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.

Clinician and Caregiver Determinations of Acuity for Children Transported by Emergency Medical Services: A Prospective Observational Study. Ann Emerg Med 2023; 81:343-352. [PMID: 36334958 PMCID: PMC9974545 DOI: 10.1016/j.annemergmed.2022.09.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 08/24/2022] [Accepted: 09/02/2022] [Indexed: 11/06/2022]
Abstract
STUDY OBJECTIVE Many Emergency Medical Services (EMS) agencies have developed alternative disposition processes for patients with nonemergency problems, but there is a lack of evidence demonstrating EMS clinicians can accurately determine acuity in pediatric patients. Our study objective was to determine EMS and other stakeholders' ability to identify low acuity pediatric EMS patients. METHODS We conducted a prospective, observational study of children transported to a pediatric emergency department (ED) by EMS. Acuity was defined using a composite measure that included data from the patient's vital signs and examination, resources used (laboratory results, radiographs, etc), and disposition. For each patient, an EMS clinician, patient caregiver, ED nurse, and ED provider completed a survey as soon as possible after the patient's arrival at the ED. The survey asked respondents 2 questions: to state their level of agreement that a patient was low acuity and could the patient have been managed by various alternative dispositions. For each respondent group, we calculated the sensitivity, specificity, and positive and negative predictive values for low acuity versus the composite measure. RESULTS From August 2020 through September 2021, we approached 1,015 caregivers, of whom 996 (99.8%) agreed to participate and completed the survey. Survey completion varied between 78.7% and 84.1% for EMS and ED nurses and providers. The mean patient age was 7 years, 62.6% were non-Hispanic Black, and 60% were enrolled in public insurance programs. Of the 996 patient encounters, 33% were determined to be low acuity by the composite measure. The positive predictive value for EMS clinicians when identifying low acuity children was 0.60 (95% confidence intervals [CI], 0.58 to 0.67). The positive predictive value for ED nurses and providers was 0.67 (95% CI, 0.61 to 0.72) and 0.68 (95% CI, 0.63 to 0.74) respectively. The negative predictive value for EMS clinicians when identifying not low acuity children was 0.62 (95% CI, 0.58 to 0.67). The negative predictive value for ED nurses and providers was 0.72 (95% CI, 0.68 to 0.76) and 0.73 (95% CI, 0.70 to 0.77) respectively. Caregivers had the lowest positive predictive value 0.34 (95% CI, 0.30 to 0.40) but the highest negative predictive value 0.82 (95% CI, 0.79 to 0.85). The EMS clinicians, ED nurses and providers were more likely than caregivers to think that a child with a low acuity complaint could have been safely managed by alternative disposition. CONCLUSION All 4 groups studied had a limited ability to identify which children transported by EMS would have no emergency resource needs, and support for alternative disposition was limited. For children to be included in alternative disposition processes, novel triage tools, training, and oversight will be required to prevent undertriage.

Abstract
Ambulance services worldwide have transformed over time into health care services that not only attend to life-threatening emergencies, but are also increasingly being utilised for patients with low-acuity or non-urgent illness and injury. As a result, there has been a need to adapt and include mechanisms to assist paramedics in the assessment and management of such patients, including alternative pathways of care. However, it has been identified that education and training for paramedics in the care of low-acuity patients is limited. This study aims to identify potential gaps in the literature and inform further research, paramedic education and training, patient care guidelines, and policy. A scoping review will be conducted utilising the Joanna Briggs Institutes methodology. A range of relevant electronic databases will be searched along with the grey literature, using search terms related to paramedic education for low-acuity patient care pathways. The search results will be screened by two authors and presented in the PRISMA-ScR format, with articles presented in tabular format and analysed thematically. The results of this scoping review will inform further research exploring paramedic education, clinical guidelines, policy and experiences in the management of low-acuity patients.

"Older People Want to Be in Their Own Homes": A Service Evaluation of Patient and Carer Feedback after Pathfinder Responded to Their Emergency Calls. PREHOSP EMERG CARE 2023; 27:866-874. [PMID: 36633524 DOI: 10.1080/10903127.2023.2168094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 01/09/2023] [Accepted: 01/10/2023] [Indexed: 01/13/2023]
Abstract
OBJECTIVE Older people experience high rates of adverse outcomes following emergency department (ED) presentation. There is growing evidence to support alternative care pathways for certain types of emergency medical services (EMS) calls. Pathfinder is one such service and targets patients aged 65 years and over, whose presenting issues can be safely managed at home by immediate paramedic, occupational therapy, and/or physiotherapy interventions. The aim of this service evaluation was to understand how older people feel about being treated at home as a result of EMS calls and to understand their experiences of the Pathfinder service. METHODS This was a thematic analysis of open-ended responses recorded from telephone interviews during routine service evaluation with service users (patients or their next-of-kin). RESULTS Of 573 service users, telephone interviews were conducted with 429 (75%). Five primary themes were identified: (1) professionalism of the multidisciplinary clinical team; (2) "the right service, in the right place, at the right time"; (3) role of Pathfinder in "getting the ball rolling"; (4) lasting effects of the experience on the patient and his or her next-of-kin; (5) value of skilled communication with the older person. CONCLUSION Older people and their next-of-kin voiced a clear preference for hospital avoidance, and strongly valued the opportunity to be treated in their homes at the time of an EMS call rather than default conveyance to the ED. They appreciated the importance of a skilled multidisciplinary team with a follow-up service that effectively positions itself between the acute hospital and community services.

