Summary
A new guided Advanced Cardiovascular Life Support (ACLS) mobile app improved cardiac arrest outcomes and leader confidence compared to traditional pocket cards. This tool shows potential for standardizing in-hospital cardiac arrest management.
Area of Science:
- Medical Education
- Emergency Medicine
- Cardiology
Background:
- In-hospital cardiac arrest management variability impacts patient outcomes.
- Current clinical decision aids like American Heart Association (AHA) Advanced Cardiovascular Life Support (ACLS) pocket cards and mobile apps may lack comprehensive guidance.
- Standardization of ACLS protocols is crucial for improving resuscitation success rates.
Purpose of the Study:
- To develop and evaluate a novel, guided ACLS mobile application for managing in-hospital cardiac arrest.
- To compare the performance of resident physicians using the guided ACLS app versus traditional AHA ACLS pocket cards in simulated cardiac arrest scenarios.
- To assess the impact of the guided ACLS app on return of spontaneous circulation (ROSC), code leader stress and confidence, guideline adherence, and error rates.
Main Methods:
- A randomized controlled trial involving 46 resident physicians leading simulated cardiac arrest teams.
- Participants were randomized to use either AHA pocket cards (N=22) or the guided ACLS app (N=24).
- Primary outcome was successful ROSC; secondary outcomes included code leader stress, confidence, guideline adherence, and errors. A focus group provided qualitative feedback.
Main Results:
- App users achieved a significantly higher ROSC rate (50% vs. 18%, p=0.024).
- Significant improvements were observed in correct thrombolytic administration (54% vs. 23%, p=0.029), backboard use (96% vs. 27%, p<0.001), and end-tidal CO2 monitoring (58% vs. 27%, p=0.033) among app users.
- App users reported significantly higher confidence (p=0.005), and 82% preferred the app over pocket cards.
Conclusions:
- The guided ACLS mobile app demonstrates potential for enhancing user confidence and adherence to AHA ACLS guidelines.
- The app may serve as a valuable tool for standardizing in-hospital cardiac arrest management.
- Further validation studies are recommended to confirm the app's efficacy in real-world clinical settings.

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

2
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...
