Using Tools as Designed [Letter]
MeiLan Han, Barry Make, Barbara P Yawn · International Journal of COPD · 2022
We read with interest the article by Zhou et al 1 comparing six COPD screening tools in a Chinese population that presented to the Department of Respiratory and Critical Care Medicine of the China Medical University. We applaud this study and its recognition of the importance of assessing COPD screening tools in populations with varying cultural, ethnic, language and health backgrounds. The patients in this study clearly represent a special population of those with sufficient concern to bring them to specialty respiratory care and with high rates of prior and current smoking, low BMIs and average age of >55 years.
