Abstract
Objectives
Paramedics routinely make critical decisions about the most appropriate care to deliver in a complex system characterized by significant variation in patient case-mix, care pathways and linked service providers. There has been little research carried out in the ambulance service to identify areas of risk associated with decisions about patient care. The aim of this study was to explore systemic influences on decision making by paramedics relating to care transitions to identify potential risk factors.
Methods
An exploratory multi-method qualitative study was conducted in three English National Health Service (NHS) Ambulance Service Trusts, focusing on decision making by paramedic and specialist paramedic staff. Researchers observed 57 staff across 34 shifts. Ten staff completed digital diaries and three focus groups were conducted with 21 staff.
Results
Nine types of decision were identified, ranging from emergency department conveyance and specialist emergency pathways to non-conveyance. Seven overarching systemic influences and risk factors potentially influencing decision making were identified: demand; performance priorities; access to care options; risk tolerance; training and development; communication and feedback and resources.
Conclusions
Use of multiple methods provided a consistent picture of key systemic influences and potential risk factors. The study highlighted the increased complexity of paramedic decisions and multi-level system influences that may exacerbate risk. The findings have implications at the level of individual NHS Ambulance Service Trusts (e.g. ensuring an appropriately skilled workforce to manage diverse patient needs and reduce emergency department conveyance) and at the wider prehospital emergency care system level (e.g. ensuring access to appropriate patient care options as alternatives to the emergency department).
Introduction
The delivery of prehospital emergency care within the UK National Health Service (NHS) embodies challenges for risk management and patient safety. Reviews of relevant patient safety research have identified a limited range of studies in the prehospital emergency care setting1,2 and recommend further research to develop our understanding of threats to patient safety. 1 The need to understand what influences decisions about patient care and areas of potential risk has been identified as a priority for future research in prehospital urgent and emergency care. 3 A Canadian study exploring emergency medical and health providers’ perceptions of key issues in prehospital patient safety raised concerns about system influences on decision making, including the increased complexity of clinical decisions encountered and constraints on staff skills. 4 Both of these are pertinent issues in the UK context.
Paramedics routinely make critical decisions about patient care in a complex environment characterized by significant variation in patient case-mix, care pathways and linked service providers. Decisions at key transitions entail considering a range of options, including conveyance to hospital, either the Emergency Department (ED) or specialist centres (stroke, cardiac and trauma), referral to other services or discharge at scene. Where patients have critical or life-threatening conditions, transport to hospital is the most appropriate decision. 5 However, it is estimated that only around 10% of 999 patients have a life-threatening condition, prompting greater efforts in recent years to provide alternative care options appropriate to the majority of patients. 6 Not transporting patients to the ED requires paramedics to make clinical decisions in a system where ED has traditionally been the default option. Safety related concerns have been raised about non-conveyance decisions, for example, one study found high rates of subsequent emergency healthcare contacts and an increased risk of death and hospitalisation for older people left at home following a fall. 7 Although ambulance services have policies and protocols to guide staff in making appropriate decisions, in reality decisions not to convey patients to ED are often more complex than the scope of protocols and paramedics are reliant on their own professional judgment to interpret ambiguous situations. 8 Non-conveyance decisions often involve negotiation between paramedics and patients, highlighting non-clinical considerations and the issue of patient choice. 8 A study examining the complexity of decision making for assessment and referral of older people who have fallen identified a predominance of informal decision making. 9 The authors concluded that further research is needed to look at how new care pathways offering an alternative to the ED may influence decisions.
