Central venous catheters: a survey of ICU practices

Adherence to the central line bundle in intensive care: An integrative review

BACKGROUND

Central line-associated bloodstream infections (CLABSI) occurring in intensive care units are associated with increased morbidity and mortality, increased length of hospitalization, and cost of care associated with treating CLABSIs. The Centers for Disease Control and Prevention guidelines and checklist bundle are intended to provide evidence-based recommendations for the prevention of CLABSIs. Despite the promotion of central line bundle policies, wide variability exists in compliance and infection rates in intensive care units.

OBJECTIVE

To evaluate and synthesize the existing literature on adherence to the central line bundle recommendations for the prevention of CLABSI.

DESIGN

Integrative literature review.

DATA SOURCES

CINHAL, PubMed, and SCOPUS databases were searched.

REVIEW METHODS

Whittmore and Knafl's integrative review method.

RESULTS

A total of 608 articles were identified, 407 articles were screened for topic of interest and adherence to the inclusion criteria, and 19 articles were included in this review. None of the 19 studies addressed adherence to all 14 recommendations of the central line bundle checklist.

CONCLUSION

This integrative review identified gaps in adherence to the central line bundle. Research is needed to determine the actual adherence to each item in the bundle, and to investigate factors that contribute to nonadherence. To achieve complete compliance with all the bundle items creative and innovative technology is needed.

Impact and Safety Associated with Accidental Dislodgement of Vascular Access Devices: A Survey of Professions, Settings, and Devices

Background: Dislodgement rates with intravenous catheters are reported at 1.8%–24% events per year resulting in failed access, interrupted treatment, and greater resource consumption with catheter replacement. The purpose of this study was to quantitatively evaluate the perceptions of frequency, impact, contributing factors, and safety issues from accidental dislodgement affecting intravenous (IV) devices as reported by healthcare clinicians.

Methodology: A cross-sectional descriptive survey was conducted via a voluntary online web-based survey of clinicians. Subjects were divided as those actively working in a clinical healthcare setting and those no longer active. Analysis of data was performed quantifying responses of clinicians on question of dislodgement.

Results: Survey results indicate clinicians routinely observe a significant percentage of accidental dislodgement, with 68% of the 1561 respondents reporting often, daily, or multiple times daily occurrence and 96.5% identifying peripheral intravenous catheters as most common device experiencing accidental dislodgement. Respondents prioritized 10 contributing factors, with confused patient (80%), patient physically removes catheter (74%), and IV catheter tape or securement loose (65%) as the top 3 causes. Over 95% of respondents consider IV dislodgement a safety risk to patients.

Conclusions: This study reports perceptions and impact of accidental dislodgement with IV devices. Inconsistencies exist with use, application, and management of catheter securement and dressings for IV catheters. Risk of additional complications and complete device failure are increased when dislodgement occurs. Given possible complications, along with necessitating replacement of the IV device in many cases, IV catheter dislodgement was considered a safety risk to patients by nearly all respondents.

Knowledge, attitudes, and practice on the prevention of central line-associated bloodstream infections among nurses in oncological care: A cross-sectional study in an area of southern Italy

The objectives of the cross-sectional study were to delineate the knowledge, attitudes, and behavior among nurses regarding the prevention of central line-associated bloodstream infections (CLABSIs) and to identify their predisposing factors. A questionnaire was self-administered from September to November 2011 to nurses in oncology and outpatient chemotherapy units in 16 teaching and non-teaching public and private hospitals in the Campania region (Italy). The questionnaire gathered information on demographic and occupational characteristics; knowledge about evidence-based practices for the prevention of CLABSIs; attitudes towards guidelines, the risk of transmitting infections, and hand-washing when using central venous catheter (CVC); practices about catheter site care; and sources of information. The vast majority of the 335 nurses answered questions correctly about the main recommendations to prevent CLABSIs (use sterile gauze or sterile transparent semipermeable dressing to cover the catheter site, disinfect the needleless connectors before administer medication or fluid, disinfect with hydrogen peroxide the catheter insertion site, and use routinely anticoagulants solutions). Nurses aged 36 to 50 years were less likely to know these main recommendations to prevent CLABSIs, whereas this knowledge was higher in those who have received information about the prevention of these infections from courses. Nurses with lower education and those who do not know two of the main recommendations on the site’s care to prevent the CLABSIs, were more likely to perceive the risk of transmitting an infection. Higher education, attitude toward the utility allow to dry antiseptic, and the need of washing hands before wearing gloves for access to port infusion were predictors of performing skin antiseptic and aseptic technique for dressing the catheter insertion site. Educational interventions should be implemented to address the gaps regarding knowledge and practice regarding the prevention of CLABSIs and to ensure that nurses use evidence-based prevention interventions.

