A Shorter Door-In-Door-Out Time Is Associated with Improved Outcome in Large Vessel Occlusion Stroke.

Introduction: Endovascular thrombectomy (EVT) significantly improves outcomes in large vessel occlusion stroke (LVOS). When a patient with a LVOS arrives at a hospital that does not perform EVT, emergent transfer to an endovascular stroke center (ESC) is required. Our objective was to determine the association between door-in-door-out time (DIDO) and 90-day outcomes in patients undergoing EVT. Methods: We conducted an analysis of the Optimizing Prehospital Stroke Systems of Care-Reacting to Changing Paradigms (OPUS-REACH) registry of 2,400 LVOS patients treated at nine ESCs in the United States. We examined the association between DIDO times and 90-day outcomes as measured by the modified Rankin scale. Results: A total of 435 patients were included in the final analysis. The mean DIDO time for patients with good outcomes was 17 minute shorter than patients with poor outcomes (122 minutes [min] vs 139 min, P = 0.04). Absolute DIDO cutoff times of ≤60 min, ≤90 min, or ≤120 min were not associated with improved functional outcomes (46.4 vs 32.3%, P = 0.12; 38.6 vs 30.6%, P = 0.10; and 36.4 vs 28.9%, P = 0.10, respectively). This held true for patients with hyperacute strokes of less than four-hour onset. Lower baseline National Institutes of Health Stroke Scale (NIHSS) score (11.9 vs 18.2, P = <.001) and younger age (62.5 vs 74.9 years (P < .001) were associated with improved outcomes. On multiple regression analysis, age (odds ratio [OR] 1.71, 95% confidence interval [CI] 1.45-2.02) and baseline NIHSS score (OR 1.67, 95% CI 1.42-1.98) were associated with improved outcomes while DIDO time was not associated with better outcome (OR 1.13, 95% CI 0.99-1.30). Conclusion: Although the DIDO time was shorter for patients with a good outcome, this was non-significant in multiple regression analysis. Receipt of intravenous thrombolysis and time to EVT were not associated with better outcomes, while male gender, lower age, arrival by private vehicle, and lower NIHSS score portended better outcomes. No absolute DIDO-time cutoff or modifiable factor was associated with improved outcomes for LVOS. This study underscores the need to streamline DIDO times but not to set an artificial DIDO time benchmark to meet.

Transport Rates and Prehospital Intervals for an EMS Telemedicine Intervention.

INTRODUCTION: Emergency medical services (EMS) facilitated telemedicine encounters have been proposed as a strategy to reduce transports to hospitals for patients who access the 9-1-1 system. It is unclear which patient impressions are most likely able to be treated in place. It is also unknown if the increased time spent facilitating the telemedicine encounter is offset by the time saved from reducing the need for transport. The objective of this study was to determine the association between the impressions of EMS clinicians of the patients' primary problems and transport avoidance, and to describe the effects of telemedicine encounters on prehospital intervals. METHODS: This was a retrospective review of EMS records from two commercial EMS agencies in New York and Tennessee. For each EMS call where a telemedicine encounter occurred, a matched pair was identified. Clinicians' impressions were mapped to the corresponding category in the International Classification of Primary Care, 2nd edition (ICPC-2). Incidence and rates of transport avoidance for each category were determined. Prehospital interval was calculated as the difference between the time of ambulance dispatch and back-in-service time. RESULTS: Of the 463 prehospital telemedicine evaluations performed from March 2021 to April 2022, 312 (67%) avoided transports to the hospital. Respiratory calls were most likely to result in transport avoidance (p = 0.018); no other categories had statistically significant transport rates. Four hundred sixty-one (99.6%) had matched pairs identified and were included in the analysis. When compared to the matched pair, telemedicine without transport was associated with a prehospital interval reduction in 68% of the cases with a median reduction of 16 min; this is significantly higher than telemedicine with transport when compared to the matched pair with a median interval increase in 27 min. Regardless of transport status, the prehospital interval was a median of 4 min shorter for telemedicine encounters than non-telemedicine encounters (p = 0.08). CONCLUSION: In this study, most telemedicine evaluations resulted in ED transport avoidance, particularly for respiratory issues. Telemedicine interventions were associated with a median four-minute decrease in prehospital interval per call. Future research should investigate the long-term effects of telemedicine on patient outcomes.

