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.

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.

Emergency department presentations of patients from CALDB receiving chemotherapy in day oncology settings

Objective
The objectives of this research were to compare the emergency department (ED) presentations for cancer patients from culturally and linguistically diverse backgrounds (CALDB) treated with chemotherapy through day oncology units with other cancer patients.

Design
A retrospective audit was conducted. Data collected included demographic factors and ED presentation characteristics. Descriptive statistics and direct logistic regression was used to summarise and compare the ED presentation rates and ED presentation characteristics of patients from CALDB and other patients.

Setting
Primary and secondary care.

Patients
All adult day oncology patients who were treated with chemotherapy and presented to an ED between 1 January and 31 December, 2007. Across the two health sites, 770 day oncology patients attended an ED on at least one occasion. Of these 37.7% were born in a non-English speaking country.

Results
Patients from CALDB were more likely to present (p < 0.001, OR = 1.55, C.I. = 1.29–1.88) and re-present to an ED (p < 0.001, OR = 2.08, C.I. = 1.37–3.16), however there was no association between CALDB and admission to hospital following the ED presentation, triage category or being seen within the clinically recommended time. Patients from CALDB tended to present for potentially preventable conditions such as nausea/vomiting/dehydration and fever.

Conclusions
Our findings suggest that targeted interventions that incorporate education and information to assist with self-care for patients from CALDB may reduce potentially preventable presentations and representations to an ED and the subsequent economic, social and personal costs associated with these ED presentations.

Frequency and nature of reported incidents during emergency department care

Background The aim of this study was to examine reported incidents affecting Emergency Department (ED) episodes of care.
Methods A retrospective audit of ED patients was carried out in an urban district hospital in Melbourne, Australia from 1 January 2008 to 31 December 2008. The main outcome measure was presence or absence of reported patient-related incident(s) during ED care.
Results There were 984 patient-related incidents (n¼984) during 2008.The most common incidents were related to patient behaviour (66.4%), patient management (10.1%) and medications (6.5%). Patients whose ED care involved reported incident(s) were older, had higher triage categories, longer length of ED stay and were more likely to need hospital admission or leave at their own risk. Eighteen per cent of reported incidents occurred in patients aged 65 years and over. Incidents affecting older patients were more likely to be related to breach of skin integrity, patient management, diagnosis and patient identification, and less likely to involve patient behaviour.
Conclusions Reported incident(s) occurred in 0.47% of ED episodes of care. Differences in personal and clinical characteristics of patients whose ED care involved reported incident(s) highlights the need for better understanding of incidents occurring in the ED in order to improve systems for high-risk patients.

Early predictors of hospital admission in emergency department patients with chronic obstructive pulmonary disease

Background: Streamlining emergency department (ED) care of patients with chronic obstructive pulmonary disease (COPD) may be an important strategy in managing the increasing burden of this disease.

Study objectives: The aim of this study was to identify factors predictive of hospital admission in ED patients with COPD, specifically factors that can be used early in the ED episode of care.

Methods: Using retrospective regression analysis, case data from 321 randomly selected medical records from five Australian EDs were analysed. Patient characteristics, triage and ED system features, physiological status, and ED treatment during the first four hours of ED care were compared between discharged and admitted patients.

Results: Factors available on ED arrival associated with increased likelihood of admission were: age (OR = 1.04, p = 0.008) respiratory symptoms affecting activities of daily living (OR = 1.8, p = 0.043) and signs of respiratory dysfunction (OR = 2.5, p = 0.005). Factors available from the first four hours of ED care associated with increased likelihood of admission were: age (OR = 1.04, p = 0.021), oxygen use at four hours (OR = 3.5, p = 0.002) and IV antibiotic administration (OR = 2.6, p = 0.026). There were conflicting findings regarding the association between ambulance transport and admission.
