What are EHRs?

Electronic health records (EHRs) are digital versions of patients’ medical records.

Each time you get healthcare, your doctor and other providers enter information into your EHR, including:

  • Personal information such as your age, gender, and race
  • Current and past health problems and symptoms
  • Test results
  • Medicines and treatments

RECOVER researchers can link data across the United States from different EHRs used by healthcare providers, hospitals, and other medical facilities. They can also link with other data sources, like vaccine records, to get a more complete picture of COVID and Long COVID in the real world.

Why do we study EHRs?

We study EHRs to look for patterns in groups of people, such as who Long COVID affects and for how long.

Looking at EHR health data (also called real world data or observational data) lets RECOVER researchers:

  • See a large amount of health data more quickly than with research studies that participants join, and from people who are more diverse in age, race, geographic location, and other aspects
  • Define Long COVID, such as to group people who have similar symptoms into different types of Long COVID
  • Use patterns in people’s symptoms, medicines, and test results to find other people who may have Long COVID
Scientists analysing data

RECOVER is using EHRs to answer questions like these:

How do EHRs help guide future research and treatment?

Since EHRs contain such a large amount of health data, they also help researchers:

  • Find areas for more research, such as to help decide which treatments are most promising and should be tested in clinical trials on Long COVID
  • Find people who may match to take part in clinical trials on Long COVID