Road map for improvement: Point prevalence audit and survey of central venous access devices in paediatric acute care

AIM

To identify the prevalence, management and complications associated with central venous access devices (CVADs) within Australian paediatric facilities, providing a map for clinicians, researchers and managers to focus solutions.

METHODS

A point prevalence audit and survey of CVAD practices in Australian tertiary paediatric hospitals between September and November 2015, using validated data collection tools.

RESULTS

Across the six sites, 1027 patients were screened with CVADs prevalent in 26.1% (n = 268), and 261 CVADs in 248 patients available for audit. Variations in management were evident with dressings not meeting the basic criteria of clean, dry and intact for 13.5% of CVADs (n = 35), and non-sterile dressings used to reinforce 26.4% of CVADs (n = 69). Almost half of CVADs (49.4%; n = 132) had no documentation regarding site assessment in the previous 4 h, and 13.4% had no planned use in the next 24 h (35 CVAD). CVAD-associated complications within the previous 7 days were evident in 9.5% of CVADs (n = 27), most commonly catheter blockage (5.7% CVAD, n = 15), and bloodstream infection (1.9% CVAD, n = 5). Peripherally inserted central catheters (16.9%) in comparison to other catheter types (7.4%; P = 0.04), and subsequent CVADs (14.1%) in comparison to initial CVADs (6.5%; P = 0.04), had significantly higher proportions of CVAD-associated complications in the previous 7 days. Variation between the sites' guidelines was evident across many practices.

CONCLUSIONS

CVADs are prevalent and essential for paediatric health care; however, complications remain a significant problem. Areas identified for improvement were local CVAD guidelines, regular documentation of CVAD site assessment and review of dressing products to improve integrity.

Central Venous Access Devices Site Care Practices: An International Survey of 34 Countries

Purpose

Effective postinsertion management of central venous access devices (CVADs) is important to prevent CVAD-associated complications, including catheter-associated bloodstream infections. Although there is a wealth of evidence-based guidelines available to guide the care of CVADs, applying their recommendations to the clinical setting across variable patient groups, CVAD types and international healthcare settings is challenging. This may result in patients receiving suboptimal care.

Methods

A cross-sectional descriptive study using an online survey was performed with an aim to determine current CVAD site care practices internationally. The CVAD site care domains included skin antisepsis, dressing selection, frequency of dressing change and device securement practices across impaired and unimpaired CVAD sites.

Results

Clinicians (n = 1044) residing in 34 countries reported diversity in their practice, with the majority of respondents practicing as nurses (89%) from North America (81%) as vascular access specialists (52%). The respondents’ reported practice was variant, with differing inconsistency to guidelines throughout each of the domains. There was wide variance in the management of CVAD sites with impaired skin integrity, such as rash, skin stripping/adhesive-related injuries and drainage. Vascular access clinicians reported high levels of confidence in managing CVAD sites, including those with impaired skin.

Conclusions

These inconsistencies are reflective of the complex and heterogeneous populations requiring CVADs, the evidence available to support practice in this area, the skills and knowledge of the clinicians caring for them and the resources of the healthcare setting. Further research and education is necessary to ensure that CVAD site care is undertaken effectively to minimise preventable complications.

Contributing death factors in very low-birth-weight infants by path method analysis

Background:

Neonatal deaths account for 40% of deaths under the age of 5 years worldwide. Therefore, efforts to achieve the UN Millennium Development Goal 4 of reducing childhood mortality by two-thirds by 2015 are focused on reducing neonatal deaths in high-mortality countries. The aim of present study was to determine death factors among very low-birth-weight infants by path method analysis.

