Multiple triangulation and collaborative research using qualitative methods to explore decision making in pre-hospital emergency care.

BACKGROUND: Paramedics make important and increasingly complex decisions at scene about patient care. Patient safety implications of influences on decision making in the pre-hospital setting were previously under-researched. Cutting edge perspectives advocate exploring the whole system rather than individual influences on patient safety. Ethnography (the study of people and cultures) has been acknowledged as a suitable method for identifying health care issues as they occur within the natural context. In this paper we compare multiple methods used in a multi-site, qualitative study that aimed to identify system influences on decision making. METHODS: The study was conducted in three NHS Ambulance Trusts in England and involved researchers from each Trust working alongside academic researchers. Exploratory interviews with key informants e.g. managers (n = 16) and document review provided contextual information. Between October 2012 and July 2013 researchers observed 34 paramedic shifts and ten paramedics provided additional accounts via audio-recorded 'digital diaries' (155 events). Three staff focus groups (total n = 21) and three service user focus groups (total n = 23) explored a range of experiences and perceptions. Data collection and analysis was carried out by academic and ambulance service researchers as well as service users. Workshops were held at each site to elicit feedback on the findings and facilitate prioritisation of issues identified. RESULTS: The use of a multi-method qualitative approach allowed cross-validation of important issues for ambulance service staff and service users. A key factor in successful implementation of the study was establishing good working relationships with academic and ambulance service teams. Enrolling at least one research lead at each site facilitated the recruitment process as well as study progress. Active involvement with the study allowed ambulance service researchers and service users to gain a better understanding of the research process. Feedback workshops allowed stakeholders to discuss and prioritise findings as well as identify new research areas. CONCLUSION: Combining multiple qualitative methods with a collaborative research approach can facilitate exploration of system influences on patient safety in under-researched settings. The paper highlights empirical issues, strengths and limitations for this approach. Feedback workshops were effective for verifying findings and prioritising areas for future intervention and research.

Patient and public involvement in emergency care research.

Patients participate in emergency care research and are the intended beneficiaries of research findings. The public provide substantial funding for research through taxation and charitable donations. If we do research to benefit patients and the public are funding the research, then patients and the public should be involved in the planning, prioritisation, design, conduct and oversight of research, yet patient and public involvement (or more simply, public involvement, since patients are also members of the public) has only recently developed in emergency care research. In this article, we describe what public involvement is and how it can help emergency care research. We use the development of a pioneering public involvement group in emergency care, the Sheffield Emergency Care Forum, to provide insights into the potential and challenges of public involvement in emergency care research.

Variation in avoidable emergency admissions: multiple case studies of emergency and urgent care systems.

OBJECTIVE: To identify factors affecting variation in avoidable emergency admissions that are not usually identified in statistical regression. METHODS: As part of an ethnographic residual analysis, we compared six emergency and urgent care systems in England, interviewing 82 commissioners and providers of key emergency and urgent care services. RESULTS: There was variation between the six cases in how interviewees described three parts of their emergency and urgent care systems. First, interviewees' descriptions revealed variation in the availability of services before patients decided to attend emergency departments. Poor availability of general practice out of hours services in some of the cases reportedly made attendance at emergency departments the easier option for patients. Second, there was variation in how interviewees described patients being dealt with during their emergency department visit in terms of availability of senior review by specialists and in coding practices when patients were at risk of breaching the NHS's 4-hour waiting time target. Third, there was variability in services described as facilitating discharge home from emergency departments. In some cases, emergency department staff described dealing with multiple agencies in multiple localities outside the hospital, making admission the easier option. In other cases, proactive multidisciplinary rapid assessment teams were described as available to avoid admissions. Perceptions of resources available out of hours and the extent of integration between different health services, and between health and social services, also differed by case. CONCLUSIONS: This comparative case study approach identified further factors that may affect avoidable emergency admissions. Initiatives to improve GP out of hours services, make coding more accurately reflect patient experience, increase senior review in emergency departments, offer proactive multidisciplinary admission avoidance teams, improve the availability of out of hours care in the wider emergency and urgent care system, and increase service integration may reduce avoidable admissions. Evaluation of such initiatives would be necessary before wide-scale adoption.

A qualitative study of systemic influences on paramedic decision making: care transitions and patient safety.

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).

A system-wide approach to explaining variation in potentially avoidable emergency admissions: national ecological study.

BACKGROUND: Some emergency admissions can be avoided if acute exacerbations of health problems are managed by the range of health services providing emergency and urgent care. AIM: To identify system-wide factors explaining variation in age sex adjusted admission rates for conditions rich in avoidable admissions. DESIGN: National ecological study. SETTING: 152 emergency and urgent care systems in England. METHODS: Hospital Episode Statistics data on emergency admissions were used to calculate an age sex adjusted admission rate for conditions rich in avoidable admissions for each emergency and urgent care system in England for 2008-2011. RESULTS: There were 3 273 395 relevant admissions in 2008-2011, accounting for 22% of all emergency admissions. The mean age sex adjusted admission rate was 2258 per year per 100 000 population, with a 3.4-fold variation between systems (1268 and 4359). Factors beyond the control of health services explained the majority of variation: unemployment rates explained 72%, with urban/rural status explaining further variation (R(2)=75%). Factors related to emergency departments, hospitals, emergency ambulance services and general practice explained further variation (R(2)=85%): the attendance rate at emergency departments, percentage of emergency department attendances converted to admissions, percentage of emergency admissions staying less than a day, percentage of emergency ambulance calls not transported to hospital and perceived access to general practice within 48 h. CONCLUSIONS: Interventions to reduce avoidable admissions should be targeted at deprived communities. Better use of emergency departments, ambulance services and primary care could further reduce avoidable emergency admissions.