Emergency services utilization in Jakarta (Indonesia): a cross-sectional study of patients attending hospital emergency departments. BMC Health Serv Res 2022; 22:639. [PMID: 35562823 PMCID: PMC9103083 DOI: 10.1186/s12913-022-08061-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Accepted: 04/27/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Pre-hospital and emergency services in Indonesia are still developing. Despite recent improvements in the Indonesian healthcare system, issues with the provision of pre-hospital and emergency services persist. The demand for pre-hospital and emergency services has not been the subject of previous research and, therefore, has not been fully understood. Our research explored the utilization of emergency medical services by patients attending hospital emergency departments in Jakarta, Indonesia. METHODS The study used a cross-sectional survey design involving five general hospitals (four government-funded and one private). Each patient's demographic profile, medical conditions, time to treatment, and mode of transport to reach the hospital were analysed using descriptive statistics. RESULTS A total of 1964 (62%) patients were surveyed. The median age of patients was 44 years with an interquartile range (IQR) of 26 to 58 years. Life-threatening conditions such as trauma and cardiovascular disease were found in 8.6 and 6.6% of patients, respectively. The majority of patients with trauma travelled to the hospital using a motorcycle or car (59.8%). An ambulance was used by only 9.3% of all patients and 38% of patients reported that they were not aware of the availability of ambulances. Ambulance response time was longer as compared to other modes of transportation (median: 24 minutes and IQR: 12 to 54 minutes). The longest time to treatment was experienced by patients with neurological disease, with a median time of 120 minutes (IQR: 78 to 270 minutes). Patients who used ambulances incurred higher costs as compared to those patients who did not use ambulances. CONCLUSION The low utilization of emergency ambulances in Jakarta could be contributed to patients' lack of awareness of medical symptoms and the existence of ambulance services, and patients' disinclination to use ambulances due to high costs and long response times. The emergency ambulance services can be improved by increasing population awareness on symptoms that warrant the use of ambulances and reducing the cost burden related to ambulance use.

Abstract
Background Ambulance patients are usually transported to the hospital in the emergency medical service (EMS) system. The aim of this study was to describe the non‐conveyance practice in the Helsinki EMS system and to report mortality following non‐conveyance decisions. Methods All prehospital patients ≥16 years attended by the EMS but not transported to a hospital during 2013–2017 were included in the study. EMS mission‐ and patient‐related factors were collected and examined in relation to patient death within 30 days of the EMS non‐conveyance decision. Results The EMS performed 324,207 missions with a patient during the study period. The patient was not transported in 95,909 (29.6%) missions; 72,233 missions met the study criteria. The patient mean age (standard deviation) was 59.5 (22.5) years; 55.5% of patients were female. The most common dispatch codes were malaise (15.0%), suspected decline in vital signs (14.0%), and falling over (12.9%). A total of 960 (1.3%) patients died within 30 days after the non‐conveyance decision. Multivariate logistic regression analysis revealed that mortality was associated with the patient's inability to walk (odds ratio 3.19, 95% confidence interval 2.67–3.80), ambulance dispatch due to shortness of breath (2.73, 2.27–3.27), decreased level of consciousness (2.72, 1.75–4.10), decreased blood oxygen saturation (2.64, 2.27–3.06), and abnormal systolic blood pressure (2.48, 1.79–3.37). Conclusion One‐third of EMS missions did not result in patient transport to the hospital. Thirty‐day mortality was 1.3%. Abnormalities in multiple respiratory‐related vital signs were associated with an increased likelihood of death within 30 days.

Abstract
BACKGROUND many patients brought to emergency departments (EDs) following an emergency medical services (EMS) call have non-urgent needs that could be treated elsewhere. Older people are particularly vulnerable to adverse events while attending the ED. Alternative care pathway models can reduce ED crowding and improve outcomes. Internationally, there is no consensus on which model is recommended. AIM the aim of this study is to investigate the impact of the Pathfinder model on ED conveyance rates and patient safety. METHODS the Pathfinder service is a collaboration between the National Ambulance Service and Beaumont Hospital Occupational Therapy and Physiotherapy Departments. It is supported by the Government of Ireland's Sláintecare Integration fund. This is a retrospective cohort study of the Pathfinder service over a 5-month period. RESULTS one-hundred and seventy-eight patients were responded to by the Pathfinder 'Rapid Response Team'. Average age was 79.6 years (standard deviation 7.6), median clinical frailty score was 6 (interquartile range: 5-6). Sixty-four percent remained at home following initial review. None re-presented to the ED within 24 hours, and 10% re-presented within 7 days. The majority (67%) of patients required follow-up by the Pathfinder 'Follow-Up Team' and/or another community-based service. Feedback demonstrates 99% patient satisfaction with the service. CONCLUSION the Pathfinder service is a safe alternative to ED conveyance for older people following an EMS call. It is the first model of this kind to be evaluated in Ireland. The overwhelmingly positive feedback confirms that older people want this service. This model could expand, with local adaptation, nationally and internationally.

Abstract
BACKGROUND Trends in the characteristics and disease severity of patients using an after-hours house call (AHHC) medical service changed during the coronavirus disease (COVID-19) pandemic. However, there have been no reports on this issue since the start of the COVID-19 pandemic. This study aimed to investigate patients' tendencies to utilize an AHHC medical service for fever or common cold symptoms during the COVID-19 pandemic. METHODS This retrospective cohort study compared the characteristics and disease severity of patients with fever or common cold symptoms utilizing an AHHC medical service offered by a single large company between the control period (December 1, 2018 to April 30, 2019) and the COVID-19 pandemic exposure period (December 1, 2019 to April 30, 2020). We also assessed the proportion of these patients in relation to all patients calling the service for any reason. RESULTS During the control and COVID-19 pandemic exposure periods, a total of 6462 and 10,003 patients consulted the AHHC medical service, respectively. Of these, 5335 (82.6%) and 7423 (74.2%) patients had fever and common cold symptoms, respectively, during the control and COVID-19 pandemic exposure periods (P < 0.001). The corresponding median (interquartile range) ages were 8 (3-11) and 10 (4-33) years, respectively. The distribution of disease severity differed between the groups. The proportions of patients with mild, moderate, and severe illness were 71.1, 28.7, and 0.2% in the control period and 42.3, 56.7, and 0.9% in the COVID-19 pandemic exposure period, respectively (P < 0.001). CONCLUSIONS During the COVID-19 pandemic, the proportion of patients with fever or common cold symptoms was lower than that in the control period, but disease severity was significantly higher.

