Soft collar for acute cervical spine injury immobilisation -patient experiences and outcomes: A single centre mixed methods study.

BACKGROUND: Cervical collars are used as standard care for neck immobilisation after cervical spine injury. Although evidence for the most effective type of collar is lacking, there is evidence regarding adverse patient outcomes when managed in a semi or rigid collar. In response to the evidence of complications and adverse effects when using a hard collar, a large Australian adult trauma hospital that specializes in spinal care, changed its policy from hard to soft collars when managing acute cervical spine injury. OBJECTIVE: The aim of this study was to investigate patients' experiences and outcomes when wearing a soft collar for acute cervical spine injury management in hospital. METHOD: A single centre mixed method sequential study design was used. RESULTS: Medical records from 136 patients were examined and no adverse events resulting from collar use were recorded. Interviews with 20 patients revealed that they understood the value of wearing a soft collar. The soft collars were considered supportive and well tolerated, with good adherence to recommendations for use. CONCLUSIONS: Understanding the patients' experiences informs better care management. This study suggests that soft collars are well tolerated, do not result in pressure injuries or other adverse events and are suitable for managing acute cervical spine injury.

Chemical, Biological, Radiological, or Nuclear Response in Queensland Emergency Services: A Multisite Study.

A disaster overwhelms the normal operating capacity of a health service. Minimal research exists regarding Australian hospitals' capacity to respond to chemical, biological, radiological, or nuclear (CBRN) disasters. This article, and the research supporting it, begins to fill that research gap. We conducted a descriptive quantitative study with 5 tertiary hospitals and 1 rural hospital in Queensland, Australia. The study population was the hospitals' clinical leaders for disaster preparedness. The 25-item survey consisted of questions relating to each hospital's current response capacity, physical surge capacity, and human surge capacity in response to a CBRN disaster. Data were analyzed using descriptive statistics. The survey data indicated that over the previous 12 months, each site reached operational capacity on average 66 times and that capacity to respond and create additional emergency, intensive care, or surgical beds varied greatly across the sites. In the previous 12 months, only 2 sites reported undertaking specific hospital-wide training to manage a CBRN disaster, and 3 sites reported having suitable personal protective equipment required for hazardous materials. There was a noted shortfall in all the hospitals' capacity to respond to a radiological disaster in particular. Queensland hospitals are crucial to CBRN disaster response, and they have areas for improvement in their response and capacity to surge when compared with international preparedness benchmarks. CBRN-focused education and training must be prioritized using evidence-based training approaches to better prepare hospitals to respond following a disaster event.

Investigating the construct and concurrent validity of the Richards-Campbell Sleep Questionnaire with intensive care unit patients and home sleepers.

BACKGROUND: Sleep is vital to our wellbeing. Critically ill patients are vulnerable with effects of sleep deprivation including weakened immune function, decreased glucose tolerance, and increased sympathetic activity. Intensive care unit (ICU) patients' sleep evaluation is difficult and often not reliable. The most commonly used instrument for assessing ICU patients' perspective of their sleep, Richards-Campbell Sleep Questionnaire (RCSQ), has not been reported to have undergone known-group construct validity testing or concurrent validity testing with the criterion measure of feeling refreshed. OBJECTIVES: The aim of the study was to explore the construct validity of the RCSQ with known-groups technique and concurrent validity with the criterion measure of feeling refreshed on awakening. METHODS: A cross-sectional descriptive survey study using the RCSQ was conducted on people sleeping at home (n = 114) over seven nights. The results were compared with the RCSQ sleep scores of nonintubated alert oriented adult ICU patients (n = 114). Home sleepers were also asked to rate how refreshed they felt on awakening. The study was executed and reported in accordance with the STROBE checklist for observational studies. FINDINGS: RCSQ construct validity was supported because home sleepers' and ICU sleepers' sleep evaluations differed significantly. Home sleepers rated their sleep significantly better than ICU patients in all five sleep domains of the RCSQ. Concurrent validity was supported because the item "feeling refreshed on awakening" correlated strongly with all sleep domains. CONCLUSIONS: Sleep quality may be accurately measured using the RCSQ in alert people both in the ICU and at home. This study has added to the validity discussion around the RCSQ. The RCSQ can be used for sleep evaluation in ICUs to promote wellbeing and recovery.

