Risk factors associated with catheter-related upper extremity deep vein thrombosis in patients with peripherally inserted central venous catheters: a prospective observational cohort study: part 2

Establishment of risk nomogram prediction model for venous catheter thrombosis

BACKGROUND

Venous catheters are widely used in clinical practice, but a drawback of their usage is the increased risk of thrombosis.

AIMS

The current study explored the risk factors affecting the formation of thrombosis following venous catheterization and establishes a risk nomogram prediction model for catheter-related thrombosis.

METHODS

Univariate and multivariate logistic regression analyses were carried out to identify the independent factors involved in venous catheter thrombosis. These factors were included in the construction of a nomogram. Finally, the C-index and calibration curves were used to validate the nomogram.

RESULT

A total of 146 cases were included in the sample, of which 36 were cases of thrombosis. The results of the univariate logistic regression analysis showed that the following were significant factors: age, Acute Physiology and Chronic Health Evaluation scoring system (APACHE II) score, white blood cell (WBC), hematocrit (HCT), international normalized ratio (INR), fibrinogen (FIB), and D-dimer. Multivariate logistic regression analysis was performed, which confirmed that the factors of age (AUC: 0.677, 95% CI: 0.564-0.790), APACHE II score (AUC: 0.746, 95% CI: 0.656-0.837), INR (AUC: 0.743, 95% CI: 0.636-0.849), and D-dimer (AUC: 0.826, 95% CI: 0.750-0.902) were independent variables. Next, a nomogram was constructed using these independent variables for predicting venous catheter thrombosis. Favorable results with C-indexes (0.816; 95% CI: 0.780-0.882) and calibration curves closer to ideal curves indicated the accurate predictive ability of this nomogram.

CONCLUSION

The individualized nomogram demonstrated effective prognostic prediction for patients with venous thrombosis.

The incidence and risk of venous thromboembolism associated with peripherally inserted central venous catheters in hospitalized patients: A systematic review and meta-analysis

Background

Venous thromboembolism (VTE) can be fatal if not treated promptly, and individual studies have reported wide variability in rates of VTE associated with peripherally inserted central catheters (PICC). We thus conducted this meta-analysis to investigate the overall incidence and risk of developing PICC-related VTE in hospitalized patients.

Methods

We searched PubMed, Embase, Scopus, and Web of Science databases from inception until January 26, 2022. In studies with a non-comparison arm, the pooled incidence of PICC-related VTE was calculated. The pooled odds ratio (OR) was calculated to assess the risk of VTE in the studies that compared PICC to the central venous catheter (CVC). The Newcastle-Ottawa Scale was used to assess methodological quality.

Results

A total of 75 articles (58 without a comparison arm and 17 with), including 109292 patients, were included in the meta-analysis. The overall pooled incidence of symptomatic VTE was 3.7% (95% CI: 3.1–4.4) in non-comparative studies. In the subgroup meta-analysis, the incidence of VTE was highest in patients who were in a critical care setting (10.6%; 95% CI: 5.0–17.7). Meta-analysis of comparative studies revealed that PICC was associated with a statistically significant increase in the odds of VTE events compared with CVC (OR, 2.48; 95% CI, 1.83–3.37; P < 0.01). However, in subgroup analysis stratified by the study design, there was no significant difference in VTE events between the PICC and CVC in randomized controlled trials (OR, 2.28; 95% CI, 0.77–6.74; P = 0.13).

Conclusion

Best practice standards such as PICC tip verification and VTE prophylaxis can help reduce the incidence and risk of PICC-related VTE. The risk-benefit of inserting PICC should be carefully weighed, especially in critically ill patients. Cautious interpretation of our results is important owing to substantial heterogeneity among the studies included in this study.

Central venous catheter-related thrombosis in pediatric surgical patients: A prospective observational study

BACKGROUND

Perioperative central venous catheters are required but may be associated with various complications.

AIMS

The purpose of our study was to assess the incidence and perioperative risk factors for catheter-related internal jugular vein thrombosis in pediatric surgical patients.

METHODS

This prospective observational study included children under 6 years of age who were scheduled to undergo central venous catheterization of the right internal jugular vein under general anesthesia. A central venous catheter was inserted under real-time ultrasound guidance. An investigator examined for thrombosis using ultrasonography at predetermined time points. The primary aim was the incidence of catheter-related thrombosis from insertion until the 5th day postoperatively or the removal of the central venous catheter. The secondary aim was the determination of the risk factors for thrombosis.

