Barriers and Enablers in Prehospital Pediatric Analgesia

ABSTRACT OBJECTIVES Children make up 5-10% of emergency medical services (EMS) transports and are at risk for under-recognition and under-treatment of pain. Prior studies have identified enablers to pediatric analgesia including EMS pediatric analgesia education, agency leadership support, the availability of assistive guides and having positive relationships with online medical control. Prior barriers identified were intravenous (IV) line insertion pain, caregiver concerns, difficulty assessing pain, pain medication safety concerns, unfamiliarity with pediatrics, unwanted attention from authority figures and perceived superiority of hospital care. This study’s objective was to evaluate enablers and barriers to prehospital analgesia for children presenting with traumatic pain after the introduction of intranasal (IN) fentanyl into EMS protocols. METHODS Focus groups with EMS clinicians were used to elicit perspectives on pediatric analgesia. EMS clinicians discussed transports of children in pain, decision-making regarding analgesic administration, available resources to treat pain including EMS protocols, patient and family reactions, and ways to improve pediatric oligoanalgesia. Themes were explored until thematic saturation was reached using a deductive approach with open-ended yet structured questions. RESULTS Enablers for pediatric analgesia included longer transports, desire to stabilize the patient, vital signs or injuries suggestive of severe pain, and clinician comfort with and availability of IN pain medication. Barriers to analgesia included concerns that the child was not stable enough for pain medication, avoiding masking symptoms prior to hospital arrival, lack of pediatric experience, lack of access to opiates in some ambulances, poor suspension in ambulances causing difficulty with IV access, patient refusal for an IV, caregivers’ discomfort with opiates and caregivers’ lack of knowledge of available prehospital medications. Focus group themes identified were that there was a lack of experience with pediatric patients, medical control was a helpful resource and training that approximated real-world situations was important. CONCLUSIONS New enablers for pediatric analgesia identified were longer transports and EMS clinician comfort with IN pain medications. While many barriers to pediatric analgesia persist, new barriers identified were poor suspension in ambulances causing difficulty with IV access and caregivers’ lack of knowledge of available prehospital medications. Additional EMS pediatric training and experience may improve pediatric oligoanalgesia.

Prehospital Restraint Use in Pediatric Patients With Mental and Behavioral Health Emergencies.

The aims of the study are to characterize children with mental and behavioral health conditions (MBH) transported by emergency medical services (EMS) and examine differences in patient, emergency department (ED), and EMS transport characteristics based on restraint interventions during EMS transport. This is a retrospective cohort study of EMS patients with MBH crises, aged 5-18, transported to 2 pediatric EDs over 9 years. Demographic and ED data were collected electronically; EMS data were extracted manually from prehospital care records. Field interventions studied included pharmacologic and mechanical restraints by EMS clinicians. Univariate analysis compared variables between patients who received EMS restraints and those who did not and multivariable logistic regression identified patient factors independently associated with EMS restraint use. Among 10,264 patients transported by EMS for MBH crises, 1400 encounters were randomly selected, with 768 records available. EMS restraint interventions were used in 73 (9.5%) patients: 5 (0.7%) received only pharmacologic restraints, 58 (7.6%) received only physical restraints, and 10 (1.3%) received both. Those who received EMS restraints were more likely to be younger (35.6% vs 19.6%, P = 0.001), male (71.2% vs 44.6%, P < 0.0001), and had longer scene times (13 vs 9 min). Restraint use was more common when patients were picked up from schools (30.1% vs 14.8%, P = 0.007). EMS-restrained patients were also more likely to receive physical (12.3% vs 2.3%, P < 0.0001), mechanical (15.1% vs 1.0%, P < 0.0001), or pharmacologic (24.7% vs 3.9%, P < 0.0001) restraints in the ED. Predictors of EMS restraint use were male sex (odds ratio, 3.00; 95% confidence interval, 1.74-5.17) and being picked up from schools (odds ratio, 2.08; 95% confidence interval, 1.13-3.81), whereas age group, race, and insurance type were not independent predictors. Nearly 1 in 10 pediatric patients experiencing mental health crises and transported by EMS required restraint interventions in the field. Male patients, younger aged children, and those picked up from school represent a distinct and vulnerable population that could benefit from specialized prehospital care to manage agitation.

