Ambulance clinician use of capillary blood ketone meters to improve emergency hyperglycaemia care: A stepped-wedged controlled, mixed-methods feasibility study.

AIM: To determine whether it was feasible, safe and acceptable for ambulance clinicians to use capillary blood ketone meters for 'high-risk' diabetic ketoacidosis (DKA) recognition and fluid initiation, to inform the need for a full-powered, multi-centre trial. METHODS: Adopting a stepped-wedge controlled design, participants with hyperglycaemia (capillary blood glucose >11.0 mmol/L) or diabetes and unwell were recruited. 'High-risk' DKA intervention participants (capillary blood ketones ≥3.0 mmol/L) received paramedic-led fluid therapy. Participant demographic and clinical data were collated from ambulance and hospital care records. Twenty ambulance and Emergency Department clinicians were interviewed to understand their hyperglycaemia and DKA care experiences. RESULTS: In this study, 388 participants were recruited (Control: n = 203; Intervention: n = 185). Most presented with hyperglycaemia, and incidence of type 1 and type 2 diabetes was 18.5% and 74.3%, respectively. Ketone meter use facilitated 'high-risk' DKA identification (control: 2.5%, n = 5; intervention: 6.5%, n = 12) and was associated with improved hospital pre-alerting. Ambulance clinicians appeared to have a high index of suspicion for hospital-diagnosed DKA participants. One third (33.3%; n = 3) of Control and almost half (45.5%; n = 5) of Intervention DKA participants received pre-hospital fluid therapy. Key interview themes included clinical assessment, ambulance DKA fluid therapy, clinical handovers; decision support tool; hospital DKA management; barriers to hospital DKA care. CONCLUSIONS: Ambulance capillary blood ketone meter use was deemed feasible, safe and acceptable. Opportunities for improved clinical decision making, support and safety-netting, as well as in-hospital DKA care, were recognised. As participant recruitment was below progression threshold, it is recommended that future-related research considers alternative trial designs. CLINICALTRIALS: gov: NCT04940897.

A qualitative study on conveyance decision-making during emergency call outs to people with dementia: the HOMEWARD project.

BACKGROUND: Paramedics are increasingly required to make complex decisions as to whether they should convey a patient to hospital or manage their condition at the scene. Dementia can be a significant barrier to the assessment process. However, to our knowledge no research has specifically examined the process of decision-making by paramedics in relation to people with dementia. This qualitative study was designed to investigate the factors influencing the decision-making process during Emergency Medical Services (EMS) calls to older people with dementia who did not require immediate clinical treatment. METHODS: This qualitative study used a combination of observation, interview and document analysis to investigate the factors influencing the decision-making process during EMS calls to older people with dementia. A researcher worked alongside paramedics in the capacity of observer and recruited eligible patients to participate in case studies. Data were collected from observation notes of decision-making during the incident, patient care records and post incident interviews with participants, and analysed thematically. FINDINGS: Four main themes emerged from the data concerning the way that paramedics make conveyance decisions when called to people with dementia: 1) Physical condition; the key factor influencing paramedics' decision-making was the physical condition of the patient. 2) Cognitive capacity; most of the participants preferred not to remove patients with a diagnosis of dementia from surroundings familiar to them, unless they deemed it absolutely essential. 3) Patient circumstances; this included the patient's medical history and the support available to them. 4) Professional influences; participants also drew on other perspectives, such as advice from colleagues or information from the patient's General Practitioner, to inform their decision-making. CONCLUSION: The preference for avoiding unnecessary conveyance for patients with dementia, combined with difficulties in obtaining an accurate patient medical history and assessment, mean that decision-making can be particularly problematic for paramedics. Further research is needed to find reliable ways of assessing patients and accessing information to support conveyance decisions for EMS calls to people with dementia.

Ambulance staff and end-of-life hospital admissions: A qualitative interview study.

