A Virtual Reality-Supported Intervention for Pulmonary Rehabilitation of Patients With Chronic Obstructive Pulmonary Disease: Mixed Methods Study.

BACKGROUND

The uptake of traditional pulmonary rehabilitation classes by patients with chronic obstructive pulmonary disease (COPD) is poor because of personal factors that prevent accessibility to the venue. Therefore, there is a need for innovative methods of pulmonary rehabilitation, and virtual reality (VR) could be a promising technology for patients with COPD to access services remotely.

OBJECTIVE

This study aimed to investigate whether VR improves compliance with pulmonary rehabilitation among patients with COPD, a particularly vulnerable patient group (Medical Research Council [MRC] 4 or 5), and whether VR provides a credible alternative to traditional pulmonary rehabilitation programs.

METHODS

This was an 8-week patient trial using an innovative VR pulmonary rehabilitation program. A purposive sample of 10 patients with COPD graded MRC 4 or 5 and registered at a selected health care center and a hospital in Cumbria, United Kingdom, were included. Qualitative (focus groups and interviews) data were collected, and to further support the qualitative findings, quantitative data (self-report patient surveys) were gathered before and after the 8-week trial. The 5 self-reported surveys included the Patient Activation Measure, Generalized Anxiety Disorder-7, Patient Health Questionnaire-9, Short Physical Performance Battery, and the Edmonton Frail Scale.

RESULTS

In a thematic analysis of the qualitative data, 11 themes emerged specific to delivering pulmonary rehabilitation using VR. The quantitative data further support the qualitative findings by revealing significant improvements in all physical measures.

CONCLUSIONS

Overall, this study demonstrates how remotely supervised VR-based pulmonary rehabilitation could help to overcome current issues and limitations associated with providing this service to patients with COPD at scale.
