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

In recent times we have seen ambulance services in the UK move away from being a component of secondary care towards the establishment of much firmer links within the primary care setting. Within this framework, the role of the paramedic has also evolved, moving away from its focus on basic first aid and patient transportation, to encompass higher levels of patient care and transform the prognoses of patients suffering from a wide range of trauma and medical conditions.
If ambulance services in UK are to continue to develop and build upon their contribution to the modern National Health Service (NHS), it has been widely acknowledged that they cannot meet this challenge by simply providing more of the same services they provide at present.1 The purpose of this review therefore was to examine the current evidence base in emergency medicine, both to inform the content of a third year degree option for the current Paramedic Diploma at Sheffield Hallam University, and to guide the development of a contemporary research agenda for paramedic practice.
DEFINING THE POLICY CONTEXT
The development of UK emergency services has today moved away from the evaluation of “unnecessary” accident and emergency (A&E) attendances towards the planning and provision of primary care services which are more responsive to consumer needs.2 Consequently, the Department of Health3 has summarised the future focus for the development of ambulance services as follows:
To raise public awareness of what constitutes appropriate use of emergency services.
To develop and evaluate alternative “emergency” call handling services.
To review current 999 call prioritisation categories and the management of 999 calls within the Service.
To create and evaluate alternatives to the routine transport of patients to hospital A&E departments.
Service initiatives in response to policy
Several service initiatives aimed at meeting the challenges listed above are currently under review and evaluation across the UK.
The changing face of paramedic practice
In 2000, the Ambulance Service Association4 sanctioned the development of “a new echelon of generic health care worker”, in the form of the Practitioner in Emergency Care. The impetus towards a broader education for paramedics began in 19983 with the adoption of graduate entry to the profession via university undergraduate programmes and moves to establish service links with local universities. Following a national service evaluation by the Commission for Health Improvement, the NHS Modernisation Agency Improvement Partnership for Ambulance Services was launched in September 2003. Its aim was to integrate the ambulance services into the total healthcare system, by developing understanding, building recognition, and releasing staff potential. Having highlighted the need to introduce new ways of working in conjunction with major redesign of the paramedic role, a series of new “practitioner” posts were conceived. These included:
Community paramedics (based in general practice (GP) surgeries)
Critical care paramedics (based in hospital intensive care facilities)
Intermediate care paramedics (managing all aspects of the service)
Treat and refer paramedics (based in minor injury units/walk-in centres).
The government’s Changing Workforce Programme subsequently launched the paramedic Accelerated Development Programme and the paramedic Practitioner Trial, both of which focused upon the evaluation of a wide range of “emergency care practitioners” in several pilot sites across the UK (box 1).

NHS Direct (1998) and Care Direct (2001) services have been introduced as an alternative to the GP or “999” call, and have been shown to provide high levels of customer satisfaction, although access appears to be limited to certain more affluent and articulate groups within the overall population.5 Indeed, their critics have voiced concerns that such facilities have simply created an additional demand for emergency services, rather than rationalising the pre-existing workload.6
Minor injury units and walk-in centres
To provide relief for overcrowded hospital A&E departments, minor injury units, walk-in centres, and primary care centres have been gradually phased in across the UK since the mid-1990s. Studies continue to demonstrate the effectiveness of such services in terms of reduced waiting times and subsequent A&E attendances,7,8 although to date, their cost effectiveness has not been rigorously assessed.9 There remains, however, a wide variation in service provision, which may have given rise to some level of confusion about service availability, in particular among certain minority populations, specially where English is not the first language.9
Intermediate care services
The need to put in place some form of “intermediate” care for older people and those with mental illness gained momentum following a report from the Audit Commission10 and the findings of the National Bed Enquiry.11 Guidance by the Department of Health12 placed emphasis on the development of a “seamless continuum of services”, providing rapid assessment and diagnosis, the avoidance of unnecessary hospital admissions and the facilitation of earlier, supported discharge in the home environment. Although there is insufficient evidence to draw definitive conclusions, it does appear that the introduction of additional services or service elements into intermediate care appears to be causing even more complexity and uncertainty, thereby inhibiting, rather than promoting, holistic service provision for these particular client groups.13
GP out of hours services
Recent changes to the National Out of Hours Contract (April 2004) will mean that fewer GPs will now opt to provide out of hours services,14,15 which must impact on the future demand for alternative emergency care services.
To clarify the future demands on the paramedic in the primary care setting, and to identify the basic skills, training, and professional capacity which paramedics of the future will undoubtedly require, the evidence concerned with paramedic practice was explored by an indepth search of literature published between January 1995 and April 2004. Data sources accessed are shown in box 2. The search terms (box 3) used were wide and varied because of the lack of publications evidenced in this field of study.

To complement the literature search and further develop the knowledge base, a series of informal discussions with staff of the South Yorkshire Ambulance Service and Sheffield Hallam University, the Workforce Development Team (NHS Modernisation Agency), and researchers currently active in the field of emergency care were also undertaken.
