Introduction
Paramedic practice is continuously evolving and innovating, expanding in both acute and non-acute settings as paramedicine continues to establish itself as an essential part of an integrated healthcare model [
1]. There is ample opportunity to explore current paramedicine systems to guide future direction for progress and innovation. One example of a more recent innovation in paramedicine includes paramedics in expanded roles, such as extended care and community paramedics [
2]. Community paramedicine has evolved from initiatives to reduce the burden on emergency health services to programs that “
uses paramedics to provide immediate or scheduled primary, urgent, and/or specialised healthcare to vulnerable populations by focusing on improving equity in healthcare access across the continuum of care” [
3,
4].
A person receiving healthcare is always immersed in a mix of health and social contexts [
5,
6]. Moreover, everyone is born into and exists within a health and social continuum [
5]. This dynamic continuum means that increases in health incidences may be related to unmet social needs; while those with social privileges and adequate support may experience less frequent or severe health incidences [
5,
6,
7]. Individual and population health is impacted by broad factors, with complex implications dependent on social determinants and economic environments, physical environments, and individuals’ behaviours and inherent characteristics throughout a lifetime [
5]. The concept of the health and social continuum illustrates that health and social factors are inextricably connected [
5,
6].
The social determinants of health (SDH) describe specific social and economic factors that determine health status [
5]. These relate to an individual’s position in society and expand beyond individual characteristics to include unearned advantages (i.e., privileges) and unearned disadvantages (i.e., discrimination, structural marginalisation). Experiences of discrimination, racism and trauma, both historical and contemporary, are important social determinants of health that disproportionately impact groups such as Indigenous Peoples, gender and/or sexually diverse individuals, and racialized populations [
5,
7,
8,
9].
This means that when paramedics respond to address an individual’s health needs, they also regularly encounter social aspects requiring assessment and care. Community paramedics are uniquely positioned to encounter individuals needing care in their homes and communities, and therefore have access to important information about a person’s environmental, social, and cultural contexts that other health professionals are not directly privy to. The primary health concern may be why paramedics are called to deliver health care - but the health problem may in fact be an outcome of unmet social needs.
Given the historical focus of community paramedicine programs towards meeting healthcare needs, we focused this scoping review on community needs along a health and social continuum. We centred our focus on social needs within the determinants of health, such as poverty, social isolation, culture, and access to health and social services.
Objective
The objective of this scoping review was to systematically scope the extent of published peer reviewed, and grey literature to identify how community paramedicine supports community needs along a health and social continuum, with a key focus on research implications and how this may inform future practice and health service development [
10,
11]. We sought to answer the following research questions formulated using the population, concept, context (PCC) framework: (1) How does community paramedicine support social needs along a health and social continuum?; (2) What does the literature highlight regarding innovation and opportunities to better meet social needs?; and (3) What gaps exist in the literature that may inspire future research to address social needs? Acknowledging that relevant grey literature on the provision of community paramedicine exists, we elected to conduct a scoping review to achieve the study objectives [
11]. We narrowed the research focus to community paramedicine due to the increasing ways these programs are expanding services within communities, including program development targeting specific structurally marginalised populations and community needs [
4].
Conceptual Framework
Prioritising equity and accountability of the profession, Tavares et al., identified paramedic roles at the individual practitioner-level [
12], and further outlined principles and enabling factors to lead the progression of the paramedicine profession at the system-level [
13]. While all concepts within these complementary studies intersect, the systems level principles of
health care along a health and social continuum and
social responsiveness, and the enactment by individual practitioners in their role as
health and social advocates provides the conceptual lens from which we approached this work [
12].
Language
We recognize the importance and evolution of language in accurately describing populations and their intersectional positions in society [
14,
15]. Therefore, we endeavour to use language within this manuscript that identifies the structural and systemic factors determining societal hierarchies and their inherent power imbalances. We will use language such as oppressed, marginalised, and under-resourced to reflect the ways dominant groups determine socioeconomic policies and constructs that oppress some, while privileging others. This acknowledges that populations are not inherently vulnerable, rather vulnerability is an outcome of systemic and structural discrimination, being under-resourced and therefore, marginalised [
15]. All people, communities and population groups are equal in value and worth. We use this intentional language to point to the systems of oppression resulting in marginalised outcomes rather than misidentifying certain populations themselves as possessing deficit(s).
Methods
We conducted the scoping review in accordance with JBI Scoping Review Guidance [
16]. We registered the protocol with the Open Science Framework (
https://osf.io/2d9j6/) in April
2023. We reported our process and findings according to the PRISMA Extension for Scoping Reviews [
17]. We conducted a preliminary search of Google Scholar, MEDLINE, and JBI Evidence Synthesis to prevent duplication of effort and we did not identify any current or in-progress systematic or scoping reviews on the topic.
Identification of Relevant Studies
The search strategy aimed to locate both peer-reviewed and non-peer reviewed studies. Only articles published at the time this review was completed were included in this study. We conducted an initial limited search of Google Scholar and MEDLINE to inform our search strategy. The text words contained in the titles and abstracts of relevant articles (e.g., terms for community paramedicine, health and social continuum, and social needs), and the index terms used to describe the articles were used to further inform the search strategy. The search strategy, including all identified keywords and index terms, was further adapted for each database and/or information source (see Online Resource 1).
