Barriers and facilitators to CPR training and performing CPR in an older population most likely to witness cardiac arrest: A national survey

BackgroundBystander CPR rates are lowest at home, where 85% of out-of-hospital cardiac arrests occur. We sought to identify barriers and facilitators to CPR training and performing CPR among older individuals most likely to witness cardiac arrest.MethodsWe selected independent-living Canadians aged ≥55 using random-digit-dial telephone calls. Respondents were randomly assigned to answer 1 of 2 surveys eliciting barriers and facilitators potentially influencing either CPR training or performance. We developed survey instruments using the Theory of Planned Behavior, measuring salient attitudes, social influences, and control beliefs.ResultsDemographics for the 412 respondents (76.4% national response rate): Mean age 66, 58.7% female, 54.9% married, 58.0% CPR trained (half >10 years ago). Mean intentions to take CPR training in the next 6 months or to perform CPR on a victim were relatively high (3.6 and 4.1 out of 5). Attitudinal beliefs were most predictive of respondents’ intentions to receive training or perform CPR (Adjusted OR; 95%CI were 1.81; 1.41–2.32 and 1.63; 1.26–2.04 respectively). Respondents who believed CPR could save a life, were employed, and had seen CPR advertised had the highest intention to receive CPR training. Those who believed CPR should be initiated before EMS arrival, were proactive in a group, and felt confident in their CPR skills had the highest intention to perform CPR.InterpretationAttitudinal beliefs were most predictive of respondents’ intention to complete CPR training or perform CPR on a real victim. Behavioral change techniques targeting these specific beliefs are most likely to make an impact.
