Qualitative study of new doctor induction and socialisation.

AIM: Junior doctors joining EDs are required to rapidly acquire new knowledge and skills, but there is little research describing how this process can be facilitated. We aimed to understand what would make ED formal induction and early socialisation more effective. METHODS: Qualitative study; informal interviews of junior doctors, consultants and nursing staff and direct observation of clinical interactions, induction and training in a single ED in an English Emergency Department between August and October 2018. We used constant comparison to identify and develop themes. FINDINGS: New junior doctors identified that early socialisation should facilitate patient safety and a safe learning space, with much of this process dependent on consultant interactions rather than formal induction. Clear themes around helpful and unhelpful consultant support and supervision were identified. Consultants who acknowledged their own fallibility and maintained approachability produced a safe learning environment, while consultants who lacked interest in their juniors, publicly humiliated them or disregarded the junior doctors' suggestions were seen as unhelpful and unconstructive. CONCLUSION: Effective socialisation, consistent with previous literature, was identified as critical. Junior doctors see consultant behaviours and interactions as key to creating a safe learning space.

Cessation of Smoking Trial in the Emergency Department (COSTED): a multicentre randomised controlled trial.

BACKGROUND: Supporting people to quit smoking is one of the most powerful interventions to improve health. The Emergency Department (ED) represents a potentially valuable opportunity to deliver a smoking cessation intervention if it is sufficiently resourced. The objective of this trial was to determine whether an opportunistic ED-based smoking cessation intervention can help people to quit smoking. METHODS: In this multicentre, parallel-group, randomised controlled superiority trial conducted between January and August 2022, adults who smoked daily and attended one of six UK EDs were randomised to intervention (brief advice, e-cigarette starter kit and referral to stop smoking services) or control (written information on stop smoking services). The primary outcome was biochemically validated abstinence at 6 months. RESULTS: An intention-to-treat analysis included 972 of 1443 people screened for inclusion (484 in the intervention group, 488 in the control group). Of 975 participants randomised, 3 were subsequently excluded, 17 withdrew and 287 were lost to follow-up. The 6-month biochemically-verified abstinence rate was 7.2% in the intervention group and 4.1% in the control group (relative risk 1.76; 95% CI 1.03 to 3.01; p=0.038). Self-reported 7-day abstinence at 6 months was 23.3% in the intervention group and 12.9% in the control group (relative risk 1.80; 95% CI 1.36 to 2.38; p<0.001). No serious adverse events related to taking part in the trial were reported. CONCLUSIONS: An opportunistic smoking cessation intervention comprising brief advice, an e-cigarette starter kit and referral to stop smoking services is effective for sustained smoking abstinence with few reported adverse events. TRIAL REGISTRATION NUMBER: NCT04854616.

Effect of removing the 4-hour access standard in the ED: a retrospective observational study.

BACKGROUND: Time-based targets are used to improve patient flow and quality of care within EDs. While previous research often highlighted the benefits of these targets, some studies found negative consequences of their implementation. We study the consequences of removing the 4-hour access standard. METHODS: We conducted a before and after, retrospective, observational study using anonymised, routinely collected, patient-level data from a single English NHS ED between April 2018 and December 2019. The primary outcomes of interest were the proportion of admitted patients, that is, the admission rate, the length of stay in the ED and ambulance handover times. We used interrupted time series models to study and estimate the impact of removing the 4-hour access standard. RESULTS: A total of 169 916 attendances were included in the analysis. The interrupted time series models for the average daily admission rate indicate a drop from an estimated 35% to an estimated 31% (95% CI -4.1 to -3.9). This drop is only statistically significant for Majors (Ambulant) patients (from an estimated 38.3% to an estimated 31.4%) and, particularly, for short-stay admissions (from an estimated 18.1% to an estimated 12.8%). The models also show an increase in the average daily length of stay for admitted patients from an estimated 316 min to an estimated 387 min (95% CI 33.5 to 108.9), and an increase in the average daily length of stay for discharged patients from an estimated 222 min to an estimated 262 min (95% CI 6.9 to 40.4). CONCLUSION: Lifting the 4-hour access standard reporting was associated with a drop in short-stay admissions to the hospital. However, it was also associated with an increase in the average length of stay in the ED. Our study also suggests that the removal of the 4-hour standard does not impact all patients equally. While certain patient groups such as those Majors (Ambulant) patients with less severe issues might have benefited from the removal of the 4-hour access standard by avoiding short-stay hospital admissions, the average length of stay in the ED seemed to have increased across all groups, particularly for older and admitted patients.

