Experiences from a cluster-randomized trial (ParaNASPP) exploring triage and diagnostic accuracy in paramedic-suspected stroke: a qualitative interview study.

BACKGROUND AND PURPOSE: Timely prehospital stroke recognition was explored in the Paramedic Norwegian Acute Stroke Prehospital Project (ParaNASPP) by implementation of stroke education for paramedics and use of the National Institutes of Health Stroke Scale (NIHSS) through a mobile application. The study tested triage and facilitated communication between paramedics and stroke physicians. To complement the quantitative results of the clinical trial, a qualitative approach was used to identify factors that influence triage decisions and diagnostic accuracy in prehospital stroke recognition experienced by paramedics and stroke physicians. METHOD: Semi-structured qualitative individual interviews were performed following an interview guide. Informants were recruited from the enrolled paramedics and stroke physicians who participated in the ParaNASPP trial from Oslo University Hospital. Interviews were audio recorded, transcribed verbatim and approached inductively using the principles of thematic analysis. RESULTS: Fourteen interviews were conducted, with seven paramedics and seven stroke physicians. Across both groups two overarching themes were identified related to triage decisions and diagnostic accuracy in prehospital stroke recognition: prehospital NIHSS reliably improves clinical assessment and communication quality; overtriage is widely accepted whilst undertriage is not. CONCLUSION: Paramedics and stroke physicians described how prehospital NIHSS improved communication quality and reliably improved prehospital clinical assessment. The qualitative results support a rationale of an application algorithm to decide which NIHSS items should prompt immediate prenotification rather than a complete NIHSS as default.

Prepulse inhibition and the call alert in emergency medical services.

In emergency medical services, paramedics are informed of an emergency call by a high-intensity acoustic alarm called the "call alert." Sudden, loud sounds like the call alert may cause a startle response and be experienced as aversive. Studies have identified an association between the call alert and adverse health effects in first responders; conceivably, these adverse health effects might be reduced by modifying the call alert to blunt its startling and aversive properties. Here, we assessed whether the call alert causes a startle response and whether its startling and aversive properties are reduced when the call alert is preceded by a weak acoustic "prepulse," a process referred to as "prepulse inhibition" (PPI). Paramedics (n = 50; 34M:13F:3 not reported; ages 20-68) were exposed to four call alerts (two with and two without a prepulse) in counterbalanced order. Responses were measured using electromyography (measuring blink amplitude), visual analog scales (quantifying perceived call alert intensity and aversiveness), and an electrocardiogram (assessing heart rate). Paramedics responded to the call alert with a startle reflex blink and an increased heart rate. Acoustic prepulses significantly reduced the amplitude of the call alert-induced startle blink, the perceived sound intensity, and the perceived "dislike" of the call alert. These findings confirm that the call alert is associated with an acoustic startle response in paramedics; adding a prepulse to the call alert can reduce its startling and aversive properties. Conceivably, such reductions might also diminish adverse health effects associated with the call alert in first responders.

Sepsis incidence, suspicion, prediction and mortality in emergency medical services: a cohort study related to the current international sepsis guideline.

PURPOSE: Sepsis suspicion by Emergency Medical Services (EMS) is associated with improved patient outcomes. This study assessed sepsis incidence and recognition by EMS and analyzed which of the screening tools recommended by the Surviving Sepsis Campaign best facilitates sepsis prediction. METHODS: Retrospective cohort study of claims data from health insurances (n = 221,429 EMS cases), and paramedics' and emergency physicians' EMS documentation (n = 110,419); analyzed outcomes were: sepsis incidence and case fatality compared to stroke and myocardial infarction, the extent of documentation for screening-relevant variables and sepsis suspicion, tools' intersections for screening positive in identical EMS cases and their predictive ability for an inpatient sepsis diagnosis. RESULTS: Incidence of sepsis (1.6%) was similar to myocardial infarction (2.6%) and stroke (2.7%); however, 30-day case fatality rate was almost threefold higher (31.7% vs. 13.4%; 11.8%). Complete vital sign documentation was achieved in 8.2% of all cases. Paramedics never, emergency physicians rarely (0.1%) documented a sepsis suspicion, respectively septic shock. NEWS2 had the highest sensitivity (73.1%; Specificity:81.6%) compared to qSOFA (23.1%; Sp:96.6%), SIRS (28.2%; Sp:94.3%) and MEWS (48.7%; Sp:88.1%). Depending on the tool, 3.7% to 19.4% of all cases screened positive; only 0.8% in all tools simultaneously. CONCLUSION: Incidence and mortality underline the need for better sepsis awareness, documentation of vital signs and use of screening tools. Guidelines may omit MEWS and SIRS as recommendations for prehospital providers since they were inferior in all accuracy measures. Though no tool performed ideally, NEWS2 qualifies as the best tool to predict the highest proportion of septic patients and to rule out cases that are likely non-septic.

