Medical necessity in emergency medical services transports

Characteristics of consecutive versus non-consecutive frequent emergency medical services transport to a single emergency department

OBJECTIVE

This study was to examine characteristics concerning frequent users of emergency medical services (EMS) transport by comparing patients who used EMS transport frequently for one year and those who used EMS transport for more than two years consecutively.

METHODS

A retrospective review for frequent use of EMS transport was conducted. The patients from the fire stations that transported more than 70% of all EMS transport to the study hospital emergency department (ED) were included. The study subjects were divided into consecutive group (frequent EMS transport for ≥ two years consecutively) and non-consecutive group (frequent EMS transport for only one year). Characteristics of patients who were frequent users of EMS transport and those of all cases with EMS transport were examined.

RESULTS

Of the total 205 patients and 1204 cases of frequent EMS transport, 85 (42%) patients and 755 (63%) cases were in the consecutive group. Patients in the consecutive group were more likely to have risky alcohol use, unemployed state, and medical aid type of payment for ED treatment than those in the non-consecutive group. More patients had previous experience of EMS transport to the study hospital ED in the consecutive group and the number of cases with alcohol ingestion was higher in the consecutive group. Elapsed time from EMS call to ED arrival was longer for the consecutive group.

CONCLUSION

Risky alcohol use, unemployed state, and previous experience of EMS transport were associated with consecutive and frequent use of EMS transport in frequent users of EMS transport.

Paramedic Education and Training for the Management of Patients Presenting with Low-Acuity Clinical Conditions: A Scoping Review

Ambulance services around the world are increasingly attending to calls for non-emergency conditions. These lower-acuity conditions do not always require patients to be transported to the emergency department. Consequently, over the past two decades, ambulance services have implemented strategies to support paramedics in diverting non-urgent patients to alternative care pathways. However, assessing and managing low-acuity conditions can be challenging for paramedics, especially when education and training has traditionally focussed on emergency care. This scoping review explores the education and training provided to paramedics on low-acuity clinical conditions and the use of alternative care pathways. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews was applied. The databases searched included Scopus, CINAHL, Embase, Emcare, and MEDLINE (PubMed). The search identified one-hundred sixty-six records, with a total of nine articles reviewed after the removal of duplicates and the screening process. The articles were diverse, with education and training ranging from university degrees for extended care practitioners to short in-service-based training for a suite of protocols or assessment tools. However, the literature addressing education and training on low-acuity conditions and alternative care pathways is limited, with the type and length of education programs appearing to influence practice. There is a need for further research to establish a low acuity education model.

Effects of Closure of the Paediatric Department of a District Hospital on Regional Care: Analysis of Patient Flows

BACKGROUND

The consequences of economization and staff shortage in the German health care system strongly affect paediatric care structures, especially in rural regions. It is not known how closures of paediatric departments influence patient flows of surrounding hospitals. Here, we investigate the quantitative effects of closure of the paediatric department of a district hospital and the subsequent opening of an alternative inpatient service on the utilisation of inpatient and outpatient care services of the two neighboring hospitals and the emergency services of the region.

METHODOLOGY

In the observation period from 2015 to 2019, patient-related data from the three hospitals in the study region as well as data from the rescue service were evaluated.

RESULTS

In the year after the paediatric department of the district hospital was closed in 2016, the total number of inpatient cases in the region decreased by 33% (2015: n=1,787; 2016: n=1,193) and then decreased by an additional 11% (2019: n=1,005). The number of outpatient cases decreased by further 8% (2015: n=6,250; 2019: n=5,770). In the last observation year, emergency services were used much more frequently than in the year before the closure (2015: n=398; 2019: n=572). This means an increase of 44%.

CONCLUSION

After the closure of the paediatric department, the total number of inpatient cases in the region fell sharply. However, actual gaps in care apparently did not arise. Before closing, the consequences for the surrounding hospitals should be assessed more precisely. Real gaps in care must be counteracted, e. g. through alternative outpatient services.

Clinician and Caregiver Determinations of Acuity for Children Transported by Emergency Medical Services: A Prospective Observational Study

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.

Paramedic Education to Support the Use of Low-Acuity Care Pathways: A Scoping Review Protocol

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.

Apart from the Medical Complaints, Why do Patients Use Emergency Medical Services? Results of a Patient Survey

INTRODUCTION

Many countries face an increased use of emergency medical services (EMS) with a decreasing percentage of life-threatening complaints. Though there is a broad discussion among experts about the cause, patients' self-perceived, non-medical reasons for using EMS remain largely unknown.

