Redeployment to critical care during the COVID-19 pandemic: A phenomenological study.

BACKGROUND: The redeployment of staff which involves moving staff from one clinical setting to another is a key feature of health care management. Rising demand associated with chronic disease and seasonal variation makes redeployment increasingly commonplace. During the COVID-19 pandemic preparation for the influx of patients included sourcing equipment and resources and the redeployment of staff to respiratory wards and critical care. AIM: The aim of this study was to explore the lived experience of redeployment to critical care during the COVID-19 pandemic from the perspective of those individuals who were moved to help and critical care core staff. STUDY DESIGN: A transcendental phenomenological study involving semi-structured interviews with staff redeployed and critical care core staff was conducted. Data were collected from staff in one critical care department of a large NHS Trust in England between the second and third pandemic wave (April-June 2021). RESULTS: Analysis of the data led to the identification of seven meaning units: intention, apprehension, expectations, familiarity, preparation, support, and own work. Intention related to the decisions made by managers regarding whom to redeploy and the reasons why people were chosen. Apprehension and expectations were closely linked and related to critical care skills and knowledge as well as anxiety about infection risk. Familiarity was a key element of people feeling comfortable and the confidence core staff had in colleagues who had come to help. Support and preparation helped but staff were anxious about their own work and concerned about the open-ended nature of redeployment. CONCLUSION: Familiarity and recency of critical care experience played a significant role in how useful redeployed staff were. Redeployed staff were concerned about assumptions being made and expectations of themselves as well as detachment from their usual support network. RELEVANCE TO CLINICAL PRACTICE: Continued shortages of registered nurses globally combined with the need to create additional critical care capacity during emergencies such as infection outbreaks means that redeployment of staff will continue for some time. Identifying the impact of redeployment on staff will enable services to better prepare and support registered nurses who are redeployed to critical care.

The impact of rapid cycle simulation deliberate practice on nursing student's resuscitation self-efficacy: A quasi-experimental study.

BACKGROUND: Nursing students often report anxiety about the performance of resuscitation in a placement context. Rapid cycle deliberate practice which involves re-running the scenario after de-brief allowing for the correction of errors and improved practice has been widely used to develop skills in resuscitation. Few studies have examined the use of rapid cycle deliberate practice to improve resuscitation confidence and self-efficacy. OBJECTIVE: to assess if rapid cycle deliberate practice leads to improvements in resuscitation self-efficacy in pre-registration nursing students. DESIGN: Quasi-experimental pre and post-test design measuring self-efficacy using the Basic Resuscitation Skills - Self Efficacy Scale. SETTING: University, United Kingdom. PARTICIPANTS: Students were invited to participate (n = 120) and 106 consented to take part in the study. Participants were in pre-determined practical groups with 56 in the experimental group and 50 in the control group. METHODS: A pre and post-test of nursing students' self-efficacy during a resuscitation simulation scenario. The scenario will relate to a patient admitted to the emergency room with chest pain who then goes into cardiac arrest. The control group undertake the simulation exercise and then received a de-brief whereas the experimental group participated in a rerun of the scenario following the de-brief (deliberate practice). Both groups completed the Basic Resuscitation Skills Self-efficacy scale pre and post the session. Data were analysed using a paired sample t-test. RESULTS: Both groups showed improved self-efficacy as a result of the simulation session. The difference in the post-test mean scores between the control and the experimental group was marginal and not statistically significant. CONCLUSION: rapid cycle deliberate practice simulation does not lead to improved resuscitation self-efficacy amongst pre-registration nursing students when compared with a single session. ABSTRACT: Nursing students are often anxious about performing resuscitation in practice. Can rapid cycle deliberate practice improve resuscitation self-efficacy? Pre and post-test study (n=106) showed improved self-efficacy with no statistical difference between standard simulation and deliberate practice.

Nurses' knowledge and self-assessment of their clinical experiences of intraosseous access: A multicentre cross-sectional study.

