Abstract P75: Trends in Cardiopulmonary Resuscitation (CPR) 1985–1987 through 2000–2002: The Minnesota Heart Survey
Introduction: In cities where CPR training is widespread and CPR-trained bystanders respond, survival after cardiac arrest has been shown to be improved. The American Heart Association attributes the lack of reliable CPR statistics to the absence of a single agency to collect training information. We sought to describe trends in CPR training and use in the Minnesota Heart Survey (MHS).
Methods: MHS risk factor survey participants were randomly selected residents of the seven county Minneapolis-St. Paul metropolitan area (population of 2.8 million in 2002) ages 25–74, at five-year intervals from 1985– 87 to 2000 – 02. To determine patterns in CPR training and usage, several questions about CPR training and socio-demographic characteristics (age, race, education level, marital status) were asked during a home interview. Logistic regression was performed to examine trends in CPR training across survey years and within socio-demographic groups.
Results: In this serial cross-sectional study, with an average participation at the home interview of 82%, 10,198 men and 11,515 women were measured in five surveys. The proportion of adults trained in CPR increased significantly from 36% in 1985 to 65% in 2002. This increase was seen consistently across all age groups, with the youngest group age (25–34 years) showing an increase from 44% to 75%. There were no differences between males and females. Most trainees had been trained more than five years before interview. The self-reported use of CPR by these trained participants in an emergency situation was 13%, and did not increase significantly over the study period.
Conclusion: Almost all socio-demographic groups were characterized by a significant increase in prevalence of CPR training and in number of attempted resuscitations from 1985–1987 to 2000–2002. Our survey methodology could not determine quality of resuscitation attempt, which could vary with time since CPR training, nor ultimate outcome post-resuscitation attempt of the person receiving CPR.
