Battlefield acupuncture added no benefit as an adjunct analgesic in emergency department for abdominal, low back or limb trauma pain.

OBJECTIVES: To ascertain whether ear acupuncture (modified Battlefield technique) as an adjunct (Adj-BFA) to standard analgesia care (SAC) significantly reduces pain scores compared with sham acupuncture (Adj-Sham) or SAC alone, when delivered by medical and nursing practitioners in an ED. METHODS: A randomised controlled trial using a convenience sample of 90 patients attending an ED with acute abdominal, limb trauma or low back pain were allocated to three treatment arms: Adj-BFA, Adj-Sham and SAC. The primary outcome of change in pain scores out-of-10 (NPRS-10) from triage were assessed immediately after intervention and at 1 and 2 h post-intervention. Secondary outcomes were the percentage of patients reporting 'adequate analgesia' or ≥30% reduction in pain score, analgesic medication use (in morphine equivalent dose [milligrammes]), analgesics and needle costs (Australian dollars), adverse effects and patient satisfaction (Likert scale). RESULTS: There was no significant difference in pain scores (P = 0.582) or secondary outcomes measures between Adj-BFA, Adj-Sham and SAC. CONCLUSION: The present study on 90 patients did not show a significant difference in analgesia outcomes in the first 2 h using Adj-BFA for acute pain in the ED, and there were no significant differences for secondary outcomes between treatment arms. Given the mixed results of recent BFA trials, further research using the original BFA technique on different painful conditions, as either stand-alone or as-adjunct to non-opioid analgesia are needed before BFA can be recommended as a technique for acute pain management in the ED.

Why do paramedics choose to bring patients to a private emergency department?

OBJECTIVE: While prior experience, favourable location and anticipation of high quality care are known to influence patient choice to attend a private ED, it is likely that decision-making is also influenced by other persons. In particular, patients arriving by ambulance are under the care of paramedics, whose values towards healthcare and rationale for choosing one ED over another have not been studied. This study aimed to describe reasons why paramedics choose to bring patients to a private ED. METHODS: Exploratory, qualitative study using semi-structured, face-to-face interviews with paramedics bringing patients to a private ED from the community. Two primary questions reinforced by structured prompts were asked: 'Why did you choose to come to this emergency department?' and 'What are your general expectations of this emergency department visit?' Interviews were audio recorded, transcribed verbatim and analysed thematically. RESULTS: Fifty paramedics were interviewed with 48 interviews able to be transcribed and used in analysis. Four factors were identified to increase the likelihood of a private ED destination: specific direction, institutional allegiance, hospital logistics and systems and receiving hospital service ethos. CONCLUSIONS: Paramedics take into consideration when possible patient's wishes and are more likely to bring a patient to a private ED if they have specific direction from the patient or the patient's family or GP. The likelihood of presenting to a private ED is increased if the patient has an allegiance with the facility and the paramedics perceive favourably the hospital logistics and systems as well as service ethos.

Patient attitudes towards analgesia and their openness to non-pharmacological methods such as acupuncture in the emergency department.

OBJECTIVE: To investigate patient attitudes to analgesia, opioids and non-pharmacological analgesia, including acupuncture, in the ED. METHODS: ED patients with pain were surveyed regarding: pain scores, satisfaction, addiction concern, non-pharmacological methods of pain relief and acupuncture. Data were analysed using logistic regression. RESULTS: Of 196 adult patients, 52.8% were 'very satisfied' with analgesia. Most patients (84.7%) would accept non-pharmacological methods including acupuncture (68.9%) and 78.6% were not concerned about addiction. Satisfaction was associated with male gender, and 'adequate analgesia' but not with opioids. CONCLUSION: Most patients were generally satisfied with ED analgesia and were open to non-pharmacologic analgesia including acupuncture.

Does Ear Acupuncture Have a Role for Pain Relief in the Emergency Setting? A Systematic Review and Meta-Analysis.

