Developing emotional preparedness and mental resilience through high-fidelity simulation: a 'bridge too far' for institutions teaching major trauma management and mass-casualty medicine?

BACKGROUND: Clinical acumen represents only part of being adequately equipped to attend a major incident. The emotive sights, sounds and smells of these dynamic environments are all-encompassing experiences, and responders must also be armed with the emotional preparedness to perform their clinical or managerial duties effectively, as well as the mental resilience to facilitate professional continuance. Despite this, limited training and a sparsity of evidence exists to guide developments within this domain. Historically, major incident training has focused on clinical theory acquisition, but irrespective of how comprehensive the learning materials, they are of little consequence if tandem steps to cultivate mental resilience and emotional preparedness are absent. High-Fidelity Simulation (HFS) has a growing reputation as an effective means of bridging important gaps between theory and practice. This pilot study aimed to measure student's self-reported perception of their readiness to respond to a major incident following a large-scale HFS. METHODS: Quantitative data was obtained from a sample of 108 students undertaking paramedic science, physician associate studies and adult nursing degree programmes. A bespoke questionnaire was developed to measure self-reported clinical acumen, mental and emotional preparedness. RESULTS: 91% of students agreed the combination of theoretical training and HFS provided made them feel clinically prepared to attend a real major incident; 86% agreed this experience had developed their mental resilience and 90% agreed that they felt emotionally prepared to attend a major incident. CONCLUSION: Within this pilot study, the blend of theoretical training and HFS contributed to self-reported clinical acumen, mental and emotional preparation, in learners training to work in disaster environments or emergency medicine settings.

Paramedics as Researchers: A Systematic Review of Paramedic Perspectives of Engaging in Research Activity From Training to Practice.

BACKGROUND: The need for a stronger evidence-base in paramedicine has precipitated a rapid development of prehospital research agendas. Paramedics are increasingly involved in research, leading to changes in their role. Yet, the integration of research responsibilities has proven to be challenging, resulting in varying attitudes and levels of engagement. OBJECTIVE: This systematic review aimed to explore paramedics' views and experiences of research as researchers during training and within practice. METHODS: A systematic search was performed across six databases. Qualitative empirical peer-reviewed articles that discussed paramedic perspectives on engaging with research activity were included. Of 10,594 articles identified initially, 11 were included in the final synthesis after quality appraisal. Data were extracted and subjected to narrative synthesis. RESULTS: The following four themes were identified: motivation to engage, moral dilemmas, structural issues within the profession, and reflections on trial involvement. Attitudes toward research, understanding of related concepts, and the drive for patient benefit were interwoven core issues. CONCLUSIONS: Research was highly valued when links to patient benefit were obvious, however, this review highlights some cultural resistance to research, particularly regarding informed consent and changes to standard practice. Paramedic research methods training should provide structured opportunities to explore concerns and emphasize the role of research in developing a high-quality evidence base to underpin safe practice. Currently, there is inadequate organizational support for paramedics to engage effectively in research activity, with minimal allocations of time, training, and remuneration. Without properly integrating research activity into the paramedic role, their capacity to engage with research activity is limited.

The impact of the COVID-19 pandemic on transfers between long-term care and emergency departments across Alberta.

BACKGROUND: Long-term care (LTC) was overwhelmingly impacted by COVID-19 and unnecessary transfer to emergency departments (ED) can have negative health outcomes. This study aimed to explore how the COVID-19 pandemic impacted LTC to ED transfers and hospitalizations, utilization of community paramedics and facilitated conversations between LTC and ED physicians during the first four waves of the pandemic in Alberta, Canada. METHODS: In this retrospective population-based study, administrative databases were linked to identify episodes of care for LTC residents who resided in facilities in Alberta, Canada. This study included data from January 1, 2018 to December 31, 2021 to capture outcomes prior to the onset of the pandemic and across the first four waves. Individuals were included if they visited an emergency department, received care from a community paramedic or whose care involved a facilitated conversation between LTC and ED physicians during this time period. RESULTS: Transfers to ED and hospitalizations from LTC have been gradually declining since 2018 with a sharp decline seen during wave 1 of the pandemic that was greatest in the lowest-priority triage classification (CTAS 5). Community paramedic visits were highest during the first two waves of the pandemic before declining in subsequent waves; facilitated calls between LTC and ED physicians increased during the waves. CONCLUSIONS: There was a reduction in number of transfers from LTC to EDs and in hospitalizations during the first four waves of the pandemic. This was supported by increased conversations between LTC and ED physicians, but was not associated with increased community paramedic visits. Additional work is needed to explore how programs such as community paramedics and facilitated conversations between LTC and ED providers can help to reduce unnecessary transfers to hospital.

