Complications in the use of peripherally inserted central catheter associated with peripheral intravenous therapy: retrospective cohort.

OBJECTIVE: to analyze the occurrence of difficulty in the peripheral insertion of the central catheter and the presence of complications in the use of this device in hospitalized adults who received peripheral intravenous therapy through a short peripheral intravenous catheter and to identify whether there is an association between peripheral intravenous therapy and the presence of complications in the use of the peripherally inserted central catheter. METHOD: retrospective cohort, with patients aged 18 years or over, in a tertiary teaching hospital, with a peripherally inserted central catheter, who had at least one previous short peripheral intravenous catheter. Data were analyzed using descriptive statistics and Poisson regression. RESULTS: the sample consisted of 76 patients. There was an association between difficulty in the insertion procedure and number of punctures (p<0.01) and insertion in the external jugular vein compared to the upper limbs (p<0.01). The insertion site was also associated with the removal of the peripherally inserted central catheter due to complications in the robust analysis of variance (p=0.02). No associations were identified between: difficulty inserting the device and time on peripheral intravenous therapy (crude model p=0.23; adjusted model p=0.21); difficulty in insertion with administration of irritating and vesicant medication (crude model p=0.69; adjusted model p=0.53); complication in the use of peripherally inserted central catheter and time of peripheral intravenous therapy (crude and adjusted models p=0.08); and secondary migration of the catheter tip with the device insertion site (p=0.24). CONCLUSION: it was possible to identify secondary migration as one of the main complications, resulting in premature removal of the device. Furthermore, the greater the number of puncture attempts to insert the PICC, the greater the difficulty in inserting it. Insertion into the external jugular vein was recurrent, with a higher risk of removal due to complications in relation to the upper limbs.

Comment on: "Operator gender differences in major mechanical complications after central line insertions: a subgroup analysis of a prospective multicentre cohort study".

We read with great interest the recent study by Naddi et al. in BMC Anesthesiology, which explores operator gender differences in major mechanical complications following central venous catheterization. The study identifies male operator gender as an independent risk factor for complications. However, our attempt to replicate these findings using Colombian data did not support this association. We caution against oversimplifying the influence of sex and gender on health outcomes, as numerous factors, including cultural norms, healthcare practices, and resource availability, significantly impact procedural outcomes. Differences in complication rates may reflect risk-taking behaviors and systemic healthcare disparities rather than inherent biological differences. We emphasize the need for a comprehensive approach to understand the multifaceted nature of central venous related complications. Replication studies across diverse populations are crucial for validating these findings and informing effective strategies for complication prevention and management.

Bacteriemia asociada a catéteres venosos centrales no tunelizados en niños en hemodiálisis crónica / Bacteremia associated with non-tunneled central venous catheters in children undergoing chronic hemodialysis

Introducción. La infección asociada a catéter venoso central (CVC) es la principal complicación que presentan los pacientes en hemodiálisis en los que se usa este tipo de acceso. Objetivo. Estimar la incidencia de bacteriemia asociada a CVC no tunelizado, analizar la frecuencia de agentes causales y explorar factores de riesgo asociados en niños en hemodiálisis. Población y métodos. Estudio retrospectivo realizado en niños en hemodiálisis por CVC no tunelizado entre el 1 junio de 2015 y el 30 de junio de 2019. Para evaluar factores de riesgo predictores de bacteriemia asociada a CVC, se realizó regresión logística. Los factores de riesgo independiente se expresaron con odds ratio con sus respectivos intervalos de confianza del 95 %. Se consideró estadísticamente significativo un valor de p <0,05. Resultados. En este estudio se incluyeron 121 CVC no tunelizados. La incidencia de bacteriemia fue de 3,15 por 1000 días de catéter. El microorganismo aislado con mayor frecuencia fue Staphylococcus epidermidis (16 casos, 51,5 %). La infección previa del catéter fue el único factor de riesgo independiente encontrado para el desarrollo de bacteriemia asociada a CVC no tunelizado (OR: 2,84; IC95%: 1,017,96; p = 0,04). Conclusiones. El uso prolongado de los CVC no tunelizados para hemodiálisis crónica se asoció con una incidencia baja de bacteriemia. Los gérmenes grampositivos predominaron como agentes causales. La presencia de infección previa del CVC aumentó en casi 3 veces el riesgo de bacteriemia asociada a CVC en nuestra población pediátrica en hemodiálisis.

