Dynamics of geriatric emergency care: comprehensive assessment of emergency medical services utilization and its impact on healthcare resources in coastal India

Emergency Medical Services (EMS) transport significantly influences demographics, admission rates, and mortality among geriatric patients presenting to the Emergency Department (ED). The study evaluated geriatric patients aged 65 years and older, focusing on the impact of transport methods—EMS versus walk-ins—on demographics, admission rates, and mortality outcomes, aiming to identify key areas for improving emergency care delivery for this vulnerable population. Of the total patients, 8.5% were transported by EMS who were predominantly male and more likely to arrive during weekends and nighttime hours. Admission rates were significantly higher in the EMS group, with 30.6% requiring ICU care compared to 5.9% of walk-ins. Mortality rates were also markedly elevated among EMS patients (4.7% vs. 0.3%). The reasons for ED visits varied, with trauma being more frequent in EMS arrivals. This study underscores the critical impact of transport methods on patient outcomes, emphasizing the need to optimize EMS protocols and triage practices. Addressing these factors can enhance care delivery and improve admission and mortality outcomes for geriatric patients in ED settings.

A Scoping Review and Consensus Recommendations for Emergency Medical Services Buprenorphine (EMS-Bupe) Programs

Objectives Emergency Medical Services (EMS) agencies are beginning to provide low-barrier access to treatment for opioid use disorder (OUD) through the development of EMS buprenorphine (EMS-Bupe) programs. However, evidence-based practices for these programs are lacking. Our aim was to review the current literature on EMS and emergency department (ED) based buprenorphine treatment programs to provide consensus recommendations on the EMS-Bupe program development. Methods We performed a scoping review of EMS-Bupe programs and ED medication for OUD (MOUD) programs. We searched Ovid MEDLINE(R), Embase.com, Cochrane Central Register of Controlled Trials and Web of Science (Science Citation Index) for English language articles and abstracts. Additional articles/abstracts as identified independently by coauthors were added. Recommendations were generated through consensus based on the findings of the scoping review and other relevant literature. Results We identified a total of 9 EMS-Bupe articles/abstracts and 21 ED MOUD abstract, representing 5 EMS-Bupe programs in 4 states. There was significant variability between programs, from infrastructure, medication dosing, and retention rates. Results and recommendations were grouped into 8 categories: EMS program infrastructure, withdrawal classification thresholds, EMS protocol inclusion/exclusion criteria, buprenorphine dosing and adjunct medications, EMS disposition and scene times, EMS clinician training, referrals, and EMS data collection and quality management. Conclusions The EMS-Bupe program data are limited but show important variability. In general, we recommend that programs respond to community needs by establishing relationships with local resources. We also favor protocols that increase patient eligibility and treatment retention. Lastly, programs should consider low-barrier, patient-centered strategies aimed at preventing gaps in treatment.

Impact of epinephrine on neurological outcomes in out-of-hospital cardiac arrest after automated external defibrillator use in Japan

OHCA (out-of-hospital cardiac arrest) patients have improved neurological outcomes with public-access automated external defibrillator (PAD) use. However, the benefit of epinephrine administration after PAD use remains controversial. The purpose of the study was to investigate the impact of epinephrine administration on neurological outcomes in OHCA patients after PAD use. This study assessed 2,059,417 patients from the All-Japan Utstein Registry between 2005 and 2021. Patients were categorized into two groups: shockable and non-shockable rhythms on emergency medical service (EMS) arrival. Propensity score matching was used to adjust for various confounders and to analyze the impact of epinephrine administration on one-month favorable neurological outcomes. Criteria for bystander PAD was met by 11,629 (0.56%) of the enrolled patients. The mean age was 70 years with 71.9% male. Among them, 38.6% had shockable rhythms and 61.4% had non-shockable rhythms. After the matching, epinephrine administration negatively affected one-month favorable neurological outcome in patients with both shockable (14.7% vs. 41.1%, OR = 0.24, 95% CI = 0.19–0.31) and non-shockable rhythms (3.6% vs. 10.8%, OR = 0.31, 95% CI = 0.23–0.42). These findings suggest that epinephrine administration did not improve neurological outcomes in patients with OHCA after PAD use, providing insights to optimize EMS protocols for OHCA.