Role identities of emergency medical services personnel and their associations with intention to leave the profession.

BACKGROUND: The scope of emergency medical services (EMS) has expanded from the urgent care of emergency patients to on-call healthcare services provided in the field with a holistic view of the patient's wellbeing. This challenges EMS to find solutions to cover all demands, while simultaneously setting high skill requirements for EMS personnel. Understanding personnel is a critical element in developing functional and resistant EMS. The aim of this study was to investigate how Finnish EMS personnel emphasize the Emergency Medical Services Role Identity Scale aspects of caregiving, thrill-seeking, duty, and capacity; and if these role identities are associated with intention to leave the profession. METHODS: We conducted a cross-sectional survey (N = 616, 52% women, mean age 32.9 years). Data were collected through social media platforms and analyzed with means, standard deviations, Mann-Whitney U-tests, Kruskal-Wallis H-tests, and binary logistic regression analyses. RESULTS: Our results indicate that capacity is the most emphasized aspect among EMS personnel, and at the same time, it increases intention to leave EMS. Capacity was followed by caregiving, with no association with intention to leave. Duty and thrill-seeking were the least emphasized and were negatively associated with intention to leave. Additionally, there were also other factors that were associated with emphasizing EMS-RIS aspect and intention to leave. CONCLUSION: Capacity stands out most strongly in analysis being at the core of the role identity of EMS personnel and was associated with a higher likelihood of leaving intentions. Several other factors were also associated with the intention to leave. Future studies should examine the exact dimensions of capacity that are considered important among EMS personnel and why factors such as work experience are associated with intentions to leave.

Patient experience of non-conveyance in the EMS of Southwest Finland: a descriptive survey study.

BACKGROUND: Emergency Medical Services are dispatched more frequently than before. However, many non-urgent patients do not need ambulance transportation to a healthcare facility after evaluation and treatment on scene. This study explored the experiences of non-conveyed patients. Our research questions were: (1) How have non-conveyed patients experienced the service received from EMS? (2) Does a patient's age, gender, or time of the emergency call impact the patient's experience? METHODS: This descriptive survey study examined non-conveyed Emergency Medical Services patients in the Wellbeing Services County of Southwest Finland. The study period was from March 1, 2023, to March 31, 2023. The study population was 1017. They received a questionnaire that was sent by mail. The questionnaire was formed based on questions previously used in four different questionnaires. We received 247 answers (24.3% response rate). Percentages, medians with interquartile ranges, and non-parametric tests were used in the descriptive analyses. RESULTS: Non-conveyed patients were very satisfied with the paramedics' expertise and behavior, their ability to meet their individual needs, the sense of safety provided by the paramedics, and the instructions given to the patients. Time to receive help (19% rated 3 or less on a scale from 1 to 5), how paramedics introduced themselves (16.5%), and satisfaction with non-conveyance decisions (14.6%) were more frequently rated lower than other areas. Further, pain management stood out in the less favorable evaluations. Still, patients' experiences of the service were positive. The age group, gender, or time of the emergency call were not associated with patient experience. CONCLUSIONS: Patients were very satisfied with the paramedics' interpersonal skills. A more focused approach to pain management and developing EMS to ensure faster patient outreach and clearer explanations of non-conveyance decisions could further enhance the patient experience.

Exploring paramedic perspectives on emergency medical service (EMS) delivery in Alberta: a qualitative study.

PURPOSE: Emergency Medical Services (EMS) in Alberta are facing critical challenges. This qualitative study aims to describe and understand the frontline perspective regarding system level issues and propose provider-informed policy recommendations. METHODS: 19 semi-structured one-on- one interviews were conducted with Primary or Advanced Care Paramedics (PCP/ACP) across Alberta. Participants were asked to share their perspectives, experiences and recommendations in relation to EMS response times and the working environment. Interviews were analyzed using thematic analysis to identify themes and subthemes. RESULTS: Two core themes were identified as areas of concern: poor response times and the EMS working environment, which each influence and impact the other. Within response times, paramedics highlighted specific difficulties with ED offloading, a lack of resources, low-acuity calls, and rural challenges. In terms of the EMS working environment, four subthemes were apparent including attrition, unhealthy culture, organizational barriers and the need for paramedic empowerment. Providers made many recommendations including creating and expanding emergency mobile integrated health (MIH) branches, sharing 811 and 911 responses, and enforcing ED target offload times amongst other suggestions. CONCLUSIONS: While response times are a key and highly visible problem, there are many critical factors like the EMS working environment that degrade patient care and cause concern amongst frontline practitioners. Multifaceted policy changes are to be explored to reduce disfunction within EMS services, enhance the well-being of the workforce and deliver improved patient care. Specific EMS-oriented policies are important for moving forward to reduce transfers to EDs, but the broader health system which is over capacity is causing downstream effects into EMS must be addressed by government and health administrators.

