Abstract
Background Calls have been made for paramedics to have some form of care pathway that they could use to safely divert adults with epilepsy away from emergency departments and instigate ambulatory care improvements. Different configurations are possible. To know which to prioritise for implementation/evaluation, there is a need to determine which are acceptable to service users and likely National Health Service-feasible. Objective(s) (1) Identify configurations being considered, (2) understand service users' views of them and current provision, (3) identify what sort of care service users want and (4) determine which configuration(s) is considered to achieve optimal balance in meeting users' preference and being National Health Service-feasible. Design Service providers were surveyed to address objective 1. Interviews with service users addressed objective 2. Objective 3 was addressed by completing discrete choice experiments. These determined users' care preferences for different seizure scenarios. Objective 4 was addressed by completing 'knowledge exchange' workshops. At these, stakeholders considered the findings on users' stated preferences and judged different pathway configurations against Michie's 'acceptability, practicability, effectiveness, affordability, side-effects and equity' feasibility criteria. Setting This project took place in England. The survey recruited representatives from neurology and neuroscience centres and from urgent and emergency care providers. For the interviews, recruitment occurred via third-sector support groups. Recruitment for discrete choice experiments occurred via the North West Ambulance Service NHS Trust and public advert. Workshop participants were recruited from neurology and neuroscience centres, urgent and emergency care providers, support groups and commissioning networks. Participants Seventy-two services completed the survey. Interviews were conducted with 25 adults with epilepsy (and 5 relatives) who had emergency service contact in the prior 12 months. Discrete choice experiments were completed by 427 adults with epilepsy (and 167 relatives) who had ambulance service contact in the prior 12 months. Workshops were completed with 27 stakeholders. Results The survey identified a range of pathway configurations. They differed in where they would take the patient and their potential to instigate ambulatory care improvements. Users had been rarely consulted in designing them. The discrete choice experiments found that users want a configuration of care markedly different to that offered. Across the seizure scenarios, users wanted their paramedic to have access to their medical records; for an epilepsy specialist (e.g. an epilepsy nurse, neurologist) to be available to advise; for their general practitioner to receive a report; for the incident to generate an appointment with an epilepsy specialist; for the care episode to last < 6 hours; and there was a pattern of preference to avoid conveyance to emergency departments and stay where they were. Stakeholders judged this configuration to be National Health Service-feasible within 5-10 years, with some elements being immediately deployable. Limitations The discrete choice experiment sample was broadly representative, but those reporting recent contact with an epilepsy specialist were over-represented. Conclusions Users state they want a configuration of care that is markedly different to current provision. The configuration they prefer was, with support and investment, judged to likely be National Health Service-feasible. The preferred configuration should now be developed and evaluated to determine its actual deliverability and efficacy. Study registration The study is registered as researchregistry4723.

Service users' preferences and feasibility - which alternative care pathway for adult ambulance users achieves the optimal balance? Workshops for the COLLABORATE project. Seizure 2024; 118:17-27. [PMID: 38613878 DOI: 10.1016/j.seizure.2024.04.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 04/08/2024] [Accepted: 04/10/2024] [Indexed: 04/15/2024] Open
Abstract
INTRODUCTION Adults presenting to the ambulance service for diagnosed epilepsy are often transported to emergency departments (EDs) despite no clinical need. An alternative care pathway (CP) could allow paramedics to divert them from ED and instigate ambulatory care improvements. To identify the most promising CP configuration for subsequent testing, the COLLABORATE project surveyed people with epilepsy and family/friends who had recently used the English ambulance service to elicit preferences for 288 CP configurations for different seizures. This allowed CPs to be ranked according to alignment with service users' preferences. However, as well as being acceptable to users, a CP must be feasible. We thus engaged with paramedics, epilepsy specialists and commissioners to identify the optimal configuration. METHODS Three Knowledge Exchange workshops completed. Participants considered COLLABORATE's evidence on service users' preferences for the different configurations. Nominal group techniques elicited views on the feasibility of users' preferences according to APEASE criteria. Workshop groups specified the configuration/s considered optimum. Qualitative data was analysed thematically. Utility to users of the specified CP configurations estimated using the COLLABORATE preference survey data. RESULTS Twenty-seven participants found service users' preferences broadly feasible and outlined delivery recommendations. They identified enough commonality in preferences for different seizures to propose a single CP. Its configuration comprised: 1) patients staying where they were; 2) paramedics having access to medical records; 3) care episodes lasting <6 h; 4) paramedics receiving specialist advice on the day; 5) patient's GP being notified; and 6) a follow-up appointment being arranged with an epilepsy specialist. Preference data indicated higher utility for this configuration compared to current care. DISCUSSION Stakeholders are of the view that the CP configuration favoured by service users could be NHS feasible. It should be developed and evaluated.

[PMID: 38615478 DOI: 10.1016/j.seizure.2024.04.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 04/03/2024] [Accepted: 04/09/2024] [Indexed: 04/16/2024] Open
Abstract
INTRODUCTION To identify service users' preferences for an alternative care pathway for adults with epilepsy presenting to the ambulance service. METHODS Extensive formative work (qualitative, survey and knowledge exchange) informed the design of a stated preference discrete choice experiment (DCE). This hypothetical survey was hosted online and consisted of 12 binary choices of alternative care pathways described in terms of: the paramedic's access to medical records/ 'care plan', what happens next (described in terms of conveyance), time, availability of epilepsy specialists today, general practitioner (GP) notification and future contact with epilepsy specialists. DCE scenarios were described as: (i) typical seizure at home. (ii) typical seizure in public, (iii) atypical seizure. Respondents were recruited by a regional English ambulance service and by national public adverts. Participants were randomised to complete 2 of the 3 DCEs. RESULTS People with epilepsy (PWE; n = 427) and friends/family (n = 167) who completed the survey were representative of the target population. PWE preferred paramedics to have access to medical records, non-conveyance, to avoid lengthy episodes of care, availability of epilepsy specialists today, GP notification, and contact with epilepsy specialists within 2-3 weeks. Significant others (close family members or friends) preferred PWE experiencing an atypical seizure to be conveyed to an Urgent Treatment Centre and preferred shorter times. Optimal configuration of services from service users' perspective far out ranked current practice (rank 230/288 possible configurations). DISCUSSION Preferences differ to current practice but have minimal variation by seizure type or stakeholder. Further work on feasibility of these pathways in England, and potentially beyond, is required.

'Knowledge exchange' workshops to optimise development of a risk prediction tool to assist conveyance decisions for suspected seizures - Part of the Risk of ADverse Outcomes after a Suspected Seizure (RADOSS) project. Epilepsy Behav 2024; 151:109611. [PMID: 38199055 DOI: 10.1016/j.yebeh.2023.109611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 12/21/2023] [Accepted: 12/22/2023] [Indexed: 01/12/2024]
Abstract
PURPOSE Suspected seizures present challenges for ambulance services, with paramedics reporting uncertainty over whether or not to convey individuals to emergency departments. The Risk of ADverse Outcomes after a Suspected Seizure (RADOSS) project aims to address this by developing a risk assessment tool utilizing structured patient care record and dispatch data. It proposes a tool that would provide estimates of an individual's likelihood of death and/or recontact with emergency care within 3 days if conveyed compared to not conveyed, and the likelihood of an 'avoidable attendance' occurring if conveyed. Knowledge Exchange workshops engaged stakeholders to resolve key design uncertainties before model derivation. METHOD Six workshops involved 26 service users and their significant others (epilepsy or nonepileptic attack disorder), and 25 urgent and emergency care clinicians from different English ambulance regions. Utilizing Nominal Group Techniques, participants shared views of the proposed tool, benefits and concerns, suggested predictors, critiqued outcome measures, and expressed functionality preferences. Data were analysed using Hamilton's Rapid Analysis. RESULTS Stakeholders supported tool development, proposing 10 structured variables for predictive testing. Emphasis was placed on the tool supporting, not dictating, care decisions. Participants highlighted some reasons why RADOSS might struggle to derive a predictive model based on structured data alone and suggested some non-structured variables for future testing. Feedback on prediction timeframes for service recontact was received, along with advice on amending the 'avoidable attendance' definition to prevent the tool's predictions being undermined by potential overuse of certain investigations in hospital. CONCLUSION Collaborative stakeholder engagement provided crucial insights that can guide RADOSS to develop a user-aligned, optimized tool.

