A retrospective audit of adult and paediatric anaphylaxis management from two Australian metropolitan mixed emergency departments

BackgroundAnaphylaxis is a potentially life-threatening allergic reaction, with presentations to emergency departments (EDs) increasing across Australia. Understanding the features of those presenting with anaphylaxis and aspects related to its optimal clinical management across the admission, treatment and discharge settings is needed to minimise its impact. We aimed to evaluate the nature and management of presentations related to anaphylaxis across two Australian EDs.MethodsRetrospective audit of paediatric and adult patients presenting to a community or tertiary level ED with anaphylaxis from 1 May 2018 to 30 April 2019. Data extracted from medical records included demographic characteristics, causative agents, clinical features, treatments administered across community, ambulance or ED settings, as well as post-discharge care arrangements including provision of Adrenaline Auto-Injector (AAI) and Allergy/Anaphylaxis Action Plan (AAP).ResultsA total of 369 (107 paediatric and 262 adult) ED presentations were identified. A total of 94 (36%) adult and 46 (43%) paediatric patients received pre-hospital adrenaline, with a further 91 (35%) adult and 29 (27%) paediatric patients receiving a dose of adrenaline in the ED. The most commonly administered treatment in ED were corticosteroids, given to 157 (60%) adult and 55 (51%) paediatric patients. Among those requiring an AAI for discharge, 123/210 (59%) adult and 57/91 (63%) of paediatric patients left hospital with an AAI. In contrast, among those requiring an allergy/anaphylaxis action plan (AAP) on discharge, 61/206 (30%) adult and 30/90 (33%) of paediatric patients left hospital with one. Factors associated with an increased likelihood of receiving AAI on discharge in paediatric and adult patients included receipt of any adrenaline, receipt of two or more doses of adrenaline, and longer duration of hospital stay. Adults presenting within business hours were more likely to be discharged with AAI, but no such difference was observed for paediatric patients. Similar findings were evident for provision of AAP on discharge.ConclusionThese findings demonstrate the need to improve assessment and treatment in the ED. In particular, the observed large variability in provision of AAI and AAP on discharge presents opportunities to explore strategies to improve awareness and provision of these critical components of post-discharge care.

Fast-Track Training in Emergency Department During the COVID-19 Pandemic: Evaluation of a Hybrid Education Model.

Emergency department (ED) fast track (FT) for the ambulatory, minor injury patient cohort requires rapid patient assessment, treatment, and turnover, yet specific nursing education is limited. The study aimed to test the feasibility and staff satisfaction of an education program to expand nursing skills and knowledge of managing FT patients during the COVID-19 pandemic. This quasi-experimental study, including self-rating surveys and interviews, assessed the pre- and postimplementation of an education program for nurses working in FT in a metropolitan hospital ED in Australia. Hybrid (face-to-face and Teams) education sessions on 10 topics of staff-perceived limited knowledge were delivered over 8 months. Participants demonstrated higher knowledge scores after the implementation of short online education sessions to cover the core facets of minor injury management. Overall staff satisfaction with the program was high. Interview discussions involved three key themes, including "benefits to staff learning," "positive impact on patient care and flow," and "preferred mode of delivery." Recorded education sessions on minor injury topics for nurses working in FT have proved effective, and this program has now become a core facet of ED education in our hospital.

Applying Sydney Triage to Admission Risk Tool (START) to improve patient flow in emergency departments: a multicentre randomised, implementation study

BackgroundTo determine the effectiveness of applying the Sydney Triage to Admission Risk Tool (START) in conjunction with senior early assessment in different Emergency Departments (EDs).MethodsThis multicentre implementation study, conducted in two metropolitan EDs, used a convenience sample of ED patients. Patients who were admitted, after presenting to both EDs, and were assessed using the existing senior ED clinician assessment, were included in the study. Patients in the intervention group were assessed with the assistance of START, while patients in the control group were assessed without the assistance of START. Outcomes measured were ED length of stay and proportion of patients correctly identified as an in-patient admission by START.ResultsA total of 773 patients were evaluated using the START tool at triage across both sites (Intervention group n = 355 and control group n = 418 patients). The proportion of patients meeting the 4-hour length of stay thresholds was similar between the intervention and control groups (30.1% vs. 28.2%; p = 0.62). The intervention group was associated with a reduced ED length of stay when compared to the control group (351 min, interquartile range (IQR) 221.0–565.0 min versus 383 min, IQR 229.25–580.0 min; p = 0.85). When stratified into admitted and discharged patients, similar results were seen.ConclusionIn this extension of the START model of care implementation study in two metropolitan EDs, START, when used in conjunction with senior early assessment was associated with some reduced ED length of stay.