Introduction. Central venous catheter (CVC)-related infection is the main complication observed in patients undergoing hemodialysis with this type of venous access. Objective. To estimate the incidence of non-tunneled CVC-related bacteremia, analyze the frequency ofcausative agents, and explore associated risk factors in children undergoing hemodialysis. Population and methods. Retrospective study in children receiving hemodialysis via a non-tunneled CVC between June 1 st, 2015 and June 30 th, 2019. A logistic regression was carried out to assess risk factors that were predictors of CVC-related bacteremia. Independent risk factors were described as odds ratios with their corresponding 95% confidence interval (CI). A value of p < 0.05 was considered statistically significant. Results. A total of 121 non-tunneled CVCs were included in this study. The incidence of bacteremia was 3.15 per 1000 catheter-days. The most commonly isolated microorganism was Staphylococcus epidermidis(16 cases, 51.5%). Prior catheter infection was the only independent risk factor for the development of bacteremia associated with non-tunneled CVC (OR: 2.84, 95% CI: 1.01­7.96, p = 0.04). Conclusions. Prolonged use of non-tunneled CVCs for chronic hemodialysis was associated with a low incidence of bacteremia. Gram-positive microorganisms prevailed among causative agents. A prior CVC infection almost trebled the risk for CVC-related bacteremia in our pediatric population receiving hemodialysis.

Prevention of complications related to peripherally inserted central catheter insertion techniques in newborns: systematic review and network meta-analysis.

OBJECTIVE: to analyze the effectiveness of peripherally inserted central catheter insertion techniques in preventing the occurrence of complications related to this device in newborns. METHOD: a paired and network systematic literature review and meta-analysis, with its search carried out in seven databases and in the Grey Literature, including randomized and non-randomized clinical trials. The risk of bias was assessed using the Cochrane Risk of Bias 2 and Risk of Bias In Non-randomized Studies of Interventions tools. Certainty of the evidence was assessed by means of the Grading of Recommendations Assessment, Development and Evaluation. A meta-analysis was carried out with the aid of the R statistical program. RESULTS: eight studies with 1,126 newborns were included and six insertion techniques were identified: intracavitary electrocardiogram; intracavitary electrocardiogram associated with ultrasound; ultrasound; formula; anatomical landmark; and modified anatomical landmark. Five techniques significantly decreased primary tip malpositioning when compared to the control ( p <0.05). Intracavitary electrocardiogram significantly and more effectively reduced arrhythmias, general complications and phlebitis; the technique that used a formula also reduced general complications. Infection, infiltration, secondary tip malpositioning, catheter rupture, thrombosis, occlusion and catheter-associated skin lesion were not significantly preventable events. CONCLUSION: intracavitary electrocardiogram and use of the formula were the most effective techniques in reducing complications.

Central line-associated bloodstream infections in patients with COVID-19.

OBJECTIVE: to investigate the association between central line-associated bloodstream infections and clinical and care variables of intensive care unit patients with COVID-19 hospitalized at a reference public health institution. METHOD: a case-control study. RESULTS: the study sample consisted of 70 patients diagnosed with central line-associated bloodstream infections (case group) and 70 non-infected patients (control group). Most patients were male, with mean age of 57.93±13.93 years old and provided with a double lumen catheter. Median time of central line-associated bloodstream infections onset was 11 (8-18) days. Longer time on mechanical ventilation ( P =0.014; OR: 1.79; 95% CI: 0.91-3.51) and prone position ( P =0.017; OR: 2.41; 95% CI: 1.22-4.81) were associated with central line-associated bloodstream infections onset. CONCLUSION: longer time on invasive mechanical ventilation and prone position contributed to central line-associated bloodstream infections onset in COVID-19 patients.

Reducing CLABSI through a quality strategy for the implementation of the aseptic non-touch technique in a pediatric ward.