Pressure injury prevalence in Australian intensive care units: A secondary analysis.

BACKGROUND: Pressure injuries (PIs) are an enduring problem for patients in the intensive care unit (ICU) because of their vulnerability and numerous risk factors. METHOD: This study reports Australian data as a subset of data from an international 1-day point prevalence study of ICU-acquired PI in adult patients. Patients aged 18 years or older and admitted to the ICU on the study day were included. The outcome measure was the identification of a PI by direct visual skin assessment on the study day. Data collected included demographic data and clinical risk factors, PI location and stage, and PI prevention strategies used. Descriptive statistics were used to describe PI characteristics, and odds ratios (ORs) were used to identify factors associated with the development of a PI. RESULTS: Data were collected from 288 patients from 16 Australian ICUs. ICU-acquired PI prevalence was 9.7%, with 40 PIs identified on 28 patients. Most PIs were of stage 1 and stage 2 (26/40, 65.0%). Half of the ICU-acquired PIs were found on the head and face. The odds of developing an ICU-acquired PI increased significantly with renal replacement therapy (OR: 4.25, 95% confidence interval [CI]: 1.49-12.11), impaired mobility (OR: 3.13, 95% CI: 1.08-9.12), fastest respiratory rate (OR: 1.05 [per breath per minute], 95% CI: 1.00-1.10), longer stay in the ICU (OR: 1.04 [per day], 95% CI: 1.01-1.06), and mechanical ventilation on admission (OR: 0.36, CI: 0.14-0.91). CONCLUSION: This study found that Australian ICU-acquired PI prevalence was 9.7% and these PIs were associated with many risk factors. Targeted PI prevention strategies should be incorporated into routine prevention approaches to reduce the burden of PIs in the Australian adult ICU patient population.

Utilising the invitational theory provides a framework for understanding assessors' experiences of failure to fail.

AIM: The aim of this paper is to describe how the Invitational Theory were used to frame each of the phases of this sequential mixed methods study to provide valuable insights to the failure to fail phenomenon. BACKGROUND: The assessment of student nurses in clinical courses in undergraduate programmes remains problematic, with some students passing clinical courses when they do not meet standards for practice - failure to fail. Failure to fail is the allocation of passing grades to students who do not meet standards for practice. An understanding of assessors' experiences is central to unravelling the complexities surrounding the phenomenon of failure to fail. Traditionally, such inquiry has been specific and narrow. The Invitational Theory is offered as a comprehensive approach to provide insights and understanding into the complex phenomenon of failure to fail. DESIGN: The five domains of the Invitational Theory; people, processes, programmes, policies and places, were used to inform this sequential exploratory mixed methods study. METHODOLOGY: Phase 1 consisted of an integrative literature review. Phase 2 involved interviews and focus groups with tertiary assessors involved in assessment of students in clinical courses. Phase 3 involved the development, testing and piloting of a survey with tertiary and industry assessors. Phase 4 consisted of a meta-integration of all phases of the study. RESULTS: Key findings of the synthesis of these study phases demonstrated that the domains of the Invitational Theory enable a comprehensive and unique viewpoint of assessment during clinical practicum. All five domains of the Invitational Theory were evident throughout this study and provided unique insights into failure to fail. This research has identified the theoretical underpinnings of the Invitational Theory and its application can be of value in the area of nurse education and specifically assessments. CONCLUSION: The Invitational Theory domains provides a comprehensive and unique viewpoint of assessment of nursing students and contributed to the emerging body of literature regarding failure to fail. How the theoretical framework facilitates the understanding of failure to fail is described in this paper.

Normal saline and lung recruitment with paediatric endotracheal suction (NARES): A pilot, factorial, randomised controlled trial.

