No previous studies have evaluated an oral health programme, before swallowing therapy, in patients with stroke and dysphagia in Taiwan. This randomised controlled trial evaluated the effect of an oral health programme (i.e., sputum assessment, Bass method-based tooth brushing, and tooth coating with fluoride toothpaste) before swallowing therapy. Sixty-six patients with stroke (23 female, 43 male) in our rehabilitation ward, who underwent nasogastric tube insertion, were assigned randomly to an oral care group (n = 33) and a control group (n = 33). Demographic data, oral health assessment, Functional Oral Intake Scale (FOIS) scores, Mini-Nutritional Assessment-Short Form (MNA-SF) scores, and nasogastric tube removal rates were compared between groups. We evaluated outcomes using generalised estimating equation analysis. Three weeks post-implementation, the oral care group had significant oral health improvements relative to the control group (95% CI =−2.69 to −1.25, Wald χ2 = 29.02, p < 0.001). There was no difference in the FOIS (95% CI = −0.16 to 0.89, Wald χ2 = 1.86, p > 0.05), MNA-SF (95% CI = −0.35 to 0.53, Wald χ2 =−0.17, p > 0.05), and nasogastric tube removal (p > 0.05) between groups. The oral care group had a higher, but non-significant FOIS score (3.94 vs 3.52) (p > 0.05). Routine oral health programmes implemented during stroke rehabilitation in patients with dysphagia may promote oral health and maintain oral intake.

The study aimed to illustrate the constructs and test the psychometric properties of an instrument of health literacy competencies (IOHLC) for health professionals. A multi-phase questionnaire development method was used to develop the scale. The categorization of the knowledge and practice domains achieved consensus through a modified Delphi process. To reduce the number of items, the 92-item IOHLC was psychometrically evaluated through internal consistency, Rasch modeling, and two-stage factor analysis. In total, 736 practitioners, including nurses, nurse practitioners, health educators, case managers, and dieticians completed the 92-item IOHLC online from May 2012 to January 2013. The final version of the IOHLC covered 9 knowledge items and 40 skill items containing 9 dimensions, with good model fit, and explaining 72% of total variance. All domains had acceptable internal consistency and discriminant validity. The tool in this study is the first to verify health literacy competencies rigorously. Moreover, through psychometric testing, the 49-item IOHLC demonstrates adequate reliability and validity. The IOHLC may serve as a reference for the theoretical and in-service training of Chinese-speaking individuals’ health literacy competencies.
