Comparing sources of disruptions to telemedicine-enabled stroke care in an ambulance.
This study investigated the nature and source of disruptions in an ambulance during the telemedicine-based caregiving process for stroke patients to enhance the ambulance design for supporting telemedicine-based care. Thirteen simulated telemedicine-based stroke consults were video recorded and then coded and analyzed using an existing systems-based flow disruption (FD) taxonomy. Factors that impacted disruptions included seat size, arrangement of assessment equipment, location of telemedicine equipment, and design of the telemedicine camera. The left ambulance seat zone and head of the patient bed had more environmental hazard-related disruptions, while the right zone was more prone to interruptions and communication-related disruptions.

A novel emergency medical services protocol to improve treatment time for large vessel occlusion strokes.
This paper describes the outcomes of a pilot study that used novel emergency medical services (EMS) protocol to expedite transfer of patients with large vessel occlusions (LVOs) to a comprehensive stroke center (CSC). The pilot study took place from Oct. 1, 2020 to Feb. 22, 2021 with Indianapolis EMS providers. In patients with possible LVO, the providers remained at the bedside until the clinical assessment and CT angiography were complete. This 5-month mixed methods study measured case-control assessment of the protocol, number of transfers, safety during transport, and time saved in transfer compared to emergency transfers via conventional interfacility transfer agencies. The protocol was used 42 times during the study period, with four patients found to have LVOs and transferred to a CSC. Median time from decision-to-transfer to arrival at the CSC was 27.5 minutes compared to 314.5 minutes for acute non-stroke transfers during the same period.

An exploratory study investigating the barriers, facilitators, and demands affecting caregivers in a telemedicine integrated ambulance-based setting for stroke care.
This study investigates the impact of telemedicine on workload, teamwork, workflow, and communication of geographically distributed caregivers delivering stroke care in ambulance-based telemedicine. Simulated stroke sessions were conducted with selected caregivers, then followed with a survey and interviews. Findings showed that barriers included frustration with equipment, the loss of personal connection of the neurologists with the patients, and physical constraints in the ambulance. Facilitators included live visual communication increasing teamwork and efficiency, the ease of access to neurologist, increased flexibility, and high overall satisfaction and usability.

Prehospital comprehensive stroke center vs primary stroke center triage in patients with suspected large vessel occlusion stroke.
This study’s objective was to evaluate the association of a regional prehospital transport policy that directly triages patients with suspected large vascular occlusion (LVO) stroke to the nearest comprehensive stroke center with rates of endovascular therapy (EVT). This retrospective, multicenter preimplementation-postimplementation study used an interrupted time series analysis to compare treatment rates before and after implementation in patients with acute ischemic stroke (AIS) arriving at 15 primary stroke centers and 8 comprehensive stroke centers in Chicago, Illinois, via emergency medical services (EMS) transport from December 1, 2017, to May 31, 2019. Among 7709 individuals with stroke, 663 with AIS arrived within 6 hours of stroke onset by EMS transport. The EVT rate increased overall among patients with AIS postimplementation and among EMS-transported patients with AIS within 6 hours of onset. There were no differences in EVT rates in patients not arriving by EMS within the 6- to 24-hour window or by interhospital transfer or walk-in.

The cost of a fall among older adults requiring emergency services.
Researchers evaluated medical expenditures to 1 year among community-dwelling older adults who fell and required ambulance transport, including acute versus post-acute periods, the primary drivers of cost, and comparison to baseline expenditures. They found that older adults who fall and require emergency services have increased healthcare expenditures compared with baseline, particularly during the post-acute period. Comorbidities, noninjury medical conditions, fracture type, and surgical interventions were independently associated with increased costs.