BACKGROUND/OBJECTIVE: Endotracheal suction is one of the most common and harmful procuedres performed on mechanically ventilated children. The aim of the study was to establish the feasibility of a randomised controlled trial (RCT) examining the effectiveness of normal saline instillation (NSI) and a positive end-expiratory pressure recruitment manoeuvre (RM) with endotracheal suction in the paediatric intensive care unit. METHODS: Pilot 2 × 2 factorial RCT. The study was conducted at a 36-bed tertiary paediatric intensive care unit in Australia. Fifty-eight children aged less than 16 years undergoing tracheal intubation and invasive mechanical ventilation. (i) NSI or no NSI and (ii) RM or no RM with endotracheal suction . The primary outcome was feasibility; secondary outcomes were ventilator-associated pneumonia (VAP), change in end-expiratory lung volume assessed by electrical impedance tomography, dynamic compliance, and oxygen saturation-to-fraction of inspired oxygen (SpO2/FiO2) ratio. RESULTS/FINDINGS: Recruitment, retention, and missing data feasibility criteria were achieved. Eligibility and protocol adherence criteria were not achieved, with 818 patients eligible and 58 enrolled; cardiac surgery was the primary reason for exclusion. Approximately 30% of patients had at least one episode of nonadherence. Children who received NSI had a reduced incidence of VAP; however, this did not reach statistical significance (incidence rate ratio = 0.12, 95% confidence interval = 0.01-1.10; p = 0.06). NSI was associated with a significantly reduced SpO2/FiO2 ratio up to 10 min after suction. RMs were not associated with a reduced VAP incidence (incidence rate ratio = 0.31, 95% confidence interval = 0.05-1.88), but did significantly improve end-expiratory lung volume at 2 and 5 min after suction, dynamic compliance, and SpO2/FiO2 ratio. CONCLUSION: RMs provided short-term improvements in end-expiratory lung volume and oxygenation. NSI with suction led to a reduced incidence of VAP; however, a definitive RCT is needed to test statistical differences. A RCT of study interventions is worthwhile and may be feasible with protocol modifications including the widening of participant eligibility.

Endotracheal suction interventions in mechanically ventilated children: An integrative review to inform evidence-based practice.

OBJECTIVE: The objective of this study was to review and critically appraise the evidence for paediatric endotracheal suction interventions. DATA SOURCES: A systematic search for studies was undertaken in the electronic databases CENTRAL, Medline, EMBASE, and EBSCO CINAHL from 2003. STUDY SELECTION: Included studies assessed suction interventions in children (≤18 ys old) receiving mechanical ventilation. The primary outcome was defined a priori as duration of mechanical ventilation. Secondary outcomes included adverse events and measures of gas exchange and lung mechanics. DATA EXTRACTION: Data extraction were performed independently by two reviewers. Study methodological quality was assessed using Cochrane's risk of bias tool for randomised trials or the Newcastle-Ottawa Scale for observational studies. Overall assessment of the certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations criteria. RESULTS: Overall 17 studies involving 1618 children and more than 21,834 suction episodes were included in the review. The most common intervention theme was suction system (five studies; 29%). All included trials were at unclear or high risk of performance bias due to the inability to blind interventionists. Current evidence suggests that closed suction may maintain arterial saturations, normal saline leads to significant transient desaturation, and lung recruitment applied after suction offers short-term oxygenation benefit. LIMITATIONS: Lack of randomised controlled trials, inconsistencies in populations and interventions across studies, and imprecision and risk of bias in included studies precluded data pooling to provide an estimate of interventions effect. CONCLUSIONS: Based on the results of this integrative review, there is insufficient high-quality evidence to guide practice around suction interventions in mechanically ventilated children.

Exploring family participation in patient care on acute care wards: A mixed-methods study.

BACKGROUND: Patient- and family-centred care practices are a recommended part of contemporary care for the acutely ill hospitalized adult patients. However, how patient- and family-centred care is enacted in an adult hospital setting is not well understood. AIMS AND OBJECTIVES: The aim of this study is to explore the perceptions of patients, family members and nurses regarding family participation and collaboration in patient care within an acute care setting, including the barriers and facilitators. DESIGN: This study used a mixed-methods sequential design. METHODS: Observer-as-participant observations and semistructured interviews were undertaken. Integration of the data was achieved through triangulation. RESULTS: Triangulation revealed two metathemes. The first metatheme, 'continuum of family involvement', explained the central viewpoint of how family participation and collaboration in the care of acutely ill hospitalized adult patients was enacted. The second metatheme, 'nurses value family involvement', helped to explain and understand the barriers and facilitators to enacting family participation in the acute care setting. CONCLUSION: Promoting family participation in the acute care setting requires supporting multiple levels of engagement. Developing a relationship, clear communication and open sharing of information amongst patients, family members and nurses is critical to supporting family involvement.

Moving forward: Barriers and enablers to failure to fail - A mixed methods meta-integration.

