Sellado antibiótico de reservorios subcutáneos: estabilidad de soluciones con vancomicina / Antimicrobial lock solutions for implantable central venous devices: stability of vancomycin solutions

Los reservorios subcutáneos son un tipo de catéter venoso central (CVC). Cuando se usan catéteres venosos centrales (CVC), el personal sanitario necesita evitar dos grandes riesgos: formación de coágulos e infecciones bacterianas. Para prevenir y evitar la contaminación de los catéteres en los pacientes hospitalizados y ambulatorios, se han implementado diversas alternativas, como el llamado “sellado antibiótico de catéteres” (SAC). De este modo, se ha sugerido la utilización de soluciones con agentes antimicrobianos, a las que se suelen adicionar sustancias con efecto anticoagulante y/o con efecto antibiofilm. Empero, se requiere que la estabilidad de dichas soluciones sea comprobada mediante técnicas como la cromatografía líquida de alta resolución (HPLC), además de las pruebas de eficacia antimicrobiana, para así poder establecer la seguridad de los pacientes. En este entorno, se plantea el presente trabajo de revisión bibliográfica, con el objetivo de incluir las investigaciones de mayor representación clínica a este respecto, para evidenciar el comportamiento de las soluciones de sellado antibiótico de catéteres en distintas condiciones de almacenamiento y uso. En particular, esta revisión se centra en soluciones con vancomicina. De acuerdo con los estudios consultados, las soluciones de vancomicina con citrato de sodio (agente quelante) son las que presentan las mejores características en cuanto a estabilidad físico-química y eficacia como soluciones de sellado.(AU)

Subcutaneous reservoirs are a type of central venous catheter. When using central venous catheters, healthcare workers need to avoid two major risks: clot formation and bacterial infections. To prevent and avoid catheter contamination in both hospitalized patients and outpatients, several strategies have been carried out, such as the so-called ” antibiotic-based catheter lock solution”. Therefore, it has been suggested to implement the use of solutions with antimicrobial agents, to which anticoagulant and/or antibiofilm substances are often added.However, the stability of such solutions needs to be tested by techniques such as high performance liquid chromatography (HPLC), in addition to antimicrobial efficacy testing, in order to establish patient safety. In consequence, this literature review aims to include the most clinically representative research towards these aspects, to demonstrate the behaviour of antibiotic-based catheter lock solutions under different conditions of storage and use. In particular, this review focuses on solutions containing vancomycin. According to the studies consulted, vancomycin solutions with sodium citrate (chelating agent) present the best stability characteristics in terms of physicochemical properties and efficacy.(AU)

The curative effect analysis of peripherally inserted central venous catheter catheterization for tumor patients under the guidance of new medical guide wire.

OBJECTIVE: To report a method of PICC catheterization with the aid of a new medical guide wire, and to discuss the curative effect. METHODS: Five hundred and thirteen patients who visited our hospital from January 2013 to December 2019 for PICC catheterization were selected as study subjects. Random number method was used to group patients. General information was recorded for both groups. Patients in the observation group received catheterization with the aid of a new medical guide wire. The control group received catheterization via conventional guide wire. The success rate of the first catheterization, the success rate of the catheterization, the timing of the catheterization, the complications and the position of the catheter end were compared between the two groups. RESULTS: There was no significant difference in general information between the two groups. After analyzing the puncture situation of the two groups, it was found that the average catheterization time of the observation group was shorter than that of the control group, and the difference was statistically significant. Patients in the observation group had higher success rate of one-time catheterization and catheterization success rate, and the difference was statistically significant. The incidences of occult thrombosis, phlebitis and catheter blockage in the observation group were lower than those in the control group, and the difference was statistically significant. The incidence of dominant thrombosis and bleeding at puncture point in the observation group was also lower than that in the control group, but the difference was not statistically significant. CONCLUSION: The new type of medical guide wire component is effective for PICC catheterization and worthy of further promotion.

Central venous catheter insertion: Review of recent evidence.

