HOspitals and patients WoRking in Unity (HOW R U?): telephone peer support to improve older patients' quality of life after emergency department discharge in Melbourne, Australia-a multicentre prospective feasibility study.

OBJECTIVES: To ascertain the feasibility and acceptability of the HOW R U? programme, a novel volunteer-peer postdischarge support programme for older patients after discharge from the emergency department (ED). DESIGN: A multicentre prospective mixed-methods feasibility study. SETTING: Two tertiary hospital EDs in metropolitan Melbourne, Australia. PARTICIPANTS: A convenience sample of 39 discharged ED patients aged 70 years or over, with symptoms of social isolation, loneliness and/or depression. INTERVENTION: The HOW R U? intervention comprised weekly social support telephone calls delivered by volunteer peers for 3 months following ED discharge. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcomes were feasibility of study processes, intervention acceptability to participants and retention in the programme. Secondary outcomes were changes in loneliness level (UCLA-3-3-item Loneliness Scale), mood (5-item Geriatric Depression Scale) and health-related quality of life (EQ-5D-5L and EQ-VAS) postintervention. RESULTS: Recruitment was feasible, with 30% of eligible patients successfully recruited. Seventeen volunteer peers provided telephone support to patient participants, in addition to their usual hospital volunteer role. HOW R U? was well received, with 87% retention in the patient group, and no attrition in the volunteer group.The median age of patients was 84 years, 64% were female, and 82% lived alone. Sixty-eight per cent of patients experienced reductions in depressive symptoms, and 53% experiencing reduced feelings of loneliness, and these differences were statistically significant Patient feedback was positive and volunteers reported great satisfaction with their new role. CONCLUSION: HOW R U? was feasible in terms of recruitment and retention and was acceptable to both patients and volunteers. The overall results support the potential for further research in this area and provide data to support the design of a definitive trial to confirm the observed effects.

HOspitals and patients WoRking in Unity (HOW R U?): protocol for a prospective feasibility study of telephone peer support to improve older patients' quality of life after emergency department discharge.

INTRODUCTION: Older people presenting to an emergency department (ED) have a higher likelihood of social isolation, loneliness and depression; which are all associated with negative health outcomes and increased health service use, including higher rates of ED attendance. The HOW R U? study aims to ascertain the feasibility and acceptability of a postdischarge telephone support programme for older ED patients following discharge. The intervention, which aims to improve quality of life, will be delivered by hospital-based volunteers. METHODS AND ANALYSIS: A multicentre prospective uncontrolled feasibility study will enrol 50 community-dwelling patients aged ≥70 years with symptoms of loneliness or depression who are discharged home within 72 hours from the ED or acute medical ward. Participants will receive weekly supportive telephone calls over a 3-month period from a volunteer-peer. Feasibility will be assessed in terms of recruitment, acceptability of the intervention to participants and level of retention in the programme. Changes in level of loneliness (UCLA-3 item Loneliness Scale), mood (Geriatric Depression Scale-5 item) and health-related quality of life (EQ-5D-5L and EQ-VAS) will also be measured postintervention (3 months). ETHICS AND DISSEMINATION: Research ethics and governance committee approval has been granted for this study by each participating centre (reference: 432/15 and 12-09-11-15). Study findings will inform the design and conduct of a future multicentre randomised controlled trial of a postdischarge volunteer-peer telephone support programme to improve social isolation, loneliness or depressive symptoms in older patients. Results will be disseminated through peer-reviewed journal publication, and conference and seminar presentation. TRIAL REGISTRATION NUMBER: ACTRN12615000715572, Pre-results.

Audit of emergency department assessment and management of patients presenting with community-acquired needle stick injuries.