Patient sex, racial and ethnic disparities in emergency department triage: A multi-site retrospective study

ObjectivesThere is limited evidence on sex, racial, and ethnic disparities in Emergency Department (ED) triage across diverse settings. We evaluated differences in the assignment of Emergency Severity Index (ESI) by patient sex and race/ethnicity, accounting for age, clinical factors, and ED operating conditions. MethodsWe conducted a multi-site retrospective study of adult patients presenting to high-volume EDs from January 2019–February 2020. Patient-level data were obtained and analyzed from three EDs (academic, metropolitan community, and rural community) affiliated with a large health system in the Southeastern United States. For the study outcome, ESI levels were grouped into three categories: 1–2 (highest acuity), 3, and 4–5 (lowest acuity). Multinomial logistic regression was used to compare ESI categories by patient race/ethnicity and sex jointly (referent = White males), adjusted for patient age, insurance status, ED arrival mode, chief complaint category, comorbidity score, time of day, day of week, and average ED wait time. ResultsWe identified 186,840 eligible ED visits with 56,417 from the academic ED, 69,698 from the metropolitan community ED, and 60,725 from the rural community ED. Patient cohorts between EDs varied by patient age, race/ethnicity, and insurance status. The majority of patients were assigned ESI 3 in the academic and metropolitan community EDs (61% and 62%, respectively) whereas 47% were assigned ESI 3 in the rural community ED. In adjusted analyses, White females were less likely to be assigned ESI 1–2 compared to White males although both groups were roughly comparable in the assignment of ESI 4–5. Non-White and Hispanic females were generally least likely to be assigned ESI 1–2 in all EDs. Interactions between ED wait time and race/ethnicity-sex were not statistically significant. ConclusionsThis retrospective study of adult ED patients revealed sex and race/ethnicity-based differences in ESI assignment, after accounting for age, clinical factors, and ED operating conditions. These disparities persisted across three different large EDs, highlighting the need for ongoing research to address inequities in ED triage decision-making and associated patient-centered outcomes.

Adherence to recommended guidelines for low back pain presentations to an Australian emergency department: Barriers and enablers

ObjectiveThis study sought to evaluate the adherence to guidelines for the management of mechanical Low Back Pain within a single tertiary metropolitan Emergency Department setting. Our objectives were:1.To identify the proportion of patients presenting to a single Emergency Department with mechanical Low Back Pain who received management in line with the guidelines; and2.To understand and describe factors that can influence clinicians’ (non-) adherence to the guidelines. MethodsA two-stage multi-methods study design was undertaken. Stage 1 involved a retrospective chart audit of patients presenting with a diagnosis of mechanical Low Back Pain to establish documented adherence to clinical guidelines. Stage 2 explored clinicians’ perspectives towards factors influencing adherence to the guidelines via a study-specific survey and follow up focus groups. ResultsThe audit demonstrated low adherence to the following guidelines: (i) appropriate prescription of analgesia, (ii) targeted education and advice, and (iii) attempts to mobilise. Three major themes were identified as factors influencing adherence to the guidelines: (1) clinician driven influences and factors, (2) workflow processes, and (3) patient expectations and behaviours. ConclusionThere was low adherence to some published guidelines and factors influencing adherence to the guidelines were multi-factorial. Understanding the factors that influence care decisions and developing strategies to address these can improve Emergency Department management of mechanical Low Back Pain.

