RESUMEN
ABSTRACT: Background: The association between neutrophil extracellular traps (NETs) and the requirement for vasopressor and inotropic support in vasoplegic shock is unclear. This study aimed to investigate the dynamics of plasma levels of NETs and cell-free DNA (cfDNA) up to 48 h after the admission to the intensive care unit (ICU) for management of vasoplegic shock of infectious (SEPSIS) or noninfectious (following cardiac surgery, CARDIAC) origin. Methods: This is a prospective, observational study of NETs and cfDNA plasma levels at 0H (admission) and then at 12H, 24H, and 48H in SEPSIS and CARDIAC patients. The vasopressor inotropic score (VIS), the Sequential Organ Failure Assessment (SOFA) score, and time spent with invasive ventilation, in ICU and in hospital, were recorded. Associations between NETs/cfDNA and VIS and SOFA were analyzed by Spearman's correlation (rho), and between NETs/cfDNA and ventilation/ICU/hospitalization times by generalized linear regression. Results: Both NETs and cfDNA remained elevated over 48 h in SEPSIS (n = 46) and CARDIAC (n = 30) patients, with time-weighted average concentrations greatest in SEPSIS (NETs median difference 0.06 [0.02-0.11], P = 0.005; cfDNA median difference 0.48 [0.20-1.02], P < 0.001). The VIS correlated to NETs (rho = 0.3-0.60 in SEPSIS, P < 0.01, rho = 0.36-0.57 in CARDIAC, P ≤ 0.01) and cfDNA (rho = 0.40-0.56 in SEPSIS, P < 0.01, rho = 0.38-0.47 in CARDIAC, P < 0.05). NETs correlated with SOFA. Neither NETs nor cfDNA were independently associated with ventilator/ICU/hospitalization times. Conclusion: Plasma levels of NETs and cfDNA correlated with the dose of vasopressors and inotropes administered over 48 h in patients with vasoplegic shock from sepsis or following cardiac surgery. NETs levels also correlated with organ dysfunction. These findings suggest that similar mechanisms involving release of NETs are involved in the pathophysiology of vasoplegic shock irrespective of an infectious or noninfectious etiology.

BACKGROUND: An ageing workforce and increased vacancies has seen a steady growth in nursing student enrolments. This has created a need to re-think how to optimise existing clinical placement opportunities while ensuring quality student experiences and staff satisfaction in their support role. OBJECTIVES: To provide insights into the experiences and satisfaction levels of Registered Nurses who supported nursing students during clinical placement using a facility-based model. DESIGN: A quasi-experimental design. SETTINGS: Three wards in an acute care facility and Primary and Community Health within the Southwest of Sydney, New South Wales, Australia. PARTICIPANTS: Participants included Registered Nurses/Midwives, Facility-based liaison support staff, and Nurse Managers. INTERVENTION: Within the 24/7 facility-based model, each nursing student was allocated to one Registered Nurse for the duration of the clinical placement period. The pair was rostered to complete the same day, evening, night, and weekend shifts. METHODS: A cross-sectional survey related to staff satisfaction was administered to participants at two time points: (a) prior to the commencement of the intervention (baseline survey); and (b) at the completion of the intervention. Following the intervention participants were invited to a focus group or an individual interview. RESULTS: There were no statistically significant changes in the levels of staff satisfaction from baseline to post-intervention; with personal fulfilment scoring the highest and workload the lowest. Staff who worked in the Primary and Community Health settings were less satisfied with this model of student support. Overall, most participants reported high personal satisfaction, professional growth and development opportunities yet acknowledged this came at a cost, with an increased workload. CONCLUSIONS: Participants were satisfied with the facility-based model in supporting student learning on clinical placement. The model is fit for purpose however it does need to be tailored to the contextual needs of nurses working in Primary and Community settings.

Background This study explored the educational and self-management needs of adults living with atrial fibrillation (AF). Methods and Results This is a qualitative study of adults living with AF, clinicians, and expert key stakeholders. Interviews were conducted via a one-to-one semistructured videoconference or phone and transcribed verbatim for thematic analysis. A total of 34 participants were recruited and included in analyses (clinicians n=13; experts n=13, patients n=8). Interviews were on average 40 (range 20-70) minutes in duration. Three key themes were identified: (1) "Patient-centered AF education"; (2) "Prioritizing AF education"; and (3) "Timing AF education." The availability of credible information was perceived as highly variable. Information primarily focused on anticoagulation, or procedural information, as opposed to other aspects of management, such as risk factor reduction. Factors to optimize learning, such as multimedia, apps, case studies, or the use of visuals were perceived as important. Continuity of care, including engagement of caregivers, was important to help develop relationships, and facilitate understanding, while concurrently creating opportunities for timely targeted education. Clinicians described acute care as a suboptimal setting to deliver education. Competing interests aligned with the time-pressured context of acute care were prioritized over patient education. In contrast, patients valued continuity of care. AF education strategies need to pivot from a "one size fits all" approach and modernize to implement a range of approaches. Conclusions There remain many unmet needs in the provision of quality AF education to support self-management. Multimodal offerings and the ability to tailor to individual patient needs are important design considerations for new education programs.