Materials and Methods:

In this study, medical records of 2,135 infants admitted between years 2008 and 2010 in neonatal intense care unit of Alzahra Educational-Medical centre (Tabriz, Iran) were analysed by path method using statistical software SPSS 18.

Results:

Variables such as duration of hospitalisation, birth weight, gestational age have negative effect on infant mortality, and gestational blood pressure has positive direct effect on infant mortality that at whole represented 66.5% of infant mortality variance (F = 1018, P < 0.001). Gestational age termination in the positive form through birth weight, and also gestational blood pressure in negative form through hospitalisation period had indirect effect on infant mortality.

Conclusion:

The results of the study indicated that the duration of low-birth-weight infant's hospitalisation is also associated with infant's mortality (coefficient -0.7; P < 0.001). This study revealed that among the maternal factors only gestational blood pressure was in relationship with infants’ mortality.

PICC-associated bloodstream infections: prevalence, patterns, and predictors

BACKGROUND

Growing use of peripherally inserted central catheters (PICCs) has led to recognition of the risk of PICC-associated bloodstream infection. We sought to identify rates, patterns, and patient, provider, and device characteristics associated with this adverse outcome.

METHODS

A retrospective cohort of consecutive adults who underwent PICC placement from June 2009 to July 2012 was assembled. Using multivariable logistic and Cox-proportional hazards regression models, covariates specified a priori were analyzed for their association with PICC-associated bloodstream infection. Odds ratios (OR) and hazard ratios (HR) with corresponding 95% confidence intervals (CI) were used to express the association between each predictor and the outcome of interest.

RESULTS

During the study period, 966 PICCs were inserted in 747 unique patients for a total of 26,887 catheter days. Indications for PICC insertion included: long-term antibiotic administration (52%, n = 503), venous access (21%, n = 201), total parenteral nutrition (16%, n = 155), and chemotherapy (11%, n = 107). On bivariate analysis, intensive care unit (ICU) status (OR 3.23; 95% CI, 1.84-5.65), mechanical ventilation (OR 4.39; 95% CI, 2.46-7.82), length of stay (hospital, OR 1.04; 95% CI, 1.02-1.06 and ICU, OR 1.03; 95% CI, 1.02-1.04), PowerPICCs (C. R. Bard, Inc., Murray Hill, NJ; OR 2.58; 95% CI, 1.41-4.73), and devices placed by interventional radiology (OR 2.57; 95% CI, 1.41-4.68) were associated with PICC-bloodstream infection. Catheter lumens were strongly associated with this event (double lumen, OR 5.21; 95% CI, 2.46-11.04, and triple lumen, OR 10.84; 95% CI, 4.38-26.82). On multivariable analysis, only hospital length of stay, ICU status, and number of PICC lumens remained significantly associated with PICC bloodstream infection. Notably, the HR for PICC lumens increased substantially, suggesting earlier time to infection among patients with multi-lumen PICCs (HR 4.08; 95% CI, 1.51-11.02 and HR 8.52; 95% CI, 2.55-28.49 for double- and triple-lumen devices, respectively).

CONCLUSIONS

PICC-associated bloodstream infection is most associated with hospital length of stay, ICU status, and number of device lumens. Policy and procedural oversights targeting these factors may be necessary to reduce the risk of this adverse outcome.

Prevention of central venous catheter infections: a survey of paediatric ICU nurses' knowledge and practice

BACKGROUND

Central venous catheters are important in the management of paediatric intensive care unit patients, but can have serious complications which worsen the patients' health, prolong hospital stays and increase the cost of care. Evidence-based recommendations for preventing catheter-related bloodstream infections are available, but it is unknown how widely these are known or practiced in the paediatric intensive care environment.

OBJECTIVES

To assess nursing knowledge of evidence based guidelines to prevent catheter-related bloodstream infections; the extent to which Australia and New Zealand paediatric intensive cares have adopted prevention practices; and to identify the factors that encouraged their adoption and improve nursing knowledge.

