BackgroundAntimicrobial stewardship programs attempting to optimize antibiotic therapy and clinical outcomes mainly focus on inpatient and outpatient settings. The lack of antimicrobial stewardship program studies in the emergency department (ED) represents a gap in tackling the problem of antimicrobial resistance as EDs treat a substantial number of upper respiratory tract infection cases throughout the year. ObjectiveWe intend to implement two evidence-based interventions: (1) patient education and (2) providing physician feedback on their prescribing rates. We will incorporate evidence from a literature review and contextualizing the interventions based on findings from a local qualitative study. MethodsOur study uses a quasi-experimental design to evaluate the effects of interventions over time in the EDs of 4 public hospitals in Singapore. We will include an initial control period of 18 months. In the next 6 months, we will randomize 2 EDs to receive 1 intervention (ie, patient education) and the other 2 EDs to receive the alternative intervention (ie, physician feedback). All EDs will receive the second intervention in the subsequent 6 months on top of the ongoing intervention. Data will be collected for another 6 months to assess the persistence of the intervention effects. The information leaflets will be handed to patients at the EDs before they consult with the physician, while feedback to individual physicians by senior doctors is in the form of electronic text messages. The feedback will contain the physicians’ antibiotic prescribing rate compared with the departments’ overall antibiotic prescribing rate and a bite-size message on good antibiotic prescribing practices. ResultsWe will analyze the data using segmented regression with difference-in-difference estimation to account for concurrent cluster comparisons. ConclusionsOur proposed study assesses the effectiveness of evidence-based, context-specific interventions to optimize antibiotic prescribing in EDs. These interventions are aligned with Singapore’s national effort to tackle antimicrobial resistance and can be scaled up if successful.

BackgroundThe uncertainties surrounding the COVID-19 pandemic led to a surge in non-urgent emergency department (ED) attendance among people presenting with upper respiratory tract infection (URTI) symptoms. These non-urgent visits, often manageable in primary care, exacerbated ED overcrowding, which could compromise the quality of ED services. Understanding patients' expectations and the reasons for these ED visits is imperative to mitigate the problem of ED overcrowding. Hence, we assessed the factors influencing patients' expectations for diagnostic tests during their ED visits for uncomplicated URTI during different phases of the pandemic.MethodsWe conducted a cross-sectional study on adults with URTI symptoms seeking care at four public EDs in Singapore between March 2021 and March 2022. We segmented the study period into three COVID-19 pandemic phases—containment, transition, and mitigation. The outcome variables are whether patients expected (1) a COVID-19-specific diagnostic test, (2) a non-COVID-19-specific diagnostic test, (3) both COVID-19-specific and non-COVID-19-specific diagnostic tests, or (4) no diagnostic test. We built a multinomial regression model with backward stepwise selection and classified the findings according to Andersen's healthcare utilization model.ResultsThe mean age of participants was 34.5 (12.7) years. Factors (adjusted odds ratio [95% confidence interval]) influencing expectations for a COVID-19-specific diagnostic test in the ED include younger age {21–40 years: (2.98 [1.04–8.55])}, no prior clinical consultation (2.10 [1.13–3.89]), adherence to employer's health policy (3.70 [1.79–7.67]), perceived non-severity of illness (2.50 [1.39–4.55]), being worried about contracting COVID-19 (2.29 [1.11–4.69]), and during the transition phase of the pandemic (2.29 [1.15–4.56]). Being non-employed influenced the expectation for non-COVID-19-specific diagnostic tests (3.83 [1.26–11.66]). Factors influencing expectations for both COVID-19-specific and non-COVID-19-specific tests include younger age {21–40 years: (3.61 [1.26–10.38]); 41–60 years: (4.49 [1.43–14.13])}, adherence to employer's health policy (2.94 [1.41–6.14]), being worried about contracting COVID-19 (2.95 [1.45– 5.99]), and during the transition (2.03 [1.02–4.06]) and mitigation (2.02 [1.03–3.97]) phases of the pandemic.ConclusionPatients' expectations for diagnostic tests during ED visits for uncomplicated URTI were dynamic across the COVID-19 pandemic phases. Expectations for COVID-19-specific diagnostic tests for ED visits for uncomplicated URTI were higher among younger individuals and those worried about contracting COVID-19 during the COVID-19 pandemic. Future studies are required to enhance public communications on the availability of diagnostic services in primary care and public education on self-management of emerging infectious diseases such as COVID-19.

