Impact Of Multimodal Strategies To Reduce Multidrug-Resistant Organisms In Surgical Intensive Care Units: Knowledge, Practices And Transmission: A Quasi-Experimental Study

Aim: This study examined the effects of multimodal strategies on knowledge and practices in preventing multidrug-resistant organism (MDRO) transmission among healthcare personnel (HCP), and to investigate MDRO transmission in two surgical intensive care units (SICUs).Design: A quasi-experimental study with a one-group pretest-posttest design.Methods: We recruited 62 HCP. Data were collected during 2017-2019. Multimodal strategies, including training, educational and reminder posters, an educational YouTube channel, champions and feedback, were used to enhance knowledge and practices. Data were analysed using Wilcoxon signed-rank test and chi-square test.Results: After the intervention, median knowledge scores increased from 16.0 to 17.0 (p = .001), and overall correct MDRO prevention practices increased from 76.6% to 94.0% (p < .001). The MDRO transmission rate decreased from 25% to 0% (p < .001).Conclusion: The findings indicate that multimodal strategies could enhance knowledge and practices for preventing MDRO transmission among HCP and could reduce the MDRO transmission rate in SICUs.
