Abstract
BACKGROUND Symptom-checkers have become important tools for self-triage, assisting patients to determine the urgency of medical care. To be safe and effective, these tools must be validated, particularly to avoid potential hazardous undertriage without leading to inefficient overtriage. Only limited safety data from studies including small sample sizes have been available so far. OBJECTIVE The objective of our study was to prospectively investigate the safety of patients' self-triage in a large patient sample. We used SMASS pathfinder, a symptom-checker based on a computerized transparent neural network. METHODS We recruited 2543 patients into this single centre, prospective clinical trial conducted at the cantonal hospital of Baden, Switzerland. Patients with an Emergency Severity Index of 1-2 were treated by the team of the emergency department, while those with an index of 3-5 were seen at the walk-in clinic by general physicians. We compared the triage recommendation obtained by the patients' self-triage with the assessment of the clinical urgency made by three successive interdisciplinary panels of physicians (Panel A, B, C). Using a Clopper-Pearson confidence interval, we assumed that in order to confirm the symptom-checkers safety, the upper confidence bound for the probability of a potentially hazardous undertriage should lie below 1%. A potentially hazardous undertriage was defined as a triage in which either all (consensus criterion) or the majority (majority criterion) of the experts of the last panel (Panel C) rated the triage of the symptom-checker to be "rather likely" or "likely" life-threatening or harmful. RESULTS Of the 2543 patients, 1227 (48.3%) were female and 1316 (51.7%) male. None of the patients reached the pre-specified consensus criterion for a potentially hazardous undertriage. This resulted in an upper 95% confidence bound of 0.1184%. 4 cases met the majority criterion. This resulted in an upper 95% confidence bound for the probability of a potentially hazardous undertriage of 0.3616%. The two-sided 95% Clopper-Pearson confidence interval for the probability of overtriage (450 cases, 17.7%) was 16.23% to 19.24%, which is considerably lower than figures reported in the literature. CONCLUSIONS The symptom-checker proved to be a safe triage tool, avoiding potentially hazardous undertriage in a real-life clinical setting of emergency consultations at a WIC/ED, whithout causing undesirable overtriage. Our data suggest the symptom-checker may be safely used in clinical routine. CLINICALTRIAL ClinicalTrials.gov identifier NCT04055298.

Clinical decision support system in emergency telephone triage: A scoping review of technical design, implementation and evaluation. Int J Med Inform 2024; 184:105347.

Abstract
OBJECTIVES Emergency department overcrowding could be improved by upstream telephone triage. Emergency telephone triage aims at managing and orientating adequately patients as early as possible and distributing limited supply of staff and materials. This complex task could be improved with the use of Clinical decision support systems (CDSS). The aim of this scoping review was to identify literature gaps for the future development and evaluation of CDSS for Emergency telephone triage. MATERIALS AND METHODS We present here a scoping review of CDSS designed for emergency telephone triage, and compared them in terms of functional characteristics, technical design, health care implementation and methodologies used for evaluation, following the PRISMA-ScR guidelines. RESULTS Regarding design, 19 CDSS were retrieved: 12 were knowledge based CDSS (decisional algorithms built according to guidelines or clinical expertise) and 7 were data driven (statistical, machine learning, or deep learning models). Most of them aimed at assisting nurses or non-medical staff by providing patient orientation and/or severity/priority assessment. Eleven were implemented in real life, and only three were connected to the Electronic Health Record. Regarding evaluation, CDSS were assessed through various aspects: intrinsic characteristics, impact on clinical practice or user apprehension. Only one pragmatic trial and one randomized controlled trial were conducted. CONCLUSION This review highlights the potential of a hybrid system, user tailored, flexible, connected to the electronic health record, which could work with oral, video and digital data; and the need to evaluate CDSS on intrinsic characteristics and impact on clinical practice, iteratively at each distinct stage of the IT lifecycle.

Abstract
In recent years, 911 call volumes have increased, and emergency medical services (EMS) are routinely stretched beyond capacity. To better match resources with patient needs, some EMS systems have integrated clinician roles into the emergency medical communications centre (MCC). Our objective was to explore the nature and scope of clinical roles in emergency MCCs. Using a rapid scoping review methodology, we searched PubMed for studies related to any clinical role employed within an emergency MCC. We accepted reviews, experimental and observational designs, as well as expert opinions. Studies reporting on dispatcher recognition and pre-arrival instructions were excluded. Title and abstract screening were conducted by a single reviewer, included studies were verified by two reviewers, and data extraction was completed in duplicate, all using Covidence review software. The level of evidence was assessed using the prehospital evidence-based practice (PEP) scale. The protocol was registered in Open Science Framework (10.17605/OSF.IO/NX4T8). Our search yielded 1071 titles, and four were added from other sources; 44 studies were reviewed at the full-text stage and 31 were included. The included studies were published from 2002 to 2022 and represent 17 countries. Studies meeting inclusion criteria consisted of level I (n=4, 11%), II (n=13, 37%), and III (N=6, 17%) methodologies, as well as 12 other studies (34%) with qualitative or other designs. Most of the included studies reported systems that employ nurses in the MCC (n=29, 83%). Twelve (34%) studies reported on the inclusion of paramedics in the MCC, and five (14%) reported physician involvement. The roles of these clinicians chiefly consisted of triage (n=25, 71%), advice (n=20, 57%), referral to non-emergency care (n=14, 40%), and peer-to-peer consulting (n=2, 4%). Alternative dispositions (as opposed to emergency ambulance transport) for low acuity callers included self-care, as well as referral to a general practitioner, pharmacist, or other outreach programs. There is a wide range of literature reporting on clinical roles integrated within MCCs. Our findings revealed that MCC nurses, physicians, and paramedics assist substantively with triage, advice, and referrals to better match resources to patient needs, with or without the requirement for ambulance dispatch.

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.

Redirecting emergency medical services patients with unmet primary care needs: the perspective of paramedics on feasibility and acceptance of an alternative care path in a qualitative investigation from Berlin, Germany. BMC Emerg Med 2022; 22:103. [PMID: 35690710 PMCID: PMC9187922 DOI: 10.1186/s12873-022-00660-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Accepted: 05/27/2022] [Indexed: 11/10/2022] Open
Abstract
Background Against the backdrop of emergency department (ED) overcrowding, patients’ potential redirection to outpatient care structures is a subject of current political debate in Germany. It was suggested in this context that suitable lower-urgency cases could be transported directly to primary care practices by emergency medical services (EMS), thus bypassing the ED. However, practicality is discussed controversially. This qualitative study aimed to capture the perspective of EMS personnel on potential patient redirection concepts. Methods We conducted qualitative, semi-structured phone interviews with 24 paramedics. Interviews were concluded after attainment of thematic saturation. Interviews were transcribed verbatim, and qualitative content analysis was performed. Results Technical and organizational feasibility of patients’ redirection was predominantly seen as limited (theme: “feasible, but only under certain conditions”) or even impossible (theme: “actually not feasible”), based on a wide spectrum of potential barriers. Prominently voiced reasons were restrictions in personnel resources in both EMS and ambulatory care, as well as concerns for patient safety ascribed to a restricted diagnostic scope. Concerning logistics, alternative transport options were assessed as preferable. Regarding acceptance by stakeholders, the potential for releasing ED caseload was described as a factor potentially promoting adoption, while doubt was raised regarding acceptance by EMS personnel, as their workload was expected to conversely increase. Paramedics predominantly did not consider transporting lower-urgency cases as their responsibility, or even as necessary. Participants were markedly concerned of EMS being misused for taxi services in this context and worried about negative impact for critically ill patients, as to vehicles and personnel being potentially tied up in unnecessary transports. As to acceptance on the patients’ side, interview participants surmised a potential openness to redirection if this would be associated with benefits like shorter wait times and accompanied by proper explanation. Conclusions Interviews with EMS staff highlighted considerable doubts about the general possibility of a direct redirection to primary care as to considerable logistic challenges in a situation of strained EMS resources, as well as patient safety concerns. Plans for redirection schemes should consider paramedics’ perspective and ensure a provision of EMS with the resources required to function in a changing care environment.