'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.

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.

Out-of-hospital paramedic interactions with people living with dementia: a scoping review.

BACKGROUND: Dementia encompasses neurodegenerative disorders that account for a global estimated healthcare expenditure of 1.3 trillion US dollars. In Australia, one in 12 people aged ≥65 has a diagnosis of dementia and it is the second leading cause of death. Paramedics play a crucial role in person-centred dementia care, particularly in the community. While consensus has been established on paramedicine's integration into interdisciplinary care teams, there remains a lack of clarity regarding the paramedic role in dementia care. OBJECTIVE: This study aimed to examine and report paramedic interactions with people living with dementia in the out-of-hospital setting. DESIGN AND SETTING: This was a scoping review study of paramedics and people living with dementia within the out-of-hospital setting. METHODS: This study was guided by the Joanna Briggs Institute (JBI) scoping review framework. Databases were searched without date limits, up to 4 April 2023. These encompassed OVID Medline, CINAHL, Scopus, APA PsycInfo and OVID Embase. Articles were included if they were primary, peer-reviewed studies in English and reporting on paramedic-specific interactions with people living with dementia in the out-of-hospital setting. Data extraction was performed based on study setting, design, population and key findings. RESULTS: Twenty-nine articles were included in the thematic analysis. Four themes emerged: need for training, patterns of attendances, patterns of documentation and the integrative potential of paramedicine. Paramedics reported feeling ill-equipped and unprepared in caring for patients living with dementia due to challenges in assessment and management of caregiver tensions. They were often called as a last resort due to poor service integration and a lack of alternative care pathways. Despite high conveyance rates, there was low incidence of paramedic interventions initiated. Underdocumentation of dementia and pain was found. CONCLUSION: Emergency ambulance conveyance of people living with dementia is a surface reaction compounded by a lack of direction for paramedics in the provision of out-of-hospital care. There is a pressing need for establishment of research and educational priorities to improve paramedic training in dementia-specific skillsets.

Development of a palliative paramedicine framework to standardise best practice: A Delphi study.

BACKGROUND: Growing global demand for palliative care services has prompted generalist clinicians to provide adjunct support to specialist teams. Paramedics are uniquely placed to respond to these patients in the community. However, embedding palliative care principles into their core business will require multifactorial interventions at structural, healthcare service and individual clinician and consumer levels. AIM: To develop a palliative paramedicine framework suitable for national implementation, to standardise best practice in Australia. DESIGN: Delphi study utilising questionnaire completion; each round informed the need for, and content of, the next round. Free text comments were also sought in Round 1. Two rounds of Delphi were undertaken. SETTING/PARTICIPANTS: Sixty-eight participants took part in Round 1, representing six countries, and 66 in Round 2. Participants included paramedics, palliative care doctors and nurses, general practitioners, researchers and carers with lived experience and expertise in palliative paramedicine. RESULTS: Seventeen of the original 24 components gained consensus; 6 components were modified; and 9 new components arose from Round 1. All modified and new components gained consensus in Round 2. Only one original component did not gain consensus across both rounds and was excluded from the final 32-component framework. CONCLUSION: This study has developed a comprehensive national framework addressing the macro-, meso- and micro-level interventions required to standardise palliative paramedicine across Australia. Future research ought to engage a multidisciplinary team to create an implementation strategy, addressing any perceived barriers, facilitators and challenges for applying the framework into policy and practice.