METHODS

The written survey included EMS patients who had≥1 case of prehospital emergency care in 2016. Four German health insurance companies sent out postal questionnaires to 1312 insured patients. The response rate was 20%; 254 questionnaires were eligible for descriptive and interferential analyses (t-tests, chi2-tests, logistic models).

RESULTS

The majority of respondents indicated that their EMS use was due to an emergency or someone else's decision (≥84%; multiple checks allowed); 56% gave need for a quick transport as a reason. Other frequently stated reasons addressed the health care system (e. g., complaints outside of physicians' opening hours) and insecurity/anxiety about one's state of health (>45% of the respondents). "Social factors" were similarly important (e. g., 42% affirming, "No one could give me a ride to the emergency department or doctor's office."). Every fifth person had contact with other emergency care providers prior to EMS use. Respondents negating an emergency as a reason were less likely to confirm wanting immediate medical care on site or quick transports compared to those affirming an emergency. Patients using EMS at night more often denied having an emergency compared to patients with access to care during the day.

CONCLUSION

The study identified a bundle of reasons leading to EMS use apart from medical complaints. Attempts for needs-oriented EMS use should essentially include optimization of the health care and social support system and measures to reduce patients' insecurity.

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

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.

Evaluation of an EMS-based community paramedic pilot program to reduce frequency of 9-1-1 calls among high utilizers

Background - Many community paramedic interventions aim to reduce unnecessary emergency department visits among high utilizers of acute care, but fewer focus specifically on reducing summons for emergency medical services (EMS). We implemented an EMS-based pilot program that identified high utilizers of 9-1-1 and facilitated community paramedic outreach encounters to understand and address potentially unnecessary 9-1-1 calls. This study compares the pre- and post-intervention incidence rate of 9-1-1 calls among program participants.Methods - This retrospective evaluation was conducted using pilot data from a single U.S. EMS agency that responds to approximately 100,000 9-1-1 calls annually. High utilizers, defined as individuals with ≥3 9-1-1 calls in 90 days, were identified for recruitment between February 1, 2019 and December 31, 2019. community paramedics recruited participants via phone and then conducted home visits to assist them with navigation away from unnecessary 9-1-1 use. Dispatch data from September 1, 2018 to December 31, 2019 were used to compute the incidence rate of 9-1-1 calls per 30 person-days of observation before and after the initial home visits.Results - Data from 108 program participants were analyzed. The majority were over the age of 50 (79%), and 33% completed more than one visit. Median person-days of observation before and after the initial home visit were 354 days and 132 days, respectively. Participants called 9-1-1 an average of 0.68 times per 30 person-days prior to the community paramedic intervention, and 0.51 times per 30 person-days after the intervention, which represents an overall mean decrease in 9-1-1 utilization of 25% (p < 0.001). Although a decrease in 9-1-1 utilization was observed in the majority of participants, the 9-1-1 call rate increased in 29% of participants. No statistically significant changes in 9-1-1 use were observed in participants who received more than one home visit or who were in the highest quartile of 9-1-1 use prior to the intervention.Conclusion - This pilot work demonstrates the feasibility of an EMS-based, community paramedic-only intervention to reduce unnecessary 9-1-1 calls and suggests that some modest reductions in EMS use may be achievable by dispatching community paramedics to conduct home visits with frequent users of 9-1-1.

Which health-related reasons lead to prehospital emergency care and how does subjective emergency status connect to subsequent care?

Objectives/Background

In many countries, the use of emergency medical services (EMS) increases steadily each year. At the same time, the percentage of life-threatening complaints decreases. To redesign the system, an assessment and consideration of the patients’ perspectives is helpful.

Methods

We conducted a paper-based survey of German EMS patients who had at least one case of prehospital emergency care in 2016. Four health insurance companies sent out the questionnaire to 1312 insured persons. We linked the self-reported data of 254 respondents to corresponding claims data provided by their health insurance companies. The analysis focuses a.) how strongly patients tend to call EMS for themselves and others given different health-related scenarios, b.) self-perceived health complaints in their own index case of prehospital emergency care and c.) subjective emergency status in combination with so-called “objective” characteristics of subsequent EMS and inpatient care. We report principal diagnoses of (1) respondents, (2) 57,240 EMS users who are not part of the survey and (3) all 20,063,689 inpatients in German hospitals. Diagnoses for group 1 and 2 only cover the inpatient stay that started on the day of the last EMS use in 2016.

