Growth in prescription drug spending among insured elders.
We examine growth in prescription drug use and spending in a well-insured elderly population in 1997 and 2000. We describe the high-cost segment of this population, identifying how it differs from the rest of the elderly regarding use and types of medications, and how stable this group is over time. Drug spending by the insured elderly rose more than 18 percent annually between 1997 and 2000. High-cost elders use more brand-name drugs, treat more conditions, and use more medications per condition. Once an insured elder becomes a high-cost user of prescription drugs, that person is likely to remain so. Our study suggests that a growing population of elderly is using many medications and may require considerable drug management.