Perception of Personal Participation of the Nurses in Resuscitation Procedures: A Qualitative Study.

Background and Objectives: Resuscitation is one of the most stressful tasks in emergency medicine. The participation of nurses in this procedure can have specific effects on them. In this research, we wanted to find out what these effects are. Materials and Methods: A qualitative approach by conducting semi-structured interviews was used, and a thematic data analysis of the recorded interviews was carried out. The collected data were transcribed verbatim, with no corrections to the audio recordings. The computer program ATLAS.ti 22 was used for the qualitative data analysis. Results: Eleven male registered nurses were interviewed, with an average of 18.5 years of experience working in a prehospital environment (max. 32/min. 9). A total of 404 min of recordings were analyzed, and 789 codes were found, which were combined into 36 patterns and 11 themes. As the most stressful situations, the interviewees pointed out the resuscitation of a child, familiar persons, conflicts with the environment, conflicts within the resuscitation team, nonfunctioning or insufficient equipment, complications during resuscitation, and resuscitating a person only for training. As positive effects, the interviewees cited successful resuscitations or their awareness that, despite an unsuccessful resuscitation, they did everything they could. Conclusions: Participation in these interventions has a specific positive or negative impact on the performers. The interviewees shared the opinion that they can cope effectively with the adverse or stressful effects of resuscitation. Yet, despite everything, they allow the possibility of subconscious influences of this intervention on themselves.

Comparison of Prehospital Assessment by Paramedics and In-Hospital Assessment by Physicians in Suspected Stroke Patients: Results From 2 Prospective Cohort Studies.

BACKGROUND: It is unknown if ambulance paramedics adequately assess neurological deficits used for prehospital stroke scales to detect anterior large-vessel occlusions. We aimed to compare prehospital assessment of these stroke-related deficits by paramedics with in-hospital assessment by physicians. METHODS: We used data from 2 prospective cohort studies: the LPSS (Leiden Prehospital Stroke Study) and PRESTO study (Prehospital Triage of Patients With Suspected Stroke). In both studies, paramedics scored 9 neurological deficits in stroke code patients in the field. Trained physicians scored the National Institutes of Health Stroke Scale (NIHSS) at hospital presentation. Patients with transient ischemic attack were excluded because of the transient nature of symptoms. Spearman rank correlation coefficient (rs) was used to assess correlation between the total prehospital assessment score, defined as the sum of all prehospital items, and the total NIHSS score. Correlation, sensitivity and specificity were calculated for each prehospital item with the corresponding NIHSS item as reference. RESULTS: We included 2850 stroke code patients. Of these, 1528 had ischemic stroke, 243 intracranial hemorrhage, and 1079 stroke mimics. Correlation between the total prehospital assessment score and NIHSS score was strong (rs=0.70 [95% CI, 0.68-0.72]). Concerning individual items, prehospital assessment of arm (rs=0.68) and leg (rs=0.64) motor function correlated strongest with corresponding NIHSS items, and had highest sensitivity (arm 95%, leg 93%) and moderate specificity (arm 71%, leg 70%). Neglect (rs=0.31), abnormal speech (rs=0.50), and gaze deviation (rs=0.51) had weakest correlations. Neglect and gaze deviation had lowest sensitivity (52% and 66%) but high specificity (84% and 89%), while abnormal speech had high sensitivity (85%) but lowest specificity (65%). CONCLUSIONS: The overall prehospital assessment of stroke code patients correlates strongly with in-hospital assessment. Prehospital assessment of neglect, abnormal speech, and gaze deviation differed most from in-hospital assessment. Focused training on these deficits may improve prehospital triage.

Addressing the challenges facing the paramedic profession in the United Kingdom.

