Comparison of complication rates and incidences associated with different peripherally inserted central catheters (PICC) in patients with hematological malignancies: a retrospective cohort study

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.

Uncertainty affects cancer-related fatigue among breast cancer women undergoing peripherally inserted central catheter chemotherapy: the chain mediating role of psychological resilience and self-care

BACKGROUND

Breast cancer patients undergoing chemotherapy via peripherally inserted central catheter often experience serious behavioral and psychological challenges, with uncertainty and cancer-related fatigue being prevalent issues that profoundly impact prognosis. Therefore, this study aimed to investigate the relationship between uncertainty and cancer-related fatigue by employing a chain mediation model to examine the potential mediating roles of psychological resilience and self-care.

METHODS

A cross-sectional study was conducted with 223 breast cancer patients receiving peripherally inserted central catheter chemotherapy at two tertiary affiliated hospitals of China Medical University in Liaoning, China, from February 2021 to December 2022. Participants completed self-reported questionnaires to assess uncertainty, psychological resilience, self-care, and cancer-related fatigue. The collected data were subsequently analyzed using Pearson's correlation analysis, hierarchical regression analysis, and mediation analysis.

RESULTS

Uncertainty exhibited a significant positive correlation with cancer-related fatigue (p < 0.01) and a negative correlation with psychological resilience (p < 0.01) and self-care (p < 0.01). Uncertainty was found to impact cancer-related fatigue through three pathways: psychological resilience mediated the relationship between uncertainty and cancer-related fatigue (mediating effect = 0.240, 95% confidence interval: 0.188 to 0.298, effect ratio = 53.22%); self-care also mediated this relationship (mediating effect = 0.080, 95% confidence interval: 0.044 to 0.121, effect ratio = 17.74%); furthermore, there was a significant joint mediating effect of psychological resilience and self-care on the association between uncertainty and cancer-related fatigue (mediating effect = 0.042, 95% confidence interval: 0.021 to 0.068, effect ratio o = 9.31%).

CONCLUSION

The findings of this study revealed that uncertainty not only directly influenced cancer-related fatigue, but also operated through the mediating effect of psychological resilience, self-care, and sequential mediation of psychological resilience and self-care. Interventions tailored for breast cancer patients receiving peripherally inserted central catheter chemotherapy should target these factors to help alleviate uncertainty, enhance psychological resilience, and improve self-care practices, thereby ameliorating cancer-related fatigue.

A feasible and safe standardized protocol for ultrasound and intracavitary electrocardiogram-based tip navigation and tip location during placement of peripherally inserted central catheters

BACKGROUND

Peripherally inserted central catheters (PICCs) are performed for medium and long term intravenous therapy. The most recent guidelines recommend the use of ultrasound-guided venipuncture to reduce surgery-related complications. In recent years, bedside ultrasound has also been used as evidence of accuracy in tip navigation and tip positioning. This paper is aimed to investigate using tip navigation with the ultrasonic technique and intracavitary electrocardiogram during the catheterization, and to suggest a feasible and safe standardized protocol for clinical practice.

METHODS

A total of 1727 tumor clients who suffered from combined the ultrasonic technique with intracavitary electrocardiogram (ECG + US group) to confirm the tip location of PICC were included in Peking Union Medical College Hospital in 2020. And based on electronic medical records according to the types of cancer as 1:1 to select 1727 cases who only underwent electrocardiogram (ECG group) to verify the tip location of catheters with the same team in 2019. Compared two groups of purpose of catheter, insertion site of upper limbs, times of puncture and delivery catheters, tip location and malposition of peripherally inserted central catheter, and analysis of the safety and feasibility.

RESULTS

There were no significant differences between the two groups in the purpose of catheter, insertion site of upper limbs, times of puncture, and delivery catheters. The percentage of optimal tip location in ECG + US group was significantly higher than that in ECG group, and the rate of malposition of catheters was obviously lower than that in ECG group (p < 0.001).

CONCLUSIONS

Tip navigation based with ultrasound and intracavitary electrocardiogram has high accuracy to confirm tip location of PICC, and it is also feasible and safe, which can not only to make up for the deficiency of patients without surface P waves who could not be applied ECG but also to fit for all patients.

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

BACKGROUND

Lack of agreed terminology and definitions in healthcare compromises communication, patient safety, optimal management of adverse events, and research progress. The purpose of this scoping review was to understand the terminologies used to describe central venous access devices (CVADs), associated complications and reasons for premature removal in people undergoing cancer treatment. It also sought to identify the definitional sources for complications and premature removal reasons. The objective was to map language and descriptions used and to explore opportunities for standardisation.

METHODS

A systematic search of MedLine, PubMed, Cochrane, CINAHL Complete and Embase databases was performed. Eligibility criteria included, but were not limited to, adult patients with cancer, and studies published between 2017 and 2022. Articles were screened and data extracted in Covidence. Data charting included study characteristics and detailed information on CVADs including terminologies and definitional sources for complications and premature removal reasons. Descriptive statistics, tables and bar graphs were used to summarise charted data.

