Background: Heat stroke is an emergent condition characterized by hyperthermia (>40 °C/>104 °F) and nervous system dysregulation. There are two primary etiologies: exertional which occurs during physical activity and non-exertional which occurs during extreme heat events without physical exertion. Left untreated, both may lead to significant morbidity, are considered a special circumstance for cardiac arrest, and cause of mortality. Methods: We searched Medline, Embase, CINAHL and SPORTDiscus. We used Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods and risk of bias assessments to determine the certainty and quality of evidence. We included randomized controlled trials, non-randomized trials, cohort studies and case series of five or more patients that evaluated adults and children with non-exertional or exertional heat stroke or exertional hyperthermia, and any cooling technique applicable to first aid and prehospital settings. Outcomes included: cooling rate, mortality, neurological dysfunction, adverse effects and hospital length of stay. Results: We included 63 studies, of which 37 were controlled studies, two were cohort studies and 24 were case series of heat stroke patients. Water immersion of adults with exertional hyperthermia [cold water (14¿17 °C/57.2¿62.6 °F), colder water (8¿12 °C/48.2¿53.6 °F) and ice water (1¿5 °C/33.8¿41 °F)] resulted in faster cooling rates when compared to passive cooling. No single water temperature range was found to be associated with a quicker core temperature reduction than another (cold, colder or ice). Conclusion: Water immersion techniques (using 1¿17 °C water) more effectively lowered core body temperatures when compared with passive cooling, in hyperthermic adults. The available evidence suggests water immersion can rapidly reduce core body temperature in settings where it is feasible.

This is the summary publication of the International Liaison Committee on Resuscitation's 2020 International Consensus on First Aid Science With Treatment Recommendations. It addresses the most recent published evidence reviewed by the First Aid Task Force science experts. This summary addresses the topics of first aid methods of glucose administration for hypoglycemia; techniques for cooling of exertional hyperthermia and heatstroke; recognition of acute stroke; the use of supplementary oxygen in acute stroke; early or first aid use of aspirin for chest pain; control of life-threatening bleeding through the use of tourniquets, hemostatic dressings, direct pressure, or pressure devices; the use of a compression wrap for closed extremity joint injuries; and temporary storage of an avulsed tooth. Additional summaries of scoping reviews are presented for the use of a recovery position, recognition of a concussion, and 6 other first aid topics. The First Aid Task Force has assessed, discussed, and debated the certainty of evidence on the basis of Grading of Recommendations, Assessment, Development, and Evaluation criteria and present their consensus treatment recommendations with evidence-to-decision highlights and identified priority knowledge gaps for future research.

Background/Aim: It is crucial to store an avulsed tooth appropriately to preserve the viability of the periodontal ligament cells prior to replantation. The aim of this systematic review was to identify the best available evidence for the effectiveness of any technique available to laypeople for storing an avulsed tooth compared with storage in milk or saliva. Methods: The following databases were searched (September 2019): Cochrane Library, MEDLINE, and Embase. Two reviewers independently considered trial eligibility, then extracted and analyzed data, and assessed the risk of bias. The certainty of the body of evidence was appraised according to the GRADE methodology. Results: Out of 4118 references, 33 studies were included and reported 23 comparisons of which 10 were synthesized in a meta-analysis. The limited evidence available favors storing an avulsed tooth in Hank's balanced salt solution (pooled SMD 2.47, 95% CI [1.59;3.34], P¿<.00001), propolis solution (pooled SMD 1.73, 95% CI [1.12;2.33], P¿<.00001), oral rehydration salts (pooled SMD 4.16, 95% CI [2.10;6.23], P¿<.0001), rice water, and cling film compared with storage in milk. The cell viability rate was significantly lower in teeth stored in saline solutions (pooled SMD -4.35, 95% CI [-7.55;-1.14], P¿=.008), tap water, buttermilk, castor oil, GC Tooth Mousse, and turmeric extract than those stored in milk. There is insufficient evidence to recommend for or against temporary storage of an avulsed tooth in saliva compared with alternative solutions. The certainty of evidence was considered low to very low due to limitations in study design, indirect study populations and outcome measures, and imprecision. Conclusion: Although milk was shown to extend the periodontal ligament cell viability before replantation compared with saline or tap water, the following media have also demonstrated efficacy at preserving the cell viability: Hank's balanced salt solution, propolis, oral rehydration salts, rice water, and cling film.