BACKGROUND: Intraosseous access is an effective and safe option when difficult vascular access occurs. The knowledge, competence, and clinical experience of nurses are collectively essential for the successful implementation of this approach in clinical practice. Education and clinical learning are the main pillars supporting this new practice to ensure patient safety. The aim of this study was to identify the nurses' knowledge and clinical experience of intraosseous access and the factors associated with the adoption of this procedure. METHODS: A cross-sectional study was carried out from October to December 2020. A convenience sample of 432 nurses from four Italian hospitals were involved. A structured questionnaire was used to assess the nurses' knowledge of the intraosseous access guidelines and their clinical experience. RESULTS: Most participants were female (71.5%) with more than 10 years of experience (63.7%) working in an emergency (38.9%) and medical (37.7%) setting. Most of the participants demonstrated their knowledge of the use of a device e.g., it is used if vascular access is not rapidly achieved in a child (83.1%) and the boluses of liquids required in the intraosseous procedure (72.7%). A few participants reported having placed intraosseous access (3.5%). A higher level of educational preparation and working in emergency and paediatric settings were associated with increased knowledge. CONCLUSIONS: Our findings highlighted a sub-optimal level of knowledge of the IO procedure, little experience of this practice in clinical contexts, also associated with a lack of adequate protocols and devices available to nurses. Nurses need to develop their knowledge and practice the skill clinically to embed this practice. University and nurse educators should emphasise the relevance of this practice in nursing education and training, so as to improve the nursing care practice and level of patient safety.

Identifying Sources of Moral Distress Amongst Critical Care Staff During the Covid-19 Pandemic Using a Naturalistic Inquiry.

Introduction: Moral distress can have a significant impact on the mental health and well-being of practitioners. Causes of moral distress in critical care have been identified as futile treatment, conflict between family members and staff, lack of resources, and dysfunctional teams. Objectives: This study explores the sources of moral distress during the COVID-19 pandemic and the meaning that staff attached to these events. The study aims to examine whether the sources of moral distress are similar, or different, to those that commonly occur in critical care departments. Methods: Naturalistic inquiry using semi-structured individual interviews with 17 participants drawn from nursing (n = 12), medicine (n = 3), and the allied health professions (n = 2). The interviews were recorded and transcribed verbatim. The transcripts were analyzed using reflexive thematic analysis. Results: The results suggested that while there were some similar sources of moral distress including caring for dying patients and not being able to provide the usual standard of care, the nature of the disease trajectory and frequency of death had a significant impact. In addition, the researchers found that providing care which was counter-intuitive, concerns about the risks to the staff and their families and the additional burdens associated with leading teams in times of uncertainty were identified as sources of moral distress. Conclusion: This study explored the potential sources of moral distress during the pandemic and the meaning that practitioners attached to their experiences. There were some similarities with the sources of moral distress in critical care which occur outside of a pandemic. However, the frequency and intensity of the experiences are likely to be different during a pandemic, with staff describing high volumes of deaths without family members present. In addition, new sources of moral distress related to uncertainty, counter-intuitive care and concerns about personal and family risk of infection were identified.

Understanding the barriers and facilitators of vaccine hesitancy towards the COVID-19 vaccine in healthcare workers and healthcare students worldwide: An Umbrella Review.