Experience of using video support by prehospital emergency care physician in ambulance care - an interview study with prehospital emergency nurses in Sweden. BMC Emerg Med 2021; 21:44. [PMID: 33827436 PMCID: PMC8028766 DOI: 10.1186/s12873-021-00435-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Accepted: 03/12/2021] [Indexed: 12/04/2022] Open
Abstract
Introduction When in need of emergency care and ambulance services, the ambulance nurse is often the first point of contact for the patient with healthcare. This role requires comprehensive knowledge of the ambulance nurse to be able to assign the right level of care and, if necessary, to provide self-care advice for patients with no further conveyance to hospital. Recently, an application was developed for transmitting real-time video to facilitate consultation between ambulance nurses and prehospital physicians in the role of regional medical support (RMS) for ambulance care. The use of video communication as a complement of medical support when referring to self-care is still an unexplored method in a prehospital setting. Our study aimed to elucidate ambulance nurses’ experience of video consultation with RMS physician during the assessment of patients considered to be triaged to self-care. Method We conducted a qualitative design study using semi-structured interviews with open questions. Twelve ambulance nurses were included in the study. To explore the ambulance nurses’ experience of performing video consultation with RMS physician, in cases when a patient was assessed and triaged to self-care, a content analysis was performed. Results A main category emerged from the results: “ Video consultation as decision support in the ambulance care promotes increased patient participation and for the ambulance nurses, it creates a feeling of increased patient safety “. The main category was based and formed on the following categories: “ Simultaneous presence of ambulance nurse and a physician increases patient participation during the assessment resulting in a confident care decision “. “Interprofessional collaboration strengthens the medical assessment”. “Video technology promotes accessibility for patients needs in the ambulance care regardless of emergency level”. Conclusions Ambulance nurses experienced that the use of video consultation increases patient involvement and confidence in healthcare when both the ambulance nurse and the physician were present when deciding on self-care advice. The live imaging allowed the ambulance nurse and prehospital physician to reach a consensus on the patient’s current medical care needs, which in turn led to a feeling of increased patient safety for the ambulance nurses.

Alternatives to direct emergency department conveyance of ambulance patients: a scoping review of the evidence. Scand J Trauma Resusc Emerg Med 2021; 29:4. [PMID: 33407771 PMCID: PMC7789540 DOI: 10.1186/s13049-020-00821-x] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 12/02/2020] [Indexed: 12/02/2022] Open
Abstract
Background The role of ambulance services is shifting, due in part to more intermediate, non-urgent patients who do not require direct emergency department conveyance, yet who cannot be safely left at home alone. Evidence surrounding the safety, effectiveness and efficiency of alternate care routes is not well known. Methods This scoping review sought to identify all studies that examined alternate routes of care for the non-urgent “intermediate” patient, as triaged on scene. Search terms for the sample (ambulances, paramedics, etc.) and intervention (e.g. referrals, alternate care route, non-conveyance) were combined. Articles were systematically searched using four databases and grey literature sources (February 2020). Independent researchers screened title-abstract and full text stages. Results Of 16,037 records, 41 examined alternate routes of care after triage by the on-scene paramedic. Eighteen articles considered quantitative patient data, 12 studies provided qualitative perspectives while 11 were consensus or opinion-based articles. The benefits of alternative schemes are well-recognised by patients, paramedics and stakeholders and there is supporting evidence for a positive impact on patient-centered care and operational efficiency. Challenges to successful use of schemes included: patient safety resulting from incorrect triage decisions, inadequate training, lack of formal partnerships between ambulance and supporting services, and insufficient evidence to support safe implementation or continued use. Studies often inaccurately defined success using proxies for patient safety (e.g. decision comparisons, rates of secondary contact). Finally, patients expressed willingness for such schemes but their preference must be better understood. Conclusions This broad summary offers initial support for alternate routes of care for intermediate, non-urgent patients. Even so, most studies lacked methodologically rigorous evidence and failed to evaluate safe patient outcomes. Some remedies appear to be available such as formal triage pathways, targeted training and organisational support, however there is an urgent need for more research and dissemination in this area.

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.

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.

The Korean Triage and Acuity Scale: associations with admission, disposition, mortality and length of stay in the emergency department. Int J Qual Health Care 2020; 31:449-455. [PMID: 30165654 DOI: 10.1093/intqhc/mzy184] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2018] [Revised: 06/20/2018] [Accepted: 08/12/2018] [Indexed: 11/12/2022] Open
Abstract
OBJECTIVE The Korean Triage and Acuity Scale (KTAS) was implemented in our emergency department (ED) in May 2016 and is fully integrated into the electronic medical record (EMR) system. Our objective was to determine whether the KTAS is associated with changes in admissions to the hospital, admission disposition, inpatient mortality and length of stay (LOS). DESIGN Quasi-experimental, uncontrolled before-and-after study. SETTING The urban tertiary teaching hospital with 1100 beds and receives approximately annual 90 000 ED visits. PARTICIPANTS 122 370 patients who visited the ED during the before-and-the after period. INTERVENTIONS ED staff were educated on the KTAS for 1 month, after which the KTAS evaluation period began. Admission, disposition, mortality and LOS were compared between the 'before' period (1 June 2015 to 30 April 2016) and the 'after' period (1 June 2016 to 30 April 2017). MAIN OUTCOME MEASURES Admissions to the hospital, admission disposition, inpatient mortality and LOS. RESULTS A total of 59 220 and 63 150 patients were included in the before-and-after periods of KTAS implementation, respectively. The pattern of admission and disposition changed significantly after implementation of the KTAS. The mean LOS was 343 min (standard deviation [SD] = 432 min) during the before period, which significantly decreased to 289 min (SD = 333 min) after implementation (P < 0.001). The total mortality rate was significantly reduced after implementation of the KTAS (213 (0.36%) vs. 179 (0.28%), P = 0.020). CONCLUSION Implementation of the KTAS changed admission and disposition patterns and reduced the LOS and mortality in the ED.

Patient characteristics, triage utilisation, level of care, and outcomes in an unselected adult patient population seen by the emergency medical services: a prospective observational study.

