Abstract
BACKGROUND AND IMPORTANCE Suboptimal acute pain care has been previously reported to be associated with demographic characteristics. OBJECTIVES The aim of this study was to assess a healthcare system's multi-facility database of emergency attendances for abdominal pain, to assess for an association between demographics (age, sex, and ethnicity) and two endpoints: time delay to initial analgesia (primary endpoint) and selection of an opioid as the initial analgesic (secondary endpoint). DESIGN, SETTING, AND PARTICIPANTS This retrospective observational study assessed four consecutive months' visits by adults (≥18 years) with a chief complaint of abdominal pain, in a UK National Health Service Trust's emergency department (ED). Data collected included demographics, pain scores, and analgesia variables. OUTCOME MEASURES AND ANALYSIS Categorical data were described with proportions and binomial exact 95% confidence intervals (CIs). Continuous data were described using median (with 95% CIs) and interquartile range (IQR). Multivariable associations between demographics and endpoints were executed with quantile median regression (National Health Service primary endpoint) and logistic regression (secondary endpoint). MAIN RESULTS In 4231 patients, 1457 (34.4%) receiving analgesia had a median time to initial analgesia of 110 min (95% CI, 104-120, IQR, 55-229). The univariate assessment identified only one demographic variable, age decade ( P = 0.0001), associated with the time to initial analgesia. Association between age and time to initial analgesia persisted in multivariable analysis adjusting for initial pain score, facility type, and time of presentation; for each decade increase the time to initial analgesia was linearly prolonged by 6.9 min (95% CI, 1.9-11.9; P = 0.007). In univariable assessment, time to initial analgesia was not associated with either detailed ethnicity (14 categories, P = 0.109) or four-category ethnicity ( P = 0.138); in multivariable analysis ethnicity remained non-significant as either 14-category (all ethnicities' P ≥ 0.085) or four-category (all P ≥ 0.138). No demographic or operational variables were associated with the secondary endpoint; opioid initial choice was associated only with pain score ( P = 0.003). CONCLUSION In a consecutive series of patients with abdominal pain, advancing age was the only demographic variable associated with prolonged time to initial analgesia. Older patients were found to have a linearly increasing, age-dependent risk for prolonged wait for pain care.

Abstract
INTRODUCTION Older adults are at high risk of adverse health outcomes in the post-emergency department (ED) discharge period. Prior work has shown that discharged older adults have variable understanding of their discharge instructions which may contribute to these outcomes. To identify discharge comprehension gaps amenable to future interventions, we utilize meta-analysis to determine patient comprehension across five domains of discharge instructions: diagnosis, medications, self-care, routine follow-up, and return precautions. METHODS Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, two reviewers sourced evidence from databases including Medline (PubMed), EMBASE, Web of Science, CINAHL, and Google Scholar (for gray literature). Publications or preprints appearing before April 2024 were included if they focused on geriatric ED discharge instructions and reported a proportion of patients with comprehension of at least one of five predefined discharge components. Meta-analysis of eligible studies for each component was executed using random-effects modeling to describe the proportion of geriatric ED cases understanding the discharge instructions; where appropriate we calculated pooled estimates, reported as percentages with 95% confidence interval (CI). RESULTS Of initial records returned (N = 2898), exclusions based on title or abstract assessment left 51 studies for full-text review; of these, seven constituted the study set. Acceptable heterogeneity and absence of indication of publication bias supported pooled estimates for proportions comprehending instructions on medications (41%, 95% CI 31%-50%, I2 = 43%), self-care (81%, 95% CI 76%-85%, I2 = 43%), and routine follow-up (76%, 95% CI 72%-79%, I2 = 25%). Key findings included marked heterogeneity with respect to comprehending two discharge parameters: diagnosis (I2 = 73%) and return precautions (I2 = 95%). CONCLUSIONS Older patients discharged from the ED had greater comprehension of self-care and follow-up instructions than about their medications. These findings suggest that medication instructions may be a priority domain for future interventions.

Abstract
OBJECTIVE The purpose of this scoping review was to identify and characterize helicopter emergency medical services (HEMS) outcomes literature from 2023, with the goal of describing updates to the Critical Care Transport Collaborative Outcomes Research Effort HEMS Outcomes Assessment Research Database (HOARD). METHODS Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines, a multireviewer approach was used to source and review articles published or in preprint databases from 2023. The articles included assessed a patient-centered outcome for HEMS versus a non-HEMS control group. Article characteristics included the journal impact factor (JIF), diagnostic group (trauma or nontrauma), and geographic origin. Categoric analyses comparing 2023 studies with HOARD studies from the previous decade (2013-2022) were executed with the Fisher exact test; nonnormal JIF data were described using median and interquartile range and analyzed (vs 2013-2022) with rank sum testing. RESULTS Of the initial records (N = 4,486), 4,410 were screened out, leaving 76 for full-text review. Of these, 58 were discarded, and 18 were classified as eligible for addition to HOARD. Most studies (14/18, 78%) focused on trauma, and an equally high proportion (14/18, 78%) came from North America. The median JIF was 2.4 (interquartile range, 1.2-3.6). Compared with HOARD studies from the previous decade, 2023 studies were similar with respect to diagnostic focus (P = .779), geographic origin (P = .171), and JIF (P = .531). CONCLUSION This scoping review provides information on 18 HEMS outcomes studies new to the evidence base in 2023.