Abstract
OBJECTIVE To evaluate service use, clinical outcomes and user experience related to telephone-based digital triage in urgent care. DESIGN Systematic review and narrative synthesis. DATA SOURCES Medline, Embase, CINAHL, Web of Science and Scopus were searched for literature published between 1 March 2000 and 1 April 2020. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Studies of any design investigating patterns of triage advice, wider service use, clinical outcomes and user experience relating to telephone based digital triage in urgent care. DATA EXTRACTION AND SYNTHESIS Two reviewers extracted data and conducted quality assessments using the mixed methods appraisal tool. Narrative synthesis was used to analyse findings. RESULTS Thirty-one studies were included, with the majority being UK based; most investigated nurse-led digital triage (n=26). Eight evaluated the impact on wider healthcare service use following digital triage implementation, typically reporting reduction or no change in service use. Six investigated patient level service use, showing mixed findings relating to patients' adherence with triage advice. Evaluation of clinical outcomes was limited. Four studies reported on hospitalisation rates of digitally triaged patients and highlighted potential triage errors where patients appeared to have not been given sufficiently high urgency advice. Overall, service users reported high levels of satisfaction, in studies of both clinician and non-clinician led digital triage, but with some dissatisfaction over the relevance and number of triage questions. CONCLUSIONS Further research is needed into patient level service use, including patients' adherence with triage advice and how this influences subsequent use of services. Further evaluation of clinical outcomes using larger datasets and comparison of different digital triage systems is needed to explore consistency and safety. The safety and effectiveness of non-clinician led digital triage also needs evaluation. Such evidence should contribute to improvement of digital triage tools and service delivery.

Abstract
Introduction The Emergency Telephone Consultation Center in Tokyo (#7119) was the first telephone triage system in Japan and has operated since 2007. This study examined the revision of the #7119 protocol by referring the linked data to each code of the triage protocol. Methods We selected candidates based on the medical codes targeted by the revision, linking data from the nurses' decisions in triage and the patients' condition severity when the ambulance arrived at the hospital, gathering data from June 1, 2016, to December 31, 2017. Then, several emergency physicians evaluated the cases and decided whether the code should be moved to the more or less urgent category or if new protocols and codes would be established. Results In this revision, 371 codes were moved to the less urgent category, 35 codes were moved to the more urgent category, and 128 codes were newly established. In all, 59 red codes (transfer to the ambulance dispatcher) were reduced, while 254 orange codes (attendance at hospital within 1 hour) and yellow codes (within 6 hours) were moved to less urgent, and 12 yellow and green codes (within 24 hours) were moved to more urgent. Conclusion We adjusted the triage codes for the revision by linking the call data with the case data. This revision should decrease the inappropriate use of ambulances and reduce the primary care workload. To achieve a more accurate revision, we need to refine the process of evaluating the validity of patients' acuity over the telephone during triage.

Abstract
BACKGROUND Most calls to ambulance result in emergency ambulance dispatch (direct dispatch) following primary telephone triage. Ambulance Victoria uses clinician-led secondary telephone triage for patients identified as low-acuity during primary triage to refer them to alternative care pathways; however, some are returned for ambulance dispatch (secondary dispatch). Older adult patients are frequent users of ambulance services; however, little is known about the appropriateness of subsequent secondary dispatches. OBJECTIVES To examine the appropriateness of secondary dispatch through a comparison of the characteristics and ambulance outcomes of older patients dispatched an emergency ambulance via direct or secondary dispatch. DESIGN A retrospective cohort study of ambulance patient data between September 2009 and June 2012 was conducted. SETTING The secondary telephone triage service operated in metropolitan Melbourne, Victoria, Australia during the study period. PARTICIPANTS There were 90 086 patients included aged 65 years and over who had an emergency ambulance dispatch via direct or secondary dispatch with one of the five most common secondary dispatch paramedic diagnoses. MAIN OUTCOME MEASURES Descriptive analyses compared characteristics, treatment and transportation rates between direct and secondary dispatch patients. RESULTS The dispatch groups were similar in demographics, vital signs and hospital transportation rates. However, secondary dispatch patients were half as likely to be treated by paramedics (OR 0.51; CI 0.48 to 0.55; p<0.001). Increasing age was associated with decreasing treatment (p<0.005) and increasing transportation rates (p<0.005). CONCLUSION Secondary triage could identify patients who would ultimately be transported to an emergency department. However, the lower paramedic treatment rates suggest many secondary dispatch patients may have been suitable for referral to alternative low-acuity transport or referral options.

Abstract
OBJECTIVES This study aimed to assess whether trigger tools were useful identifying triage errors among patients referred to non-emergency care by emergency medical dispatch nurses, and to describe the characteristics of these patients. DESIGN An observational study of patients referred by dispatch nurses to non-emergency care. SETTING Dispatch centres in two Swedish regions. PARTICIPANTS A total of 1089 adult patients directed to non-emergency care by dispatch nurses between October 2016 and February 2017. 53% were female and the median age was 61 years. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome was a visit to an emergency department within 7 days of contact with the dispatch centre. Secondary outcomes were (1) visits related to the primary contact with the dispatch centre, (2) provision of care above the primary level (ie, interventions not available at a typical local primary care centre) and (3) admission to hospital in-patient care. RESULTS Of 1089 included patients, 260 (24%) visited an emergency department within 7 days. Of these, 209 (80%) were related to the dispatch centre contact, 143 (55%) received interventions above the primary care level and 99 (38%) were admitted to in-patient care. Elderly (65+) patients (OR 1.45, 95% CI 1.05 to 1.98) and patients referred onwards to other healthcare providers (OR 1.58, 95% CI 1.15 to 2.19) had higher likelihoods of visiting an emergency department. Six avoidable patient harms were identified, none of which were captured by existing incident reporting systems, and all of which would have received an ambulance if the decision support system had been strictly adhered to. CONCLUSION The use of these patient outcomes in the framework of a Global Trigger Tool-based review can identify patient harms missed by incident reporting systems in the context of emergency medical dispatching. Increased compliance with the decision support system has the potential to improve patient safety.

Abstract
Objective Ambulance-based secondary telephone triage systems have been established in ambulance services to divert low-acuity cases away from emergency ambulance dispatch. However, some low-acuity cases still receive an emergency ambulance dispatch following secondary triage. To date, no evidence exists identifying whether these cases required an emergency ambulance. The aim of this study was to investigate whether cases were appropriately referred for emergency ambulance dispatch following secondary telephone triage. Methods A retrospective cohort analysis was conducted of cases referred for emergency ambulance dispatch in Melbourne, Australia following secondary telephone triage between September 2009 and June 2012. Appropriateness was measured by assessing the frequency of advanced life support (ALS) treatment by paramedics, and paramedic transport to hospital. Results There were 23,696 cases included in this study. Overall, 54% of cases received paramedic treatment, which was similar to the state-wide rate for emergency ambulance cases (55.5%). All secondary telephone triage cases referred for emergency ambulance dispatch had transportation rates higher than all metropolitan emergency ambulance cases (82.2% versus 71.1%). Two-thirds of the cases that were transported were also treated by paramedics (66.5%), and 17.7% of cases were not transported to hospital by ambulance following paramedic assessment. Conclusions Overall, the cases returned for emergency ambulance dispatch following secondary telephone triage were appropriate. Nevertheless, the paramedic treatment rates in particular indicate a considerable rate of overtriage requiring further investigation to optimize the efficacy of secondary telephone triage.