Objective: Ear acupuncture might be the form of acupuncture best suited to improving acute pain management in the emergency department (ED). The primary aim of this review was to assess the analgesic efficacy of ear acupuncture in the ED. Secondary outcomes included measures of patient satisfaction, adverse effects, cost, administration techniques, and reduction of medication usage. Methods: Seven databases and Google Scholar were searched up to April 27, 2017, using MeSH descriptors for three overarching themes (ear acupuncture, pain management, and emergency medicine). Meta-analyses were performed in 3 comparator groups: (1) ear acupuncture versus sham; (2) ear acupuncture-as-adjunct to standard care; and (3) ear acupuncture (both as sole therapy and adjuvant) versus control to calculate the standardized mean difference (SMD) and weighted mean difference (WMD) for pain scores out of 10. Results: Six randomized controlled trials and 2 observational studies, totaling 458 patients, were retrieved after exclusions. The meta-analysis used data from 4 randomized studies representing 286 patients. The above 3 comparator groups resulted in SMDs of 1.69, 1.68, and 1.66, and WMDs of 2.47, 2.84, and 2.61 respectively, all favoring acupuncture. Battlefield (ear) acupuncture was the most commonly used technique. There were no significant adverse effects and patient satisfaction improved. Results regarding if acupuncture reduced medication use were equivocal. Significant study bias and heterogeneity were found. Conclusions: While study numbers are limited, ear acupuncture, either as stand-alone or as-an-adjunct technique, significantly reduced pain scores and has potential benefits for use in the ED. Further studies will define acupuncture's role and if it reduces use of analgesic medications.

Review article: Does acupuncture have a role in providing analgesia in the emergency setting? A systematic review and meta-analysis.

Acupuncture might offer a novel approach to improve ED pain management. Our primary aim was to assess the efficacy of acupuncture in the emergency setting while secondary objectives were to explore its suitability through its side-effect profile, patient satisfaction, cost, administration time and points used. Seven databases and Google Scholar were searched up to 31 July 2016 using MeSH descriptors for three overarching themes concerning acupuncture, pain management and emergency medicine. Meta-analysis was performed on randomised trials for three comparator groups: acupuncture versus sham, acupuncture versus standard analgesia care and acupuncture-as-an-adjunct to standard care, to calculate the standardised mean difference and weighted mean difference for pain scores out of 10. Data for secondary outcomes was extracted from both randomised and observational studies. Nineteen randomised controlled trials and 11 uncontrolled observational studies totaling 3169 patients were retrieved after exclusions. Meta-analyses were performed on data from 14 randomised controlled trials representing 1210 patients. The three resulting comparator groups (as above) resulted in standardised mean differences of 1.08, 0.02 and 1.68, and weighted mean differences of 1.60, -0.04 and 2.84, respectively (all positive figures favour acupuncture). Where measured, acupuncture appears to be associated with improved patient satisfaction, lower cost and a low adverse effects profile. The data available were inadequate to ascertain the effect of acupuncture on analgesia use. Significant study bias was found, especially with respect to practitioner and patient blinding. We conclude that for some acute pain conditions in the ED, acupuncture was clinically effective compared to sham and non-inferior to conventional therapy. As an adjunct, limited data was found indicating superiority to standard analgesia care. Further studies will elucidate the most appropriate acupuncture training and techniques, use as an adjunct and the clinical situations in which they can be best applied.

Management of Suspected Fluid Balance Issues in Participants of Wilderness Endurance Events.

Dehydration and exercise-associated hyponatremia (EAH) are both relatively common conditions during wilderness endurance events. Whereas dehydration is treated with fluids, EAH is appropriately managed with fluid restriction and a sodium bolus but can worsen with isotonic or hypotonic fluids. Therefore, caution is recommended in the provision of postevent rehydration in environments where EAH is a potential consideration because accurate field assessment of hydration status can be challenging, and measurement of blood sodium concentration is rarely possible in the wilderness. Dehydration management with oral rehydration is generally adequate and preferred to intravenous rehydration, which should be reserved for athletes with sustained orthostasis or inability to tolerate oral fluid ingestion after some rest. In situations where intravenous hydration is initiated without known blood sodium concentration or hydration status, an intravenous concentrated sodium solution should be available in the event of acute neurological deterioration consistent with the development of EAH encephalopathy.

Which patients should be transported to the emergency department? A perpetual prehospital dilemma.

OBJECTIVE: To examine the ability of paramedics to identify patients who could be managed in the community and to identify predictors that could be used to accurately identify patients who should be transported to EDs. METHODS: Lower acuity patients who were assessed by paramedics in the Perth metropolitan area in 2013 were studied. Paramedics prospectively indicated on the patient care record if they considered that the patient could be treated in the community. The paramedic decisions were compared with actual disposition from the ED (discharge and admission), and the occurrence of subsequent events (ambulance request, ED visit, admission and death) for discharged patients at the scene was investigated. Decision tree analysis was used to identify predictors that were associated with hospital admission. RESULTS: In total, 57 183 patients were transported to the ED, and 10 204 patients were discharged at the scene by paramedics. Paramedics identified 2717 patients who could potentially be treated in the community among those who were transported to the ED. Of these, 1455 patients (53.6%) were admitted to hospital. For patients discharged at the scene, those who were indicated as suitable for community care were more likely to experience subsequent events than those who were not. The decision tree found that two predictors (age and aetiology) were associated with hospital admission. Overall discriminative power of the decision tree was poor; the area under the receiver operating characteristic curve was 0.686. CONCLUSION: Lower acuity patients who could be treated in the community were not accurately identified by paramedics. This process requires further evaluation.

