Determinants of the optimal selection of vascular access devices: A systematic review underpinned by the COM-B behavioural model.

BACKGROUND: Optimal selection of vascular access devices is based on multiple factors and is the first strategy to reduce vascular access device-related complications. This process is dependent on behavioural and human factors. The COM-B (Capability, Opportunity, Motivation, Behaviour) model was used as a theoretical framework to organize the findings of this systematic review. METHODS/AIMS: To synthesize the evidence on determinants shaping the optimal selection of vascular access devices, using the COM-B behavioural model as the theoretical framework. DESIGN: Systematic review of studies which explore decision-making at the time of selecting vascular access devices. DATA SOURCES: The Medline, Web of Science, Scopus and EbscoHost databases were interrogated to extract manuscripts published up to 31 December 2021, in English or Spanish. RESULTS: Among 16 studies included in the review, 8/16 (50%) focused on physical capability, 8/16 (50%) psychological capability, 15/16 (94%) physical opportunity, 12/16 (75%) social opportunity, 1/16 (6%) reflective motivation and 0/16 (0%) automatic motivation. This distribution represents a large gap in terms of interpersonal and motivational influences and cultural and social environments. Specialist teams (teams created for the insertion or maintenance of vascular access devices) are core for the optimal selection of vascular access devices (75% physical capability, 62% psychological capability, 80% physical opportunity and 100% social opportunity). CONCLUSION: Specialist teams predominantly lead all actions undertaken towards the optimal selection of vascular access devices. These actions primarily centre on assessing opportunity and capability, often overlooking motivational influences and social environments. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: A more implementation-focused professional approach could decrease inequity among patients and complications associated with vascular access devices. IMPACT: Optimal selection of vascular access devices is the primary strategy in mitigating complications associated with these devices. There is a significant disparity between interpersonal and motivational influences and the cultural and social environments. Furthermore, specialized teams play a pivotal role in facilitating the optimal selection of vascular access devices. The study can benefit institutions concerned about vascular access devices and their complications. REPORTING METHOD: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution. WHAT DOES THIS ARTICLE CONTRIBUTE TO THE WIDER GLOBAL CLINICAL COMMUNITY?: Optimal selection of vascular devices remains a growing yet unresolved issue with costly clinical and patient experience impact. Interventions to improve the optimal selection of vascular devices have focused on training, education, algorithms and implementation of specialist vascular teams; alas, these approaches do not seem to have substantially addressed the problem. Specialist vascular teams should evolve and pivot towards leading the implementation of quality improvement interventions, optimizing resource use and enhancing their role.

Definition and clinical management of haemodialysis central venous catheter local infections (exit site and tunnel infection): An international consensus assessment.

AIM: To evaluate the relevance of signs and symptoms for the clinical identification of ESI and TI in HD-CVC, by means of international expert consensus, and to reach a consensus on a definition and clinical management (CM) for these infections. BACKGROUND: A recent systematic review showed a high heterogeneity in the signs/symptoms used for determining exit site infection (ESI) and tunnel infection (TI) of haemodialysis central venous catheter (HD-CVC). DESIGN: A modified Delphi ranking process was carried out between November 2020 and March 2021, consisting of four rounds using an online questionnaire with a panel of 26 experts from 12 countries. METHODS: Experts responded on the level of relevance for the identification of ESI and TI, based on a list of 22 signs/symptoms obtained from a previous systematic review, using a 4-point Likert-type scale. After reaching consensus on the signs/symptoms, they followed the same method to reach consensus on the CM. The STROBE Checklist was used to report this study. RESULTS: A high degree of consensus was reached to identify the presence of ESI based on nine signs/symptoms: presence of pain at the exit site (ES) during interdialysis period, with fever ≥38°C do not suspect other cause, local signs at the ES (inflammation, induration, swelling, hyperemia/erythema ≥2 cm from ES) and obvious abscess or purulent exudate at ES; and of TI. Likewise, 5 cm were agreed upon. CONCLUSION: This Delphi study provides international expert consensus definitions of ESI and TI in HD-CVC, laying the groundwork for the validation of an HD-CVC ES clinical assessment scale for early identification of ESI. RELEVANCE TO CLINICAL PRACTICE: In addition, this study provides a series of attitudes to consensual clinics regarding signs/symptoms of local infections in HD-CVC, which may be useful as expert opinion in clinical practice guidelines, when there is insufficient scientific evidence.

