PatientOS is a free healthcare information management system designed for hospitals and healthcare practitioners. This software is for physicians, nurses, pharmacist, the laboratory, and eventually all hospital departments and clinicians.


This version adds the foundation code to support the creation and maintenance of a formulary. Pharmacists can create medications and rules for dose checking. Medications may be created by defining dose and dispense details to build the formulary. Order templates can be created, which default all the necessary fields for safe medication orders. Sample source code is available to demonstrate a custom import from an external formulary source.