Guidelines for prevention of catheter-related bloodstream infection (CR-BSI) describe a series of recommendations for correct insertion and handling of central venous catheters (CVCs). Since their implementation, quality programs such as "Zero bacteremia" have achieved a reduction in CR-BSI rates, but there is still room for further improvement. New evidence is emerging regarding, e.g., antiseptic-antimicrobial impregnated catheters or the use of passive disinfection of closed connectors. These examples of new tools among others might help to further decrease infection rates. This article aims to review new evidence-based strategies to reduce catheter insertion-related infection.

Novel Neonatal Umbilical Catheter Protection and Stabilization Device in In vitro Model of Catheterized Human Umbilical Cords: Effect of Material and Venting on Bacterial Colonization.

OBJECTIVE: Umbilical central lines deliver life-saving medications and nutrition for neonates; however, complications associated with umbilical catheters (UCs) occur more frequently than in adults with central lines (i.e., line migration, systemic infection). We have developed a device for neonatal UC protection and stabilization to reduce catheter exposure to bacteria compared with the standard of care: "goal post" tape configuration. This study analyzes the effect of device venting and material on bacterial load of human umbilical cords in vitro. STUDY DESIGN: Catheters were inserted into human umbilical cord segments in vitro, secured with plastic or silicone vented prototype versus tape, and levels of bacterial colonization were compared between groups after 7 days of incubation. RESULTS: Nonvented plastic prototype showed increased bacterial load compared with goal post (p = 0.04). Colonization was comparable between the goal post and all vented plastic prototypes (p ≥ 0.30) and when compared with the vented silicone device (p = 1). CONCLUSION: A novel silicone device does not increase external bacterial colonization compared with the current standard of care for line securement, and may provide a safe, convenient alternative to standard adhesive tape for UC stabilization. Future studies are anticipated to establish safety in vivo, alongside benefits such as migration and infection reduction.

Central venous catheter-related infections in hematology and oncology: 2020 updated guidelines on diagnosis, management, and prevention by the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO).

Cancer patients frequently require central venous catheters for therapy and parenteral nutrition and are at high risk of central venous catheter-related infections (CRIs). Moreover, CRIs prolong hospitalization, cause an excess in resource utilization and treatment cost, often delay anti-cancer treatment, and are associated with a significant increase in mortality in cancer patients. We therefore summoned a panel of experts by the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO) and updated our previous guideline on CRIs in cancer patients. After conducting systematic literature searches on PubMed, Medline, and Cochrane databases, video- and meeting-based consensus discussions were held. In the presented guideline, we summarize recommendations on definition, diagnosis, management, and prevention of CRIs in cancer patients including the grading of strength of recommendations and the respective levels of evidence. This guideline supports clinicians and researchers alike in the evidence-based decision-making in the management of CRIs in cancer patients.

Durability of tunneled catheters in children is associated with catheter tip depth: A single-center report.

The aim of this study was to examine the impact of different catheter tip positions on catheter duration and dysfunction of tunneled catheters in children. Catheters were evaluated for place of insertion, time of insertion, catheter tip depth and position, duration of use, and reason for removal. The mean duration of implanted catheters with tips placed in cavo-atrial junction/right atrium was significantly longer with significantly lower percentage of complications than tips placed in superior vena cava. Only catheter tips placed in cavo-atrial junction/right atrium was a predictor of catheter functionality and survival. Shorter catheter survival in children with tunneled catheters is a consequence of a catheter tip depth proximal of CAJ and RA. Our results showed that the main factor responsible for better catheter functionality was not laterality but the depth of the catheter tip, which reduces need for future catheter insertions with increased catheter durability.

