Blue Cross Blue Shield Association has unveiled the results of its latest survey of Consumer Driven Health Plans (CDHP) [here and here]. This year's presentation reveals that:

• BCBS enrollment in CDHPs has grown 50% in the last year, with 2.9 million in HSA programs and 1.5 million in HRAs.

• Distribution of age and income matches very closely with the distribution for non-CDHP enrollment.

• People who choose a CDHP want to have more control over costs and utilization.

• Compared to people in a non-CDHP plan, people with HSAs are far more likely to ask their doctor about the cost of a recommended treatment (52% to 33%), choose a lower cost option (36% to 23%), and use mail order for buying Rx (43% to 30%).

• They are also far more likely to track their health care expenses (72% to 40%), estimate future expenses (38% to 22%), and discuss expenses with their doctor (38% to 27%).

• They are about 50% more likely to participate in wellness programs.

• They are slightly more likely to use preventative services and equally likely to receive necessary services and comply with prescribed treatment.

• Savings due to reduced utilization equal $1,074 per member in full replacement groups and $615 for multiple choice groups.

• Still, this year for the first time, CDHP enrollees are somewhat less likely to recommend the coverage to others (38% to 45%).