Interventions to reduce peripheral intravenous catheter failure: An international e-Delphi consensus on relevance and feasibility of implementation.

BACKGROUND: Around 1 billion peripheral intravenous catheters (PIVC) fail annually worldwide before prescribed intravenous therapy is completed, resulting in avoidable complications, dissatisfaction, and avoidable costs surging to ∼€4bn. We aimed to provide an international consensus on relevance and feasibility of clinical practice guideline recommendations to reduce PIVC failure. METHODS: e-Delphi study with three rounds through an online questionnaire from March-September 2020 recruiting a multispecialty panel formed by clinicians, managers, academic researchers, and experts in implementation from seven developed and three developing countries, reflecting on experience in PIVC care and implementation of evidence. Further, we included a panel of chronic patients with previous experience in the insert, maintenance, and management of PIVC and intravenous therapy from Ireland and Spain as public and patient involvement (PPI) panel. All experts and patients scored each item on a 4-point Likert scale to assess the relevance and feasibility. We considered consensus descriptor in which the median was 4 with less than or equal to 1,5 interquartile intervals. FINDINGS: Over 90% participants (16 experts) completed the questionnaire on all rounds and 100% PPI (5 patients) completed round 1 due to high consensus they achieved. Our Delphi approach included 49 descriptors, which resulted in an agreed 30 across six domains emerged from the related to (i) general asepsis and cutaneous antisepsis (n = 4), (ii) catheter adequacy and insertion (n = 3), (iii) catheter and catheter site care (n = 6), (iv) catheter removal and replacement strategies (n = 4), (v) general principles for catheter management (n = 10), and (vi) organisational environment (n = 3). CONCLUSION: We provide an international consensus of relevant recommendations for PIVC, deemed feasible to implement in clinical settings. In addition, this methodological approach included substantial representation from clinical experts, academic experts, patient and public expertise, mitigating uncertainty during the implementation process with high-value recommendations to prevent PIVC failure based contextual and individual features, and economic resources worldwide.

Analysis of palliative care needs in hospitalized patients.

AIM: To determine the prevalence of palliative care needs in patients in an acute care hospital and to analyze the profile of these patients. DESIGN: We conducted a prospective cross-sectional study in an acute care hospital, in April 2018. The study population consisted of all patients over 18 years of age admitted to hospital wards and intensive care units. Variables were collected on a single day by six micro-teams using the NECPAL CCOMS-ICO© instrument. The descriptive analysis, on patient mortality and length of stay, was performed at a one-month follow-up. RESULTS: We assessed 153 patients, of whom 65 (42.5%) were female, with a mean age of 68.17±17.03 years. A total of 45 patients (29.4%) were found to be SQ+, of which 42 were NECPAL+ (27.5%), with a mean age of 76.64±12.70 years. According to the disease indicators, 33.35% had cancer, 28.6% had heart disease, and 19% had COPD, resulting in a ratio of 1:3 between patients with cancer and non-cancer disease. Half of the inpatients in need of palliative care were in the Internal Medicine Unit. CONCLUSIONS: Almost 28% of patients were identified as NECPAL+, most of them not identified as under palliative care in clinical records. Greater awareness and knowledge from healthcare professionals would facilitate the early identification of these patients and avoid overlooking palliative care needs.

Early identification of local infections in central venous catheters for hemodialysis: A systematic review.

BACKGROUND: The use of central venous catheters (CVC) is associated with higher morbidity and mortality, related to infectious complications, contributing to poorer clinical outcomes and increased healthcare costs. According to the literature, the incidence of local infections related to CVC for hemodialysis is highly variable. This variability is related to differences in definitions of catheter-related infections. OBJECTIVE: To identify signs and symptoms for determining local infections (exit site and tunnel tract infections) used in the literature in tunnelled and nontunnelled CVC for hemodialysis. DESIGN: Systematic review METHODS: Structured electronic searches were conducted in five electronic databases, from 1 January 2000-31 August 2022, using key words and specific vocabulary, as well as manual searches in several journals. Additionally, vascular access clinical guidelines and infection control clinical guidelines were reviewed. RESULTS: After validity analysis, we selected 40 studies and seven clinical guidelines. The definitions of exit site infection and tunnel infection used in the different studies were heterogeneous. Among the studies, seven (17,5 %) used the definitions of exit site and tunnel infection based on a clinical practice guideline. Three of the studies (7.5 %) used the Twardowski scale definition of exit site infection or a modification. The remaining 30 studies (75 %) used different combinations of signs and symptoms. CONCLUSIONS: Definitions of local CVC infections are highly heterogeneous in the revised literature. It is necessary to establish a consensus regarding the definitions of hemodialysis CVC exit site and tunnel infections. REGISTRATION: PROSPERO (CRD42022351097).