Sistematização de arranjo institucional para a segurança e qualidade do manejo de cateteres venosos centrais / Systematization of institutional arrangements for the safety and quality of central venous catheter management

INTRODUÇÃO: A complexidade e relevância da terapia infusional venosa exige que as equipes de saúde tenham processos de cuidado seguros e de qualidade, especialmente aqueles que envolvem o manejo dos cateteres venosos centrais. OBJETIVO: Propor estratégias organizacionais para favorecer a segurança e a qualidade do manejo dos cateteres venosos centrais no cuidado a crianças cirúrgicas internadas em unidades especializadas. MÉTODO: Adotou-se a metodologia de pesquisa estratégica em saúde, no âmbito da gestão clínica, focando o processo de trabalho envolvido no manejo do cateter venoso central para a melhoria contínua do cuidado prestado. O cenário da pesquisa foi a Área de Atenção à Criança Cirúrgica do Instituto Nacional de Saúde da Mulher, da Criança e do Adolescente Fernandes Figueira. Primeira técnica de pesquisa: inquérito realizado com os profissionais desta área, através de plataforma de pesquisa digital, baseado nas medidas consideradas como padrão ouro para a prevenção da infecção da corrente sanguínea relacionada ao cateter venoso central. Segunda técnica: discussão acerca dos processos no manejo do cateter venoso central, em encontro com os gestores das UPs da Área de Atenção à Criança Cirúrgica para sistematização dos pontos críticos. RESULTADOS: Os achados do inquérito são consistentes e coerentes com os aspectos ressaltados pela liderança do serviço. Foi identificada variação das respostas entre as categorias, sendo o melhor desempenho dos enfermeiros e pediatras. Duas questões foram particularmente desafiadoras: uso da clorexidina no preparo da pele escolhida por 7% dos respondentes e somente 1 pediatra responde adequadamente a ordem de escolha para inserção. Os nós críticos levantados pela liderança foram: qualidade do material, uso mais adequado da clorexidina e protocolo de analgesia para inserção. CONCLUSÃO: A distância entre a literatura e a prática de cuidado ficou evidenciado pelo estudo e identificou-se recomendações para outros serviços, onde a reflexão persiste em apoiar os profissionais de serviços especializados na busca da efetividade clínica. Para isso, a prática precisa ser coerente, segura e sistematizada à luz da literatura para então otimizar a tecnologia disponível em cada serviço, alcançando a eficácia e respeitando a relação custo-benefício em cada realidade no Sistema Único de Saúde (SUS).

INTRODUCTION: The complexity and relevance of venous infusion therapy requires that health teams have safe and quality care processes, especially those involving the management of central venous catheters. OBJECTIVE: To propose organizational strategies to promote safety and quality in the management of central venous catheters in the care of surgical children admitted to specialized units. METHOD: A strategic health research methodology was adopted, within the scope of clinical management, focusing on the work process involved in the management of the central venous catheter for the continuous improvement of the care provided. The research setting was the Surgical Child Care Area of the Fernandes Figueira National Institute of Women's, Children and Adolescents' Health. First research technique: a survey carried out with professionals in this area, through a digital research platform, based on measures considered as the gold standard for the prevention of bloodstream infection related to the central venous catheter. Second technique: discussion about the processes in the management of the central venous catheter, in a meeting with the managers of the UPs of the Surgical Child Care Area to systematize the critical points. RESULTS: The survey findings are consistent and coherent with the aspects highlighted by the service leadership. Variation of responses between categories was identified, with the best performance of nurses and pediatricians. Two questions were particularly challenging: use of chlorhexidine in skin preparation chosen by 7% of respondents and only 1 pediatrician adequately answered the order of choice for insertion. The critical points raised by the leadership were: material quality, more appropriate use of chlorhexidine and analgesia protocol for insertion. CONCLUSION: The distance between the literature and the practice of care was evidenced by the study and recommendations for other services were identified, where the reflection persists in supporting professionals from specialized services in the search for clinical effectiveness. For this, the practice needs to be coherent, safe and systematized in the light of the literature to then optimize the technology available in each service, achieving effectiveness and respecting the cost-benefit ratio in each reality in the Unified Health System (SUS).

Usability Assessment of an Innovative Device in Infusion Therapy: A Mix-Method Approach Study.

