Programme theories to describe how different general practitioner service models work in different contexts in or alongside emergency departments (GP-ED): realist evaluation

BACKGROUND

Addressing increasing patient demand and improving ED patient flow is a key ambition for NHS England. Delivering general practitioner (GP) services in or alongside EDs (GP-ED) was advocated in 2017 for this reason, supported by £100 million (US$130 million) of capital funding. Current evidence shows no overall improvement in addressing demand and reducing waiting times, but considerable variation in how different service models operate, subject to local context.

METHODS

We conducted mixed-methods analysis using inductive and deductive approaches for qualitative (observations, interviews) and quantitative data (time series analyses of attendances, reattendances, hospital admissions, length of stay) based on previous research using a purposive sample of 13 GP-ED service models (3 inside-integrated, 4 inside-parallel service, 3 outside-onsite and 3 with no GPs) in England and Wales. We used realist methodology to understand the relationship between contexts, mechanisms and outcomes to develop programme theories about how and why different GP-ED service models work.

RESULTS

GP-ED service models are complex, with variation in scope and scale of the service, influenced by individual, departmental and external factors. Quantitative data were of variable quality: overall, no reduction in attendances and waiting times, a mixed picture for hospital admissions and length of hospital stay. Our programme theories describe how the GP-ED service models operate: inside the ED, integrated with patient flow and general ED demand, with a wider GP role than usual primary care; outside the ED, addressing primary care demand with an experienced streaming nurse facilitating the 'right patients' are streamed to the GP; or within the ED as a parallel service with most variability in the level of integration and GP role.

CONCLUSION

GP-ED services are complex . Our programme theories inform recommendations on how services could be modified in particular contexts to address local demand, or whether alternative healthcare services should be considered.

Evaluation of different models of general practitioners working in or alongside emergency departments: a mixed-methods realist evaluation

Background

Emergency healthcare services are under intense pressure to meet increasing patient demands. Many patients presenting to emergency departments could be managed by general practitioners in general practitioner-emergency department service models.

Objectives

To evaluate the effectiveness, safety, patient experience and system implications of the different general practitioner-emergency department models.

Design

Mixed-methods realist evaluation.

Methods

Phase 1 (2017-8), to understand current practice: rapid realist literature review, national survey and follow-up key informant interviews, national stakeholder event and safety data analysis. Phase 2 (2018-21), to collect and analyse qualitative (observations, interviews) and quantitative data (time series analysis); cost-consequences analysis of routine data; and case site data for 'marker condition' analysis from a purposive sample of 13 case sites in England and Wales. Phase 3 (2021-2), to conduct mixed-methods analysis for programme theory and toolkit development.

Results

General practitioners commonly work in emergency departments, but delivery models vary widely in terms of the scope of the general practitioner role and the scale of the general practitioner service. We developed a taxonomy to describe general practitioner-emergency department service models (Integrated with the emergency department service, Parallel within the emergency department, Outside the emergency department on the hospital site) and present a programme theory as principal output of the study to describe how these service models were observed to operate. Routine data were of variable quality, limiting our analysis. Time series analysis demonstrated trends across intervention sites for: increased time spent in the emergency department; increased emergency department attendances and reattendances; and mixed results for hospital admissions. Evidence on patient experience was limited but broadly supportive; we identified department-level processes to optimise the safety of general practitioner-emergency department models.

Limitations

The quality, heterogeneity and extent of routine emergency department data collection during the study period limited the conclusions. Recruitment was limited by criteria for case sites (time series requirements) and individual patients (with 'marker conditions'). Pandemic and other pressures limited data collection for marker condition analysis. Data collected and analysed were pre pandemic; new approaches such as 'telephone first' and their relevance to our findings remains unexplored.

Conclusion

Findings suggest that general practitioner-emergency department service models do not meet the aim of reducing the overall emergency department waiting times and improving patient flow with limited evidence of cost savings. Qualitative data indicated that general practitioners were often valued as members of the wider emergency department team. We have developed a toolkit, based on our findings, to provide guidance for implementing and delivering general practitioner-emergency department services.

Future work

The emergency care data set has since been introduced across England to help standardise data collection to facilitate further research. We would advocate the systematic capture of patient experience measures and patient-reported outcome measures as part of routine care. More could be done to support the development of the general practitioner in emergency department role, including a core set of competencies and governance structure, to reflect the different general practitioner-emergency department models and to evaluate the effectiveness and cost effectiveness to guide future policy.

An exploration of the experiences and self-generated strategies used when navigating everyday life with Long Covid

BACKGROUND

Around one in ten people who contract Covid-19 report ongoing symptoms or 'Long Covid'. Without any known interventions to cure the condition, forms of self-management are routinely prescribed by healthcare professionals and described by people with the condition. However, there is limited research exploring what strategies are used to navigate everyday life with Long Covid, and experiences that initiate development of these strategies. Our study aimed to explore the range and influence of self-generated strategies used by people with Long Covid to navigate everyday life within the context of their own condition.

METHODS

Forming part of the Long Covid Personalised Self-managemenT support co-design and EvaluatioN (LISTEN) project, we conducted a qualitative study using narrative interviews with adults who were not hospitalised with Covid-19. Participants aged over 18 years, who self-identified with Long Covid, were recruited from England and Wales. Data were analysed with patient contributors using a reflexive thematic analysis.

RESULTS

Eighteen participants (mean age = 44 years, SD = 13 years) took part in interviews held between December 2021 and February 2022. Themes were constructed which depicted 1) the landscape behind the Long Covid experience and 2) the everyday experience of participants' Long Covid. The everyday experience comprised a combination of physical, emotional, and social factors, forming three sub-themes: centrality of physical symptoms, navigating 'experts' and the 'true colour' of personal communities, and a rollercoaster of psychological ambiguity). The third theme, personal strategies to manage everyday life was constructed from participants' unique presentations and self-generated solutions to manage everyday life. This comprised five sub-themes: seeking reassurance and knowledge, developing greater self-awareness through monitoring, trial and error of 'safe' ideas, building in pleasure and comfort, and prioritising 'me'.

