Abstract

Objective: To understand the implementation of VAE (Ventilator-associated Event) preventive measures and their influencing factors in ICU of tertiary A-level hospitals in the Beijing-Tianjin-Hebei region of China.
Methods: A self-designed web-based questionnaire was used to conduct a cross-sectional survey of 32 ICUs in Beijing, Tianjin, and Hebei to investigate the implementation of ventilator-related event prevention measures, and t-tests and chi-square tests were performed on the collected data.
Results: A total of 32 ICUs responded to the questionnaire. The results showed that the recommended precautions were not standardized. Nearly half of ICUs did not perform oral care with recommended frequency (more than 3 times a day or more), and only eight of all ICUs used toothbrushes. The implementation rate of daily SAT and SBT was low, and only more than half of ICUs chose dexmedetomidine as the primary sedative medication; We found that nurse bed and MV patient ratio were significantly associated with SAT and oral care frequency when the relationship between the characteristics of ICU and the implementation of VAE preventive measures was analyzed.
Conclusions: The questionnaire shows that it is necessary to improve the compliance of daily SAT and SBT and the frequency of oral care and brushing and to place sufficient medical staff to increase the compliance of these VAE precautions.
