OBJECTIVE: Workplace violence (WPV) is an important issue in prehospital care, especially for emergency medical technicians ( EMTs) who are at increased risk of physical violence due to the nature of their work. This study aimed to shed light on the specific factors that contribute to the underlying causes of physical WPV in the prehospital context through direct experience and insight into the work of EMTs.
METHODS: Sequential explanatory mixed methods were applied in five western provinces of Iran from 2022 to 2023. In total, 358 EMTs that met the criteria for the quantitative phase were selected using a multi-stage clustering method. In the quantitative phase, the researchers used a questionnaire on workplace violence in the healthcare sector. Based on the results of the quantitative phase, 21 technicians who had experienced physical violence in the past 12 months were invited for in-depth interviews in the qualitative phase.
RESULTS: The average age of the EMTs was 33.96 ± 6.86 years, with an average work experience of 10.57 ± 6.80 years. More than half (53.6%) of the staff worked 24-hour shifts. In addition, most EMTs were located in urban bases (50.3%), and 78 (21.8%) reported having experienced physical violence. No significant correlations were found between the demographic characteristics of the technicians and the frequency of physical violence, except base location in the last 6 months. The qualitative study also created one theme (the complexity of WPV in the prehospital setting), four categories, and ten subcategories.
CONCLUSIONS: The study\'s results emphasize the need for comprehensive WPV factors in the prehospital setting. These factors can lead to identifying and improving strategies such as organizational support, improving communication and collaboration between responders, and training in de-escalation techniques. In addition, it is crucial to address the root causes of WPV such as poverty and lack of education in the community to create a safer and more supportive environment for patients and staff.

OBJECTIVE: The Scottish Highlands face unique prehospital care challenges due to population dispersity, mountainous terrain, seasonal weather, and higher trauma burden compared to the nearest Major Trauma Centres (MTCs) as highlighted by the Scottish Trauma Audit Group (STAG). Primary road/air transfer from scene to nearest designated MTC averages 1-5 hours, making prompt and informed utilisation of prehospital and in-hospital resources within the Highlands critical - comparative to other UK metropolitan regions where the trauma population majority lay within 20-45 minute transfer windows. This paper reviews the Highland pre-hospital immediate care and trauma (PICT) Team\'s trauma response through a retrospective review of PICT patient report forms (PRFs).
RESULTS: The analysis highlighted increased trauma response by the team in the nature of attended callouts and interventions utilised. Improving trends of patient outcomes, increased advanced analgesia and medico-surgical intervention utilisation, and relative increase of road traffic collision attendance and trauma-specific calls were noted.
CONCLUSIONS: Results highlight the Scottish Highlands\' trauma burden and PICT\'s added value; with increased trauma response and improving outcomes. Despite the rate and ratio of major trauma not reducing PICT Team utilisation has, potentially led to fewer patients over narrower geography at later stages in emergency calls accessing the enhanced care doctor and advanced physician team than was achieved previously.

BACKGROUND: Emergency medical services (EMS) systems are piloting interventions to respond to overdoses with additional services such as leave-behind naloxone and medication for opioid use disorder, but little is known about the perspectives of people who use drugs (PWUD) on these interventions being delivered by EMS during an overdose response.
METHODS: The Consolidated Framework for Implementation Research guided the development of data collection tools, the analytic strategy and the organisation of results. A community engaged method was used which included both academically trained researchers and community trained researchers who are also PWUD. This study used semi-structured interviews to gather data from 13 PWUD in King County, Washington in June 2022. Data were analysed using thematic analysis.
RESULTS: The people interviewed for this study viewed EMS distribution of leave-behind naloxone and field-based buprenorphine favourably. They viewed EMS facilitation of hepatitis C virus and HIV testing in the field less favourably and were concerned about stigmas associated with those results. Additional themes emerged regarding: the need for different approaches to post-overdose care; the need for new services, including post-overdose trauma counselling and an alternative destination to the emergency department; and the harms of law enforcement presence at overdose responses.
CONCLUSIONS: This study found strong support for leave-behind naloxone and field-initiated buprenorphine. Further training for EMS should include trauma-informed care and strategies to address burnout and increase compassion. Alternatives to the emergency department as a post-overdose destination are needed. These strategies should be considered by jurisdictions revising overdose response protocols.

