The development of community paramedicine; a restricted review

How should non-emergency EMS presentations be managed? A thematic analysis of politicians', policymakers', clinicians' and consumers' viewpoints

OBJECTIVE

In 2023, Australian government emergency medical services (EMS) responded to over 4 million consumers, of which over 56% were not classified as an 'emergency', at the cost of AU$5.5 billion. We explored the viewpoints of politicians, policymakers, clinicians and consumers on how these non-emergency requests should be managed.

DESIGN

A realist framework was adopted; a multidisciplinary team (including paramedicine, medicine and nursing) was formed; data were collected via semistructured focus groups or interviews, and thematic analysis was performed.

SETTING AND PARTICIPANTS

56 participants were selected purposefully and via open advertisement: national and state parliamentarians (n=3); government heads of healthcare disciplines (n=3); government policymakers (n=5); industry policymakers in emergency medicine, general practice and paramedicine (n=6); EMS chief executive officers, medical directors and managers (n=7); academics (n=8), frontline clinicians in medicine, nursing and paramedicine (n=8); and consumers (n=16).

RESULTS

Three themes emerged: first, the reality of the EMS workload (theme titled 'facing reality'); second, perceptions of what direction policy should take to manage this ('no silver bullet') and finally, what the future role of EMS in society should be ('finding the right space'). Participants provided 16 policy suggestions, of which 10 were widely supported: increasing public health literacy, removing the Medical Priority Dispatch System, supporting multidisciplinary teams, increasing 24-hour virtual emergency departments, revising undergraduate paramedic university education to reflect the reality of the contemporary role, increasing use of management plans for frequent consumers, better paramedic integration with the healthcare system, empowering callers by providing estimated wait times, reducing ineffective media campaigns to 'save EMS for emergencies' and EMS moving away from hospital referrals and towards community care.

CONCLUSIONS

There is a need to establish consensus on the role of EMS within society and, particularly, on whether the scope should continue expanding beyond emergency care. This research reports 16 possible ideas, each of which may warrant consideration, and maps them onto the standard patient journey.

The Economic Impact of Community Paramedics Within Emergency Medical Services: A Systematic Review

BACKGROUND AND OBJECTIVE

Globally, emergency medical services (EMSs) report that their demand is dominated by non-emergency (such as urgent and primary care) requests. Appropriately managing these is a major challenge for EMSs, with one mechanism employed being specialist community paramedics. This review guides policy by evaluating the economic impact of specialist community paramedic models from a healthcare system perspective.

METHODS

A multidisciplinary team (health economics, emergency care, paramedicine, nursing) was formed, and a protocol registered on PROSPERO (CRD42023397840) and published open access. Eligible studies included experimental and analytical observational study designs of economic evaluation outcomes of patients requesting EMSs via an emergency telephone line ('000', '111', '999', '911' or equivalent) responded to by specialist community paramedics, compared to patients attended by usual care (i.e. standard paramedics). A three-stage systematic search was performed, including Peer Review of Electronic Search Strategies (PRESS) and Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). Two independent reviewers extracted and verified 51 unique characteristics from 11 studies, costs were inflated and converted, and outcomes were synthesised with comparisons by model, population, education and reliability of findings.

RESULTS

Eleven studies (n = 7136 intervention group) met the criteria. These included one cost-utility analysis (measuring both costs and consequences), four costing studies (measuring cost only) and six cohort studies (measuring consequences only). Quality was measured using Joanna Briggs Institute tools, and was moderate for ten studies, and low for one. Models included autonomous paramedics (six studies, n = 4132 intervention), physician oversight (three studies, n = 932 intervention) and/or special populations (five studies, n = 3004 intervention). Twenty-one outcomes were reported. Models unanimously reduced emergency department (ED) transportation by 14-78% (higher quality studies reduced emergency department transportation by 50-54%, n = 2639 intervention, p < 0.001), and costs were reduced by AU$338-1227 per attendance in four studies (n = 2962). One study performed an economic evaluation (n = 1549), finding both that the costs were reduced by AU$454 per attendance (although not statistically significant), and consequently that the intervention dominated with a > 95% chance of the model being cost effective at the UK incremental cost-effectiveness ratio threshold.

