The incidence and risk factors of peripherally inserted central catheter-related infection among cancer patients

Establishment of a risk prediction model for peripherally inserted central catheter-related bloodstream infections based on a systematic review and meta-analysis of 20 cohorts

BACKGROUND

Peripherally inserted central catheters (PICCs) are commonly used for extended intravenous therapy but are associated with a significant risk of bloodstream infections (BSIs), which increase morbidity and healthcare costs.

AIM

The aim of this study was to identify patients at high risk of developing PICC-related bloodstream infections (PICC-RBSIs) to establish new and more specific targets for precise prevention and intervention.

METHODS

A search was conducted from the earliest available record to May 2024 among the following databases: Embase, MEDLINE, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, Scopus, and Chinese National Knowledge Infrastructure (CNKI). Hand searching for gray literature and reference lists of included papers was also performed. We assessed the quality of the studies using the Newcastle-Ottawa Scale (NOS) checklist. Two reviewers screened all the retrieved articles, extracted the data, and critically appraised the studies. Data analysis was performed using RevMan statistical software.

RESULTS

A total of 20 cohort studies involving 51,907 individuals were included in the analysis. The statistically significant risk factors identified were hospital length of stay, line type (tunneled), history of PICC placement, multiple lumens, previous infections, chemotherapy, total parenteral nutrition, hematological cancers, delays in catheter care, local signs of infection (e.g., localized rashes), previous BSIs, and diabetes mellitus. Due to high heterogeneity among studies regarding previous BSIs, this factor was excluded from the final predictive model, while all other risk factors were included.

CONCLUSIONS

The present meta-analysis identified risk factors for PICC-RBSIs and developed a predictive model based on these findings, incorporating 10 risk factors that integrate both patient-specific and procedural factors.

LINKING EVIDENCE TO ACTION

Integrating the risk prediction model for PICC-RBSI into clinical guidelines and training is essential. Healthcare providers should be trained to use this model to identify high-risk patients and implement preventive measures proactively. This integration could enhance personalized care, reduce infection incidence, and improve patient outcomes. Future research should update the model with new risk factors and validate its effectiveness in diverse clinical settings.

Role of the hemoglobin, albumin, lymphocyte, and platelet score in predicting thrombophlebitis among patients undergoing peripherally inserted central catheter

This study analyzes the role of the hemoglobin, albumin, lymphocyte, and platelet score (HALP), a pre-catheterization blood parameter, in predicting the occurrence of thrombophlebitis. We recruited 268 in-hospital patients who visited the Department of Oncology of our hospital and underwent peripherally inserted central catheter between January 2021 and January 2024. The cutoff value of the HALP score was defined using receiver's operating characteristic curve, and the differences were analyzed with log-rank test. The significance of HALP in predicting thrombophlebitis was evaluated using a multivariate Cox proportional hazards model. A total of 240 patients were enrolled and divided into a high-HALP (≥31.4) group (n = 125) and a low-HALP (<31.4) group (n = 115). The relationship between the composition of HALP and clinical pathological parameters was analyzed. HALP was significantly correlated with gender (X2 = 4.74), limb restriction (X2 = 3.69), performance status score (X2 = 11.9), D-dimer (X2 = 7.88), and platelet count (X2 = 5.22). Multivariate regression analysis found male (hazard ratio [HR] 0.29 (0.12-0.69)), more puncture times (HR 0.01 (0.001-0.15)), lower HALP (HR 1.93 (0.82-4.52)), and sterile couplant (HR 20.6 (4.7-91.2)) were independent factors affecting the occurrence of thrombophlebitis. Receiver's operating characteristic curve analysis showed the area under the curve of the HALP score was 0.718 (95% confidence interval 0.638-0.798), which was significantly larger than the other 3 parameters. Hence, we believe the predictive efficiency of HALP is higher than other parameters. The pre-catheterization HALP score can be used as a simple, accessible, and reliable tool for predicting thrombophlebitis in patients to undergo peripherally inserted central catheter.

Complication Rates of Peripherally Inserted Central Catheters in Oncologic Versus Non-Oncologic Patients

OBJECTIVES

Peripherally inserted central catheters are commonly used in cancer patients and provide vascular access for the administration of chemotherapy, antibiotics, or parenteral nutrition. Besides many advantages, they represent a source of possible complications such as catheter related blood stream infection, catheter occlusion, or thrombosis. In this study, the catheter-related complication rate between oncologic and non-oncologic patients was compared.

METHODS

This retrospective cohort-study included 411 patients who underwent their first catheter placement at the Vienna General Hospital-Medical University of Vienna from January 2013 to June 2018. Patient demographics and catheter-related parameters were collected and statistically analyzed using a competing risk model.

RESULTS

Mean catheter dwell time was 27.75 days. The overall complication rate was 7.54% (2.72 per 1000 catheter days). Underlying malignant disease (hazard ratio: 0.351, 95% confidence interval [CI]: 0.133-0.929, P = .035) and chemotherapy administration (hazard ratio: 2.837, 95% CI: 1.088-7.394, P = .033) were significantly associated with the occurrence of any kind of complication. Catheter related blood stream infection was observed among 11 (2.68%) patients and again significantly associated with chemotherapy administration (hazard ratio: 4.545, 95% CI: 1.178-17.539; P = .028). Thrombosis was found in 7 (1.70%) patients and occlusion in 13 (3.16%) cases.

CONCLUSIONS AND IMPLICATIONS FOR NURSING PRACTICE

Choice of venous access is an interdisciplinary decision with emphasis on patient participation. In oncologic patients, our data suggests that the benefits of peripherally inserted central catheters regarding costs, invasiveness, and accessibility might be outweighed by the higher rate of complications associated with the device. This becomes even more important in a community care setting, where standardized handling procedures and patient education play a pivotal role in device safety.

Peripherally Inserted Central Venous Catheter-Related Complications in Adult Patients with Haematological Malignancy

Background

Peripherally inserted central venous catheters (PICC) are widely used in patients with haematological malignancies owing to the requirement for prolonged intravenous therapy. However, the growing use of PICCs has resulted in a multitude of complications such as infections and thrombosis, leading to prolonged hospitalisation periods and increased morbidity. This study aimed to determine the incidence of and factors associated with PICC-related complications in patients with haematological malignancies.