UNASSIGNED: Extracorporeal cardiopulmonary resuscitation (eCPR) is a promising treatment that could improve survival for refractory out-of-hospital (OHCA) patients. Healthcare systems may choose to start eCPR in the prehospital setting to optimize time to eCPR initiation and decrease low-flow time. We used geospatial modeling to evaluate different eCPR catchment strategies for a forthcoming prehospital eCPR program in Houston, Texas.
UNASSIGNED: We studied OHCAs treated by the Houston Fire Department from 2013-2021. We included OHCA patients aged 18-65 years old with an initial shockable rhythm that did not have prehospital return of spontaneous circulation (ROSC). Based on the geolocation that each OHCA occurred, we used geospatial modeling to identify eCPR candidates using four mapping strategies based on distance/drive time from the eCPR center: 1) 15-minute drive time, 20-minute drive time, 10-mile drive distance, and 15-mile drive distance.
UNASSIGNED: Of 18,501 OHCAs during the study period, 881 met the eCPR inclusion criteria. Compared to non-eCPR candidates, eCPR candidates were younger (median age 52.3 years vs 62.7 years, p < 0.01) and had a higher proportion of males (76.6% v 59.8%, p < 0.01). Of eCPR candidate OHCAs, OHCAs occurred more frequently during the weekdays and the daytime, with 5:00 PM being the most common time. Using geospatial modeling and based on drive time, 219 OHCAs (24.9% of 881) were within a 15-minute drive, and 454 (51.5%) were within a 20-minute drive. Using drive distance, 383 eCPR candidates (43.5%) were within 10 miles, and 703 (79.8%) were within 15 miles.
UNASSIGNED: Using geospatial modeling, we demonstrated a process to estimate potential eCPR patient volumes for a geographic region. Geospatial modeling represents a viable strategy for healthcare systems to delineate eCPR catchment areas.

