According to a survey by Americas Health insurance Plans (AHIP) the number of individuals insured by high-deductible health plans (HDHPs) in conjunction with health savings accounts (HSAs) grew 18.4% this year to 13.5 million from 11.4 million in 2011. AHIP data shows that this type of consumer-driven health plan (CDHP) has increased gradually since it was introduced in 2004. Read more about AHIP’s survey at Workforce.com.

One question arises from the aforementioned survey: Do CDHPs help reduce costs? Jack Burke and Rob Pipich’s detailed analysis on high-deductible plans found that when adjustments are made for typical risk and benefit factors, CDHPs deliver cost savings that are modestly better than non-CDHPs. Here is an excerpt:
“Most employers we examined showed savings in the CDHP plan before adjusting for risk and plan design characteristics; however, the bulk of the apparent savings was explained by these adjustments. After adjustments, the reduction in combined employer and employee costs averaged 4.8% before accounting for the utilization-dampening impact of the high deductible. Accounting for the high deductible made the reduction 1.5%. Some employers showed significantly greater reductions.”
This 1.5% reduction is what’s known as “induced utilization” and is a key element of CDHPs. For more, read Milliman’s complete Consumer-Driven Impact Study.
