Chronic obstructive pulmonary disease (COPD) remains a major public health problem. It is the fourth leading cause of chronic morbidity and mortality in the United States, and is projected to rank fifth in 2020 in burden of disease worldwide, according to a study published by the World Bank/World Health Organization. Yet, COPD remains relatively unknown or ignored by the public as well as public health and government officials. In 1998, in an effort to bring more attention to COPD, its management, and its prevention, a committed group of scientists encouraged the U.S. National Heart, Lung, and Blood Institute and the World Health Organization to form the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Among the important objectives of GOLD are to increase awareness of COPD and to help the millions of people who suffer from this disease and die prematurely of it or its complications. The first step in the GOLD program was to prepare a consensus report, Global Strategy for the Diagnosis, Management, and Prevention of COPD, published in 2001. The present, newly revised document follows the same format as the original consensus report, but has been updated to reflect the many publications on COPD that have appeared. GOLD national leaders, a network of international experts, have initiated investigations of the causes and prevalence of COPD in their countries, and developed innovative approaches for the dissemination and implementation of COPD management guidelines. We appreciate the enormous amount of work the GOLD national leaders have done on behalf of their patients with COPD. Despite the achievements in the 5 years since the GOLD report was originally published, considerable additional work is ahead of us if we are to control this major public health problem. The GOLD initiative will continue to bring COPD to the attention of governments, public health officials, health care workers, and the general public, but a concerted effort by all involved in health care will be necessary.

Representatives from many countries serve as a network for the dissemination and implementation of programs for diagnosis, management, and prevention of COPD. The GOLD Board of Directors is grateful to the many GOLD National Leaders who participated in discussions of concepts that appear in GOLD reports.

Global initiative for chronic obstructive lung disease.

Background: Pulmonary rehabilitation is recognized as a core component of the management of individuals with chronic respiratory disease. Since the 2006 American Thoracic Society (ATS)/European Respiratory Society (ERS) Statement on Pulmonary Rehabilitation, there has been considerable growth in our knowledge of its efficacy and scope.

Purpose: The purpose of this Statement is to update the 2006 document, including a new definition of pulmonary rehabilitation and highlighting key concepts and major advances in the field.

Methods: A multidisciplinary committee of experts representing the ATS Pulmonary Rehabilitation Assembly and the ERS Scientific Group 01.02, “Rehabilitation and Chronic Care,” determined the overall scope of this update through group consensus. Focused literature reviews in key topic areas were conducted by committee members with relevant clinical and scientific expertise. The final content of this Statement was agreed on by all members.

Results: An updated definition of pulmonary rehabilitation is proposed. New data are presented on the science and application of pulmonary rehabilitation, including its effectiveness in acutely ill individuals with chronic obstructive pulmonary disease, and in individuals with other chronic respiratory diseases. The important role of pulmonary rehabilitation in chronic disease management is highlighted. In addition, the role of health behavior change in optimizing and maintaining benefits is discussed.

Conclusions: The considerable growth in the science and application of pulmonary rehabilitation since 2006 adds further support for its efficacy in a wide range of individuals with chronic respiratory disease

An official American thoracic society/European respiratory society statement: Key concepts and advances in pulmonary rehabilitation

Background The widespread application pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) should be preceded by demonstrable improvements in function attributable to the programs. This review updates that reported by Lacasse et al Lancet 1996; 748:1115-1119. Objectives To determine the impact of rehabilitation on health-related quality of life (QoL) and exercise capacity in patients with COPD. Search strategy The 14 randomized controlled trials (RCTs) included in the original meta-analysis were included. Additional RCTs were identified from the Cochrane Airways Group's registry of COPD RCTs using the strategy: [exp, lung diseases, obstructive] and [exp, rehabilitation or exp, exercise therapy] and [research design or longitudinal studies or evaluation study or randomized controlled trial]. Abstracts presented at American Thoracic Society 1980-2000, American College of Chest Physicians 1980-2000 and European Respiratory Society 1987-2000 were also searched. Selection criteria RCTs of rehabilitation in patients with COPD in which quality of life (QoL) and/or functional (FEC) or maximal (MEC) exercise capacity were measured. Rehabilitation was defined as exercise training for at least 4 weeks with or without education and/or psychological support. Control groups received conventional community care without rehabilitation. Data collection and analysis Weighted mean differences (WMD) were calculated using a random-effects model. Missing data from the primary study reports were requested from the authors. Main results 23 RCTs met the inclusion criteria. Statistically significant improvements were found for all the outcomes. In three important domains of QoL (Chronic Respiratory Questionnaire scores for Dyspnea, Fatigue and Mastery), the effect was larger than the minimal clinically important difference of 0.5 units using this instrument. For example Dyspnoea score: WMD 0.98 units, 95% Confidence Interval (95% CI) 0.74 - 1.22 units; n=9 trials. For FEC and MEC, the effect was small and a little below the threshold of clinical significance for the 6- minute walking distance: WMD 49 m, 95% CI: 26 - 72 m; n=10 trials. Reviewer's conclusions Rehabilitation relieves dyspnea and fatigue and enhances patients' sense of control over their condition. These improvements are moderately large and clinically significant. The average improvement in exercise capacity was modest. Rehabilitation forms an important component of the management of COPD.

