Public Health, Colorado All Payer Claims Database

In a recent article in the Journal of the American Medical Association, economists from Stanford and Massachusetts Institute of Technology (MIT) did a very interesting thing. There is a general assumption that the richer you are, the longer you live, on average. This turns out to be true. But why does increasing income mean increasing lifespan? These economists tested that hypothesis by using two related data sources: tax returns and Social Security Administration death records. Using these two databases, they were able to map life expectancy by income level across different “commuting zones” around the country, over a five year period. This involved roughly 1.4 billion tax records over that time.
The results are fascinating. Some of the conclusions:
What else correlated with increased lifespan for the poor? In addition to the factors above, they were the tried and true behavioral factors we already know about: lower smoking and obesity rates and higher exercise rates.
There is much more in this study, and I will continue to ponder its findings. But in an oversimplified way, this tells me that the best way to improve the health of communities may not be to get them more health care. The best way might be to alter the health habits of low income residents. There may also be sound societal reasons for trying to clean up the environment, reduce income inequality, and reduce unemployment, but improving the health of the population isn’t one of them, at least according to the correlations found in this study.
The other thing we should notice is that this study took massive amounts of computing power. Manipulating 1.4 billion records is no small feat, but we are likely to see more studies like this because of the emergent force of big data. We should see these kinds of insights with increasing frequency as analytics get ever more powerful.
The Colorado All Payer Claims Database (CO APCD) was recently updated with Medicaid and commercial health insurance information through 2014, and has new data on chronic disease prevalence (diabetes, asthma, hypertension, and depression) by county and other new measures like breast, cervical and colorectal cancer screening rates. The CO APCD combined with other social determinants of health data provide a rich source of information for Colorado to begin investigating opportunities to improve health by evaluating variation across regions and demographics.