Results

According to the survey, the threshold to call an ambulance is lower for someone else than for oneself. In 89% of all cases during their own EMS use, a third party called the ambulance. The most common, self-reported complaints were pain (38%), problems with heart and circulation (32%), and loss of consciousness (17%). The majority of respondents indicated that their EMS use was due to an emergency (89%). We could detect no or only weak associations between patients’ subjective urgency and different items for objective care.

Conclusion

Dispatchers can possibly optimize or reduce the disposition of EMS staff and vehicles if they spoke directly to the patients more often. Nonetheless, there is need for further research on how strongly the patients’ perceived urgency may affect the disposition, rapidness of the service and transport targets.

An Integrated Mobile Acute Care Service Enhances Value

Reducing the cost of care while enhancing its quality and experience are essential components to success in value-based care. Because emergency department (ED) and hospital settings represent high-cost environments, the authors sought to reduce their unnecessary use by deploying a novel care delivery service that offers mobile, on-demand care for high-acuity conditions in patient homes. This study is a retrospective quality improvement evaluation of the initial year of the mobile acute care model in a health system with a substantial penetration of value-based care. Although all patients were eligible for mobile services as clinically indicated, those in accountable care organizations were prioritized by the care management teams. A variety of operational, clinical, and financial metrics were assessed to determine the program's performance and value. There were 3436 patient encounters during the study period, a utilization rate of 71% that trended upward throughout the year. Of these visits, 44% involved patients in value-based payment models; 80% of these represented patients in Medicare risk agreements. Throughout the year, progressively improving operational and clinical performance were observed, as were consistently high patient satisfaction scores. An estimated 63.8% of total mobile visits resulted in ED avoidance; 21.6% were emergency medical transport avoidant; 14.1% led to avoided hospital observation or inpatient stays. Patients were highly satisfied with the service. In-home mobile care for high-acuity illness can prevent unnecessary ED and hospital use for some patients and is associated with high patient satisfaction. Acute mobile care is a useful component of a value-based care strategy.

EMS utilization predictors in a Mobile Integrated Health (MIH) program

BACKGROUND

The provision of unnecessary Emergency Medical Services care remains a challenge throughout the US and contributes to Emergency Department overcrowding, delayed services and lower quality of care. New EMS models of care have shown promise in improving access to health services for patients who do not need urgent care. The goals of this study were (1) to identify factors associated with EMS utilization (911) and (2) their effects on total EMS calls and transports in an MIH program.

METHODS

The study sample included 110 MIH patients referred to the program or considered high-users of EMS services between November 2016 and September 2018. The study employed descriptive statistics and Poisson regressions to estimate the effects of covariates on total EMS calls and transports.

RESULTS

The typical enrollee is a 60-year-old single Black male living with two other individuals. He has a PCP, takes 12 medications and is compliant with his treatment. The likelihood of calling and/or being transported by EMS was higher for males, patients at high risk for falls, patients with asthma/COPD, psychiatric or behavioral illnesses, and longer travel times to a PCP. Each prescribed medication increased the risk for EMS calls or transports by 4%. The program achieved clear reductions in 911 calls and transports and savings of more than 140,000 USD in the first month.

CONCLUSIONS

This study shows that age, marital status, high fall risk scores, the number of medications, psychiatric/behavioral illness, asthma/COPD, CHF, CVA/stroke and medication compliance may be good predictors of EMS use in an MIH setting. MIH programs can help control utilization of EMS care and reduce both EMS calls and transports.

Using trigger tools to identify triage errors by ambulance dispatch nurses in Sweden: an observational study

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.