Methods

This prospective cohort study was conducted at a single academic institution. The inclusion criteria involved all adult patients with haematological malignancies who had newly inserted PICCs. The patients were observed for a minimum duration of 60 days to evaluate the incidence of PICC-related infections and thrombosis, as well as mechanical complications.

Results

A total of 119 PICCs were implanted in 85 patients. Among them, more than half of the patients were diagnosed with lymphoma (55.0%). The median dwell time was 61 days (interquartile range: 98 days). The incidence of PICC-related complications was 58.0% (6.9 per 1,000 catheter-days). Specifically, 43 PICCs (36.1%, 4.3 per 1,000 catheter-days) experienced infective complications, 25 (21.1%, 2.5 per 1,000 catheter-days) encountered mechanical complications and 1 (0.8%, 0.1 per 1,000 catheter-days) exhibited thrombotic complications. Furthermore, an underlying diagnosis of acute leukaemia was significantly associated with a higher incidence of PICC-related infections.

Conclusion

Our study revealed higher incidence rates of PICC-related complications in adult patients with haematological malignancies compared to the finding of other studies. Notably, patients with underlying acute leukaemia displayed a higher incidence of PICC-related infections. These findings underscore the importance of implementing appropriate interventions and conducting thorough root cause analyses to effectively mitigate this complication and improve patient outcomes.

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.

The positioning of the catheter tip with an intracavitary electrocardiogram in epicutaneo-caval catheter placement via lower limbs in newborns: A retrospective study

OBJECTIVE

Few studies have been conducted on whether catheterisation via the lower limb pathway is suitable for intracavitary electrocardiogram (ECG) technology. This study explored the positioning of the epicutaneo-caval catheter (ECC) tip with intracavitary ECG via the lower limbs in newborns to determine its optimal placement and to improve the success rate of ECC placement using this method.

METHODS

Twenty-eight cases were selected for the observation group. The tip location with intracavitary ECG method was used to observe the changes in specific atrial depolarisation (P-wave) during the catheterisation process to determine whether the catheter tip was in the correct position. For comparative observation, chest X-rays and abdominal radiographs were taken within 24 h to determine sensitivity and specificity. The control group included 28 cases where the ECCs were inserted via the lower limbs, and chest X-rays and abdominal radiographs were taken within 24 h after the line was placed to confirm the correct positioning.

RESULTS

The success rate of the observation group was 91.30% (there were two cases of primary malposition), and the success rate of the control group was 78.57% (there were six cases of primary malposition). The success rate of the observation group was higher compared with the control group.

CONCLUSION

The tip location with intracavitary ECG method improved the success rate of ECC placement via the lower limbs in neonates. This method can effectively prevent the occurrence of lower limb primary catheter malposition and has significant clinical application value.

Single-Incision Plus One Port Laparoscopic Surgery for Myomectomy: A Retrospective Study

BACKGROUND

The purpose of this study was to evaluate the effect of single-incision plus one port laparoscopic surgery (SILS + 1) for myomectomy.

METHODS

We retrospectively analyzed data from patients who underwent laparoendoscopic single-site myomectomy (LESS-M group, n = 40) and SILS + 1 (SILS + 1-M group, n = 40) for myomectomy at our hospital from October 2018 through December 2020. The patients' baseline demographic information and clinical data were compared between the two groups.

RESULTS

The results showed that no significant difference in basic characteristics or between the number, size, and location of uterine myomas between the two groups (p < 0.05). However, the surgery was more difficult and the total operating time was significantly longer in the LESS-M group compared to the SILS + 1-M group (83.5 ± 14.2 vs. 108.2 ± 18.1 min, p = 0.001). Moreover, the estimated intraoperative blood loss (113.4 ± 46.5 vs. 211.4 ± 60.3 ml, p = 0.001) and changes in hemoglobin level (13.1 ± 7.6 vs. 18.2 ± 6.0, p = 0.001) were significantly lower in the SILS + 1-M group compared to the LESS-M group. In addition, no serious intraoperative or postoperative complications occurred after surgery in either group. The clinical outcomes in the SILS + 1-M group were associated with a significant reduction in total surgical time compared to the LESS-M group (p < 0.05).

CONCLUSION

SILS + 1 for myomectomy is popular in clinics, with a satisfactory clinical effect.

The Tip Position of Peripherally Inserted Central Catheters by the Sherlock 3CG System Was Almost Deeper Than Zone B: A Case Series

A first analysis of deaths due to central venous catheterization (CVC) in Japan in 2017 reported peripherally inserted central catheterization (PICC) as an alternative to CVC. In 2018, Sherlock™ 3CG (C.R. Bard Inc., New Jersey, USA) and Power PICC^® became available for use in Japan. The electromagnetic mechanism of the Sherlock 3CG system often eliminates the need for the use of fluoroscopic devices, such as C-arm scanners. In this clinical report, we describe five cases of patients who underwent PICC guided by the Sherlock 3CG system and were evaluated by transesophageal echocardiography (TEE). The patients were adapted for PICC for highly invasive urologic, thoracic, and dental surgery. Also, the positions of the catheter tip were confirmed by TEE in all cases. The mean distance from the access vein to the catheter tip was 41.1 ± 3.8 cm. Chest X-ray analysis showed a mean distance of 40.0 ± 21.5 mm between the carina and catheter tip. Bicaval TEE views showed that the Power PICC tip had not been advanced into the right atrium in any of the cases. We concluded that the tip positions of the Power PICC guided by the Sherlock 3CG system were almost deeper than Zone B and not in the right atrium.

Complications Associated with Peripherally Inserted Central Catheters (PICC) in People Undergoing Autologous Hematopoietic Stem Cell Transplantation (HSCT) in Home Hospitalization

INTRODUCTION

The SARS-CoV-2 pandemic generated the need to keep immunosuppressed patients away from hospital institutions for as long as possible. This in turn stimulated the implementation of a home hospitalization model for autologous hematopoietic stem-cell transplantation (HSCT).