Factors associated with door-in-door-out times in large vessel occlusion stroke patients undergoing endovascular therapy.

INTRODUCTION: In the management of large vessel occlusion stroke (LVOS), patients are frequently evaluated first at a non-endovascular stroke center and later transferred to an endovascular stroke center (ESC) for endovascular treatment (EVT). The door-in-door-out time (DIDO) is frequently used as a benchmark for transferring hospitals though there is no universally accepted nor evidenced-based DIDO time. The goal of this study was to identify factors affecting DIDO times in LVOS patients who ultimately underwent EVT. METHODS: The Optimizing Prehospital Use of Stroke Systems of Care-Reacting to Changing Paradigms (OPUS-REACH) registry is comprised of all LVOS patients who underwent EVT at one of nine endovascular centers in the Northeast United States between 2015 and 2020. We queried the registry for all patients who were transferred from a non-ESC to one of the nine ESCs for EVT. Univariate analysis was performed using t-tests to obtain a p value. A priori, we defined a p value of <0.05 as significant. Multiple logistic regression was conducted to determine the association of variables to estimate an odds ratio. RESULTS: 511 patients were included in the final analysis. The mean DIDO times for all patients was 137.8 min. Vascular imaging and treatment at a non-certified stroke center were associated with longer DIDO times by 23 and 14 min, respectively. On multivariate analyses, the acquisition of vascular imaging was associated with 16 additional minutes spent at the non-ESC while presentation to a non-stroke certified hospital was associated with 20 additional minutes spent at the transferring hospital. The administration of intravenous thrombolysis (IVT) was associated with 15 min less spent at the non-ESC. DISCUSSION: Vascular imaging and non-stroke certified stroke centers were associated with longer DIDO times. Non-ESCs should integrate vascular imaging into their workflow as feasible to reduce DIDO times. Further work examining other details regarding the transfer process such as transfer via ground or air, could help further identify opportunities to improve DIDO times.

Evolution of endovascular stroke centers and disparities in access to stroke care in four Northeastern states: 2015-2019.

OBJECTIVES: Disparities exist throughout our healthcare system, especially related to access to care. Advanced stroke care for strokes is only available at selected endovascular centers (ESCs) in the United States. Although the number of ESCs increase each year, this does not necessarily reflect increased access to care. Here, we look at the evolution of ESC in four states and disparities in access to advanced stroke care. MATERIALS AND METHODS: This is a descriptive study of access to ESCs in four Northeastern states between 2015-2019. Using data from the United States Census Bureau and spatial analysis, we examined the proportion of the population with drive times of less than 60 minutes stratified by income, race/ethnicity, population density, and insurance. We also calculated the mean drive time for each of these socioeconomic groups from their census tracts to the nearest ESC. RESULTS: Between 2015 and 2019, the number of ESCs increased from 15 to 48. The proportion of patients within a 60-minute drive of an ESC increased from 77% to 88%. However, only 66% of the least densely populated quartile lived within 60 min of an ESC. By income, access to ESCs in the wealthiest quartile was 96.6% compared to 83.7% in the lowest quartile. Hispanics and non-Hispanic Blacks had the largest proportions of populations within 60 minutes of an ESC while Non-Hispanic Whites had the smallest. CONCLUSIONS: This study underscores the need to evaluate the placement of new ESCs to assure that these hospitals decrease disparities and increase access to advanced stroke care.

Are Pediatric Manual Resuscitators Only Fit for Pediatric Use? A Comparison of Ventilation Volumes in a Moving Ambulance.

