Factors impeding dispatcher-assisted telephone cardiopulmonary resuscitation

Ann Emerg Med. 2003 Dec;42(6):731-7. doi: 10.1016/s0196-0644(03)00423-2.


Study objective: Dispatcher-assisted telephone cardiopulmonary resuscitation (CPR) instruction can increase the proportion of sudden cardiac arrest victims who receive bystander CPR and has been associated with improved survival. Most sudden cardiac arrest victims, however, do not receive bystander CPR. The study objective was to examine factors that may impede implementation of telephone CPR.

Methods: We reviewed dispatcher audio recordings and emergency medical services reports for 404 cases of sudden cardiac arrest that occurred from July 1, 2000, to June 30, 2002, in the study county to assess the phase (1, instructions not offered; 2, instructions offered but declined; or 3, instructions offered and accepted but CPR not implemented) and specific factors within each phase that potentially impede telephone CPR.

Results: Twenty-five percent (99/404) of victims received bystander CPR without dispatch assistance, 34% (139/404) received telephone CPR, and 41% (166/404) did not receive bystander CPR. Each phase of telephone CPR process impeded the implementation of CPR: (1) instructions not offered in 48% (80/166); (2) instructions offered but declined in 31% (52/166); and (3) instructions offered and accepted but CPR not implemented in 21% (34/166). During the first phase, telephone CPR was potentially impeded most frequently because the victim was reported to have signs of life (51/80, 64%); during the second and third phases, telephone CPR was most often impeded because of bystander physical limitation (32/86, 37%). Emotional distress, disease transmission, disagreeable victim characteristics, or medicolegal concerns uncommonly impeded telephone CPR (10/86, 12%).

Conclusion: Factors potentially impeding telephone CPR can be identified. Although many are logistically challenging, some may be addressable and hence provide opportunities to strengthen the chain of survival.