BACKGROUND: Many academics and clinicians who assess nursing students as part of their work-integrated learning experiences encounter difficulties with awarding a failing grade to students who do not meet fitness for practice standards. OBJECTIVES: The aim of this study was to explore and further our understanding of assessors' experiences of failure-to-fail of nursing students within work-integrated learning. DESIGN: This aim was achieved through an exploratory, sequential, mixed methods research project. METHODS: Guided by Invitational Theory, this programme of work included an integrated systematic review, one-on-one and focus group interviews, and finished with a survey. RESULTS: The results of each of the phases of this mixed methods study were integrated to provide a greater understanding of the enablers and barriers for assessors managing poor performing students to ameliorate failure to fail. Enablers identified included: assessor supports, programme flexibility, and organisational culture. The barriers included grade inflation, in appropriate student responses, organisational processes and workload. CONCLUSIONS: This comprehensive integration of a mixed methods study provides new and deeper understanding of the phenomenon of failure to fail. It provides clear recommendations for practical application by tertiary and clinical facilities to enhance the enablers and minimise the barriers to failure where it is warranted.

Normal Saline and Lung Recruitment With Paediatric Endotracheal Suction: A Review and Critical Appraisal of Practice Recommendations.

BACKGROUND: Normal saline instillation (NSI) and lung recruitment manoeuvres (RMs) are used in conjunction with endotracheal suction (ETS) in mechanically ventilated children. Practice is varied, and it is not currently understood what clinical practice guidelines (CPGs) are available to inform practice decisions. OBJECTIVE: The aim of this study was to identify and systematically review the quality of existing ETS CPGs, specifically in the context of NSI and RM use. METHODS: A systematic search for ETS CPGs in children (<18 years old) was conducted in Cumulative Index to Nursing and Allied Health Literature, MEDLINE, PubMed, EMBASE, and Google Scholar. Two independent assessors evaluated CPGs using the Appraisal of Guidelines for Research and Evaluation II instrument. Standardised scores were calculated for individual CPGs, and scale domain scores were calculated. RESULTS: Four CPGs and practice recommendations from 2 literature reviews were identified and evaluated. The routine use of NSI and RMs with paediatric ETS was not recommended. Recommendations reflected the low quality and limited availability of evidence to inform NSI and RM application. Collectively, the highest scoring domain was clarity of presentation, followed by scope and purpose (78). Overall assessments ranged from 8 to 100 from a possible 100 points. Four ETS CPGs (100%) were recommended for use with modification. CONCLUSIONS: Clinical practice guidelines and practice recommendations pertaining to NSI and RM were consistent but, however, limited by the quality and volume of available evidence. Clinical practice guideline developers should focus on improving the applicability and rigour in development processes. Further consensus work and rigorous trials are needed to inform future CPGs.

Partnership between Nurse Navigators and adult persons living with complex chronic disease-An exploratory study.

AIMS AND OBJECTIVES: The aim of this study was to explore nurse navigators and consumers' experience of partnership. BACKGROUND: The nurse navigator has recently emerged as an advanced practice role in the care of persons with complex and chronic disease states. Self-care is an important principle in chronic disease models of care, requiring healthcare practitioners to partner with clients in their care. How nurse navigators and consumers [clients and family] experience partnership has not been explored. DESIGN: An interpretive exploratory qualitative approach was used. Semi-structured interviews were conducted with seven nurse navigators working with adults with complex disease states and eleven of their clients. Interviews were analysed using descriptive content analysis. (COREQ checklist Data S1). RESULTS: Five themes about partnership emerged. Three themes from nurse navigators were as follows: establishing and sustaining relationships, nurse-led planning and aligning care with clients' needs. The two consumer themes were as follows: regular contact means access to the health system and nurse presence is valued. The secondary analysis revealed two themes about partnership between the nurse and consumer: establishing relationships require nursing effort to be established and partnerships are person-focused and nurse-led. CONCLUSIONS: Partnership begins with a relationship, largely driven by the nurse navigator through regular communication and personal contact that was valued by consumers. The nurse-led partnership reduced opportunities for consumers to learn to manage their treatments, particularly how and when to access services, meaning that self-care may not be fully achieved. Client navigation occurs over long periods, which could lead to the navigators being overwhelmed, raising an issue of sustainability. RELEVANCE TO CLINICAL PRACTICE: Nurse navigators establish a client relationship as a foundation for partnership. This partnership needs a focus on promoting client self-care, self-management of treatment, including when and how to access available services, to ensure the sustainability of the nurse navigator model of care.