Background: The manual resuscitator device is the most common method of ventilating patients with respiratory failure, either with a facemask, or with an advanced airway such as an endotracheal tube (ETT). Barotrauma and gastric inflation from excessive ventilation volumes or pressure are concerning complications. Ventilating adult patients with pediatric manual resuscitator may provide more lung-protective tidal volumes based on stationary patient simulations. However, use of a pediatric manual resuscitator in mobile simulations contradictorily generates inadequate tidal volumes.Methods: Sixty-two emergency medical services (EMS) clinicians in a moving ambulance ventilated a manikin using pediatric and adult manual resuscitators in conjunction with oral-pharyngeal airway, i-gel, King LTS-D, or an endotracheal tube.Results: Oral-pharyngeal airway data were discarded due to EMS clinician inability to produce measurable tidal volumes. Mean ventilation volumes using the pediatric manual resuscitator were inadequate compared to those with the adult manual resuscitator on all other airway devices. In addition, i-gel, King LTS-D, and endotracheal tube volumes were statistically comparable. Paramedics ventilated larger volumes than emergency medical technicians.Conclusions: Using a pediatric manual resuscitator on adult patients is not supported by our findings.

Optimizing Prehospital Stroke Systems of Care-Reacting to Changing Paradigms (OPUS-REACH): a pragmatic registry of large vessel occlusion stroke patients to create evidence-based stroke systems of care and eliminate disparities in access to stroke care.

BACKGROUND: Large vessel occlusion (LVO) strokes are best treated with rapid endovascular therapy (EVT). There are two routes that LVO stroke patients can take to EVT therapy when transported by EMS: primary transport (ambulance transports directly to an endovascular stroke center (ESC) or secondary transport (EMS transports to a non-ESC then transfers for EVT). There is no clear evidence which path to care results in better functional outcomes for LVO stroke patients. To find this answer, an analysis of a large, real-world population of LVO stroke patients must be performed. METHODS: A pragmatic registry of LVO stroke patients from nine health systems across the United States. The nine health systems span urban and rural populations as well as the spectrum of socioeconomic statuses. We will use univariate and multivariate analysis to explore the relationships between type of EMS transport, socioeconomic factors, and LVO stroke outcomes. We will use geographic information systems and spatial analysis to examine the complex movements of patients in time and space. To detect an 8% difference between groups, with a 3:1 patient ratio of primary to secondary transports, 95% confidence and 80% power, we will need approximately 1600 patients. The primary outcome is the patients with modified Rankin Scale (mRS) ≤ 2 at 90 days. Subgroup analyses include patients who receive intravenous thrombolysis and duration of stroke systems. Secondary analyses include socioeconomic factors associated with poor outcomes after LVO stroke. DISCUSSION: Using the data obtained from the OPUS-REACH registry, we will develop evidence based algorithms for prehospital transport of LVO stroke patients. Unlike prior research, the OPUS-REACH registry contains patient-level data spanning from EMS dispatch to ninety day functional outcomes. We expect that we will find modifiable factors and socioeconomic disparities associated with poor outcomes in LVO stroke. OPUS-REACH with its breadth of locations, detailed patient records, and multidisciplinary researchers will design the optimal prehospital stroke system of care for LVO stroke patients.

Fungal Rhino-orbital Cerebritis in a Patient with Steroid-induced Ketoacidosis.

Fungal rhino-orbital cerebritis is a devastating opportunistic invasive disease. Survival requires urgent diagnosis. Thus, all patients at risk who present with rhinosinusitis-type symptoms and have co-morbid conditions that decrease their immunocompetence should trigger the clinician's consideration of this disease. Treatment includes antifungals and emergent surgical debridement.

Intravenous vs. intraosseous access and return of spontaneous circulation during out of hospital cardiac arrest.