BACKGROUND: The paramedic profession within the United Kingdom has been evolving at pace over the last 20 years. While they are most associated with their work in ambulance services, paramedics are now found throughout a range of clinical and academic settings. SOURCES OF DATA: Literature Review. AREAS OF AGREEMENT: Despite emergence of the paramedic across the healthcare workforce, the understanding and awareness of the professional role and capabilities is poor. This could be due to a lack of representation within senior leadership roles and within health and social care policy. AREAS OF CONTROVERSY: Understanding of the paramedic professional identity, from a philosophical and sociological perspective, remains incomplete. GROWING POINTS: A challenge for the future is to explore how the paramedic role can continue to develop across a range of clinical settings, while retaining its sui generis professional identity. AREAS TIMELY FOR DEVELOPING RESEARCH: Research to establish perspectives of and about the paramedic profession may assist in developing an understanding of identity and its place within the wider healthcare workforce.

A participatory ergonomics intervention to re-design work and improve the musculoskeletal health of paramedics: protocol for a cluster randomised controlled trial.

BACKGROUND: In this paper, we present the protocol for a cluster randomised controlled trial to evaluate the effectiveness and implementation of a participative risk management intervention to address work-related musculoskeletal disorders (WMSDs). The aims of the study include to evaluate the implementation process and the impact of the intervention on work related musculoskeletal pain and discomfort and exposure to physical and psychosocial hazards in paramedics over a 12-month period. METHODS: The intervention in this study is to implement A Participative Hazard Identification and Risk Management (APHIRM) toolkit in an ambulance service. Eighteen work groups containing eligible participants (registered paramedics) will be randomised into the intervention or wait-list control arm in one of three rolling recruitment periods. The APHIRM toolkit survey will be offered at baseline and 12 months later, to all current eligible participants in each work group allocated to the trial. The intervention work groups will receive the remainder of the APHIRM toolkit procedures. Identifying data about individual participants will not be collected in the survey, to protect participant privacy and encourage participation. Changes in primary (musculoskeletal pain and discomfort) and secondary (exposure to physical and psychosocial hazards at work) outcomes measured in the survey will be analysed comparing the baseline and follow up response of the cluster. A process evaluation is included to analyse the implementation and associated barriers or facilitators. DISCUSSION: This study is important in providing a comprehensive approach which focusses on both physical and psychosocial hazards using worker participation, to address WMSDs, a well-known and significant problem for ambulance services. The effectiveness of the intervention in work groups will be rigorously evaluated. If significant positive results are observed, the intervention may be adopted in ambulance services, both nationally and internationally. TRIAL REGISTRATION: ISRCTN77150219. Registered 21 November 2021.

Raring to go? 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.

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.

Decision on non-conveyance of patients suspected of COVID-19 in a novel arrangement with assessment visits by paramedics at home.

BACKGROUND: During the first weeks of the outbreak of the coronavirus disease 2019 (COVID-19), the North Denmark emergency medical services authorised paramedics to assess patients suspected of COVID-19 at home, and then decide if conveyance to a hospital was required. The aim of this study was to describe the cohort of patients who were assessed at home and their outcomes in terms of subsequent hospital visits and short-term mortality. METHODS: This was a historical cohort study in the North Denmark Region with consecutive inclusion of patients suspected of COVID-19 who were referred to a paramedic's assessment visit by their general practitioner or an out-of-hours general practitioner. The study was conducted from 16 March to 20 May 2020. The outcomes were the proportion of non-conveyed patients who subsequently visited a hospital within 72 hours of the paramedic's assessment visit and mortality at 3, 7 and 30 days. Mortality was estimated using a Poisson regression model with robust variance estimation. RESULTS: During the study period, 587 patients with a median age of 75 (IQR 59-84) years were referred to a paramedic's assessment visit. Three of four patients (76.5%, 95% CI 72.8;79.9) were non-conveyed, and 13.1% (95% CI 10.2;16.6) of the non-conveyed patients were subsequently referred to a hospital within 72 hours of the paramedic's assessment visit. Within 30 days from the paramedic's assessment visit, mortality was 11.1% [95% CI 6.9;17.9] among patients directly conveyed to a hospital and 5.8% [95% CI 4.0;8.5] among non-conveyed patients. Medical record review revealed that deaths in the non-conveyed group had happened among patients with 'do-not-resuscitate' orders, palliative care plans, severe comorbidities, age ≥ 90 years or nursing home residents. CONCLUSIONS: The majority (87%) of the non-conveyed patients did not visit a hospital for the following three days after a paramedic's assessment visit. The study implies that this newly established prehospital arrangement served as a kind of gatekeeper for the region's hospitals in regard to patients suspected of COVID-19. The study also demonstrates that implementation of non-conveyance protocols should be accompanied by careful and regular evaluation to ensure patient safety.

