A experimental design was adopted. Simple random sampling was performed to divide the subjects into the traditional teaching material-based intervention group and digital teaching material-based intervention group. A total of 51 patients with COPD and aged ≥60 years were recruited from the outpatient department of a hospital in northern Taiwan. The two groups respectively received health education through traditional paper teaching materials and digital multimedia teaching materials; 50-minute interventions were conducted once per week for 8 weeks, and measurements were taken before the interventio, 8 and 12 weeks after the intervention. Regarding the performance indicators, a paired t test and generalized estimating equation (GEE) were used to analyse differences in the COPD Assessment Test (CAT)、self-care efficiency scale for COPD and COPD knowledge scale.

The traditional teaching intervention group used the same health education content of the "E-book on Pulmonary Obstruction" printed into a paper manual for one-on-one teaching, and the same instructor provided health education guidance.

The digital teaching intervention group used a computer-downloaded "E-book on Pulmonary Obstruction" for one-on-one teaching. The subjects were also taught how to use their mobile phones to download the "E-book on Pulmonary Obstruction" and how to read it, so that they could use it on their own after returning home. The intervention time for both groups was once a week for 50 minutes each time for a total of 8 weeks. The teaching content is divided into eight themes: (1) How much do you know about pulmonary obstruction? (2) Inhalation treatment for pulmonary obstruction - Introduction to inhalers? (3) Care for pulmonary obstruction - Breathing exercise techniques? (4) Activities and exercise training? (5) Self-management methods for acute pulmonary obstruction? (6) Lung rehabilitation for pulmonary obstruction? (7) Nutritional care for pulmonary obstruction? (8) Care for pulmonary obstruction - Smoking cessation?

The CAT is an 8-item questionnaire assessing the impact of COPD on health status and daily functioning. Higher scores indicate greater disease burden. This study evaluates the effectiveness of a digital multimedia nursing education intervention in improving disease knowledge, self-care, and self-management.

Assessed using a validated COPD knowledge questionnaire to evaluate participants' understanding of disease management and self-care principles.
