Objective To investigate the clinical nurses' non-standard behaviors in using marks.Methods The covert observation method was used in this study.And the clinical nurses' behaviors in using marks were observed and investigated based on the pre-designed structured observation checklist.Results A total of 662 non-standard behaviors in using marks were found from 142 person-time among clinical nurses.The occurrence frequency of touching the outside of masks (28.55％) was the highest in all non-standard behaviors,and followed by putting used masks into pockets directly(26.13％),no washing hands or using hand sanitizer after removing masks (20.69％),no washing hands before removing masks (14.80％).The occurrence frequency of non-standard behaviors among the special unit nurses was less than that among the general ward nurses,especially no washing hands before removing masks and putting used masks into pockets directly,and the difference was statistically significant (P ＜ 0.05).There was no statstically significant overall difference among different working days and working hours on the clinical nurses' non-standard behaviors in using marks (P ＞ 0.05),but the differences were statistically significant in touching the outside of masks and no washing hands before removing masks among different working days and working hours (P ＜ 0.05).Concltsions There are serious non-standard behaviors in using masks among clinical nurses,and the nurse managers should pay more attention on the management in using masks.
