A study by Jithoo et al compared the case finding strategies for COPD using data from the Burden of Obstructive Lung Disease study and their results supported the use of PEFR as a simple, cost-effective initial screening tool for conducting COPD case-finding in adults aged >40 yrs.
Case-finding options for COPD: results from the Burden of Obstructive Lung Disease study.
Results from the Population-based Burden of Obstructive Lung Disease
Five-year follow-up of participants diagnosed with chronic airflow obstruction in a SA Burden of Obstructive Lung Disease
6MWD: Six minute walk distance; ATS: American Thoracic Society; BOLD: Burden of Obstructive Lung Disease; ERS: European Respiratory Society; FEV1: Forced Expiratory Volume in one second; FVC: Forced Vital Capacity; GOLD: Global Initiative for Obstructive Lung Disease; IAP: Indoor Air Pollution; PM10: Particulate Matter < 10 [mu]
Patients eligible for inclusion completed the multidimensional written BOLD (Burden of Obstructive Lung Diseases) questionnaire.
The study, which surveyed 878 people aged 40 years or more in Vancouver, Canada, was part of the Burden of Obstructive Lung Disease
(BOLD) Initiative that sought to determine the prevalence of COPD in adults over 40 years in the general population.
In South Africa (SA), a Burden of Obstructive Lung Disease
(BOLD) study performed in two low- to middle-income suburbs of Cape Town in 2005 confirmed a very high prevalence of CAO (Global initiative for Obstructive Lung Disease (GOLD) stage [greater than or equal to] 2) in both men and women aged [greater than or equal to] 40 years; 22.2% of men and 16.7% of women had evidence of CAO, compared with a global average of 10.1% in similar studies performed in countries with a range of socioeconomic status.
