Filter by:Background Since 2001 when the Danish Cardiac Arrest Registry was first established several large-scale interventions aimed at the entire Danish population from all ages have been initiated. BLS courses have been made mandatory in all primary schools since January 2005, and when taking driver's license since October 2006. This has resulted in a steep increase in the number of Danish citizens attending a BLS course to approximately 3-4.5% of the entire population annually. Aim The aim of this study is to investigate the effect of the numerous population-based interventions to increase bystander basic life support (BLS) prior to arrival of Emergency Medical Services (EMS) to persons suffering from out-of-hospital cardiac arrest (OHCA). Further this study aim at identifying geographical areas with low frequency of Basic Life Support (BLS) education and low level of bystander initiated BLS to enable direction of further educational efforts in the future to increase survival. Methods By coupling the geographical coordinates of the BLS course certificates with the GPS coordinates of cardiac arrests, the effects of BLS courses on bystander CPR rates and survival can be investigated. In collaboration with researchers from Aalborg University Hospital, the entire Danish geography have been divided into digital squares of 100x100m and combined with sociodemographic data. This data will be coupled with national administrative parish of Denmark comprising some 2201 geographical units of approximately equal size. This geographic model has been combined with data from the Danish Cardiac Arrest Registry, the National Danish Patient registry and the Central Person Registry. The current study has access to the geodata of the GPS coordinates of Danish citizens who have attained a BLS course certificate between 2016 and 2019. By combining the two datasets in national administrative parish's of Denmark, the investigators are able to calculate the correlation between BLS course certificates, the rate of bystander CPR and survival of OHCA. Further, the investigators are able to pinpoint geographic areas where improvements of the BLS education level and bystander initiated BLS rates can be made. To involve laypersons in the current study, focus group interviews consisting of BLS course participants will be performed to explore the views of the attending laypersons on the project and revise accordingly. Expected outcome To identify geographical association between bystander CPR prior to EMS arrival and BLS training. A verified account of number of BLS certificates issued annually and geographical visual map of first aid certificates. Finally, it is a goal to be able to identify areas with which to start with better education. That is, areas where there is low frequency of courses and low frequency of bystanders initiated BLS.
Aim The aim of the study is to characterize the typical basic life support (BLS) course participant. The characterization include age, sex, education, ethnicity, income, health care data and cohabitation. All data will be compared with that of the general population. Hereby the study wish identify potential focus areas for recruitment of willing and able bystanders to increase survival. Furthermore, this study will provide a foundation for evaluation of current initiatives. Significance In Denmark, several population-based campaigns have been initiated to increase the amount of able and willing laypersons to assist at out-of-hospital cardiac arrest (OHCA). The main focus has been on increasing the quantity of laypersons attending BLS courses. Even measures of changing legislation mandating course participation have been passed and implemented. Estimates state that approximately 3-4.5% of the entire Danish population participates in BLS courses annually. Consequently, a substantial amount of resources has been spent on educating and certifying laypersons in BLS on a population level. In this study, the characteristics of these BLS course participants will be described. This will provide the basis for evaluation of already implemented interventions. Additionally, this study will be able to support course distributors, foundations and national councils in making strategies for further recruitment based on evidence. The present study will assist in pinpointing society groups with a theoretical bystander potential, but low level of BLS education. This can guide future efforts in trying to improve bystander initiated cardiopulmonary resuscitation (CPR) and survival from OHCA. Methods The study population includes all Danish citizens who attended a BLS training course certificate from 2016-2018 above the age of 15. This cut off is based on the earliest mandatory BLS training in primary school. Using Personal Identifications Numbers (PIN) of BLS course participant from January 1st, 2016 to December 31st, 2018, data will be extracted and delivered anonymously, including information on age, sex, income, education, ethnicity and cohabitation, from the Statistics Denmark. The relative risk of BLS course attendance stratified by education and income level, cohabitation status, age of youngest child, urbanization level, sex and ethnicity of the Danish BLS course participants compared to the general population will be presented. Prevalence of BLS courses participants by age and sex will be analyzed and graphically display and prevalence of BLS course participants by income and age will be calculated by regression models. A layperson focus group interview consisting of BLS course participants will be conducted to explore the attending courses participants views of the project and to revise accordingly. Anonymity is secured through a data processing agreement between the Danish First Aid Council and Statistics Denmark, facilitated by the Copenhagen Emergency Medical Services. An application will be formulated to the Danish Data protection agency regarding storage of data. Expected outcome A characterization of the typical BLS course participants in Denmark with median age, sex, cohabitation, income and education. The association between sociodemographic characteristics of BLS course participants and relevant prevalence's by the entire population will be presented.
