Guidelines for Chronic Obstructive Pulmonary Disease Treatment and Issues of Implementation

Abstract

Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. Treatment advances over the last decade, although limited, have precipitated the development of clinical practice guidelines, with the aim of improving the quality of care received by patients through fostering evidence-based decision making and accelerating the application of new advances to everyday practice. Of the COPD guidelines that have been developed, those developed through the Global Initiative for Chronic Obstructive Lung Disease (GOLD), initially a joint activity between the U.S. National Heart, Lung, and Blood Institute and the World Health Organization, and the National Institute of Clinical Excellence (NICE) in the United Kingdom have both published their methods for evaluation of evidence. These comprehensive guidelines cover all aspects of the disease, with the aim of providing the basis for local care pathways. The guideline development process includes evaluation of the evidence, development of the guideline, and dissemination of the findings. Efforts to enhance guideline effectiveness have focused on improving the methods and approaches to implementation, which requires an appreciation of the issues that stop translation of guideline definitions of best practice into improved patient care. A variety of questions remain unanswered in the clinical management of COPD, including the definition of outcome measures that move beyond lung function, the potential application of multidimensional grading systems that assess respiratory and systemic expressions of COPD and that could possibly better categorize and predict outcome in these patients, and the impact of new clinical trial findings. Large ongoing outcome studies may also have an effect on defining best practice within future guideline recommendations.