Success with incrementally faster times to endovascular therapy (SWIFT-EVT): A systematic review and meta-analysis. J Stroke Cerebrovasc Dis 2024; 33:107964. [PMID: 39182706 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2024] [Revised: 08/18/2024] [Accepted: 08/21/2024] [Indexed: 08/27/2024] Open
Abstract
BACKGROUND A major systematic review and meta-analysis assessing trial data through 2014 (the Highly Effective Reperfusion Evaluated in Multiple Endovascular Stroke Trials, HERMES) demonstrated that particularly over the initial six hours of acute ischemic stroke (AIS), rapid performance of endovascular therapy (EVT) markedly improves outcomes. The current analysis, Success with Incrementally Faster Times to EVT (SWIFT-EVT), aimed to provide an updated metric summarizing latest estimates for modified Rankin Scale (mRS) improvements accrued by streamlining time to EVT. METHODS A systematic review and meta-analysis was conducted using electronic databases. Eligible studies reported a time-benefit slope with times from AIS onset (or time last known normal) to EVT commencement; the predictor was onset-to-groin (OTG) time. Primary and secondary outcomes were 90-day functional independence (mRS 0-2) and 90-day excellent function (mRS 0-1), respectively. RESULTS Five studies were included. Results showed increased change of good outcome with each hour of pre-EVT time savings for mRS 0-2 for 0-270' (OR 1.25, 95 % CI 1.16-1.35, I2 40 %) and 271-360' time frame (1.22, 95 % CI 1.12-1.33, I2 58 %). For the studies assessing mRS 0-1, estimates were found appropriate for both the 0-270' time frame (OR 1.34, 95 % CI 1.19-1.51, I2 27 %) and the 271-360' time frame (OR 1.20, 95 % CI 1.03-1.38, I2 60 %). CONCLUSIONS Each hour saved from AIS onset to EVT start is associated with a 22-25 % increased odds of achieving functional independence, a useful metric to inform patient-specific and systems planning decisions.

Is EGD Needed in all Patients after Suicidal or Exploratory Caustic Ingestions? J Med Toxicol 2024; 20:256-262. [PMID: 38647997 PMCID: PMC11288223 DOI: 10.1007/s13181-024-01003-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Revised: 02/22/2024] [Accepted: 02/29/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND Caustic ingestions are relatively uncommon, but remain a significant source of morbidity. Patients with caustic injury often undergo an urgent EGD, although it is not clear if an EGD is routinely needed in an asymptomatic patient. The study has two primary objectives; 1) to determine the utility of routine EGD in asymptomatic suicidal caustic ingestions; 2) to determine if asymptomatic unintentional acidic ingestions can be managed with observation alone, similar to basic ingestions. METHODS This retrospective study, which took place at 14 hospitals in three countries evaluated all patients who presented with a caustic ingestion between 2014-2020. The presence of symptoms and esophageal injury, demographic information, pH of ingested substance, reason for the ingestion, and outcome were recorded. RESULTS 409 patients were identified; 203 (46.9%) were male. The median (IQR) age was 18 (4-31) years; overall range 10 months to 78 years. Suicidal ingestions accounted for 155 (37.9%) of cases. Dysphagia or dysphonia were more likely in those with significant esophageal injury compared to those without (59.3% vs. 12.6% respectively; OR 10.1; 95% CI 4.43-23.1). Among 27 patients with significant esophageal injury, 48% were found in suicidal patients, compared with 51.9% in non-suicidal patients (p = NS). On multivariate regression, there was no difference in the rate of significant esophageal injury among suicidal vs. non suicidal patients (aOR 1.55; p = 0.45, 95% CI 0.45-5.33). Most ingestions involved basic substances (332/409; 81.2%). Unknown or mixed ingestions accounted for 25 (6.11%) of the ingestions. Significant esophageal burns were found in 6/52 (11.5%) of acid ingestions, compared with 21/332 (6.3%) of basic ingestions. Of the 42 cases of acidic ingestions without dysphagia or odynophagia, 2 (4.8%; 0.58-16.1%) had significant esophageal burns, compared with 9 (3.2%; 95% CI 1.4-5.9%) of the 284 basic ingestions; p = 0.64). On multivariate logistic regression, patients with acidic ingestions were not more likely to experience a significant burn (aOR 1.7; p = 0.11, 95% CI 0.9-3.1) compared to those with basic ingestions. No patient with significant esophageal burns was asymptomatic. CONCLUSION In this study, there was no statistical differences in the rates of significant burns between acidic and basic caustic ingestions. There were no significant esophageal injuries noted among asymptomatic patients.