Ambulance services are making increasing use of specialist paramedic roles, including, emergency care practitioner (ECP), paramedic practitioner (PP), community paramedic (CP), and critical care paramedic (CCP), equipped with the enhanced knowledge and skills needed to make more complex decisions about patient care. The available evidence indicates that specialist roles have reduced conveyance to ED and increased discharge at scene, thus reducing the costs associated with ambulance journeys, ED attendances and hospital admissions.10,11 However, one of these reviews also concluded that there is a lack of rigorous evidence on the appropriateness of decisions and the safety of patients. 11 The need for a better understanding of influences on the safety of paramedic decision making and potential risk factors (threats) is particularly important in the context of plans to develop emergency ambulances into mobile urgent treatment services capable of dealing with more people at scene, 5 to ensure that such developments do not increase the risk for patients. The aim of our study was to explore system-wide influences on decision making by paramedics, focussing on care transitions and potential risk factors. This encompasses multi-level system influences at the macro-level (prehospital emergency care system); meso-level (Ambulance Service Trust) and the micro-level (local areas/stations).
Methods
Types of transition decisions encountered by paramedics.
ED: emergency department; STEMI: ST-elevation myocardial infarction; GP: general practitioner; MH: mental health.
Data collection
Details of study sites and participants.
Ints: interviews; Obs: Phase 2 observations; DD: digital diaries; FG: focus groups; ECP: emergency care practitioner; CCP: critical care paramedic; PP: paramedic practitioner; CP: community paramedic.
Table 1 shows the participants’ roles in the Phase 1 interviews (Ints), and Phase 2 observations (Obs), digital diaries (DD) and focus groups (FG). On dual crew ambulances, the second crew member was often a less highly skilled member of staff (e.g. emergency care assistant or technician). Phase 2 participants had ambulance service experience ranging from less than one year to 20 years. Staff observed included solo rapid response (n = 11), dual crew members (n = 23) and specialist paramedics (ECP, PP, CCP, CP).
Data analysis
Qualitative data analysis involved two researchers and regular review with the project team. The initial analysis was conducted by site, consistent with the sequential order of data collection. ATLAS.ti 7 qualitative data analysis software 16 was used for the analysis. Data transcripts from the Phase 1 interviews were thematically analysed using a constant comparison approach. The themes identified were subsequently explored in the focus groups. Documents identified as relevant during Phase 1 were reviewed to develop an understanding of the context in which the paramedics operate. Documentation identified during Phase 2 enhanced our understanding.
Analysis of data transcripts from Phase 2 (observations, interviews, diaries) involved an iterative process of data coding and categorisation. This entailed checks of between-coder reliability and repeated comparison within and then across the Trusts, to identify similarities and differences. The initial analysis identified types of transition decisions, whereby each decision was assigned to only one category. This was followed by the coding of influences on decisions and patient safety. Focus group data transcripts were thematically analysed using a constant comparison approach.
Subsequent analysis combined the data for each method across the three sites to examine similarities and differences. Vincent et al.’s Human Factors framework 17 was used to classify system influences across all Phase 2 methods. A further synthesis of the data was conducted to generate a smaller number of overarching themes representing key influences on transition decisions and potential risk factors.
Ethics
The study received ethics approval from the University of Sheffield Research Ethics Committee (ScHARR REC REF 0530/KW) on the basis that no patient identifying information would be collected and the researchers would not elicit any information from patients.
Results
The findings revealed the complexity of transition decisions and system influences potentially impacting on patient safety. Nine typologies of paramedic transition decisions were identified (Box 1) and reflect the array of decision scenarios routinely encountered by paramedics.
Transition decisions range from relatively clear-cut emergencies, including protocol-driven decisions for conditions such as trauma or ST-elevation myocardial infarction (STEMI), to more complex cases where the patients’ social circumstances and co-morbidities need consideration. The latter type of decision created most uncertainty and risk for both patients and paramedics (i.e. professional vulnerability), since certainty about handover of clinical responsibility for patients to an appropriate health or social care provider was perceived as critical to good and safe care. Although some decisions appeared less complex, for example, where conveyance to hospital was evidently appropriate, few decisions could be classed as completely unequivocal.
System influences on decisions
Seven overarching system influences on decision making, identified as potential risk factors, are outlined below. The first three system influences encompass both macro-level and meso-level issues (demand; performance regime; care options); the following three encompass both meso-level and micro-level issues (risk aversion; training; communication), and the final influence (resources), which has system-wide relevance, focusses predominantly on the meso-level and micro-level.