The nature of the evidence base
Despite widespread acknowledgement of the value of the role of the paramedic in managing prehospital crises, this review found the body of high quality evidence with which to validate key aspects of paramedic practice to be minimal. The evidence base is currently growing, gaining increased impetus with the establishment of the International Pre-Hospital Network within the Cochrane Collaboration and the introduction of NHS clinical governance, clinical audit, and risk management initiatives. However, the number of randomised controlled trials at present described in the literature is diminutive, with few evaluating outcomes for paramedic interventions effectively.16,17
Given the paucity of published evidence, this review comprises an overview of key articles and literature reviews by well recognised researchers in the field of emergency care. These articles were systematically collated and contextualised in combination with government documents and contemporary commentaries.
Key findings from the evidence
The available literature was collected and appraised and the findings explored working with the concept of the patient journey.
The telephone call
Across the UK the total number of 999 calls continues to rise annually, while the total number of incidents attended by ambulance crews is also rising.18,19 However, available evidence reveals that the majority of emergency calls do not require paramedic skills,20 hence the next logical step has been to focus upon the interception, assessment, and prioritisation of calls, in conjunction with the provision of more appropriate responses, which better recognise patient needs. To date, systematic reviews of research into the ability of ambulance service staff to triage patients by telephone to alternative models of care have repeatedly acknowledged weak research methodologies and hence, inconclusive findings.21 There are, however, several well validated studies in this field which focus on nurse led triage and management of non-urgent calls in a central control room, and these have concluded that telephone advice is safe, acceptable to callers, and cost effective to service providers.22
There remains very little high quality published evidence to quantify the effect of call prioritisation in terms of patient outcomes, and attempts at the analysis of existing literature have been hindered by the wide variety and type of telephone triage criteria and outcome measures utilised. It has also been suggested that the initiation of new research in this field has temporarily stalled, due to the imposition of National Response Time Standards across the UK ambulance services. These targets appear to have led the Service to focus more on the “manipulation and improvement” of performance data per se, rather than the initiation of improvements in patient handling and subsequent patient care.23 The lack of contemporary evidence to link such targets with improvements in patient survival rates has now been acknowledged however,24 and the search for more appropriate performance indicators continues.
At the incident scene
Around the globe, the validating evidence for many elements of prehospital, on-scene triage by paramedics remains in short supply, and the majority of current practice is therefore founded upon anecdotal evidence and expert opinion.3 Many researchers have described the sheer breadth of possible on-scene diagnoses as being beyond the grasp of current paramedic practice,25 and have particularly highlighted the consistent problems with the recognition, diagnosis, and management of “occult” (that is, hidden) conditions, minor illnesses, and trauma.26
The development and implementation of universal clinical guidelines within the ambulance service is currently a priority, however, research in this field has been described as “pseudo scientific”, exhibiting little internal validity and demonstrating huge variation in outcomes.27 Many studies have found the use of clinical guidelines to be “impractical” and have repeatedly found guidelines to be misapplied in practice settings, with a large proportion of conditions, or severity of conditions, being misdiagnosed.28 Indeed, it has been argued by some that guidelines have proved counterproductive, causing the paramedic role to evolve as a product of what doctors have made it, rather than fostering the growth of the autonomous practitioner, capable of questioning what should reasonably be done, and where.29
A small number of high quality studies, however, have shown paramedics to be capable of the successful triage of certain patients on-scene. For example, paramedics have been shown to perform well in identification of a cohort of patients with definite cardiac infarction30 and in the redirection of non-urgent callers to alternative destinations to A&E.31 Despite these findings, many researchers feel that the overriding unacceptability of under-triage at the incident scene (and, to a lesser extent, the undesirably high costs of over-triage),32 which is present within today’s “risk managed” service means that future research efforts would be more effective if they focus instead upon identifying and eliminating the primary barriers to healthcare access which are associated with inappropriate calls to the 999 service.
The paramedic practitioner
There is a developing body of research into the piloting of the paramedic practitioner role in a wide range of settings, but this proved difficult to collect and appraise with rigour, due to its ongoing nature and lack of formal publication. Nevertheless, results from “work in progress” appear promising.
The East Anglian Ambulance Service Trust is currently evaluating the community paramedic role, and a published review of its findings to date has shown a dramatic reduction in A&E admissions coupled with improvements in 999 response times.33 The South Yorkshire Ambulance Service has also invested in the training of community paramedics, who are employed in a trial of an intermediate care support scheme. Early indications are promising and show that over half of older patients with minor injuries are now being treated in their own homes.34 Trials of the emergency care practitioner role by both the London Ambulance Service and the West Country Ambulance Service have revealed patients to be receiving “more appropriate care more rapidly”.
