Understanding and Practices of Oral Hygiene in the Intensive Care Units: Perspectives of Medical Staff at Two University Hospital Centers.

OBJECTIVE

This study assesses the knowledge, practices, and attitudes of medical staff in intensive care units (ICUs) regarding oral hygiene care for critically ill, bedridden patients.

MATERIAL AND METHODS

A cross-sectional study included 65 employees from the Intensive Care Units of the Sestre Milosrdnice Clinical Hospital Centre (CHC SM) and the Clinic for Anesthesiology and Intensive Care at the University Clinical Hospital Centre Zagreb (CHC ZG). A self-administered questionnaire was used to assess knowledge, methods, frequency, and attitudes towards oral care for mechanically ventilated patients. The data were examined through descriptive statistical methods, presented in terms of proportions (percentages). For the purpose of comparing the feedback across the two hospital centers and different educational backgrounds, the Chi-square and Fisher's exact tests were employed.

RESULTS

Results of a survey of 65 participants (18 from CHC SM and 47 from CHC ZG) revealed a notable disparity in oral hygiene knowledge, with graduate nurses displaying the highest proportion of adequate knowledge (100%) and regular nurses showing the least (30.3%) (p<.001). Although the execution of oral care practices did not vary significantly among the groups, graduate nurses performed oral care more frequently (80% vs. baccalaureate technicians 33.33% and nurses 57.6%, three or more times a day) and demonstrated better proficiency in both mechanical (p=.005) and chemical (p<.001) biofilm management compared to their counterparts. No significant difference was observed in the delivery of oral care to orotracheally intubated patients across different educational levels (p=.127). However, a marked difference was noted in the perception of being adequately trained for such care, with nurses feeling less prepared (12.1%, p<.001). Despite these variances, all respondents recognized the importance of oral hygiene, thus showing a strong dedication to oral health care. This study highlights variability in ICU oral hygiene practices and points to the importance of standardized care protocols and improved training for healthcare staff.
