Identifying prehospital trauma patients from ambulance patient care records; comparing two methods using linked data in New South Wales, Australia.

BACKGROUND: Linked datasets for trauma system monitoring should ideally follow patients from the prehospital scene to hospital admission and post-discharge. Having a well-defined cohort when using administrative datasets is essential because they must capture the representative population. Unlike hospital electronic health records (EHR), ambulance patient-care records lack access to sources beyond immediate clinical notes. Relying on a limited set of variables to define a study population might result in missed patient inclusion. We aimed to compare two methods of identifying prehospital trauma patients: one using only those documented under a trauma protocol and another incorporating additional data elements from ambulance patient care records. METHODS: We analyzed data from six routinely collected administrative datasets from 2015 to 2018, including ambulance patient-care records, aeromedical data, emergency department visits, hospitalizations, rehabilitation outcomes, and death records. Three prehospital trauma cohorts were created: an Extended-T-protocol cohort (patients transported under a trauma protocol and/or patients with prespecified criteria from structured data fields), T-protocol cohort (only patients documented as transported under a trauma protocol) and non-T-protocol (extended-T-protocol population not in the T-protocol cohort). Patient-encounter characteristics, mortality, clinical and post-hospital discharge outcomes were compared. A conservative p-value of 0.01 was considered significant RESULTS: Of 1 038 263 patient-encounters included in the extended-T-population 814 729 (78.5 %) were transported, with 438 893 (53.9 %) documented as a T-protocol patient. Half (49.6 %) of the non-T-protocol sub-cohort had an International Classification of Disease 10th edition injury or external cause code, indicating 79644 missed patients when a T-protocol-only definition was used. The non-T-protocol sub-cohort also identified additional patients with intubation, prehospital blood transfusion and positive eFAST. A higher proportion of non-T protocol patients than T-protocol patients were admitted to the ICU (4.6% vs 3.6 %), ventilated (1.8% vs 1.3 %), received in-hospital transfusion (7.9 vs 6.8 %) or died (1.8% vs 1.3 %). Urgent trauma surgery was similar between groups (1.3% vs 1.4 %). CONCLUSION: The extended-T-population definition identified 50 % more admitted patients with an ICD-10-AM code consistent with an injury, including patients with severe trauma. Developing an EHR phenotype incorporating multiple data fields of ambulance-transported trauma patients for use with linked data may avoid missing these patients.

Can the Emergency Medical Service (EMS) System Help in Improving the Healthcare Access - Evidence from Maharashtra EMS.

Background: For many people in the remote regions of India, medical help is inaccessible as 66% of rural Indians do not have access to critical medicine and 31% of the population travel more than 30 km seeking health care in rural India. Timely non-availability of doctors in healthcare facilities, especially in primary health centers (PHCs), leads to more dependency on the private healthcare practitioners for the out-patient department services. This needs immediate attention. Materials and Methods: The healthcare authority in Maharashtra has allowed doctors in 108 emergency ambulances to provide consulting services. The current study is based on the total consultations managed by the doctors on-board on the 108 ambulances in the state of Maharashtra in the years 2020, 2021, and 2022. The data are procured from the state-run Emergency Response Centre, and the analysis is done by using the basic statistical technique in MS Excel and SPSS16.0. Results: More than 9.35 lakh medical consultations were provided with an average 856 consultations per ambulance in the year 2022, showing a significant growth of 452% over the consultations in 2020. The base location of the 32% ambulance (298) in the PHCs has improved the round the clock accessibility in 16% of the total PHCs in the state of Maharashtra. Conclusion: The availability of the doctors in the state-run emergency ambulances for general healthcare services has improved the adherence of Indian Public Health Standards, and such practice must be examined for implementation in other states.

Development and internal validation of an algorithm for estimating mortality in patients encountered by physician-staffed helicopter emergency medical services.

