Patient assessment and selection for pulmonary rehabilitation.

Pulmonary rehabilitation (PR) is beneficial for people with several forms of chronic respiratory disease. Given the existing limitations on availability of PR services, it is important to identify participants who are most likely to benefit from it. Identification of criteria for patient referral to PR is challenging, as chronic respiratory diseases and their medical and psychosocial co-morbidities place a complex and multifaceted burden on patients. Although research studies have attempted to identify key parameters predictive of 'responsiveness to PR', to date no firm physiological, psychosocial or other criteria exist by which optimal patient candidacy can be determined. Moreover, individual factors do not reliably predict successful multidimensional PR outcomes. In general, individuals who remain symptomatic with dyspnoea, fatigue and exercise intolerance; who have difficulty performing activities of daily living (ADL); and who are having difficulty coping with or managing their disease despite optimized pharmacological therapy are potential candidates for PR. Patient assessment and outcome measurement are core essential features of PR. To be considered as a PR programme, rehabilitation programmes must demonstrate, at a minimum, assessment and outcome measurement in regard to exercise capacity, dyspnoea and health-related quality of life. Additional parameters, including physical activity, nutritional status, tobacco use status, patient knowledge and self-efficacy, performance of ADL, fatigue, disease exacerbations, hospitalizations and other urgent healthcare utilization, and behavioural outcomes, including coping styles, patient satisfaction and programme metrics, are other relevant and important aspects of patient assessment and outcome measurement that should be considered and undertaken in PR, where feasible.

Pulmonary rehabilitation, physical activity, respiratory failure and palliative respiratory care.

The CIRO Academy in Horn (the Netherlands) organised a 2-day meeting to present and discuss the studies published in 2017 pertaining to key priority areas of respiratory and critical care medicine. This review summarises studies focussing on pulmonary rehabilitation and exercise training, physical activity, chronic respiratory failure and palliative respiratory care published in 2017.

Pulmonary rehabilitation for respiratory disorders other than chronic obstructive pulmonary disease.

Pulmonary rehabilitation (PR) is an important therapeutic intervention that should no longer be considered suitable only for patients with chronic obstructive pulmonary disease (COPD). A strong rationale exists for providing PR to persons with a broad range of respiratory disorders other than COPD. Evidence shows that PR for these patients is feasible, safe and effective. A disease-relevant approach should be undertaken, based on individual patients' needs. Further research is needed to better understand the optimal program content, duration and outcomes measures, to enable diverse patients to achieve maximal benefits of PR.

Defining chronic obstructive pulmonary disease in older persons.

OBJECTIVE: To develop a more age-appropriate spirometric definition of chronic obstructive pulmonary disease (COPD) among older persons. METHODS: Using data from the Third National Health and Nutrition Examination Survey (NHANES III), we developed a two-part spirometric definition of COPD in older persons, aged 65-80 years, that 1) determines a cut-point for the ratio of forced expiratory volume in 1 s to forced vital capacity (FEV1/FVC) based on mortality risk; and 2) among persons below this critical FEV1/FVC threshold, determines cut-points for the FEV1, expressed as a standardized residual percentile (SR-tile) and based on the prevalence of respiratory symptoms and mortality risk. Measurements included spirometry, health questionnaires, and mortality (National Death Index). RESULTS: There were 2480 older participants with a mean age of 71.7 years; 1372 (55.4%) had a smoking history, 1097 (44.2%) had respiratory symptoms and, over the course of 12-years, 868 (35.0%) had died. Among participants with an FEV1/FVC<.70 and FEV1<5th SR-tile, representing 7.7% of the cohort, the risk of death was doubled (adjusted hazard ratio, 2.01; 95% confidence interval [CI], 1.60-2.54). Among participants with an FEV1/FVC<.70 and FEV1<10th SR-tile, representing 13.4% of the cohort, the prevalence of respiratory symptoms was elevated (adjusted odds ratio, 2.44; CI, 1.79-3.33). CONCLUSION: In a large, nationally representative sample of community-living older persons, defining COPD based on an FEV1/FVC<.70, with FEV1 cut-points at the 10th and 5th SR-tiles, identifies individuals with an increased prevalence of respiratory symptoms and an increased risk of death, respectively.

Pulmonary rehabilitation for patients who undergo lung-volume-reduction surgery or lung transplantation.

Patients preparing for or recovering from lung-volume-reduction surgery (LVRS) or lung transplantation represent a selected group of patients with advanced chronic respiratory disease. Such patients typically have severe ventilatory limitation and disability and are at high risk of preoperative and postoperative complications. Pulmonary rehabilitation is an ideal setting in which to: address the patient's questions and knowledge-deficits regarding his or her disease and its treatment; ensure that the patient understands the nature, potential benefits, risks, and expected outcomes of the surgery relative to medical therapies, and; prepare physically and emotionally for the surgery. Pulmonary rehabilitation also may improve survival to and/or outcomes of LVRS and transplantation, at least in part by stabilizing and improving the patient's exercise tolerance and muscle function. Further work is needed to determine whether pulmonary rehabilitation can augment the benefits and outcomes of LVRS or lung transplantation, reduce postoperative complications, or improve patient survival to or following the surgery.

Targeting the COPD exacerbation.

Exacerbations of COPD have a profound detrimental effect on the patient and impose a significant burden on healthcare resource utilization. Prevention and treatment of exacerbations are major objectives of the clinical management of COPD. For this approach to be successful, clinicians must combine both pharmacologic approaches and non-pharmacologic strategies aimed at improving the patient's disease management. Non-pharmacologic approaches include those that can be incorporated into the office setting as well as intervention strategies that are integrated into the lifelong management of COPD. These strategies include developing a partnership with the patient and their social supports, encouraging and facilitating smoking cessation, immunizations, proper use of supplemental oxygen, and most importantly, giving the patient the tools to manage their illness appropriately. Moreover there is clear evidence of an irrevocable decline in pulmonary function after each exacerbation, usually resulting in reduced physical activity and impaired skeletal muscle function. Not surprisingly, pulmonary rehabilitation after such events has been shown to prevent relapse, improve survival and enhance patients' overall function after acute exacerbations.