PURPOSE

To analyze whether there are significant differences in post-transplantation complications related to catheters observed in patients treated in the home-transplant care modality compared to patients treated in the hospital.

METHODOLOGY

Observational, analytical, longitudinal, and retrospective study of cases and controls. A convenience sample was chosen, in which the cases comprised 20 patients included in the home HSCT care model. For each patient, it was considered suitable to propose two controls among those who received autologous transplantation in the last five years with a baseline demographic and pathological profile similar to the case for whom they were control.

RESULTS

The home patients achieved an average of 22.4 ± 2.6 days of evolution with an average of 16.4 ± 2.08 days post-transplant, compared to the hospital process with an average of 21.21 ± 4.18 days of evolution and 15.51 ± 3.96 days post-transplant (evolution days p = 0.022; post-transplant days p = 0.002). A higher percentage of use of parenteral nutrition (p = 0.036) and transfusions (p = 0.003) was observed during the post-transplant phase in the hospital. The rest of the therapeutic measures did not show significant differences. When analyzing the frequency of adverse effects in the post-transplant phase, a significant increase in neutropenic fever (OR = 8.55) and positive blood cultures (OR = 6.65) was observed in hospital patients. Any other significant differences in other variables related to PICC were found (presence and days of neutropenic fever, catheter infection, complications, pathogens, admission to the ICU, or death). Concerning local complications (pain, DVT, Medical adhesive-related Skin Injury, and erythema), there was more erythema in the hospital (p = 0.056).

CONCLUSIONS

The results obtained indicate that regarding the appearance of complications associated with PICCs in home hospitalization HSCT patients, there are no significant differences compared to hospitalization, so that home care can be a safe context for people with these lines.

Risk factors of catheter- associated bloodstream infection: Systematic review and meta-analysis

INTRODUCTION

The prevalence of catheter-associated bloodstream infections (CLABSI) is high and is a severe health problem associated with an increase in mortality and elevated economic costs. There are discrepancies related to the risk factors of CLABSI since the results published are very heterogeneous and there is no synthesis in the description of all the predisposing factors.

OBJECTIVE

We aimed to perform a systematic review and meta-analysis to synthesize and establish the risk factors predisposing to CLABSI reported in the literature.

METHOD

This is a systematic review of observational studies following the PRISMA recommendations. MEDLINE and CINAHL databases were searched for primary studies from 2007 to 2021. The protocol was registered in PROSPERO CRD42018083564.

RESULTS

A total of 654 studies were identified, 23 of which were included in this systematic review. The meta-analysis included 17 studies and 9 risk factors were analyzed (total parenteral nutrition (TPN), chemotherapy, monolumen and bilumen catheters, days of catheterization, immunosuppression, kidney disease and diabetes mellitus) due to the homogeneity of their definitions and measurements. The risk factors found to increase the probability of developing CLABSI were TPN, multilumen devices, chemotherapy treatment, immunosuppression and the number of days of catheterization. On the other hand, monolumen devices presented a lower likelihood of triggering this infection.

Occurrence rate and risk factors for long-term central line-associated bloodstream infections in patients with cancer: A systematic review

INTRODUCTION

Central line-associated bloodstream infection (CLABSI) is a public health problem that harms patients' outcomes and healthcare costs, especially in susceptible populations such as patients with cancer. Overall, systematic queries about etiology, risks, and epidemiology are explained by data from observational studies, which better underline the relationship between factors and incidence of disease. However, no recent systematic reviews of observational studies on adult patients with cancer have been conducted on this topic, considering the wide range of all potential factors which can contribute to the increase in infection rate in the hospitalized adults with cancer. This study systematically reviewed observational studies investigating the occurrence rate of CLABSI and its risk factors for long-term inserted central catheter-related infections in hospitalized adult cancer patients.

METHODS

A systematic review was performed on four databases from the earliest available date until December 2020. Retrospective and prospective cohort studies focused on the occurrence rate of CLABSI and its risk factors in hospitalized adult cancer patients. The pooled occurrence rate of CLABSI (95% CI) was calculated by applying a random-effects model.

RESULTS

Of 1712 studies, 8 were eligible, and the data of device-related infection rate were meta-analyzed. The pooled occurrence rate of CLABSI was roughly 8% (95% CI [4%, 14%]). The device characteristics, device's management aspects, therapies administration, and select patients' clinical conditions represent the main risk factors for long-term catheter-related infection in cancer patients.

LINKING EVIDENCE TO ACTION

Considering the substantial infection rate among cancer patients, identifying risk rate factors is pivotal to support evidence-grounded preventive strategies and maximize cancer patient safety. This study's results could guide policymakers and healthcare leaders and future research studies to disseminate appropriate risk-reducing management culture and implement standardized research and clinical approach to the investigated phenomenon as an infection surveillance strategy.

"With a PICC line, you never miss": The role of peripherally inserted central catheters in hospital care for people living with HIV/HCV who use drugs

BACKGROUND

People who use drugs (PWUD), and especially those who inject drugs, are at increased risk of acquiring bloodborne infections (e.g., HIV and HCV), experiencing drug-related harms (e.g., abscesses and overdose), and being hospitalized and requiring inpatient parenteral antibiotic therapy delivered through a peripherally inserted central catheter (PICC). The use of PICC lines with PWUD is understood to be a source of tension in hospital settings but has not been well researched. Drawing on theoretical and analytic insights from "new materialism," we consider the assemblage of sociomaterial elements that inform the use of PICCs.

METHODS

This paper draws on n = 50 interviews conducted across two related qualitative research projects within a program of research about the impact of substance use on hospital admissions from the perspective of healthcare providers (HCPs) and people living with HIV/HCV who use drugs. This paper focuses on data about PICC lines collected in both studies.

RESULTS

The decision to provide, maintain, or remove a PICC is based on a complex assemblage of factors (e.g., infections, bodies, drugs, memories, relations, spaces, temporalities, and contingencies) beyond whether parenteral intravenous antibiotic therapy is clinically indicated. HCPs expressed concerns about the risk posed by past, current, and future drug use, and contact with non-clinical spaces (e.g., patient's homes and the surrounding community), with some opting for second-line treatments and removing PICCs. The majority of PWUD described being subjected to threats of discharge and increased monitoring despite being too ill to use their PICC lines during past hospital admissions. A subset of PWUD reported using their PICC lines to inject drugs as a harm reduction strategy, and a subset of HCPs reported providing harm reduction-centred care.