BACKGROUND: Severity of illness scoring systems are used in intensive care units to enable the calculation of adjusted outcomes for audit and benchmarking purposes. Similar tools are lacking for pre-hospital emergency medicine. Therefore, using a national helicopter emergency medical services database, we developed and internally validated a mortality prediction algorithm. METHODS: We conducted a multicentre retrospective observational register-based cohort study based on the patients treated by five physician-staffed Finnish helicopter emergency medical service units between 2012 and 2019. Only patients aged 16 and over treated by physician-staffed units were included. We analysed the relationship between 30-day mortality and physiological, patient-related and circumstantial variables. The data were imputed using multiple imputations employing chained equations. We used multivariate logistic regression to estimate the variable effects and performed derivation of multiple multivariable models with different combinations of variables. The models were combined into an algorithm to allow a risk estimation tool that accounts for missing variables. Internal validation was assessed by calculating the optimism of each performance estimate using the von Hippel method with four imputed sets. RESULTS: After exclusions, 30 186 patients were included in the analysis. 8611 (29%) patients died within the first 30 days after the incident. Eleven predictor variables (systolic blood pressure, heart rate, oxygen saturation, Glasgow Coma Scale, sex, age, emergency medical services vehicle type [helicopter vs ground unit], whether the mission was located in a medical facility or nursing home, cardiac rhythm [asystole, pulseless electrical activity, ventricular fibrillation, ventricular tachycardia vs others], time from emergency call to physician arrival and patient category) were included. Adjusted for optimism after internal validation, the algorithm had an area under the receiver operating characteristic curve of 0.921 (95% CI 0.918 to 0.924), Brier score of 0.097, calibration intercept of 0.000 (95% CI -0.040 to 0.040) and slope of 1.000 (95% CI 0.977 to 1.023). CONCLUSIONS: Based on 11 demographic, mission-specific, and physiologic variables, we developed and internally validated a novel severity of illness algorithm for use with patients encountered by physician-staffed helicopter emergency medical services, which may help in future quality improvement.

Heat-related mortality and ambulance transport after a power outage in the Tokyo metropolitan area.

Background: Air conditioners can prevent heat-related illness and mortality, but the increased use of air conditioners may enhance susceptibility to heat-related illnesses during large-scale power failures. Here, we examined the risks of heat-related illness ambulance transport (HIAT) and mortality associated with typhoon-related electricity reduction (ER) in the summer months in the Tokyo metropolitan area. Methods: We conducted event study analyses to compare temperature-HIAT and mortality associations before and after the power outage (July to September 2019). To better understand the role of temperature during the power outage, we then examined whether the temperature-HIAT and mortality associations were modified by different power outage levels (0%, 10%, and 20% ER). We computed the ratios of relative risks to compare the risks associated with various ER values to the risks associated without ER. Results: We analyzed the data of 14,912 HIAT cases and 74,064 deaths. Overall, 93,200 power outage cases were observed when the typhoon hit. Event study results showed that the incidence rate ratio was 2.01 (95% confidence interval [CI] = 1.42, 2.84) with effects enduring up to 6 days, and 1.11 (95% CI = 1.02, 1.22) for mortality on the first 3 days after the typhoon hit. Comparing 20% to 0% ER, the ratios of relative risks of heat exposure were 2.32 (95% CI = 1.41, 3.82) for HIAT and 0.95 (95% CI = 0.75, 1.22) for mortality. Conclusions: A 20% ER was associated with a two-fold greater risk of HIAT because of summer heat during the power outage, but there was little evidence for the association with all-cause mortality.

Prehospital early warning scores for adults with suspected sepsis: the PHEWS observational cohort and decision-analytic modelling study.