Prevalence of anxiety, depression, and post-traumatic stress disorder among paramedic students: a systematic review and meta-analysis.

PURPOSE: There are elevated mental health concerns in paramedic students, but estimates vary between studies and countries, and no review has established the overall prevalence. This systematic review addressed this by estimating the global prevalence of common mental health disorders, namely anxiety, depression, and post-traumatic stress disorder (PTSD), in paramedic students internationally. METHODS: A systematic search of six databases, including MEDLINE, EMBASE, PsycINFO, CINAHL, Scopus, and medRxiv, was conducted to identify studies relating to mental health among paramedicine students. The search encompassed studies from inception until February 2023. To be considered for inclusion in the review, the studies had to report prevalence data on at least one symptom of anxiety, depression, or PTSD in paramedicine students, using quantitative validated scales. The quality of the studies was assessed using Joanna Briggs Institute (JBI) Checklist, which is a specific methodological tool for assessing prevalence studies. Subgroup analyses were not conducted due to insufficient data. RESULTS: 1638 articles were identified from the searches, and 193 full texts were screened, resulting in 13 papers for the systematic review and meta-analysis. The total number of participants was 1064 from 10 countries. The pooled prevalence of moderate PTSD was 17.9% (95% CI 14.8-21.6%), anxiety was 56.4% (95% CI 35,9-75%), and depression was at 34.7% (95% CI 23.4-48.1%). CONCLUSION: This systematic review and meta-analysis has found that paramedicine students globally exhibit a high prevalence of moderate PTSD, anxiety, and depression. The prevalence of these mental health conditions surpasses those among paramedic providers and the general population, as indicated by previous reviews. Further research is therefore warranted to determine appropriate support and interventions for this group.

Challenges of pre-hospital emergency care at Addis Ababa Fire and Disaster Risk Management Commission, Addis Ababa, Ethiopia: a qualitative study.

BACKGROUND: A challenge to pre-hospital emergency care is any barrier or obstacle that impedes quality pre-hospital care or impacts community pre-hospital utilization. The Addis Ababa Fire and Disaster Risk Management Commission (AAFDRMC) provides pre-hospital emergency services in Addis Ababa, Ethiopia. These services operate under a government-funded organization that delivers free emergency services, including out-of-hospital medical care and transportation to the most appropriate health facility. This study aimed to assess the challenges of pre-hospital emergency care at the Addis Ababa Fire and Disaster Risk Management Commission in Addis Ababa, Ethiopia. METHODS: A qualitative descriptive study was conducted from November 20 to December 4, 2022. Data were collected through in-depth, semi-structured interviews with 21 experienced individuals in the field of pre-hospital emergency care, who were selected using purposeful sampling. A thematic analysis method was used to analyze the data. RESULTS: This study includes twenty-one participants working at the Addis Ababa Fire and Disaster Risk Management Commission. Three major themes emerged. The themes that arose were the participants' perspectives on the challenges of pre-hospital emergency care in Addis Ababa, Ethiopia. CONCLUSION AND RECOMMENDATION: The Fire and Disaster Risk Management Commission faces numerous challenges in providing quality pre-hospital emergency care in Addis Ababa. Respondents stated that infrastructure, communication, and resources were the main causes of pre-hospital emergency care challenges. There has to be more focus on emergency management in light of infrastructure reform, planning, staff training, and education, recruiting additional professional power, improving communication, and making pre-hospital emergency care an independent organization in the city.

Paramedics' experiences of barriers to, and enablers of, responding to suspected or confirmed COVID-19 cases: a qualitative study.

