Effective Training Approach of Prevention and Control of COVID-19/ 新冠肺炎有效防护培训形式研究

Objective To explore the effective training approach of putting on and removing of personal protective equipment (PPE) Methods Health care workers (HCWs) were randomly divided into three groups (group 1: video training;group 2: on-site demonstration training;group 3: one-to-one practical training), training on putting on and removing of PPE was conducted After the training, three groups of HCWs were checked, training effect was evaluated Assessment on steps of putting on and removing of PPE was performed by table score and qualitative method (smearing fluorescence + powder before removing PPE to judge whether fluorescent powder was contaminated on clothes or skin) Results 169 persons were checked in each group, qualified rate of assessment of group 3was 85 21%, which was higher than 56 21 %0 of group2 and 34 3270 of group 1;among three categories of posts (nursing, medical technician and doctors), the qualified rate of assessment of nursing was the highest (71 57%,141/197), and qualified rate of medical technicians was the lowest (42 11%0, 64/152) ;in the assessment of wearing and removing of PPE, the lowest qualification rate was the tightness test of wearing medical mask, removing of one- piece protective clothes + hand hygiene were the lowest(64 69% and 60 95% respectively);there were statistically significant differences among three groups of trained HCWs, three different job posts, as well as steps of putting on and removing of PPE (all P<0 005) Qualified rate of fluorescence qualitative detection was 69 43% Conclusion One to-one training is better than on-site demonstration and video training, during the training, more attention should be paid to the tightness test of the medical protective mask, when PPE is being removed, contamination on clothes or skin should be avoided