CONCLUSIONS

Among this sample of adults with Long Covid, their experiences highlighted the unpredictable nature of the condition but also the use of creative and wide ranging self-generated strategies. The results offer people with Long Covid, and healthcare professionals supporting them, an overview of the collective evidence relating to individuals' self-management which can enable ways to live 'better' and regain some sense of identity whilst facing the impact of a debilitating, episodic condition.

Prehospital transdermal glyceryl trinitrate for ultra-acute ischaemic stroke: data from the RIGHT-2 randomised sham-controlled ambulance trial

BACKGROUND

The effect of transdermal glyceryl trinitrate (GTN, a nitrovasodilator) on clinical outcome when administered before hospital admission in suspected stroke patients is unclear. Here, we assess the safety and efficacy of GTN in the prespecified subgroup of patients who had an ischaemic stroke within the Rapid Intervention with Glyceryl trinitrate in Hypertensive stroke Trial-2 (RIGHT-2).

METHODS

RIGHT-2 was an ambulance-based multicentre sham-controlled blinded-endpoint study with patients randomised within 4 hours of onset. The primary outcome was a shift in scores on the modified Rankin scale (mRS) at day 90. Secondary outcomes included death; a global analysis (Wei-Lachin test) containing Barthel Index, EuroQol-5D, mRS, telephone interview for cognitive status-modified and Zung depression scale; and neuroimaging-determined 'brain frailty' markers. Data were reported as n (%), mean (SD), median [IQR], adjusted common OR (acOR), mean difference or Mann-Whitney difference (MWD) with 95% CI.

RESULTS

597 of 1149 (52%) patients had a final diagnosis of ischaemic stroke; age 75 (12) years, premorbid mRS>2 107 (18%), Glasgow Coma Scale 14 (2) and time from onset to randomisation 67 [45, 108] min. Neuroimaging 'brain frailty' was common: median score 2 [2, 3] (range 0-3). At day 90, GTN did not influence the primary outcome (acOR for increased disability 1.15, 95% CI 0.85 to 1.54), death or global analysis (MWD 0.00, 95% CI -0.10 to 0.09). In subgroup analyses, there were non-significant interactions suggesting GTN may be associated with more death and dependency in participants randomised within 1 hour of symptom onset and in those with more severe stroke.

CONCLUSIONS

In patients who had an ischaemic stroke, ultra-acute administration of transdermal GTN in the ambulance did not improve clinical outcomes in a population with more clinical and radiological frailty than seen in previous in-hospital trials.

Nurse-delivered sleep restriction therapy in primary care for adults with insomnia disorder: a mixed-methods process evaluation

BACKGROUND

Sleep restriction therapy (SRT) is a behavioural therapy for insomnia.

AIM

To conduct a process evaluation of a randomised controlled trial comparing SRT delivered by primary care nurses plus a sleep hygiene booklet with the sleep hygiene booklet only for adults with insomnia disorder.

DESIGN AND SETTING

A mixed-methods process evaluation in a general practice setting.

METHOD

Semi-structured interviews were conducted in a purposive sample of patients receiving SRT, the practice nurses who delivered the therapy, and also GPs or practice managers at the participating practices. Qualitative data were explored using framework analysis, and integrated with nurse comments and quantitative data, including baseline Insomnia Severity Index score and serial sleep efficiency outcomes to investigate the relationships between these.

RESULTS

In total, 16 patients, 13 nurses, six practice managers, and one GP were interviewed. Patients had no previous experience of behavioural therapy, needed flexible appointment times, and preferred face-to-face consultations; nurses felt prepared to deliver SRT, accommodating patient concerns, tailoring therapy, and negotiating sleep timings despite treatment complexity and delays between training and intervention delivery. How the intervention produced change was explored, including patient and nurse interactions and patient responses to SRT. Difficulties maintaining SRT, negative attitudes towards treatment, and low self-efficacy were highlighted. Contextual factors, including freeing GP time, time constraints, and conflicting priorities for nurses, with suggestions for alternative delivery options, were raised. Participants who found SRT a positive process showed improvements in sleep efficiency, whereas those who struggled did not.

CONCLUSION

SRT was successfully delivered by practice nurses and was generally well received by patients, despite some difficulties delivering and applying the intervention in practice.

Co-Design of a Reusable Learning Object (RLO) to Address Caregiver Responsive Infant Feeding Behaviours (CRIB) to Prevent Childhood Obesity: A Mixed-Method Protocol

Responsive infant feeding is a key strategy for childhood obesity prevention. Responsive feeding involves caregivers responding to infant hunger and satiety cues in a timely and developmentally appropriate manner. There is a dearth of evidence-based information and guidance for caregivers on how to responsively feed their infants. The aim of this research is to co-design a Reusable Learning Object (RLO) and guidance infographic to improve caregiver awareness, understanding and use of responsive infant feeding behaviours. The Capability, Opportunity, Motivation and Behaviour (COM-B) model of behaviour change and the Aim, Storyboarding, Populate specification, Implement media, Review and release prototype, and Evaluate (ASPIRE) approach for digital intervention co-design will be utilised. Four co-design workshops with caregivers of infants and healthcare professionals (HCPs) will determine priority RLO content. Content analysis will enable RLO development and process reporting. Formative and summative surveys will be conducted to evaluate the usability of the RLO, its impact on caregivers and its potential implementation into NHS care pathways. The output will be a RLO on responsive feeding for caregivers and an infographic for HCPs/support workers which will contribute to a future obesity prevention intervention. The findings will be disseminated to stakeholders and submitted for publication in a peer-reviewed journal.