Abstract Background Acute ischemic stroke is a time-sensitive emergency where accurate diagnosis is required promptly. Due to time pressures, stroke mimics who present with similar signs and symptoms as acute ischemic stroke, pose a diagnostic challenge to the emergency physician. With limited access to investigative tools, clinical prediction, tools based only on clinical features, may be useful to identify stroke mimics. We aim to externally validate the performance of 4 stroke mimic prediction scales, and derive a novel decision tree, to improve identification of stroke mimics. Methods We performed a retrospective cross-sectional study at a primary stroke centre, served by a telestroke hub. We included consecutive patients who were administered intravenous thrombolysis for suspected acute ischemic stroke from January 2015 to October 2017. Four stroke mimic prediction tools (FABS, simplified FABS, Telestroke Mimic Score and Khan Score) were rated simultaneously, using only clinical information prior to administration of thrombolysis. The final diagnosis was ascertained by an independent stroke neurologist. Area under receiver operating curve (AUROC) analysis was performed. A classification tree analysis was also conducted using variables which were found to be significant in the univariate analysis. Results Telestroke Mimic Score had the highest discrimination for stroke mimics among the 4 scores tested (AUROC = 0.75, 95% CI = 0.63–0.87). However, all 4 scores performed similarly (DeLong p > 0.05). Telestroke Mimic Score had the highest sensitivity (91.3%), while Khan score had the highest specificity (88.2%). All 4 scores had high positive predictive value (88.1 to 97.5%) and low negative predictive values (4.7 to 32.3%). A novel decision tree, using only age, presence of migraine and psychiatric history, had a higher prediction performance (AUROC = 0.80). Conclusion Four tested stroke mimic prediction scales performed similarly to identify stroke mimics in the emergency setting. A novel decision tree may improve the identification of stroke mimics.

Introduction: Supraventricular tachycardia (SVT) is commonly encountered in the emergency department (ED). Vagal manoeuvres are internationally recommended therapy in stable patients. The head down deep breathing (HDDB) technique was previously described as an acceptable vagal manoeuvre, but there are no studies comparing its efficacy to other vagal manoeuvres. Our objective in this study was to compare the rates of successful cardioversion with HDDB and the commonly practiced, modified Valsalva manoeuvre (VM). Methods: We conducted a randomised controlled trial at an acute hospital ED. Patients presenting with SVT were randomly assigned to HDDB or modified VM in a 1:1 ratio. A block randomisation sequence was prepared by an independent biostatistician, and then serially numbered, opaque, sealed envelopes were opened just before the intervention. Patients and caregivers were not blinded. Primary outcome was cardioversion to sinus rhythm. Secondary outcome(s) included adverse effects/complications of each technique. Results: A total of 41 patients were randomised between 1 August, 2018–1 February, 2020 (20 HDDB and 21 modified VM). Amongst the 41 patients, three spontaneously cardioverted to sinus rhythm before receiving the allocated treatment and were excluded. Cardioversion was achieved in six patients (31.6%) and seven patients (36.8%) with HDDB and modified VM, respectively (odds ratio 1.26, 95% confidence interval, 0.33, 4.84, P = 0.733). Seventeen (89.5%) patients in the HDDB group and 14 (73.7%) from the modified VM group did not encounter any adverse effects. No major adverse cardiovascular events were recorded. Conclusion: Both the head down deep breathing technique and the modified Valsalva manoeuvre appear safe and effective in cardioverting patients with SVT in the ED.

The article address the issue of crowding in accident and emergency (A&E) departments, where demand for emergency medical services exceeds available resources. It is reported that this overcrowding can negatively impact the quality of patient care, as well as affect the morale, productivity, and training of A&E staff. It further aims to emphasize the significance of understanding the causes of A&E crowding and identifying measures to alleviate the problem.

