What is EMR and EHR?

An EMR (electronic medical record) is the digital version of a patient’s chart within one hospital or clinic. An EHR (electronic health record) is a broader record designed to be shared across providers over time. In India, ABDM standards and ABHA linking are moving hospitals from isolated EMRs towards shareable, consent-based EHRs.

Why it matters for hospitals

Records shape the patient’s experience of continuity, from follow-up to second opinions. For marketing, they matter mainly as a boundary: clinical data should not flow into campaigns without clear legal basis and consent.

How to put it into practice

  • Choose EMR systems that follow ABDM standards for future record sharing.
  • Let patients access their records through an app or portal; it is a strong reason to stay.
  • Keep marketing systems separate from clinical records and use only consented, minimal data.
  • Train doctors on EMR use, as poor adoption creates gaps in continuity.
  • Review access logs and data protection controls regularly.

The common mistake

Using EMR diagnosis data to target marketing messages without specific consent, which can breach DPDP rules and patient trust.

An illustrative example

A hospital added report and prescription access to its patient app, linked to its EMR. Follow-up bookings through the app grew. (Composite example, not a specific hospital.)
