The purpose of this study was to identify the characteristics of the infection prevention behavior of nurses in relation to tracheal aspiration procedures in the intensive care unit (ICU), where many patients attached to mechanical ventilators are admitted and the risk of healthcare-associated infection is high, and to obtain suggestions in regard to the education that is needed.
The subjects were 42 ICU nurses, and we observed their actions during 126 tracheal aspiration procedures, conducted a bacteriological survey of the environment around 11 patients, and conducted a survey of awareness by means of a questionnaire, and of attitude by self-report.
The result of the observation survey showed a high rate of proper glove use, but the rate of proper performance of hand hygiene was low. A tendency was seen for the hand hygiene performance rate to be higher after aspiration procedures than before aspiration procedures. Also, 15.9% of the subjects were able to properly perform hand hygiene from before the start of the aspiration procedure to its conclusion and perform glove handling as a single continuous series of actions. Preventing infection by performing all of the individual actions necessitates acquiring the skill of being able to perform them as a continuous series of actions.
Furthermore, even when the nurses predicted contamination, they did not go so far as to clean the site. We obtained suggestions in regard to education support that will enable feedback regarding what nurses themselves can do and enable them to review their own behavior in relation to events that they are aware of.