Cessation of smoking trial in the emergency department (CoSTED): protocol for a multicentre randomised controlled trial.

INTRODUCTION: Attendees of emergency departments (EDs) have a higher than expected prevalence of smoking. ED attendance may be a good opportunity to prompt positive behaviour change, even for smokers not currently motivated to quit. This study aims to determine whether an opportunist smoking cessation intervention delivered in the ED can help daily smokers attending the ED quit smoking and is cost-effective. METHODS AND ANALYSIS: A two-arm pragmatic, multicentred, parallel-group, individually randomised, controlled superiority trial with an internal pilot, economic evaluation and mixed methods process evaluation. The trial will compare ED-based brief smoking cessation advice, including provision of an e-cigarette and referral to local stop smoking services (intervention) with the provision of contact details for local stop smoking services (control). Target sample size is 972, recruiting across 6 National Health Service EDs in England and Scotland. Outcomes will be collected at 1, 3 and 6 months. The primary outcome at 6 months is carbon monoxide verified continuous smoking abstinence. ETHICS AND DISSEMINATION: The trial was approved by the South Central-Oxford B Research Committee (21/SC/0288). Dissemination will include the publication of outcomes, and the process and economic evaluations in peer-reviewed journals. The findings will also be appropriately disseminated to relevant practice, policy and patient representative groups. TRIAL REGISTRATION NUMBER: NCT04854616; protocol V.4.2.

Systematic Review of the Effectiveness of Advocacy Interventions for Adult Victims of Domestic Violence Within an Emergency Department Setting.

Advocacy interventions for survivors of domestic violence are well established and supported by evidence in some community and healthcare settings. Survivors of domestic violence identified in emergency departments have important differences, and it is not clear whether evidence can be applied to this population. We conducted an inclusive systematic review of controlled studies evaluating the effectiveness of advocacy workers for adult survivors identified in emergency departments. We identified five studies, all with substantial methodological flaws. The outcome measures were very varied. No study reported harm from advocacy. Most reported benefits from referrals to advocacy workers. Despite weak evidence, referral to advocacy workers for survivors of domestic violence is not harmful and offers benefits.

Evaluating the Sensitivity and Specificity of Siemens Clinitest Lateral Flow Test and the Simple AMplification-Based Assay (SAMBA)-2 PCR Test for SARS-CoV-2 Infection.

Introduction Accurate point-of-care testing for SARS-CoV-2 could quickly identify which patients need to be isolated and improve flow for patients being admitted as an emergency to the hospital. We evaluated two diagnostic tests with shorter turnaround times, the Siemens Clinitest Lateral Flow (Siemens Healthineers AG, Erlangen, Germany) and the Simple AMplification-Based Assay (SAMBA)-2 PCR test against a standard laboratory PCR test. Methods We conducted a prospective diagnostic cohort study in a single English emergency department. Adult participants underwent three swabs: the Siemens Clinitest Lateral Flow Test, the SAMBA-2 and a standard laboratory PCR test. Results A total of 212 participants were recruited. The sensitivity and specificity of the Siemens Clinitest Lateral Flow Test against the laboratory PCR test was 55.6% (95% CI 30.8-78.5) and 100% (95% CI 98.1-100) respectively. The sensitivity and specificity of the SAMBA-2 PCR test against the laboratory PCR test was 60.0% (95% CI 32.3-83.7) and 100% (95% CI 97.9-100) respectively. Conclusion Neither the Siemens Clinitest Lateral Flow Test nor the SAMBA-2 PCR test demonstrated sufficient sensitivity to rule out active SARS-CoV-2 infection. Both tests demonstrated high specificity.

A Qualitative Study: What Do Nurses in Charge in Emergency Departments Do?