BACKGROUND: Paramedics' work, even pre-pandemic, can be confronting and dangerous. As pandemics add extra stressors, the study explored paramedics' lived experience of the barriers to, and enablers of, responding to suspected or confirmed Coronavirus Disease 2019 (COVID-19) cases. METHODS: This exploratory-descriptive qualitative study used semi-structured interviews to investigate Queensland metropolitan paramedics' experiences of responding to cases during the COVID-19 pandemic. Interview transcripts were analysed using thematic analysis. Registered Paramedics were recruited by criterion sampling of staff who experienced the COVID-19 pandemic as active officers. RESULTS: Nine registered paramedics participated. Five themes emerged: communication, fear and risk, work-related protective factors, leadership, and change. Unique barriers included impacts on effective communication due to the mobile nature of paramedicine, inconsistent policies/procedures between different healthcare facilities, dispatch of incorrect information to paramedics, assisting people to navigate the changing healthcare system, and wearing personal protective equipment in hot, humid environments. A lower perceived risk from COVID-19, and increased empathy after recovering from COVID-19 were unique enablers. CONCLUSIONS: This study uncovered barriers and enablers to attending suspected or confirmed COVID-19 cases unique to paramedicine, often stemming from the mobile nature of prehospital care, and identifies the need for further research in paramedicine post-pandemic to better understand how paramedics can be supported during public health emergencies to ensure uninterrupted ambulance service delivery.

"This is how I'm going to do it, but this is not how you're going to do it": the expectation gap between student paramedics and mentors in East and Central Scotland.

BACKGROUND: The role of paramedics has expanded significantly over the past two decades, requiring advanced skills and education to meet the demands of diverse healthcare settings. In 2021, the academic requirements for paramedics were raised to a bachelor's degree to align with other registered professions. The limited evidence on effective paramedic practice education necessitates a novel or new examination of unique learning methods, emphasising the need to establish effective learning relationships between mentors and learners to enhance professional respect and support achieving learning outcomes. This study aimed to investigate expectations between student paramedics and their mentors, focusing on the learning dynamics within paramedic education. METHODS: This qualitative study used purposive sampling to recruit participants from two distinct cohorts: student paramedics from the University of Stirling and Practice Educator Mentors from the Scottish Ambulance Service. Focus groups were conducted to illuminate comprehensive insights into participants' expectations regarding practice education and their respective roles in the learning process. Codebook thematic analysis was used to assess the alignment of these expectations. RESULTS: Findings illustrate important challenges within practice placement across learning paradigms and highlight the attitudes surrounding the integration of higher education and expectations of practice placements. These challenges encompass systemic barriers, including the support provided to mentors as they assume increased responsibilities and barriers that deter qualified staff from initially undertaking this role. CONCLUSION: The study aimed to assess expectations between practice educators and students within the paramedic profession in Scotland. The methodology effectively identified key themes from comprehensive data, marking the first primary research in this field. There are disparities in learning styles, expectation measurement, and attitudes toward higher education during practice placements, which could significantly impact the teaching and assessment processes. The findings suggest increased support for practice educators, educational programs addressing challenges of mentorship, and stronger links between higher education institutes and the Scottish Ambulance Service. Further research is needed to understand the extent of the expectation gap, how expectations evolve, and to develop strategies to address disparities.

Development and evaluation of a point-of-care ultrasound curriculum for paramedics in Germany - a prospective observational study and comparison.

