Dispatch Categories as Indicators of Out-of-Hospital Time Critical Interventions and Associated Emergency Department Outcomes.

Objectives: Emergency medical services (EMS) systems increasingly grapple with rising call volumes and workforce shortages, forcing systems to decide which responses may be delayed. Limited research has linked dispatch codes, on-scene findings, and emergency department (ED) outcomes. This study evaluated the association between dispatch categorizations and time-critical EMS responses defined by prehospital interventions and ED outcomes.

Implementation of a prehospital whole blood program: Lessons learned.

Early blood administration by Emergency Medical Services (EMS) to patients suffering from hemorrhagic shock improves outcomes. Prehospital blood programs represent an invaluable resuscitation capability that directly addresses hemorrhagic shock and mitigates subsequent multiple organ dysfunction syndrome. Prehospital blood programs must be thoughtfully planned, have multiple safeguards, ensure adequate training and credentialing processes, and be responsible stewards of blood resources.

Efficacy and Safety of Prehospital Diltiazem.

Objective: This study assesses the likelihood of clinical improvement and adverse events from EMS-administered diltiazem. Current prehospital protocols direct paramedics to administer diltiazem, a calcium channel blocker, to decrease the heart rate (HR) of symptomatic, hemodynamically stable patients with rapid atrial fibrillation. However, diltiazem can also cause systemic hypotension and bradycardia, which can precipitate end-organ injury.

Do prehospital sepsis alerts decrease time to complete CMS sepsis measures?

Introduction: In an effort to improve sepsis outcomes the Centers for Medicare and Medicaid Services (CMS) established a time sensitive sepsis management bundle as a core quality measure that includes blood culture collection, serum lactate collection, initiation of intravenous fluid administration, and initiation of broad-spectrum antibiotics. Few studies examine the effects of a prehospital sepsis alert protocol on decreasing time to complete CMS sepsis core measures.

Methods: This study was a retrospective cohort study of patients transported via EMS from December 1, 2018 to December 1, 2019 who met the criteria of the Maryland Statewide EMS sepsis protocol and compared outcomes between patients who activated a prehospital sepsis alert and patients who did not activate a prehospital sepsis alert.

Safety of Nurse-Managed Inhaled Nitric Oxide During Critical Care Interfacility Transport.

Inhaled nitric oxide (iNO) is an advanced therapy typically managed by physicians and respiratory therapists in order to increase arterial oxygenation and decrease pulmonary arterial pressure. The Johns Hopkins Lifeline Critical Care Transportation Program (Lifeline) initiated a novel nurse-managed iNO protocol in order to optimize the oxygenation of critically ill patients during interfacility transport. This study was a retrospective chart review of adverse events associated with iNO initiation or continuation by Lifeline on patients transported from March 1, 2020, to August 1, 2022.

Establishing consensus-based high-acuity low-occurrence skills for EMS physicians: A pilot survey of EMS fellowship faculty.

Background: The specialty of emergency medical services (EMS) medicine focuses on providing out-of-hospital patient care, including initial stabilization, treatment, and transport in specially equipped vehicles including ambulances and airframe platforms to hospitals and better-resourced destinations. The Core Content of EMS Medicine outlines the knowledge, procedures, and psychomotor skills relevant to prehospital patient care. However, this document does not specify the high-consequence skills that are infrequently performed and that carry high levels of complexity as well as potential morbidity.

Temporal Changes in Epinephrine Dosing in Out-of-Hospital Cardiac Arrest: A Review of EMS Protocols across the United States.

Background: Administration of epinephrine has been associated with worse neurological outcomes for survivors of out-of-hospital cardiac arrest. The publication of the 2018 PARAMEDIC-2 trial, a randomized and double-blind study of epinephrine in out-of-hospital cardiac arrest, provides the strongest evidence to date that epinephrine increases return of spontaneous circulation (ROSC) but not neurologically intact survival. This study aims to determine if Emergency Medical Services (EMS) cardiac arrest protocols have changed since the publication of PARAMEDIC-2.

Impacts of an EMS Hospital Liaison Program on Ambulance Offload Times: A Preliminary Analysis.

Introduction: Ambulance patients who are unable to be quickly transferred to an emergency department (ED) bed represent a key contributing factor to ambulance offload delay (AOD). Emergency department crowding and associated AOD are exacerbated by multiple factors, including infectious disease outbreaks such as the coronavirus disease 2019 (COVID-19) pandemic. Initiatives to address AOD present an opportunity to streamline ambulance offload procedures while improving patient outcomes.

A Statewide EMS Viral Syndrome Pandemic Triage Protocol: 24 Hour Outcomes.

Early during the COVID-19 pandemic, Emergency Medical Services (EMS) systems encountered many challenges that prompted crisis-level strategies. Maryland's statewide EMS system implemented the which contained a decision tool to help identify patients potentially safe for self-care at home. This study assessed the effects of the and the safety of referring patients for self-care at home.

Decision Making and Interventions During Interfacility Transport of High-Acuity Patients With Severe Acute Respiratory Syndrome Coronavirus 2 Infection.

Objective: There are limited data regarding the typical characteristics of coronavirus disease 2019 (COVID-19) patients requiring interfacility transport or the clinical capabilities of the out-of-hospital transport clinicians required to provide safe transport. The objective of this study is to provide epidemiologic data and highlight the clinical skill set and decision making needed to transport critically ill COVID-19 patients.

Methods: A retrospective chart review of persons under investigation for COVID-19 transported during the first 6 months of the pandemic by Johns Hopkins Lifeline was performed.

A Critical Care Transport Program's Innovative Approach to Safety During the Coronavirus Disease 2019 Pandemic.

Objective: The coronavirus disease 2019 (COVID-19) pandemic has resulted in the frequent transfer of critically ill patients, yet there is little information available to assist critical care transport programs in protecting their clinicians from disease exposure in this unique environment. The Lifeline Critical Care Transport Program has implemented several novel interventions to reduce the risk of staff exposure.

Methods: Several safety interventions were implemented at the beginning of the COVID-19 pandemic.

Implementing a Statewide Prehospital Sepsis Protocol: Perspectives of Emergency Medical Services Medical Directors.

Background Sepsis is a medical emergency that requires prompt recognition and treatment. Multiple Emergency Medical Services (EMS) agencies across the United States have implemented sepsis protocols. In 2016, Maryland instituted its own state-wide EMS sepsis protocol which includes fluid resuscitation, vasopressor administration, and requires alerting the hospital of an incoming sepsis patient.
