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

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

Pediatric trauma patients in Swedish ambulance services -a retrospective observational study of assessments, interventions, and clinical outcomes.

BACKGROUND: Pediatric trauma patients constitute a significant portion of the trauma population treated by Swedish Emergency Medical Services (EMS), and trauma remains a notable cause of death among Swedish children. Previous research has identified potential challenges in prehospital assessments and interventions for pediatric patients. In Sweden, there is limited information available regarding pediatric trauma patients in the EMS. The aim of this study was to investigate the prevalence of pediatric trauma patients within the Swedish EMS and describe the prehospital assessments, interventions, and clinical outcomes. METHODS: This retrospective observational study was conducted in a region of Southwestern Sweden. A random sample from ambulance and hospital records from the year 2019 was selected. Inclusion criteria were children aged 0-16 years who were involved in trauma and assessed by EMS clinicians. RESULTS: A total of 440 children were included in the study, representing 8.4% of the overall trauma cases. The median age was 9 years (IQR 3-12), and 60.5% were male. The leading causes of injury were low (34.8%) and high energy falls (21%), followed by traffic accidents. The children were assessed as severely injured in 4.5% of cases. A quarter of the children remained at the scene after assessment. Complete vital signs were assessed in 29.3% of children, and 81.8% of children were assessed according to the ABCDE structure. The most common intervention performed by prehospital professionals was the administration of medication. The mortality rate was 0.2%. CONCLUSIONS: Pediatric trauma cases accounted for 8.4% of the overall trauma population with a variations in injury mechanisms and types. Vital sign assessments were incomplete for a significant proportion of children. The adherence to the ABCDE structure, however, was higher. The children remained at the scene after assessment requires further investigation for patient safety.

Innovative techniques in the treatment of penile strangulation: a case report.

Introduction and importance: Penile strangulation is a medical emergency characterized by the encirclement of the penis by an external object, resulting in circulatory compromise. Case presentation: A 35-year-old male presented with penile pain and urinary obstruction due to the inability to remove the ring. Upon examination, the ring was firmly lodged at the base of the penis, causing significant swelling and discoloration in the distal region. Interventions and outcomes: Initial attempts to cut the ring using standard tools were unsuccessful, leading to the engagement of a rescue team equipped with an air cutter. The cutting procedure, complicated by the ring's thickness and hardness and the significant edema, took ~90 min. Safety measures, including the use of a surgical brain spatula and forceps, were employed to protect the penile skin from damage during the operation. Relevance and impact: This case underscores the necessity for timely intervention in penile strangulation cases and highlights the effectiveness of collaboration with specialized rescue teams equipped with appropriate cutting tools. It also emphasizes the importance of safety considerations when employing nonmedical devices in medical emergencies. The patient experienced a favorable outcome, with significant improvement in swelling and discoloration postprocedure, and no complications during follow-up. This report contributes to the limited but crucial literature on managing penile strangulation, particularly regarding the methods and timeframes for safely removing constricting objects.

Assessing Fall Mortality by Field-Relevant Categories at an Urban Level I Trauma Center.

INTRODUCTION: Little research has focused on assessing the mortality for fall height based on field-relevant categories like falls from greater than standing (FFGS), falls from standing (FFS), and falls from less than standing. METHODS: This retrospective observational study included patients evaluated for a fall incident at an urban Level I Trauma Center or included in Medical Examiner's log from January 1, 2015, to June 31, 2017. Descriptive statistics characterized the sample based on demographic variables such as age, race, sex, and insurance type, as well as injury characteristics like relative fall height, Glasgow Coma Scale (GCS), Injury Severity Score (ISS), traumatic brain injury, intensive care unit length of stay, and mortality. Bivariate analysis included Chi-square tests for categorical variables and Student t-tests for continuous variables. Subsequent multiple logistic regression modeled significant variables from bivariate analyses, including age, race, insurance status, fall height, ISS, and GCS. RESULTS: When adjusting for sex, age, race, insurance, ISS, and GCS, adults ≥65 who FFS had 1.93 times the odds of mortality than those who FFGS. However, those <65 who FFGS had 3.12 times the odds of mortality than those who FFS. Additionally, commercial insurance was not protective across age groups. CONCLUSIONS: The mortality for FFS may be higher than FFGS under certain circumstances, particularly among those ≥65 y. Therefore, prehospital collection should include accurate assessment of fall height and surface (i.e., water, concrete). Lastly, commercial insurance was likely a proxy for industrial falls, accounting for the surprising lack of protection against mortality.

