Abstract 350: Impact on Knowledge Retention on CPR Using a Smartphone App in Teenagers

Abstract

Cardiopulmonary arrest occurs more frequently outside the hospital, often in the presence of a teenager. Studies show that knowledge retention of basic procedures in CPR tends to decrease with time. Hypothesis: To evaluate the contribution to learning and retention of CPR techniques using a smartphone application (APP) Ressuscita. Methods: An application was developed to assist the training of CPR maneuvers. One group of students (gAPP) was trained according to the BLS principles along with the App (which was installed on the smartphones) and the group control (gCT) received the same training, without the APP. Both groups were evaluated at 3 moments, immediately after the first training (T0), 3 months (T3m) and 6 months later (T6m). Theoretical and practical evaluations were performed. After the 3-month, the gCT was received the APP (they were also able to keep the APP). The groups were matched for age and sex. Data were subjected to statistical analysis and treated as mean values and standard deviation. Shapiro-Wilk test, Mann-Whitney test and t test were used. Results: 93 teenagers were trained, with a mean age of 14 years, 49 in gAPP and 44 in gCT. The graphics show that they were homogeneous and at the end of the training presented the same grade profile in the theoretical and practical evaluation. After 3 months, the gAPP had a better knowledge and retention profile. In the practical evaluation the gAPP demonstrated a smaller reduction in score compared to those with gCT: 0.1 + 0.2 steps vs. 2.1 + 0.3 steps (p <0.001). After six months, the groups returned to the same profile of knowledge and retention. Detailing the practical evaluation, the practical skills were the most improved with the application. Conclusion: There was greater retention of knowledge, especially skills, in relation to CPR maneuvers in individuals trained with the app.
