Rural and Ethnic Disparities in Out-of-hospital Care and Transport Pathways After Road Traffic Trauma in New Zealand.

Introduction: The out-of-hospital emergency medical service (EMS) care responses and the transport pathways to hospital play a vital role in patient survival following injury and are the first component of a well-functioning, optimised system of trauma care. Despite longstanding challenges in delivering equitable healthcare services in the health system of Aotearoa-New Zealand (NZ), little is known about inequities in EMS-delivered care and transport pathways to hospital-level care. Methods: This population-level cohort study on out-of-hospital care, based on national EMS data, included trauma patients <85 years in age who were injured in a road traffic crash (RTC). In this study we examined the combined relationship between ethnicity and geographical location of injury in EMS out-of-hospital care and transport pathways following RTCs in Aotearoa-NZ. Analyses were stratified by geographical location of injury (rural and urban) and combined ethnicity-geographical location (rural Maori, rural non-Maori, urban Maori, and urban non-Maori). Results: In a two-year period, there were 746 eligible patients; of these, 692 were transported to hospital. Indigenous Maori comprised 28% (196) of vehicle occupants attended by EMS, while 47% (324) of patients' injuries occurred in a rural location. The EMS transport pathways to hospital for rural patients were slower to reach first hospital (total in slowest tertile of time 44% vs 7%, P ≥ 0.001) and longer to reach definitive care (direct transport, 77% vs 87%, P = 0.001) compared to urban patients. Maori patients injured in a rural location were comparatively less likely than rural non-Maori to be triaged to priority transport pathways (fastest dispatch triage, 92% vs 97%, respectively, P = 0.05); slower to reach first hospital (total in slowest tertile of time, 55% vs 41%, P = 0.02); and had less access to specialist trauma care (reached tertiary trauma hospital, 51% vs 73%, P = 0.02). Conclusion: Among RTC patients attended and transported by EMS in NZ, there was variability in out-of-hospital EMS transport pathways through to specialist trauma care, strongly patterned by location of incident and ethnicity. These findings, mirroring other health disparities for Maori, provide an equity-focused evidence base to guide clinical and policy decision makers to optimize the delivery of EMS care and reduce disparities associated with out-of-hospital EMS care.

Analysis of barriers associated with emergency medical service activation in patients with acute stroke and acute myocardial infarction from Zhongjiang County of Sichuan Province in China.

OBJECTIVES: The purpose of this study was to investigate the preferred modes of transportation to the hospital among patients with acute stroke and acute myocardial infarction (AMI), as well as to identify the factors that influence the utilization of ambulances. METHODS: We conducted a cross-sectional study, including patients who were diagnosed with acute stroke and AMI, at the people's hospital of Zhongjiang, from September 30th, 2022 to August 30th, 2023. All patients were divided into emergency medical service (EMS)-activation group and self-transportation group. Chi-square and t-tests were utilized to discern differences between groups at baseline. To screen relevant variables, we employed the Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis using R package glmnet. Subsequently, we performed a logistic regression analysis to identify predictors of EMS activation according the results of LASSO regression. RESULTS: we collected 929 valid questionnaires. 26.16% of the patients required the services of EMS. 90.9% of individuals have not received any formal first aid education. 42.1% of them reported that they had no understanding of cardiovascular and cerebrovascular diseases. Diagnosed as AMI (OR 0.22, 95%CI 0.06 to 0.88) or acute cerebral infarction (OR 0.26, 0.10 to 0.68), the distance between the patient and the nearest 120 network hospital when the patient had these symptoms (OR 0.97, 0.94 to 0.99), the patient's son or daughter was there when the patient was symptomatic (OR 0.58, 0.37 to 0.94), the patient (OR 0.19, 0.05 to 0.72) and the patient's partner (wife or husband) (OR 0.36, 0.16 to 0.85) had decided that the patient needed further medical help, Among patients who did not seek immediate help after symptom onset, thinking that the symptoms will disappear spontaneously (OR 0.34, 0.13 to 0.92) or not wanting to disturb others (OR 0.06, 0.01 to 0.66) or believing that they are not important symptoms (OR 0.15, 0.05 to 0.42) were factors independently associated with less ambulance use. Age (OR 1.02, 1.00 to 1.04), Stroke patients have experienced symptoms of disturbance of consciousness or convulsions (OR 2.99, 1.72 to 5.2) were independent factors associated with increased ambulance use. CONCLUSION: There is still ambulance underutilization among patients with acute stroke and AMI in county territory of China. Moreover, it is needed to raise the level of first aid education and awareness about EMS. Additionally, private clinic doctors and the public should gain adequate understanding of the severity of acute stroke and AMI, as well as their common symptoms, the crucial importance of prompt medical intervention. Finally, we propose that all township hospitals should be integrated into the 120 emergency networks and equipped with emergency first aid capabilities, pre-hospital care, and transportation abilities.