Management Considerations for Air Medical Transport Programs Transfusing RhD-Positive Red Blood Cell-Containing Products to Females of Childbearing Potential. Air Med J 2024; 43:348-356. [PMID: 38897700 DOI: 10.1016/j.amj.2024.03.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 03/11/2024] [Accepted: 03/21/2024] [Indexed: 06/21/2024]
Abstract
Recent years have seen increased discussion surrounding the benefits of damage control resuscitation, prehospital transfusion (PHT) of blood products, and the use of whole blood over component therapy. Concurrent shortages of blood products with the desire to provide PHT during air medical transport have prompted reconsideration of the traditional approach of administering RhD-negative red cell-containing blood products first-line to females of childbearing potential (FCPs). Given that only 7% of the US population has blood type O negative and 38% has O positive, some programs may be limited to offering RhD-positive blood products to FCPs. Adopting the practice of giving RhD-positive blood products first-line to FCPs extends the benefits of PHT to such patients, but this practice does incur the risk of future hemolytic disease of the fetus and newborn (HDFN). Although the risk of future fetal mortality after an RhD-incompatible transfusion is estimated to be low in the setting of acute hemorrhage, the number of FCPs who are affected by this disease will increase as more air medical transport programs adopt this practice. The process of monitoring and managing HDFN can also be time intensive and costly regardless of the rates of fetal mortality. Air medical transport programs planning on performing PHT of RhD-positive red cell-containing products to FCPs should have a basic understanding of the pathophysiology, prevention, and management of hemolytic disease of the newborn before introducing this practice. Programs should additionally ensure there is a reliable process to notify receiving centers of potentially RhD-incompatible PHT because alloimmunization prophylaxis is time sensitive. Facilities receiving patients who have had PHT must be prepared to identify, counsel, and offer alloimmunization prophylaxis to these patients. This review aims to provide air medical transport professionals with an understanding of the pathophysiology and management of HDFN and provide a template for the early management of FCPs who have received an RhD-positive red cell-containing PHT. This review also covers the initial workup and long-term anticipatory guidance that receiving trauma centers must provide to FCPs who have received RhD-positive red cell-containing PHT.

Association of Non-Transfusion-Related Admission Hypocalcaemia With Haemodynamic Instability in Paediatric Major Trauma: A Retrospective Single-Centre Pilot Study. Cureus 2024; 16:e64983.

Abstract
Background The 'lethal triad' of acidosis, hypothermia, and coagulopathy is now considered a diamond of death, with ionised hypocalcaemia (iHypoCa) contributing to cardiovascular decompensation and coagulopathy. iHypoCa may be associated with haemodynamic instability and adverse outcomes in paediatric major trauma patients. However, current data are limited. The primary aim of this pilot study was to report the association between admission iHypoCa and early hypotension on admission in a cohort of paediatric major trauma patients. Secondary aims include reporting the incidence and differential determinants of iHypoCa and the association with treatment (vasoactive agents, blood transfusion, interventional radiology (IR), or surgery) and adverse outcomes (length of stay, morbidity (Glasgow Outcome Scale), and mortality). Methods This pilot study is a retrospective analysis of paediatric major trauma patients (<16 years old) admitted to a major trauma centre (2016-2022). Patients with an admission ionised calcium level obtained before the administration of blood products were included. Multivariable logistic regression was used to assess the dichotomous endpoint of hypotension (systolic blood pressure of <80 mmHg for <1 year, <85 mmHg for one to five years, <90 mmHg for five to 12 years, <100 mmHg for >12 years) for association with hypocalcaemia and adjusted for other potential variables of interest (age, gender, Injury Severity Score, pre-hospital fluids, and acidosis). Results Admission iHypoCa was observed in 8/45 (17.8% (95% confidence interval (CI) 9.3-31.3%)) patients. Other than the adolescent age group (p < 0.05), there were no significant differences in the baseline characteristics. As a pilot study, this was not powered for statistical significance; however, point estimates of the odds of hypotension were almost three times higher for patients with iHypoCa (odds ratio (OR) 2.8 (95% CI 0.4-23.6), p = 0.33). An association between iHypoCa and the need for IR/surgery in the first 24 hours of admission was also observed (OR 10.9 (95% CI 1.4-159.4), p < 0.05). Conclusion iHypoCa was observed in approximately one in six paediatric major trauma patients at admission and may be associated with increased odds of requiring IR/surgery. Larger multicentre studies are required to clarify point estimates for treatment requirements and adverse outcomes.