Abstract
BACKGROUND On-scene management of pre-hospital emergencies is often inter-disciplinary, involving ground-emergency medical services (EMS), police- and fire services, and in Norway general practitioners on-call. This can also be supplemented by physician-staffed EMS (P-EMS), utilizing helicopters or rapid response vehicles. We hypothesized that P-EMS cooperates extensively with other emergency services, and therefore the primary aim of this study was to investigate the fraction of inter-disciplinary cooperation between P-EMS and other emergency services. METHODS Retrospective, observational study of primary pre-hospital missions with patient contact performed at a Norwegian P-EMS base from 01.01.06 to 31.12.15. Descriptive statistics, comparisons using Student`s t-test, and chi-squared test for trend were applied. RESULTS Inter-disciplinary cooperation occurred in 94.3% of the 8580 missions, of which physician-staffed EMS cooperated with ground EMS in 92.4%, general practitioner 32.9%, police service 11.6% and fire service 11.8%. Trauma constituted 34.4 and cardiac arrest 14.1% of missions. The mean National Advisory Committee for Aeronautics score was 4.21 (95% Confidence Interval 4.18-4.24). There was an overall decrease in cooperation with general practitioners and the police service (P < 0.001). During helicopter missions, we reported a decrease in general practitioner cooperation compared to an increase during rapid response car missions (P < 0.001). In cardiac arrest cases, cooperation with both general practitioners and the fire service increased (P < 0.001). CONCLUSION Physician-staffed EMS cooperates extensively with other professional emergency services, especially ground-EMS. On-scene cooperation with general practitioners decreased, whereas there was an increased cooperation with the fire service in a "first-responder" role during cardiac arrest missions.

Patient and case characteristics associated with 'no paramedic treatment' for low-acuity cases referred for emergency ambulance dispatch following a secondary telephone triage: a retrospective cohort study. Scand J Trauma Resusc Emerg Med 2018; 26:8. [PMID: 29321074 PMCID: PMC5763642 DOI: 10.1186/s13049-018-0475-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2017] [Accepted: 01/03/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Predicting case types that are unlikely to be treated by paramedics can aid in managing demand for emergency ambulances by identifying cases suitable for alternative management pathways. The aim of this study was to identify the patient characteristics and triage outcomes associated with 'no paramedic treatment' for cases referred for emergency ambulance dispatch following secondary telephone triage. METHODS A retrospective cohort analysis was conducted of cases referred for emergency ambulance dispatch following secondary telephone triage between September 2009 and June 2012. Multivariable logistic regression modelling was used to identify explanatory variables associated with 'no paramedic treatment'. RESULTS There were 19,041 cases eligible for inclusion in this study over almost three years, of which 8510 (44.7%) were not treated after being sent an emergency ambulance following secondary triage. Age, time of day, pain, triage guideline group, and comorbidities were associated with 'no paramedic treatment'. In particular, cases 0-4 years of age or those with psychiatric conditions were significantly less likely to be treated by paramedics, and increasing pain resulted in higher rates of paramedic treatment. CONCLUSIONS This study highlights that case characteristics can be used to identify particular case types that may benefit from care pathways other than emergency ambulance dispatch. This process is also useful to identify gaps in the alternative care pathways currently available. These findings offer the opportunity to optimise secondary telephone triage services to support their strategic purpose of minimising unnecessary emergency ambulance demand and to match the right case with the right care pathway.

Abstract
OBJECTIVE To investigate the appropriateness of cases presenting to the emergency department (ED) following ambulance-based secondary telephone triage. DESIGN A pragmatic retrospective cohort analysis of all the planned and unplanned ED presentations within 48 hours of a secondary telephone triage. SETTING The secondary telephone triage service, called the Referral Service, and the hospitals were located in metropolitan Melbourne, Australia and operated 24 hours a day, servicing 4.25 million people. The Referral Service provides an in-depth secondary triage of cases classified as low acuity when calling the Australian emergency telephone number. POPULATION Cases triaged by the Referral Service between September 2009 and June 2012 were linked to ED and hospital admission records (N=44,523). Planned ED presentations were cases referred to the ED following the secondary triage, unplanned ED presentations were cases that presented despite being referred to alternative care pathways. MAIN OUTCOME MEASURES Appropriateness was measured using an ED suitability definition and hospital admission rates. These were compared with mean population data which consisted of all of the ED presentations for the state (termed the 'average Victorian ED presentation'). RESULTS Planned ED presentations were more likely to be ED suitable than unplanned ED presentations (OR 1.62; 95% CI 1.5 to 1.7; p<0.001) and the average Victorian ED presentation (OR 1.85; 95% CI 1.01 to 3.4; p=0.046). They were also more likely to be admitted to the hospital than the unplanned ED presentation (OR 1.5; 95% CI 1.4 to 1.6; p<0.001) and the average Victorian ED presentation (OR 2.3, 95% CI 2.24 to 2.33; p<0.001). Just under 15% of cases diverted away from the emergency care pathways presented in the ED (unplanned ED attendances), and 9.5% of all the alternative care pathway cases were classified as ED suitable and 6.5% were admitted to hospital. CONCLUSIONS Secondary telephone triage was able to appropriately identify many ED suitable cases, and while most cases referred to alternative care pathways did not present in the ED. Further research is required to establish that these were not inappropriately triaged away from the emergency care pathways.

Abstract
INTRODUCTION Unscheduled reattendances at the paediatric emergency department may contribute to overcrowding, which may increase financial burdens. The objectives of this study were to determine the rate of reattendances and characterise factors influencing these reattendances and hospital admission during the return visits. METHODS Medical records of all patients who attended the emergency department at KK Women's and Children's Hospital, Singapore, from 1 June 2013 to 31 May 2014 were retrospectively reviewed. We collected data on patient demographics, attendance data and clinical characteristics. Planned reattendances, recalled cases, reattendances for unrelated complaints and patients who left without being seen were excluded. A multivariate analysis was conducted to determine the odds ratio of variables associated with hospital admission for reattendances. RESULTS Of 162,566 children, 6,968 (4.3%) returned within 72 hours, and 2,925 (42.0% of reattendance group) were admitted on their return visits. Children more likely to reattend were under three years of age, Chinese, triaged as Priority 2 at the first visit, and were initially diagnosed with respiratory or gastrointestinal conditions. However, children more likely to be admitted on their return visits were over 12 years of age, Malay, had a higher triage acuity or were uptriaged, had the presence of a comorbidity, and were diagnosed with gastrointestinal conditions. CONCLUSION We identified certain subgroups in the population who were more likely to be admitted if they reattended. These findings would help in implementing further research and directing strategies to reduce potentially avoidable reattendances and admissions.