BACKGROUND: Point-of-care ultrasound (POCUS) is steadily growing in use in prehospital emergency medicine. While currently used primarily by emergency physicians, POCUS could also be employed by paramedics to support diagnosis and decision-making. Yet to date, no paramedicine-targeted POCUS curricula exist in Germany. Furthermore, given time and resource constraints in paramedic training, it is unclear whether paramedics could feasibly learn POCUS for prehospital deployment. Hence, this study outlines the development and implementation of a comprehensive POCUS curriculum for paramedics. Through this curriculum, we investigate whether paramedics can attain proficiency in POCUS comparable to other user groups. METHODS: In this prospective observational study, we first developed a blended learning-based POCUS curriculum specifically for paramedics, focusing on basic principles, the RUSH-Protocol and ultrasound guided procedures. Participants underwent digital tests to measure their theoretical competence before (T1) and after the digital preparation phase (T2), as well as at the end of the on-site phase (T3). At time point T3, we additionally measured practical competence using healthy subjects and simulators. We compared the theoretical competence and the practical competence on a simulator with those of physicians and medical students who had also completed ultrasound training. Furthermore, we carried out self-assessment evaluations, as well as evaluations of motivation and curriculum satisfaction. RESULTS: The paramedic study group comprised n = 72 participants. In the theoretical test, the group showed significant improvement between T1 and T2 (p < 0.001) and between T2 and T3 (p < 0.001). In the practical test on healthy subjects at T3, the group achieved high results (87.0% ± 5.6). In the practical test on a simulator at T3, paramedics (83.8% ± 6.6) achieved a lower result than physicians (p < 0.001), but a comparable result to medical students (p = 0.18). The results of the study group's theoretical tests (82.9% ± 9.2) at time point T3 were comparable to that of physicians (p = 0.18) and better than that of medical students (p < 0.01). The motivation and attitude of paramedics towards the prehospital use of POCUS as well as their self-assessment significantly improved from T1 to T3 (p < 0.001). The overall assessment of the curriculum was positive (92.1 ± 8.5). CONCLUSION: With our tailored curriculum, German paramedics were able to develop skills in POCUS comparable to those of other POCUS learners. Integration of POCUS into paramedics' training curricula offers opportunities and should be further studied.

Exploring paramedics' lived experiences in confrontation with patients' death during missions: a phenomenological study.

BACKGROUND: Emergency personnel are the first line of emergency response systems to respond to emergencies; in essence, they are usually exposed to a wide range of physical and psychological problems. Accordingly, the current study aimed to clarify the lived experiences of paramedics when exposed to Patients' Deaths during their missions in 2023. METHODS: This study was carried out using a qualitative approach and interpretative phenomenology from January 9, 2022, to September 21, 2023. The research was performed in Fars, Alborz, and Isfahan provinces in Iran. Data were gathered using semi-structured interviews with 17 male emergency personnel (both from the emergency medical service and Red Crescent). The obtained data were analyzed utilizing Smith's approach to clarify the lived experiences of emergency responders when facing deaths in various incidents in Iran. RESULTS: Seventeen emergency personnel with the age range of 24-60 (average = 39) years and with a history of confronting patients' deaths during their services were interviewed. Their lived experiences of being exposed to patients' deaths during the emergency response in Iran were classified into three main themes: psychological and emotional status, personality, disposition, and behavior status, and mental and physical status. Sub-themes such as psychological and emotional problems, mental and physical problems, and sub-subthemes such as anxiety, stress, decreased appetite, irritability, insomnia, forgetfulness, and fatigue were also noted within the main themes. CONCLUSION: While emergency personnel work diligently to save the lives of patients, the current study demonstrated that they were susceptible to multiple psychological, emotional, and physical problems, which potentially affect their lives outside of the workplace and make them more vulnerable to related physiological and psychological diseases. It is recommended that policymakers and clinical educators make ways to prevent these problems and provide emergency personnel with physical, psychological, and emotional support.

Negotiating grey areas: an interview-based analysis of paramedic uncertainty and decision-making in cardiac arrest events.

BACKGROUND: Paramedics are responsible for critical resuscitation decisions when attending Out of Hospital Cardiac Arrests (OHCA). Existing research indicates that a range of clinical and non-clinical factors moderate their decision-making. Within the United Kingdom (UK), there is little evidence on how and why paramedics make their decisions at actual OHCA events. METHODS: We explored the experiences of UK paramedics using individually recalled OHCA events as catalysts for discussion. Pen portraits developed from semi-structured interviews with 31 paramedics across two UK ambulance services were thematically analysed, enabling cross-participant comparisons whilst retaining depth and context. RESULTS: We identified four themes: uncertainties encountered in resuscitation guidelines, influences on decision-making, holistic perspectives, and indirect moderators. We found that paramedics experienced uncertainty at all stages of the resuscitation process. Uncertainties arose from indeterminate, ambiguous or complex information and were described as having both clinical and ethical dimensions. Whilst guidelines drove paramedics' decisions, non-clinical personal, practical and relational factors moderated their assessments of survivability and decision-making, with attitudes to interactions between patient age, frailty and quality of life playing a substantial role. Coping strategies such as uncertainty reduction, assumption-based reasoning and weighing pros and cons were evident from interviews. CONCLUSIONS: The complexity of interactions between clinical and non-clinical factors points to an element of variability in paramedics' responses to uncertainty. Exploring UK paramedics' uncertainties and decision-making during specific OHCA events can help acknowledge and address uncertainties in resuscitation guidelines and paramedic training, providing paramedics with the tools to manage uncertainty in a consistent and transparent way.