Background: Guidelines for sepsis recommend treating those at highest risk within 1 hour. The emergency care system can only achieve this if sepsis is recognised and prioritised. Ambulance services can use prehospital early warning scores alongside paramedic diagnostic impression to prioritise patients for treatment or early assessment in the emergency department. Objectives: To determine the accuracy, impact and cost-effectiveness of using early warning scores alongside paramedic diagnostic impression to identify sepsis requiring urgent treatment. Design: Retrospective diagnostic cohort study and decision-analytic modelling of operational consequences and cost-effectiveness. Setting: Two ambulance services and four acute hospitals in England. Participants: Adults transported to hospital by emergency ambulance, excluding episodes with injury, mental health problems, cardiac arrest, direct transfer to specialist services, or no vital signs recorded. Interventions: Twenty-one early warning scores used alongside paramedic diagnostic impression, categorised as sepsis, infection, non-specific presentation, or other specific presentation. Main outcome measures: Proportion of cases prioritised at the four hospitals; diagnostic accuracy for the sepsis-3 definition of sepsis and receiving urgent treatment (primary reference standard); daily number of cases with and without sepsis prioritised at a large and a small hospital; the minimum treatment effect associated with prioritisation at which each strategy would be cost-effective, compared to no prioritisation, assuming willingness to pay £20,000 per quality-adjusted life-year gained. Results: Data from 95,022 episodes involving 71,204 patients across four hospitals showed that most early warning scores operating at their pre-specified thresholds would prioritise more than 10% of cases when applied to non-specific attendances or all attendances. Data from 12,870 episodes at one hospital identified 348 (2.7%) with the primary reference standard. The National Early Warning Score, version 2 (NEWS2), had the highest area under the receiver operating characteristic curve when applied only to patients with a paramedic diagnostic impression of sepsis or infection (0.756, 95% confidence interval 0.729 to 0.783) or sepsis alone (0.655, 95% confidence interval 0.63 to 0.68). None of the strategies provided high sensitivity (> 0.8) with acceptable positive predictive value (> 0.15). NEWS2 provided combinations of sensitivity and specificity that were similar or superior to all other early warning scores. Applying NEWS2 to paramedic diagnostic impression of sepsis or infection with thresholds of > 4, > 6 and > 8 respectively provided sensitivities and positive predictive values (95% confidence interval) of 0.522 (0.469 to 0.574) and 0.216 (0.189 to 0.245), 0.447 (0.395 to 0.499) and 0.274 (0.239 to 0.313), and 0.314 (0.268 to 0.365) and 0.333 (confidence interval 0.284 to 0.386). The mortality relative risk reduction from prioritisation at which each strategy would be cost-effective exceeded 0.975 for all strategies analysed. Limitations: We estimated accuracy using a sample of older patients at one hospital. Reliable evidence was not available to estimate the effectiveness of prioritisation in the decision-analytic modelling. Conclusions: No strategy is ideal but using NEWS2, in patients with a paramedic diagnostic impression of infection or sepsis could identify one-third to half of sepsis cases without prioritising unmanageable numbers. No other score provided clearly superior accuracy to NEWS2. Research is needed to develop better definition, diagnosis and treatments for sepsis.

Sepsis is a life-threatening condition in which an abnormal response to infection causes heart, lung or kidney failure. People with sepsis need urgent treatment. They need to be prioritised at the emergency department rather than waiting in the queue. Paramedics attempt to identify people with possible sepsis using an early warning score (based on simple measurements, such as blood pressure and heart rate) alongside their impression of the patient's diagnosis. They can then alert the hospital to assess the patient quickly. However, an inaccurate early warning score might miss cases of sepsis or unnecessarily prioritise people without sepsis. We aimed to measure how accurately early warning scores identified people with sepsis when used alongside paramedic diagnostic impression. We collected data from 71,204 people that two ambulance services transported to four different hospitals in 2019. We recorded paramedic diagnostic impressions and calculated early warning scores for each patient. At one hospital, we linked ambulance records to hospital records and identified who had sepsis. We then calculated the accuracy of using the scores alongside diagnostic impression to diagnose sepsis. Finally, we used modelling to predict how many patients (with and without sepsis) paramedics would prioritise using different strategies based on early warning scores and diagnostic impression. We found that none of the currently available early warning scores were ideal. When they were applied to all patients, they prioritised too many people. When they were only applied to patients whom the paramedics thought had infection, they missed many cases of sepsis. The NEWS2, score, which ambulance services already use, was as good as or better than all the other scores we studied. We found that using the NEWS2, score in people with a paramedic impression of infection could achieve a reasonable balance between prioritising too many patients and avoiding missing patients with sepsis.

Development and inter-rater reliability of a simple prehospital mobility score for use in emergency patients.

BACKGROUND: Mobility assessment enhances the ability of vital sign-based early warning scores to predict risk. Currently mobility is not routinely assessed in a standardized manner in Denmark during the ambulance transfer of unselected emergency patients. The aim of this study was to develop and test the inter-rater reliability of a simple prehospital mobility score for pre-hospital use in ambulances and to test its inter-rater reliability. METHOD: Following a pilot study, we developed a 4-level prehospital mobility score based of the question"How much help did the patient need to be mobilized to the ambulance trolley". Possible scores were no-, a little-, moderate-, and a lot of help. A cross-sectional study of inter-rater agreement among ambulance personnel was then carried out. Paramedics on ambulance runs in the North- and Central Denmark Region, as well as The Fareoe Islands, were included as a convenience sample between July 2020-May 2021. The simple prehospital mobility score was tested, both by the paramedics in the ambulance and by an additional observer. The study outcomes were inter-rater agreements by weighted kappa between the paramedics and between observers and paramedics. RESULTS: We included 251 mobility assessments where the patient mobility was scored. Paramedics agreed on the mobility score for 202 patients (80,5%). For 47 (18.7%), there was a deviation of one between scores, in two (< 1%) there was a deviation of two and none had a deviation of three (Table 1). Inter-rater agreement between paramedics in all three regions showed a kappa-coefficient of 0.84 (CI 95%: 0.79;0.88). Between observers and paramedics in North Denmark Region and Faroe Islands the kappa-coefficient was 0.82 (CI 95%: 0.77;0.86). CONCLUSION: We developed a simple prehospital mobility score, which was feasible in a prehospital setting and with a high inter-rater agreement between paramedics and observers.