A cross-sectional survey of student paramedics on how well they perceive their UK pre-registration course to be preparing them to manage suspected seizures. BMC Emerg Med 2023; 23:119. [PMID: 37807077 PMCID: PMC10561511 DOI: 10.1186/s12873-023-00889-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Accepted: 09/25/2023] [Indexed: 10/10/2023] Open
Abstract
BACKGROUND Paramedics convey a high proportion of seizure patients with no clinical need to emergency departments (EDs). In a landmark study, only 27% of UK paramedics reported being "Very…"/ "Extremely confident" making seizure conveyance decisions. Improved pre-registration education on seizures for paramedics is proposed. Clarity is needed on its potential given recent changes to how UK paramedics train (namely, degree, rather than brief vocational course). This study sought to describe UK student paramedics' perceived readiness to manage seizures and educational needs; compare this to what they report for other presentations; and, explore subgroup differences. METHODS Six hundred thirty-eight students, in year 2 or beyond of their pre-registration programme completed a cross-sectional survey. They rated perceived confidence, knowledge, ability to care for, and educational needs for seizures, breathing problems and, headache. Primary measure was conveyance decision confidence. RESULTS For seizures, 45.3% (95% CI 41.4-49.2) said they were "Very…"/"Extremely confident" to make conveyance decisions. This was similar to breathing problems, but higher than for headache (25.9%, 95% CI 22.6-29.5). Two hundred and thirty-nine participants (37.9%, 95% CI 34.1-41.8) said more seizure education was required - lower than for headache, but higher than for breathing problems. Subgroup differences included students on university-based programmes reporting more confidence for conveyance decisions than those completing degree level apprenticeships. CONCLUSIONS Student paramedics report relatively high perceived readiness for managing seizures. Magnitude of benefit from enhancements to pre-registration education may be more limited than anticipated. Additional factors need attention if a sizeable reduction to unnecessary conveyances for seizures is to happen.

Abstract
BACKGROUND Information for treatment or hospital derivation of prehospital seizures is limited, impairing patient condition and hindering patients risk assessment by the emergency medical services (EMS). This study aimed to determine the associated factors to clinical impairment, and secondarily, to determine risk factors associated to cumulative in-hospital mortality at 2, 7 and 30 days, in patients presenting prehospital seizures. METHODS Prospective, multicentre, EMS-delivery study involving adult subjects with prehospital seizures, including five advanced life support units, 27 basic life support units and four emergency departments in Spain. All bedside variables: including demographic, standard vital signs, prehospital laboratory tests and presence of intoxication or traumatic brain injury (TBI), were analysed to construct a risk model using binary logistic regression and internal validation methods. RESULTS A total of 517 patients were considered. Clinical impairment was present in 14.9%, and cumulative in-hospital mortality at 2, 7 and 30-days was 3.4%, 4.6% and 7.7%, respectively. The model for the clinical impairment indicated that respiratory rate, partial pressure of carbon dioxide, blood urea nitrogen, associated TBI or stroke were risk factors; higher Glasgow Coma Scale (GCS) scores mean a lower risk of impairment. Age, potassium, glucose, prehospital use of mechanical ventilation and concomitant stroke were risk factors associated to mortality; and oxygen saturation, a high score in GCS and haemoglobin were protective factors. CONCLUSION Our study shows that prehospital variables could reflect the clinical impairment and mortality of patients suffering from seizures. The incorporation of such variables in the prehospital decision-making process could improve patient outcomes.

Abstract
BACKGROUND To prioritize emergency medical calls for ambulance transport for patients with suspected seizures, information about whether the event is their 1st or non-1st seizure is important. However, little is known about the difference between 1st and non-1st seizures in terms of severity. We hypothesized that patients transferred multiple times (≥2 times) would represent a milder scenario than patients on their first transfer. The purpose of this study was to compare patients with suspected seizures on 1st transfer by ambulance and patients who had been transferred ≥2 times. METHODS We statistically compared severity of suspected seizures between two groups of patients with suspected seizures transferred between December 2014 and November 2019 (before the coronavirus disease 2019 pandemic) to our facility by ambulance for either the first time (1st Group) or at least the second time (Non-1st Group). Severity categories were defined as: Level 1 = life-threatening; Level 2 = emergent, needing admission to the intensive care unit; Level 3 = urgent, needing admission to a hospital general ward; Level 4 = less urgent, needing intervention but not hospitalization; and Level 5 = non-urgent, not needing intervention. RESULTS Among 5996 patients with suspected seizures conveyed to the emergency department by ambulance a total of 14,263 times during the study period, 1222 times (8.6%) and 636 patients (11%) met the criteria. Severity grade of suspected seizures ranged from 1 to 5 (median, 4; interquartile range, 3-4) for the 1st Group and from 1 to 5 (median, 5; interquartile range, 4-5) for the Non-1st Group. Most severe grade ranged from 1 to 5 (median, 4; interquartile range, 4-5) for the Non-1st Group. Severity grade differed significantly between groups (p < 0.001, Mann-Whitney U-test). Uni- and multivariate logistic regression tests also suggested a significant difference (p < 0.001) in severity grades. CONCLUSION In direct comparisons, grade of suspected seizure severity was lower in the Non-1st Group than in the 1st Group.

Abstract
INTRODUCTION Ambulances services are asked to further reduce avoidable conveyances to emergency departments (EDs). Risk of Adverse Outcomes after a Suspected Seizure seeks to support this by: (1) clarifying the risks of conveyance and non-conveyance, and (2) developing a risk prediction tool for clinicians to use 'on scene' to estimate the benefits an individual would receive if conveyed to ED and risks if not. METHODS AND ANALYSIS Mixed-methods, multi-work package (WP) project. For WP1 and WP2 we shall use an existing linked data set that tracks urgent and emergency care (UEC) use of persons served by one English regional ambulance service. Risk tools are specific to clinical scenarios. We shall use suspected seizures in adults as an exemplar.WP1: Form a cohort of patients cared for a seizure by the service during 2019/2020. It, and nested Knowledge Exchange workshops with clinicians and service users, will allow us to: determine the proportions following conveyance and non-conveyance that die and/or recontact UEC system within 3 (/30) days; quantify the proportion of conveyed incidents resulting in 'avoidable ED attendances' (AA); optimise risk tool development; and develop statistical models that, using information available 'on scene', predict the risk of death/recontact with the UEC system within 3 (/30) days and the likelihood of an attendance at ED resulting in an AA.WP2: Form a cohort of patients cared for a seizure during 2021/2022 to 'temporally' validate the WP1 predictive models.WP3: Complete the 'next steps' workshops with stakeholders. Using nominal group techniques, finalise plans to develop the risk tool for clinical use and its evaluation. ETHICS AND DISSEMINATION WP1a and WP2 will be conducted under database ethical approval (IRAS 307353) and Confidentiality Advisory Group (22/CAG/0019) approval. WP1b and WP3 have approval from the University of Liverpool Central Research Ethics Committee (11450). We shall engage in proactive dissemination and knowledge mobilisation to share findings with stakeholders and maximise evidence usage.

[PMID: 35760830 PMCID: PMC9237077 DOI: 10.1038/s41598-022-15115-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 06/17/2022] [Indexed: 12/02/2022] Open
Abstract
Seizures are a common reason for calling emergency medical services. A lack of guidelines on prehospital treatment in Germany leads to high transportation rates and reduced confidence in decision making by professionals. Our aim was to investigate the reasons for hospitalization and evaluate their necessity. A retrospective analysis of all emergency medical services records in Munich, Germany was performed in order to examine the reasons for hospitalization of patients with seizures and to evaluate their trajectory following admission to a university hospital. 8882 records were analyzed with 415 records reporting seizures (4.9%). Primary endpoint was transportation to hospital. In 380 cases (92%) patients were transported, of which 177 patients (47%) had known epilepsy; 35 patients (8%) were left at scene. Older patients and patients with higher amounts of administered medication at the scene were hospitalized significantly more often (p = 0.032 and p = 0.004, respectively). Median hospital length of stay was 1 night [IQR 1–2]. In patients with out-of-hospital seizures, high hospital transportation rates were evident, most of which could be considered as not indicated. One possible reason is the lack of guidelines in Germany, which leads to uncertainty among medical staff. This results in distress for the patients, their caregivers and consequently high costs.

