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.

Improving prehospital stroke diagnosis using natural language processing of paramedic reports.
Accurate prehospital diagnosis of stroke by emergency medical services (EMS) can increase treatments rates, mitigate disability, and reduce stroke deaths. IN this study, the investigators aimed to develop a model that utilized natural language processing of EMS reports and machine learning to improve prehospital stroke identification. The investigators conducted a retrospective study of patients transported by the Chicago EMS to 17 regional primary and comprehensive stroke centers.

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.

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.
