Referral pathways for TIA patients avoiding hospital admission : a scoping review

Objective: To identify the features and effects of a pathway for emergency assessment and referral of patients with suspected transient ischaemic attack (TIA) in order to avoid admission to hospital.Design: Scoping review.Data sources: PubMed, CINAHL Web of Science, Scopus.Study selection: Reports of primary research on referral of patients with suspected TIA directly to specialist outpatient services.Data extraction: We screened studies for eligibility and extracted data from relevant studies. Data were analysed to describe setting, assessment and referral processes, treatment, implementation and outcomes.Results: 8 international studies were identified, mostly cohort designs. 4 pathways were used by family doctors and 3 pathways by emergency department physicians. No pathways used by paramedics were found. Referrals were made to specialist clinic either directly or via a 24-hour helpline. Practitioners identified TIA symptoms and risk of further events using a checklist including the ABCD2 tool or clinical assessment. Antiplatelet medication was often given, usually aspirin unless contraindicated. Some patients underwent tests before referral and discharge. 5 studies reported reduced incident of stroke at 90 days, from 6–10% predicted rate to 1.3–2.1% actual rate. Between 44% and 83% of suspected TIA cases in these studies were referred through the pathways.Conclusions: Research literature has focused on assessment and referral by family doctors and ED physicians to reduce hospitalisation of patients with TIA. No pathways for paramedical use were reported. We will use results of this scoping review to inform development of a paramedical referral pathway to be tested in a feasibility trial

Use of scratchcards for allocation concealment in a prehospital randomised controlled trial

Background Rapid Analgesia for Prehospital Hip Disruption was a small study designed to determine the feasibility of undertaking a randomised controlled trial (RCT) to test the clinical and cost-effectiveness of paramedics administering Fascia Iliaca Compartment Block as early prehospital pain relief to patients with a fractured hip. The objective was to devise a simple and effective method of random allocation concealment suitable for use by paramedics while in the emergency prehospital setting. Methods Scratchcards were produced using scratch-off silver stickers which concealed the trial arm allocation. Paramedics were each allocated a unique range of consecutive numbers, used as both the scratchcard number and the patient’s study ID. The cards were designed to allow the paramedic to write on the incident number, date and signature. A small envelope holding the cards was prepared for each paramedic. The study took place between 28 June 2016 and 31 July 2017 in the Swansea area. Results Nineteen trial paramedics used 71 scratchcards throughout the study and reported no problems randomly allocating patients using the scratchcards. Five protocol deviations were reported in relation to scratchcard use. On auditing the scratchcards, all unused cards were located, and no evidence of tampering with the silver panel was found. Conclusion Paramedics can use scratchcards as a method of randomly allocating patients in trials in prehospital care. In the future, a method that allows only the top card to be selected and a more protective method of storing the cards should be used. Scratchcards can be considered for wider use in RCTs in the emergency prehospital setting

Paramedics' experiences of administering fascia iliaca compartment block to patients in South Wales with suspected hip fracture at the scene of injury: results of focus groups

Objectives To explore paramedics’ experience of delivering fascia iliaca compartment block (FICB) to patients with suspected hip fracture at the scene of injury. Design Focus groups within a randomised controlled trial. Setting Paramedics based at ambulance stations in the catchment area of one Emergency Department in South Wales, recruited and trained in a feasibility study about an alternative to routine prehospital pain management for patients with suspected hip fracture. Participants 11 paramedics. Intervention Paramedic-administered FICB to patients with suspected hip fracture. We randomly allocated eligible patients to FICB, a local anaesthetic injection directly into the hip region—or usual care, most commonly morphine - using audited scratch cards. Outcomes Paramedics’ experiences of administering FICB gathered through thematic analysis of interview transcripts by two researchers, one paramedic and one lay member. Results Respondents believed that FICB was a suitable intervention for paramedics to deliver. It aligned with routine practice and was within people’s capabilities. They said it took up to 10 minutes longer than usual care to prepare and deliver, in part due to nervousness and unfamiliarity with a new procedure. They praised the training provided but said they were anxious about causing harm by injecting into the wrong location. Confidence increased after one paramedic team successfully treated a patient for local anaesthetic toxicity. Reported challenges related to the emergency context: patients often waited many hours for ambulance arrival; moving patients exacerbated their pain; family and neighbours were present as paramedics administered treatment. Conclusions Paramedics are willing and able to administer FICB to patients with suspected hip fracture before ambulance transport to hospital. Feasibility study findings will inform further research

Prehospital recognition and antibiotics for 999 patients with sepsis: protocol for a feasibility study

Background: Sepsis is a common condition which kills between 36,000 and 64,000 people every year in the UK. Early recognition and management of sepsis has been shown to reduce mortality and improve the health and well-being of people with sepsis. Paramedics frequently come into contact with patients with sepsis and are well placed to provide early diagnosis and treatment. We aim to determine the feasibility of undertaking a fully powered randomised controlled trial (RCT) to test the clinical and cost-effectiveness of paramedics obtaining blood cultures from and administering IV antibiotics to patients with sepsis, so we can make a decision about whether to proceed to a fully powered randomised controlled trial, which will answer questions regarding safety and effectiveness for patients and benefit to the National Health Service (NHS). Methods/design: This is an individually randomised, two-arm feasibility study for a randomised controlled trial with a 1:1 ratio. Sixty paramedics will receive training to assist them to recognise sepsis using a screening tool, obtain blood cultures, and provide IV antibiotics. If sepsis is suspected, paramedics will randomly allocate patients to intervention or usual care using their next sequential individually issued scratch card. Patients will be followed up at 90 days using linked anonymised data to capture length of hospital admission and mortality. We will also collect self-reported health-related quality of life (using SF-12) at this time. We will interview ten patients by telephone and hold a focus group with paramedics, to find out what they think about the intervention. Discussion: At the end of this study, we will make a recommendation about whether a full randomised controlled trial of paramedics obtaining blood cultures and administering IV antibiotics for sepsis is warranted, and if so, we will develop a proposal for research funding in order to take the work forward
