Acute cardiac care & resuscitationCohort study
Video-vs audio-instructed dispatcher-assisted cardiopulmonary resuscitation (CPR) and outcomes after out-of-hospital cardiac arrest: a nationwide registry-based cohort study
- retrospective, nationwide cohort study
- registry-based
- multivariate logistic regression
- propensity score-matching (PSM) analyses
Authors' conclusion
DA-CPR in the VG was associated with associated with higher odd of favorable neurological outcomes and survival in patients with OHCA, while instruction and CPR initiation times were modestly longer. Optimizing protocols to reduce video transition workflows and incorporating dispatch-center and technical variables should be priorities for future prospective studies.
