The effectiveness of primary care services located within EDs - optimising streaming
The comprehensive review by Ramlakhan et al of the effectiveness of primary care services located within EDs draws mixed conclusions. Whilst initial efficiency savings were identified (both in terms of GP resource utilisation and overall cost) and subsequent hospital admission and referrals appeared reduced, other outcomes proved disappointing or at best equivocal including length of stay, waiting time and patient satisfaction.
Given the ongoing critical performance challenges faced by hospitals, that not only derive from increasing volumes of attendance (whether through provider-induced demand or otherwise) but also the effect consequently imposed by inefficiencies and the internal degradation of pathways, Emergency Departments need to do something radical. The crucial importance of optimising hospital productivity legitimises the use of novel streaming services that aim both to minimise the effect on the hospital of low acuity patients and, specifically, to de-bulk ED Majors attendance. If a streaming service is to be used, then the same article's review by Abdulwahid et al identifies the positive impact of senior doctor assessment at triage. In contrast to the mainly senior ED clinicians that were reviewed in this paper, our own belief is that senior GPs have a better chance of deflecting or re-directing potential admissions, not least because of clinician awareness of community-based options for care.
The introduction of a streaming service to the front door of Leicester Royal Infirmary (Europe's busiest ED) has aimed to achieve success using immediate clinical assessment by a senior GP on arrival followed by rapid assessment using 3 other streaming GPs. In a 6 month period this small team managed to treat or redirect 19% of all day time walk in patients that presented (equating to 16,094 patients per year not entering hospital) while only admitting 5% of patients to ED Majors. This scale of success in streaming can result in significant performance advantage for the hospital, both effectively redirecting patients that could be cared for elsewhere and optimising use of internal pathways and thereby improving efficiencies.

The diagnostic difficulties of lunate and perilunate dislocations.
I read with interest your recent case report of a perilunate dislocation. This case highlights the importance of careful assessment of often complex wrist X-rays. As a small point, I would however disagree that the 'spilled teacup sign' is a sign of a perilunate dislocation. This sign is a radiological sign of a lunate rather than perilunate dislocation. The key to distinguishing between between both is to first determine what is centred over the radius on the lateral view. If the capitate is centred over the radius and the lunate is tilted out with the 'spilled teacup' sign, a lunate dislocation is diagnosed. If the lunate centres over the distal radius and the capitate is dorsal, a perilunate dislocation is diagnosed, as your case illustrates.

POLST CAn Help Paramedics with End-of-Life Dilemmas
Murphy-Jones and Timmons described paramedics' experiences of end-of- life decision making with regard to nursing home residents, including the challenges faced by paramedics when patients lacked decision making capacity and the resultant stress from uncertainty about appropriate treatments.  Among the solutions suggested, an essential, straightforward and well-tested tool for the perplexed paramedic was not available to EMTs in London. Emergency medical providers in the United States report that that Physicians Orders for Life-Sustaining Treatment (POLST) Paradigm forms both increase the likelihood that the wishes of patients with advanced illness and frailty will be honored and decrease the family and health professional angst of end-of-life decision-making in moments of crisis. POLST orders have been shown to be effective in providing clear instructions to emergency medical providers and in making sure patient wishes at end-of-life are honored -- whether for comfort care or more intensive treatment.    The POLST Paradigm is an approach to end-of-life planning for those with advanced illness through a process of shared decision-making between a patient and his/her health care professional. As a result of these conversations, patient wishes are documented in a POLST form,  which translates the shared decisions into actionable medical orders, indicating a patient's wishes regarding treatments that are commonly used in a medical crisis. As a medical order, emergency personnel - such as paramedics, EMTs, and emergency physicians - must follow these orders in the absence of other information. The orders address preferences regarding cardiopulmonary resuscitation (CPR), other medical interventions such as intubation and mechanical ventilation, and artificially administered nutrition. The orders are signed by a physician (and is some jurisdictions a nurse practitioner or physician assistant) with the concurrence of the patient or legally recognized decision maker. The POLST form is distinctive, often brightly colored and can be displayed prominently so that it can be easily identified by the emergency medical personnel. The POLST Paradigm has been successfully implemented in the vast majority of states in the US, and is being adopted in a growing number of countries. We encourage health systems to adopt and emergency medical providers who care for patients at the end-of-life to learn more about the POLST Paradigm and how it can provide medical orders and direction when an emergent situation faces providers, patients and families.

