摘要:Oral mucosa pressure ulcers (PUs) can result in frequent pain and discomfort, and have negative effects on quality of life. We aimed to examine attitude, barriers/facilitators of oral mucosa PU prevention, the ability to differentiate oral mucosa PU, and to identify factors influencing PU prevention performance intention. This was a cross-sectional descriptive study of 112 nurses in seven tertiary hospitals and three secondary hospitals. The data collection period was from August to December 2018. For data analysis, descriptive statistics, t-test, ANOVA, Pearson’s correlation coefficient, and multiple regression were used. The mean score of attitudes toward oral mucosa PU prevention was 3.74 ± 0.39. Barriers to oral mucosa PU prevention were 5.65 ± 1.66, and facilitators were 5.35 ± 1.34. The mean correct answer rate of visual differentiation ability was 13%. The factors affecting intention to perform oral mucosa PU prevention were facilitators of oral mucosa PU prevention (β = 0.32, p = 0.001) and attitude (β = 0.26, p = 0.005). To increase intention to perform oral mucosa PU prevention, positive attitudes and enhanced facilitators should be encouraged. Therefore, standardized guidelines and strategies, such as educational opportunities and allocation of resources and personnel focused on oral mucosa PU prevention, need to be provided.