Impact of advanced practice nurses in hospital units on compliance with clinical practice guidelines: a quasi-experimental study.

BACKGROUND: Incorporating the best available evidence into clinical practice is a determining challenge for healthcare professionals and organisations. The role of advanced practice nurses is viewed as a facilitator to adapt guideline recommendations to suit specific contexts and to overcome barriers to implementation. In this study, we evaluate the impact of advanced practice nurses on clinical indicators of hospitalised patients and on adherence to recommendations derived from two clinical practice guidelines (pressure ulcer prevention and treatment and vascular access device management). METHODS: Quasi-experimental study in five intervention (IU) and five control (CU) hospital units at three hospitals in Spain (period 2018-19). Five advanced practice nurses were incorporated into IU, with the intention that would produce attitudinal changes and enhance the skills and knowledge of the nursing team regarding 18 clinical practice recommendations. In this study, 41 indicators were evaluated through direct observation of all patients admitted, at monthly intervals for 1 year. Outcomes were assessed by means of a descriptive, multi-line regression and association analysis. RESULTS: The study population was composed of 3742 inpatients admitted for pressure ulcer assessment and 2631 fitted with vascular access devices. By the end of the study period, all variables had improved in the IU, where average compliance with recommendations was statistically significantly higher (pressure ulcer guidance 7.9 ± 1.9 vs 6.0 ± 1.7. OR 1.86, 95% CI 1.67-2.05; vascular access devices guidance 5.4 ± 1.4 vs 4.4 ± 1,6. OR 1.06, 95% CI 0.95-1.17). The prevalence of pressure lesions and catheter-related adverse events decreased statistically significantly in the IU compared to the CU. The prevalence of pressure ulcers decreases (5.7% in IU vs 8.7% in CU p < 0.005) as well as the prevalence of adverse events related to the catheter (14% In IU vs 21.6% in CU p < 0.005). The unnecessary catheters decressed in IU 10.9% VS CU 15.8% (p < 0.005). CONCLUSIONS: The incorporation of an advanced practice nurse statistically significantly improves clinical indicators related to the prevention and treatment of pressure ulcers and to the management of vascular access devices.

What fuels suboptimal care of peripheral intravenous catheter-related infections in hospitals? A qualitative study of decision-making among Spanish nurses.

BACKGROUND: Peripheral intravenous catheters (PIVC) are commonly used in hospital worldwide. However, PIVC are not exempt from complications. Catheter-related bloodstream infections (CRBSI) increase morbidity and mortality rates, and costs for the healthcare organization. PIVC care is shaped by the complex mix of professional and organizational culture, such as knowledge gaps, low perception of impact of PIVCs on patient safety, or lack of hospital guidelines. AIM: To explore determinants of decision-making about the prevention of PIVC-BSI among nurses in Spanish hospitals. METHODS: We conducted a descriptive qualitative study with semi-structured interviews in three public hospitals, the Balearic Islands Health Care Service in Spain. We considered hospital ward nurses working routinely with inpatients at any of the three hospitals for enrolment in the study. We approached relevant informants to identify suitable participants who recruited other participants through a 'snowball' technique. Fourteen inpatient nurses from the hospital took part in this study between September and November 2018. We employed several triangulation strategies to underpin the methodological rigour of our analysis and conducted the member checking, showing the information and codes applied in the recording of the interviews to identify the coherence and any discrepancies of the discourse by participants. We used the COREQ checklist for this study. FINDINGS: We identified four major themes in the analysis related to determinants of care: The fog of decision-making in PIVC; The taskification of PIVC care; PIVC care is accepted to be suboptimal, yet irrelevant; and chasms between perceived determinants of poor PIVC care and its solutions. CONCLUSION: The clinical management of PIVCs appear ambiguous, unclear, and fragmented, with no clear professional responsibility and no nurse leadership, causing a gap in preventing infections. Furthermore, the perception of low risk on PIVC care impact can cause a relevant lack of adherence to the best evidence and patient safety. Implementing facilitation strategies could improve the fidelity of the best available evidence regarding PIVC care and raise awareness among nurses of impact that excellence of care.

