RESUMO

Chronic venous obstructions resulting from indwelling lines, surgery and instrumentation, and congenital anomalies are increasingly common in patients with congenital heart disease (CHD) and other chronic illnesses. Venous obstruction results in threatened long-term vascular access and congestive symptoms. Endovascular therapies are safe and can be effective at rehabilitating obstructed and even occluded veins. The risk of recurrent obstruction is high, however. Post-rehabilitation monitoring and anticoagulation therapy are important, and reinterventions are common. Here, the authors describe techniques to address a variety of venous obstruction lesions that may be encountered in CHD patients and provide illustrative cases.

RESUMO

To explore the clinical application value of intracavitary electrocardiogram (ECG) localization combined with ultrasound in central venous catheterization in critically ill patients. A total of 103 patients who were treated in the intensive care unit of our hospital from October 2020 to June 2023 were selected as the study subjects, and according to the differences in their central venous catheter placement methods, they were divided into study group (n = 52, receiving ultrasound combined with intracavitary ECG localization for catheterization) and control group (n = 51, receiving routine catheterization). The differences in the catheter placement accuracy, catheter depth, catheter placement duration, incidence of catheter-related complications, length of stay, and hospitalization expenses between the 2 groups were compared. The analysis utilizing X-ray for catheter tip positioning indicated that the catheter tip placement rate was higher in the study group than in the control group, and the catheter tip malposition rate was lower than in the control group (P < .05). There was no statistical significance in the catheter depth between study group and control group (P > .05), and the catheter placement duration of study group was significantly lower than that of control group, with statistical significance (P < .05). One case of partial catheter blockage, one case of catheter-related bloodstream infection, and one case of phlebitis were observed in study group, with an overall incidence of complications of 5.77% (3/52), which was significantly lower than 21.57% (11/51) of control group (P < .05). The length of stay and hospitalization expenses in study group were significantly lower than those in control group, with statistical significance (P < .05). The combined use of ultrasound and intracavitary ECG localization in critically ill patients undergoing central venous catheterization can help increase the success rate of catheter placement, shorten the catheter placement duration, reduce the incidence of various catheter-related complications, and also reduce the length of stay and hospitalization expenses.

RESUMO

Central venous catheter (CVC) placement is a challenging procedure with known iatrogenic risks. However, there are no residency program requirements to demonstrate baseline CVC procedural competency. Competency-based procedural education has been shown to decrease CVC-associated morbidity, but there has been limited literature about institution-wide efforts to ensure initial trainee competency for CVC placement. This study describes the implementation of a competency-based CVC curriculum for first-year interns across an institution before supervised clinical care. An institution-wide, simulation-based mastery training curriculum was designed to assess initial competency in CVC placement in first-year residents during 2021 and 2022. A checklist was internally developed with a multidisciplinary team. Using the Mastery-Angoff technique, minimum passing standards were derived to define competency levels considered appropriate for intern participation in supervised clinical care. Interns were trained through the competency-based program with faculty assessing intern performance using the CVC checklist to verify procedural competency. Over 2 academic cycles, 229 interns from 20 specialties/subspecialties participated. Overall, 83% of interns met performance standards on their first posttest attempt, 14% on the second attempt, and 3% on the third attempt. Interns from both cycles demonstrated significant improvement from baseline to posttest scores (P < .001). Overall, 10.5% of interns performed dangerous actions during assessment (malpositioning, retained guidewire, or carotid dilation). All interns ultimately achieved the passing standard to demonstrate initial competency in the simulation assessment. All participating interns demonstrated simulation-based competency allowing them to place CVCs under supervised clinical care. Dangerous actions, however, were not uncommon. Simulation-based teaching and learning frameworks were a feasible method to promote patient safety through an institutional-wide verification of preliminary procedural competency.