Increasing demand
Increased demand for ambulance service care has impacted on the scope of clinical decision making by paramedics as the profile of calls has shifted from primarily emergency care decisions to now dealing with a wider range of primary care and psychosocial decisions. Such decisions, where non-conveyance was an option, are more complex and time consuming, and require a high level of skill and support to minimize the potential for inappropriate non-conveyance. They’ve [service users] given up accessing some other avenues, GPs, NHS Direct, and that makes the decision more complicated. If you don’t work in here, the hardest decisions are heart attacks and road traffic accidents and cardiac arrest when in actual fact if you’re a paramedic, en route you know that if someone’s crashed their car, having a heart attack, been shot or whatever. They probably are going to go to hospital, 90% of the decision is already made. (Paramedic) The big jobs we used to deal with on a regular basis are now diluted and we’re receiving less training than we did two years ago. (Paramedic)
Performance regime and priorities
Paramedics were conscious of organisational pressures to meet various performance indicators including the eight minute response time target, reduced on-scene time and reduced rates of conveyance. However, there was resistance to allowing these to unduly influence patient care. If they need to go to hospital they go, if they don’t, they don’t. (Paramedic practitioner) Then you've got moralistic issue and decision-making of do I feel compelled to upgrade this to an immediate response because of time or am I happy to sit here for up to 2 hours and wait for a vehicle while I'm out of the system. So for patient safety, that is a decision where you say this patient is going to be safe to be left for two hours knowing that they can go into hospital and you may safety net with ‘if it gets worse phone 999’. And do you risk that. Do you make that decision and assume that responsibility or do you fear that if that if you leave them the ‘what if’ factor may kick in and then they could go into cardiac arrest. (Emergency care practitioner)
Access to appropriate care options
Conveyance to ED was not considered the best option for some patients (e.g. those with mental health problems, people requiring end of life care, the elderly, or patients with chronic conditions). However, in a number of cases where conveyance was deemed unnecessary, lack of access to alternative services or community resources including ECPs resulted in conveyance to ED. This was particularly frustrating for specialist paramedics with a remit to reduce ED admissions. Trouble is I’ve also had times where by trying to keep the patient at home, I’ve just spent ages on scene and they’ve ended up going in anyway. ‘Cos I’ve exhausted so many avenues trying to keep them at home, like the lady that just needs someone to sit. Ringing the GP, ringing intermediate care, ringing social workers or mental health teams. (Paramedic practitioner) I think the biggest risk in my decisions that I make for my patients today are that between midnight and 6am there aren’t as many options and often I would like to leave an old lady at home but the ECPs finish at two. So she’s not getting the very best decision for her. She’s gonna have to go to A&E … (Paramedic)
Disproportionate risk aversion
Non-conveyance was perceived as involving risk for both patient and paramedic. Varying levels of risk tolerance were apparent and to some extent influenced by competence, confidence or negative experiences. It’s that initial time from us saying, we’re leaving now and we’ve done x, y and z to refer you on to another service and from when that other healthcare professional takes over it’s that time that we are at most risk and it is the forefront of our mind when we make these decisions about whether it’s safe or not and whether it impacts on us and our professional registration. (Paramedic practitioner) It’s so much more now about covering yourself … I was speaking to a paramedic and he went ‘every single patient, I will refer. Even if it’s just be ringing up their doctor and saying I went out to this patient … ’ Which is not necessarily a bad thing but then I think well why do we need to do that with every single patient, for example someone that’s just cut their finger. (Paramedic)
Staff training and development
Paramedics identified the beneficial impact of additional training on their competence and confidence, supporting better decisions and enhancing communication with other clinicians. Such training was sometimes optional, relying on personal investment of time; consequently, staff in the same role may have different training/skills. The more I’ve learnt the more I’ve learnt about different conditions that I wasn’t aware of before or was not as aware of so it is enlightening … But I do worry about a lot of other people that haven’t done those courses and that will be encouraged to leave people at home. (Paramedic) … but every time you get nearly due your update it gets cancelled because of operational demands. It’s very short term management where people say we’ll make better decisions with more training but there just isn’t the investment. ‘Cos we can’t invest because we won't get the money if we don’t make the 8 minutes. (Paramedic) … at the minute, there’s no difference between my role and a paramedic in the sense that I’m going to specific jobs to facilitate non-transport, it’s just pot luck whether I turn up and can use my practitioner skills for non-transport. (Paramedic practitioner)