Abstract
Background Crowding in the emergency department (ED) is a safety concern, and pathways to bypass the ED have been introduced to reduce the time to definitive care. Conversely, a number of low-acuity patients in the ED could be assessed by the emergency medical services (EMS) as requiring a lower level of care. The limited access to primary care in Sweden leaves the EMS nurse to either assess the patient as requiring the ED or to stay at the scene. This study aimed to assess patient characteristics and evaluate the initial assessment by and utilisation of the ambulance triage system and the appropriateness of non-transport decisions. Methods A prospective observational study including 6712 patients aged ≥16 years was conducted. The patient records with 72 h of follow-up for non-transported patients were reviewed. Outcomes of death, time-critical conditions, complications within 48 h and final hospital assessment were evaluated. The Mann-Whitney U test, Fisher’s exact test, and Spearman’s rank correlation were used for statistical analysis. Results The median patient age was 66 years, and the most common medical history was a circulatory diagnosis. Males received a higher priority from dispatchers and were more frequently assessed at the scene as requiring hospital care. A total of 1312 patients (19.7%) were non-transported; a history of psychiatric disorders or no medical history was more commonly noted among these patients. Twelve (0.9%) of the 1312 patients not transported were later admitted with time-critical conditions. Full triage was applied in 77.4% of the cases, and older patients were triaged at the scene as an ‘unspecific condition’ more frequently than younger patients. Overall, the 30-day mortality was 4.1% (n = 274). Conclusions Age, sex, medical history, and presentation all appear to influence the initial assessment. A number of patients transported to ED could be managed at a lower level of care. A small proportion of the non-transported patients were later diagnosed with a time-critical condition, warranting improved assessment tools at the scene and education of the personnel focusing on the elderly population. These results may be useful in addressing resource allocation issues aiming at increasing patient safety.

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
OBJECTIVES To combat overcrowding in emergency departments, ambulance clinicians (ACs) are being encouraged to make on-site assessments regarding patients' need for conveyance to hospital, and this is creating new and challenging demands for ACs. This study aimed to describe ACs' experiences of assessing non-conveyed patients. DESIGN A phenomenological interview study based on a reflective lifeworld research approach. SETTING The target area for the study was Stockholm, Sweden, which has a population of approximately 2.3 million inhabitants. In this area, 73 ambulances perform approximately just over 200 000 ambulance assignments annually, and approximately 25 000 patients are non-conveyed each year. INFORMANTS 11 ACs. METHODS In-depth open-ended interviews. RESULTS ACs experience uncertainty regarding the accuracy of their assessments of non-conveyed patients. In particular, they fear conducting erroneous assessments that could harm patients. Avoiding hasty decisions is important for conducting safe patient assessments. Several challenging paradoxes were identified that complicate the non-conveyance situation, namely; responsibility, education and feedback paradoxes. The core of the responsibility paradox is that the increased responsibility associated with non-conveyance assessments is not accompanied with appropriate organisational support. Thus, frustration is experienced. The education paradox involves limited and inadequate non-conveyance education. This, in combination with limited support from non-conveyance guidelines, causes the clinical reality to be perceived as challenging and problematic. Finally, the feedback paradox relates to the obstruction of professional development as a result of an absence of learning possibilities after assessments. Additionally, ACs also described loneliness during non-conveyance situations. CONCLUSIONS This study suggests that, for ACs, performing non-conveyance assessments means experiencing a paradoxical professional existence. Despite these aggravating paradoxes, however, complex non-conveyance assessments continue to be performed and accompanied with limited organisational support. To create more favourable circumstances and, hopefully, safer assessments, further studies that focus on these paradoxes and non-conveyance are needed.

Abstract
Widespread use of Emergency Medicine Services (EMS) for non-emergency care has increased recently, causing overcrowding of the Emergency Department (ED). The increased availability of urgent care centers (UCCs), with their ability to see large numbers of unscheduled patients with more acute presentations, may offer a viable option for many EMS systems to divert non-emergent cases. Using a survey-based study combined with retrospective chart review, EMS provider ability to determine patient suitability for diversion to UCCs was assessed. Results indicated a rate of inappropriate diversion of 11.6%. UCCs may be an alternative option for EMS transport, however strict protocols with medical direction are needed.

Abstract
Objectives: Emergency ambulance services do not transport all patients to hospital. International literature reports non-transport rates ranging from 3.7-93.7%. In 2017, 38% of the 11 million calls received by ambulance services in England were attended by ambulance but not transported to an Emergency Department (ED). A further 10% received clinical advice over the telephone. Little is known about what happens to patients following a non-transport decision. We aimed to investigate what happens to patients following an emergency ambulance telephone call that resulted in a non-transport decision, using a linked routine data-set. Methods: Six-months individual patient level data from one ambulance service in England, linked with Hospital Episode Statistics and national mortality data, were used to identify subsequent health events (ambulance re-contact, ED attendance, hospital admission, death) within 3 days (primary analysis) and 7 days (secondary analysis) of an ambulance call ending in non-transport to hospital. Non-clinical staff used a priority dispatch system e.g. Medical Priority Dispatch System to prioritize calls for ambulance dispatch. Non-transport to ED was determined by ambulance crew members at scene or clinicians at the emergency operating center when an ambulance was not dispatched (telephone advice). Results: The data linkage rate was 85% for patients who were discharged at scene (43,108/50,894). After removal of deaths associated with end of life care (N = 312), 9% (3,861/42,796) re-contacted the ambulance service, 12.6% (5,412/42,796) attended ED, 6.3% (2,694/42,796) were admitted to hospital, and 0.3% (129/42,796) died within 3 days of the call. Rates were higher for events occurring within 7 days. For example, 12% re-contacted the ambulance service, 16.1% attended ED, 9.3% were admitted to hospital, and 0.5% died. The linkage rate for telephone advice calls was low because ambulance services record less information about these patients (24% 2,514/10,634). A sensitivity analysis identified a range of subsequent event rates: 2.5-10.5% of patients were admitted to hospital and 0.06-0.24% of patient died within 3 days of the call. Conclusions: Most non-transported patients did not have subsequent health events. Deaths after non-transport are an infrequent event that could be selected for more detailed review of individual cases, to facilitate learning and improvement.