Evaluation of pre- and in-hospital workflows and time intervals with acute ischemic stroke patients.

Stroke is one of the leading causes of death and disability globally. Rapid recanalization therapy for acute ischemic stroke (AIS) patients is critical for improving outcome. While in-hospital time intervals have decreased and treatment methods have improved over the past decade, pre-hospital time intervals have remained unchanged. This study aims to develop a comprehensive understanding of the prognosis of AIS patients based on pre-hospital and in-hospital data. A retrospective study was conducted in Southwest Finland covering the period of 01/01/2022-31/12/2022. The study included a total of 174 AIS patients who were conveyed by the emergency medical services (EMS) to Turku University Hospital (TUH) and given intravenous thrombolysis (IVT) and/or endovascular treatment (EVT). Pre- and in-hospital care records of AIS patients were analyzed to evaluate workflows, time intervals, and the impacts of these time intervals on patient outcome. Binary logistic regression analysis was utilized to identify predictors of on-scene time (OST) and favorable outcome. The median OST for EMS was 19 minutes. Analysis indicated that the scene of the stroke event being an apartment building, barriers to care such as a locked door, vertigo as a symptom, and EMS taking measurements on-scene were predictive of longer OST. Longer OST was observed to negatively impact patient outcome, along with symptom severity and gender. Using the stroke code as the dispatch code and positive FAST signs were associated with shorter OST. In-hospital median door to needle time (DNT) was 14 minutes in the IVT group and 11 minutes in the IVT+EVT group. EMS prenotification was associated with shorter in-hospital time intervals. The presence of vertigo as a symptom poses challenges to identification by EMS. Pre-hospital OST meets national targets, but EMS workflows could be optimized to reduce OST and thereby positively influence patient outcome. These findings underscore the need for targeted interventions in EMS protocols to improve stroke care outcomes.

Variability of Prehospital Pain Management Protocols: A Review of Prehospital Care Protocols in the United States.

We describe emergency medical services (EMS) protocols for pain management in the United States to elucidate systemic variability in protocols. We describe types of pain medications included in protocols, routes of administration, indications for use, standing orders for dosing, and use in pediatric patients. We performed a review of all publicly accessible EMS protocols from the website http://www.emsprotocols.org, supplemented with internet searches. Data were abstracted into a data collection form from June 2021 to January 2022. We developed categories of responses to summarize the data, using frequencies and proportions to describe outcome measures. We reviewed 104 EMS protocols, spanning 43 states. The most common pain management medications include fentanyl (94.2%), morphine (70.2%), ketamine (61.5%), ketorolac (40.4%), oral acetaminophen (36.5%), oral ibuprofen (22.1%), and nitrous oxide (19.2%). The most common route of administration across all protocols and medications is intravenous. Severe pain, without a specified level, is the most common indication for fentanyl (65.3%), morphine (61.6%), ketorolac (50.0%), and nitrous oxide (40.0%). Musculoskeletal injuries and burns are the most common indications for morphine, 15.1% and 19.2% of protocols, respectively. The majority of protocols dictate the weight-based dosing of fentanyl (74.5%), morphine (64.4%), ketamine (87.3%), oral acetaminophen (56.8%), and oral ibuprofen (59.1%). However, 97.6% and 100.0% of protocols dictate a fixed dose of ketorolac and nitrous oxide, respectively. Fentanyl, morphine, oral acetaminophen, and oral ibuprofen can be administered to pediatric patients based on standing orders among >90.0% of protocols. However, only 46.2% and 75.0% of protocols allow the use of ketorolac and nitrous oxide in pediatric patients, respectively. We found variability in EMS pain management protocols including the types of allowed medications, routes of administration, dosing, and indications for use. Further studies may assess whether standardized protocols across EMS systems could improve patient safety and quality of care.