Effect of acute stroke care regionalization on intravenous alteplase use in two urban counties.
Investigators sought to determine whether increasing access to primary stroke centers (regionalization) led to an increase in intravenous alteplase use in acute ischemic stroke patients. Studying two urban counties in the western region of US that regionalized acute stroke care, they found that in Santa Clara County, intravenous alteplase was administered to 1.7% of patients in the pre-regionalization period and 2.1% in the post-regionalization period, while in San Mateo County, the numbers were 1.3% and 3.2%, respectively. In the post-regionalization phase, San Mateo County had greater change in paramedic stroke detection, higher number of transports to primary stroke centers, and more frequent use of intravenous alteplase at stroke centers. They concluded that greater post-regionalization improvements in San Mateo County contributed to significantly improved county-level thrombolysis use than Santa Clara County.

Assessment of paramedic performance on difficult airway simulation.
The purpose of this study was to assess paramedic comprehensive airway management practices during a difficult airway simulation through which paramedics were obligated to consider alternatives to endotracheal intubation (ETI). The investigators concluded that in a difficult airway management scenario designed for low ETI success rates, even experienced paramedics were challenged with comprehensive airway management. This was exemplified by difficulties with the use of backup airway devices.

Delays in recognition of the need for telephone-assisted CPR due to caller descriptions of chief complaint.
The objective of this study was to test if caller descriptions of chief complaint delays emergency medical dispatchers' (EMDs) recognition of the need for telephone-assisted CPR (T-CPR). The investigators conducted an analysis of N = 433 cardiac arrest calls from six large call centers in the United States. They concluded that caller chief complaint description affected the time to recognition of the need for T-CPR.

Comparative effectiveness of analgesics to reduce acute pain in the prehospital setting.
The objectives of this study were to assess comparative effectiveness and harms of opioid and nonopioid analgesics for the treatment of moderate to severe acute pain in the prehospital setting. Among the investigators’ conclusions were that as initial analgesia, opioids were no different than ketamine, APAP, and NSAIDs in reducing acute pain in the prehospital setting. Opioids may cause fewer total side effects than ketamine, but more than APAP or NSAIDs.

Injured older adults transported by emergency medical services: one year outcomes by POLST status.
Advance care planning documents, including Physician Orders for Life-Sustaining Treatment (POLST), are intended to guide care near end of life, particularly in emergency situations. Yet, research on POLST during emergency care is sparse. This study examined one year outcomes, by Physician Orders for Life-Sustaining Treatment status, of injured adults transported by EMS. The investigators concluded that among injured older adults transported by ambulance in Oregon, one in 5 had an active POLST form at the time of 9-1-1 contact, the prevalence of which increased over the following year.

Evaluating pediatric advanced life support in emergency medical services with a performance and safety scoring tool.
This study used simulation to evaluate Pediatric Advanced Life Support (PALS) guideline performance in pediatric emergency medical service (EMS) care and to introduce this easy-to-use tool to score guideline compliance and patient safety. Standard pediatric resuscitation simulations with a child manikin were created. The manikin was presented as a choking 6-year-old with a complex medical history who is unconscious and apneic, with bradycardic pulse. Teams were expected to monitor vitals, initiate airway management and CPR, and establish vascular access and administer epinephrine based on PALS guidelines. The authors observed 34 EMS teams providing care in P-OHCA simulations. Teams were found to be proficient in assessing vitals, using correct-sized equipment, intubation, and confirmation of tube placement. The teams were delayed in initiating positive pressure ventilation (PPV) and chest compressions, with many teams (53%) deviating from guidelines in chest compression. Half the teams performed continuous compressions before establishing an advanced airway and one team did not perform compressions. Twenty teams also deviated from medication guidelines with 12 teams failing to administer epinephrine, six teams underdosing, and two teams overdosing by more than 20%.

Association of race/ethnicity with emergency department destination of emergency medical services transport.
The authors examined the patterns of emergency department (ED) destination of emergency medical services (EMS) transport according to patient race/ethnicity and compared the patterns between those transported by EMS and those who did not draw on EMS. Using Medicare claims data, they found race/ethnicity variation in ED destination for patients using EMS transport, with black and Hispanic patients more likely to be transported to a safety-net hospital ED compared with white patients living in the same zip code.