Abstract
Background Awake prone position (APP) has been reported to improve oxygenation in patients with COVID-19 disease and to reduce the requirement for invasive mechanical ventilation for patients requiring support with high flow nasal cannula. There is conflicting data for patients requiring lower-level oxygen support. Research question Does APP reduce escalation of oxygen support in COVID-19 patients requiring supplementary oxygen?The primary outcome was defined as an escalation of oxygen support from simple supplementary oxygen (NP, HM, NRB) to NIV (CPAP or BiPAP), HFNC or IMV; OR from NIV (CPAP or BiPAP) or HFNC to IMV by day30. Study design Two center, prospective, non-blind, randomised controlled trial. Patients with confirmed or suspected COVID-19 pneumonia requiring ≥ 5 liters/min oxygen to maintain saturations ≥ 94 % were randomised to either APP or control group. The APP group received a 3-h APP session three times per day for three days. Results Between 9 May and July 13, 2021, 89 adults were screened and 61 enrolled, 31 to awake prone position and 30 controls. There was no difference in the primary outcome, 7 (22.6 %) patients randomised to APP and 9 (30.0 %) controls required escalation of oxygen support (OR 0.68 (0.22-2.14), P = 0.51). There were no differences in any secondary outcomes, in APP did not improve oxygenation. Interpretation In COVID-19 patients, the use of APP did not prevent escalation of oxygen support from supplementary to invasive or non-invasive ventilation or improve patient respiratory physiology. Trial registration NCT04853979 (clinicaltrials.gov).

Abstract
BACKGROUND Based on convincing evidence for outcomes improvement in the military setting, the past decade has seen evaluation of prehospital transfusion (PHT) in the civilian emergency medical services (EMS) setting. Evidence synthesis has been challenging, due to study design variation with respect to both exposure (type of blood product administered) and outcome (endpoint definitions and timing). The goal of the current meta-analysis was to execute an overarching assessment of all civilian-arena randomized controlled trial (RCT) evidence focusing on administration of blood products compared to control of no blood products. METHOD The review structure followed the Cochrane group's Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). Using the Transfusion Evidence Library (transfusionevidencelibrary.com), the multidatabase (e.g. PubMed, EMBASE) Harvard On-Line Library Information System (HOLLIS), and GoogleScholar, we accessed many databases and gray literature sources. RCTs of PHT in the civilian setting with a comparison group receiving no blood products with 1-month mortality outcomes were identified. RESULTS In assessing a single patient-centered endpoint-1-month mortality-we calculated an overall risk ratio (RR) estimate. Analysis of three RCTs yielded a model with acceptable heterogeneity (I2 = 48%, Q-test p = 0.13). Pooled estimate revealed civilian PHT results in a statistically nonsignificant (p = 0.38) relative mortality reduction of 13% (RR 0.87, 95% CI 0.63-1.19). CONCLUSIONS Current evidence does not demonstrate 1-month mortality benefit of civilian-setting PHT. This should give pause to EMS systems considering adoption of civilian-setting PHT programs. Further studies should not only focus on which formulations of blood products might improve outcomes but also focus on which patients are most likely to benefit from any form of civilian-setting PHT.

Abstract
OBJECTIVES In adult major trauma patients admission hypocalcaemia occurs in approximately half of cases and is associated with increased mortality. However, data amongst paediatric patients are limited. The objectives of this review were to determine the incidence of admission ionised hypocalcaemia in paediatric major trauma patients and to explore whether hypocalcaemia is associated with adverse outcomes. METHODS A systematic review was conducted following PRISMA guidelines. All studies including major trauma patients <18 years old, with an ionised calcium concentration obtained in the Emergency Department (ED) prior to the receipt of blood products in the ED were included. The primary outcome was incidence of ionised hypocalcaemia. Random-effects Sidik-Jonkman modelling was executed for meta-analysis of mortality and pH difference between hypo- and normocalcaemia, Odds ratio (OR) was the reporting metric for mortality. The reporting metric for the continuous variable of pH difference was Glass' D (a standardized difference). Results are reported with 95% confidence intervals (CIs) and significance was defined as p <0.05. RESULTS Three retrospective cohort studies were included. Admission ionised hypocalcaemia definitions ranged from <1.00 mmol/l to <1.16 mmol/l with an overall incidence of 112/710 (15.8%). For mortality, modelling with low heterogeneity (I2 39%, Cochrane's Q p = 0.294) identified a non-significant (p = 0.122) estimate of hypocalcaemia increasing mortality (pooled OR 2.26, 95% CI 0.80-6.39). For the pH difference, meta-analysis supported generation of a pooled effect estimate (I2 57%, Cochrane's Q p = 0.100). The effect estimate of the mean pH difference was not significantly different from null (p = 0.657), with the estimated pH slightly lower in hypocalcaemia (Glass D standardized mean difference -0.08, 95% CI -0.43 to 0.27). CONCLUSION Admission ionised hypocalcaemia was present in at least one in six paediatric major trauma patients. Ionised hypocalcaemia was not identified to have a statistically significant association with mortality or pH difference.

