Effect Analysis of "Four-Step" Training and Assessment Tool in the Prevention and Control of COVID-19

To improve the ability of infection prevention and control (IPC) of medical staff during the COVID-19 epidemic period, the "four-step" mode of whole staff training and assessment was used.

During the period from March 9 to March 18, 2020, 5425 medical staff from The First Affiliated Hospital of Nanjing Medical University were selected as the objects of this study. There are four stages in the training assessment mode. The first stage is the basic assessment stage; the second stage releases the electronic version of the knowledge point manual; the third stage conducts online exercises; the fourth stage conducts the final assessment.

In the first stage, the participation rate of medical staff was 95.04%. In the fourth stage, the participation rate of medical staff was 98.01%. The average score of female medical staff in the first stage and the fourth stage was higher than that of males (P< 0.001). The average score of medical staff under 30 years old in the first stage and the fourth stage was higher than that of other age groups (P< 0.05). In the fourth stage, the correct rate of each part of exercises in the knowledge points of IPC was higher than that in the first stage (P< 0.001). In the two stages, the two parts of "COVID-19 prevention and control" and "multi-drug resistant bacteria prevention and control" had the highest accuracy, while the "disinfection and sterilization" and "infectious disease management" had the lowest accuracy (P< 0.001).

The "four-step" infection control training assessment mode has realized "full participation" and "effective training", and the level of medical staff's IPC has been significantly improved.
