Link data across disparate sources

RWE allows providers, payers and pharma companies to integrate data from multiple sources. This can include clinical data from EMR or EHR records, transactional data from claims files, pharmacy data from various databases and unstructured data from handwritten records and social media sites.

Linking this data can yield new insights --such as discovering that a slightly less effective but much less expensive medicine is more cost effective for a given population. It also increases data reliability -- since different sources for the same data can be compared against one another -- and consistency. For example, data on the same patient can be reconciled even though it was generated by different systems (e.g. private insurance versus Medicare) and stored in different databases.
