Notes: IMS PharMetrics Plus database from January 1, 2009 to December 31, 2013. Population used is the one identified for Objective 2. All-cause visits were defined as any inpatient or outpatient visit related to any diagnosis; COPD-related visits were identified as inpatient or outpatient visits in which a diagnosis code for COPD is the primary diagnosis code associated with that visit (or discharge claim for an inpatient visit). Inpatient and ED visits were limited to one per day; outpatient visits were limited to one per provider per day; length of stay was truncated for stays over 365 days; COPD exacerbation severity was evaluated regardless of cause by definition of the algorithm. Mean, SD, median, and range were reported for the entire population.

Abbreviations: ED, emergency department; HRU, health care resource utilization; SD, standard deviation.