Measuring assessors' experiences of grading marginal student performances in clinical assessments - The assess-safe tool: Development and preliminary psychometric validation.

Assessment of fitness for practice in the nursing student population is an essential yet challenging component of nursing education. The aim of this research was to describe the development and preliminary validation of the Assess-Safe instrument that explores assessors' experiences of grading nursing student performances in clinical courses when that performance is not a clear pass or fail. A 3 phase approach was used to develop and psychometrically test the instrument. Phase 1 involved the development of a pool of items following a literature review, coupled with findings from qualitative data. In phase 2, an expert panel rated the items for clarity and relevance, reducing the item pool. Assessors of Australian undergraduate nursing students from industry and academia were recruited for this study. A sample of 149 assessors across industry and academia completed the resultant survey to pilot test the instrument; constituting Phase 3. A high content validity index score of 0.95 was achieved through expert review. Construct validity using factor analysis revealed four factors including: assessor support; process support; assessor introspection; and student support. The Assess-Safe instrument achieved good internal reliability with an overall Cronbach's alpha coefficient of 0.77; and sub-scale scores ranging from 0.71 to 0.79. The Assess-Safe instrument demonstrated satisfactory psychometric properties and has utility for education programmes, research and policy development across a variety of practice based professions. Nonetheless, further psychometric validation is warranted.

Adverse events and practice variability associated with paediatric endotracheal suction: An observational study.

OBJECTIVE: The objective of this study was to determine the incidence of endotracheal tube (ETT) suction-related adverse events (AEs) and to examine associations between AEs and patient and suction characteristics. Secondary objectives were to describe ETT suction practices in an Australian paediatric intensive care unit (PICU). METHODS: A prospective, observational study was undertaken in a mixed cardiac and general PICU. Children were eligible for inclusion if they were intubated and mechanically ventilated. Data on patient and suction variables (indication for ETT suction, number of suction episodes per mechanical ventilation episode, indication for normal saline instillation [NSI] and NSI dose) including potential predictive variables (age, Paediatric Index of Mortality 3 [PIM3], NSI, positive end-expiratory pressure, and hyperoxygenation) were collected. The main outcome variable was a composite measure of any AE. MAIN RESULTS: A total of 955 suction episodes were recorded in 100 children. AEs occurred in 211 (22%) ETT suctions. Suction-related AEs were not associated with age, diagnostic category, or index of mortality score. Desaturation was the most common AE (180 suctions; 19%), with 69% of desaturation events requiring clinician intervention. Univariate logistic regression showed the odds of desaturation decreased as the internal diameter of the ETT increased (odds ratio [OR]: 0.59; 95% confidence interval [CI]: 0.37-0.95; p = 0.028). Multivariable modelling revealed NSI was significantly associated with an increased risk of desaturation (adjusted OR [aOR]: 3.23; 95% CI: 1.99-5.40; p < 0.001) and the occurrence of an AE (aOR: 2.76; 95% CI: 1.74-4.37; p < 0.001). Presuction increases in fraction of inspired oxygen (FiO2) was significantly associated with an increased risk of experiencing an AE (aOR: 2.0; 95% CI: 1.27-3.15; p = 0.003). CONCLUSIONS: ETT suction-related AEs are common and associated with NSI and the requirement for pre-suction increases in FiO2. Clinical trial data are needed to identify high-risk patient groups and to develop interventions which optimise practice and reduce the occurrence of ETT suction-related AEs.

Central venous access device Securement and dressing effectiveness: The CASCADE pilot randomised controlled trial in the adult intensive care.

