About this study
Official title: Evaluation of an Enhanced Community First Responder Support System to Improve Bystander Cardiopulmonary Resuscitation Quality for Patients Experiencing Out-of-hospital Cardiac Arrest
The rise in out-of-hospital cardiac arrest (OHCA) cases in Singapore highlights the need for effective bystander cardiopulmonary resuscitation (BCPR). Despite many lay responders performing CPR, survival rates with good neurological outcomes have not significantly improved, prompting research into the quality of CPR as a critical factor. The study by Gallagher EJ et al. showed a significant survival improvement with high-quality CPR.
To address this, the Unit of Pre-hospital and Emergency Research (UPEC) trained thousands of community first responders (CFRs) in simplified CPR techniques using hands-only and DA-CPR methods. A significant innovation is the CPRcard®, developed by Laerdal in Norway, which offers real-time feedback on the quality of chest compressions. However, only 36% of CFRs using the CPRcard® achieved the desired compression standards, indicating room for improvement.

The study proposes enhancing CFR support with information communication technology (ICT), enabling two-way audio and one-way video communication between CFRs and dispatchers. This aims to reduce stress among responders, increase their willingness to engage with OHCA alerts, and improve CPR quality.
The clinical trial in Singapore will compare the current system against the enhanced CFR support system (eCSS), focusing on the real-time relay of CPR performance data, communication ease, and implementation factors. The high-quality CFR and OHCA registries in Singapore provide a robust setting for this research, aiming to enhance CPR delivery and improve OHCA outcomes through technology and real-time support.

Questions about this trial
What is this clinical trial studying?
A study testing CPRCard + TCPR Link App and Web and CPRCard Only in people with Out-Of-Hospital Cardiac Arrest, run by Singapore General Hospital at 1 site in Singapore.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 13 Apr 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 Singapore. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Fahad J Siddiqui, MSc (+6566017951, fahad.siddiqui@duke-nus.edu.sg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Good Chest Compression Depth (4-6cm) (time frame: Throughout chest compression before handing over to EMS (up to 24 hours)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06530433, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Apr 2026.
