HYPOTHESIS:The study purpose is to evaluate the effectiveness of a structured pursed-lips breathing (PLB) protocol taught via real-time interactive telecommunication with a home computer using the lnternet and Skype software in veterans with chronic obstructive pulmonary disease (COPD. The primary hypothesis is veterans with COPD and dyspnea on exertion who receive a PLB educational intervention taught via weekly interactive telecommunication over a 4-week period will have greater reduction of exertional dyspnea compared to those who receive the PLB educational intervention with no weekly interactive sessions.
RESEARCH PLAN: An experimental two- group design is used. All subjects receive a brief 5 - 10 minute one-on-one PLB educational session. Subjects are then randomized to either the intervention group or the control group. The intervention group receives 4 weekly interactive group sessions with the health educator (principal investigator)via computer. A free software program known as Skype allows synchronous video and audio interaction. The comparison group receives only the brief PLB educational session with no weekly follow-up.
RESULTS: At end of 4 weeks, the intervention group had significantly lower dyspnea intensity scores (group X time interaction F = 6.69, p = 0.02) and significantly higher social support scores (group x time interaction F = 4.34, p = 0.058).
CLINICAL SIGNIFICANCE: Skype is a viable means for providing patient education. A structured PLB protocol provides significant differences in exertional dyspnea over time. A structured PLB protocol plus Skype showed significant reduction in patients' sense of dyspnea intensity and increased social support scores.
