Prescription drugs: elderly enrollee reports of financial access, receipt of free samples, and discussion of generic equivalents related to type of coverage.
OBJECTIVE
To compare elderly health plan enrollee's survey responses regarding access to prescription drugs, receipt of samples, and discussion of generic equivalents across healthcare delivery systems and to examine the extent to which member characteristics are related to responses.


METHODS
Cross-sectional, observational study.


METHODS
Elderly enrollees (aged 65 and over) in the Preferred Provider Organization (PPO in = 10,2201) and Medicare cost contract (n = 14,635) of a single health insurer responded to a 2001 member satisfaction survey. Multivariable logistic regression was used to estimate the relationship between outcomes (eg, not filling prescriptions) and patient characteristics.


RESULTS
Elderly enrollees in a PPO had more comprehensive drug coverage and better access to pharmaceuticals than Medicare enrollees, with 14% of Medicare enrollees reporting that they "occasionally" or "always" skipped filling prescriptions due to cost, compared with 6% of PPO members (P < .001). Similarly, 14% of Medicare enrollees reported taking less medication than prescribed to save money, compared with 7% of PPO members. Ethnicity was one of the strongest predictors of financial access to pharmaceuticals among elderly enrollees, with the predicted probability of "occasionally" or "never" filling medications ranging from 0.06 for Japanese to 0.16 for Filipinos. A majority of members in both health plans reported receiving free samples of pharmaceuticals from their physicians.


CONCLUSIONS
Further research is needed to determine which medications are not being filled, the impact of sampling on subsequent drug utilization, and specific chronic conditions for which more extensive coverage is cost effective.