Emergency reflex action drill for traumatic cardiac arrest in a simulated pre-hospital setting; a one-group pre-post intervention study.

BACKGROUND: Emergency Reflex Action Drills (ERADs) are meant to decrease stress-associated cognitive demand in high urgency situations. The aim of this study was to develop and test an ERAD for witnessed traumatic cardiac arrest (TCA), an event in which potentially reversible causes need to be systematically addressed and treated in a short period of time. We hypothesize that this ERAD (the TCA-Drill) helps ground Emergency Medical Services (EMS) nurses in overcoming performance decline during this specific high-pressure situation. METHODS: This was a prospective, experimental one-group pre-post intervention study. Ground EMS nurses participated in a session of four simulated scenarios, with an in-between educational session to teach the TCA-Drill. Scenarios were video recorded, after which adherence and time differences were analyzed. Self-confidence on clinical practice was measured before and after the scenarios. RESULTS: Twelve ground EMS nurses participated in this study. Overall median time to address reversible causes of TCA decreased significantly using the TCA-Drill (132 vs. 110 s; p = 0.030) compared with the conventional ALS strategy. More specifically, participants adhering to the TCA-Drill showed a significantly lower time needed for hemorrhage control (58 vs. 37 s; p = 0.012). Eight of 12 (67 %) ground EMS nurses performed the ERAD without protocol deviations. Reported self-confidence significantly increased on 11 of the 13 surveyed items. CONCLUSIONS: The use of an ERAD for TCA (the TCA-Drill) significantly reduces the time to address reversible causes for TCA without delaying chest compressions in a simulated environment and can be easily taught to ground EMS nurses and increases self-confidence. IMPLICATIONS FOR CLINICAL PRACTICE: The use of an ERAD for TCA (the TCA-Drill can significantly reduce the time to address reversible causes for TCA without delaying chest compression. This drill can be easily taught to ground EMS nurses and increases their self-confidence in addressing TCA-patients.

Social mass gathering events influence emergency medical services call volume.

Background: Prior literature suggests that mass gathering events pose challenges to an emergency medical services (EMS) system. We aimed to investigate whether events influence EMS call rates. Materials and methods: This study is a retrospective review of all primary response ambulance calls in Rhode Island (US) between January 1st, 2018 and August 31st, 2022. The number of EMS calls per day was taken from the state's EMS registry. Event data was collected using a Google (Google LLC, Mountain View, CA) search. We used separate Poisson regression models with the number of ambulance calls as the dependent and the social event categories sports, agricultural, music events, and public exhibitions as independent variables. All models controlled for the population at risk and the period of the COVID-19 pandemic. Results are presented as increases or decreases in calls per 100,000 inhabitants from the mean over the study period. Results: The mean number of daily EMS calls was 38 ± 4 per 100,000 inhabitants. EMS encountered significantly more missions on days with music events (+3, 95% CI [2; 3]) and public exhibitions (+2, 95% CI [1; 2]). In contrast, days with agricultural events were associated with fewer calls (-1, 95% CI [-1; 0]). We did not find any effect of sports events on call rates. Conclusion: Increased ambulance call volumes are observed on days with music events and public exhibitions. Days with agricultural events are associated with fewer EMS calls.

The Road to 988/911 Interoperability: Three Case Studies on Call Transfer, Colocation, and Community Response.

The 988 Suicide and Crisis Lifeline-known more simply as 988-holds promise for significantly improving the mental health of Americans and accelerating the decriminalization of mental illness. However, the rapid transition to 988 has left many gaps as communities scramble to prepare-not the least of which includes determining how 988 will interface with local 911 response systems and law enforcement. 911 is often the default option for individuals experiencing mental health emergencies, despite the fact that 911 call centers have limited resources to address behavioral health crises. Since 988 launched in 2022, one key area of focus has been ways that jurisdictions approach 988/911 interoperability: the existence of formal protocols, procedures, or agreements that allow for the transfer of calls from 988 to 911 and vice versa. This study presents case studies from three jurisdictions that have established models of 988/911 interoperability. It provides details related to interoperability in each model, including the role of each agency, points of interagency communication, and decision points that can affect the way a call flows through the local system. It also identifies facilitators, barriers, and equity-related considerations of each jurisdiction's approach, as well as lessons learned from implementation. This study should be of interest to jurisdictions that are looking to implement 988/911 interoperability, including those that are spearheading local initiatives and those that are responding to state-level legislation. Its findings are relevant to 988 call centers, public safety answering points, mobile crisis units, law enforcement, and local and state decisionmakers.