How Well Do We Understand Health Care Professionals' Perceptions and Needs in the Provision of Palliative Care? A Mixed Methods Study.

OBJECTIVES: Despite palliative care being standard for patients with chronic and/or life-limiting conditions, a perceived lack of clarity regarding the definition and scope of palliative care persists. We aimed to identify health care professionals' (HCPs) perspectives, education, and support needs related to palliative care provision in a large private Australian tertiary hospital. METHODS: A validated survey was administered and four focus groups were conducted with multidisciplinary HCPs. RESULTS: The survey response rate was 50% (n = 302). Although critical care HCPs scored symptom management and patient/family interaction items more highly compared with other HCPs, mean scores (<4.0) for both groups indicated participants lacked confidence to perform this aspect of care independently. Critical care HCPs were more comfortable caring for dying patients (p < 0.001) and talking to families about death (p < 0.001). Ward HCPs were more supportive of early referral to palliative care (p < 0.001). Cancer diagnoses were overestimated as common causes of death. Education needs focused on ethical issues, end-of-life communication skills, dealing with delirium, and use of the Liverpool Care Pathway. Key themes identified from the four focus groups were (1) delays or nonreferral to palliative care created considerable stress and feelings of inadequacy despite a perceived understanding of the broader definition of palliative care and (2) HCPs commonly focused on end-of-life care. CONCLUSION: Ambiguity regarding the meaning and delivery of palliative care persists in the acute care setting across disciplines. Results confirmed that innovative approaches to education and upskilling HCPs in palliative care and referral pathways is warranted.

Paramedic Checklists do not Accurately Identify Post-ictal or Hypoglycaemic Patients Suitable for Discharge at the Scene.

OBJECTIVES: The objective of this study was to assess the accuracy and safety of two pre-defined checklists to identify prehospital post-ictal or hypoglycemic patients who could be discharged at the scene. METHODS: A retrospective cohort study of lower acuity, adult patients attended by paramedics in 2013, and who were either post-ictal or hypoglycemic, was conducted. Two self-care pathway assessment checklists (one each for post-ictal and hypoglycemia) designed as clinical decision tools for paramedics to identify patients suitable for discharge at the scene were used. The intention of the checklists was to provide paramedics with justification to not transport a patient if all checklist criteria were met. Actual patient destination (emergency department [ED] or discharge at the scene) and subsequent events (eg, ambulance requests) were compared between patients who did and did not fulfill the checklists. The performance of the checklists against the destination determined by paramedics was also assessed. RESULTS: Totals of 629 post-ictal and 609 hypoglycemic patients were identified. Of these, 91 (14.5%) and 37 (6.1%) patients fulfilled the respective checklist. Among those who fulfilled the checklist, 25 (27.5%) post-ictal and 18 (48.6%) hypoglycemic patients were discharged at the scene, and 21 (23.1%) and seven (18.9%) were admitted to hospital after ED assessment. Amongst post-ictal patients, those fulfilling the checklist had more subsequent ambulance requests (P=.01) and ED attendances with seizure-related conditions (P=.04) within three days than those who did not. Amongst hypoglycemic patients, there were no significant differences in subsequent events between those who did and did not meet the criteria. Paramedics discharged five times more hypoglycemic patients at the scene than the checklist predicted with no significant differences in the rate of subsequent events. Four deaths (0.66%) occurred within seven days in the hypoglycemic cohort, and none of them were attributed directly to hypoglycemia. CONCLUSIONS: The checklists did not accurately identify patients suitable for discharge at the scene within the Emergency Medical Service. Patients who fulfilled the post-ictal checklist made more subsequent health care service requests within three days than those who did not. Both checklists showed similar occurrence of subsequent events to paramedics' decision, but the hypoglycemia checklist identified fewer patients who could be discharged at the scene than paramedics actually discharged. Reliance on these checklists may increase transportations to ED and delay initiation of appropriate treatment at a hospital.

Emergency department 'undercrowding' is associated with decreased waiting times.