Barriers and Enablers in Prehospital Pediatric Analgesia

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.

Correlation Between EtCO2 and PCO2 in Patients Undergoing Critical Care Transport

Objectives End-tidal carbon dioxide (EtCO2) monitoring is widely used as a surrogate for the partial pressure of carbon dioxide (PCO2) in critically ill patients receiving manual or mechanical ventilation in prehospital, emergency, and critical care settings. Specific targets for ETCO2 are a key component of Emergency Medical Services (EMS) protocols, especially for specific patient groups such as those with traumatic brain injury. However, the correlation between EtCO2 and venous or arterial PCO2 is uncertain. We aimed to assess the correlation between EtCO2 and PCO2 in intubated patients undergoing critical care transport (CCT), and in specific subgroups of patients. Methods We performed a retrospective review of patients undergoing emergency transport by a multi-state CCT agency. Patients were included if they had an advanced airway and both an EtCO2 and PCO2 reading within 5 min of each other. We obtained data on patient demographics, transport characteristics, medical categories, vital signs, lab values, and specific interventions. We performed univariable and multivariable binary logistic regression to assess the association between delta PCO2 and these characteristics. Results We included 6,459 patients (mean age 58.4 years [SD 18.5], 57.1% male), of which a subset of 551 patients had multiple EtCO2-PCO2 measurements within 5 min. The median (IQR) initial delta PCO2 was 12.9 mmHg (7.1, 21.9). 3,967 (61.4%) patients had a delta PCO2 >10 mmHg and 1,843 (28.5%) had a delta PCO2 >20 mmHg. We identified an independent association between delta PCO2 >10 mmHg and age, male sex, interfacility transport, venous sampling site, respiratory rate, hypotension, hypoxia, and thoracostomy. In patients with multiple blood gas measurements, 76% had delta PCO2 >10 mmHg over the duration of the transport. Conclusions We identified substantial differences between EtCO2 and PCO2 across patients with medical and traumatic conditions undergoing critical care transport. The PCO2 assessment should be strongly considered as part of ventilatory management in patients encountered in emergency and critical care settings.

Implementing telemedicine with 5G technologies in a nursing home for reducing emergency admissions– study protocol of a mixed-methods study

BackgroundBy transmitting various types of data, telemedical care enables the provision of care where physicians and patients are physically separated. In nursing homes, telemedicine has the potential to reduce hospital admissions in nonemergency situations. In this study, telemedicine devices were implemented with the new 5G mobile communications standard in selected wards of a large nursing home in Northwest Germany. The main aim of this study is to investigate which individual and organizational factors are associated with the use of telemedicine devices and how users perceive the feasibility and implementation of such devices. Moreover, it is investigated whether the telemedical devices help to reduce the number of emergency admissions.MethodsTelemedicine devices are implemented over an 18-month period using a private 5G network, and all users receive training. This study uses qualitative and quantitative methods: To assess the individual and organizational factors associated with the use of telemedicine devices, survey data from employees before and after the implementation of these devices are compared. To assess the perception of the implementation process as well as the feasibility and usability of the telemedical devices, the nursing staff, physicians, medical assistants and residents are interviewed individually. Moreover, every telemedicine consultation is evaluated with a short survey. To assess whether the number of emergency admissions decreased, data from one year before implementation and one year after implementation are compared. The data are provided by the integrated dispatch centre and emergency medical services (EMS) protocols. The interview data are analysed via structured qualitative content analysis according to Kuckartz. Survey data are analysed using multivariable regression analysis.DiscussionLearnings from the implementation process will be used to inform future projects implementing telemedicine in care organizations, making the final telemedicine implementation and care concept available to more nursing homes and hospitals. Moreover, the study results can be used to provide use cases for appropriate and targeted application of telemedicine in nursing homes and to define the role of 5G technologies in these use cases. If the intervention is proven successful, the results will be used to promote 5G network rollout.Trial registrationGerman Clinical Trials Register – trial registration number: DRKS00030598.