A Qualitative Review of the Air Rescue One Rural Search and Rescue Program in British Columbia, Canada.

INTRODUCTION: Rural emergency prehospital care in British Columbia is conducted primarily by the British Columbia Ambulance Services or ground search and rescue volunteers. Since 2014, the volunteer Air Rescue One (AR1) program has provided helicopter emergency winch rescue services to rural British Columbia. The aim of this research was to describe the activity of the AR1 program and to make recommendations to improve future operations. METHODS: Data were collected retrospectively from September 2014 to May 2021, and parameters of emergency callout statistics from the organization's standard operating guidelines, rescue reports, and interviews were summarized and reviewed. RESULTS: Of 152 missions within the study period, 105 were medically related rescues involving trauma or cardiac events. Snowmobiling, mountain biking, and hiking were the most common activities requiring rescue. The 38 medical callouts that were not completed by AR1 were reviewed for contributing factors. Response time varied due to the vast service area, but median time from request to takeoff was 55 min (interquartile range 47-69 min), and median on-scene time was 21 min (interquartile range 11-33 min). CONCLUSIONS: AR1 provides advanced medical care into British Columbia's remote and difficult-to-access areas, minimizing delays in treatment and risk to patients and responders. Callout procedures should be streamlined enabling efficient AR1 activation. Collection of medical and flight information should be improved with standardized documentation, aiding in internal education and future research into the program's impact on emergency prehospital care. Future directions for improvement of care include the possibility of introducing portable ultrasound technology.

Disparity in guideline adherence for prehospital care according to patient age in emergency medical service transport for moderate to severe trauma.

OBJECTIVES: The aim of this study was to investigate the association between patient age and guideline adherence for prehospital care in emergency medical services (EMS) for moderate to severe trauma. METHODS: This was a retrospective observational study that used a nationwide EMS-based trauma database from 2016 to 2019. Adult trauma patients whose injury severity score was greater than or equal to nine were screened, and those with cardiac arrest or without outcome data were excluded. The enrolled patients were categorized into four groups according to patient age: young (<45 years), middle-aged (45-64 years), old (65-84 years), and very old (>84 years). The primary outcome was guideline adherence, which was defined as following all prehospital care components: airway management for level of consciousness below verbal response, oxygen supply for pulse oximetry under 94 %, intravenous fluid administration for systolic blood pressure under 90 mmHg, scene resuscitation time within 10 min, and transport to the trauma center or level 1 emergency department. Multivariable logistic regression was conducted to calculate the adjusted odds ratios (aORs) and 95 % confidence intervals (95 % CIs). RESULTS: Among the 430,365 EMS-treated trauma patients, 38,580 patients were analyzed-9,573 (24.8 %) in the young group, 15,296 (39.7 %) in the middle-aged group, 9,562 (24.8 %) in the old group, and 4,149 (10.8 %) in the very old group. The main analysis revealed a lower probability of guideline adherence in the old group (aOR 95 % CI = 0.84 (0.76-0.94)) and very old group (aOR 95 % CI = 0.68 (0.58-0.81)) than in the young group. CONCLUSION: We found disparities in guideline adherence for prehospital care according to patient age at the time of EMS assessment of moderate to severe trauma. Considering this disparity, the prehospital trauma triage and management for older patients needs to be improved and educated to EMS providers.

Development and Deployment of a Pre-planned Hospital Emergency Response Team (HERT) for EMS Augmentation: Case Report and Program Review.