Paramedic attitudes and experiences working as a community paramedic: a qualitative survey.

BACKGROUND: Community paramedicine (CP) is an extension of the traditional paramedic role, where paramedics provide non-acute care to patients in non-emergent conditions. Due to its success in reducing burden on hospital systems and improving patient outcomes, this type of paramedic role is being increasingly implemented within communities and health systems across Ontario. Previous literature has focused on the patient experience with CP programs, but there is lack of research on the paramedic perspective in this role. This paper aims to understand the perspectives and experiences, both positive and negative, of paramedics working in a CP program towards the community paramedic role. METHODS: An online survey was distributed through multiple communication channels (e.g. professional organizations, paramedic services, social media) and convenience sampling was used. Five open-ended questions asked paramedics about their perceptions and experiences with the CP role; the survey also collected demographic data. While the full survey was open to all paramedics, only those who had experience in a CP role were included in the current study. The data was qualitatively analyzed using a comparative thematic analysis. RESULTS: Data was collected from 79 respondents who had worked in a CP program. Three overarching themes, with multiple sub-themes, were identified. The first theme was that CP programs fill important gaps in the healthcare system. The second was that they provide paramedics with an opportunity for lateral career movement in a role where they can have deeper patient connections. The third was that CP has created a paradigm shift within paramedicine, extending the traditional scope of the practice. While paramedics largely reported positive experiences, there were some negative perceptions regarding the slower pace of work and the "soft skills" required in the role that vary from the traditional paramedic identity. CONCLUSIONS: CP programs utilize paramedic skills to fill a gap in the healthcare system, can improve paramedic mental health, and also provide a new pathway for paramedic careers. As a new role, there are some challenges that CP program planners should take into consideration, such as additional training needs and the varying perceptions of CP.

The Influence of Contextual and Theoretical Expertise on Generic and Occupation-Specific Lifting Strategy.

OBJECTIVE: To determine whether (i) low back loads and/or (ii) kinematic coordination patterns differed across theoretical expert, contextual expert and novice groups when completing both generic and occupation-specific lifts. BACKGROUND: Experience has been proposed as a factor that could reduce biomechanical exposures in lifting, but the literature reports mixed effects. The inconsistent relationship between experience and exposures may be partially attributable to the broad classification of experience and experimental lifting protocols not replicating the environment where experience was gained. METHODS: Purposive sampling was used to recruit 72 participants including theoretical experts (formal training on lifting mechanics), contextual experts (paramedics), and novices. Participants performed 10 barbell and crate (generic) lifts, as well as backboard and stretcher (occupation-specific) lifts while whole-body kinematics and ground reaction forces were collected. Peak low back compression and anteroposterior shear loads normalized to body mass, as well as kinematic coordination patterns, were calculated as dependent variables. RESULTS: No significant differences in low back loads were observed across expertise groups. However, significant differences were seen in kinematic coordination patterns across expertise groups in occupation-specific lifts, but not in generic lifts. CONCLUSION: Increasing expertise is unlikely to minimize low back loads in lifting. However, contextual expertise did influence lifting kinematics, but only when performing occupationally specific lifts. APPLICATION: Contextual expertise may help lifters adopt lifting kinematics that enhance the tolerance of their musculoskeletal system to withstand applied loads, but does not seem to reduce the applied low back loads relative to noncontextual expert groups.

