Title: Class variables for MEPS expenditure imputations
Publication: MEPS Methodology Report No. 20. Available on the MEPS Web site
Date: March 15, 2007
Abstract: The Medical Expenditure Panel Survey collects data on health care utilization, expenditures, sources of payment, insurance coverage, and health care quality measures. The survey was designed to produce national and regional estimates for the U.S. civilian noninstitutionalized population. The data on medical expenses are collected from both household respondents in the Household Component and from a sample of their health care providers in the Medical Provider Component. In the absence of payment information from either component, expenditure data are derived for sample persons through an imputation process. Missing expense data are imputed at the event level for each medical event type using a weighted hot-deck procedure. This process utilizes individual- and event-level data collected in MEPS that are correlated with medical expenditures. Bivariate analyses and linear regression models were utilized to assess the current class variables used for imputation. This paper details the methodology used to select, prioritize, and categorize the class variables used to impute missing expenditures for two event types: doctor visits and inpatients hospitalizations. (Previously published as Working Paper #4005, December 2004.)

Title: Trends in the use and expenditures for COX-2 inhibitors and traditional nonsteroidal anti-inflammatory drugs, 1997-2003
Publication: MEPS Statistical Brief No. 139. Available on the MEPS Web site
Date: Sept. 2006
Abstract: This statistical brief uses data from the Household Component of MEPS (MEPS-HC) to document trends in use and expenditures for COX-2 inhibitors from 1997 to 2003 in relation to trends for traditional nonsteroidal anti-inflammatory drugs (NSAIDs). All trends are presented for the total civilian noninstitutionalized population and then separately for the Medicare noninstitutionalized population, who are heavier users of the NSAID class of drugs. This analysis is limited to spending on prescribed medications since MEPS-HC excludes expenditures for over-the-counter medications.

Title: Trends in the pharmaceutical treatment of hypertension, 1997-2003
Publication: MEPS Research Findings No. 25. Available on the MEPS Web site
Date: July 2006
Abstract: Using nationally representative data from the MEPS-HC, this report examines trends in the use of five classes of anti-hypertensive drugs (diuretics, beta blockers, calcium channel blockers, angiotensin-converting enzyme (ACE) inhibitors, and angiotensin II receptor blockers) from 1997 through 2003. The sample for the study is comprised of U.S. adults, ages 18 and older, who reported treatment for hypertension. In addition to aggregate trends, the report also examines trends within and differences across subgroups of the population.

Title: Out-of-pocket health care expenses by age and insurance coverage, 2003
Publication: MEPS Statistical Brief No. 126. Available on the MEPS Web site
Date: May 2006
Abstract: This statistical brief uses data from MEPS-HC for 2003 to examine levels of out-of-pocket payments for individuals in the U.S. civilian noninstitutionalized population with expenses for health care. Estimates are shown according to age and insurance coverage, since levels of out-of-pocket expenses differ substantially according to these characteristics.