BACKGROUND: Oral care is a fundamental nurse-led intervention in the critical care setting that provides patient comfort and prevents adverse outcomes in critically ill patients. To date, there has been minimal focus on nurse-focused interventions to improve adherence to oral care regimens in the adult intensive care unit setting. OBJECTIVES: The objectives of this study were to (i) identify types and characteristics of interventions to improve oral care adherence amongst critical care nurses and intervention core components, (ii) evaluate the effectiveness of interventions to improve adherence of oral care regimens, and (iii) identify the types of outcome measures used to assess oral care regimen adherence. DESIGN: This is a systematic review in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. DATA SOURCES: Key bibliographic databases and platforms, including Scopus, Cochrane, MEDLINE, CINAHL, Embase, PsycINFO, ProQuest, and Web of Science, were searched for studies published before July 2020. The Joanna Briggs Institute's quality appraisal tool was used to assess risk of bias in included studies. RESULTS: A total of 21 original research studies were identified, of which 18 studies used multifaceted interventions. In accordance with the Joanna Briggs Institute's quality appraisal tools, four of the 20 quasi-experimental studies were rated as high quality. The one randomised control trial was of moderate quality. Outcome measures included oral care adherence behaviours, oral care knowledge, self-reported adherence, and documentation. Improved effectiveness in oral care adherence was reported in 20 studies. CONCLUSIONS: Review findings confirm interventions to change behaviours improve oral care adherence. The most effective interventional approach could not be determined owing to heterogeneity in intervention design and outcome measures. Oral care in the intensive care unit is a vital, nurse-led activity that reduces the risk of hospital-acquired infection. It is recommended that future research adopt implementation science methods to ensure stakeholder engagement and feasibility. SYSTEMATIC REVIEW REGISTRATION NUMBER: This review was submitted and subsequently registered on PROSPERO, the International Perspective Register of Systematic Reviews PROSPERO 2019 CRD42019123142.

BACKGROUND: Health care associated infections (HAI) among adults admitted to the intensive care unit (ICU) have been shown to increase length of stay, the cost of care, and in some cases increased the risk of hospital death (Kaye et al., J Am Geriatr Soc 62:306-11, 2014; Roberts et al., Med Care 48:1026-35, 2010; Warren et al., Crit Care Med 34:2084-9, 2006; Zimlichman et al., JAMA Intern Med 173:2039-46, 2013). Daily bathing with chlorhexidine gluconate (CHG) has been shown to decrease the risk of infection in the ICU (Loveday et al., J Hosp Infect 86:S1-S70, 2014). However, due to varying quality of published studies, and varying estimates of effectiveness, CHG bathing is not universally practiced. As a result, current opinion of the merit of CHG bathing to reduce hospital acquired infections in the ICU, is divergent, suggesting a state of 'clinical equipoise'. This trial sequential meta-analysis aims to explore the current status of evidence for the effectiveness of chlorhexidine (CHG) bathing, in adult intensive care patients, to reduce hospital acquired infections, and address the question: do we need more trials? METHODS: A systematic literature search was undertaken to identify trials assessing the effectiveness of chlorhexidine bathing to reduce risk of infection, among adult intensive care patients. With particular focus on: (1) Blood stream infections (BSI); (2) Central Line Associated Blood Stream Infections (CLABSI); (3) Multi-Resistant Drug Organism (MRDO); (4) Ventilator Associated Pneumonia; and, Catheter Associated Urinary Tract Infections (CAUTI). Only randomised-control or cluster randomised cross-over trials, were include in our analysis. A Trial Sequential Analysis (TSA) was used to describe the current status of evidence for the effectiveness of chlorhexidine (CHG) bathing, in adult intensive care patients, to reduce hospital acquired infections. RESULTS: Five trials were included in our final analysis - two trials were individual patient randomised-controlled, and the remaining cluster-randomised-crossover trials. Daily bathing with CHG was estimated to reduce BSI in the ICU by approximately 29% (Der-Simonian and Laird, Random-Effects. (DL-RE) Incidence Rate Ratio (IRR) = 0.71, 95% confidence interval (CI) 0.51, 0.98); reduce CLABSI in the ICU by approximately 40% (DL-RE IRR = 0.60, 95% CI 0.34, 1.04); reduce MDRO in the ICU by approximately 18% (DL-RE IRR = 0.82, 95% CI 0.69, 0.98); no effect in reducing VAP in the ICU (DL-RE IRR = 1.33, 95% CI 0.81, 2.18); and, no effect in reducing CAUTI in the ICU (DL-RE IRR = 0.77, 95% CI 0.52, 1.15). Upper (superiority) monitoring boundaries from TSA were not crossed for all five specific infections in the ICU. CONCLUSION: Routine bathing with CHG does not occur in the ICU setting, and TSA suggests that more trials are needed to address the current state of 'clinical equipoise'. Ideally these studies would be conducted among a diverse group of ICU patients, and to the highest standard to ensure generalisability of results.

