About this study

Official title: Evaluation of CPR Training and Agonal Breathing Recognition Among New Taipei City Police Officers in Out-of-Hospital Cardiac Arrest Events

This study will evaluate an educational training program for police officers in New Taipei City, Taiwan. Police officers may arrive at out-of-hospital cardiac arrest events before emergency medical services and may be able to provide early cardiopulmonary resuscitation and automated external defibrillator support. However, abnormal gasping or agonal breathing can be mistaken for normal breathing and may delay recognition of cardiac arrest.

Participants will receive a single training session consisting of an adult CPR refresher course and agonal breathing recognition training. Anonymous online questionnaires will be completed before and immediately after the training. The study will compare pre-training and post-training questionnaire results to assess changes in agonal breathing recognition accuracy, CPR-related knowledge, and course satisfaction.

Read the detailed description

This is a single-arm, before-and-after educational intervention study conducted among active police officers in New Taipei City, Taiwan. The study is embedded in routine annual first aid training for police officers.

The intervention consists of a single training session. The first component is a 20-minute adult CPR refresher course covering the emergency response sequence, chest compression quality, compression depth and rate, and complications of chest compression. The second component is a 40-minute agonal breathing recognition session covering the pathophysiology and clinical presentation of agonal breathing, video-based recognition practice using real cases, and analysis of common recognition errors.

Before the training session, study information is provided and participants are invited to complete an anonymous online pre-training questionnaire using a QR code. Immediately after the training session, participants are invited to complete an anonymous online post-training questionnaire using a QR code. Questionnaire data will be used to evaluate changes in agonal breathing recognition accuracy, CPR-related knowledge, and overall learning outcomes. Course satisfaction will be assessed using the post-training questionnaire.

Participation is voluntary. The study collects anonymous questionnaire responses and does not involve patient-level clinical data or direct patient intervention. There is no long-term participant follow-up.

  • CPR Refresher and Agonal Breathing Recognition TrainingBehavioural

    A single-session educational training program consisting of a 20-minute adult CPR refresher course and a 40-minute agonal breathing recognition training session. The CPR refresher covers the emergency response sequence, chest compression quality, compression depth and rate, and complications of chest compression. The agonal breathing recognition session covers pathophysiology, clinical presentation, real-case video-based recognition practice, and analysis of common recognition errors.

Individual data sharing
No: Individual participant data will not be shared publicly because this study collects anonymous questionnaire responses in an occupational training setting, and public sharing of participant-level data was not included in the ethics-approved protocol. Study-related electronic data will be accessible only to the research team, stored securely, and deleted after the approved retention period. Aggregated results may be reported in conference presentations and journal publications.

The record says: finished, as of the sponsor's last update on 10 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Agonal Breathing Recognition Accuracy (time frame: Immediately before and immediately after the training session). It is what the study was designed to measure, not a finding.
