Tracheostomy decannulation failure rate following critical illness: A prospective descriptive study

BACKGROUND Tracheostomy is a well established and practical approach to airway management for patients requiring extended periods of mechanical ventilation or airway protection. Little evidence is available to guide the process of weaning and optimal timing of tracheostomy tube removal. Thus, decannulation decisions are based on clinical judgement. The aim of this study was to describe decannulation practice and failure rates in patients with tracheostomy following critical illness. METHODS A prospective descriptive study was conducted of consecutive patients who received a tracheostomy at a tertiary metropolitan public hospital intensive care unit (ICU) between March 2002 and December 2006. Data were analysed using descriptive and inferential tests. RESULTS Of the 823 decannulation decisions, there were 40 episodes of failed decannulation, a failure rate of 4.8%. These 40 episodes occurred in 35 patients: 31 patients failed once, 3 patients failed twice and 1 patient failed three times. There was no associated mortality. Simple stoma recannulation was required in 25 episodes, with none of these patients readmitted to ICU. Translaryngeal intubation and readmission to ICU took place for the remaining 15 episodes. The primary reason for decannulation failure was sputum retention. Twenty-four patients (60%) failed decannulation within 24h, with 14 of these occurring within 4h. CONCLUSIONS Clinical assessments coupled with professional judgement to decide the optimal time to remove tracheostomy tubes in patients following critical illness resulted in a failure rate comparable with published data. Although reintubation and readmission to ICU was required in just over one third of failed decannulation episodes, there was no associated mortality or other significant adverse events. Our data suggest nurses need to exercise high levels of clinical vigilance during the first 24h following decannulation, particularly the first 4h to detect early signs of respiratory compromise to avoid adverse outcomes.

Implementation of a management guideline aimed at minimizing the severity of primary graft dysfunction after lung transplant.

OBJECTIVE Primary graft dysfunction, a severe form of lung injury that occurs in the first 72 hours after lung transplant, is associated with morbidity and mortality. We sought to assess the impact of an evidence-based guideline as a protocol for respiratory and hemodynamic management. METHODS Preoperative and postoperative data for patients treated per the guideline (n = 56) were compared with those of a historical control group (n = 53). Patient data such as ratio of arterial Po(2) to inspired oxygen fraction, central venous pressure, cumulative fluid balance, vasopressor dose, and serum urea and creatinine were measured and documented at specific times. Primary outcome was severity of primary graft dysfunction within the first 72 hours. RESULTS Primary graft dysfunction grade was progressively lower in patients treated after introduction of the guideline (P = .01). Lower postoperative fluid balances (P = .01) and vasopressor doses (P = .007) were seen, with no associated renal dysfunction. There were no differences in duration of mechanical ventilation or mortality. Nonadherence to the guideline occurred in 10 cases (18%). CONCLUSIONS Implementation of an evidence-based guideline for managing respiratory and hemodynamic status is feasible and safe and was associated with reduction in severity of primary graft dysfunction. Further studies are required to determine whether such a guideline would lead to a consistent reduction in severity of primary graft dysfunction at other institutions. Creation of a protocol for postoperative care provides a template for further studies of novel therapies or management strategies for primary graft dysfunction.

Ethical dilemmas of a large national multi‐centre study in Australia: time for some consistency

AIMS AND OBJECTIVES To examine the impact and obstacles that individual Institutional Research Ethics Committee (IRECs) had on a large-scale national multi-centre clinical audit called the National Benchmarks and Evidence-based National Clinical guidelines for Heart failure management programmes Study. BACKGROUND Multi-centre research is commonplace in the health care system. However, IRECs continue to fail to differentiate between research and quality audit projects. METHODS The National Benchmarks and Evidence-based National Clinical guidelines for Heart failure management programmes study used an investigator-developed questionnaire concerning a clinical audit for heart failure programmes throughout Australia. Ethical guidelines developed by the National governing body of health and medical research in Australia classified the National Benchmarks and Evidence-based National Clinical guidelines for Heart failure management programmes Study as a low risk clinical audit not requiring ethical approval by IREC. RESULTS Fifteen of 27 IRECs stipulated that the research proposal undergo full ethical review. None of the IRECs acknowledged: national quality assurance guidelines and recommendations nor ethics approval from other IRECs. Twelve of the 15 IRECs used different ethics application forms. Variability in the type of amendments was prolific. Lack of uniformity in ethical review processes resulted in a six- to eight-month delay in commencing the national study. CONCLUSIONS Development of a national ethics application form with full ethical review by the first IREC and compulsory expedited review by subsequent IRECs would resolve issues raised in this paper. IRECs must change their ethics approval processes to one that enhances facilitation of multi-centre research which is now normative process for health services. RELEVANCE TO CLINICAL PRACTICE The findings of this study highlight inconsistent ethical requirements between different IRECs. Also highlighted are the obstacles and delays that IRECs create when undertaking multi-centre clinical audits. However, in our clinical practice it is vital that clinical audits are undertaken for evaluation purposes. The findings of this study raise awareness of inconsistent ethical processes and highlight the need for expedient ethical review for clinical audits.Aims and objectives.  To examine the impact and obstacles that individual Institutional Research Ethics Committee (IRECs) had on a large-scale national multi-centre clinical audit called the National Benchmarks and Evidence-based National Clinical guidelines for Heart failure management programmes Study.

