Aetna Research on the Benefits of Improving Oral Health
Our DMI program was launched in 2007. It was the result of research that Aetna completed with Columbia University College of Dental Medicine, where we found that members with Diabetes, CAD and CVD who were receiving dental care had an average of 27% lower risk scores.
In addition, we found that members with those conditions who had been treated over time for periodontal (gum) disease had an average of 12% lower medical costs. An additional study with Columbia showed that pregnant members who received dental care had 25% lower preterm delivery rates and 34% fewer incidents of low birth weight. Seeing those results made us want to encourage more of our members with those conditions to visit the dentist.
For members with those medical conditions, the DMI program includes postcard outreach for members who have not recently visited the dentist. The postcards provide education on the important connections between oral health and overall health. An additional feature of the program is enhanced dental benefits for DMI members, such as an extra cleaning and periodontal services covered at 100%.* A very important differentiator of the DMI program, compared to our competitors’ programs, is that we automatically identify members for the program and the outreach and enhanced benefits are automated as well. Members don’t even have to know about the program and they do not have to fill out any forms. Our unique program creates engagement in our members! Since the program began, over 1.5 million members have been identified and DMI members have received over $30 million in enhanced benefits.
There is no cost to plan sponsors or members for DMI, and an average of about 7% of a client’s members can be impacted by these medical conditions, although we have seen it as high as 20% for some clients.
Since the DMI program has been in place, we have been evaluating outcomes for our DMI members. Compared to a statistically matched control group without the DMI program, DMI members receive 10% more preventive dental care, and 42% less basic and major dental treatment.4 We also found that DMI members had an average of 17% lower medical costs. While these statistics typically apply to a small group of employees – around 7% - these members are the ones who can benefit from dental care the most, based on our published research. Another interesting finding is that looking year over year, DMI members had a 3.5% reduction in hospital admissions, compared to a 5.4% increase in admissions for the control group. For members with diabetes, we found that those in DMI had a 45% improvement in diabetes control over time. A member with diabetes that is well controlled (meaning that they have HbA1c results of less than 7,) can save about $7.49 PMPM compared to a member who is not well controlled.
In a recent blog post, Mark Bertolini was quoted as saying the following at a healthcare reform conference: “While many may be talking about change, we are driving change.” This really sums up what our DMI program is all about.