OBJECTIVE: Following recent changes to the German Narcotics Act, this article examines prehospital analgesia by paramedics using piritramide vs. nalbuphine + paracetamol.
METHODS: Prehospital analgesia administered by paramedics from the Fulda (piritramide) and Gütersloh (nalbuphine + paracetamol) emergency services was compared regarding pain intensity at the beginning and end of the mission, measured using the numeric rating scale (NRS). Additionally, an analysis of the resulting complications was carried out.
RESULTS: In this study 2429 administrations of analgesia were evaluated (nalbuphine + paracetamol: 1635, 67.3%, initial NRS: 8.0 ± 1.4, end of NRS: 3.7 ± 2.0; piritramide: 794, 32.7%, initial NRS: 8.5 ± 1.1, end of NRS: 4.5 ± 1.6). Factors influencing NRS change were initial NRS (regression coefficient, RC: 0.7075, 95% confidence interval, CI: 0.6503-0.7647, p < 0.001), treatment with nalbuphine + paracetamol (RC: 0.6048, 95% CI: 0.4396-0.7700, p < 0.001). Treatment with nalbuphine + paracetamol (n = 796 (48.7%)) compared to piritramide (n = 190 (23.9%)) increased the odds of achieving NRS < 4 (odds ratio, OR: 2.712, 95% CI: 2.227-3.303, p < 0.001). Complications occurred in n = 44 (5.5%) with piritramide and in n = 35 (2.1%) with nalbuphine + paracetamol. Risk factors for complications were analgesia with piritramide (OR: 2.699, 95% CI: 1.693-4.301, p < 0.001), female sex (OR: 2.372, 95% CI: 1.396-4.029, p = 0.0014), and age (OR: 1.013, 95% CI: 1.002-1.025, p = 0.0232).
CONCLUSIONS: Compared with piritramide, prehospital analgesia with nalbuphine + paracetamol has favorable effects in terms of analgesic efficacy and complication rates and should therefore be considered in future recommendations for paramedics.
UNASSIGNED: FRAGESTELLUNG: Angesichts der Änderungen des Betäubungsmittelgesetzes untersucht die vorliegende Arbeit die prähospitale Analgesie durch Notfallsanitäter*innen mittels Piritramid vs. Nalbuphin + Paracetamol.
UNASSIGNED: Alle prähospitalen Analgesien durch Notfallsanitäter*innen der Rettungsdienste der Kreise Fulda (Piritramid) sowie Gütersloh (Nalbuphin + Paracetamol) wurden im Hinblick auf die Schmerzstärke anhand der Numeric Rating Scale (NRS) zu Einsatzbeginn und -ende sowie die aufgetretenen Komplikationen ausgewertet.
UNASSIGNED: Insgesamt wurden 2429 Analgesien ausgewertet (Nalbuphin + Paracetamol: 1635 (67,3 %), NRS-initial: 8,0 ± 1,4, NRS-Einsatzende: 3,7 ± 2,0; Piritramid: 794 (32,7 %), NRS-initial: 8,5 ± 1,1, NRS-Einsatzende: 4,5 ± 1,6). Faktoren mit Einfluss auf eine NRS-Veränderung waren: initiale NRS (Regressionskoeffizient (RK): 0,7075, 95 %-Konfidenzintervall (95 %-KI): 0,6503–0,7647, p < 0,001) sowie Therapie mit Nalbuphin + Paracetamol (RK: 0,6048, 95 %-KI: 0,4396–0,7700, p < 0,001). Die Therapie mit Nalbuphin + Paracetamol (n = 796 (48,7 %)) im Vergleich zu Piritramid (n = 190 (23,9 %)) erhöhte die Chancen, eine NRS < 4 am Einsatzende aufzuweisen (Odds Ratio (OR): 2,712, 95 %-KI: 2,227–3,303, p < 0,001). Komplikationen traten bei Therapie mit Piritramid bei n = 44 (5,5 %) und bei Nalbuphin + Paracetamol bei n = 35 (2,1 %) auf. Risikofaktoren für Komplikationen waren Analgesie mit Piritramid (OR: 2,699, 95 %-KI: 1,693–4,301, p < 0,001), weibliches Geschlecht (OR: 2,372, 95 %-KI: 1,396–4,029, p = 0,0014) sowie das Lebensalter (OR: 1,013, 95 %-KI: 1,002–1,025, p = 0,0232).
CONCLUSIONS: Im Vergleich mit Piritramid weist die prähospitale Analgesie mit Nalbuphin + Paracetamol günstige Effekte im Hinblick auf analgetische Effektivität und Komplikationsraten auf und sollte in zukünftigen Empfehlungen für Notfallsanitäter*innen berücksichtigt werden.

UNASSIGNED: Emergency department (ED)-initiated buprenorphine has proven efficacy, but many patients are reluctant to begin this treatment. This study evaluated SafetyNet, a program using a 2-person, recovery coach and paramedic (RCP) intervention postoverdose to reduce subsequent opioid overdose, engage patients in medications for opioid use disorder (MOUD), and reduce illicit drug use.
UNASSIGNED: We conducted a prospective nonrandomized study in individuals who experienced opioid overdoses, received naloxone, but subsequently declined buprenorphine initiation in the ED. Each participant was followed by an RCP team that performed a brief negotiation interview (BNI) to motivate engagement in treatment, peer-recovery coaching to encourage recovery-related activities, and health education around medical concerns by trained paramedics. Participants were followed-up at 30 and 180 days. The primary hypothesized outcome was reduction in overdose events; the secondary hypothesized outcomes were engagement in MOUD and reduction in opioid positive urine tests.
UNASSIGNED: Eighty-one patients were enrolled and received BNIs; 45 (56%; 95% CI: 44-67) had at least 1 follow-up encounter. Twenty participants (25%; 95% CI: 16-36) had at least 1 overdose during follow-up. Fifty-five participants (68%; 95% CI: 57-78) were confirmed to have engaged in some form of medication treatment. Differences in subsequent overdose events (P = .95), engagement in MOUD (P = .49), and rates of opioid-positive urine toxicology rates within 30 days (P = .44) and between 31 and 180 days (P = .46) were not significantly different when comparing those who did and did not follow-up.
UNASSIGNED: There were no differences in rates of subsequent overdose, MOUD engagement, or positive urine toxicology screens in our intervention. However, 68% of participants engaged in outpatient MOUD, a treatment associated with fewer overdose events, particularly fatal ones. Substantial limitations occurred due to the COVID pandemic, and sample size estimates were not met. Further research is needed to investigate potential benefits of the SafetyNet program.