We searched CINAHL, MEDLINE, and EMBASE in March and April 2023. Grey literature searches were guided by the CADTH Grey Matters toolkit, limited to primary sources identified through the International Roundtable on Community Paramedicine website (
http://ircp.info), Google Scholar and Google [
18]. Any reports identified through grey literature searches that were previously identified through database searches were excluded to avoid duplication. We also performed citation searching of the final included studies identified from databases using ‘citationchaser’ software [
19].
Study Selection
Studies of any design (including editorials and commentaries) as well as grey literature were selected if they discussed how community paramedicine supports community needs along a health and social continuum and were published in English. Articles were excluded if their primary focus was outside the context of community paramedicine, if they did not address community health and social needs, if they described an economic or geospatial analysis or a study protocol, or if they were available as abstract only (e.g., conference abstracts).
The review process consisted of title and abstract screening followed by full-text review. A title/abstract screening form was developed by the primary author (TL) informed by the JBI Scoping Review Guidance, using Covidence (Veritas Health, Melbourne, Australia) and reviewed by both co-authors (JB and AB) [
16]. The screening criteria were tested on a sample of abstracts prior to beginning the abstract review to ensure that they were sensitive enough to capture any articles that may relate to the review question. Two of the authors (TL and JB) independently screened titles and abstracts. Conflicts were resolved by AB and criteria were refined until agreement was reached. In the second step, two of the authors (TL and JB) independently assessed the full texts of screened articles in duplicate to determine if they met the inclusion/exclusion criteria. Conflicts were resolved by AB.
Data Charting
Data were extracted by one reviewer (TL), using a data extraction form created by the primary researcher (TL), informed by the JBI Scoping Review Guidance (see Online Resource 2) [
16]. All extracted data were checked for accuracy by one author (AB) who did not partake in the data extraction. Data extracted included article title, author name and year of publication, country of study, study design, study aim/objective, program setting and type, referral source, health and social needs assessment and education, key findings, discussion, conclusions about community paramedicine supporting health and social needs, and inductive categorisation. We exported the extracted data from Covidence into Excel 365 (Microsoft, Redmond, WA) for collation, analysis, and synthesis.
Collating, Summarising, and Reporting Results
We used the extracted data to report on the included articles’ findings. Descriptive statistics were used to report the occurrence of concepts, characteristics, and populations. We conducted a descriptive qualitative content analysis of study characteristics to explore, summarise, and report qualitative data [
20]. We performed this via basic-level inductive coding. This was performed independently by two authors (TL and AB) in Covidence, and any discrepancies were resolved via discussion. Codes were combined into organising categories as appropriate to facilitate summary and discussion. Papers were categorised based on their principal issue into five domains [
21]. We report both measures and descriptions to quantify and explore the characteristics of the literature.
Trustworthiness and Rigour
In addition to the steps outlined to ensure rigour in the scoping review screening and extraction process, we aimed to ensure trustworthiness in our analysis of the included studies [
22]. Data were extracted directly from Covidence, reducing the chance of transcription errors. We aimed to ensure credibility and confirmability by performing multiple in-depth searches of the literature and using an inductive approach to our descriptive qualitative content analysis. This allowed the literature to guide the creation of categories [
21]. We aimed to ensure transferability by exploring literature on a global scale, with no time limitations, thereby accounting for a wide variety of contexts. Dependability was ensured through protocol publication, a clear audit trail, and multiple author review of data throughout the study. We did not evaluate included studies for quality as per the JBI Scoping Review methodology [
16].

Discussion
This scoping review aimed to explore how community paramedicine supports community needs along a health and social continuum and to identify gaps and opportunities for future research. We identified 43 articles from four countries published between 2003 and 2023. Our findings demonstrate that community paramedicine has evolved and is continuing to innovate to support community needs through a variety of program models across various settings.
Community paramedicine continues to expand in the United Kingdom, the Republic of Ireland, Finland, Australia, New Zealand, Canada and the USA [
3,
4,
56,
58,
60,
63]. This model of care is rapidly evolving in response to ageing populations and to address gaps in primary care [
3,
59,
60]. Expansion of the paramedicine specialty has been largely motivated by health system utilisation measures, where emergency department avoidance and readmission is a key driver [
3,
56,
58,
60]. Recognizing the benefits to optimising service utilisation, attention should be called to including additional indicators such as healthcare experiences, outcomes, and improved social support. Where paramedic practice has traditionally taken a reactive and pathogenic approach to healthcare delivery, Cockrell advances the benefit of applying a salutogenic approach where care focuses on supporting health and well-being rather than factors that cause disease (salutogenesis) [
29]. Programs are engaging with this concept in increasingly proactive ways, such as recognizing and targeting social needs as key determinants of health [
1,
57,
64]. Community paramedicine has potential to enable values-based care models by integrating services with primary health and social services to reduce barriers for structurally marginalised populations [
45,
50,
65,
66].
