摘要

This Statistical Brief examines changes in asthma medication use and expenditures among adults, age 18 and older, with reported treatment for asthma from 19981999 to 20082009 using nationally representative data from the Household Component and Medical Provider Component of the Medical Expenditure Panel Survey (MEPS-HC, MEPS-MPC). Data from 1998-1999 and 2008-2009 are pooled to increase sample sizes and the precision of estimates, thus results are presented as average annual estimates for these time periods. Expenditures for all years are expressed in constant 2009 U.S. dollars. All differences between estimates discussed in the text are statistically significant at the 0.05 level or better. This Brief begins by presenting results on the use of controllers, relievers, OCS, and two types of controller medications; followed by results on total health care, out-of-pocket health care, and asthma medications expenditures; and finally results on per user total and out-of-pocket expenditures for asthma medications.
