ABSTRACT
BACKGROUND: There is little consensus regarding the indications and utility of urinary tract imaging and type of imaging to perform in patients presenting with acute pyelonephritis (APN). AIMS: The aims of this systematic review were to, among patients with APN, (i) identify the proportion of patients investigated with ultrasound (US), (ii) identify the proportion of abnormal US and (iii) identify the proportion of patients with a change in management resulting from abnormal US. METHODS: A comprehensive search covered two electronic databases (Medline and EMBASE), with selection of studies performed independently by two investigators. Inclusion criteria were English language APN diagnosis and quantification of patients assessed with US or abnormal US results. Quality appraisal used the Newcastle-Ottawa instrument. RESULTS: There were 35 studies included. The proportion of patients assessed with US was reported in 16 manuscripts and ranged from 20% to 94%, with significant heterogeneity and publication bias. The proportion of abnormal US was reported in 31 manuscripts and ranged from 7% to 79%. The proportion of abnormal US leading to change in management was reported in five studies and ranged from 7% to 59%. There was marked heterogeneity among studies included in all three subgroups. CONCLUSIONS: Patients with APN are commonly investigated with US, but only a small proportion have abnormalities and appear to be associated with changes in clinical management. The use of routine US for APN is therefore questioned. The identification of clinical variables for appropriate selection of patients to investigate with US requires further research.

OBJECTIVE: We developed a clinical tool comprising patient risk factors for having an abnormal calcium (Ca), magnesium (Mg) or phosphate (PO4) level. We hypothesized that patients without a risk factor do not require testing. This study examined the tool's potential utility for rationalizing Ca, Mg and PO4 ordering in the emergency department (ED). METHODS: We undertook a retrospective observational study in a single metropolitan ED. Patients aged 18 years or more who presented between July and December 2019 were included if they had a Ca, Mg or PO4 test during their ED stay. Demographic and clinical data, including the presence of risk factors, were extracted from the medical record. The primary outcome was a clinically significant abnormal Ca, Mg or PO4 level (>0.2 mmol/l above or below the laboratory reference range). RESULTS: Calcium, Mg and PO4 levels were measured on 1426, 1296 and 1099 patients, respectively. The positive and negative predictive values and likelihood ratios of the tool identifying a patient with a Ca level > 0.2 mmol/l outside the range were 0.05, 0.99, 1.59 and 0.41, respectively. The values for Mg were 0.02, 1.00, 1.44 and 0.35 and those for PO4 were 0.15, 0.93, 1.38 and 0.57, respectively. The majority of patients not identified as having an abnormal level did not receive electrolyte correction treatment. Application of the tool would have resulted in a 35.8% cost reduction. CONCLUSION: The tool failed to predict a very small proportion of patients (approximately 1%) with an abnormal Ca or Mg level and for whom it would have been desirable to have these levels measured. It may help rationalize Ca and Mg ordering and reduce laboratory costs.

OBJECTIVE: To determine author and journal self-citation rates in a sample of original emergency medicine (EM) research articles. METHODS: We undertook a retrospective observational study of original research articles published in 2019 in the top six English language general EM journals. Data comprised the total numbers of articles, citations, authors and self-citations for each author (author self-citations) as well as the number of articles in the reference list that had been previously published in the same journal (journal self-citations). RESULTS: 3213 individual authors and 581 articles were examined. Most authors did not self-cite at all although 62 self-cited five or more times in a single article. The mean (SD) and median (IQR) numbers of individual author self-citations/article/year were 0.6 (1.3) and 0 (0-1), respectively. Overall, author self-citations accounted for 2.4% of all cited articles. There was a weak positive but significant correlation between the number of individual author self-citations/article/year and the number of articles published by the author (r = 0.38, p < 0.001). There was no correlation between the journal impact factor (IF) and the author self-citation rate (r = 0.14, p = 0.79). The journals differed significantly in their author self-citation rates (p < 0.001). Annals of Emergency Medicine had the highest journal self-citation rate at 8.1% (95%CI 7.0%-9.2%) self-citations/100 citations/year, almost twice that of some other journals. There was a large but non-significant positive correlation between the journal IF and journal self-citation rates (r = 0.78, p = 0.07). CONCLUSION: Both author and journal self-citation rates in the articles examined are relatively low compared to other medical and scientific disciplines.

