Abstract

Context: Beach-lifeguards are trained in AED skills at the beginning of the summer season (6 months: May – October) and have a very low prevalence of AED experience during the season. Therefore it is important to know the quality of skills performance and the retention of these skills during the holiday season. This study evaluates the retention of AED-skills by previously trained lifeguards when two methods of retraining are used.

Methods: We studied two groups at different locations in the Netherlands equipped with AEDs. Both groups received same initial BLS/AED training before summer season started. Group A of lifeguards (group A) were retrained by a certified instructor conform ERC/ILCOR-guidelines for retraining (1,2). The other group (group B) retrained themselves autonomously with a self-study poster (Figure 1). AED skills are measured directly after the course and 3, 6, 12 and 18 months later by a group of seven trained assessor. Eighteen parameters of AED skills (Table 1) have been analysed. Statistical analyses were made, using the Kruskal-Wallis test to find significant differences between the groups.

Results: In group A 134 lifeguards and in group B 72 lifeguards were retrained. There were no age differences between groups A and B. Differences between the groups were only found immediately after the course (n=134 vs. 72), after three (n=128 vs. 72) and six months (n=79 vs. 60) (Table 2). Assessment after 12 (n=31 vs. 38) and 18 months (n=20 vs. 19) showed no significant differences in BLS/AED skills.

Discussion/Implications: Comparing guided teaching with an instructor and independent learning with a poster training, tests after 12 and 18 month shows that differences between the groups were disappeared.

Lifeguards who trained themselves with the use of a validated poster had the same level as traditional trained lifeguards. The self trained lifeguards benefited from a flexible trainings program. Their resulted can be explained by the fact that they see the poster each time they are on their rescue station.

Learning Outcomes
  1. For BLS and AED skills a high retention is necessary because of the low prevalence of cardiac arrest per lifeguard.
  2. It is possible to use more flexible and autonomic training methods to train BLS and AED skills with the same effectivity.