BACKGROUND: Emergency medical services (EMS) personnel must rapidly assess and transport patients with time-sensitive conditions to optimise patient outcomes. Serum lactate, a valuable in-hospital biomarker, has become more accessible in EMS settings through point-of-care (POC) testing. Although POC lactate levels are valuable in specific patient groups, its broader application in EMS remains unclear. This study assessed the additional predictive value of POC lactate levels in a general adult EMS population.
METHODS: This prospective observational study (March 2018 to September 2019) involved two EMS organisations in Västra Götaland, Sweden. Patients were triaged using the Rapid Triage and Treatment System (RETTS). POC lactate levels were measured using StatStrip Xpress devices. Non-consecutive patients who received EMS and were aged 18 years and above were available for inclusion if triaged into RETTS levels: red, orange, yellow, or green if respiratory rate of ≥ 22 breaths/min. Outcomes were adverse outcomes, including a time-sensitive diagnosis, sequential organ failure assessment (SOFA) score ≥ 2, and 30-day mortality. Statistical analyses included descriptive statistics, imputation, and regression models to assess the impact of the addition of POC lactate levels to a base model (comprising patient age, sex, presence of past medical conditions, vital signs, pain, EMS response time, assessed triage condition, and triage level) and a RETTS triage model.
RESULTS: Of 4,546 patients (median age 75 [57, 84] years; 49% male), 32.4% had time-sensitive conditions, 12.5% met the SOFA criteria, and 7.4% experienced 30-day mortality. The median POC lactate level was 1.7 (1.2, 2.5) mmol/L. Patients with time-sensitive conditions had higher lactate levels (1.9 mmol/L) than those with non-time-sensitive conditions (1.6 mmol/L). The probability of a time-sensitive condition increased with increasing lactate level. The addition of POC lactate marginally enhanced the predictive models, with a 1.5% and 4% increase for the base and RETTS triage models, respectively. POC lactate level as a sole predictor showed chance-only level predictive performance.
CONCLUSIONS: Prehospital POC lactate assessment provided limited additional predictive value in a general adult EMS population. However, it may be beneficial in specific patient subgroups, emphasizing the need for its judicious use in prehospital settings.

Background Palliative care aims to alleviate pain and distressing symptoms, affirm life, and offer support to patients and their caregivers. For many, the expressed preference is to die at home. As a result, there is growing recognition that paramedics can play an integral role at the end of life for symptom relief. Paramedic comfort with symptom management in the palliative care context is suspected, based on past work, to be higher for cancer as opposed to non-cancer life advanced disease. The objective of this study was to explore the paramedic management of patients with cancer and non-cancer advanced disease, using pain and breathlessness as key symptoms. Methods  A retrospective cohort study was conducted. Paramedic electronic patient care records were queried for calls with palliative goals of care between July 1, 2015, and June 30, 2016, in Nova Scotia, Canada, which was the first year of the Paramedics Providing Palliative Care program. A manual chart review of a subgroup of 100 consecutive charts was completed to gain deeper insight. A descriptive analysis was conducted to understand practice variation within this population.  Results The electronic query returned 1909 calls with a palliative approach. A total of 765 (40.1%) had cancer. The most common non-cancer disease category was respiratory. The top chief complaint was respiratory distress in both cancer and non-cancer populations. Medication was administered more often for pain (80%) compared to breathlessness (46.5%). Paramedics were more likely to call Medical Oversight Physicians for pain control advice. Post-treatment pain scores were documented infrequently. In the chart review, symptom management using the patient\'s own medications occurred in 17% of cases while an additional 5% of cases involved a combination of the patient\'s medications and paramedic service formulary. Conclusion  The non-cancer population was less likely to have a non-transport outcome. Opportunities for improvement of symptom management were noted for pain and particularly so for breathlessness. Increased comfort with a palliative approach in the non-cancer disease cohort as well as with this key symptom will be a key to the success of the program.

