Rising demand for health care has prompted interest in new technologies to support a shift of care from hospital to community and primary care, which may require clinicians to undertake new working practices. A predictive risk stratification tool (Prism) was developed for use in primary care to estimate patients’ risk of an emergency hospital admission. As part of an evaluation of Prism, we aimed to understand what might be needed to bring Prism into effective use by exploring clinicians and practice managers’ attitudes and expectations about using it. We were informed by Normalisation Process Theory (NPT) which examines the work needed to bring an innovation into use. We conducted 4 focus groups and 10 interviews with a total of 43 primary care doctors and colleagues from 32 general practices. All were recorded and transcribed. Analysis focussed in particular on the construct of ‘coherence’ within NPT, which examines how people understand an innovation and its purpose. Respondents were in agreement that Prism was a technological formalisation of existing practice, and that it would function as a support to clinical judgment, rather than replacing it. There was broad consensus about the role it might have in delivering new models of care based on active management, but there were doubts about the scope for making a difference to some patients and about whether Prism could identify at-risk patients not already known to the clinical team. Respondents did not expect using the tool to be onerous, but were concerned about the work which might follow in delivering care. Any potential value would not be of the tool in isolation, but would depend on the availability of support services. Policy imperatives and the pressure of rising demand meant respondents were open to trying out Prism, despite underlying uncertainty about what difference it could make. Controlled Clinical Trials no. ISRCTN55538212 .

Background Older people who fall commonly present to the emergency ambulance service, and approximately 40% are not conveyed to the emergency department (ED), despite an historic lack of formal training for such decisions. This study aimed to understand the decision-making processes of emergency ambulance staff with older people who have fallen. Methods During 2005 ambulance staff in London tested a clinical assessment tool for use with the older person who had fallen. Documented use of the tool was low. Following the trial, 12 staff participated in semistructured interviews. Interviews were recorded and transcribed. Thematic analysis was carried out. Results The interviews revealed a similar assessment and decision-making process among participants: Prearrival: forming an early opinion from information from the emergency call. Initial contact: assessing the need for any immediate action and establishing a rapport. Continuing assessment: gathering and assimilating medical and social information. Making a conveyance decision: negotiation, referral and professional defence, using professional experience and instinct. Conclusions An assessment process was described that highlights the complexity of making decisions about whether or not to convey older people who fall and present to the emergency ambulance service, and a predominance of informal decision-making processes. The need for support for ambulance staff in this area was highlighted, generating a significant challenge to those with education roles in the ambulance service. Further research is needed to look at how new care pathways, which offer an alternative to the ED may influence decision making around non-conveyance.

Qualitative research methods are increasingly used within clinical trials to address broader research questions than can be addressed by quantitative methods alone. These methods enable health professionals, service users, and other stakeholders to contribute their views and experiences to evaluation of healthcare treatments, interventions, or policies, and influence the design of trials. Qualitative data often contribute information that is better able to reform policy or influence design.

Objectives Worldwide, emergency healthcare systems are under intense pressure from ever-increasing demand and evidence is urgently needed to understand how this can be safely managed. An estimated 10%–43% of emergency department patients could be treated by primary care services. In England, this has led to a policy proposal and £100 million of funding (US$130 million), for emergency departments to stream appropriate patients to a co-located primary care facility so they are ‘free to care for the sickest patients’. However, the research evidence to support this initiative is weak. Design Rapid realist literature review. Setting Emergency departments. Inclusion criteria Articles describing general practitioners working in or alongside emergency departments. Aim To develop context-specific theories that explain how and why general practitioners working in or alongside emergency departments affect: patient flow; patient experience; patient safety and the wider healthcare system. Results Ninety-six articles contributed data to theory development sourced from earlier systematic reviews, updated database searches (Medline, Embase, CINAHL, Cochrane DSR & CRCT, DARE, HTA Database, BSC, PsycINFO and SCOPUS) and citation tracking. We developed theories to explain: how staff interpret the streaming system; different roles general practitioners adopt in the emergency department setting (traditional, extended, gatekeeper or emergency clinician) and how these factors influence patient (experience and safety) and organisational (demand and cost-effectiveness) outcomes. Conclusions Multiple factors influence the effectiveness of emergency department streaming to general practitioners; caution is needed in embedding the policy until further research and evaluation are available. Service models that encourage the traditional general practitioner approach may have shorter process times for non-urgent patients; however, there is little evidence that this frees up emergency department staff to care for the sickest patients. Distinct primary care services offering increased patient choice may result in provider-induced demand. Economic evaluation and safety requires further research. PROSPERO registration number CRD42017069741.

We aim to determine clinical and cost-effectiveness of a paramedic protocol for the care of older people who fall. We undertook a cluster randomized trial in 3 UK ambulance services between March 2011 and June 2012. We included patients aged 65 years or older after an emergency call for a fall, attended by paramedics based at trial stations. Intervention paramedics could refer the patient to a community-based falls service instead of transporting the patient to the emergency department. Control paramedics provided care as usual. The primary outcome was subsequent emergency contacts or death. One hundred five paramedics based at 14 intervention stations attended 3,073 eligible patients; 110 paramedics based at 11 control stations attended 2,841 eligible patients. We analyzed primary outcomes for 2,391 intervention and 2,264 control patients. One third of patients made further emergency contacts or died within 1 month, and two thirds within 6 months, with no difference between groups. Subsequent 999 call rates within 6 months were lower in the intervention arm (0.0125 versus 0.0172; adjusted difference -0.0045; 95% confidence interval -0.0073 to -0.0017). Intervention paramedics referred 8% of patients (204/2,420) to falls services and left fewer patients at the scene without any ongoing care. Intervention patients reported higher satisfaction with interpersonal aspects of care. There were no other differences between groups. Mean intervention cost was $23 per patient, with no difference in overall resource use between groups at 1 or 6 months. A clinical protocol for paramedics reduced emergency ambulance calls for patients attended for a fall safely and at modest cost.

Objective: In most UK ambulance services, crews attending someone who has phoned the emergency services on ‘999’ will take the patient to hospital, unless the patient makes the decision to stay at home (or wherever they happen to be when the ambulance arrives). Safety concerns have been raised about non-conveyance decisions. Weunder took a study of one UK Ambulance Service to examine ambulance crew members’ views on how decision-making about non-conveyance works in practice in relation to non-urgent calls. Methods: A total of 25 paramedics took part in three focus groups. Focus groups were transcribed and analysed thematically. Results: The ambulance service's apparently straight forward guidance on decision-making about non-conveyance proved tricky in the messiness of the real world, for two reasons. The first was to do with the notion of the patient's capacity to make decisions and how this was interpreted. The second was to do with the complexity of the decision-making process, in which the patient, the crew and, in many cases, family or carers often take part in negotiation and de facto joint decision-making. Conclusions: There is a mismatch between policy and practice in relation to non-conveyance decisions. Findings should be built into research and service development in this rapidly changing field of practice in emergency and/or unscheduled care. The commonly accepted perspective on shared decision-making should be extended to include the context of ‘999’ ambulance calls.