Emergency Medical Services and Police Utilization for Pediatric Mental and Behavioral Health Concerns Within a Large Hospital System.

This study aimed to compare emergency medical services (EMS) and police utilization trends, epidemiology, and emergency department (ED) outcomes between pediatric patients with mental or behavioral health (MBH) emergencies and those with non-MBH concerns transported to a large children's hospital system. This was a retrospective cohort study of patients aged 5 to 18 years transported via EMS and police to two EDs affiliated with a children's hospital from January 2012 through December 2020. Data were abstracted from electronic hospital records. Encounters for MBH emergencies were identified using diagnostic codes and chief complaints. Trends of EMS and police transports of patients with MBH emergencies were examined. Patient demographics and ED outcomes were compared between children presenting with MBH emergencies and those with non-MBH concerns. During the 9-year study period, out of 40,663 transports to the EDs, 36,137 (89%) arrived via EMS, and 4,526 (11%) arrived via police. A total of 10,250 (28.4%) EMS transports were for MBH emergencies. The volume of patients transported by EMS for MBH emergencies increased by 1.4% per year (P < 0.01) with no significant change in total EMS patient volumes. Patients with MBH emergencies transported by EMS were more likely to be older, female, of White race, and publicly insured; require restraint in the ED; and be admitted (P < 0.001). Of police transports, 4153 (91.8%) were for MBH emergencies, with no statistical change in the proportion of police transports that were for MBH emergencies. Police-transported MBH patients compared to non-MBH police-transported patients were more likely to be younger, female, and of White race (P < 0.001); 8.7% required mechanical/physical restraints in ED, 6.7% required pharmacologic restraint medications in ED, and 53% were admitted. The proportion of pediatric transports for MBH emergencies by EMS is rising and comprises the majority of police transports. Distinct from non-MBH pediatric patients transported, MBH patients necessitate significant ED resources, including ED-administered restraints and admission, highlighting their unique burden on the prehospital and ED systems.

The rate and predictors of violence against EMS personnel

BackgroundViolence against Emergency Medical Services (EMS) personnel vary between studies. Current studies are mainly based on self-reporting, thus other designs are needed to provide more perspective. The purpose of this study was to explore the rate and predictors of violent behavior targeted at EMS personnel by exploring the Electronic patient care records (ePCR) documentation by EMS personnel.MethodsThis was a retrospective cohort study of EMS patients in Finland. The data were collected from three regions between 1st June and 30th November 2018. Text mining and manual evaluation were used to identify and explore predictors of violence targeted at EMS personnel from the ePCR narratives. Multivariable logistic regressions were used to determine factors that were independently associated with violent behavior. The results are presented with odds ratios (ORs) with 95% confidence intervals (CIs).ResultsThe EMS personnel reported experiences of violence in a total of 297 identified missions (0.7%) of all EMS missions (n = 40,263). The violence was mostly verbal (62.3%) and the most common violence perpetrator was the patient (98.0%). The police were alarmed to many missions where violence was reported (40.7%). Sometimes violence occurred suddenly although the police were present. The multivariable logistic regression model indicates that violence occurred typically in urban areas (OR 1.699; 95% CI 1.283 to 2.248), at weekend nights (OR 1.357; 95% CI 1.043 to 1.765), by male (OR 1.501; 95% CI 1.160 to 1.942), and patients influenced by alcohol (OR 3.464; 95% CI 2.644 to 4.538). A NEWS2 score of 3 in any parameter (vs. score 0–4, OR 2.386; 95% CI: 1.788 to 3.185) and ALS unit type (vs. BLS, OR 1.373; 95% CI: 1.009 to 1.866) increased the likelihood as well.ConclusionsThe documentation in ePCRs show low rates of violence targeted at EMS personnel. However, violence is a multidimensional phenomenon connected to unfamiliar patients, rushed situations, and an uncontrolled environment. This means that the EMS personnels’ safety cannot be ensured in all situations. Therefore, a balance between safety margins and treating patients needs to be considered.