BACKGROUND: Hospital admissions for end-of-life patients, particularly those who die shortly after being admitted, are recognised to be an international policy problem. How patients come to be transferred to hospital for care, and the central role of decisions made by ambulance staff in facilitating transfer, are under-explored. AIM: To understand the role of ambulance staff in the admission to hospital of patients close to the end of life. DESIGN: Qualitative interviews, using particular patient cases as a basis for discussion, analysed thematically. PARTICIPANTS/SETTING: Ambulance staff ( n = 6) and other healthcare staff (total staff n = 30), involved in the transfer of patients (the case-patients) aged more than 65 years to a large English hospital who died within 3 days of admission with either cancer, chronic obstructive pulmonary disease or dementia. RESULTS: Ambulance interviewees were broadly positive about enabling people to die at home, provided they could be sure that they would not benefit from treatment available in hospital. Barriers for non-conveyance included difficulties arranging care particularly out-of-hours, limited available patient information and service emphasis on emergency care. CONCLUSION: Ambulance interviewees fulfilled an important role in the admission of end-of-life patients to hospital, frequently having to decide whether to leave a patient at home or to instigate transfer to hospital. Their difficulty in facilitating non-hospital care at the end of life challenges the negative view of near end-of-life hospital admissions as failures. Hospital provision was sought for dying patients in need of care which was inaccessible in the community.

Unplanned, urgent and emergency care: what are the roles that EMS plays in providing for older people with dementia? An integrative review of policy, professional recommendations and evidence.

OBJECTIVE: To synthesise the existing literature on the roles that emergency medical services (EMS) play in unplanned, urgent and emergency care for older people with dementia (OPWD), to define these roles, understand the strength of current research and to identify where the focus of future research should lie. DESIGN: An integrative review of the synthesised reports, briefings, professional recommendations and evidence. English-language articles were included if they made any reference to the role of EMS in the urgent or emergency care of OPWD. Preparatory scoping and qualitative work with frontline ambulance and primary care staff and carers of OPWD informed our review question and subsequent synthesis. RESULTS: Seventeen literature sources were included. Over half were from the grey literature. There was no research that directly addressed the review question. There was evidence in reports, briefings and professional recommendations of EMS addressing some of the issues they face in caring for OPWD. Three roles of EMS could be drawn out of the literature: emergency transport, assess and manage and a 'last resort' or safety net role. CONCLUSIONS: The use of EMS by OPWD is not well understood, although the literature reviewed demonstrated a concern for this group and awareness that services are not optimum. Research in dementia care should consider the role that EMS plays, particularly if considering crises, urgent care responses and transitions between care settings. EMS research into new ways of working, training or extended paramedical roles should consider specific needs and challenges of responding to people with dementia.

An in-depth qualitative interview study of female ambulance staff experiences of the menopause transition (CESSATION phase 3).

Introduction: Menopause is a key workplace issue. Many women will experience symptoms through their later working life. The ambulance service constitutes an employment setting that, dependent on the roles of female staff, can impact on the severity of menopause symptoms and experiences (Prothero et al., 2021). This study aimed to explore female ambulance staff experiences of the menopause transition and suggest ways to improve support offerings. Methods: A qualitative interpretive approach was adopted, involving 12 UK ambulance services. Participants were identified via purposive sampling, and semi-structured interviews were conducted from February to July 2022 via an online platform or telephone. Recordings were transcribed verbatim and analysed using an inductive thematic approach. Results: Twenty-two female participants, aged between 42 and 62 years, were interviewed, and represented all phases of the menopause: peri-menopause (n = 9); menopause (n = 5); post-menopause (n = 3); and unsure (n = 5). Fourteen participants had front-line (patient-facing) or emergency operation centre-based roles, while seven were employed in service support roles. Ten themes were identified: impact on work role; awareness and preparedness for menopause transition; personal impact of symptoms; desired support; appropriate sickness and menopause policy; managerial development; compassion and dignity; impact of working environment; impact on safety; and lack of choice. Lack of understanding and support from colleagues and line managers were identified as the key issues. This is included under the managerial development and compassion and dignity themes. Conclusions: The varying range of menopausal symptoms and their severity impacted on women's performance at work. The experience of working while going through the menopause could be challenging. Employers should adopt a menopause policy which includes training and awareness for all staff, and suitable for front-line as well as service support staff. There is a need to create a culture where the menopause is not taboo, and women feel able to talk about their symptoms.

'Very hit and miss': an interpretive phenomenological analysis of ambulance service care for young people experiencing mental health crisis.

