Electronic Health Record (EHR)

The digital record of a patient's health information across providers — and the system clinicians spend most of their screen time inside.

Industry & Domain

An EHR holds a patient's longitudinal clinical record — history, medications, allergies, results, notes — and is designed to be shared across providers. An EMR is narrower, usually one practice's own record. The distinction matters commercially because interoperability obligations attach to the former, and it matters to design because a shared record means reconciling data entered by people with different conventions.

EHR interfaces are a well-documented source of clinician burnout, and the causes are consistent: documentation burden driven by billing rather than care, alert fatigue from warnings that fire constantly and are dismissed reflexively, and information density that buries the clinically relevant detail. Any product touching an EHR inherits this context — a new alert is not a neutral addition, it joins a stream clinicians have already learned to ignore.

Integration means HL7 FHIR

Most modern EHR integration runs through FHIR APIs, with access, scopes and vendor-specific behaviour that shape what a connected product can actually show.

In practice

A clinical decision tool added an alert for a drug interaction. Clinicians dismissed it in under a second at a 94% rate, because it joined about 60 daily alerts. Restricting it to the two highest-severity combinations cut firing by 80% and raised the rate at which it changed a prescribing decision from near zero to 12%.

Where teams get it wrong

  • Adding alerts to a stream clinicians already dismiss reflexively.
  • Designing for the administrator who buys rather than the clinician who uses.
  • Treating documentation burden as a compliance constant rather than a design problem.
  • Assuming EHR data is clean, structured and consistently coded.
  • Ignoring that the record is shared, so conventions differ by contributing provider.

Frequently Asked Questions

What is the difference between an EHR and an EMR?

An EMR is one practice's own clinical record. An EHR is designed to follow the patient across providers, which brings interoperability requirements and the problem of reconciling data entered under different conventions.

Why do clinicians dislike EHR systems?

Documentation driven by billing rather than care, alert fatigue from warnings that fire constantly, and interfaces dense enough to bury the clinically relevant detail. All three are consistently cited in burnout research.