DESIGN

Cross-sectional surveys using convenience sampling.

SETTINGS

Tertiary level paediatric intensive care units in Australia and New Zealand.

PARTICIPANTS

Paediatric intensive care nursing staff and nurse managers.

METHODS

Between 2010 and 2011, the 'Paediatric Intensive Care Nurses' Knowledge of Evidence-Based Catheter-Related Bloodstream Infection Prevention Questionnaire' was distributed to paediatric intensive care nursing staff and the 'Catheter-Related Bloodstream Infection Prevention Practices Survey' was distributed to nurse managers to measure knowledge, practices and culture.

RESULTS

The questionnaires were completed by 253 paediatric intensive care nurses (response rate: 34%). The mean total knowledge score was 5.5 (SD=1.4) out of a possible ten, with significant variation of total scores between paediatric intensive care sites (p=0.01). Other demographic characteristics were not significantly associated with variation in total knowledge scores. All nursing managers from Australian and New Zealand paediatric intensive care units participated in the survey (n=8; response rate: 100%). Wide practice variation was reported, with inconsistent adherence to recommendations. Safety culture was not significantly associated with mean knowledge scores per site.

CONCLUSIONS

This study has identified that there is variation in the infection prevention approach and nurses' knowledge about catheter-related bloodstream infection prevention. The presence of an improved safety culture, years of paediatric intensive care experience and higher qualifications did not influence the nurses' uptake of recommendations, therefore further factors need to be explored in order to improve understanding and implementation of best practice.

A survey of central venous catheter practices in Australian and New Zealand tertiary neonatal units

BACKGROUND

Infection is the most common problem with central venous catheters (CVCs) in neonates. There are two published guidelines, including the Centers for Disease Control and Prevention (CDC), for the prevention of intravascular catheter-related infection that describes evidence-based practice to reduce nosocomial infection.

OBJECTIVE

Our aims were to survey current medical and nursing management of central venous catheters in tertiary neonatal intensive care units in Australia and New Zealand and to compare with the CDC evidence-based practice guideline.

METHODS

A cross sectional survey was performed across 27 Australian and New Zealand neonatal units in September 2012. Two web-based questionnaires were distributed, one to medical directors related to the insertion of CVCs while CVC "maintenance" surveys were sent to nurse unit managers.

RESULTS

Seventy percent (19/27) medical management and 59% (16/27) on nursing management surveys were completed. In all neonatal intensive care units (NICUs) there were guidelines for CVC maintenance and for 18 out of 19 there were guidelines for insertion. In the seven units using femoral lines, three had a guideline on insertion and four for maintenance. CVC insertion was restricted to credentialed staff in 57.9% of neonatal units. Only 26.5% used full maximal sterile barriers for insertion. Skin disinfection practices widely varied. Dressing use and dressing change regimens were standardised; all using a semi-permeable dressing. Duration of cleaning time of the access point varied significantly; however, the majority used a chlorhexidine with alcohol solution (68.8%). Line and fluid changes varied from daily to 96 h. The majority used sterile gloves and a sterile dressing pack to access the CVC (68.8%). In the majority of NICUs stopcocks were used (62.5%) with a needle-less access point attached (87.5%). In less than 50% of NICUs education was provided on insertion and maintenance.

CONCLUSION

There is diversity of current practices and some aspects vary from the CDC guideline. There is a need to review NICU current practices to align with evidence based guidelines. The introduction of a common guideline may reduce variations in practice.

Reducing the risk of infection associated with vascular access devices through nanotechnology: a perspective

Intravascular catheter-related infections are still a major problem in health care and are associated with significant morbidity, mortality, and additional cost. The formation of microbial biofilm on catheters makes these infections particularly complicated, as microbial cells that detach from the biofilm can lead to infection, and because these microorganisms are highly resistant to many antimicrobial agents; thus, catheter removal is often required to successfully treat infection. To reduce the risks of catheter-related infections, many strategies have been applied, such as improvements in aseptic insertion and post-insertion care practices, implantation techniques, and antibiotic coated or impregnated materials. However, despite significant advances in using these methods, it has not been possible to completely eradicate biofilm infections. Currently, nanotechnology approaches seem to be among the most promising for preventing biofilm formation and resultant catheter-related bloodstream infection (especially with multi-resistant bacterial strains). In this review, current knowledge about catheter technology and design, the mechanisms of catheter-related bloodstream infection, and the insertion and care practices performed by medical staff, are discussed, along with novel, achievable approaches to infection prevention, based on nanotechnology.