Background: Flushing a venous access device is an important procedure to maintain their patency and prevent malfunctioning and complications. An innovative double-chamber syringe was developed, allowing for the assessment of catheter patency, drug delivery and final flush. This study aims to assess the usability of this new device, considering three development stages (concept, semi-functional prototype, functional prototype). Methods: An iterative methodology based on a mix-method design (qualitative and quantitative) enabled the assessment of the devices' usability by their primary end-users. A usability questionnaire was developed and applied, along with focus groups and individual interviews to nurses. Results: The usability questionnaire integrated 42 items focused on four dimensions (usefulness; ease of use; ease of learning; satisfaction and intention to use). The initial psychometric findings indicate a good internal consistency and the conceptual relevance of the items. The scores seem to be sensitive to the usability evaluation of the medical devices in different stages of product development (with lower values on functional prototype evaluation), and related to nurses' perceptions about functional and ergonomic characteristics. Conclusions: Quantitative and qualitative data provided a comprehensive overview of the double-chamber syringes' usability from the nurses' point of view, informing us of features that must be addressed.

Evaluating the Impact of Central Venous Catheter Materials and Design on Thrombosis: A Systematic Review and Meta-Analysis.

BACKGROUND: Thrombosis is a common complication associated with central venous catheter (CVC) insertion. Several antithrombogenic materials and alterations to catheter design have been developed to lower thrombosis rates. AIM: To systematically evaluate the effectiveness and safety of antithrombogenic materials and alterations to CVC design on thrombosis rates. METHODS: A systematic search was completed of main databases (CINAHL, EMBASE, MEDLINE, and PubMed) as well as trial registries and gray literature. Randomized controlled trials conducted in any age group, published in English language since 2008 reporting impact of different CVC designs or materials on thrombosis were included, to capture studies that reflect contemporary products and practice. Cochrane systematic review methodology was followed, including independent study selection and data extraction. Quality appraisal was conducted using the Cochrane risk of bias tool. A narrative synthesis and meta-analysis in RevMan were conducted. RESULTS: From a possible 232 studies, nine studies met the inclusion criteria. Four studies (n = 1,320) assessed different catheter materials; four studies (n = 591) compared different CVC designs, and one study (n = 150) evaluated impact of combined design and material on outcomes. Meta-analysis demonstrated that neither catheter material nor design alone or in combination had a significant impact on thrombosis (RR: 0.98 [95% CI 0.87, 1.11]). Different catheter materials and design also had no significant impact on occlusion or CRBSI. Studies were of mixed quality overall. LINKING EVIDENCE TO ACTION: Different CVC materials and designs were not associated with a reduction in the risk of either catheter-related thrombosis or infection. Overall reporting and small sample sizes make it difficult to draw firm conclusions. Larger, quality randomized trials are required to provide evidence about the possible merits of innovative catheter design and materials on patient outcomes.

Effects of blood flow on the antibacterial efficacy of chlorhexidine and silver sulfadiazine coated central venous catheter: A simulation-based pilot study.

BACKGROUND: Chlorhexidine and silver sulfadiazine coated central venous catheters (CSS-CVC) may cause loss of antimicrobial efficacy due to friction between the CVC surface and sheer stress caused by the blood flow. Therefore, the aim of this study was to investigate the antibacterial efficacy of CSS-CVC at various flow rates using a bloodstream model. METHODS: Each CVC was subjected to various flow rates (0.5, 1, 2, and 4 L/min) and wear-out times (0, 24, 48, 72, 96, and 120 hours), and the optical density (OD) 600 after a Staphylococcus aureus incubation test was used to determine the antibacterial effect of CSS-CVC. RESULTS: In the 0.5 L/min group, there was no significant change in the OD600 value up to 120 hours compared with the baseline OD600 value for CSS-CVC (P > .467). However, the OD600 values of CSS-CVC in the 1 L/min (P < .001) and 2 L/min (P < .001) groups were significantly reduced up to 72 hours, while that in the 4 L/min (p < 0.001) group decreased rapidly up to 48 hours. CONCLUSION: This study suggests that there is a doubt whether sufficient antibacterial function can be maintained with prolonged duration of catheter placement.