Emerg Med J 2022; 39:608-615. [PMID: 35078857 DOI: 10.1136/emermed-2021-211735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Accepted: 01/08/2022] [Indexed: 11/03/2022]
Abstract
BACKGROUND Paramedics are frequently called to attend seizures in children. High-quality evidence on second-line treatment of benzodiazepine (BZD)-refractory convulsions with parenteral long-acting antiepileptic drugs in children has become available from the ED. In order to address the potential need for an alternative agent, we set out to determine the association of BZD use prehospital and the need for respiratory support. METHODS We conducted a retrospective observational study of state-wide ambulance service data (Ambulance Victoria in Victoria, Australia, population: 6.5 million). Children aged 0-17 years assessed for seizures by paramedics were analysed for demographics, process factors, treatment and airway management. We calculated adjusted ORs (AOR) of the requirement for respiratory support in relation to the number of BZD doses administered. RESULTS Paramedics attended 5112 children with suspected seizures over 1 year (1 July 2018 to 30 June 2019). Overall, need for respiratory support was low (n=166; 3.2%). Before ambulance arrival, 509 (10.0%) had already received a BZD and 420 (8.2%) were treated with midazolam by paramedics. Of the 846 (16.5%) patients treated with BZD, 597 (70.6%) received 1 BZD dose, 156 (18.4%) 2 doses and 93 (11.0%) >2 doses of BZD. Patients who were administered 1, 2 and >2 doses of BZD received respiratory support in 8.9%, 32.1% (AOR 4.6 vs 1 dose, 95% CI 2.9 to 7.4) and 49.5% (AOR 10.3 vs 1 dose, 95% CI 6.0 to 17.9), respectively. CONCLUSIONS Increasing administration of BZD doses was associated with higher use of respiratory support. Alternative prehospital antiepileptic drugs to minimise respiratory depression should be investigated in future research.

Oro-mucosal midazolam maleate: Use and effectiveness in adults with epilepsy in the UK. Epilepsy Behav 2021; 123:108242. [PMID: 34371288 DOI: 10.1016/j.yebeh.2021.108242] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 07/14/2021] [Accepted: 07/24/2021] [Indexed: 01/22/2023]
Abstract
BACKGROUND Oro-mucosal midazolam maleate (OMM) with suitable training to family and carers is being increasingly recognized as the treatment of choice to mitigate the development of status epilepticus in non-hospital community settings. There are no studies to describe the use, effectiveness, and suitable dosing of OMM in adults with epilepsy in community settings. PURPOSE To describe the use, effectiveness, and dosing of OMM in the emergency treatment of epileptic seizures in community settings. METHODS A retrospective observational study (2016-17) design was used with participant recruitment from four UK NHS secondary care outpatient clinics providing epilepsy management. Study sample was of adult people with epilepsy (PWE) having had a recent seizure requiring OMM. Data on patient demographics, patient care plans, details of a recent seizure requiring emergency medication, and dose of OMM were collected from medical records. RESULTS Study data from 146 PWE were included. The mean age of PWE was 41.0 years (SD 15.2) and mean weight was 64.8Kg (SD 18.2). Fifty-three percent of PWE were recorded as having intellectual disability. The most frequently used concomitant medications were lamotrigine (43%). The majority of seizures occurred at people's homes (n = 92, 63%). OMM was most often administered by family/professional care-givers (n = 75, 48.4%). Generalized (tonic/clonic) seizures were recorded in most people (n = 106, 72.6%). The most common initial dose of OMM was 10 mg (n = 124, 84.9%). The mean time to seizure cessation after administration of this initial dose was 5.5 minutes (SD = 4.5, Median 5.0, IQR 2.1-5.0). Only a minority of seizures led to ambulance callouts (n = 18, 12.3%) or hospital admissions (n = 13, 9%). CONCLUSION This is the first observational study describing the use and effectiveness of OMM in adults in community settings. Minimal hospital admissions were reported in this cohort and the treatment was effective in ending seizures in adults in community settings.

Abstract
OBJECTIVES We aimed to estimate the rate of psychogenic nonepileptic seizures (PNES) among patients presenting to an emergency department with presumed seizures. We also wanted to identify factors that can assist health care professionals in determining whether these events are likely to be epileptic or nonepileptic. METHODS We performed two retrospective audits on patients who were treated for seizures in the department of emergency medicine at the Princess Alexandra Hospital, Brisbane, Australia. Exploratory analyses and logistic regressions were conducted to investigate the characteristics of the presentations and the relationships between our variables of interest. RESULTS In the group of all presentations with presumed seizures over a 3-month period (n = 157), a total of 151 presentations (96.2%) presentations were given a primary diagnosis of epileptic seizures. Of these 151 presentations, only 84 (55.6%) presented with epileptic seizures and 40 (26.5%) actually presented with PNES. In the group of patients who presented with prolonged and/or multiple events (n = 213) over a 1-year period, 196 (92.0%) were treated as epileptic seizures. Of these 196 presentations, only 85 (43.4%) presented with epileptic seizures and 97 (49.5%) actually presented with PNES. Several factors were identified to help risk stratify between epileptic seizures and PNES: Duration of events and of the postictal phase, number of events, presence of a structural brain pathology, mental health history, lactate levels and presence of tongue bite, incontinence, and/or vomiting. SIGNIFICANCE A large proportion of people who present to emergency departments with events resembling epileptic seizures actually have PNES rather than epilepsy-particularly those patients who present with prolonged and/or multiple events. The rate of misdiagnosis was high. Efforts need to be made to recognize patients with psychogenic nonepileptic seizures earlier and diagnose them correctly to avoid unnecessary iatrogenic harm and to provide adequate treatment.

Abstract
BACKGROUND Generalized convulsive status epilepticus (GCSE) is a neurologic emergency demanding prehospital identification and treatment. Evaluating real-world practice requires accurately identifying the target population; however, it is unclear whether emergency medical services (EMS) documentation accurately identifies patients with GCSE. OBJECTIVE To evaluate the validity of EMS diagnostic impressions for GCSE. METHODS This was an analysis of electronic medical records of a California county EMS system from 2013 to 2018. We identified all cases with a primary diagnostic impression of "seizure-active," "seizure-post," or "seizure-not otherwise specified (NOS)" and within each diagnostic category, we randomly selected 75 adult and 25 pediatric records. Two authors reviewed the provider narrative of these 300 charts to determine a clinical seizure diagnosis according to prespecified definitions. We calculated a kappa for interrater reliability of the clinical diagnosis. We then calculated the positive predictive value (PPV), sensitivity, and specificity of an EMS diagnosis of "seizure-active" diagnosis for identifying GCSE. Sensitivity and specificity calculations were weighted according to the distribution of seizure cases in the overall population. We performed a descriptive analysis of records with an incorrect EMS diagnosis of GCSE or seizure. RESULTS Of 38,995 total records for seizure, there were 3401 (8.7%) seizure-active cases, 12,478 (32.0%) seizure-NOS cases, and 23,116 (59.4%) seizure-post cases. An EMS diagnosis of "seizure-active" had a PPV of 65.0% (95% CI 54.8-74.3), sensitivity of 54.6% (95% confidence interval [CI] 39.3-69.0), and specificity of 96.6% (95% CI 95.1-97.6) for capturing GCSE. Limiting the case definition to patients who received an EMS diagnosis of "seizure-active" and were treated with a benzodiazepine increased the PPV (80.2%; 95% CI 69.9-88.2) and specificity (99.3%; 95% CI 98.7-99.6) while the sensitivity decreased (25.1%; 95% CI 17.0-35.3). Across the 300 records reviewed, there were 19 (6.3%) patients who had a non-seizure related diagnosis including non-epileptic spells (7 records), altered mental status (8 records), tremors (2 records), anxiety (1 record), and stroke (1 record). CONCLUSIONS EMS diagnostic impressions have reasonable PPV and specificity but low sensitivity for GCSE. Improved coding algorithms and training will allow for improved benchmarking, quality improvement, and research about this neurologic emergency.

