According to American Lung Association, COPD (chronic obstructive pulmonary disease) is the third leading cause of death in the United States. This study was initially proposed to assist in decision making for an oxygen machine manufacturer. More specifically, an estimate of COPD prevalence was required as a reference to their sales plan development. A method of COPD estimation using spatial statistics was developed and realized in R. This method works with the United States Census and COPD statistics by characteristics from BRFSS (Behavioral Risk Factor Surveillance System), and the results can be obtained in most levels below the state level, such as county and ZCTA (ZIP Code Tabulation Areas). The method was evaluated by being performed and compared with COPD hospitalizations (crude rates) in the state of Florida, and the method was proven to be practical.