Assessment of frailty by paramedics using the clinical frailty scale - an inter-rater reliability and accuracy study.

BACKGROUND: Frailty assessment by paramedics in the prehospital setting is understudied. The goals of this study were to assess the inter-rater reliability and accuracy of frailty assessment by paramedics using the Clinical Frailty Scale (CFS). METHODS: This was a cross-sectional study with paramedics exposed to 30 clinical vignettes created from real-life situations. There was no teaching intervention prior to the study and paramedics were only provided with the French version of the CFS (definitions and pictograms). The primary outcome was the inter-rater reliability of the assessment. The secondary outcome was the accuracy, compared with the expert-based assessment. Reliability was determined by calculating an intraclass correlation coefficient (ICC). Accuracy was assessed through a mixed effects logistic regression model. A sensitivity analysis was carried out by considering that an assessment was still accurate if the score differed from no more than 1 level. RESULTS: A total of 56 paramedics completed the assessment. The overall assessment was found to have good inter-rater reliability (ICC = 0.87 [95%CI 0.81-0.93]). The overall accuracy was moderate at 60.6% (95%CI 54.9-66.1) when considering the full scale. It was however much higher (94.8% [95%CI 92.0-96.7] when close assessments were considered as accurate. The only factor associated with accurate assessment was field experience. CONCLUSION: The assessment of frailty by paramedics was reliable in this vignette-based study. However, the accuracy deserved to be improved. Future research should focus on the clinical impact of these results and on the association of prehospital frailty assessment with patient outcomes. REGISTRATION: This study was registered on the Open Science Framework registries ( https://doi.org/10.17605/OSF.IO/VDUZY ).

Less is more - The Finnish Prehospital Stroke Scale prospective validation.

OBJECTIVES: The current bifurcation of the acute stroke care pathway requires prehospital separation of strokes caused by large vessel occlusion. The first four binary items of the Finnish Prehospital Stroke Scale (FPSS) identify stroke in general, while the fifth binary item alone identifies stroke due to large vessel occlusion. The straightforward design is both easy for paramedics and statistically beneficial. We implemented FPSS based Western Finland Stroke Triage Plan, including medical districts of a comprehensive stroke center and four primary stroke centers. PATIENTS AND METHODS: The prospective study population was consecutive recanalization candidates transported to the comprehensive stroke center within the first six months of implementing the stroke triage plan. Cohort 1 consisted of n=302 thrombolysis- or endovascular treatment candidates transported from the comprehensive stroke center hospital district. Cohort 2 comprised ten endovascular treatment candidates transferred directly to the comprehensive stroke center from the medical districts of four primary stroke centers. RESULTS: In Cohort 1, FPSS sensitivity for large vessel occlusion was 0.66, specificity 0.94, positive predictive value 0.70, and negative predictive value 0.93. Of the ten Cohort 2 patients, nine had large vessel occlusion, and one had an intracerebral hemorrhage. CONCLUSIONS: FPSS is straightforward enough to be implemented in primary care services to identify candidates for endovascular treatment and thrombolysis. When used by paramedics, it predicted two-thirds of large vessel occlusions with the highest specificity and positive predictive value reported to date.

Nonurgent Pediatric Interhospital Transfers: A Narrative Enquiry of Nurses' Experiences in Australia.

INTRODUCTION: This study aimed to explore nonurgent pediatric interhospital transfers through the lens of nurses' experiences and perceptions when undertaking these transfers. METHODS: Using a narrative inquiry approach, data were collected via semistructured interviews with registered nurses (N = 7) who had experience undertaking patient transfers between nonurgent low-acuity and urgent high-acuity hospital settings. RESULTS: Findings established the following 8 themes: ensuring transfer preparation for risk mitigation, practicing confident advocacy, being accountable for risk mitigation of the deteriorating patient during transfer, maintaining standardized procedure, using training and mentorship to support confidence, maintaining interhospital and intrahospital relationships, recognizing the significance of transfer on families, and acknowledging the burden of transfer and delay. DISCUSSION: By exploring the stories and experiences of emergency nurses who undertake pediatric interhospital transfers, a deep investigation of the risks and challenges has been described, an area often underrepresented in the literature. Findings from this study highlight important learnings for pediatric interhospital transfer that add value to the wider body of evidence.