[PRACTICE AND TRAINING RELATED TO USING ADRENALINE AUTOINJECTORS FOR PARAMEDICS: FACTS AND ISSUES].

BACKGROUND: Although paramedics can use adrenaline autoinjectors (AAIs) during their duties, the actual conditions of their use and the challenges faced remain unclear. We investigated the actual situation and issues pertaining to creating an environment in which paramedics can operate AAIs more effectively. METHODS: A web-based survey was conducted among paramedics who participated in a web-based training session related to their latest knowledge on food allergies and emergency responses in 2022. The survey items included practice and training environments, practices of AAI administration, and regarding AAI administration. RESULTS: Seventy paramedics responded to the survey. Twenty-eight respondents (40%) had experienced cases in which they wished they had an AAI in their work to date, but only one had actually administered one. Thirty-four (49%) indicated that it would be good to have an AAI in the ambulance at all times; 48 (69%) were not concerned about the use of AAI, and the level of concern about its use was significantly related to length of service. The study also revealed that paramedics do not have an adequate training environment regarding AAI. CONCLUSION: Few paramedics have experience in administering AAI, although they are aware of the need for it. For more effective use of AAI, it is necessary to establish a training environment to familiarize paramedics with anaphylaxis and an environment that enables them to use AAI promptly in the field.

Suicide among emergency service workers: a retrospective mortality study of national coronial data, 2001-2017.

BACKGROUND: Emergency service workers (ESW) are known to be at increased risk of mental disorders but population-level and longitudinal data regarding their risk of suicide are lacking. METHOD: Suicide data for 2001-2017 were extracted from the Australian National Coronial Information Service (NCIS) for two occupational groups: ESW (ambulance personnel, fire-fighters and emergency workers, police officers) and individuals employed in all other occupations. Age-standardised suicide rates were calculated and risk of suicide compared using negative binomial regression modelling. RESULTS: 13 800 suicide cases were identified among employed adults (20-69 years) over the study period. The age-standardised suicide rate across all ESW was 14.3 per 100 000 (95% CI 11.0-17.7) compared to 9.8 per 100 000 (95% CI 9.6-9.9) for other occupations. Significant occupational differences in the method of suicide were identified (p < 0.001). There was no evidence for increased risk of suicide among ESW compared to other occupations once age, gender and year of death were accounted for (RR = 0.99, 95% CI 0.84-1.17; p = 0.95). In contrast, there was a trend for ambulance personnel to be at elevated risk of suicide (RR = 1.41, 95% CI 1.00-2.00, p = 0.053). CONCLUSION: Whilst age-standardised suicide rates among ESW are higher than other occupations, emergency service work was not independently associated with an increased risk of suicide, with the exception of an observed trend in ambulance personnel. Despite an increased focus on ESW mental health and wellbeing over the last two decades, there was no evidence that rates of suicide among ESW are changing over time.

'It breaks a narrative of paramedics, that we're lifesavers': A qualitative study of health professionals', bereaved family members' and carers' perceptions and experiences of palliative paramedicine.

BACKGROUND: Paramedic practice is diversifying to accommodate evolving global health trends, including community paramedicine models and growing expertise in palliative and end-of-life care. However, despite palliative care specific clinical practice guidelines and existing training, paramedics still lack the skills, confidence and clinical support to provide this type of care. AIM: To elicit paramedics', palliative care doctors and nurses', general practitioners', residential aged care nurses' and bereaved families and carers' experiences, perspectives, and attitudes on the role, barriers and enablers of paramedics delivering palliative and end-of-life care in community-based settings. DESIGN: A qualitative study employing reflexive thematic analysis of data collected from semi-structured online interviews was utilised. SETTING/PARTICIPANTS: A purposive sample of 50 stakeholders from all Australian jurisdictions participated. RESULTS: Five themes were identified: positioning the paramedic (a dichotomy between the life saver and community responder); creating an identity (the trusted clinician in a crisis), fear and threat (feeling afraid of caring for the dying), permission to care (seeking consent to take a palliative approach) and the harsh reality (navigating the role in a limiting and siloed environment). CONCLUSION: Paramedics were perceived to have a revered public identity, shaped by their ability to fix a crisis. However, paramedics and other health professionals also expressed fear and vulnerability when taking a palliative approach to care. Paramedics may require consent to move beyond a culture of curative care, yet all participant groups recognised their important adjunct role to support community-based palliative care.