Seizure first aid training for people with epilepsy attending emergency departments and their significant others: the SAFE intervention and feasibility RCT.

Abstract
Background
No seizure first aid training intervention exists for people with epilepsy who regularly attend emergency departments and their significant others, despite such an intervention’s potential to reduce clinically unnecessary and costly visits.
Objectives
The objectives were to (1) develop Seizure first Aid training For Epilepsy (SAFE) by adapting a broader intervention and (2) determine the feasibility and optimal design of a definitive randomised controlled trial to test SAFE’s efficacy.
Design
The study involved (1) the development of an intervention informed by a co-design approach with qualitative feedback and (2) a pilot randomised controlled trial with follow-ups at 3, 6 and 12 months and assessments of treatment fidelity and the cost of SAFE’s delivery.
Setting
The setting was (1) third-sector patient support groups and professional health-care organisations and (2) three NHS emergency departments in England.
Participants
Participants were (1) people with epilepsy who had visited emergency departments in the prior 2 years, their significant others and emergency department, paramedic, general practice, commissioning, neurology and nursing representatives and (2) people with epilepsy aged ≥ 16 years who had been diagnosed for ≥ 1 year and who had made two or more emergency department visits in the prior 12 months, and one of their significant others. Emergency departments identified ostensibly eligible people with epilepsy from attendance records and patients confirmed their eligibility.
Interventions
Participants in the pilot randomised controlled trial were randomly allocated 1 : 1 to SAFE plus treatment as usual or to treatment as usual only.
Main outcome measures
Consent rate and availability of routine data on emergency department use at 12 months were the main outcome measures. Other measures of interest included eligibility rate, ease with which people with epilepsy could be identified and routine data secured, availability of self-reported emergency department data, self-reported emergency department data’s comparability with routine data, SAFE’s effect on emergency department use, and emergency department use in the treatment as usual arm, which could be used in sample size calculations.
Results
(1) Nine health-care professionals and 23 service users provided feedback that generated an intervention considered to be NHS feasible and well positioned to achieve its purpose. (2) The consent rate was 12.5%, with 53 people with epilepsy and 38 significant others recruited. The eligibility rate was 10.6%. Identifying people with epilepsy from attendance records was resource intensive for emergency department staff. Those recruited felt more stigmatised because of epilepsy than the wider epilepsy population. Routine data on emergency department use at 12 months were secured for 94.1% of people with epilepsy, but the application process took 8.5 months. Self-reported emergency department data were available for 66.7% of people with epilepsy, and people with epilepsy self-reported more emergency department visits than were captured in routine data. Most participants (76.9%) randomised to SAFE received the intervention. The intervention was delivered with high fidelity. No related serious adverse events occurred. Emergency department use at 12 months was lower in the SAFE plus treatment as usual arm than in the treatment as usual only arm, but not significantly so. Calculations indicated that a definitive trial would need ≈ 674 people with epilepsy and ≈ 39 emergency department sites.
Limitations
Contrary to patient statements on recruitment, routine data secured at the pilot trial’s end indicated that ≈ 40% may not have satisfied the inclusion criterion of two or more emergency department visits.
Conclusions
An intervention was successfully developed, a pilot randomised controlled trial conducted and outcome data secured for most participants. The consent rate did not satisfy a predetermined ‘stop/go’ level of ≥ 20%. The time that emergency department staff needed to identify eligible people with epilepsy is unlikely to be replicable. A definitive trial is currently not feasible.
Future work
Research to more easily identify and recruit people from the target population is required.
Trial registration
Current Controlled Trials ISRCTN13871327.

Abstract
INTRODUCTION The urgent and emergency care (UEC) system is struggling with increased demand, some of which is clinically unnecessary. Patients suffering suspected seizures commonly present to EDs, but most seizures are self-limiting and have low risk of short-term adverse outcomes. We aimed to investigate the flow of suspected seizure patients through the UEC system using data linkage to facilitate the development of new models of care. METHODS We used a two-stage process of deterministic linking to perform a cross-sectional analysis of data from adults in a large region in England (population 5.4 million) during 2014. The core dataset comprised a total of 739 436 ambulance emergency incidents, 1 033 778 ED attendances and 362 358 admissions. RESULTS A high proportion of cases were successfully linked (86.9% ED-inpatient, 77.7% ED-ambulance). Suspected seizures represented 2.8% of all ambulance service incidents. 61.7% of these incidents led to dispatch of a rapid-response ambulance (8 min) and 72.1% were conveyed to hospital. 37 patients died before being conveyed to hospital and 24 died in the ED (total 61; 0.3%). The inpatient death rate was 0.4%. Suspected seizures represented 0.71% of ED attendances, 89.8% of these arrived by emergency ambulance, 45.4% were admitted and 44.5% of these admissions lasted under 48 hours. CONCLUSIONS This study confirms previously published data from smaller unlinked datasets, validating the linkage method, and provides new data for suspected seizures. There are significant barriers to realising the full potential of data linkage. Collaborative action is needed to create facilitative governance frameworks and improve data quality and analytical capacity.

Abstract
PURPOSE Emergency Department (ED) visits are costly to the health service and alternative care pathways may address this whilst improving outcomes. We aimed to describe decision-making and preferences of people with epilepsy (PWE) during emergency service use, and views of ED alternatives, including use of an Urgent Treatment Centre and telephone-based support from an epilepsy nurse specialist. METHODS We conducted a community-based interview study in South East England, informed by a qualitative framework approach. 25 adults with epilepsy and 5 of their carers took part. RESULTS Participants' choice to attend ED generally corresponded with guidelines, including continuing seizures and injury. Nevertheless, over half reported unwanted or unnecessary ED attendance, mainly due to lack of access to individual patient history, a carer, or seizures occurring in a public place. Participants used proactive strategies to communicate their care needs to others, including 24 -h alarm devices and care plans. Some suggested preventative strategies including referral after ED. Participants highlighted the importance of ambulance staff in providing fast and efficient care that gives reassurance. CONCLUSION Improving communication and access to preventative, proactive services may facilitate better outcomes within existing care pathways. PWE felt ED alternatives were helpful in some circumstances, but Urgent Treatment Centres or epilepsy nurse specialists were not viewed as an ED replacement.

Abstract
Background: One of the most frequent complaints that emergency medical services (EMS) deal with is seizure. The missions of EMS on these cases may lead to transferring the patient to the emergency department (ED). Objectives: Therefore, the present study was conducted to compare the short-term outcome of transported versus not-transported cases. Methods: Our population sample was selected retrospectively from medical records in Tehran EMS center for 6 months in which the plan was transferring to a specific hospital. The cases were divided into transported or not-transported. W extracted and compared the cases’ demographic data, vital signs, conducted prehospital management, patient disposition, and their short-term outcome. Results: We evaluated 486 cases, 173 of whom were males (35.6%) and the mean age of patients was 34.8 ± 32.0 years old. 329 (67.7%) and 157 (32.3%) were in the not-transported and the transported group, respectively. Among all not-transported cases, we could follow 172 patients, 52 of whom had gone to hospital during the next 72 hours. 22 out of the 52 cases were discharged from ED the same day. Overall, the ED discharge rate was significantly more in the transported group (P < 0.001). Short-term mortality had no significant difference in the two study groups (P = 1.00). Conclusions: Most of the not-transported patients did not go to the hospital during further 72 hours, and some were hospitalized. Most of the patients transported to the hospital were discharged from the ED. The short-term mortality rate was not different.

A survey of general practitioner's opinion on the proposal to introduce 'treat and referral' into the Irish emergency medical service. Ir J Med Sci 2020; 189:1457-1463.

