What is Pulmonary Rehabilitation?

      “…a multidisciplinary programme of care for
    patients with chronic respiratory impairment that
     is individually tailored and designed to optimise
      each patient’s physical and social performance
                   and autonomy.” (NICE)

Why is it important?

• COPD causes 30,000 deaths per year and leads to extensive morbidity. It
   incurs massive costs in relation to hospital admissions, incurring nearly 6
   times as many bed days of inpatient care as asthma.

• Interventions which improve quality of life and level of functioning are
   important since few interventions except smoking cessation affect disease

Benefits of Pulmonary Rehabilitation

• Break out of the “emotional straightjacket”

• Improved exercise capacity (A)
• Improved health-related quality of life (A)
• Reduced hospitalisations and length of stay (A)
• Reduced anxiety and depression associated with COPD (A)

• ? Increased survival (ACCP)

• Benefits probably extend well beyond the period of rehab, especially if
   exercise training is maintained at home. (GOLD)

In what settings?

• Effective in inpatient, outpatient and community settings and possibly at

• Should be held at times that suit patients in buildings that are easy to
    access with appropriate access for those with disabilities.

Who is it for?

• All disease severities (but may not benefit if unable to walk)

• …where SYMPTOMS AND DISABILITY are present (usually MRC grade 3)

• No justification for selection on basis of age, impairment, disability, smoking
   status or oxygen use

• Enrolment on a smoking cessation programme a pre-requisite for inclusion?

• Continuing smokers may be less likely to complete

• Contra-indicated if recent MI/ unstable angina

Course Content and Duration

• The longer the better but usually 6-12 weeks (NICE). Minimum effective
   length 8 weeks (GOLD)

• Diagnostic assessment

• Baseline and outcome assessments: exercise capacity (shuttle walk),
   disability/health status (questionnaire)

• Interventions : exercise training, educational, psychological, nutritional

Exercise Training: Frequency, Intensity and Duration

• Daily to weekly (x3/week)

• 10-45 mins (? < 20 mins insufficient to elicit a training effect)

• 50% intensity (50% peak oxygen consumption) upto maximum

• Optimum duration not determined but usually 4-10 weeks (longer courses
   show greater effects)

Exercise Training: Which muscle groups?

• Lower limb training improves exercise tolerance though no effect on
   measured lung function

• DOESN’T HAVE TO BE HI TECH- corridor training common

• Upper limb training improves arm strength and reduces ventilatory demand

• Respiratory muscle training may influence endurance and dyspnoea but
   evidence is conflicting

Psychological components

• COPD is associated with anxiety and depressive symptoms which may
   interfere with activities of daily living (ADL’s)

• Evidence lacking for short term psychological interventions as a single
   therapeutic modality but longer term interventions may be beneficial

• Expert opinion supports the use of educational and psychological
   interventions in pulmonary rehab programmes

• Typical goals: address depression/anxiety, teach relaxation skills, discuss
   relevant issues such as sexuality, family and work relationships

• The most positive evidence relates to adherence intervention and cognitive

09/2004                           Dr. Alastair Jackson

• Usually in group classes. Evidence lacking for educational interventions in
   isolation though benefits as part of a multidisciplinary approach widely

• Wide variety of topics: A+P, pathology, breathing retraining, nutrition,
   medication regimens and mechanisms, importance of exercise, managing
   dyspnoea, self-management, travel advice, safe oxygen use, advance
   directives and end of life decisions where appropriate

09/2004                          Dr. Alastair Jackson
Nutritional counselling

• Both overweight and underweight can be a problem

• 25% of patients with moderate to severe COPD show a reduction in BMI
   which is an independent risk factor for mortality in COPD

• Reasons for difficulty eating should be explored: poor dentition, dyspnoea
   whilst eating

• Advise frequent small meals

09/2004                         Dr. Alastair Jackson

• Costs of rehab per QALY gained estimated at £2,000-£8,000

• Overall, pulmonary rehab is probably cost saving (probability 0.64) and
   improves quality of life