RESULTS

From a total of 2363 potentially eligible studies, 292 were included in the review. Most were observational studies (n = 174/60%). A total of 213 unique descriptors were used to refer to CVADs, with all reasons for premature CVAD removal defined in 84 (44%) of the 193 studies only, and complications defined in 56 (57%) of the 292 studies. Where available, definitions were author-derived and/or from national resources and/or other published studies.

CONCLUSION

Substantial variation in CVAD terminology and a lack of standard definitions for associated complications and premature removal reasons was identified. This scoping review demonstrates the need to standardise CVAD nomenclature to enhance communication between healthcare professionals as patients undergoing cancer treatment transition between acute and long-term care, to enhance patient safety and rigor of research protocols, and improve the capacity for data sharing.

Global impact of antibacterial resistance in patients with hematologic malignancies and hematopoietic cell transplant recipients

Patients with hematologic malignancies and hematopoietic cell transplant (HCT) recipients are at high risk of developing bacterial infections. These patients may suffer severe consequences from these infections if they do not receive immediate effective therapies, and thus are uniquely threatened by antimicrobial-resistant bacteria. Here, we outline how the emergence of specific resistant bacteria threatens the effectiveness of established approaches to prevent and treat infections in this population. The emergence of fluoroquinolone resistance among Enterobacterales and viridans group streptococci may decrease the effectiveness of fluoroquinolone prophylaxis during neutropenia. The emergence of Enterobacterales that produce extended-spectrum β-lactamases or carbapenemases and of increasingly resistant Pseudomonas aeruginosa may result in neutropenic patients experiencing delayed time to active antibacterial therapy, and consequently worse clinical outcomes. The ability to select targeted antibacterial therapies after the availability of susceptibility data may be limited in patients infected with metallo-β-lactamase-producing Enterobacterales and difficult-to-treat P. aeruginosa. Vancomycin-resistant enterococci and Stenotrophomonas maltophilia can cause breakthrough infections in patients already being treated with broad-spectrum β-lactam antibiotics. Resistance can also limit the ability to provide oral stepdown antibacterial therapy for patients who could otherwise be discharged from hospitalization. We also outline strategies that have the potential to mitigate the negative impact of antimicrobial resistance, including interventions based on active screening for colonization with resistant bacteria and the use of novel rapid diagnostic assays. Additional research is needed to better understand how these strategies can be leveraged to combat the emerging crisis of antimicrobial resistance in patients with hematologic malignancies and HCT recipients.

Making a difference? A retrospective review of peripherally inserted central catheters: A single-center experience in Colombia

Introduction

Peripherally inserted central catheters (PICCs) are an effective tool as a medical device in patients who require them. However, it is a procedure that has been associated with multiple complications and possible negative outcomes for the health of the patients. This paper seeks to describe the main complications derived from the insertion and maintenance of peripherally inserted central venous catheters (PICCs), based on the experience of a vascular accesses group in a cardiovascular center in Colombia.

Methods

A retrospective cross-sectional analytical study of the adult population undergoing PICC insertion at the Fundación Cardioinfantil-Instituto de Cardiología, during the period between 2019 and 2020 by the vascular access program, was performed.

Results

The frequency of any registered complication was 15.9% for 2019 and 11.2% for 2020. Bleeding at the procedure site occurred in 15.3% during 2019 and 7.0% in 2020, making it the most frequent complication during the procedure. All the variables of complications associated with infection (bacteremia, phlebitis, and catheter-related infection) showed a decrease in 2020 compared to the previous year. The central line-associated bloodstream infection registered for the year 2019 was 1.94 bacteremia's/1000 catheters-day compared to 0.29 bacteremia's/1000 catheters-day.

Conclusions

There has been a 4.7% reduction in the frequency of any registered complication after the implementation of the vascular access groups. Global and specific complications decreased significantly from 2019 to 2020. Notably, bacteremia, a common post-procedure complication, showed a substantial decrease in frequency compared to national and worldwide literature. It is also been described that complications associated with infection showed a decrease in 2020 compared to 2019. Whether or not all these findings are directly or somewhat related to the results stemming from the vascular access groups still needs further investigation.

Peripherally inserted central catheters can be an alternative to tunneled central venous catheters in chemotherapy for hematological and oncological pediatric patients

PURPOSE

Tunneled central venous catheters (TCVs) are commonly used for pediatric chemotherapy. Recently, peripherally inserted central catheters (PICCs) have been used instead. Although PICC has the advantages of simpler insertion and fewer severe complications, there is little information on the efficacy of PICC compared to TCV in pediatric chemotherapy.

METHODS

Patients, aged younger than 18 years, with primary malignancy who received chemotherapy with PICC or TCV at our institution from December 2007 to August 2022 were included in the study. We retrospectively compared PICC and TCV using medical records.