CONCLUSION

Our analysis has implications for theorizing the role of PICC lines in the care of PWUD and identifies practical guidance for engaging them in productive and non-judgemental discussions about the risks of injecting into a PICC line, how to do it safely, and about medically supported alternatives.

Diagnostic accuracy among trainees to safely confirm peripherally inserted central catheter (PICC) placement using bedside ultrasound

BACKGROUND

Real-time utilization of ultrasound to confirm peripherally inserted central catheter (PICC) placement improves efficacy and reduces patient radiation exposure. We evaluated if novice ultrasound users could accurately confirm appropriate PICC tip location via ultrasound assessment.

METHODOLOGY

A prospective data collection study was conducted in an academic center with an established PICC team. Novice ultrasonography users performed 2 echocardiographic views (subcostal and apical 4 chamber) and noted position of visible wire. The presence of central bubbles (visualized in the heart) after a saline infusion, as well as time to bubbles (push-to-bubbles) seen in all patients, was also recorded. Image quality and confidence in imaging acquisition was also recorded.

RESULTS

Twenty-eight patients between ages 0 and 18 were enrolled over the study period with mean patient age of 10 years and median weight of 34 kg. The quality of image acquisition was rated as great only 34-44%. The wire was visualized only 25% of the time. The median push-to-bubble time when the PICC was later confirmed to be in appropriate positioning was 1.5 seconds with a delay of greater than 3 seconds 40% of the time when the line was malpositioned. The overall positive predictive value of ultrasound identifying malpositioned lines in this study was 43%.

CONCLUSIONS

With this PICC placement technique, ultrasound confirmation of PICC placement by novice ultrasound users was not superior to confirmation with chest radiograph. There may remain potential for future ultrasound protocols, with pediatric-specific technology or echogenic catheter tips, to reduce radiation exposure from chest radiograph during PICC line positioning verification.

Appropriateness of Replacing Fluoroscopic Guidance With ECG-Electromagnetic Guidance for PICC Insertion: A Randomized Controlled Trial

OBJECTIVE. Coupled ECG-electromagnetic (EM) guidance shows promise for use in placement of peripherally inserted central catheters (PICCs) when compared with the classic blind technique. However, ECG-EM guidance has not been appropriately compared with the reference standard of fluoroscopy (FX) guidance. Here, we aimed to compare ECG-EM guidance with FX guidance with regard to the final tip position of PICCs. SUBJECTS AND METHODS. A total of 120 patients (age range, 19-94 years) referred for PICC placement were randomized to the ECG-EM or FX group. All interventions were performed by PICC team members who had the same standardized training and experience. Final tip position was assessed using chest radiography and was classified as optimal, suboptimal, or inadequate requiring repositioning on the basis of the distance from the PICC tip to the cavoatrial junction (CAJ). Statistical analyses were performed using the Mann-Whitney U test for final catheter tip position (mean distance from CAJ) and Fisher and chi-square tests for proportions. RESULTS. PICCs were successfully inserted in 118 patients (53 men and 65 women). Catheter tip positions were optimal or suboptimal in 100% of the FX group and 77.2% of the ECG-EM group. Furthermore, precision of placement was significantly better (p = .004) in the FX group (mean distance from the PICC tip to the CAJ = 0.83 cm) than in the ECGEM group (mean distance from the PICC tip to the CAJ = 1.37 cm). Thirteen (22.8%) of the PICCs placed using ECG-EM guidance, all of which were inserted from the left side, were qualified as inadequate requiring repositioning and required another intervention. CONCLUSION. Our results revealed significant differences in final tip position between the ECG-EM and FX guidance techniques and indicate that ECG-EM guidance cannot appropriately replace FX guidance among unselected patients. However, ECGEM guidance could be considered as an acceptable technique for patients in whom the PICC could be inserted from the right side. TRIAL REGISTRATION. ClinicalTrials.gov NCT03652727.

Correlation of Positive Blood Cultures with Peripherally Inserted Central Catheter Line Infection in Oncology Patients

Introduction: The use of peripherally inserted central catheter (PICC) lines offers several advantages compared to traditional central venous catheters (CVCs) as the insertion procedure is minimally invasive, they may be retained safely for longer periods of time, and their use is associated with fewer catheter-related infections. Their use in patients suffering from a malignant disease is common but may pose a greater risk of complications due to the severe immunosuppression associated with treatment. This study was conducted to evaluate the safety of PICC lines in this group.

Methods: This was a retrospective study of oncology patients being treated in a Mediterranean tertiary center. Patients with PICC lines were enrolled in the study if a positive blood culture necessitated the removal of the PICC and subsequent culture of the PICC tip. A comparison was conducted between patients with positive and negative PICC cultures.

Results: Thirty patients were included, four of whom had a positive PICC culture. The most commonly isolated pathogens were coagulase-negative Staphylococci and Corynebacteria. No statistically significant difference was noted in white blood cell (WBC) counts, C-reactive protein (CRP), and Michigan PICC central line associated bloodstream infection (MPC) score between the two groups. Staphylococcus epidermidis was the most commonly isolated pathogen.

Discussion: Though limited by a small sample size and the retrospective design, the findings of this study seem to corroborate existing literature on the subject which suggests that the use of PICC lines in oncology patients is feasible and does not pose unacceptable risk. Further research is indicated to determine subgroups which may be at greater risk of PICC related infections.

