Abstract:Objective To investigate the effectiveness of oral health education program based on information-motivation-behavioral skills model（IMB）on oral health self-efficacy, plaque index and quality of life in the patients with chronic obstructive pulmonary disease（COPD）. Methods A total of 72 COPD patients hospitalized in Hebei Provincial Hospital of Chinese Medicine from December 2021 to March 2022 were selected as the subjects and divided into control group（with routine care） and trial group（with oral health education program based on IMB model and routine care）.The self-efficacy scale for self-care（SESS）, plaque index（PI） and oral health impact profile（OHIP-14） were compared before intervention, on the day of discharge and at one month and three months after discharge between two groups. Results There were statistical differences in the time effect, intergroup effect and interaction effect in the comparison of SESS and PI between two groups（P<0.01）. There were statistical differences in time effect and interaction effect of OHIP-14（P<0.05）. The SESS and PI in trial group were significantly better than those in control group on the day of discharge and at one month and three months after discharge（P<0.05）. The quality of life in trial group was statistically superior to that in control group at the end of 3 months after discharge（P<0.05）. ConclusionIMB model-based oral health education program can reduce the plaque index of patients with COPD and improve oral health self-efficacy and quality of life, which is effect and can provide reference for clinical nurses to carry out oral health management for COPD patients.
