Background and Objective: There is no strong evidence on the optimal duration of pulmonary rehabilitation (PR) programmes. The aim of the study was to determine whether an 8-week PR programme was equivalent to a 12-week PR programme in improving endurance exercise capacity in people with chronic obstructive pulmonary disease (COPD)., Methods: Participants with COPD were randomized to either an 8-week (8-wk Group) or 12-week (12-wk Group), twice weekly, supervised PR programme consisting of endurance and strength training and individualized self-management education. Between group comparisons were made at completion of each programme (i.e., week 8 or week 12), for both programmes at week 12, and at 6-12-month follow-up. The primary outcome was endurance exercise capacity measured by the endurance shuttle walk test (ESWT) with the minimally important difference of 186 s set as the equivalence limit., Results: Sixty-six participants [mean (SD); age 69 (7) years, FEV 1 48 (17) %predicted] were randomized (33 per group). Between-group comparisons demonstrated that the ESWT time was equivalent for the 12-wk Group compared to the 8-wk Group at programme completion [mean (95% CI)] [71 s (-61 to 203)], week 12 [70 s (-68 to 208)], and 6-12-month follow-up [93 s (-52 to 239)], though superiority of the 12-wk Group could not be ruled out at each time point., Conclusion: Equivalence was shown between 8-and 12-week PR programmes for endurance exercise capacity, but superiority could not be ruled out for the 12-wk Group. Decisions about programme duration may depend on local waitlist times, healthcare budgets and patient preference., (© 2024 The Author(s).

Pulmonary complications in CTD are common and can involve the interstitium, airways, pleura and pulmonary vasculature. ILD can occur in all CTD (CTD-ILD), and may vary from limited, non-progressive lung involvement, to fulminant, life-threatening disease. Given the potential for major adverse outcomes in CTD-ILD, accurate diagnosis, assessment and careful consideration of therapeutic intervention are a priority. Limited data are available to guide management decisions in CTD-ILD. Autoimmune-mediated pulmonary inflammation is considered a key pathobiological pathway in these disorders, and immunosuppressive therapy is generally regarded the cornerstone of treatment for severe and/or progressive CTD-ILD. However, the natural history of CTD-ILD in individual patients can be difficult to predict, and deciding who to treat, when and with what agent can be challenging. Establishing realistic therapeutic goals from both the patient and clinician perspective requires considerable expertise. The document aims to provide a framework for clinicians to aid in the assessment and management of ILD in the major CTD. A suggested approach to diagnosis and monitoring of CTD-ILD and, where available, evidence-based, disease-specific approaches to treatment have been provided., (© 2020 The Authors.

Pulmonary rehabilitation (PR) improves exercise capacity, health-related quality of life (HRQoL) and dyspnoea in patients with COPD and other lung conditions. Once PR is completed, the benefits gained begin to decline unless patients continue to exercise regularly. Due to limited evidence in other lung conditions, this review aims to examine the current evidence regarding maintenance exercise programmes for patients with COPD and to determine the types of programmes that are able to maintain the benefits gained from PR to 12 months and longer. A number of factors may affect the ability to maintain exercise capacity and HRQoL in the long term including: frequency of supervised maintenance exercise; strategies used to improve adherence to maintenance exercise; facilitators and barriers to long-term exercise training; and initial PR programme itself. The current evidence for maintenance exercise programmes that included supervised maintenance exercise was weak, and for those programmes that included unsupervised maintenance exercise (with and without support) were difficult to interpret and in many instances were no better than usual care. New research using technology has provided some promising results for the future and surveys have revealed important features that may help in the development of maintenance programmes from a participant perspective such as ongoing therapist support. How to best maintain the benefits gained from PR remains unclear. Therefore, it is likely that no one model of maintenance is ideal for all patients with COPD and that individually adapted maintenance exercise programmes need to be considered., (© 2019 Asian Pacific Society of Respirology.)

Background and Objective: The aim of the Pulmonary Rehabilitation Guidelines (Guidelines) is to provide evidence-based recommendations for the practice of pulmonary rehabilitation (PR) specific to Australian and New Zealand healthcare contexts., Methods: The Guideline methodology adhered to the Appraisal of Guidelines for Research and Evaluation (AGREE) II criteria. Nine key questions were constructed in accordance with the PICO (Population, Intervention, Comparator, Outcome) format and reviewed by a COPD consumer group for appropriateness. Systematic reviews were undertaken for each question and recommendations made with the strength of each recommendation based on the GRADE (Gradings of Recommendations, Assessment, Development and Evaluation) criteria. The Guidelines were externally reviewed by a panel of experts., Results: The Guideline panel recommended that patients with mild-to-severe COPD should undergo PR to improve quality of life and exercise capacity and to reduce hospital admissions; that PR could be offered in hospital gyms, community centres or at home and could be provided irrespective of the availability of a structured education programme; that PR should be offered to patients with bronchiectasis, interstitial lung disease and pulmonary hypertension, with the latter in specialized centres. The Guideline panel was unable to make recommendations relating to PR programme length beyond 8 weeks, the optimal model for maintenance after PR, or the use of supplemental oxygen during exercise training. The strength of each recommendation and the quality of the evidence are presented in the summary., Conclusion: The Australian and New Zealand Pulmonary Rehabilitation Guidelines present an evaluation of the evidence for nine PICO questions, with recommendations to provide guidance for clinicians and policymakers., (© 2017 The Authors.