Abstract
BACKGROUND The introduction of treat and referral by ambulance practitioners is under active consideration in Ireland. The Irish ambulance services have traditionally transported all patients following an emergency (112/999) call to an emergency department. The introduction of treat and referral will present a significant care pathway change. AIMS To engage GPs in relation to the proposed introduction of treat and referral. METHODS A postal survey of 50 general practices in the southeast of Ireland was completed in 2019 to identify their opinion on the introduction of treat and referral. Descriptive statistics were calculated, and Pearson's chi-square tests were used to identify statistically significant differences among GP cohorts. RESULTS A 78% response rate was achieved. Respondents indicated that informal treat and referral was practised by 40% of GPs. A significant majority of GPs indicated that their patients with diabetes or epilepsy would benefit from treat and referral and were happy for paramedics to make appointments posthypoglycaemia or seizure. There was no clear consensus in relation to confining treat and referral to adults only. Barriers to the implementation of treat and referral were a significant issue for GPs. CONCLUSIONS GPs are in the main supportive of the introduction of treat and referral; however, they have identified several barriers that may inhibit successful introduction. Importantly, a GP appointment within 48 h does not appear to be a barrier. The adequacy of the working relationships between GPs and the ambulance service and its practitioners appears to have reduced since 2006, which is concerning.

OBJECTIVE To determine the feasibility and optimal design of a randomised controlled trial (RCT) of Seizure First Aid Training For Epilepsy (SAFE). DESIGN Pilot RCT with embedded microcosting. SETTING Three English hospital emergency departments (EDs). PARTICIPANTS Patients aged ≥16 with established epilepsy reporting ≥2 ED visits in the prior 12 months and their significant others (SOs). INTERVENTIONS Patients (and their SOs) were randomly allocated (1:1) to SAFE plus treatment-as-usual (TAU) or TAU alone. SAFE is a 4-hour group course. MAIN OUTCOME MEASURES Two criteria evaluated a definitive RCT's feasibility: (1) ≥20% of eligible patients needed to be consented into the pilot trial; (2) routine data on use of ED over the 12 months postrandomisation needed securing for ≥75%. Other measures included eligibility, ease of obtaining routine data, availability of self-report ED data and comparability, SAFE's effect and intervention cost. RESULTS Of ED attendees with a suspected seizure, 424 (10.6%) patients were eligible; 53 (12.5%) patients and 38 SOs consented. Fifty-one patients (and 37 SOs) were randomised. Routine data on ED use at 12 months were secured for 94.1% patients. Self-report ED data were available for 66.7% patients. Patients reported more visits compared with routine data. Most (76.9%) patients randomised to SAFE received it and no related serious adverse events occurred. ED use at 12 months was lower in the SAFE+TAU arm compared with TAU alone, but not significantly (rate ratio=0.62, 95% CI 0.33 to 1.17). A definitive trial would need ~674 patient participants and ~39 recruitment sites. Obtaining routine data was challenging, taking ~8.5 months. CONCLUSIONS In satisfying only one predetermined 'stop/go' criterion, a definitive RCT is not feasible. The low consent rate in the pilot trial raises concerns about a definitive trial's finding's external validity and means it would be expensive to conduct. Research is required into how to optimise recruitment from the target population. TRIAL REGISTRATION NUMBER ISRCTN13871327.

Clinically unnecessary and avoidable emergency health service use for epilepsy: A survey of what English services are doing to reduce it. Seizure 2020; 76:156-160.

Abstract
PURPOSE Epilepsy is associated with costly unplanned health service use. The UK's National Audits of Seizure Management in Hospital found use was often clinically unnecessary, avoidable and typically led to little benefit for epilepsy management. We systematically identified how services have responded to reduce such use. METHODS We invited England's ambulance services, neuroscience and neurology centres and a random sample of Emergency Departments (EDs) to complete a survey. It asked what innovations they (or services they worked with) had made in the past 5 years or were making, the priority afforded to them, user involvement, what comprised usual practice, and barriers to change. RESULTS 72/87 of invited (82.8 %) services responded. EDs ascribed less priority to reducing emergency hospital use for epilepsy and convulsions, than other service types. Overall, 60 % of services reported a change(s) and/or were planning one. Neurology/neuroscience sites (93.8 %) were most likely to report change; EDs (15.4 %) least likely. Eleven types of change were identified; 5 sought to promote proactive epilepsy care and avert the need for emergency care; 3 focused on the care received from emergency services; and 3 focused on follow-up care ED attendees received. Most were for those with established, rather than new epilepsy and targeted known limitations to current care provision. CONCLUSION Reducing emergency hospital use by PWE is a high priority for most health services in England and a number of new services have been developed. However, they have not been consistently implemented and innovation is lacking in some areas of care.

Abstract
BACKGROUND Repeat attendances to emergency departments for seizures, impacts on the individual and burdens health care systems. We conducted a review to identify implementable measures which improve the management of people with epilepsy reducing healthcare costs and their supportive evidence. METHODS A scoping review design using suitable search strategy as outlined by PRISMA-ScR was used to examine seven databases: MEDLINE, EMBASE, CINAHL, AMED, PsychINFO, HMIC and BNI. A manual search of the COCHRANE database and citation searching was also conducted. A thematic analysis was conducted to explore the context and reasons of emergency department attendance for seizures, particularly repeat attendances and the strategies and measures deployed to reduce repeat attendances. RESULTS Twenty-nine reports were included, comprising of a systematic review, a randomised control study, a multi-method study, quantitative studies (n = 17), qualitative studies (n = 6), an audit, a survey and a quality improvement project. Thematic analysis identified four broad areas for reducing repeat attendances. These were developing care pathways, conducting care and treatment reviews, providing educational interventions and role of ambulance staff. CONCLUSION The findings indicate varied reasons for attendance at ED following seizure, including mental health and knowledge of seizure management and lack of education. Implementations of care pathways in ED have been found to reduce admission related costs.

Abstract
BACKGROUND The Irish ambulance services have traditionally transported all patients following an emergency (112/999) call, regardless of acuity, to an emergency department (ED). A proposal to introduce Treat and Referral, an established care pathway in some jurisdictions, is under active consideration in Ireland. This will present a significant change. Stakeholder engagement is recognised as an essential component of management of such change. This study has conducted a multicentre, cross-sectional survey exploring opinions on the introduction of Treat and Referral among key Irish stakeholders; consultants in emergency medicine, paramedics and advanced paramedics. METHODS Public-sector consultants in emergency medicine (EM), registered paramedics and advanced paramedics, in Ireland at the time of the study, were invited to complete an on-line survey. RESULTS A significant finding was that 90% of both cohorts (EM consultants and registered paramedic practitioners) support written after-care instructions being given to referred patients, that > 83% agree that Treat and Referral will reduce unnecessary ambulance journeys and that 70% are in favour of their own family member being offered Treat and Referral. Consensus was reached between respondents that Treat and Referral would improve care and increase clinical judgement of practitioners. Differences were identified in relation to the increased availability of ambulances locally, that only adults should be included, and that research was required to extend Treat and Referral beyond the index conditions. There was no consensus on whether general practitioners (GPs) should be directly informed. CONCLUSIONS This study identified that the Irish healthcare practitioners surveyed are supportive of the introduction of Treat and Referral into Ireland. It also affords healthcare policymakers the opportunity to address the concerns raised, in particular the clinical level which will be targeted for inclusion in this extended scope of practice.

Abstract
INTRODUCTION Emergency department (ED) visits for epilepsy are common, costly, often clinically unnecessary and typically lead to little benefit for epilepsy management. An 'Alternative Care Pathway' (ACP) for epilepsy, which diverts people with epilepsy (PWE) away from ED when '999' is called and leads to care elsewhere, might generate savings and facilitate improved ambulatory care. It is unknown though what features it should incorporate to make it acceptable to persons from this particularly vulnerable target population. It also needs to be National Health Service (NHS) feasible. This project seeks to identify the optimal ACP configuration. METHODS AND ANALYSIS Mixed-methods project comprising three-linked stages. In Stage 1, NHS bodies will be surveyed on ACPs they are considering and semi-structured interviews with PWE and their carers will explore attributes of care important to them and their concerns and expectations regarding ACPs. In Stage 2, Discrete Choice Experiments (DCE) will be completed with PWE and carers to identify the relative importance placed on different care attributes under common seizure scenarios and the trade-offs people are willing to make. The uptake of different ACP configurations will be estimated. In Stage 3, two Knowledge Exchange workshops using a nominal group technique will be run. NHS managers, health professionals, commissioners and patient and carer representatives will discuss DCE results and form a consensus on which ACP configuration best meets users' needs and is NHS feasible. ETHICS AND DISSEMINATION Ethical approval: NRES Committee (19/WM/0012) and King's College London ethics Committee (LRS-18/19-10353). Primary output will be identification of optimal ACP configuration which should be prioritised for implementation and evaluation. A pro-active dissemination strategy will make those considering developing or supporting an epilepsy ACP aware of the project and opportunities to take part in it. It will also ensure they are informed of its findings. PROJECT REGISTRATION NUMBER Researchregistry4723.