RESULTS

Eighty patients completed the study. Internal jugular vein thrombi were found in 31 patients (38.8%, 95% CI 28.0-49.4). On multiple logistic regression analyses, the number of insertion attempts was the only influencing factor for catheter-related thrombosis (p < .001). More than two insertion attempts increased the risk of thrombosis (odds ratio 5.6; 95% CI 1.7 - 18.7, p = .004). Anesthesia time (p = .017; mean difference 166.4 min; 95% CI 55.7-277.1), intraoperative red blood cell transfusion (p = .001; median difference 21.1 ml kg^-1 ; 95% CI 6.6-34.4), and intensive care unit stay (p = .001; median difference 100.0 h; 95% CI 48-311) differed between patients with transient thrombosis and those with thrombosis lasting for more than 3 days.

CONCLUSION

Internal jugular vein thrombosis was frequently detected by ultrasound following central venous catheterization in pediatric surgical patients. Multiple insertion attempts may be associated with the incidence of thrombosis. The clinical relevance of thrombi detected via ultrasound surveillance has not been determined.

Risk Factors for Catheter-Related Thrombosis in Multiple Myeloma Patients Undergoing Autologous Stem Cell Transplantation

Background and Objectives: Cancer associated thrombosis (CAT) is a common complication of neoplasms. Multiple myeloma (MM) carries one of the highest risks of CAT, especially in the early phases of treatment. Autologous stem cell transplantation (ASCT) as the standard of care in transplant-eligible patients with MM carries a risk of catheter-related thrombosis (CRT). The aim of this study was identification of the risk factors of CRT in MM patients undergoing ASCT in 2009–2019. Materials and Methods: We retrospectively analyzed patients with MM undergoing ASCT. Each patient had central venous catheter (CVC) insertion before the procedure. The clinical symptoms of CRT (edema, redness, pain in the CVC insertion area) were confirmed with Doppler ultrasound examination. We examined the impacts of four groups of factors on CRT development: (1) patient-related: age, gender, Body Mass Index (BMI), obesity, Charlson comorbidity index, hematopoietic stem cell transplantation comorbidity index, renal insufficiency, and previous thrombotic history; (2) disease-related: monoclonal protein type, stage of the disease according to Salmon–Durie and International Staging System, number of prior therapy lines, and MM response before ASCT; (3) treatment-related: melphalan dose, transplant-related complications, and duration of post-ASCT neutropenia; (4) CVC-related: location, time from placement to removal. Results: Symptomatic CRT was present in 2.5% (7/276) of patients. Univariate analysis showed an increased risk of CRT in patients with a catheter-related infection (OR 2.4, 95% CI; 1.109–5.19, p = 0.026), previous thrombotic episode (OR 2.49, 95% CI; 1.15–5.39, p = 0.021), previous thrombotic episode on initial myeloma treatment (OR 2.75, 95% CI; 1.15–6.53, p = 0.022), and gastrointestinal complications of ASCT such as vomiting and diarrhea (OR 3.87, 95% CI; 1.57–9.53, p = 0.003). In multivariate analysis, noninfectious complications were associated with higher CRT incidence (OR 2.75, 95% CI; 1.10–6.19, p = 0.031). Conclusions: The incidence of symptomatic CRT in ASCT in MM was relatively low. Previous thrombotic events, especially during the induction of myeloma treatment, increased CRT risk during ASCT. Dehydration following gastrointestinal complications may predispose to higher CRT incidence.

Risk factors for peripherally inserted central catheter line-related deep venous thrombosis in critically ill intensive care unit patients

Introduction:

Central venous access using peripherally inserted central catheters is frequently used for patients receiving intravenous medications in the hospital or outpatients. Although there are several benefits of peripherally inserted central catheters, such as ease of insertion, low procedure-related risk and higher patient satisfaction, there are complications associated with peripherally inserted central catheter use. Despite some studies evaluating peripherally inserted central catheter line–related complications, the factors associated with peripherally inserted central catheter–related deep venous thrombosis in critically ill medical-surgical patients are poorly described. The objective of this case-control study was to identify the risk factors associated with peripherally inserted central catheter line–related deep venous thrombosis in critically ill medical-surgical intensive care unit patients in a community hospital.

Methods:

We abstracted relevant clinical data from 21 cases with symptomatic peripherally inserted central catheter–related deep venous thrombosis and 42 controls with peripherally inserted central catheters but no deep venous thrombosis.

