Evaluation of a tablet-based instruction of breathing technique in patients with COPD

Our tablet computer-assisted educational aid did not provide an improvement over the traditional method for teaching breathing techniques to elderly patients with COPD. The results only showed an immediate effect on the self-efficacy of the breathing technique. The elderly did not use the tablet computer actively and the research was conducted without intervention after discharge, which may be a reason why the effect did not last. Further research to evaluate the effectiveness of such a strategy for the elderly is needed in the future.