"Mind the gap": An exploratory qualitative study of paramedics' experiences attending older adults who fall in Western Australia.

PURPOSE: To explore paramedics' experiences and perspectives about attending and managing older adults who had fallen. PROCEDURES: This qualitative, exploratory study used a purposive sample of paramedics in Western Australia. Participants had at least one year of clinical experience. Semi-structured interviews were undertaken. Data were analysed via an inductive thematic approach. FINDINGS: Fourteen paramedics were interviewed (Median age: 38 years, n = 5 females). The main theme identified that experiences were positive when attending patients with high-acuity medical problems or injuries following falls because binary decision-making (transport vs non-transport) was appropriate. Themes highlighted that decision-making for low-acuity falls attendances was a complex balance between 1) patient context, 2) risk management, 3) paramedic reactions, and 4) the lack of alternate referral pathways available. Experiences could be stressful and frustrating when attending falls call-outs for older adults with no injuries or medical problems. Participants concurred that when transport to hospital was not required there were no available, alternative pathways to refer onwards for appropriate health or social care. CONCLUSION: Attending low-acuity call-outs for falls was often frustrating and required complex decision-making, with gaps in services identified. Further exploration of alternative referral pathways for health care for pre-hospital management of adults who fall is required.

The role of emergency medical services in the management of in-hospital emergencies: Causes and outcomes of emergency calls - A descriptive retrospective register-based study.

BACKGROUND: Medical emergency teams (METs) are in place in some hospitals in Finland to respond to critical emergency events. However, in hospitals without dedicated METs, staff are instructed to call emergency medical services (EMS) to deal with emergencies. This study examined the reasons for calling EMS to hospitals and the outcomes of these calls. METHODS: Descriptive retrospective register-based study of the response and management of in-hospital emergencies by EMS in the wellbeing services county of Southwest Finland. Patient care reports of the EMS and those of the hospitals were analysed. RESULTS: In total, 138 medical emergencies managed by EMS were included in this study. 108 of these related to patients, and 25 related to hospital personnel. Cardiac arrest (n = 36) and a reduced level of consciousness (n = 29) were the most common in-hospital emergencies. In 68% of in-hospital emergencies managed by the EMS team, after calling 112, hospital personnel implemented various treatment measures. In 72% of cases, follow-up treatment was required. CONCLUSIONS: Hospital personnel are able to initiate medical measures in emergencies, even when no MET is available. Although EMS are important in responding to in-hospital emergencies, they seem to be performing the same role as METs.

Effect of urgency level on prehospital emergency transport times: a natural experiment.

Accurate estimation of ambulance transport time from the scene of incident to arrival at the emergency department (ED) is important for effective resource management and emergency care system planning. Further, differences in transport times between different urgency levels highlight the benefits of ambulance transports with highest urgency level in a setting where ambulances are allowed to not follow standard traffic rules. The objective of the study is to compare ambulance urgency level on the differences in estimates of ambulance transport times generated by Google Maps and the observed transport times in a prehospital setting where emergency vehicles have their own traffic laws. The study was designed as a natural experiment and register study. Ambulance transports dispatched with different levels of urgency (Level A and B) were included in the Central Denmark Region (a mixed urban and rural area) from March 10 to June 11, 2021. Ambulance transports for highest urgency level were compared to lowest urgency level with Google Maps estimated transport times as reference. We analyzed 1981 highest urgency level and 8.958 lowest urgency level ambulance transports. Google Maps significantly overestimated the duration of transports operating at highest level of urgency (Level A) by 1.9 min/10 km (95% CI 1.8; 2.0) in average and 4.8 min/10 km (95% CI 3.9; 5.6) for the first driven 10 km. Contrary, Google Maps significantly underestimated the duration of transports operating at lowest level of urgency (Level B) by -1.8 min/10 km (95% CI -2.1; -1.5) in average and -4.4 min/10 km (95% CI -5.4; -3.5) for the first driven 10 km. Google Maps systematically overestimates transport times of ambulance transports driven with Level A, the highest level of urgency in a setting where ambulances are allowed to not follow standard traffic rules. The results highlight the benefit of using urgency Level A and provide valuable information for emergency care management.