Validity of a catheter exit site clinical assessment scale for the early detection of exit site infections in patients on haemodialysis with a central venous catheter: protocol for a multicentre validation study in Spain (EXITA Study).

INTRODUCTION: Haemodialysis patients with central venous catheter (HD-CVC) are at increased risk of exit site infections (ESIs) and catheter-related bloodstream infections, causing an increase of hospitalisation, morbidity and mortality rates. The main aim of the EXITA Study is to develop and validate an instrument for the early detection of HD-CVC ESIs. METHODS AND ANALYSIS: EXITA is a multicentre prospective cohort study to validate the proposed instrument with a sample of 457 HD-CVCs: 92 in the ESI group and 365 in the non-ESI group. Sample size was calculated using Epidat V.4.2 software, with 95% and 90% expected sensitivity and specificity, respectively, an ESI incidence around 20% and 5%-10% precision range. During each haemodialysis session, the absence or presence of each item will be assessed by nurses. If any item is present, a microbiological study of pericatheter skin smears and/or exit site exudate will be carried out. HD-CVC ESI will be diagnosed when the pericatheter skin smears and/or exit site exudate culture are positive (≥15 CFU/mL by semiquantitative Maki's technique or ≥1000 CFU/mL by Cleri's technique). To validate the scale, a logistic regression analysis will be performed: the ß coefficients of each of the signs/symptoms of the scale to be validated will be estimated. We will use logit function and calculate ESI probability=elogit ESI/1+elogit ESI. ETHICS AND DISSEMINATION: The study has been approved by the Research Ethics Committee with Medical Products of Cantabria (approval code 2019.146). We will obtain informed consent from all participants before data collection. We will publish the study results in a peer-reviewed scientific journal.

Multimodal intervention for preventing peripheral intravenous catheter failure in adults (PREBACP): a multicentre, cluster-randomised, controlled trial.

BACKGROUND: 2 billion peripheral intravenous catheters (PIVC) are inserted into inpatients worldwide each year. Almost one in two PIVCs fail before completion of intravenous therapy. We aimed to determine the efficacy and costs of a multimodal intervention to reduce PIVC failure among hospitalised patients. METHODS: PREBACP was a cluster-randomised, controlled trial done at seven public hospitals in Spain. Clusters (hospital wards) had at least 70% permanent staff and data were collected from patients aged 18 years and older with one or more PIVCs at the start of intravenous therapy. Clusters were randomly assigned (1:1) to the multimodal intervention or control group using a centralised, web-based randomisation software, and stratified by type of setting. We concealed randomisation to allocation, without masking patients or professionals to the intervention. An intervention using a multimodal model and dissemination of protocols, education for health-care professionals and patients, and feedback on performance was implemented for 12 months in the intervention group. The control group received usual care. The primary outcome was all-cause PIVC failure at 12 months (phlebitis, extravasation, obstruction, or infections). Subsequently, through an amendment to the protocol approved on July 25, 2021, we included dislodgement as part of PIVC failure. Analysis was by modified intention to treat, which included all randomly assigned hospital wards for whom data on the primary endpoint were available. This trial is registered with the ISRCTN Registry, ISRCTN10438530. FINDINGS: Between Jan 1, 2019, and March 1, 2020, we randomly assigned 22 eligible clusters to receive the multimodal intervention (n=11 clusters; 2196 patients, 2235 PIVCs, and 131 nurses) or usual practice in the control group (n=11 clusters; 2282 patients, 2330 PIVCs, and 138 nurses). At 12 months, the proportion of PIVC failures was lower in the intervention group than in the control group (37·10% [SD 1·32], HR 0·81 [95% CI 0·72 to 0·92] vs 46·49% [2·59], HR 1·23 [1·04 to 1·39]; mean difference -9·39% [95% CI -11·22 to -7·57]; p<0·0001). Per-protocol-prespecified analysis of the primary outcome excluding dislodgement also showed the intervention significantly reduced PIVC failure compared with the control group at 12 months (33·47% [SD 2·98], HR 0·85 [95% CI 0·75 to 0·96] vs 41·06% [4·62], HR 1·18 [1·04 to 1·33]; mean difference -7·59% [95% CI -11·05 to -4·13]; p<0·0001). INTERPRETATION: A multimodal intervention reduced PIVC failure, thereby reducing potentially serious complications for hospitalised patients. The findings of PREBACP enabled a deeper understanding of decision making, knowledge mobilisation, and sense making in routine clinical practice.