Results:

Of the factors evaluated, female gender, the use of triple lumen peripherally inserted central catheters, larger outer diameter, and open (vs valve) peripherally inserted central catheters were associated with venous thrombosis. In this retrospective study, we did not identify any association of peripherally inserted central catheter–related deep venous thrombosis with a prior history of deep venous thrombosis, use of alteplase, antiplatelet therapy, prophylactic or therapeutic anticoagulation, international normalized ratio, platelet count and the use of peripherally inserted central catheters for total parenteral nutrition.

Conclusion:

Our study indicates that the catheter size relative to the diameter of the vein could be an important risk factor for the development of peripherally inserted central catheter–related deep venous thrombosis. The study findings should be confirmed in a larger study designed to identify risk factors of peripherally inserted central catheter–related deep venous thrombosis. In the meantime, the peripherally inserted central catheter lines should be used judiciously in critically ill patients.

Randomized Clinical Trial Evaluating Complications and Complication-Related Removal of Arm-Situated Power-Injectable and Non-Power-Injectable Totally Implanted Venous Access Devices among Cancer Patients

PURPOSE

To evaluate the hypothesis that power-injectable (PI) totally implanted venous access devices (TIVADs) situated in the arm are associated with more frequent complications and complication-related removal than non-power-injectable (NPI) arm TIVADs among adult cancer patients.

MATERIALS AND METHODS

In this single-center trial, 211 adult chemotherapy patients were randomized to receive either a PI or a NPI arm TIVAD. Follow-up involved a standardized telephone interview 1 week after insertion, followed by a chest X-ray, arm X-ray, and Doppler ultrasound at 3 months and 12 months. Online complication reporting was also provided by patients and care providers for a minimum of 1 year. The primary end point was removal for port-related complications; the secondary end point was the occurrence of any port-related complication.

RESULTS

Forty-two complications occurred (19.9% of patients), precipitating the removal of 6 PI ports and 7 standard ports. Time-to-removal did not differ between TIVAD types (hazard ratio 0.75, 95% confidence interval [CI] 0.25-2.24; P = .61). Complications were related to thrombosis, infection, or mechanical issues, with no statistical difference between groups for overall occurrence (23.1% vs 17.0%, odds ratio 1.47, 95% CI 0.74-2.92; P = .27); however, by type of complication, thrombosis occurred more frequently among PI TIVAD patients (15.2% vs 6.1%, odds ratio 2.79, 95% CI 1.04-7.44; P = .03).

CONCLUSIONS

There was no difference in port-related complication occurrence or complication-related removal when using the arm PI port compared with the NPI port among cancer patients.

When Is Parenteral Nutrition Appropriate?

Parenteral nutrition (PN) represents one of the most notable achievements of modern medicine, serving as a therapeutic modality for all age groups across the healthcare continuum. PN offers a life-sustaining option when intestinal failure prevents adequate oral or enteral nutrition. However, providing nutrients by vein is an expensive form of nutrition support, and serious adverse events can occur. In an effort to provide clinical guidance regarding PN therapy, the Board of Directors of the American Society for Parenteral and Enteral Nutrition (ASPEN) convened a task force to develop consensus recommendations regarding appropriate PN use. The recommendations contained in this document aim to delineate appropriate PN use and promote clinical benefits while minimizing the risks associated with the therapy. These consensus recommendations build on previous ASPEN clinical guidelines and consensus recommendations for PN safety. They are intended to guide evidence-based decisions regarding appropriate PN use for organizations and individual professionals, including physicians, nurses, dietitians, pharmacists, and other clinicians involved in providing PN. They not only support decisions related to initiating and managing PN but also serve as a guide for developing quality monitoring tools for PN and for identifying areas for further research. Finally, the recommendations contained within the document are also designed to inform decisions made by additional stakeholders, such as policy makers and third-party payers, by providing current perspectives regarding the use of PN in a variety of healthcare settings.

Assessment of thrombosis in right internal jugular vein after percutaneous superior vena cava catheter insertion during cardiovascular surgery with cardiopulmonary bypass

OBJECTIVE

We evaluated the incidence of percutaneous superior vena cava catheter-related thrombosis and identified risk factors for developing the condition in patients undergoing cardiovascular surgery with cardiopulmonary bypass.

METHODS

A total of 121 patients were evaluated. A percutaneous superior vena cava catheter was inserted into the right internal jugular vein during cardiovascular surgery with cardiopulmonary bypass. The right internal jugular vein was evaluated using ultrasonography, including cross-sectional area and velocity just before insertion of the percutaneous superior vena cava catheter (preoperative) and 24 hours and 48 hours after its insertion. If an echogenic mass was detected in the right internal jugular vein, the size was measured.