Telehealth Impact on Primary Care Related Ambulance Transports

Introduction: Telehealth has been used nominally for trauma, neurological, and cardiovascular incidents in prehospital emergency medical services (EMS). Yet, much less is known about the use of telehealth for low-acuity primary care. We examine the development of one telehealth program and its impact on unnecessary ambulance transports. Objective: The objective of this study is to describe the development and impact of a large-scale telehealth program on ambulance transports. Methods: We describe the patient characteristics and results from a cohort of patients in Houston, Texas who received a prehospital telehealth consultation from an emergency medicine physician. Inclusion criteria were adults and pediatric patients with complaints considered to be non-urgent, primary care related. Data were analyzed for 36 months, from January 2015 through December 2017. Our primary dependent variable was the percentage of patients transported by ambulance. We used descriptive statistics to describe patient demographics, chi-square to examine differences between groups, and logistic regression to explore the effects with multivariate controls including age, gender, race, and chief complaint. Results: A total of 15,067 patients were enrolled (53% female; average age 44 years ± 19 years) over the three-year period. The 3 primary chief complaints were based on abdominal pains (13% of cases), nausea/vomiting/diarrhea (NVD) (9.4%), and back pain (9.3%). Ambulance transports represented 11.2% of all transports in the program, while alternative taxi transportation was used in 75.6%, and the remainder were self- or no-transports. Taxi transportation to an alternate, affiliated clinic (versus ED) was utilized in 5% of incidents. After multivariate controls, older age patients presenting with low-risk, non-acute chest pain, shortness of breath, and dizziness were much more likely to use ambulance transport. Race and gender were not significant predictors of ambulance transport. Conclusions: We found telehealth offers a technology strategy to address potentially unnecessary ambulance transports. Based on prior cost-effectiveness analyses, the reduction of unnecessary ambulance transports translates to an overall reduction in EMS agency costs. Telehealth programs offer a viable solution to support alternate destination and alternate transport programs.

Examination of EMS Decision Making in Determining Suitability of Patient Diversion to Urgent Care Centers

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.

Factors Associated With Pediatric Nontransport in a Large Emergency Medical Services System

BACKGROUND

Pediatric patients attended to by emergency medical services (EMS) but not transported to the hospital are an at-risk population. We aimed to evaluate risk factors associated with nontransport by EMS in pediatric patients.

METHODS

We reviewed medical records of 24 agencies in a regional EMS system in Southwestern Pennsylvania between January 1, 2014, and December 31, 2017. We abstracted demographics (age, sex, medical complaint, median household income by zip code, race, ethnicity), clinical characteristics (abnormal vital signs by age, procedures done), and transport characteristics. We excluded patients ≥ 18 years, interfacility transfers, scene assists, cardiac arrest, and those without a patient encounter. We used unadjusted and adjusted logistic regression to identify factors associated with nontransport, reporting adjusted odds ratios (aOR) with 95% confidence intervals (CIs).

RESULTS

We included 30,663 pediatric patients (52.9% male, mean ± SD age = 8.5 ± 6.2 years), of whom 5,002 (16.3%) were nontransports. In adjusted analysis (aOR, 95% CI), nontransports were associated with medical categories of trauma (4.32, 3.57-5.23), respiratory (4.03, 3.09-5.26), toxicologic (2.53, 1.66-3.86), and syncope (5.97, 3.78-9.41). Nontransports were less likely for psychiatric (0.52, 0.34-0.79) complaints; for black patients compared to white (0.31, 0.26-0.37); and in patients 6 to <12 years (0.76, 0.65-0.90), 2 to <6 years (0.77, 0.65-0.91), 1 to <2 years (0.53, 0.42-0.66), and 1 month to 1 year (0.52, 0.40-0.66) compared to patients ≥ 12 years of age. Nontransport was associated with longer scene time (1.03, 1.02-1.04) and with fall compared to winter (1.29, 1.08-1.54) and was less likely in those with abnormal mental status (0.45, 0.33-0.62), medication administration (0.16, 0.08-0.31), or monitor application (0.10, 0.06-0.15).

CONCLUSION

Pediatric nontransports are associated with traumatic, respiratory, and toxicologic complaints and older age. These findings can facilitate development of refusal protocols and research on outcomes of these at-risk patients.

Risk factors related to unnecessary emergency medical services transport for pediatric patients

OBJECTIVES

This study evaluated unnecessary emergency medical services (EMS) transport for pediatric patients depending on whether they received emergency department (ED) treatment after EMS transport.

METHODS

Pediatric patients were divided into two groups according to whether they received treatment at the ED (ED treatment) or did not receive treatment at the ED (non-ED treatment).

RESULTS

The non-ED treatment group comprised 65 of the total 794 patients. The elapsed time from scene to arrival at the ED was longer in the non-ED treatment group than in the ED treatment group. Weekdays as the days of EMS transport, ground falls rather than traffic accidents as the reason for non-disease-related symptoms, and no immobilization for prehospital treatment were risk factors for non-ED treatment in EMS-transported patients. Causes of not receiving ED treatment for the non-ED treatment group were the patient's or caregiver's decision (12%) and the doctor's suggestion (88%).

CONCLUSIONS

Weekdays rather than weekends, ground falls rather than traffic accidents, and no immobilization before hospital are risk factors for not receiving ED treatment. The most common cause of not receiving ED treatment is the doctor's suggestion.

The ambulance nurse experiences of non-conveying patients

Aims and objectives

To explore ambulance nurses' (ANs) experiences of non‐conveying patients to alternate levels of care.

