PatientOS is a free EMR system for physician offices and clinics. The
system is designed to scale and evolve to be a fully fledged
healthcare information system for hospitals.

Version 0.40 adds an HL7 laboratory result inbound interface
(ORU^R01). The messages match on the Patient by identifier (e.g. MRN)
and post the Orders (OBR) and multiple results (OBX) into the patients
chart.

A basic result viewer has been added to the chart. Similar to
scheduling it is designed for plug-in to control the retrieval and
rendering of the lab results to allow for precision control of the
display.

PatientOS version 0.40 includes a demonstration web based Patient
Portal. Patients can login and submit a progress form which is filed
into their chart. The portal account can be created for the patient in
the registration view. The portal is implemented using struts and
shows how the service facade provided by the J2EE application server
enterprise java beans can be accessed from a remote web server.

The patients chart includes a Flowsheet tab which displays the
discrete details submitted via the Patient Portal. There is no limit
on the number of data points that can be captured and displayed.

The LOINC database of lab tests has been uploaded along adding some
standardized functionality to upload CSV files into target tables.

Basic communication orders can be created. The patient chart includes
an orders tab which can add, sign, complete or cancel the order.

An email service has been added to allow the composition of text or
HTML emails.

A Batch Scheduler has been created. Batch Jobs can be defined and
executed at scheduled times. Scheduling is similar to CRON. Batch Jobs
are scripts written in Javascript which can directly access the models
and services. An example script which queries for the state of an
order on the patient and sends an email can be found in JIRA