With the establishment and growth of the Emergency Medical Services (EMS) subspecialty, significant attention has been focused on clinical activities performed by EMS physicians in the out-of-hospital environment. An EMS fellowship includes special operations education to develop preparedness for responding to field situations requiring physician expertise. With only a thousand Board Certified EMS physicians in North America, EMS physicians may not be available 24 hours per day to respond to field emergencies. Non-EMS physicians with minimal experience in prehospital or austere care may be called upon to respond to complex prehospital emergencies requiring advanced skills. The Los Angeles County EMS Agency implemented a policy in 1992 to establish Hospital Emergency Response Teams (HERT) as a regional resource to provide time-critical, specialized prehospital services within an EMS system (1). Activation of the HERT is rare, most frequently prompted by need for field amputation to enable extrication. We describe one such incident of a field intervention by HERT and detail the staffing, training, and equipment considerations within our large regional EMS system.

Prediction of the future number of fall-related emergency medical services calls in older individuals.

BACKGROUND: Falls among older individuals contribute significantly to the rise in ambulance transport use. To recognize the importance of future countermeasures, we estimated the projected number and percentage of fall-related emergency medical service (EMS) calls. METHODS: We examined the sex, age group, and location of falls among patients aged ≥ 65 years who contacted emergency services in Sapporo City from 2013 to 2021. Annual fall-related calls per population subgroup were calculated, and trends were analyzed. Four models were used to estimate the future number of fall-related calls from the 2025-2060 projected population: (1) based on the 2022 data, estimates from the 2013-2022 data using (2) Poisson progression, (3) neural network, (4) estimates from the 2013-2019 data using neural network. The number of all EMS calls was also determined using the same method to obtain the ratio of all EMS calls. RESULTS: During 2013-2022, 70,262 fall-related calls were made for those aged ≥ 65 years. The rate was higher indoors among females and outdoor among males in most age groups and generally increased with age. After adjusting for age, the rate increased by year. Future estimates of the number of fall calls are approximately double the number in 2022 in 2040 and three times in 2060, with falls accounting for approximately 11% and 13% of all EMS calls in 2040 and 2060, respectively. CONCLUSION: The number of fall-related EMS calls among older people is expected to increase in the future, and the percentage of EMS calls will also increase; therefore, countermeasures are urgently needed.

Video livestreaming from medical emergency callers' smartphones to emergency medical dispatch centres: a scoping review of current uses, opportunities, and challenges.

BACKGROUND: Timely dispatch of appropriate emergency medical services (EMS) resources to the scene of medical incidents, and/or provision of treatment at the scene by bystanders and medical emergency lay callers (referred to as 'callers' in this review) can improve patient outcomes. Currently, in dispatch systems worldwide, prioritisation of dispatch relies mostly on verbal telephone information from callers, but advances in mobile phone technology provide means for sharing video footage. This scoping review aimed to map and identify current uses, opportunities, and challenges for using video livestreaming from callers' smartphones to emergency medical dispatch centres. METHODS: A scoping review of relevant published literature between 2007 and 2023 in the English language, searched within MEDLINE; CINAHL and PsycINFO, was descriptively synthesised, adhering to the PRISMA extension for scoping reviews. RESULTS: Twenty-four articles remained from the initial search of 1,565 articles. Most studies were simulation-based and focused on emergency medical dispatchers' (referred to as 'dispatcher/s' in this review) assisted video cardiopulmonary resuscitation (CPR), predominantly concerned with measuring how video impacts CPR performance. Nine studies were based on real-life practice. Few studies specifically explored experiences of dispatchers or callers. Only three articles explored the impact that using video had on the dispatch of resources. Opportunities offered by video livestreaming included it being: perceived to be useful; easy to use; reassuring for both dispatchers and callers; and informing dispatcher decision-making. Challenges included the potential emotional impact for dispatchers and callers. There were also concerns about potential misuse of video, although there was no evidence that this was occurring. Evidence suggests a need for appropriate training of dispatchers and video-specific dispatch protocols. CONCLUSION: Research is sparse in the context of video livestreaming. Few studies have focussed on the use of video livestreaming outside CPR provision, such as for trauma incidents, which are by their nature time-critical where visual information may offer significant benefit. Further investigation into acceptability and experience of the use of video livestreaming is warranted, to understand the potential psychological impact on dispatchers and callers.

Effect of timing of advanced life support on out-of-hospital cardiac arrests at home in Japan.

