Ethnicity and outcomes for patients with gastrointestinal disorders attending an emergency department serving a multi-ethnic populationBackground: Ethnic inequalities in acute health acute care are not well researched. We examined how attendee ethnicity influenced outcomes of emergency care in unselected patients presenting with a gastrointestinal (GI) disorder. Methods: A descriptive, retrospective cohort analysis of anonymised patient level data for University Hospitals of Leicester emergency department attendees, from 1 January 2018 to 31 December 2021, receiving a diagnosis of a GI disorder was performed. The primary exposure of interest was self-reported ethnicity, and the two outcomes studied were admission to hospital and whether patients underwent clinical investigations. Confounding variables including sex and age, deprivation index and illness acuity were adjusted for in the analysis. Chi-squared and Kruskal-Wallis tests were used to examine ethnic differences across outcome measures and covariates. Multivariable logistic regression was used to examine associations between ethnicity and outcome measures. Results: Of 34,337 individuals, median age 43 years, identified as attending the ED with a GI disorder, 68.6% were White. Minority ethnic patients were significantly younger than White patients. Multiple emergency department attendance rates were similar for all ethnicities (overall 18.3%). White patients had the highest median number of investigations (6, IQR 3-7), whereas those from mixed ethnic groups had the lowest (2, IQR 0-6). After adjustment for age, sex, year of attendance, index of multiple deprivation and illness acuity, all ethnic minority groups remained significantly less likely to be investigated for their presenting illness compared to White patients (Asian: aOR 0.80, 95% CI 0.74-0.87; Black: 0.67, 95% CI 0.58-0.79; mixed: 0.71, 95% CI 0.59-0.86; other: 0.79, 95% CI 0.67-0.93; p < 0.0001 for all). Similarly, after adjustment, minority ethnic attendees were also significantly less likely to be admitted to hospital (Asian: aOR 0.63, 95% CI 0.60-0.67; Black: 0.60, 95% CI 0.54-0.68; mixed: 0.60, 95% CI 0.51-0.71; other: 0.61, 95% CI 0.54-0.69; p < 0.0001 for all). Conclusions: Significant differences in usage patterns and disparities in acute care outcomes for patients of different ethnicities with GI disorders were observed in this study. These differences persisted after adjustment both for confounders and for measures of deprivation and illness acuity and indicate that minority ethnic individuals are less likely to be investigated or admitted to hospital than White patients.

Management of adults with bacterial meningitis in the Emergency DepartmentIntroduction: The Leicester Royal Infirmary Emergency Department is one of the largest single-site Emergency Departments in the UK. We evaluated the department's management of bacterial meningitis. The current national guideline recommends that all patients presenting with suspected bacterial meningitis receive antibiotics within one hour. Methods: A survey of 100 clinicians (Consultants, Registrars, House Officers, and Advanced Clinical Practitioners) working in the Emergency Department was performed to determine the awareness of the guidelines and a retrospective examination of case notes for patients who presented at the Leicester Royal Infirmary Emergency Department with suspected meningitis was carried out between May 1, 2022, and May 1, 2023. A random sample of 30 patients was drawn from the department's database of 190 patients, identified through discharge coding summaries. Results: Nine (25%) of the prescribers knew of the guidelines for managing meningitis, and six (16.7%) had utilised the hospital guidelines. Thirty-three (91.7%) prescribers acknowledged the importance of administering steroids to patients suspected of having bacterial meningitis (excluding those displaying signs of meningococcal sepsis, such as a rash). However, only seven (23%) of patients received this treatment. Additionally, only one (3.3%) patient was documented as having received a dose within the first hour of presentation. Conclusion: The timely diagnosis and administration of appropriate antibiotic therapy are pivotal elements in managing bacterial meningitis. As a result, we designed a checklist to facilitate the effective management of meningitis within the department by increasing awareness of the guidelines and making the critical principles of suspected meningitis management more accessible.

Quality metrics for same day emergency care-Consensus of a multi-professional panel of experts using a modified Delphi processSame Day Emergency Care (SDEC) services are at the heart of recovery plans for Emergency Care in the National Health Service. There are no validated metrics for the quality of care in SDEC. The Society for Acute Medicine's Quality Improvement Committee invited to a three-stage modified Delphi process to gather metrics used by clinicians. Proposed metrics were ranked and further explored by 33 participating experts from a broad range of backgrounds including clinicians, data scientists and operational managers. Experts ranked five system-based metrics highest. These focus on optimisation of the proportion of patients receiving same day care in and out of SDEC units. Patient and staff experience metrics were ranked low, possibly due to present lack of viable examples. The paper adds a glossary with the rationale for ranking of metrics and their use for the improvement of quality and safety of clinical care.