Introduction: The ambulance service provides vital front line mental healthcare for young people in crisis, but there is a lack of evidence to guide best practice in this area. The lived experiences of service users can offer important insights to guide service development, therefore we carried out a qualitative evaluation of care provided by the ambulance service to young people experiencing a mental health-related emergency. Methods: Ten participants aged 16-25 years who had used the ambulance service due to a mental health crisis within the past 2 years were interviewed about their experiences and view of the care they received. Interviews were transcribed verbatim and interpretative phenomenological analysis used to explore participants' individual narratives and identify recurrent themes. Results: A theme of inconsistent quality of care was evident in all participants' accounts. Contributing to this superordinate theme were six recurrent themes: positive qualities of individual ambulance clinicians, ambivalence about seeking care, the importance of retaining agency, need for mental health training for ambulance clinicians, need for inter-service collaboration and favourable comparison of the ambulance service to other services. Conclusions: We identified some examples of good practice, including person-centred care, respect for patient autonomy and attending to physical health needs. However, our findings suggest the quality of ambulance service mental healthcare is not yet sufficiently consistent. In the absence of mandatory high-quality mental health training and evidence-based protocols, the quality of care appears largely dependent on the qualities and experience of individual ambulance clinicians.

Ambulance staff awareness of vitamin D and risk of deficiency in a UK ambulance service: a survey-based evaluation.

AIMS: The aim of this service evaluation was to explore staff awareness of vitamin D and the risks associated with deficiency in the ambulance setting, to inform the need for appropriate well-being support and resources. METHODS: An online, anonymous 20-question survey was purpose-designed, based on a validated vitamin D questionnaire. It was made available to staff for completion in one UK ambulance service between 16 June and 12 July 2020, resulting in a convenience sample of 354 responses. These were analysed using quantitative (descriptive) and qualitative (thematic) approaches. RESULTS: The cohort age range was 20 to 65+ years; 41% (n = 156) were male. Over half of respondents worked within emergency operational service delivery (57%; n = 219), but all key service roles were represented. Respondents reported to be predominantly 'White British' (92%; n = 352), but nine ethnic groups were included. According to the Fitzpatrick Scale, most staff described themselves as having a 'Medium, between white to moderate brown: sometimes mild burns, gradual tan' complexion (47%; n = 182) or 'White, Fair: usually burns, tans with difficulty' (32%; n = 124). The majority felt they got sufficient sunlight exposure when at home (66%; n = 253), but not at work (58%; n = 222). Typically, respondents stated they were 'neither unconcerned or concerned' about having vitamin D deficiency (35%; n = 135), although almost a fifth (17%; n = 66) reported to have been told they had vitamin D deficiency by a medical professional. Forty percent of respondents took vitamin D supplements: 12% (n = 45) as advised by a medical professional, and 28% (n = 107) self-directed to prevent vitamin D deficiency. Of the remaining, many (35%; n = 136) had not considered taking such dietary supplements. The ability of respondents to recognise known factors that affect vitamin D production in the skin, good vitamin D food sources and individuals at risk of vitamin D deficiency was variable. Additional comments raised by respondents related to lack of vitamin D awareness, the risk factors and impact of deficiency, vitamin supplementation, COVID-19, work arrangements and sunlight exposure, self-learning and general well-being. CONCLUSION: There is scope for improved awareness of vitamin D and the risks for deficiency in the ambulance setting. It appears service staff are at risk of vitamin D deficiency irrespective of their role: access to sunlight and use of vitamin D supplements are variable. The physical and mental impacts of deficiency can be significant, requiring absence from work. The development of appropriate vitamin D and well-being resources appears to be warranted.

A survey-based evaluation of ambulance staff awareness of vitamin D and risk of deficiency in a UK ambulance service.

