Which elements of hospital-based clinical decision support tools for the assessment and management of children with head injury can be adapted for use by paramedics in prehospital care? A systematic mapping review and narrative synthesis.

OBJECTIVE: Hospital-based clinical decision tools support clinician decision-making when a child presents to the emergency department with a head injury, particularly regarding CT scanning. However, there is no decision tool to support prehospital clinicians in deciding which head-injured children can safely remain at scene. This study aims to identify clinical decision tools, or constituent elements, which may be adapted for use in prehospital care. DESIGN: Systematic mapping review and narrative synthesis. DATA SOURCES: Searches were conducted using MEDLINE, EMBASE, PsycINFO, CINAHL and AMED. ELIGIBILITY CRITERIA: Quantitative, qualitative, mixed-methods or systematic review research that included a clinical decision support tool for assessing and managing children with head injury. DATA EXTRACTION AND SYNTHESIS: We systematically identified all in-hospital clinical decision support tools and extracted from these the clinical criteria used in decision-making. We complemented this with a narrative synthesis. RESULTS: Following de-duplication, 887 articles were identified. After screening titles and abstracts, 710 articles were excluded, leaving 177 full-text articles. Of these, 95 were excluded, yielding 82 studies. A further 14 studies were identified in the literature after cross-checking, totalling 96 analysed studies. 25 relevant in-hospital clinical decision tools were identified, encompassing 67 different clinical criteria, which were grouped into 18 categories. CONCLUSION: Factors that should be considered for use in a clinical decision tool designed to support paramedics in the assessment and management of children with head injury are: signs of skull fracture; a large, boggy or non-frontal scalp haematoma neurological deficit; Glasgow Coma Score less than 15; prolonged or worsening headache; prolonged loss of consciousness; post-traumatic seizure; amnesia in older children; non-accidental injury; drug or alcohol use; and less than 1 year old. Clinical criteria that require further investigation include mechanism of injury, clotting impairment/anticoagulation, vertigo, length of time of unconsciousness and number of vomits.

Understanding paramedic work in general practice in the UK: a rapid realist synthesis.

BACKGROUND: General practice in the UK is under substantial pressure and practices are increasingly including paramedics as part of their workforce. Little is known about how different models of paramedic working may affect successful implementation of the role, as viewed from patient, clinician and system perspectives. This realist synthesis developed theories about 'models of paramedic working in general practice' in different UK contexts to understand their impact. METHODS: The rapid realist synthesis comprised data from: (1) empirical and grey literature searches; (2) semi-structured realist interviews with system leaders involved with the implementation of the role; and (3) a stakeholder event with healthcare professionals and the public, to develop initial programme theories that can be tested in future work. Sources were analysed using a realist approach that explored the data for novel or causal insights to generate initial programme theories. RESULTS: Empirical sources (n = 32), grey sources (n = 95), transcripts from system leader interviews (n = 7) and audio summaries from the stakeholder event (n = 22 participants) were synthesised into a single narrative document. The findings confirmed the presence of a wide variety of models of paramedic working in UK general practice. The perceived success of models was influenced by the extent to which the paramedic service was mature and embedded in practice, and according to four theory areas: (1) Primary care staff understanding and acceptance of the paramedic role; (2) Paramedic induction process, including access to training, supervision and development opportunities; (3) Patient understanding and acceptance of the role; (4) Variations in paramedic employment models. CONCLUSIONS: Variability in how the paramedic role is operating and embedding into general practice across the UK affects the success of the role. These findings provide a theoretical foundation for future research to investigate various 'models of paramedic working' in different contexts.

What factors are associated with ambulance use for non-emergency problems in children? A systematic mapping review and qualitative synthesis.

OBJECTIVE: To explore what factors are associated with ambulance use for non-emergency problems in children. METHODS: This study is a systematic mapping review and qualitative synthesis of published journal articles and grey literature. Searches were conducted on the following databases, for articles published between January 1980 and July 2020: MEDLINE, EMBASE, PsycINFO, CINAHL and AMED. A Google Scholar and a Web of Science search were undertaken to identify reports or proceedings not indexed in the above. Book chapters and theses were searched via the OpenSigle, EThOS and DART databases. A literature advisory group, including experts in the field, were contacted for relevant grey literature and unpublished reports. The inclusion criteria incorporated articles published in the English language reporting findings for the reasons behind why there are so many calls to the ambulance service for non-urgent problems in children. Data extraction was divided into two stages: extraction of data to generate a broad systematic literature 'map', and extraction of data from highly relevant papers using qualitative methods to undertake a focused qualitative synthesis. An initial table of themes associated with reasons for non-emergency calls to the ambulance for children formed the 'thematic map' element. The uniting feature running through all of the identified themes was the determination of 'inappropriateness' or 'appropriateness' of an ambulance call out, which was then adopted as the concept of focus for our qualitative synthesis. RESULTS: There were 27 articles used in the systematic mapping review and 17 in the qualitative synthesis stage of the review. Four themes were developed in the systematic mapping stage: socioeconomic status/geographical location, practical reasons, fear of consequences and parental education. Three analytical themes were developed in the qualitative synthesis stage including practicalities and logistics of obtaining care, arbitrary scoring system and retrospection. CONCLUSIONS: There is a lack of public and caregiver understanding about the use of ambulances for paediatrics. There are factors that appear specific to choosing ambulance care for children that are not so prominent in adults (fever, reassurance, fear of consequences). Future areas for attention to decrease ambulance activation for paediatric low-acuity reports were highlighted as: identifying strategies for helping caregivers to mitigate perceived risk, increasing availability of primary care, targeted education to particular geographical areas, education to first-time parents with infants and providing alternate means of transportation.

Exploring how paramedics are deployed in general practice and the perceived benefits and drawbacks: a mixed-methods scoping study.

BACKGROUND: General practice in the UK faces continuing challenges to balance a workforce shortage against rising demand. The NHS England GP Forward View proposes development of the multidisciplinary, integrated primary care workforce to support frontline service delivery, including the employment of paramedics. However, very little is known about the safety, clinical effectiveness, or cost-effectiveness of paramedics working in general practice. Research is needed to understand the potential benefits and drawbacks of this model of workforce organisation. AIM: To understand how paramedics are deployed in general practice, and to investigate the theories and drivers that underpin this service development. DESIGN & SETTING: A mixed-methods study using a literature review, national survey, and qualitative interviews. METHOD: A three-phase study was undertaken that consisted of: a literature review and survey; meetings with key informants (KIs); and direct enquiry with relevant staff stakeholders (SHs). RESULTS: There is very little evidence on the safety and cost-effectiveness of paramedics working in general practice and significant variation in the ways that paramedics are deployed, particularly in terms of the patients seen and conditions treated. Nonetheless, there is a largely positive view of this development and a perceived reduction in GP workload. However, some concerns centre on the time needed from GPs to train and supervise paramedic staff. CONCLUSION: The contribution of paramedics in general practice has not been fully evaluated. There is a need for research that takes account of the substantial variation between service models to fully understand the benefits and consequences for patients, the workforce, and the NHS.