INTRODUCTION: Guidelines endorse intravenous (IV) and intraosseous (IO) medication administration for cardiac arrest treatment. Limited clinical evidence supports this recommendation. A multiagency, retrospective study was performed to determine the association between parenteral access type and return of spontaneous circulation (ROSC) in out of hospital cardiac arrest. METHODS: This was a structured, retrospective chart review of emergency medical services (EMS) records from three agencies. Data was analyzed from adults who suffered OHCA and received epinephrine through EMS established IV or IO access during the 18-month study period. Per regional EMS protocols, choice of parenteral access type was at the provider's discretion. Non-inferiority analysis was performed comparing the association between first access type attempted and ROSC at time of emergency department arrival. RESULTS: 1310 subjects met inclusion criteria and were included in the analysis. Providers first attempted parenteral access via IV route in 788 (60.15%) subjects. Providers first attempted parenteral access via IO route in 552 (39.85%) subjects. Rates of ROSC at time of ED arrival were 19.67% when IV access was attempted first and 19.92% when IO access was attempted first. An IO first approach was non-inferior to an IV first approach based on the primary end point ROSC at time of emergency department arrival (p=0.01). CONCLUSION: An IO first approach was non-inferior to an IV first approach based on the end point ROSC at time of emergency department arrival.

Association between EMS Question Bank Completion and Passing Rates on the EMS Certification Examination.

INTRODUCTION: A board review question bank was created to assist candidates in their preparation for the 2015 EMS certification examination. We aimed to describe the development of this question bank and evaluate its successes in preparing candidates to obtain EMS subspecialty board certification. METHODS: An online question bank was developed by 13 subject matter experts who participated as item writers, representing eight different EMS fellowship programs. The online question bank consisted of four practice tests, with each of the tests comprised of 100 questions. The number of candidates who participated in and completed the question bank was calculated. The passing rate among candidates who completed the question bank was calculated and compared to the publicly reported statistics for all candidates. The relationship between candidates' performance on the question bank and subspecialty exam pass rates was determined. RESULTS: A total of 252 candidates took at least one practice test and, of those, 225 candidates completed all four 100-question practice tests. The pass rate on the 2015 EMS certification exam was 79% (95%CI 74-85%) among candidates who completed the question bank, which is 12% higher than the overall pass rate (p = 0.003). Candidates' performance on the question bank was positively associated with overall success on the exam (X2 = 75.8, p < 0.0001). Achieving a score of ≥ 70% on the question bank was associated with a higher likelihood of passing the exam (OR = 17.8; 95% CI: 8.0-39.6). CONCLUSION: Completing the question bank program was associated with improved pass rates on the EMS certification exam. Strong performance on the question bank correlated with success on the exam.

Adherence to Follow-Up Recommendations by Triathlon Competitors Receiving Event Medical Care.

Introduction. We sought to investigate triathlete adherence to recommendations for follow-up for participants who received event medical care. Methods. Participants of the 2011 Ironman Syracuse 70.3 (Syracuse, NY) who sought evaluation and care at the designated finish line medical tent were contacted by telephone approximately 3 months after the initial encounter to measure adherence with the recommendation to seek follow-up care after event. Results. Out of 750 race participants, 35 (4.6%) athletes received event medical care. Of these 35, twenty-eight (28/35; 80%) consented to participate in the study and 17 (61%) were available on telephone follow-up. Of these 17 athletes, 11 (11/17; 65%) of participants reported that they had not followed up with a medical professional since the race. Only 5 (5/17; 29%) confirmed that they had seen a medical provider in some fashion since the race; of these, only 2 (2/17; 12%) sought formal medical follow-up resulting from the recommendation whereas the remaining athletes merely saw their medical providers coincidentally or as part of routine care. Conclusion. Only 2 (2/17; 12%) of athletes who received event medical care obtained postrace follow-up within a one-month time period following the race. Event medical care providers must be aware of potential nonadherence to follow-up recommendations.

Mandatory Rest Stops Improve Athlete Safety during Event Medical Coverage for Ultramarathons.

