Evaluation of retention of knowledge and skills imparted to first-year medical students through basic life support training

摘要

Poor awareness among medical graduates about basic life support (BLS) is a matter of great concern. The presence of a trained rescuer is the key determinant of ultimate survival from life-threatening emergencies. To achieve this goal, early exposure to such life-saving skills is the right decision to foster these skills for medical students, which can be reenforced in succeeding years. Forty-two first-year medical students participated in this study. The entire procedure consisted of faculty training, assessment of knowledge of students by a pretest questionnaire, a lecture, a demonstration, and hands-on training using a mannequin (with special emphasis on the site, depth, rate, and sustainment of uninterrupted chest compressions). Posttest 1 was conducted to assess the knowledge gained. The retention of knowledge and skills in the second year was evaluated by posttest 2 and directly observed procedural skills, respectively. Student feedback was collected on five-point Likert scale. Analysis using a Freidman test indicated the mean rank for posttest 1 (2.81) to be significantly higher than the pretest (1.26), indicating a gain in knowledge. The mean rank for posttest 2 (1.93) was lower than for posttest 1 (2.81) but was significantly higher compared with the pretest (1.26), indicating a significant retention of knowledge during the second year. Directly observed procedural skill evaluation showed that 7% students could perform all the seven steps correctly and that 74% students could perform three or more steps correctly, signifying a good retention of skill. Two students taught BLS skills to their family members as well. The results of this study suggest that the program provides students with sound basic knowledge and adequate practical skills in BLS.
