      Background Diabetes, which affects over 1 in 5 nursing or care home residents, may lead to diabetes-related emergencies with ambulance call-outs and hospitalisation. Our aim was to investigate the epidemiology of diabetes-related emergencies in care home residents which involved an ambulance attendance. Methods We used a cross-sectional design to investigate emergency ambulance attendances to people in nursing and residential care homes presenting with diabetes-related emergencies across the East Midlands between January 2012 and December 2017. We used clinical and dispatch data from East Midlands Ambulance Service NHS Trust (EMAS) and care home data from the Care Quality Commission, including call category, timing, location, place of residence, clinical or physiological status, treatments, outcome (conveyance) and costs in the analysis. Results Overall 219722 (6.7% of 3.3 million) attendances were to care home residents of which 12080 were for diabetes-related emergencies. Of 3152 care home patients categorised as having a ‘diabetic problem’ 1,957 (62.1%) were conveyed to hospital. This was not significantly different to the rate for other patients, taking into account other factors, despite access to trained staff in care homes. Statistically significant factors associated with conveyance included reduced consciousness level (OR 0.91, 95% CI 0.87–0.95), elevated heart (1.01, 1.01–1.02) or respiratory rate (1.08, 1.06–1.10), no treatment for hypoglycaemia (0.54, 0.34–0.86) or additional co-morbid medical (but not psychiatric) problems. Cost to EMAS was significantly lower when a patient was conveyed, by some £18 (95% CI £11.94–£24.12), but this would not outweigh downstream NHS costs arising from hospital care. For the simulation in which all trusts mean NHS Reference Costs were used, conveyance was no longer significant in the cost model. Conclusion Conveyance to hospital was common for care home patients with diabetes-related emergencies and more likely when conscious level was impaired, certain physiological measures abnormal or treatment for hypoglycaemia was not given. https://emj.bmj.com/content/36/10/e8.3 This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial.

    • Ambulances attending diabetes-related emergencies in care homes – cross sectional database study

      Siriwardena, Aloysius; Law, Graham; Smith, M.D.; Iqbal, Mohammad; Phung, Viet-Hai; Spaight, Anne; Brewster, Amanda; Mountain, P.; Spurr, K.; Ray, M.; et al. (2019-04-26)
      Background Diabetes, affecting 1 in 5 care home residents, may lead to ambulance call-outs and hospitalisation. We aimed to investigate the epidemiology of diabetes-related emergencies involving ambulance attendances to care home residents. Method Cross-sectional design investigating ambulance attendance to people presenting with diabetes-related emergencies in the East Midlands, UK, between 2012 and 2017. We analysed dispatch and ambulance clinical data with care home data, including call category, timing, location, care home type, clinical or physiological measures, treatments, conveyance (transport to hospital) and costs. Results Overall 2 19 722 (6.7% of 3.3 million) ambulances attended care homes over 6 years, with 12 080 (5.5%) to diabetes-related emergencies. Of 3152 care home patients categorised as having a ‘diabetic problem’, 1957 (62.1%) were conveyed to hospital, similar to that for community residents taking into account other factors. Factors associated with conveyance included reduced consciousness (OR 0.91, 95% CI 0.87–0.95), elevated heart (1.01, 1.01–1.02) or respiratory rate (1.08, 1.06–1.10), no treatment for hypoglycaemia (0.54, 0.34–0.86) or additional medical (but not psychiatric) problems. Ambulance costs were significantly lower when a patient was conveyed, by some £18 (95% CI £11.94–£24.12), but this would be outweighed by downstream hospital care costs. For a simulation in which all trusts’ mean NHS Reference Costs were used, conveyance was no longer significant in the cost model. Conclusion Conveyance following diabetes-related emergencies was as common for care home as for other community residents despite access to trained staff, and more likely with impaired consciousness, abnormal physiological measures or lack of treatment for hypoglycaemia.