Maintaining the paramedic workforce
Job satisfaction and personal wellbeing among paramedics are undoubtedly important issues, which must come to the fore. Perceptions of new roles and ongoing changes in service delivery are varied, and discussions within Workforce Development Team focus groups revealed that not all practitioners regard such innovation as the “exciting opportunity” portrayed in the media.
National Response Times have meant that the majority of ambulance services now use continuous vehicle mobilisation between caller “hot spots”, with staff no longer able to spend time between calls on the station, relaxing and socialising with colleagues. As a consequence of this new way of working, levels of stress related illness are increasing within the service,35 while concerns surrounding the lack of scope for post-trauma counselling and debriefing continue to grow. Development of the clinical supervisor’s role may provide one possible support mechanism.
Increases in the incidence of postural, musculoskeletal pain from prolonged sitting in a vehicle on stand-by have also been identified as recurrent problematic areas within the field of occupational health. Although published research in this field remains minimal, the South Yorkshire Ambulance Service is among a small number of providers involved in the evaluation of a “fast track” physiotherapy service for employees with persistent back pain.36
DISCUSSION AND RECOMMENDATIONS
If ambulance services are to move towards becoming part of a fully integrated care delivery system with access to numerous service “portals”, partnership is the key to the future, and a great deal of work is ongoing to respond to this challenge across the UK.
A large proportion of the published research has been aimed at reducing inappropriate patient transport and has targeted improvements in on-scene triage by the implementation of clinical guidelines. However, a combination of National Service Response Times and the medicolegal environment mean that, at present, such interventions have a limited potential for savings, both in terms of service deployment and relative costs. Future research effort, therefore, might prove more constructive if it focused upon raising the profile of new service options in both public and training arenas, while also further exploring the seminal inequalities in service access that still remain among vulnerable minority populations.
The key to the future provision of prehospital care is dependent on improvements in call prioritisation and triage systems, and must lie in working in parallel with other healthcare providers. There is an underlying impetus for a single NHS call prioritisation system, based upon the concept of a centralised “response generator”, intercepting 999 calls, GP out of hours calls and NHS Direct/Care Direct calls and determining an appropriate, integrated service response. If ambulance services are to continue to concentrate upon the delivery of emergency care to patients’ at most immediate life threatening risk, they must develop specialist resources to target such cases, whereas callers who do not require a specialist response should be more appropriately redirected to alternative points of health service access.
In the immediate future therefore there will undoubtedly be a need for paramedic practitioners, possibly based within a primary care setting, who are capable of the accurate recognition of a wide range of both adult and paediatric conditions, carrying out rapid on-scene assessments, instituting advanced treatments in line with evidence based guidelines, and fast-tracking patients in a stable condition to the nearest, most appropriate, destination.
Hopefully this review has served not only to clarify the future demands which confront the emergency services in the primary care setting, but has also identified the core skills, training, and professional development which paramedics of the future will require. However, the opportunities for paramedic development vary considerably across the UK, possibly as a corollary of the lack of valid research evidence with which to support their skills in practice. Nevertheless there is little doubt that the ambulance services of the future must accommodate certain key paramedics, capable of operating as an independent practitioners and trained to a much higher level in patient assessment and decision making skills. In their turn, complementary health service staff must be prepared to both accept and respect their newfound autonomy.
National links between paramedic educational programmes remain underdeveloped, and some continue to target the development of managerial skills rather than clinical competence, thus failing to provide a sound basis for uniform career foundation. The lack of involvement of paramedics in service changes also does not bode well for the future. To reassert their rightful place in the provision of prehospital care, practitioners must be educated and encouraged to take a far broader, all encompassing view of their practice and its effect upon patient outcomes.
The UK ambulance service today remains under increasing and unremitting pressure, with both the number of incidents attended and the predicted demand for patient journeys continuing to rise. Within this setting, the service is compelled to move away from being a relatively uncomplicated patient transport system towards becoming part of a fully integrated, national healthcare service, to “do things differently”, and thereby facilitate a fully coordinated and holistic approach to patient handling in the community. It becomes clear that within this framework the paramedic of the future must be able to effectively diagnose a far wider range of conditions, institute treatment according to national evidence based guidelines, reflect upon and critically evaluate the effectiveness of care, determine when and if specific interventions should be used, and provide optimum care solutions which are unique and specifically tailored to each patient.
Holistic ways of working which take a far wider approach to service provision are the long term goal therefore and, as such, must impact upon the future training of the paramedic. Paramedic training must move its focus away from the acquisition of clinical skills (no matter how wide ranging), towards fostering the ability to think and practise autonomously. In the short term, paramedics must be taught to appropriately diagnose and manage a wider range of patients, particularly those who present with occult (hidden) conditions, minor illnesses, and minor trauma. In the longer term, and more importantly however, they must learn to work together to take ownership of the basic philosophies of their practice, which are solidly grounded in methodologically valid and reliable research, and therefore truly “evidence based”.