CONCLUSIONS

Community paramedic roles within EMSs reduced ED transportation by approximately half. However, the rate was highly variable owing to structural (such as local policies) and stochastic (such as the patient's medical condition) factors. As models unanimously reduced ED transportation-a major contributor to costs-they in turn lead to net healthcare system savings, provided there is sufficient demand to outweigh model costs and generate net savings. However, all models shift costs from EDs to EMSs, and therefore appropriate redistribution of benefits may be necessary to incentivise EMS investment. Policymakers for EMSs could consider negotiating with their health department, local ED or insurers to introduce a rebate for successful community paramedic non-ED-transportations. Following this, geographical areas with suitable non-emergency demand could be identified, and community paramedic models introduced and tested with a prospective economic evaluation or, where this is not feasible, with sufficient data collection to enable a post hoc analysis.

Out-of-hospital paramedic interactions with people living with dementia: a scoping review

BACKGROUND

Dementia encompasses neurodegenerative disorders that account for a global estimated healthcare expenditure of 1.3 trillion US dollars. In Australia, one in 12 people aged ≥65 has a diagnosis of dementia and it is the second leading cause of death. Paramedics play a crucial role in person-centred dementia care, particularly in the community. While consensus has been established on paramedicine's integration into interdisciplinary care teams, there remains a lack of clarity regarding the paramedic role in dementia care.

OBJECTIVE

This study aimed to examine and report paramedic interactions with people living with dementia in the out-of-hospital setting.

DESIGN AND SETTING

This was a scoping review study of paramedics and people living with dementia within the out-of-hospital setting.

METHODS

This study was guided by the Joanna Briggs Institute (JBI) scoping review framework. Databases were searched without date limits, up to 4 April 2023. These encompassed OVID Medline, CINAHL, Scopus, APA PsycInfo and OVID Embase. Articles were included if they were primary, peer-reviewed studies in English and reporting on paramedic-specific interactions with people living with dementia in the out-of-hospital setting. Data extraction was performed based on study setting, design, population and key findings.

RESULTS

Twenty-nine articles were included in the thematic analysis. Four themes emerged: need for training, patterns of attendances, patterns of documentation and the integrative potential of paramedicine. Paramedics reported feeling ill-equipped and unprepared in caring for patients living with dementia due to challenges in assessment and management of caregiver tensions. They were often called as a last resort due to poor service integration and a lack of alternative care pathways. Despite high conveyance rates, there was low incidence of paramedic interventions initiated. Underdocumentation of dementia and pain was found.

CONCLUSION

Emergency ambulance conveyance of people living with dementia is a surface reaction compounded by a lack of direction for paramedics in the provision of out-of-hospital care. There is a pressing need for establishment of research and educational priorities to improve paramedic training in dementia-specific skillsets.

Community paramedicine in dementia care

BACKGROUND

Novel hospital diversion strategies are needed to support a growing number of patients with dementia living in the community. One promising model is community paramedicine (CP), which deploys paramedics to the home, who consult with a physician to coordinate treatment and assess disposition. While evidence suggests CP can manage many patients without escalation to the emergency department (ED), no studies have evaluated optimal CP utilization for patients with dementia. Therefore, we compare the use and outcomes of CP for homebound patients with and without dementia.

METHODS

This retrospective cohort study examines 251 homebound patients receiving home-based primary care, who utilized a physician-led CP service between March 2017 and May 2022. Linked electronic health record data included patient demographics, clinical characteristics, and CP encounter details. Dementia status and CP outcomes, including rates of ED transport, over-transport (i.e., transported, but not hospitalized), and under-transport (i.e., not transported, but ED visit within 3 days), were determined via chart review. Using logistic regression, we modeled the association of dementia status with over- and under-transport, adjusting for age, sex, and chief complaint.

RESULTS

Fifty-three percent of CP patients had dementia. Their most common chief complaints were dyspnea (24.3%), altered mental status (17.9%), and generalized weakness (9.8%). We found no significant difference in ED transport rates by dementia status (25.4 vs. 22.8%, p = 0.54). Dementia diagnosis was associated with lower rates of over-transport (OR = 0.21, p = 0.03, CI [0.05, 0.85]) and comparable rates of under-transport (OR = 0.70, p = 0.47, CI [0.27, 1.83]) in adjusted models.

CONCLUSIONS

CP has effectively managed a diverse population of homebound patients with dementia cared for via home-based primary care. Future work should examine potential cost savings and use of CP in dementia care across geographic and healthcare settings.