RESULTS

Within the observation period, 133 catheters (73 PICCs and 60 TCVs) were inserted. The median indwelling time was 99 days for PICCs and 182 days for TCVs, with TCVs being significantly longer (p < 0.001). There were no significant differences in the incidence of complications, such as infections, thrombosis, obstruction, or mechanical accidents. Comparing patients treated with PICC (PICC group) versus those with TCV (TCV group), the time from diagnosis to insertion was significantly shorter in the PICC group (p < 0.001). In the PICC group, none of the patients required general anesthesia, and chemotherapy was completed with PICC only.

CONCLUSION

PICC can be an alternative to TCV in pediatric chemotherapy.

The clinical topography of peripherally inserted central catheter-related thrombosis in cancer patients: A prospective and longitudinal observational study based on ultrasound scans every two days

AIMS

To delineate the clinical topography of peripherally inserted central catheter (PICC)-related thrombosis in cancer patients.

BACKGROUND

Most of the clinical features of PICC-related thrombosis are based on a single follow-up, which is insufficient to reflect the full topography of a thrombosis.

DESIGN

This is an observational study conducted at West China Hospital, according to the STROBE guidelines.

METHODS

Cancer patients scheduled for PICC placement were potentially eligible; patients with contraindications to PICC placement or existing diseases affecting blood flow were excluded; and those who later withdrew or did not reply to our contact request during the follow-up period were eliminated from this study. Ultrasound was used to detect thrombosis from the insertion site, proximal insertion site, axillary vein to the subclavian vein once every two days for two weeks post insertion. The thrombosis and its involved venous segments, onset time and symptoms and signs were recorded.

RESULTS

Among the 173 included patients, 126 (72.8 %) were identified as having thrombosis. Specifically, 113 and 126 patients were identified as having thrombosis within the first three days and the first week post insertion, respectively. In the 126 patients, thrombosis occurred at the insertion site (72.8 %) concurrently with thrombosis at the proximal insertion site (n = 120, 69.4 %), thrombosis in the axillary vein (n = 94, 54.3 %), and/or thrombosis in the subclavian vein (n = 41, 23.7 %). The log-rank test demonstrated that thrombosis in these four venous segments decreased significantly from the distal to the proximal central vein (log-rank test = 117.128, P < .001). Of 31 patients (17.9 %) who presented symptomatic thrombosis, only five patients experienced obvious swelling in the upper arm, and the other 26 patients exhibited atypical symptoms, such as soreness, tightness, numbness, tingling, or other discomforts in the palm, arm, armpit, and/or shoulder. In some thrombotic cases, ultrasonic assessment of PICC-related thrombosis did not parallel clinical symptoms and signs.

CONCLUSION

PICC-related thrombosis is common and can occur very early post insertion in cancer patients, and most thromboses present atypical symptoms. More than half of the cases with thrombosis evaluated involve multiple venous segments, and the farther the venous segments are from the central vein, the higher the incidence of thrombosis tend to be and the earlier the onset time are.

RELEVANCE TO CLINICAL PRACTICE

The results highlight the importance that medical staff pay particular attention to patients with catheters in the first week post insertion and be alert to thrombosis presenting atypical symptoms while keeping in mind that clinical symptoms and signs are not reliable for diagnosing thrombosis.

Peripherally Inserted Central Venous Catheter (PICC) Related Bloodstream Infection in Cancer Patients Treated with Chemotherapy Compared with Noncancer Patients: A Propensity-Score-Matched Analysis

The use of peripherally inserted central catheters (PICCs) has increased in cancer patients. This study aimed to compare the incidence of PICC-related bloodstream infections (PICCR-BSIs) in cancer patients treated with chemotherapy and in noncancer patients. We performed a secondary analysis from a retrospective, single-center, observational cohort. The PICCR-BSI incidence rates in cancer and noncancer patients were compared after 1:1 propensity-score matching. Then, the factors associated with PICCR-BSI were assessed in a Cox model. Among the 721 PICCs (627 patients) included in the analysis, 240 were placed in cancer patients for chemotherapy and 481 in noncancer patients. After propensity-score matching, the PICCR-BSI incidence rate was 2.6 per 1000 catheter days in cancer patients and 1.0 per 1000 catheter days in noncancer patients (p < 0.05). However, after adjusting for variables resulting in an imbalance between groups after propensity-score matching, only the number of PICC lumens was independently associated with PICCR-BSI (adjusted hazard ratio 1.81, 95% confidence interval: 1.01-3.22; p = 0.04). In conclusion, the incidence rate of PICCR-BSI is higher in cancer patients treated with chemotherapy than in noncancer patients, but our results also highlight the importance of limiting the number of PICC lumens in such patients.

