During the pretest of the auto drivers, 32(53.33%) of them had inadequate knowledge regarding basic life support, 26(43.33%) of them had moderately adequate knowledge and 2 (3.33%) of them had adequate knowledge. Regarding skill one of auto drivers (1.67%) had good skill, 20(33.33%) of them had average skill and 39(65%) of them had poor skill.
The present study was supported by Adelborg K (2011), who done a cross sectional study on the benefits and shortcomings of mandatory first aid and basic life support courses for learner drivers. The results showed that out of 12 questions, the average number of correct answers increased from 5.6 to 8.7 after the course (p < 0.001) and after the completion of the course, 95% or more of the participants knew how to prioritize treatment of several casualties, knew how to relieve a foreign body airway obstruction, and knew the recommended compression-ventilation ratio during CPR (p < 0.001 for all) but 64% of participants knew how to diagnose cardiac arrest and 23% of them were aware of when to activate the emergency medical services. Participants significantly increased their self-confidence in handling patients after the course (p < 0.001). It concludes that a mandatory course for learner drivers significantly improves participant's knowledge and their self-assessed skills in first aid and basic life support.
Effectiveness of Video Assisted Teaching Programme regarding Basic Life Support among auto drivers.
In the pretest, mean knowledge and skill score was13.21±3.44 and10.56±2.67. The posttest mean knowledge and skill score was 20.90±2.37 and18.45±1.73.This shows that there was a significant difference between the pretest and the posttest. The calculated 't'value for knowledge and skill were 36.25 and 42.20 which were greater than the tabulated't' value 4.05, which was significant at P≤0.05 level. Hence hypothesis H1 was retained. This reveals that the video assisted teaching programme was effective.
The present study finding was supported by Bjørshol CA et.al (2009), who conducted a randomized study on the effectiveness of personal resuscitation manikin with 24 minutes video instruction among the employees of Stavanger University Hospital, Germany. In total, 5118 employees took part in the BLS training programme. The results showed that the number of correct chest compressions increased significantly from 704(5-102) to 121 (75-150) in the pre- vs. post-training periods, respectively, P<0.01, but the number of correct MTM ventilations did not change. Self-reported BLS skills increased from 3.1 (+/-1.0) pre-training to 3.8 (+/-0.8) post-training, P=0.031. It is concluded that a personal resuscitation manikin with video instruction is a simple and less time-consuming method than instructor-led courses in preparing hospital employees in the basic handling of cardiac arrest.
The present study was supported by Bobrow (2011),who conducted a prospective study on the effectiveness of ultra-brief and brief educational videos for training lay persons responders in hands only cardio pulmonary resuscitation. Totally 336 adults without recent CPR training were randomized into 4 groups: (1) control (no training) (n=51); (2) 60-second video training (n=95); (3) 5-minute video training (n=99); and (4) 8-minute video training, including manikin practice (n=91). All subjects were tested for their ability to perform CPR during an adult OHCA scenario using a CPR-sensing manikin and Laerdal PC Skill Reporting software. Half of the trained subjects were randomly assigned to test immediately and the other half after 2-months.The results showed that twelve (23.5%) controls did not even attempt CPR, which was true of only 2 subjects (0.7%; P=0.01) from any of the experimental groups. All experimental groups had significantly higher average compression rates (closer to the recommended 100/min) than the control group (P<0.001), and all experimental groups had significantly greater average compression depth (>38 mm) than the control group (P<0.0001). It is concluded that lay persons exposed to very short hands only CPR video are moderately to attempt CPR and show superior CPR skills than untrained Lay persons.