Characteristics and Outcomes of Patients Referred to a General Practitioner by Victorian Paramedics

OBJECTIVE

Many patients who are attended by paramedics do not require conveyance to an emergency department (ED). Our study focuses on comparing the characteristics and outcomes of patients who were advised to follow up with a general practitioner (GP) by an attending paramedic with those of patients who were discharged at scene or transported to hospital.

METHODS

This was a retrospective data linkage cohort study of ambulance, ED, hospital admission, and death records for all adults attended by paramedics in Victoria, Australia between the 1st of January 2015 and 30th of June 2019. Patients were excluded if they presented in cardiac arrest, resided in a residential aged care facility, or were receiving palliative care services. Outcomes of interest included reattendance by ambulance, ED presentation; and, a high acuity outcome which we defined as a patient who (1) presented to ED and received an Australasian Triage Scale of category 1 (Resuscitation) or 2 (Emergency) AND was admitted to a ward OR (2) was admitted to an Intensive Care Unit, Coronary Care Unit or Catheter laboratory (regardless of triage category) OR (3) died. Outcomes of interest were considered within 48-h of initial EMS attendance.

RESULTS

A total of 1,777,950 cases were included in the study of which 3.1% were referred to a GP, 9.0% were discharged at scene without a follow-up recommendation, and 87.9% were transported to hospital. Patients referred to a GP were more likely than those discharged at scene to subsequently present to an ED within 48 h of their attendance (5.3% vs 3.8%). However, GP referral was not associated with any change to high acuity outcome (0.3% vs 0.2%) or ambulance reattendance (6.0% vs 6.0%) compared to discharge at scene. The only factors that were associated with ambulance reattendance, ED presentation, and a high acuity outcome were male gender and elevated temperature.

CONCLUSIONS

Despite increasing low and medium-acuity casework in this EMS system, paramedic referral to a GP is not common practice. Referring a patient to a GP did not reduce the likelihood of patients experiencing a high acuity outcome or recalling an ambulance within 48 h, suggesting opportunity exists to refine paramedic to GP referral practices.

Implementing community paramedicine: A known player in a new role. A narrative review

BACKGROUND

Community Paramedicine is a model of care which is effective and accepted by health professionals and the community. Community paramedicine delivers low acuity primary care to disadvantaged communities and addresses service gaps. We aimed to identify successful implementation of community paramedicine models and signalled opportunities and challenges.

METHODS

A narrative review was conducted. We identified 14 literature reviews from four databases EMBASE, CINAHL, PubMed, Cochrane. The results from the thematic analysis were structured along the quadruple aim for healthcare redesign framework.

RESULTS

The reviews supported acceptability of the model. Patients are satisfied and there is evidence of cost reduction. Long term evidence of the positive effects of community paramedicine on patient, community health and the health system are lacking. Equally, there is unfamiliarity about the role and how it is part of an integrated health model.

CONCLUSIONS

Community paramedicine could alleviate current stresses in the healthcare system and uses an available workforce of registered paramedics. To facilitate integration, we need more evidence on long-term effects for patients and the system. In addition, the unfamiliarity with the model needs to be addressed to enhance the uptake of the model.

'It breaks a narrative of paramedics, that we're lifesavers': A qualitative study of health professionals', bereaved family members' and carers' perceptions and experiences of palliative paramedicine

BACKGROUND

Paramedic practice is diversifying to accommodate evolving global health trends, including community paramedicine models and growing expertise in palliative and end-of-life care. However, despite palliative care specific clinical practice guidelines and existing training, paramedics still lack the skills, confidence and clinical support to provide this type of care.

AIM

To elicit paramedics', palliative care doctors and nurses', general practitioners', residential aged care nurses' and bereaved families and carers' experiences, perspectives, and attitudes on the role, barriers and enablers of paramedics delivering palliative and end-of-life care in community-based settings.

DESIGN

A qualitative study employing reflexive thematic analysis of data collected from semi-structured online interviews was utilised.

SETTING/PARTICIPANTS

A purposive sample of 50 stakeholders from all Australian jurisdictions participated.

RESULTS

Five themes were identified: positioning the paramedic (a dichotomy between the life saver and community responder); creating an identity (the trusted clinician in a crisis), fear and threat (feeling afraid of caring for the dying), permission to care (seeking consent to take a palliative approach) and the harsh reality (navigating the role in a limiting and siloed environment).