Layperson-Administered Naloxone Trends Reported in Emergency Medical Service Activations, 2020-2022

Layperson-administered naloxone (LAN) is a powerful but incompletely characterized intervention to prevent opioid-related overdose mortality. LAN trends are relevant to policy and strategic planning in naloxone distribution initiatives. To assess the 2-year LAN trend for persons in the United States receiving naloxone during emergency medical services (EMS) activations. This retrospective cross-sectional study was conducted in the United States from June 2020 to June 2022 among 65 621 195 EMS activations from 911 responses, EMS standbys, or when EMS crews functioned in an ambulance intercept role or during mutual aid to another ambulance response. Activations within health care settings and interfacility or medical transports were excluded. Data are from the National Emergency Medical Services Information System (NEMSIS), the national EMS patient care record database. From June 2020 to June 2022, NEMSIS included more than 96 million EMS activations from nearly 14 000 agencies across 54 states and territories. EMS clinician-reported LAN. The primary outcome was the trend of receiving LAN, measured by EMS clinician documentation. From June 2020 to June 2022, EMS reported 744 078 patients receiving naloxone, with 24 990 (3.4%) involving LAN. Patients were predominantly male (17 331 [69.4%]) and had a median (IQR) age of 42 (31-56) years, with the majority treated in urban homes or residences (21 692 [86.8%] urban; 13 223 [52.9%] in-home or residence). Of the total naloxone recipients, 243 985 patients (32.8%) had suspected drug overdose documentation as either the primary or secondary impression. Overall, the percentage change in naloxone administration rates decreased 6.1% over the study period (from 1140.1 [95% CI, 1135.1-1145.1] per 100 000 EMS activations to 1070.1 [95% CI, 1064.9-1075.3] per 100 000 EMS activations), while the percentage change of persons receiving LAN increased 43.5% (from 30.0 [95% CI, 29.2-30.8] per 100 000 EMS activations to 43.1 [95% CI, 42.0-44.1] per 100 000 EMS activations). In this cross-sectional study, the LAN rate increased from June 2020 to June 2022 as reported in the national EMS database. These findings help inform policies and practices aimed at mitigating the devastating impacts of the opioid epidemic and saving lives. Novel public health strategies are needed to measure the effects of this intervention nationally, evaluate approaches to expand naloxone distribution, and address naloxone usage barriers.

Evaluation of Isopropyl Alcohol Aromatherapy in Treating Nausea in Helicopter Emergency Medical Services Patients

ObjectiveIsopropyl alcohol (IPA) aromatherapy provides rapid relief of nausea at minimal cost, is universally available, and has no known significant adverse effects. These attributes make it ideal for the prehospital setting. However, there is no published research on the use of IPA in critical care transport (CCT). The objective of this study was to investigate if CCT patients experience improvement of nausea with IPA aromatherapy. MethodsA retrospective chart review was performed over a 2-year period on adult patients served by a Midwest CCT system that provides both air and ground transport. Data were obtained 1 year before and 1 year after a protocol change in which the first-line antiemetic was changed from intravenous ondansetron (prechange) to inhaled IPA (postchange). The IPA was administered by placing a pad under the patient's nares as they inhaled. The proportion of nausea improvement was compared between the prechange and postchange periods. ResultsTwo hundred seventeen records were included. In helicopter emergency medical services, 33 of 50 (66.0%) patients reported improvement with ondansetron, and 13 of 21 (61.9%) reported improvement with IPA (P = .742). Patients transported by ground emergency medical services showed improvement in 65 of 73 (89.0%) cases for ondansetron and 40 of 73 (54.8%) for IPA (P < .001). ConclusionThere was no difference in the proportion of nausea improvement between ondansetron and IPA in helicopter emergency medical services patients. In ground emergency medical services patients, more patients had nausea improvement with ondansetron compared with IPA. This study suggests IPA may be a faster, more efficacious alternative for nausea relief in CCT patients.

Influence of patient body weight on the probability of return of spontaneous circulation following out-of-hospital cardiac arrest: an exploratory analysis.