Abstract
OBJECTIVES Stroke prevalence is progressively increasing in developing countries due to increased vascular risk factors. This study aims to describe the epidemiology, prevalent risk factors, and outcomes of stroke in a multi-ethnic society of Qatar. MATERIALS AND METHODS We conducted a retrospective analysis of all patients with suspected stroke admitted to stroke services between January 2014 and September 2020. RESULTS A total of 11,892 patients were admitted during this period with suspected stroke. Of these, the diagnosis was ischemic stroke (48.8 %), transient ischemic attack (10.3 %), intracerebral hemorrhage (10.9 %), cerebral venous sinus thrombosis (1.3 %), and stroke mimics (28.6 %). The median age was 52 (43-62), with a male-female ratio of 3:1. The study population was predominantly Asian (56.8 %) and Arab (36 %). The majority of the patients were hypertensive (66.8 %), diabetic (47.9 %), and dyslipidemic (45.9 %). A history of prior stroke was observed in 11.7 %, while 0.9 % had prior transient ischemic attack. Among ischemic strokes, 31.7 % arrived within 4.5 h, 12.5 % received thrombolysis, and 4.6 % underwent thrombectomy. Median Door-to-Needle time was 51 (33-72) minutes. The average length of stay was 5.2 ± 9.0 days, with 71.5 % discharged home, 13.8 % transferred to rehabilitation, 9.3 % to other specialties, 3 % to long-term care, and 2.4 % suffered in-hospital mortality. CONCLUSION Stroke in Qatar is characterized by a younger, expatriate-dominant cohort, with notable prevalence of ischemic and hemorrhagic stroke and a distinct risk factor profile. Further analysis of epidemiological differences among different population groups can inform targeted policies for prevention and management to reduce the burden of disease.

Abstract
OBJECTIVE Recent systematic reviews of acute care medicine applications of artificial intelligence (AI) have focused on hospital and general prehospital uses. The purpose of this scoping review was to identify and describe the literature on AI use with a focus on applications in helicopter emergency medical services (HEMS). METHODS A literature search was performed with specific inclusion and exclusion criteria. Articles were grouped by characteristics such as publication year and general subject matter with categoric and temporal trend analyses. RESULTS We identified 21 records focused on the use of AI in HEMS. These applications included both clinical and triage uses and nonclinical uses. The earliest study appeared in 2006, but over one third of the identified studies have been published in 2021 or later. The passage of time has seen an increased likelihood of HEMS AI studies focusing on nonclinical issues; for each year, the likelihood of a nonclinical focus had an odds ratio of 1.3. CONCLUSION This scoping review provides overview and hypothesis-generating information regarding AI applications specific to HEMS. HEMS AI may be ultimately deployed in nonclinical arenas as much as or more than for clinical decision support. Future studies will inform future decisions as to how AI may improve HEMS systems design, asset deployment, and clinical care.

Abstract
OBJECTIVE Helicopter emergency medical services (HEMS) is widely used for prehospital and interfacility transport, but there is a paucity of HEMS outcomes data from studies using randomized controlled trial designs. In the absence of robust randomized controlled trial evidence, judgments regarding HEMS potential benefit must be informed by observational data. Within the study design set of observational analyses, the natural experiment (NE) is notable for its high potential methodologic quality; NE designs are occasionally denoted "quasi-experimental." The aim of this study is to examine all NE outcomes studies in the HEMS literature and to discern what lessons can be learned from these potentially high-quality observational data. METHODS HEMS NE studies were identified during the development of a new HEMS Outcomes Assessment Research Database (HOARD). HOARD was constructed using a broad-ranging search of published and gray literature resources (eg, PubMed, Embase, and Google Scholar) that used variations of the terms "helicopter EMS," "air ambulance," and "air medical transport." Among the 221 studies ultimately included in HOARD, 16 NE publications describing 13 sets of observational data comprising myriad diagnostic groups were identified. Of these 16 HEMS NEs, 4 HEMS NE studies assessing trauma outcomes were used in a meta-analysis. A meta-analysis was also performed of 4 HEMS NE studies. RESULTS Although the disparity of studies (in terms of both case mix and end points) precluded the generation of a pooled effect estimate of an adjusted mortality benefit of HEMs versus ground emergency medical services, HEMS was found to be associated with outcomes improvement in 8 of the 13 cohorts. CONCLUSION The weight of the NE evidence supports a conclusion of some form of HEMS-mediated outcomes improvement in a variety of patient types. Meta-analysis of 4 HEMS NE studies assessing trauma outcomes generated a model with acceptable heterogeneity (I2 = 43%, Q test: P = .16), which significantly (P < .01) favored HEMS use with a pooled HEMS survival odd ratio estimate of 1.66 (95% confidence interval, 1.23-2.22).

