The inclusion criteria will be as follows: (1) patients should be ≥ 50 years old; (2) patients' oral frailty should have been diagnosed with pneumonia, and (3) patients should have a Glasgow coma index of 15 points and be able to cooperate. Alternatively, the exclusion criteria will be as follows: (1) people with healthcare-related pneumonia; (2) those with head and neck cancer; or (3) those having an abnormal oral structure.
The aim of this study is to examine the effectiveness of nurse-driven oral management for improvements of oral frailty, and oral bacteria pneumonia patients with oral frailty using a randomized controlled trial (RCT) design. Hospitalized pneumonia patients (N = 90) will be randomized into three groups (oral management, oral care, and standard of care). The primary outcomes include the oral frailty measures determined by seven-item included oral hygiene, oral dryness, occlusion force, tongue-lip motor function, tongue pressure, mastication function, and swallowing function. Saliva samples were collected from the oral cavity before the bacterial culture was performed in the laboratory. Oral frailty measures and the presence of bacterial exposure were evaluated at baseline (1st day), on days 5, and at the time of discharge. The investigators will perform statistical analyses according to the intention-to-treat principle. All missing values will be imputed using the last value carry-forward method. The between-group differences will be examined using a mixed model in which group and time interaction will be included. This study finding could provide oral management strategies that could improve oral frailty and decrease oral bacteria for preventing recurrent pneumonia infection among middle-aged and older adults with pneumonia.