Traumatic brain injury (TBIs) necessitates a rapid and comprehensive medical response to minimize secondary brain injury and reduce mortality. Emergency medical services (EMS) clinicians serve a critical role in the management of prehospital TBI, responding during an initial phase of care with significant impact on patient outcomes. We used versions two and three of the Brain Trauma Foundation (BTF) Prehospital Guidelines for the Management of Traumatic Brain Injury and the NASEMSO National Model Clinical Guidelines to determine key elements for a TBI prehospital protocol and included common factors across sources such as recommendations concerning patient monitoring, hypoxia, hypotension, hyperventilation, cerebral herniation, airway management, hyperosmolar therapy, and transport destination. We then conducted a cross-sectional evaluation of publicly available statewide EMS clinical protocols in the US to determine the degree of alignment with national guidelines. We calculated descriptive statistics for each factor in the state protocols. Despite adoption of some evidence-based recommendations for a standard approach to the prehospital management of patients with TBI, we found significant variability in statewide EMS treatment protocols for management of severe TBI, especially in the recommended frequency of patient reassessment and for the management of suspected herniation. Most statewide protocols provided guidance regarding oxygenation, ventilation, and blood pressure management that aligned with evidence-based guidelines. While most protocols did address management of oxygenation and ventilation, one in four protocols had no specific guidance for managing hypoxia and only 31% of protocols recommended avoiding hyperventilation. For the management of suspected cerebral herniation, over half of statewide protocols recommended hyperventilation, whereas only 31% explicitly advised against hyperventilation regardless of TBI severity. Interestingly, 94% of protocols do not mention the use of hyperosmolar therapy for TBI patients, neither recommending use or avoidance of hyperosmolar therapy. In conclusion, we found inconsistent adoption of national recommendations in available statewide protocols for prehospital TBI management. We identified significant gaps and variation in statewide protocols regarding patient monitoring and reassessment, as well as in several key areas of severe TBI management.

OBJECTIVE: To study trends in incidence and outcome of patients with traumatic spinal cord injury (TSCI) in the Netherlands before, during and after implementation of the Advanced Trauma Life Support (ATLS®) and Pre-Hospital Trauma Life Support (PHTLS®)- Spinal Motion Restriction(SMR) protocol.
METHODS: In an observational database we studied national hospital admission and emergency department databases to analyse incidence rates and outcome of traumatic spinal cord injury and spinal fractures in the emergency department and in admittances in The Netherlands between 1986 and 2021.
RESULTS: A significant increase of 39% in TSCI in admitted patients with spinal fractures over the past 35 years (p < 0.001). This increase was especially prevalent in cervical spinal fractures (132%), while thoracic and lumbosacral spinal fractures showed a decrease in accompanied TSCI (64% and 88% respectively). The overall increase in spinal fractures was not significant. The duration of hospital admission decreased for spinal fractures without TSCI and with TSCI (66% and 56% respectively).
CONCLUSIONS: Since implementation of the SMR-protocol was aiming to limit TSCI in patients who suffered a spinal fracture, the increase in TSCI is an unexpected finding. Exact explanation for this increase is unclear and the contribution of the SMR-protocol is not fully understood due to confounders in the used datasets. Either way, the scientific evidence supporting this costly time- and labor-intensive SMR-protocol remains debated, along with evidence contradicting it. Therefore it stresses the need for clear, evidencebased reasoning for spinal immobilization according to ATLS, as this is currently lacking.