Development of indicators for avoidable emergency medical service calls by mapping paramedic clinical impression codes to ambulatory care sensitive conditions and mental health conditions in the UK and Canada

OBJECTIVE

Paramedic assessment data have not been used for research on avoidable calls. Paramedic impression codes are designated by paramedics on responding to a 911/999 medical emergency after an assessment of the presenting condition. Ambulatory care sensitive conditions (ACSCs) are non-acute health conditions not needing hospital admission when properly managed. This study aimed to map the paramedic impression codes to ACSCs and mental health conditions for use in future research on avoidable 911/999 calls.

DESIGN

Mapping paramedic impression codes to existing definitions of ACSCs and mental health conditions.

SETTING

East Midlands Region, UK and Southern Ontario, Canada.

PARTICIPANTS

Expert panel from the UK-Canada Emergency Calls Data analysis and GEospatial mapping (EDGE) Consortium.

RESULTS

Mapping was iterative first identifying the common ACSCs shared between the two countries then identifying the respective clinical impression codes for each country that mapped to those shared ACSCs as well as to mental health conditions. Experts from the UK-Canada EDGE Consortium contributed to both phases and were able to independently match the codes and then compare results. Clinical impression codes for paramedics in the UK were more extensive than those in Ontario. The mapping revealed some interesting inconsistencies between paramedic impression codes but also demonstrated that it was possible.

CONCLUSION

This is an important first step in determining the number of ASCSs and mental health conditions that paramedics attend to, and in examining the clinical pathways of these individuals across the health system. This work lays the foundation for international comparative health services research on integrated pathways in primary care and emergency medical services.

An early warning precision public health approach for assessing COVID-19 vulnerability in the UK: the Moore-Hill Vulnerability Index (MHVI)

BACKGROUND

Most COVID-19 vulnerability indices rely on measures that are biased by rates of exposure or are retrospective like mortality rates that offer little opportunity for intervention. The Moore-Hill Vulnerability Index (MHVI) is a precision public health early warning alternative to traditional infection fatality rates that presents avenues for mortality prevention.

METHODS

We produced an infection-severity vulnerability index by calculating the proportion of all recorded positive cases that were severe and attended by ambulances at small area scale for the East Midlands of the UK between May 2020 and April 2022. We produced maps identifying regions with high and low vulnerability, investigated the accuracy of the index over shorter and longer time periods, and explored the utility of the MHVI compared to other common proxy measures and indices. Analysis included exploring the correlation between our novel index and the Index of Multiple Deprivation (IMD).

RESULTS

The MHVI captures geospatial dynamics that single metrics alone often overlook, including the compound health challenges associated with disadvantaged and declining coastal towns inhabited by communities with post-industrial health legacies. A moderate negative correlation between MHVI and IMD reflects spatial analysis which suggests that high vulnerability occurs in affluent rural as well as deprived coastal and urban communities. Further, the MHVI estimates of severity rates are comparable to infection fatality rates for COVID-19.

CONCLUSIONS

The MHVI identifies regions with known high rates of poor health outcomes prior to the pandemic that case rates or mortality rates alone fail to identify. Pre-hospital early warning measures could be utilised to prevent mortality during a novel pandemic.

Understanding colorectal cancer patient follow-up: a qualitative interview study

PURPOSE

There are increasing numbers of patients who have been treated for colorectal cancer (CRC) who struggle with ongoing physical and psychological symptoms. 'Cancer survivor' is often used to describe these patients but this terminology remains controversial. This study sought to understand the follow-up experience of CRC patients in the UK and identify the terminology they prefer following diagnosis and treatment.

METHODS

Purposeful sampling of patients from specialist CRC follow-up clinics was performed until data saturation was achieved. Two 1:1 semi-structured qualitative interviews were performed for each participant. Data were analysed thematically.

RESULTS

Seventeen participants, median age = 62, 53% male were interviewed. Several themes were identified. Of note, fear of cancer recurrence dominates patients' agendas at follow-up appointments. There are also clinical and administrative barriers to discussing symptoms including being embarrassed, feeling that their symptoms were not relevant or not having enough time to discuss issues. However, there are several methods which may improve this, such as through the use of video consultations and questionnaires. In addition, patients identified inadequate holistic support despite significant psychological and social distress. Our data suggest that labelling a diverse group of patients as 'cancer survivors' can be problematic.

CONCLUSION

It is important that clinicians systematically screen patients for symptoms that are known to occur following treatment. Clinicians and patients should have routine access to pathways and programmes that can support patients in navigating their life after cancer therapy.

Prehospital transdermal glyceryl trinitrate in patients with ultra-acute presumed stroke (RIGHT-2): effects on outcomes at day 365 in a randomised, sham-controlled, blinded, phase III, superiority ambulance-based trial

Background

The Rapid Intervention with Glyceryl Trinitrate in Hypertensive Stroke Trial-2 (RIGHT-2) reported no overall treatment difference between glyceryl trinitrate (GTN) and sham at day 90. Here we assess participants' outcomes 1 year after randomisation.

Methods

RIGHT-2 was an ambulance-based prospective randomised controlled trial where patients with presumed stroke and systolic blood pressure (BP) of >120 mm Hg received either GTN (5 mg/day) or sham patch. Centralised blinded telephone follow-up was performed at days 90 (primary endpoint) and 365 (secondary endpoint). The lead outcome was dependency assessed with the modified Rankin Scale (mRS).