    • Barriers and facilitators for people in BME groups accessing pre-hospital care and causes and consequences of any differences in delivery: systematic review and narrative synthesis

      Windle, Karen; Siriwardena, Aloysius; Barot, Mukesh; Essam, Nadya; Johnson, Mark; Kai, Joe; Ortega, Marishona (2015-05)
      Introduction Research addressing inequalities has focused predominantly on primary and community care; few initiatives relate to the pre-hospital environment. We aimed to identify in the literature barriers or facilitators experienced by patients from BME communities in accessing pre-hospital care and to explore the causes and consequences of any differences in delivery. Methods We conducted a systematic literature review and narrative synthesis. Electronic and journal hand searches from 2003 through 2013 identi fied relevant evaluative studies (systematic reviews, randomised controlled trials, quasi-experimental, case and observational studies). A researcher extracted data to determine characteristics, results and quality, each checked by a second reviewer. The main outcome measures were delays in patient calls, mortality rates and 30-days survival post discharge. Results Eighteen studies met criteria for the review: two concerned services in England and Wales and 15 were United States based. Reported barriers to accessing care were generic (and wellknown) given the heterogeneity of BME groups: difficulties in communication where English was the patient ’s second language; new migrants ’ lack of knowledge of the health care system leading to inappropriate emergency calls; and cultural assumptions among clinical staff resulting in inappropriate diagnoses and treatment. There were limited reported facilitators to improvement, such as the need for translation services and staff education, but the latter were poorly described or developed. Where outcomes were discussed, there was evidence for race-related disparity in mortality and survival rates. This could re flect differences in condition severity, delays between onset and initiation of calls, or the scope of response and assistance. Conclusion The paucity of literature and difficulties of transferring findings from US to UK context identified an important research gap. Further studies should be undertaken to investigate UK differences in prehospital care and outcomes for BME groups, followed by qualitative approaches to understand barriers and enablers to equitable access. https://emj.bmj.com/content/emermed/32/5/e1.3.full.pdf This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial.

    • Can older people who fall be identified in the ambulance call centre to enable alternative responses or care pathways?

      Snooks, Helen; Cheung, Wai Yee; Gwini, Stella; Humphreys, Ioan; Sanchez, Antonio; Siriwardena, Aloysius (2011-03-01)
      Background Older people who fall make up a substantial proportion of the 999 workload. They are a particularly vulnerable group who may benefit from referral to specialised community based falls services. This requires early identification, ideally from dispatch codes assigned in the ambulance call centre. Objective To assess the feasibility of using information given during 999 calls to identify older people who fall and who may benefit from an alternative response. Methods We examined all records of patients aged 65 years and over during 2008 in the Nottinghamshire area and identified those recorded as having fallen by attending crews. Dispatch codes were recorded for all cases and the utility of the dispatch code ‘Fall without priority symptoms’ (AMPDS 17) for identifying older people who had fallen was assessed. Results From 56 584 emergency (999) calls recorded, including 8119 for patients aged 65 years and over, 3246 (40%) cases were recorded as a fall. Of these, 2186 (67%) had been allocated AMPDS code 17 at dispatch (true positives), and 413 (13%) had not (false negatives), with 647 unknowns. Of 4871 cases not categorised as a fall by attending crews, 175 (4%) had been allocated an AMPDS code 17 (false positives), and 3315 (68%) had been given other codes (true negatives), with 1381 unknowns. The dispatch code AMPDS 17 had a sensitivity of 84% and a specificity of 95% for identifying falls compared with categorisation by crews. Limitations Definition of a fall is not always clear and there may be variations in usage of the category by crews. There was a high level of missing data in this study. Conclusion A large majority of older people who fall and for whom a 999 call is made can be identified in the ambulance call centre using dispatch codes. This provides a means for rapid and effective targeting of alternative responses to these patients, thereby potentially improving processes and outcomes of care. https://emj.bmj.com/content/28/3/e1.21.