Care of peripheral intravenous catheters in three hospitals in Spain: Mapping clinical outcomes and implementation of clinical practice guidelines.

BACKGROUND: Peripheral intravenous catheters (PIVCs) are the most widely used invasive devices worldwide. Up to 42% of PIVCs are prematurely removed during intravenous therapy due to failure. To date, there have been few systematic attempts in European hospitals to measure adherence to recommendations to mitigate PIVC failures. AIM: To analyse the clinical outcomes from clinical practice guideline recommendations for PIVC care on different hospital types and environments. METHODS: We conducted an observational study in three hospitals in Spain from December 2017 to April 2018. The adherence to recommendations was monitored via visual inspection in situ evaluations of all PIVCs inserted in adults admitted. Context and clinical characteristics were collected by an evaluation tool, analysing data descriptively. RESULTS: 646 PIVCs inserted in 624 patients were monitored, which only 52.7% knew about their PIVC. Regarding PIVC insertion, 3.4% (22/646) patients had at least 2 PIVCs simultaneously. The majority of PIVCs were 20G (319/646; 49.4%) and were secured with transparent polyurethane dressing (605/646; 93.7%). Most PIVCs (357/646; 55.3%) had a free insertion site during the visual inspection at first sight. We identified 342/646 (53%) transparent dressings in optimal conditions (clean, dry, and intact dressing). PIVC dressings in medical wards were much more likely to be in intact conditions than those in surgical wards (234/399, 58.7% vs. 108/247, 43.7%). We identified 55/646 (8.5%) PIVCs without infusion in the last 24 hours and 58/646 (9.0%) PIVCs without infusion for more than 24 hours. Regarding PIVC failure, 74 (11.5%) adverse events were identified, all of them reflecting clinical manifestation of phlebitis. CONCLUSIONS: Our findings indicate that the clinical outcome indicators from CPG for PIVC care were moderate, highlighting differences between hospital environments and types. Also, we observed that nearly 50% of patients did not know what a PIVC is.

Moving Evidence into Practice by Advanced Practice Nurses in Hospitalization Wards. Protocol for a Multicentre Quasi-Experimental Study in Three Hospitals in Spain.

Evidence-based practice (EBP) combined with quality of care improves patient outcomes. However, there are still difficulties for its implementation in daily clinical practice. This project aims to evaluate the impact of the incorporation of the Advanced Practice Nurse (APN) role on the implementation of EBP at three levels: context, nurses' perceptions, and clinical outcomes. Mixed-methods study in two phases is proposed. Phase 1: a quasi-experimental design where five APNs are included in five hospitalization wards that are compared with another five similar wards without APNs. Variables from Practice-Environment-Scale-Nursing-Work-Index, Health-Science-Evidence-Based-Practice-Questionnaire, and Advanced-Practice-Nursing-Competency-Assessment-Instrument are used. Clinical outcomes are followed-up with monthly. A descriptive and exploratory analysis is performed. Phase 2: an exploratory qualitative design through focus groups at the intervention wards after one year of APNs implementation. Explicative data are gathered to explain the progression of change and how actors perceive and attribute triggers, barriers, and facilitators for change. An inductive thematic analysis is performed. The inclusion of APN in hospitalization context is insufficiently studied. It is hoped that these figures provide solutions to the multiple barriers in the development of EBP in these sceneries and contribute to resolve the gap between research results and healthcare practice.

Risk Factors for Difficult Peripheral Intravenous Cannulation. The PIVV2 Multicentre Case-Control Study.

