Analysis of factors influencing the acquisition of basic life support knowledge among standardized training trainees

Abstract

Cardiopulmonary resuscitation (CPR) significantly impacts the treatment success of cardiac arrest patients and serves as a simple and practical basic life support (BLS) skill. However, there is a lack of analysis regarding factors influencing BLS knowledge acquisition by trainees after training. In this study, we analyzed and explored this issue based on assessments of 385 trainees newly enrolled in standardized residency training at West China Hospital, Sichuan University in 2022. They came from various medical institutions and underwent a 3-day systematic training in basic life support skills. At the end of the training, their knowledge acquisition was analyzed through an examination. The results indicated that BLS knowledge acquisition scores among these 385 resident trainees were not significantly different in age, gender, education, length of service, professional title, or teaching style preference. However, two factors demonstrated significant influence: the trainees’ profession type (F = 39.45, p < 0.001) and previous BLS training (t = −4.42, p < 0.001). Linear regression analysis indicated that technicians had a 12% lower BLS accuracy compared to doctors (β = −0.12, p < 0.001), while those who had received prior BLS training exhibited an 8% higher accuracy compared to those who had not (β = 0.08, p < 0.001). Thus, it is important to focus on enhancing BLS knowledge and skills among technician trainees in residency training. Additionally, increased standardization in BLS training can prove beneficial in improving trainees’ comprehension and mastery of BLS knowledge.