In addition to key interventions, including bystander CPR and defibrillation, successful resuscitation of out-of-hospital cardiac arrest (OHCA) is also associated with several patient-level factors, including a shockable presenting rhythm, younger age, Caucasian race and female sex. An additional patient-level factor that may influence outcomes is patient weight, yet this attribute has not been extensively studied within the context of OHCA, despite globally increasing obesity rates. To assess the relationship between patient weight and return of spontaneous circulation (ROSC) during OHCA. This retrospective study included adult patients from a national emergency medical services (EMS) patient record, with witnessed, non-traumatic OHCA prior to EMS arrival from January to December 2020. Logistic regression was used to evaluate the relationship between patient weight and ROSC. Complete records were available for 9096 patients, of which 64.3% were males and 25.3% were ethnic minorities. The mean age of the participants was 65.01 years (SD = 15.8), with a mean weight of 93.52 kg (SD = 31.5). Altogether, 81.8% of arrests were of presumed cardiac aetiology and 30.3% presented with a shockable rhythm. Bystander CPR and automated external defibrillator (AED) shock were performed in 30.6% and 7.3% of cases, respectively, and 44.0% experienced ROSC. ROSC was less likely with patient weight >100 kg (OR = 0.709, p <0.001), male sex (OR = 0.782, p <0.001), and increasing age and EMS response time (OR = 0.994 per year, p <0.001 and OR = 0.970 per minute, p <0.001, respectively). Patients with shockable rhythms were more likely to achieve ROSC (OR = 1.790, p <0.001), as were patients receiving bystander CPR (OR = 1.170, p <0.001) and defibrillation prior to EMS arrival (OR = 1.658, p <0.001). Although the mean first adrenaline dose (mg/kg) followed a downward trend due to its non-weight-based dosing scheme, the mean total adrenaline dose administered to achieve ROSC demonstrated an upward linear trend of 0.05 mg for every 5 kg of body weight. Patient weight was negatively associated with ROSC and positively associated with the total adrenaline dose required to attain ROSC.

The Epidemiology of Out-of-Hospital Pediatric Airway Management in the 2019 ESO Data Collaborative

Objectives Airway management is a fundamental skill that Emergency Medical Services (EMS) clinicians must be prepared to perform on patients of any age. We performed one of the first epidemiological studies of out-of-hospital pediatric airway management utilizing the ESO data set. Methods We used the 2019 ESO Data Collaborative public release research data set. We performed a descriptive analysis of all patients <18 years receiving at least one of the following airway management interventions: nasopharyngeal airway, oropharyngeal airway, noninvasive positive pressure ventilation (NIPPV), airway suctioning, bag-valve-mask ventilation (BVM), tracheal intubation (TI), supraglottic airway (SGA) or surgical airway placement. We determined the success rates for BVM, TI and SGA. Results Among 7,422,710 911 EMS activations, there were 346,912 pediatric encounters that resulted in patient care. Airway management occurred in 27,071 encounters (7,803 per 100,000 pediatric EMS patient care events). Use of BVM, intubation or supraglottic airway insertion occurred in 3,496 encounters (1,007 per 100,000 pediatric EMS patient care events). Ventilation with BVM occurred in 2,226 encounters (642 per 100,000 pediatric EMS patient care events), TI in 935 pediatric EMS patient care encounters (270 per 100,000 patient care encounters), and supraglottic airway insertion in 335 patient encounters (97 per 100,000 patient care encounters). Overall TI success was 71.4%, rapid sequence intubation success was 86.3%, and SGA success was 87.2%. Overall TI first pass success rate was 63.1%. Conclusions In the ESO cohort, advanced airway management of children occurred in only 5.9 in 10,000 911 emergency encounters. Overall and first pass success rates for TI were low. These data provide contemporary perspectives of pediatric prehospital airway management in the United States.

Outcomes of adult patients discharged at scene by emergency medical services

BackgroundThe outcomes of patients who call an ambulance but are discharged at scene reflect the safety and quality of emergency medical service (EMS) care. While previous studies have examined the...

Statistical machine learning models for prediction of China's maritime emergency patients in dynamic: ARIMA model, SARIMA model, and dynamic Bayesian network model.