Ambulance diversions following public hospital emergency department closures.
The purpose of this study was to examine whether hospitals are more likely to temporarily close their emergency departments to ambulances, through ambulance diversions, if neighboring diverting hospitals are public vs private. Results showed that sample hospitals respond differently to diversions by neighboring public (vs private) hospitals. The authors conclude that these findings suggest that these hospitals might be strategically declaring ambulance diversions to avoid treating low-paying patients served by public hospitals.

Long-term outcomes among injured older adults transported by emergency medical services.
This study examined the outcomes of injured older adults who were transported by emergency medical services (EMS) to the hospital. Older adults 65 years and older who were transported by 44 EMS agencies to 51 hospitals in 2011 were included and then had a 12-month follow-up through December 31, 2012. The majority of older adults were transported after a fall (84.5%). Serious injuries occurred in 3.5% with a serious extremity injury being the most common (17.8%). Mortality rates for older adults with severe injuries ranged from 1.6% in the hospital to 20.3% at 1 year. The most common causes of death was cardiovascular diseases and dementia.

Correlation between paramedic disaster triage accuracy in screen-based simulations and immersive simulations.
This study examined the effectiveness of adding a screen-based simulation (SBS) to immersive simulation of a disaster for triage education of paramedics and emergency medical technicians (EMTs). A randomized controlled trial (RCT) was conducted with emergency medical personnel who had completed an immersive simulation of a school shooting, interacted with an SBS for 13 weeks, and completed the immersive simulation again. The participants were divided into groups: one who had gone through the Seconds to Survival (60S) disaster triage SBS and the other who had not. There was a significant increase in triage accuracy with immersive simulation, but SBS did not correlate with performance in the immersive simlation.

Optimization of prehospital triage of patients with suspected ischemic stroke.
Prehospital routing algorithms for patients with suspected stroke because of large vessel occlusions should account for likelihood of benefit from endovascular therapy (EVT), risk of alteplase delays, and transport times. In this study, the investigators present a mathematical decision model that determines ideal prehospital routing recommendations for patients with suspected stroke because of large vessel occlusions, with consideration of patient characteristics and location at onset.

Qualitative study to understand ordering of CT angiography to diagnose pulmonary embolism in the emergency room setting.
The purpose of the study was to better understand, using semi-structured interviews, the decision making behind the ordering of CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism (PE) in the emergency department. The authors found that EM providers were the main drivers of CTPA ordering, and there was a marginalized role for the radiologist. Experience- and gestalt-based heuristics were the main influencers of CTPA ordering.

A randomized comparison of in-hospital rescuer positions for endotracheal intubation in a difficult airway.
The objective of the study was to compare in-hospital emergency medicine (EM) trainees' performance on endotracheal intubation (ETI) delivered from both the seated and standing positions. The study concluded that the position of the in-hospital provider, whether seated or standing, had no effect on the provider's ETI performance. Since environmental circumstances sometimes necessitate alternative positioning for effective ETI administration, the findings suggest that there may be value in training residents to perform ETI from both positions.

Accuracy and reliability of emergency department triage using the emergency severity index: an international multicenter assessment.
This study assessed the accuracy and variability of triage score assignment by emergency department (ED) nurses using the Emergency Severity Index (ESI) in 3 countries. It found that the concordance of nurse-assigned ESI score with reference standard was universally poor and variability was high. Although the ESI is the most popular ED triage tool in the United States and is increasingly used worldwide, its findings point to a need for more reliable ED triage tools.

Cincinnati prehospital stroke scale can identify large vessel occlusion stroke.
This study explores the hypothesize that a cut-off score of the Cincinnati Prehospital Stroke Scale (CPSS), an assessment tool currently used by emergency medical services (EMS) providers, can be used to identify large vessel occlusion (LVO). Patients with acute ischemic stroke arriving via EMS at a high-volume stroke center in a large city were identified in a prospective, single-center registry. LVO was confirmed via head and neck vessel imaging and CPSS scores were abstracted from pre-hospital EMS records. The researchers conclude that a CPSS score of 3 identifies LVO in AIS patients reliably, and that EMS providers may be able to use the CPSS with a cut-off score to screen for patients with suspected LVO.