Clinical factors associated with peripherally inserted central catheters (PICC) related bloodstream infections: a single centre retrospective cohort

BACKGROUND

Despite their spread in daily practice, few data is available on clinical factors associated with peripherally inserted central catheter (PICC)-related bloodstream infections (PR-BSI). We aimed to assess the PR-BSI incidence, microbiology, and factors associated with PR-BSI with a focus on clinical symptoms.

METHODS

We conducted a retrospective cohort study in a French university hospital. We screened all PICC insertions performed from April 1st, 2018, to April 1st, 2019, and included PICC insertions in adult patients. We assessed the PR-BSI incidence, the factors associated with PR-BSI using a Cox model, and negative and positive predictive values (NPVs and PPVs) of each clinical sign for PR-BSI.

RESULTS

Of the 901 PICCs inserted in 783 patients (38,320 catheters days), 214 PICCs (24%) presented with a complication. The most prevalent complication was PR-BSI (1.9 per 1000 catheter days; 8.1% of inserted PICCs ). Enterobacterales (N = 27, 37%) and coagulase negative Staphylococci (N = 24, 33%), were the main microorganisms responsible for PR-BSI. Factors independently associated with occurrence of PR-BSI were fever (hazard ratio 13.21, 95% confidence interval 6.00-29.11, p < 0.001) and chills (HR 3.66, 95%CI 1.92-6.99, p < 0.001). All clinical signs and a duration of PICC maintenance ≥ 28 days, had a low PPVs (≤ 67.1%) but high NPVs (≥ 92.5%) for PR-BSI.

CONCLUSIONS

Monitoring of clinical signs, especially fever and chills, with caution and limitation of device maintenance duration, could improve PICC management.

Impact of number of lumens in central-venous catheters on central-line bloodstream infection (CLABSI) and venous thromboembolism (VTE) risk in patients with acute leukemia

This retrospective study was conducted to determine whether the number of peripherally inserted central-catheter lumens affected the rate of central-line associated bloodstream infections (CLABSIs) in adult patients with acute leukemia. The results show that CLABSI rates were not significantly different between patients with triple-lumen or double-lumen PICCs (22.1% vs 23.4%; P = .827).

Symptomatic Deep Vein Thrombosis Associated With Peripherally Inserted Central Catheters of Different Diameters: A Systematic Review and Meta-Analysis

We assessed the relationship between peripherally inserted central catheter (PICC) diameters and symptomatic deep vein thrombosis (DVT) rates. We conducted a systematic search for articles published between 2010 and 2021 reporting DVT incidence by catheter diameter in patients who had a PICC, followed by meta-analyses for DVT risk in each diameter group. Pooled DVT rates were incorporated into an economic model. Of 1627 abstracts screened, 47 studies were included. The primary meta-analysis of 40 studies demonstrated the incidence of DVT was 0.89%, 3.26%, 5.46%, and 10.66% for 3, 4, 5, and 6 French (Fr) PICCs (P  =  .01 between 4 and 5 Fr). Rates of DVT were not significantly different between oncology and nononcology patients (P  =  .065 for 4 Fr and P  =  .99 for 5 Fr). The DVT rate was 5.08% for ICU patients and 4.58% for non-ICU patients (P  =  .65). The economic model demonstrated an annual, incremental cost savings of US$114 053 for every 5% absolute reduction in 6 Fr PICCs use. Using the smallest PICC that meets the patients' clinical needs may help to mitigate risks and confer savings.

Benefits of an online multimodal nursing program among patients with peripherally inserted central catheter-related thrombosis

Background

Asymptomatic peripherally inserted central catheter-related thrombosis (PICC-RT) is one of the most common and dangerous complications caused by peripherally inserted central catheter (PICC) insertion. A variety of factors might lead to huge psychological pressures on patients and markedly affect their quality of life. The aim of this study was to evaluate the benefits of an online multimodal nursing program on the quality of life and psychological resilience of asymptomatic PICC-RT patients with ovarian cancer.

Methods

This was a prospective cohort study on patients with asymptomatic PICC-RT. Patients in the control group received routine nursing care, while patients in the intervention group obtained extra assistance through an online multimodal nursing program. Individual guidance, psychological support, and real-time consultation were provided to patients in the intervention group. All participants were followed for 3 months. The health-related quality of life and psychological resilience of patients were evaluated by using the 36-item Short Form Health Survey (SF-36) and Connor-Davidson Resilience Scale (CD-RISC), respectively.

Results

Compared to baseline, most of the items in the SF-36 scores were significantly increased in both intervention and control groups after 3 months (all p < 0.05), except for the role emotional domain (p = 0.085 in control group). However, the SF-36 scores of the intervention group were significantly higher than those of the control group in All health domains, including physical functioning (p = 0.001), role physical (p = 0.004), bodily pain (p = 0.003), general health (p < 0.001), vitality (p < 0.001), social functioning (p < 0.001), role emotional (p = 0.002), mental health (p < 0.001) and health transition (p < 0.001). For CD-RISC scores, the mean value of the control group was 42.03 ± 4.42 at baseline and increased to 50.36 ± 4.70 after 3 months (p < 0.001), while the intervention group was 40.00 ± 6.61 at baseline and increased to 65.12 ± 5.21 after 3 months (p < 0.001). Moreover, the CD-RISC score in the intervention group was significantly higher than that in the control group after 3 months (p < 0.001).

