The Medicare Electronic Health Record (EHR) Incentive Program provides incentives to eligible clinicians and hospitals to adopt electronic health records. This dataset combines meaningful use attestations from the Medicare EHR Incentive Program and certified health IT product data from the ONC Certified Health IT Product List (CHPL) to identify the unique vendors, products, and product types of each certified health IT product used to attest to meaningful use. The dataset also includes important provider-specific data, related to the provider's participation and status in the program, unique provider identifiers, and other characteristics unique to each provider, like geography and provider type.

This dataset provides the proportion of developers, by market share, that have certified 2015 edition health IT modules. Market share approximations are determined through an analysis of the certified health IT products reported by participants in the Medicare EHR Incentive Program from 2011 to 2016. Approximations use the most recently reported data for each unique clinician and hospital participant. It is important to understand how to interpret these approximations. Some clinicians and hospitals report certified software from more than one unique developer. The market share percentages in this dataset, therefore, include some double counting (the percentages will, if summed together, add up above 100 percent.) The approximations convey the percent of hospitals and clinicians who use a developer's technology, and are not to be interpreted in aggregate as the percent of all hospitals and clinicians who have access to 2015 edition certified technology.

The CMS EHR Incentive Programs provide incentives to eligible office-based providers and hospitals to adopt electronic health records. Both the Medicare and Medicaid programs have separate criteria and eligible participants. These measures track the percentage of physicians, nurse practitioners, physician assistants, short-term general, Critical Access, and Children's hospitals that have demonstrated meaningul use of certified electronic health record technology and/or adopted, implemented, or ugraded any electronic health record. These measures track the rate of adoption and use of EHR technology certified by HHS in addition to adoption of other non-certified EHR technology. These measures are cumulative, representing the most recent data.