Parallel activation of helicopter and ground transportation after dispatcher identification of suspected anterior large vessel occlusion stroke in rural areas: a proof-of-concept case with modeling from the LESTOR trial.

BACKGROUND: When stroke patients with suspected anterior large vessel occlusion (aLVO) happen to live in rural areas, two main options exist for prehospital transport: (i) the drip-and-ship (DnS) strategy, which ensures rapid access to intravenous thrombolysis (IVT) at the nearest primary stroke center but requires time-consuming interhospital transfer for endovascular thrombectomy (EVT) because the latter is only available at comprehensive stroke centers (CSC); and (ii) the mothership (MS) strategy, which entails direct transport to a CSC and allows for faster access to EVT but carries the risk of IVT being delayed or even the time window being missed completely. The use of a helicopter might shorten the transport time to the CSC in rural areas. However, if the aLVO stroke is only recognized by the emergency service on site, the helicopter must be requested in addition, which extends the prehospital time and partially negates the time advantage. We hypothesized that parallel activation of ground and helicopter transportation in case of aLVO suspicion by the dispatcher (aLVO-guided dispatch strategy) could shorten the prehospital time in rural areas and enable faster treatment with IVT and EVT. METHODS: As a proof-of-concept, we report a case from the LESTOR trial where the dispatcher suspected an aLVO stroke during the emergency call and dispatched EMS and HEMS in parallel. Based on this case, we compare the provided aLVO-guided dispatch strategy to the DnS and MS strategies regarding the times to IVT and EVT using a highly realistic modeling approach. RESULTS: With the aLVO-guided dispatch strategy, the patient received IVT and EVT faster than with the DnS or MS strategies. IVT was administered 6 min faster than in the DnS strategy and 22 min faster than in the MS strategy, and EVT was started 47 min earlier than in the DnS strategy and 22 min earlier than in the MS strategy. CONCLUSION: In rural areas, parallel activation of ground and helicopter emergency services following dispatcher identification of stroke patients with suspected aLVO could provide rapid access to both IVT and EVT, thereby overcoming the limitations of the DnS and MS strategies.

Development and psychometric testing of a scale to measure effective rural emergency transfer (RET).

BACKGROUND: The process of transferring patients from small rural primary care facilities to referral facilities impacts the quality of care and effectiveness of the referral healthcare system. The study aimed to develop and evaluate the psychometric properties of a scale measuring requirements for effective rural emergency transfer. METHODS: An exploratory sequential design was utilized to develop a scale designed to measure requirements for effective emergency transport. Phase one included a qualitative, interview study with 26 nursing transport providers. These transcripts were coded, and items developed for the proposed scale. Phase two included a content validity review by these 16 transport providers of the domains and items developed. Phase three included development and evaluation of psychometric properties of a scale designed to measure requirements for effective emergency transport. This scale was then tested initially with 84 items and later reduced to a final set of 58 items after completion by 302 transport nurses. The final scale demonstrated three factors (technology & tools; knowledge & skills; and organization). Each factor and the total score reported excellent scale reliability. RESULTS: The initial item pool consisted of 84 items, generated, and synthesized from an extensive literature review and the qualitative descriptive study exploring nurses' experiences in rural emergency patient transportation. A two-round modified Delphi method with experts generated a scale consisting of 58 items. A cross-sectional study design was used with 302 nurses in rural clinics and health in four rural health districts. A categorical principal components analysis identified three components explaining 63.35% of the total variance. The three factors, technology, tools, personal knowledge and skills, and organization, accounted for 27.32%, 18.15 and 17.88% of the total variance, respectively. The reliability of the three factors, as determined by the Categorical Principal Component Analysis (CATPCA)'s default calculation of the Cronbach Alpha, was 0.960, 0.946, and 0.956, respectively. The RET Cronbach alpha was 0.980. CONCLUSIONS: The study offers a three-factor scale to measure the effectiveness of emergency patient transport in rural facilities to better understand and improve care during emergency patient transport.

Neonatal therapeutic hypothermia in a regional swedish cohort: Adherence to guidelines, transport and outcomes.

