CPR Training in Students to Increase Bystander Intervention in Out-of-hospital Cardiac Arrest.

The overall aim of this thesis is to identify the factors that may affect 13 year old students' acquisition of CPR skills and their willingness to act. The primary hypothesis is that the training method (intervention) influences the participants' acquisition of practical CPR skills and willingness to intervene.

The study used a cluster randomized design, based on a randomization list generated by an independent statistician. The school classes were randomly assigned to different CPR training interventions.

A strategic sample, where invitation to participate in the study was sent to the headmasters of all council schools, with seventh grade students, in two Swedish municipalities (140,000). Thus, the sample consists of participants with different cultural as well as socio-economic background. Eighteen of 24 schools agreed to participate. Four schools did not respond and two schools had a routine to offer CPR education only for grade nine (all six schools from the same municipality). The eighteen schools who agreed to participate consisted of sixty-eight classes with 1547 students.

Prior to study participation, students and their guardians obtained a letter with study information. Study participation of the individual students was voluntary and all participants gave an oral informed consent.

Inclusion criteria: seventh grade student in one of the participating schools. Exclusion criteria: student does not want to participate, student with a physical handicap that limited the physical performance, classes of students with development disabilities (these classes are age-integrated and have fewer students per class).

Study Overview

• Status: Completed
• Conditions: Coping Skills
• Intervention / Treatment: Other: CPR training; Other: web course

Detailed Description

The main interventions were app or DVD-based education. In addition to the main intervention some classes were randomized to various additional interventions; web-course, visits of elite athletes, practical test, reflection and AED training. All CPR education was performed in accordance with the ERC guidelines of 2010. Training was given to the entire class together. The classes consisted of 14-29 students. All participants in all intervention groups used an individual training manikin, MiniAnne, during the training. The schools were allowed to keep the training manikins after the end of study. Ten teachers were previous CPR instructors and another 19 teachers received a five hours education to become CPR instructor. All teachers obtained individual oral and written instructions about each class randomized intervention method and written bullet points about how the course would be implemented, to ensure that they were up to date with present guidelines and training. The teachers acted as facilitators; they introduced the lesson, gave advice on the fly, answered questions and completed the course.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The total score of the modified Cardiff test at six months	The total score was calculated by adding the individual scores of the 12 different categories (check responsiveness by talking, check responsiveness by shaking, open the airway, checks respiration, dials 112, compression/ventilation ratio, hand-position during compression, average compression depth, total compression counted, average ventilation volume, total ventilation counted, total hands-off time) assessed by the practical test.	At six months follow-up test

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The total score of the modified Cardiff test directly after training	The total score was calculated by adding the individual scores of the 12 different categories (check responsiveness by talking, check responsiveness by shaking, open the airway, checks respiration, dials 112, compression/ventilation ratio, hand-position during compression, average compression depth, total compression counted, average ventilation volume, total ventilation counted, total hands-off time) assessed by the practical test.	Directly after training (on the day of intervention)
Self-reported willingness to make a lifesaving intervention	Self-reported willingness to make a lifesaving intervention was measured by a questionnaire	Both directly after training (on the day of intervention) and at six months
Knowledge about stroke, acute myocardial infarction and living habits	Theoretical knowledge about acute myocardial infarction and living habits was measured by a questionnaire	Both directly after training (on the day of intervention) and at six months