Advances in technology enable innovations in healthcare to bridge access to service gaps, including telehealth, remote patient monitoring and virtual care, particularly in response to the COVID-19 pandemic [
28,
37,
56]. Despite this, the evidence fails to provide guidance on optimal approaches to leveraging technologies in coordinating and supporting care. Recommendations exist to develop standards for virtual care, social media use, and enhancing cross-jurisdiction communications to rapidly coordinate during crisis response [
67,
68]. This will also require developing standards for data stewardship in program evaluation, quality improvement, and research [
69]. There is a need to engage health systems planners to determine the most appropriate responsibility for sustainably sourcing, maintaining and the ongoing education necessary to optimise technology in paramedic care.
There were benefits observed when paramedics integrated the extension of person-centred palliative approaches to care into the home, and thereby optimising quality of life along the trajectory of illness [
70]. Within an Indigenous community in the remote north of Canada, community paramedicine could address many health and social service gaps [
27,
71]. Authors cautioned against a one-size-fits-all approach and highlighted the need for programs to better address the needs of communities by including relevant program indicators [
3,
27,
34,
71]. A key recommendation across the literature was the need to meaningfully engage broader partners and communities early in program planning to understand how best to co-design and implement an integrated service model that addresses the specific needs of each community [
3,
27,
29,
34,
41,
54]. There were also cautions that focusing on increasing access to health and social services provided by the state-only risks further embedding settler colonialism in health and social equity efforts [
72]. This requires paramedicine leaders to critically examine whose voices and perspectives are included at decision-making tables and whose are not. This reinforces the necessity to further study and incorporate equitable practices for community and stakeholder engagement and apply learnings from others when assessing community need [
27,
41,
45].
The move towards tertiary education for community paramedicine specialisation in some jurisdictions provides greater opportunities for interprofessional learning to prepare paramedics as integrated members of the primary and greater healthcare team [
3,
4,
29,
63,
73]. While studies mentioned additional paramedic training on SDH, what this training entailed was unclear or implicit, and inconsistencies in this requirement across studies indicate opportunity to enhance this education to better prepare paramedics to respond to the complexities of care within the health and social continuum [
3,
73]. Educators and program developers should expand beyond paramedicine to examine what can be learned from other professions in addressing equity along a health and social continuum. Paramedicine will reciprocally benefit from partnering, mentorship and collaboration with broad health and social professionals [
66].
While some studies in this review targeted social needs, few programs appeared to examine the implications of intersectionality and structural competency on health and social inequities [
1,
54,
61]. This intentionality was applied in a study that examined women’s experiences participating in a community paramedic program, where participants reported an overall reduction in barriers to care that specifically prioritised women’s health needs [
35]. Evidence shows workforce diversity gaps have a direct effect on care and outcomes, revealing that practitioners employed in more homogeneous environments possess greater risk of providing inequitable care [
74,
75,
76,
77,
78]. Community paramedicine should lead responsibly by applying knowledge in the provision of intersectionality and structural competency to workforce recruitment strategies, practitioner education and systems-level planning [
9,
14,
15,
79,
80]. A core tenet of community paramedicine is cultivating trusting relationships, and while paramedics are generally perceived as trusted health professionals, there is an opportunity to examine how program planning and implementation can be optimised by recruiting practitioners who represent and reflect the cultures of the communities served [
41,
74,
81].
Finally, as evidenced by this review, community paramedicine is rapidly evolving to provide responsive and integrated healthcare to communities. However, as Ford-Jones cautions - paramedics face tensions between implementing beneficial practice in response to unmet social needs, and the need to influence policymakers within health and non-health professions [
54]. Paramedics must take appropriate action at the public policy level to develop evidence-informed, upstream solutions to address broader determinants of health in sustainable ways [
54,
82]. Training paramedics to address increasing mental health needs is not a viable option to address the intersectional and structural barriers that must be addressed via broader policy [
29,
40,
41,
54]. Acknowledging that political and socioeconomic factors are key determinants of health, there is a need for paramedicine broadly to determine roles in health and social advocacy to influence policy that commits to health equity and justice, for all [
12,
13,
72,
79,
80].
Future Directions
While our findings demonstrate that community paramedicine has evolved to support community health and social needs through a variety of program models across various settings, gaps exist for future research in community paramedicine. Guided by the principles of
patients and their communities first and
social responsiveness, it is paramount to ensure community paramedicine program design is needs-based [
13,
80]. It is important to determine key elements to inform a framework guiding community needs assessments. To address healthcare inequities that are a result of system-centred programming, those developing community paramedicine must commit to co-designing service models, specifically including perspectives from structurally marginalised groups [
27,
47,
83]. Considering an intersectional lens, paramedicine leaders will require guidance on how to engage in equitable stakeholder engagement, including amplifying voices of people receiving care and their caregivers. Community paramedicine leaders and strategists should seek to identify transferable strategies from outside paramedicine and health-adjacent professions and seek opportunities to integrate care to optimise initiatives addressing healthcare along a health and social continuum. These intersecting areas of study opportunities need to be thoroughly explored and strategies implemented in ongoing effort to eliminate health outcome gaps.
