Video dispatcher CPR no better than phone

Telemedicine-assisted vs conventional telephone instruction in cardiopulmonary resuscitation: the TACTIC cluster randomized trial
Resuscitation · Added 29 July 2026

Cluster-randomized trial of 108 OHCA patients compared video-assisted dispatcher CPR instruction with conventional telephone instruction, finding no difference in bystander CPR rates (87.3% vs 92.5%, p=0.53) or ongoing CPR at EMS arrival, but significantly lower protocol compliance in the telemedicine group.

Study type

RCT

Design

Pragmatic pilot cluster-randomised controlled trial

Participants

108 adults with non-traumatic OHCA (55 TA-CPR, 53 DA-CPR)

Main finding

Bystander CPR rate 87.3% (TA-CPR) vs 92.5% (DA-CPR), p=0.53; ongoing CPR at EMS arrival 76.4% vs 84.9%, p=0.33. Protocol compliance significantly lower in TA-CPR (69.1% vs 92.5%).

Caveat

Small pilot with imbalanced baseline characteristics (younger patients, more shockable rhythms in TA-CPR) and limited power.

Bottom line

Hypothesis-generating

Learning goal

Weigh the value of video-assisted dispatcher CPR against conventional telephone instruction when supporting bystanders during cardiac arrest.