BACKGROUND: Difficult peripheral intravenous cannulation (DPIVC) is associated with serious complications related to vascular access. These complications might be avoided if the risk factors were identified previously, enabling the detection of potentially difficult situations at an early stage. The aim of this study is to consider these risk factors, to determine the influence of the hospital setting, to examine the association between DPIVC and the different techniques of catheter insertion and to analyse the importance of the clinician's experience in this context. METHODS: Case-control study following a previously published protocol, conducted in 48 units of eight public hospitals in Spain. Adult patients requiring a peripheral intravenous cannula were prospectively included in the study population during their hospital stay. Over a period of 11 months, for consecutive eligible patients, nurses in each participating unit recorded data on their assessment of the vascular access performed and the technique used. Variables related to these medical personnel were also recorded. One of the researchers reviewed the patients' clinical history to compile the relevant health variables and to characterise the healthcare process. The statistical analysis included association tests among the main study variables. The risk factors were analysed using bivariate logistic regression. The variables found to be statistically significant were included in a multivariate logistic regression model incorporating each of the healthcare environments identified. RESULTS: The study population was composed of 2662 patients, of whom 221 (8.3%) presented with DPIVC. A previous history of difficulty, the presence of non-palpable veins, acute upper limb alterations and punctures in the ante-cubital fossa were found to be independent risk factors for DPIVC. Differences were found in the frequency of occurrence of DPIVC and in some risk factors, according to the healthcare context. The variables related to the characteristics of the hospital personnel did not influence the study event. CONCLUSION: The present study identifies four independent risk factors for DPIVC that can be incorporated into algorithms aimed at preventing its occurrence and facilitating the referral of patients to vascular access specialist teams.

Defining risk factors associated with difficult peripheral venous Cannulation: A systematic review and meta-analysis.

Peripheral venous catheterization is a common technique in hospitals which is not always successful, resulting in multiple punctures and degradation of the vessels. This scenario, which we have termed 'difficult peripheral venous access', is associated to delays in care, obtention of samples or diagnosis, as well as a higher use of central catheters. This study intends to identify risk factors associated to the incidence of 'difficult peripheral venous access' in adults at hospital. We designed a systematic review of published studies (protocol PROSPERO 2018 CRD42018089160). We conducted structured electronic searches using key words and specific vocabulary, as well as directed searches in several databases. After validity analysis, we selected 7 studies with observational methodology. We found great variability in the definition of 'difficult peripheral venous access' and in the variables proposed as risk factors. Statistically significant factors through studies include demographic and anthropometric variables (gender, Body Mass Index), as well as medical and health conditions (diabetes, renal insufficiency, parenteral drug abuse, cancer chemotherapy), together with variables related to the vein or vascular access (vein visibility and palpability, vessel diameter, previous history of difficulty). Some studies have also considered variables related to the professional performing the technique. Meta-analyses were carried out for gender and obesity as potential risk factors. Only obesity appeared as a statistically significant risk factor with OR of 1.48; 95% CI (1.03 to 1.93; p = 0.016). Methodological heterogeneity prevented the development of further meta-analyses. It is essential to design future studies with diverse hospital populations, in which a wide selection of potential risk factors can be studied in a unique analysis. Our work identifies the most relevant variables that should be included in those studies.

Incidence of peripheral intravenous catheter failure among inpatients: variability between microbiological data and clinical signs and symptoms.