Abstract
OBJECTIVE To determine whether ambulance arrival to the emergency department has remained an unidentified signal of perceived medical acuity. Informed by economic signaling theory, does arrival via ambulance affect resource utilization given varying levels of patient acuity? METHODS The analysis examined a nationally representative sample of de-identified emergency department patient encounters from 2011 to 2015, gathered from the National Hospital Ambulatory Medical Care Survey (NHAMCS). Multivariate logistic regression analysis was employed using regional and time-fixed effects. The provision of twenty diagnostic and imaging services was analyzed. Patient encounters were also categorized into five acuity-levels. RESULTS Drawing from the NHAMCS dataset, 98,888 emergency department records were analyzed, weighted to represent 504.5 million estimated emergency department patient encounters. Findings suggest that patients transported to the hospital via ambulance are more likely than those who arrive by other means to receive 19 of the 20 analyzed diagnostic testing and imaging services. Furthermore, when analyzed by acuity-level, the disparity of service provision is the greatest among low-acuity patients, where medical complaints are argued to be the most subjective. CONCLUSIONS The results are consistent with the notion that emergency department medical providers readily accept ambulance transport as a valid signal of patient acuity, regardless of true acuity level. Consequently, patients transported to the hospital via ambulance may be receiving a disproportionate amount of medical resources in an increasingly cost-conscious environment.

Abstract
OBJECTIVES Many police officers receive medical training for limited assessments and interventions. In most situations where medical issues arise, however, emergency medical services (EMS) are called for evaluation, treatment, and transport. Given the limited amount of information about such encounters we examined officer calls for EMS help in a single system to better describe these encounters. METHODS Requests for medical help from a fire-based EMS system by police in a moderate-sized city in 2014 and 2015 were identified. In this system, fire department resources are requested for initial evaluations of any medical complaint. Data were extracted from fire records including disposition, transportation from scene, type of injury or illness, and vital signs. Data analysis used descriptive statistics. RESULTS 4,792 calls were made, representing 2.2% of all police-citizen interactions and 4.2% of all EMS calls. A total of 61.2% of calls resulted in transport to hospital. Of those, 5.6% required fire-based advanced life support; the remainder were transported by private basic life support ambulance or non-medical means. Most requests were for trauma (51.4%), followed by medical (24.7%), drug/alcohol use (17.1%), and psychiatric (6.7%). Vital signs tended to be within normal limits including 72.7% of pulses, 65.1% of systolic blood pressures, and 90.5% of respiratory rates. CONCLUSION Requests for EMS assistance from police were common. Most calls involved patients with normal vital signs who did not require advanced life support transport. Further research is needed to identify situations where increased officer training and change in protocols could potentially change EMS response models and improve efficiency of the system.

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.

[PMID: 28720720 DOI: 10.1136/emermed-2015-205304] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2015] [Revised: 04/21/2017] [Accepted: 05/04/2017] [Indexed: 11/03/2022]
Abstract
OBJECTIVE There is lack of scientific evidence regarding the effectiveness of prehospital triage systems. This study compared the two-level Taiwan Prehospital Triage System (TPTS) with the five-level Taiwan Triage and Acuity Scale (TTAS) at ED arrival regarding the prediction of patient outcomes and the utilisation of medical resources. DESIGN This was a retrospective cohort study. Adult patients transported via the emergency medical service (EMS), who arrived at the ED of a medical centre in northern Taiwan during the study period were enrolled. TTAS acuity levels 1-2 were considered comparable to the designation of 'emergent' by the prehospital TPTS system. The outcomes were analysed by comparing TPTS and TTAS by acuity levels. RESULTS Among 4430 enrolled patients, 25.2% and 74.8% were classified as emergent and non-emergent by TPTS; 44.1% and 55.9% were classified as levels 1-2 and levels 3-5 by TTAS. Of the TPTS emergent patients, 15.2% were classified as TTAS levels 3-5, whereas 30.4% of TPTS non-emergent transports were classified as TTAS levels 1-2 at the ED. TTAS levels 1-2 showed better predictability than TPTS emergent level for hospitalisation rate with a sensitivity of 70.3% (95% CI 68.3% to 72.2%) versus 41.1% (95% CI 39.0% to 43.2%), and a negative predictive value of 74.8% (95% CI 73.4% to 76.0%) versus 62.6% (95% CI 61.7% to 63.5%). CONCLUSION The current prehospital triage system is insufficient and inappropriate in classifying patients transported to the ED. The present study offers supporting evidence for the introduction of a five-level triage system to prehospital EMS systems.

A patient-safety and professional perspective on non-conveyance in ambulance care: a systematic review. Scand J Trauma Resusc Emerg Med 2017; 25:71. [PMID: 28716132 PMCID: PMC5513207 DOI: 10.1186/s13049-017-0409-6] [Citation(s) in RCA: 104] [Impact Index Per Article: 14.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2017] [Accepted: 06/22/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND This systematic review aimed to describe non-conveyance in ambulance care from patient-safety and ambulance professional perspectives. The review specifically focussed at describing (1) ambulance non-conveyance rates, (2) characteristics of non-conveyed patients, (3) follow-up care after non-conveyance, (4) existing guidelines or protocols, and (5) influencing factors during the non-conveyance decision making process. METHODS We systematically searched MEDLINE, PubMed, CINAHL, EMBASE, and reference lists of included articles, in June 2016. We included all types of peer-reviewed designs on the five topics. Couples of two independent reviewers performed the selection process, the quality assessment, and data extraction. RESULTS We included 67 studies with low to moderate quality. Non-conveyance rates for general patient populations ranged from 3.7%-93.7%. Non-conveyed patients have a variety of initial complaints, common initial complaints are related to trauma and neurology. Furthermore, vulnerable patients groups as children and elderly are more represented in the non-conveyance population. Within 24 h-48 h after non-conveyance, 2.5%-6.1% of the patients have EMS representations, and 4.6-19.0% present themselves at the ED. Mortality rates vary from 0.2%-3.5% after 24 h, up to 0.3%-6.1% after 72 h. Criteria to guide non-conveyance decisions are vital signs, ingestion of drugs/alcohol, and level of consciousness. A limited amount of non-conveyance guidelines or protocols is available for general and specific patient populations. Factors influencing the non-conveyance decision are related to the professional (competencies, experience, intuition), the patient (health status, refusal, wishes and best interest), the healthcare system (access to general practitioner/other healthcare facilities/patient information), and supportive tools (online medical control, high risk card). CONCLUSIONS Non-conveyance rates for general and specific patient populations vary. Patients in the non-conveyance population present themselves with a variety of initial complaints and conditions, common initial complaints or conditions are related to trauma and neurology. After non-conveyance, a proportion of patients re-enters the emergency healthcare system within 2 days. For ambulance professionals the non-conveyance decision-making process is complex and multifactorial. Competencies needed to perform non-conveyance are marginally described, and there is a limited amount of supportive tools is available for general and specific non-conveyance populations. This may compromise patient-safety.