BACKGROUND: Central line-associated bloodstream infections (CLABSIs) are among the most epidemiologically relevant health care-associated infections. The aseptic non-touch technique (ANTT) is a standardized practice used to prevent CLABSIs. In a pediatric hospital, the overall CLABSI rate was 1.92/1000 catheter days (CD). However, in one unit, the rate was 5.7/1000 CD. METHODS: Nurses were trained in ANTT. For the implementation, plan-do-study-act (PDSA) cycles were completed. Adherence monitoring of the ANTT and epidemiological surveillance were performed. RESULTS: ANTT adherence of 95% was achieved after 6 PDSA cycles. Hand hygiene and general cleaning reached 100% adherence. Port disinfection and material collection had the lowest adherence rates, with 76.2% and 84.7%, respectively. The CLABSI rate decreased from 5.7 to 1.26/1000 CD. CONCLUSION: The implementation of ANTT helped reduce the CLABSI rate. Training and continuous monitoring are key to maintaining ANTT adherence.

Prevalence of PICC-related thrombosis in patients with hematological malignancies: a systematic review.

PURPOSE: To estimate the prevalence of peripherally inserted central catheter (PICC)-related venous thrombosis in patients with hematological malignancies. METHODS: A systematic review of observational studies that evaluated the occurrence of PICC-related venous thrombosis in children, adults, and older people with hematological malignancies was conducted. Searches were carried out on June 12th, 2023 on PubMed, CINAHL, Embase, Web of Science Core Collection, Scopus, and LILACS, and to gray literature on Google Scholar, and ProQuest Dissertations and Theses Global. Eligibility criteria were applied independently by two reviewers, first on the titles and abstracts on the Rayyan platform and then on the full text of eligible studies. Risk of bias was assessed by the JBI checklist. Data were summarized descriptively, and the meta-analysis was carried out using the MetaXL 5.3 software. The review followed JBI guidelines and PRISMA for reporting. RESULTS: In the 40 studies included, prevalence of PICC-related venous thrombosis was 9% in general, 9% in adults, and 6% in children with hematological malignancies. Most studies only evaluated cases of symptomatic thrombosis (n = 25; 64%). CONCLUSION: Patients with hematological malignancies using PICC have an estimated prevalence of PICC-related venous thrombosis of 9%, and this rate may be underestimated due to the consideration of mostly symptomatic cases.

PiccPed® app impact on nurses' knowledge to prevent adverse events for peripherally inserted central catheters (PICC) in pediatric and neonatal healthcare: A quasi-experimental study.

BACKGROUND: The PiccPed® health application was developed to support clinical decision-making in peripherally inserted central catheter (PICC) management. We aimed to evaluate its impact on nurses' knowledge regarding the prevention of PICC-associated adverse events in pediatrics and neonatology. METHODS: A quasi-experimental, pre-post intervention study, was conducted with a dependent/paired sample of pediatric and neonatal nurses from two tertiary hospitals in South Brazil. Data were collected from October 2022 to January 2023 across three phases: pre-, intervention (use of the PiccPed®) and post-test. Study outcomes were a knowledge test (15 questions) of evidence-based PICC maintenance procedures, and PiccPed® app time spent and screens used. RESULTS: A total of 56 nurses completed the study. The post-test mean score was significantly higher (12/15; standard deviation (SD) 1.9) in comparison with the pre-test (mean 9/15; SD 2.2). The change in scores was significantly higher for nurses without postgraduate qualifications, in comparison to those with (Mean Difference 1.26; p = 0.039). Each minute using the app resulted in a significant increase of 0.04 points (95% confidence interval 0.01-0.08; p = 0.014) on the mean post-test score (10.94 points). CONCLUSION: The research demonstrated that PiccPed® enhances nurses' learning regarding the prevention of adverse events associated with PICC maintenance in pediatrics and neonatology. APPLICATION TO PRACTICE: The app can be safely and effectively used for training and continuing education of nurses who care for children and neonates with PICCs.

Risk of deep venous thrombosis associated with peripherally inserted central catheter: A retrospective cohort study of 11.588 catheters in Brazil.

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.