The diversity of critical care nursing education in Australian universities.

A range of critical care nursing educational courses exist throughout Australia. These courses vary in level of award, integration of clinical and academic competence and desired educational outcomes; this variability potentially leads to confusion by stakeholders regarding educational and clinical outcomes. The study objective was to describe the range of critical care nursing courses in Australia. Following institutional ethics approval, all relevant higher education providers (n=18) were invited to complete a questionnaire about course structure, content and nomenclature. Information about desired professional and general graduate characteristics and clinical competency was also sought. A total of 89% of providers (n=16) responded to the questionnaire. There was little consistency in course structure in regard to the proportion of each programme devoted to core, speciality or generic subjects. In general, graduate certificate courses concentrated on core aspects of critical care, graduate diploma courses provided similar amounts of critical care core and speciality content, while masters level courses concentrated on generic nursing issues. The majority of courses had employment requirements, although only a small proportion specified the minimum level of critical care unit required for clinical experience. The competency standards developed by the Australian College of Critical Care Nurses (ACCCN) were used by 83% of providers, albeit in an adapted form, to assess competency. However, only 60% of programmes used personnel with a combined clinical and educational role to assess such competence. In conclusion, stakeholders should not assume consistency in educational and clinical outcomes from critical care nursing education programmes, despite similar nomenclature or level of programme. However, consistency in the framework for speciality nurse education has the potential to prove beneficial for all stakeholders.

Making decisions: nursing practices in critical care

This article reports the types and complexity level of decisions made in everyday clinical practice by critical care nurses. It also reports factors that influence the complexity of those decisions. A combination of methods were chosen for the two phase study. In the first phase, 12 qualified critical care nurses documented decisions (over a 2 hour period) on a clinical decision recording form designed by the researcher. In the second phase, participants attended a semi-structured focus group. From the analysis, five types of decisions were identified; assessment, intervention, organisation, communication and education. In addition to these documented decisions, three factors that influenced decision complexity were identified from a thematic analysis of the transcribed interviews; communication, patient related and properties of the decision. Nurses reported that communication decisions were the most difficult to make. However, the concept of nurses knowing the patient reduced the level of decision complexity. It is suggested that this has important implications for decision making practices of nurses working in the area of critical care and potentially for patient outcomes.

Clinical nurse research consultant: a clinical and academic role to advance practice and the discipline of nursing

AIMS This article presents a proposal for the Clinical Nurse Research Consultant, a new nursing role. BACKGROUND Although healthcare delivery continues to evolve, nursing has lacked highly specialized clinical and research leadership that, as a primary responsibility, drives evidence-based practice change in collaboration with bedside clinicians. DATA SOURCES International literature published over the last 25 years in the databases of CINAHL, OVID, Medline Pubmed, Science Direct, Expanded Academic, ESBSCOhost, Scopus and Proquest is cited to create a case for the Clinical Nurse Research Consultant. DISCUSSION The Clinical Nurse Research Consultant will address the research/practice gap and assist in facilitating evidence-based clinical practice. To fulfil the responsibilities of this proposed role, the Clinical Nurse Research Consultant must be a doctorally prepared recognized clinical expert, have educational expertise, and possess advanced interpersonal, teamwork and communication skills. This role will enable clinical nurses to maintain and share their clinical expertise, advance practice through research and role model the clinical/research nexus. IMPLICATIONS FOR NURSING Critically, the Clinical Nurse Research Consultant must be appointed in a clinical and academic partnership to provide for career progression and role support. CONCLUSION The creation of the Clinical Nurse Research Consultant will advance nursing practice and the discipline of nursing.

Expanding nurse initiated X-rays in emergency care using team-based learning and decision support

BACKGROUND Triage nurse initiated X-rays (NIXRs) are safe and effective, however, little is known about the ability of other RNs, particularly those without postgraduate qualifications in emergency nursing, to order NIXRs. The aim of this study was to evaluate an innovative NIXR education programme for emergency nurses. METHOD The education programme was multi-faceted, delivered using Team-Based Learning (TBL) and augmented by a decision support checklist. Using a prospective exploratory design, 276 NIXR requests from June to December 2011 were audited. Three groups were compared: (i) RNs with and without postgraduate qualifications irrespective of how they were educated in NIXR, (ii) RNs with and without postgraduate qualifications who undertook the NIXR education programme, and (iii) RNs who did and did not undertake the NIXR programme irrespective of postgraduate qualifications. RESULTS There were 130 NIXRs by 28 RNs with postgraduate qualifications and 146 NIXRs by 12 RNs without postgraduate qualifications. Analysis of all RNs showed RNs without postgraduate qualifications had higher incidence of appropriate NIXRs (83.6% vs 66.2%, p=0.003) however when controlled for the NIXR education programme, statistical significance was lost (83.6% vs 67.5%, p=0.017). RNs who undertook the NIXR education programme had superior documentation of patient assessment findings and higher incidence of appropriate X-ray requests than RNs who did not undertake the NIXR education programme (80.4% vs 65.2%, p=0.042). CONCLUSIONS With appropriate educational preparation, RNs without postgraduate qualifications in emergency nursing can safely engage in NIXR. Structured education using TBL and a decision support checklist produces superior assessment and X-ray requests when compared to ad hoc education and role modelling.