Rescuing individuals at sea is a pressing global public health issue, garnering substantial attention from emergency medicine researchers with a focus on improving prevention and control strategies. This study aims to develop a Dynamic Bayesian Networks (DBN) model utilizing maritime emergency incident data and compare its forecasting accuracy to Auto-regressive Integrated Moving Average (ARIMA) and Seasonal Auto-regressive Integrated Moving Average (SARIMA) models. In this research, we analyzed the count of cases managed by five hospitals in Hainan Province from January 2016 to December 2020 in the context of maritime emergency care. We employed diverse approaches to construct and calibrate ARIMA, SARIMA, and DBN models. These models were subsequently utilized to forecast the number of emergency responders from January 2021 to December 2021. The study indicated that the ARIMA, SARIMA, and DBN models effectively modeled and forecasted Maritime Emergency Medical Service (EMS) patient data, accounting for seasonal variations. The predictive accuracy was evaluated using Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and Coefficient of Determination (R 2) as performance metrics. In this study, the ARIMA, SARIMA, and DBN models reported RMSE of 5.75, 4.43, and 5.45; MAE of 4.13, 2.81, and 3.85; and R 2 values of 0.21, 0.54, and 0.44, respectively. MAE and RMSE assess the level of difference between the actual and predicted values. A smaller value indicates a more accurate model prediction. R 2 can compare the performance of models across different aspects, with a range of values from 0 to 1. A value closer to 1 signifies better model quality. As errors increase, R 2 moves further from the maximum value. The SARIMA model outperformed the others, demonstrating the lowest RMSE and MAE, alongside the highest R 2, during both modeling and forecasting. Analysis of predicted values and fitting plots reveals that, in most instances, SARIMA's predictions closely align with the actual number of rescues. Thus, SARIMA is superior in both fitting and forecasting, followed by the DBN model, with ARIMA showing the least accurate predictions. While the DBN model adeptly captures variable correlations, the SARIMA model excels in forecasting maritime emergency cases. By comparing these models, we glean valuable insights into maritime emergency trends, facilitating the development of effective prevention and control strategies.

Benefits, barriers and facilitators for out-of-hospital point of care testing: a qualitative study

Background Heightened pressures on hospitals and Emergency Medical Services (EMS) due to growing demand and staff shortages have led to prolonged ambulance response times and delays in handing over the care of EMS patients on arrival at an Emergency Department. These delays jeopardise patient safety and staff wellbeing. Point of care (POC) tests in EMS have been proposed to facilitate effective on-scene decision-making, reduced conveyance, improved clinical outcomes, enhanced system efficiency and patient experience. Despite an acceleration in POC testing during the Covid-19 pandemic, limited evidence exists for integrating POC tests into routine EMS practice. The aim of this research was to explore the impact, benefits, barriers, and facilitators of POC testing in United Kingdom (UK) EMS, alongside factors influencing future research on POC testing implementation. Methods Convenience and snowballing sample techniques were used to recruit a diverse stakeholder group, including patient and public participants, for online semi-structured interviews between June and July 2023. Interviews were recorded, transcribed verbatim and thematically analysed using the framework method. The codes were pre-selected using the outcomes of a prior stakeholder event and double coded by the research team. Results A total of 25 participants took part in semi-structured interviews. Whilst most participants identified clear potential benefits associated with the implementation of further POC tests within UK EMS, barriers that need to be considered in future research were also highlighted. Three themes were identified: enhancing patient care and system efficiency through POC testing; navigating implementation challenges: balancing barriers and facilitators for successful implementation; building the foundations: key considerations for future research. Conclusions Our study indicates that although the adoption of further POC testing was viewed positively, with substantial potential for impact, it will be essential to carefully address the barriers identified, along with insights from prior research, to overcome the associated challenges effectively.

Do differences in emergency medical services (EMS) response time to an arrest account for the survival differences between EMS-witnessed and bystander-witnessed out of hospital cardiac arrest?