BACKGROUND: Nursing students with English as an additional language (EAL) may underperform academically. The post-enrolment English language assessment (PELA) is used in literacy support, but its predictive validity in identifying those at risk of underperformance remains unknown. OBJECTIVES: To validate a PELA, as a predictor of academic performance. DESIGN: Prospective survey design. SETTING: The study was conducted at a university located in culturally and linguistically diverse areas of western Sydney, Australia. PARTICIPANTS: Commencing undergraduate nursing students who were Australian-born (n=1323, 49.6%) and born outside of Australia (n=1346, 50.4%) were recruited for this study. The 2669 (67% of 3957) participants provided consent and completed a first year nursing unit that focussed on developing literacy skills. METHOD: Between 2010 and 2013, commencing students completed the PELA and English language acculturation scale (ELAS), a previously validated instrument. The grading levels of the PELA tool were: Level 1 (proficient), Level 2 (borderline), and Level 3 (poor, and requiring additional support). RESULTS: Participants with a PELA Level 2 or 3 were more likely to be: a) non-Australian-born (χ(2): 520.6, df: 2, p<0.001); b) spoke a language other than English at home (χ(2): 490.2, df: 2, p<0.001); and c) an international student (χ(2): 225.6, df: 2, p<0.001). There was an inverse relationship between participants' ELAS scores and PELA levels (r=-0.52, p<0.001), and those graded as 'proficient' with a PELA Level 1 were more likely to obtain higher scores in their: i) unit essay assessment (χ(2): 40.2, df: 2, p<0.001); ii) final unit mark (χ(2): 218.6, df: 2, p<0.001), and attain a higher GPA (χ(2): 100.8, df: 2, p<0.001). CONCLUSION: The PELA is a useful screening tool in identifying commencing nursing students who are at risk of academic underachievement.

BACKGROUND: Attrition from nursing programs is common, costly and burdensome to individuals, nursing faculties and the health care system. Increasingly, nursing faculties are requested to monitor attrition rates as a measure of performance, but little is known of the influence of career choice on program completion. OBJECTIVES: The aim of this study was to assess the impact of nursing as a first choice for study on attrition in a baccalaureate nursing program. DESIGN, SETTING AND PARTICIPANTS: A longitudinal, cohort design was used in this study, which involved undergraduate nursing students enrolled at a university in Australia. Of the 357 participants who completed a baseline survey in 2004 at entry to their Bachelor of Nursing program, 352 were followed up over a six-year period to the end of 2009. RESULTS: Students who selected nursing as their first choice for study were nearly twice as likely (OR: 1.99 95% CI: 1.07-3.68) to complete their nursing program compared to those who did not. These students were also more likely to be older (mean age: 26.8 vs 20.1years, P<0.001), and employed in nursing-related work (35% vs 2%, P<0.001). In addition, the study revealed that male students (OR: 1.93 95% CI: 1.07-3.46) and those who worked more than 16h per week during semester (OR: 1.80 95% CI: 1.09-2.99) were less likely to complete than their counterparts. CONCLUSIONS: These data assist in generating realistic projections of completion and entry to the workforce. Understanding patterns of attrition and individuals' motivations to be a nurse is important not only for supporting nursing students to help them complete their studies but also for developing more targeted strategies directed toward student recruitment and retention.

BACKGROUND: Practice nurses are primarily employed by general practitioners, however little is known about the barriers to practice nurse employment from the perspective of general practitioners (GPs). AIM: This paper seeks to explore solo, culturally and linguistically diverse (CALD) general practitioners' perceptions of the practice nurse role, and to identify the barriers and facilitators of these doctors employing nurses within their practice. METHODS: A descriptive study, using semi-structured interviews, was conducted from July to August 2010. Participants were CALD GPs working as solo practitioners who were members of a Division of General Practice in South Western Sydney. Quantitative data were analysed using descriptive statistics and qualitative data were analysed using thematic analysis. RESULTS: The response rate was 51%, however no demographic differences were identified between responders and non-responders. The majority of participants (73%) agreed that practice nurses could perform vital sign measurements or spirometry. Fewer participants (52-63%) believed practice nurses could perform breast checks, pap smears, or assessment of medication regimes. Perceived barriers to employing a practice nurse included lack of space or equipment, legal implications, lack of a specific job description and language communication issues. Participants identified the need for greater financial rebates, assistance with training practice nurses and assistance with business modelling as facilitators to practice nurse employment. CONCLUSION: The feasibility of practice nurse employment in practices with solo, culturally and linguistically diverse general practitioners remains a challenge that needs further exploration. Employment of practice nurses may be a viable option for younger practitioners who have a desire to work in collaborative multidisciplinary models.