INTRODUCTION: Central venous access devices (CVADs) are a vital medical device for intensive care (ICU) patients; however, complications and failure are common, yet potentially prevented through effective dressings and securement. OBJECTIVES/AIMS: The objective of this study was to test the feasibility of a randomised controlled trial (RCT) comparing standard care with three dressing and securement products to prevent CVAD failure. Secondary aims included comparing dressing and securement products on CVAD failure, microbial colonisation, and intervention costs. METHODS: A single-centre pilot RCT of ICU adult patients requiring CVADs for >24 h were randomised to four groups: (i) sutures plus chlorhexidine gluconate (CHG) dressing (standard care); (ii) standard care plus tissue adhesive (TA); (iii) two sutureless stabilisation devices (SSD) plus CHG dressing; (iv) sutures, CHG disc plus integrated securement dressing (ISD). Descriptive statistics assessed feasibility. Incidence rates (IRs) of CVAD failure were reported, with group differences compared using the Fisher exact and log-rank tests. Cox regression explored univariable risks for failure. A substudy examined bacterial colonisation of catheter tips, dressings, and skin. Cost estimates of the intervention were compared. RESULTS: A total of 121 participants were randomised. Study feasibility was established with no withdrawal and moderate staff acceptability; however, recruitment was low at 12%. Overall CVAD failure was seen in 14 of 114 (12%) CVADs (19 per 1000 catheter-days); highest in the SSD group (IR: 27.3 per 1000 catheter-days [95% confidence interval {CI}: 11.4-65.6]), followed by the standard care group (IR: 22.3 per 1000 catheter-days [95% CI: 8.38-59.5]) and TA group (IR: 20.6 per 1000 catheter-days [95% CI: 6.66-64.0]), and lowest in the ISD group (IR: 8.8 per 1000 catheter-days [95% CI: 2.19-35.0]). The majority of complications (11/14, 79%) were suspected central line-associated bloodstream infection (CLABSI), of which only one was laboratory confirmed (standard care group). The cost per patient was lowest in the standard care group by an average difference of AUD $14. CONCLUSION(S): A large multisite RCT examining forms of securement and dressing is feasible. ISD is the highest priority to test further as it had the lowest failure rate.

Just how bad does it have to be? Industry and academic assessors' experiences of failing to fail - A descriptive study.

BACKGROUND: Failing to fail nursing students in clinical assessments is an internationally acknowledged issue that necessitates thorough examination. Despite the gravity of 'mis-grading' nursing students, current research exploring this subject is limited. Understanding the experiences of assessors when faced with an underperforming student may help illuminate some of the broad issues associated with failure to fail. OBJECTIVES: To describe both tertiary and industry based assessors' experiences of grading nursing student performances in clinical courses when that performance was not a clear pass or fail. DESIGN: A pilot study using a descriptive survey design was employed. SETTING: Participants were drawn from all states and territories in Australia. PARTICIPANTS: Academic and industry assessors of undergraduate nursing students across Australian universities participated in this study. METHODS: A newly developed and validated survey was conducted via an online platform. Descriptive data were collected on assessors' experiences across the domains of the Invitational Theory: people; processes; programmes; policies and places. RESULTS: Participants clearly had a strong duty of care to patients and the nursing profession. However, 23.5% of participants had given the benefit of the doubt to student performances. They reported failing student performances nevertheless reported passing students. Some participants experienced a number of coercive student behaviours. They perceived that the culture of the ward impacted on student performances in assessments. Inadequate time to assess students in clinical practice was reported by 44% of participants. Participants reported no differentiation between theoretical and clinical assessments in their organisations' assessment policies. CONCLUSIONS: Assessors reported many challenges when assessing students who were not performing at requisite standards. This study furthered the extant literature around the impact of people and processes on assessors and failure to fail. For the first time, assessors' experiences of the assessment environment, programme design and organisational policies associated with grading marginal student performances are reported.

"When no-one's looking," the application of lung recruitment and normal saline instillation with paediatric endotracheal suction: An exploratory study of nursing practice.

BACKGROUND: The complex nature of the Paediatric Intensive Care Unit (PICU) patient requires the bedside nurse to make rapid, complex decisions regarding endotracheal suction (ETS) interventions. It is not understood what influences nurses' decision making in the context of ETS, however, the actions of the clinician have a direct impact on the efficacy of the ETS event and patient outcomes. OBJECTIVES: To explore and describe the use of normal saline instillation and lung recruitment with paediatric ETS in a cohort of Australian nurses, and to identify factors that influence normal saline use with ETS. METHODS: A descriptive, exploratory study. An evidence-based practice model formed the conceptual basis for the study. Semi-structured interviews were conducted with 12 nurses from an Australian tertiary referral paediatric intensive care unit. Audiotaped interviews were transcribed. Inductive thematic analysis was used to code and analyse the interview data and identify themes. FINDINGS: Data analysis revealed three themes: patient's clinical presentation, clinician judgement and unit practice norms. CONCLUSIONS: Variability in nurses ETS practice was marked. In the absence of evidence based clinical guidelines, nurses relied on knowledge derived from clinical experience and the local setting to guide NSI and LR intervention decisions. Participants reported uncertainty regarding ETS best practice and perceived the lack of research evidence as a barrier to making informed clinical decisions at the bedside. Rigorous research evaluating the safety and efficacy of NSI and LR with ETS is urgently required for patient care; however PICU nurses rely on multiple sources of evidence to inform ETS practice decision.