American Thoracic Society/European Respiratory Society Statement on Pulmonary Rehabilitation

Background Self-management interventions improve various outcomes for many chronic diseases. The definite place of self-management in the care of chronic obstructive pulmonary disease (COPD) has not been established. We evaluated the effect of a continuum of self-management, specific to COPD, on the use of hospital services and health status among patients with moderate to severe disease. Methods A multicenter, randomized clinical trial was carried out in 7 hospitals from February 1998 to July 1999. All patients had advanced COPD with at least 1 hospitalization for exacerbation in the previous year. Patients were assigned to a self-management program or to usual care. The intervention consisted of a comprehensive patient education program administered through weekly visits by trained health professionals over a 2-month period with monthly telephone follow-up. Over 12 months, data were collected regarding the primary outcome and number of hospitalizations; secondary outcomes included emergency visits and patient health status. Results Hospital admissions for exacerbation of COPD were reduced by 39.8% in the intervention group compared with the usual care group ( P = .01), and admissions for other health problems were reduced by 57.1% ( P = .01). Emergency department visits were reduced by 41.0% ( P = .02) and unscheduled physician visits by 58.9% ( P = .003). Greater improvements in the impact subscale and total quality-of-life scores were observed in the intervention group at 4 months, although some of the benefits were maintained only for the impact score at 12 months. Conclusions A continuum of self-management for COPD patients provided by a trained health professional can significantly reduce the utilization of health care services and improve health status. This approach of care can be implemented within normal practice.

Reduction of Hospital Utilization in Patients With Chronic Obstructive Pulmonary Disease: A Disease-Specific Self-management Intervention

BACKGROUND
Self-management interventions improve various outcomes for many chronic diseases. The definite place of self-management in the care of chronic obstructive pulmonary disease (COPD) has not been established. We evaluated the effect of a continuum of self-management, specific to COPD, on the use of hospital services and health status among patients with moderate to severe disease.


METHODS
A multicenter, randomized clinical trial was carried out in 7 hospitals from February 1998 to July 1999. All patients had advanced COPD with at least 1 hospitalization for exacerbation in the previous year. Patients were assigned to a self-management program or to usual care. The intervention consisted of a comprehensive patient education program administered through weekly visits by trained health professionals over a 2-month period with monthly telephone follow-up. Over 12 months, data were collected regarding the primary outcome and number of hospitalizations; secondary outcomes included emergency visits and patient health status.


RESULTS
Hospital admissions for exacerbation of COPD were reduced by 39.8% in the intervention group compared with the usual care group (P =.01), and admissions for other health problems were reduced by 57.1% (P =.01). Emergency department visits were reduced by 41.0% (P =.02) and unscheduled physician visits by 58.9% (P =.003). Greater improvements in the impact subscale and total quality-of-life scores were observed in the intervention group at 4 months, although some of the benefits were maintained only for the impact score at 12 months.


CONCLUSIONS
A continuum of self-management for COPD patients provided by a trained health professional can significantly reduce the utilization of health care services and improve health status. This approach of care can be implemented within normal practice.

Reduction of hospital utilization in patients with chronic obstructive pulmonary disease: a disease-specific self-management intervention

The aim of the present study was to assess the long-term impact on hospitalisation of a self-management programme for chronic obstructive pulmonary disease (COPD) patients. A multicentre, randomised clinical trial was carried out involving 191 COPD patients from seven hospitals. Patients who had one or more hospitalisations in the year preceding study enrolment were assigned to a self-management programme "Living Well with COPD(TM)" or to standard care. Hospitalisations from all causes were the primary outcome and were documented from the provincial hospitalisation database; emergency visits were recorded from the provincial health insurance database. Most patients were elderly, not highly educated, had advanced COPD (reflected by a mean forced expiratory volume in one second of 1 L), and almost half reported a dyspnoea score of 5/5 (modified Medical Research Council). At 2 years, there was a statistically significant and clinically relevant reduction in all-cause hospitalisations of 26.9% and in all-cause emergency visits of 21.1% in the intervention group as compared to the standard-care group. After adjustment for the self-management intervention effect, the predictive factors for reduced hospitalisations included younger age, sex (female), higher education, increased health status and exercise capacity. In conclusion, in this study, patients with chronic obstructive pulmonary disease who received educational intervention with supervision and support based on disease-specific self-management maintained a significant reduction in hospitalisations after a 2-year period.