Misplacement of the tunnel hemodialysis catheter through the left jugular vein to the azygos vein: A case report.

RATIONALE: The percutaneous catheterization of central veins is widely applied in patients with end-stage renal diseases as a permanent vascular access. To our knowledge, inadvertent placement of a hemodialysis catheter into the azygos vein through the left internal jugular vein is not described. PATIENT CONCERNS: A 72-year-old female patient was admitted to the hospital for replacement of another new tunneled hemodialysis catheter due to poor flow in the left internal jugular vein tunneled catheter during hemodialysis. DIAGNOSIS: The catheter tip was incorrectly positioned into the azygos vein as confirmed by conventional anteroposterior and lateral chest radiographs. INTERVENTIONS: The catheter was removed and replaced under Digital Subtraction Angiography. OUTCOMES: The catheter tip was finally placed in the proper position. LESSIONS: The insertion of central vein catheterization is not always in suitable position especially through left jugular vein in hemodialysis patients. DSA technology should be performed to confirm the correct position of the tip and to ensure good blood flow.

Ultrasound to Detect Central Venous Catheter Placement Associated Complications: A Multicenter Diagnostic Accuracy Study.

BACKGROUND: Mechanical complications arising after central venous catheter placement are mostly malposition or pneumothorax. To date, to confirm correct position and detect pneumothorax, chest x-ray film has been the reference standard, while ultrasound might be an accurate alternative. The aim of this study was to evaluate diagnostic accuracy of ultrasound to detect central venous catheter malposition and pneumothorax. METHODS: This was a prospective, multicenter, diagnostic accuracy study conducted at the intensive care unit and postanesthesia care unit. Adult patients who underwent central venous catheterization of the internal jugular vein or subclavian vein were included. Index test consisted of venous, cardiac, and lung ultrasound. Standard reference test was chest x-ray film. Primary outcome was diagnostic accuracy of ultrasound to detect malposition and pneumothorax; for malposition, sensitivity, specificity, and other accuracy parameters were estimated. For pneumothorax, because chest x-ray film is an inaccurate reference standard to diagnose it, agreement and Cohen's κ-coefficient were determined. Secondary outcomes were accuracy of ultrasound to detect clinically relevant complications and feasibility of ultrasound. RESULTS: In total, 758 central venous catheterizations were included. Malposition occurred in 23 (3.3%) out of 688 cases included in the analysis. Ultrasound sensitivity was 0.70 (95% CI, 0.49 to 0.86) and specificity 0.99 (95% CI, 0.98 to 1.00). Pneumothorax occurred in 5 (0.7%) to 11 (1.5%) out of 756 cases according to chest x-ray film and ultrasound, respectively. In 748 out of 756 cases (98.9%), there was agreement between ultrasound and chest x-ray film with a Cohen's κ-coefficient of 0.50 (95% CI, 0.19 to 0.80). CONCLUSIONS: This multicenter study shows that the complication rate of central venous catheterization is low and that ultrasound produces a moderate sensitivity and high specificity to detect malposition. There is moderate agreement with chest x-ray film for pneumothorax. In conclusion, ultrasound is an accurate diagnostic modality to detect malposition and pneumothorax.

Short versus long axis ultrasound guided approach for internal jugular vein cannulations: A prospective randomized controlled trial.