Designing urgent primary care centres located at hospital sites: the devil is in the details
We have read with great interest the review of Ramlakhan et al. (2016)1 on the effectiveness of co-locating emergency departments (ED) and primary care centres and the findings of the authors that the evidence is inconclusive. Yet, we are confident that there are more hints and clues in the available evidence for policy guidance than was done in the paper by Ramlakhan et al. (2016). We will illustrate this with a recent policy analysis carried out in Belgium.2 As Burke (2016)3 states in his editorial it is key to determine the goals of your policy intervention (e.g. improved access; improved flow; reduced costs; improved patient satisfaction) and to monitor the implementation of new models. That is exactly what we have proposed by recommending a 'proof of concept evaluation' for 24/7 GP posts that are co-located with the ED (with one entrance and a joint triage area) in order to substitute ED care by primary care. Indeed, substituting more expensive ED resources by primary care resources seems a legitimate policy goal. Belgium has a very high self-referral rate (71%) and a large share of ED contacts are ambulatory contacts (77%). Furthermore, estimates of inappropriate ED contacts (40-56%) are higher than the internationally reported figures of 20-40%.4 As in other countries there is an ever increasing use of EDs which is in Belgium mainly observed for ambulatory and self-referred ED contacts. In addition, previous policy measures such as large investments in out-of-hours GP posts were unsuccessful in stopping this increasing trend. Most of these out-of-hours GP posts were not located at hospital sites. In the rare occasions where a GP post was co-located with an ED they had separate entrances and triage zones not resulting in substitution.5 Why did our policy recommendation to install GP posts on ED-sites deviate from the inconclusive findings in the Ramlakhan et al. (2016) review? Our review of the literature showed that 'design elements' are essential for successful substitution of ED care by primary care. We believe that these design elements are insufficiently analysed in the Ramlakhan et al. (2016) study. In their review several divergent models of co-location were assessed simultaneously (e.g. nurse-led walk-in clinics instead of GP-lead urgent care centres; models with separate entrances and triage areas for the primary care centre and the ED instead of one central entrance and joint triage area; or even models without a triage function). When analysing these studies more in-depth, it is clear that these design elements are making the difference in substituting ED by primary care. Indeed, 'the devil is in the details'. A difference in prescriptions of medical imaging and laboratory tests can, for instance, be observed when the initial triage process was carried out by trained nurses while this was not the case when triage was done by a receptionist. Moreover, three recent studies which were not included (van Gils-van Rooij (2015)6 for the Netherlands; Cowling et al. (2016)7 for England; Eichler et al. (2014)8 for Switzerland) showed that: a co-location of GP posts with one entrance and joint triage area is effective in reducing the number of self-referred ED contacts; the largest portion of contacts triaged towards the GP does only require care from the GP; and that GPs prescribe less medical imaging and lab tests compared to emergency physicians. We also acknowledge that the literature is not straightforward. Indeed, several reviews9 10 illustrated that an expansion of the available services might unmask latent demand and will increase the overall burden on the emergency care system even more. However, it cannot be concluded from the available studies that this increase in activity is caused by overuse (e.g. shift from regular GP contacts towards urgent care centres) nor by underuse. To account for these and other potential unintended effects we recommend a 'proof of concept' evaluation where these (un- )intended are carefully monitored.