Abstract
INTRODUCTION This comprehensive review synthesizes the existing literature on the Patient Protection and Affordable Care Act (ACA) as it relates to emergency medical services (EMS) in order to provide guidance for navigating current and future healthcare changes. METHODS We conducted a comprehensive review to identify all existing literature related to the ACA and EMS and all sections within the federal law pertaining to EMS. RESULTS Many changes enacted by the ACA directly affect emergency care with potential indirect effects on EMS systems. New Medicaid enrollees and changes to existing coverage plans may alter EMS transport volumes. Reimbursement changes such as adjustments to the ambulance inflation factor (AIF) alter the yearly increases in EMS reimbursement by incorporating the multifactor productivity value into yearly reimbursement adjustments. New initiatives, funded by the Center for Medicare & Medicaid Innovation are exploring novel and cost-effective prehospital care delivery opportunities while EMS agencies individually explore partnerships with healthcare systems. CONCLUSION EMS systems should be aware of the direct and indirect impact of ACA on prehospital care due to the potential for changes in financial reimbursement, acuity and volume changes, and ongoing new care delivery initiatives.

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

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
The emergency care system is an essential part of the US health care system. In addition to providing acute resuscitation and life- and limb-saving care, the emergency care system provides considerable support to physicians outside the emergency department and serves as an important safety-net provider. In times of disaster, the emergency care system must be able to surge rapidly to accommodate a massive influx of patients, sometimes with little or no notice. Extreme daily demands on the system can promote innovations and adaptations that are invaluable in responding to disasters. However, excessive and inappropriate utilization is wasteful and can diminish "surge capacity" when it is most needed. Certain features of the US health care system have imposed strains on the emergency care system. We explore policy issues related to moving toward an emergency care system that can more effectively meet both individuals' needs for acute care and the broader needs of the community in times of disaster. Strategies for the redesign of the emergency care system must include the active engagement of both patients and the community and a close look at how to align incentives to reward quality and efficiency throughout the health care system.

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
OBJECTIVES We sought to test reliability of two approaches to classify adverse events (AEs) associated with helicopter EMS (HEMS) transport. METHODS The first approach for AE classification involved flight nurses and paramedics (RN/Medics) and mid-career emergency physicians (MC-EMPs) independently reviewing 50 randomly selected HEMS medical records. The second approach involved RN/Medics and MC-EMPs meeting as a group to openly discuss 20 additional medical records and reach consensus-based AE decision. We compared all AE decisions to a reference criterion based on the decision of three senior emergency physicians (Sr-EMPs). We designed a study to detect an improvement in agreement (reliability) from fair (kappa = 0.2) to moderate (kappa = 0.5). We calculated sensitivity, specificity, percent agreement, and positive and negative predictive values (PPV/NPV). RESULTS For the independent reviews, the Sr-EMP group identified 26 AEs while individual clinician reviewers identified between 19 and 50 AEs. Agreement on the presence/absence of an AE between Sr-EMPs and three MC-EMPs ranged from κ = 0.20 to κ = 0.25. Agreement between Sr-EMPs and three RN/Medics ranged from κ = 0.11 to κ = 0.19. For the consensus/open-discussion approach, the Sr-EMPs identified 13 AEs, the MC-EMP group identified 18 AEs, and RN/medic group identified 36 AEs. Agreement between Sr-EMPs and MC-EMP group was (κ = 0.30 95%CI -0.12, 0.72), whereas agreement between Sr-EMPs and RN/medic group was (κ = 0.40 95%CI 0.01, 0.79). Agreement between all three groups was fair (κ = 0.33, 95%CI 0.06, 0.66). Percent agreement (58-68%) and NPV (63-76%) was moderately dissimilar between clinicians, while sensitivity (25-80%), specificity (43-97%), and PPV (48-83%) varied. CONCLUSIONS We identified a higher level of agreement/reliability in AE decisions utilizing a consensus-based approach for review rather than independent reviews.

Abstract
OBJECTIVE To conduct a systematic review and meta-analysis to examine the impact of new prehospital practitioners (NPPs), including emergency care practitioners (EmCPs), paramedic practitioners and extended care paramedics (ECPs), on ambulance transportation to the emergency department (ED). METHODS We searched MEDLINE, Embase, CINAHL and AUSTHealth databases, and hand searched emergency medicine journals and journal reference lists for relevant papers. To be included, studies were required to target one type of NPP and compare outcomes such as the frequencies of conveyance to the ED, discharge at scene, subsequent ED attendance and/or appropriateness of care between NPPs and conventional ambulance crews. Three investigators independently selected relevant studies. The risk of bias in individual studies was assessed using a validated checklist. We conducted meta-analyses for comparisons which had acceptable heterogeneity (I(2)<75%) and reported pooled estimates of ORs with 95% CIs. RESULTS 13 studies were identified from 16 584 citation reports. EmCPs were most frequently studied. The majority of studies (77%) did not fully report important potential confounders. NPPs were less likely to convey patients to the ED and more likely to discharge patients at the scene than conventional ambulance crews. Pooled ORs for conveyance to the ED and discharge at the scene by ECPs were 0.09 (95% CI 0.04 to 0.18) and 10.5 (95% CI 5.8 to 19), respectively. The evidence for subsequent ED attendance and appropriateness of care was equivocal. CONCLUSIONS The NPP schemes reduced transport to the ED; however, the appropriateness of the decision of the NPPs and the safety of patients were not well supported by the reported studies.