The reduction of risk in central line-associated bloodstream infections: knowledge, attitudes, and evidence-based practices in health care workers

BACKGROUND

We set out to acquire information about the knowledge, attitudes, and evidence-based practices associated with the insertion and maintenance of central vascular catheters (CVC) for the prevention of central line-associated bloodstream infections (CLABSI).

METHODS

We selected all health care workers (HCW) in all units using CVCs in the Calabria region of Italy.

RESULTS

Correct answers about the knowledge of physicians and nurses ranged from 43% to 72.9% and were significantly higher in respondents who worked in intensive care unit (ICU) wards in hospitals that had a written policy about CVC maintenance and had active formal training. Respondents' attitudes toward general aspects of CLABSI prevention were very positive and were significantly higher for HCWs working in regional general hospitals, practicing in ICU wards, and having appropriate knowledge. Concerning HCWs, 83.9% reported that, if patients had any manifestations suggesting local or bloodstream infection, the dressing was removed for assessment purposes; this practice was significantly more likely to occur in HCWs having appropriate knowledge and positive attitudes and who worked in hospitals with a written policy about CVC maintenance.

CONCLUSION

The study demonstrated that written policies, formal training, and years of experience contributed to an increase in knowledge, practice, and positive attitudes toward CLABSI prevention. In addition the paper demonstrates how great this need is, having reported many non-evidence-based practices still continuing despite new evidence.

RN Knowledge of Vascular Access Devices Management

Purpose: To explore the level of RNs knowledge of managing vascular access devices (VADs)- peripherally inserted central catheters (PICCs) and midline catheters, and to determine if nurse characteristics are associated with knowledge level.

Background: Education of nursing staff about VAD management can improve quality of care and assure standards of practice are maintained.

Review of Literature: Minimal research is available on nurses' knowledge of managing VAD catheters.

Methods: Nurses working on a colo-rectal unit who frequently manage VADs in a large tertiary-care medical center voluntarily completed one anonymous, validated, 10-item survey of VAD management themes. Analysis included descriptive and correlational statistics.

Results: Of 36 nurses, (97% female, 53% full time), mean VAD knowledge score was 8.1 ± 1.4 (81% mean sum score). Perceived general level of comfort in flushing PICCs (r=.35, P=0.04), using Alteplase with PICCs (r=.36, P=0.03) and changing dressings (r=.38; P=0.03) were associated with higher knowledge scores. Of 10 items, 4 resulted in scores below 80%: how fast a Midline can be used after insertion, first step in managing a PICC upon admission, steps in dealing with a withdrawal occlusion, and steps post interventional radiology PICC insertion; however, nurse characteristics were not associated with scores above or below 80%.

Conclusions: Nurses working in the colo-rectal unit that frequently treat patients with VADs were generally knowledgeable about their management. Perceived nurse comfort in flushing a PICC, using Alteplase, and changing dressings were associated with higher knowledge.

Implications for Practice: Nurses' impressions of comfort with VAD management should be regularly assessed by nurse managers to assure optimal knowledge.

A broad-spectrum look at catheter-related bloodstream infections: many aspects, many populations

The issue of central vascular catheter-related bloodstream infections is prominent in medical literature and practice today, both in the United States and throughout the international healthcare community. In its 2002 report on Guidelines for the Prevention of Intravascular Catheter-Related Infections, the Centers for Disease Control and Prevention estimated that 250,000 cases of central vascular catheter-related infections occur annually. This article is a review of current literature pertaining to catheter-related bloodstream infections. Included are resources from 2004 onward, as well as resources such as the Centers for Disease Control and Prevention, the Institute for Healthcare Improvement, and the National Guideline Clearinghouse.