Results

1149 patients were recruited to RIGHT-2 between October 2015 and May 2018, and 1097 (95.5%) had outcome data recorded at day 365. At baseline, the patients were; female (48%), had a mean age of 73 (15) years, BP of 162 (25)/92 (18) mm Hg, onset to randomisation of 70 (45-115) min, diagnosis of ischaemic stroke (52%), intracerebral haemorrhage (ICH) (13%), transient ischaemic attack (TIA) (9%) and mimics (26%). There was no effect of GTN on mRS score at day 365 in participants with confirmed stroke/TIA (adjusted common odds ratio (acOR) 1.10, 95% CI 0.86 to 1.42) or in all patients. In patients randomised to GTN, mRS at day 365 tended to be worse in those with ICH (acOR 1.65, 95% CI 0.84 to 3.25) and better in those with a mimic diagnosis (acOR 0.53, 95% CI 0.33 to 0.84).

Conclusion

At 1 year post randomisation, dependency did not differ between GTN and sham treatment in either the target population or overall. In prespecified subgroup analyses, GTN was associated with reduced dependency in participants with a final diagnosis of mimic and a non-significant worse outcome in participants with ICH.

The effect of specific learning difficulties on general practice written and clinical assessments

BACKGROUND

Substantial numbers of medical students and doctors have specific learning difficulties (SpLDs) and failure to accommodate their needs can disadvantage them academically. Evidence about how SpLDs affect performance during postgraduate general practice (GP) specialty training across the different licencing assessments is lacking. We aimed to investigate the performance of doctors with SpLDs across the range of licencing assessments.

METHODS

We adopted the social model of disability as a conceptual framework arguing that problems of disability are societal and that barriers that restrict life choices for people with disabilities need to be addressed. We used a longitudinal design linking Multi-Specialty Assessment (MSRA) records from 2016 and 2017 with their Applied Knowledge Test (AKT), Clinical Skills Assessment (CSA), Recorded Consultation Assessment (RCA) and Workplace Based Assessment (WPBA) outcomes up to 2021. Multivariable logistic regression models accounting for prior attainment and demographics were used to determine the SpLD doctors' likelihood of passing licencing assessments.

RESULTS

The sample included 2070 doctors, with 214 (10.34%) declaring a SpLD. Candidates declaring a SpLD were significantly less likely to pass the CSA (OR 0.43, 95% CI 0.26, 0.71, p = 0.001) but not the AKT (OR 0.96, 95% CI 0.44, 2.09, p = 0.913) or RCA (OR 0.81, 95% CI 0.35, 1.85, p = 0.615). Importantly, they were significantly more likely to have difficulties with WPBA (OR 0.28, 95% CI 0.20, 0.40, p < 0.001). When looking at licencing tests subdomains, doctors with SpLD performed significantly less well on the CSA Interpersonal Skills (B = -0.70, 95% CI -1.2, -0.19, p = 0.007) and the RCA Clinical Management Skills (B = -1.68, 95% CI -3.24, -0.13, p = 0.034).

CONCLUSIONS

Candidates with SpLDs encounter difficulties in multiple domains of the licencing tests and during their training. More adjustments tailored to their needs should be put in place for the applied clinical skills tests and during their training.

Building an understanding of Ethnic minority people's Service Use Relating to Emergency care for injuries: the BE SURE study protocol

INTRODUCTION

Injuries are a major public health problem which can lead to disability or death. However, little is known about the incidence, presentation, management and outcomes of emergency care for patients with injuries among people from ethnic minorities in the UK. The aim of this study is to investigate what may differ for people from ethnic minorities compared with white British people when presenting with injury to ambulance and Emergency Departments (EDs).

METHODS AND ANALYSIS

This mixed methods study covers eight services, four ambulance services (three in England and one in Scotland) and four hospital EDs, located within each ambulance service. The study has five Work Packages (WP): (WP1) scoping review comparing mortality by ethnicity of people presenting with injury to emergency services; (WP2) retrospective analysis of linked NHS routine data from patients who present to ambulances or EDs with injury over 5 years (2016-2021); (WP3) postal questionnaire survey of 2000 patients (1000 patients from ethnic minorities and 1000 white British patients) who present with injury to ambulances or EDs including self-reported outcomes (measured by Quality of Care Monitor and Health Related Quality of Life measured by SF-12); (WP4) qualitative interviews with patients from ethnic minorities (n=40) and focus groups-four with asylum seekers and refugees and four with care providers and (WP5) a synthesis of quantitative and qualitative findings.

ETHICS AND DISSEMINATION

This study received a favourable opinion by the Wales Research Ethics Committee (305391). The Health Research Authority has approved the study and, on advice from the Confidentiality Advisory Group, has supported the use of confidential patient information without consent for anonymised data. Results will be shared with ambulance and ED services, government bodies and third-sector organisations through direct communications summarising scientific conference proceedings and publications.

External validation of the Manchester Acute Coronary Syndromes ECG risk model within a pre-hospital setting

OBJECTIVES

The Manchester Acute Coronary Syndromes ECG (MACS-ECG) prediction model calculates a score based on objective ECG measurements to give the probability of a non-ST elevation myocardial infarction (NSTEMI). The model showed good performance in the emergency department (ED), but its accuracy in the pre-hospital setting is unknown. We aimed to externally validate MACS-ECG in the pre-hospital environment.

METHODS

We undertook a secondary analysis from the Pre-hospital Evaluation of Sensitive Troponin (PRESTO) study, a multi-centre prospective study to validate decision aids in the pre-hospital setting (26 February 2019 to 23 March 2020). Patients with chest pain where the treating paramedic suspected acute coronary syndrome were included. Paramedics collected demographic and historical data and interpreted ECGs contemporaneously (as 'normal' or 'abnormal'). After completing recruitment, we analysed ECGs to calculate the MACS-ECG score, using both a pre-defined threshold and a novel threshold that optimises sensitivity to differentiate AMI from non-AMI. This was compared with subjective ECG interpretation by paramedics. The diagnosis of AMI was adjudicated by two investigators based on serial troponin testing in hospital.

