The concept of control of COPD in clinical practice. Int J Chron Obstruct Pulmon Dis. 2014; 9:1397-4051176-9106http://hdl.handle.net/10668/2386Journal Article;Treatment of chronic obstructive pulmonary disease (COPD) requires a personalized approach according to the clinical characteristics of the patients, the level of severity, and the response to the different therapies. Furthermore, patients with the same level of severity measured by the degree of airflow obstruction or even with multidimensional indices may have very different symptoms and limitations for daily activities. The concept of control has been extensively developed in asthma but has not been defined in COPD. Here, we propose a definition of COPD control based on the concepts of impact and stability. Impact is a cross-sectional concept that can be measured by questionnaires such as the COPD Assessment Test or the Clinical COPD Questionnaire. Alternatively, impact can be assessed by the degree of dyspnea, the use of rescue medication, the level of physical activity, and sputum color. Stability is a longitudinal concept that requires the absence of exacerbations and deterioration in the aforementioned variables or in the COPD Assessment Test or Clinical COPD Questionnaire scores. Control is defined by low impact (adjusted for severity) and stability. The concept of control in COPD can be useful in the decision making regarding an increase or decrease in medication in the stable state.enCOPDControlCATCCQExacerbationsPrognosisEnfermedad Pulmonar Obstructiva CrónicaEncuestas y CuestionariosPulmónProgresión de la EnfermedadRecuperación de la funciónÍndice de severidad de la enfermedadValor predictivo de las pruebasResultado del tratamientoMedical Subject Headings::Organisms::Eukaryota::Animals::Chordata::Vertebrates::Mammals::Primates::Haplorhini::Catarrhini::Hominidae::HumansMedical Subject Headings::Anatomy::Respiratory System::LungMedical Subject Headings::Phenomena and Processes::Genetic Phenomena::PhenotypeMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Epidemiologic Research Design::Sensitivity and Specificity::Predictive Value of TestsMedical Subject Headings::Diseases::Respiratory Tract Diseases::Lung Diseases::Lung Diseases, Obstructive::Pulmonary Disease, Chronic ObstructiveMedical Subject Headings::Phenomena and Processes::Biological Phenomena::Recovery of FunctionMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Diagnostic Techniques and Procedures::Diagnostic Techniques, Respiratory System::Respiratory Function TestsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Investigative Techniques::Epidemiologic Methods::Data Collection::Health Surveys::Health Status Indicators::Severity of Illness IndexMedical Subject Headings::Information Science::Information Science::Data Collection::QuestionnairesMedical Subject Headings::Phenomena and Processes::Physical Phenomena::Time::Time FactorsMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Diagnosis::Prognosis::Treatment OutcomeMedical Subject Headings::Diseases::Pathological Conditions, Signs and Symptoms::Pathologic Processes::Disease Attributes::Disease ProgressionMedical Subject Headings::Health Care::Health Care Quality, Access, and Evaluation::Quality of Health Care::Health Care Evaluation Mechanisms::Data Collection::Surveys and Questionnairesresearch article25548521open access10.2147/COPD.S713701178-2005PMC4271723
