My main use case for LAMP Stack Ubuntu is for a localized patient management system, which is a PMS, and I typically use it for private clinics and specialized medical centers. We use it to build custom electronic medical records or PMS tools.
A specific example of how I use LAMP Stack Ubuntu for my custom electronic medical record tools is that we use OpenEMR on Ubuntu in the healthcare context for a private clinic. We deploy OpenEMR to handle our day-to-day operations.
The kinds of daily operations or tasks that the system handles for the clinics mainly involve multilingual support and customizable forms, e-prescribing, and billing and insurance.