Abstract
OBJECTIVE In Denmark, calls to the Danish emergency number 1-1-2 concerning medical emergencies are received by an emergency medical communication center (EMCC). At the EMCC, health care professionals (nurses, paramedics, and physicians) decide the necessary response, depending on the level of emergency as indicated by the Danish Index for Emergency Care. The index states 37 main criteria (symptoms) and five levels of emergency, descending from A (life threatening) to E (not serious). An ambulance is not sent to emergency level-E patients (level-E patients), but they are given other kinds of help/advice. No prior studies focusing on Danish level-E patients exist, hence the sparse knowledge about them. This study aimed to characterize level-E patients in the Central Denmark Region and to investigate their progress in the health care system after the 1-1-2 call, regarding contacting 1-1-2 again, general practitioner and Emergency Department (ED) visits, hospital admission, and death. METHODS This is a retrospective follow-up study of callers who contacted the EMCC of the Central Denmark Region and were assessed as level-E patients from August 2013 to July 2014. The study population was identified in the EMCC dispatch software, whose data were supplemented with health care data from three national registries. RESULTS Of the 53,414 patients who called 1-1-2 over the study period, 4,962 level-E patients were included in the study. The median age was 47 years (IQR: 24.3-67.7), and 53.4% were men. The most common main criteria were extremity pain - minor wounds. Within 1 day after their 1-1-2 call, 42.1% had a subsequent contact with the health care system. Of those, 5.9% called 1-1-2 again, 24.3% contacted an ED, and 8.6% were admitted. The fatality rate was 0.1%. CONCLUSIONS Level-E patients who contacted the EMCC of the Central Denmark Region were most frequently young adults. Almost 60% of level E-patients, who could be tracked, had no further contact with the health care system within a day after their 1-1-2 call. Of those who did, a quarter contacted an ED, indicating that level-E patients needed medical attention. The low fatality rates suggest limited undertriage, that is, level-E patients do not seem to need emergency medical service transportation. Further studies on undertriage among other things are needed.

Abstract
Objective The aim of the present study was to describe the Ambulance Victoria (AV) secondary telephone triage service, called the Referral Service (RS), for low-priority patients calling triple zero. This service provides alternatives to ambulance dispatch, such as doctor or nurse home visits. Methods A descriptive epidemiological review of all the cases managed between 2009 and 2012 was conducted, using data from AV case records, the Victorian Admitted Episodes Dataset and the Australian Bureau of Statistics. Cases were reviewed for patient demographics, condition, final disposition and RS outcome. Results In all, 107148 cases were included in the study, accounting for 10.3% of the total calls for ambulance attendance. Median patient age was 54 years and 55% were female. Geographically based socioeconomic status was associated with the rate of calls to the RS (r = –0.72; 95% confidence interval CI –0.104, –0.049; P < 0.001). Abdominal pain and back symptoms were the most common patient problems. Although 68% of patients were referred to the emergency department, only 27.6% of the total cases were by emergency ambulance; the remainder were diverted to non-emergency ambulance or the patient’s own private transport. The remaining 32% of cases were referred to alternative service providers or given home care advice. Conclusions This paper describes the use of an ongoing secondary triage service, providing an effective strategy for managing emergency ambulance demand. What is known about the topic? Some calls to emergency services telephone numbers for ambulance assistance consist of cases deemed to be low-acuity that could potentially be better managed in the primary care setting. The demand on ambulance resources is increasing each year. Secondary telephone triage systems have been trialled in ambulance services in the US and UK with minimal success in terms of overall impact on ambulance resourcing. What does this paper add? This study describes a model of secondary telephone triage in the ambulance setting that has provided an effective way to divert patients to more suitable forms of health care to meet their needs. What are the implications for practitioners? The implications for practitioners are vast. Some of the issues that currently face paramedics include: fatigue because of high workloads; skills decay because of a lack of exposure to patients requiring intervention with skills the paramedics have, as well as a lack of time for paramedics to practice these skills during their downtime; and decreasing job satisfaction linked to both these factors. Implications for patients include quicker response times because more ambulances will be available to respond and increased patient safety because of decreased fatigue and higher skill levels in paramedics.

Abstract
BackgroundIn 2013 NHS England set out its strategy for the development of an emergency and urgent care system that is more responsive to patients’ needs, improves outcomes and delivers clinically excellent and safe care. Knowledge about the current evidence base on models for provision of safe and effective urgent care, and the gaps in evidence that need to be addressed, can support this process.ObjectiveThe purpose of the evidence synthesis is to assess the nature and quality of the existing evidence base on delivery of emergency and urgent care services and identify gaps that require further primary research or evidence synthesis.Data sourcesMEDLINE, EMBASE, The Cochrane Library, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and the Web of Science.MethodsWe have conducted a rapid, framework-based, evidence synthesis approach. Five separate reviews linked to themes in the NHS England review were conducted. One general and five theme-specific database searches were conducted for the years 1995–2014. Relevant systematic reviews and additional primary research papers were included and narrative assessment of evidence quality was conducted for each review.ResultsThe review was completed in 6 months. In total, 45 systematic reviews and 102 primary research studies have been included across all five reviews. The key findings for each review are as follows: (1) demand – there is little empirical evidence to explain increases in demand for urgent care; (2) telephone triage – overall, these services provide appropriate and safe decision-making with high patient satisfaction, but the required clinical skill mix and effectiveness in a system is unclear; (3) extended paramedic roles have been implemented in various health settings and appear to be successful at reducing the number of transports to hospital, making safe decisions about the need for transport and delivering acceptable, cost-effective care out of hospital; (4) emergency department (ED) – the evidence on co-location of general practitioner services with EDs indicates that there is potential to improve care. The attempt to summarise the evidence about wider ED operations proved to be too complex and further focused reviews are needed; and (5) there is no empirical evidence to support the design and development of urgent care networks.LimitationsAlthough there is a large body of evidence on relevant interventions, much of it is weak, with only very small numbers of randomised controlled trials identified. Evidence is dominated by single-site studies, many of which were uncontrolled.ConclusionsThe evidence gaps of most relevance to the delivery of services are (1) a requirement for more detailed understanding and mapping of the characteristics of demand to inform service planning; (2) assessment of the current state of urgent care network development and evaluation of the effectiveness of different models; and (3) expanding the current evidence base on existing interventions that are viewed as central to delivery of the NHS England plan by assessing the implications of increasing interventions at scale and measuring costs and system impact. It would be prudent to develop a national picture of existing pilot projects or interventions in development to support decisions about research commissioning.FundingThe National Institute for Health Research Health Services and Delivery Research Programme.

Abstract
BackgroundThe role of ambulance services has changed dramatically over the last few decades with the introduction of paramedics able to provide life-saving interventions, thanks to sophisticated equipment and treatments available. The number of 999 calls continues to increase, with adverse events theoretically possible with each one. Most patient safety research is based on hospital data, but little is known concerning patient safety when using ambulance services, when things can be very different. There is an urgent need to characterise the evidence base for patient safety in NHS ambulance services.ObjectiveTo identify and map available evidence relating to patient safety when using ambulance services.DesignMixed-methods design including systematic review and review of ambulance service documentation, with areas for future research prioritised using a Delphi process.Setting and participantsAmbulance services, their staff and service users in UK.Data sourcesA wide range of data sources were explored. Multiple databases, reference lists from key papers and citations, Google and the NHS Confederation website were searched, and experts contacted to ensure that new data were included in the review. The databases MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, Science Direct, Emerald, Education Resources Information Center (ERIC), Applied Social Sciences Index and Abstracts, Social Services Abstracts, Sociological Abstracts, International Bibliography of the Social Sciences (IBSS), PsycINFO, PsycARTICLES, Health Management Information Consortium (HMIC), NHS Evidence, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (DARE), NHS Economic Evaluation Database (NHS EED),Health Technology Assessment, the FADE library, Current Awareness Service for Health (CASH), OpenDOAR (Directory of Open Access Repositories) and Open System for Information on Grey Literature in Europe (OpenSIGLE) and Zetoc (The British Library's Electronic Table of Contents) were searched from 1 January 1980 to 12 October 2011. Publicly available documents and issues identified by National Patient Safety Agency (NPSA), NHS Litigation Authority (NHSLA) and coroners’ reports were considered. Opinions and perceptions of senior managers, ambulance staff and service users were solicited.Review methodsData were extracted from annual reports using two-stage thematic analysis, data from quality accounts were collated with safety priorities tabulated and considered using thematic analysis, NPSA incident report data were collated and displayed comparatively using descriptive statistics, claims reported to NHSLA were analysed to identify number and cost of claims from mistakes and/or poor service, and summaries of coroners’ reports were assessed using thematic analysis to identify underlying safety issues. The depth of analysis is limited by the remit of a scoping exercise and availability of data.ResultsWe identified studies exploring different aspects of safety, which were of variable quality and with little evidence to support activities currently undertaken by ambulance services. Adequately powered studies are required to address issues of patient safety in this service, and it appeared that national priorities were what determined safety activities, rather than patient need. There was inconsistency of information on attitudes and approaches to patient safety, exacerbated by a lack of common terminology.ConclusionPatient safety needs to become a more prominent consideration for ambulance services, rather than operational pressures, including targets and driving the service. Development of new models of working must include adequate training and monitoring of clinical risks. Providers and commissioners need a full understanding of the safety implications of introducing new models of care, particularly to a mobile workforce often isolated from colleagues, which requires a body of supportive evidence and an inherent critical evaluation culture. It is difficult to extrapolate findings of clinical studies undertaken in secondary care to ambulance service practice and current national guidelines often rely on consensus opinion regarding applicability to the pre-hospital environment. Areas requiring further work include the safety surrounding discharging patients, patient accidents, equipment and treatment, delays in transfer/admission to hospital, and treatment and diagnosis, with a clear need for increased reliability and training for improving handover to hospital.FundingThe National Institute for Health Research Health Services and Delivery Research programme.

