Objective To investigate the effect of multimedia technology on disease management capability in patients with chronic obstructive pulmonary disease (COPD).Methods 77 patients with COPD were randomly divided into control group ( 38 cases ) and observation group ( 39 cases ) .The control group was educated and managed on the basis of authorization education .While the observation group was cooperated with multimedia technology for COPD education and management , on the basis of authorization education .The intervention time lasted for 3 months.And the self -management capacity and quality of life of patients in the two groups were evaluated by utilizing self-management scale and St .George Respiratory Questionnaire ( SGRQ) respectively before intervention and 3 months after intervention .Results There were no statistically significant differences in self -management capacity and SGRQ score in all subjects before intervention (all P>0.05).After 3 months of intervention,the scores of self-management capacity on symptom management , daily life management , emotional management , information management and self -efficacy of the observation group were (30.71 ±6.79)points,(42.10 ±5.92)points,(39.51 ± 5.64) points,(30.92 ±6.08) points and (31.58 ±5.43) points,respectively,which were significantly higher than those in the control group [(27.76 ±4.12) points,(39.31 ±5.11) points,(36.28 ±6.38) points,(28.39 ± 4.70)points and (29.21 ±3.3)points],and the differences were statistically significant (t=-2.299,-2.207,-2.348,-2.037,-2.299,all P<0.05).The SGRQ scores of respiratory symptoms,disease effects and motion limitation of the observation group were (40.87 ±7.27) points,(41.17 ±7.15) points and (40.48 ±5.91) points, respectively,which were significantly lower than those in the control group [( 44.7 ±8.13 ) points, ( 45.21 ± 7.60)points,(43.60 ±5.87)points],and the differences were statistically significant (t=2.199,2.395,2.321,all P<0.05).Conclusion Application of advanced digital equipment and demonstration equipment to the disease education and management of patients with COPD based on patients 'needs provides effective ways and models to patients'health education ,which promotes the establishment of patients'healthy behaviors and the management of their own diseases ,and significantly improves the patients'self-management capacity and quality of life .
