Update in pulmonary rehabilitation

Pulmonary rehabilitation (PR) is an evidence-based set of therapeutic tools and disciplines that attends to the multiple needs of patients with chronic obstructive pulmonary disease (COPD). As the effects of drug therapy are limited, PR contributes significantly to the optimization of COPD medical management by a comprehensive approach that typically comprises exercise and functional training, education and self-management, nutritional counseling and psychosocial skills. To date, the specific value of each component, the best training modality and PR setting as well as the ideal approach in promoting adherence to programs still need elucidation. Nonetheless, it is quite clear that multidisciplinary PR program ameliorates individual's physical performance and improves independence and quality of life of COPD patients. Additionally, it lessens stay in hospital and reduces health care costs due to COPD long-term management. Although it might be effective in all patients with symptomatic COPD, PR is currently available to a relatively small percentage of a large patient population who could benefit.