Background

Increases in ambulance utilisation and in the number of patients seeking ambulance care who do not require medical supervision or treatment during transport have led to increased nonconveyance (NC) and referral to other levels of care.

Design

A qualitative interview study was conducted using an inductive research approach.

Methods

The study was conducted in a region in the middle of Sweden during 2016–2017. Twenty nurses were recruited from the ambulance departments in the region. A conventional content analysis was used to analyse the interviews. The study followed the COREQ checklist.

Results

The ANs experienced NC as a complex and difficult task that carried a large amount of responsibility. They wanted to be professional, spend time with the patient and find the best solution for him or her. These needs conflicted with the ANs' desire to be available for assignments with a higher priority. The ANs could feel frustrated when they perceived that ambulance resources were being misused and when it was difficult to follow the NC guidelines.

Conclusion

If ANs are expected to nonconvey patients seeking ambulance care, they need a formal mandate, knowledge and access to primary health care.

Relevance to clinical practice

This study provides new knowledge regarding the work situation of ANs in relation to NC. These findings can guide future research and can be used by policymakers and ambulance organisations to highlight areas that need to evolve to improve patient care.

Appropriateness of cases presenting in the emergency department following ambulance service secondary telephone triage: a retrospective cohort study

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.

Trends in diagnostic patterns and mortality in emergency ambulance service patients in 2007-2014: a population-based cohort study from the North Denmark Region

OBJECTIVE

Demand for ambulances is growing. Nevertheless, knowledge is limited regarding diagnoses and outcomes in patients receiving emergency ambulances. This study aims to examine time trends in diagnoses and mortality among patients transported with emergency ambulance to hospital.

DESIGN

Population-based cohort study with linkage of Danish national registries.

SETTING

The North Denmark Region in 2007-2014.

PARTICIPANTS

Cohort of 148 757 patients transported to hospital by ambulance after calling emergency services.

MAIN OUTCOME MEASURES

The number of emergency ambulance service patients, distribution of their age, sex, hospital diagnoses, comorbidity, and 1-day and 30-day mortality were assessed by calendar year. Poisson regression with robust variance estimation was used to estimate both age-and sex-adjusted relative risk of death and prevalence ratios for Charlson Comorbidity Index (CCI) to allow comparison by year, with 2007 as reference year.

RESULTS

The annual number of emergency ambulance service patients increased from 24.3 in 2007 to 40.2 in 2014 per 1000 inhabitants. The proportions of women increased from 43.1% to 46.4% and of patients aged 60+ years from 39.9% to 48.6%, respectively. The proportion of injuries gradually declined, non-specific diagnoses increased, especially the last year. Proportion of patients with high comorbidity (CCI≥3) increased from 6.4% in 2007 to 9.4% in 2014, corresponding to an age- and sex-adjusted prevalence ratio of 1.27 (95% CI 1.16 to 1.39). The 1-day and 30 day mortality decreased from 2.40% to 1.21% and from 5.01% to 4.36%, respectively, from 2007 to 2014, corresponding to age-adjusted and sex-adjusted relative risk of 0.43 (95% CI 0.37 to 0.50) and 0.72 (95% CI 0.66 to 0.79), respectively.

CONCLUSION

During the 8-year period, the incidence of emergency ambulance service patients, the proportion of women, elderly, and non-specific diagnoses increased. The level of comorbidity increased substantially, whereas the 1-day and 30-day mortality decreased.

Effects of Emergency Medical Services Agency Ownership Status on Patient Transport

OBJECTIVES

Medical insurers have clearly defined which ambulance services will be reimbursed and which will not. Thus, ambulance agencies that provide emergency 9-1-1 services must be highly cognizant of their organization's revenue needs. This presents a distinction between publicly funded and privately funded organizations. This study seeks to identify any differences in the transport decision among agency ownership types.

METHODS

This retrospective study captured all 9-1-1 ambulance requests in the state of Virginia for the years 2009 through 2013. Each request was answered by either a publicly funded ambulance service or a privately funded ambulance service. The outcome variable of interest was patient disposition and the key explanatory variable was organizational ownership type. Multivariate logistic regression was utilized for data analysis.

