Note: Medicare beneficiaries limited to noninstitutionalized population (e.g.,
excludes those in nursing homes) age 65 and older.
a. An odds ratio > 1 indicates elderly Medicare beneficiaries with this
characteristic were more likely not to have purchased at least one prescription
drug in 2001 because of cost. Similarly, those with an odds ratio < 1 were
less likely not to have purchased at least one prescription drug in 2001 because
of cost. For example, an odds ratio of 1.61 for African Americans shows that
African Americans were significantly more likely than non-Hispanic whites to
report not purchasing one prescription drug.
b. Individuals were classified as having a chronic condition if they reported
seeing a doctor or other health professional for at least one of the following
conditions in the past two years: diabetes, arthritis, asthma, COPD (chronic
obstructive pulmonary disease), coronary heart disease (includes angina, arterial
fibrillation, congestive heart failure, bypass surgery, angioplasty, heart disease,
myocardial infarction), hypertension, cancer and/or depression.