IntroductionOut-of-hospital cardiac arrests (OHCA) witnessed by Emergency Medical Services (EMS) are reported to have more favourable survival than bystander-witnessed arrests, even after adjusting for patient and arrest factors known to be associated with increased OHCA survival. This study aims to determine whether the survival advantage in EMS-witnessed arrests can be attributed to differences in the EMS response time to the arrest. MethodsUsing registry data we conducted a retrospective, population-based cohort study of bystander- and EMS-witnessed OHCAs of medical aetiology who received an EMS resuscitation attempt in Western Australia between 2018–2021. EMS response time to arrest was assumed to be zero for EMS-witnessed arrests. Multivariable logistic regression was used to compare 30-day OHCA survival by witness and bystander CPR (B-CPR) status, adjusting for EMS response time to arrest, and patient and arrest characteristics. ResultsOf 2,130 OHCA cases, 510 (23.9%) were EMS-witnessed and 1620 were bystander-witnessed: 1318/1620 (81.4%) with B-CPR, and 302/1620 (18.6%) with no B-CPR. The median EMS response time to bystander-witnessed arrests who received B-CPR was 9.9 [Q1,Q3: 7.4, 13.3] minutes. After adjusting for the EMS response time and patient and arrest factors, 30-day survival remained significantly lower in both the bystander-witnessed group with B-CPR (aOR 0.56; 95% CI 0.34 – 0.91) and bystander-witnessed group without B-CPR (aOR 0.23; 95% CI 0.11 – 0.46). ConclusionAn increased EMS response time does not fully account for the higher OHCA survival in EMS-witnessed arrests compared to bystander-witnessed arrests.

Post-ROSC Atrial fibrillation is not associated with rearrest but is associated with stroke and mortality following out of hospital cardiac arrest

BackgroundAtrial fibrillation (AF) in patients resuscitated from cardiac arrest (CA) is associated with increased short-term mortality. However, whether this is because AF adversely affects early resuscitation success, causes post-resuscitation morbidity, or because it is a marker for patient co-morbidities, remains unclear. We aimed to determine the prevalence of AF in patients with ROSC to test the hypothesis that AF is associated with increased risk of rearrest and to determine its impact on mortality and stroke risk. MethodsWe performed a retrospective study of emergency medical services patients with OHCA and ROSC. To examine long-term morbidity and mortality due to AF, an additional observational cohort analysis was performed using a large electronic health record (EHR) database. ResultsOne hundred nineteen patients with ROSC prior to ED arrival were identified. AF was observed in 39 (33%) of patients. Rearrest was not different between AF and no AF groups (44% vs. 41%, p = 0.94). In the EHR analysis, mortality at one year in patients who developed AF was 59% vs. 39% in no AF patients. Odds of stroke was 5x greater in AF patients (p < 0.001), with the majority not anticoagulated (93%, p < 0.001) and comorbidities were greater p < 0.001). ConclusionsAF was common following ROSC and not associated with rearrest. AF after CA was associated with increased mortality and stroke risk. These data suggest rhythm control for AF in the immediate post-ROSC period is not warranted; however, vigilance is required for patients who develop persistent AF, particularly with regards to stroke risk and prevention.

Ambulance service recognition of health inequalities and activities for reduction: An evidence and gap map of the published literature.

Emergency medical services (EMS) are often patients' first point of contact for urgent and emergency care needs. Patients are triaged over the phone and may receive an ambulance response, with potential conveyance to the hospital. A recent scoping review suggested disparities in EMS patient care in the United States. However, it is unknown how health inequalities impact EMS care in other developed countries and how inequalities are being addressed. This rapid evidence map of published literature aims to map known health inequalities in EMS patients and describe interventions reducing health inequalities in EMS patient care. The search strategy consisted of EMS synonyms and health inequality synonyms. The MEDLINE/PubMed database was searched from 1 January 2010 to 26 July 2022. Studies were included if they described empirical research exploring health inequalities within ambulance service patient care. Studies were mapped on to the EMS care interventions framework and Core20PLUS5 framework. Studies evaluating interventions were synthesised using the United Kingdom Allied Health Professions Public Health Strategic Framework. The search strategy yielded 771 articles, excluding duplicates, with two more studies added from hand searches. One hundred studies met the inclusion criteria after full-text review. Inequalities in EMS patient care were predominantly situated in assessment, treatment and conveyance, although triage and response performance were also represented. Studies mostly explored EMS health inequalities within ethnic minority populations, populations with protected characteristics and the core issue of social deprivation. Studies evaluating interventions reducing health inequalities (n = 5) were from outside the United Kingdom and focused on older patients, ethnic minorities and those with limited English proficiency. Interventions included community paramedics, awareness campaigns, dedicated language lines and changes to EMS protocols. Further UK-based research exploring health inequalities of EMS patients would support ambulance service policy and intervention development to reduce health inequality in urgent and emergency care delivery.