The paradox of haemodialysis: the lived experience of the clocked treatment of chronic illnessStudies exploring the relationship between time and chronic illness have generally focused on measurable aspects of time, also known as linear time. Linear time follows a predictable, sequential order of past, present and future; measured using a clock and predicated on normative assumptions. Sociological concepts addressing lifecourse disruption following diagnosis of chronic illness have served to enhance the understanding of lived experience. To understand the nuanced relationship between time and chronic illness, however, requires further exploration. Here, we show how the implicit assumptions of linear time meet in tension with the lived experience of chronic illness. We draw on interviews and photovoice work with people with end-stage kidney disease in receipt of in-centre-daytime haemodialysis to show how the clocked treatment of chronic illness disrupts experiences of time. Drawing on concepts of 'crip' and 'chronic' time we argue that clocked treatment and the lived experience of chronic illness converge at a paradox whereby clocked treatment allows for the continuation of linear time yet limits freedom. We use the concept of 'crip time' to challenge the normative assumptions implicit within linear concepts of time and argue that the understanding of chronic illness and its treatment would benefit from a 'cripped' starting point.

Emergency department discharge practices for children with acute wheeze and asthma: a survey of discharge practice and review of safety netting instructions in the UK and IrelandObjective: Recovery from acute wheeze and asthma attacks should be supported with safety netting, including treatment advice. We evaluated emergency department (ED) discharge practices for acute childhood wheeze/asthma attacks to describe variation in safety netting and recovery bronchodilator dosing. Design: Two-phase study between June 2020 and September 2021, comprising (1) Departmental discharge practice survey, and (2) Analysis of written discharge instructions for caregivers. Setting: Secondary and tertiary EDs in rural and urban settings, from Paediatric Emergency Research in the UK and Ireland (PERUKI). Main outcome measures: Describe practice and variation in discharge advice, treatment recommendations and safety netting provision. Results: Of 66/71 (93%) participating sites, 62/66 (93.9%) reported providing written safety netting information. 52/66 (78.8%) 'nearly always' assessed inhaler/spacer technique; routine medication review (21/66; 31.8%) and adherence (16/66; 21.4%) were less frequent. In phase II, 61/66 (92.4%) submitted their discharge documents; 50/66 (81.9%) included bronchodilator plans. 11/66 (18.0%) provided Personalised Asthma Action Plans as sole discharge information. 45/50 (90%) provided 'fixed' bronchodilator dosing regimes; dose tapering was common (38/50; 76.0%). Median starting dose was 10 puffs 4 hourly (27/50, 54.0%); median duration was 4 days (29/50, 58.0%). 13/61 (21.3%) did not provide bronchodilator advice for acute deterioration; where provided, 42/48 (87.5%) recommended 10 puffs immediately. Subsequent dosages varied considerably. Common red flags included inability to speak (52/61, 85.2%), inhalers not lasting 4 hours (51/61, 83.6%) and respiratory distress (49/61, 80.3%). Conclusions: There is variation in bronchodilator dosing and safety netting content for recovery following acute wheeze and asthma attacks. This reflects a lack of evidence, affirming need for further multicentre studies regarding bronchodilator recovery strategies and optimal safety netting advice.