AIM: In cases of out-of-hospital cardiac arrests (OHCA) occurring at home, Japanese emergency medical services personnel decide whether to provide treatment on the scene or during transport based on their judgment. This study aimed to evaluate the association between the timing of advanced life support (ALS) (i.e., endotracheal intubation [ETI] or adrenaline administration) for OHCA at home and prognosis. METHOD: This retrospective cohort study used data from the Japan Utstein Registry and emergency transport data collected from patients who underwent pre-hospital ETI (n = 6806) and received adrenaline (n = 22,636) between 2016 and 2019. The timing of ETI or adrenaline administration was determined as "on the scene" or "in the ambulance." Multiple logistic regression analysis was used to estimate the association among the timing of ALS implementation, pre-hospital return of spontaneous circulation (ROSC), and survival at 1 month. RESULT: ETI on the scene was significantly positively associated with pre-hospital ROSC (adjusted odds ratio [AOR], 1.81; 95% confidence interval [CI], 1.57-2.09) and survival at 1 month (AOR, 1.81; 95% CI, 1.47-2.23). Adrenaline administration on the scene was significantly positively associated with pre-hospital ROSC (AOR, 2.51; 95% CI, 2.33-2.70) and survival at 1 month (AOR, 2.13; 95% CI, 1.89-2.40). CONCLUSION: Our analysis suggests performing ALS on the scene was associated with pre-hospital ROSC and survival at 1 month. Further efforts are needed to increase the rate of ALS implementation on the scene by emergency life-saving technicians.

Evaluation of basic life support interventions for foreign body airway obstructions: A population-based cohort study.

AIM: To quantify the associations of foreign body airway obstruction (FBAO) basic life support (BLS) interventions with FBAO relief and survival to discharge. METHODS: We identified prehospital FBAO patient encounters in Alberta, Canada between Jan 1, 2018 and Dec 31,2021 using the provincial emergency medical services' medical records, deterministically linked to hospital data. Two physicians reviewed encounters to determine cases and extract data. Multivariable logistic regression determined the adjusted odds ratio of FBAO relief (primary outcome) and survival to discharge for the exposure of BLS interventions (abdominal thrusts [AT], chest compressions/thrusts [CC], or combinations) relative to back blows [BB]. Intervention-associated injuries were identified using International Classification of Diseases codes, followed by health records review. RESULTS: We identified 3,677 patient encounters, including 709 FBAOs requiring intervention. Bystanders performed the initial BLS intervention in 488 cases (77.4%). Bystanders and paramedics did not relieve the FBAO in 151 (23.5%) and 11 (16.7%) cases, respectively. FBAOs not relieved before paramedic arrival had a higher proportion of deaths (n = 4[0.4%] versus n = 92[42.4%], p < 0.001). AT and CC were associated with decreased odds of FBAO relief relative to BB (adjusted odds ratio [aOR] 0.49 [95%CI 0.30-0.80] and 0.14 [95%CI 0.07-0.28], respectively). CC were associated with decreased odds of survival to discharge (aOR 0.04 [95%CI 0.01-0.32]). AT, CC, and BB were implicated in intervention-associated injuries in four, nine, and zero cases, respectively. CONCLUSIONS: Back blows are associated with improved outcomes compared to abdominal thrusts and chest compressions. These data can inform prospective studies aimed at improving response to choking emergencies.

Follow up care for adults with diabetes treated for severe hypoglycemia by emergency medical Services, 2013-2019.

AIMS: To capture the types and content of healthcare encounters following severe hypoglycemia requiring emergency medical services (EMS) and to correlate their features with subsequent risk of severe hypoglycemia. METHODS: A retrospective cohort was obtained by linking data from a multi-state health system and an advanced life support ambulance service. This identified 1977 EMS calls by 1028 adults with diabetes experiencing hypoglycemia between 1/1/2013-12/31/2019. We evaluated the healthcare engagement over the following 7 days to identify rates of discussion of hypoglycemia, change of diabetes medications, glucagon prescribing, and referral for diabetes. RESULTS: Rates of hypoglycemia discussion increased with escalating levels of care, from 11.5 % after EMS calls without emergency department (ED) transport or outpatient clinical encounters to 98 % among hospitalized patients with outpatient follow-up. EMS transport and outpatient follow-up were associated with significantly higher odds of discussion of hypoglycemia (OR 60 and OR 22.1, respectively). Interventions were not impacted by previous severe hypoglycemia within 30 days. Prescription of glucagon was rare among all patients. CONCLUSIONS: Interventions to prevent recurrent hypoglycemia increase with escalating levels of care but remain inadequate and inconsistent with clinical guidelines. Greater attention is needed to ensure timely diabetes-related follow-up and treatment modification for patients experiencing severe hypoglycemia.