BACKGROUND: Healthcare professions, shift-working and indoor-working are risk factors for vitamin D deficiency. The aim of this survey was to investigate ambulance staff awareness of vitamin D, and the risks associated with deficiency, to inform the need for appropriate well-being resources. METHODS: A purpose-designed, 20-question survey was developed, based on a validated vitamin D questionnaire, to explore staff vitamin D knowledge and self-health in one UK ambulance service. Disseminated during June/July 2020, survey completion was voluntary, and responses obtained were analysed using descriptive and thematic approaches. RESULTS: A total of 384 survey responses were received; 41% (n = 156) of respondents were male. Over half worked within emergency operational service delivery (57%; n = 219). Respondents were predominantly 'White British' (92%; n = 352). According to the Fitzpatrick Scale, most described themselves as having a 'Medium, between white to moderate brown: sometimes mild burns, gradual tan' complexion (47%; n = 182). The majority felt they got sufficient sunlight exposure when at home (66%; n = 253), but not at work (58%; n = 222). Almost one fifth (17%; n = 66) had received a diagnosis of vitamin D deficiency. Forty percent took vitamin D supplements: 12% (n = 45) as advised by a medical professional; 28% (n = 107) self-directed to prevent deficiency. The ability of respondents to recognise known factors that affect vitamin D production in the skin, good vitamin D food sources and individuals at risk of vitamin D deficiency were variable. Respondents commented on their lack of vitamin D awareness, vitamin supplementation, COVID-19, work arrangements and access to sunlight. CONCLUSIONS: Ambulance staff are at risk of vitamin D deficiency irrespective of their role: vitamin D awareness, access to sunlight and use of vitamin D supplements are variable. For affected individuals, the impact of vitamin D deficiency can be significant, requiring absence from work. The development of appropriate vitamin D and well-being resources appears to be warranted.

'Menopause affects us all . . .': menopause transition experiences of female ambulance staff from a UK ambulance service.

BACKGROUND: There is limited research regarding the menopause transition in the emergency services; however, all women will experience this life phase, which can have a significant impact on personal well-being, workplace attendance and performance. The aim of this survey was to explore personal and work impacts of the menopause for all female staff in the ambulance setting. METHODS: A purpose-designed, 20-question survey, based on the Menopause Rating Scale and British Menopause Survey, was developed to understand menopausal symptoms and their impact on female staff in one UK ambulance service. Disseminated during 1-31 July 2019, it resulted in a convenience sample of 522 responses, which were analysed using descriptive statistics and thematic approaches. RESULTS: Typically, respondents were either pre-menopausal or peri-menopausal, with approximately a third being menopausal or post-menopausal. Over half worked in emergency operational delivery, and typically worked shifts or unsocial hours. For those who had experienced menopause symptoms, the most commonly reported were tiredness or low energy levels, difficulty sleeping (including insomnia) and mood changes (including anxiety or depression). Symptoms impacted respondents' well-being, work and home life. Most had not expected the symptoms they experienced. The majority of respondents did not feel supported at work, with lack of menopausal symptom awareness and personal impact, working times and patterns, and sense of embarrassment of most concern. Other issues included lack of managerial and peer support, inadequate working environment and uniform, lack of dignity and choice, and no dedicated menopause policy. CONCLUSIONS: It is understood that this is the first survey to explore female ambulance staff menopause experiences. The impact of menopausal symptoms can be significant. Menopause awareness in this ambulance service is lacking and there is clear scope for initiatives for improved staff support and well-being. Further research is warranted to explore how best to support ambulance staff with the menopause transition.

How do people with dementia use the ambulance service? A retrospective study in England: the HOMEWARD project.

OBJECTIVES: An increasing number of older people are calling ambulances and presenting to accident and emergency departments. The presence of comorbidities and dementia can make managing these patients more challenging and hospital admission more likely, resulting in poorer outcomes for patients. However, we do not know how many of these patients are conveyed to hospital by ambulance. This study aims to determine: how often ambulances are called to older people; how often comorbidities including dementia are recorded; the reason for the call; provisional diagnosis; the amount of time ambulance clinicians spend on scene; the frequency with which these patients are transported to hospital. METHODS: We conducted a retrospective cross-sectional study of ambulance patient care records (PCRs) from calls to patients aged 65 years and over. Data were collected from two ambulance services in England during 24 or 48 hours periods in January 2017 and July 2017. The records were examined by two researchers using a standard template and the data were extracted from 3037 PCRs using a coding structure. RESULTS: Results were reported as percentages and means with 95% CIs. Dementia was recorded in 421 (13.9%) of PCRs. Patients with dementia were significantly less likely to be conveyed to hospital following an emergency call than those without dementia. The call cycle times were similar for patients regardless of whether or not they had dementia. Calls to people with dementia were more likely to be due to injury following a fall. In the overall sample, one or more comorbidities were reported on the PCR in over 80% of cases. CONCLUSION: Rates of hospital conveyance for older people may be related to comorbidities, frailty and complex needs, rather than dementia. Further research is needed to understand the way in which ambulance clinicians make conveyance decisions at scene.