Conclusion

The application of an online multimodal nursing program could significantly improve the health-related quality of life and psychological resilience of asymptomatic PICC-RT patients. These findings provide evidence to support the necessity of an online multimodal nursing program in routine long-term follow-up, especially in the era of COVID-19.

A clinical study of peripherally inserted central catheter-related venous thromboembolism in patients with hematological malignancies

This study aimed to explore the risk factors of peripherally inserted central catheter (PICC)-related venous thromboembolism (CRT) in patients with hematological malignancies and the predictive ability of the thrombotic risk assessment models (RAMs). The clinical data of the 117 eligible patients with hematological neoplasms at Mianyang Central Hospital with PICC from May 2018 to May 2020 were analyzed in this retrospective study. Thrombosis risk scores were calculated in patients with image-confirmed PICC-related thromboembolism. CRT occurred in 19 cases. Compared to the CRT-free group, the CRT group was older and showed higher body mass index (BMI), leukocyte count level, and the prevalence of diabetes mellitus. Multivariable logistic regression analysis showed that BMI (P = 0.03) was a significant risk factor for CRT. The area under the receiver operating characteristic curve for the Caprini scale (P = 0.01) was higher than that of the modified Wells scale (P = 0.94), the revised Geneva scale (P = 0.83), Padua scale (P = 0.59), and Michigan scale (P = 0.80). The sensitivity and specificity for the Caprini scale, Padua scale, modified Wells scale, the revised Geneva scale, and Michigan risk score were 63.3%/73.7%, 100%/0.00%, 95.9%/5.3%, 31.6%/73.7%, and 1.0%/99.0%, respectively. Caprini RAM had a better predictive ability for CRT in patients with hematological malignancies. Michigan risk score may not be better than Caprini RAM in this population.

Autologous Hematopoietic Stem Cell Transplantation for Multiple Sclerosis, the Ottawa Protocol

Autologous hematopoietic stem cell transplantation (aHSCT) is increasingly used to treat patients with highly active multiple sclerosis (MS) refractory to disease-modifying therapy. Briefly, cyclophosphamide and filgrastim are used to mobilize autologous hematopoietic stem cells (HSC) into the circulation. HSC are harvested by leukapheresis, purified using a CD34 immunomagnetic selection process, and cryopreserved. Busulphan, cyclophosphamide, and rabbit anti-thymocyte globulin are used to destroy the patient's autoreactive immune system, followed by infusion of the previously collected HSC, which reconstitute a naïve and self-tolerant immune system. Many MS patients experience durable remissions with no evidence of new disease activity following aHSCT. Treatment-related toxicity is rare, but potentially life-threatening complications necessitate appropriate patient selection by MS neurologists and HSCT physicians. AHSCT must be performed with a highly trained multidisciplinary team expert to minimize morbidity and mortality. We present the current aHSCT procedure for an MS indication at The Ottawa Hospital, developed from our program's 20-year experience. © 2022 Wiley Periodicals LLC. Basic Protocol 1: Candidate selection Basic Protocol 2: Autologous hematopoietic stem cell mobilization, collection, purification, and cryopreservation Basic Protocol 3: Autologous hematopoietic stem cell transplantation Basic Protocol 4: Supportive care following recovery from aHSCT (Beyond 100 days) Basic Protocol 5: Ongoing evaluation of multiple sclerosis.

Conditional catheter-related thrombosis free probability and risk-adapted choices of catheter for lung cancer

Background

Current predictive tools assess catheter‐related thrombosis (CRT) in patients with lung cancer in a static manner at a single time point of catheterization. The subsequent hazard changes over time are unknown. The conditional catheter‐related thrombosis‐free probability (CCFP) can provide dynamic information on continual CRT‐free expectations. This study aimed to assess the CCFP and hazard rates based on risk categories and various venous access devices (VADs).

Methods

This retrospective study reviewed 939 patients with lung cancer with peripherally inserted central venous catheters (PICCs) or central venous catheters (CVCs) identified at the National Clinical Research Center for Cancer between January 1, 2015 and December 31, 2018. The incidence of CRT has also been reported. Patients were stratified into low‐ and high‐risk groups according to multivariate Cox regression analyses. CCFP is defined as the CRT‐free probability given that patients have no CRT for a definite time.