Characteristics of analytically confirmed gamma-hydroxybutyrate (GHB) positive patients in the emergency department: presentation, poly-drug use, disposition and impact on intensive care resource utilisation

Background Gamma-hydroxybutyrate is a potent central nervous system depressant with a narrow recreational dose window and analytical detection time. We describe data relating to intoxicated patients presenting to emergency departments across metropolitan Adelaide who tested positive for gamma-hydroxybutyrate. This work was part of the Emergency Department Admission Blood Psychoactive Testing study. Methods Over a 15-month period, patients presenting to four metropolitan emergency departments with symptoms of drug intoxication were enrolled in the study. The methodology involved the collection of demographic and clinical data and a de-identified blood sample which underwent comprehensive toxicological analysis. Gamma-hydroxybutyrate was determined using an acid-catalysed cyclisation followed by liquid-liquid extraction and gas chromatography-mass spectrometry. Data relating to samples positive for gamma-hydroxybutyrate were examined. Results and discussion A total of 1120 patients were enrolled between March 2019 and May 2020, 309 of whom were positive for gamma-hydroxybutyrate (27.6%). Of these, 256 (83%) were also positive for metamfetamine (methamphetamine). The most common clinical observation in gamma-hydroxybutyrate-positive patients was central nervous system depression (89%). There was a significant relationship between gamma-hydroxybutyrate status and sex; although males outnumbered females in absolute terms, a higher proportion of females (32%) tested positive for gamma-hydroxybutyrate than males (25%, P = 0.0155). Blood gamma-hydroxybutyrate concentrations ranged from 10 to 651 mg/L (0.096–6.2 mmol/L) and increasing gamma-hydroxybutyrate concentration correlated with severe toxicity. The presence of gamma-hydroxybutyrate had a significant impact on the patient discharge destination: the majority (69.2%) of gamma-hydroxybutyrate-positive patients were managed and discharged from the emergency department or their attached short stay wards. A significantly higher proportion of gamma-hydroxybutyrate-positive patients were admitted to the intensive care unit (28.2%) compared with gamma-hydroxybutyrate-negative patients (12.7%, chi-squared = 36.85, P <0 .001). Gamma-hydroxybutyrate positive cases accounted for 45.8% of all study-related intensive care unit admissions. Conclusions Gamma-hydroxybutyrate is commonly detected in illicit drug-related emergency department presentations and is detected disproportionately in the patient cohort who require intensive care unit level care.

Characteristics of non‐urgent neonatal presentations to an Australian metropolitan emergency department

To determine characteristics and risk factors for non-urgent presentations (NUPs) (triage categories 4 and 5) in neonates to a Western Sydney metropolitan mixed adult emergency department (ED) and the effect of COVID-19 on presentations and admissions. A retrospective medical record study examined neonates (age <4 weeks) presenting to the ED between October 2019 and September 2020 and assessed risk factors for NUPs including the impact of COVID-19. Regression analysis was used to determine which risk factors were significant for NUPs to ED and whether there were any significant differences in urgency of presentations and admissions during the post-COVID-19 time (on/after 11th March 2020). From 277 presentations, 114 (41%) were non-urgent. After regression analysis, being a mother born overseas (odds ratio 2.15, 95% confidence interval 1.13-4.12, P = 0.02) was a significant risk factor and maternal age (odds ratio 0.98, 95% confidence interval 0.96-0.1.00, P = 0.02) was a significant protective factor for NUPs in the neonatal period. There were 54 (47%) NUPs pre-COVID-19 and 60 (53%) NUPs post-COVID (P = 0.70). There were similar presenting complaints and diagnoses compared to the literature. Mothers born overseas and younger maternal age were found to be significant risk factors for NUPs in the neonatal period. There was no apparent impact on presentations and admissions to ED during the COVID-19 period. Further studies are warranted to further evaluate risk factors for NUPs in the neonatal period and further elucidate the impact of COVID-19 on presentations and admissions, specifically in later waves of the virus.

Racial and Ethnic Disparities in Emergency Department Wait Times for Children: Analysis of a Nationally Representative Sample.