RESUMO

OBJECTIVES: Ethanol lock therapy (ELT) is a potential method of central catheter salvage following central line-associated bloodstream infection (CLABSI) although there is potential risk of catheter damage in polyurethane catheters. Further, there is limited efficacy data across the spectrum of common pediatric catheters, and published ELT protocols describe dwell times that are not feasible for critically ill children. We sought to evaluate the safety and efficacy of ELT in polyurethane catheters using brief (30 min to 2 hr) dwell times in our PICU. DESIGN: Investigational pilot study using historical control data. SETTING: PICU in quaternary care, free-standing children's hospital. INTERVENTIONS: ELT in polyurethane central venous catheters for catheter salvage. RESULTS: ELT with brief dwell times was used in 25 patients, 22 of whom were bacteremic. Ultimately 11 patients, comprising 14 catheters, were diagnosed with a primary CLABSI. The catheter salvage rate in primary CLABSI patients receiving ELT was 92% (13/14) and significantly higher than the salvage rate in patients receiving antibiotics alone (non-ELT) (62%, 39/64; mean difference 0.32, 95% CI [0.14-0.50], p = 0.03). The rate of catheter fracture in all patients receiving ELT was 8% (2/25) while the rate of fracture in the non-ELT group was 13% (8/64; mean difference -0.05, 95% CI [-0.18 to 0.09], p = 0.72). The rate of tissue plasminogen activator (tPA) use in the ELT group was 8% (2/25), whereas the rate of tPA use in the non-ELT group was significantly higher at 42% (26/64; mean difference -0.34, 95% CI [-0.49 to -0.17], p = 0.002). CONCLUSIONS: The use of ELT for catheter salvage and prophylaxis in the PICU is safe in a variety of polyurethane catheters. Dwell times ranging from 30 minutes to 2 hours were effective in sterilizing the catheters while allowing other therapies to continue. This approach may decrease the need for frequent line changes in a medically fragile pediatric population.

RESUMO

OBJECTIVE: Despite the effort to increase the proportion of patients starting dialysis on native accesses, many of them are still dialyzed on tunnelled catheter. Catheter-related complications are often serious and responsible for re-hospital admission, high morbidity and mortality. Several multicenter trials have reported results in the use of tunnelled dialysis catheter (TDC). However, few single-center studies have been published to verify the outcome from real-world experience. This study presents our center's experience in managing such patients in the context of relevant literature. METHODS: Demographics and operative data were retrospectively collected from medical charts. A prospective follow-up was performed to investigate complications, number of re-hospitalizations and mortality. Kaplan-Meier estimate was used to evaluate catheter primary patency and patients' overall survival. RESULTS: Among a total 298 haemodialysis accesses interventions, 105 patients (56 men, 53.3% and 49 women, 46.7%) with a median age of 65 years (range 32-88 years) were included in the study. All insertions were successful with an optimal blood flow achieved during the first session of dialysis in all cases. A catheter-related complication was detected in 33.3% (n=35) patients (48.6% infections; 28.6% TDC dysfunction; 14.3% local complications; 5.7% accidental catheter retractions; 2.8% catheter migrations). At a median follow-up of 10.5±8.5 months, a total of 85 patients (80.9%) was re-hospitalized, in 28 cases (26.7%) for a catheter-related cause. The median catheter patency rate was 122 days. At the last follow-up, 39 patients (37.1%) were still dialyzed on catheter, 30(28.6%) were dialyzed on an arteriovenous fistula and 7(6.7%) received a kidney transplantation. Two patients (2%) were transferred to peritoneal dialysis and two patients (2%) recover from renal insufficiency. Mortality rate was 23.8% (25 patients). Causes of death were myocardial infarction (n=13, 52%), sepsis (n=9, 36%); one patient (4%) died from pneumonia, one (4%) from uremic encephalopathy and one (4%) from massive hematemesis. CONCLUSION: TDCs may represent the only possible access in some patients, however they are burned with a high rate of complications, re-hospital admission and mortality. Results from this institutional experience are in line with previously published literature data in terms of morbidity and mortality. The present results reiterate once more that TDC must be regarded as a temporary solution while permanent access creation should be prioritized. Strict surveillance should be held in patients having TDC for the early identification of complications allowing the prompt treatment and modifying the catheter insertion site whenever needed.

RESUMO

Due to low compliance by bedside nursing with a central line-associated bloodstream infection (CLABSI) prevention bundle and increased CLABSI rates, a mandatory re-education initiative at a 1200-bed university-affiliated hospital was undertaken. Despite this, 2 units, housing high-risk immunocompromised patients, continued to experience increased CLABSI rates. A quality improvement before-after project design in these units replaced bedside nursing staff with 2 nurses from the vascular access team (VAT) to perform central vascular access device (CVAD) dressing changes routinely every 7 days or earlier if needed. The VAT consistently followed the bundled components, including use of chlorhexidine gluconate (CHG)-impregnated dressings on all patients unless an allergy was identified. In this case, a non-CHG transparent semipermeable membrane dressing was used. There were 884 patients with 14 211 CVAD days in the preimplementation period and 1136 patients with 14 225 CVAD days during the postimplementation period. The VAT saw 602 (53.0%) of the 1136 patients, performing at least 1 dressing change in 98% of the patients (n = 589). The combined CLABSI rate for the 2 units decreased from 2.53 per 1000 CVAD days preintervention to 1.62 per 1000 CVAD days postintervention. The estimated incidence rate ratio (IRR) for the intervention was 0.639, a 36.1% reduction in monthly CLABSI rates during the postimplementation period.