Team climate and job satisfaction in a mobile emergency service: a multilevel study / Clima en equipo y satisfacción laboral en un servicio de atención móvil de urgencia: estudio multinivel / Clima em equipe e satisfação no trabalho em um serviço de atendimento móvel de urgência: estudo multinível

Objective: to investigate the relationship between team climate and job satisfaction among professionals working in mobile pre-hospital care. Method: this is a quantitative, correlational study carried out in a mobile pre-hospital care service in the São Paulo Metropolitan Region. The participants were 95 professionals, allocated to 40 teams, who answered three questionnaires: sociodemographic/labor data, Team Climate Scale and S20/23 Job Satisfaction Scale. Descriptive statistics and multilevel linear models were used for the analysis, including moderation effects. The Backward method was used to ascertain the order of significance. Results: in the models, the relationships between satisfaction with hierarchical relationships and the factor "support for new ideas" moderated for men and "task orientation" for women were significant. For satisfaction with the physical environment, "working hours" and "participation in the team" were significant and, for intrinsic satisfaction, the regime, working hours and the factors "team objectives", "participation in the team" and "support for new ideas" remained significant, as did the moderation effect between length of service, "participation in the team" and "support for new ideas". Conclusion: team climate is influenced by job satisfaction in a heterogeneous way and the moderating effect of this relationship is associated with gender and length of service.

Produção de procedimentos pelo SAMU 192 no Brasil: performance, benchmarking e desafios / Implementation of procedures by the Mobile Emergency Care Service (SAMU 192) in Brazil: performance, benchmarking, and challenges

Resumo O objetivo deste artigo é descrever e analisar a produção de procedimentos realizados pelas centrais de regulação e recursos móveis do SAMU 192 entre 2015 e 2019, segundo frequência, indicadores de base populacional e produtividade diária, estabelecendo um indicador de performance. Estudo censitário, observacional e descritivo, realizado com dados de produção, extraídos do Sistema de Informações Ambulatoriais, complementados com dados do Instituto Brasileiro de Geografia e Estatística e do Ministério da Saúde. Os 116,8 milhões de procedimentos analisados decorrem de 28,5% de aumento no período enquanto a população coberta e os recursos móveis cresceram 9,7% e 14,4% respectivamente. Cada mil habitantes cobertos geraram 109,8 chamadas, resultando em 24,0 envios de recursos móveis anuais. Diariamente, unidades de suporte básico realizaram 3,3 atendimentos e 0,5 transporte, enquanto o suporte avançado realizou 2,7 atendimentos e 0,9 transporte. A produção de procedimentos excedeu o crescimento de população coberta, com variações entre estados, alta produção em áreas populosas, forte presença do suporte básico e elevação dos transportes, todavia a produtividade nacional mostrou-se inferior a internacional.

Abstract The scope of this article is to describe and analyze the production of approved procedures carried out by regulation centers and mobile resources of SAMU 192 between 2015 and 2019, according to frequency, population-based indicators, and daily productivity, to establish a performance indicator. It consisted of an observational and descriptive census study, with production data drawn from the Outpatient Information System, and population data from the Brazilian Institute of Geography and Statistics and information from the Ministry of Health. The 116.8 million procedures analyzed resulted from a 28.5% increase in the period, while the population covered and mobile resources grew by 9.7% and 14.4%, respectively. Every 1,000 inhabitants covered generated 109.8 calls, resulting in 24.0 mobile resource dispatches per year. Basic support units performed 3.3 consultations, and 0.5 transfers daily, while advanced support performed 2.7 consultations and 0.9 transfers. The production of procedures exceeded the increase in the population covered, with variations between states, high incidence in populated areas, a strong presence of basic support and an increase in transfers, although national productivity was seen to be lower than international productivity.

The Use of Prehospital Intensive Care Units in Emergencies-A Scoping Review.