Abstract
AbstractObjectivesEmergency medical services (EMS) programs, which provide an alternative to traditional EMS dispatch or transport to the emergency department (ED), are becoming widely implemented. This scoping review identified and catalogued all outcomes used to measure such alternative EMS programs.Data SourceBroad systematized bibliographic and grey literature searches were conducted.Study SelectionInclusion criteria were 911 callers/EMS patients, reported on alternatives to traditional EMS dispatch OR traditional EMS transport to the ED, and reported an outcome measure.Data ExtractionThe reports were categorized as either alternative to dispatch or to EMS transport, and outcome measures were categorized and described.Data SynthesisThe bibliographic search retrieved 13,215 records, of which 34 articles met the inclusion criteria, with an additional 10 added from reference list hand-searching (n=44 included). In the grey literature search, 31 websites were identified, from which four met criteria and were retrieved (n=4 included). Fifteen reports (16 studies) described alternatives to EMS dispatch, and 33 reports described alternatives to EMS transport. The most common outcomes reported in the alternatives to EMS dispatch reports were service utilization and decision accuracy. Twenty-four different specific outcomes were reported. The most common outcomes reported in the alternatives to EMS transport reports were service utilization and safety, and 50 different specific outcomes were reported.ConclusionsNumerous outcome measures were identified in reports of alternative EMS programs, which were catalogued and described. Researchers and program leaders should achieve consensus on uniform outcome measures, to allow benchmarking and improve comparison across programs.

Abstract
We evaluated the quality of telephone triage and the appropriateness of the decisions resulting from it at a primary care out-of-hours service. Four simulated clinical cases were used in the Incognito Standardized Patient method: an adult with nosebleed, an adult with fever, a child with fever and a child with vomiting. There was a set of obligatory questions for each case, translated from those used in a previous study. Quality was assessed by the proportion of questions asked by the call-handlers during telephone triage versus those that should have been asked. A total of 22 out-of-hours doctors were involved in the study, working in two different locations in the Verona city area. Over a 4-month period each of the four simulated clinical cases was used five times in calls to the two centres involved. The proportion of obligatory questions asked compared to those expected to be asked was 27-36%. On three occasions out of the 40 simulations, all of which were considered to be manageable by telephone, the patient was advised to go to an outpatient clinic for a face-to-face evaluation. The average duration of the calls was 3 min 47 s. The quality of telephone triage in the regions studied was low and provided considerable room for improvement. This is relevant to patient safety and risk management of the service.

Abstract
OBJECTIVE Secondary telephone triage to divert low-acuity patients to alternative non-ambulance services before ambulance arrival has been trialled in the UK and USA as a management strategy to cope with the increase in ambulance demand. The objective of this systematic review was to examine the literature on the structure, safety and success of secondary triage systems. METHODS For inclusion in the study, the telephone triage system had to be a secondary process, receiving referred patients who had already been categorised as low priority by a primary triage process. Two independent reviewers conducted the search to identify relevant studies. Six articles and one report were identified. RESULTS The major theme of the papers was the safety and accuracy of secondary telephone triage in identifying low-acuity patients. Two studies also discussed patient satisfaction. There was a low incidence of adverse events, as expected as these patients had already been subjected to primary telephone triage. In the studies identifying ambulance dispatch as a potential final disposition, at least half of the patients were diverted away from ambulance dispatch. In the studies that identified self/home care as a final disposition, a maximum of 31% of patients were categorised to this outcome. Otherwise all patients were recommended for assessment by a healthcare professional other than ambulance clinicians. Patients appeared to be satisfied with secondary telephone triage on follow-up. CONCLUSIONS These results suggest that, while secondary triage of these patients is safe, further research is required to determine its most appropriate structure and its effect on ambulance demand.

Abstract
INTRODUCTION Although EMS agencies have been designed to efficiently provide medical assistance to individuals, the overuse of 9-1-1 as an alternative to primary medical care has resulted in the need for new methods to respond to this increasing demand. Our study analyzes the efficacy of classifying specific low-acuity calls that can be transferred to an advice-line nurse for further medical instruction. The objectives of our study were to analyze the impact of implementing this protocol and resultant patient feedback regarding the transfer to an advice-line nurse. METHODS We collected data for retrospective review from April 2011 to April 2012 from a single municipal EMS agency with an average annual call volume of approximately 90,000. Medical Priority Dispatch System response codes were assigned to calls based on patient acuity. Patients classified under Omega response codes were assessed for eligibility of transfer to nurse advice lines. Exclusion criteria included the following: if the call was placed by a third-party caller; if the patient refused to be transferred to the advice-line nurse; anytime the MPDS system was not used; if the patient was referred from a skilled nursing facility, school, or university nursing office, or physician's office. Telephone surveys were conducted for those patients who spoke to an advice-line nurse and did not receive an ambulance response 24 hours after calling 9-1-1 to obtain patient feedback. RESULTS The database included 1660 patients initially classified as Omega and eligible for transfer to an advice-line nurse. After applying the exclusion criteria, 329 (19.8%) patients were ultimately transferred to an advice-line nurse and 204 (12.3%) received no ambulance response. Of those patients who were not transported by ambulance 118 (57.8%), patients completed telephone follow-up, with 104 (88.1%) reporting the nontransport option met their health-care needs and 108 (91.5%) responding they would accept the transfer again for a similar complaint. CONCLUSION We identified an average of two patients per day as eligible for transfer to the nurse advice line, with less than one patient successfully completing the Omega protocol per day. While impact was limited, there was a decrease in ambulance response.

