## What it is
OpenMRS is an open-source, patient-based electronic medical record (EMR) system built in Java, providing both an API and a web application. It is designed to be highly customizable for healthcare delivery, especially in resource-constrained environments, with REST and FHIR APIs for interoperability.

## Use cases
- deploy an open-source EMR for a hospital or clinic
- manage patient medical records electronically
- build a customizable medical records system for low-resource settings
- integrate an EMR with other health systems via FHIR or REST APIs
- self-host an electronic health record platform
- adapt an EMR to specific clinical programs like HIV, TB, or maternal care

## When to choose
- you need a free, open-source EMR with no licensing fees or vendor lock-in
- you operate in resource-constrained environments and need a scalable medical records platform
- you require deep customization of clinical workflows and forms
- you need FHIR/REST interoperability with other health information systems

## When to avoid
- you need a turnkey, out-of-the-box commercial EHR with vendor support
- your team cannot budget for implementation, training, and maintenance
- you only need lightweight patient scheduling or billing rather than full medical records
- you lack Java/web deployment expertise or infrastructure
