Table 2. Oral care compliance (number of compliant observations vs. total observations).

GI refers to the General ICU (control group), and CI denotes the Cardiac ICU (experimental group). Data are presented as fractions (e.g., "98/241"), where the numerator indicates compliant observations for a specific oral care procedure, and the denominator represents the total observations. These fractions calculate compliance percentages to assess oral care implementation.

Time/item

Brushing teeth once every 12 hours, using a toothbrush to clean teeth and tongue for 1-2 minutes (%)

Oral and pharyngeal cleaning every 2-4 hours (%)

Prescription use of chlorhexidine oral rinse or gel (%)

Handwashing (or glove use) before procedures (%)

Elevating the head of the bed by 30° (%)

Confirming endotracheal tube cuff inflation at 25-30 before oral care (%)

Oral health assessment (%)