OBJECTIVES: To describe characteristics and management of people with community acquired needle stick injuries (CANSI) attending urban emergency departments; and suggest a guideline to improve assessment, management, and documentation. METHODS: A retrospective analysis of cases with CANSI attending emergency departments in two tertiary hospitals between 2001 and 2005 using medical record review with follow up phone and written survey. RESULTS: Thirty-nine cases met the criteria for CANSI. Persons younger than 30 years sustained 48.72% of all injuries. Source serology was available for only five cases (12.82%). Thirty-one of thirty-nine patients (79.49%) were classed as not immune to hepatitis B but only four of these (12.90%) received both hepatitis B vaccination and hepatitis B immunoglobulin. Six patients (15.38%) received HIV prophylaxis; of which two (33.33%) did not receive baseline HIV testing. Of ten patients referred to immunology clinic for follow up only two (20.00%) attended at 6 months. CONCLUSION: We have identified groups that are at high risk of CANSI, including young males, security workers and cleaners. In the majority of cases protection against hepatitis B was inadequately provided, and a substantial proportion had inadequate baseline assessment and documentation. A guideline is suggested that may be used to improve these deficits.

High prevalence of widened P waves among pediatric patients in 2 separate hospitals.

INTRODUCTION: In adults, P waves of 110 milliseconds or longer are often associated with significant disease. In the pediatric population, however, cutoffs for P-wave durations are naturally lower but could vary physiologically with age because of increasing heart mass. We appraised if age-proportionate increase in P-wave duration does indeed occur in both hospitalized infants and children and also investigated the prevalence of widened P-wave durations using currently accepted "normal" cutoffs (

A randomized controlled trial comparing intranasal fentanyl to intravenous morphine for managing acute pain in children in the emergency department.

STUDY OBJECTIVE: We compare the efficacy of intranasal fentanyl versus intravenous morphine in a pediatric population presenting to an emergency department (ED) with acute long-bone fractures. METHODS: We conducted a prospective, randomized, double-blind, placebo-controlled, clinical trial in a tertiary pediatric ED between September 2001 and January 2005. A convenience sample of children aged 7 to 15 years with clinically deformed closed long-bone fractures was included to receive either active intravenous morphine (10 mg/mL) and intranasal placebo or active intranasal concentrated fentanyl (150 microg/mL) and intravenous placebo. Exclusion criteria were narcotic analgesia within 4 hours of arrival, significant head injury, allergy to opiates, nasal blockage, or inability to perform pain scoring. Pain scores were rated by using a 100-mm visual analog scale at 0, 5, 10, 20, and 30 minutes. Routine clinical observations and adverse events were recorded. RESULTS: Sixty-seven children were enrolled (mean age 10.9 years [SD 2.4]). Fractures were radius or ulna 53 (79.1%), humerus 9 (13.4%), tibia or fibula 4 (6.0%), and femur 1 (1.5%). Thirty-four children received intravenous (i.v.) morphine and 33 received intranasal fentanyl. Statistically significant differences in visual analog scale scores were not observed between the 2 treatment arms either preanalgesia or at 5, 10, 20, or 30 minutes postanalgesia (P=.333). At 10 minutes, the difference in mean visual analog scale between the morphine and fentanyl groups was -5 mm (95% confidence interval -16 to 7 mm). Reductions in combined pain scores occurred at 5 minutes (20 mm; P=.000), 10 minutes (4 mm; P=.012), and 20 minutes (8 mm; P=.000) postanalgesia. The mean total INF dose was 1.7 microg/kg, and the mean total i.v. morphine dose was 0.11 mg/kg. There were no serious adverse events. CONCLUSION: Intranasal fentanyl delivered as 150 microg/mL at a dose of 1.7 microg/kg was shown to be an effective analgesic in children aged 7 to 15 years presenting to an ED with an acute fracture when compared to intravenous morphine at 0.1 mg/kg.

Impact of streaming "fast track" emergency department patients.