High-flow humidified oxygen as an early intervention in children with acute severe asthma: protocol for a feasibility randomized controlled trialBackground: Acute severe asthma (ASA) is a leading cause of hospital attendance in children. Standard first-line therapy consists of high-dose inhaled bronchodilators plus oral corticosteroids. Treatment for children who fail to respond to first-line therapy is problematic: the use of intravenous agents is inconsistent, and side effects are frequent. High-flow humidified oxygen (HiFlo) is widely used in respiratory conditions and is increasingly being used in ASA, but with little evidence for its effectiveness. A well-designed, adequately powered randomized controlled trial (RCT) of HiFlo therapy in ASA is urgently needed, and feasibility data are required to plan such an RCT. In this study, we describe the protocol for a feasibility study designed to fill this knowledge gap. Objective: This study aims to establish whether a full RCT of early HiFlo therapy in children with ASA can be conducted successfully and safely, to establish whether recruitment using deferred consent is practicable, and to define appropriate outcome measures and sample sizes for a definitive RCT. The underlying hypothesis is that early HiFlo therapy in ASA will reduce the need for more invasive treatments, allow faster recovery and discharge from hospital, and in both these ways reduce distress to children and their families. Methods: We conducted a feasibility RCT with deferred consent to assess the use of early HiFlo therapy in children aged 2 to 11 years with acute severe wheeze not responding to burst therapy (ie, high-dose inhaled salbutamol with or without ipratropium). Children with a Preschool Respiratory Assessment Measure score ≥5 after burst therapy were randomized to commence HiFlo therapy or follow standard care. The candidate primary outcomes assessed were treatment failure requiring escalation and time to meet hospital discharge criteria. Patient and parent experiences were also assessed using questionnaires and telephone interviews. Results: The trial was opened to recruitment in February 2020 but was paused for 15 months owing to the COVID-19 pandemic. The trial was reopened at the lead site in July 2021 and opened at the other 3 sites from August to December 2022. Recruitment was completed in June 2023. Conclusions: This feasibility RCT of early HiFlo therapy in children with ASA recruited to the target despite major disturbances owing to the COVID-19 pandemic. The data are currently being analyzed and will be published separately.

Prevalence of invasive bacterial infection in febrile infants ≤90 days with a COVID-19 positive test: a systematic review and meta-analysisBackground: Febrile infants with an infection by influenza or enterovirus are at low risk of invasive bacterial infection (IBI). Objective: To determine the prevalence of IBI among febrile infants ≤90 days old with a positive COVID-19 test. Methods: MEDLINE, Embase, Cochrane Central Register databases, Web of Science, ClinicalTrials.gov and grey literature were searched for articles published from February 2020 to May 2023. Inclusion criteria: researches reporting on infants ≤90 days of age with fever and a positive test for SARS-CoV-2 (antigen test/PCR). Case reports with <3 patients, articles written in a language other than English, French or Spanish, editorials and other narrative studies were excluded. Preferred Reposting Items for Systematic Reviews and Meta-analysis guidelines were followed, and the National Institutes of Health Quality Assessment Tool was used to assess study quality. The main outcome was the prevalence of IBI (a pathogen bacterium identified in blood and/or cerebrospinal fluid (CSF)). Forest plots of prevalence estimates were constructed for each study. Heterogeneity was assessed and data were pooled by meta-analysis using a random effects model. A fixed continuity correction of 0.01 was added when a study had zero events. Results: From the 1023 studies and 3 databases provided by the literature search, 33 were included in the meta-analysis, reporting 3943 febrile infants with a COVID-19 positive test and blood or CSF culture obtained. The pooled prevalence of IBI was 0.14% (95% CI, 0.02% to 0.27%). By age, the prevalence of IBI was 0.56% (95% CI, 0.0% to 1.27%) in those 0-21 days old, 0.53% (95% CI, 0.0% to 1.22%) in those 22-28 days old and 0.11% (95% CI, 0.0% to 0.24%) in those 29-60 days old. Conclusion: COVID-19-positive febrile infants ≤90 days old are at low risk of IBI, especially infants >28 days old, suggesting this subgroup of patients can be managed without blood tests.

Point-of-care ultrasound is a useful adjunct tool to a clinician's assessment in the evaluation of severe hyponatraemiaIntroduction: Hyponatraemia is the most common electrolyte disorder in inpatients resulting mainly from an imbalance in water homeostasis. Intravascular fluid status assessment is pivotal but is often challenging given multimorbidity, polypharmacy and diuretics use. We evaluated the utility of point-of-care ultrasound (POCUS) as an adjunct tool to standard practice for fluid assessment in severe hyponatraemia patients. Methods: Patients presenting with severe hyponatremia (Serum Sodium [Na] < 120 mmol/L; Normal range: 135-145 mol/L), managed by standard care were included. Hyponatraemia biochemistry work-up and POCUS examination were undertaken. Both clinician and POCUS independently assigned one of the three fluid status groups of hypovolaemia, hypervolaemia or euvolaemia. The final diagnosis of three fluid status groups at admission was made at the time of discharge by retrospective case review. Clinician's (standard of care) and POCUS fluid assessments were compared to that of the final diagnosis at the time of discharge. Results: n = 19 patients were included. Median Na on admission was 113 mmol/L (109-116), improved to 129 ± 3 mmol/L on discharge. POCUS showed the higher degree of agreement with the final diagnosis (84%; n = 16/19), followed by the clinician (63%; n = 12/19). A trend towards higher accuracy of POCUS compared to clinician assessment of fluid status was noted (84% vs. 63%, p = 0.1611). Biochemistry was unreliable in 58% (n = 11/19) likely due to renal failure, polypharmacy or diuretic use. Inappropriate emergency fluid management was undertaken in 37% (n = 7/19) of cases based on initial clinician assessment. Thirst symptom correlated to hypovolaemia in 80% (4/5) cases. Conclusion: As subjective clinical and biochemistry assessments of fluid status are often unreliable due to co-morbidities and concurrent use of medications, POCUS can be a rapid objective diagnostic tool to assess fluid status in patients with severe hyponatraemia, to guide accurate emergency fluid management.