RESULTS

The incidence of thrombosis in the right internal jugular vein was 56.2%. Change in the right internal jugular vein cross-sectional area and velocity had no clinical implications. Multiple logistic regression analysis identified age (odds ratio, 1.061; 95% confidence interval, 1.022-1.101; P = .002), superior vena cava catheter indwelling duration (odds ratio, 1.015; 95% confidence interval, 1.008-1.023; P < .001), and amount of transfusion platelet concentrate (odds ratio, 1.155; 95% confidence interval, 1.030-1.295; P = .013) as risk factors for percutaneous superior vena cava catheter-related thrombosis in the right internal jugular vein.

CONCLUSIONS

The incidence of percutaneous superior vena cava catheter-related thrombosis was higher than conventional central venous catheter-related thrombosis. Risk factors were age, superior vena cava catheter indwelling duration, and amount of transfusion platelet concentrate.

A systematic review of patient-related risk factors for catheter-related thrombosis

To identify patient-related risk factors for venous thrombosis in patients with central venous catheters (CVC) or peripherally inserted central catheters (PICC). We performed a systematic review of the literature assessing patient-related risk factors for thrombosis related to CVC or PICC. The databases PubMed, Ovid and the Cochrane library were searched for observational studies pertaining to patient-related risk factors for CVC and PICC-related thrombosis. The initial search through PubMed, Ovid and the Cochrane library yielded 516 results. After 71 duplicates were removed, 445 articles were assessed for eligibility based on title and abstract. Four hundred and eleven articles were then excluded and 33 full text articles were manually assessed for eligibility. Eight articles were eliminated as they did not contain content relevant to the review. Twenty-five studies were then selected to assess 20 risk factors. There were no consistent significant associations for catheter-related thrombosis across the twenty-five studies. Multiple studies identified age, malignancy, diabetes, obesity, chemotherapy, thrombophilia and a history of thrombosis as significant risk factors for catheter-related thrombosis. Inconsistent findings among studies make it difficult to establish which patient-related risk factors are associated with catheter-related thrombosis. Future studies could include larger sample sizes and more cases of catheter-related thrombosis to produce more significant results. Identification of patient-related risk factors could lead to early recognition of upper limb deep vein thrombosis in patients with catheters, thereby preventing complications.

In-Hospital Management and Follow-Up Treatment of Venous Thromboembolism: Focus on New and Emerging Treatments

Venous thromboembolism (VTE), encompassing pulmonary embolism (PE) and deep venous thrombosis (DVT), is a major cause of morbidity and mortality of particular relevance for intensivists and hospitalists. Acute VTE is usually managed with parenteral unfractionated heparin or low-molecular-weight heparin, followed by an oral vitamin K antagonist. Data are lacking for optimal treatment of less common occurrences, such as upper extremity DVT, and for approaches such as thrombolysis for PE associated with early signs of hemodynamic compromise or inferior vena cava filters when anticoagulation is contraindicated. Direct oral anticoagulants (DOACs) including apixaban, dabigatran, edoxaban, and rivaroxaban are now added to the armamentarium of agents available for acute management of VTE and/or reducing the risk of recurrence. This review outlines an algorithmic approach to acute VTE treatment: from aggressive therapies when anticoagulation may be inadequate, to alternative choices when anticoagulation is contraindicated, to anticoagulant options in the majority of patients in whom anticoagulation is appropriate. Evidence-based guidelines and the most recent DOAC clinical trial data are discussed in the context of the standard of care. Situations and treatment approaches for which data are unavailable or insufficient are identified. VTE therapy in care transitions is discussed, as are choices for secondary prevention.

Case Report: Inflammatory Bowel Disease and Thrombosis

Patients with inflammatory bowel disease (IBD) have a greater risk for developing venous thromboembolism (VTE). Patients admitted to the hospital with IBD flares often require insertion of long-term venous access devices, such as peripherally inserted central catheters (PICCs), to provide access for medications, blood draws, fluid management, and nutrition. PICCs have been associated with an increased risk for upper extremity deep vein thrombosis. In this case study analysis, 2 patients with IBD and PICCs who developed VTE are examined. The case report includes a thorough discussion of medical history, symptomology, PICC insertion, and events leading to VTE development. A review of acquired risk factors for IBD patients and a comparison of risk factors that predisposed each to VTE are explored. These cases highlight the need for nurses and physicians to heighten surveillance and engage in proactive strategies to prevent VTE in this population of patients.