RESULTS

Of 691 participants, 87 had type 1 AMI and 687 had complete data for paramedic ECG interpretation. The MACS-ECG model had a C-index of 0.68 (95% CI: 0.61 to 0.75). At the pre-determined cut-off, MACS-ECG had 2.3% (95% CI: 0.3% to 8.1%) sensitivity, 99.5% (95% CI: 98.6% to 99.9%) specificity, 40.0% (95% CI: 10.2% to 79.3%) positive predictive value (PPV) and 87.6% (87.3% to 88.0%) negative predictive value (NPV). At the optimal threshold for sensitivity, MACS-ECG had 50.6% sensitivity (39.6% to 61.5%), 83.1% specificity (79.9% to 86.0%), 30.1% PPV (24.7% to 36.2%) and 92.1% NPV (90.4% to 93.5%). In comparison, paramedics had a sensitivity of 71.3% (95% CI: 60.8% to 80.5%) with 53.8% (95% CI: 53.8% to 61.8%) specificity, 19.7% (17.2% to 22.45%) PPV and 93.3% (90.8% to 95.1%) NPV.

CONCLUSION

Neither MACS-ECG nor paramedic ECG interpretation had a sufficiently high PPV or NPV to 'rule in' or 'rule out' NSTEMI alone.

Patient, family member, and ambulance staff experiences of prehospital acute pain management in adults: A systematic review and meta-synthesis

Background

We aimed to synthesize the qualitative experiences of patients, their family members, and ambulance staff involved in the prehospital management of acute pain in adults and generate recommendations to improve the quality of care.

Methods

A systematic review was conducted following the enhancing transparency in reporting the synthesis of qualitative research (ENTREQ) guidelines. We searched from inception to June 2021: MEDLINE, CINAHL Complete, PsycINFO and Web of Science (search alerts were screened up to December 2021). Articles were eligible for inclusion if they reported qualitative data and were published in the English language. The Critical Appraisal Skills Program for qualitative studies checklist was used to assess risk of bias, thematic synthesis was performed on included studies and recommendations for clinical practice improvement were generated.

Results

Twenty-five articles were included in the review, representing over 464 patients, family members, and ambulance staff from 8 countries. Six analytical themes and several recommendations to improve clinical practice were generated. Strengthening the patient-clinician relationship by building trust, promoting patient empowerment, addressing patient needs and expectations, and providing a holistic approach to pain treatment is key to improving prehospital pain management in adults. Shared pain management guidelines and training across the prehospital and emergency department intersection should improve the patient journey.

Conclusion

Interventions and guidelines that strengthen the patient-clinician relationship and span the prehospital and emergency department phase of care are likely to improve the quality of care for adults suffering acute pain in the prehospital setting.

Community First Responders' Contribution to Emergency Medical Service Provision in the United Kingdom

STUDY OBJECTIVE

We aimed to investigate community first responders' contribution to emergency care provision in terms of number, rate, type, and location of calls and characteristics of patients attended.

METHODS

We used a retrospective observational design analyzing routine data from electronic clinical records from 6 of 10 ambulance services in the United Kingdom during 2019. Descriptive statistics, including numbers and frequencies, were used to illustrate characteristics of incidents and patients that the community first responders attended first in both rural and urban areas.

RESULTS

The data included 4.5 million incidents during 1 year. The community first responders first attended a higher proportion of calls in rural areas compared with those in urban areas (3.90% versus 1.48 %). In rural areas, the community first responders also first attended a higher percentage of the most urgent call categories, 1 and 2. The community first responders first attended more than 9% of the total number of category 1 calls and almost 5% of category 2 calls. The community first responders also attended a higher percentage of the total number of cardiorespiratory and neurological/endocrine conditions. They first attended 6.5% of the total number of neurological/endocrine conditions and 5.9% of the total number of cardiorespiratory conditions. Regarding arrival times in rural areas, the community first responders attended higher percentages (more than 6%) of the total number of calls that had arrival times of less than 7 minutes or more than 60 minutes.

CONCLUSION

In the United Kingdom, community first responders contribute to the delivery of emergency medical services, particularly in rural areas and especially for more urgent calls. The work of community first responders has expanded from their original purpose-to attend to out-of-hospital cardiac arrests. The future development of community first responders' schemes should prioritize training for a range of conditions, and further research is needed to explore the contribution and potential future role of the community first responders from the perspective of service users, community first responders' schemes, ambulance services, and commissioners.

Effectiveness and cost-effectiveness of a personalised self-management intervention for living with long COVID: protocol for the LISTEN randomised controlled trial

BACKGROUND

Individuals living with long COVID experience multiple, interacting and fluctuating symptoms which can have a dramatic impact on daily living. The aim of the Long Covid Personalised Self-managemenT support EvaluatioN (LISTEN) trial is to evaluate effects of the LISTEN co-designed self-management support intervention for non-hospitalised people living with long COVID on participation in routine activities, social participation, emotional well-being, quality of life, fatigue, and self-efficacy. Cost-effectiveness will also be evaluated, and a detailed process evaluation carried out to understand how LISTEN is implemented.

METHODS

The study is a pragmatic randomised effectiveness and cost-effectiveness trial in which a total of 558 non-hospitalised people with long COVID will be randomised to either the LISTEN intervention or usual care. Recruitment strategies have been developed with input from the LISTEN Patient and Public Involvement and Engagement (PPIE) advisory group and a social enterprise, Diversity and Ability, to ensure inclusivity. Eligible participants can self-refer into the trial via a website or be referred by long COVID services. All participants complete a range of self-reported outcome measures, online, at baseline, 6 weeks, and 3 months post randomisation (the trial primary end point). Those randomised to the LISTEN intervention are offered up to six one-to-one sessions with LISTEN-trained intervention practitioners and given a co-designed digital resource and paper-based book. A detailed process evaluation will be conducted alongside the trial to inform implementation approaches should the LISTEN intervention be found effective and cost-effective.