BACKGROUND: Amidst a rising tide of trauma-related emergencies, emergency departments worldwide grapple with the challenges of overcrowding and prolonged patient wait times. Addressing these challenges, the integration of prehospital intensive care units has appeared as a promising solution, streamlining trauma care and enhancing patient safety. Nevertheless, the feasibility of such an initiative becomes murky when considered globally. This review delves into the intricacies of prehospital intensive care units' deployment for trauma care, scrutinizing their configurations, operational practices, and the inherent challenges and research priorities. METHODS: A scoping review was performed for eligible studies. The result was uploaded to the RAYYAN research platform, facilitating simultaneous evaluation of the studies by all researchers. RESULTS: A total of 42 studies were initially selected. Four studies were duplicates, and 25 studies were unanimously removed as irrelevant. The remaining studies (n = 13) were included in the review, and the outcomes were categorized into diverse subgroups. CONCLUSIONS: A country's emergency medical services must achieve specific milestones in education, competency, resource availability, and performance to effectively harness the potential of a prehospital intensive care unit. While certain nations are equipped, others lag, highlighting a global disparity in readiness for such advanced care modalities.

What are ambulance personnel experiences of sexual harassment and sexual assault in the workplace? A rapid evidence review.

INTRODUCTION: Sexual assault and harassment of ambulance personnel in the workplace is widespread. Prevention via body worn cameras and legal efforts have been positive, however improvement is still needed to ensure the protection of staff from the negative impact of sexual violence at work. METHODS: A rapid evidence review was conducted following the Cochrane Rapid Review guidance. MEDLINE and CINAHL Complete were searched from inception to February 2023. Screening and data extraction was conducted by one author and verified by the other. Included studies were appraised using a variety of critical appraisal checklists and a narrative synthesis was conducted. RESULTS: From 46 articles screened, 7 were included in the review representing 3994 ambulance personnel from Australia, Canada, the United States, the United Kingdom and South Korea. Seven themes were identified, including a need for more training, education and resources regarding sexual assault and harassment, differences in perpetrators, poor experiences with organisations, effects on victims outside the workplace, effects on victims within the workplace, barriers to reporting, and increased prevalence of sexual assault and harassment against women. CONCLUSION: The effect of sexual assault and harassment has far-reaching negative impact on victims' lives. More training and resources are recommended.

Developing a prehospital care service in a low-resource setting: Barriers and solutions.

Prehospital care (PHC) is critical to the comprehensive and effective functioning of a healthcare system. Given the disproportionate burden of both communicable and non-communicable diseases in low-income nations, its significance cannot be understated. In spite of this, many of these nations lack a comprehensive PHC system. Setting up a cost-effective PHC system in this environment can be difficult and necessitate a variety of stakeholders at various healthcare delivery system levels. Therefore, it is necessary to consider these anticipated barriers and identify feasible solutions for its execution. This will assist in creating a PHC system that is suited to the local needs and achieve sustainable and global health goals. This paper describes the challenges and solutions to establishing a prehospital care service in a low-resource setting.

Characteristics and Outcomes of Patient Transport to the Hospital by Emergency Medical Services (EMS); a Cross-sectional Study.

Introduction: To enhance the efficiency, it is essential to understand the patterns of service users and develop policies that facilitate effective personnel and resource management. This study aimed to compare the characteristic and outcomes of patients who were transferred to emergency department (ED) by emergency medical services (EMS) and patients transported by other means. Methods: This retrospective cross-sectional study was conducted at Srinagarind Hospital, Thailand, over a 5-year period from 2017-2021. The baseline characteristics, treatment modalities, and outcomes of patients who were transported to ED using EMS and Non-EMS were gathered and compared using STATA software. Results: The study included 15,501 patients with the median age of 51 (interquartile range (IQR): 23-71) years who were referred by EMS over the five-year period (51.72% male). EMS patients had significantly higher median age (51 (23 - 71) vs. 37 (21 - 60); p < 0.001) with male preference (p < 0.001). In the EMS group, the triage level 1 (need for resuscitation) was higher than the non-EMS group (p < 0.001), most of the patients referred following trauma (p < 0.001), and the frequency of cardiac arrest was considerably higher than non-EMS group (2.54% vs 0.05%; p < 0.001). Patients in the EMS group received a higher number of blood tests (p < 0.001), plain radiographic exams (p < 0.001), computerized tomography (CT) scans (p < 0.001), and complex procedures (p < 0.001) than the non-EMS group. The EMS group had a greater number of hospital admissions (p < 0.001) and intensive care unit (ICU) admissions (p < 0.001) compared to the non-EMS group. The EMS group exhibited a significantly higher mortality rate compared to the non-EMS group (p < 0.001). Conclusion: The population utilizing EMS services had higher median age, higher frequency of emergency cases and trauma related complaint, higher need for treatment interventions and imaging procedures, higher rate of hospital and ICU admissions, as well as higher rate of mortality compared to the non-EMS group.