OBJECTIVE: To evaluate the effect of a sudden and sustained decrease in patient presentations on waiting times and other measures of workload and flow following the opening of a large, greenfields ED adjacent to our own. METHOD: A descriptive study involving all patients presenting to a private urban district hospital ED for two 60 day periods, immediately before and after the opening of the tertiary hospital ED. Changes in median waiting time, case-mix distribution, method of arrival, total admissions and total waiting time were compared pre-opening and post-opening. Non-normally distributed variables were analysed using Mann-Whitney U-tests. Categorical variables were compared using χ(2) analyses. RESULTS: Patient presentations decreased by 28% with a parallel decline in median waiting time of 15 min (from 26 to 11 min) (P < 0.001). Total waiting time was approximately 29 h less per day in the post-opening period. Patient urgency by triage category did not change significantly (P = 0.316), whereas the proportion of presentations by ambulance decreased 15.9% (P = 0.048) and admission rate increased from 29.1% to 32.6% (P = 0.002). CONCLUSIONS: Patient presentation numbers are strongly associated with and likely impact on median waiting time. Understanding that controlling demand can lead to significant benefits in patient processing, flow and overall patient perceived level of care and satisfaction is relevant to any discussion on ED overcrowding and the deleterious effects of access block.

Is it Appropriate for Patients to be Discharged at the Scene by Paramedics?

BACKGROUND: Outcomes of patients who are discharged at the scene by paramedics are not fully understood. OBJECTIVE: We aimed to describe the risk of re-presentation and/or death in prehospital patients discharged at the scene. METHODS: We conducted a retrospective cohort study using linked ambulance, emergency department (ED), and death data. We compared outcomes in patients who were discharged at the scene by paramedics with those who were transported to ED by paramedics and then discharged from ED between January 1 and December 31, 2013 in metropolitan Perth, Western Australia. Occurrences of subsequent ambulance requests, ED attendance, hospital admission and death were compared between those discharged at the scene and those discharged from ED. RESULTS: There were 47,330 patients during the study period, of whom 19,732 and 27,598 patients were discharged at the scene and from ED, respectively. Compared to those discharged from ED, those discharged at the scene were more likely to subsequently: request an ambulance (6.1% vs. 1.8%, adjusted odds ratio [adj OR] 3.4; 95% confidence interval [CI] 3.0-3.9), attend ED (4.6% vs. 1.4%, adj OR 3.3; 95% CI 2.8-3.8), be admitted to hospital (3.3% vs. 0.8%, adj OR 4.2; 95% CI 3.4-5.1). Those discharged at the scene tended towards an increased likelihood of death (0.2% vs. 0.1%, adj OR 1.8; 95% CI 0.99-3.2) within 24 hours of discharge compared to those discharged from ED. CONCLUSION: Patients attended by paramedics who were discharged at the scene had more subsequent events than those who were transported to and discharged from ED. Further consideration needs to be given to who is suitable to be discharged at the scene by paramedics.

Applying palliative care principles and practice to emergency medicine.

Only recently has the potential (unmet) palliative care (PC) workload in the ED been recognised. While confident in PC symptom management, we underestimate the role of a palliative approach in non-cancer diagnoses and seek education in areas such as individual patient care pathways, ethical and legal issues and difficult conversations at the end of life. PC is best introduced early for a range of life-limiting cancer and non-cancer diagnoses. Allowing patients time to tell their story with active listening, acknowledgement of suffering and a compassionate presence leads to treatment 'success' that is not defined by cure. This patient-centred, rather than disease-centred approach, is the essence of PC, and one that is easily incorporated into emergency practice. PC and disease-specific treatments can comfortably coexist, and with meticulous symptom management, may actually prolong life. PC is everyone's business, and emergency medicine needs to be part of it.

Staff perceptions of palliative care in a public Australian, metropolitan emergency department.

OBJECTIVE: The primary aim was to investigate staff experiences and attitudes towards palliative care provision in a public metropolitan ED. METHODS: Using a previously validated survey tool, data were collected from ED clinical staff using Likert-type, open-ended and dichotomous items asking about perceptions of palliative care and education needs. Comparisons were made between nursing and medical staff. RESULTS: Medical staff and nurses' perceptions of palliative care were similar, differing on only 10 of 37 (Likert) items. All staff reported confidence with symptom management, whereas medical staff felt more confident with decision-oriented communication and nurses were more supportive of nasogastric feeding. Staff were moderately accurate in determining the five most common causes of death. Four out of five conditions selected as appropriate for palliative care were cancer diagnoses. End-of-life communication and ethical issues were the two most frequently requested areas for further education. CONCLUSIONS: Our study suggests that overall ED staff were confident regarding symptom management in palliative care. Cancer diagnoses were overrepresented in both the top five causes of death and conditions most appropriate for a palliative approach, suggesting that staff might underestimate the role of a palliative approach in non-cancer diagnoses. Areas suggested for further education include communication and ethical issues surrounding end-of-life care.
