People overestimate success of CPR

(HealthDay)—Individuals overestimate the success rate of cardiopulmonary resuscitation (CPR), according to a study published online July 13 in the Emergency Medicine Journal.

Norkamari Shakira Bandolin, M.D., from University of California Davis in Sacramento, and colleagues surveyed 500 adult emergency department patients and their companions to assess their expectations about CPR.

The researchers found that 53 percent of respondents had performed or witnessed CPR. Nearly two-thirds (64 percent) had participated in a CPR course. For the vast majority of respondents (>95 percent), television was the main source of information about CPR. More than half of respondents estimated the success rate of CPR to be >75 percent in all situations. Age, sex, race, spiritual beliefs, and personal health care experience were unrelated to estimated CPR success rates. While >90 percent of respondents want to receive CPR, if needed, fewer than one-third had discussed CPR with a medical provider.
