Predictors of care home resident conveyance to hospital or referral to community pathways by a regional ambulance service attending medical emergencies: a retrospective cross sectional study.

Background: Care home residents are at higher risk compared with community dwelling elders for medical emergencies, often resulting in ambulance attendance and conveyance to hospital. We aimed to determine the factors predicting care home resident conveyance to hospital or referral to community pathways by an ambulance service.

Methods: We used a retrospective cross-sectional study design analysing routine data from electronic clinical records from East Midlands Ambulance Service NHS Trust (EMAS).

A Randomized Trial of Drug Route in Out-of-Hospital Cardiac Arrest.

Background: In patients with out-of-hospital cardiac arrest, the effectiveness of drugs such as epinephrine is highly time-dependent. An intraosseous route of drug administration may enable more rapid drug administration than an intravenous route; however, its effect on clinical outcomes is uncertain.

Methods: We conducted a multicenter, open-label, randomized trial across 11 emergency medical systems in the United Kingdom that involved adults in cardiac arrest for whom vascular access for drug administration was needed.

improving Pain mAnagement for childreN and young people attendeD by Ambulance (PANDA): protocol for a realist review.

Background: Each year in England, 450,000 children and young people (CYP) under 18 years of age are transported by ambulance to emergency departments. Approximately 20% of these suffer acute pain caused by illness or injury. Pain is a highly complex sensory and emotional experience.

Paediatric out-of-hospital clinical deterioration: a mixed-methods scoping review protocol.

Introduction: In pre-hospital settings, identifying a deteriorating child can be challenging, especially considering that the proportion of paediatric patients with acute illnesses is lower compared with adults. This challenge is exacerbated in pre-hospital settings, where information might be scarce. Physiological alterations indicating changes in a patient's condition can be detected hours preceding a cardiac arrest.

Sex differences in the pre-hospital ambulance delay, assessment and treatment of patients with acute coronary syndrome: a rapid evidence review.

Background: Chest pain is a frequent symptom suffered by adult patients attended by ambulance. Evidence suggests female patients may suffer different symptoms to their male counterparts, potentiating differences in pre-hospital time delays, assessment and treatment.

Objective: To explore the sex differences in the pre-hospital ambulance delay, assessment and treatment of patients with acute coronary syndrome (ACS).

Route of drug administration in out-of-hospital cardiac arrest: A protocol for a randomised controlled trial (PARAMEDIC-3).

Aims: The PARAMEDIC-3 trial evaluates the clinical and cost-effectiveness of an intraosseous first strategy, compared with an intravenous first strategy, for drug administration in adults who have sustained an out-of-hospital cardiac arrest.

Methods: PARAMEDIC-3 is a pragmatic, allocation concealed, open-label, multi-centre, superiority randomised controlled trial. It will recruit 15,000 patients across English and Welsh ambulance services.

Development of indicators for avoidable emergency medical service calls by mapping paramedic clinical impression codes to ambulatory care sensitive conditions and mental health conditions in the UK and Canada.

Objective: Paramedic assessment data have not been used for research on avoidable calls. Paramedic impression codes are designated by paramedics on responding to a 911/999 medical emergency after an assessment of the presenting condition. Ambulatory care sensitive conditions (ACSCs) are non-acute health conditions not needing hospital admission when properly managed.

What are ambulance personnel experiences of sexual harassment and sexual assault in the workplace? A rapid evidence review.

Introduction: Sexual assault and harassment of ambulance personnel in the workplace is widespread. Prevention via body worn cameras and legal efforts have been positive, however improvement is still needed to ensure the protection of staff from the negative impact of sexual violence at work.

Methods: A rapid evidence review was conducted following the Cochrane Rapid Review guidance.

Angiogenic markers and maternal echocardiographic indices in women with hypertensive disorders of pregnancy.

Objective: The maternal cardiovascular system of women with hypertensive disorders of pregnancy (HDP) can be impaired, with higher rates of left ventricular (LV) remodeling and diastolic dysfunction compared to those with normotensive pregnancy. The primary objective of this prospective study was to correlate cardiac indices obtained by transthoracic echocardiography (TTE) and circulating angiogenic markers, such as soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF).

Methods: In this study, 95 women with a pregnancy complicated by HDP and a group of 25 with an uncomplicated pregnancy at term underwent TTE and blood tests to measure sFlt-1 and PlGF during the peripartum period (before delivery or within a week of giving birth).

A pre-hospital mixed methods systematic review protocol.

Introduction: Mixed methods research, a methodology entailing the integration of qualitative and quantitative data within a single study, offers researchers the ability to investigate complex processes and systems in health and healthcare. The collective strength gained through the data combination can provide an enhanced understanding of research problems, providing an ideal solution to understanding complex clinical issues in a range of settings. In pre-hospital practice, where often uncontrollable variables and environmental considerations increase healthcare complexity, mixed methods has emerged as a valuable approach to research.

Patient, family member, and ambulance staff experiences of prehospital acute pain management in adults: A systematic review and meta-synthesis.

Background: We aimed to synthesize the qualitative experiences of patients, their family members, and ambulance staff involved in the prehospital management of acute pain in adults and generate recommendations to improve the quality of care.