Morganti KG, Alpert A, Margolis G, Wasserman J, Kellermann AL. Should payment policy be changed to allow a wider range of EMS transport options? Ann Emerg Med 2013; 63:615-626.e5. [PMID: 24209960 DOI: 10.1016/j.annemergmed.2013.09.025] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2013] [Revised: 09/10/2013] [Accepted: 09/18/2013] [Indexed: 10/26/2022]
Abstract
The Institute of Medicine and other national organizations have asserted that current payment policies strongly discourage emergency medical services (EMS) providers from transporting selected patients who call 911 to non-ED settings (eg, primary care clinics, mental health centers, dialysis centers) or from treating patients on scene. The limited literature available is consistent with the view that current payment policies incentivize transport of all 911 callers to a hospital ED, even those who might be better managed elsewhere. However, the potential benefits and risks of altering existing policy have not been adequately explored. There are theoretical benefits to encouraging EMS personnel to transport selected patients to alternate settings or even to provide definitive treatment on scene; however, existing evidence is insufficient to confirm the feasibility or safety of such a policy. In light of growing concerns about the high cost of emergency care and heavy use of EDs, assessing EMS transport options should be a high-priority topic for outcomes research.

Abstract
INTRODUCTION The prehospital emergency care has had a rapid progress in Sweden in terms of technology, treatments and personnel education demands. In the County of Skane there is at least one specialized nurse in every ambulance. Possible misuses of the resources by the public have been acknowledged. AIM To investigate the public's use, knowledge and expectations of the prehospital emergency care in Skane, southern Sweden. METHOD A cross sectional descriptive survey, using a stratified sampling. Inclusion criteria were: 18 year or older and currently living in Skane. RESULTS Of 735 people who were asked 54.4% (n=400) chose to participate in the study. 44.0% of the respondents had been transported with ambulance. 34.5% of the respondents believed that the lowest educated personnel responsible for the patient was the paramedic. The results show that the respondents trust the personnel's knowledge and work skills. Older informants expected faster treatment by a physician when arriving by ambulance to the hospital, regardless of medical condition. CONCLUSION The public had confidence in the ambulance personnel's knowledge, ability to make assessment and give treatment despite not being updated on the current competence of the personnel. A positive experience of contact with the ambulance service was distinct.

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
The purpose of this study was to generate national estimates of the prevalence of medically unnecessary emergency medical services (EMS) transports to emergency departments (EDs) over time and to identify characteristics that may be associated with medically unnecessary transports. A previously published algorithm was applied to operationalize medical necessity based on ED diagnosis to 10 years of data from the National Hospital Ambulatory Medical Care Survey. The trend over time was reported using descriptive statistics weighted to produce national estimates. Nationally, the proportion of EMS transports that were medically unnecessary increased from 13% to 17% over the 10-year study period. Individual demographic characteristics, including insurance status, were not predictive of inappropriate utilization. EMS transports for medically unnecessary complaints increased from 1997 to 2007. Our findings from a nationally representative sample highlight the opportunity for alternative patient delivery strategies for select patients seeking EMS services.

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
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 Recent government policy has looked at improving the role of ambulance services in delivering alternative care models for patients. OBJECTIVE To review the outcomes of the introduction of some specific non-transport guidelines into an ambulance service. METHODS A retrospective review was undertaken of the documentation produced from the use of these protocols in the first 4 months following introduction for appropriateness of use, and potential for risk of adverse outcome. RESULTS Of 354 uses of the guidelines, 140 (39.5%) were considered inappropriate. A large number of these were cases where the issue was refusal of transport rather than a use of the guideline. Of the rest the more focused guidelines showed better adherence (hypoglycaemia 2/69 inappropriate, epilepsy 1/23 inappropriate) than the more non-specific guidelines (no apparent injury 17/84 inappropriate, minor limb injury 28/58 inappropriate). CONCLUSIONS This short study suggests that focused guidelines can help support ambulance staff decision making; however, care must be taken to ensure safe practice and that these guidelines are not used to add legitimacy to poor practice.

Abstract
OBJECTIVES To evaluate the setting of priorities and patients' need for the ambulance service. METHODS A prospective, consecutive study was conducted during a 6-week period. The ambulance staff completed a questionnaire assessing each patient's need for prehospital care. In addition to the questionnaire, data were extracted from the ambulance medical records for each case. RESULTS The study included 1977 ambulance assignments. The results show that there is a substantial safety margin in the priority assessments made by the emergency medical dispatch operators, where the ambulance staff support the safety margin for initial priorities, despite the lack of at-the-scene confirmation. At-the-scene assessments indicated that 10% of all patients had potentially life-threatening conditions or no signs of life, but the advanced life support units were not systematically involved in these serious cases. The results even showed that one-third of the patients for whom an ambulance was assigned did not need the ambulance service according to the assessment made by the ambulance staff. CONCLUSION Using the criteria-based dispatch protocol, the personnel at the emergency medical dispatch centres work with a safety margin in their priority assessments for ambulance response. Generally, this 'overtriage' and safety margin for initial priority settings were supported as appropriate by the ambulance staff. According to the judgement of the ambulance staff, one-third of all the patients who were assigned an ambulance response did not require ambulance transport.