Optimizing Prehospital Stroke Diagnosis: Integrating Machine Learning with the FAST Scoring System

Strokes are a leading cause of disability and death worldwide, and timely diagnosis is critical for effective treatment. Prehospital stroke diagnosis by emergency medical services (EMS) is essential for ensuring prompt care. The FAST (Face, Arms, Speech, and Time) scoring system is a common tool used to identify stroke symptoms quickly. However, the traditional FAST system has limitations, including reliance on subjective assessments and potential misdiagnoses due to symptom variability. This study aims to optimize the FAST scoring system and compare its performance with various machine learning models to enhance stroke prediction accuracy. A dataset from an ambulance service, including prehospital data such as age, sex, and FAST test results, was used. Data preprocessing involved handling missing values, encoding categorical variables, and applying the Synthetic Minority Over-sampling Technique (SMOTE) to balance the dataset. A grid search was conducted to test different weighting schemes for the FAST system. Machine learning models, including Logistic Regression, Random Forest, Support Vector Machine (SVM), XGBoost, and Decision Tree, were trained and evaluated using cross-validation on the training set and tested on a separate test set. The traditional FAST system showed an accuracy of 62.95%. Optimizing the FAST system through grid search marginally increased accuracy to 64.36%. However, machine learning models, particularly Random Forest, significantly outperformed the FAST system, achieving a test set accuracy of 88.54%. XGBoost also demonstrated strong performance with an accuracy of 77.07%, while Logistic Regression, SVM, and Decision Tree showed lower accuracies. These findings suggest that integrating machine learning models into EMS protocols could substantially improve the accuracy of prehospital stroke diagnosis, leading to quicker and more accurate identification and treatment of stroke patients. Although the optimized FAST system offers slight improvements, machine learning models present a promising avenue for enhancing stroke prediction and improving patient outcomes in emergency settings while acknowledging practicality issues.

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.

When Should EMS Call a Child a Small Adult: Inconsistency in Protocol Definitions

Age may be a factor in Emergency Medical Services (EMS) treatment of patients, and understanding of age-related patient differences is important to those providing care in the prehospital environment. The US Health Resources and Services Administration’s Maternal Child Health Bureau (HRSA MCHB) through their Emergency Medical Services for Children (EMSC) program has coordinated a focus on pediatric EMS care. However, there is a wide variety of age and other categorizations used to define the pediatric EMS population. This paper reviews the current state of pediatric EMS categorization from several sources, including national-level agencies and organizations, EMS Protocols, and other sources, and provides an overview of the anatomic, physiologic, and behavioral parameters that are generally expected within the range of pediatric ages. We found that, of 32 states publishing statewide EMS protocols online, there was great variability in the definition of a pediatric patient. The age at which states identified the transition from pediatric to adult patient ranged from 12-18 years old, and several states used non-aged-based definitions.

Advancing Emergency Medical Services’ (EMS) Response Capability for Behavioral Health Emergencies: Los Angeles County’s Performance Improvement Initiative

Introduction Behavioral health emergencies (BHEs) are a common patient encounter for emergency medical services (EMS) clinicians and other first responders, in particular law enforcement (LE) officers. It is critical for EMS clinicians to have management strategies for BHEs, yet relatively little information exists on best practices. In 2016, the Los Angeles County EMS Agency’s Commission initiated a comprehensive evaluation of the 9-1-1 response for BHEs and developed a plan for improving the quality of care and safety for patients and first responders. Methods A Behavioral Health Initiative Committee was assembled with broad representation from EMS, LE, health agencies, and the public. Committee objectives included: 1) produce a process map of the BHE response from the time of a 9-1-1 call to patient arrival at transport destination, 2) identify and describe the different agencies that respond, 3) describe the critical decision points in the EMS and LE field responses, 4) acquire data that quantitatively and/or qualitatively describe the services available, and 5) recommend interventions for system performance improvement. Results The committee generated comprehensive process maps for the prehospital response to BHEs, articulated principles for evaluation, and described key observations of the current system including: 9-1-1 dispatch criteria are variable and often defaults to a LE response, the LE response inadvertently criminalizes BHEs, EMS field treatment protocols for BHEs (and especially agitated patients) are limited, substance use disorder treatment lacks integration, destination options differ by transporting agency, and receiving facilities’ capabilities to address BHEs are variable. Recommendations for performance improvement interventions and initial implementation steps included: standardize dispatch protocols, shift away from a LE primary response, augment EMS treatment protocols for BHEs and the management of agitation, develop alternate destination for EMS transport. Conclusion This paper describes a comprehensive performance improvement initiative in LAC-EMSA’s 9-1-1 response to BHEs. The initiative included a thorough current state analysis, followed by future state mapping and the implementation of interventions to reduce LE as the primary responder when an EMS response is often warranted, and to improve EMS protocols and access to resources for BHEs.