OBJECTIVE: Fast track systems to stream emergency department (ED) patients with low acuity conditions have been introduced widely, resulting in reduced waiting times and lengths of stay for these patients. We aimed to prospectively assess the impact on patient flows of a fast track system implemented in the emergency department of an Australian tertiary adult teaching hospital which deals with relatively few low acuity patients. METHODS: During the 12-week trial period, patients in Australasian Triage Scale (ATS) categories 3, 4 and 5 who were likely to be discharged were identified at triage and assessed and treated in a separate fast track area by ED medical and nursing staff rostered to work exclusively in the area. RESULTS: The fast track area managed 21.6% of all patients presenting during its hours of operation. There was a 20.3% (-18 min; 95%CI, -26 min to -10 min) relative reduction in the average waiting time and an 18.0% (-41 min; 95%CI, -52 min to -30 min) relative reduction in the average length of stay for all discharged patients compared with the same period the previous year. Compared with the 12-week period before the fast track trial, there was a 3.4% (-2.1 min; 95%CI, -8 min to 4 min) relative reduction in the average waiting time and a 9.7% (-20 min; 95%CI, -31 min to -9 min) relative reduction in the average length of stay for all discharged patients. There was no increase in the average waiting time for admitted patients. This was despite major increases in throughput and access block in the study period. CONCLUSION: Streaming fast track patients in the emergency department of an Australian tertiary adult teaching hospital can reduce waiting times and length of stay for discharged patients without increasing waiting times for admitted patients, even in an ED with few low acuity patients.

Community senior first aid training in Western Australia: its extent and effect on knowledge and skills.

OBJECTIVE: To define the extent of Senior First Aid training in a sample of the Western Australian community, and to evaluate the effect of previous training on first aid knowledge and skills. METHODS: A telephone survey of a random sample from suburban Perth and rural Western Australia; and practical assessment of first aid skills in a subsample of those surveyed. RESULTS: 30.4% of respondents had completed a Senior First Aid certificate. Trained individuals performed consistently better in theoretical tests (p=0.0001) and practical management of snakebite (p=0.021) than untrained. However, many volunteers, both trained and untrained, demonstrated poor skills in applying pressure immobilisation bandaging and splinting the limb adequately despite electing to do so in theory. CONCLUSIONS AND IMPLICATIONS: Overall knowledge and performance of first aid skills by the community are poor, but are improved by first aid training courses.

Blood cultures ordered in the adult emergency department are rarely useful.

OBJECTIVES: Although blood cultures are commonly ordered in the emergency department, there is controversy about their utility. This study aimed to determine the usefulness of blood cultures in the management of patients presenting to a tertiary adult teaching hospital emergency department in Perth, Western Australia. METHODS: A detailed chart review was undertaken of all blood cultures taken in our emergency department over a 2-month period. All patients within the hospital having blood cultures taken were identified; from this group, blood cultures originating from the emergency department were reviewed. Data were collected concerning patient demographics, culture indication, vital signs, culture outcome, disposition and alterations in management resulting from the blood culture. RESULTS: 218 blood cultures were ordered from the emergency department during the study period. This represented 4.0% (218/5478) of the total number of patients seen. Of the 218 cultures, only 30 were positive (13% of the study population), with 16 (7.3%) probable contaminants and 14 (6.4 %) true positives. No anaerobic isolates were identified. Of the 14 significantly positive blood cultures, the result influenced management in six patients, resulting in a useful culture rate of 2.8% (6/218). CONCLUSION: Blood cultures are ordered on a significant number of patients seen in the emergency department but rarely alter management. Our findings in conjunction with other studies suggest that eliminating blood cultures in immunocompetent patients with common illnesses such as urinary tract infection, community acquired pneumonia and cellulitis, may significantly reduce the number of blood cultures, producing substantial savings without jeopardizing patient care. This needs prospective study and validation.

Propofol versus midazolam/fentanyl for reduction of anterior shoulder dislocation.

