Outcomes of in-hospital cardiac arrest among hospitals with and without telemedicine critical care.
This study compared survival rates for inpatients who suffered in-hospital cardiac arrest (IHCA) who had access to Telemedicine Critical Care (TCC) during nights and weekends (off-hours) compared to those who did not. The authors identified 44,585 adults at 280 U.S. hospitals in the Get With The Guidelines® - Resuscitation registry who suffered IHCA in an Intensive Care Unit (ICU) or hospital ward between July 2017 and December 2019. The majority (60.6%) of IHCAs occurred in an ICU, and 32.2% participants suffered IHCA at hospitals with TCC. No difference was found in acute resuscitation survival rates or survival to discharge rates for either IHCA between TCC and non-TCC hospitals. Timing of cardiac arrest did not modify the association between TCC availability and acute resuscitation survival or survival to discharge.

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.

Estimated population access to acute stroke and telestroke centers in the US, 2019.
In order to provide an update on population-level access to stroke care, the investigators estimated the proportion of the US population with access to an ED with acute stroke capabilities and assessed the specific contribution of telestroke services to US population access. They observed a substantial increase in population access to acute stroke care in this cross-sectional study relative to previous reports using alternative methods, likely due to the extensive and ongoing work to improve stroke systems of care, including greater stroke center accreditation and expansion of telestroke capacity.

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.

Lack of racial and ethnic-based differences in acute care delivery in intracerebral hemorrhage.
Int J Emerg Med 2021 Jan 19;14(1):6. doi: 10.1186/s12245-021-00329-w.
Early diagnosis and treatment of intracerebral hemorrhage (ICH) is thought to be critical for improving outcomes. In this study the investigators examined whether racial or ethnic disparities existed in acute care processes in the first hours after ICH. The investigators found no evidence of racial/ethnic disparities in acute care processes or outcomes in ICH. English as first language, however, was associated with slower care processes.

Comparing two proximal measures of unrecognized clinical deterioration in children.
Critical deterioration events (CDEs) and emergency transfers (ETs) are two proximal measures to cardiopulmonary arrest, and both aim to evaluate how systems recognize and respond to clinical deterioration in children. This retrospective observational study sought to (1) characterize CDEs and ETs by timing, overlap, and intervention category, and (2) evaluate the performance of the watcher identification system and the pediatric early warning score (PEWS) to identify patients who experience these events.

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.

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%.

System-based interprofessional simulation-based training program increases awareness and use of rapid response teams.
The objective of this study was to develop and implement an interprofessional simulation-based training program for rapid response and cardiac arrest emergencies with emphasis on early recognition and effective communication. The researchers concluded that their study demonstrated that rapid response team underuse due to system barriers may be overcome by this type of program targeting specific needs of the institution.