Utilization and Complications of Central Venous Access Devices in Oncology Patients

Purpose: To describe how central venous access devices (CVADs) are utilized for ambulatory oncology patients and to evaluate the rate of complications. Method: Single institution retrospective study of oncology patients with CVADs who received systemic treatment at the Walker Family Cancer Centre (WFCC) between 1 January and 31 December 2018. Results: A total of 480 CVADS were placed in 305 patients, of which 408 (85%) were peripherally inserted central catheters (PICCs) and 72 (15%) were implanted vascular access devices (PORTs). The incidence of early and late complications was 9% and 24%, respectively. For the entire cohort, the rate of venous thromboembolism (VTE) was 16%, of which 9% were CVAD-related thrombosis (CRTs) and 7% were distant VTE. The CRT rates were similar for PICCs and PORTs (9% vs. 7%). A total of 6% of CVADs were complicated by infection (i.e., localized infections and bacteremia), with a total infection rate of 0.43 and 0.26 per 1000 indwelling days for PICCs and PORTs, respectively. The incidence of central line associated bloodstream infections (CLABSI) was greater for PICCs than PORTs, at a rate of 0.22 compared with 0.08 per 1000 indwelling days, respectively. The premature catheter removal rate was 26% for PICCs and 18% for PORTs. PORTs required more additional hospital visits. Conclusions: PICCs were utilized more frequently than PORTs and had a higher rate of premature removal. The rates of VTE and CRT were similar for both CVAD types. PORTs had a lower rate of infection per 1000 indwelling days. However, the management of PORT related complications required more visits to the hospital and oncology clinic.

The application of intracavitary electrocardiogram for tip location of femoral vein catheters in chemotherapy patients with superior vena cava obstruction

BACKGROUND

Most studies focused on the application of intracavitary electrocardiogram (IC-ECG) location in superior vena cava access catheterization, this study aimed to explore the effect of IC-ECG for tip location of femoral vein catheters in chemotherapy patients with superior vena cava obstruction (SVCO).

METHODS

A total of 158 patients placed catheters through superficial femoral vein from July 2016 to May 2019 were enrolled in the randomized controlled study. The patients were divided into two groups by envelope lottery method: X-ray location was used in the control group (n = 79); IC-ECG location was used in the observation group (n = 79). The catheters should be located at or near the inferior vena cava (IVC)-right atrium (RA) junction (above the level of diaphragm within the IVC). The general information of patients, clinical catheterization effects and catheter-related complications were compared between the groups.

RESULTS

No significant differences in general information, catheter obstruction, catheter-related thrombosis, catheter exit-site bleeding and infection were found between the groups. The rate of successful insertion at the first attempt and patient satisfaction in the observation group were significantly higher than that in the control group (p < 0.05). The time and cost of location and the incidence of catheter-related complications in the control group were 32.57 min and 140.51 Yuan and 21.5%, which were significantly higher than 6.94 min and 13.59 Yuan and 7.6% in the observation group (p < 0.05).

CONCLUSION

IC-ECG accurately located the tip of femoral vein catheters, reduced the incidence of catheter-related complications and the time and cost of location, improved patient satisfaction.

A longitudinal observational retrospective study on risk factors and predictive model of PICC associated thrombosis in cancer patients

To analyze the incidence of PICC associated venous thrombosis. To predict the risk factors of thrombosis. To validate the best predictive model in predicting PICC associated thrombosis. Consecutive oncology cases in 341 who initially naive intended to be inserted central catheter for chemotherapy, were recruited to our dedicated intravenous lab. All patients used the same gauge catheter, Primary endpoint was thrombosis formation, the secondary endpoint was infusion termination without thrombosis. Two patients were excluded. 339 patients were divided into thrombosis group in 59 (17.4%) and non-thrombosis Group in 280 (82.6%), retrospectively. Tumor, Sex, Age, Weight, Height, BMI, BSA, PS, WBC, BPC, PT, D-dimer, APTT, FIB, Smoking history, Location, Catheter length, Ratio and Number as independent variables were analyzed by Fisher's scoring, then Logistic risk regression, ROC analysis and nomogram was introduced. Total incidence was 17.4%. Venous mural thrombosis in 2 (3.4%), "fibrin sleeves" in 55 (93.2%), mixed thrombus in 2 (3.4%), symptomatic thrombosis in 2 (3.4%), asymptomatic thrombosis in 57 (96.6%), respectively. Height (χ² = 4.48, P = 0.03), D-dimer (χ² = 37.81, P < 0.001), Location (χ² = 7.56, P = 0.006), Number (χ² = 43.64, P < 0.001), Ratio (χ² = 4.38, P = 0.04), and PS (χ² = 58.78, P < 0.001), were statistical differences between the two groups analyzed by Fisher's scoring. Logistic risk regression revealed that Height (β = -0.05, HR = 0.95, 95%CI: 0.911-0.997, P = 0.038), PS (β = 1.07, HR = 2.91, 95%CI: 1.98-4.27, P < 0.001), D-dimer (β0.11, HR = 1.12, 95%CI: 1.045-1.200, P < 0.001), Number (β = 0.87, HR = 2.38, 95% CI: 1.619-3.512, P < 0.001) was independently associated with PICC associated thrombosis. The best prediction model, D-dimer + Number as a novel co-variable was validated in diagnosing PICC associated thrombosis before PICC. Our research revealed that variables PS, Number, D-dimer and Height were risk factors for PICC associated thrombosis, which were slightly associated with PICC related thrombosis, in which, PS was the relatively strongest independent risk factor of PICC related thrombosis.

Magnetic Tracking and Electrocardiography-Guided Tip Confirmation System Versus Fluoroscopy for Placement of Peripherally Inserted Central Catheters: A Randomized, Noninferiority Comparison

PURPOSE

To determine whether the use of a magnetic tracking and electrocardiography-guided catheter tip confirmation system (TCS) is safe and noninferior to fluoroscopy concerning positioning accuracy of a peripheral inserted central catheter (PICC).

METHODS

In this prospective, randomized, single-center study, adult patients scheduled for PICC insertion were assigned 1:1 either to TCS or fluoroscopy. The primary objective was a noninferiority comparison of correct PICC tip position confirmed by X-ray obtained immediately after catheter insertion. Time needed for PICC insertion and insertion-related complications up to 14 days after the procedure were secondary outcomes to be assessed for superiority.

RESULTS

A total of 210 patients (62.3 ± 14.4 years, 63.8% male) were included at a single German center between June 2016 and October 2017. Correct PICC tip position was achieved in 84 of 103 TCS (82.4%) and 103 of 104 fluoroscopy patients (99.0%). One-sided 95% lower confidence limit on the difference between proportions was -23.1%. Thus, noninferiority of TCS was not established (p > 0.99). Insertion of PICC took longer with TCS compared to fluoroscopy (8.4 ± 3.7 min vs. 5.0 ± 2.7 min, p < 0.001). Incidence of complications within a mean follow-up of 5.0 ± 2.3 days did not differ significantly between groups.