Pro/con debate: do the benefits of regionalized critical care delivery outweigh the risks of interfacility patient transport?

You are providing input in planning for critical care services to a large regional health authority. You are considering concentrating some critical care services into high-volume regional centres of excellence, as has been done in other fields of medicine. In your region, this would require several centres with differing levels of expertise that are geographically separated. Given there are inherent risks and time delays associated with interfacility patient transport, you debate whether these potential risks outweigh the benefits of regional centres of excellence.

[Intensive care nurses' knowledge about the evidence-based guidelines of preventing central venous catheter related infection]

OBJECTIVES

To determine intensive care unit (ICU) nurses' knowledge of evidence-based guidelines for preventing central venous catheter (CVC) related infection.

METHOD

We used a validated multiple-choice questionnaire which was distributed to intensive care units between October and December 2006. We collected demographic data, like gender, years of ICU experience, number of ICU beds and whether respondents hold a special degree in intensive care.

RESULTS

We collected 178 questionnaires from 11 intensive care units; the mean score was 3.66 on 10 questions (37%). Eighteen per cent knew that CVCs should be replaced on indication only, and 61% knew that this recommendation concerns also replacement over a guidewire. Recommendations for replacing pressure transducers and tubing every 4 days, and for using coated devices in patients requiring a CVC < 5 days in settings with high infection rates were recognized only by 48% and 66%, respectively. Regarding CVC dressings, 15% knew that these should be changed only when indicated and at least once weekly, and 35% recognized that both poly-urethane and gauze dressings can be recommended. Only 20% checked 2% aqueous chlorhexidine as recommended disinfection solution; 14% knew antibiotic ointments are not recommended because they trigger resistance. The recommendation to replace administration sets within 24 hours after administering lipid emulsions was recognized by 85%, but it was known by 5% only that these sets should be replaced every 96 hours when administering neither lipid emulsions nor blood products. Professional seniority and the number of intensive care beds in the ICU where nurses work showed not to be associated with better scores on the test.

DISCUSSION

Knowledge regarding CVC-related infection is poor among Hungarian nurses. Prevention guidelines should be included in the nurse education curriculum as well as in continuing refresher nursing education programs.

Tiny patients, tiny dressings: a guide to the neonatal PICC dressing change

Advances in neonatology now support the survival of the tiniest of infants. The peripherally inserted central catheter (PICC) has now become an integral part of routine practice in neonatal intensive care units around the world. Keen attention to safe maintenance of these devices is essential. A properly applied and maintained PICC dressing is the first line of defense to minimize the risk of complications such as dislodgement, migration, and infection. This article describes a neonatal PICC dressing change and discusses the frequently encountered quandaries surrounding this important procedure, including dressing materials, frequency, site preparation, barrier precautions, and other relevant concerns.

O cuidado de enfermagem e o cateter de Hickman: a busca de evidências

INTRODUÇÃO: Os pacientes submetidos ao transplante de medula óssea (TMO) necessitam de um acesso venoso seguro para a infusão da medula óssea. A implantação de um cateter venoso central é parte da terapêutica, sendo o de Hickman o mais utilizado atualmente; entretanto, sua presença impõe riscos, sendo a infecção, o mais preocupante. OBJETIVO: Revisão integrativa da literatura, que teve como objetivo buscar e avaliar as evidências sobre os cuidados de enfermagem relacionados ao cateter de Hickman. MÉTODO: Para a seleção dos artigos utilizamos as bases de dados Lilacs, Medline, Cinahl e o periódico Bone Marrow Transplantation, e a amostra constituiu-se de 18 artigos. RESULTADOS: O curativo recomendado é o de poliuretano trocado a cada 7 dias. O método de coleta de sangue observado foi o de descarte, sendo que a dosagem de ciclosporina não deve ser coletada da mesma via onde foi infundida. A redução do número de manipulações do cateter é considerada uma medida eficaz na prevenção e no controle de infecção. CONSIDERAÇÕES FINAIS: As evidências extraídas dos estudos analisados podem auxiliar a implementação de cuidados de enfermagem eficazes relacionados ao cateter de Hickman.
