Development of a population-based screening questionnaire for COPD.

COPD is commonly under-diagnosed, in part because people at risk are unaware of the relevant risk factors and do not recognize related symptoms. Providing this information might permit earlier disease identification but the questions chosen should identify those with spirometrically defined airflow obstruction. Using a population-based data set, we have determined which questions identify persons most likely to have airflow obstruction.

Symptom-based questionnaire for identifying COPD in smokers.

Background: Symptom-based questionnaires may enhance chronic obstructive pulmonary disease (COPD) screening in primary care.

Objectives: We prospectively tested questions to help identify COPD among smokers without prior history of lung disease.

Methods: Subjects were recruited via random mailing to primary care practices in Aberdeen, UK, and Denver, Colo.

Symptom-based questionnaire for differentiating COPD and asthma.

Background: Many patients with obstructive lung disease (OLD) carry an inaccurate diagnostic label. Symptom-based questionnaires could identify persons likely to need spirometry.

Objectives: We prospectively tested questions derived from a comprehensive literature review and an international Delphi panel to help identify chronic OLD (COPD) in persons with prior evidence of OLD.

Questions for COPD diagnostic screening in a primary care setting.

Objectives: To test questions usable in an ambulatory clinic to identify persons likely to have chronic obstructive pulmonary disease (COPD).

Methods: Analyses were performed as part of a study to identify patients with likely COPD in the Glenfield UK primary care clinic. Patients age 40 and older were recruited based on one of the following criteria: (1) respiratory medications in previous 2 years; (2) history of smoking or (3) history of asthma with no current medications based on case notes.

Comparison of existing symptom-based questionnaires for identifying COPD in the general practice setting.

Objective: Underdiagnosis of COPD is widespread, at least in part due to underuse of spirometry. Symptom-based questionnaires may be helpful as an adjunct to spirometry. The aim of this study was to determine which types of questions might aid in identifying COPD.

The impact of chronic obstructive pulmonary disease on long-term disability costs.

Objectives: Chronic obstructive pulmonary disease (COPD) as a cause of disability with subsequent costs remains poorly recognized. The small, growing body of literature on COPD shows that it is one of the leading causes of missed work.greater than asthma or diabetes.

Smoking-related diseases: the importance of COPD.

Setting: Smoking plays a major role in a variety of diseases. Despite a strong relationship between smoking and chronic obstructive pulmonary disease (COPD), cardiovascular disease and lung cancer attract greater attention.

Objective: To assess the burden of illness produced by smoking.

[Experience in long-term use of berodual in the treatment of patients with chronic obstructive bronchitis].

Aim: To study clinical efficiency of 12-month administration of berodual in chronic obstructive bronchitis (COB).

Materials And Methods: The trial entered 33 patients with at least 2-year history of COB and forced expiratory volume per 1 sec (FEV1) not less than 45% of normal value.

Results: The best response of clinical parameters and external respiration was observed throughout 3 weeks of berodual inhalations.

[Comparative study of the effectiveness of equivalent doses of the preparation ditek, disodium cromoglycate and fenoterol in atopic bronchial asthma].

18-45-year-old patients with atopic bronchial asthma free of associated inflammatory diseases received ditek, lomudal and berotek (28, 10 and 10 patients, respectively). Biochemical assessment of allergic inflammation activity demonstrated that ditek is most effective of the above three drugs both in relation to induction of clinical remission and to inhibition of allergic inflammation.