Ambulance service satisfaction level and associated factors among service users in Addis Ababa, Ethiopia.

INTRODUCTION: Pre-hospital ambulance service is the most important part of healthcare service. Client satisfaction with the service indicates the degree of adaptation to the appropriate quality and quantity of services. Patients' dissatisfaction with the service can affect their expectations of the overall services that they will receive later in the definitive care facility. However, it is not a well-addressed area in developing countries, including Ethiopia. OBJECTIVE: This study aimed to identify the ambulance service satisfaction level and associated factors among service users in Addis Ababa, Ethiopia. METHODS: A cross-sectional study was conducted in five governmental hospitals in Addis Ababa city. A face-to-face exit interview technique was employed on a total of 410 consecutively selected participants using a pretested tool developed from similar sources. The cleaned data was entered into the Epi-Data Manager 4.6 version and then exported to SPSS version 26 for analysis. The dependent variable was dichotomized into satisfied and unsatisfied to compute bivariate logistic regression. In the multivariate logistic regression model, predictors with a p-value < 0.05 at the 95% CI were considered to have a significant association. RESULT: A total of 410 respondents were included in the study. The mean of participants' responses regarding ambulance personnel, call operator, treatment on the scene, and ambulance subscale was 3.64, 3.48, 3.40, and 3.43, respectively. The study found that only 21.5% of participants were satisfied by the ambulance service they received. There was a statistically significant association between ambulance service satisfaction and age (AOR = 3.52, 95% CI: 1.01-12.36), monthly income (AOR = 3.13, 95% CI: 1.41-6.94), ambulance response time (AOR = 10.33, 95% CI: 2.09-51.06), type of ambulance used (AOR = 4.55, 95% CI: 2.19-9.43), and previous ambulance usage (AOR = 2.33, 95% CI: 1.34-4.05). CONCLUSION: The study found a low level of satisfaction among ambulance users. The findings suggest that ambulance personnel performance is a key determinant of user satisfaction, while treatment at the scene and in the ambulances, and call operator areas require improvement. Age, monthly income, ambulance response time, type of ambulance, and previous ambulance use also influenced satisfaction. Improving the quality of services, reducing response time, and ensuring call operators are trained are vital steps to enhance satisfaction.

Ventilation during cardiopulmonary resuscitation with mechanical chest compressions: How often are two insufflations being given during the 3-second ventilation pauses?

BACKGROUND: Mechanical chest compression devices in 30:2 mode provide 3-second pauses to allow for two insufflations. We aimed to determine how often two insufflations are provided in these ventilation pauses, in order to assess if prehospital providers are able to ventilate out-of-hospital cardiac arrest (OHCA) patients successfully during mechanical chest compressions. METHODS: Data from OHCA cases of the regional ambulance service of Utrecht, The Netherlands, were prospectively collected in the UTrecht studygroup for OPtimal registry of cardIAc arrest database (UTOPIA). Compression pauses and insufflations were visualized on thoracic impedance and waveform capnography signals recorded by manual defibrillators. Ventilation pauses were analyzed for number of insufflations, duration of the subintervals of the ventilation cycles, and ratio of successfully providing two insufflations over the course of the resuscitation. Generalized linear mixed effects models were used to accurately estimate proportions and means. RESULTS: In 250 cases, 8473 ventilation pauses were identified, of which 4305 (51%) included two insufflations. When corrected for non-independence of the data across repeated measures within the same subjects with a mixed effects analysis, two insufflations were successfully provided in 45% of ventilation pauses (95% CI: 40-50%). In 19% (95% CI: 16-22%) none were given. CONCLUSION: Providing two insufflations during pauses in mechanical chest compressions is mostly unsuccessful. We recommend developing strategies to improve giving insufflations when using mechanical chest compression devices. Increasing the pause duration might help to improve insufflation success.

