Effectiveness of online versus in-person structured training program on arterial blood gas, electrolytes, and ventilatory management of critically ill patients

Abstract

Background: Due to the risk of viral transmission during in-person training, a shift toward online platforms is imperative in the current pandemic. Therefore, we compared the effectiveness of an in-person interactive course with a structurally similar online course designed to improve cognitive skills among clinical health professionals in arterial blood gas analysis, management of electrolyte imbalances, and approaches to mechanical ventilation in critically ill patients. Methods: In an observational, outcome assessor-blinded, cohort trial, group A included participants enrolled prospectively in an online course, while group B included those who took part in an in-person course (retrospective arm). The primary objective was comparison of cognitive skills through a pre and post-test questionnaire. Statistical analysis was performed using Student t-test. Results: In total, 435 participants were analyzed in group A, while 99 participants were evaluated in group B. The mean pre-test score was 9.48±2.75 and 10.76±2.42, while the mean post-test score was 11.94±1.90 (passing rate, 64.6%) and 12.53±1.63 (passing rate, 73.3%) in groups A and B, respectively. Group B scored significantly higher in both pre-test (P=0.001) and post-test evaluations (P=0.004). The improvement in post-test score was significantly greater (P=0.001) in group A (2.46±2.22) compared to group B (1.77±1.76). The medical specialties fared better in group B, while surgical specialties scored higher in group A. The pre-test vs. post-test scores exhibited a moderate correlation in both groups (P<0.001). The feedback survey showed a Likert score >3.5 for most points in both groups. Conclusions: The online teaching module exhibited a significant benefit in terms of participant sensitization and knowledge sharing.
