An evidence-based practice approach to improving nursing care of acute stroke in an Australian emergency department

Aims. The aim of this study was to improve the emergency nursing care of acute stroke by enhancing the use of evidence regarding prevention of early complications.
Background. Preventing complications in the first 24–48 hours decreases stroke-related mortality. Many patients spend considerable part of the first 24 hours following stroke in the Emergency Department therefore emergency nurses play a key role in patient outcomes following stroke.
Design. A pre-test/post-test design was used and the study intervention was a guideline for Emergency Department nursing management of acute stroke.
Methods. The following outcomes were measured before and after guideline implementation: triage category, waiting time, Emergency Department length of stay, time to specialist assessment, assessment and monitoring of vital signs, temperature and blood glucose and venous-thromboembolism and pressure injury risk assessment and interventions.
Results. There was significant improvement in triage decisions (21Æ4% increase in triage category 2, p = 0Æ009; 15Æ6% decrease in triage category 4, p = 0Æ048). Frequency of assessments of respiratory rate (p = 0Æ009), heart rate (p = 0Æ022), blood pressure (p = 0Æ032) and oxygen saturation (p = 0Æ001) increased. In terms of risk management, documentation of pressure area
interventions increased by 28Æ8% (p = 0Æ006), documentation of nil orally status increased by 13Æ8% (ns), swallow assessment prior to oral intake increased by 41Æ3% (p = 0Æ003), speech pathology assessment in Emergency Department increased by 6Æ1% (ns) and there was 93Æ5 minute decrease in time to speech pathology assessment for admitted patients (ns).
Relevance to clinical practice. An evidence-based guideline can improve emergency nursing care of acute stroke and optimise patient outcomes following stroke. As the continuum of stroke care begins in the Emergency Department, detailed recommendations for evidence-based emergency nursing care should be included in all multidisciplinary guidelines for the management of acute stroke.

Borderline personality disorder - an overview for emergency clinicians

The diagnosis of borderline personality disorder frequently underlies self-harm and suicidal presentations to the emergency department. Borderline pathology combined with high levels of comorbidity, stigma, and treatment uncertainty, increase the challenges of caring for someone with this diagnosis in an emergency setting. Attributes such as black-and-white thinking and splitting may compromise an already precarious situation. The maintenance of safety requires prioritisation and necessitates a practical and respectful approach, which avoids notions of attention-seeking behaviour. Clinical assessment should distinguish between self-harm and suicide attempts where possible and take into account acute on chronic risk. The emergency clinician will need to consider the degree of containment required in the emergency department and is encouraged to maintain transparency and honesty with the client regarding treatment decisions. If hospitalisation needs to be considered, clinicians should take into account immediate therapeutic benefit versus the counter-therapeutic risk of dependency and regression. Overall, it is reasonable for clinicians to aim for clients to return to their pre-crisis level of functioning, and beneficial for clinicians to approach this client group with therapeutic optimism.

Can the ABCD Score be dichotomised to identify high−risk patients with trainsient ischaemic attack in the emergency department?

Background: Recent evidence shows a substantial short-term risk of ischaemic stroke after transient ischaemic attack (TIA). Identification of patients with TIA with a high short-term risk of stroke is now possible through the use of the “ABCD Score”, which considers age, blood pressure, clinical features and duration of symptoms predictive of stroke.

Aim: To evaluate the ability of dichotomising the ABCD Score to predict stroke at 7 and 90 days in a population with TIA presenting to an emergency department.

Methods: A retrospective audit was conducted on all probable or definite TIAs presenting to the emergency department of a metropolitan hospital from July to December 2004. The ABCD Score was applied to 98 consecutive patients with TIA who were reviewed for subsequent strokes within 90 days. Patients obtaining an ABCD Score ≥5 were considered to be at high risk for stroke.