RESUMO

This study aimed to determine the practices of nurses working in pediatric and adult oncology clinics regarding totally implantable venous access device (TIVAD) care. The descriptive study was conducted with 227 oncology nurse members of the Oncology Nursing Association. The data were collected online with a survey form, which included questions about the participants' sociodemographic characteristics, professional experience, and TIVAD implementation practices. Descriptive statistics and ꭓ2 tests were used for the analysis of the data. It was determined that 44.1% of the nurses used 0.9% NaCl for active TIVAD flushing; 15.9% of them used a positive-pressure 0.9% NaCl-filled syringe; 12.3% used antireflux connectors; 85.5% used manual positive pressure technique; and 53.7% used the pulsatile technique. A statistical difference was found between nurses' training on TIVAD care and TIVAD occlusion rate in the clinic, TIVAD infection rate, following the guidelines, and using the pulsatile technique (P < .05). This study revealed that there are differences in the practices for TIVAD care and that the recommendations in the literature/guidelines are not implemented at the desired level to ensure continuity and prevent complications.

RESUMO

BACKGROUND: The position of the catheter tip of totally implantable venous access devices (TIVAD) is a risk factor for postoperative complications. The study aim was to assess the early and late complications (EC and LC) associated with the position of the catheter tip in cancer patients. METHODS: We reviewed cancer patients who had a TIVAD placed in 2020. EC (≤ 90 days), LC (> 90 days) and risk factors for TIVAD-associated complications were assessed. The vertical mismatch of the catheter tip was compared to an "ideal position" (> 10 mm below the carina and ≥ 20 mm below the right main bronchus (RMB)) using chest x-ray, post-implantation. RESULTS: 301 patients were included. Median follow-up after TIVAD implantation was 9.4 months. All TIVAD catheters were inserted via the internal jugular vein (IJV). The mean distance between the catheter tip and the carina and the RMB was 21.3 mm and 6.63 mm respectively. In total, 11.3% patients developed EC and 5.6% had LC. An association was found between the position of the catheter tip from the carina (≤ 10 mm vs. > 10 mm) and the occurrence of EC (18.3% vs. 8.6%, p = 0.01) and for the catheter insertion side (left IJV vs. right IJV) (19.1% vs. 9.0% p = 0.02). Multivariate analysis showed that left IJV catheter insertion (OR 2.76), and a catheter tip located ≤ 10 mm below the carina (OR 2.71) are significant independent risk factors of EC. CONCLUSIONS: TIVAD catheter tip located at ≤ 10 mm below the carina, and a left-side inserted catheter, are higher risk of EC.

RESUMO

OBJECTIVES: To compare catheter-related outcomes of individuals who received a tunnelled femorally inserted central catheter (tFICC) with those who received a peripherally inserted central catheter (PICC) in the upper extremities. DESIGN: A propensity-score matched cohort study. SETTING: A 980-bed tertiary referral hospital in South West Sydney, Australia. PARTICIPANTS: In-patients referred to the hospital central venous access service for the insertion of a central venous access device. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome of interest was the incidence of all-cause catheter failure. Secondary outcomes included the rates of catheters removed because of suspected or confirmed catheter-associated infection, catheter dwell and confirmed upper or lower extremity deep vein thrombosis (DVT). RESULTS: The overall rate of all-cause catheter failure in the matched tFICC and PICC cohort was 2.4/1000 catheter days (95% CI 1.1 to 4.4) and 3.0/1000 catheter days (95% CI 2.3 to 3.9), respectively, and when compared, no difference was observed (difference -0.63/1000 catheter days, 95% CI -2.32 to 1.06). We found no differences in catheter dwell (mean difference of 14.2 days, 95% CI -6.6 to 35.0, p=0.910); or in the cumulative probability of failure between the two groups within the first month of dwell (p=0.358). No significant differences were observed in the rate of catheters requiring removal for confirmed central line-associated bloodstream infection (difference 0.13/1000 catheter day, 95% CI -0.36 to 0.63, p=0.896). Similarly, no significant differences were found between the groups for confirmed catheter-related DVT (difference -0.11 per 1000 catheter days, 95% CI -0.26 to 0.04, p=1.00). CONCLUSION: There were no differences in catheter-related outcomes between the matched cohort of tFICC and PICC patients, suggesting that tFICCs are a possible alternative for vascular access when the veins of the upper extremities or thoracic region are not viable for catheterisation.

