EHR Source
How many patient lives are represented in your EHR data source?
How many patients contribute both EHR data and claims data to your data source?
What is your approach for linking claims to EHR data?
What tools, methods were used?
How many pediatric patients contribute both EHR and claims data to your data source(s)?
How does this compare to the number in two years prior?
What are your expectations for how this will compare with the number two years from now?
For patients with both EHR and claims data, how much of a patient’s observation time is overlapping between both EHR and claims data, on average?
On average, how many visits or encounters (e.g., hospitalization, office visit, lab draw) does a patient have in your EHR data source per year?
How many patients have at least one visit in the EHR data in each of the last three years?
Are the following data elements available from your EHR data for analysis?