DISCUSSION

The LISTEN trial is evaluating a co-designed, personalised self-management support intervention (the LISTEN intervention) for non-hospitalised people living with long COVID. The design has incorporated extensive strategies to minimise participant burden and maximise access. Whilst the duration of follow-up is limited, all participants are approached to consent for long-term follow-up (subject to additional funding being secured).

Examiner perceptions of the MRCGP recorded consultation assessment for general practice licensing during COVID-19: cross-sectional study

BACKGROUND

The Recorded Consultation Assessment (RCA) was developed rapidly during the COVID-19 pandemic to replace the Clinical Skills Assessment (CSA) for UK general practice licensing. Our aim was to evaluate examiner perceptions of the RCA.

METHODS

We employed a cross-sectional design using a questionnaire survey of RCA examiners with attitudinal (relating to examiners thoughts and perceptions of the RCA) and free text response options. We conducted statistical descriptive and factor analysis of quantitative data with qualitative thematic analysis of free text responses.

RESULTS

Overall, 182 of 260 (70%) examiners completed the questionnaire. Responders felt that consultations submitted were representative of the work of a typical GP during the pandemic and provided a good sample across the curriculum. They were also generally positive about the logistic, advisory and other support provided as well as the digital platform. Despite responders generally agreeing there was sufficient information available in video or audio consultations to judge candidates' data gathering, clinical management, and interpersonal skills, they were less confident about their ability to make judgments of candidates' performance compared with the CSA. The qualitative analysis of free text responses detailed the problems of case selection and content, explained examiners' difficulties when making judgments, and detailed the generally positive views about support, training and information technology. Responders also provided helpful recommendations for improving the assessment.

CONCLUSION

The RCA was considered by examiners to be feasible and broadly acceptable, although they experienced challenges from candidate case selection, case content and judgments leading to suggested areas for improvement.

Practitioners' views on community implementation of point-of-care ultrasound (POCUS) in the UK: a qualitative interview study

BACKGROUND

Implementing Point-of-care ultrasound (POCUS) in community practice could help to decide upon and prioritise initial treatment, procedures and appropriate specialist referral or conveyance to hospital. A recent literature review suggests that image quality, portability and cost of ultrasound devices are all improving with widening indications for community POCUS, but evidence about community POCUS use is needed in the UK. We aimed to explore views of clinical practitioners, actively using ultrasound, on their experiences of using POCUS and potential facilitators and barriers to its wider implementation in community settings in the UK.

METHODS

We conducted a qualitative interview study with practitioners from community and secondary care settings actively using POCUS in practice. A convenience sample of eligible participants from different clinical specialties and settings was recruited using social media adverts, through websites of relevant research groups and snowball sampling. Individual semi-structured interviews were conducted online using Microsoft Teams. These were recorded, transcribed verbatim, and analysed using a Framework approach supported by NVivo 12.

RESULTS

We interviewed 16 practitioners aged between 40 and 62 years from different professional backgrounds, including paramedics, emergency physicians, general practitioners, and allied health professionals. Participants identified key considerations and facilitators for wider implementation of POCUS in community settings in the UK: resource requirements for deployment and support of working devices; sufficient time and a skilled workforce; attention to training, education and support needs; ensuring proper governance, guidelines and quality assurance; workforce considerations; enabling ease of use in assisting decision making with consideration of unintended consequences; and more robust evidence to support perceptions of improved patient outcomes and experience.

CONCLUSIONS

POCUS could be useful for improving patient journey and health outcomes in community care, but this requires further research to evaluate outcomes. The facilitators identified could help make community POCUS a reality.

Common hierarchies, varied rules - the problem of governing community first responders in prehospital care for quality standards: documentary discourse analysis

A key focus is placed on engaging communities to become involved in making decisions to support health and care services in healthcare policies in England, UK. An example is the deployment of volunteers such as community first responders (CFRs), who are members of the public with basic life support skills, trained to intervene in emergency situations prior to the arrival of ambulance services. CFR policies have been devised by National Health Service (NHS) Trusts as a way of governing these and related activities. This paper critically examines the discourse around CFR policies to understand how CFR roles are organised and monitoring governance mechanisms are delineated in ensuring quality care delivery. We collected ten CFR policies from six ambulance services. Inductive analysis, guided by Foucault's theory, enabled the identification of themes and subthemes. We found that Trusts have a common goal to make care quality assurances to regulatory bodies on CFR roles, and this is depicted in common hierarchies of individual responsibilities across Trusts. However, policies that govern approaches to CFRs activity vary. Firstly, the paper highlights institutional approaches to ensuring public safety through the application of organised surveillance systems to monitor CFR activities, and draws parallels between such surveillance and Foucault's docile bodies. Secondly, the paper discusses how varying rules in the surveillance system compromises safety by decentralising knowledge to regulatory bodies to whom NHS Trusts must make safety assurances. We suggest that stronger interrelationships between Trusts in considering the CFR role has potential to increase public safety and outline a clearer direction for CFRs.

Optimising ambulance conveyance rates and staff costs by adjusting proportions of rapid-response vehicles and dual-crewed ambulances: an economic decision analytical modelling study

AIM

To model optimum proportions of dual-crewed ambulances (DCAs) and rapid-response vehicles (RRVs) in Ambulance Trusts with a view to generating a policy brief for one Ambulance Trust and a modelling tool for other Trusts on the strategic procurement and allocation of emergency vehicle (EV) resources.

METHODS

Historical EV assignments for 12 months of emergency calls in 2019 were provided by an NHS Ambulance Trust and analysed for backup, see and treat, and patient to hospital conveyance. Unit costs were derived for paramedics and technicians using Agenda for Change pay rates. Time cycles were assigned for RRV and DCA attendances and unit costs assigned to these. Information was put into a decision analytical model to estimate the costs and numbers of vehicles attending incidents based on relative proportions of available RRVs and DCAs.