The effect of relative hypotension on 30-day mortality in older people receiving emergency careResearch has observed increased mortality among older people attending the emergency department (ED) who had systolic pressure > 7 mmHg lower than baseline primary care values. This study aimed to (1) assess feasibility of identifying this 'relative hypotension' using readily available ED data, (2) externally validate the 7 mmHg threshold, and (3) refine a threshold for clinically important relative hypotension. A single-centre retrospective cohort study linked year 2019 data for ED attendances by people aged over 64 to hospital discharge vital signs within the previous 18 months. Frailty and comorbidity scores were calculated. Previous discharge ('baseline') vital signs were subtracted from initial ED values to give individuals' relative change. Cox regression analysis compared relative hypotension > 7 mmHg with mean time to mortality censored at 30 days. The relative hypotension threshold was refined using a fully adjusted risk tool formed of logistic regression models. Receiver operating characteristics were compared to NEWS2 models with and without incorporation of relative systolic. 5136 (16%) of 32,548 ED attendances were linkable with recent discharge vital signs. Relative hypotension > 7 mmHg was associated with increased 30-day mortality (HR 1.98; 95% CI 1.66-2.35). The adjusted risk tool (AUC: 0.69; sensitivity: 0.61; specificity: 0.68) estimated each 1 mmHg relative hypotension to increase 30-day mortality by 2% (OR 1.02; 95% CI 1.02-1.02). 30-day mortality prediction was marginally better with NEWS2 (AUC: 0.73; sensitivity: 0.59; specificity: 0.78) and NEWS2 + relative systolic (AUC: 0.74; sensitivity: 0.63; specificity: 0.75). Comparison of ED vital signs with recent discharge observations was feasible for 16% individuals. The association of relative hypotension > 7 mmHg with 30-day mortality was externally validated. Indeed, any relative hypotension appeared to increase risk, but model characteristics were poor. These findings are limited to the context of older people with recent hospital admissions.

Core outcomes and factors influencing the experience of care for children with severe acute exacerbations of asthma: a qualitative studyObjective: To identify the outcomes considered important, and factors influencing the patient experience, for parents and caregivers of children presenting to hospital with a severe acute exacerbation of asthma. This work contributes to the outcome-identification process in developing a core outcome set (COS) for future clinical trials in children with severe acute asthma. Design: A qualitative study involving semistructured interviews with parents and caregivers of children who presented to hospital with a severe acute exacerbation of asthma. Setting: Hospitals in 12 countries associated with the global Pediatric Emergency Research Networks, including high-income and middle-income countries. Interviews were conducted face-to-face, by teleconference/video-call, or by phone. Findings: Overall, there were 54 interviews with parents and caregivers; 2 interviews also involved the child. Hospital length of stay, intensive care unit or high-dependency unit (HDU) admission, and treatment costs were highlighted as important outcomes influencing the patient and family experience. Other potential clinical trial outcomes included work of breathing, speed of recovery and side effects. In addition, the patient and family experience was impacted by decision-making leading up to seeking hospital care, transit to hospital, waiting times and the use of intravenous treatment. Satisfaction of care was related to communication with clinicians and frequent reassessment. Conclusions: This study provides insight into the outcomes that parents and caregivers believe to be the most important to be considered in the process of developing a COS for the treatment of acute severe exacerbations of asthma.