Results

A total of 507 patients with PICCs and 432 patients with CVCs were included in this study. The 3‐month CCFP increased from 74.2% at catheter insertion to 93.6% at 3 months. The hazards of CRT in the first month were highest (16.4%) and slightly thereafter. The high‐risk group initially had a higher (21.4%) but significantly decreased CRT hazard after 2 months (8.3%), whereas the low‐risk group maintained a comparable lower risk hazard of less than 5% after 1 month. In the overall cohort, patients with CVCs had lower CRT probability than those with PICCs (HR, 1.76; 95% CI: 1.28–2.41; p < 0.01). Further analysis demonstrated that compared with PICCs, CVCs provided a CRT‐free benefit in low‐risk patients (p = 0.02) but not in high‐risk patients (p = 0.06).

Conclusions

CCFP increased, and the hazards of CRT decreased over time in a risk‐dependent manner in patients with lung cancer. These valuable dynamic data may help optimize risk‐adjusted choices of VADs and risk‐adjusted prophylactic anticoagulation strategies for patients.

Nursing Effect and Prognosis Analysis of Self-Management Education Model Based on Protective Motivation Theory on Patients with Hematological Tumor after PICC Catheterization

Objective

To analyze the nursing effect and prognostic value of self-management education model based on protective motivation theory on patients with hematological malignancies (HM) after peripheral venous catheterization (PICC).

Methods

A total of 90 patients with HMs treated with PICC catheterization in our hospital from October 2019 to October 2021 were included in the study. The patients were randomly assigned into experimental group (n = 45) and control group (n = 45). On the basis of the control group, the experimental group implemented the self-management education model based on the theory of protective motivation, and the control group implemented routine nursing health education measures. The self-nursing ability scale (ESCA), Hamilton anxiety scale (HAMA), the average cost of PICC catheter maintenance, the incidence of PICC-related complications, and the score of Newcastle nursing satisfaction scale (NSNS) were observed 1 month before and after nursing.

Results

After one month of nursing, there was no significant difference in ESCA self-concept (p > 0.05). After one month of nursing, the scores of self-care responsibility, self-nursing skills, and health knowledge in the experimental group were significantly higher compared to those before nursing (p < 0.05) and higher compared to those in the control group (p < 0.05). After one month of nursing, the score of HAMA scale was significantly lower compared to that before nursing (p < 0.05), and the score of HAMA scale in the experimental group was lower compared to the control group (p < 0.05). After one month of nursing, the average cost of PICC pipeline maintenance in the test group was lower than that in the control group (p < 0.05). One month after nursing, the incidence of PICC-related complications in the experimental group was lower than that in the control group (p < 0.05). One month after nursing, the score of NSNS scale was significantly higher than that before nursing (p < 0.05). After one month of nursing, the score of NSNS scale in the experimental group was higher than that in the control group.

Conclusion

The self-management education model based on protective motivation theory is effective in nursing patients with peripheral venous catheterization and PICC catheterization of HMs. It is more beneficial to promote patients' self-nursing management ability, reduce anxiety, reduce the average cost of PICC pipeline maintenance, reduce the incidence of PICC-related complications, and enhance nursing satisfaction.

Metronomic chemotherapy regimens and targeted therapies in non-Hodgkin lymphoma: The best of two worlds

Novel drugs are rapidly moving forward the treatment-paradigm of non-Hodgkin-lymphomas (NHLs). Notwithstanding, especially in aggressive subtypes, chemotherapy remains the pillar of treatment. Indeed, the combination of highly effective Maximum-Tolerated-Dose Chemotherapy (MTD-CHEMO) + "novel drugs", has so far, fallen short from expectations, often because it caused excessive toxicity. Metronomic chemotherapy (mCHEMO), which is the frequent, long-term administration of low dose cytotoxic drugs, may allow more effective and tolerable combinations. mCHEMO pharmacodynamics, has been described as pleiotropic. In fact, it may have different cellular and molecular targets, when drugs or their schedules are modified. Although mCHEMO has been little explored in NHLs, pre-clinical studies - in lymphoma models - which addressed the activity of mCHEMO in combination with novel drugs, have shown very promising results. These included inhibitors of histone deacetylase, mTOR and PI3K/mTOR, as well as the immune checkpoint inhibitor anti-PD-L1. Moreover, a few impressive reports have recently shown all-oral mCHEMO schedules, with or without rituximab, can effectively shrink both B and T-cell aggressive NHLs. Indeed, these regimens allowed elderly-frail patients to achieve sustained remission, while toxicity proved manageable. In our opinion, all-oral mCHEMO, is an active, easy-to start, well-tolerated, and inexpensive therapeutic approach, which deserves further investigation. Most importantly, mCHEMO, holds promise to empower the activity of novel targeted therapies, without causing excessive toxicity.

Complications of peripherally inserted central catheters in adult hospitalized patients and outpatients in the KTFIXPICC study: A randomized controlled trial evaluating a fixation device KT FIX Plussystem

BACKGROUND

Poor securement potentiates Peripherally inserted central catheters (PICC) complications. A dressing device (KT FIX Plus) offers stronger skin attachment, which may reduce the risk of dressing disruption. We aimed to evaluate this device.

