Maintenance Schedules Following Pulmonary Rehabilitation
Recruitment status was: Active, not recruiting
Chronic obstructive pulmonary disease (COPD), a preventable and treatable condition, is a major healthcare problem with huge human and economic costs. It affects 3 million people, results in 1.4 million consultations, causes 30,000 deaths, and costs £800M per year in the UK. Considerable research expenditure is devoted to finding new and expensive interventions. However pulmonary rehabilitation (PR) is an available therapeutic option with good evidence of benefit for patients in terms of quality of life and daily functioning.
The primary objective of the study is to evaluate the effectiveness and cost effectiveness of the addition of a maintenance programme following pulmonary rehabilitation in patients with COPD when compared to standard care.
The secondary objective is to identify baseline characteristics that will predict improvement in pulmonary rehabilitation programmes and adherence to maintenance strategies. By measuring a series of demographic, clinical, physiological, psychological and biochemical parameters the researchers hope to be able to predict those patients who are likely to receive the greatest benefit from pulmonary rehabilitation.
An additional objective will be to prepare a detailed maintenance programme manual. This will be available to other centres providing pulmonary rehabilitation at the conclusion of the study

Intervention with exercise management
Behavioral: Pulmonary Intervention
Maintenance programme of 2 hours duration, every 3 months. During the first hour patients will describe the extent to which they have been able to continue with their exercises at home on an individual basis and ways of enhancing adherence to this training will be discussed. Positive re-enforcement will be provided. Patients with suspected depression or social isolation will be referred to their GP for additional management. Patients will be advised on dyspnoea management strategies, especially controlled breathing combined with supervised activity exertion on activities relevant to their daily living. This will be followed by 1 hour of supervised strength and endurance training including walking, cycling, standing from sitting, arm exercises using dumbbells and step-ups. Patients will receive a written report on their progress by their physician and copied to their GP. This will be in addition to the standard advice given to the control group.
No Intervention: Control Group
Patients will receive the standard advice to undertake strength and endurance exercises at home and invitation to attend the Norwich Breath Easy Group
Patients will be stratified according to whether the initial programme took place in the outpatient hospital or community setting
This will be a randomised, controlled, parallel study of a maintenance pulmonary rehabilitation (PR) programme in patients with chronic obstructive pulmonary disease (COPD). Following successful completion of a PR programme in Norwich(see below) patients will be randomised to receive maintenance PR or standard medical care.
Prior to enrolment in the PR programme, patients will undergo standard baseline assessments, after providing informed consent. These will include a medical examination, demographic details, past medical history, spirometry, an incremental shuttle walk test (ISWT) to determine a predicted maximum oxygen consumption, an endurance shuttle walk test (ESWT) at 85% of predicted maximum oxygen consumption (V02), chronic respiratory questionnaire (CRQ), EuroQol (EQ5D), hospital anxiety and depression score (HADS), serum interleukin(IL)-6 and C-reactive protein (CRP), body mass index (BMI), skinfold thickness and muscle strength.
At the end of PR and twelve months following PR patients will undergo medical examination, ESWT at 85% of predicted maximum VO2, CRQ, EQ5D, HADS, serum interleukin(IL)-6 and CRP, BMI, skinfold thickness and muscle strength and an assessment of activity in the preceding month.
At 3 months, 6 months and 9 months following PR patients will complete the CRQ and a questionnaire to assess activity in the preceding month. These will be undertaken by postal questionnaire.
Baseline socioeconomic and costs questionnaire will be completed at entry to the PR and follow-up cost questionnaires will be completed following PR and after 3, 6, 9 and 12 months. Patients will be given a diary card on which to record NHS contacts, prescriptions etc at all visits.
The 3, 6 and 9-month questionnaires will be collected by post.