Abstract
Background. Achieving knowledge translation in healthcare is growing in importance but methods to capture impact of research are not well developed. We present an attempt to capture impact of a programme of research in prehospital emergency care, aiming to inform the development of EMS models of care that avoid, when appropriate, conveyance of patients to hospital for immediate care. Methods. We describe the programme and its dissemination, present examples of its influence on policy and practice, internationally, and analyse routine UK statistics to determine whether conveyance practice has changed. Results. The programme comprises eight research studies, to a value of >£4 m. Findings have been disseminated through 18 published papers, cited 274 times in academic journals. We describe examples of how evidence has been put into practice, including new models of care in Canada and Australia. Routine statistics in England show that, alongside rising demand, conveyance rates have fallen from 90% to 58% over a 12-year period, 2,721 million fewer journeys, with publication of key studies 2003–2008. Comment. We have set out the rationale, key features, and impact on practice of a programme of publicly funded research. We describe evidence of knowledge translation, whilst recognising limitations in methods for capturing impact.

Abstract
AIM To review the evidence regarding non-transported older people who have fallen in relation to non-transportation rates, outcomes and impact of alternate care pathways. METHOD Electronic databases and reference lists of included studies (up to December 2011) were systematically searched. Studies were eligible if they included data on non-transportation rates, information on outcomes or alternate care pathways for older people who have fallen. RESULTS Twelve studies were included. Non-transportation rates following a fall ranged from 11% to 56%. Up to 49% of non-transported people who have fallen had unplanned health-care contact within 28 days of the initial incident. Attendance by specially trained paramedics and individualised multifactorial interventions significantly reduced adverse events including subsequent falls, emergency ambulance calls, emergency department attendance and hospital admission. CONCLUSION Limited but promising evidence shows that appropriate interventions can improve health outcomes of non-transported older people who have fallen. Further studies are needed to explore alternate care pathways and promote more efficient use of health services.

Abstract
BACKGROUND Telephone calls for emergency ambulances are rising annually, increasing the pressure on ambulance resources for clinical problems that could often be appropriately managed in primary care. OBJECTIVE To explore and understand patient and carer decision making around calling an ambulance for primary care-appropriate health problems. METHODS Semistructured interviews were conducted with patients and carers who had called an ambulance for a primary care-appropriate problem. Participants were identified using a purposive sampling method by a non-participating research clinician attending '999' ambulance calls. A thematic analysis of interview transcripts was undertaken. RESULTS A superordinate theme, patient and carer anxiety in urgent-care decision making, and four subthemes were explored: perceptions of ambulance-based urgent care; contrasting perceptions of community-based urgent care; influence of previous urgent care experiences in decision making; and interpersonal factors in lay assessment and management of medical risk and subsequent decision making. CONCLUSIONS Many calls are based on fundamental misconceptions about the types of treatment other urgent-care avenues can provide, which may be amenable to educational intervention. This is particularly relevant for patients with chronic conditions with frequent exacerbations. Callers who have care responsibilities often default to the most immediate response available, with decision making driven by a lower tolerance of perceived risk. There may be a greater role for more detailed triage in these cases, and closer working between ambulance responses and urgent primary care, as a perceived or actual distance between these two service sectors may be influencing patient decision making on urgent care.

Abstract
AbstractIntroduction:Over-triage of patients by emergency medical services (EMS) dispatch is thought to be an acceptable alternative to under-triage, which may delay how quickly life-saving care reaches a patient. Previous studies have looked at advanced life support (ALS) misutilization in urban- and county-based EMS systems and have attempted to analyze how dispatch methods either contribute to or alleviate this problem.1–5Objective:The purpose of this study is to assess the relationship between dispatches of a cardiac nature in a Medical Priority Dispatch (MPD) system, and the actual clinical diagnosis as determined by an emergency department physician.Methods:Calls for emergency medical assistance in a suburban community outside of a major metropolitan area were surveyed over a three-month period. Medical Priority Dispatch protocols determined that 104 of these calls were cardiac-related. Of these emergency calls, 56 (53.8%) patients were transported to the local community hospital and treated by the emergency physician. A retrospective review of the medical records was conducted to determine whether the patient had a cardiac-related discharge diagnosis from the emergency department.Results:Sixteen (28.6%) of the patients in this cohort were diagnosed with a cardiac-related condition upon discharge from the emergency department. Forty (71.4%) were diagnosed with a non-cardiac-related condition. The positive, predictive value of the dispatch protocol for the detection of an actual cardiac emergency in this EMS system was 28.6%.Conclusion:In this suburban community, the MPD system may over-triage emergency medical responses to cardiac emergencies. This can result in the only ALS (paramedic) unit in the community being unavailable in certain situations. Future studies should be conducted to determine what level (in any) of over-triage is appropriate in EMS systems using a MPD system.

Abstract
With increasing demands for emergency medical services (EMS), many EMS jurisdictions are utilizing EMS provider-initiated nontransport policies as a method to offload potentially nonemergent patients from the EMS system. EMS provider determination of medical necessity, resulting in nontransport of patients, has the potential to avert unnecessary emergency department visits. However, EMS systems that utilize these policies must have additional education for the providers, a quality improvement process, and active physician oversight. In addition, EMS provider determination of nontransport for a specific situation should be supported by evidence in the peer-reviewed literature that the practice is safe. Further, EMS systems that do not utilize these programs should not be financially penalized. Payment for EMS services should be based on the prudent layperson standard. EMS systems that do utilize nontransport policies should be appropriately reimbursed, as this represents potential cost savings to the health care system.

Abstract
BACKGROUND Due to emergency care overcrowding, right care at the right place and time is necessary. Uniform triage of patients contacting different emergency care settings will improve quality of care and communication between health care providers. OBJECTIVE Validation of the computer-based Netherlands Triage System (NTS) developed for physical triage at emergency departments (EDs) and telephone triage at general practitioner cooperatives (GPCs). METHODS Prospective observational study with patients attending the ED of a university-affiliated hospital (September 2008 to November 2008) or contacting an urban GPC (December 2008 to February 2009). For validation of the NTS, we defined surrogate urgency markers as best proxies for true urgency. For physical triage (ED): resource use, hospitalization and follow-up. For telephone triage (GPC): referral to ED, self-care advice after telephone consultation or GP advice after physical consultation. Associations between NTS urgency levels and surrogate urgency markers were evaluated using chi-square tests for trend. RESULTS We included nearly 10 000 patients. For physical triage at ED, NTS urgency levels were associated with resource use, hospitalization and follow-up. For telephone triage at GPC, trends towards more ED referrals in high NTS urgency levels and more self-care advices after telephone consultation in lower NTS urgency levels were found. The association between NTS urgency classification and GP advice was less explicit. Similar results were found for children; however, we found no association between NTS urgency level and GP advice. CONCLUSIONS Physically and telephone-assigned NTS urgency levels were associated with majority of surrogate urgency markers. The NTS as single triage system for physical and telephone triage seems feasible.

Abstract
In this paper we provide an overview of the way that information and communication technologies have been used for emergency healthcare support. The paper provides a literature review of case studies exploring information systems for monitoring signals, images, medical videos, as well as information protocols used during emergency health care support, and describes future trends. We anticipate that eEmergency systems can significantly improve the delivery of healthcare during emergency cases. However, the monitoring and evaluation of these systems and especially their use in daily practice still remains a goal to be achieved.

