Brief Summary

Title: Out-of-hospital cardiorespiratory arrest and learning cardiopulmonary resuscitation in the school setting: evidence synthesis. CPR-KNOW PROYECT. Background: The high incidence, associated morbidity and mortality, and the great individual, social and economic impact of out-of-hospital cardiorespiratory arrest (OHCA) make it a priority for all health systems worldwide. To increase the rates of potential first responders who act appropriately, applying basic life support (BLS) measures in the OHCA, the European Resuscitation Council includes among its latest recommendations the training of all school children through the "Kids Save Lives" initiative. Objectives: to determine, through a randomized clinical trial, the effectiveness of two training strategies for increasing theoretical and practical knowledge of BLS in schoolchildren and adolescents. Methodology: To evaluate the effectiveness of two (Cardiopulmonary Resuscitation) CPR teaching interventions in improving the following outcome variables: theoretical knowledge and practical skills, CPR quality; as well as its relationship with the anthropometric, sociodemographic and physical condition variables of the schoolers.

  • Intervention group 1 (IG1): a 2-hour theoretical-practical session on the BLS sequence taught by a Nursing professional performing the practice with a mannequin. Instructor/school ratio: 1/25 for the theoretical session and a school/mannequin ratio: 2-3/1.
  • Intervention group 2 (IG2): a session with short video (approximately 5-10 min) and other teaching resources (puzzle), without practice on a mannequin. Video/school ratio: 1/25 and a school/teaching resource (puzzle) ratio: 1/1.

Outcome Measures

Primary Outcomes (3)

  • Theoretical CPR Knowledge

    Theoretical CPR Knowledge measured by a questionnaire.

    On the same day as the intervention, before (pre-intervention) and immediately after this (post-intervention) and follow-up (8 months later)

  • CPR Practice Skills

    CPR Practice Skills measured with a checklist

    On the same day as the intervention immediately after this (post-intervention) and follow-up (8 months later)

  • Quality of CRP

    Quality of CPR measured by Little-Anne Mannequin.

    On the same day as the intervention, immediately after this (post-intervention) and follow-up (8 months later)

Other Outcomes (7)

  • Anthropometry: weight

    Immediately post-intervention

  • Anthropometry: height

    Immediately post-intervention

  • Anthropometry: BMI

    Immediately post-intervention

  • +4 more other outcomes

Study Arms (2)

Traditional CPR teaching

ACTIVE COMPARATOR

A 2-hour session of conventional theoretical-practical training with a mannequin, about the BLS sequence to follow in a CPR-OHCA, adapted to the age of schoolchildren, and taught by nursing professionals. Theoretical-practical training on the operation of the semi-automatic defibrillator.

Other: Cardiopulmonary Resuscitation Teaching Intervention in Children

Video and teaching material

EXPERIMENTAL

A short video (5min) in which the basic sequence of BLS to follow in a CPR-OHCA is explained, accompanied by a puzzle adapted to the age of the children in which the BLS sequence is reflected, but without practice on a mannequin. Theoretical training included in the video about the operation of the semi-automatic defibrillator.

Other: Cardiopulmonary Resuscitation Teaching Intervention in Children

Interventions

Comparation of two type of Cardiopulmonary Resuscitation Teaching Intervention in Children: traditional teaching vs video with puzzle.