Background: Peripheral intravenous catheters (PIVCs) are the most widely used invasive devices among inpatients. Catheter-related bloodstream infections (CRBSI) are serious yet preventable events for patients. Although the contribution of PIVCs towards these infections is gradually being recognised, its role in the Spanish setting is yet to be determined. We aimed to estimate the rate and incidence of PIVC failure at Manacor hospital (Spain) as baseline within a wider quality improvement initiative. Methods: Tips from all PIVC removed during December 2017 and January 2018 in hospital wards were cultured semiquantitatively. The study population included all PIVCs inserted in adult patients admitted to any of three medical and one surgical wards, emergency department, critical care unit and operating rooms. Clinical, microbiological and ward information was collected by clinical researchers for each PIVC from insertion to removal on the study sites. CRBSI was defined per international guidelines (i.e., Centers for Disease Control and Prevention, USA). Data was analysed descriptively. Results: Seven hundred and eleven tips were cultured, with 41.8% (297/711) reported as PIVC failure. The PIVC failure rate density-adjusted incidence for hospital length of stay (HLOS) was 226.2 PIVC failure/1000 HLOS. 5.8% (41/711) tips yielded positive isolates, with most frequent microorganisms Staphylococcus spp (S. epidermidis 29/41, 70.7%, S. aureus 2/41, 4.9%, S. hominis 2/41, 4.9%), and Acinetobacter baumannii (1/41, 2.4%). One S. aureus isolate was methicillin-resistant. 53.6% (22/41) positive cultures were obtained from patients with local signs and symptoms compatible with catheter-related infection (CRI), 2.4% (1/41) were compatible with CRBSI type 2 and that clinical signs improve within 48 h of catheter removal (density-adjusted incidence for hospital stays of 16.7 PIVC-CRI/1000 hospital-stays and 0.76 PVC-BSI/1000 hospital-stays respectively) and no patients were diagnosed CRBSI type 3 with a bacterial growth concordant in tip and blood cultures. Most cases responded favourably to catheter removal and management. Conclusions: Our findings show that almost 42% PIVCs resulted in unplanned removal, amplifying the importance in terms of morbidity, mortality and patient safety. A high number of positive tip cultures without clinical signs and symptoms was observed. We underpin the importance to remove unnecessary PIVCs for the prevention of CRBSI.

Appraising the quality standard underpinning international clinical practice guidelines for the selection and care of vascular access devices: a systematic review of reviews.

OBJECTIVE: Catheter-related bloodstream infections are one of the most important adverse events for patients. Evidence-based practice embraces interventions to prevent and reduce catheter-related bloodstream infections in patients. At present, a growing number of guidelines exist worldwide. The purpose of the study was to assess clinical practice guidelines for peripheral and central venous access device care and prevention of related complications. DESIGN: Systematic review of clinical practice guidelines: We conducted a search of the literature published from 2005 to 2018 using Medline/PubMed, Embase, CINAHL, Ovid, ScienceDirect, Scopus and Web of Science. We also evaluated grey literature sources and websites of organisations that compiled or produced guidelines. Guideline quality was assessed with the Appraisal of Guidelines for Research and Evaluation, Second Edition tool by three independent reviewers. Cohen's kappa coefficient was used to evaluate the concordance between reviewers. RESULTS: We included seven guidelines in the evaluation. The concordance between observers was substantial, K=0.6364 (95% CI 0.0247 to 1.2259). We identified seven international guidelines, which scored poorly on crucial domains such as applicability (medium 39%), stakeholder involvement (medium 65%) and methodological rigour (medium 67%). Guidelines by Spanish Health Ministry and UK National Institute for Health and Care Excellence presented the highest quality. CONCLUSIONS: It is crucial to critically evaluate the validity and reliability of clinical practice guidelines so the best, most context-specific document is selected. Such choice is a necessary prior step to encourage and support health organisations to transfer research results to clinical practice. The gaps identified in our study may explain the suboptimal clinical impact of guidelines. Such low adoption may be mitigated with the use of implementation guides accompanying clinical documents.

Mapeo de variabilidad sobre prácticas enfermeras relacionadas con el acceso vascular en el entorno de hemodiálisis. Estudio transversal / Mapping of variability on nursing practices in the hemodialysis environment. Cross-sectional study