Achieving Equity in EMS Care and Patient Outcomes Through Quality Management Systems: A Position Statement

Improving health and safety in our communities requires deliberate focus and commitment to equity. Inequities are differences in access, treatment, and outcomes between individuals and across populations that are systemic, avoidable, and unjust. Within health care in general, and Emergency Medical Services (EMS) in particular, there are demonstrated inequities in the quality of care provided to patients based on a number of characteristics linked to discrimination, exclusion, or bias. Given the critical role that EMS plays within the health care system, it is imperative that EMS systems reduce inequities by delivering evidence-based, high-quality care for the communities and patients we serve. To achieve equity in EMS care delivery and patient outcomes, the National Association of EMS Physicians recommends that EMS systems and agencies: make health equity a strategic priority and commit to improving equity at all levels. assess and monitor clinical and safety quality measures through the lens of inequities as an integrated part of the quality management process. ensure that data elements are structured to enable equity analysis at every level and routinely evaluate data for limitations hindering equity analysis and improvement. involve patients and community stakeholders in determining data ownership and stewardship to ensure its ongoing evolution and fitness for use for measuring care inequities. address biases as they translate into the quality of care and standards of respect for patients. pursue equity through a framework rooted in the principles of improvement science.

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

BackgroundEmergency 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?MethodsThis 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.ResultsNon-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.ConclusionsPatients 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.

Building a unified communications centre to improve the distribution of EMS patients to a large multi-hospital health system

In 2023, hospital care-based models are faced with increasing patient volumes, limited physical space and limited resources. These constraints, felt in almost all acute-based care models, is leading to a crucial crossroads in acute care delivery. Balancing capacity and availability of hospital and system resources is almost impossible in this environment, as need greatly exceeds access to resources and patient care delivery can be significantly hindered. Historically, emergency medical services (EMS) brought patients to the nearest available emergency department (ED), and load balancing could only be accomplished after arrival in the ED. Intervening earlier in patient’s care by providing EMS with destination recommendations based on available resources optimises patient outcomes and decreases the burden on any individual hospital. This change can also greatly affect EMS processes to improve transport times and decrease wall time, the time that EMS crews spend at the hospital waiting to offload their patients into a hospital bed. Wall times can exceed several hours depending on location, time of day and patient resource needs. Reduction of this waiting time has the potential to profoundly improve throughput and patient-centred metrics like patient satisfaction, length of stay and admission rates, as well as reduce overall risk. This also allows health systems to maintain community resources by decreasing EMS crews’ idle time at the hospital. Through the creation of a unified communication centre (UCC), we sought to create a structure that appropriately stratified patients to the most appropriate system hospitals while still in the care of EMS. Our team’s goal was to optimise patient treatment, decrease wall time with EMS, and route patients to the most appropriate facility based on the patient’s medical complaints, hospital capacity and hospital capability in the community.

Abstract WMP78: Mobile Stroke Units Enable Hyperacute Interventions for Intracerebral Hemorrhage

