Most studies show that cardiopulmonary resuscitation (CPR) skills deteriorate in the first three to six months after initial training. Automated external, defibrillator (AED) skills are retained for longer than isolated BLS skills. There is some evidence that shorter and more frequent training than standard (2 years), can potentially increase BLS competences and reduce the deterioration of expertise. In Hospital de Torrevieja we developed a program for training all staff in BLS and defibrillation, consisting of on line theory, online exam and a 2 hour practical course, every 2 years. We want to assess the knowledgements retained according to the department, and the timing of last learning undertaken. Materials and methodsWe conducted a survey regarding cardiac arrest in order to assess knowledge and subjective impression, in a total of 123 people, including physicians (P), nursing (N), clinic assistants (CA), and administrative staff (AS). We made three groups: ResultsWe show the results for the correct answer, (and timing of last training).