CONCLUSION

Noninferiority of TCS to fluoroscopy in the incidence of correct PICC tip position was not reached. Ancillary benefit of TCS over fluoroscopy including less radiation exposure and lower resource requirements may nonetheless justify the use of TCS. The study is registered with Clinical.Trials.gov (Identifier: NCT02929368).

Comparison of PICC and TIVAP in chemotherapy for patients with thyroid cancer

Peripherally inserted central catheters (PICC) and totally implantable venous-access ports (TIVAP) were compared in chemotherapy for patients with thyroid cancer. A retrospective analysis was performed on the clinical data of patients with thyroid cancer who were treated with PICC and TIVAP for chemotherapy in Qingdao Municipal Hospital from January 2013 to March 2018. Patients in the PICC and TIVAP groups were compared in terms of the success rate, indwelling time, complications, quality of life and nursing satisfaction. There was no statistically significant difference in the success rate between the two groups (P>0.05). The indwelling time in the TIVAP group was significantly longer than that in the PICC group (P<0.05). The incidence rate of complications in the TIVAP group (0%) was significantly lower than that in the PICC group (14.58%) (P<0.05). The quality of life score in the PICC group was significantly lower than that in the TIVAP group (P<0.05). There was no statistically significant difference in the nursing satisfaction score between the two groups (P>0.05). In conclusion, as an ideal venous access to chemotherapy for thyroid cancer, TIVAP has longer indwelling time and fewer adverse reactions and improves the quality of life of the patients.

Peripherally inserted central catheters: a hidden emerging cause of infection outbreaks

In our institution, between January 2010 and December 2017, 15 140 peripherally inserted central catheters (PICCs) were inserted in 12 314 patients. Using time-series analysis to evaluate the annual historical trend (AHT), we observed a significant increase in bloodstream infections (BSIs; AHT = 24; p < 0.001) and associated deaths (AHT = 3; p 0.02) in patient with PICCs. The risk of experiencing a BSI was significantly higher in patients with PICCs (odds ratio = 9.6; 95% confidence interval, 9.08–10.18; p < 0.001). To reduce PICC-related BSIs and their related mortality, it is important to limit the overuse of PICCs and to implement a ‘no PICC’ policy by limiting the insertion of PICCs to situations without other available options.

Febrile Neutropenia in Acute Leukemia. Epidemiology, Etiology, Pathophysiology and Treatment

Acute leukemias are a group of aggressive malignant diseases associated with a high degree of morbidity and mortality. An important cause of both the latter is infectious complications. Patients with acute leukemia are highly susceptible to infectious diseases due to factors related to the disease itself, factors attributed to treatment, and specific individual risk factors in each patient. Patients with chemotherapy-induced neutropenia are at particularly high risk, and microbiological agents include viral, bacterial, and fungal agents. The etiology is often unknown in infectious complications, although adequate patient evaluation and sampling have diagnostic, prognostic and treatment-related consequences. Bacterial infections include a wide range of potential microbes, both Gram-negative and Gram-positive species, while fungal infections include both mold and yeast. A recurring problem is increasing resistance to antimicrobial agents, and in particular, this applies to extended-spectrum beta-lactamase resistance (ESBL), Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE) and even carbapenemase-producing Enterobacteriaceae (CPE). International guidelines for the treatment of sepsis in leukemia patients include the use of broad-spectrum Pseudomonas-acting antibiotics. However, one should implant the knowledge of local microbiological epidemiology and resistance conditions in treatment decisions. In this review, we discuss infectious diseases in acute leukemia with a major focus on febrile neutropenia and sepsis, and we problematize the diagnostic, prognostic, and therapeutic aspects of infectious complications in this patient group. Meticulously and thorough clinical and radiological examination combined with adequate microbiology samples are cornerstones of the examination. Diagnostic and prognostic evaluation includes patient review according to the multinational association for supportive care in cancer (MASCC) and sequential organ failure assessment (SOFA) scoring system. Antimicrobial treatments for important etiological agents are presented. The main challenge for reducing the spread of resistant microbes is to avoid unnecessary antibiotic treatment, but without giving to narrow treatment to the febrile neutropenic patient that reduce the prognosis.

Influence of guide wire removal on tip location in peripherally inserted central catheters (PICCs): a retrospective cross-sectional study

OBJECTIVES

The aim of this study was to identify the prevalence of peripherally inserted central catheter (PICC) malposition and the influence of guide wire removal on tip location in PICCs and determine whether related factors, including age, sex, side of insertion and brand of catheter, influence the PICC tip location.

SETTING

Single-centre research institute in China recruiting patients from the hospital.

PARTICIPANTS

A total of 837 adult patients with inserted PICCs were recruited from October 2016 to May 2017.

INTERVENTIONS

This was a cross-sectional study aiming to identify the prevalence of PICC malposition and the influence of guide wire removal on tip location in PICCs. A linear regression model and a variance of factorial design analysis were performed. The PICC tip location was documented on a postinsertion chest X-ray. Multivariable analyses were performed based on the following related factors: age, sex, side of insertion and brand of catheter.

RESULTS

The tip location moved a mean of 17.4 mm among the 837 included patients. The prevalence of PICC malposition was 83.6% (700/837), while 16.4% (137/837) of PICCs remained in correct location. The mean movement caused by guide wire removal without an adjusted tail end was (-1.95±26.90) mm. The difference between tail end adjustment movement and actual tip position movement in each PICC was (33.0±17.1) mm in type C, which was significantly higher than the findings for type A (12.8±13.3) mm and type B (12.9±12.7) mm.

CONCLUSIONS

PICC malposition is a frequent event. Different catheter brands were associated with different ranges of movement in tip location after guide wire removal. The age and sex of the patients and the insertion side did not influence the extent of movement.