INTRODUCTION: Provisions of medical direction and clinical services for ultramarathons require specific attention to heat illness. Heat stress can affect athlete performance negatively, and heat accumulation without acclimatization is associated with the development of exertional heat stroke (EHS). In order to potentially mitigate the risk of this safety concern, the Jungle Marathon (Para, Brazil) instituted mandatory rest periods during the first two days of this 7-day, staged, Brazilian ultramarathon. METHODS: Race records were reviewed retrospectively to determine the number of runners that suffered an emergency medical complication related to heat stress and did not finish (DNF) the race. Review of records included three years before and three years after the institution of these mandatory rest periods. RESULTS: A total of 326 runners competed in the Jungle Marathon during the 2008-2013 period of study. During the pre-intervention years, a total of 46 athletes (21%) DNF the full race with 25 (54.3%) cases attributed to heat-related factors. During the post-intervention years, a total of 26 athletes (24.3%) DNF the full race with four (15.4%) cases attributed to heat-related factors. CONCLUSION: Mandatory rest stops during extreme running events in hot or tropical environments, like the Jungle Marathon, are likely to improve athlete safety and improve the heat acclimatization process.

Endotracheal intubation with a video-assisted semi-rigid fiberoptic stylet by prehospital providers.

BACKGROUND: Emergency medical technicians intubate patients in unfamiliar surroundings and with less than ideal positioning. This study was designed to evaluate advanced life support (ALS) emergency medical technicians' (EMTs) ability to successfully intubate a simulated airway using a video-assisted semi-rigid fiberoptic stylet, the Clarus Video System (CVS). METHODS: ALS EMTs were first shown a brief slideshow and three example videos and then given 20 min to practice intubating a mannequin using both the CVS and standard direct laryngoscopy (DL). The mannequin was then placed on the floor to simulate field intubation at the scene. Each participant was given up to three timed attempts with each technique. Endotracheal tube position was confirmed with visualization by one of the study authors. Comparisons and statistical analysis were conducted using SPSS® Statistics 21 (IBM®). Demographics and survey results were also collected and analyzed. RESULTS: The median total time for intubation was 15.00 s for DL and 15.50 s for CVS revealing no significant difference between the two techniques (p = 0.425), and there was no significant difference in the number of attempts required to successfully place the endotracheal tube (ETT) (p = 0.997). Demographic factors including handedness and eye dominance did not seem to affect outcomes. Participants reported a relatively high level of satisfaction with the CVS. CONCLUSIONS: ALS EMTs were able to obtain intubation results similar to those of their usual direct laryngoscopy technique when utilizing a video-assisted semi-rigid fiberoptic stylet with very limited instruction and experience with the device. The CVS technique warrants further study for use as an alternative to DL and video laryngoscopy in the prehospital difficult airway scenario.

A prospective evaluation of the contribution of ambient temperatures and transport times on infrared thermometry readings of intravenous fluids utilized in EMS patients.

BACKGROUND: During cold weather months in much of the country, the temperatures in which prehospital care is delivered creates the potential for inadvertently cool intravenous fluids to be administered to patients during their transport and care by emergency medical services (EMS). There is some potential for patient harm from unintentional infusion of cool intravenous fluids. Prehospital providers in these cold weather environments are likely using fluids that are well below room temperature when prehospital intravenous fluid (IVF) warming techniques are not being employed. It was hypothesized that cold ambient temperatures during winter months in the study location would lead to the inadvertent infusion of cold intravenous fluids during prehospital patient care. METHODS: Trained student research assistants obtained three sequential temperature measurements using an infrared thermometer in a convenience sample of intravenous fluid bags connected to patients arriving via EMS during two consecutive winter seasons (2011 to 2013) at our receiving hospital in Syracuse, New York. Intravenous fluids contained in anything other than a standard polyvinyl chloride bag were not measured and were not included in the study. Outdoor temperature was collected by referencing National Weather Service online data at the time of arrival. Official transport times from the scene to the emergency department (ED) and other demographic data was collected from the EMS provider or their patient care record at the time of EMS interaction. RESULTS: Twenty-three intravenous fluid bag temperatures were collected and analyzed. Outdoor temperature was significantly related to the temperature of the intravenous fluid being administered, b = 0.69, t(21) = 4.3, p < 0.001. Transport time did not predict the measured intravenous fluid temperatures, b = 0.12, t(20) = 0.55, p < 0.6. CONCLUSIONS: Use of unwarmed intravenous fluid in the prehospital environment during times of cold ambient temperatures can lead to the infusion of cool intravenous fluid and may result in harm to patients. Short transport times do not limit this risk. Emergency departments should not rely on EMS agencies' use of intravenous fluid warming techniques and should consider replacing EMS intravenous fluids upon ED arrival to ensure patient safety.

