Objective: To study the application of health belief mode in elderly patients with stable chronic obstructive pulmonary disease (COPD) and its nursing effect. Methods: From April 2018 to April 2019, 76 elderly patients with COPD stable stage were selected and randomly divided into an observation group and a control group, each with 38 cases. The control group received routine nursing, the observation group implemented health belief mode nursing based on conventional nursing. The nursing effects were compared between the two groups. Results: After nursing, self-care ability score of the observation group’s was higher than the control group (P<0.05); in terms of rehabilitation compliance rate, the observation group was higher than that of the control group, the difference was statistically significant (94.74% vs 76.32%, P<0.05). Conclusion: Implementing health belief mode in the care of elderly patients with COPD stable stage can improve patients’ self-care ability, and the compliance in rehabilitation, which is worth promoting.