Primary care services located with EDs: Effectiveness depends on matching patients to the right clinician
We read with interest the paper by Ramlakhan et al (10.1136/emermed- 2015-204900) on the effectiveness of primary care services located in EDs. We have just completed a test cycle week of a GP led model for managing lower acuity patients who present to the Clinical Decisions Unit (CDU) at the Glenfield Hospital, Leicester; however, we reached different conclusions. The CDU is a cardiorespiratory unit that receives mixed acuity urgent patients 24 hours a day from a range of sources (999 ambulance, GP referrals and transfers from both the local ED department and Urgent Care Centre located on the same site two miles away), but not self-referrals. The specialist teams are unable to rapidly manage and discharge low acuity patients because the hospital processes and IT systems were not designed for this purpose, resulting in overcrowding and inefficiency. A GP/specialist nurse 'fast track' area was created to rapidly diagnose (with access to chest x-ray and bloods), and discharge safely, all patients triaged by experienced nurses at the 'front door' as potentially fit for same day discharge using the primary care IT system (SystmOne). 67 patients comprising approximately 30-40% of total attendances were seen and 88% were discharged (mean of 116 minutes compared with up to 6 hours at peak periods of activity). No adverse events or seven day readmissions have been reported. Both patient and staff satisfaction was high. The overall proportion of patients who left the department in less than 6 hours (throughput/flow) increased by around 10% easing pressure on specialists who could then focus on the sicker cohort of patients. GPs handle low acuity problems faster because that fits in with their training and skill set (they appraise rapidly and decide). It is a matter of 'right patient in front of the right clinician'. We are planning a further eight week pilot to consider the cost effectiveness of our model, greater integration with the local urgent care system and the best clinician to triage on arrival.

Bland-Altman comparison of haemodynamic monitoring methods; not simply a matter of black and white.
This comparison of non-invasive haemodynamic devices, although valuable, demonstrates some methodological aspects of the Bland-Altman method that should be considered to ensure the accuracy of any proposed conclusions.
The statistical minimum for comparison of two medical device measurement methods includes reporting mean ?SD values for both methods, correlation, and Bland-Altman bias and precision, mean % differences between methods, and concordance analysis using four quandrant plots if haemodynamic changes were measured in the same subjects during the repeated observations.(1) Of critical importance for application of Bland- Altman statistics is the range of outputs over which the comparison was made. Repeated measures comparing CO values within a narrow "normal range" provide little useful information,(2) as the mean differences between measures will be small and discrimination will be weak. Additionally it is at high and low outputs that accuracy is the most critical and clinically consequential.
The authors observed USCOM measures were "considerably" lower than NICCOMO measures, which were similar to the values they expected. However the clinical characteristics of the patients are not described, the mean CO and SVR values or SD were not reported, and no quantitative Bland- Altman values nor CO ranges presented. Further upon proposing disagreement between the two methods, no reference was made to normal USCOM reference values.(3) If any differences existed between the USCOM reference normal values and the USCOM Green study normal values, then operator error may have affected the results, and the disagreement is explained, and the conclusion prefaced with an "in our hands" caveat. Conversely, if the USCOM values by Green et al. agreed with the previously published normal USCOM values, and the patient cohorts were substantially clinically matched, then the conclusion is an error in the measurements by NICCOMO, a possibility not raised by the authors.
Regardless, this comparison of repeated measures in a single series of subjects is only designed to demonstrate agreement between two methods, and not determine which technology is the most reliable, particularly if the endpoint is attainment of arbitrary and undefined expected values. Clinical accuracy is related to a more extensive and rigorous series of comparisons and proofs involving multiple animal and human studies and comparisons across a range of age groups and clinical applications, and across wide ranges of cardiac outputs against multiple technologies.
Doppler ultrasound has a long history of reliability and clinical utility for flow measurements.(4) The USCOM 1A, a transcutaneous Doppler monitoring technology has been validated against flow probes in animals across a 6 fold range of outputs during application of inotropes and vasopressors,(5) and from 0.12L/min to 18.7L/min in humans.(6,7) It has been validated against invasive standards and non-invasive standards in approximately 100 studies, and found to provide reliable measures across a range of outputs and ages.(8,9,10) It has been demonstrated to reliably measure CI and SVI and detect fluid responsiveness with approximately 90% sensitivity in patients with AF, free breathing and ventilated patients, patients on vasoactive and particularly those with dynamic circulation such as those with sepsis and septic shock where the autonomic nervous system is active.(11) Further the device is recommended in the paediatric sepsis guidelines as a means of monitoring disease progress and titration of therapy,(12) improves outcomes in paediatric septic shock,(13) and has been recommended as a pregnancy monitoring method for early detection of pre-eclampsia.(14)
Hodgson et al.,(15) compared inter-rater reliability of stroke volume measurements at baseline and following passive leg raising measurements, by emergency physicians and found a 6% error (r=0.96) between measures by different operators and concluded that "following a training period of less than 5 h, USCOM stroke volume measurements demonstrated excellent inter-rater reliability". This confirmed the feasibility of the USCOM technology in the emergency setting, an assessment not completed in the current study despite the title.
