Protocol for a cluster randomised controlled feasibility study of Prehospital Optimal Shock Energy for Defibrillation (POSED).

Aims: The Prehospital Optimal Shock Energy for Defibrillation (POSED) study will assess the feasibility of conducting a cluster randomised controlled study of clinical effectiveness in UK ambulance services to identify the optimal shock energy for defibrillation. Methods: POSED is a pragmatic, allocation concealed, open label, cluster randomised, controlled feasibility study. Defibrillators within a single UK ambulance service will be randomised in an equal ratio to deliver one of three shock strategies 120-150-200 J, 150-200-200 J, 200-200-200 J. Consecutive adults (≥18 years) presenting with out of hospital cardiac arrest requiring defibrillation will be eligible. The study plans to enrol 90 patients (30 in each group). Patients (or their relatives for non-survivors) will be informed about trial participation after the initial emergency has resolved. Survivors will be invited to consent to participate in follow-up (i.e., at 30 days or discharge).The primary feasibility outcome is the proportion of eligible patients who receive the randomised study intervention. Secondary feasibility outcomes will include recruitment rate, adherence to allocated treatment and data completeness. Clinical outcomes will include Return of an Organised Rhythm (ROOR) at 2 minutes post-shock, refibrillation rate, Return of Spontaneous Circulation (ROSC) at hospital handover, survival and neurological outcome at 30 days. Conclusion: The POSED study will assess the feasibility of a large-scale trial and explore opportunities to optimise the trial protocol.Trial registration: ISRCTN16327029.

The prognostic value of national early warning scores (NEWS) during transfer of care from community settings to hospital: a retrospective service evaluation.

BACKGROUND: The National Early Warning Score (NEWS) calculated from physiological observations provides a simple away to identify and respond to the deteriorating patient. There is increasing interest in the application of NEWS to facilitate referrals from the community. AIM: To establish whether elevated NEWS are associated with adverse outcomes at 5 and 30 days when obtained in a community setting at the time of transfer to an acute setting. DESIGN & SETTING: A retrospective service evaluation was undertaken using a database of emergency admissions to secondary care from two NHS district general hospitals within the South of England between January 2018 and April 2019. METHOD: The performance of NEWS recorded in a community setting to predict death or critical care admission at 5 and 30 days was calculated using established thresholds. RESULTS: 2786 referrals from primary care were analysed. The 5 day and 30 day mortality was 2.2% (1.7 to 2.8) and 7.1% (6.2 to 8.1). The prevalence of the composite outcome was 3.4% (2.8 to 4.2) at 5 days and 8.5% (7.5 to 9.6) at 30 days. The risk of adverse outcomes increased incrementally with increasing NEWS. When calculated at the point of referral from primary care the positive predictive value of death at 5 and 30 days was 15% (95% confidence intervals [CI] = 12 to 19) and 23% (95% CI = 17 to 30) in the high-risk NEWS group. CONCLUSION: Elevated NEWS obtained in the community during the process of emergency admission are associated with adverse outcomes. Communicating NEWS may allow downstream care to be better calibrated to risk.

Quality of the handover of patient care: a comparison of pre-Hospital and Emergency Department notes.

AIM: The aim of this audit was to evaluate the accuracy of patient information transfer from pre-hospital reports to Emergency Department (ED) documentation. METHODS: The records of 100 patients seen in the ED resuscitation room of a UK hospital were compared using a pro-forma designed by the research team. Sections of the ambulance service patient report form and the ED documentation were compared for differences. The history of the event leading to the 999 call, the patient's previous medical history, prescribed medications, allergies and any treatment carried out by the ambulance crew were analysed. RESULTS: Of the 100 records, 26 had at least one instance where information recorded by the ambulance crew was either omitted or altered during transfer. These fell into various categories including the previous medical history of the patient, the timings of the event bringing them to hospital, frequency of the event occurring, allergies and medications. CONCLUSION: This audit quantifies the number of patient encounters where written information changes or is lost when care is passed from pre-hospital to hospital staff in the resuscitation room. We have not investigated other parts of the ED or the verbal transfer of information. Further work investigating the causes of these changes in information, any impact on patient care and whether this occurs in other parts of an ED is suggested.

Offering assistance at road traffic incidents while off duty.

Every year in the UK road traffic incidents cause 320,000 injuries--40,000 of which are serious--and over 3,200 deaths. The public, patients and relatives expect nurses to be able to assist and provide first aid at the scene of any emergency. As a healthcare professional you should therefore ensure you are up to date with first aid skills.

Learning from the past to inform the future--a survey of consultant nurses in emergency care.

This paper reports the findings of a survey of UK consultant nurses in emergency care. The purpose of the survey was to elicit information regarding level of preparation for the consultant nurse role, the use of formal competency frameworks, current clinical scope of practice and perspectives on future preparation for the role. A semi-structured questionnaire was e-mailed to consultant nurses in emergency care. Respondents had an average of only 2 years in post and for 24% of respondents this was their second post as a consultant nurse. The survey identified that three quarters of the respondents had no specific preparation for the consultant nurse role. The remainder had varying levels of preparation ranging from brief induction to 6-month clinical training. It could be argued that this diversity of preparation is a reflection of the lack of clarity regarding the consultant nurse role and the ill-defined organisational frameworks within which some consultant nurse posts were established. With the exception of the expert practice domain and clinical leadership, the majority of respondents felt under prepared for one or more elements of the consultant nurse role. Clinically their scope of practice ranged from managing patients with minor illness or injury, to leading resuscitation teams. There was great inequity in the level of preparation for the role, particularly in the transformational leadership, education and training, and practice and service development domains. Strategies for addressing these deficiencies are identified.
