Pulmonary Rehabilitation

The goals of rehabilitation are to reduce the symptoms, disability, and handicap and to improve functional independence in people with lung disease. The majority of patients considered for pulmonary rehabilitation programmes will have chronic obstructive pulmonary disease:

• The rehabilitation process incorporates a programme of physical training, disease education, nutrition assessment and advice, and psychological, social, and behavioural intervention.
• Rehabilitation is provided by a multiprofessional team, with involvement of the patient's family and attention to individual needs¹.

• Although most patients will have COPD, the benefits of rehabilitation may apply to all patients with dyspnoea from other respiratory diseases. Although evidence is lacking for the efficacy of rehabilitation for patients with non-COPD causes of pulmonary impairment, many of these patients probably benefit².
• Pulmonary rehabilitation is effective for people with moderate to severe COPD. It should be offered to all people with COPD who consider themselves functionally disabled. It is not suitable for people unable to walk, who have unstable angina, or who have had a recent myocardial infarction³.
• Rehabilitation should be considered at all stages of disease progression when symptoms are present and not at a predetermined level of impairment. This would usually be MRC dyspnoea grade 3 (walks slower than contemporaries on the level because of breathlessness, or has to stop for breath when walking at own pace) or above.
• There is currently no justification for selection on the basis of age, impairment, disability, or smoking status. Some patients with serious co-morbidity such as cardiac or locomotor disability may not derive as much benefit.
• Other issues relevant to patient selection are poor motivation and the logistical factors of geography, transport, equipment usage, and the group composition.

• Pulmonary rehabilitation is effective in all settings including hospital inpatient, outpatient, the community and in the patient's home.
• Cost comparison suggests that hospital outpatient rehabilitation is currently the most efficient form of delivery¹.

• Outpatient programmes should include a minimum of 6 weeks² of physical exercise, disease education, psychological, and social intervention.
• Physical aerobic training, particularly of the lower extremities (brisk walking or cycling), is essential.
• Upper limb and strength building exercise can also be included.
• Exercise prescription should be individually assessed.
• Individual training intensity should be recorded and can be increased through the programme if appropriate and tolerated.
• Training intensity should usually be 60%-70% of maximal walking speed achieved on a shuttle walk test¹.
• However, benefit can be obtained from lower intensity training where necessary, and increased benefits can be obtained from higher intensity training (85% maximal walking speed achieved on the shuttle walk test ) when this can be achieved.
• Training frequency should involve three sessions (20-30 minutes) per week, of which at least two should be supervised.
• Supplementary oxygen during training should be provided if necessary.
• Comprehensive disease education for patient and family is an important part of overall management that can be included within the rehabilitation programme¹.
• Individual advice on physiotherapy, nutrition, occupational therapy, smoking cessation, end of life planning, and physical relationships should also be included.

• A nominated clinician with an interest in respiratory disease should be responsible for the programme. This clinician is normally responsible for medical assessment prior to entry to the programme.
• Staffing ratios will vary according to the patient characteristics, but a staff/patient ratio of 1:8 would be reasonable for the supervision of exercise classes¹.
• There should be multiprofessional involvement from local resources.
• Policies should exist for the stages of rehabilitation which include referral, assessment, selection, rehabilitation, and outcome assessment.
• Regular audit of the programme is desirable¹.