BACKGROUND: Healthcare workers (HCWs) and healthcare students display high levels of vaccine hesitancy with impact on healthcare provision, patient safety, and health promotion. The factors related to vaccine hesitancy have been reported in several systematic reviews. However, this evidence needs to be synthesised, as interventions to reduce vaccination hesitancy in this population are needed. METHODS: This Umbrella Review aimed to explore the barriers and facilitators of vaccine hesitancy toward the COVID-19 vaccine for HCWs and healthcare students. The review was performed and reported in accordance with Joanna Briggs Institutes guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. A protocol was preregistered on PROSPERO (CRD42022327354). Eight databases were searched from November 2019 to 23rd May 2022 to identify any systematic reviews that explored factors associated with hesitancy towards the COVID-19 vaccine for HCWs or healthcare students. RESULTS: A total of 31 studies were included in the review. The majority of studies (71%) were appraised as strong or moderate quality and there was a slight degree of overlap (<5%) of primary studies between the reviews. Vaccine hesitancy was more common among HCWs and healthcare students in specific occupational roles (e.g. nurses) than others (e.g. physicians). Frequent reasons for hesitancy were related to sociodemographic factors (gender, age, ethnicity), occupational factors (COVID-19 exposure, perceived risk, mandatory vaccination), health factors (vaccination history), vaccine-related factors (concerns about safety, efficacy, side-effects, rapid development, testing, approval and distribution of the vaccine), social factors (social pressure, altruism and collective responsibility), distrust factors (key social actors, pandemic management), information factors (inadequate information and sources, exposure to misinformation). CONCLUSION: The results from this Umbrella Review have wide-reaching implications for the research area, healthcare systems and institutions and governments worldwide. Designing tailored strategies for specific occupational groups is pivotal to increasing vaccine uptake and securing a safe healthcare provision worldwide.

Barriers and facilitators of vaccine hesitancy for COVID-19, influenza, and pertussis during pregnancy and in mothers of infants under two years: An umbrella review.

BACKGROUND: Vaccination during pregnancy has been repeatedly demonstrated to be safe and effective in protecting against infection and associated harms for the mother, developing baby, and subsequent infant. However, maternal vaccination uptake remains low compared to the general population. OBJECTIVES: An umbrella review to explore the barriers and facilitators to Influenza, Pertussis and COVID-19 vaccination during pregnancy and within 2 years after childbirth, and to inform interventions to encourage uptake (PROSPERO registration number: CRD42022327624). METHODS: Ten databases were searched for systematic reviews published between 2009 and April 2022 exploring the predictors of vaccination or effectiveness of interventions to improve vaccination for Pertussis, Influenza, or COVD-19. Both pregnant women and mothers of infants under two years were included. Barriers and facilitators were organised using the WHO model of determinants of vaccine hesitancy through narrative synthesis, the Joanna Briggs Institute checklist assessed review quality, and the degree of overlap of primary studies was calculated. RESULTS: 19 reviews were included. Considerable overlap was found especially for intervention reviews, and the quality of the included reviews and their primary studies varied. Sociodemographic factors were specifically researched in the context of COVID-19, exerting a small but consistent effect on vaccination. Concerns around the safety of vaccination particularly for the developing baby were a main barrier. While key facilitators included recommendation from a healthcare professional, previous vaccination, knowledge around vaccination, and communication with and support from social groups. Intervention reviews indicated multi-component interventions involving human interaction to be most effective. CONCLUSION: The main barriers and facilitators for Influenza, Pertussis and COVID-19 vaccination have been identified and constitute the foundation for policy development at the international level. Ethnicity, socioeconomic status, concerns about vaccine safety and side effects, and lack of healthcare professionals' recommendations, are the most relevant factors of vaccine hesitancy. Adapting educational interventions to specific populations, person-to-person interaction, healthcare professionals' involvement, and interpersonal support are important strategies to improve uptake.

Understanding the barriers and facilitators of COVID-19 vaccine hesitancy amongst healthcare workers and healthcare students worldwide: An umbrella review protocol.

Healthcare workers (HCWs) and healthcare students are at increased risk of becoming infected with and being a vector of transmission of COVID-19. Vaccination efforts amongst this group of persons have been hampered in some countries by hesitancy to uptake the COVID-19 vaccine. The factors related to vaccine hesitancy have been reported in several systematic reviews. However, a comprehensive overview of barriers and facilitators of COVID-19 vaccine hesitancy is greatly needed to address effective interventions in this population. Understanding and designing effective strategies to promote vaccination among HCWs is pivotal to secure an appropriate and safe healthcare provision. The current protocol describes the methodology for an Umbrella Review that explores the barriers and facilitators of COVID-19 vaccine hesitancy for HCWs and healthcare students. The databases that will be searched are CINAHL, MedLine, Cochrane Library, PubMed, ProQuest, Web of Science, Science Direct, IBSS, Google Scholar, and Epistemonikos. Studies will be eligible for inclusion if they: (i) conducted a systematic review (with or without meta-analysis); (ii) included primary sources utilizing a quantitative methodology; (iii) investigated factors related to COVID-19 vaccine hesitancy; (iv) and included a sub/population of HCWs or healthcare students aged 18-65. The screening processes and data extraction will be conducted independently by two reviewers. The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Systematic Reviews and Research Syntheses will be used to assess the methodological quality of the included reviews. The degree to which the included reviews contain the same primary studies will also be assessed and reported. The outcomes of this review will have wide-reaching implications for the research area, healthcare systems and institutions, and governments worldwide.