A 54-year- old woman with insulin-requiring type 2 diabetes mellitus presented with acute shortness of breath and drowsiness on a background of polydipsia, weakness and significant weight loss. One year ago, she had decided to stop her insulin and other medications and adopt lifestyle modifications instead. Initial emergency department (ED) blood samples were highly lipaemic and appeared strawberry pink. She was eventually diagnosed with diabetic ketoacidosis (DKA) with severe hypertriglyceridaemia, intubated for airway protection, and managed with fluid resuscitation and intravenous insulin to good effect. We share an uncommon DKA presentation at the ED. History was limited as the patient was drowsy and minimally communicative. Physical examination was unremarkable. Blood investigations were also delayed in view of the need for additional centrifugation. These contributed to a paucity of information in the acute setting and resulted in a diagnostic challenge.

From 29 June to 7 July 2009, Singapore hosted the inaugural Asian Youth Games (AYG), which brought 1210 athletes and 810 officials from 43 participating countries. On 11 June, just 1 week before the Games Village Medical Centre started operations, the World Health Organization officially declared a global H1N1 2009 pandemic. Working in close partnership with the Olympic Council of Asia Medical Commission, Singapore AYG Organising Committee and other government agencies, the AYG Medical Services Committee was successful in preventing the local transmission of H1N1, which would have been a threat to the games, as it could have led to the cancellation of these games. This article describes the experience and valuable lessons learnt from managing a sports-related mass gathering during the developing pandemic. [ABSTRACT FROM AUTHOR]

Background Emergency Department (ED) crowding is a global public health issue with low-acuity ED attendances (LAA) being widely identified as contributors to the issue. A primary care partnership programme, GPFirst, was developed to encourage low-acuity patients to visit their General Practitioners (GP) first, instead of the ED. We utilised a qualitative approach to gain an understanding of participants’ perceptions of GPFirst, their health-seeking behaviours, and explore recommendations for enhancing GPFirst. Methods A qualitative study design, underpinned by an interpretivist approach, was employed. Purposive sampling was used to recruit 12 GPFirst patients from a single tertiary care centre for semi-structured interviews. These interviews were analysed using Braun and Clarke’s reflexive thematic analysis. Results Participants’ age ranged from 25 to 63 years old. Four themes were identified. Firstly, “ perceptions of GPs” , described the variations in participants’ perceptions about GPs. Secondly, “patients’ expectations of GPFirst” , noted the ED fee subsidy and prioritisation of ED care as key expectations of GPFirst. Thirdly, “facilitators and barriers to utilising GPFirst” highlighted the facilitators and barriers that influenced participants’ health-seeking behaviours and finally “recommendations for programme improvement” offered strategies for improvements. Conclusion This is the first qualitative study to examine participants’ perceptions of GPFirst. Recommendations may inform future programme redesign to optimise patient experience and facilitate programme uptake, contributing to overall efforts to reduce ED crowding locally. Future research may consider exploring GPFirst providers’ perspectives to elicit facilitators and barriers in implementation.

OBJECTIVES: To evaluate the effectiveness of a pilot smoking cessation service in an emergency department (ED) clinical observation unit. STUDY DESIGN: A descriptive case series review was undertaken of smoking cessation service patients in the short-stay unit of an acute hospital in Singapore from July 1, 2018, to December 31, 2019. METHODS: Upon admission, ED nurses screen all patients regarding their current smoking status and implement the 5 A's framework, which involves the steps of Ask-Advise-Assess-Assist-Arrange. Patients in the "contemplation" and "preparation" stages were offered the following components: (1) a bedside counseling session by a pharmacist and (2) a follow-up appointment at an outpatient smoking cessation clinic. Postdischarge follow-up telephone calls at 1, 6, and 12 months were carried out as part of the study data collection to obtain abstinence information. RESULTS: Forty-seven patients were included in the study; the majority were male (n = 41; 87.2%). The median numbers of cigarettes smoked per day at baseline, 1 month, 6 months, and 12 months were 14, 5, 3, and 5, respectively. The overall point-prevalence abstinence rates over the same follow-up time points were 26.5%, 38.7%, and 31.3%, respectively. The proportions of patients lost to follow-up at 1 month, 6 months, and 12 months were 27.7%, 34.0%, and 31.9%, respectively. CONCLUSIONS: Given the small sample and high number of uncontactable patients, more research is needed to assess whether the trend toward increasing point-prevalence abstinence rate over time and the trend toward decreasing median number of cigarettes smoked are observed in a larger sample.
