Study information

Scientific title

A 3-arm randomised controlled parallel group trial to determine the efficacy of pulmonary rehabilitation in moderate Chronic Obstructive Pulmonary Disease (COPD) patients in primary health care and maintenance of benefits at 2 years

Acronym

REHPOCAP

Study hypothesis

1. In patients with COPD, a long term (24 months) programme of pulmonary rehabilitation will improve the quality of life compared with patients that follow a short term duration (12 weeks) programme of pulmonary rehabilitation and compared with those who follow usual care
2. Patients included in the long term programme have less exacerbations for COPD, and a decreased number of hospital admission and inpatient stays in hospitals compared with patients with a short duration pulmonary rehabilitation programme and compared with those patients who follow usual care.
3. Patients involved in a short term pulmonary rehabilitation programme (12 weeks) improve the parameters mentioned above but the improvement is not maintained at 24 months.

Ethics approval

The trial obtained approval from the Majorca Primary Care Research Committee and from the regional Ethical Committee of Clinical Research (ref: IB370/04 PI)

Condition

Chronic Obstructive Pulmonary Disease

Intervention

Patients in the two intervention groups will receive a pulmonary rehabilitation programme of three, 90 minutes weekly sessions during 12 weeks. The sessions consist of four types of interventions:
1. Educative sessions on anatomy and physiology of respiratory system, correct use of inhalators and a brief counselling to stop smoking. This action will be carried out in weeks 1, 6 and 12.
2. Respiratory Physiotherapy (self conscious breathing control, diaphragmatic breathing control, chest wall exercises, and abdominal muscles wall work) during weeks 1, 6 and 12.
3. Low intensity peripheral muscle training. It consists on abdominal and upper and lower limbs exercises, shoulder and arms circling, raising weights and other exercises. The program has been described by (Clark CJ 1996) and has been used in other clinical trials (Normandin EA 2002, Foglio K 1999). Each exercise is repeated between 8-10 times during 45 minutes. It takes one and half hours to complete exercise with small breaks. The program has 12 weeks duration.
4. Patients will be asked to practice a low level home-based exercise program adapted to individual characteristics. Compliance with home-based programme will be assessed every two weeks with the patient and registered in a spread-sheet. Interventions will be carried out in groups of 8-10 persons. A primary care nurse will carry out the educative intervention and the exercises programme by two physiotherapists in two Primary Care Physiotherapy Units. Nurses will be trained in the educative intervention and group dynamic. In order to standarise physiotherapist intervention, a 7 days tuition programme will be developed.
5. After completing the 12 weeks pulmonary rehabilitation programme, each patient will be included in the activities of the initially assigned group RHBM, or RHB.
5.1. patients in group RHB will follow their usual care with his physician and nurse.
5.2. patients in group RHBM will follow a weekly session of maintenance till the end of the programme at 24 months.
5.3. patients in control group will follow their usual care with their physician and nurse from the inception.

Primary outcome measures

Quality of life:
Assessed by the Spanish validated version of the Chronic Respiratory Questionnaire (CRQ) a 20 items scale, administered by an interviewer, designed for COPD patients. Each item is graded on 7-point likert scale. It includes four domains: dyspnoea (5 items), fatigue (4 items), emotional function (7 items) and mastery (4 items). It scores each dimension summing the punctuation of each item or through items average. The clinical repercussion of changes in the punctuation of CRQ after a therapeutic intervention (minimal important difference - MDCI) is 0.5 per item and 10 global scoring, a change of 2.5 in dyspnoea domain, 2 for fatigue and mastery and 3.5 for emotional function (Reardon J 1994). The questionnaire was adapted and validated by Güell et al (Güell R et al. Eur Respir J 1998; 11: 55-60.), showing good psychometric properties, high reliability and sensitivity to changes.

Secondary outcome measures

1. The 6-min-walking test:
Conducted along a flat corridor during 25 minutes. Each patient will be instructed and receive standarised encouragement to walk from one end to the other, covering as much ground as possible during the allotted time, as recomended by the American Thoracic Society.
2. Patients will rate their level of dyspnoea in daily activities through the Dyspnoea Index (Borg scale):
A 10cm visual analogue scale bounded by the descriptors 'no shortness of breath at all' and 'maximum shortness of breath' and using the Medical Research Council (MRC) scale which specifies eight levels of dyspnoea.
3. Lung function testing:
Including forced spirometry with bronchodilator test with a Datospir 120 spirometer following Spanish Society of Pneumology and Thoracic Surgery (SEPAR) recommendations for the values of FVC, FEV1, FEV1/FVC and Finite Element Model (FEM).
4. Number of hospital admissions and length of stay:
By patient information. This information will be validated through hospital medical records.
5. Number of severe exacerbations:
Defined as episodes of either dyspnoea or dry or productive cough, whether sputum was purulent or not, treated with oral corticoids and/or antibiotics requiring hospital admission.