Abstract
BACKGROUND Generalized tonic-clonic seizures (GTCS), syncope, and psychogenic nonepileptic seizures (PNES) are common emergent neurological conditions that cause transient disturbances of consciousness; however, it is sometimes difficult to distinguish them. OBJECTIVE This study aimed to explore the value of serum uric acid levels in differentiating among GTCS, syncope, and PNES by analyzing serum uric acid levels in patients with GTCS, syncope, and PNES. METHODS A total of 391 patients were retrospectively analyzed. Venous blood was drawn from the patients within 20 min of their arrival to the emergency department; serum uric acid levels were measured using the uricase method. RESULTS Serum uric acid levels and the percentage of patients with elevated uric acid (elevation percentage) were significantly higher in the group with GTCS (n = 179) than in the groups with syncope (n = 156) (p < 0.001) and PNES (n = 56) (p < 0.001). The result remained the same when the serum uric acid level of male or female patients in the group with GTCS were compared separately with that in the other two groups (all p < 0.001). In the group with GTCS, both the serum uric acid level (p < 0.001) and elevation percentage (p < 0.05) were significantly higher in males than in females. The receiver operating characteristics (ROC) analysis in male patients yielded a serum uric acid value of 428.50 μmol/L with a sensitivity of 0.78 and a specificity of 0.99 as the optimal cutoff value to distinguish GTCS from other events. In female patients, a cutoff value of 338.00 μmol/L had a sensitivity of 0.69 and a specificity of 0.91 to distinguish GTCS from other events. For the group with GTCS, the period of time between the onset of seizure and serum uric acid levels dropping to normal were analyzed in 40 patients. The duration was 44.56 ± 11.46 h for males (n = 23) and 40.37 ± 9.78 h for females (n = 17) with no significant difference (p = 0.325). CONCLUSION Serum uric acid levels provided certain clinical value for the differentiation of GTCS, syncope, and PNES; however, this requires verification in prospective studies with larger sample sizes.

Abstract
OBJECTIVES To determine whether there are differences in the profile and in the care of adult patients with epileptic seizures in emergency department according to age ≥75 years, and if this is independently associated with results in the emergency department and 30 days after discharge. MATERIAL AND METHODS ACESUR is a multicentre, prospective, observational cohort multipurpose register that was carried out in 2017. The distribution of the variables corresponding to the clinical presentation and care according to age ≥75 years were compared. Subsequently, logistic regression models were performed with the objective of evaluating the effect of age ≥75 years on the outcome variables. RESULTS A total of 541 (81.5%) cases younger than 75 years were analysed compared to 123 adult patients (18.5%) of ≥75 years or more. In the group of long-lived it was observed significantly greater probability of dependence, co-morbidity, polypharmacy, a previous visit to the hospital emergency department, arrived by ambulance, first seizures and a symptomatic aetiopathogenic classification. In the multivariate analysis, after adjusting for the above variables, it is observed that age >75 years is associated independently with a higher incidence of specific supplementary tests (OR: 2.31; 95% CI: 1.21-4.44), but not pharmacological intervention (OR: 1.63; 95% CI: 0.96-2.80), or hospitalisation or extended stay in emergency departments (OR: 1.56; 95% CI: 0.94-2.59). On adjusting for all previous variables, age >75 years is associated with lower incidence of adverse events at 30 days (OR: 0.43; 95% CI: 0.25-0.77). CONCLUSIONS In the ACESUR Registry, differences in clinical presentation and in the care of patients with seizures in emergency departments were identified when comparing those patients >75 years with those <75 years. Age ≥75 years is not independently associated with a higher incidence of intervention in emergency departments, or with more adverse outcomes at 30 days after discharge.

Abstract
INTRODUCTION Paramedics make important decisions about whether a patient needs transport to hospital, or can be discharged on scene. These decisions require a degree of accuracy, as taking low acuity patients to the emergency department (ED) can support ambulance ramping. In contrast, leaving mid-high acuity patients on scene can lead to incidents and recontact. This study aims to investigate the accuracy of conveyance decisions made by paramedics when looking at real life patient scenarios with known outcomes. It also aims to explore how the paramedic made the decision. METHODS We undertook a prospective mixed method triangulation design. Six individual patient vignettes were created using linked ambulance and ED data. These were then presented in an online survey to paramedics in Yorkshire. Half the vignettes related to mid-high acuity attendances at the ED and the other half were low acuity. Vignettes were validated by a small expert panel. Participants were asked to determine the appropriate conveyance decision and to explain the rationale behind their decisions using a free-text box. RESULTS A total of 143 paramedics undertook the survey and 858 vignettes were completed. There was clear agreement between paramedics for transport decisions (ƙ = 0.63). Overall accuracy was 0.69 (95% CI 0.66-0.73). Paramedics were better at 'ruling in' the ED, with sensitivity of 0.89 (95% CI 0.86-0.92). The specificity of 'ruling out' the ED was 0.51 (95% CI 0.46-0.56). Text comments were focused on patient safety and risk aversion. DISCUSSION Paramedics make accurate conveyance decisions but are more likely to over-convey than under-convey, meaning that while decisions are safe they are not always appropriate. It is important that paramedics feel supported by the service to make safe and confident non-conveyance decisions. Reducing over-conveyance is a potential method of reducing demand in the urgent and emergency care system.

Assessing Treatment Fidelity within an Epilepsy Randomized Controlled Trial: Seizure First Aid Training for People with Epilepsy Who Visit Emergency Departments. Behav Neurol 2019; 2019:5048794.

Abstract
Purpose To measure fidelity with which a group seizure first aid training intervention was delivered within a pilot randomized controlled trial underway in the UK for adults with epilepsy who visit emergency departments (ED) and informal carers. Estimates of its effects, including on ED use, will be produced by the trial. Whilst hardly ever reported for trials of epilepsy interventions—only one publication on this topic exists—this study provides the information on treatment fidelity necessary to allow the trial's estimates to be accurately interpreted. This rare worked example of how fidelity can be assessed could also provide guidance sought by neurology trialists on how to assess fidelity. Methods 53 patients who had visited ED on ≥2 occasions in prior year were recruited for the trial; 26 were randomized to the intervention. 7 intervention courses were delivered for them by one facilitator. Using audio recordings, treatment “adherence” and “competence” were assessed. Adherence was assessed by a checklist of the items comprising the intervention. Using computer software, competence was measured by calculating facilitator speech during the intervention (didacticism). Interrater reliability was evaluated by two independent raters assessing each course using the measures and their ratings being compared. Results The fidelity measures were found to be reliable. For the adherence instrument, raters agreed 96% of the time, PABAK-OS kappa 0.91. For didacticism, raters' scores had an intraclass coefficient of 0.96. In terms of treatment fidelity, not only were courses found to have been delivered with excellent adherence (88% of its items were fully delivered) but also as intended they were highly interactive, with the facilitator speaking for, on average, 55% of course time. Conclusions The fidelity measures used were reliable and showed that the intervention was delivered as attended. Therefore, any estimates of intervention effect will not be influenced by poor implementation fidelity.