So the USCOM is comprehensively validated, while NICCOMO is a test technology, and its disagreement with USCOM suggests further evaluation in animals and humans, across a wide range of outputs and diseases is required before its utilisation could be countenanced in emergency medicine.
Comparison of method studies are technically difficult, and involve establishing a reference standard, USCOM, and then comparing paired measures from a proposed test technique, NICCOMO, acquired under identical conditions. Bland-Altman comparison can only determine if the two methods agree or disagree.(2) If the comparison demonstrates disagreement, as the authors propose, then the appropriate scientific conclusion is that, as the reference method has superior validation and clinical proof, the test method doesn't agree with the reference method "in our hands", and is therefore not valid. However additional studies of any new technology may be worthwhile if a suspicion of occult potential clinical utility persists.

Paediatric Early Warning Scores: Acute Paediatrics' Cinderella's Slipper
Paediatric Early Warning Scores: Acute Paediatrics' Cinderella's Slipper
Lillitos et al are to be congratulated on a most helpful paper clarifying whether disease severity and the need for hospital admission can be predicted using two similar PEWS systems (Brighton PEWS and COAST - the Children's Observation And Severity Tool).
There has been a proliferation in the uptake and usage of Paediatric Early Warning Scores (PEWS) in recent years, as part of the patient safety agenda. Their original (dare I say, intended) purpose was to detect early deterioration in hospitalised children, prompting timely interventions and predicting the need for possible Paediatric Intensive Care admission whereas increasingly, PEWS are being employed generically in paediatric practice in the UK. Like Cinderella's slipper (following the spirit of this season), Early Warning systems are attractive, colourful and everybody wants to claim them for their own, with Ambulance Call Response/Prioritisations, Hospital Admissions, ED Triage Systems, Telephone Triage and Decision Making algorithms, Minor Injury/Walk-in centres (to name but a few potential suitors) all seeking to shoe-horn their patient's demographics into one of the currently available scoring systems, in some situations avoiding the need for proper face-to-face clinical assessment.
Of particular importance was the author's subdivision of presenting complaints into both minor and significant "Medical" and "Surgical" conditions which highlights some of the limitations of Early Warning Scores.
It is reassuring to find that both the Brighton and COAST scores were good at detecting significant respiratory illnesses, (Brighton and COAST ROC scores yielding AUCs of 0.9 and 0.87, respectively). Whilst intended to be universally applicable, both these scores have an inherent respiratory design-bias, measuring multiple respiratory parameters (respiratory rate, moderate-severe respiratory distress, supplemental oxygen (Brighton), hypoxia (saturations ?92% in air (COAST))), both expected and desirable qualities given the prevalence of respiratory illness encountered in acute "paediatric practice" (asthma/wheeze, bronchiolitis, croup, URTI, LRTI etc.)
Importantly, both local and regional experience and reviews of adverse incidents, morbidity and mortality have anecdotally found PEWS scores to be less reliable in the early detection of neurological conditions, surgical conditions and blunt and penetrating trauma (where compensatory mechanisms delay physiological abnormalities until disease progression has advanced) and again the authors should be thanked for quantifying these reported observations (they describe AUC's of i) 0.48AVERAGED for significant neurology, 0.56 for general surgical conditions, 0.65 for significant trauma and 0.7 for head injury; Table 3). (I suspect that in major trauma, simple descriptors such as "fall from height", "ejected through windscreen" might well outperform medical COAST/PEWS systems).
