Effects of a comprehensive, inpatient pulmonary rehabilitation programme in a cachectic patient with very severe COPD and chronic respiratory failure

Occupational therapy in pulmonary rehabilitation programs: A scoping review

Pulmonary rehabilitation (PR) is a multidisciplinary intervention forming the cornerstone of chronic respiratory disease management, improving individuals' exercise capacities and abilities to complete activities of daily living (ADLs). Although the occupational therapy (OT) scope of practice focuses on similar outcomes as PR, the tasks/roles and benefit of including OT in PR has not been reviewed. This scoping review synthesized the i) tasks/roles, ii) recommendations of guidelines, iii) prevalence and iv) effects of OT as part of PR programs. Searching of four databases (MEDLINE, EMBASE, CINAHL and Cochrane), OT association websites, and hand searching was performed, and 51 records were included. The OT tasks/roles most reported include teaching energy conservation techniques (n = 23), addressing ADLs (n = 17), and assisting with breathlessness management (n = 10). Using the Canadian Model of Occupational Performance and Engagement these tasks/roles were grouped into person (n = 16 unique tasks/roles), occupation (n = 6 tasks/roles), environment (n = 5 tasks/roles), and other (n = 3 tasks/roles) domains and were endorsed by two available practice guidelines addressing OT in PR programs. From 13 PR surveys across four continents, 17-92% of PR programs included OT. Inclusion of OT in PR resulted in positive effects on ADLs, pulmonary function, dyspnea, quality of life, and mortality. Although an increasing number of PR programs include occupational therapists in their multidisciplinary teams, there is a paucity of original studies and guidelines reporting on the tasks/roles and benefits of OT in PR. Further research is needed to clearly define the tasks/roles of OT in multidisciplinary PR teams and contributions to enhancing patient outcomes.

Update on the Etiology, Assessment, and Management of COPD Cachexia: Considerations for the Clinician

Cachexia is a commonly observed but frequently neglected extra-pulmonary manifestation in patients with chronic obstructive pulmonary disease (COPD). Cachexia is a multifactorial syndrome characterized by severe loss of body weight, muscle, and fat, as well as increased protein catabolism. COPD cachexia places a high burden on patients (eg, increased mortality risk and disease burden, reduced exercise capacity and quality of life) and the healthcare system (eg, increased number, length, and cost of hospitalizations). The etiology of COPD cachexia involves a complex interplay of non-modifiable and modifiable factors (eg, smoking, hypoxemia, hypercapnia, physical inactivity, energy imbalance, and exacerbations). Addressing these modifiable factors is needed to prevent and treat COPD cachexia. Oral nutritional supplementation combined with exercise training should be the primary multimodal treatment approach. Adding a pharmacological agent might be considered in some, but not all, patients with COPD cachexia. Clinicians and researchers should use longitudinal measures (eg, weight loss, muscle mass loss) instead of cross-sectional measures (eg, low body mass index or fat-free mass index) where possible to evaluate patients with COPD cachexia. Lastly, in future research, more detailed phenotyping of cachectic patients to enable a better comparison of included patients between studies, prospective longitudinal studies, and more focus on the impact of exacerbations and the role of biomarkers in COPD cachexia, are highly recommended.
