The difference between an EHR and an EMR is:
An EMR (Electronic Medical Record) is practice-specific. An EHR (Electronic Health Record) is designed for interoperability — data can follow the patient across providers.
2 / 5
CPOE (Computerised Provider Order Entry) allows:
CPOE replaces handwritten orders — clinicians enter prescriptions, lab tests, and radiology orders directly into the EHR, improving legibility and enabling real-time clinical decision support.
3 / 5
Clinical Decision Support (CDS) in an EHR provides:
CDS augments clinical decision-making — alerting clinicians to drug interactions, suggesting appropriate screenings, flagging abnormal lab values, and recommending evidence-based order sets.

An 'order set' in an EHR is:
Order sets standardise care for common conditions — a sepsis order set might include blood cultures, antibiotics, IV fluids, and vital sign monitoring, ensuring nothing is missed.

In healthcare IT, 'interoperability' means:
Healthcare interoperability allows different systems (hospitals, labs, pharmacies, payers) to exchange and understand clinical data — the goal FHIR, SMART, and the 21st Century Cures Act pursue.