Results: Dichotomising the ABCD Score categorised 48 (49%) patients with TIA at high risk for stroke (ABCD Score ≥5). This high-risk group contained all four strokes that occurred within 7 days (sensitivity 100% (95% confidence interval (CI) 40% to 100%), specificity 53% (95% CI 43% to 63%), positive predictive value 8% (95% CI 3% to 21%) and negative predictive value 100% (95% CI 91% to 100%)), and six of seven occurring within 90 days (sensitivity 86% (95% CI 42% to 99%), specificity 54% (95% CI 43% to 64%), positive predictive value 12.5% (95% CI 5% to 26%) and negative predictive value 98% (95% CI 88% to 100%)). Removal of the “age” item from the ABCD Score halved the number of false-positive cases without changing its predictive value for stroke.

Conclusion: In this retrospective analysis, dichotomising the ABCD Score was overinclusive but highly predictive in identifying patients with TIA at a high short-term risk of stroke. Use of the ABCD Score in the emergency care of patients with TIA is simple, efficient and provides a unique opportunity to prevent stroke in this population of patients.

Fertile bodies - the sexual politics of contraception : a radical feminist perspective

A critical feminist investigation of the sexual politics of contraception over the last hundred years, within an international context. It is contended that the very idea of contraception perpetuates a "heterosexual monoculture of the body" and as a consequence, men can continue to avoid taking responsibility for their "uncontrolled" fertility.

Effects of education on the therapeutic use of oxygen by emergency nurses

Nurses' factual knowledge increased and oxygen administration decisions improved following education. Variability in nurses' knowledge and decisions, both before and after education, suggests that factual knowledge is only one component of clinical decisions. If nursing education is to improve clinical practice, then we need to better understand the relationship between factual knowledge and clinical decisions.

Psychosocial care of family of critically-ill patients in emergency departments

Responding to families with a critically ill relative is difficult for emergency department clinicians. This innovative research program used best evidence, integrated with perspectives from families and clinicians, to develop context specific guidelines and sensitive tools to assist emergency department clinicians provide quality psychosocial care to meet multidimensional family needs.

Radiation exposure and the justification of computed tomography scanning in an Australian hospital emergency department

In an emergency department (ED), computed tomography (CT) is particularly beneficial in the investigation of high-speed trauma patients. With the advent of multidetector CT (MDCT) scanners, it is becoming faster and easier to conduct scans. In recent years, this has become evident with an increasing number of CT requests. Patients who have multiple CT scans during their hospital stay can receive radiation doses that have an increased theoretical risk of induction of cancer. It is essential that the clinical justification for each CT scan be considered on an individual basis and that due consideration is given to the radiation risk and possible diagnostic benefit. The current lack of a central State or Commonwealth data repository for medical images is a contributing factor to excessive radiation dosage to the population. The principles of justification and radiation risks are discussed in this study.

Older peoples' experience of accessing emergency care

Older ED users are more likely to be seriously ill, arrive by ambulance, spend more time in ED and require hospital admission. The aim of this study was to describe older people’s experiences of accessing Emergency Department (ED) care.

Effect of clinician designation on emergency department fast track performance

Objective To examine the effect of clinician designation on emergency department (ED) fast track performance.
Design and Setting A retrospective audit of patients managed in the fast track area of an ED in metropolitan Melbourne, Australia.
Participants Patients triaged to ED fast track from 1 January 2008 to 31 December 2008 (n=8714).
Main Outcome Measures Waiting times in relation to Australasian triage scale (ATS) recommendations and ED length of stay (LOS) for non-admitted patients were examined for each clinician group.
Results Compliance with ATS waiting time recommendations was highest (82.5%) for emergency nurse practitioners/candidates and lowest (48.2%) for junior medical officers. Median ED LOS was less than 3 h for non-admitted patients, and 85.8% of non-admitted fast track patients (n=6278) left the ED within 4 h. Patients managed by emergency nurse practitioners/ candidates had the shortest ED LOS (median 1.7 h) and patients managed by junior medical officers and locum medical officers the longest ED LOS (median 2.7 h) (x²=498.539, df=6, p<0.001).
Conclusions Clinician designation does impact on waiting times and, to a lesser extent, ED LOS for patients managed in ED fast track systems. Future research should focus on obtaining a better understanding of the relationship between clinician expertise, time-based performance measures and quality of care indicators.