Background The nurse-in-charge (NIC) role has been implemented in many emergency departments (EDs) to assist with smooth operations and coordination across the ED, together with the emergency physician in charge (EPIC). This work aims to describe the problem-solving approaches used by NICs and the coordination of their role with other team members. Methods Observations and semi-structured interviews were performed with NICs in a single centre, where NICs were purposively sampled for a variety of experience levels. During the observations, field notes were taken for every action conducted by the NIC in ED; the semi-structured interviews involved a combination of question prompts and a blank diagram of the ED that the NICs were asked to annotate. Constant comparative analysis based on grounded theory methodology was used for this qualitative study.  Results Eight different problem-solving approaches were identified. These are placing, targeting, guiding, juggling, chasing, team-leading, escalating and de-escalating. The last three were exclusive to NICs, whereas the others were shared to some degree with the EPIC. Seven team situational awareness processes used by NICs for coordination with other team members were identified, leading to a discussion on team synchronisation and shared awareness mechanisms. In particular, shared internal models amongst the NICs and also other team members provide a framework for analysing how team members function together in a healthcare setting.  Conclusions Emergency department NICs have a number of problem-solving approaches that have been defined and shown to have a degree of overlap with the emergency physician in charge. Shared awareness between the NIC and other ED team members facilitate decision-making and smooth coordination. These findings provide a better understanding of the role of the NIC and are useful for describing solutions for patient flow.

The Attend Study: A Retrospective Observational Study of Emergency Department Attendances During the Early Stages of the COVID-19 Pandemic.

INTRODUCTION: The coronavirus disease-19 (COVID-19) pandemic was associated with a large reduction in the number of attendances at emergency departments (EDs) in March 2020 in the United Kingdom (UK). We sought to identify which patient groups attended EDs least. METHODS: Single-centre before and after study. We used routine administrative data from March 2020 and compared this to a composite control of March 2019 and February 2020.  Results: Mean daily attendance fell by 30% from 342 patients per day in the composite control months to 242 patients per day in March 2020. Reductions in attendance were seen in almost all patient groups but were greatest in patients with injuries, those referred by another clinician, those arriving at the weekend, and in patients who received no investigations. Multivariate analysis revealed that the proportion of patients who were admitted to hospital fell, despite the patients being sicker, older, needing more investigations, and more likely to arrive by ambulance. DISCUSSION: The reduction in ED attendances seen in the early phases of the UK pandemic occurred in all patient groups, but was greatest in the lower acuity patients. Reasons for this are complex and likely to be multifactorial.

Are ED-based violence intervention programmes effective in reducing revictimisation and perpetration in victims of violence? A systematic review.

OBJECTIVES: Community violence bears significant human and economic costs. Furthermore, victims requiring ED treatment are at a greater risk of violent reinjury, arrest due to perpetration and violent death. We aimed to evaluate the effectiveness of ED-based violence intervention programmes (EVIPs), which aim to reduce future violence involvement in these individuals. METHODS: We performed a systematic literature review searching MEDLINE, Embase, Cumulative Index of Nursing and Allied Health Literature, PsycINFO, The Cochrane Library and Web of Science, in addition to hand-searching. Randomised controlled trials (RCTs) were included if they enrolled victims of community violence requiring ED treatment, evaluated interventions taking place in the ED and used violent revictimisation, arrests or intermediate outcome measures as endpoints. We included trials that had a Jadad score of 2 or above. RESULTS: 297 records were identified, and 13 articles were included in our final qualitative analysis, representing 10 RCTs and 9 different EVIPs. The risk of selection bias was low; the risk of performance, detection and attrition bias was moderate. 9 out of 13 papers reported statistically significant improvements in one or more outcome measures related to violence, including violent reinjury and arrests due to violence perpetration. CONCLUSION: The results of this literature review show that EVIPs may be capable of reducing violent reinjury and arrests due to violence perpetration. Larger RCTs, taking place in different regions, in different age groups and using different techniques, are justified to determine which conditions may be required for success and whether EVIPs are generalisable.

Is seniority of emergency physician associated with the weekend mortality effect? An exploratory analysis of electronic health records in the UK.

