Pulmonary rehabilitation: summary of an evidence-based guideline

Abstract

Pulmonary rehabilitation has emerged as a standard of care for patients with chronic lung disease, based on a growing body of scientific evidence. Over recent decades, several organizations have championed pulmonary rehabilitation and developed comprehensive statements, practice guidelines, and evidence-based guidelines. Documenting the scientific evidence underlying clinical practice has been important in overcoming skepticism and convincing health professionals, health-care institutions, third-party payers, and regulatory agencies to support pulmonary rehabilitation programs. The literature on pulmonary rehabilitation has increased substantially and provided justification for including pulmonary rehabilitation in practice guidelines for chronic obstructive pulmonary disease and other chronic lung diseases. Therefore, the American College of Chest Physicians and the American Association of Cardiovascular and Pulmonary Rehabilitation decided to update their 1997 guidelines with a systematic, evidence-based review of the literature since the previous review. The panel updated prior topics and recommendations and reviewed new topics. Recommendations were given for outcomes of comprehensive pulmonary rehabilitation programs, including lower-extremity exercise training, dyspnea, health-related quality of life, health-care utilization, survival, psychosocial outcomes, and long-term benefits. Additional topics include the duration of pulmonary rehabilitation, post-rehabilitation maintenance strategies, intensity of aerobic exercise training, strength training, anabolic drugs, upper-extremity training, inspiratory-muscle training, education, psychological and behavioral components, oxygen supplementation, noninvasive ventilation, nutrition supplementation, rehabilitation for patients with disorders other than chronic obstructive pulmonary disease, and future pulmonary rehabilitation research. These guidelines provide an excellent summary of the recent literature and further strengthen the scientific basis of pulmonary rehabilitation.