Backboard time for patients receiving spinal immobilization by emergency medical services.

BACKGROUND: Use of backboards as part of routine trauma care has recently come into question because of the lack of data to support their effectiveness. Multiple authors have noted the potential harm associated with backboard use, including iatrogenic pain, skin ulceration, increased use of radiographic studies, aspiration and respiratory compromise. An observational study was performed at a level 1 academic trauma center to determine the total and interval backboard times for patients arriving via emergency medical services (EMS). FINDINGS: Patients were directly observed. Transport time was recorded as an estimate of initiation of backboard use; arrival time, nurse report time and time of removal from the backboard were all recorded. National Emergency Department Overcrowding Study (NEDOCS) score, Emergency Severity Index (ESI) and demographic information were recorded for each patient encounter. Forty-six patients were followed. The mean total backboard time was 54 min (SD ±65). The mean EMS interval was 33 min (SD ±64), and the mean ED interval was 21 min (SD ±15). The ED backboard interval trended inversely to ESI (1 = 5 min, 2 = 10 min, 3 = 25 min, 4 = 26 min, 5 = 32 min). CONCLUSION: Patients had a mean total backboard time of around an hour. The mean EMS interval was greater than the mean ED interval. Further study with a larger sample directed to establishing associated factors and to target possible reduction strategies is warranted.

Evaluation of ambulance offload delay at a university hospital emergency department.

BACKGROUND: Ambulance offload delay (AOD) has been recognized by the National Association of EMS Physicians (NAEMSP) as an important quality marker. AOD is the time between arrival of a patient by EMS and the time that the EMS crew has given report and moved the patient off of the EMS stretcher, allowing the EMS crew to begin the process of returning to service. The AOD represents a potential delay in patient care and a delay in the availability of an EMS crew and their ambulance for response to emergencies. This pilot study was designed to assess the AOD at a university hospital utilizing direct observation by trained research assistants. FINDINGS: A convenience sample of 483 patients was observed during a 12-month period. Data were analyzed to determine the AOD overall and for four groups of National Emergency Department Overcrowding Scale (NEDOCS) score ranges. The AOD ranged from 0 min to 157 min with a median of 11 min. When data were grouped by NEDOCS score, there was a statistically significant difference in median AOD between the groups (p < 0.001), indicating the relationship between ED crowding and AOD. CONCLUSION: The median AOD was considered significant and raised concerns related to patient care and EMS system resource availability. The NEDOCS score had a positive correlation with AOD and should be further investigated as a potential marker for determining diversion status or for destination decision-making by EMS personnel.

Performance of emergency physicians utilizing a video-assisted semi-rigid fiberoptic stylet for intubation of a difficult airway in a high-fidelity simulated patient: a pilot study.