AIM: Swedish guidelines for therapeutic hypothermia (TH) after perinatal asphyxia were established in 2007, following several randomised studies that demonstrated improved outcomes. We assessed the implementation of hypothermia treatment in a mid-Swedish region with a sizeable proportion of outborn infants. METHOD: A population-based TH cohort from 2007 to 2015 was scrutinised for adherence to national guidelines, interhospital transport, including the use of a cooling mattress made of phase change material for thermal management, and outcomes. RESULTS: Of 136 admitted infants, 99 (73 %) were born outside the hospital. Ninety-eight percent fulfilled the criteria for postnatal depression/acidosis, and all patients had moderate-to-severe encephalopathy. Treatment was initiated within 6 h in 85 % of patients; amplitude-integrated electroencephalography/electroencephalography was recorded in 98 %, cranial ultrasound in 78 %, brain magnetic resonance imaging in 79 %, hearing tests in all, and follow-up was performed in 93 %. Although target body temperature was attained later (p < 0.01) in outborn than in inborn infants, at a mean (standard deviations) age of 6.2 (3.2) h vs 4.4 (2.6) h, 40 % of those transported using the cooling mattress were already within the therapeutic temperature range on arrival, and few were excessively cooled. The mortality rate was 23 %, and 38 % of the survivors had neurodevelopmental impairment at a median of 2.5 years. CONCLUSION: The regionalisation of TH, including interhospital transport, was feasible and resulted in outcomes comparable to those of randomised controlled studies.

Neuromuscular Blocking Agent Use in Critical Care Transport Not Associated With Intubation.

OBJECTIVE: Variable indications exist for neuromuscular blocking agents (NMBAs) in the critical care transport setting beyond facilitation of intubation. METHODS: This retrospective cohort study included adult patients (≥ 18 years) who underwent critical care transport from July 1, 2020, to May 2, 2023, and received NMBAs during transport that was not associated with intubation. The primary outcome was the indication for NMBA administration. Secondary outcomes included the characterization of NMBA use, mean Richmond Agitation Sedation Scale score before NMBA administration, sedation strategy used, and continuation of NMBAs within 48 hours of hospital admission. RESULTS: One hundred twenty-six patients met the inclusion criteria. The most common indication for NMBA administration was ventilator dyssynchrony (n = 71, 56.4%). The majority of patients received rocuronium during transport (n = 113, 89.7%). The mean pre-NMBA Richmond Agitation Sedation Scale score was -3.7 ± 2.4. The most common sedation strategy was a combination of continuous infusion and bolus sedatives (76.2%). One hundred (79.4%) patients had sedation changes in response to NMBA administration. Seventy-two (57.1%) received NMBAs during the first 48 hours of their intensive care unit admission. CONCLUSION: NMBAs were frequently administered for ventilator dyssynchrony and continuation of prior therapy. Optimization opportunities exist to ensure adequate deep sedation and reassessment of NMBA indication.

Air or Ground Transport to the Critical Care Resuscitation Unit: Does It Really Matter?

OBJECTIVE: Critically ill patients requiring urgent interventions or subspecialty care often require transport over significant distances to tertiary care centers. The optimal method of transportation (air vs. ground) is unknown. We investigated whether air transport was associated with lower mortality for patients being transferred to a specialized critical care resuscitation unit (CCRU). METHODS: This was a retrospective study of all adult patients transferred to the CCRU at the University of Maryland Medical Center in 2018. Our primary outcome was hospital mortality. The secondary outcomes included the length of stay and the time to the operating room (OR) for patients undergoing urgent procedures. We performed optimal 1:2 propensity score matching for each patient's need for air transport. RESULTS: We matched 198 patients transported by air to 382 patients transported by ground. There was no significant difference between demographics, the initial Sequential Organ Failure Assessment score, or hospital outcomes between groups. One hundred sixty-four (83%) of the patients transported via air survived to hospital discharge compared with 307 (80%) of those transported by ground (P = .46). Patients transported via air arrived at the CCRU more quickly (127 [100-178] vs. 223 [144-332] minutes, P < .001) and were more likely (60 patients, 30%) to undergo urgent surgical operation within 12 hours of CCRU arrival (30% vs. 17%, P < .001). For patients taken to the OR within 12 hours of arriving at the CCRU, patients transported by air were more likely to go to the OR after 200 minutes since the transfer request (P = .001). CONCLUSION: The transportation mode used to facilitate interfacility transfer was not significantly associated with hospital mortality or the length of stay for critically ill patients.