The International Liaison Committee on Resuscitation has initiated a continuous review of new, peer-reviewed, published cardiopulmonary resuscitation science. This is the third annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations. It addresses the most recent published resuscitation evidence reviewed by International Liaison Committee on Resuscitation Task Force science experts. This summary addresses the role of cardiac arrest centers and dispatcher-assisted cardiopulmonary resuscitation, the role of extracorporeal cardiopulmonary resuscitation in adults and children, vasopressors in adults, advanced airway interventions in adults and children, targeted temperature management in children after cardiac arrest, initial oxygen concentration during resuscitation of newborns, and interventions for presyncope by first aid providers. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the certainty of the evidence on the basis of the Grading of Recommendations, Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations. Insights into the deliberations of the task forces are provided in the Justification and Evidence to Decision Framework Highlights sections. The task forces also listed priority knowledge gaps for further research.

Background: approximately 25% of older people who fall and receive paramedic care are not subsequently transported to an emergency department (ED). These people are at high risk of future falls, unplanned healthcare use and poor health outcomes. Objective: to evaluate the impact of a fall-risk assessment and tailored fall prevention interventions among older community-dwellers not transported to ED following a fall on subsequent falls and health service use. Design, setting, participants: Randomised controlled trial involving 221 non-transported older fallers from Sydney, Australia. Intervention: the intervention targeted identified risk factors and used existing services to implement physiotherapy, occupational therapy, geriatric assessment, optometry and medication management interventions as appropriate. The control group received individualised written fall prevention advice. Measurements: primary outcome measures were rates of falls and injurious falls. Secondary outcome measures were ambulance re-attendance, ED presentation, hospitalisation and quality of life over 12 months. Analysis was by intentionto- treat and per-protocol according to self-reported adherence using negative binominal regression and multivariate analysis. Results: ITT analysis showed no significant difference between groups in subsequent falls, injurious falls and health service use. The per-protocol analyses revealed that the intervention participants who adhered to the recommended interventions had significantly lower rates of falls compared to non-adherers (IRR: 0.53 (95% CI: 0.32-0.87)). Conclusion: a multidisciplinary intervention did not prevent falls in older people who received paramedic care but were not transported to ED. However the intervention was effective in those who adhered to the recommendations. Trial registration: the trial is registered at the Australian New Zealand Clinical Trials Registry: ACTRN 12611000503921, 13/05/2011.

Background: Older fallers constitute a large proportion of ambulance work, and as many as 25% are not transported to hospital following paramedic assessment. The objective of this study was to explore the decision making process used by paramedics when caring for older fallers. Methods: A qualitative study was conducted using constructivist grounded theory methodology. Purposive sampling was used to recruit paramedics to participate in semi-structured interviews and focus groups. Data analysis commenced with line-by-line coding, developing into formation of theoretical categories. Theoretical sampling was then used to clarify emerging theoretical concepts, with data collection and analysis continuing until theoretical saturation was achieved. Results: A total of 33 paramedics participated in 13 interviews and 4 focus groups. When caring for older fallers, paramedic decision making is profoundly affected by ¿role perception¿, in which the individual paramedic¿s perception of what the role of a paramedic is determines the nature of the decision making process. Transport decisions are heavily influenced by a sense of ¿personal protection¿, or their confidence in the ambulance service supporting their decisions. ¿Education and training¿ impacts on decision making capacity, and the nature of that training subliminally contributes to role perception. Role perception influences the sense of legitimacy a paramedic attaches to cases involving older fallers, impacting on patient assessment routines and the quality of subsequent decisions. Conclusions: Paramedic decision making processes when caring for older people who have fallen appear to be strongly influenced by their perception of what their role should be, and the perceived legitimacy of incidents involving older fallers as constituting ¿real¿ paramedic work.