RESUMO

A woman in her 80s was admitted to the emergency department with an acute infective exacerbation of chronic obstructive pulmonary disease and type 2 respiratory failure, culminating in cardiac arrest for 2 min. She was successfully resuscitated, connected to a mechanical ventilator and subsequently transferred to the intensive care unit. Later in her hospital stay, the patient underwent a tracheostomy following prolonged intubation.During this period, she developed septic shock with complications, including acute kidney injury, metabolic acidosis and volume overload. As a result, the nephrologist recommended emergency haemodialysis. Initially, a left femoral haemodialysis catheter was established but had to be withdrawn a few days later due to the development of deep vein thrombosis (DVT). A left internal jugular catheter was then inserted but was removed after 5 days due to another DVT. It was subsequently replaced with a central line for vasopressor support.A Doppler scan revealed a large thrombus in the right internal jugular vein, extending to the area just above the superior vena cava. A similar thrombus was detected in the left internal jugular vein, with weak blood flow observed in both the right and left subclavian veins. Although the subclavian vein flows were deemed adequate, there was unsatisfactory blood flow through the catheter after insertion, rendering it unsuitable for haemodialysis.Due to an earlier central line-related infection, the right femoral site exhibited signs of infection and the presence of a pus pocket, making it unsuitable for haemodialysis access. To address this, the right popliteal vein was chosen for catheterisation using a 20-cm, 12 French catheter, the longest available catheter in the country at the time. The patient was placed in a prone position, and the catheter was smoothly inserted with ultrasound guidance, resulting in good flow. Subsequent haemodialysis sessions were carried out regularly.

RESUMO

There are many studies on central catheter related thrombosis (CCRT), however, there are significantly fewer studies focusing on the incidence and evolution of CCRT in the adult critical care population. This article reviews data collected from observational studies that have performed bedside duplex ultrasound for surveillance of CCRT and discuss if we should routinely screen for CCRT. The reported CCRT incidence is 17-38%, with most thrombus being detectable on ultrasound within seven days of line placement. Nearly all CCRT are designated as asymptomatic (no associated pulmonary embolism (PE) or deep vein thrombosis (DVT)) and no significant changes in mortality rates amongst patients that develop CCRT were reported. Based on the evidence reviewed, we do not recommend screening routinely for CCRT in the adult critical care population.

RESUMO

PURPOSE OF REVIEW: Securing safe and effective intravenous (IV) access is of utmost importance for administering parenteral nutrition (PN). Sustaining this access can indeed pose challenges, especially when dealing with the risk of complications associated with long-term PN. This review emphasizes best practices to optimize intravenous access and reviews the current evidence-based recommendations and consensus guidelines. RECENT FINDINGS: An individualized approach when selecting central venous catheters (CVC) is recommended, considering the estimated duration of need for IV access and the number of lumens needed. Established and novel approaches to minimize complications, including infection and thrombosis, are recognized. These include placement and positioning of the catheter tip under sonographic guidance and the use of antimicrobial lock therapies. Moreover, when possible, salvaging CVCs can reduce the risk of vascular access loss. CVC selection for patients requiring PN depends on several factors. Carefully reviewing an individual patient's clinical characteristics and discussing options is important. Given the increased infection risk, CVC lumens should be minimized. For long-term PN beyond 6 months, using CVCs with skin barriers and larger diameters should be considered.

RESUMO

BACKGROUND & AIMS: Loss of venous access is threatening for patients with intestinal failure (IF) under long-term parenteral nutrition (PN). We aimed to identify the incidence of central venous catheter (CVC) complications, compare different devices, and analyze interventional recanalizing procedures to restore the patency of occluded CVCs. METHODS: For this retrospective cohort study, patient data from a prospective IF database spanning 16 years was analyzed at a tertiary referral center. Catheter dwell times (CDTs) were distinguished by Kaplan-Meier survival analysis and subgroup analyses were performed for different CVC types (tunneled/port catheters). Specific complications (occlusion, catheter-related infection (CRI), displacement, and material defect) were analyzed. Explantation rates and CDTs were compared. RESULTS: Overall, 193 CVCs in 77 patients with IF under PN could be enrolled (62.524 "CVC-days"). Broviac type "B" was found to be significantly superior to type "A" regarding occlusion, CRI, and material defects (log-rank test: p = 0.05; p = 0.026; p = 0.005 respectively). Port catheters were displaying the highest incidence of CRI (2.13 events/1000 catheter days). Interventional catheter recanalization was performed 91 times and significantly increased the CDT from a median of 131 days (IQR: 62; 258) to 389 days (IQR: 262; 731) (Mann-Whitney-U-test: p= <0.001) without increasing complications. CONCLUSIONS: Different complication rates and CDT were seen depending on CVC type. Tunneled catheters were significantly superior concerning CRI. Interventional catheter recanalization is a viable alternative to fibrinolytics to restore CVC patency, but long-term patency data is scarce.