OBJECTIVES: Ultrasound-guided internal jugular vein cannulation is a standard procedure performed in ICUs worldwide. According to the guidelines, the short-axis approach is recommended over the long-axis approach for IJV cannulation. Double-operator cannulation is more convenient for the said procedure. However, the guidelines favor single-operator cannulation due to limited trials. We hypothesized that double-operator long-axis cannulation will be faster and have fewer complications than double-operator short-axis cannulation. METHODS: This was a prospective, randomized trial of patients who needed central venous catheterization in the intensive care unit. The eligible patients were randomized into two groups. In one group, the short-axis view by two operators was used for cannulation, and the long-axis view by 2 operators was used in the other group. The time elapsed from skin puncture to guide-wire insertion. RESULTS: The central venous catheter was placed by ultrasound guidance in all 100 patients. No significant differences were observed in the patient characteristics between the two groups. The mean time of insertion was 74.2 ±â€¯110.1 s with the short-axis approach compared with 70.3 ±â€¯97.3 s with the long-axis approach. The frequency of complications was also significantly lower with the long-axis approach. DISCUSSION: The long-axis view for IJV cannulation has similar insertion and procedure timings to the short-axis view. However, the complication rate and number of needle punctures required were less with the long-axis view than with those with the short-axis view.

Tunneled hemodialysis catheter care practices and blood stream infection rate in children: results from the SCOPE collaborative.

OBJECTIVE: The Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) collaborative seeks to reduce hemodialysis (HD) catheter-associated blood stream infections (CA-BSI) by increasing implementation of standardized HD catheter care bundles. We report HD catheter care practices and HD CA-BSI rates from SCOPE. METHODS: Catheter care practices and infection events were collected prospectively during the study period, from collaborative implementation in June 2013 through May 2017. For comparative purposes, historical data, including patient demographics and HD CA-BSI events, were collected from the 12 months prior to implementation. Catheter care bundle compliance in 5 care bundle categories was monitored across the post-implementation reporting period at each center via monthly care observation forms. CA-BSI rates were calculated monthly, and reported as number of infections per 100 patient months. Changes in CA-BSI rates were assessed using generalized linear mixed model (GLMM) techniques. RESULTS: Three hundred twenty-five patients with tunneled HD catheters [median (IQR) age 12 years (6, 16), M 53%, F 47%] at 15 centers were included. A total of 3996 catheter care observations over 4170 patient months were submitted with a median (IQR) 5 (2, 14) observations per patient. Overall bundle compliance was high at 87.6%, with a significant and progressive increase (p < 0.001) in compliance for 4/5 bundle categories over the 48-month study period. The adjusted CA-BSI rate significantly decreased over time from 3.3/100 patient months prior to implementation of the care bundles to 0.8/100 patient months 48 months after care bundle implementation (p < 0.001). CONCLUSIONS: Using quality improvement methodology, SCOPE has demonstrated a significant increase in compliance with a majority of HD catheter care practices and a significant reduction in the rate of CA-BSI among children maintained on HD.

Improved Use of Human Milk, Growth, and Central Line Utilization With Standard Feeding Roadmap in an Academic NICU.

BACKGROUND: Before the initiation of a standardized feeding roadmap in our regional, level IV academic neonatal intensive care unit, utilization of central lines was high, and initiation of enteral feeds delayed in the very low-birth-weight population (<1500 g). Given our review of the literature, it appeared that the standardization of feeding advancement would likely result in improved performance in both issues. METHODS: This was a retrospective cohort comparison of very low-birth-weight patients before initiation of any feeding roadmap with a second cohort following completion of the final roadmap. Infants were examined retrospectively in 2 historical cohorts: Phase 1, infants fed before roadmap development and rollout, October 1, 2012-March 31, 2013; and Phase 2, following promulgation of the final feeding roadmap, January 1, 2017-June 30, 2017. RESULTS: During Phase 2, we observed a significant reduction in median (interquartile range) days to first feed (3 [1] vs 1 [1] [P < 0.0001]) and utilization of a second central line (35% vs 12% [P < 0.01]). Weight gain was significantly improved from before roadmap implementation to final, mean (SD) (g/d, 21 [5] vs 24 [4]; [P < .0001]). Percentage of first enteral feedings that were human milk also increased significantly from 71% to 91% (P = 0.0007). CONCLUSION: Implementation of a standardized feeding roadmap was associated with a reduction in days to first enteral feeds, an increase in the primary use of human milk for initiation of enteral feeds, and a decrease in the utilization of central lines while improving weight gain in very low-birth-weight infants.

