheter", "central venous access device" OR "central venous line" associated with the terms "obstruction", "occlusion" OR "thrombolytic" was reviewed. Efficacy of thrombolytic therapy, central venous catheter clearance rates and time to clearance were assessed. RESULTS Alteplase, one of the current therapies, clears 52% of obstructed catheters within 30 min with 86% overall clearance (after 2 doses, when necessary). However, newer medications may have higher efficacy or shorter time to clearance. Reteplase cleared 67-74% within 30-40 min and 95% of catheters overall. Occlusions were resolved in 70 and 83% of patients with one and 2 doses of tenecteplase, respectively. Recombinant urokinase cleared 60% of catheters at 30 min and 73% overall. Alfimeprase demonstrated rapid catheter clearance with resolution in 40% of subjects within 5 min, 60% within 30 min, and 80% within 2 h. Additionally, urokinase prophylaxis decreased the incidence of catheter occlusions from 16-68% in the control group to 4-23% in the treatment group; in some studies, rates of catheter infections were also decreased in the urokinase group. CONCLUSIONS Thrombolytic agents successfully clear central venous catheter occlusions in most cases. Newer agents may act more rapidly and effectively than currently utilized therapies, but randomized studies with direct comparisons of these agents are needed to determine optimal management for catheter obstruction.

Abstract
In delivering safe care to their patients, oncology nurses should be familiar with the proper use and maintenance of implanted ports. Yet, despite the ubiquitous presence of implanted ports, accessing techniques and patency maintenance remain controversial. Additional research is needed to establish practices based on evidence.