The impact of unsuccessful resuscitation and manikin death during simulation on nursing student's resuscitation self-efficacy: A quasi-experimental study.

BACKGROUND: There has been considerable debate about whether it is appropriate to let the manikin die during simulation teaching. Simulations are used in high-risk industries to recreate rare and potentially catastrophic events. In healthcare, there has been a reluctance to allow scenarios to progress to a catastrophe because of the potential impact on the individual if they were to then encounter the situation in real life. In healthcare, witnessed resuscitation has an overall success rate of around 23.9 %, therefore making every simulation situation successful results in an altered perception of reality. OBJECTIVE: The researchers aimed to examine whether the manikin's death during a simulation adversely affects the resuscitation self-efficacy of nursing students. DESIGN: Quasi-experimental design. SETTING: Univesity of Sunderland, United Kingdom. PARTICIPANTS: Students were invited to participate (n = 120) and 106 consented to take part in the study. METHODS: A pre-and post-test of the nursing student's self-efficacy during a resuscitation scenario. The scenario related to a patient admitted to the emergency room with chest pain who then went into cardiac arrest. The experimental group's resuscitation was unsuccessful, and the control group's resuscitation was successful. Self-efficacy was measured using the validated Basic Resuscitation Skills Self-efficacy scale (BRS-SES). The data were analysed using a paired sample t-test. RESULTS: Overall, both groups showed improved self-efficacy as a result of the simulation session and the death of the manikin in the experimental group did not result in a reduced level of self-efficacy related to resuscitation. CONCLUSION: The death of the manikin during the simulation involving resuscitation had no impact on student resuscitation self-efficacy.

Advanced practice nurse roles in Europe: Implementation challenges, progress and lessons learnt.

BACKGROUND: Advanced practice nursing (APN) roles offer improved access to care and increased quality and more timely care. Despite the advantages of APN roles, there is a disparity between European countries when it comes to implementing APN roles. AIM: To explore the implementation of APN roles in a range of European countries and to explore what factors facilitate or hinder the implementation of these roles. METHODS: A case study evaluation of the process of implementing APN roles. The sample included four countries where APN roles were well developed (Ireland, Spain, Norway and the United Kingdom) and four where APN roles were implemented (Estonia, Slovenia, Cyprus and Romania). Interviews were conducted with key informants (n = 28) from government departments, regulatory bodies, nursing associations and universities. The consolidated criteria for reporting qualitative research (CPREQ) has been used throughout. LIMITATIONS: The small number of countries when considering the size of the region and key informants representing the view of only three to four people in each country. RESULTS: Four themes were identified, including the rationale for the development of the roles, influence, the evolutionary nature of role development and evidence. The data also revealed a mismatch between the perceptions of how the roles develop among the different countries in the early stages of implementation. CONCLUSION: Successful role implementation is dependent upon a tripartite approach between managers, practitioners and educators. An evolutionary approach to role development was used. Regulation and policy come later on in the process of implementation. IMPLICATIONS FOR NURSING POLICY: APN policy should be based on patient needs rather than on the workforce or professional imperatives. The process of implementation can take 15-20 years in total. Recognising the importance of the relationships between service managers and educators is key to the early development of these roles.

Barriers and facilitators to vaccination for COVID-19, pertussis, and influenza during pregnancy: Protocol for an umbrella review.