Can Peripherally Inserted Central Catheters Be Safely Placed in Patients with Cancer Receiving Chemotherapy? A Retrospective Study of Almost 400,000 Catheter-Days

BACKGROUND

Peripherally inserted central catheters (PICCs) are central venous catheters (CVCs) that are commonly used in onco-hematologic settings for chemotherapy administration. As there is insufficient evidence to recommend a specific CVC for chemotherapy administration, we aimed to ascertain PICC-related adverse events (AEs) and identify independent predictors of PICC removal in patients with cancer receiving chemotherapy.

MATERIALS AND METHODS

Information on adult patients with cancer with a PICC inserted for chemotherapy administration between September 2007 and December 2014 was extracted from six hospital databases. The primary outcome was PICC removal due to PICC-related AEs (occlusion, infection, or symptomatic thrombosis). Independent predictors of PICC removal were identified using a multivariate Cox regression model.

RESULTS

Among the 2,477 included patients, 419 PICC-related AEs (16.9%; 1.09 AEs per 1,000 PICC-days) were reported. AEs increased when PICC was inserted at the brachial site (hazard ratio [HR], 1.37; 95% confidence interval [CI], 1.02-1.84) and with open systems (HR, 1.89; 95% CI, 1.24-2.88) and decreased in older men (HR, 0.63; 95% CI, 0.49-0.81).

CONCLUSION

Use of PICC for chemotherapy administration was associated with a low all-AEs rate. The basilic vein was the safer site, and valved systems had fewer AEs than open systems. More research is needed to explore the interaction between AEs, sex, and age.

IMPLICATIONS FOR PRACTICE

These findings provide clinicians with evidence that peripherally inserted central catheters (PICCs) are safe for chemotherapy administration. They also suggest that clinicians should limit the use of open systems when long chemotherapy regimens are scheduled. Moreover, alternatives to PICCs should be considered when administering chemotherapy to young men.

The diagnostic value of intracavitary electrocardiogram for verifying tip position of peripherally inserted central catheters in cancer patients: A retrospective multicenter study

Purpose:

To evaluate the feasibility and accuracy of intracavitary electrocardiogram for verifying tip position of peripherally inserted central catheters in cancer patients during follow-up period.

Methods:

From March 2015 to October 2015, 126 patients involved in eight hospitals who underwent peripherally inserted central catheter placement received intracavitary electrocardiogram and chest X-ray to verify position of the catheter tip during follow-up period. Their intracavitary electrocardiogram was compared with surface electrocardiogram to judge catheter tip landing zone in one of three different anatomical zones. The amplitude of intracavitary electrocardiogram P wave and the ratio of intracavitary electrocardiogram P wave/surface electrocardiogram P wave were measured and showed correlation with catheter tip position confirmed by chest X-ray. Based on chest X-ray principle, all the cases were assigned into three intracavitary electrocardiogram groups to explore the optimal cut-off values for intracavitary electrocardiogram P wave and intracavitary electrocardiogram P wave/surface electrocardiogram P wave by analyzing the receiver operating characteristic.

Results:

No technique-related complications or adverse events occurred in this study. The matching rate between intracavitary electrocardiogram and chest X-ray method was 93.7%. The optimal cut-off values for intracavitary electrocardiogram P wave were set from 3.15 to 3.75 mV, and intracavitary electrocardiogram P wave/surface electrocardiogram P wave from 1.65 to 3.25.

Conclusions:

It is demonstrated in this retrospective multicenter study that the intracavitary electrocardiogram method for verifying tip position of peripherally inserted central catheter during follow-up period is feasible and accurate in all adult patients with cancer.

The safety and accuracy of ECG-guided PICC tip position verification applied in patients with atrial fibrillation

Background

Tip position verification of peripherally inserted central catheters (PICCs) is essential to the use of the catheter. Postprocedural chest X-ray as the “gold standard” practice for PICC tip confirmation can lead to a significant delay for patient IV therapy, cost more, and lead to radiation exposure for both patients and staffs. Intracavitary electrocardiogram (IC-ECG)-guided PICC placement which provides real-time tip confirmation during the insertion procedure has been widely used. However, safety and accuracy of ECG for abnormal surface ECG patients, such as patients with atrial fibrillation (AF), have not been reported.

Objective

To determine the safety and accuracy of IC-ECG technique for PICC tip position verification among the patients with AF.

Patients and methods

A prospective cohort study was conducted in a teaching and tertiary referral hospital with more than 3,600 beds in Qingdao, People’s Republic of China. Adult patients with diagnosis of AF who need a PICC for infusion from June 2015 to May 2017 were enrolled in the study. For every included patient with AF, ECG was used to detect the PICC tip position during catheterization and X-ray was done to confirm the tip position as the “gold standard” after PICC insertion. The effectiveness and accuracy of ECG-guided catheter tip positioning and chest X-ray confirmation were compared.

Results

Totally, 118 AF patients with 118 PICCs were enrolled (58 male and 60 female, age range 50–89 years old). There was no catheterization-related complication. When the catheter entered the lower 1/3 of superior vena cava, the amplitude of f wave reached the maximum. There was no statistical difference between X-ray PICC tip position verification and IC-ECG PICC tip position verification among patients with AF (χ²=1.31, P=0.232). Utilizing the cutoff point of f wave change ≥0.5 cm, a sensitivity of 0.94, a specificity of 0.71, a positive predictive value of 0.98, and a negative predictive value of 0.42 were observed. The area under the receiver operating characteristic curve was 0.909 (95% CI: 0.810–1.000).

Conclusion

The ECG-guided technique represents a safe and accurate technique to verify the position of PICC tip in patients with AF and could potentially remove the requirement for postprocedural chest X-ray among the patients with AF.