To evaluate the association of race and ethnicity with wait times for children in US emergency departments (ED). We performed a cross-sectional study of ED encounters of children (<18 years) from 2014 to 2019 using a multistage survey of nonfederal US ED encounters. Our primary variable of interest was composite race and ethnicity: non-Hispanic White (NHW), non-Hispanic Black, Hispanic, and all others. Our outcome was ED wait time in minutes. We evaluated the association between race and ethnicity and wait time in Weibull regression models that sequentially added variables of acuity, demographics, hospital factors, and region/urbanicity. We included 163,768,956 survey-weighted encounters. In univariable analysis, Hispanic children had a lower hazard ratio (HR) of progressing to evaluation (HR 0.84, 95% confidence interval [CI] 0.76-0.93) relative to NHW children, indicating longer ED wait times. This association persisted in serial multivariable models incorporating acuity, demographics, and hospital factors. This association was not observed when incorporating variables of hospital region and urbanicity (HR 0.91, 95% CI 0.83-1.00). In subgroup analysis, Hispanic ethnicity was associated with longer wait times in pediatric EDs (HR 0.76, 95% CI 0.63-0.92), non-metropolitan EDs (HR 0.75, 95% CI 0.64-0.89), and the Midwest region (HR 0.77, 95% CI 0.69-0.87). No differences in wait times were observed for children of Black race or other races. Hispanic children experienced longer ED wait times across serial multivariable models, with significant differences limited to pediatric, metropolitan, and Midwest EDs. These results highlight the presence of disparities in access to prompt emergency care for children.

Premature mortality 16 years after emergency department presentation among homeless and at risk of homelessness adults: a retrospective longitudinal cohort study.

People experiencing homelessness have an increased risk of mortality. The association between being at risk of homelessness and premature mortality is unclear. We aimed to determine all-cause and cause-specific mortality in patients who were homeless, at risk of homelessness (marginally housed), or housed. This retrospective longitudinal cohort study compared mortality patterns in adult patients identified in 2003/04 by linking data from an Australian metropolitan emergency department to national mortality data. We used Cox proportional hazards models to estimate associations between housing status and mortality. To address competing risks, cause-specific hazards were modelled and transformed into stacked cumulative incidence functions. Data from 6290 patients (homeless deceased = 382/1050, marginally housed deceased = 259/518, housed deceased = 1204/4722) found increased risk of mortality in homeless [hazard ratio (HR) = 4.0, 95% confidence interval (CI) = 2.0-3.3) and marginally housed (HR = 2.6, 95% CI = 3.4-4.8) patients. Homeless patients had an excess risk from external causes (HR = 6.1, 95% CI = 4.47-8.35), cardiovascular disease (HR = 4.9, 95% CI = 2.78-8.70) and cancer (HR = 1.5, 95% CI = 1.15-2.09). Marginally housed patients had increased risk from external causes (HR = 3.6, 95% CI = 2.36-5.40) and respiratory diseases (HR = 4.7, 95% CI = 1.82-12.05). Taking account of competing risk, marked inequality was observed, with homeless, marginally housed and housed patients having probabilities of death by 55 years of 0.2, 0.1 and 0.02, respectively. Mortality rates were elevated in patients who were homeless or at risk of homelessness. Increasing numbers of people are at risk of homelessness, and the effect of this on mortality is relatively unrecognized. Marginal housing may assuage some risk of premature mortality associated with homelessness; however, it is not equivalent to stable housing.

Real-world decision-making in the management of patients presenting with major bleeding on rivaroxaban: the Auckland regional experience.

Rivaroxaban is used increasingly as an oral anticoagulant; however, a specific reversal agent is not currently available in the Australasian setting. There is also variation across international consensus guidelines regarding advice on the management of bleeding. To review the real-world management of rivaroxaban-associated major bleeding across the public hospitals of New Zealand's largest city. A retrospective cohort analysis was performed of patients prescribed rivaroxaban who presented to four metropolitan hospital Emergency Departments between 1 August 2018 and 31 May 2021 with major bleeding as defined by the International Society on Thrombosis and Haemostasis. One hundred and twelve patients were identified, accounting for 115 major bleeding presentations. Upper gastrointestinal (34%) and intracranial (31%) bleeding sites were most common. Procedural intervention was required in 44% of patients. Haemostatic management involved tranexamic acid (TXA) in 26%, prothrombin complex concentrate (PCC) in 55% (dose range 1000-6000 IU or 10-65 IU/kg), vitamin K in 16% and fresh frozen plasma in 1%. Rivaroxaban was discontinued permanently following 56 (49%) events, switched to another anticoagulant in 24 (21%) and withheld in 30 (26%) from 2 days to 3 months (median 8.5 days). All-cause mortality at 90 days after bleeding was 17% (19 patients), and the incidence of combined venous and arterial thrombotic events was 10%. There is considerable heterogeneity in the acute clinical management of patients presenting with rivaroxaban-related major bleeding. The use of PCC and dosage administered is inconsistent. TXA was utilised in only approximately one-quarter of all cases. Evidence-based guidance for treating rivaroxaban-related bleeding would improve the management of these patients and potentially improve clinical outcomes.