Paramedics' experiences and educational needs when participating end-of-life care at home: A mixed method study.

BACKGROUND: Paramedics face end-of-life care patients during emergency calls and more recently through planned protocols. However, paramedics experiences and educational needs concerning preplanned end-of-life care at home remain largely unknown. AIM: To describe experiences and educational needs of the paramedics included in the end-of-life care protocol. DESIGN: A mixed method study with a questionnaire including open ended questions and numeric evaluations on a Likert scale. SETTING/PARTICIPANTS: The questionnaire was delivered to and answered by all the 192 paramedics working in North Karelia fire and rescue department during the time of the data collection in 2017. RESULTS: Over 80% of the paramedics agreed that the protocol helped them to take care of the patients and to improve the quality of end-of-life care. Visits to the patients were considered useful and the end-of-life care as a meaningful work by 76.5% and 62.5% of the paramedics, respectively. The paramedics expressed challenges in psychosocial aspects, communication, symptom management, and their role in end-of-life care. Encountering and communication with the families as well as managing the most common symptoms were emphasized as educational needs. Using a patient controlled analgesia device emerged as an example of practical educational aspect. CONCLUSIONS: Paramedics considered end-of-life care at home meaningful but called for more competency in supporting and encountering the families and in symptom management. Our results can be utilized when developing end-of-life care protocols and education for the paramedics. Patients' and families' views on the paramedics' participation in end-of-life care should be evaluated in the future.

"House Calls" by Mobile Integrated Health Paramedics for Patients with Heart Failure: A Feasibility Study.

Background: Early readmissions following hospital discharge for heart failure (HF) remain a major concern. Among the various strategies designed to reduce readmissions, home evaluations have been observed to have a favorable impact. We assessed the feasibility of integrating community paramedics into the outpatient management of HF patients. Methods: Selected paramedics completed an educational HF curriculum. These Mobile Integrated Health Paramedics (MIHP) performed scheduled home visits 2- and 15-days post-discharge for patients with Stage C HF (Phase I) and patients with Stage D HF (Phase II). Facilitated by a Call Center, a process was created for performing urgent MIHP house calls within 60 minutes of a medical provider's request. A HF specialist, with an on-call emergency department command physician, could order an intravenous diuretic during home visits. During each phase of the study the incidence of 30-day HF readmissions, 30-day all-cause readmissions, emergency room evaluations, unplanned office encounters, as well as any adverse events were prospectively documented. Results: Collaborative relationships between our hospital network and local EMS organizations were created. There were 82 MIHP home visits. Eight patients received urgent home evaluations within 60-minutes post-request, one requiring transport to an ED. The incidence of all-cause 30-day readmissions in 20 Stage C and 20 Stage D patients was 15% and 40%, respectively. There were no adverse events attributable to the MIHP house calls. Conclusions: It is feasible to integrate MIHPs into the outpatient management of HF. Signals of effectiveness for reducing early readmissions were observed. Obstacles to creating an effective paramedic "House Calls" program were identified. A randomized trial is required to assess the value of this care process and its impact on early readmissions in patients with Stage C and Stage D HF.

Survival after Resuscitated Out-of-Hospital Cardiac Arrest in Patients with Paramedic-Identified ST-Segment Elevation Myocardial Infarction Treated with Primary Percutaneous Coronary Intervention.