A systematic review of ambulance service-based randomised controlled trials in stroke.

BACKGROUND: Treatment for stroke is time-dependent, and ambulance services play a vital role in the early recognition, assessment and transportation of stroke patients. Innovations which begin in ambulance services to expedite delivery of treatments for stroke are developing. However, research delivery in ambulance services is novel, developing and not fully understood. AIMS: To synthesise literature encompassing ambulance service-based randomised controlled interventions for acute stroke with consideration to the characteristics of the type of intervention, consent modality, time intervals and issues unique to research delivery in ambulance services. Online searches of MEDLINE, EMBASE, Web of Science, CENTRAL and WHO IRCTP databases and hand searches identified 15 eligible studies from 538. Articles were heterogeneous in nature and meta-analysis was partially available as 13 studies reported key time intervals, but terminology varied. Randomised interventions were evident across all points of contact with ambulance services: identification of stroke during the call for help, higher dispatch priority assigned to stroke, on-scene assessment and clinical interventions, direct referral to comprehensive stroke centres and definitive care delivery at scene. Consent methods ranged between informed patient, waiver and proxy modalities with country-specific variation. Challenges unique to the prehospital setting comprise the geographical distribution of ambulance resources, low recruitment rates, prolonged recruitment phases, management of investigational medicinal product and incomplete datasets. CONCLUSION: Research opportunities exist across all points of contact between stroke patients and ambulance services, but randomisation and consent remain novel. Early collaboration and engagement between trialists and ambulance services will alleviate some of the complexities reported. REGISTRATION NUMBER: PROSPERO 2018CRD42018075803.

Mobile integrated health-community paramedicine programs' effect on emergency department visits: An exploratory meta-analysis.

INTRODUCTION: Mobile Integrated Health Community Paramedicine (MIH-CP) programs are designed to increase access to care and reduce Emergency Department (ED) and Emergency Medical Services (EMS) usage. Previous MIH-CP systematic reviews reported varied interventions, effect sizes, and a high prevalence of biased methods. We aimed to perform a meta-analysis on MIH-CP effect on ED visits, and to evaluate study designs' effect on reported effect sizes. We hypothesized biased methods would produce larger reported effect sizes. METHODS: We searched Pubmed, Embase, CINAHL, and Scopus databases for peer-reviewed MIH-CP literature from January 1, 2000, to July 24, 2021. We included all full-text English studies whose program met the National Associations of Emergency Medical Technicians definition, reported ED visits, and had an MIH-CP related intervention and outcome. We established risk ratios for each included study through interpreting the reported data. We performed a random-effects and cumulative meta-analysis of ED visit data, tests of heterogeneity, and a moderator analysis to assess for factors influencing the magnitude of observed effect. RESULTS: We identified 16 studies that reported ED visit data and included 12 in our meta-analysis. All studies were observational; 3 used matched controls, 6 pre-post controls, and 3 without controls. 7 studies' intervention were diversion/triage while 5 studies intervened with health education/home primary care services. Pooled risk ratio for our data set was 0.56 (95% confidence interval 0.42-0.74). Cumulative meta-analysis revealed that as of 2018 MIH-CP programs began to show consistent reductions in ED visits. Significant heterogeneity was seen among studies, with I-squared >90%. Moderator analysis showed reduced heterogeneity for matched-control studies. CONCLUSION: Our data revealed MIH-CP programs were associated with a reduced risk of ED visits. Study design did not have a statistically significant influence on effect size, though it did influence heterogeneity. We would recommend future studies continue to use high levels of control to produce reliable data with lower heterogeneity.