Presentations to the emergency department with self-harm or suicidal behaviours: A role for digital mental health services?

Emergency Department (ED) is an important site for assessing people presenting with self-harm or suicidal behaviors. Digital mental health services (DMHS) offer evidence-based interventions for mental health issues, but are often under-utilised, and information about them is rarely provided in ED. This feasibility study explored whether offering information about a DMHS to individuals presenting to ED with self-harm/suicidal behaviors resulted in self-enrolment in DMHS interventions for anxiety, depression and/or chronic pain. Methods: all individuals aged 18+ presenting with self-harm/suicidal behaviors to a metropolitan ED were screened for symptoms of anxiety, depression and/or chronic pain. Those with these symptoms were invited to participate in a study investigating enrolment with a DMHS. Study participants were provided with information about DMHS and followed up at one month. Results: 260 individuals presented with self-harm/suicidal behaviors over the 6-month study period. Many reported low mood (73.5%, n = 191) anxiety (67.2%, n = 174) and/or chronic pain (18.5%, n = 48). Half of those eligible for DMHS agreed at point of ED discharge to be contacted about participation in the DMHS study (51.4%, n = 108). One-third of these participated in the study (35.2%, n = 38). Rates of past-month high-risk SB (65.8%, n = 25), depression (92.1%, n = 35), anxiety (78.9%, n = 30) and chronic pain (57.9%, n = 22) were very high. Of these, 39.5% (n = 15) self-enrolled with the DMHS; almost all (80.0%, n = 13) engaged with an online intervention. Conclusions: A subset of people presenting to emergency department with suicidal behaviors will engage with DMHS. Better understanding is needed of factors contributing to uptake of DMHS in this group.

Impact of the Canadian CT head rule supplemented by the original published minimum inclusion criteria to assist emergency department clinicians’ assessment of patients presenting post fall from residential aged care: a retrospective audit

BackgroundA large number of CT brain (CTB) scans are ordered in the ED for older patients with a confirmed or possible head strike but no ongoing symptoms of a head injury. This study aimed to evaluate the effect of the Canadian CT head rule supplemented by the original published minimum inclusion criteria to assist clinician assessment of the need for CTB following minimal trauma fall in patients presenting from residential aged care facilities to a major metropolitan emergency department (ED).MethodsThis study was conducted as a pre- and post-intervention retrospective audit. The intervention involved implementation of a decision support tool to help clinicians assess patients presenting to the ED following a fall. The tool integrated the Canadian CT Head Rule (CCHR) in conjunction with a simplified set of inclusion criteria to help clinicians define a minimum threshold for a “minor head injury”. Outcome data pertaining to CT brain ordering practices and results were compared over symmetrical 3-month time periods pre- and post-intervention in 2 consecutive years.ResultsThe study included 233 patients in the pre-intervention arm and 241 in the post-intervention arm. Baseline demographics and clinical characteristics were similar in both groups. There was a 20% reduction in the total number of CTB scans ordered following tool implementation, with 134 (57.0%) scans in the pre-intervention group and 90 (37.3%) in the post-intervention group (p < 0.01). The diagnostic yield in the pre- and post-intervention groups was 3.7 and 5.6% respectively (p = 0.52). No variation was observed in medical management between groups, and no patients in either group underwent neurosurgical intervention.ConclusionsUse of the CCHR supplemented by the original published minimum inclusion criteria appeared to safely reduce the number of CTB scans performed in residential aged care facility residents presenting to an ED after a fall, with no associated adverse outcomes. A larger study across multiple centres is required to determine widespread efficacy and safety of this tool.

Effect of a simplified billing form and the SARS-CoV-2 pandemic on compensable billings in an Australian metropolitan emergency department: An interrupted time series analysis.