Communication and feedback to crews
Paramedics work in relative isolation compared to their hospital based colleagues and have to make important decisions at scene, without easy access to other opinions. There is a risk that decisions are based on partial knowledge of potential options when decision support was limited. Paramedics identified a range of passive support systems they consulted, such as pathway algorithms, e.g. decision aids for assessments to identify the most appropriate pathway for patients with suspected stroke, STEMI or major trauma. The electronic patient report form (ePRF) was being developed for crews to access information about local services and JRCALC (Joint Royal Colleges Ambulance Liaison Committee) clinical guidelines but the ePRF was not universally available. Perspectives on active support systems (e.g. clinical hubs based in control rooms and staffed by nurses, physicians or specialist paramedics) were mixed, with some reporting them to be helpful while others cited less favourable experiences.
Paramedics sometimes consulted informal peer networks when faced with difficult decisions or attempted to telephone the patient’s GP for advice. Difficulty in making contact with GPs, particularly out-of-hours, was an issue, and a variable that sponsored conveyance. There were also accounts of positive experiences and relationships with out-of-hours and other services (e.g. falls teams).
Information conveyed to crews when dispatched to calls had the potential to inform and frame crew expectations, but this information was often limited and potentially misleading. In the context of information constraints clinicians expressed that it was important to remain open minded, for example when attending ‘frequent callers’. Clinicians reported feeling ‘overloaded’ by the amount of information (e.g. policies, procedures, protocols) provided as internal communications. It was said to be challenging to access and keep up to date with information communicated via multiple channels and a common concern was the potential to miss something important. If there’s a high amount of clinical updates and a reduced amount of time. I think there’s a safety issue in that you’ll look at the red ones and then miss the green ones because you haven’t got much time or there’s so many of them that you can’t become versed with them all and therefore you will miss opportunities to be made aware or increase your knowledge about pathways. (Emergency care practitioner) I worry about some decisions that I’ve made because we never get feedback and I never ever get told whether I made the right decision to either leave somebody at home or take them to hospital and whether what treatment I did was right. If you take them to A&E it’s hard to get feedback. (Paramedic)
Limited awareness of alternative care options is likely to increase ED conveyance, regardless of appropriateness. Limited access to feedback represents a barrier to individual and organisational learning and improvement.
Ambulance service resources [staff, vehicles & equipment]
High demand strained ambulance service resources. Variations in access to specialist paramedics, vehicles, equipment and drugs had the potential to impact on decisions about patient care. The tension between service demands and availability of resources was identified as a source of pressure for staff. We’re often under resourced. We often don’t know where we can refer and what we can do. But also, there’s always that pressure that they need you to come clear for the next job so you’re rushing jobs. There’s always that element where you feel vulnerable because you’ve not got the time to do everything properly. (Paramedic)
In some instances, basic equipment (e.g. thermometers) was missing from vehicles, which meant clinical information could not be obtained. Participants also reported occasions when they had worked on vehicles containing equipment or drugs they were not trained to use. I’m conscious that I’ve been on a vehicle this week and the equipment on there, had things like a splint, that I’d never used before and I’m working with someone who is junior, who has been trained in it. You get those sorts of things. You also get that ambulance service staff are now purchasing their own equipment. (Paramedic)
Discussion
