Abstract P74: Retention of Basic Life Support Skills by Lay Rescuers after Refreshment Training
Background: The American Heart Association (AHA) recommends the training on Cardiopulmonary Resuscitation (CPR) and Automatic External Defibrillator (AED) use each two years. However, recent articles have shown a significant reduction of CPR skills after 6 months. Our training center has been training Subway Agents over the last three years. After analyzing the result of the performance in CPR maneuvers and AED handling from the subway agents, who had carried out the HeartSaver AED course of the AHA, it was set up a 90-minutes refreshment training of the skills to each 6 months, in order to maintain an acceptable level of psychomotor habilities.
Hypothesis: Retention of BLS skills increase after a half-yearly 90-minutes refreshment training.
Methods: This is an observational prospective study on the retention of BLS skills. Thirty six Subway Agents who had carried out the HeartSaver AED course and the refreshment (Group A) were compared to twenty other agents who had carried out only the course (Group B). The evaluation was performed one year after the course, consisting in a cardiopulmonary arrest simulation in a training mannequin. Three experienced and certified AHA BLS instructors conducted the test. The next criteria were valued:
Check for response;
Activate Emergency Response System and ask for an AED;
Open the airways;
Check for breathing;
Provide two rescue breaths;
Perform high-quality chest compressions;
Results: It was observed a global improvement in the skills (Group A vs Group B): Check for responsiveness (91.7% vs 85%), ask for help (63.9% vs 55%), open the airways (63.9% vs 45%), check for breathing (77.8% vs 30%), provide two rescue breaths (94.5% vs 50%), correct hand position (91,7% vs 60%), apply 30:2 ratio (94.5% vs 80%), correct frequency of compressions (58,4% vs 35%), correct pad placement (83,4 % vs 15%) and remove pads after shock (13.9% vs 15%).
Conclusion: The results suggest an improvement in BLS psychomotor skills subsequent to the refreshment training, carried out 6 months after the course. Even considering the study design limitations, the data reinforce the necessity to review the periodicity of training. Even so, it is observed the need of further research on this field.
