Abstract

Objective: To report rates of cost-related skipping of medications and other treatments, assess correlates of skipping, examine changes in skipping between 1998 and 2000, and identify factors associated with changes in skipping.

Design, setting, and participants: Cross-sectional and longitudinal analyses of surveys of a probability sample of Medicare beneficiaries in 13 states in 1998 and 2000.

Main outcome measure: Self-reported rates of skipping medications and other treatments.

Results: Cost-related skipping rates increased from 9.5% in 1998 to 13.1% in 2000. In separate multivariable models using 1998 and 2000 data, higher out-of-pocket costs, lower physician-patient relationship quality, low income, and lacking prescription drug coverage were associated with more skipping (P<.05 for all). Better physical and mental health, and greater age were associated with less skipping (P<.05). HMO membership was not associated with higher rates of skipping in 1998 (P=.84), but was in 2000 (P<.0004). In longitudinal analyses, increased medication costs and HMO membership were associated with the observed increase cost-related skipping between 1998 and 2000.

Conclusions: Cost-related skipping was associated with several factors, including drug coverage, poverty, poor health, and physician-patient relationship quality. The important role of physician-patient relationships in cost-related skipping has not been shown previously. Physicians should be aware of these risk factors for cost-related skipping, and initiate dialogue about problems paying for prescription medications and other treatments.