METHODS

We conducted a single-center parallel-group open-label randomized controlled trial. Hospitalized and outpatient consecutive adults requiring PICCs were randomized to KT FIX Plus or standard of care (SOC). The primary endpoint was the composite of PICC-associated complications until removal, including occlusion, migration, accidental withdrawal, infection, thrombosis, and hematoma.

RESULTS

No statistically significant difference was observed in terms of complications: 67 (35%) in the KT FIX Plus group vs 36 (37%) in the SOC group (log-rank P = 0.76). In multivariate Cox analysis, independent risk factors for PICC-associated complications were obesity (adjusted hazard ratio (aHR), 1.08, P < .001) and diabetes (aHR, 1.85, P = .039), adjusting for chronic renal failure, number of lumens, catheter/vein diameter ratio and duration of home-based care. Multiple lumen catheters increased the risk of accidental withdrawal and migration (HR, 2.4, P = .008).

CONCLUSIONS

In our study, the use of KT FIX Plus did not reduce the risk of complications adjusting for other risk factors such as obesity and diabetes. The number of catheter lumens is one of the modifiable factors to reduce complications. Further studies are required to find the best securement and dressing system.

Application of intracavitary electrocardiogram classification in peripherally inserted central catheter localization in cancer patients

OBJECTIVE

This study aimed to analyze the application value of intracavitary electrocardiogram (ECG) classification in peripherally inserted central catheter (PICC) tip localization in patients with cancer.

METHODS

Using a self-control study method, 325 patients with cancer underwent intracavitary ECGs to position the tip of a PICC catheter. The P wave, QRS wave amplitude, and waveform changes of each intracavitary ECG were recorded. Chest X-ray examination was performed after the catheterization to compare the results of different intracavity ECG maps with the results of the chest X-ray.

RESULTS

The intracavitary ECG positioning maps of the 325 patients were divided into four categories: (1) increased P wave (293 cases), accounting for 90.15% (293/325) of all cases; compared with the positioning results of the chest X-rays, the placement rate was 98.98% (290/293); (2) negative deepening of the P wave (1 case), accounting for 0.31% (1/325) of all cases and with a placement rate of 100% (1/1); (3) no change in P wave (19 cases), accounting for 5.85% (19/325) of all cases and with a placement rate of 42.11% (8/19); (4) atrial fibrillation/atrial flutter (12 cases), accounting for 3.69% (12/325) of all cases and with a placement rate of 58.33% (7/12). The four types of intracavitary ECG positioning maps had statistically significant differences (χ² = 133.924, P = 0.000).

CONCLUSION

There are four types of intracavitary ECG localization maps: increased P wave, negative deepening of the P wave, no change in P wave, and atrial fibrillation/atrial flutter. The increased P wave pattern had the highest occurrence probability and high positioning accuracy. It therefore has strong clinical application value for PICC tip localization in patients with cancer.

Dual-lumen power injectable peripherally inserted central catheters in allogeneic hematopoietic stem cell transplantation: A prospective observational study

AIMS AND OBJECTIVES

To explore whether dual-lumen power injectable peripherally inserted central catheters (PICCs) could be effectively and safely applied in allogeneic hematopoietic stem cell transplantation (allo-HSCT) and for serum cyclosporine level monitoring.

BACKGROUND

Compared to conventional central venous access devices, PICC provides a feasible route not only for fluid infusion, but also for blood sample collection in patients undergoing oncological treatments.

DESIGN

A prospective observational study was conducted according to the STROBE guidelines.

METHODS

We prospectively evaluated the applications and complications of power injectable PICCs in 52 consecutive allo-HSCT recipients. We also compared the cyclosporine levels in 188 paired blood samples, simultaneously obtained via power injectable PICCs and percutaneous venous puncture, to investigate whether power injectable PICC is a feasible route for cyclosporine concentration monitoring in allo-HSCT.

RESULTS

The median PICC placement duration was 29 days. The insertion-site blood oozing and central line-associated bloodstream infection rates were 36.5% (19/52) and 26.9% (14/52), respectively, indicating the feasibility of these PICCs for various applications in allo-HSCT. No power injectable PICC-related thrombotic adverse events were identified; 90.4% (47/52) of cases with power injectable PICC removal occurred because of lack of medical utility, suggesting that power injectable PICC-related complications were manageable. However, cyclosporine levels in samples obtained via these PICCs were significantly higher than those in samples obtained via percutaneous venous puncture (261.5 ± 139.2 vs. 232.4 ± 253.6 ng/ml; p = 0.019 [set 1]; 254.8 ± 89.3 vs. 225.1 ± 233.3 ng/ml; p<0.001 [set 2]; 283.6 ± 103.9 vs. 238.0 ± 254.7 ng/ml; p = 0.006 [set 3]; 291.0 ± 94.9 vs. 266.0 ± 274.7 ng/ml; p = 0.016 [set 4]).