Introduction: Mobile stroke units (MSUs) are an evolving means to expedited acute stroke management. Recent landmark trials BEST-MSU and B_PROUD have proven that MSUs facilitate quicker thrombolysis times and improved functional outcomes at 90 days when compared to conventional emergency medical services (EMS) for acute ischemic stroke patients. Despite the growing body of literature surrounding MSUs and acute ischemic stroke, literature describing the intracerebral hemorrhage experience in MSUs has been lacking. Methods: Retrospective analysis of consecutive patients with acute intracerebral hemorrhage triaged by MSU or EMS from January 2018 to December 2022 was performed at two tertiary institutions. In the EMS cohort, only patients seen between 8 am to 8 pm, corresponding to the operating hours of the MSU, were included. Goal blood pressure was defined as systolic blood pressure &lt;160. Chi-squared test for categorical variables and t-test for continuous variables were used for statistical analysis. Results: A total of 146 MSU patients were compared to 221 EMS patients. Both cohorts had similar baseline demographics. Median initial blood pressure in the MSU was 190/99, which dropped to a median blood pressure of 157/80 upon arrival to the hospital. Initial systolic blood pressure in the hospital was significantly higher for EMS compared to MSU patients (166 vs 157, p=0.011). The majority (77%) of MSU patients received anti-hypertensive medications while in the MSU. Times from door to CT completion (14 vs 33 min, p=0.000), anticoagulation reversal (99 vs 139 min, p=0.013), anti-hypertensive medication administration (21 vs 45 min, p=0.020), and goal blood pressure (35 vs 51 min, p=0.000) were significantly faster in the MSU cohort. Conclusions: MSUs provide faster medical treatment for patients with acute intracerebral hemorrhage. The target blood pressure goal was met much quicker in the MSU. Faster time metrics convey a hypothetical benefit towards improved patient outcomes.

Comparative epidemiology and outcomes among trauma patients transported by private and formal pre-hospital care modes in Kigali, Rwanda

INTRODUCTION: The burden of injuries is high in low- and middle-income countries where pre-hospital systems are being developed to improve acute injury care. This study compares the characteristics and outcomes between trauma patients transported by formal emergency medical services (EMS) and by private transport to the emergency department (ED) of the Centre Hospitalier Universitaire de Kigali (CHUK) in Rwanda.&#x0D; METHODS: This retrospective cohort study analyzed a random sample of trauma patients presenting between 1 August 2015 and 30 July 2016. Descriptive analyses were performed, and differences in outcomes were assessed based on transport modalities via Pearson Chi-Squared or Fisher’s Exact tests.&#x0D; RESULTS: Of the 556 trauma patients analyzed, 87.1% were transported by private transport and the remainder by EMS. The median inpatient length of stay for private transport patients was 7 days (IQR:3-16 days), compared to 9.5 days for EMS patients (IQR:4-18 days) (p=0.301). More EMS-transported patients died in the ED (p=0.005), and more were admitted to the hospital. There was a higher mortality rate among patients admitted to the hospital who arrived by private transport, but the difference was not statistically significant.&#x0D; CONCLUSION: The higher ED death rate among EMS-transported patients and the higher in-hospital death rate among private transport patients suggest that major differences in the two groups may or may not be related to how trauma patients are brought to the ED.

Description of the Public Safety Medical Response and Patient Encounters Within and During the Indianapolis (USA) Spring 2020 Civil Unrest.

This study describes the local Emergency Medical Services (EMS) response and patient encounters corresponding to the civil unrest occurring over a four-day period in Spring 2020 in Indianapolis, Indiana (USA). This study describes the non-conventional EMS response to civil unrest. The study included patients encountered by EMS in the area of the civil unrest occurring in Indianapolis, Indiana from May 29 through June 1, 2020. The area of civil unrest defined by Indianapolis Metropolitan Police Department covered 15 blocks by 12 blocks (roughly 4.0 square miles) and included central Indianapolis. The study analyzed records and collected demographics, scene times, interventions, dispositions, EMS clinician narratives, transport destinations, and hospital course with outcomes from receiving hospitals for patients extracted from the area of civil unrest by EMS. Twenty-nine patients were included with ages ranging from two to sixty-eight years. In total, EMS transported 72.4% (21 of 29) of the patients, with the remainder declining transport. Ballistic injuries from gun violence accounted for 10.3% (3 of 29) of injuries. Two additional fatalities from penetrating trauma occurred among patients without EMS contact within and during the civil unrest. Conditions not involving trauma occurred in 37.9% (11 of 29). Among transported patients, 33.3% (7 of 21) were admitted to the hospital and there was one fatality. While most EMS transports did not result in hospitalization, it is important to note that the majority of EMS calls did result in a transport. There was a substantial amount of non-traumatic patient encounters. Trauma in many of the encounters was relatively severe, and the findings imply the need for rapid extraction methods from dangerous areas to facilitate timely in-hospital stabilization.