Abstract
BACKGROUND & AIMS Deployment of law enforcement operational canines (OpK9s) risks injuries to the animals. This study's aim was to assess the current status of states' OpK9 (veterinary Emergency Medical Services [VEMS]) laws and care protocols within the United States. METHODS Cross-sectional standardized review of state laws/regulations and OpK9 VEMS treatment protocols was undertaken. For each state and for the District of Columbia (DC), the presence of OpK9 legislation and/or care protocols was ascertained. Information was obtained through governmental records and from stakeholders (eg, state EMS medical directors and state veterinary boards).The main endpoints were proportions of states with OpK9 laws and/or treatment protocols. Proportions are reported with 95% confidence intervals (CIs). Fisher's exact test (P <.05) assessed whether presence of an OpK9 law in a given jurisdiction was associated with presence of an OpK9 care protocol, and whether there was geographic variation (based on United States Census Bureau regions) in presence of OpK9 laws or protocols. RESULTS Of 51 jurisdictions, 20 (39.2%) had OpK9 legislation and 23 (45.1%) had state-wide protocols for EMS treatment of OpK9s. There was no association (P = .991) between presence of legislation and presence of protocols. There was no association (P = .144) between presence of legislation and region: Northeast 66.7% (95% CI, 29.9-92.5%), Midwest 50.0% (95% CI, 21.1-78.9%), South 29.4% (95% CI, 10.3-56.0%), and West 23.1% (95% CI, 5.0-53.8%). There was significant (P = .001) regional variation in presence of state-wide OpK9 treatment protocols: Northeast 100.0% (95% CI, 66.4-100.0%), Midwest 16.7% (95% CI, 2.1-48.4%), South 47.1% (95% CI, 23.0-72.2%), and West 30.8% (95% CI, 9.1-61.4%). CONCLUSION There is substantial disparity with regard to presence of OpK9 legal and/or clinical guidance. National collaborative guidelines development is advisable to optimize and standardize care of OpK9s. Additional attention should be paid to educational and training programs to best utilize the limited available training budgets.

Abstract
In the United States, there are approximately 750,000 ST-elevation myocardial infarction cases each year. Streamlined care and rapid delivery for primary percutaneous coronary intervention (PPCI) is associated with improved survival. This systematic review and meta-analysis aimed to generate a practical estimate of mortality savings for every notional 30-minute decrease in the time to achieving PPCI. Included studies were those that provided a specific absolute risk reduction for a specific reduction in pre-PPCI time. The eligible studies evaluated the survival benefit from pre-PPCI time savings measured in any interval ending with PPCI and commencing with objectively recorded timing, such as initial emergency call, first medical contact, or hospital arrival. Study planning called for the reporting of data as individual study results, with a pooled effect estimate of relative risk calculated with random-effects meta-analysis. A total of 1,088 records were eligible for review; 52 were reviewed in full text, with 4 studies (total patient n = 235,814, overall mortality 4.7% to 7.8%) included in the final analysis. All 4 studies reported significant time-related survival benefit over the study focus window of 60 to 180 minutes pre-PPCI. The number of lives saved per 100 cases for each 30-minute pre-PPCI time savings ranged from 0.8 to 1.9. The overall effect estimate generated was 0.753 (95% confidence interval 0.712 to 0.796), with acceptable heterogeneity (I2 = 36%). In conclusion, a pooled effect calculation estimated a 24.7% relative risk reduction for each 30 minutes of time savings. For cases that underwent PPCI within 60 to 180 minutes of initial presentation with known baseline mortality risk, the time savings in 30-minute epochs can be leveraged to estimate a specific number of lives saved; this may be useful for those involved in the organization of medical care who make systemwide plans and individual patient triage decisions.