Ambulance personnel use of coercion and use of safety belts in Norway.

BACKGROUND: Providing health care in a moving vehicle requires different considerations regarding safety than in other settings. Use of seatbelts are mandatory, and during ambulance transport patients are fastened to the stretcher with safety straps. However, patients who wriggle out of, or unfasten, their safety straps pose a threat to him/herself and escorting personnel in the ambulance compartment in case of an accident. To prevent harm, ambulance personnel sometimes restrain the patient or unfasten their own seatbelts to keep the patient safe on the stretcher. The prevalence of coercive measures, and the relationship between the use of mechanical restraints comparable to coercion and seatbelt use, are scarcely investigated. Use of coercion normally requires a specific statutory basis. However, coercive measures needed to ensure safety in a moving vehicle while providing healthcare is hardly discussed in the literature. The aim of this study is to explore the use of coercion in ambulance services, the use of safety belts among escorts in situations where they need to keep the patient calm during transportation, and to analyse the relationship between safety belt non-compliance and coercion in these situations. METHODS: This is a retrospective, cross-sectional study using a self-administered, online survey aiming to investigate the use of coercion and use of seatbelts during ambulance transport. Approximately 3,400 ambulance personnel from all 18 Health Trusts in Norway were invited to participate between Oct 2021 and Nov 2022. Descriptive analyses were used to describe the sample and the prevalence of findings, while multiple linear regressions were used to investigate associations. RESULTS: Altogether, 681 (20%) ambulance personnel completed the survey where 488 (72.4%) stated that they had used coercion during the last six months and 375 (55.7%) had experienced ambulance personnel or escorting personnel working with unfastened seatbelts during transport. The majority of respondents experienced coercion as being unpleasant and more negative feelings were associated with less use of seatbelts. CONCLUSIONS: Coercion seems to be used by ambulance personnel frequently. For the study participants, keeping the patient securely fastened was prioritized above escorting personnel's traffic safety, despite feeling uncomfortable doing so. Because coercive measures have negative consequences for patients, is associated with negative feelings for health personnel, and is not discussed ethically and legally in relation to the prehospital context, there is an urgent need for more research on the topic, and for legal preparatory work to address the unique perspectives of the prehospital context in which traffic safety also is an important factor.

Recent Paramedic Graduates' Chronic Stress Adds Intentions to Leave the Profession: A Pilot Study Utilizing a Web-Based Survey.

Paramedics have mentally and physically demanding jobs, and chronic stress is not uncommon. Recently graduated paramedics, in particular, have been identified as needing support in their early careers. This pilot study examined chronic stress experienced by recent graduate paramedics and their intentions to leave the paramedic profession. Finnish paramedics encompass qualifications to work in various nursing sectors. This pilot study was a cross-sectional survey study among Finnish paramedics who graduated less than 3 years ago and who were currently working in prehospital EMS (n = 152). They evaluated chronic organizational and operational stressors on the Emergency Medical Services Chronic Stress Questionnaire with 20 statements. Two structured questions related to the intention to leave the paramedic profession. Three summary scales were formed. The differences in stress by the intention to leave were reported descriptively and the differences were tested with Mann-Whitney U test. The influence of potential predictors of the intention to leave prehospital EMS work or the nursing sector completely were explored with a forward stepwise logistic regression model. Those who intended to leave prehospital EMS work (25%, n = 35/152) or to leave the nursing sector completely (33%, n = 50/152) experienced higher levels of stress than those without such intentions. Stress related to organizational inequity and leadership challenges was the strongest and stress related to social, health, and personal impacts was the second strongest predictor of the intention to leave. Reducing chronic stress might be important in terms of paramedic retention. Several further study needs are addressed.

Helmet continuous positive airway pressure for patients' transport using a single oxygen cylinder: A bench study.

