Background
Marketscape leverages several data sources to provide you with the best market intelligence available. Use the tables below to understand how often the data source gets updated and the type of metrics that each data source includes. Many of the sources come from the CMS Virtual Research Data Center (VRDC).
How does the data get from CMS to me?
Trella Health analyzes data compiled from billions of claims, which represents hundreds of billions of individual data points. The following image simplifies the process.
This image sure seems to say it all, but let's add some details:
Most of the ideas that generate our new metrics come in as ideas or questions from our users.

Our Product Teams evaluate and prioritize ideas and requests. Sometimes they consult with users to clarify usage and needs. If the new metric (or feature) is deemed useful and valuable, a lot happens:

Now Data Science has a huge job!

This is where the Trella Health "black-box" comes in. The algorithms we use to massage and squeeze the raw data from the claims into what we need is our trade secret. The result, however, is a mammoth collection of patient counts and performance metrics aggregated from every Medicare FFS claim! It is important to remember that we do more than just provide you with a dump of raw data. After we get the data, we do some careful analysis in order to provide meaningful metrics that tell a specific story. (And some of that analysis is our "secret sauce" that makes us the leader in medical analytics - hence the black box!) An example: we don't just count every patient discharged from a hospital who was admitted to hospice care in the same year. Although this "raw" count would have some value, we want to focus on referral potential, providing you with the opportunity to act where the potential is high. We count the number of patients entering hospice care within 30 days of discharge in order to identify a "logical" connection between the hospital and admission to hospice care. |

Finally, the thousands of resulting counts and scores and percentages are organized into pages and tables in a way that is easy to browse, sort, filter and discover. In this way, the metric you originally requested is drawn out of the mass of data collected from all Medicare claims and displayed in Marketscape or Mosaic for you to use.

In the tables below, other data sources are listed. In many ways, the process for turning raw data into useful metrics is the same for all of the data sources listed.