The findings from this research provide insight into nine types of transition decisions encountered by paramedics, identify seven overarching system risk factors influencing decisions and highlight challenges faced by paramedics in delivering safe care. The seven multi-level influences identified should not be considered discrete, but rather as overlapping and interrelated issues. Coping with the increasing demand for ambulance service care and a diverse set of clinical needs are key issues impacting on paramedics who are striving to meet patients’ needs as well as developing their own potential. The focus on reducing conveyance rates to ED intensifies the need to ensure that crews have the skills to be able to make appropriate conveyance decisions if potential risks to patients are to be minimized. This study also highlights the challenges of developing staff and ensuring that their skills are utilized where most needed within the context of organisational resource constraints and operational demands. There is evidence that specialist paramedics are having an impact on non-conveyance rates, with discharges of 20% or more compared with usual care,10,11 although, this higher level of education and training represents a minority of paramedics. It has also been recommended that more evidence is needed regarding the appropriateness and safety of conveyance decisions by staff in these specialist roles. 11
Non-conveyance decisions are problematic in terms of knowing what services are available and being able to access them, with conveyance to ED often used as the default option to reduce risk of delays or leaving patients unsupported. Fragmentation of provision, as evidenced in our study, is acknowledged in reports that emphasize the need for 24/7 seamless urgent and emergency care.18,19 Access to appropriate alternatives to ED also hinge upon working across professional and service boundaries, but perceptions of the ambulance service among other professionals as primarily a transport service remain a barrier. However, participants were optimistic that this barrier was being reduced through building trusting relationships and in the case of specialist roles, there are studies showing successful collaborative working with other health professionals. 10
Findings of risk aversion, including perceptions that highly detailed documentation was needed to support decisions, combined with mistrust of managerial support should anything go wrong following non-conveyance, are consistent with other research. 20
It was apparent that the extent and nature of demand for ambulance conveyances represent a notable source of strain and tension for individuals and organisations. Similar issues were identified in an ethnographic study of changes in the paramedic role which identified work intensification and a target culture as placing huge pressures on ‘road staff’. 21
The aim of this study was to explore multi-level system influences on decision making by paramedics, focussing on care transitions and potential risk factors. The findings highlight the increased scope and complexity of paramedic transition decisions. An increased focus on reducing conveyance to ED relies on the availability of suitable ambulance service resources and alternative care options for patients. Although the findings emphasize areas of system weaknesses, including structural and attitudinal constraints, there were specific aspects that were reported to be working well across the three Trusts, for example: specific care management pathways, local roles and ways of working, and technological initiatives that merit further investigation to inform service improvement.
Strengths and limitations
The use of multiple methods provided consistent evidence around key issues. The consistency of findings across participating Trusts suggests that the issues identified may be generic, and relevant to other ambulance services. The secondment of ambulance service staff as researchers allowed data to be compared from ‘insider’ and ‘outsider’ perspectives.
This was a relatively small scale qualitative study involving three Ambulance Service Trusts and did not include any direct measures of patient safety. The scope of the study was limited to a self-selected sample of paramedics (n = 50). Specialist paramedic roles represented a relatively small proportion of the overall sample. The perspective of linked services providers (e.g. ED, GPs and other care pathways) would have provided broader insight on the system influences examined from the ambulance service perspective.
Implications
The current study provides a new and in-depth understanding of decision making by paramedics. This is particularly important given the recent emphasis on ambulance services providing care closer to home. 5 The study highlights the increased complexity of paramedic decisions and system influences that may exacerbate risk. Failure to consider how ambulance services can best function within the wider NHS system of urgent and emergency care may negatively impact on patient care. For example, ambulance services need to ensure an appropriately skilled workforce and supportive culture, and the wider urgent and emergency care system level should provide access to appropriate patient care options.
Further research could explore the impact of enhanced skills on service delivery and how to balance the need for urgent and emergency care. This would also need to address barriers to training, development and skill use.
Limited and variable access to services in the wider health and social care system is a significant barrier to reducing inappropriate conveyance to ED. More research is needed to identify effective ways of improving the delivery of care across service boundaries, particularly for patients with limited options at present (e.g. mental health, end of life care, older patients). Research should address structural and attitudinal barriers and how these might be overcome.