OBJECTIVE: To evaluate the impact of the Southeast Melbourne Virtual Emergency Department (SEMVED) on transfers from residential aged care facilities (RACFs) to traditional EDs. METHODS: A cohort study of residents requesting transfer to the ED via ambulance within participating health networks' catchments from April to June 2022. RESULTS: Two hundred thirty-eight VED consultations occurred with 79% (188/238) avoiding transfer. This represented an avoidance of 12% (188/1511) of all requests for transfer during operating hours. CONCLUSIONS: SEMVED prevented unnecessary transfers and enabled in-facility care. Integration into community outreach programmes could enhance care delivery. Patient safety outcomes were not formally assessed by our methodology.
ABSTRACT
Digital technologies, specifically those required to facilitate telehealth via an audiovisual medium, are now at a standard that allows them to reliably assess patients with acute complaints within their homes. The coronavirus disease 2019 (COVID-19) pandemic forced innovation and led to an increased acceptance of telehealth from both clinicians and patients and presented an opportunity to incorporate telehealth into emergency medicine practice. With inpatient capacity strain exacerbated by the pandemic, three hospital networks within Melbourne's geographical southeast collaborated with Ambulance Victoria (AV) to set up a virtual emergency department (VED) service in January 2022. This service aimed to allow certain patients to receive care in the more convenient setting of their homes. Referrals were made directly by AV personnel at the home while they were attending to these patients. Consultation with a VED clinician was initiated through a secure audiovisual platform, 'Healthdirect'. Following this consultation, care could be facilitated at home through the VED clinician providing advice regarding treatment that paramedics could administer or through linkage into one of the various outreach services provided by the organisations. The VED represents part of the initial integration of telehealth into our organisations. We hope our initial framework might be built upon through greater integration with community services and incorporating more digital technologies. The ongoing graded expansion of telehealth services within our organisations will likely see more and more patients managed in their own homes.

OBJECTIVE: To report the frequency of electric scooter-related trauma and association with alcohol and other drug (AOD) use. METHODS: A retrospective cohort study was conducted, including presentations from 1 January 2017 to 31 May 2022 to a metropolitan health service. RESULTS: There were 272 cases included, with increasing frequency, of which 65 (24%) had AOD exposure. Most AOD-related trauma occurred at night, among males, without helmet use, had higher injury severity, requirement for surgical intervention and longer hospital length of stay. CONCLUSIONS: Urgent preventive measures with a focus on reducing AOD exposure and promoting of helmet use is indicated.

OBJECTIVE: Supported by the state government, three health networks partnered to initiate a virtual ED (VED), as part of a broader roll-out of emergency telehealth services in Victoria. The aim of the present study (Southeast Region Virtual Emergency Department-1 [SERVED-1]) was to report the initial 5-month experience and included all patients assessed through the service over the first 5 months (1 February 2022 to 30 June 2022). METHODS: VED consults occurred after referral from paramedics in the pre-hospital setting. Electronic medical records were retrospectively reviewed for demographic, presenting complaint and outcome data. The primary outcome was the count of VED consultations. The secondary outcome was the proportion of patients where physical ED attendance was avoided within 72 h. The proportion of physical ED attendances avoided sub-grouped by primary presenting complaints were reported. RESULTS: There were 1748 patients who had a VED consultation, of which 1261 (72.1%; 95% confidence interval [CI] 70.0-74.2) patients had physical presentation to an ED avoided in the 72 h following the consult. There was a significant increase in consultations over the 5-month period (incidence rate ratio 1.27; 95% CI 1.23-1.31, P < 0.001) that was consistent in the three health services. The most common presenting complaints were COVID-19 and shortness of breath, and physical presentation was avoided most often among younger patients and those with COVID-19. CONCLUSIONS: Initial experience demonstrated a significant increase in adoption of the service and an overall avoidance of physical ED attendance by a majority of patients. These results support ongoing VED consultations, complemented by follow up and health economic evaluations.

OBJECTIVE: Virtual ED (VED) can potentially alleviate ED overcrowding which has been a public health challenge. The aim of the present study was to conduct a return-on-investment analysis of a VED programme developed in response to changing healthcare needs in Australia. METHODS: An economic model was developed based on initial patient outcome data to assess the healthcare costs, potential costs saved and return on investment (ROI) from the VED. The VED programme operating as part of Alfred Health Emergency Services. The participants were the first 188 patients accessing the Alfred Health VED. VED is the delivery of emergency assessment and management of specific patients virtually via audio-visual teleconferencing. ROI ratios that compare cost savings with intervention costs. RESULTS: The mean total operational cost of VED for 79 days for 188 patients was A$344 117 (95% uncertainty interval [UI] $296 800-$392 088). The VED led to a potential A$286 779 (95% UI $241 688-$330 568) healthcare cost saving from reductions in emergency visits and A$97 569 (95% UI $74 233-$123 117) cost saving in ambulance services. The ROI ratio was estimated at 1.12 (95% UI 0.96-1.32). CONCLUSIONS: The VED was cost neutral in a conservatively modelled scenario but promising if any hospital admission could be saved. Ongoing research examining a larger cohort with community follow up is required to confirm this promising result.

There has been great interest regarding tele-emergency care (TEC) and its utility following the COVID-19 pandemic. We have seen a roll out of multiple TEC services across Australia, operating in isolation, without coordination and under differing models of care, creating the potential for an uncoordinated, inefficient healthcare system. We outline a potential framework under which TEC services might function as part of the current system, defining potential strategies that may be used to appropriately coordinate the acute care of select patients outside of the ED as well as improve the efficiency of the physical ED itself.