CONCLUSION

The power injectable PICC is a feasible venous access device for allo-HSCT.

RELEVANCE TO CLINICAL PRACTICE

The dual-lumen power injectable PICCs provided a reliable access for blood sample collection, decreasing the number of blind percutaneous venous punctures in allo-HSCT. However, its application in cyclosporine level monitoring needs further investigation.

Catheter-related bloodstream infection associated with multiple insertions of the peripherally inserted central catheter in patients with hematological disorders

Patients with hematological disorders are treated with multiple cycles of chemotherapy. As a result, they often require multiple insertions of the peripherally inserted central catheter (PICC) for prolonged periods of time. Although PICCs have been widely used worldwide in various patients, the safety and feasibility of the multiple insertions of the PICC in this population have not been fully verified. We performed a retrospective analysis to clarify the relationship between complications and multiple PICC insertions in patients with hematological disorders who were treated with either chemotherapy or immunotherapy. A total of 651 PICCs were inserted in 261 patients with a median age of 66 years. Acute myeloid leukemia (AML) and non-Hodgkin's lymphoma were the most common diseases in our patient cohort. The total catheter days (CDs) was 29,485 days, with a median catheter duration of 30 days. The rate of catheter-related bloodstream infection (CRBSI) in our patient cohort at high rate of re-insertion was 2.0/1000 CDs. Although multiple PICC insertions were not a risk factor of CRBSI, our findings suggest that a prolonged catheter dwell time may be associated with CRBSI. AML was an important risk factor of CRBSI. While the PICC dwell time depends on the treatment cycle, our findings indicate that it should be limited to approximately 30 days and catheters may be removed and re-inserted as needed.

The incidence of asymptomatic thrombosis related to peripherally inserted central catheter in adults: A systematic review and meta-analysis People's

Aim

To examine the incidence and risk factors for asymptomatic peripherally inserted central catheter‐related thrombosis (PICC‐RT).

Design

We performed a systematic review and meta‐analysis following the PRISMA guidelines.

Methods

The review was registered in PROSPERO (CRD42020186732). A systematic search of EMBASE, CINAHL, PubMed, Web of Science and Cochrane was performed from inception to 4 June 2020. Meta‐analysis was performed to determine the pooled incidence of asymptomatic PICC‐RT.

Results

Ten studies comprising 1591 participants with 1592 PICCs were included in this meta‐analysis. The pooled incidence of asymptomatic PICC‐RT in adults was 22% (95% CI, 0.17–0.29). The pooled incidence of PICC‐RT in cancer patients was 19% (95% CI, 0.13–0.26). Asymptomatic PICC‐RT mainly occurred in superficial veins. Most asymptomatic thrombosis occurred 3–12 days after the PICC insertion. A higher Eastern Cooperative Oncology Group score (ECOG), slower blood flow velocity and left basilic vein were independent risk factors of asymptomatic thrombosis.

Outcomes of bedside peripherally inserted central catheter placement: a retrospective study at a single institution

BACKGROUND

Bedside insertion of peripherally inserted central catheters (PICCs) has higher rates of malposition than fluoroscopic-guided PICC placement. This study evaluated the success rate of bedside PICC placement, variations in tip location, and risk factors for malposition.

METHODS

This retrospective study included patients who underwent bedside PICC placement from January 2013 to September 2014 in a single institution. The procedure was conducted under ultrasound guidance or by a blind method. After PICC placement, tip location was determined by chest X-ray.

RESULTS

The overall venous access success rate with bedside PICC placement was 98.1% (1,302/ 1,327). There was no significant difference in the venous access success rate between ultrasound-guided placement (868/880, 98.6%) and a blind approach placement (434/447, 97.1%). Optimal tip position was achieved on the first attempt in 1,192 cases (91.6%). Repositioning was attempted in 65 patients; 60 PICCs were repositioned at the bedside, two PICCs were repositioned under fluoroscopic guidance, and three PICCs moved to the desired position without intervention. Final optimal tip position after repositioning was achieved in 1,229 (94.4%). In logistic regression analysis, five factors associated with tip malposition included female sex (Exp(B), 1.687; 95% confidence interval [CI], 1.180 to 2.412; P=0.004), older age (Exp(B), 1.026; 95% CI, 1.012 to 1.039; P<0.001), cancer (Exp(B), 0.650; 95% CI, 0.455 to 0.929; P=0.018), lung disease (Exp(B), 2.416; 95% CI, 1.592 to 3.666; P<0.001), and previous catheter insertions (Exp(B), 1.262; 95% CI, 1.126 to 1.414; P<0.001).

CONCLUSIONS

Bedside PICC placement without fluoroscopy is effective and safe in central venous catheters. Potential risk factors associated with catheter tip malposition include older age, female sex, cancer, pulmonary disease, and previous central vein catheterizations.