The microbiological characteristics and risk factors for PICC-related bloodstream infections in intensive care unit

The study was aimed to investigate the pathogens distribution and risk factors for PICC-related bloodstream infection in intensive care unit (ICU) patients. 402 patients placed with PICC in ICU were recruited in the study. The microbiological characteristics of PICC-related infection were investigated by Vitek 2 Compact automated microbial system. Antibiotics sensitivity was performed with disk diffusion and minimum inhibitory concentration (MIC) methods. Multivariate logistic and cox analyses were performed to identify the risk factors for PICC-related infection in ICU patients. 38 PICC-related infection cases were observed, and its morbidity was 9.45%. The morbidity was significantly higher in power PICC cases than that in common PICC cases. Gram-positive bacteria might be responsible for the major infection cases, followed by gram-negative bacteria, and fungi. Drug sensitivity analyses indicated that gram-negative bacteria showed low resistance to carbapenems antibiotics, and Cefperazone/sulbactam. The gram-positive bacterial exhibited sensitive to Teicoplanin and Vancomycin. The isolated fungi showed low resistance to the commonly used antifungal antibiotics. Multivariate analyses demonstrated that power PICC, high Charison scores, diabetes mellitus, double lumens triple lumens were risk factors for PICC-related infections among ICU patients. Power PICC, high Charison scores, diabetes mellitus, multi-lumens are risk factors for PICC-related bloodstream infection in ICU patients.

Superior success rate of intracavitary electrocardiogram guidance for peripherally inserted central catheter placement in patients with cancer: A randomized open-label controlled multicenter study

Background

Intracavitary electrocardiogram (IC ECG) guidance emerges as a new technique for peripherally inserted central catheters (PICCs) placement and demonstrates many potential advantages in recent observational studies.

Aims

To determine whether IC ECG-guided PICCs provide more accurate positioning of catheter tips compared to conventional anatomical landmarks in patients with cancer undergoing chemotherapy.

Methods

In this multicenter, open-label, randomized controlled study (ClinicalTrials.gov number, NCT02409589), a total of 1,007 adult patients were assigned to receive either IC ECG guidance (n = 500) or anatomical landmark guidance (n = 507) for PICC positioning. The confirmative catheter tip positioning x-ray data were centrally interpreted by independent radiologists. All reported analyses in the overall population were performed on an intention-to-treat basis. Analyses of pre-specified subgroups and a selected large subpopulation were conducted to explore consistency and accuracy.

Results

In the IC ECG-guided group, the first-attempt success rate was 89.2% (95% confidence interval [CI], 86.5% to 91.9%), which was significantly higher than 77.4% (95% CI, 73.7% to 81.0%) in the anatomical landmark group (P < 0.0001). This trend of superiority of IC ECG guidance was consistently noted in almost all prespecified patient subgroups and two selected large subpopulations, even when using optimal target rates for measurement. In contrast, the superiority nearly disappeared when PICCs were used via the left instead of right arms (interaction P-value = 0.021). No catheter-related adverse events were reported during the PICC intra-procedures in either group.

Conclusions

Our findings indicated that the IC ECG-guided method had a more favorable positioning accuracy versus traditional anatomical landmarks for PICC placement in adult patients with cancer undergoing chemotherapy. Furthermore, there were no significant safety concerns reported for catheterization using the two techniques.

Femorally inserted central venous catheter in patients with superior vena cava obstruction: choice of the optimal exit site

PURPOSE

This study assessed patient comfort and catheter indwelling time and decreased incidence of complications in patients with femorally inserted venous catheters (FIVCs) via different exit sites.

METHODS

A group of 114 patients suffering from lung cancer complicated by superior vena cava obstruction (SVCO) underwent femoral insertion of venous catheters to facilitate chemotherapy infusion. Patients were divided into two groups: a novel (NOV) group (n = 59) with the FIVC exit site at the mid-thigh and a conventional (CON) group (n = 55) with the exit site at the groin. The clinical efficacy and safety were compared.

RESULTS

There were significant differences (p&lt;0.001) between NOV and CON groups in bleeding scores (2.44 ± 0.62 vs. 1.36 ± 0.49), catheter indwelling time (195.08 ± 39.19 days vs. 91.53 ± 32.88 days), patient comfort scores (4.20 ± 0.87 vs. 1.35 ± 0.91), and pain scores (1.64 ± 0.91 vs. 2.42 ± 1.08). Significant differences (p&lt;0.05) were also observed in catheter-associated thrombosis (1.69% vs. 14.55%), catheter exit site infection (1.69% vs. 21.82%), and the incidence of total complications (11.86% vs. 45.45%) between the NOV and CON groups. However, the differences in success rates between the NOV and CON groups during the first attempt (98.32% vs. 98.18%) and catheter obstruction (8.48% vs. 9.09%) were not significant (p&gt;0.05).

CONCLUSIONS

Compared with the conventional exit site at the groin, the exit site at the mid-thigh for FIVCs increased patients' comfort and catheter indwelling time, and decreased the rate of complication and pain scores. However, it did not decrease the success rate in SVCO patients.

Defining the Specialty of Vascular Access through Consensus: Shaping the Future of Vascular Access

The Association for Vascular Access (AVA) is an organization of health care professionals founded in 1985 to support and promote the specialty of vascular access. The mission of AVA is to distinguish the vascular access specialty and define standards of vascular access through an evidence-based approach designed to enhance health care. There is little guidance for multidisciplinary procedures/practice, and this is the case for vascular access. There are also inconsistencies and conflicts in terminology. Additionally, there is no consensus of vascular access as a specialty. It is the focus of AVA to promote consistency in vascular access practice. This document embraces a common title for a clinician with knowledge and skills in the area of vascular access. This establishes a new paradigm that will strengthen the advancement of the vascular access specialty.

Bloodstream infections in neutropenic cancer patients: A practical update

Bloodstream infections (BSI) are among the most frequent complications in neutropenic cancer patients and, if caused by Gram-negative rods, are associated with high mortality. Thus, fever during neutropenia warrants prompt empirical antibiotic therapy which should be active against the most frequent Gram-negatives. In the last decade, there has been a worldwide increase in multidrug resistant (MDR) strains. In these cases, the traditional choices such as oral therapy, ceftazidime, cefepime, piperacillin-tazobactam, or even carbapenems, might be ineffective. Therefore novel de-escalation approach has been proposed for patients who are at high risk for infections due to MDR bacteria. It consists of starting antibiotics which cover the most probable resistant strain but it is narrowed down after 72 hours if no MDR pathogen is isolated. With increasing bacterial resistance, the benefit of fluoroquinolone prophylaxis during prolonged neutropenia remains to be confirmed. Antibiotic stewardship and infection control programs are mandatory in every cancer center.