Abstract
OBJECTIVE To examine interrater agreement for classifying emergency medical services transports as medically unnecessary using emergency department diagnosis as the sole determining factor. METHODS Three emergency physicians and two family medicine physicians classified 913 International Classification of Diseases, Ninth Revision (ICD-9) codes as medically necessary, unnecessary, or uncertain. Overall agreement, interrater agreement, and agreement within 17 major disease categories were measured using kappa statistics in SAS. RESULTS Physicians rated between 25% and 65% of diagnoses codes as medically unnecessary. Overall agreement was fair (kappa = 0.31). Agreement within specialties was higher among family medicine-trained physicians than among emergency physicians (kappa = 0.52 and kappa = 0.22, respectively). Agreement across all raters was highest for diseases classified as symptoms, signs, and ill-defined conditions (kappa = 0.40) and lowest for diseases of the blood and blood-forming organs (kappa = -0.17). Agreement was observably better between physicians with more experience. CONCLUSIONS Considerable doubts about the utility of emergency department diagnosis as a criterion are raised from study findings. Further development of Neely Conference criteria is needed. Priority should be given to testing and validation of criteria as well as exploration of differences in judgment between specialists representative of the medical director profession.

Abstract
INTRODUCTION In a time of emergency department overcrowding and increased utilization of emergency medical services, a highly functional prehospital system will balance the needs of the individual patient with the global needs of the community. Our community addressed these issues through the development of a multitiered prehospital care system that incorporated EMS initiated non-transport of pediatric patients. OBJECTIVE To describe the outcome of pediatric patients accessing a progressive prehospital system that employed EMS initiated non-transport. METHODS A prospective observational case series was performed on pediatric patients (< 21 years old) designated EMS initiated non-transport. Patients were designated non-transport after an initial EMS protocol driven, complaint-specific clinical assessment in conjunction with medical oversight affirmation. Telephone follow-up was completed on all consecutively enrolled non-transport patients to collect information about outcome (safety) as well as overall satisfaction with the system. A five-point Likert scale was utilized to rate satisfaction. RESULTS There were 5,336 EMS requests during the study period. Seven hundred and four were designated non-transport, of which 74.8% completed phone follow-up. Categories of EMS request included minor; medical illness 43.4%, trauma 55.9%, and other 1.1%. There were 13 admissions (2.4%) to the hospital after EMS initiated non-transport designation. Admissions after non-transport had trends toward younger age (p = 0.002) and medical etiology (p = 0.006). There were no PICU admissions or deaths. CONCLUSION Our EMS system provides an alternative to traditional protocols, allowing EMS initiated non-transport of pediatric patients, resulting in effective resource utilization with a high level of patient safety and family satisfaction.

Abstract
OBJECTIVES Estimate the prevalence of medically unnecessary Emergency Medical Services (EMS) transports among children. METHODS We linked EMS and emergency department (ED) billing records for all EMS-to-hospital transports of children originating in three counties in South Carolina between January 1, 2001 and March 31, 2003. EMS responses resulting in no transport, transports to destinations other than the ED, or multiple trips for the same child in a single day could not be linked to ED data and were excluded. Medically unnecessary transports were identified with an algorithm using pre-hospital impressions, ED diagnoses and ED procedures. After exclusions, 5,693 transports of children between 0 and 17 years were available for study. RESULTS Sixteen percent (16.4%) of all transports were medically unnecessary. Among children through age 12, upper respiratory and viral problems were the most common diagnoses associated with medically unnecessary transports; among older children, behavioral problems such as conduct disturbance or drug abuse were common. In multivariable analysis, the odds of an unnecessary transport were higher among younger children, non-white children, rural children, and children insured by Medicaid. CONCLUSIONS The proportion of EMS transports which may be medically unnecessary is relatively modest compared to previous studies. However, many questions remain for future research. Further investigation should include examination of primary care availability and occurrence of unnecessary EMS use, existence of race-based disparities, and transports involving conduct disturbance and other behavioral conditions among children.

Abstract
OBJECTIVES To test a hypothesis that patients would accept alternatives to transport to an emergency department (ED) by ambulance and to evaluate factors related to patient willingness to consider alternatives. Concerns about resource utilization have prompted emergency medical services (EMS) systems to explore alternatives to ambulance transport to an ED, but studies have evaluated the safety of alternatives, not patient preferences. METHODS Trained research assistants surveyed patients transported by ambulance to a university ED. Interfacility transfers, trauma patients, and critically ill patients were excluded. The primary outcome was willingness to accept one of several presented alternatives to ambulance transport to the ED for that visit. Demographic and clinical factors were evaluated for association with willingness to consider alternatives. Relative risks (RR) and 95% confidence intervals (95% CI) were determined by using Mantel-Haenszel stratified methods. RESULTS Three hundred fifteen subjects completed the survey. Two hundred forty-seven (78.4%) were willing to consider at least one alternative. One hundred ninety-four (61.6%) were willing to consider transportation by car, and 177 (56.2%) were willing to consider transportation by taxi. Factors associated with willingness to consider alternatives included the following: age 18-65 years (RR, 1.25; 95% CI = 1.03 to 1.49), being unemployed (RR, 1.08; 95% CI = 1.08 to 1.33), use of the ED for routine care (RR, 1.25; 95% CI = 1.17 to 1.35), and not being admitted to the hospital (RR, 1.19; 95% CI = 1.04 to 1.40). Race, gender, health insurance status, and EMS interventions en route were not associated with willingness to consider transportation alternatives. CONCLUSIONS Many patients transported by ambulance to an ED would have considered an alternative, if one were offered.

Abstract
The issue of the inappropriate use of ambulance transport and care has mainly been studied from the professionals' and caregivers' perspective, with few studies focusing on the patient and his/her experiences. To further understand whether patients use ambulance care in an inappropriate manner and, if so, why, it is important to obtain an overall picture of the patients' existential situation at the time they call an ambulance. The aim of this study was to analyse and describe patients' experiences related to the decision to call an ambulance and the wait for it to arrive. The design was explorative, and twenty informants aged between 34 and 82 years were interviewed. Qualitative content analyses were performed. The findings showed that calling for an ambulance is a major decision that is preceded by hesitation and attempts to handle the situation by oneself. Our conclusion is that the definition of inappropriate use of valuable health care resources should not be based solely on the professionals' point of view but also take account of the patients' reactions when they experience a threat to their life and health.