Emergency Medical Services Protocols for Assessment and Treatment of Patients with Ventricular Assist Devices.

Patients with ventricular assist devices (VADs) represent a growing population presenting to Emergency Medical Services (EMS), but little is known about their prehospital care. This study aimed to characterize current EMS protocols in the United States for patients with VADs. States with state-wide EMS protocols were included. Protocols were obtained from the state EMS website. If not available, the office of the state medical director was contacted. For each state, protocols were analyzed for patient and VAD assessment and treatment variables. Of 32 states with state-wide EMS protocols, 21 had VAD-specific protocols. With 17 (81%) states noting a pulse may not be palpable, protocols recommended assessing alternate measures of perfusion and mean arterial pressure (MAP; 15 [71%]). Assessment of VAD was advised through listening for pump hum (20 [95%]) and alarms (20 [95%]) and checking the power supply (15 [71%]). For treatment, EMS prehospital consultation was required to begin chest compression in three (14%) states, and mechanical (device) chest compressions were not permitted in two (10%) states. Contact information for VAD coordinator was listed in a minority of five (24%) states. Transport of VAD equipment/backup bag was advised in 18 (86%) states. This national analysis of EMS protocols found VAD-specific EMS protocols are not universally adopted in the United States and are variable when implemented, highlighting a need for VAD teams to partner with EMS agencies to inform standardized protocols that optimize these patients' care.

Policy implementation strategies to address rural disparities in access to care for stroke patients.

Stroke systems of care (SSOC) promote access to stroke prevention, treatment, and rehabilitation and ensure patients receive evidence-based treatment. Stroke patients living in rural areas have disproportionately less access to emergency medical services (EMS). In the United States, rural counties have a 30% higher stroke mortality rate compared to urban counties. Many states have SSOC laws supported by evidence; however, there are knowledge gaps in how states implement these state laws to strengthen SSOC. This study identifies strategies and potential challenges to implementing state policy interventions that require or encourage evidence-supported pre-hospital interventions for stroke pre-notification, triage and transport, and inter-facility transfer of patients to the most appropriate stroke facility. Researchers interviewed representatives engaged in implementing SSOC across six states. Informants (n = 34) included state public health agency staff and other public health and clinical practitioners. This study examined implementation of pre-hospital SSOCs policies in terms of (1) development roles, processes, facilitators, and barriers; (2) implementation partners, challenges, and solutions; (3) EMS system structure, protocols, communication, and supervision; and (4) program improvement, outcomes, and sustainability. Challenges included unequal resource allocation and EMS and hospital services coverage, particularly in rural settings, lack of stroke registry usage, insufficient technologies, inconsistent use of standardized tools and protocols, collaboration gaps across SSOC, and lack of EMS stroke training. Strategies included addressing scarce resources, services, and facilities; disseminating, training on, and implementing standardized statewide SSOC protocols and tools; and utilizing SSOC quality and performance improvement systems and approaches. This paper identifies several strategies that can be incorporated to enhance the implementation of evidence-based stroke policies to improve access to timely stroke care for all patient populations, particularly those experiencing disparities in rural communities.
