Tablet computers to support outpatient pulmonary rehabilitation in patients with COPD

BACKGROUND: A minicomputer (tablet) with instructions and a training diary has the potential of facilitating adherence to pulmonary rehabilitation (PR). OBJECTIVE: To evaluate the effect of adding a tablet to a classic outpatient PR programme for COPD patients. METHODS: A total of 115 patients participated in a 7- to 10-week outpatient PR programme in groups of 10–12 individuals. Half of the groups were assigned to PR plus a tablet (tablet group) and the other groups were assigned to PR only (controls). Primary effect parameters were endurance shuttle walk time (ESWT) and disease-specific health status (COPD Assessment Test=CAT). RESULTS: The change in ESWT was significantly better in the control group (mean 167 sec) compared with the tablet group (mean 51 sec) (p<0.01), whereas the change in CAT score did not differ significantly between the two groups (−0.6 vs. −2.3) (p=0.17). CONCLUSIONS: Compared with usual PR, no significant improvements were seen in the group equipped with the tablet after 7–10 weeks of rehabilitation. Future studies should focus on long-term effects.