Flight to Recovery: Impact of a Rooftop Helipad Air Ambulance Service at the Emergency University Hospital of Bucharest-A Caseload Analysis of the First 3 Years After Its Implementation.

OBJECTIVE: This observational study provides an overview of the implementation and impact of the helipad at the Bucharest Emergency University Hospital, Romania. The helipad, established in April 2019, is the only rooftop medical helipad in Bucharest authorized for day and night flights. Its influence extends beyond the local region, enabling the hospital to receive patients from various cities across Romania. The helipad has particularly strengthened the hospital's capabilities in cardiology, neurovascular emergencies, and neonatal care. Patients with acute myocardial infarctions or strokes can now be swiftly transported to the hospital for immediate intervention, whereas critically ill newborns can receive specialized care at the earliest stages of their lives. The objective of this article was to present a comprehensive timeline of the helipad's implementation and to demonstrate its transformative role in improving patient transportation, enhancing medical interventions, and elevating the overall efficiency of the health care facility. METHODS: The study is a retrospective regional caseload analysis based on data gathered from the Emergency Department of the University Emergency Hospital of Bucharest database. We included all 215 air transfer missions registered between December 2019 and December 2022, exactly 3 years apart from the beginning of the program. RESULTS: The findings provide valuable insights into patient demographics, case distribution, and trends, highlighting the importance of specialized medical interventions at the University Emergency Hospital of Bucharest. In particular, the mean age of patients treated at the hospital was 55.9 years, with a higher representation of males (156) than females (59). The average duration of hospitalization was 10.68 days. The study also examined transportation statistics, showing a decrease in the average number of transports per month over the years. Cardiologic cases accounted for the highest frequency (62.8%) among the analyzed categories followed by neurosurgery (8.8%) and neurologic cases (8.4%). CONCLUSION: The analysis provides important insights into patient demographics, case distribution, and trends. The findings highlight the significance of specialized medical interventions, particularly in cardiology and neurosurgery, which accounted for the majority of the cases. The implementation of the helipad has greatly improved patient transportation and facilitated timely medical assistance.

Mapping the processes and information flows of a prehospital emergency care system in Rwanda: a process mapping exercise.

OBJECTIVE: A vital component of a prehospital emergency care system is getting an injured patient to the right hospital at the right time. Process and information flow mapping are recognised methods to show where efficiencies can be made. We aimed to understand the process and information flows used by the prehospital emergency service in transporting community emergencies in Rwanda in order to identify areas for improvement. DESIGN: Two facilitated process/information mapping workshops were conducted. Process maps were produced in real time during discussions and shared with participants for their agreement. They were further validated by field observations. SETTING: The study took place in two prehospital care settings serving predominantly rural and predominantly urban patients. PARTICIPANTS: 24 healthcare professionals from various cadres. Field observations were done on 49 emergencies across both sites. RESULTS: Two maps were produced, and four main process stages were described: (1) call triage by the dispatch/call centre team, (2) scene triage by the ambulance team, (3) patient monitoring by the ambulance team on the way to the health facility and (4) handover process at the health facility. The first key finding was that the rural site had multiple points of entry into the system for emergency patients, whereas the urban system had one point of entry (the national emergency number); processes were otherwise similar between sites. The second was that although large amounts of information were collected to inform decision-making about which health facility to transfer patients to, participants found it challenging to articulate the intellectual process by which they used this to make decisions; guidelines were not used for decision-making. DISCUSSION: We have identified several areas of the prehospital care processes where there can be efficiencies. To make efficiencies in the decision-making process and produce a standard approach for all patients will require protocolising care pathways.

Implications of interhospital patient transfers for emergency medical services transportation systems in the Netherlands: a retrospective study.

