Short takes: Studies on COPD, CPAP

Wednesday, April 26, 2017

When it comes to encouraging people with COPD to exercise, a mobile phone app with dialogue support works best, according to a study published in the Journal of Medical Internet Research. As part of the study, researchers reviewed three prototypes for mobile apps using different persuasive technology: dialogue support, primary task support and social support. They assessed opinions on these prototypes through 28 interviews with COPD patients, caretakers and healthcare professionals, and through 87 questionnaires completed by COPD patients. Generally, researchers found that the prototypes for mobile apps were received positively, and more specifically, they found that the prototype using dialogue support was most likely to be used or recommended by those interviewed. “Dialogue support and primary task support are considered to be both acceptable and likely to be persuasive by (COPD patients),” the study stated. “In the future, these approaches should be considered when designing apps to encourage physical activity by (COPD patients)”…Technological interventions like changes in masks, modes and pressures can help to re-initiate CPAP use, according to a study published in the Journal of Respiratory Care. Researchers found technology related problems due to mask discomfort/leaks, pressure intolerance, and residual breathing events were associated with CPAP failure in subjects seeking second opinions. But with the application of re-titration of PAP protocol (REPAP), 72% of subjects re-initiated CPAP use.