Normal saline instillation versus no normal saline instillation And lung Recruitment versus no lung recruitment with paediatric Endotracheal Suction: the NARES trial. A study protocol for a pilot, factorial randomised controlled trial.

INTRODUCTION: Endotracheal suction (ETS) is a frequent and necessary airway intervention for the intubated child. The aim of ETS is to clear the endotracheal tube and airways of respiratory secretions; however, the methods of performing ETS are varied. Internationally a number of ETS treatments are in use. Many have not been rigorously evaluated in a randomised controlled trial setting, and it is uncertain whether any are associated with better outcomes for the critically ill child. With approximately 50% of paediatric intensive care admissions requiring intubation, ETS interventions that maximise the efficacy and minimise the complications of ETS could translate to improved health for substantial numbers of critically ill children, and significant cost savings. The primary aim of the study is to examine two ETS interventions, normal saline instillation and lung recruitment, to determine if it is feasible to conduct a full efficacy trial. METHODS AND ANALYSIS: NARES (Normal saline instillation versus no normal saline instillation And lung Recruitment versus no lung recruitment with paediatric Endotracheal Suction) is a single-centre, pilot, factorial randomised controlled trial conducted in a tertiary referral paediatric centre in Brisbane, Australia. Children (aged 0-16 years) are eligible if they are intubated with an endotracheal tube and mechanically ventilated. Two intervention pairs will be compared using a 2×2 factorial design: (1) normal saline instillation versus no normal saline instillation; and (2) lung recruitment versus no lung recruitment. The primary outcome is study feasibility measured by a composite analysis of eligibility, recruitment, retention, protocol adherence and missing data. Secondary outcomes are ventilator-associated pneumonia, SpO2/FiO2 ratio, lung compliance, end expiratory level and regional tidal volume. ETHICS AND DISSEMINATION: Ethical approval to conduct the research has been obtained. Dissemination of the research findings will be untaken, guided by the Consolidated Standards of Reporting Trials statement recommendations. Protocol content was guided by the Standard Protocol Items: Recommendations for Interventional Trials 2013 statement. TRIAL REGISTRATION NUMBER: ACTRN12617000609358; Pre-results.

A feasibility study of a randomised controlled trial to examine the impact of the ABCDE bundle on quality of life in ICU survivors.

BACKGROUND: Early rehabilitation has been found to prevent delirium and weakness that can hamper the recovery of intensive care unit (ICU) survivors. Integrated clinical practice guidelines for managing patient pain, agitation and delirium (PAD) have been developed. The Awakening and Breathing Coordination, Delirium monitoring/management, and Early exercise/mobility (ABCDE) bundle provides a strategy to implement PAD guidelines into everyday clinical practice. However, there is limited evidence on the effectiveness of the ABCDE bundle in the literature.The purpose of this study was to evaluate the feasibility of conducting a full-scale randomised controlled trial comparing the ABCDE bundle to standard care in an ICU. Trial feasibility was defined as the successful recruitment and retention of trial participants, adherence to the intervention, identification of barriers to the intervention, and the rigorous collection of outcome data. METHODS: A prospective, single-centre, randomised controlled feasibility study was conducted. Thirty adult mechanically ventilated participants were recruited from an eight-bed ICU in south east Queensland, Australia, between April 2015 and December 2015. Participants were randomised to receive either the ABCDE bundle or standard routine management. The ABCDE bundle integrated prescribed awakening and breathing trials, delirium monitoring and management, and prescribed exercise and mobility regimes. Feasibility outcomes measured included recruitment and retention rates, intervention fidelity, and the feasibility of participant outcome data collection. Outcome measurement assessors were blinded to participant assignment. It was not possible to blind the research team or the participant to group assignment. RESULTS: In total, 30 (81.1%) of 37 eligible participants consented and were randomised to the intervention group (n = 15) or the control group (n = 15). Of these, 23 (76.6%) participants successfully completed the 90-day post discharge assessment. A lengthy recruitment period of 8 months was related to overly stringent inclusion and exclusion criteria. Intervention adherence exceeded defined success rates with participation in awakening and breathing trials, delirium monitoring and exercise interventions performed on 80.2, 97.4 and 90.2% of ventilated days respectively. Outcome assessments were successfully and accurately performed at ICU and hospital discharge and 90-day post hospital discharge. Intervention participants were deemed to be delirious on 39.6% of mechanically ventilated days indicating a requirement for a scripted regime to prevent delirium. CONCLUSIONS: With minor adjustment of inclusion and exclusion criteria, the inclusion of delirium management protocols, and encouragement of family engagement and involvement, a large-scale definitive randomised controlled trial to test the impact of the ABCDEF bundle will be feasible.