OBJECTIVES: Interhospital patient transfers have become routine. Known drivers are access to specialty care and non-clinical reasons, such as limited capacity. While emergency medical services (EMS) providers act as main patient transfer operators, the impact of interhospital transfers on EMS service demand and fleet management remains understudied. This study aims to identify patterns in regional interhospital patient transfer volumes and their spatial distribution, and to discuss their potential implications for EMS service demand and fleet management. DESIGN: A retrospective study was performed analysing EMS transport data from the province of Drenthe in the Netherlands between 2013 and 2019 and public hospital listings. Yearly volume changes in urgent and planned interhospital transfers were quantified. Further network analysis, including geomapping, was used to study how transfer volumes and their spatial distribution relate to hospital specialisation, and servicing multihospital systems. Organisational data were considered for relating transfer patterns to fleet changes. SETTING: EMS in the province of Drenthe, the Netherlands, 492 167 inhabitants. PARTICIPANTS: Analyses are based on routinely collected patient data from EMS records, entailing all 248 114 transports (137 168 patients) of the Drenthe EMS provider (2013-2019). From these interhospital transports were selected (24 311 transports). RESULTS: Interhospital transfers represented a considerable (9.8%) and increasing share of transports (from 8.6% in 2013 to 11.3% in 2019). Most transfers were related to multihospital systems (47.3%, 11 509 transports), resulting in a considerable growth of planned EMS transports (from 2093 in 2013 to 3511 in 2019). Geomapping suggests increasing transfer distances and diminishing resource efficiencies due to lacking follow-up rides. Organisational data clarify how EMS fleets were adjusted by expanding resources and reorganising fleet operation. CONCLUSIONS: Emerging interhospital network transfers play an important role in EMS service demand. Increased interhospital transport volumes and geographical spread require a redesign of current EMS fleets and management along regional lines.

Detect, Dispatch, Drive: A Study of ShotSpotter Acoustic Technology and Transport of Gunshot Victims.

INTRODUCTION: Our previous work demonstrated that use of ShotSpotter (SS), a gunfire detection system, and use of police department (PD) transport decreased response and transport time for gunshot wound (GSW) victims versus events with non-ShotSpotter (NSS). The purpose of this study was to evaluate transport trends and how they are linked to SS in the period of 2016-2021 in Camden, NJ. METHODS: This was a single-center, retrospective observational study. Demographics, response time, transport time, and clinical data were collected. Independent t-test, Mann-Whitney U test, chi-squared test, and linear regression to correct for transport time and method of transport were used to compare outcomes (P < 0.05). RESULTS: A total of 267 GSWs were included: 77 emergency medical technicians (EMS)-SS, 41 EMS-NSS, 116 PD-SS, and 33 PD-NSS. When comparing response from 2016 to 2021, PD improved from 4 to 2 min (P = 0.001). EMS improved from 6.4 min (EMS-NSS) and 4.5 min (EMS-SS) to 5 min (EMS- NSS) and 4 min (EMS-SS) (P = 0.281). In addition, PD transport times, 5 min (SS) and 4 min (NSS), were faster than EMS, 9 min (SS and NSS) (P < 0.001). Overall PD transport volume increased with a peak in 2020 (68.3%). There was also an increase in PD-NSS transport 4% to 37.9% (P < 0.001). EMS-SS transport decreased from 54.7% to 6.9% (P < 0.001). CONCLUSION: The presence of SS technology in a small urban setting continues to be associated with a higher rate of PD transport of GSW victims. The critical time of dispatch and transport for both PD and EMS has shown durable improvement.

Enhancing Hospital Efficiency and Patient Care: Real-Time Tracking and Data-Driven Dispatch in Patient Transport.

Inefficient patient transport in hospitals often leads to delays, overworked staff, and suboptimal resource utilization, ultimately impacting patient care. Existing dispatch management algorithms are often evaluated in simulation environments, raising concerns about their real-world applicability. This study presents a real-world experiment that bridges the gap between theoretical dispatch algorithms and real-world implementation. It applies process capability analysis at Taichung Veterans General Hospital in Taichung, Taiwan, and utilizes IoT for real-time tracking of staff and medical devices to address challenges associated with manual dispatch processes. Experimental data collected from the hospital underwent statistical evaluation between January 2021 and December 2021. The results of our experiment, which compared the use of traditional dispatch methods with the Beacon dispatch method, found that traditional dispatch had an overtime delay of 41.0%; in comparison, the Beacon dispatch method had an overtime delay of 26.5%. These findings demonstrate the transformative potential of this solution for not only hospital operations but also for improving service quality across the healthcare industry in the context of smart hospitals.

Lastly, physiologic considerations, which are important to both AMT crews and receiving clinicians, are reviewed.

Critical Care Services for Pregnant Patients in Ontario: A Province-Wide Survey.

Critically ill pregnant patients require advanced critical care support, but access to these services is variable. We surveyed active Ontario obstetric facilities regarding critical care access. Responses were received from 44 of 80 obstetric units (55%), 13 (30%) being rural. Transport to another facility was required by 59% (majority >1 hour transport time), and differences were noted in the availability of specialty support services such as anesthesia and internal/obstetric medicine, as well as radiology and laboratory facilities, and use of massive transfusion protocols. Training in early supportive care of obstetric complications and optimized facility transport are areas for potential improvement.