OBJECTIVE: To assess patient satisfaction with laceration management, post-ED care, cosmesis and complication rates. METHODS: We undertook a prospective observational study of adult patients with lacerations sutured in two EDs over a 4-month period. ED data included participant demographics, laceration characteristics and management. A telephone survey was undertaken approximately 14 days post-ED discharge. Patient satisfaction with post-ED pain management, advice on wound care and follow up, overall management and wound cosmesis were evaluated using a six-item satisfaction scale (very dissatisfied to very satisfied). Details of wound infection, dehiscence and suture failure were recorded. RESULTS: Eighty-nine patients participated. The number (% [95% confidence interval]) of patients very satisfied with their laceration management were: post-ED pain management 55 (62.5% [51.5-72.4]), wound care advice 51 (57.3% [46.4-67.6]), follow-up advice 39 (43.8% [33.5-54.7]), overall management 61 (68.5% [57.7-77.7]) and cosmetic appearance 46 (51.7% [40.9-62.3]). Infection, dehiscence and suture failure occurred in 5 (5.6%), 8 (9.0%) and 8 (9.0%) cases, respectively. These complications were not associated with being very satisfied overall (P = 0.96). Patients very satisfied with post-ED pain management, wound care advice, follow-up advice or wound cosmesis were much more likely to be very satisfied overall (P < 0.001). CONCLUSIONS: Most patients are very satisfied with their laceration management. However, there is scope for improvement, especially for follow-up and wound care advice. Complications are infrequent and not associated with overall satisfaction.

OBJECTIVE: The aim of the present study was to describe the characteristics and outcomes of patients presenting to Australian EDs with suspected and confirmed COVID-19 during 2020, and to determine the predictors of in-hospital death for SARS-CoV-2 positive patients. METHODS: This analysis from the COVED Project presents data from 12 sites across four Australian states for the period from 1 April to 30 November 2020. All adult patients who met local criteria for suspected COVID-19 and underwent testing for SARS-CoV-2 in the ED were eligible for inclusion. Study outcomes were mechanical ventilation and in-hospital mortality. RESULTS: Among 24 405 eligible ED presentations over the whole study period, 423 tested positive for SARS-CoV-2. During the 'second wave' from 1 July to 30 September 2020, 26 (6%) of 406 SARS-CoV-2 patients received invasive mechanical ventilation, compared to 175 (2%) of the 9024 SARS-CoV-2 negative patients (odds ratio [OR] 3.5; 95% confidence interval [CI] 2.3-5.2, P < 0.001), and 41 (10%) SARS-CoV-2 positive patients died in hospital compared to 312 (3%) SARS-CoV-2 negative patients (OR 3.2; 95% CI 2.2-4.4, P = 0.001). For SARS-CoV-2 positive patients, the strongest independent predictors of hospital death were age (OR 1.1; 95% CI 1.1-1.1, P < 0.001), higher triage category (OR 3.5; 95% CI 1.3-9.4, P = 0.012), obesity (OR 4.2; 95% CI 1.2-14.3, P = 0.024) and receiving immunosuppressive treatment (OR 8.2; 95% CI 1.8-36.7, P = 0.006). CONCLUSIONS: ED patients who tested positive for SARS-CoV-2 had higher odds of mechanical ventilation and death in hospital. The strongest predictors of death were age, a higher triage category, obesity and receiving immunosuppressive treatment.

OBJECTIVE: The aim of the present study was to describe the epidemiology and clinical features of patients presenting to the ED with suspected and confirmed COVID-19 during Australia's 'second wave'. METHODS: The COVID-19 ED (COVED) Project is an ongoing prospective cohort study in Australian EDs. This analysis presents data from 12 sites across four Australian states for the period from 1 July to 31 August 2020. All adult patients who met the criteria for 'suspected COVID-19' and underwent testing for SARS-CoV-2 in the ED were eligible for inclusion. Study outcomes included a positive SARS-CoV-2 test result, mechanical ventilation and in-hospital mortality. RESULTS: There were 106 136 presentations to the participating EDs and 12 055 (11.4%; 95% confidence interval [CI] 11.2-11.6) underwent testing for SARS-CoV-2. Of these, 255 (2%) patients returned a positive result. Among positive cases, 13 (5%) received mechanical ventilation during their hospital admission compared to 122 (2%) of the SARS-CoV-2 negative patients (odds ratio 2.7; 95% CI 1.5-4.9, P = 0.001). Nineteen (7%) SARS-CoV-2 positive patients died in hospital compared to 212 (3%) of the SARS-CoV-2 negative patients (odds ratio 2.3; 95% CI 1.4-3.7, P = 0.001). Strong clinical predictors of the SARS-CoV-2 test result included self-reported fever, sore throat, bilateral infiltrates on chest X-ray, and absence of a leucocytosis on first ED blood tests (P < 0.05). CONCLUSIONS: In this prospective multi-site study during Australia's 'second wave', a substantial proportion of ED presentations required SARS-CoV-2 testing and isolation. Presence of SARS-CoV-2 on nasopharyngeal swab was associated with an increase in the odds of death and mechanical ventilation in hospital.