Abstract
OBJECTIVES This study interviewed adult patients presenting to the emergency department (ED) for various pain conditions enquiring about their preferred tool for reporting pain severity and preferred time interval between initial assessment and subsequent pain reassessments. METHODS A prospective observational (cross-sectional) study was conducted in adult patients with acute pain in a tertiary care hospital ED setting. Patients' initial pain score was recorded using NRS (numerical rating scale) pain scale, and appropriate analgesia offered. Once the patient had been evaluated by an attending physician, a research team member interviewed the patient regarding the pain reassessment time and preferred pain assessment tool. The pain assessment tools evaluated in this study were NRS, PS (picture scale or face pain scale), VRS (verbal rating scale), and VAS (visual analogue scale). The patients were presented with the four pain assessment tools (in their primary language) through an audio-visual on an electronic tablet display. RESULTS 200 (138 male, mean age 36.5 ± 11.17) patients participated in the study. With increasing age, pain reassessment interval increased by 0.19 min (95% CI 0.03-0.36 min). Males requested pain reassessment 6.7 min (95% CI 2.2-10.8) faster than females. In this study, the preferred interval for pain reassessment was reported as a mean of 22.8 (SD + -13.6) minutes. There was no relationship reported between time reassessment and pain severity (P = 0.22). Out of 200 subjects, irrespective of the initial pain scores, 100 preferred NRS. NRS was preferred by patients with mild to moderated pain due to the perception of being faster. However, patients with severe pain choose a non-NRS scale to prioritize accuracy. CONCLUSION There was no influence found between the initial pain severity scores and the desired frequency of pain reassessment. However, associations were identified between the time for pain reassessment interval and age, sex, and geographical region. Patients with severe pain preferred PS or VRS while patients with mild/moderate pain preferred the NRS.

Abstract
OBJECTIVE Helicopter emergency medical services (HEMS) literature has been assessed in reviews focusing on various diagnoses, but there are few, if any, summaries of the entire body of HEMS outcomes evidence. Our goal was to summarize the existing research addressing patient-centered outcomes potentially accrued with HEMS. METHODS As part of the Critical Care Transport Collaborative Outcomes Research Effort, we generated the HEMS Outcomes Assessment Research Database and executed descriptive analyses of longitudinal trends from 1983 to 2022. Both indexed and gray literature sources were incorporated in the HEMS Outcomes Assessment Research Database. Studies were reviewed by at least 2 authors to select those that addressed a patient-centered outcome. Studies addressing solely HEMS logistics were excluded. Categoric analyses were executed with the Fisher exact test, and continuous variables were evaluated for normality with normal quantile plotting and a comparison of medians and 95% confidence intervals. RESULTS We found that HEMS outcomes study sample sizes increased steadily from 1983 to 2012, with the most recent decade demonstrating a marked increase in the rate of publication of HEMS outcomes studies. Most research (70.6%) addressed trauma patient outcomes, but recent decades have seen a significant increase in non-trauma studies. Recent decades have also been characterized by an increase in the production of HEMS outcomes research outside of North America and Europe. CONCLUSION This study summarizes the current state of the HEMS outcome literature. We highlight increasing contributions from worldwide researchers and increasing focus on HEMS benefits in non-trauma cases, particularly time-critical cases such as cardiac or stroke diagnoses. This provides a basis for further investigations into patient-oriented benefits potentially accrued with HEMS.

Abstract
BACKGROUND AND AIM Helicopter EMS (HEMS) is a well-established mode of rapid transportation for patients with need for time-sensitive interventions, especially in patients with significant traumatic injuries. Traditionally in the setting of trauma, HEMS is often considered appropriate when used for patients with "severe" injury as defined by Injury Severity Score (ISS) >15. This may be overly conservative, and patients with a lower ISS may benefit from HEMS-associated speed or care quality. Our objective was to perform a meta-analysis of trauma HEMS transports to evaluate for possible mortality benefit in injured cases defined by an ISS score >8, lower than the customary ISS cutoff of >15. METHODS A broad search of the literature was performed including PubMed, EMBASE, SCOPUS, Cochrane Central Register of Controlled Trials, and Google Scholar from the years 1970 to 2022. The gray literature and reference lists of included publications were also examined. We included studies with the outcome of mortality in HEMS vs control in trauma transports from scene of injury for patients (adult or pediatric) with ISS > 8. RESULTS Nine eligible studies were used in the final analysis: six in the primary analysis and three in sensitivity analysis due to patient overlap. All studies reported statistically significant survival benefit in HEMS compared to control group. The minimum survival odds ratio (OR) benefit observed was OR 1.15 (95% CI 1.06-1.25) and maximum was OR 2.04 (95% CI 1.18-3.57). Risk of bias tool (ROBINS-I) application yielded moderate to low risk of bias, mainly due to the observational nature of the studies included. CONCLUSIONS There was a statistically significant survival benefit in patients with ISS > 8 when HEMS was used over traditional ground ambulance transportation, although novel and more inclusive trauma triage criteria may be more appropriate in the future to guide HEMS utilization decision-making. Restricting HEMS to trauma patients with ISS >15 likely misses survival benefit that could be afforded to the subset of trauma patients with serious injury.