BACKGROUND: This study was designed to evaluate emergency physician success and satisfaction using a video-assisted semi-rigid fiberoptic stylet, the Clarus Video System (CVS), during a simulated difficult airway scenario. FINDINGS: Emergency physicians (EPs) of all levels were first shown a brief slide show and three example videos, and then given 20 min to practice intubating a mannequin using both the CVS and standard direct laryngoscopy (DL). The mannequin was then placed in a c-collar and set to simulate an apneic patient with an edematous tongue and trismus. Each EP was given up to three timed attempts with each technique. They rated their satisfaction with the CVS, usefulness for their practice, and the effectiveness of the tutorial. Direct laryngoscopy had a 65% success rate on the first attempt, 20% on the second, and 15% required three or more. The CVS had a 100% success rate with a single attempt. Average time for independent DL attempts was 43.41 s (SD = ±26.82) and 38.71 s (SD = ±34.14) with CVS. Cumulative attempt times were analyzed and compared (DL = 74.55 ± 68.40 s and CVS = 38.71 ± 34.14 s; p = 0.028). EPs rated their satisfaction with, and usefulness of, the CVS as ≥6 out of 10. CONCLUSION: Emergency physicians were able to successfully intubate a simulated difficult airway model on the first attempt 100% of the time. Emergency physicians were satisfied with the CVS and felt that it would be useful in their practice.

Case report: Delayed subclavian vein injury secondary to clavicular malunion.

BACKGROUND: Fractures of the clavicle are extremely common, representing 2.6-12% of all fractures and 35-44% of all shoulder girdle injuries; 69-82% of these fractures occur in the middle third of the clavicle. Vascular injuries relating to clavicle fracture are usually due to extreme force applied to the clavicle in an acute setting. No other reports of delayed subclavian vein laceration were found on literature search. OBJECTIVES: We present this case to increase awareness among emergency physicians of the potential delayed presentation of this rare condition. CASE REPORT: A 21-year-old man presented to the Emergency Department with acute swelling of the base of the neck after carrying a heavy load on his left shoulder the night before. He had been recovering from a clavicle fracture for 2 months. Malunion of his left midshaft clavicle fracture led to subclavian vein injury and formation of a large hematoma secondary to reinjury that occurred at work the night before presentation. Computed tomography revealed a 9-cm hematoma at the fracture site. The patient was found to have a subclavian vein injury without evidence of arterial injury or nervous system involvement. The patient was admitted for observation and subsequently discharged without need for surgical intervention. CONCLUSION: Subclavian vein laceration is a rare complication of clavicle fracture. Patient education at discharge after conservative management is important due to the risk of vascular complications from malunion and reinjury.

Ambulance diversion and emergency department offload delay: resource document for the National Association of EMS Physicians position statement.

The emergency medical services (EMS) system is a component of a larger health care safety net and a key component of an integrated emergency health care system. EMS systems, and their patients, are significantly impacted by emergency department (ED) crowding. While protocols designed to limit ambulance diversion may be effective at limiting time on divert status, without correcting overall hospital throughput these protocols may have a negative effect on ED crowding and the EMS system. Ambulance offload delay, the time it takes to transfer a patient to an ED stretcher and for the ED staff to assume the responsibility of the care of the patient, may have more impact on ambulance turnaround time than ambulance diversion. EMS administrators and medical directors should work with hospital administrators, ED staff, and ED administrators to improve the overall efficiency of the system, focusing on the time it takes to get ambulances back into service, and therefore must monitor and address both ambulance diversions and ambulance offload delay. This paper is the resource document for the National Association of EMS Physicians position statement on ambulance diversion and ED offload time. Key words: ambulance; EMS; diversion; bypass; offload; delay.

Meningeal carcinomatosis diagnosed during stroke evaluation in the emergency department.

A 70-year-old female presented to the emergency department with a 3-day history of intermittent dysphasia and right facial droop. Computed tomography (CT) and magnetic resonance imaging (MRI) were obtained, and the patient was found to have meningeal carcinomatosis, also known as leptomeningeal metastases. Meningeal carcinomatosis is a rare metastatic complication of some solid tumors and hematopoietic neoplasms, and has a median survival rate of 2.4 months. The role of the emergency physician is to appropriately diagnose this condition, treat emergent side effects, provide symptomatic relief, and ensure multi-disciplinary management.