BACKGROUND: Continuous positive airway pressure (CPAP) is frequently used to treat patients with acute respiratory failure in out-of-hospital settings. Compared to a facemask, the helmet has many advantages for the patient but requires a minimum gas flow of 60 L/min to avoid CO2 rebreathing. The aim of the present bench study was to evaluate the performance of four Venturi devices, connected to a single oxygen cylinder, in delivering helmet-CPAP with clinically relevant gas flow, fraction of inspired oxygen (FiO2), and positive end-expiratory pressure (PEEP) values. METHODS: Three double-inlet Venturi systems (EasyVent, Ventuplus, Compact-HAR) were connected to full 5-L oxygen cylinders using a double flowmeter, and their oxygen requirements to reach different setups (flow 60-80 L/min; FiO2 0.4-0.5-0.6, PEEP 7.5-10-12.5 cmH2O) were tested. The fourth Venturi system (O2-MAX) was directly attached to the tank, and the flow and FiO2 delivered at preset FiO2 0.3 and 0.6 were recorded. The runtime of the cylinder was assessed. RESULTS: EasyVent, Ventuplus, and O2-MAX were able to deliver helmet-CPAP with clinically useful setups when connected to a single oxygen cylinder, while Compact-HAR did not. The runtime of the cylinders ranged between 28 and 60 minutes according to the preset flow and FiO2. The delivered gas flow decreased slowly and linearly with the drop in cylinder pressure until its exhaustion. CONCLUSIONS: Helmet-CPAP might be provided using portable Venturi systems connected to an oxygen cylinder, but not all of them are able to deliver it. The use of a double flowmeter allows delivery of both high flow and high FiO2 when double-inlet Venturi systems are used. Due to the flow drop observed during the cylinder consumption, a flow >60 L/min should be set when helmet-CPAP is started. Considering the flow drop phenomenon, the estimated duration of the tank runtime can be used with a margin of safety when planning patient transport.

Impact of Smart Glasses on Patient Care Time in Emergency Medical Services Ambulance.

INTRODUCTION: The smart glasses were implemented as an innovative communication tool to enhance effectiveness in the field. The traditional mode of communication for Emergency Medical Services (EMS) was radio, which had significant restrictions, primarily that they were unable to transmit any visual data. To enhance efficiency, the smart glasses were used for a more accurate assessment of the condition of patients during transportation. At this time, however, no prior study has shown significant benefits of employing smart glasses into EMS. STUDY OBJECTIVE: The primary objective of this study is to compare the duration of patient care in an ambulance between the use and non-use of smart glasses. The secondary objective is to identify the characteristics of data communication between the ambulance and the hospital. METHODS: This retrospective study utilized data gathered from closed-circuit television (CCTV) in ambulances at Srinagarind Hospital, Thailand. The data were collected over a six-month period, specifically from July through December 2021. The study included two groups: the smart glasses group and no smart glasses groups, both used during EMS operations. The primary data collected focused on the duration of patient care in the ambulance. Additionally, the type and characteristics of data transfers via smart glasses during EMS operations were also recorded. RESULTS: Out of the 256 EMS operations included in this study, 53.1% (N = 68) of the participants in the smart glasses group were male. The majority of operations were performed during the afternoon shift in both groups. The average patient care time in the smart glasses group was 10.07 minutes, while it was 5.10 minutes in the no smart glasses group (P <.001), indicating a significant difference. Visual data communication between the ambulance and the hospital via smart glasses predominantly involved vital signs (100.0%), physical examination (56.3%), and neurological examination (42.2%). The use of audio data from the hospital to the ambulance primarily included taking additional patient history (26.6%) and performing physical examinations (19.5%). CONCLUSION: The implementation of smart glasses in EMS operations resulted in an increase in patient care time in the ambulance. Furthermore, the use of smart glasses facilitated an effective channel of real-time two-way communication between the ambulance and the hospital.

Feedback for Emergency Ambulance Staff: A National Review of Current Practice Informed by Realist Evaluation Methodology.

Research suggests that feedback in Emergency Medical Services (EMS) positively affects quality of care and professional development. However, the mechanisms by which feedback achieves its effects still need to be better understood across healthcare settings. This study aimed to understand how United Kingdom (UK) ambulance services provide feedback for EMS professionals and develop a programme theory of how feedback works within EMS, using a mixed-methods, realist evaluation framework. A national cross-sectional survey was conducted to identify feedback initiatives in UK ambulance services, followed by four in-depth case studies involving qualitative interviews and documentary analysis. We used qualitative content analysis and descriptive statistics to analyse survey responses from 40 prehospital feedback initiatives, alongside retroductive analysis of 17 interviews and six documents from case study sites. Feedback initiatives mainly provided individual patient outcome feedback through "pull" initiatives triggered by staff requests. Challenges related to information governance were identified. Our programme theory of feedback to EMS professionals encompassed context (healthcare professional and organisational characteristics), mechanisms (feedback and implementation characteristics, psychological reasoning) and outcomes (implementation, staff and service outcomes). This study suggests that most UK ambulance services use a range of feedback initiatives and provides 24 empirically based testable hypotheses for future research.
