BMC Emerg Med 2023; 23:65.

Abstract
BACKGROUND Out-of-hospital Emergency Medical Services (OHEMS) require fast and accurate assessment of patients and efficient clinical judgment in the face of uncertainty and ambiguity. Guidelines and protocols can support staff in these situations, but there is significant variability in their use. Therefore, the aim of this study was to increase our understanding of physician decision-making in OHEMS, in particular, to characterize the types of decisions made and to explore potential facilitating and hindering factors. METHODS Qualitative interview study of 21 physicians in a large, publicly-owned and operated OHEMS in Croatia. Data was subjected to an inductive content analysis. RESULTS Physicians (mostly young, female, and early in their career), made three decisions (transport, treat, and if yes on either, how) after an initial patient assessment. Decisions were influenced by patient needs, but to a greater extent by factors related to themselves and patients (microsystem), their organization (mesosystem), and the larger health system (macrosystem). This generated a high variability in quality and outcomes. Participants desired support through further training, improved guidelines, formalized feedback, supportive management, and health system process redesign to better coordinate and align care across organizational boundaries. CONCLUSIONS The three decisions were made complex by contextual factors that largely lay outside physician control at the mesosystem level. However, physicians still took personal responsibility for concerns more suitably addressed at the organizational level. This negatively impacted care quality and staff well-being. If managers instead adopt a learning orientation, the path from novice to expert physician could be more ably supported through organizational demands and practices aligned with real-world practice. Questions remain on how managers can better support the learning needed to improve quality, safety, and physicians' journey from novice to expert.

Abstract
In the Emergency Medical Service Acts of the Federal States, the statements in these Acts have so far essentially been limited to the implementation of measures to maintain the health of emergency patients and to transport them to a suitable hospital. Preventive fire protection, on the other hand, is regulated in the Fire Brigade Acts or by statutory ordinances. Increasing numbers of emergency service missions and a lack of facilities for alternative care justify the need for a preventive emergency service. This includes all measures that take place before an event occurs in order to prevent emergencies from occurring. As a result, the risk of an emergency event leading to the emergency call 112 should be reduced or delayed. The preventive rescue service should also help to improve the outcome of medical care for patients. Furthermore, it should be made possible to provide those seeking help with a suitable form of care at an early stage.

Abstract
Emergency Medical Service (EMS) alternative destination programs may lead to improved care quality among those experiencing mental health crises but the association with cost and emergency department (ED) recidivism remains unexamined. We compare rates of post-discharge health services use and Medicaid spending among patients transported to an ED or community mental health center (CMHC) finding higher ED recidivism for patient treated in the ED, compared to those treated in a CMHC (68% vs 34%, p < 0.001). There were no differences in Medicaid spending or health services use post-discharge suggesting EMS-operated alternative destination programs may be cost-neutral for Medicaid programs.

Abstract
Introduction Telemedicine has the potential to ease emergency department (ED) overcrowding, improve ED throughput, and decrease the cost of medical care. Much of the current knowledge of telemedicine systems focuses on bringing more specialty care to the ED or improving access in rural areas. Limited research exists on patients’ perception of telemedicine in an urban ED. Methods A survey exploring perceptions of telemedicine encounters was distributed to both providers and patients following mirrored encounters between October 2015 and August 2016. Chi-square analysis was conducted to identify associations between factors and openness to telemedicine from the patients’ perspective. Results A total of 174 patients were included in the analysis. Factors associated with patient willingness to try telemedicine included: having access to a tablet with internet (p=0.0023), having access to a tablet with camera (p=0.0025), having downloaded apps in the past (p=0.0028), having used an app in the past (p<0.0001), and had frequent video chat in the past (p=0.0142). Conclusion With widespread access to smartphones with internet connectivity and pressing demands for healthcare services, telemedicine may provide a potential solution to low acuity medical care needs.

A survey of general practitioner's opinion on the proposal to introduce 'treat and referral' into the Irish emergency medical service. Ir J Med Sci 2020; 189:1457-1463. [PMID: 32307690 DOI: 10.1007/s11845-020-02224-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2020] [Accepted: 03/27/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND The introduction of treat and referral by ambulance practitioners is under active consideration in Ireland. The Irish ambulance services have traditionally transported all patients following an emergency (112/999) call to an emergency department. The introduction of treat and referral will present a significant care pathway change. AIMS To engage GPs in relation to the proposed introduction of treat and referral. METHODS A postal survey of 50 general practices in the southeast of Ireland was completed in 2019 to identify their opinion on the introduction of treat and referral. Descriptive statistics were calculated, and Pearson's chi-square tests were used to identify statistically significant differences among GP cohorts. RESULTS A 78% response rate was achieved. Respondents indicated that informal treat and referral was practised by 40% of GPs. A significant majority of GPs indicated that their patients with diabetes or epilepsy would benefit from treat and referral and were happy for paramedics to make appointments posthypoglycaemia or seizure. There was no clear consensus in relation to confining treat and referral to adults only. Barriers to the implementation of treat and referral were a significant issue for GPs. CONCLUSIONS GPs are in the main supportive of the introduction of treat and referral; however, they have identified several barriers that may inhibit successful introduction. Importantly, a GP appointment within 48 h does not appear to be a barrier. The adequacy of the working relationships between GPs and the ambulance service and its practitioners appears to have reduced since 2006, which is concerning.

