Simulation and educationCPR knowledge and attitude to performing bystander CPR among secondary school students in Norway☆
Introduction
Survival from out-of-hospital cardiac arrest (OHCA) depends on all the individual parts of the chain of survival,1, 2, 3 and immediate bystander cardiopulmonary resuscitation (CPR) is a major contributor to survival from OHCA,4, 5, 6, 7, 8 probably increasing survival fourfold.9 However, bystander CPR rates vary between 15 and 50% in OHCA.9, 10, 11, 12, 13 Layperson training and attitude to actually performing CPR in a given cardiac arrest situation, are both important factors in order to increase bystander contribution to OHCA survival.11, 14
According to the literature, both basic life support (BLS) training,10, 15, 16 and attitude to performing CPR,17, 18, 19 varies between countries. Both factors also differ between different age groups. In recent studies, the willingness to perform CPR varies considerably among high school students in e.g. Japan20 and New Zealand.21
To investigate knowledge of CPR and attitude to performing bystander CPR among young Norwegians, we questioned secondary school students about CPR training, self-reported experience with cardiac arrest situations, and how they think they would react in given cardiac arrest situations.

Materials and methods
800 questionnaires were distributed to second year students from the Specialization in General Studies Programme of nine secondary schools in the counties of Nordland and Troms (Norway). Approval was given by the Chief County Education Officers and the headmasters of the selected schools. Participation was voluntary and the form teachers were kindly asked to motivate the students to respond to the questionnaire. One reminder was given six weeks after the initial contact. Students outside the
The respondents
A total of 404 completed questionnaires were returned, but 28 of these did not fulfil the inclusion criteria, leaving 376 participants. The main characteristics of the respondents are shown in Table 1. Fifty-nine percent were female, and the predominant age was 17 years (63.5%).
Previous BLS training was common (89%) in both genders, and 73% had obtained this at school. More than half of the respondents had attended BLS courses through organizations, work, or other providers. The majority (75%)
Discussion
Early bystander CPR is one of the most significant factors for survival from OHCA.4, 22, 23 Although some recent studies have shown increased rates,24 most authors report bystander CPR rates below 50%, and the rates vary between different countries.11, 14, 25 As higher rates could increase survival, a focus on BLS training has been suggested, with a view to training those who live together with the elderly (and have the highest probability of encountering cardiac arrest), and trying to reduce
Conclusions
These findings confirm that secondary school students are an important target for efforts to increase the bystander CPR rate, at least in Norway. The motivation to help is good in this population, but barriers to start CPR become evident when the students are exposed to realistic details in potential CPR scenarios. Sufficient BLS training in school, including appropriate refresher courses and focus on known barriers to bystander CPR could strengthen the chain of survival and contribute to
Study limitations
We believe it is unlikely that the respondents differ very much from the general student population with regard to BLS training and attitude. We can, however, not rule out that the findings would have been slightly different with a higher response rate. Our study includes only students of the academically oriented “Specialisation in general studies” programme, and thus describes a subset of the population. However, this subset is representative of the majority of secondary school students in