    • A case study framework for design and evaluation of a national project to improve prehospital care of myocardial infarction and stroke

      Essam, Nadya; Davy, Zowie; Shaw, Deborah; Spaight, Anne; Siriwardena, Aloysius (2011-11)
      Background Cardiovascular disease (CVD) affects 1.8% of the population annually, 0.9% with stroke and 0.8% with coronary heart disease. People suffering from CVD often present acutely to ambulance services with symptoms of acute myocardial infarction or stroke. Early and effective treatment prevents death, improves long term health and reduces future disability. Objective Our aim is to develop a rational approach for informing the design and evaluation of a national project for improving prehospital care of myocardial infarction and stroke: the Ambulance Services Cardiovascular Quality Initiative (ASCQI), the first national improvement project for prehospital care. Methods We will use a case study methodology initially utilising an evaluation logic model to define inputs (in terms of resources for planning, implementation and evaluation), outputs (in terms of intended changes in healthcare processes) and longer-term outcomes (in terms of health and wider benefits or harms), whether intended or incidental and in the short, medium or long term. Results We will present an evaluation logic model for the project. This will be expanded to show the analytical techniques which we will use to explain how and why the project achieves its outcomes. This includes times series analyses, pattern matching, cross case syntheses and explanation building to inform an explanatory logic model. We will discuss how this model will be useful in determining the data that will need to be collected during the course of the project to inform the detailed explanation of how and why the project delivered its outcomes. Conclusion The case study approach will enable us to evaluate the impact of this collaborative project in constituent ambulance services as well as the initiative as a whole. It will enable us to show whether and to what extent the project has had an impact, but also how and why this has happened. https://emj.bmj.com/content/emermed/28/11/e2.7.full.pdf This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial.

      Paramedic tracheal intubation has been practised in the UK for more than 20 years and is currently a core skill for paramedics. Growing evidence suggests that tracheal intubation is not the optimal method of airway management by paramedics and may be detrimental to patient outcomes. There is also evidence that the current initial training of 25 intubations performed in-hospital is inadequate, and that the lack of ongoing intubation practice may compound this further. Supraglottic airway devices (eg, laryngeal mask airway), which were not available when extended training and paramedic intubation was first introduced, are now in use in many ambulance services and are a suitable alternative prehospital airway device for paramedics. https://emj.bmj.com/content/27/3/226.long.

    • Investigation of patient and practitioner views on improving pain management in the prehospital settings

      Iqbal, Mohammad; Spaight, Anne; Siriwardena, Aloysius; Shaw, Deborah (2011-03)
      Background Pre-hospital pain management is increasingly important with most patients (80%) presenting to UK ambulance services in pain. Around 20% of patients want more pain relief and 5% feel that ambulance crews do not adequately treat pain. A recent study in the East Midlands showed that 85.1% of AMI patients and 75% of fracture patients had a pain score but fewer than a quarter of patients assessed for and experiencing pain with either condition received opiates. Improving the pathway of prehospital pain management is therefore important and a key indicator of the quality of service. Objective We gathered data on perspectives of pain management from patients, ambulance and accident and emergency (A&E) care staff in Lincolnshire. Method Qualitative data were gathered through focus group (5) and interviews (28). Participants were purposively sampled from patients recently transported to hospital with pain, ambulance staff and A&E clinicians. Interviews were audiotaped and transcribed. Data were manipulated using MAXQDA and thematic analysis used iteratively to develop themes. Results Themes emerging from the data included: (a) expectations and beliefs (b) assessment methods (c) drug treatment (d) non-drug treatment and (e) improvement strategies for pain. Patients and staff expected pain to be relieved in the ambulance; instances of refusal or inadequate analgesia were not uncommon. Pain was commonly assessed using a verbal pain score; clinical observation was also used which sometimes led to discordance between subjective experience and clinical assessment. Morphine, Entonox and oxygen were commonly used to treat pain. Reassurance, positioning and immobilisation were alternatives to drugs. Suggestions to improve prehospital pain management included addressing barriers, modifying the available drugs and developing a prehospital pain management protocol supported by training for staff. Conclusion The findings will be used to develop an educational intervention for better pain assessment and management in the prehospital setting. https://emj.bmj.com/content/emermed/28/3/e1.12.full.pdf This is an Open Access article distributed in accordance with the Creative Commons Attribution Non Commercial (CC BY-NC 4.0) license, which permits others to distribute, remix, adapt, build upon this work non-commercially, and license their derivative works on different terms, provided the original work is properly cited and the use is non-commercial.

