Traditionally, consumers in, well, traditional plans tend to be way more satisfied with their health plan than others with less traditional plans, such as a high-deductible health plan or a consumer-driven health plan. Though traditional health plan holders still remain happiest with their plan, with the boom in consumer-driven health plans, that satisfaction gap is now narrowing.

So says the Employee Benefit Research Institute, which found the overall satisfaction rate among CDHP enrollees is gradually increasing, while it is gradually decreasing among traditional enrollees.

In 2013, 44 percent of traditional-plan participants were extremely or very satisfied with out-of-pocket costs (for health care services other than for prescription drugs), while 31 percent of CDHP participants were extremely or very satisfied. Satisfaction has been trending upward among CDHP enrollees in recent years, EBRI said in a research brief.