Abstract
OBJECTIVE Paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs) and opiates/opioids, administered parenterally via intravenous or intramuscular route, are widely used to provide analgesia for patients with moderate to severe pain. This systematic review and meta-analysis evaluated the level of analgesia provided by intravenous paracetamol (IVP) alone compared with NSAIDs (intravenous or intramuscular), or opioids (intravenous) alone in adults attending the ED with acute pain. METHODS Two authors independently searched PubMed (MEDLINE), Web of Science, Embase (OVID), Cochrane Library, SCOPUS and Google Scholar (3 March 2021-20 May 2022) for randomised trials without any language or date restriction. Clinical trials were evaluated using the Risk of Bias V.2 tool. The primary outcome was mean difference (MD) for pain reduction at 30 min (T30) post analgesia delivery. The secondary outcomes were MD in pain reduction at 60, 90 and 120 min; the need for rescue analgesia; and the occurrence of adverse events (AEs). RESULTS Twenty-seven trials (5427 patients) were included in the systematic review and 25 trials (5006 patients) in the meta-analysis. There was no significant difference in pain reduction at T30 between the IVP group and opioids (MD -0.13, 95% CI -1.49 to 1.22) or IVP and NSAIDs (MD -0.27, 95% CI -1.0 to 1.54. There was also no difference at 60 min, IVP group versus opioid group (MD -0.09, 95% CI -2.69 to 2.52) or IVP versus NSAIDs (MD 0.51, 95% CI 0.11 to 0.91). The quality of the evidence using Grading of Recommendations, Assessments, Development and Evaluations methodology was low for MD in pain scores.The need for rescue analgesia at T30 was significantly higher in the IVP group compared with the NSAID group (risk ratio (RR): 1.50, 95% CI 1.23 to 1.83), with no difference found between the IVP group and the opioid group (RR: 1.07, 95% CI 0.67 to 1.70). AEs were 50% lower in the IVP group compared with the opioid group (RR: 0.50, 95% CI 0.40 to 0.62), whereas no difference was observed in the IVP group compared with the NSAID group (RR: 1.30, 95% CI 0.78 to 2.15). CONCLUSION In patients presenting to the ED with a diverse range of pain conditions, IVP provides similar levels of pain relief compared with opiates/opioids or NSAIDs at T30 post administration. Patients treated with NSAIDs had lower risk of rescue analgesia, and opioids cause more AEs, suggesting NSAIDs as the first-choice analgesia and IVP as a suitable alternative.

Abstract
Background and importance Each year, 1.4 million patients attend a UK ED with a head injury. Mild traumatic brain injury affects up to 300/100 000 admitted patients/year and a greater number of non-admitted patients. Identifying those patients with a head injury that have concussion, and of those, which will have a prolonged recovery, is critical for discharge planning. The Vestibular/Ocular Motor Screening test (VOMS) has been reported as a useful “sideline tool” to evaluate for sports-related concussion (SRC). VOMS has been assessed for utility primarily for predicting in head-injured, which cases will have concussion, and secondarily in predicting in concussed patients, which will have prolonged recovery. Originally described in 2014, VOMS has not been subject to systematic review or meta-analysis, with regard to its predictive performance for concussion. Objective To assess the state of VOMS evidence for dichotomously classifying concussion status in patients with non-severe head injury Design Systematic review. Setting and participants Studies comprising the review enrolled ambulatory head-injured adults and children, usually from sports-related settings, in Europe or the USA. Exposure VOMS. Outcome measures Presence of concussion, presence of prolonged recovery in concussed patients Main results The review identified 17 studies, characterized by a wide variety of specific approaches to administering and scoring VOMS. While VOMS showed promise as a screening tool for concussion, marked study heterogeneity precluded generation of a pooled effect estimate for VOMS performance. Conclusion VOMS is potentially useful as a concussion screening tool. Available evidence from the SRC arena suggests sensitivity ranging from 58–96%, with specificity 46−92%. Directions for future VOMS research should include evaluation of standardized administration and scoring, potentially of a simpler VOMS (with fewer components), in a general head-injured population. Further analysis of precisely defined VOMS application may be useful to determine the proper place of VOMS screening for the head-injured.