Picking the Right Tool for the Job: A Reliability Study of 4 Assessment Tools for Central Venous Catheter Insertion.

BACKGROUND: Determining procedural competence requires psychometrically sound assessment tools. A variety of instruments are available to determine procedural performance for central venous catheter (CVC) insertion, but it is not clear which ones should be used in the context of competency-based medical education. OBJECTIVE: We compared several commonly used instruments to determine which should be preferentially used to assess competence in CVC insertion. METHODS: Junior residents completing their first intensive care unit rotation between July 31, 2006, and March 9, 2007, were video-recorded performing CVC insertion on task trainer mannequins. Between June 1, 2016, and September 30, 2016, 3 experienced raters judged procedural competence on the historical video recordings of resident performance using 4 separate tools, including an itemized checklist, Objective Structured Assessment of Technical Skills (OSATS), a critical error assessment tool, and the Ottawa Surgical Competency Operating Room Evaluation (O-SCORE). Generalizability theory (G-theory) was used to compare the performance characteristics among the tools. A decision study predicted the optimal testing environment using the tools. RESULTS: At the time of the original recording, 127 residents rotated through intensive care units at the University of Calgary, Alberta, Canada. Seventy-seven of them (61%) met inclusion criteria, and 55 of those residents (71%) agreed to participate. Results from the generalizability study (G-study) demonstrated that scores from O-SCORE and OSATS were the most dependable. Dependability could be maintained for O-SCORE and OSATS with 2 raters. CONCLUSIONS: Our results suggest that global rating scales, such as the OSATS or the O-SCORE tools, should be preferentially utilized for assessment of competence in CVC insertion.

OBJECTIVE: To design and validate the content and format of a guidebook for chronic renal failure patients about the care with venous access for hemodialysis at home. METHOD: Methodological study, in which the steps for the guidebook design were: project planning, literature search, material content, and qualification selection. RESULTS: After analysis of the articles, the content to be included in the guidebook was selected. The first draft of the guidebook was submitted for content and format validation, with the participation of 12 specialists. The necessary adjustments for the design of the final version were made with the help of an illustrator. CONCLUSION: The designed guidebook, "Hemodialysis: Care of Venous Accesses and Intercurrences at Home," consists of educational material to help hemodialysis patients with daily care with central venous catheter and arteriovenous fistula practices in case of intercurrences.

Multi-level Intervention Program - A Quality Improvement Initiative to Decrease Central Line-Associated Bloodstream Infections in the Pediatric Acute and Hematology/Oncology Units.

INTRODUCTION: Central Venous Catheters (CVCs) are placed in pediatric patients that require frequent and/or long-term access for intravenous treatments and increase the risk for Central line-associated bloodstream infections (CLABSIs). The specific aims of the study were to evaluate adherence to the intervention components and rates of Central Line Associated Bloodstream Infections (CLABSIs) over five years. METHODS: Implementation occurred on the acute care and hematology-oncology pediatric units of a quaternary health care setting in Southern California. Adherence rates were quantified using a CVC audit sheet and CLABSI rates were obtained quarterly before, and at year 1, 2, 3, 4, 5 of implementation. RESULTS: CLABSI rates for both pediatric units decreased over the five-year period. Adherence rates were 90% to 100% on the different features of the intervention; the lowest was adherence to Patient Protective Equipment (PPE). A total of 41 incidents of hospital-acquired CLABSIs were reported the year prior to the Bug Buster Committee, which decreased steadily to 9 incidents after implementation. The quarterly CLABSI rates in the Pediatric Acute Care ranged from 2.8 to 6.6/1,000 catheter days and in Pediatric Hematology-Oncology from 2.1 to 4.3/1,000 catheter days the year prior to implementation. CONCLUSIONS: While adherence for staff remains high, parent/family adherence was low. We recommend including in the multi-level intervention, procedures targeting parent adherence such as patient education handouts, reviewing content on admission, placing signs on doors indicating PPE requirements, and promptly providing PPE to non-adherent family members.