Abstract
INTRODUCTION Reducing unnecessary ambulance transports may have operational and economic benefits for emergency medical services (EMS) agencies and receiving emergency departments. However, no consensus exists on the ability of paramedics to accurately and safely identify patients who do not require ambulance transport. Objective. This systematic review and meta-analysis evaluated studies reporting U.S. paramedics' ability to determine medical necessity of ambulance transport. METHODS PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Cochrane Library databases were searched using Cochrane Prehospital and Emergency Care Field search terms combined with the Medical Subject Headings (MeSH) terms "triage"; "utilization review"; "health services misuse"; "severity of illness index," and "trauma severity indices." Two reviewers independently evaluated each title to identify relevant studies; each abstract then underwent independent review to identify studies requiring full appraisal. Inclusion criteria were original research; emergency responses; determinations of medical necessity by U.S. paramedics; and a reference standard comparison. The primary outcome measure of interest was the negative predictive value (NPV) of paramedic determinations. For studies reporting sufficient data, agreement between paramedic and reference standard determinations was measured using kappa; sensitivity, specificity, and positive predictive value (PPV) were also calculated. RESULTS From 9,752 identified titles, 214 abstracts were evaluated, with 61 studies selected for full review. Five studies met the inclusion criteria (interrater reliability, kappa = 0.75). Reference standards included physician opinion (n = 3), hospital admission (n = 1), and a composite of physician opinion and patient clinical circumstances (n = 1). The NPV ranged from 0.610 to 0.997. Results lacked homogeneity across studies; meta-analysis using a random-effects model produced an aggregate NPV of 0.912 (95% confidence interval: 0.707-0.978). Only two studies reported complete 2 x 2 data: kappa was 0.105 and 0.427; sensitivity was 0.992 and 0.841; specificity was 0.356 and 0.581; and PPV was 0.158 and 0.823. CONCLUSION The results of the few studies evaluating U.S. paramedic determinations of medical necessity for ambulance transport vary considerably, and only two studies report complete data. The aggregate NPV of the paramedic determinations is 0.91, with a lower confidence limit of 0.71. These data do not support the practice of paramedics' determining whether patients require ambulance transport. These findings have implications for EMS systems, emergency departments, and third-party payers.

Abstract
BACKGROUND The first link in the 'chain of survival' is the activation of Emergency Medical Services (EMS). In the major part of Denmark, police officers operate the alarm 1-1-2 centre, including calls for EMS. Our aim was to study the police 1-1-2 operators' accuracy in identifying calls concerning patients with loss of consciousness as a key symptom of life-threatening conditions. 'Unconsciousness' was defined as patients with a Glasgow Coma Scale (GCS) score of < 9, scored by the on-scene anaesthesiologist from the Mobile Emergency Care Unit (MECU). METHODS This study was an observational cohort study based on data from the Police 1-1-2 Database and the Aarhus County Pre-hospital Database containing data from MECU cases during 6 months in 2004-05. RESULTS Two thousand, three hundred and forty-three emergency calls with MECU dispatch were identified. In 1655 cases, both 1-1-2 data and the GCS score were recorded. Two hundred and ninety-five patients were found with a GCS score of < 9 at MECU arrival, 243 of whom were reported 'unconscious' by 1-1-2, giving a sensitivity of 82%. One thousand, three hundred and sixty patients were found with a GCS score of > or = 9, 972 of whom were reported 'awake', giving a specificity of 72%. The positive predictive value (percentage of patients found with a GCS score of < 9 at MECU arrival amongst patients reported as 'unconscious') was 39%. CONCLUSIONS The accuracy was moderate with room for improvement. The positive predictive value was low, indicating over-triage of MECU.

Abstract
OBJECTIVES In Japan, the demand for pediatric emergency medicine has been increasing, especially in the evening. The purpose of this study was to identify the reasons for overcrowding of pediatric emergency facilities in the evening. METHODS A population-based survey was conducted in Yokohama City, Japan, that targeted parents of children 1 or 3 years of age. These children participate in regular health checkups. Questionnaires about their child's illnesses and the pediatric emergency system were mailed to 30,000 parents of a child expected to undergo a health checkup between May 2004 and January 2005. RESULTS Data obtained from the completed questionnaires indicated that many parents noticed their child's illness or injury most frequently during the evening, when most medical facilities are closed. The peak period when parents noticed their child's illness was the evening (4:00 pm-12 midnight, 54.4%), followed by the daytime (8:00 am-4:00 pm, 30.3%) and then the nighttime (12 midnight-8:00 am, 15.3%). During all 3 periods, parents felt it difficult to judge their child's condition and thus many used emergency facilities unnecessarily. CONCLUSIONS The overcrowding of pediatric emergency facilities in the evening is likely due mainly to a mismatch between the peak time of children's illnesses and the office hours of pediatric clinics. Parents' difficulties in assessing their child's condition and anxiety over their child's illness and injuries seem to be other factors that contribute to this imbalance.

Abstract
OBJECTIVES To evaluate whether a computer-based decision support system could be useful for the emergency medical system when identifying patients with acute myocardial infarction (AMI) or life-threatening conditions and thereby improve the allocation of life support level. METHODS Patients in the Municipality of Göteborg who dialled the dispatch centre due to chest pain during a period of 3 months. To analyse the relationship between patient characteristics (according to a case record form used during an interview) and the response variables (AMI or life-threatening condition), multivariate logistic regression was used. For each patient, the probability of AMI/life-threatening condition was estimated by the model. We used these probabilities retrospectively to allocate advanced life support or basic life support. This model allocation was then compared with the true allocation made by the dispatchers. RESULTS The sensitivity, that is, the percentage of AMI patients allocated to advanced life support, was 85.7% in relation to the true allocation made by the dispatchers. The corresponding sensitivity regarding allocation made by the model was 92.4% (P=0.17). The specificity was also slightly higher for the model allocation than the dispatcher allocation. Among the 15 patients with AMI who were allocated to basic life support by the dispatchers, nine died (eight during and one after hospitalization). Among the eight patients with AMI allocated to basic life support by the model, only one patient died (in hospital) (P=0.02). CONCLUSION A computer-based decision support system including a prevalence function could be a valuable tool for allocating the level of life support. The case record form, however, used for the interview can be refined and a model based on a larger sample and confirmed in a prospective study is recommended.

Abstract
Recognition of the paramedic "profession" began in 2003, with the introduction of statutory registration and the promotion of graduate entry. This paper explores the published evidence which surrounds paramedic practice in an attempt to identify the skills, training, and professional capacity which paramedics of the future will require. A systematic analysis was carried out of key reviews and commentaries published between January 1995 and April 2004, and informal discussions with experts and researchers in the field were undertaken. There remains little high quality published evidence with which to validate many aspects of current paramedic practice. To keep pace with service developments, paramedic training must embrace the complexities of autonomous practice. Undoubtedly in the short term, paramedics must be taught to appropriately identify and manage a far wider range of commonly occurring conditions, minor illnesses, and trauma. However, in the longer term, and more importantly, paramedics must learn to work together to take ownership of the basic philosophies of their practice, which must have their foundation in valid and reliable research.

Abstract
BACKGROUND In recent years there has been a growth in the use of the telephone consultation for healthcare problems. This has developed, in part, as a response to increased demand for GP and accident and emergency department care. AIM To assess the effects of telephone consultation and triage on safety, service use, and patient satisfaction. DESIGN OF STUDY We looked at randomised controlled trials, controlled studies, controlled before/after studies, and interrupted time series of telephone consultation or triage in a general healthcare setting. SETTING All healthcare settings were included but the majority of studies were in primary care. METHOD We searched the Cochrane Central Register of Controlled Trials, EPOC specialised register, PubMed, EMBASE, CINAHL, SIGLE, and the National Research Register and checked reference lists of identified studies and review articles. Two reviewers independently screened studies for inclusion, extracted data, and assessed study quality. RESULTS Nine studies met our inclusion criteria: five randomised controlled trials; one controlled trial; and three interrupted time series. Six studies compared telephone consultation with normal care; four by a doctor, one by a nurse, and one by a clinic clerk. Three of five studies found a significant decrease in visits to GPs but two found an increase in return consultations. In general at least 50% (range = 25.5-72.2%) of calls were handled by telephone consultation alone. Of seven studies reporting accident and emergency department visits, six showed no difference between the groups and one--of nurse telephone consultation--found an increase. Two studies reported deaths and found no difference between nurse telephone consultation and normal care. CONCLUSIONS Although telephone consultation appears to have the potential to reduce GP workload, questions remain about its effect on service use. Further rigorous evaluation is needed with emphasis on service use, safety, cost, and patient satisfaction.