Clinical Frailty Scale at presentation to the emergency department: interrater reliability and use of algorithm-assisted assessmentPurpose: The Clinical Frailty Scale (CFS) allows health care providers to quickly stratify older patients, to support clinical decision-making. However, few studies have evaluated the CFS interrater reliability (IRR) in Emergency Departments (EDs), and the freely available smartphone application for CFS assessment was never tested for reliability. This study aimed to evaluate the interrater reliability of the Clinical Frailty Scale (CFS) ratings between experienced and unexperienced staff (ED clinicians and a study team (ST) of medical students supported by a smartphone application to assess the CFS), and to determine the feasibility of CFS assignment in patients aged 65 or older at triage. Methods: Cross-sectional study using consecutive sampling of ED patients aged 65 or older. We compared assessments by ED clinicians (Triage Clinicians (TC) and geriatric ED trained nurses (geriED-TN)) and a study team (ST) of medical students using a smartphone application for CFS scoring. The study is registered on Clinicaltrials.gov (NCT05400707). Results: We included 1349 patients aged 65 and older. Quadratic-weighted kappa values for ordinal CFS levels showed a good IRR between TC and ST (ϰ = 0.73, 95% CI 0.69-0.76), similarly to that between TC and geriED-TN (ϰ = 0.75, 95% CI 0.66-0.82) and between the ST and geriED-TN (ϰ = 0.74, 95% CI 0.63-0.81). A CFS rating was assigned to 972 (70.2%) patients at triage. Conclusion: We found good IRR in the assessment of frailty with the CFS in different ED providers and a team using a smartphone application to support rating. A CFS assessment occurred in more than two-thirds (70.2%) of patients at triage.

Sustaining interventions in care homes initiated by quality improvement projects: a qualitative studyIntroduction: Inadequate and varied quality of care in care homes has led to a proliferation of quality improvement (QI) projects. This study examined the sustainability of interventions initiated by such projects. Method: This qualitative study explored the sustainability of seven interventions initiated by three QI projects between 2016 and 2018 in UK care homes and explored the perceived influences to the sustainability of interventions. QI projects were followed up in 2019. Staff leading QI projects (n=9) and care home (n=21, from 13 care homes) and healthcare (n=2) staff took part in semi-structured interviews. Interventions were classified as sustained if the intervention was continued at the point of the study. Thematic analysis of interview data was performed, drawing on the Consolidated Framework for Sustainability (CFS), a 40-construct model of sustainability of interventions. Results: Three interventions were sustained and four interventions were not. Seven themes described perceptions around what influenced sustainability: monitoring outcomes and regular check-in; access to replacement intervention materials; staff willingness to dedicate time and effort towards interventions; continuity of staff and thorough handover/inductions in place for new staff; ongoing communication and awareness raising; perceived effectiveness; and addressing care home priorities. All study themes fell within 18 of the 40 CFS constructs. Discussion: Our findings resonate with the CFS and are also consistent with implementation theories, suggesting sustainability is best addressed during implementation rather than treated as a separate process which follows implementation. Commissioning and funding QI projects should address these considerations early on, during implementation.

Tailored psychological intervention for anxiety or depression in COPD (TANDEM): a randomised controlled trialThis multi-centre, pragmatic, randomised controlled trial evaluated whether a tailored psychological intervention based on a cognitive behavioural approach for people with COPD and symptoms of anxiety and/or depression improved anxiety or depression compared to usual care (UC).People with COPD and moderate to very severe airways obstruction and Hospital Anxiety and Depression Scale subscales scores indicating mild to moderate anxiety (HADS-A) and/or depression (HADS-D), were randomised 1.25:1, intervention (242): UC (181). Respiratory health professionals delivered the intervention face-to-face over 6-8 weeks. Co-primary outcomes were HADS-A and HADS-D measured six months post-randomisation. Secondary outcomes at six and 12 months included: HADS-A and HADS-D (12 months), Beck Depression Inventory II, Beck Anxiety Inventory, St George's Respiratory Questionnaire, social engagement, the EUROQOL instrument 5-level version, smoking status, completion of pulmonary rehabilitation (PR) and health and social care resource use.The intervention did not improve anxiety (HADS-A mean difference, 95% CI, -0.60, -1.40 to 0.21) or depression (HADS-D -0.66, -1.39 to 0.07) at six months. The intervention did not improve any secondary outcomes at either timepoint, nor did it influence completion of PR or healthcare resource use. Deaths in the intervention arm 13/242 (5%) exceeded those in the control arm 3/181 (2%), but none were associated with the intervention. Health economic analysis found the intervention highly unlikely to be cost-effective.This trial has shown, beyond reasonable doubt, that this cognitive behavioural intervention delivered by trained and supervised respiratory health professionals does not improve psychological comorbidity in people with advanced COPD and depression or anxiety.