Abstract
BACKGROUND The Irish ambulance services have traditionally transported all patients following an emergency (112/999) call, regardless of acuity, to an emergency department (ED). A proposal to introduce Treat and Referral, an established care pathway in some jurisdictions, is under active consideration in Ireland. This will present a significant change. Stakeholder engagement is recognised as an essential component of management of such change. This study has conducted a multicentre, cross-sectional survey exploring opinions on the introduction of Treat and Referral among key Irish stakeholders; consultants in emergency medicine, paramedics and advanced paramedics. METHODS Public-sector consultants in emergency medicine (EM), registered paramedics and advanced paramedics, in Ireland at the time of the study, were invited to complete an on-line survey. RESULTS A significant finding was that 90% of both cohorts (EM consultants and registered paramedic practitioners) support written after-care instructions being given to referred patients, that > 83% agree that Treat and Referral will reduce unnecessary ambulance journeys and that 70% are in favour of their own family member being offered Treat and Referral. Consensus was reached between respondents that Treat and Referral would improve care and increase clinical judgement of practitioners. Differences were identified in relation to the increased availability of ambulances locally, that only adults should be included, and that research was required to extend Treat and Referral beyond the index conditions. There was no consensus on whether general practitioners (GPs) should be directly informed. CONCLUSIONS This study identified that the Irish healthcare practitioners surveyed are supportive of the introduction of Treat and Referral into Ireland. It also affords healthcare policymakers the opportunity to address the concerns raised, in particular the clinical level which will be targeted for inclusion in this extended scope of practice.

Abstract
PURPOSE Patient triage to the appropriate destination is critical to prehospital trauma care. Triage decisions are challenging in a region without collocated pediatric and adult trauma centers. METHODS A regional survey was administered to emergency medical response units identifying variability and confusion regarding factors influencing patient disposition. A course was developed to guide the triage of pediatric and pregnant trauma patients. Pre- and posttests were administered to address course principles, including decision making and triage. RESULTS A total of 445 participants completed the course at 22 sites representing 88 different prehospital provider agencies. Pre- and posttests were administered to 62% of participants with an average score improvement of 53.4% (pretest range 30% to 56.6%; posttest range 85% to 100%). Improvements were seen in all categories including major and minor trauma in pregnancy, major trauma in adolescence, and knowledge of age limits and triage protocols. CONCLUSION Education on triage guidelines and principles of pediatric resuscitation is essential for appropriate prehospital trauma management. Pre- and posttests may be used to demonstrate short term efficacy, while ongoing evaluations of practice patterns and follow-up surveys are needed to demonstrate longevity of acquired knowledge and identify areas of persistent confusion.

Abstract
INTRODUCTION Necrotizing fasciitis (NF) is an uncommon but rapidly progressive infection that results in gross morbidity and mortality if not treated in its early stages. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score is used to distinguish NF from other soft tissue infections such as cellulitis or abscess. This study analyzed the ability of the LRINEC score to accurately rule out NF in patients who were confirmed to have cellulitis, as well as the capability to differentiate cellulitis from NF. METHODS This was a 10-year retrospective chart-review study that included emergency department (ED) patients ≥18 years old with a diagnosis of cellulitis or NF. We calculated a LRINEC score ranging from 0-13 for each patient with all pertinent laboratory values. Three categories were developed per the original LRINEC score guidelines denoting NF risk stratification: high risk (LRINEC score ≥8), moderate risk (LRINEC score 6-7), and low risk (LRINEC score ≤5). All cases missing laboratory values were due to the absence of a C-reactive protein (CRP) value. Since the score for a negative or positive CRP value for the LRINEC score was 0 or 4 respectively, a LRINEC score of 0 or 1 without a CRP value would have placed the patient in the "low risk" group and a LRINEC score of 8 or greater without CRP value would have placed the patient in the "high risk" group. These patients missing CRP values were added to these respective groups. RESULTS Among the 948 ED patients with cellulitis, more than one-tenth (10.7%, n=102 of 948) were moderate or high risk for NF based on LRINEC score. Of the 135 ED patients with a diagnosis of NF, 22 patients had valid CRP laboratory values and LRINEC scores were calculated. Among the other 113 patients without CRP values, six patients had a LRINEC score ≥ 8, and 19 patients had a LRINEC score ≤ 1. Thus, a total of 47 patients were further classified based on LRINEC score without a CRP value. More than half of the NF group (63.8%, n=30 of 47) had a low risk based on LRINEC ≤5. Moreover, LRINEC appeared to perform better in the diabetes population than in the non-diabetes population. CONCLUSION The LRINEC score may not be an accurate tool for NF risk stratification and differentiation between cellulitis and NF in the ED setting. This decision instrument demonstrated a high false positive rate when determining NF risk stratification in confirmed cases of cellulitis and a high false negative rate in cases of confirmed NF.