The study also validates what has been termed the "currency of COAST" - that a high COAST score (a score ?3) must be taken seriously. (Due to the score's poor specificity, the converse is not true - a low score does not exclude significant illness/the need for admission). By choosing to use the PEWS/COAST score at Triage, the authors were reliant solely on abnormal physiological findings at one isolated point in time (influenced by external factors such as crying and fever etc.) whereas tracking scores over a period of observation or on an admissions/inpatient wards may have revealed the trends of deterioration described in the early papers that supported the introduction of PEWS systems (1). Even so, like other clinical descriptors (e.g. haemorrhagic rash, shock, unresponsive, fitting) the chosen individual trigger parameters would be expected to prompt an appropriate nursing/medical response e.g. this child's heart rate is abnormally high, their respiratory rate is depressed, their conscious level diminished etc. (Previous authors have discussed the possible merits of using aggregate weighted scores rather than single clinical parameters but neither approach has been found to be superior to the other (2); aggregate scores are certainly more complex, less user- friendly and suggest a knowledge and appreciation of disease processes that - if universal- is at best, currently poorly understood i.e. what happens to "normal" heart rates in an unwell/injured 5-year old as their condition progresses).
One of the study's shortcomings was to "wrongly" assign each child with a universal score of "1" for parental concern, "on the basis that parents/carers, by bringing their child to the ED, were by default concerned". Parents do sometimes make uninformed choices when presenting to ED; 60% of parents whose children had ATS (Australasian Triage System) category 4 and 5 scores described the severity of their child's illness as the primary (or secondary) reason for ED attendance (3). The intension behind the "Doctor/Nurse/Family concern" trigger was to appreciate the importance of gut feelings - something subjective, often unquantifiable and unmeasurable - to prompt an appropriate clinical response. (Van den Bruel, A et al's paper helpfully supports this approach (4)). [Within the confines of a retrospective study, the authors can legitimately claim that they unfortunately had no alternative]. As an advocate of PEWS scores (I adapted and designed the COAST chart, with permission, from the original NHS Institute for Innovation & Improvement's PEWS chart, in 2010), I do question how often these scoring systems have identified a child that would not otherwise have been identified and am concerned that, in the headlong rush to employ a PEWS system in any and every clinical setting, their value has been overstated at the expense of comprehensive nursing observations and medical assessments. They do most certainly i) have an important role to play in ensuring deteriorating trends are appreciated, communicated and acted upon by nursing and medical teams and ii) can be useful when used as a safety netting tool but, paraphrasing social media, might I suggest that we....

Air ambulance tasking: mechanism of injury, telephone interrogation or ambulance crew assessment?
We wish to thank Wilmer et al for their recent article "Air ambulance tasking: mechanism of injury, telephone interrogation or ambulance crew assessment", which we read with interest. As researchers in the field of triage we feel it raises a number of interesting questions. We believe that there are considerable similarities between triaging for enhanced trauma team despatch (eg LAA) and effective triage for direct transfer to a Major Trauma Centre (MTC). It could be reasonably suggested that those requiring treatment at a MTC would benefit from a LAA response and indeed be the target population.
We would welcome some further clarification which we feel would strengthen this work and assist with further research in the field.
Although MOI has historically been used as a dispatch criterion due to "a high rate of serious injury", the authors conclude that it is the least accurate method of tasking. We wonder if it is possible to clarify the injury patterns amongst patients identified via MOI, particularly injury severity and life-saving interventions performed by LAA.Are the authors able to identify whether any of the six MOI criteria are more accurately predictive than others? We are not aware of any such study in the literature and this could greatly benefit the MOI criteria for MTC triage.
We note that the authors' findings of 31% overtriage and 19% undertriage are amongst the closest described to the US field triage guidelines tolerance for over and under triage (up to 35% and 5% respectively)1. . Clearly a decision must always be made as to the trade- off between minimising either over or under triage. The authors describe a number of risks of over triage and this is indeed correct, a linear relationship between over triage and critical mortality has indeed been shown2. This is often over looked, with the harmful effects of under triage being the most obvious. With that in mind, we would be interested to see more information on those patients who were under triaged in this study, particularly their MOI. Can the automatic despatch criteria be further refined by looking at these under triaged patients?
