Study information
Scientific title
A randomised trial of high versus low intensity training in breathing techniques for breathlessness in patients with malignant lung disease: early intervention
Acronym
SOB-LC II
Study hypothesis
Three breathing training sessions at weekly intervals are more effective than a single session in reducing the breathlessness severity of patients with intra-thoracic malignancy and refractory breathlessness.
Please note that this record is related to a previously registered trial entitled "Breathlessness training: comparison of two programmes for Shortness Of Breath in Lung Cancer" (ISRCTN62865905), and can be found at http://www.isrctn.com/ISRCTN62865905.

Condition
Intrathoracic cancer
Intervention
Patients randomised to the single session training arm will be taught the four techniques of management of breathlessness (breathing control, pacing, anxiety management and relaxation) at a single session in a clinical setting appropriate to the needs of the patient by the therapist.
Patients randomised to the three session training arm will be taught the same four techniques of the management of breathlessness at a single session in a clinical setting appropriate to the needs of the patient by the therapist. This will be followed by practice and reinforcement face-to-face with the therapist on two further occasions at weekly intervals.
Both groups will receive written reinforcement in the form of information booklets plus verbal reinforcement in the format of the patients choice (CD, video or DVD) will be given to remind the patient of the techniques they have been taught. One week after the final visit, the therapist will ring the patient to see if they have remembered to practise the techniques and if they have managed to watch/listen to the reinforcement information.
The primary analysis point is a 4 weeks, but participants will be followed up until 8 weeks.

Primary outcome measure
Worst severity of breathlessness over past 24 hours measured by NRS
Secondary outcome measures
1. Breathlessness score on NRS (severity: average over last 24 hours)
2. NRS distress from breathlessness
3. NRS satisfaction with care of breathlessness
4. Global impression of changes of breathlessness
5. CRQ-SAS
6. HADS
7. Brief COPE/NRS cope
8. EQ5D
9. CIEQ-Chr
10. Number of other interventions for breathlessness during study period
11. Number of hospital admissions during study period
12. Costs associated with both comparators
13. Correlation with baseline BFI, MTQ, CIEQ-Chr scores
14. Correlation with patient programme preference
The following are measured at all time points: breathlessness severity (average over past 24 hours); distress due to, coping with, and satisfaction with the management of breathlessness; EQ5D. All secondary endpoints are measured at weeks 4 and 8 except for the global impression of change of breathlessness which is only measured at week 4.
