Pulmonary rehabilitation including interactive 3D visualization technique, in COPD - a randomized controlled study

Abstract

<b>Background:</b> To meet new requestes among patients with Chronic Obstructive Pulmonary Disease, COPD attending pulmonary rehabilitation, PR interactive three-dimensional, 3D visualization technique was used. The program was developed to enable an increased customization of the education within the usual group setting. Using 3D techniques in education has shown some promising results but has not previously been used in patient education. <b>Aims:</b> To evaluate education by 3D technique and by conventional 2D technique, used in COPD regarding compliance to medication, exercise training and the use of health care. <b>Methods:</b> Patients with COPD included in PR at a university hospital, were cluster randomized to receive education by interactive 3D technique (n=27) or by conventional 2D technique (n=17). The PR was conducted according to international guidelines for 10 weeks. Lectures on anatomy, physiology, COPD symptoms, inhalation-, coughing-, breathing-, and exercise training techniques were included. After 6 months follow-up questions regarding compliance (yes/not completely/no) and use of health care (emergency department, inpatient health care) were answered. <b>Results:</b> At 6 months follow-up compliance to medication was 96% (3D) and 100% (2D), and compliance to exercise 68% (3D) and 51% (2D). In the 3D group one third (28%) had visited the emergency department, compared to 57% in the 2D group. In addition, 12% in the 3D group had inpatient health care visit, compared to one third in the 2D group (29%). There were no significant differences found between the groups. <b>Conclusions:</b> We conclude that educational material in interactive 3D technique can be used in PR program in COPD.