Transportation and equipment needs for emergency medical services development in low- and middle-income countries.

Prehospital emergency medical services play a vital role in reducing mortality and disease burden in low- and middle-income countries. However, the availability of adequate prehospital emergency care remains a significant challenge in many resource-limited communities, with over 91% of the African population lacking access to sufficient emergency medical services. This commentary aims to highlight the critical components of transportation infrastructure and medical supply chain challenges for emergency medical service development and propose potential solutions for future study. Transportation is a key factor influencing prehospital mortality, yet many low- and middle-income countries face issues related to timely prehospital transportation, with patients often relying on family members or private vehicles for transportation, leading to delays in reaching healthcare facilities due to poor road infrastructure. Dysfunctional and inadequate vehicles are also common barriers to timely care. Response times and transport times often exceed high-income standards, with some rural areas experiencing total prehospital time, defined as the time of injury to arrival at definitive care, exceeding 24 hours. To address these transportation challenges, some low- and middle-income countries have developed tier-1 emergency medical services programs that use existing transportation infrastructure and involve lay first responders using motorized and non-motorized vehicles. These programs prioritize rapid transportation over advanced on-scene intervention, potentially providing faster response times. A combination of tier-1 and tier-2 emergency medical services systems, as seen in some successful examples, allows for early on-scene guidance and resource allocation. In addition to transportation, the availability of medical equipment is crucial for effective prehospital interventions, particularly in tier-2 systems. However, low- and middle-income countries often face shortages of even basic supplies, limiting the scope of care that emergency medical services personnel can provide. Developing tier-2 emergency medical services upon a foundation of tier-1 prehospital care utilizing sustainable local supply chains and common household items for basic care can help alleviate these equipment challenges. The integration of tier-1 and tier-2 systems may offer a promising solution to address resource limitations and improve timely access to emergency care in low- and middle-income countries. Further research and investment are required to explore and implement these solutions, ultimately reducing mortality and enhancing healthcare services in resource-limited communities.

Perspectives from military neonatal transport: past, present, and future.

This article traces the historical development of neonatal transport, from ancient Greek mythology to the modern era, with a particular focus on the contributions of U.S. military aviation. The narrative begins with early efforts in thermoregulation through stationary incubators and progresses to the pivotal role of aerial hospitals during World War II. Post-WWII, the establishment of neonatal transport services in New York and advancements in incubator technology set the stage for further innovation. The U.S. military's involvement in neonatal transport, initiated in the 1970s, witnessed significant milestones, including the adaptation of ECMO technology for air transport. The narrative unfolds through the lens of U.S. military neonatology in the Western Pacific, particularly at Clark Air Base. The article concludes with insights into the U.S. Indo-Pacific Command's neonatal transport mission, highlighting challenges faced during the SARS-CoV-2/COVID-19 pandemic and the development of specialized infection containment transport systems.

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.

Predictive modelling of transport decisions and resources optimisation in pre-hospital setting using machine learning techniques.

BACKGROUND: The global evolution of pre-hospital care systems faces dynamic challenges, particularly in multinational settings. Machine learning (ML) techniques enable the exploration of deeply embedded data patterns for improved patient care and resource optimisation. This study's objective was to accurately predict cases that necessitated transportation versus those that did not, using ML techniques, thereby facilitating efficient resource allocation. METHODS: ML algorithms were utilised to predict patient transport decisions in a Middle Eastern national pre-hospital emergency medical care provider. A comprehensive dataset comprising 93,712 emergency calls from the 999-call centre was analysed using R programming language. Demographic and clinical variables were incorporated to enhance predictive accuracy. Random Forest (RF), Support Vector Machine (SVM), Extreme Gradient Boosting (XGBoost), and Adaptive Boosting (AdaBoost) algorithms were trained and validated. RESULTS: All the trained algorithm models, particularly XGBoost (Accuracy = 83.1%), correctly predicted patients' transportation decisions. Further, they indicated statistically significant patterns that could be leveraged for targeted resource deployment. Moreover, the specificity rates were high; 97.96% in RF and 95.39% in XGBoost, minimising the incidence of incorrectly identified "Transported" cases (False Positive). CONCLUSION: The study identified the transformative potential of ML algorithms in enhancing the quality of pre-hospital care in Qatar. The high predictive accuracy of the employed models suggested actionable avenues for day and time-specific resource planning and patient triaging, thereby having potential to contribute to pre-hospital quality, safety, and value improvement. These findings pave the way for more nuanced, data-driven quality improvement interventions with significant implications for future operational strategies.