Gallstone ileus: Clinical presentation and radiological diagnosisThe term "gallstone ileus" refers to intestinal obstruction brought on by a gallstone lodged within its lumen. The gallstone travels through a fistula that develops because of the constant pressure it exerts on the gall bladder. The symptoms are vague and confounding which can commonly lead to delay in diagnosis. The preferred imaging technique is a computed tomography scan. The diagnosis is confirmed by the identification of Rigler's Triad on a CT scan, which includes a small intestinal obstruction, pneumobilia, and an ectopic stone in the intestine. The condition is associated with several complications and needs to be treated with emergency surgery. This case demonstrates how a patient could have non-specific symptoms and how early detection by imaging was crucial to the patient's treatment.

Sedation and analgesia for reduction of pediatric ileocolic intussusceptionImportance: Ileocolic intussusception is an important cause of intestinal obstruction in children. Reduction of ileocolic intussusception using air or fluid enema is the standard of care. This likely distressing procedure is usually performed without sedation or analgesia, but practice variation exists. Objective: To characterize the prevalence of opioid analgesia and sedation and assess their association with intestinal perforation and failed reduction. Design, setting, and participants: This cross-sectional study reviewed medical records of children aged 4 to 48 months with attempted reduction of ileocolic intussusception at 86 pediatric tertiary care institutions in 14 countries from January 2017 to December 2019. Of 3555 eligible medical records, 352 were excluded, and 3203 medical records were eligible. Data were analyzed in August 2022. Exposures: Reduction of ileocolic intussusception. Main outcomes and measures: The primary outcomes were opioid analgesia within 120 minutes of reduction based on the therapeutic window of IV morphine and sedation immediately before reduction of intussusception. Results: We included 3203 patients (median [IQR] age, 17 [9-27] months; 2054 of 3203 [64.1%] males). Opioid use was documented in 395 of 3134 patients (12.6%), sedation 334 of 3161 patients (10.6%), and opioids plus sedation in 178 of 3134 patients (5.7%). Perforation was uncommon and occurred in 13 of 3203 patients (0.4%). In the unadjusted analysis, opioids plus sedation (odds ratio [OR], 5.92; 95% CI, 1.28-27.42; P = .02) and a greater number of reduction attempts (OR, 1.48; 95% CI, 1.03-2.11; P = .03) were significantly associated with perforation. In the adjusted analysis, neither of these covariates remained significant. Reductions were successful in 2700 of 3184 attempts (84.8%). In the unadjusted analysis, younger age, no pain assessment at triage, opioids, longer duration of symptoms, hydrostatic enema, and gastrointestinal anomaly were significantly associated with failed reduction. In the adjusted analysis, only younger age (OR, 1.05 per month; 95% CI, 1.03-1.06 per month; P < .001), shorter duration of symptoms (OR, 0.96 per hour; 95% CI, 0.94-0.99 per hour; P = .002), and gastrointestinal anomaly (OR, 6.50; 95% CI, 2.04-20.64; P = .002) remained significant. Conclusions and relevance: This cross-sectional study of pediatric ileocolic intussusception found that more than two-thirds of patients received neither analgesia nor sedation. Neither was associated with intestinal perforation or failed reduction, challenging the widespread practice of withholding analgesia and sedation for reduction of ileocolic intussusception in children.

Improving communications in PPE: a solution for 'landline' telephone communicationBackground: Emergency care staff wearing elastomeric respiratory personal protective equipment (PPE) report difficulties in communicating by telephone. We developed and tested an affordable technological solution aimed at improving telephone call intelligibility for staff wearing PPE. Methods: A novel headset was created to enable a throat microphone and bone conduction headset to be used in combination with a standard hospital 'emergency alert' telephone system. Speech intelligibility of an ED staff member wearing PPE was compared between the proposed headset and current practice by simultaneously recording a version of the Modified Rhyme Test and a Key Sentences Test. Recordings were played back to a group of blinded ED staff listening to pairs of recordings under identical conditions. The proportion of correctly identified words was compared using a paired t-test. Results: Fifteen ED staff correctly identified a mean of 73% (SD 9%) words for speech communicated via the throat microphone system, compared with only 43% (SD 11%) of words for standard practice (paired t-test, p<0.001). Conclusions: Introduction of a suitable headset could significantly improve speech intelligibility during 'emergency alert' telephone calls.