Background: ST-segment elevation myocardial infarction (STEMI) is a common cause of out-of-hospital cardiac arrest (OHCA). For these patients, urgent angiography and revascularization is an important treatment goal. There is a lack of data on the prognosis of STEMI patients after OHCA, who are diagnosed and treated by paramedics prior to hospital transport for primary percutaneous coronary intervention (PCI). Methods: Included were adult STEMI patients identified and treated by paramedics in Queensland (Australia) from January 2016 to December 2019, transported to a hospital for primary PCI, and receiving primary PCI. Patients were grouped into those with resuscitated OHCA and those without OHCA. Clinically-important time intervals, angiographic and clinical profiles, and survival were described. Results: Patients with OHCA had longer time intervals from prehospital STEMI identification to reperfusion than those without OHCA (median 97 versus 87 mins, p = 0.001). The former had higher rates of cardiac arrhythmia history (50.5 versus 12.4%, p < 0.001), classified low left ventricular ejection fraction on admission (64.9 versus 50.1%, p = 0.006), and cardiogenic shock (5.2 versus 1.2%, p = 0.011) than the latter. A significantly higher proportion of patients with OHCA had multiple diseased vessels (16.9 versus 8.3%, p = 0.005). In-hospital, 30-day, and one-year mortality was low, being 4.1%, 4.1% and 5.2%, respectively, for STEMI patients with OHCA. The corresponding figures for those without OHCA were 1.6%, 1.8% and 3.3%, respectively. Conclusions: Survival in paramedic-identified STEMI patients treated with primary PCI following OHCA resuscitation was high. Rapid angiography and reperfusion are critical in these patients.

Early risk assessment in patients with suspected NSTE-ACS; a retrospective cohort study.

INTRODUCTION: Chest pain is among the most common reasons for Emergency Department (ED) presentation, while most patients should be considered low risk for Acute Coronary Syndrome (ACS). Management of these patients places a significant burden on our health care system. Various risk scores have been developed to facilitate the triage of patients with chest pain. However, it remains unclear which score performs best in identifying low risk patients, in various settings. The aim of this study was to determine which risk score performs best in ruling out non-ST elevation ACS (NSTE-ACS). METHODS: Data was collected from all patients >18 years presenting to the ED between 01 and 01-2019 and 01-07-2019, if they were suspected of NSTE-ACS. Primary endpoint was NSTE-ACS during presentation to the ED or hospitalization, according to the 2020 ESC guidelines. In a secondary analysis we determined the number low-risk patients, at set safety levels of 95% and 98%. RESULTS: A total of 536 patients were included, 192 (35.9%) were admitted to the hospital and NSTE-ACS occurred in 134 of 536 patients (25.0%). When areas under the curve (AUC) were compared, pre-HEART (0.869; CI 0.835-0.903), T-MACS (0.862; CI 0.825-0.898) and HEART (0.850; CI 0.815-0.885) performed best. At a safety level of 98%, the HEART score was the best performing risk score and identified 28.9% of patients as low risk, and missed 0 cases of NSTE-ACS. Followed by the pre-HEART score, which identified 18.3% of all patients as low risk, and missed 0% of NSTE-ACS. CONCLUSIONS: The newly developed pre-HEART score is both practical and has accurate diagnostic properties, closely followed by the HEART score, and T-MACS. New pre-hospital risk scores are promising and much needed. Future studies should focus on the usage of pre-hospital scores for triage of patients with chest pain, in order to reduce the burden on emergency health care.

Suicide crisis calls to emergency services: Cohort profile and findings from a data linkage study in Queensland, Australia.

BACKGROUND AND AIMS: Police and paramedics play a crucial role in responding to suicide crises in the community. However, little is known about the nature, extent, precipitating factors, pathways and outcomes of a suicide-related call to emergency services and what responses will most effectively and compassionately meet the needs of those in crisis. Partners in Prevention: Understanding and Enhancing First Responses to Suicide Crisis Situations (PiP) was established to address these knowledge gaps. METHODS: This article describes (1) the methodology used to construct the PiP dataset, a population-wide linked dataset that investigates the characteristics and health pathways of individuals in Queensland who were the subject of a suicide-related call to police or paramedics; and (2) preliminary findings on service demand, demographics and health services utilisation. RESULTS: We identified 219,164 suicide-related calls to Queensland Police Service or Queensland Ambulance Service that were made over the 3-year period 1 February 2014 to 31 January 2017. A total of 70,893 individuals were identifiable via records linkage. The cohort linked to more than 7,000,000 health records. We estimated that police or paramedics in Queensland received on average 209 calls per day, with increases year on year over the study period. Analysis of demographic data highlighted the heterogeneous nature of this cohort and important demographic variations between individuals in contact with police versus ambulance services. DISCUSSION: The PiP dataset provides a strong foundation for a multi-modal dataset that can be built on over time, both cross-sectionally and longitudinally. Further linkages to Medicare Benefits Schedule, Pharmaceutical Benefits Scheme and social care datasets are planned. CONCLUSION: Detailed population-level analysis that data linkage can provide is critical to improving understanding and responses to suicide crisis situations. The PiP study is a world first and provides a unique opportunity to improve responses to this public health problem.
