EMR vs EHR vs HMS vs PHR: what's the difference?
These four terms are often used as if they mean the same thing. In short: an EMR is one provider's clinical record, an EHR is a record designed to follow the patient between providers, an HMS runs the hospital's operations, and a PHR belongs to the patient.
At a glance
| Who owns it | What it holds | Example use | |
|---|---|---|---|
| EMR (electronic medical record) | One clinic or hospital | Diagnoses, notes, prescriptions, results at that provider | A doctor reviewing last month's visit |
| EHR (electronic health record) | Shared across providers | A patient's record from many providers, built to be exchanged | A specialist seeing a GP's history |
| HMS / HIS (hospital management or information system) | The hospital | Operations: registration, appointments, beds, theatres, pharmacy, billing, plus the EMR | Running the OPD queue and billing |
| PHR (personal health record) | The patient | Reports, prescriptions, readings and history the patient keeps | A family keeping parents' reports in one place |
How they fit together in India
ABDM (Ayushman Bharat Digital Mission) links these pieces: patients get an ABHA number, facilities register in the Health Facility Registry, and records can move between providers with the patient's consent. A hospital's HMS holds its EMR; the patient's PHR app can receive copies; consent decides who sees what.
Where QueroCura fits
QueroCura has both ends: a hospital management system with a clinical record for providers, and CuraVault, a personal health record for patients and families, connected by the patient's consent.
Frequently asked questions
Is an HMS the same as an EMR?
No. An HMS runs hospital operations (appointments, beds, pharmacy, billing) and usually contains an EMR, which is the clinical record.
What is a PHR?
A personal health record: the patient's own collection of reports, prescriptions and readings, which the patient controls.
