Role of clinical questionnaires in optimizing everyday care of chronic obstructive pulmonary disease

Figures & data

Figure 1 Symptom frequency in individuals with COPD (evaluation of worst three-month period in past year). Patients participating in the Confronting COPD in America survey were asked about the frequency of their symptoms during their worst three-month period in the past year (ie, “Has there been any three-month period in the past year when you experienced … [read item] – every day, most days a week, a few days a week, a few days a month, less than that?”). A high proportion of patients reported that they frequently experienced specific disease-associated outcomes during their worst period in the past year.³⁶

Figure 2 Relationship between health status as measured by the SGRQ, and FEV₁ and GOLD stage. Patients’ perception of symptoms and health-related quality of life, as assessed by the SGRQ, were not well correlated with objective pulmonary function measurements, such as FEV₁ and GOLD stage.