Emergency Department Pediatric Mental and Behavioral Health Patients Transported by Emergency Medical Services and Police: Trends and Interventions.

OBJECTIVE: We aimed to understand transport utilization trends, demographics, emergency department (ED) interventions, and outcomes of pediatric mental and behavioral health (MBH) patients transported by emergency medical services (EMS), police, or self-transported. METHODS: This retrospective cohort study utilized electronic health record data from patients aged 5 to 18 years presenting with acute MBH conditions at 2 affiliated pediatric EDs from January 2012 to December 2020. Data included demographics, ED interventions for aggression/agitation, Brief Rating of Aggression by Children and Adolescents (BRACHA) scores, and ED dispositions. Descriptive statistics and comparative analyses were conducted using chi-square, Wilcoxon rank sum tests, and multivariable logistic regression. Linear regression analyzed trends. RESULTS: Of 440,302 ED encounters, 70,557 (16%) were for acute MBH concerns, with 14.6% transported by EMS and 5.9% by police. The proportion of MBH visits increased from 9.9% in 2012 to 19.8% in 2020 (95% (confidence interval) CI [0.7, 1.7], P = 0.0009), with a concurrent 0.4% annual increase in those transported by EMS (95% CI [0.2, 0.6], P = 0.006). MBH patients transported by EMS and police had significantly higher odds of requiring restraint in the ED and were more likely to have higher BRACHA scores and to be admitted compared to self-transported patients (all comparisons, P < 0.001). CONCLUSIONS: Pediatric MBH ED visits and EMS utilization are increasing. MBH patients transported by EMS and police may represent a more aggressive ED population. Given the rising encounters within this high-risk population, our EDs, EMS, and police need support and resources for safe pediatric MBH patient management.

Disparities in the accuracy of reporting opioid overdoses to 9-1-1 by race and sex of overdose victim, Marion County, Indiana, 2011-2020.

OBJECTIVES: To assess the prevalence of emergency medical incidents wherein naloxone was administered but overdose was not described as the chief complaint during the 9-1-1 call, including differences by overdose victim race/ethnicity and sex. METHODS: We computed the percentage of 9-1-1 calls in Marion County, Indiana, from 2011 to 2020, wherein naloxone was administered but the caller did not describe overdose as the chief complaint. We estimated a logistic regression to examine the associations between reporting of overdose as the chief complaint and race and sex of the overdose victim. RESULTS: Almost one-fifth of 9-1-1 calls preceding naloxone administration did not describe overdose as the chief complaint. 9-1-1 callers were more likely to describe a non-overdose as the chief complaint when the overdose victim was Black or female. CONCLUSION: 9-1-1 callers are less likely to use terminology describing overdose when the overdose victim is female or Black, than when the victim is male or White. Inaccurate terminology when calling 9-1-1 could delay naloxone administration, thereby increasing risk of overdose death and hypoxic brain injury. Some 9-1-1 callers may be avoiding overdose terminology to prevent a police response, or due to lack of knowledge about overdose identification, but further research is needed to determine the mechanisms underlying these findings.

Hazard Flagging as a Risk Mitigation Strategy for Violence against Emergency Medical Services.

Paramedics are increasingly being subjected to violence, creating the potential for significant physical and psychological harm. Where a patient has a history of violent behavior, hazard flags-applied either to the individual, their residential address, or phone number-can alert paramedics to the possibility of violence, potentially reducing the risk of injury. Leveraging a novel violence reporting process embedded in the electronic patient care record, we reviewed violence reports filed over a thirteen-month period since its inception in February 2021 to assess the effectiveness of hazard flagging as a potential risk mitigation strategy. Upon reviewing a report, paramedic supervisors can generate a hazard flag if recurrent violent behavior from the patient is anticipated. In all, 502 violence reports were filed, for which paramedic supervisors generated hazard flags in 20% of cases (n = 99). In general, cases were not flagged either because the incident occurred at a location not amenable to flagging or because the supervisors felt that a hazard flag was not warranted based on the details in the report. Hazard flagging was associated with an increased risk of violence during subsequent paramedic attendance (Odds Ratio [OR] 6.21, p < 0.001). Nevertheless, the process appears to reliably identify persons who may be violent towards paramedics.