Introduction Ambulance use in rural and remote parts of Australia has been reported anecdotally to be lower than urban areas. Experiences of paramedics in rural locations gave rise to questions of whether this phenomenon was occurring and to what degree. Methods Data from emergency department (ED) records was obtained from the Hunter New England Area Health Service from 1 July 2008 to 30 June 2009. In total, 354,909 records were obtained. These records were de-identified and analysed to determine the method of arrival to ED, specifically in high acuity patients. Results People from inner regional areas are 41.5% less likely overall and 27.7% less likely in serious health emergencies to attend EDs by ambulance compared to people in major cities. People from outer regional and remote areas are 55.1% less likely overall and 27.9% less likely in serious health emergencies to attend EDs by ambulance compared to people living in major cities. Logistic regression modelling indicated rurality was a significant factor in ambulance use in adults in areas outside major cities and in children in inner regional areas. Age was a significant predictor of ambulance demand with older people using ambulances more. Discussion This study indicates disparity between rates of ambulance use in urban and non-urban areas. The concept of unmet need should be considered as a more complex phenomenon than simply a utilisation gap and exploration of unmet need is warranted. Conclusion A clearer understanding of how rurality affects ambulance use has a number of implications for ambulance services.

Objective. To determine whether analgesic administration in the out-of-hospital setting is influenced by the gender of the patient or the gender of the paramedic. Methods. This retrospective cohort study of patient care records included adult patients (age > 15 years) with moderate to severe pain (verbal numerical rating score 4-10) treated by paramedics between January 1, 2008 and December 31, 2009. Data extracted included patient pain severity score, analgesia provided by paramedics, and gender of the treating paramedic. Data was analyzed by descriptive statistics, ¿2 test, and logistic regression. The primary outcome measures were the effect of patient and paramedic gender on analgesic administration. Results. The study population comprised 42,051 patients, median age of 57 years (38-75); 50.4% were female and 51% were administered an analgesic agent. For the outcome of receiving any analgesia, neither patient gender nor paramedic gender was predictive (p = NS). In a multivariate model for the outcome of receiving any analgesia, patient gender, paramedic gender, and the interaction between patient and paramedic gender were all nonsignificant (p = NS). For the outcome of receiving opioid analgesia (i.e., morphine or fentanyl), male patients were at greater odds of receiving an opioid (OR 1.52, 95% CI 1.29-1.79, p < 0.0001). Paramedic gender was not predictive of whether an opioid was given (p = NS). Conclusions. The gender of the paramedic did not appear to influence the odds of analgesic administration. Female patients were less likely to receive opioids. Paramedic gender does not explain this finding. © 2014 National Association of EMS Physicians.

Epidemiology of older fallers attended by paramedics: A study of clinical and operational outcomes.
Falls is the most common incident category to which an emergency ambulance is dispatched in New South Wales (NSW), with approximately 60% of these involving patients aged 65 years or more. This thesis explores the epidemiology of older fallers attended by paramedics, employing a mix of quantitative and qualitative research methods with the aim of providing new information in an area of paramedic practice about which little is known. A retrospective, population-level study (n=42,331), prospective cohort study (n=1,610), and retrospective linked data analysis (n=34,313) form the basis of the epidemiological analyses, reporting operational and clinical outcomes arising from an ambulance response and paramedic intervention. A qualitative investigation, using grounded theory methodology, presents a theoretical model exploring paramedic decision making when providing care to older people who have fallen. Significant findings include:1. Older fallers constitute 5.1% of the annual emergency ambulance workload in NSW; 28% are not transported to hospital.2. 1 in 10 older fallers who receive an ambulance response experience a &amp;lsquo;long lie&amp;rsquo; (&amp;gt;1 hour on the ground).3. Prediction of non-transport at time of dispatch is not feasible for cases involving older fallers, making risk management through dispatch of specialised resources unfeasible.4. Rates of analgesia administration among fallers with suspected hip fracture (67%) has increased compared to earlier research, but almost one third still receive no prehospital pain relief.5. Non-transported older fallers are at twice the risk of death at 28 days compared to those transported to ED and discharged without admission. Ambulance re-attendance within one month is common.6. Paramedics do not perceive cases involving older fallers to be &amp;lsquo;real paramedic work&amp;rsquo;. This arises from confusion around role perception, and impacts negatively on the clinical decision making relating to the treatment of older fallers.The findings of this thesis constitute a comprehensive analysis of an area of paramedicine about which little was previously known in an Australasian context. The results will inform clinical and operational strategy being developed by ambulance services and will make a meaningful contribution to optimising prehospital service delivery to, and improving outcomes of, older people who have fallen.