The Use of a High Flow PICC Catheter for Stem Cell and Lymphocyte Apheresis: The Initial Experience of a Pediatric Oncology Center in Brazil.

BACKGROUND: Autologous hematopoietic stem cell transplant (HSCT), characterized by high intensity chemotherapy followed by the infusion of HSC previously collected from the peripheral blood, is a procedure used in the treatment of several malignancies. In pediatrics, the apheresis procedure represents a challenge, due to the need for insertion of a rigid central venous catheter (CVC) in small children. The CVC is usually used for stem cell collection and then removed. Later, the patient will need a new device for cell infusion. AIM: We propose the use of one single catheter for both apheresis and infusion. METHODS: We present five children between 1 and 13 years of age who underwent apheresis using a high flow PICC catheter surgically inserted. RESULTS: All patients utilized a PICC line double lumen 5Fr (PowerPICC™ 5Fr DL BARD/USA) placed in the brachiocephalic vein tunneled on the chest, inserted under 24 h prior to apheresis to assure the devices were pervious. Three of the patients were diagnosed with solid tumor and one with acute lymphoblastic leukemia (ALL) awaiting Car-T Cell therapy. The four children who underwent autologous HSCT used the same catheter for cell infusion and remained with the catheter following discharge. The child who was submitted for Car-T Cell still awaits infusion and the catheter was removed. CONCLUSIONS: High flow PICC is a viable alternative for apheresis to maintain an adequate flow of 5 ml/s and can be used as a single catheter throughout the HSCT process, reducing the risks from anesthesia and the catheter insertion procedure. TYPE OF STUDY: Clinical Research.

Peripherally Inserted Central Catheter Versus Centrally Inserted Central Catheter for In-Hospital Infusion Therapy: A Cost-Effectiveness Analysis.

OBJECTIVES: To evaluate the comparative effectiveness and cost-effectiveness of peripherally inserted central catheters (PICCs) compared with centrally inserted central catheters (CICCs). METHODS: Prospective cohort study was followed by an economic analysis over a 30-day time horizon. Propensity score matching was used to select hospitalized adults with similar indications for PICC or CICC. The composite outcome was device removal or replacement because of complications before the end of treatment. The economic evaluation was based on a decision tree model for cost-effectiveness analysis, with calculation of the incremental cost-effectiveness ratio (ICER) per catheter removal avoided. All costs are presented in Brazilian reais (BRL) (1 BRL = 0.1870 US dollar). RESULTS: A total of 217 patients were followed in each group; 172 (79.3%) of those receiving a PICC and 135 (62.2%) of those receiving a CICC had no device-related complication, respectively. When comparing the events leading to device removal, the risk of composite endpoint was significantly higher in the CICC group (hazard ratio 0.20; 95% CI 0.11-0.35). The cost of PICC placement was BRL 1290.98 versus BRL 467.16 for a CICC. In the base case, the ICER for placing a PICC instead of a CICC was BRL 3349.91 per removal or replacement avoided. On univariate sensitivity analyses, the model proved to be robust within an ICER range of 2500.00 to 4800.00 BRL. CONCLUSIONS: PICC placement was associated with a lower risk of complications than CICC placement. Although the cost of a PICC is higher, its use avoided complications and need for catheter replacement before the end of treatment.

Content validity of an instrument for analysing nurses' knowledge of peripherally inserted central catheters.

Peripherally inserted central catheters (PICCs) ensure safe and long-lasting venous access. Using validated instruments to assess nurses' knowledge of PICC use will allow educational measures to improve this area of care to be developed. OBJECTIVE: This study aimed to build an instrument for analysing nurses' knowledge about PICCs and assess its content validity. METHODS: A psychometric study was used with the construction of a knowledge analysis instrument. This was developed in two stages: instrument construction; and content validation by expert judges using the content validity ratio. RESULTS: The panel of experts comprised nine nurses. Nineteen changes related to content and semantics were suggested for the instrument. CONCLUSION: The research allowed for the construction and validation of a tool for knowledge analysis; this is relevant to practice as no such knowledge instrument exists. It is proposed to use this assessment instrument to identify gaps in knowledge and implement focused training interventions.

