Cardio-Pulmonary- Resuscitation (CPR) skill acquisition among adult bystander (drivers & conductors) of public transport system

Abstract

Introduction: A critical step for significant improvements in survival of outside hospital cardiac arrest (OHCA) is bystander cardiopulmonary resuscitation (b-CPR). Though ample videos of CPR demonstrations are freely available on the internet there is no evidence in literature to verify if these videos transform to practice among bystanders. Objective: To determine and compare effect of three different techniques of teaching CPR; instructional video teaching, lecture with hands on demonstration and a combination of both methods in CPR skill acquisition. Methodology: A Pre-Post study was conducted among 90 drivers and conductors of Public Transport system who were randomly assigned to Group 1(video instruction of 2 minutes duration), Group 2 (PPT lectures with Hands–on CPR demonstration on a manikin on one to one basis) and Group 3 (a mix of video, power-point presentation and practice on manikin) of 30 participants each. A pre-tested, pre designed questionnaire was used in the pre, immediate and delayed post-test containing 8 demographic questions and 27 questions regarding CPR. Results: The baseline knowledge of participants in all the 3 groups was with mean score of 11.87, 10.70 and 11.10 respectively (of the 27 questions regarding CPR).Scores of all the groups increased following intervention (23.03, 23.27 and 25.53). Retention test after one month revealed that Group 1scored 12.47, Group 2- 21.40 and Group 3 the scores were maintained at 25.53. The group which received combination methods had retained the skills learned even after 1 month. Conclusion: Combination intervention is the ideal technique of teaching CPR, where both knowledge and skills are developed and retained.