RESULTS

Of the 4.6 million 9-1-1 requests, approximately 30% were attended to by a private ambulance service. After controlling for potential confounders, ownership type was found to have a statistically significant effect on the transport decision. Private for-profit ambulance services were 4.5 times more likely to transport a patient than were their publicly funded counterparts (OR: 4.56, 95% CI: 4.47-4.65). Private non-profit organizations were twice as likely to engage in patient transport (OR: 2.12, 95% CI: 2.09-2.14). Private for-profit ambulance organizations were also found to be less likely to allow for patient refusal (OR: 0.54, 95% CI: 0.53-0.55) or to medically treat on-scene without subsequent transport (OR: 0.48, 95% CI: 0.45-0.50).

CONCLUSIONS

Given the reimbursement practices of medical insurers, private ambulance services are incentivized towards patient transport. Operational revenue for these services is not generated through public budgeting processes but through user fees. Thus, private agencies are more reliant on billable services than are their publicly funded counterparts.

Unnecessary emergency medical services transport associated with alcohol intoxication

Objective

This study investigated medically unnecessary emergency medical services (EMS) transportation by comparing non-intoxicated versus intoxicated patients who did not receive emergency department (ED) treatment but utilized EMS transport.

Methods

Patients who used EMS but did not receive ED treatment were classified into non-intoxicated and intoxicated groups. Reasons for not receiving ED treatment were categorized according to whether the decision was made by the patient against medical advice or if the decision was based on a physician’s evaluation and their recommendations.

Results

There were 212 patients reviewed; 120 in the non-intoxicated group and 92 in the intoxicated group. The intoxicated group had a higher proportion of males than the non-intoxicated group. The most common cause of non-disease symptoms in the intoxicated group was assault. In the non-intoxicated group, the most common reason for the lack of ED treatment was that treatment could take place on an outpatient basis, while in the intoxicated group, the reason was lack of patient cooperation.

Conclusions

The intoxicated group was older, male and more likely to present with symptoms not related to a disease process than those in the non-intoxicated group when using unnecessary EMS transport.

Challenges and Opportunities to Engaging Emergency Medical Service Providers in Substance Use Research: A Qualitative Study

Introduction Research suggests Emergency Medical Services (EMS) over-use in urban cities is partly due to substance users with limited access to medical/social services. Recent efforts to deliver brief, motivational messages to encourage these individuals to enter treatment have not considered EMS providers. Problem Little research has been done with EMS providers who serve substance-using patients. The EMS providers were interviewed about participating in a pilot program where they would be trained to screen their patients for substance abuse and encourage them to enter drug treatment.

METHODS

Qualitative interviews were conducted with Baltimore City Fire Department (BCFD; Baltimore, Maryland USA) EMS providers (N=22). Topics included EMS misuse, work demands, and views on participating in the pilot program. Interviews were transcribed and analyzed using grounded theory and constant-comparison.

RESULTS

Participants were mostly white (68.1%); male (68.2%); with Advanced Life Skills training (90.9%). Mean age was 37.5 years. Providers described the "frequent flyer problem" (eg, EMS over-use by a few repeat non-emergent cases). Providers expressed disappointment with local health delivery due to resource limitations and being excluded from decision making within their administration, leading to reduced team morale and burnout. Nonetheless, providers acknowledged they are well-positioned to intervene with substance-using patients because they are in direct contact and have built rapport with them. They noted patients might be most receptive to motivational messages immediately after overdose revival, which several called "hitting their bottom." Several stated that involvement with the proposed study would be facilitated by direct incorporation into EMS providers' current workflow. Many recommended that research team members accompany EMS providers while on-call to observe their day-to-day work. Barriers identified by the providers included time constraints to intervene, limited knowledge of substance abuse treatment modalities, and fearing negative repercussions from supervisors and/or patients. Despite reservations, several EMS providers expressed inclination to deliver brief motivational messages to encourage substance-using patients to consider treatment, given adequate training and skill-building.

CONCLUSIONS

Emergency Medical Service providers may have many demands, including difficult case time/resource limitations. Even so, participants recognized their unique position as first responders to deliver motivational, harm-reduction messages to substance-using patients during transport. With incentivized training, implementing this program could be life- and cost-saving, improving emergency and behavioral health services. Findings will inform future efforts to connect substance users with drug treatment, potentially reducing EMS over-use in Baltimore. Maragh-Bass AC , Fields JC , McWilliams J , Knowlton AR .

Areas of Potential Impact of the Patient Protection and Affordable Care Act on EMS: A Synthesis of the Literature

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.

A novel approach for managing the growing demand for ambulance services by low-acuity patients

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.

The US emergency care system: meeting everyday acute care needs while being ready for disasters

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.

Secondary triage in prehospital emergency ambulance services: a systematic review

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.
