Do you think the "free" preventive care items included in ACA policies will have a positive impact on patient behavior?
It's a bit of a conundrum, really.
On the one hand, yes, it should encourage people to seek preventive care more regularly by removing all financial barriers. For most people, it's a clear benefit.
On the other hand, so far we've seen very little utilization of preventive care from people who were previously long-term uninsured. It seems that they either don't know how to use their insurance, or that the uninsured contains a high proportion of people in the "skeptical/non-trusting" personality profile. That is to say, there is a smallish category of people who resist being told what to do, even when it's clearly in their best interests and clearly to their benefit. There appears (based on our predicitive modeling and segmentation algorithms) to be a larger proportion of this type of personality in the long-term previously uninsured group than in the group of people who have had insurance more regularly. I have no explanation to causality, only correlation.
On the gripping hand... there are a lot of services that ACA classes as preventive, and that are now covered with no cost sharing... but which are not cost-effective. The cost to perform the tests on a larger segment of people significantly outweighs the cost of treating the disease identified at a later date. Early detection doesn't reduce the cost to treat by enough to offset the cost to screen. That might sound cold-hearted at first glance... but for some of the screenings, the condition is very rare, and is very treatable even if found later. I can't think of them right now, and I'm lazy so I'm not going to dig out my big book of ACA-related stuff and hunt them down.
For consideration, we can talk about colon cancer. Colonoscopies get a lot of press, and are one of the preventive screenings that ACA requires to be free to the insured individual. But they're also relatively pricey - the average cost is around $3000 (significant range from $600 to $4000 or so with variation by geography and negotiated agreement). But colon cancer has a strong genetic component - most people aren't really at risk for it. And most colon cancer shows perceivable symptoms relatively early, at which point it's still quite treatable. Stage I, IIA, and IIIA all have survival rates better than 85%, Stages IIB and IIIB have rates better than 60%.
A reasonable and efficacious approach might recommend colonscopies for people with a family history of colon cancer, but not for anyone else. The colonoscopy would catch cases for people at risk (presumably) at Stage I. The symptoms themselves will catch the vast majority of the remaining people - especially if effort were put in to educating people about the symptoms of early-stage colon cancer. The survival rates would still be better than they are for *most* other cancers (notable exceptions being breast cancer and Hodgkins Lymphoma). But the aggregate cost burden would be lower - which translates to lower premium rates as well as lower cost trend.
So yes, "free" preventive care will have a positive impact on the low utilization associated with high-deductible and HSA plans... but I'm not entirely convinced that "free" results in an aggregate benefit.