RESULTS

Of 711 992 calls attended by 837 107 EVs, 514 766 (72.3%) required at least one emergency department conveyance. The rate of conveyance was significantly lower when RRVs arrived first on the scene. 27 883 out of 529 693 (5.3%) DCAs first arriving at an incident required some backup, and this was also factored into the model. Modelling demonstrated high conveyance rates were counterproductive when increasing the relative proportions of RRVs to DCAs. For example, with conveyance rates of 65%, increasing the RRVs increased the cost and numbers of vehicles attending per incident. At lower conveyance rates, however, there was a levelling around 30% where it could become cost-effective to increase the relative proportions of RRVs to DCAs.

CONCLUSION

At current overall conveyance rates, there is no benefit in increasing the relative proportions of RRVs to DCAs unless additional benefits can be realised that bring the conveyance rates down.

Time intervals and distances travelled for prehospital ambulance stroke care: data from the randomised-controlled ambulance-based Rapid Intervention with Glyceryl trinitrate in Hypertensive stroke Trial-2 (RIGHT-2)

OBJECTIVES

Ambulances offer the first opportunity to evaluate hyperacute stroke treatments. In this study, we investigated the conduct of a hyperacute stroke study in the ambulance-based setting with a particular focus on timings and logistics of trial delivery.

DESIGN

Multicentre prospective, single-blind, parallel group randomised controlled trial.

SETTING

Eight National Health Service ambulance services in England and Wales; 54 acute stroke centres.

PARTICIPANTS

Paramedics enrolled 1149 patients assessed as likely to have a stroke, with Face, Arm, Speech and Time score (2 or 3), within 4 hours of symptom onset and systolic blood pressure >120 mm Hg.

INTERVENTIONS

Paramedics administered randomly assigned active transdermal glyceryl trinitrate or sham.

PRIMARY AND SECONDARY OUTCOMES

Modified Rankin scale at day 90. This paper focuses on response time intervals, distances travelled and baseline characteristics of patients, compared between ambulance services.

RESULTS

Paramedics enrolled 1149 patients between September 2015 and May 2018.

FINAL DIAGNOSIS

intracerebral haemorrhage 13%, ischaemic stroke 52%, transient ischaemic attack 9% and mimic 26%. Timings (min) were (median (25-75 centile)): onset to emergency call 19 (5-64); onset to randomisation 71 (45-116); total time at scene 33 (26-46); depart scene to hospital 15 (10-23); randomisation to hospital 24 (16-34) and onset to hospital 97 (71-141). Ambulances travelled (km) 10 (4-19) from scene to hospital. Timings and distances differed between ambulance service, for example, onset to randomisation (fastest 53 min, slowest 77 min; p<0.001), distance from scene to hospital (least 4 km, most 20 km; p<0.001).

CONCLUSION

We completed a large prehospital stroke trial involving a simple-to-administer intervention across multiple ambulance services. The time from onset to randomisation and modest distances travelled support the applicability of future large-scale paramedic-delivered ambulance-based stroke trials in urban and rural locations.

Scaling-up a pharmacist-led information technology intervention (PINCER) to reduce hazardous prescribing in general practices: Multiple interrupted time series study

BACKGROUND

We previously reported on a randomised trial demonstrating the effectiveness and cost-effectiveness of a pharmacist-led information technology intervention (PINCER). We sought to investigate whether PINCER was effective in reducing hazardous prescribing when rolled out at scale in UK general practices.

METHODS AND FINDINGS

We used a multiple interrupted time series design whereby successive groups of general practices received the PINCER intervention between September 2015 and April 2017. We used 11 prescribing safety indicators to identify potentially hazardous prescribing and collected data over a maximum of 16 quarterly time periods. The primary outcome was a composite of all the indicators; a composite for indicators associated with gastrointestinal (GI) bleeding was also reported, along with 11 individual indicators of hazardous prescribing. Data were analysed using logistic mixed models for the quarterly event numbers with the appropriate denominator, and calendar time included as a covariate. PINCER was implemented in 370 (94.1%) of 393 general practices covering a population of almost 3 million patients in the East Midlands region of England; data were successfully extracted from 343 (92.7%) of these practices. For the primary composite outcome, the PINCER intervention was associated with a decrease in the rate of hazardous prescribing of 16.7% (adjusted odds ratio (aOR) 0.83, 95% confidence interval (CI) 0.80 to 0.86) at 6 months and 15.3% (aOR 0.85, 95% CI 0.80 to 0.90) at 12 months postintervention. The unadjusted rate of hazardous prescribing reduced from 26.4% (22,503 patients in the numerator/853,631 patients in the denominator) to 20.1% (11,901 patients in the numerator/591,364 patients in the denominator) at 6 months and 19.1% (3,868 patients in the numerator/201,992 patients in the denominator). The greatest reduction in hazardous prescribing associated with the intervention was observed for the indicators associated with GI bleeding; for the GI composite indicator, there was a decrease of 23.9% at both 6 months (aOR 0.76, 95% CI 0.73 to 0.80) and 12 months (aOR 0.76, 95% CI 0.70 to 0.82) postintervention. The unadjusted rate of hazardous prescribing reduced from 31.4 (16,185 patients in the numerator/515,879 patients in the denominator) to 21.2% (7,607 patients in the numerator/358,349 patients in the denominator) at 6 months and 19.5% (2,369 patients in the numerator/121,534 patients in the denominator). We adjusted for calendar time and practice, but since this was an observational study, the findings may have been influenced by unknown confounding factors or behavioural changes unrelated to the PINCER intervention. Data were also not collected for all practices at 6 months and 12 months postintervention.