CONCLUSION

Paramedics were perceived to have a revered public identity, shaped by their ability to fix a crisis. However, paramedics and other health professionals also expressed fear and vulnerability when taking a palliative approach to care. Paramedics may require consent to move beyond a culture of curative care, yet all participant groups recognised their important adjunct role to support community-based palliative care.

Mobile Integrated Health Care Roles of US EMS Clinicians: A Descriptive Cross-Sectional Study

OBJECTIVE

Mobile integrated health care (MIH) leverages emergency medical services (EMS) clinicians to perform local health care functions. Little is known about the individual EMS clinicians working in this role. We sought to describe the prevalence, demographics, and training of EMS clinicians providing MIH in the United States (US).

METHODS

This is a cross-sectional study of US-based, nationally certified civilian EMS clinicians who completed the National Registry of Emergency Medical Technicians (NREMT) recertification application during the 2021-2022 cycle and completed the voluntary workforce survey. Workforce survey respondents self-identified their job roles within EMS, including MIH. If an MIH role was selected, additional questions clarified the primary role in EMS, type of MIH provided, and hours of MIH training received. We merged the workforce survey responses with the individual's NREMT recertification demographic profile. The prevalence of EMS clinicians with MIH roles and data on demographics, clinical care provided, and MIH training were calculated using descriptive statistics, including proportions with associated binomial 95% confidence intervals (CI).

RESULTS

Of 38,960 survey responses, 33,335 met inclusion criteria and 490 (1.5%; 95%CI 1.3-1.6%) EMS clinicians indicated MIH roles. Of these, 62.0% (95%CI 57.7-66.3%) provided MIH as their primary EMS role. EMS clinicians with MIH roles were present in all 50 states and certification levels included emergency medical technician (EMT) (42.8%; 95%CI 38.5-47.2%), advanced emergency medical technician (AEMT) (3.5%; 95%CI 1.9-5.1%), and paramedic (53.7%; 95%CI 49.3-58.1%). Over one-third (38.6%; 95%CI 34.3-42.9%) of EMS clinicians with MIH roles received bachelor's degrees or above, and 48.4% (95%CI 43.9%-52.8%) had been in their MIH roles for less than 3 years. Nearly half (45.6%; 95%CI 39.8-51.6%) of all EMS clinicians with primary MIH roles received less than 50 hours (h) of MIH training; only one-third (30.0%; 95%CI 24.7-35.6%) received more than 100 h of training.

CONCLUSION

Few nationally certified US EMS clinicians perform MIH roles. Only half of MIH roles were performed by paramedics; EMT and AEMT clinicians performed a substantial proportion of MIH roles. The observed variability in certification and training suggest heterogeneity in preparation and performance of MIH roles among US EMS clinicians.

Paramedic supportive discharge programmes to improve health system efficiency and patient outcomes: a scoping review protocol

INTRODUCTION

Discharging older adults with frailty home from the emergency department (ED) poses unique challenges due to multiple interacting physical and social problems. Paramedic supportive discharge services help overcome these challenges by adding in-home assessment and/or interventions. Our objective is to describe existing paramedic programmes designed to support discharge from the ED or hospital to avoid unnecessary hospital admissions. A comprehensive description of paramedic supportive discharge services will be conducted by mapping the literature to describe: (1) why such programmes are needed; (2) who is being targeted, making referrals and delivering the services and (3) what assessments and interventions are offered.

METHODS AND ANALYSIS

We will include studies that focus on expanded paramedic roles (community paramedicine) and extended scope postdischarge from the ED or hospital. All study designs will be included with no limit by language. We will include peer-reviewed articles and preprints and a targeted search of grey literature from January 2000 to June 2022. The proposed scoping review will be conducted in accordance with the Joanna Briggs Institute methodology. We will use a search strategy designed by a health science librarian to search MEDLINE All (Ovid), CINAHL Full Text (EBSCO), Embase (Elsevier) and Scopus (Elsevier) for eligible studies from 2000 to present. Two independent reviewers will conduct screening and full-text review. Data extraction will be conducted by one reviewer and verified by another. We will report our findings descriptively by charting trends in the research.

ETHICS AND DISSEMINATION

Research ethics review is not required as this is a scoping review comprised published studies. The results of this research will be published in a manuscript and presented at national and international geriatric and emergency medicine conferences. This research will inform future implementation studies on community paramedic supportive discharge services.