Abstract
OBJECTIVES To examine the emerging role of the emergency care practitioner (ECP) with comparisons to paramedic practice. Key activities were identified of newly appointed ECPs using qualitative methodology and a qualitative and quantitative comparison of patient treatment was made. METHOD A constructivist methodology taking account of stakeholder input and drawing upon the constant comparisons of different group's construction of reality. Four practitioners completed reflective patient case studies and adapted patient report forms, which were compared with a second case group of 11 paramedics. In addition individual and focus groups interviews were performed with key stakeholders. RESULTS In the comparison between ECP and paramedic roles, 331 paramedic incidents were compared with 170 ECP reports. ECPs treated 28% of patients on scene compared with 18% by paramedics (p = 0.007). Fifty per cent of ECPs patients were conveyed compared with 64% of paramedics (p = 0.000). Analysis of the 269 reflective reports and 14 stakeholder interviews revealed four key themes. Firstly, ECPs had a beneficial impact on the deployment of resources, especially relating to non-conveyance. Secondly, their training and education improved their decision making repertoire and developed their confidence for a leadership role. Thirdly, inter-agency collaboration and cooperation was improved, and finally, care benefits were increased especially relating to immediacy of treatment and referral mechanisms. CONCLUSIONS The results indicate that an investment in the ECP role could be beneficial, however, more work is required to evaluate the development of practice, the quality of care, and cost benefits.

Abstract
OBJECTIVE To assess the safety of nurses and paramedics offering telephone assessment, triage, and advice as an alternative to immediate ambulance dispatch for emergency ambulance service callers classified by lay call takers as presenting with "non-serious" problems (category C calls). DESIGN Data for this study were collected as part of a pragmatic randomised controlled trial reported elsewhere. The intervention arm of the trial comprised nurse or paramedic telephone consultation using a computerised decision support system to assess, triage, and advise patients whose calls to the emergency ambulance service had been classified as "non-serious" by call takers applying standard priority dispatch criteria. A multidisciplinary expert clinical panel reviewed data from ambulance service, accident and emergency department, hospital inpatient and general practice records, and call transcripts for patients triaged by nurses and paramedics into categories that indicated that dispatch of an emergency ambulance was unnecessary. All cases for which one or more members of the panel rated that an emergency ambulance should have been dispatched were re-reviewed by the entire panel for an assessment of the "life risk" that might have resulted. SETTING Ambulance services in London and the West Midlands, UK. STUDY POPULATION Of 635 category C patients assessed by nurses and paramedics, 330 (52%) cases that had been triaged as not requiring an emergency ambulance were identified. MAIN OUTCOME MEASURES Assessment of safety of triage decisions. RESULTS Sufficient data were available from the routine clinical records of 239 (72%) subjects to allow review by the specialist panel. For 231 (96.7%) sets of case notes reviewed, the majority of the panel concurred with the nurses' or paramedics' triage decision. Following secondary review of the records of the remaining eight patients, only two were rated by the majority as having required an emergency ambulance within 14 minutes. For neither of these did a majority of the panel consider that the patient would have been at "life risk" without an emergency ambulance being immediately dispatched. However, the transcripts of these two calls indicated that the correct triage decision had been communicated to the patient, which suggests that the triage decision had been incorrectly entered into the decision support system. CONCLUSIONS Telephone advice may be a safe method of managing many category C callers to 999 ambulance services. A clinical trial of the full implementation of this intervention is needed, large enough to exclude the possibility of rare adverse events.

Abstract
BACKGROUND Telephone consultation is the process where calls are received, assessed and managed by giving advice or by referral to a more appropriate service. In recent years there has been a growth in telephone consultation developed, in part, as a response to increased demand for General Practitioner (GP) and Accident and Emergency (A&E) department care. OBJECTIVES To assess the effects of telephone consultation on safety, service usage and patient satisfaction and to compare telephone consultation by different health care professionals. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials, the specialised register of the Cochrane Effective Practice and Organisation of Care (EPOC) group, Pubmed, EMBASE, CINAHL, SIGLE, and the National Research Register. We checked reference lists of identified studies and review articles and contacted experts in the field. The search was not restricted by language or publication status. SELECTION CRITERIA Randomised controlled trials (RCTs), controlled studies, controlled before/after studies (CBAs) and interrupted time series (ITSs) of telephone consultation or triage in a general health care setting. Disease specific phone lines were excluded. DATA COLLECTION AND ANALYSIS Two reviewers independently screened studies for inclusion in the review, extracted data and assessed study quality. Data were collected on adverse events, service usage, cost and patient satisfaction. Due to heterogeneity we did not pool studies in a meta-analysis and instead present a narrative summary of the findings. MAIN RESULTS Nine studies met our inclusion criteria, five RCTs, one CCT and three ITSs. Six studies compared telephone consultation versus normal care; four by a doctor, one by a nurse and one by a clinic clerk. Three studies compared telephone consultation by different types of health care workers; two compared nurses with doctors and one compared health assistants with doctors or nurses. Three of five studies found a decrease in visits to GP's but two found a significant increase in return consultations. In general at least 50% of calls were handled by telephone advice alone. Seven studies looked at accident and emergency department visits, six showed no difference between the groups and one, of nurse telephone consultation, found an increase in visits. Two studies reported deaths and found no difference between nurse telephone triage and normal care. REVIEWERS' CONCLUSIONS Telephone consultation appears to reduce the number of surgery contacts and out-of-hours visits by general practitioners. However, questions remain about its affect on service use and further rigorous evaluation is needed with emphasis on service use, safety, cost and patient satisfaction.

Resuscitation 2004; 61:297-302. [PMID: 15172708 DOI: 10.1016/j.resuscitation.2004.01.008] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2003] [Accepted: 01/02/2004] [Indexed: 11/15/2022]
Abstract
OBJECTIVES This study was planned to record prehospital death rates in four medical priority categories (A, B, C and D) and to evaluate if deaths in lower urgency categories C and D (target response times 20 and 90 min) could have been avoided by a faster ambulance response. METHODS The design was a community based cohort study including an expert panel evaluation of the deaths. The study was conducted in the Emergency Medical Services in Helsinki, Finland. All consecutive ambulance calls excluding interhospital patient transfers between 1 January 1999 and 31 December 2002 were included. Prehospital mortality and avoidability of prehospital deaths by a faster ambulance response (maximum 8 min) were used as main outcome measures. RESULTS A total of 151928 calls were prioritized in the dispatching centre (category A 8677 calls, B 41005, C 71991 and D 30255). Prehospital death occurred 451 times in category A, 468 times in category B, 73 times in category C and 8 times in category D calls. Respectively, the prehospital death rates per 1000 calls were 52.0 (A), 11.4 (B), 1.0 (C) and 0.3 (D) (P < 0.0001). The expert panel judged that 1 (1.3%) of category C deaths would have been avoidable, 24 (32.9%) potentially avoidable and 48 (65.8%) not avoidable by a more rapid ambulance response. The corresponding figures for category D deaths were 0 (0%), 5 (62.5%) and 3 (37.5%), respectively. CONCLUSIONS The use of medical priority dispatching was associated with very low prehospital mortality in lower urgency categories C and D. Approximately, one-third of those deaths could probably be prevented by a faster ambulance response but the price would be a three-fold increase in calls with blue lights and siren. Further studies are needed to find out if our results are applicable to other types of EMS systems.