We welcome the authors' response and their views on using this work as a foundation to optimise MTC triage decisions.

Preparing medical students for the front line: experiences from a curricular innovation in Ireland
We read with interest the article by Seligman and colleagues (1) which evaluated a novel first responder scheme for medical students as a collaborative venture between a medical school and the local ambulance service. Previous authors have advocated the early introduction of Emergency Medical Technician teaching in an undergraduate medical curriculum in the United States.(2) We would like to report our experiences in delivering an innovative special study module (SSM) in pre- hospital emergency care (PHEC), which has consistently been one of the most popular elective modules offered to the preclinical medical students at our institution.
The PHEC SSM was designed by senior medical educators in partnership with paramedics and advanced paramedics at our local hospital. Our university has conferred honorary clinical fellowships on the paramedic supervisors involved. Second year students complete the SSM over a 10-week period in small groups of 12 students as part of their core medical professionalism module. Participants actively shadow ambulance crews on emergency calls and assist in patient assessment, monitoring and hand-over in the emergency department, under the supervision of experienced paramedics. Students have the opportunity to consolidate their theoretical knowledge and practise procedural skills such as blood pressure measurement, capillary blood glucometry, electrocardiography and oxygen administration in an authentic clinical environment. They also become familiar with standardised emergency management, first aid, and patient safety protocols. Students maintain a reflective log of their emergency calls and are debriefed in the case of traumatic incidents. Assessment involves a combination of supervisor-led student evaluation, and submission of a written assignment based on a contemporary emergency medicine topic. Students also deliver a group presentation in which they are required to critically analyse the efficiency of the ambulance service and compare it to international best practice.
The PHEC SSM provides a formative early introduction to immediate care and emergency medicine and it focuses students' attention on the realities of clinical practice outside of a hospital setting. SSMs such as this are a useful vehicle for fostering greater inter-professional learning opportunities and improving communication between members of a multidisciplinary clinical team, as well as promoting a deeper appreciation for team-working and the ethical dilemmas of patient care. Some medical students will also benefit from being motivated towards a future career in emergency medicine. This educational intervention has greatly facilitated collaboration between the ambulance service, emergency department and the medical school, and we propose that it may serve as a model of good practice for other higher educational institutions. Consideration should be given to ultimately integrating this clinical placement into the core undergraduate medical curriculum.

Conflict of Interest:
Encouraging task-orientated coping mechanisms
This article by Howlett et al. makes for interesting reading as a junior doctor at the start of Emergency Medicine training.
This study suggests that in order for trainees (and Consultants) to maintain successful, long, enjoyable and fruitful careers, and avoid 'burnout', we should develop 'task-orientated coping' mechanisms. Currently one may argue that this is encouraged via personal reflection in the e-portfolio, may I suggest that a more collective approach is called for.
The Emergency Medicine training programme dictates that one must learn to reflect regularly and use this reflection to direct self-learning and 'learn from our experiences'. The e-portfolio is relatively rigid in how one must reflect: 'What you did', 'What would you do differently and why', 'what have you learnt', and does not necessarily encourage timely discussion with a senior colleague.
Trainees should be encouraged to discuss learning points from an experience with their Clinical/Educational Supervisor or another senior colleague. In the busy Emergency Department environment this cannot happen as frequently as it may be required and one way to combat this may be achieved through changing staff members' attitudes to the importance of reflection.
Whilst our main focus is patient care, we must acknowledge that in order to continue to provide excellent care for our patients, we need to care for ourselves and ensure that we do address issues that arise in a timely matter. All doctors will make mistakes over their career with differing impacts on patient outcome. Open discussions regarding mistakes made by clinicians at different levels will encourage all doctors to reflect and discuss issues they have been involved with and improve learning from these experiences.
Furthermore perhaps 'task-orientated coping' mechanisms should be included in the Undergraduate medical curriculum to encourage this practice from the outset for newly qualified doctors.