[Ultrasound-guided insertion and the proportion of catheter-associated thrombosis]. / Inserción con técnica ecoguiada y la proporción de trombosis asociada a catéter.

Background: Central venous accesses are of great importance in daily medical practice. Insertion into the jugular vein is common due to its accessibility. Catheter-associated venous thrombosis is a relatively common medium-term complication. The use of ultrasound to guide catheterization offers multiple advantages and promises to make vascular access installation a safer technique. Objective: To compare the proportion of catheter-associated jugular thrombosis when an anatomical landmark technique is used with respect to the ultrasound-guided technique. Material and methods: An observational, cross-sectional, and analytical study that compares the frequency of thrombosis when the ultrasound-guided technique was used concerning anatomical reference technique in patients in an intensive care unit. Results: A total of 91 patients were studied: in 44 an ultrasound-guided technique was used, and in 47 anatomical references. A single case of mural thrombosis (2.7%) was observed in the ultrasound-guided insertion group vs. 11 cases (23.4%) in the other group, resulting in a significant association between the anatomical reference insertion technique and thrombosis. Chi squared (1, n = 91) = 8.86, p = 0.004. Conclusion: The proportion of catheter-associated jugular thrombosis is greater when an anatomical reference technique is used compared to the ultrasound-guided technique.

OBJECTIVES: to assess the effect of an educational intervention based on clinical simulation on nursing professionals' compliance with practices to prevent peripherally inserted central venous catheter-associated primary bloodstream infections in a Neonatal Intensive Care Unit. METHODS: a quasi-experimental study, with preand post-intervention assessment with a single group. The population consisted of 41 nursing professionals, with 31 observations being made before and after the intervention. Analyzes were performed using descriptive statistics and the McNemar non-parametric test. A significance level of 5% was adopted. RESULTS: after the intervention, there was an increase in compliance with prevention practices of surgical antisepsis and professional hand hygiene, skin antisepsis with chlorhexidine, waiting for the time of the effect of alcoholic chlorhexidine and compliance with the sterile technique. CONCLUSIONS: the educational intervention showed an effect on increasing compliance with catheter-associated infection prevention practices.

Follow up of utility and value of totally implantable chemotherapy catheter in 233 brazilian patients receiving chemotherapy to treat cancer.

OBJECTIVES: the present study aims to evaluate cancer patients related to the catheter flow and the general satisfaction of these patients. METHODS: we studied 233 individuals diagnosed with cancer who underwent chemotherapy treatment through venous access through portocath between January 2015 and December 2019. RESULTS: 97% of the patients consulted had palliative chemotherapy, and 99.1% of patients reported satisfaction with the implantation process and treatment method. Regarding catheter flow according to venous return and drip during drug infusion, 98.7% of individuals presented good flow. CONCLUSIONS: the results show that catheter flow was satisfactory in all implant sites observed and emphasize the advantages of using a totally implanted catheter. This benefice happens due to the reduction of emotional factors that cause stress in cancer patients receiving chemotherapy, as well as the reduction of trauma and discomfort experienced by patients during the infusion of peripheral chemotherapy.

Implementation of modified Seldinger technology for percutaneous catheterization in critically ill newborns.

OBJECTIVE: To describe the implementation of Modified Seldinger Technology for percutaneous catheterization in critically ill newborns. METHOD: A quasi-experimental before- and-after study, carried out with neonatologist nurses in a Neonatal Intensive Care Unit. RESULTS: Seven nurses participated in the research. Catheter pre-insertion, insertion and maintenance were assessed using the conventional and modified Seldinger technique. Reliability was satisfactory in pre-test, 5.40 (Md = 6.00), and post-test, 5.94 (Md = 7.00), and perfect in the items about device insertion and maintenance. There was low assertiveness in the items on indication, microintroduction procedure via ultrasound, limb repositioning and disinfection of connections/connectors. CONCLUSION: Despite the Modified Seldinger Technique expanding some stages of execution over the traditional method of percutaneous catheterization, nurses were more assertive after theoretical-practical training. The technology was implemented and is in the process of being implemented in the health service.