OBJECTIVE: Admission to hospital over a weekend is associated with increased mortality, but the underlying causes of the weekend effect are poorly understood. We explore to what extent differences in emergency department (ED) admission and discharge processes, severity of illness and the seniority of the treating physician explain the weekend effect. METHODS: We analysed linked ED attendances to hospital admissions to Cambridge University Hospital over a 7-year period from 1 January 2007 to 31 December 2013, with 30-day in-hospital death as the primary outcome and discharge as a competing risk. The primary exposure was day of the week of arrival. Subdistribution hazards models controlled for multiple confounders, including physician seniority, calendar year, mode of arrival, triage category, referral from general practice, sex, arrival time, prior attendances and admissions, diagnosis group and age. RESULTS: 229 401 patients made 424 845 ED attendances, of which 158 396 (37.3%) were admitted to the hospital. The case-mix of admitted patients was more ill at weekends: 2530 (6.4%) admitted at a weekend required immediate resuscitation compared with 6450 (5.4%) admitted on a weekday (p<0.0001). Senior doctors admitted 24.8% of patients on weekdays and 24.0% at weekends, but junior doctors admitted 61.7% of patients on weekdays and 44.2% at weekends. 3947 (3.3%) patients admitted on a weekday and 1454 (3.7%) patients admitted at a weekend died within 30 days. In the adjusted subdistribution hazards model, the HR of in-hospital death was 1.11 (95% CI 1.04 to 1.18) for weekend arrivals. After controlling for confounders, the in-hospital mortality of patients admitted by junior doctors was greater at the weekend (adjusted HR (aHR) 1.15, 95% CI 1.06 to 1.24). In-hospital mortality for patients admitted by senior doctors was not statistically different at the weekend (aHR 1.08, 95% CI 0.98 to 1.19). CONCLUSIONS: Our findings suggest that the weekend effect was driven by a higher proportion of admitted patients requiring immediate resuscitation at the weekend. Junior doctors admitted a lower proportion of relatively healthy patients at the weekend compared with the weekday, thus diluting the risk pool of weekday admissions and contributing to the weekend effect. Senior doctors' admitting behaviour did not change at the weekend, and the corresponding weekend effect was reduced.

Changing epidemiology of assault victims in an emergency department participating in information sharing with police: a time series analysis.

INTRODUCTION: Violent injury places a large burden on the NHS. We had implemented information sharing in our ED in 2007 and aimed to see which patient groups were most affected by information sharing, as this would provide clues as to how this complex intervention works. METHODS: Retrospective time series study of all the assault victims presenting for ED care between 2005 and 2014 at a single ED in England. RESULTS: 10 328 patients presented during the study period. There was a 37% decrease in the number of patients presenting after assault, consistent with national trends. The proportions of people arriving by ambulance, and the proportion of men did not change during the study period. There were no important changes in the age of our assault patients in this study. Greater, disproportionate, decreases in rates of violence were seen in patients who presented at the weekend up (incidence rate ratio (IRR)=0.57, 95% CI 0.50 to 0.64) versus weekdays (IRR=0.72; 95% CI 0.62 to 0.83) There were also disproportionately greater decreases over the study period in patients who were discharged with no hospital follow-up (IRR=0.51, 95% CI 0.45 to 0.56) versus those leading to either an inpatient admission (IRR=1.05, 95% CI 0.84 to 1.31) or outpatient follow-up (IRR=1.23, 95% CI 0.93 to 1.64). CONCLUSIONS: The epidemiology of violent injury at our institution has changed over the last 10 years and is most marked in a reduction of visits at the weekend, and in those who leave without follow up.

Has the Licensing Act 2003 affected violence rates in England and Wales? A systematic review of hospital and police studies.

Violence has been declining in the UK for two decades, with most assaults being alcohol related. The Licensing Act 2003 (England and Wales) aimed to reduce alcohol-related crime, giving local authorities control over premises licensing. We performed a systematic review of original research with the primary outcome of change in violence rates since the Act's implementation, including hospital-defined and police-defined measures of violence. Our secondary outcome was temporal distribution of violence. Fifteen studies were included, which were of overall poor quality. Seven found reduced violence rates after the Act's implementation, three found increased rates and five found no significant change. A subset of nine studies analysed temporal distribution, eight finding displacement of incidents later. This is the most complete analysis to date of the effect of this Act on violence, finding a lack of reliable evidence to answer the research question, but little to suggest that the Act has markedly impacted already-declining violence rates.

The burden of sepsis in the Emergency Department: an observational snapshot.

The primary aim of our study was to establish what proportion of patients in the Emergency Department (ED) fulfill the criteria for sepsis. All adult patients presenting to ED in two 1-week periods, 6 months apart, were included. Notes were reviewed retrospectively to identify which patients fulfilled the criteria for sepsis and severe sepsis. The proportion of patients with sepsis was 4.3% (95% confidence interval 3.3-5.2%) and the proportion with severe sepsis was 2.2% (95% confidence interval 1.5-2.8%). In conclusion our results suggest that sepsis is more common than previously reported and this represents a significant burden on ED.
