What factors influence seniors desire for choice among health insurance options? Survey results on the Medicare prescription drug benefit

Questions about the design of the new US Medicare prescription drug benefit were raised even before its passage, where one of the most heated issues has been the number of plans offered to beneficiaries. Whether beneficiaries believe that there should be extensive or limited choice is still an open question. To study this issue, we analyzed data from the Kaiser Family Foundation/Harvard School of Public Health Survey, which included 718 individuals aged 65 years and above. The survey asked these older adults (i) whether they prefer having dozens of plans or for Medicare to offer a restricted number of plans and (ii) whether they think there are too many, too few or the right amount of plans. Our findings show that the majority of beneficiaries (69%) preferred that Medicare offer a limited number of options while only 29% wanted to see dozens of plans on the market. We also examine the effect of education level, income, political affiliation, race and health status on the desire for more or fewer plans. One surprising finding is that seniors with higher education appear to prefer fewer, not more, plan choices. Overall, our results question the merit of offering so many prescription drugs plan choices to Medicare beneficiaries.