Long-term cognitive impairment and delirium in intensive care: A prospective cohort study.

BACKGROUND: Whilst there is a growing body of research exploring the effect of delirium in intensive care unit (ICU) patients, the relationship between patient delirium and long-term cognitive impairment has not been investigated in settings where low rates of delirium have been reported. OBJECTIVES: To assess the association between the incidence of delirium, duration of mechanical ventilation and long term cognitive impairment in general ICU patients. METHODS: Prospective cohort study conducted in a tertiary level ICU in Queensland, Australia. Adult medical and surgical ICU patients receiving ≥12h mechanical ventilation were assessed for delirium on at least one day. Cognitive impairment was assessed at three and/or six-months using the: Repeatable Battery for the Assessment of Neuropsychological Status (RBANS); Trail Making Test (TMT) Part A and B; and Mini-Mental State Examination (MMSE). RESULTS: Of 148 enrollees, 91 (61%) completed assessment at three and/or six months. Incidence of delirium was 19%, with 41% cognitively impaired at three months and 24% remaining impaired at six months. Delirium was associated with impaired cognition at six-months: mean TMT Part A scores (information processing speed) were 7.86s longer than those with no delirium (p=0.03), and mean TMT Part B scores (executive functioning) 24.0s longer (p=0.04). CONCLUSIONS: ICU delirium was positively associated with impaired information processing speed and executive functioning at six-months post-discharge for this cohort. Testing for cognitive impairment with RBANS and TMT should be considered due to its greater sensitivity in comparison to the MMSE.

Efficacy and safety of normal saline instillation and paediatric endotracheal suction: An integrative review.

OBJECTIVE: To synthesise research findings regarding the efficacy and safety of normal saline instillation (NSI) during endotracheal suction in the paediatric intensive care unit. DATA SOURCES: The Cochrane Library, PROSPERO, the National Health Service Centre for Reviews and Dissemination, PubMed and Cumulative Index to Nursing and Allied Health (CINAHL) databases were systematically searched. Subject headings included "suctioning, endotracheal", "suction", "sodium chloride", "normal saline" and "paediatrics". Additional references were sourced from hand searches of journal article reference lists and Google Scholar. METHOD: An integrative, systematic approach was used to qualitatively synthesise study results in the context of paediatric intensive care nursing practice. Data were extracted using a standardised data extraction form. Quality assessment was performed independently by two reviewers. RESULTS: Three studies met pre-defined inclusion criteria. Quality of all study methods was 75% on the Mixed Method Appraisal Tool, although reporting quality varied. Overall, there was a scarcity of high quality evidence examining NSI and paediatric endotracheal suction. Outcome measures included oxygen saturation (SpO2), serious adverse events (author/s defined) and ventilation parameters (author/s defined). Endotracheal suction with NSI was associated with a transient decrease in blood oxygen saturation; research protocols did not include interventions to mitigate alveolar derecruitment. Studies were not powered to detect differences in endotracheal tube (ETT) occlusion or ventilator associated pneumonia (VAP). CONCLUSION: NSI was associated with a transient decrease in oxygen saturation. In children with obstructive mucous, NSI may have a positive effect. Practices which maximise secretion removal and mitigate the negative physiological interactions of ETS have been poorly evaluated in the paediatric population. High quality, powered, clinical trials are needed to determine the safety and efficacy of normal saline instillation and to inform clinical practice.
