Chronic obstructive pulmonary disease (COPD) affects 5% of the adult population in the United States, but a general screener has not been evaluated for the disease at a large scale. In this paper we evaluate a COPD screener using an innovative application of sampling weights. With these sampling weights, we explore the different cut off points and variables to use in the screener. We found that the optimal variable on the pocket screener was peak expiratory flow with an ideal cutoff of 0.91.