Multidisciplinary Team Developed and Implemented Protocols to Assist Mechanical Ventilation Weaning: A Systematic Review of Literature

AIM The aim of this review was to determine if ventilation-weaning protocols developed and implemented by multidisciplinary teams (MDTs) reduced the duration of mechanical ventilation in adult intensive care patients compared to usual care. METHOD A systematic review was conducted to review published research studies from January 1999 to June 2009 to identify and analyse the best available evidence on MDT-based weaning protocols in adult intensive care patients. All relevant studies based on electronic searches of MEDLINE, EMBASE, CINAHL, the Cochrane Controlled Trials Registry and the Cochrane Database of Systematic Reviews were included. Where possible data were pooled and a meta-analysis performed. A narrative synthesis of data was conducted to provide a critical appraisal of nonrandomised controlled trials included in the review. RESULTS Three pre- and postinterventional studies were identified for inclusion in this review. Results show equivocal support for weaning protocols developed and implemented by MDTs for reducing duration of mechanical ventilation. CONCLUSION Communication and organizational processes must be addressed for multidisciplinary protocols to be effective. Due to methodological limitations of included studies, large randomised controlled trials are required to provide high-level evidence of the effects of MDT-based protocols on duration of mechanical ventilation.

The effect of a staged, emergency department specific rapid response system on reporting of clinical deterioration

BACKGROUND Despite emerging evidence regarding clinical deterioration in emergency department (ED) patients, the widespread uptake of rapid response systems (RRS) in EDs has been limited. AIMS To evaluate the effect of an ED RRS on reporting of clinical deterioration and determine if there were differences between patients who did, and did not, deteriorate during ED care. METHODS A retrospective cross sectional design was used to conduct this single site study in Melbourne, Australia. Stratified random sampling identified 50 patients with shortness of breath, chest pain or abdominal pain per each year studied (2009-2012) giving a total of 600 patients. The intervention was an ED RRS implemented in stages. RESULTS The frequency of clinical deterioration was 14.8% (318 episodes/89 patients). Unreported deterioration decreased each year (86.7%; 68.8%; 55.3%; 54.0%, p=0.141). Patients who deteriorated during ED care had a longer median ED length of stay (2.8h; p<0.001), were 31.9% more likely to need hospital admission (p<0.001) and 4.9% more likely to die in hospital (p=0.044). CONCLUSIONS A staged ED specific RRS decreased the frequency of unreported clinical deterioration. Controlled multi-site studies of ED specific RRSs are needed to examine the effect of formal ED RRSs on patient outcomes.

Patient physiological status during emergency care and rapid response team or cardiac arrest team activation during early hospital admission

Objectives The objective of this study was to examine the relationship between rapid response team (RRT) or cardiac arrest team (CAT) activation within 72 h of emergency admission and (i) physiological status in the emergency department (ED) and (ii) risk for ICU admission and in-hospital mortality. Methods A retrospective matched cohort study was conducted in three hospitals in Melbourne, Australia. The exposed cohort (n=660) included randomly selected adults admitted to the medical or surgical ward through the ED who had RRT or CAT activation within 72 h of admission. Unexposed matched controls (n=1320) did not have RRT or CAT activation. Results The exposed cohort was more likely to have physiological abnormalities fulfilling hospital RRT activation criteria during ED care (36.7 vs. 23.8%, P<0.001). After adjusting for confounders, tachypnoea (adjusted odds ratio=1.92, 95% confidence interval: 1.38–2.67) or hypotension (AOR=1.43, 95% confidence interval: 1.00–2.03), fulfilling RRT activation criteria during ED care, was associated with RRT or CAT activation within 72 h of admission. The exposed cohort had more in-hospital deaths (16.5 vs. 3.6%, P<0.001), more unexpected in-hospital deaths (2.05 vs. 0.2%, P<0.001), more ICU admissions (11.8 vs. 0.7%, P<0.001) and longer lengths of hospital stay (median=8 vs. 5 days, P<0.001). Conclusion CAT/RRT activations within 72 h of emergency admission are associated with higher mortality and increased length of stay. Factors associated with CAT/RRT activation in the wards are often identifiable when patients are in the ED. Further studies are required to determine whether early identification and intervention in patients at risk for RRT or CAT activation can improve their eventual outcomes.