Pregnant women are particularly vulnerable to infection. Furthermore, infection from pertussis, influenza and COVID-19 increases the likelihood of adverse consequences to the mother and developing baby such as stillbirth, ICU admission, and pre-term caesarean birth. Increased rates of transmission and risk of adverse consequences from infection justifies the provision of national maternal vaccination programmes. Additionally, maternal vaccination helps protect the infant until they are able to receive their own vaccinations; a time when they are most at risk of mortality from influenza and pertussis. Vaccination during pregnancy has been repeatedly demonstrated as safe and effective in reducing harm, although rates of uptake remain low compared to the general population. The current protocol describes the methodology for an umbrella review aiming to explore the barriers and facilitators of vaccination during pregnancy for pertussis, influenza, and COVID-19. Systematic reviews that investigate the barriers and facilitators of at least one of either pertussis, influenza, or COVID-19 will be included in this review. Multiple databases will be searched, and included reviews assessed for quality (using the Joanna Briggs Institute (JBI) quality assessment for systematic reviews) and degree of overlap of included primary studies. Included reviews will be analysed according to the WHO SAGE model of determinants of vaccine hesitancy and separated by whether these explore influenza and pertussis, or COVID-19. The outcomes of this review will help inform the development of interventions to increase uptake of vaccination during pregnancy, and on whether interventions need to be tailored depending on the infectious disease. The key findings will identify the specific barriers and facilitators of vaccination hesitancy by considering contextual influences (e.g. sociodemographic variables), individual/social group influences (e.g. trust in the institutions), and vaccine-specific issues (e.g. safety and recommendations).

Development and Evaluation of the Validity and Reliability of the Leading and Managing Care Pre-Registration Nursing Student Assessment Tool.

BACKGROUND: Clinical nursing leadership influences patient safety and the quality of care provided. Nurses at all levels require leadership and management skills. Despite recognition of the importance of leadership, student nurses often feel ill prepared to make the transition to Registered Nurse and struggle with prioritisation and delegation. In order to standardise student experience and promote the development of skills and attributes, a leadership and management competency assessment was developed and implemented. AIMS: This study aimed to identify the constructs that should be part of an assessment of student nurse competence in relation to clinical nursing leadership, and to evaluate the tool's reliability. METHOD: The first phase was to construct the competency assessment tool, using a mixture of deductive methods, including literature and expert review. Second, psychometric evaluation of the tool, including tests to examine its internal consistency and reliability, comparing test and retest reliability, exploratory factor analysis and generalisability theory analysis to identify reliability and sources of error. RESULTS: Five attributes were identified for inclusion in the tool alongside a scale of competence. 150 assessments were conducted with an average time between each assessment of three days. The results show that the tool was consistent over time with no significant difference in the mean scores. The Cronbach alpha was 0.84 and the tool had good internal consistency. The results of the factor analysis revealed loading onto a single construct. Generalisability theory analysis revealed 0.90 global reliability, with students accounting for the majority of the variation in scores. CONCLUSIONS: The Leading and Managing Care assessment tool represents a valid and reliable assessment of student nurse competence to lead care delivery. Use of the tool during practice placement allows for a structured approach to the development of skills around prioritisation, management of resources, communication and the management of risk.

Patient safety from executive hospital management to wards: A qualitative study identifying factors influencing implementation.

AIM: To examine the journey of safety initiatives from executive hospital management to ward. BACKGROUND: Hospital management teams are often responsible for identifying safety priorities and ensuring delivery of these. METHOD: Naturalistic study design within a large NHS Hospital Trust. Using semi-structured interviews, focus groups and secondary data analysis, the study examines the implementation of safety initiatives. RESULTS: While hospital management developed five safety initiatives, only one of these (falls prevention) was actually seen to permeate all layers of the organisation. Other initiatives stopped one layer down. Both middle management and ward staff added to the list of initiatives developed, resulting in 16 priorities. A range of positive and negative influences to successful implementation are identified. CONCLUSIONS: Safety initiatives need positive reinforcement at all levels to be addressed appropriately. The research suggests that a model related to improvement science may prove useful in ensuring that priorities are addressed. IMPLICATIONS FOR NURSING MANAGEMENT: Care should be taken to ensure that safety initiatives are successfully implemented at all levels within an organisation. Identifying priorities with staff and sharing values and priorities are a key approach to leading such initiatives.