RESUMO

BACKGROUND: Venous access in patients with obesity presents significant challenges. The success of central venous catheterisation largely depends on the cross-sectional area (CSA) of the internal jugular vein (IJV). While techniques like the Trendelenburg position have been traditionally used to increase IJV CSA, recent studies suggest its ineffectiveness in patients with obesity. Conversely, the potential of the effect of passive leg raising (PLR) has not been thoroughly investigated in this group of patients. METHODS: This protocol outlines a planned randomised controlled trial to evaluate the effect of PLR on the CSA of the IJV in patients with obesity slated for central venous catheterisation. The protocol involves dividing 40 participants into two groups: one undergoing PLR and another serving as a control group without positional change. The protocol specifies measuring the CSA of the IJV via ultrasound as the primary outcome. Secondary outcomes will include the success rates of right IJV cannulation. The proposed statistical approach includes the use of t-tests to compare the changes in CSA between the two groups, with a significance threshold set at p<0.05. ETHICS APPROVAL: This study has been approved by the Institutional Review Board of Shanghai Tongren Hospital. All the participants will provide informed consent prior to enrolment in the study. Regarding the dissemination of research findings, we plan to share the results through academic conferences and peer-reviewed publications. Additionally, we will communicate our findings to the public and professional communities, including patient advocacy groups. TRIAL REGISTRATION NUMBER: ChiCTR: ChiCTR2400080513.

RESUMO

OBJECTIVES: This review aims to compare the performance of available risk assessment models (RAMs) for predicting peripherally inserted central catheter-related venous thrombosis (PICC-RVT) in adult patients with cancer. METHODS: A systematic search was conducted across ten databases from inception to October 20, 2023. Studies were eligible if they compared the accuracy of a RAM to that of another RAM for predicting the risk of PICC-RVT in adult patients with cancer. Two reviewers independently performed the study selection, data extraction and risk of bias assessments. A Bayesian network meta-analysis (NMA) was used to evaluate the performance of the RAMs. RESULTS: A total of 1931 studies were screened, and 7 studies with 10 RAMs were included in the review. The most widely used RAMs were the Caprini (4 studies), Padua prediction score (3 studies), Autar (3 studies), Michigan risk score (2 studies) and Seeley score (2 studies). The sensitivity, specificity and accuracy varied markedly between the models. Notably, the Caprini score achieved higher sensitivity than 4 RAMs (Wells, Revised Geneva, modified MRS, MRS). The Michigan risk score had greater specificity than did the other 6 RAMs (Caprini, Autar, Padua, Seeley, the novel RAM, Wells). The predictive accuracy of the MRS is significantly greater than that of the Caprini and Autar RAM. CONCLUSION: The MRS could be the most accurate RAM for identifying patients at high risk of PICC-RVT. However, as limited studies are available, more rigorous studies should be conducted to examine the accuracy of the Michigan risk score for PICC-RVT in different contexts.

RESUMO

OBJECTIVES: To evaluate the effectiveness of teaching-learning programs for cancer patients and/or their caregivers or family in preventing and controlling infections associated with long-term central venous access devices. DATA SOURCES: This systematic review used the CINAHL, Cochrane Library, EMBASE, LILACS, and MEDLINE via PubMed portal, Scopus, and Web of Science. Google Scholar was used for the gray literature search. The included studies were analyzed, and the obtained data were qualitatively synthesized. The risk of bias was assessed using Cochrane tools: RoB 2 and ROBINS-I. The certainty of the evidence was evaluated using the GRADE. The review protocol was registered in PROSPERO (CRD42021267530). CONCLUSION: The teaching-learning programs were implemented through theoretical-practical and theoretical dimensions in five and two studies, respectively. The risk of bias in the studies was low, moderate, severe, and high in one, three, two, and one of them, respectively. The certainty was very low. Teaching-learning programs on central venous access devices care for cancer patients and/or their caregivers or families could be effective in reducing infection rates. IMPLICATIONS FOR NURSING PRACTICE: This systematic review addressed the teaching-learning programs for preventing and controlling infections associated with long-term central venous access devices. We identified that the most programs were effective in reducing the infection rates. The results may influence the clinical practice of oncology nurses, and consequently, the educational strategies and methods provided not only to these patients but for caregivers and families.