Introducción: La Variabilidad de la Práctica Asistencial se define como "aquella situación en la cual pacientes con una clínica similar no son cuidados ni tratados de la misma forma en diferentes niveles de atención, sin que exista una base sólida en conocimientos derivados del cumplimiento de guías de práctica clínica". Objetivo: Analizar la adherencia de las enfermeras a recomendaciones basadas en evidencias, comparar la adherencia respecto a las características sociodemográficas e identificar intervenciones con mayor variabilidad en el manejo del acceso vascular. Material y Método: Estudio observacional transversal. Los sujetos de estudio fueron enfermeras de hemodiálisis que contestaron un cuestionario online ad hoc formado por 33 preguntas a través de GoogleForm, difundido por correo electrónico a nivel nacional durante los meses de octubre y noviembre de 2017. El cuestionario se organizó para dar respuesta a las variables del perfil sociodemográfico y a la adherencia a recomendaciones basadas en las guías KDOQI, detectando 7 dominios fundamentales para la práctica enfermera en hemodiálisis. Resultados: Se obtuvieron 217 encuestas válidas procedentes de 17 comunidades autónomas, lo que supone una tasa de respuesta del 16,69%. La adherencia a las recomendaciones resultó moderada, un 53,24% de las respuestas coincidieron con la evidencia emitida en las guías de práctica clínica. Las intervenciones con mayor incertidumbre y variabilidad están relacionadas con el uso del antiséptico, tipo y tiempo de apósitos y técnica de punción. Conclusión: Se obtuvo una adherencia moderada sobre las áreas de conocimiento que están produciendo mayor incertidumbre en los entornos de hemodiálisis, siendo el mapeo de variabilidad un instrumento útil para su detección

Introduction: The Variability of the Care Practice is defined as "that situation in which patients with a similar clinical situation are not cared for or treated in the same way in different levels of care, without a solid base in knowledge derived from the compliance with clinical practice guidelines". Objective: To analyze the adherence of nurses to recommendations based on evidence, to compare adherence in relation to sociodemographic characteristics and to identify interventions with greater variability in the management of vascular access. Material and Method: Cross-sectional observational study. The study subjects were hemodialysis nurses who answered an ad hoc online questionnaire formed by 33 questions through GoogleForm, disseminated by email at national level, during October and November 2017. The questionnaire was organized to respond the variable of the sociodemographic profile and adherence to recommendations based on the KDOQI guidelines, detecting 7 fundamental domains for nursing practice in hemodialysis. Results: 217 valid surveys were obtained from 17 autonomous communities, which implies a response rate of 16.69%. Adherence to the recommendations was moderate, 53.24% of respondents agreed with the evidence issued in clinical practice guidelines. Interventions with greater uncertainty and variability are related to the use of the antiseptic, type and time of wound dressings, and puncture technique. Conclusion: A moderate adherence was obtained related to the areas of knowledge that are producing greater uncertainty in hemodialysis environments, being the mapping of variability a useful instrument for such detection

Implementation of a knowledge mobilization model to prevent peripheral venous catheter-related adverse events: PREBACP study-a multicenter cluster-randomized trial protocol.

BACKGROUND: Peripheral venous catheters are the most commonly used invasive devices in hospitals worldwide. Patients can experience multiple adverse events during the insertion, maintenance, and management of these devices. Health professionals aim to resolve the challenges of care variability in the use of peripheral venous catheter through adherence to clinical practice guidelines. The aim of this cluster-randomized controlled trial is to determine the efficacy of a multimodal intervention on incidence of adverse events associated with the use of peripheral venous catheters in adult hospital patients. Additional aims are to analyze the fidelity of nurses and the relationship between contextual factors on the use of best available and the outcomes of the intervention. METHODS: Five public hospitals in the Spanish National Health System, with diverse profiles, including one university hospital and four second-level hospitals, will be included. In total, 20 hospitalization wards will be randomized for this study by ward to one of two groups. Those in the first group receive an intervention that lasts 12 months implementing evidence-based practice in healthcare related to peripheral catheters through a multimodal strategy, which will contain updated and poster protocols insertion, maintenance and removal of peripheral venous catheters, technologies applied to e-learning, feedback on the results, user and family information related to peripheral catheter, and facilitation of the best evidence by face-to-face training session. PRIMARY OUTCOME MEASURES: Incidence of adverse events associated with the use of peripheral venous catheters is measured by assessing hospital records. SECONDARY OUTCOME MEASURES: Nurses' adherence to clinical practice guidelines, clinical outcomes, and the cost of implementing the multimodal intervention. DISCUSSION: Clinical implementation is a complex, multifaceted phenomenon which requires a deep understanding of decision-making, knowledge mobilization, and sense making in routine clinical practice. Likewise, the inclusion of strategies that promote fidelity to recommendations through multicomponent and multimodal intervention must be encouraged. The use of a transfer model could counterbalance one of the greatest challenges for organizations, the evaluation of the impact of the implementation of evidence in the professional context through quality indicators associated with prevention and control of infections.
