A breathing retraining exercise programme, incorporating a training DVD and accompanying booklet, achieved similar improvements in quality of life scores as conventional face to face training in patients with asthma, in a UK study.

A total of 655 asthma patients, aged 16-70 years, were recruited from 34 general practices. There were broad entry criteria with smokers included and no requirement for demonstrated airflow reversibility, although those with COPD and an FEV1 < 60% predicted were excluded. All patients had had asthma diagnosed by a physician, had received inhaler therapy in the past year and had Asthma Quality of Life Questionnaire (AQLQ ) scores of  5.5 or less.

Subjects were randomised to three groups: 262 to standard therapy, 132 to face to face physiotherapist breathing retraining sessions and 261 to the DVD and booklet. (This intervention was based on a breathing retraining programme taught by physiotherapists and shown to be effective in poorly controlled asthma.) As far as possible, treatment group was blinded to the researchers and patients were asked not to discuss their treatment.

The main outcome was the AQLQ score at 12 months. Secondary outcomes included patient-reported and physiological measures of asthma control, patient acceptability and healthcare costs.

AQLQ scores were significantly higher in the DVD plus booklet group compared with the usual care group; mean 5.40 vs 5.12, adjusted mean difference 0.28 (95% CI: 0.11-0.44) and in the face to face treatment group mean 5.33 compared with the usual care group, adjusted mean difference 0.24 (95% CI: 0.04-0.44). There was no significant difference in AQLQ scores between the DVD plus booklet group and the face to face breathing retraining group.

There were no significant differences in secondary outcomes between the groups apart from a small but significant improvement in the HADS score for depression in the DVD plus booklet group. The latter group also demonstrated a non-significant tendency to fewer asthma attacks compared with the usual care group. Adverse effects in the treatment arms were not significant and the three deaths which occurred  (one in the DVD plus booklet group and two in the usual care group) were thought not to be study related.

The BTS/SIGN asthma guideline indicates that there is good evidence for using breathing exercise programmes but from a practice perspective these are often difficult to access and costly in therapist time.

This was the largest trial of breathing retraining in asthma to date to use a pragmatic randomised controlled trial design. It shows that advice and training using a DVD and booklet offers comparable clinical benefits to face to face sessions by physiotherapists.

This self-management approach offers a practical prospect of improving care for our asthma patients more conveniently and inexpensively.