CONCLUSIONS

The PINCER intervention, when rolled out at scale in routine clinical practice, was associated with a reduction in hazardous prescribing by 17% and 15% at 6 and 12 months postintervention. The greatest reductions in hazardous prescribing were for indicators associated with risk of GI bleeding. These findings support the wider national rollout of PINCER in England.

PP21 Factors affecting community first responders’ role in rural emergencies: a qualitative interview study

Background

Community first responders (CFRs) are volunteers delivering emergency medical assistance and maintaining a patient’s condition until an ambulance arrives. Previous research has highlighted the CFR role and relationships, motivations, practice and perceptions, and need for mental health support. However, factors influencing CFR practise in the field are a relatively underexplored area. We aimed to explore the factors embedded in CFR implementation processes that either facilitated or hindered CFRs’ activities and practice in the UK.

Method

In a qualitative study, we conducted interviews with CFRs and CFR leads, paramedics and ambulance clinicians, commissioners, patients and relatives across six English ambulance service regions. Thematic analysis, supported by NVivo, enabled the identification codes and themes.

Result

Overall, 47 participants were interviewed including CFR leads (15), CFRs (21), ambulance staff (4), and commissioners (2) from six ambulance services with patients and relatives (5) from the same regions. The findings revealed multi-layered factors influencing effective CFR functioning at three levels, namely individual, institutional, and societal. CFRs’ local expertise helped them to navigate operational challenges. Use of a personal vehicle and navigation software aided CFRs’ ability to respond promptly. Continuing training improved CFRs’ skills. CFR functioning was facilitated by positive relationships with ambulance crews. Identification and recognition by patients were important and aided by wearing uniforms. Community support was a facilitator for CFR activities in rural areas. In contrast, limited communication in remote regions, long waits for an ambulance, and reliance on community donations impeded CFRs’ care function. Volunteer shortages and lack of access to a blue light while using trusts’ car hindered CFRs’ ability to respond quickly. Negative relationships with ambulance crews also hampered CFRs’ involvement.

Conclusion

This study highlights factors associated with effective CFR functioning and the requirement for supportive institutional and societal contexts for CFRs to assist patients in medical emergencies.

04 People with diabetes and ambulance staff perceptions of a booklet-based intervention for diabetic hypoglycaemia, ‘hypos can strike twice’: a mixed methods process evaluation

Background

Hypoglycaemia is a potentially serious condition, characterised by lower-than-normal blood glucose levels, common in people with diabetes (PWD). It can be prevented and self-managed if expert support (e.g., education on lifestyle and treatment) is provided. Our aim was to conduct a process evaluation to investigate how ambulance staff and PWD perceived the ‘Hypos can strike twice’ booklet-based ambulance clinician intervention.

Methods

We used an explanatory sequential design with a self-administered questionnaire study followed by interviews of PWD and ambulance staff. We followed the Medical Research Council framework for process evaluations of complex interventions to guide data collection and analysis. Following descriptive analysis and exploratory factor analysis, multiple regression models were fitted to identify demographic predictors of overall and subscale scores.

Results

113 ambulance staff members and 46 PWD completed the survey. We conducted interviews with four ambulance staff members and five PWD who had been attended by an ambulance for a hypoglycaemic event. Overall, there were positive attitudes to the intervention from both ambulance staff and PWD. Although the intervention was not always implemented, most staff members and PWD found the booklet informative, easy to read and to use/explain. PWD who completed the survey reported that receiving the booklet reminded and/or encouraged them to test their blood glucose more often, adjust their diet, and have a chat/check up with their diabetes consultant. Interviewed PWD felt that the booklet intervention would be more valuable to less experienced patients or those who cannot manage their diabetes well. Participants felt that the intervention could be beneficial but were uncertain about whether it can prevent a second hypoglycaemic event and/or reduce the number of repeat ambulance attendances.

Conclusions

The ‘Hypos may strike twice’ intervention was found to be feasible, acceptable to PWD and staff, prompting reported behaviour change and help-seeking from primary care.

PP25 Activities and experiences of medical student first responders: a mixed methods study

Background

Medical Student First Responder (MSFR) schemes provide a Community First Responder (CFR) resource to their local ambulance Trust and experience for students. We aimed to investigate the contribution of these schemes and perceptions of students taking part in them.

Methods

In this convergent mixed methods study, we analysed dispatch data from two regional ambulance services and used propensity score matching to adjust for rurality and timing of attendance. MSFR attendances were compared with CFR and ambulance attendances. Multinomial logistic regression identified predictors of MSFR attendance compared with CFR and ambulance staff whilst accounting for confounders. We combined this with semistructured interviews of MSFRs from five schemes across the two regions. Interviews were transcribed verbatim and analysed using the Framework approach supported by NVivo. Final themes and categories were agreed through consensus.

Results

We included MSFR attendances from 2019 (n = 5817). MSFRs were more likely to attend urgent category 1 and 2 calls (vs ambulance category 3: RRR 4.67, 95%CI 3.08 - 7.07 or category 4: RRR 8.85, 95%CI 1.09 - 71.75) and cardiorespiratory (vs ambulance RRR 0.44, 95%CI 0.35 - 0.56) or neurological/endocrine calls (vs ambulance RRR 0.55, 95%CI 0.41 - 0.74). MSFRs were more likely, compared to CFRs and ambulance staff, to be dispatched to younger patients, those from ethnic minorities and deprived areas.

We interviewed 16 MSFRs from 5 medical schools. Participants described routes, requirements and challenges to recruitment. Training, mentorship, shadowing and debriefing were helpful to the role. Despite the risks and stress, most MSFRs enjoyed and valued their experience for enhancing clinical knowledge and skills in emergency care and understanding the wider context of care delivery. MSFRs’ experience also helped prepare for a future career involving emergency care.

Conclusions

MSFR schemes provide a valuable contribution to prehospital care and beneficial experiences for medical students.