Abstract
OBJECTIVES To establish the appropriateness of a previously developed seizure care pathway by exploring to what extent patients valued the intervention and perceived it as being helpful or not. DESIGN Qualitative descriptive study, using semistructured, in-depth interviews and thematic template analysis, theoretically informed by critical realism. SETTING In North West England, a seizure care pathway has been developed in collaboration with a specialist neurology hospital to support clinical management of seizure patients on initial presentation to the emergency department (ED), as well as access to follow-up services on discharge, with the aim of improving patient experience. Three National Health Service (NHS) EDs and a specialist neurology hospital provided the setting for participant recruitment to this study. PARTICIPANTS 181 patients fulfilled the inclusion criterion with 27 participants taking part following their experience of an ED attendance and outpatient follow-up appointment after a seizure. RESULTS Five main themes emerged from the data: decision to seek care, responsiveness of services, waiting and efficiency, information and support, and care continuity. Two integrative themes spanned the whole study: lived experience and communication. This paper reports on two of the main themes: care continuity, and waiting and efficiency. The average time between ED presentation and interview completion was 100 days. CONCLUSIONS Implementation of a care pathway is a complex intervention, requiring long-term follow-up to assess its integration into practice and effectiveness in service improvement. The seizure care pathway has the potential to enhance the care of seizure patients in the ED and at follow-up by improving continuity and management of care. The study demonstrates good aspects of the seizure care pathway as observed by patients and also recognises shortcomings within current service provision and questions what the NHS should and should not be delivering. Our study suggests various ways to enhance the pathway at service level to potentially drive improved patient experience.

Abstract
Background
In England in 2015/16, ambulance services responded to nearly 11 million calls. Ambulance Quality Indicators show that half of the patients receiving a response by telephone or face to face were not conveyed to an emergency department. A total of 11% of patients received telephone advice only. A total of 38% of patients were sent an ambulance but were not conveyed to an emergency department. For the 10 large ambulance services in England, rates of calls ending in telephone advice varied between 5% and 17%. Rates of patients who were sent an ambulance but not conveyed to an emergency department varied between 23% and 51%. Overall non-conveyance rates varied between 40% and 68%.
Objective
To explain variation in non-conveyance rates between ambulance services.
Design
A sequential mixed methods study with five work packages.
Setting
Ten of the 11 ambulance services serving > 99% of the population of England.
Methods
(1) A qualitative interview study of managers and paramedics from each ambulance service, as well as ambulance commissioners (totalling 49 interviews undertaken in 2015). (2) An analysis of 1 month of routine data from each ambulance service (November 2014). (3) A qualitative study in three ambulance services with different published rates of calls ending in telephone advice (120 hours of observation and 20 interviews undertaken in 2016). (4) An analysis of routine data from one ambulance service linked to emergency department attendance, hospital admission and mortality data (6 months of 2013). (5) A substudy of non-conveyance for people calling 999 with breathing problems.
Results
Interviewees in the qualitative study identified factors that they perceived to affect non-conveyance rates. Where possible, these perceptions were tested using routine data. Some variation in non-conveyance rates between ambulance services was likely to be due to differences in the way rates were calculated by individual services, particularly in relation to telephone advice. Rates for the number of patients sent an ambulance but not conveyed to an emergency department were associated with patient-level factors: age, sex, deprivation, time of call, reason for call, urgency level and skill level of attending crew. However, variation between ambulance services remained after adjustment for patient-level factors. Variation was explained by ambulance service-level factors after adjustment for patient-level factors: the percentage of calls attended by advanced paramedics [odds ratio 1.05, 95% confidence interval (CI) 1.04 to 1.07], the perception of ambulance service staff and commissioners that advanced paramedics were established and valued within the workforce of an ambulance service (odds ratio 1.84, 95% CI 1.45 to 2.33), and the perception of ambulance service staff and commissioners that senior management was risk averse regarding non-conveyance within an ambulance service (odds ratio 0.78, 95% CI 0.63 to 0.98).
Limitations
Routine data from ambulance services are complex and not consistently collected or analysed by ambulance services, thus limiting the utility of comparative analyses.
Conclusions
Variation in non-conveyance rates between ambulance services in England could be reduced by addressing variation in the types of paramedics attending calls, variation in how advanced paramedics are used and variation in perceptions of the risk associated with non-conveyance within ambulance service management. Linking routine ambulance data with emergency department attendance, hospital admission and mortality data for all ambulance services in the UK would allow comparison of the safety and appropriateness of their different non-conveyance rates.

Abstract
INTRODUCTION Paramedics are increasingly expected to take on wider roles in the management of epilepsy in the community by making nonconveyance decisions after patients have had seizures. Studies have identified barriers to the successful implementation of this clinical role. We sought to determine levels of confidence, training, perceived barriers, and self-identified learning needs and methods to address these needs regarding seizure management. METHODS AND MATERIALS A questionnaire was developed by consensus and administered to 63 paramedic and prehospital clinicians at various mandatory training days occurring at the central headquarters of the regional ambulance service in Northern Ireland. Participants had no foreknowledge of the questionnaire, which was self-completed and returned immediately. RESULTS A 75% return rate was obtained after 63 questionnaires were distributed. Paramedics had a mean of 11.5years of experiences, and 49% had treated 1-10 seizures in the last year. The Joint Royal Colleges Ambulance Liaison Committee guideline on seizure management is the most commonly utilized clinical guideline (100%). All could recall formal training on seizures in their qualification course. They identified a need to develop their knowledge in certain aspects of drug management and seizure subtype identification, including nonepileptic attack disorder (NEAD). Seventy percent of paramedics had a limited understanding of NEAD. Overall, paramedics rated their confidence as higher in drug treatment and the process of managing a seizure but rated their confidence lower in recognizing different seizure types as well as making nonconveyance decisions. The two factors which were cited as instilling high confidence included clinical experience and good use of provided protocols. Other barriers identified included lack of access to intramuscular midazolam, poor information availability in the prehospital setting, and a lack of a feedback mechanism to ensure follow-up. The methods by which learning needs would be addressed included tutorials, e-Learning, and simulation, with 30% preferring a combination of these methods. CONCLUSIONS We identified that the paramedic workforce feels a reasonable to high level of confidence in the management of acute seizures. However, there are areas where they experience less confidence including making nonconveyance decisions and the identification of nontonic-clonic seizure subtypes.

First-aid management of tonic-clonic seizures among healthcare personnel: A survey by the Apulian section of the Italian League Against Epilepsy. Epilepsy Behav 2018; 80:321-325. [PMID: 29402633 DOI: 10.1016/j.yebeh.2017.11.017] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2017] [Revised: 11/15/2017] [Accepted: 11/19/2017] [Indexed: 02/07/2023]
Abstract
INTRODUCTION To evaluate the knowledge of healthcare workers about first-aid measures to be performed during and after a tonic-clonic seizure. METHODS One hundred and fifty-four healthcare workers (86 physicians) working at 8 tertiary hospitals in the Apulia region, Italy, responded to a questionnaire comprising of 28 questions based on available Italian and international recommendations about what to do during a tonic-clonic seizure. RESULTS One hundred and fifty-four healthcare workers completed and returned surveys with a response rate of 96.25%. There were 55 nurses (35.7%), 86 physicians (55.8%), and 13 healthcare workers with different roles (Electroencephalograph technicians, psychologists, social workers). Among physicians, there were 7 cardiologists, 3 surgeons, 12 infectious-disease specialists, 11 internal medicine specialists, 2 psychiatrists, 2 gynecologists, 27 specialists working in the emergency department, and 22 physicians with different specializations. Nearly 90% of the respondents identified head protection as important first aid, while 100% responded to not keep the legs elevated. To avoid tongue bite, both physicians and other healthcare workers would put something in the mouth (54.0%), like a Guedel cannula (71.0%) fingers (29.5%). Grabbing arms and legs, trying to stop the seizure, would be potentially performed by 11.6% of our sample. Physicians would administer a benzodiazepine during the seizure (65.7%) and during the postictal phase (29.2%), even if the patient is known to have epilepsy (23.7%), and in this case, 11.3% of respondents would administer the usual antiepileptic medications. More than half of respondents would call the emergency telephone number, because of necessary hospitalization in case of tonic-clonic seizure, even if it is experienced by a patient known to have epilepsy. CONCLUSION Our survey suggests the need for epilepsy educational programs on first-aid management of seizures among healthcare workers.

