Dyspnea related to chronic pulmonary disorders is difficult to manage. In this single-arm study, we evaluated feasibility and potential efficacy of a self-care breath training program to reduce dyspnea that persists despite standard treatments in patients with chronic lung disease.
Adult patients with a chronic pulmonary disorder and stable moderate dyspnea received one 30-min training on specific breathing techniques, followed by audio-guided at-home practice 15 min twice daily for 6 wk, supported with weekly telephone monitoring/coaching. The feasibility endpoints, Baseline and Transition Dyspnea Indexes, 6-min walk test, Hospital Anxiety and Depression Scale, and oxygen saturation at rest and exercise were evaluated at baseline and wk 6.
Of the 23 patients enrolled over 2 yr, 19 completed the study. A majority (74%; 95% CI, 49%-91%) completed at least 75% of the home practice sessions. Significant objective improvements in physical performance, defined as distance walked, were observed after 6 wk of intervention. On average, patients walked significantly further in the 6-min walk test (59 ft; 95% CI, 18-99; P = .007). In addition, 53% reported clinically significant (20%, defined a priori) subjective improvement in the Transition Dyspnea Index, although the difference was not statistically significant (0.7; 95% CI, −0.8 to 2.3; P = .3). No significant differences were seen in the Hospital Anxiety and Depression Scale or oxygen saturation.
A low-burden, low-cost, self-care breath training program improved distance walked by patients with chronic dyspnea after 6 wk of home practice. Promising data suggest that a randomized trial of this breath training program is warranted.
We have developed a low-cost, low-burden, and flexible self-care tool for patients to do breathing exercises at home. Patients showed significant improvement in physical performance after 6 wk of home practice with this innovative breath training program in a prospective clinical trial we conducted.