ObjectiveTo evaluate the effect of a simplified billing form on billings recovery.MethodsAn interrupted time series analysis of weekly presentations and billings between 1 April 2019 and 14 June 2020.ResultsNotably, 3228 patients were included (2030 Overseas Visitor Agreement, 359 Transport Accident Commission and 839 Work Cover). There was a $208.34 (95% CI 155.44–261.23, P < 0.0001) increase in billings per episode, that is, 59% (95% CI 44–74, P < 0.0001), from a baseline of $351.75/episode. There was no significant change in the actual billing rate during the pandemic.ConclusionTotal billings did not change. Less patients were identified, but each generated 59% more billings.

Impact of fine particulate matter (PM2.5) smoke during the 2019 / 2020 Australian bushfire disaster on emergency department patient presentations

The aim of this paper was to describe the patient characteristics and outcomes from a metropolitan emergency department (ED) during the 2019/2020 ‘Black Summer Bushfires’ disaster in Australia and compare the patient characteristics and outcomes to a matched period from the same ED one year earlier. Years of drought, low relative humidity, high temperatures, and high forest fuel loads led to catastrophic fire conditions across Australia during 2019 and 2020. As a result; 33 people died, 3 billion animals and 24 to 40 million hectares were lost, and 3,000 homes were destroyed. The impact of wildfire smoke is emerging in the literature regarding an exacerbation of respiratory, cardiac and cardiovascular disease. However, the impact on Australian EDs is minimally reported in the literature. This retrospective cross-sectional cohort study used routinely collected data from the ED patient information system from one metropolitan Australian ED. Data were obtained for patient presentations during the 2019/2020 Black Summer Bushfire period and a matched period, 2018/2019, one year earlier. Daily mean air quality indicators (PM 2.5 , PM 10 ) were obtained from the nearest air quality monitoring station. Data analysis included descriptive statistics, correlation coefficient and inferential statistics. Statistical significance was set at p ≤ 0.05. The 2019/2020 study period had a statistically significantly higher airborne particulate matter (PM 2.5 ) when compared to the matched period (p=<0.001), with comparable presentations between the study periods. However, an increase in respiratory related presentations (p<0.001; χ 2 = 34.31) was noted in the 2019/2020 period, with a positive correlation between daily increasing mean air quality (PM 2.5 , PM 10 ) and increasing patient presentations with respiratory related illness (p<0.001). Proportionately, patient demographics; mode of arrival, triage category, length of stay and admissions did not differ between periods. However, there was an increase in the raw number of patients being admitted to hospital with respiratory related illnesses, with a statistically significantly longer stay in the ED when compared to those discharged home (p<0.001). Wildfires produce smoke and subsequently poor air quality. The 2019/2020 Black Summer wildfire disaster in Australia resulted in an increase in respiratory-related patient presentations to the ED. Targeted public warning systems could be implemented in an attempt to limit an individual's exposure to wildfire smoke. Further, health services should monitor air quality as a predictor of patient presentations and subsequent health service demand, in support of ED preparedness.

‘The Chronicle of Nightmares’: Emergency Nurses’ Frontstage and Backstage Communication in the Emergency Department

ABSTRACT Effective emergency nurse-patient (EN) communication and ENs’ communication with other healthcare workers have implications for patient outcomes. Effective EN-patient communication informs and empowers patients. This study sought to better understand ENs frontstage and backstage interactions in a metropolitan emergency department (ED). The researcher engaged in participant observation of 15 different ENs’ healthcare interactions with patients and other healthcare workers in the ED for a total of 47 hours and 30 minutes. Iterative analysis of field notes builds reveal two key observations. First, frontstage and backstage spaces are fluid in nature, where healthcare workers simultaneously engage in backstage and frontstage communication regardless of physical space or audience. Second, frontstage communication processes can be categorized into three groups: information seeking and sharing, informally attending to patients and rapport building, and acting out of character. Further, a novel type of front stage interaction, “acting out of character” is conceptualized as when ENs act in ways that are inconsistent with their typical role when communicating with a patient. Implications for health communication practice and theorizing are discussed.

Documentation of paediatric head injuries in a mixed metropolitan emergency department.