RESUMO

BACKGROUND: When clinicians need to administer a vasopressor infusion, they are faced with the choice of administration via either peripheral intravenous catheter (PIVC) or central venous catheter (CVC). Vasopressor infusions have traditionally been administered via central venous catheters (CVC) rather than Peripheral Intra Venous Catheters (PIVC), primarily due to concerns of extravasation and resultant tissue injury. This practice is not guided by contemporary randomised controlled trial (RCT) evidence. Observational data suggests safety of vasopressor infusion via PIVC. To address this evidence gap, we have designed the "Vasopressors Infused via Peripheral or Central Access" (VIPCA) RCT. METHODS: The VIPCA trial is a single-centre, feasibility, parallel-group RCT. Eligible critically ill patients requiring a vasopressor infusion will be identified by emergency department (ED) or intensive care unit (ICU) staff and randomised to receive vasopressor infusion via either PIVC or CVC. Primary outcome is feasibility, a composite of recruitment rate, proportion of eligible patients randomised, protocol fidelity, retention and missing data. Primary clinical outcome is days alive and out of hospital up to day-30. Secondary outcomes will include safety and other clinical outcomes, and process and cost measures. Specific aspects of safety related to vasopressor infusions such as extravasation, leakage, device failure, tissue injury and infection will be assessed. DISCUSSION: VIPCA is a feasibility RCT whose outcomes will inform the feasibility and design of a multicentre Phase-3 trial comparing routes of vasopressor delivery. The exploratory economic analysis will provide input data for the full health economic analysis which will accompany any future Phase-3 RCT.

RESUMO

ABSTRACT: Central line-associated blood stream infections (CLABSIs) are a quality marker for the critical care environment. They have become an area of particular interest because they cost the healthcare system close to a billion dollars per year and have a significant impact on patient safety. Through a preliminary analysis of our system's CLABSI rates, we found significantly higher rates than the national average, prompting further investigation. We decreased our CLABSI rate by over 40% from 2021 (1.6 per 1,000 line days) to the fourth quarter of 2022 (0.91) and kept the rate below or around the national rate (0.86) for the last three quarters of 2022. Through looking at current outcome data, identifying key stakeholders, developing dedicated committees, conducting root cause analyses, monitoring progress, adjusting procedures, scaling to the system, and continuously monitoring and reporting results, we have shown the efficacy of this kind of quality improvement structure and strive to reduce our hospital system's impact on avoidable healthcare-associated patient harm.

RESUMO

INTRODUCTION: Deep Venous Thrombosis (DVT) due to Peripherally Inserted Central Catheter (PICC) is one of the most threatening complications after device insertion. OBJECTIVE: To assess the rate of PICC-associated DVT and analyze the risk factors associated with this event in cancer and critically ill patients. METHODS: We conducted a descriptive, retrospective cohort study with 11,588 PICCs from December 2014 to December 2019. Patients ≥ 18 years receiving a PICC were included. Pre-and post-puncture variables were collected and a logistic regression was used to identify the independent factors associated with the risk of DVT. RESULTS: The DVT prevalence was 1.8% (n = 213). The median length of PICC use was 15.3 days. The median age was 75 years (18; 107) and 52% were men, 53.5% were critically ill and 29.1% oncological patients. The most common indications for PICC's were intravenous antibiotics (79.1%). Notably, 91.5% of PICC showed a catheter-to-vein ratio of no more than 33%. The tip location method with intracavitary electrocardiogram was used in 43%. Most catheters (67.9%) were electively removed at the end of intravenous therapy. After adjusting for cancer profile ou chemotherapy, regression anaysis revealed that age (OR 1.011; 95% CI 1.002-1.020), previous DVT (OR 1.96; 95% CI 1.12-3.44) and obstruction of the device (OR 1.60; 95% CI 1.05-2.42) were independent factors associated with PICC-associated DVT, whereas the use of an anticoagulant regimen was a protective variable (OR 0.73; 95% CI 0.54-0.99). CONCLUSION: PICC is a safe and suitable intravenous device for medium and long-term therapy, with low rates of DVT even in a cohort of critically ill and cancer patients.