Abstract
PURPOSE OF REVIEW Optimal treatment of a possible first seizure depends on the determination if the paroxysmal event was an epileptic seizure and was on an accurate assessment of the recurrence risk. This review summarizes evidence from the last 5 years addressing the following questions: Is it an epileptic seizure? Is it a first seizure? When does a first seizure indicate epilepsy? RECENT FINDINGS The acts of taking and interpreting the history from patients and witnesses continue to be the most important tools in the diagnosis of first seizures. Assessment tools based on factual questions and the observation of patients' conversational behaviour can contribute to the differentiation of patients with epileptic seizures from those who have experienced other types of transient loss of consciousness (TLOC). At present, only about 40% of patients are seen after their very first seizure. Tests have a limited role in the initial diagnosis of a seizure but help to determine the recurrence risk based on the cause. A remote symptomatic cause and detection of epileptiform discharges are associated with a recurrence risk of at least 60% and allow a diagnosis of epilepsy after a first seizure. The risk of recurrence after an acute symptomatic first seizure is well below 60%. SUMMARY Expert history-taking continues to be the most important tool in the diagnosis of a first seizure. Cause is the most important determinant of the recurrence risk. Unfortunately, there is currently no formula enabling a precise calculation of an individualized recurrence risk.

Abstract
OBJECTIVE To determine the clinical characteristics, management and outcomes of patients taken to hospital by emergency ambulance after a suspected seizure. DESIGN Quantitative cross-sectional retrospective study of a consecutive series of patients. SETTING An acute hospital trust in a large city in England. PARTICIPANTS In 2012-2013, the regions' ambulance service managed 605 481 emergency incidents, 74 141/605 481 originated from Sheffield (a large city in the region), 2121/74 141 (2.9%) were suspected seizures and 178/2121 occurred in May 2012. We undertook detailed analysis of the medical records of the 91/178 patients who were transported to the city's acute hospital. After undertaking a retrospective review of the medical records, the best available aetiological explanation for the seizures was determined. RESULTS The best available aetiological explanation for 74.7% (68/91) of the incidents was an epileptic seizure, 11.0% (10/91) were psychogenic non-epileptic seizures and 9.9% (9/91) were cardiogenic events. The epileptic seizures fall into the following four categories: first epileptic seizure (13.2%, 12/91), epileptic seizure with a historical diagnosis of epilepsy (30.8%, 28/91), recurrent epileptic seizures without a historical diagnosis of epilepsy (20.9%, 19/91) and acute symptomatic seizures (9.9%, 9/91). Of those with seizures (excluding cardiogenic events), 2.4% (2/82) of patients were seizing on arrival in the Emergency Department (ED), 19.5% (16/82) were postictal and 69.5% (57/82) were alert. 63.4% (52/82) were discharged at the end of their ED attendance and 36.5% (19/52) of these had no referral or follow-up. CONCLUSIONS Most suspected seizures are epileptic seizures but this is a diagnostically heterogeneous group. Only a small minority of patients require emergency medical care but most are transported to hospital. Few patients receive expert review and many are discharged home without referral to a specialist leaving them at risk of further seizures and the associated morbidity, mortality and health services costs of poorly controlled epilepsy.

Abstract
INTRODUCTION The UK ambulance service often attends to suspected seizures. Most persons attended to will not require the facilities of a hospital emergency department (ED) and so should be managed at scene or by using alternative care pathways. Most though are transported to ED. One factor that helps explain this is paramedics can have low confidence in managing seizures. OBJECTIVES With a view to ultimately developing additional seizure management training for practicing paramedics, we explored their learning needs, delivery preferences and potential drivers and barriers to uptake and effectiveness. DESIGN AND SETTING Semistructured interviews were conducted with a purposive sample of paramedics from the English ambulance service. Interviews were transcribed and thematically analysed. PARTICIPANTS A diverse sample of 19 professionals was recruited from 5 different ambulance NHS trusts and the College of Paramedics. RESULTS Participants said seizure management was neglected within basic and postregistration paramedic training. Most welcomed additional learning opportunities and identified gaps in knowledge. This included how to differentiate between seizure types and patients that do and do not need ED. Practical, interactive e-learning was deemed the most preferable delivery format. To allow paramedics to fully implement any increase in skill resulting from training, organisational and structural changes were said to be needed. This includes not penalising paramedics for likely spending longer on scene. CONCLUSIONS This study provides the first evidence on the learning needs and preferences of paramedics regarding seizures. It can be used to inform the development of a bespoke training programme for paramedics. Future research should develop and then assess the benefit such training has on paramedic confidence and on the quality of care they offer to seizure patients.

Abstract
OBJECTIVES The UK ambulance service is expected to now manage more patients in the community and avoid unnecessary transportations to hospital emergency departments (ED). Most people it attends who have experienced seizures have established epilepsy, have experienced uncomplicated seizures and so do not require the full facilities of an ED. Despite this, most are transported there. To understand why, we explored paramedics' experiences of managing seizures. DESIGN AND SETTING Semistructured interviews were conducted with a purposive sample of paramedics from the English ambulance service. Interviews were transcribed and thematically analysed. PARTICIPANTS A diverse sample of 19 professionals was recruited from 5 different ambulance NHS trusts and the College of Paramedics. RESULTS Participants' confirmed how most seizure patients attended to do not clinically require an ED. They explained, however, that a number of factors influence their care decisions and create a momentum for these patients to still be taken. Of particular importance was the lack of access paramedics have to background medical information on patients. This, and the limited seizure training paramedics receive, meant paramedics often cannot interpret with confidence the normality of a seizure presentation and so transport patients out of precaution. The restricted time paramedics are expected to spend 'on scene' due to the way the ambulance services' performance is measured and that are few alternative care pathways which can be used for seizure patients also made conveyance likely. CONCLUSIONS Paramedics are working within a system that does not currently facilitate non-conveyance of seizure patients. Organisational, structural, professional and educational factors impact care decisions and means transportation to ED remains the default option. Improving paramedics access to medical histories, their seizure management training and developing performance measures for the service that incentivise care that is cost-effective for all of the health service might reduce unnecessary conveyances to ED.

Abstract
Most work addressing clinical workers' professional responsibilities concerns the norms of conduct within established professional-patient relationships, but such responsibilities may extend beyond the clinical context. We explore health workers' professional responsibilities in such "informal" encounters through the example of a doctor witnessing the misdiagnosis and mistreatment of a serious long-term condition in a television documentary, arguing that neither internalist approaches to professional responsibility (such as virtue ethics or care ethics) nor externalist ones (such as the "social contract" model) provide sufficiently clear guidance in such situations. We propose that a mix of both approaches, emphasizing the noncomplacency and practical wisdom of virtue ethics, but grounding the normative authority of virtue in an external source, is able to engage with the health worker's responsibilities in such situations to the individual, the health care system, and the population at large.

Abstract
OBJECTIVE Epileptic seizures, syncope, and psychogenic nonepileptic seizures (PNES) account for over 90% of presentations with transient loss of consciousness (TLOC). The patient's history is crucial for the diagnosis, but the diagnostic value of individual semiologic features is limited. This study explores the diagnostic potential of a comprehensive questionnaire focusing on TLOC-associated symptoms. METHODS A total of 386 patients with proven epilepsy, 308 patients with proven PNES, and 371 patients with proven syncope were approached by post to recruit 100 patients in each diagnostic group. Symptoms were self-reported on an 86-item questionnaire (the Paroxysmal Event Profile [PEP]) using a 5-point Likert scale (always to never). Data were subjected to exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA). Factors were used to differentiate between diagnoses by pairwise and multinomial regression. RESULTS Patients with PNES reported more and more frequent TLOC-associated symptoms than those with epilepsy or syncope (p < 0.001). EFA/CFA identified a 5-factor structure based on 74/86 questionnaire items with loadings ≥0.4. Pairwise logistic regression analysis correctly classified 91% of patients with epilepsy vs those with syncope, 94% of those with PNES vs those with syncope, and 77% of those with epilepsy vs those with PNES. Multinomial logistic regression analysis yielded a similar pattern. CONCLUSIONS Clusters of self-reported TLOC symptoms can be used to direct patients to appropriate investigation and treatment pathways for syncope on the one hand and seizures on the other, although additional information is required for a reliable distinction, especially between epilepsy and PNES.