Developing an integrated approach to the assessment of student nurse competence using the Total Client Care (TCC) assessment tool.

The aim of this study was to evaluate the validity and reliability of an integrated assessment of competence using the Total Client Care (TCC) assessment tool within an undergraduate Nursing course. The Total Client Care Assessment Tool aims to assess multiple competencies in an integrated way thereby mirroring the way in which registered nurses are expected to practice. TCC is a tool designed to assess the student's ability to provide holistic care to a client over a specified period of time. TCC measures the student's performance around four constructs, these are: Communication, Planning and Responding, Care Delivery and Assessing and Evaluating. G-theory analysis revealed satisfactory levels of global reliability on single use G co-efficient 0.90 although this dropped to 0.76 when used on eight occasions to assess the same students over a two-year period. Analysis of variance revealed that students and assessment occasions accounted for most of the variance. The TCC assessment tool is useful as it provides data about the student's performance when providing actual care. When used as part of a wider system of assessment involving triangulation of evidence from a number of sources the tool can support mentor judgements about the achievement of competence.

Lessons From Other Disciplines About Communication, Human Performance and Situational Awareness While Wearing Personal Protective Equipment.

INTRODUCTION: The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2/COVID-19) has quickly accelerated into a pandemic. As COVID-19 has swept across the globe, health systems have adapted, including the cessation of routine surgery and the re-deployment of staff to critical care settings. Prompt interventions such as endotracheal (ET) intubation, are deemed essential in patients with Acute Respiratory Distress Syndrome. Intubation requires a coordinated approach and effective teamwork, as it is a high-risk procedure not least because it is an aerosol-generating intervention with increased infection risk. As a result, teams responsible for performing ET intubation are required to wear Personal Protective Equipment (PPE), which in turn hinders communication and situational awareness, and can hamper team work. METHOD: This review considers the effects of wearing PPE on performance and situational awareness in a healthcare environment. Drawing on literature from the fire service and military, the review will explore approaches to improving communication and situational awareness for teams who, at times, are unfamiliar with one another. The review will consider human factors and, identify approaches that assist teams, including teams that are unfamiliar with one another, to adapt to new ways of working while performing high-risk procedures. CONCLUSION: Literature indicates that standardisation, pre-brief and training are important elements of developing improved situational awareness and team working in individuals whose senses may be affected by PPE. In addition, checklists provide a useful way of standardising procedures and can form the basis of a structured pre-brief. Checklists exist for both intubation and patient proning, which, alongside simulation-based team training, provide a useful method of preparing an often unfamiliar workforce for their roles during an epidemic or pandemic. The multi-phase nature of most pandemics provides an opportunity to review processes and implement such procedures, and to develop staff using team-based training during the post-peak period.

Developing Global Leaders for Research, Regulation, and Stewardship of Crop Protection Chemistry in the 21st Century.

To provide sufficient food and fiber to the increasing global population, the technologies associated with crop protection are growing ever more sophisticated but, at the same time, societal expectations for the safe use of crop protection chemistry tools are also increasing. The goal of this perspective is to highlight the key issues that face future leaders in crop protection, based on presentations made during a symposium titled "Developing Global Leaders for Research, Regulation and Stewardship of Crop Protection Chemistry in the 21st Century", held in conjunction with the IUPAC 13th International Congress of Pesticide Chemistry in San Francisco, CA, USA, during August 2014. The presentations highlighted the fact that leaders in crop protection must have a good basic scientific training and understand new and evolving technologies, are aware of the needs of both developed and developing countries, and have good communication skills. Concern is expressed over the apparent lack of resources to meet these needs, and ideas are put forward to remedy these deficiencies.

Improving performance amongst nursing students through the discovery of discrepancies during simulation.