OBJECTIVE: The authors aimed to compare propofol and midazolam/fentanyl for reduction of anterior shoulder dislocations using the modified Kocher's maneuver. METHODS: This was a multicenter, randomized, clinical trial of patients with anterior shoulder dislocation. Patients were randomized to either propofol or midazolam/fentanyl. The randomized drug was titrated to a clinical sedation end point (spontaneous eye closure). One physician sedated the patient. Another, blinded to the drug administered, reduced the shoulder and recorded details of muscle tone and ease of reduction. RESULTS: Eighty-six patients were randomized to treatment with propofol (n = 48) or midazolam/fentanyl (n = 38). Patients in the propofol group had shorter mean times to first wakening (difference in means, 4.6 minutes; 95% confidence interval [CI] = 0.7 to 8.6; p = 0.097) and full consciousness (difference in means, 21.7 minutes; 95% CI = 14.7 to 28.7; p <0.001), had easier shoulder reduction (difference in mean rating, 0.5; 95% CI = 0.0 to 0.9; p = 0.047), and needed fewer reduction attempts (difference in means, 0.5; 95% CI = 0.1 to 1.0; p = 0.02). Patients in the propofol group also had less mean muscle tone at the first reduction attempt (p = 0.08) and needed fewer reduction maneuvers (p = 0.40) but had more respiratory depression (11 vs. six patients; difference in proportions, 7.1%; 95% CI = -11.8 to 26.1; p = 0.58) and had one patient who vomited. CONCLUSIONS: Propofol appears to be as effective as midazolam/fentanyl for reduction of anterior shoulder dislocation using the modified Kocher's maneuver. However, the advantage of shorter wakening times associated with propofol should be weighed against the possibility of adverse events, particularly respiratory depression and vomiting.

Thrombolysis for acute myocardial infarction in Australasia 1999.

OBJECTIVE: To describe revascularization practice for acute myocardial infarction in a sample of Australasian hospitals during 1999. DESIGN: Survey for the 1999 calendar year. SETTING: Hospitals with Australasian College for Emergency Medicine-accredited emergency departments in Australia and New Zealand. PARTICIPANTS: Forty-eight hospitals of 80 surveyed (60%), comprising 15 tertiary and 33 non-tertiary hospitals. MAIN OUTCOME MEASURES: Time from arrival in emergency department to initiation of thrombolytic therapy, site of therapy, agent used, mortality and intracranial haemorrhage rates. RESULTS: Approximately 30% of patients with acute myocardial infarction had revascularization therapy. Sixty-two per cent of patients receiving thrombolytics were given this treatment in the emergency department, the remainder in the coronary care unit. Overall median door-to-needle times were 35.0 min emergency department versus 48.3 min coronary care unit. Streptokinase was used for 58.3% of thrombolysis. In-hospital mortality of thrombolysed patients was 6.7% in the emergency department versus 4.3% in the coronary care unit with intracranial haemorrhage rates of 0.8% emergency department and 0.7% coronary care unit. CONCLUSIONS: Overall times to thrombolysis and outcome rates in this sample were within internationally reported figures. Emergency department times were shorter than in coronary care unit.

Community competence in cardiopulmonary resuscitation.

The aim of this study was to determine community application of cardiopulmonary resuscitation (CPR) skills in an emergency, and, thus, assess the value of training programmes in raising community competence. A cross-sectional telephone survey of the Western Australian population was chosen randomly (n = 803). An urban sub-sample (n = 100) performed a practical demonstration of CPR skills using a simulated collapse scenario using a recording manikin as the victim. Performance was assessed by two observers using pre-determined criteria. Of all respondents, 64% had been trained in CPR. Practical and theoretical assessment scores were significantly better in trained versus untrained participants. The number of times a person was trained in CPR was more effective for retention and competence than time since last trained. Degree of training and theoretical competence were less in those aged over 65 years or with heart disease in the household. Theoretical competence poorly reflected practical performance in many tasks. This study provides a comprehensive database of CPR training and performance, and highlights future directions to ensure appropriate and cost-effective training. Specific factors to be addressed include increasing frequency of training, targeting of high-risk groups, simplification in teaching, and emphasising early activation of the emergency medical system.