    • Prehospital intravenous cannulation: reducing the risks and rate from inappropriate venous access by paramedics

      Iqbal, Mohammad; Banerjee, Smita C.; Spaight, Anne; Stephenson, John; Siriwardena, Aloysius (2009-10)
      Background Prehospital intravenous (IV) cannulation by paramedics is a key intervention which enables administration of fluids and drugs in the prehospital setting. Inappropriate use and poor technique of IV cannulation carry potential risks for patients such as pain and infection. Cannulation rates vary widely between paramedics and ambulance stations and rates have increased over the past decade. A baseline audit carried out in Lincolnshire division of East Midlands Ambulance Service (EMAS) in 2006 found that paramedics cannulated 14.2% of transported patients and cannulation rates varied considerably between ambulance stations, with a mean rate of 13.4% (range 5.8% to 19%). An estimated 15.6% of these cannulations could have been avoided. Objective This evaluation was aimed at investigating the effect of a complex educational intervention to reduce the rate of cannulation and improve cannulation technique in EMAS NHS Trust which provides emergency and unscheduled care in six counties of the UK. Method A non-randomised control group (before and after) design was used to evaluate the effect of the educational intervention. Two geographical areas of EMAS were involved in the study; an intervention area (Nottinghamshire) was compared with a control area (Lincolnshire). The educational intervention was based on current guidance (JRCALC) and delivered to paramedic team leaders who cascaded it to their teams. Comparisons between the areas were made by analysing cannulation rates 2 months before and after intervention. Paramedics, 50 in each group, were assessed on technique, appropriateness and attitude towards cannulation. Results Preliminary results showed that there was a reduction in cannulation rates in the intervention area from 9.1% to 6.5% compared with an increase in the control area from 13.8 to 19.1%. Paramedics in the intervention group were significantly more likely to use correct consent and hand washing techniques following the intervention. https://emj.bmj.com/content/26/10/1.2.

    • Supporting research and development in ambulance services: research for better health care in prehospital settings

      Siriwardena, Aloysius; Donohoe, Rachel; Stephenson, John; Phillips, Paul (2010-04-12)
      Background This paper discusses recent developments in research support for ambulance trusts in England and Wales and how this could be designed to lead to better implementation, collaboration in and initiation of high-quality research to support a truly evidence-based service. Method The National Ambulance Research Steering Group was set up in 2007 to establish the strategic direction for involvement of regional ambulance services in developing relevant and well-designed research for improving the quality of services to patients. Results Ambulance services have been working together and with academic partners to implement research and to participate, collaborate and lead the design of research that is relevant for patients and ambulance services. Conclusion New structures to support the strategic development of ambulance and prehospital research will help address gaps in the evidence for health interventions and service delivery in prehospital and ambulance care and ensure that ambulance services can increase their capacity and capability for high-quality research. https://emj.bmj.com/content/27/4/324.

    • Traumatic brain injuries: continuing dilemmas in the pre-hospital care arena

      Griffin, Dylan (2013-02)
      Abstract published with permission. This article examines the clinical assessment, diagnosis and management of an agitated traumatic brain-injured patient in the pre-hospital setting by a UK Helicopter Emergency Medical (HEMS) Team. Using a case study from clinical practice, the signs and symptoms, aetiology and clinical management options are discussed and compared against current best evidence, with the specific aims of improving mortality and morbity in critically-ill traumatic brain-injured patients.