Discrepancy creation is a form of self-regulated learning which can be used to improve individual performance. Discrepancy can be created as a result of comparison against an occupational standard or when an individual strives to achieve higher personal goals. This study explores the process of discrepancy discovery and reduction following simulation sessions. Second year under-graduate nursing students undertook three simulation sessions over a one year period. After each session the participants completed a series of visual analogue scales to rate their own performance and the perceived performance of peers, final year student and a newly registered nurse. Once discrepancy had been identified, participants were asked to produce a short written action plan on how the discrepancy could be addressed and to work on this action plan between sessions. A total of 70 students completed discrepancy scores for all three scenarios. The most common areas of discrepancy were understanding physiology, understanding medicines and pharmacology, patient assessment and handover (hand off). Wilcoxon Signed Ranks suggested a statistically significant difference between student scores in all areas with the exception of team-work. All of the participants used peers as their comparator when identifying discrepancy. There was also a statistically significant difference in the scores following each simulation session suggesting improved performance.

The impact of altered herbicide residues in transgenic herbicide-resistant crops on standard setting for herbicide residues.

The global area covered with transgenic (genetically modified) crops has rapidly increased since their introduction in the mid-1990s. Most of these crops have been rendered herbicide resistant, for which it can be envisaged that the modification has an impact on the profile and level of herbicide residues within these crops. In this article, the four main categories of herbicide resistance, including resistance to acetolactate-synthase inhibitors, bromoxynil, glufosinate and glyphosate, are reviewed. The topics considered are the molecular mechanism underlying the herbicide resistance, the nature and levels of the residues formed and their impact on the residue definition and maximum residue limits (MRLs) defined by the Codex Alimentarius Commission and national authorities. No general conclusions can be drawn concerning the nature and level of residues, which has to be done on a case-by-case basis. International residue definitions and MRLs are still lacking for some herbicide-crop combinations, and harmonisation is therefore recommended.

Safer care at home: use of simulation training to improve standards.

One of the fundamental problems facing providers and commissioners of health services is how to maintain the skills and knowledge of the workforce during the initial development and implementation of home care services. This small-scale project sought to ascertain if it was possible to use human patient simulation scenarios to educate community nurses about how to recognize when care at home is appropriate and when it is not. A series of scenarios were developed and delivered to small groups of community nursing staff. A total of 18 qualified nurses took part in the project. Participants were asked to report their level of confidence in the diagnosis, management and recognition of patient deterioration for each of the scenarios prior to and after the session. The results show increased confidence across all participants in each of the scenarios.

Performing an aseptic technique in a community setting: fact or fiction?

BACKGROUND: Maintaining the principles of asepsis when performing wound care and other invasive procedures is one of the fundamental approaches of preventing healthcare-acquired infection. Such an approach has been advocated for community practitioners. LITERATURE: The performance of an aseptic technique is an under-researched area. The few studies that have been conducted have identified how strict adherence to the technique is difficult and contamination of hands/gloves is common and that community nurses often have a fatalistic view about whether asepsis is possible in a community setting. AIM: The overall aim of this research project was to examine how experienced practitioners have adapted the aseptic technique within a community setting and to what extent the changed procedure still adhered to the principles of asepsis. METHODS: This study used a mixture of non-participant observation and individual semi-structured interviews to examine adherence to the principles of the aseptic technique among the district nurses. Data were collected from one Trust in England with a total of 10 district nurses taking part and 30 aseptic procedures been observed. RESULTS: The results show that almost all of the staff understood the principles of asepsis and had adapted the standard procedure for use in a patient's home. Common challenges included wound cleaning using a single nurse procedure, the contents of the pack and the home environment. The research also identified misconceptions about clean versus aseptic procedures and a lack of training for staff. CONCLUSIONS: This study highlights the challenges of maintaining the principles of asepsis in a home environment and the fact that district nurses are often relied upon to find creative solutions to such challenges. The study also highlights issues around the implementation of evidence-based practice and the need for clearer guidance about how evidence should be used alongside existing procedures.