Head injuries are a common presentation of children to Australian EDs. Healthcare documentation is an important tool for enhancing patient care. In our study, we aimed to assess the adequacy of paediatric head injury documentation in a mixed ED. A retrospective analysis of presentations to a mixed ED between 2017 and 2018. Children aged <16 years old with a primary diagnosis of head injury were included. Documentation items based on local head injury guidelines were assessed in both medical and nursing documentation. We compared cases aged <1 and ≥1year. There were 427 presentations that met the case definition. Medical documentation was present in 422 cases and nursing documentation in 310 cases. In combined medical and nursing documentation, items poorly documented include blood pressure (BP; 21.3%) and secondary survey (16.9%). In solely medical documentation, least commonly documented items are high-risk bony injuries (22.5%), high-risk soft tissue injuries (22.3%), seizure (22.0%) and non-accidental injury (3.6%). Glasgow Coma Scale (GCS) was poorly documented in cases aged <1year (10.9%, P < 0.001). The largest gaps in the documentation of paediatric head injuries were BP and paediatric GCS in infants. Future audits and educational strategies should focus on targeting clinically relevant items that are predictive of serious outcomes.

Low back pain presentations to rural, regional, and metropolitan emergency departments.

ObjectiveTo describe the context of low back pain (LBP) presentations to emergency departments (EDs) by remoteness areas, hospital delineation level and staffing portfolios.DesignA retrospective observational study using routinely captured ED and admission data over a 5‐year period (July 2014–June 2019).SettingsThirty seven EDs across a large health district in NSW, Australia, covering major cities, inner regional areas and outer regional areas.ParticipantsEmergency department (ED) presentations with a principal or secondary diagnosis of LBP based on ICD‐10 code (M54.5).Main outcome measuresED presentation and associated admission measures, including presentation rate, referral source, time in ED, re‐presentation rate, admission details and cost to the health system.ResultsThere were 26 509 ED presentations for LBP across the 5 years. Time spent in ED was 206 min for EDs in major cities, 146 min for inner regional EDs and 89 min for outer regional EDs. Re‐presentation rates were 6% in major cities, 8.8% in inner regional EDs and 11.8% in outer regional EDs. Admission rates were 20.4%, 15.8% and 18.8%, respectively.ConclusionsThis study describes LBP presentations across 37 EDs, highlighting the potential burden these presentations place on hospitals. LBP presentations appear to follow different pathways depending on the ED remoteness area, delineation level and staff portfolio.

Evaluation of a calcium, magnesium and phosphate clinical ordering tool in the emergency department.

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). We undertook a retrospective observational study in a single metropolitan ED. Patients aged 18years 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 (>0.2mmol/l above or below the laboratory reference range). 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>0.2mmol/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. 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.

Impact of COVID-19 pandemic on ophthalmic presentations to an Australian outer metropolitan and rural emergency department: a retrospective comparative study

BackgroundTo analyse ophthalmic presentations to an outer metropolitan and a rural emergency department (ED) during the first wave of the COVID-19 pandemic in New South Wales (NSW), Australia.MethodsA retrospective comparative study of ophthalmic emergency presentations to Campbelltown Hospital (fifth busiest NSW metropolitan ED; population 310,000) and Bowral and District Hospital (rural ED; population 48,000) before and during COVID-19 was conducted. Patient demographics, triage category, referral source, diagnosis, length of stay, departure status, and follow-up location were assessed from coding data between March 1st to May 31st in 2019 and 2020, corresponding to the peak case numbers and restrictions during the first wave of the COVID-19 pandemic in NSW. Differences before and during COVID-19 were analysed using chi-squared tests or independent sample t-tests.ResultsThere was no change in ophthalmic presentations at Campbelltown (n = 228 in 2019 vs. n = 232 in 2020; + 1.75%, p = 0.12) and an increase at Bowral (n = 100 in 2019 vs. n = 111 in 2020; + 11%, p < 0.01) during COVID-19. Urgent ophthalmic presentations (Triage Category 3) decreased at Bowral (p = 0.0075), while non-urgent ophthalmic presentations (Triage Category 5) increased at both hospitals (Campbelltown p < 0.05, Bowral p < 0.01).ConclusionsThere was no change in the total number of ophthalmic presentations to an outer metropolitan and an increase to a rural ED during the first wave of the COVID-19 pandemic in New South Wales, Australia. A change in the type of ophthalmic presentations at these peripheral EDs suggest that a high demand for ophthalmic services remained despite the pandemic and its associated gathering and movement restrictions. A flexible healthcare delivery strategy, such as tele-ophthalmology, may optimise patient care during and after COVID-19.