Methods: A systematic review was conducted following the enhancing transparency in reporting the synthesis of qualitative research (ENTREQ) guidelines. We searched from inception to June 2021: MEDLINE, CINAHL Complete, PsycINFO and Web of Science (search alerts were screened up to December 2021).

The reality of advanced airway management during out of hospital cardiac arrest; why did paramedics deviate from their allocated airway management strategy during the AIRWAYS-2 randomised trial?

Background: AIRWAYS-2 was a large multi-centre cluster randomised controlled trial investigating the effect on functional outcome of a supraglottic airway device (i-gel) versus tracheal intubation (TI) as the initial advanced airway during out-of-hospital cardiac arrest. We aimed to understand why paramedics deviated from their allocated airway management algorithm during AIRWAYS-2.

Methods: This study employed a pragmatic sequential explanatory design utilising retrospective study data collected during the AIRWAYS-2 trial.

Improving ambulance care for children suffering acute pain: a qualitative interview study.

Background: Pain is a highly complex sensory and emotional experience. When a child suffers acute pain through illness or injury, they are often transported to hospital by ambulance. Pre-hospital pain management in children is poor, with 61% of children receiving suboptimal pain management.

Ambulance attendance for substance and/or alcohol use in a pandemic: Interrupted time series analysis of incidents.

Introduction: The ambulance attendance for substance and/or alcohol use in a pandemic (ASAP) study explores incidents during the COVID-19 lockdown in the East Midlands region of the United Kingdom (23 March-4 July 2020).

Alcohol and other substance use during the COVID-19 pandemic: A systematic review.

Background: Although evidence suggests substance and alcohol use may change during the Covid-19 pandemic there has been no full review of the evidence around this.

Methods: A systematic review of all available evidence was carried out to document and interpret the frequency and severity of alcohol and other substance use during the Covid-19 pandemic and their relationship to demographic and mental health variables that may suggest further clinical implications. Peer reviewed articles in MEDLINE, Embase, PsycINFO, CINAHL complete and Sociological Abstracts were searched from December 2019 until November 2020.

Stanniocalcin-1 in the female reproductive system and pregnancy.

Background: Stanniocalcin-1 (STC-1) is a widely expressed glycoprotein hormone involved in a diverse spectrum of physiological and pathophysiological processes including angiogenesis, mineral homeostasis, cell proliferation, inflammation and apoptosis. Over the last 20 years, numerous studies have reported STC-1 expression within female reproductive tissues including the uterus, ovaries and placenta and implicated STC-1 in processes such as ovarian follicular development, blastocyst implantation, vascular remodelling in early pregnancy and placental development. Notably, dysregulation of STC-1 within reproductive tissues has been linked to the onset of severe reproductive disorders including endometriosis, polycystic ovary syndrome, poor trophoblast invasion and placental perfusion in early pregnancy.

Ambulance clinician perspectives of disparity in prehospital child pain management: A mixed methods study.

Background: When children suffer acute pain, the ambulance service is often involved to provide initial assessment, treatment, and transport. Several predictors of effective pain management have been identified, including children who are younger (0-5 years), administered analgesics, and living in homes from more affluent areas.

Objective: To explain previously identified predictors of effective prehospital pain management in children.

Mixed methods in pre-hospital research: understanding complex clinical problems.

Healthcare is becoming increasingly complex. The pre-hospital setting is no exception, especially when considering the unpredictable environment. To address complex clinical problems and improve quality of care for patients, researchers need to use innovative methods to create the necessary depth and breadth of knowledge.

Unexpected shock in a fallen older adult: a case report.

Introduction: Falls are common in older adults and frequently require ambulance service assistance. They are the most frequent cause of injury and associated morbidity and mortality in older adults. In recent years, the typical major trauma patient has changed from being young and male to being older in age, with falls of < 2 metres being the most common mechanism of injury.

The predictors, barriers and facilitators to effective management of acute pain in children by emergency medical services: A systematic mixed studies review.

We aimed to identify predictors, barriers and facilitators to effective pre-hospital pain management in children. A segregated systematic mixed studies review was performed. We searched from inception to 30-June-2020: MEDLINE, CINAHL Complete, PsycINFO, EMBASE, Web of Science Core Collection and Scopus.

Regulation of stanniocalcin-1 secretion by BeWo cells and first trimester human placental tissue from normal pregnancies and those at increased risk of developing preeclampsia.

Stanniocalcin-1 (STC-1) is a multi-functional glycosylated peptide present in the plasma of healthy women postpartum and increased further in pregnancies complicated by preeclampsia. Although the STC-1 gene is expressed by the placenta what regulates its secretion and from which cells at the feto-maternal interface is unknown. Here, we demonstrate for the first time that the syncytiotrophoblast and cytotrophoblast are a major site of STC-1 protein expression in first trimester placental tissue.

The phenotype of decidual CD56+ lymphocytes is influenced by secreted factors from decidual stromal cells but not macrophages in the first trimester of pregnancy.

During the first trimester of pregnancy the decidua is comprised of decidual stromal cells (DSC), invading fetal trophoblast cells and maternal leukocytes, including decidual natural killer (dNK) cells and macrophages. dNK cells are distinct from peripheral blood NK cells and have a role in regulating trophoblast invasion and spiral artery remodelling. The unique phenotype of dNK cells results from the decidual environment in which they reside, however the interaction and influence of other cells in the decidua on dNK phenotype is unknown.
